Full textAbstract:
The nanoindentation or indenter testing technique (ITT) is a functional and fast technique that can give us a lot of information about the mechanical properties of different materials at nanometric scale, from soft to brittle materials. The principle of the technique is the evaluation of the response of a material to an applied load. In a composite material, if the size of the residual imprint resulting from a certain load is lower than the size of the studied phase, then it is possible to determine its mechanical properties, and therefore its contribution to the global mechanical properties of the composite. Depending on the tipped indenter used, different equations should be applied to study the response of the material, and thus calculate stress-strain curves, and parameters such as hardness, Young's modulus, toughness, yield strength and shear stress. These equations are related to the different deformation mechanisms (elastic and elasto-to-plastic) that the material undergoes. In the case of most of the ceramic composites, when a spherical tipped nanoindenter is used, elastic deformation takes place, and Hertz equations can be used to calculate the yield strength, shear stress and the strain-stress curves. On the other hand, when a Berckovich indenter is used, plastic deformation takes place, then Oliver and Pahrr equations must be applied to evaluate the hardness, Young's modulus and toughness. Nevertheless, in the hardness study, Indentation Size Effect (ISE) must be considered.
The mechanical properties of a ceramic superconductor material have been studied. YBa2Cu3O7-ä (YBCO or Y-123) samples textured by Bridgman and Top Seeding Melt Growth (TSMG) techniques have been obtained, and their mechanical properties studied by nanoindentation. This material presents a phase transition from tetragonal to orthorhombic that promotes a change in its electrical properties, from insulating to superconductor, and that can be achieved by partially oxygenating the material. On the other hand, the structure of the textured material is heterogeneous, and two different phases are present: Y-123 as a matrix and Y2BaCuO5 (Y-211) spherical or quasi-spherical inclusions. Moreover, the texture process induces an anisotropic structure, thus being the ab-planes the ones that transport the superconductor properties while the c-axis remains insulating. Nowadays, efforts are focused on the production of long length Superconductor Materials. Silver welding is a technique that allows us to join several TSMG samples thus trying to obtaining larger samples. Nevertheless, one important factor to be accounted for is the mechanical stability across the welding zone, which has been studied in this Thesis.
Another attempt to produce long length superconductor materials is to shape thus as wires or plates. In this case, a metallic sheet, covered with different buffer layers is used as substrate on which YBCO layers can be deposited by PED for example. These structures have been also studied in the present Thesis.

Questa tesi presenta nuova evidenza empirica sulla relazione tra allocazione dei fattori di produzione e differenze di produttivita' tra paesi (primo capitolo) e tra imprese (secondo capitolo). Il primo capitolo analizza la questione degli scarsi movimenti di capitale tra paesi ricchi e paesi poveri (Lucas' paradox). Una calibrazione del modello neoclassico applicata a nuovi dati mostra come, una volta tenuto conto delle differenze nello stock di capitale umano e nella remunerazione del fattore capitale, i rendimenti da capitale fisico sono molti simili tra paesi ricchi e paesi poveri. Il secondo capitolo studia la relazione tra l'allocazione dei fattori fra imprese e la produttivita' totale dei fattori (TFP). Applicando il modello di Hsieh e Klenow (2009) a dati di imprese manifatturiere di Cile e Messico negli anni '80, si nota una minore presenza di distorsioni nell'allocazione dei fattori in Cile. Questa piu' efficiente allocazione dei fattori di produzione tra imprese potrebbe aiutare a capire perche' l'economia cilena, diversamente da quella messicana, recupero' velocemente dopo la crisi dei primi anni '80.This Thesis provides new empirical evidence on the relationship between the allocation of factors of production and differences in productivity across countries (first chapter) and across firms (second chapter). In the first chapter I address the issue of small capital flows between rich and poor countries (the so-called Lucas' paradox) observed in data. Applying a calibration approach to new data I show that, taking into account differences in human capital and in the capital share on output, returns to physical capital in rich and poor countries are fairly close. In the second chapter I investigate the relationship between the allocation of factors across firms within a country and TFP. Applying the model proposed by Hsieh and Klenow (2009) to firm level data of Chile and Mexico during 1980s I find that there are less distortions operating on average in the Chilean manufacturing sector with respect to the Mexican one. I argue that the more efficient allocation of factors across firms could help explain why Chile recovered rapidly while Mexico stagnated after the crisis of the early 1980s.

Devido a crescente necessidade de elevação dos níveis de conformação em peças estampadas em geral, existe uma demanda cada vez maior em ligas e processos diversificados que atendam as variadas exigências do setor de produtos estampados e posteriormente tratados termicamente para aumento de dureza. Desse modo desenvolveu-se a liga C80U modificada, que é uma variante da liga C80U especificada na norma DIN EN ISO 4957 porém com adição de Cromo, entretanto a liga C80U modificada ainda é pouco estudada e pouca informação técnica se tem a seu respeito. Com a finalidade de melhor conhecimento técnico dessa liga, foram conduzidos estudos de caracterização em amostras laminadas a quente e após processo de esferoidização posteriormente sendo revestidas com fosfato de zinco. Foram realizados estudos de composição química, microestrutura, textura cristalográfica, propriedades mecânicas e estrutura do fosfato, além de levantamento da curva CLC através do método Nakazima e evolução da rugosidade 2D e 3D em amostras com e sem revestimento de fosfato, antes e após conformação. Através dos resultados parciais encontrados, foi possível definir o lado da curva CLC relacionado ao estiramento da chapa bem como comparar o deslocamento e a força do punção no teste Nakazima conformando-se amostras esferoidizadas sem revestimento e com revestimento de fosfato.Due to the increasing demand for enhanced formability levels of stamped parts in general, there is also an increasing demand for various alloys and processes that comply with the various requirements associated with stamped products that are subsequently heat treated to increase their hardness. Along this line, a modified C80U alloy has been developed, which is a variant of the alloy C80U specified in the standard DIN EN ISO 4957 but with the addition of Chrome. However, this alloy is still poorly studied and little technical information is available about it. In order to increase the knowledge of this alloy, characterization studies were conducted on hot rolled, after spheroidization and subsequently coated with zinc phosphate samples. The studies performed included chemical composition, microstructure, crystallografic texture, mechanical properties and analysis of the phosphate structure, as well as Nakazima tests in order to obtain the forming limit diagram (FLD) curve and the 2D and 3D roughness evolution of spheroidized samples coated and uncoated before and after the stamping process. Through the partial results obtained, it was possible to define the side of FLD curve related to stretching of the sheet as well as comparing the displacement and force of the punch on Nakazima test, stamping spheroidized samples both uncoated and coated with zinc phosphate.

Full textAbstract:
Red foxes (Vulpes vulpes) are a significant pest species threatening the survival of endangered and vulnerable native Australian fauna. Lethal baiting with the toxin 1080 is currently the most widely implemented form of control. However, non-target uptake is a problem, even in Western Australia where most native species have a high 1080 tolerance. It reduces the number of baits available to foxes and therefore the efficiency and cost-effectiveness of 1080 fox baiting operations. To investigate bait presentation and the use of aversive tastant agents as potential techniques to reduce non-target uptake of 1080 baits, two separate studies were conducted. Study 1 examined different non-toxic meat bait presentations to find the presentation that had the lowest non-target uptake. Baits were laid on the surface, suspended, buried or wrapped in kangaroo hide. Study 2 investigated the effectiveness of potential deterrents in causing aversion both immediately and accumulatively over time. Nine different deterrents (washing-up liquid, citric acid, wasabi, baking powder, bicarbonate soda, salt, sodium saccharin, Bitrex and chilli) were tested for immediate aversion and chilli and Bitrex were tested for accumulative aversion. A cafeteria-style presentation was used, with deterrents applied to apple baits of control, low and high concentrations. For Study 1 and 2 animal activity and bait take were monitored on remote-sensing Reconyx cameras for later photo analysis. The results of Study 1 suggested no significant effect of bait presentation. However, as hypothesised the longevity and non-target uptake was lowest for buried baits. Study 2 suggested that salt, wasabi and chilli created immediate aversion in the most abundant non-target species, quokkas. However, aversion was only carried-over onto untreated apple baits in wasabi and chilli. These findings suggest that bait presentation and the use of aversive tastant agents may have potential to decrease non-target uptake and be employed in future baiting 1080 fox baiting operations.

Full textAbstract:
Aerial control using 1080 (sodium monofluoroacetate) baits is widely used in New Zealand for the control of introduced brushtail possums (Trichosurus vulpecula), with the aim of protecting national conservation and agricultural values from these damaging pests. This thesis integrates research, completed over 25 years, that was motivated by growing recognition in the 1970s of the extent of possum impacts and the need to improve the effectiveness and efficiency of the control operation. Field research assessed the palatability of three types of cereal-based pellet baits and carrot baits in different regions, habitat types and seasons. Palatability was assessed by the consumption of the different bait types presented independently of each other on 15-30 plots, with rotation of bait types at plots on successive nights to provide equal exposure to each bait type. There was regional variation in possums' bait preferences, possibly reflecting genotypic differences, whereas seasonal variation was less evident. Carrot bait was preferred or equally preferred to cereal bait in 14 out of 20 field trials. The proportion of possums eating baits was then investigated by, firstly, developing a technique for tracing bait acceptance using rhodamine B, a UV-fluorescent dye. In four field trials, more than 95% of possums accepted three types of dye-marked bait, eliminating bait refusal as a major reason for low kills in winter control operations. In a fifth trial, conducted in summer, only 68% of possums accepted bait suggesting that seasonal availability of favoured foods may influence bait acceptance. Since possums must encounter baits before deciding whether to eat them, field studies were undertaken to assess the coverage achieved in normal aerial baiting operations. Large gaps, up to 400 m in width, were often found between baiting swaths; these could allow some possums to survive. A controlled field experiment, using acceptance of rhodamine-dyed bait as a measure of effectiveness, showed that bait distribution was least accurate where flight paths were not marked. Where gaps of 100 m between flight paths were deliberately created, bait acceptance was slower and less than where coverage was complete. Sowing baits at 3 kg/ha was as effective as at 10 kg/ha, indicating the potential for substantially reducing operational costs by using machinery capable of faultlessly distributing baits at low rates. Navigational guidance systems were evaluated and found to improve the accuracy of bait distribution. During 1993-1997, when a lower sowing rate of 5 kg/ha was adopted operationally by regional managers, control effectiveness was unchanged but annual savings of around $9 million accrued. Because of the lack of suitable sowing machinery, a bucket was developed to permit faultless distribution of baits at lower rates, demonstrating the possibility of yet further cost-savings. The possibility of seasonal food availability affecting bait acceptance was investigated in three different forest habitats. Dyed baits were aerially distributed on 100 ha at each site in each season over two years. In each trial, fat-based condition indices of possums were calculated and the abundance of possum-preferred plant foods described. Bait acceptance was consistently high (85-100%) in the 24 trials, and was not influenced by either condition or availability of preferred foods. It seems likely that seasonal variation in operational effectiveness is caused by either the availability of sharply seasonal, scarce foods that possums may feed on intensively for brief periods, or by warmer temperatures that render 1080 less effective. The influence of 1080 on acceptance of (rhodamine-dyed) baits was investigated in a field trial. Examination of possums for dye-marking showed that 25% of possums refused to eat either a lethal quantity of bait or any bait at all, compared with 98% of possums eating non-toxic bait. This indicated that 1080 is aversive to possums, which is a potential major reason for their surviving control operations. Pen trials were therefore conducted to further examine the problem and to seek solutions. Toxic carrot baits were rejected by 27.5% of possums, equally by smell and taste aversion, whereas toxic cereal pellets were rejected by 34%, mainly by taste aversion. Orange and cinnamon were shown to be among the most preferred of 42 flavours tested and, when applied to toxic baits, 1080 was effectively masked. Bait refusal was reduced to ≤7%, the same as that recorded for possums presented with flavoured non-toxic baits. For long-term control of possum populations, aerial 1080 baiting can be used sequentially with other poisoning methods. However, the compatibility of these methods is dependent on the likelihood of possums developing bait shyness if sublethally dosed. Studies were therefore conducted to characterise and compare the four main toxicants used (1080, cyanide, cholecalciferol and brodifacoum) for induction and mitigation of bait shyness. Shyness was induced in approximately 80% of possums sublethally dosed with cyanide, 60% with 1080, 20% with cholecalciferol, and 0% with brodifacoum. Cyanide and 1080 shyness were found to persist in many possums for at least 12 and 24 months, respectively. Use of alternative bait types, and of baits containing an alternative slow-acting toxin (brodifacoum) were shown to be effective ways of overcoming shyness. This, and other related research, is reviewed to provide operational specifications that maximise the likelihood that all targeted possums will (i) encounter bait, (ii) eat it, and (iii) die. The likely future use of aerial 1080 baiting is described and the technological, economic, environmental and social constraints on its sustainability are discussed. Finally, the uptake of the research by possum managers is considered, and areas identified in the thesis where information is incomplete are summarised as prioritised topics for further research.

Full textAbstract:
The antitumour activities of 18 benzoic acid and 2-hydroxybenzoic acid analogues were investigated in HT-1080 fibrosarcoma cell line. Several approaches were used to identify the most effective apoptotic agents capable of inhibiting cell population expansion of HT-1080 cells mostly at a concentration of 0.4mM. Techniques used in this study included: cell viability assays (MTT, direct count and time-lapse tracking images), morphology (DAPI, haematoxylin-eosin, methyl green-pyronin y, and SEM), immunocytochemistry (Annexin V, caspase-3) and pharmacology (2-hydroxybenzoate uptake). The results indicated that most of these compounds showed antiproliferative activities at specific concentrations (range 0.025-8mM), with an incubation time of 2-180 hours. It is evident that zinc 2-hydroxybenzoate was the most effective antiproliferative agent at 0.3 and 0.4mM. Other analogues, mainly calcium, also showed antiproliferative activities but at higher concentrations (up to 8mM). The growth inhibitory effect on HT-1080 cells population after treatment with either calcium or zinc 2-hydroxybenzoates was identified as the occurrence of apoptosis. This was confirmed by the morphological techniques as well as by immunoassay including annexin V and caspase- 3, measured by flow cytometry. Although strong evidence has been presented here for apoptosis, the genetic mechanism remains uncertain. Neither the expression of the six proteins p53, p21, Bax, Bcl-2, histones and TNF-a, nor the cell cycle analysis was able to fully elucidate the mechanism of action of calcium and zinc 2-hydroxybenzoate on HT-1080 cells. Nonetheless, calcium and zinc 2-hydroxybenzoate-induced apoptosis clearly involved caspase-3 through Bax and p53/p21, respectively, and displayed the properties of potentially therapeutic compounds.

Jing, Xiamei. "On deformations of compressible hyperelastic material." Thesis, University of Glasgow, 1998. http://theses.gla.ac.uk/1080/.
Full textAbstract:
We consider the character of several finite deformations of compressible isotropic, nonlinear hyperelastic materials, specifically azimuthal shear of a thick-walled circular cylindrical tube, the bending deformation of a rectangular block and axial shear of a thick-walled circular cylindrical tube. For each problem the equilibrium equations are applied to the special case of isochoric deformation, and explicit necessary and sufficient conditions on the strain-energy function for the material to admit such a deformation are obtained. These conditions are examined for several strain-energy functions and in each case complete solutions of the equilibrium equations are obtained. The predictions of the shear response for different strain-energy functions are compared using numerical results to show the dependence of the applied shear stress on the resulting macroscopic deformation. It is then shown how consideration of isochoric deformations in compressible elastic materials provides a means of generating classes of strain-energy functions for which closed-form solutions can be found for incompressible materials. For the problem of bending deformation we find that isochoric deformation is not possible in a compressible material. The conditions for a non-isochoric bending deformation to be admitted by the equilibrium equations are then examined for each of three classes of compressible isotropic materials. Explicit solutions for each case are then derived. Finally, we consider an incremental displacement superimposed on the azimuthal shear of a circular cylindrical tube. Numerical results are obtained to show the incremental displacement and nominal stresses for a special material when the internal boundary is subject to an incremental displacement.

Full textAbstract:
This thesis is comprised of four parts: an introduction to the thesis, an empirical research study, a critical literature review and a case study. The introduction presents an overview of the thesis and illustrates the connecting theme of constructivism in a broad sense as it relates to each section of the thesis. The empirical research study examines the experiences of therapeutic practitioners and aimed to gain a greater understanding of how they may be affected, both personally and professionally, by the characteristics of perfectionism and high levels of impostor fears. Additionally the study also explored how the therapeutic process and therapeutic relationship may also be affected by these two characteristics. Fourteen semi-structured interviews were conducted with therapeutic practitioners then transcribed and analysed using constructivist grounded theory methods. A theory was constructed via the analysis of the data and it outlines a process of developing the view of self as a good enough therapist which emerged from the participants accounts. This study explores the journey of development across the span of the therapists’ careers and the forces which act upon this view of self. The findings of the study suggest that although the therapeutic practitioners interviewed had various levels of perfectionism and impostor fears from across the continuums for both of these characteristics, they all went through a very similar developmental process in order to be able to view themselves as good enough therapists. Additionally, the findings also suggest that the main difference in this developmental process was that the participants with higher levels of perfectionism and/or impostor fears experienced this process at a much more intense level and for a longer duration, with some participants suggesting that they are still in the process of developing a sound view of themselves as good enough therapists even late into their careers. The critical literature review examines the literature on the therapeutic alliance and considers its implications for therapeutic work as well as for future research. The literature review aims to draw together the significant elements that will allow therapists to be able to develop a greater understanding of the alliance and how best to maintain a good alliance in their clinical work. The final part contains the case study which summarises the key features of the therapeutic work undertaken over sixteen sessions of Cognitive Behavioural Therapy. The case study discusses the client’s presenting difficulties, the collaboratively developed formulations and my critical reflections on the work and the relationship.

Full textAbstract:
Il presente contributo prende le mosse dalla consapevolezza che i modelli lineari tradizionali sulle carriere (Super,
1980) hanno lasciato il passo a concettualizzazioni più complesse e non lineari (Cohen, Duberley & Mallon, 2004;
Pryor & Bright, 2007; Richardson, 2002), argomento tra l’altro approfondito operando una disanima delle principali
transizioni di carriera e dei fenomeni psicosociali ad esse correlate (Schlossberg, Waters & Goodman, 1995).
Vengono affrontati temi attuali quali quelli della Globalizzazione riflessiva (Beck, 1999), della complessità e
delle Flessibilità (Sennett, 1998) e se ne mette in luce le interrelazioni con il fenomeno delle carriere, ed in particolare
delle dinamiche che ne hanno modificato progressivamente e radicalmente la natura nel corso degli ultimi trent’anni
(Hall, 1976, 1996). È stato approfondito il tema dei nuovi percorsi di carriera, con particolare attenzione ai costrutti
teorici della Protean Career (Carriera Versatile) e della Boundaryless Career (Carriera senza confini).
Sono stati condotti due studi, mediante il metodo dell’inchiesta, proponendo dei questionari
autosomministrabili a due gruppi di lavoratori dipendenti. La selezione degli strumenti da inserire nel protocollo, e
quindi delle ipotesi da verificare è stata operata in funzione delle caratteristiche intrinseche dei due gruppi coinvolti,
cercando comunque di valorizzare sempre il ruolo dei nuovi orientamenti di carriera all’interno del disegno di ricerca.
Lo studio 1 è stato condotto su un gruppo di 540 lavoratori dipendenti provenienti da Sardegna e Sicilia.
Facendo riferimento agli studi tradizionali sull’insicurezza lavorativa (Sverke & Hellgren, 2002), si è cercato di valutare
l’eventuale effetto moderante dei nuovi orientamenti di carriera (Briscoe, Hall & Frautschy De Muth, 2006) circa gli
effetti dell’insicurezza su benessere psicofisico (Goldberg, 1972) e coinvolgimento lavorativo (Schaufeli, Bakker &
Salanova, 2006; Scaufeli, Salanova, Gonzalez-Romá & Bakker, 2002). I risultati hanno mostrato alcuni effetti parziali,
ma d’altro canto è emerso che i medesimi orientamenti di carriera risultano significativamente e direttamente associati a
variabili quali l’Autoefficacia, la Proattività, il benessere e il Coinvolgimento.
Lo studio 2, riguardante un gruppo di 79 neolaureati di Palermo e provincia al primo inserimento lavorativo, è
stato condotto nell’arco di 8 mesi con tre rilevazioni dati. In questo caso si è cercato di evidenziare eventuali effetti
causali longitudinali degli orientamenti di carriera sulle variabili dipendenti già incluse nello studio 2. Le ipotesi
espresse hanno trovato soltanto parziale conferma nei risultati.

Coverdale, Helen. "Punishing with care : treating offenders as equal persons in criminal punishment." Thesis, London School of Economics and Political Science (University of London), 2013. http://etheses.lse.ac.uk/1080/.
Full textAbstract:
Most punishment theories acknowledge neither the full extent of the harms which punishment risks, nor the caring practices which punishment entails. Consequently, I shall argue, punishment in most of its current conceptualizations is inconsistent with treating offenders as equals qua persons. The nature of criminal punishment, and of our interactions with offenders in punishment decision-making and delivery, risks causing harm to offenders. Harm is normalized when central to definitions of punishment, desensitizing us to unintended harms and obscuring caring practices. Offenders may be partially silenced and excluded by mainstream criminal justice practices which limit interaction between offenders and practitioners. When we ignore significant harms, or silence and exclude, we treat others as passive nonsubjects. This partially objectifies offenders, and is inconsistent with treatment as equals. Penal theories employing harm-centred and harm-normalizing definitions of punishment can provide few resources to help practitioners either avoid, or recognize and respond to, harms. Care ethics, by contrast, motivates the avoidance of harm, ongoing inclusive engagement, and respectful interaction with others. I argue that defining punishment without presupposing harm facilitates the identification of morally problematic harms, and recognition of caring practices. I offer a principled argument, and political and pragmatic supplementary arguments, for responding to offenders without intentional harm and with care. Principles drawn from care ethics can help to strengthen mainstream criminal practices by structuring decision-making and action. Bottom-up alternative criminal justice practices share some values with these proposed guiding principles, allowing a partial test of the principles. I consider examples of restorative justice practices, therapeutic jurisprudence, community justice and other problem-solving court practices, in addition to considering how well mainstream punishment practices measure up to these principles. My analysis illuminates the strengths and weaknesses of the principles, and how they might contribute to securing treatment as equals for offenders in mainstream practices.

Alhassan, Yussif Nagumse. "The role of the National Health Insurance Scheme in shaping equity of access to healthcare in Ghana." Thesis, London Metropolitan University, 2014. http://repository.londonmet.ac.uk/1080/.
Full textAbstract:
In light of recent emphasis on achieving Universal Health Coverage through social health insurance in low income countries, this thesis examined how the National Health Insurance Scheme in Ghana impacts on equity of access to healthcare in Tamale District of northern Ghana. Using mainly a qualitative approach, the thesis specifically examined whether the NHIS promotes equity in health insurance coverage and whether insured members are able to access healthcare equitably. Against this background, four broad findings were identified. Firstly, even though the NHIS improved insurance coverage in the Tamale District, enrolment was largely inequitable because most socially disadvantaged groups/individuals were less able to insure. This was mainly because such groups were predisposed to developing low willingness and low ability to enrol in the NHIS as a result of their individual and community characteristics as well as NHIS and healthcare system factors. Secondly, the NHIS improved the affordability of healthcare services and reduced the risk of catastrophic healthcare expenditure among insured members, particularly insured low income households. Thirdly, while the NHIS improved the financial resources of healthcare providers and the availability of medicines and medical supplies, it adversely impacted on the general quality of healthcare services mainly because the supply of healthcare resources failed to keep up with a high demand for healthcare services by insured members. Fourthly, the NHIS also improved the use of formal care, particularly among insured low income households due to their greater healthcare needs and previous inability to afford the cost of healthcare services. However, due to long waiting times associated with accessing NHIS healthcare, the improvement in financial access to healthcare by the NHIS failed to eradicate the use of ‘informal’ forms of care (e.g. drugstore, herbal/traditional medicine) among insured members. Based on these findings, this thesis concludes that the NHIS could enhance equity in access to care if there are opportunities created to enable socially disadvantaged groups to enrol in the scheme as well as improve the availability and quality of healthcare services for insured members.

Full textAbstract:
In Western Australia dried meat baits containing 1080 are used extensively by agricultural and conservation organisations to control foxes and dingoes for the protection of agricultural production and native fauna. Field trials were conducted to assess 1080 loss from dried meat baits and this required the analysis of over five hundred baits. Because of this large number of baits it was essential to have a simple and efficient 1080 extraction procedure and method of 1080 analysis. In this study three methods of 1080 extraction and the new bioassay method for 1080 analysis were investigated. A simple and cost-effective 1080 extraction method using water with a 98% 1080 recovery rate was developed and modifications to the bioassay method were made.Factory-produced 1080 dried meat baits were laid in the field during different seasons at four locations in Western Australia, samples were collected over time and analysed for 1080 content using the bioassay. Rainfall was recorded and temperature data was collected for each site. Baits were exposed to the elements but were placed in mesh or wire cages to restrict invertebrate attack and prevent removal by vertebrates. Some baits were placed on the surface and others were buried. Initially 1080 loss from baits from all 4 sites was minimal, ranging from 0 - 21% at day 7 - 9. Further loss was gradual even when rainfall was recorded. Generally baits had to be exposed to at least 50 mm of rain before 1080 loss increased to 50%. At some sites baits continued to remain toxic to foxes even after long exposure. The mean 1080 content of baits from the Carnarvon site at day 226 was 2.0 mg (55% of the mean 1080 content of baits at day zero) with 137 mm of rainfall recorded for that period. Loss of 1080 from baits buried occurred at a faster rate than from baits placed on the surface during the same time period. By day 14 no 1080 was detected in the buried baits compared to the 68% detected in the surface baits. Under certain conditions 1080 loss from baits was minimal. Levels of 1080 in baits from Nangeen Hill remained fairly constant during the months of September to December 1995, and again during February to April 1996.Gastrolobium plant tissue and soil samples from the southwest of Western Australia were investigated for the presence of 1080 degrading microorganisms. Microbes were isolated and individually tested in solution containing 1080 as the sole carbon source. Isolates which showed 1080 degrading ability were further tested for their degrading efficiency in McClung carbon-free solution with added 1080 as the sole source of carbon and in factory 1080 waste solution, at 1080 concentrations of 20 and 200 mM. The effect of temperature on their rate of degradation was also examined. Thirteen isolates (7 fungi and 6 bacteria) showing varying degrees of 1080 degrading ability were obtained. Rates of 1080 degradation varied among isolates but were highest in the factory waste solution at the 20 mM concentration and in the McClung solution, where 1080 was the sole source of carbon, at the higher concentration of 200 mM. The most efficient isolates OSK and 10H (both Pseudomonas species) degraded all the 1080 present in sterile factory waste solution up to 20 mM 1080 concentration in 4 days and the isolate 1AF (Fusarium oxysporum) degraded 93% of 200 mM 1080 in the McClung solution in 9 days. The optimum temperatures for 1080 degradation were 30 degrees celsius and fluctuating ambient temperatures of 15 28 degrees celsius.

In Western Australia dried meat baits containing 1080 are used extensively by agricultural and conservation organisations to control foxes and dingoes for the protection of agricultural production and native fauna. Field trials were conducted to assess 1080 loss from dried meat baits and this required the analysis of over five hundred baits. Because of this large number of baits it was essential to have a simple and efficient 1080 extraction procedure and method of 1080 analysis. In this study three methods of 1080 extraction and the new bioassay method for 1080 analysis were investigated. A simple and cost-effective 1080 extraction method using water with a 98% 1080 recovery rate was developed and modifications to the bioassay method were made.Factory-produced 1080 dried meat baits were laid in the field during different seasons at four locations in Western Australia, samples were collected over time and analysed for 1080 content using the bioassay. Rainfall was recorded and temperature data was collected for each site. Baits were exposed to the elements but were placed in mesh or wire cages to restrict invertebrate attack and prevent removal by vertebrates. Some baits were placed on the surface and others were buried. Initially 1080 loss from baits from all 4 sites was minimal, ranging from 0 - 21% at day 7 - 9.

Full textAbstract:
The control of introduced mammalian predators in New Zealand forests is crucial for the protection of native species and essential ecosystem services. Possum control in the form of aerial 1080 applications is conducted by TbFree New Zealand to prevent the spread of bovine tuberculosis, and often has the added conservation benefit of temporarily reducing levels of other mammalian predators such as rodents and mustelids. However, native non-target species such as birds and weta can also be at risk of direct and secondary poisoning following 1080 applications, as well as increased predation risk through mesopredator release. To determine whether the benefits of 1080 applications outweigh the risks to non-target native species, both short and long-term monitoring of populations following aerial 1080 applications is needed.
For this study, two forest regions in the South Island were selected for pre- and post-treatment monitoring of non-target species following an aerial 1080 application for possum control. Each region contained a treatment site and a paired non-treatment site. Relative indicies of possums, rodents and other mammalian predators were obtained using tracking tunnels and chew cards, indicies of birds were obtained using five-minute bird counts, and indicies of tree weta were obtained using tracking tunnels and artificial shelters. Monitoring was conducted before the aerial 1080 was applied in August 2012, and over the following 2012/13 and 2013/14 summer seasons.
The aerial 1080 applications were successful at reducing possums to undetectable levels at both treatment sites for the two seasons following treatment. Mice were significantly reduced at one treatment site relative to the paired non-treatment site immediately following the 1080 operation, but had increased to pre-1080 levels by the second post-treatment monitoring season. Rats were detected at low levels, and showed no response to the treatment. Mustelids were not detected at either region throughout the monitoring period.
No native species showed a decline in a treatment site that was not matched in the non-treatment site. Chaffinches significantly declined at both treatment sites relative to non-treatment sites, likely due to an indirect delayed effect such as competition for food resources. Tomtits showed a positive response to the treatment, significantly increasing in both treatment sites over the post-treatment monitoring periods. Tree weta showed no significant decline in response to the treatment. The reduction of possums to low levels, and the maintenance of possum control with ongoing 1080 operations, is likely to continue to provide an overall net benefit to native non-target species.

Full textAbstract:
Au début du XIe s. Av. J. -C. Byblos va jouir d’une période d’indépendance qui va durer jusqu’au milieu du IXe s. Av. J. -C. Cela est attesté par des différentes sources, telles que le récit égyptien d’Ounamon, le texte assyrien de Tiglath-Phalazar Ier et les inscriptions royales de Byblos. Durant cette période, Byblos rétablissait des relations diplomatiques avec l’Égypte. Ensuite, avec l’arrivée des Assyriens, Byblos, comme les autres villes phéniciennes, a perdu son indépendance et les relations égypto-giblites s’estompent. Après la bataille de Qarqar en 853 av. J. -C. , Byblos n’avait participé à aucune révolte anti-assyrienne et était obligée de payer tribut afin de conserver son autonomie locale. Cette période s’achève avec la chute de l’Assyrie vers 610 av. J. -C. Et la montée de l’empire Babylonien, mais le pouvoir de celui-ci dura moins qu’un siècle. Nous ignorons ce qui s’est passé à Byblos durant cette période, mais d’après les stèles de Nahr al-Kaleb et de WadiBrissa il nous paraît qu’elle était soumise au pouvoir babylonien. Vers l’an 539 av. J. -C. , Babylone tomba entre les mains des Perses qui fondent un vaste empire, de l’Égypte jusqu’à l’Inde. Durant cette période, Byblos profita de la situation politique et économique et connu une prospérité économique remarquable. Cela est bien attesté dans la restauration luxueuse du temple de la BaalatGoubal et dans l’émission des monnaies. De plus, Byblos entrainait des relations avec la ville chypriote de Lapethos. Le pouvoir des Perses au Levant tient jusqu’à l’arrivée d’Alexandre le Grand c’est-à-dire vers l’an 333 av. J. -C. La nouvelle présentation de différentes sources nous ont permis de faire la lumière sur plusieurs points longtemps inconnus dans l’histoire de Byblos durant le premier millénaireIn the early eleventh century B. C. , Byblos enjoyed a period of independence, until the middle ninth century. This is confirmed by several sources like the Egyptian story of Wenamun, an Assyrian text of Tiglath-pileser Iand the royal Byblian inscriptions. During this period, Byblosordered diplomatic relations with Egypt. This period ended when the Assyrian kings arrived in the Levant about the middle of the ninth century B. C. Byblos, like the other Phoenician cities, lost its independence, and its relation with Egypt fade and was obliged to pay tribute in order to retain its local autonomy. In 610 B. C. , the Assyrian power came to an end, but in the other side the Babylonian empire rose. However this one did last less then one century. Unfortunately, we do not know what has happened exactly in Byblos during this period, but the stelae of Nahr al-Kalb and WadiBrissa inform us that the city was completely under the Babylonian power. In 539 B. C. , the Persian took the power and established a vast empire, from Egypt to India. During this period, Byblos benefited from the political and economic situation and knew an economic prosperity. This is well attested in the luxury restoration of the temple of Baalat and the right to mint coins. In addition, Byblos established relations with the Cypriot city of Lapethos. But the Persian power fell in the Levant when Alexander the Great conquers the Middle East in 333 B. C. The new presentation of the sources found herein in will hopefully clarify several points in the history of Byblos during the first millennium B. C

Full textAbstract:
The European red fox (Vulpes vulpes L.) is a well known predator of native species and domestic stock, and is recognised as one of Australia’s most devastating vertebrate pests. Current fox management relies heavily on poisoning using baits impregnated with sodium monofluoroacetate (1080). This reliance on 1080 is likely to continue given the lack of viable alternatives for controlling foxes, so that, in the meanwhile, it is important to improve the efficiency of the current techniques. Factors affecting the susceptibility of individual foxes to bait include their ability to locate it, as well as the bait’s palatability and toxicity. The economic costs associated with using different bait types, the pattern and density of their distribution will also affect the efficiency of control programs. It is essential to examine and refine all such issues to ensure efficient use of the 1080 baiting technique. This thesis focuses generally on problems associated with management of the fox in eastern Australia. More specifically, I investigate the factors affecting the efficiency of fox baiting practices on the central tablelands of New South Wales. The study was conducted largely on agricultural lands near the town of Molong (33010’ 37”S, 148087’15”E) on the central tablelands of New South Wales. This area was chosen as it is broadly representative, in terms of land use, of a large region of eastern Australia. The highly modified, predominantly agricultural landscapes near Molong are well suited to foxes, and conflict with the predominantly pastoral community means that fox management is widely undertaken. I determined the persistence of 1080 in two commonly used bait types, Foxoff® and chicken wingettes, under different climatic and rainfall conditions. The rate of 1080 degradation did not change significantly between the central tablelands and the relatively hotter and drier western slopes. Foxoff® baits remained lethal for longer than wingettes under all conditions, although their rate of degradation generally increased with increasing rainfall. I confirmed the presence of defluorinating micro-organisms in thesoils of eastern Australia for the first time, and suggest that, following removal from the bait, 1080 would not persist in the environment for long. Bait should be attractive and highly palatable to ensure that the target species will find and consume it upon discovery. Caching, where discovered food is removed but not immediately consumed, may potentially reduce the efficacy and cost-effectiveness of baiting campaigns. I quantified the caching of chicken wingette, day-old chick and Foxoff® baits by inserting transmitters into bait material and assessing whether it was eaten or cached following removal. The intensity of caching did not change significantly between seasons. Type of bait had the largest influence on caching intensity, with a greater percentage of non-toxic Foxoff® baits (66.9%) being cached than either wingettes (5.7%) or day-old chicks (4.5%). The percentage of toxic (1080) baits cached was even greater, suggesting that 1080 bait may be less palatable, and detectable to foxes. I also investigated the use of conditioned taste aversion to reduce multiple bait uptake by foxes. Levamisole, an illness-inducing chemical, was added to bait and the fate of removed bait was again monitored via radio-telemetry. Following consumption of a levamisole-treated bait, foxes avoided eating treated baits but consumed untreated baits. I concluded that a reduction in bait consumption was achieved through learned aversion to levamisole rather than via conditioned taste aversion to baits. Adding levamisole to baits, especially non-toxic bait such as rabies vaccines, could potentially be used to reduce bait monopolisation by individual foxes. Fox density and den site preferences were assessed by investigating the distribution and density of fox natal dens on one property (9.6 km2) over three consecutive years. A total of 9 natal dens were located in 2000 and 2001, declining to 6 in 2002. No preference was shown for den sites on the basis of habitat, slope or aspect, but more dens were located under, or adjacent to cover. Assuming that each natal den represents a breeding pair and that the population sex ratio did not differ from parity (1:1), the site contained a prebreeding density of 1.9 foxes/km2 in 2000 and 2001, and 1.25 foxes/km2 in 2002. Given that the mean number of cubs is 4.0, the post-breeding density was estimated at 5.6 and 3.75 foxes/km2 in 2000/2001 and 2002, respectively. The results demonstrated that high densities of foxes occur on agricultural lands. The success and likely accuracy of the technique to monitor fox density suggests that it may be used to calibrate more efficient abundance estimates that will be essential for the strategic management of foxes in future. Pest animal management strategies are traditionally assessed for their effectiveness, with less consideration being given to the efficiency or cost of achieving the desired effect. I used cost-effectiveness analyses to compare between different baiting strategies based on the longevity, palatability and handling/replacement costs associated with each bait type. The results indicated that, when measured on a total cost-per-bait-consumed basis, wingettes and day-old chicks were the most cost-effective baits for campaigns of up to 4 weeks duration. This demonstrates the importance of including the longevity, and particularly the palatability of bait, when assessing cost-effectiveness. However, it is recognised that other factors, including the consistency of dosage and uptake by nontarget species, may be equally or more important in deciding the appropriate baiting strategy. The spatial and temporal application of fox baiting in the region overseen by the Molong Rural Lands Protection Board was examined between January 1998 and December 2002 as a case study to evaluate the apparent effectiveness of cooperative management practices. Most landholders (78.8%) did not bait for foxes during this period. Based on known dispersal distances, the effect of fox immigration into baited areas was determined. The results indicated that no areas baited for foxes were separated by a sufficient buffer distance (>9.58 km) from unbaited areas to be protected from fox immigration. This suggests that, at current levels of coordination, the effectiveness of most baiting operations in eastern Australia is compromised over the long term by fox immigration. However, it is recognised that short-term reductions in fox density may sometimes be all that are required to reduce predation to acceptable levels, especially for seasonally-susceptible prey. Ultimately, the cost-effectiveness of control should be evaluated in terms of the response of the prey rather than that of the predator. This study has highlighted deficiencies in current ‘best-practice’ baiting techniques. Specific recommendations for current baiting practices, in addition to future research, are also given. In brief, these include minimising free-feed baiting, increasing the minimum distance between bait stations, and, where possible, presenting the most palatable bait. Continued research into conditioned taste aversion, aerial baiting, and techniques to reduce caching are recommended as potential techniques to improve the efficiency of baiting practices.

This thesis extends and formalizes the energy signature method developed by Wei et al. (1998) for the rapid calibration of cooling and heating energy consumption simulations for commercial buildings. This method is based on the use of "calibration signatures" which characterize the difference between measured and simulated performance.
By creating a library of shapes for certain known errors, clues can be provided to the analyst to use in identifying what simulation input errors may be causing the discrepancies. These are referred to as "characteristic signatures". In this thesis, sets of characteristic signatures are produced for the climates typified by Pasadena, Sacramento and Oakland, California for each of the four major system types: single-duct variable-air-volume, single-duct constant-volume, dual-duct variable-air-volume and dual-duct constant-volume.
A detailed step-by-step description is given for the proposed methodology, and two examples and a real-world case study serve to illustrate the use of the signature method.

A web crawler provides an automated way to discover web events ? creation, deletion, or updates of web pages. Competition among web crawlers results in redundant crawling, wasted resources, and less-than-timely discovery of such events. This thesis presents a cooperative sharing crawler algorithm and sharing protocol. Without resorting to altruistic practices, competing (yet cooperative) web crawlers can mutually share discovered web events with one another to maintain a more accurate representation of the web than is currently achieved by traditional polling crawlers. The choice to share or merge is entirely up to an individual crawler: sharing is the act of allowing a crawler M to access another crawler's web-event data (call this crawler S), and merging occurs when crawler M requests web-event data from crawler S. Crawlers can choose to share with competing crawlers if it can help reduce contention between peers for resources associated with the act of crawling. Crawlers can choose to merge from competing peers if it helps them to maintain a more accurate representation of the web at less cost than directly polling web pages. Crawlers can control how often they choose to merge through the use of a parameter ρ, which dictates the percentage of time spent either polling or merging with a peer. Depending on certain conditions, pathological behaviour can arise if polling or merging is the only form of data collection. Simulations of communities of simple cooperating web crawlers successfully show that a combination of polling and merging (0 < ρ < 1) can allow an individual member of the cooperating community a higher degree of accuracy in their representation of the web as compared to a traditional polling crawler. Furthermore, if web crawlers are allowed to evaluate their own performance, they can dynamically switch between periods of polling and merging to still perform better than traditional crawlers. The mutual performance gain increases as more crawlers are added to the community.

Pyridazines are heterocyclic compounds with an N-N bond in their ring structure. Heterocyclic aromatic compounds are of great interest as a result of their novel properties and commercial applications. Our current research is focused on the potential role of pyridazines in next generation electronic devices that utilize organics as the semiconducting material. The synthesis of 5, 6-fused ring pyridazines beginning from fulvenes (Scheme 1) is described herein. These fused heterocycles will serve as synthetic models and building blocks for potential organic or organometallic conducting polymers.
Our goal was to modify the route of Snyder et al. previously reported for the direct synthesis of pyridazine 2. This required improved synthesis of fulvene 1 and higher yields of 5. Additionally, a thorough analysis of the x-ray data was obtained to better understand the 3D aspects of this compound (pyridazine 2).This route was quite general and features an efficient and convenient synthesis.
Single crystal X-ray analysis confirms the molecular structure of pyridazine 2. Full synthesis and characterization of newly formed pyridazine 2 and Fulvene 1 are reported.

The worldwide AIDS epidemic is known to have had a profoundly negative social, economic and personal impact and has taken a heavy toll on existing health care systems, particularly in developing countries. South Africa is experiencing an HIV epidemic with enormous social and economic consequences. Lopinavir/ritonavir antiretroviral treatment has been accredited with having a significantly positive effect and is a key advance in controlling HIV morbidity and mortality. An indigenous South African medicinal plant, Sutherlandia frutescens, known for its anti-diabetic properties and immune-boosting effects, is used for treating HIV positive patients suffering from opportunistic infections. Despite the use of the medicinal plant extract as homeotherapeutic medication, there is little evidence of toxicity testing that identifies its potential for interaction with antiretroviral drugs. However, scientific data relating to the mechanism through which Sutherlandia frutescens acts on the immune system has not been comprehensively documented. The aim of this study was to investigate lopinavir/ritonavir induced metabolic abnormalities in rats and whether the introduction of a plant extract of Sutherlandia frutescens would counteract the side effects of ARV medication. The results indicated that the rodents did not become insulin resistant, however, biochemical analysis indicated that extended ARV drug treatment would have caused insulin resistance. Significant morphological changes were found in the livers, kidneys and pancreases of rats exposed to the lopinavir/ritonavir. Rats exposed to the Sutherlandia frutescens plant extract showed improved histopathology with minimal abnormalities.

Full textAbstract:
It has been 17 years since the Soviet Union broke up and its constituent countries gained their independence. In the beginning years the sovereignty was considered an indisputable priority, resulting in economic matters being put off. However, in the light of slow economic development in the area, it seemed to be imperative for these countries to pursue economic integration. Backed up by political will, several attempts had been made to establish various integration groupings, one of them being the Commonwealth of Independent States. The established organisation’s main aim was to assist countries in preserving the connecting links inherited from the former Soviet Union. Some of the countries in the region managed to achieve relatively high growth rates mainly due to their individual efforts. Unfortunately, so far, none out of a number of proposed integration projects has proven to be an effective and binding tool in the political and economic development of the region. This thesis aims to identify problems standing in the way of economic integration of the Commonwealth of Independent States. As of now, a free trade area – the initial form of economic integration – has not been established. Although trade ties between the member states function, the main export destination of these states is outside the Commonwealth. It is recommended that the initial steps in setting up a free trade area in this territory should begin with developing integration within regional associations, due to smaller numbers of participants and their common interests.

Full textAbstract:
Despite improvements in the diagnosis and therapy of medulloblastoma (MB), the most common malignant paediatric brain tumour, survival rates are still only 40-60% for high-risk patients, and surviving patients offer suffer life-long therapy-associated late effects. Improving the current clinical disease risk classification may provide opportunities to tailor therapy to disease-risk more accurately, aiming to improve survival whilst minimizing late effects. The overall aim of this study was to identify and validate clinicopathological and molecular markers of prognostic significance in a large cohort of cases derived from the PNET3 clinical trial, which could be used in improved disease stratification schemes. Initial investigations focussed on defects of chromosome 17, the most common chromosomal aberrations identified in MB, which have been associated with adverse outcome in some previous studies. During this initial study, methods for testing for regions of genetic loss in DNA samples extracted from routinely collected and stored pathology material were developed and validated. Using these methods, 17p loss was assessed in 284 cases overall, but did not show an association with poor prognosis. 17p loss was rare in patients <3 years at diagnosis (1/21 cases) compared to children aged >3 years (21/59, p=0.009), supporting the notion that infants with MB may represent a biologically distinct disease subgroup. During the course of this study, evidence of a microsatellite instability phenotype was also found in one case (1/29; 3.8%), suggesting a role for this phenomenon in a small subset of medulloblastomas. Previous studies have identified MBs with activation of the Wnt/Wg signalling pathway to be associated with a favourable outcome. Three independent molecular markers of Wnt/Wg activation in medulloblastoma (β-catenin nuclear localization, CTNNB1 mutation and chromosome 6 loss) have recently been identified, and were therefore assessed in the PNET3 cohort to examine their inter-relationships and relative prognostic utilities. β-catenin nuclear localization was detected in 34/207 (16.4%) cases, CTNNB1 mutation in 20/197 (10.1%), and chromosome 6 LOH in 20/190 (10.5%); all three markers were highly associated with each other (p=0.001). Univariate survival analysis showed significant associations between clinicopathological (gender, pathology, M stage and extent of tumour resection) and molecular variables (β-catenin nuclear localization and CTNNB1 mutation) with survival (all 'p' values <0.03) in the PNET3 cohort. Multivariate survival analysis and Cox proportional regression hazard analysis identified M stage, large cell / anaplastic pathology, gender and β-catenin nuclear staining to be significantly associated with prognosis (p<0.04), with hazard ratios of 1.924, 3.338, 0.57 and 0.215, respectively. Finally, combined models for disease risk prediction were constructed using the prognostically significant clinicopathological and molecular variables identified, including models to precisely classify the overall disease hazard for individual cases based on their clinical, pathological and molecular profile. In summary, Wnt/Wg pathway activation was associated with favourable outcome and can be most accurately identified using β-catenin nuclear staining. Combined models which incorporate Wnt/Wg status alongside other prognostically significant clinical and pathological indices validated in this study provide schemes for improved disease risk prediction in medulloblastoma, which should now be tested prospectively in large clinical trials.

Full textAbstract:
Nowadays all existing public key cryptosystems are classified into three categories relied on different mathematical foundations. The first one is based on the difficulty of factoring the product of two big prime numbers. The representatives are the RSA and the Rabin cryptosystems. The second one such as the ElGamal cryptosystem is based on the discrete logarithm problem. The last one is based on the NP-completeness of the knapsack problem. The first two categories survived crypto attacks, whereas the last one was broken and there has been no attempt to use such a cryptosystem. In order to save the last category, Kiriyama proposed a new public key cryptosystem based on the non-linear knapsack problem, which is an NP-complete problem. Due to the non-linear property of the non-linear knapsack problem, this system resists all known attacks to the linear knapsack problem. Based on his work, we extend our research in several ways. Firstly, we propose an encrypted secret sharing scheme. We improve the security of shares by our method over other existing secret sharing schemes. Simply speaking, in our scheme, it would be hard for outsiders to recover a secret even if somehow they could collect all shares, because each share is already encrypted when it is generated. Moreover, our scheme is efficient. Then we propose a multiple identities authentication scheme, developed on the basis of the non-linear knapsack scheme. It verifies the ownership of an entity's several identities in only one execution of our scheme. More importantly, it protects the privacy of the entities from outsiders. Furthermore, it can be used in resource-constrained devices due to low computational complexity. We implement the above schemes in the C language under the Linux system. The experimental results show the high efficiency of our schemes, due to low computational complexity of the non-linear knapsack problem, which works as the mathematical foundation of our research.

Full textAbstract:
In January 2013, the Japanese Government under Prime Minister Shinzo Abe and the Bank of Japan launched a package of monetary and fiscal stimulus along with promises of structural economic reform called Abenomics. This paper examines the preliminary effects of the Bank of Japan’s Quantitative and Qualitative Monetary Easing (QQE), which forms the monetary component of Abenomics. Given the weak economic response to QQE so far, the study predicts that QQE has failed to make a significant impact on its target macroeconomic variables of inflation and output. The results confirm this hypothesis as increases in the monetary base have an insignificant effect on the Consumer Price Index and have little effect in changing the trajectory of output. The results of QQE so far mirror those of the Federal Reserve’s quantitative easing programs, during which expansion of the monetary base in the aftermath of the 2008 financial crisis failed to significantly raise output given the size of the stimulus. Abenomics, however, continues to be implemented, making the results presented in this paper inconclusive.

Full textAbstract:
The application of personality assessment techniques for clinical and personnel decisions has
always been a major activity for psychologists all over the world. In South Africa personality
assessment tools are often used for purposes of selection, placement, determination of job
satisfaction and development. Psychological testing in South Africa was originally initiated
with white test-takers in mind, and currently none of the available personality questionnaires
used in South Africa have been found to provide a reliable and valid picture of personality for
all cultural (language) groups.
Since 1994 South Africa has had a new constitution and there are stronger demands for the
cultural appropriateness of psychological tests. In this study, the implicit perspectives of
personality of Sesotho-speaking South Africans are being determined in order to develop a
more culturally fair personality assessment tool for South Africans.
A qualitative research design was used with an interview as data-gathering instrument. A
Sesotho-speaking fieldworker was recruited to interview 120 Sesotho-speaking South
Africans from the Free State Province. The study population was purposely drawn from
different sections of the Sesotho-speaking population. A total of 4873 Sesotho-speaker
personality descriptors were obtained from the participants and then translated into English.
Content analysis was used to analyse, interpret and reduce these descriptors to a total of 94
personality characteristics, which highlights the most important perspectives of personality
for Sesotho-speaking individuals.
The personality characteristics were divided into seven categories, namely sociability,
interpersonal relatedness, emotionality, meanness, conscientiousness, dominance and other.
The majority of the characteristics are representative of communalism or the collective
consciousness in African communities. Sesotho-speaking persons are socially active and are
sympathetic, caring and tolerant towards others, they are willing to become involved in the
feelings, problems and welfare of others.
The findings of this study were compared to the Five Factor Model and evidence were found
for the extraversion, conscientiousness, neuroticism and agreeableness factors, but not for the
openness to experience factor. In comparison with the Chinese Personality Assessment
Inventory support were found for 17 of the 22 personality scales. Characteristics such as
admonitory, resourcefulness, religion, humour, fair, judgemental and discriminating can be
seen as characteristics indigenous to the Sesotho culture.
Limitations in the research are identified and recommendations for future research are made.Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2006.

Full textAbstract:
Because of its geographical location, the Arctic environment is considered as pristine. However, expanding industrial activities in the Arctic require assessment of the toxicity of chemicals at low temperature. Biomarkers defined as "biological responses to a chemical or chemicals that give a measure of exposure or toxic effect" were shown to be relevant to measure in situ impact of oil discharges. Most biomarker studies have been performed with temperate organisms. The Arctic is characterised by low stable temperature, strong seasonality in light, resulting in a short primary production in Spring. Therefore, indigenous organisms have developed specific adaptations to live with a hmited food supply in water near freezing point. Conversely, physical properties of petroleum hydrocarbons are affected by low temperature (i.e. reduced solubility). Consequently, the biological adaptation of cold-water organisms together with the altered oil behaviour, may affect typical biomarker responses. Because oil compounds are strongly prooxidant, the research strategy of this work was based on oxidative stress. The antioxidant defences were investigated by measuring the total oxyradical scavenging capacity (TOSC). The impact of reactive oxygen species was investigated by measuring the stability of the cell membranes. Finally, the physiology of the organisms was considered by looking at heart and respiration rates. Invertebrates were selected for study owing to their abundance in the polar ecosystem. They were sampled using dredges and Scuba diving from the research vessel Jan Mayen (University of Tromso) in May and August 1999, and during May and September 2000 in the l^ords of Svalbard and in Antarctica as well in January 2000. In the Arctic, two bivalves, Mya tnincata and Chlamys islandicus, and two crustaceans, Hyas araneus and Sclerocrangon boreas were selected. In this work, the ecophysiology of Arctic and Antarctic marine invertebrates was investigated and compared to temperate organisms. Polar marine invertebrates are characterised by low respiration and heart rates and a high TOSC. The elevated level of antioxidant defences is thought to reflect the oxidative pressure of the polar marine ecosystem; however, it suggested that a high TOSC may help to protect biomolecules from oxidative damage as repair mechanisms are limited due to the lack of food for 9 months. Organisms were exposed to poly aromatic hydrocarbons either dissolved, dispersed injected or via sediment. TOSC, cell membrane stabiHty and heart rate were valid biomarkers to monitor the impact of poly aromatic hydrocarbons in Arctic marine organisms. The biomarker responses obtained in this study provide essential background information for monitoring the potential impact of oil and gas activities in the Arctic.

O sistema é composto por um conjunto de 23 indicadores que abrangem os balanços econômico, social e ambiental. São apresentadas características da sustentabilidade relacionadas ao agronegócio, mais precisamente na produção leiteira, destacando que apenas soluções que considerem o crescimento econômico com impactos positivos em termos sociais e ambientais, merecem a denominação de desenvolvimento sustentável. O sistema de indicadores para avaliação da sustentabilidade de propriedades produtoras de leite aqui proposto, com o objetivo de realizar um diagnóstico da perspectiva de sustentabilidade, mostrou-se um método abrangente e suficiente para aplicação em campo para uma primeira avaliação do impacto de atividades agropecuárias. Com a realização deste um diagnóstico, utilizando um conjunto de indicadores de fácil compreensão e um sistema de simples operação, os produtores poderão visualizar melhor a contribuição de suas práticas ao sistema de produção e façam os seus próprios julgamentos, procurando melhorias em busca da sustentabilidade das atividades realizadas no estabelecimento.
That study aimed to analyze a sustainable rural development approach, putting forward a construction of a system of indicators for assessing the sustainability of dairy small farms. The system has been consisted by a set of 23 indicators covering both the economic, such as the social and environmental balances. There are shown agribusiness characteristics concerning sustainability, notedly at milk production, highlighting that only solutions which consider economic growth with positive impact on social and environmental terms have deserved the denomination of sustainable development. The system of indicators for assessing the sustainability of dairy small farms here proposed, in order to make a diagnosis of the sustainability perspective, proved to be a comprehensive and sufficient method for field application for a first assessment of the impact of agricultural activities. By performing this diagnosis, using a set of understandable indicators and a simple operating system, producers will be able to see better the contribution of theirs practices in the production system and make their own judgments, searching for improvements in the sustainability of the activities carried out at the rural establishment.

Thesis (PhD (Chemistry and Polymer Science))--University of Stellenbosch, 2009.Due to numerous accidents involving munitions, recent interest has focused on the development and use of insensitive munitions (IM). Polymeric materials are used in insensitive munitions as binders or plasticizers. Most of the polymeric binders used are based on polycondensation reaction via using urethane linkages. The main aim of this study was the synthesis and characterization of selected energetic thermoplastic elastomers binder based on utilizing controlled free radical polymerization. This was achieved by using hydroxyl terminated poly (epichlorohydrin) (PECH-diol) and hydroxyl terminated glycidyl azide polymer (GAP-diol) as starting materials, and the subsequent synthesis of different macroinitiators. These macro-initiators were used to polymerize methyl methacrylate (MMA) to obtain thermoplastic elastomers. PECH-diol was prepared by cationic ring-opening polymerization (CROP) based on using borontrifluoride etherate (BF3-etherate) as catalyst and a low molecular weight diol as initiator. GAP-diol was synthesized by the reaction of PECH-diol with sodium azide in organic solvent.. Poly(epichlorohydrin-methyl methacrylate) (PECH-PMMA) and poly(glycidyl azidemethyl methacrylate) (GAP-PMMA) block copolymers were prepared by free radical polymerization of MMA monomer in presence of PECH and GAP macro-azoinitiator (MAI). The MAIs were prepared by the polycondensation reaction of hydroxyl terminated groups of elastomer with 4,4' azobis (4-cyanopentanoyl chloride) (ACPC). The phase behavior of blends of amorphous PMMA/PECH-diol and PMMA/GAP-diol was also investigated. Poly(epichlorohydrin-methyl methacrylate) (PECH-PMMA) and poly(glycidyl azidemethyl methacrylate) (GAP-PMMA) graft copolymers were synthesized by photopolymerization of MMA in presence of PECH and GAP with pendant N,Ndiethyldithiocarbamate groups as macro-photoiniferters. . Photopolymerization of MMA proceeded in a controlled fashion. A macro RAFT agent, based on the reaction of PECH with pendent dithiobenzoate was prepared. The macro-RAFT agent was used in the controlled thermal bulk polymerization of methyl methacrylate. Finally, living/controlled radical polymerization of MMA with four different photoiniferters, namely benzyl diethyl dithiocarbamate (BDC), 2-(N,N-diethyldithiocarbamyl) propionic acid (PDC), 2-(N,Ndiethyldithiocarbamyl) isobutyric acid (DTCA), and diethyl dithiocarbamateepichlorohydrin was achieved.

Full textAbstract:
This dissertation consists of two essays on predictability of asset prices. "Benchmarking problems and long horizon abnormal returns" and, "Low R-square in the cross section of expected returns". Long run abnormal returns following Initial Public Offerings (IPOs), Seasoned Equity Offers (SEO) and other firm level events are well documented in the finance literature. These findings are difficult to reconcile in an efficient markets world. I examine the seriousness of potential benchmarking errors on the measurement of abnormal returns. I find that the simpler, more parsimonious models perform better in practice and finds that excess performance is not predictable regardless of the APM. Thus, the long run underperformance following SEOs found in the literature is consistent with market efficiency because excess performance itself is not predictable. In the other essay, "Low R-square in the cross section of expected returns", I examine the “low R-square†phenomenon observed in the literature. CAPM predicts exact linear relationship between return and betas (SML). This means that estimated time series betas for firms should be related with firms' future returns. However, the estimated betas have almost no relationship with future returns. The cross-sectional R2 are surprising low (3% average) while time series R2 are higher (around 30 % average). He develops a simple asset pricing model that explains this phenomenon. Even in a perfect world where there are no errors in the benchmark measurement or estimation of the price of market risk the difference in R-squares can be quite large due to the difference in variance between the "market" and average returns. I document that market variance exceeds the variance of average returns, with few exceptions, for the last 74 years.

In an era of tremendous growth in online journalism, the proximity press seems to be increasingly gaining importance. In order to understand the concept of local online journalism, it becomes relevant to decode these two concepts that rotate around the journalism: on the one hand, the emergence of online, and, on the other hand, the importance of the proximity press. It was with this mission that the main concepts were conceptualized around the two central themes of work, first as individual elements and, subsequently, to the overview. In other words, the study aimed to act as a guiding principle: started with the paradigm shift in communication, following the online news and their peculiarities, through proximity journalism and some of its aspects, including the specific case of Portugal, ending with a possible definition of local online journalism online In this sense, the research is particularly important, by submitting an example of a Portuguese regional site: the online edition of the Jornal da Mealhada. This site has been functionally examined, in order to estimate the impact of new technologies of communication in local online media, more specifically, the use of the add-values of the online journalism in local media. The study showed that despite the use of some of the gains offered by digital technologies, proximity information still has a long way to go in order to increase the quality of the contents.

O presente relatório inicia-se com uma descrição dos espaços físicos e dos recursos humanos da farmácia, respetivas funções e responsabilidades. Em seguida abordam-se aspetos relacionados com a informação e documentação científica necessária à atividade farmacêutica, aprovisionamento e armazenamento de medicamentos e outros produtos de saúde e legislação que regula toda a prática farmacêutica em Farmácia Comunitária. Seguem-se os tópicos de dispensa de medicamentos, automedicação, aconselhamento e dispensa de produtos de saúde e preparação de medicamentos, tendo sempre em conta a vertente da interação do farmacêutico com o utente e destes com o medicamento. Por fim, abordam-se alguns aspetos relacionados com os vários cuidados de saúde prestados na farmácia e descreve-se a aplicação da contabilidade e da gestão à Farmácia Comunitária.
O Capítulo 2 refere-se à componente de investigação. Durante o último século, a profissão do farmacêutico comunitário experienciou um crescimento significativo e uma evolução desde a farmácia tradicional à farmácia mais cognitiva e focada no utente. Para que esta evolução continue e o serviço da Farmácia Comunitária seja aprimorado, é necessário conhecer os utentes, as suas necessidades e expetativas, as suas opiniões e preferências. Assim, o objetivo deste estudo foi avaliar a satisfação dos utentes com os serviços de Farmácia Comunitária, no concelho da Covilhã, e identificar os fatores e o modo como influenciam essa satisfação. Para isso, foi utilizado um questionário, composto por 38 itens destinados a avaliar a satisfação dos utentes quer com a área física e instalações da farmácia quer com os profissionais e serviços farmacêuticos que lhes foram prestados. Simultaneamente, o questionário apresentava itens que permitiam fazer a caraterização sociodemográfica da amostra obtida. A aplicação foi feita pela equipa da farmácia, após um atendimento. Concluiu-se que a satisfação global dos utentes com a farmácia, profissionais da farmácia e serviços prestados é elevada e que os principais fatores que a influenciam são o género, a duração da relação com a farmácia e o tempo de espera até ser atendido.Chapter 1 refers to the component of training in Community Pharmacy. Discusses the activities performed during the stage in Pharmacy Silva Tavares, lasting 400 hours, under the guidance of Paula Oliveira. This training created the opportunity for contact with the most diverse areas of the pharmacist’s activity in Community Pharmacy. This report begins with a description of the physical and human resources of pharmacy, respective roles and responsibilities. Then, is made an approach to aspects related to scientific information and documentation necessary for pharmaceuticals, supply and storage of medicines and other health products and legislation that regulates the pharmaceutical practice in Community Pharmacy. Here are the topics of dispensing medications, self-medication, counseling and dismissal of health products and preparation of medicines, taking into account the aspect of interaction with the patient and with the drug. Finally, is made an approach to some aspects related to health care services provided at the pharmacy and is described the application of accounting and management on Community Pharmacy. Chapter 2 refers to the component of research. During the last century, the pharmacy community profession has experienced significant growth and evolution from a traditional pharmacy to a more cognitive pharmacy and focused on the user. For this trend to continue and so that their services are improved, it is necessary to know the users, their needs and expectations, their opinions and preferences. The objective of this study was to evaluate user satisfaction with the services of Community Pharmacy, in the county of Covilhã, and identify the factors and how they influence customer satisfaction. For this, we used a questionnaire comprising 38 items designed to measure customer satisfaction with both the physical space and facilities of pharmacy, pharmacy professionals and pharmacy services provided to them. Simultaneously, the questionnaire had items that allow the sociodemographic characteristics of the sample to be obtained. The application was made by the pharmacy team, after a service. It was concluded that the overall satisfaction of users with the pharmacy, pharmacy professionals and services is high and that the main factors that influence it are the gender, the duration of the relationship with the pharmacy and waiting time to be served.

Este estudo teve por objetivo avaliar, in vitro, a resistência de união à microtração (RUM) mediata (12 meses) dos sistemas adesivos Adper Scotchbond SE / 3M/ESPE (Adper SE) e Adper Scotchbond Multi-Uso / 3M/ESPE (Adper SMP) à superfície dentinária sadia, tratada ou não com uma solução ácida experimental inibidora de metaloproteinases (MMPs), bem como o padrão predominante de falha por fractografia; e avaliar, in vitro, a inibição da atividade gelatinolítica por uma solução ácida experimental para condicionamento de superfície dentinária contendo tetraciclina em comparação com uma solução experimental contendo tetraciclina. Para avaliação da RUM mediata, nos grupos Adper SE Controle e Adper SMP Controle, o sistema adesivo foi aplicado de acordo com as instruções do fabricante. No grupo Adper SE Experimental foi aplicada a solução experimental previamente ao sistema adesivo, e no grupo Adper SMP Experimental, o condicionamento com ácido fosfórico a 37% foi substituído pela aplicação da solução experimental. Após a aplicação dos sistemas adesivos, os dentes foram preparados para o teste de RUM, e os palitos obtidos foram armazenados em estufa a 37oC. Após 12 meses, foi realizado o teste RUM e os palitos foram avaliados em MEV. Para avaliação da atividade enzimática, amostras salivares foram coletadas de doadores saudáveis, centrifugadas e o sobrenadante foi usado através da técnica zimográfica. Esta técnica baseou-se no uso da eletroforese, no qual um substrato proteico (gelatina) foi co-polimerizado com acrilamida. As enzimas foram separadas sob condições não redutoras, renaturadas e então incubadas em tampão adequado, baseando-se na associação entre digestão do substrato e verificação do peso molecular das proteases. Para quantificar a inibição relativa pelas duas soluções foi usado o programa Image J (NIH, Bethesda, MD, USA) e comparadas com o controle. Em relação à RUM mediata, de acordo com o teste de Tukey (α=0.05), não houve diferença entre os grupos controle e experimental para cada sistema adesivo. O padrão predominante de falha para o sistema adesivo Adper SE foi coesiva em resina composta enquanto que para o Adper SMP foi coesiva em camada híbrida. Na análise zimográfica, as enzimas foram caracterizadas como metaloproteinases da matriz, pois a sua expressão foi inibida pelo EDTA (um conhecido inibidor de MMPs), enquanto o NEM (um inibidor de proteases serinas) não teve nenhum efeito sobre a atividade enzimática. A MMP identificada no estudo, foi caracterizada como MMP-2, apresentando um peso molecular de 62KDa. A solução ácida experimental apresentou um percentual de inibição da atividade gelatinolítica de 93.66% (concentração de 0.05%) e de 58.58% (concentração de 0.01%), enquanto que a solução experimental teve um percentual de inibição de 31.28% e 6.83%, respectivamente. Com base nos resultados encontrados é possível concluir que após 12 meses de armazenagem, o sistema adesivo Adper SE mostrou desempenho superior ao Adper SMP no teste de RUM, parecendo também ser mais efetivo na manutenção da integridade da interface adesiva, sob análise fractográfica; e que a solução ácida experimental condicionadora de superfície dentinária foi capaz de inibir quase completamente a atividade enzimática da MMP-2, de uma maneira dose dependente.
This study aimed to evaluate, in vitro, the mediate microtensile bond strength- μTBS (12 months) of adhesive systems Adper Scotchbond SE / 3M/ESPE (Adper SE) and Adper Scotchbond Multi-Purpose / 3M/ESPE (Adper SMP) to sound dentin surface, treated or not with an experimental acid solution inhibitor of metalloproteinases (MMPs), as well as the predominant pattern of failure by fractography; and evaluate, in vitro, the inhibition of gelatinolytic activity by an experimental acid solution for dentin surface etching containing tetracycline compared with an experimental solution containing tetracycline. For mediate μTBS evaluation, in Adper SE Control and Adper SMP Control groups, the adhesive system was applied according to the manufacturer's instructions. In Adper SE Experimental group was applied the experimental solution prior to the adhesive system, and in the Adper Experimental SMP group, the etching with 37% phosphoric acid was replaced by applying the experimental solution. After applying the adhesive systems, the teeth were prepared for μTBS test, and the sticks were stored in an oven at 37°C. After 12 months μTBS test was realized and the sticks were evaluated by SEM. For enzymatic activity evaluation, saliva samples were collected from healthy donors, centrifuged and the supernatant was used by technique of zymography. This technique was based on the use of electrophoresis, in which a protein substrate (gelatin) was co-polymerized with acrylamide. The enzymes were separated under non-reducing conditions, renatured and then incubated in suitable buffer, based on the association between the substrate digestion and verification of the molecular weight of proteases. To quantify the relative inhibition by the two solutions was used the Image J software (NIH, Bethesda, MD, USA) and compared with the control. For mediate μTBS evaluation, according to the Tukey test (α = 0.05), no difference between the control and experimental groups was found for each adhesive system. The predominant pattern of failure for the system Adper SE was cohesive in composite while for Adper SMP was cohesive in hybrid layer. In the enzymatic activity evaluation, the enzymes were characterized as matrix metalloproteinases, because its expression was inhibited by EDTA (a known inhibitor of MMPs), while NEM (an inhibitor of serine proteases) had no effect on enzymatic activity. The MMP identified in the study, was characterized as MMP-2, with a molecular weight of 62KDa. The experimental acid solution presented an inhibition of the gelatinolytic activity of 93.66% (concentration 0.05%) and 58.58% (0.01% concentration), while the experimental solution had a percentage inhibition of 31.28% and 6.83%, respectively. Based on these results we conclude that after 12 months of storage, the adhesive system Adper SE showed better performance that Adper SMP in the microtensile bond strength test, also seeming to be more effective in maintaining the integrity of the adhesive interface, under fractographic analysis; and that the experimental acid solution for dentin surface etching was capable of almost completely inhibits the enzymatic activity of MMP-2 in a dose dependent manner.

October 2013This report presents the design and development of a five cell multicell inverter for driving a piezoelectric load. The multicell inverter was chosen for this application as it became evident that it would be more suitable for driving piezoelectric transducers due to its high apparent switching frequency. The multicell inverter was designed using DirectFET’s as this type of FET has a high current switching ability in a very small package. A positive and negative bootstrap power supply was incorporated in the design to reduce the number of supplies to power the gate drive circuits of the multicell inverter. Three compensation networks were designed and constructed to investigate which one would transfer the most energy to the piezoelectric transducer. It was also important to investigate whether these compensation networks were able to reduce the harmonic content produced by the multicell inverter. This is necessary in order to excite the transducer correctly. It was found that the Q-Matching compensation network reduced the harmonic content applied to the load the most. Experiments were also conducted to determine if the advantage of the apparent frequency of the multicell inverter would mean that the piezoelectric load could be driven directly with the multicell inverter without any damage to the transducer. It was however required to increase the applied apparent power to the transducer to compensate for the reactive component of the load in order to melt the plastic which was used as the load to the transducer. Experiments were conducted to determine if the charge on the cell capacitors of the multicell inverter would stay balanced while driving a non linear load such as a piezoelectric transducer. The results showed that the voltages stayed balanced when driving the piezoelectric transducer.

Full textAbstract:
Twenty Four samples of xenoliths and country rocks from the 1961 lava flow of Calbuco volcano have been studied. Fourteen samples have been analyzed for major elements and P, Ni, Ba, Cr, V, Zr, Sc, Y, and Sr. Five of these samples were further analyzed for Sm, Nd, Sr, and Pb isotope ratios. Seventeen samples were studied under the microscope and three samples were analyzed by microprobe for their pyroxene compositions.
Based on petrographic studies xenoliths were divided into three groups. Fine grained xenoliths (groups I and II) probably formed from metamorphosed MORB-like basalts, whereas coarse grained xenoliths (group III) were apparently derived from cumulate minerals that crystallized from the Calbuco magma. The fine grained xenoliths were probably entrained in magma at intermediate levels of the crust, near the stability limit of amphibole to form pyroxene and plagioclase. In the coarse grained xenoliths amphibole that formed at depth dehydrated as the xenoliths were brought to the surface. The country rocks are apparently unrelated to the xenoliths.

Lin, Abraham. "Perceived Efficacy in Patient-Physician Interactions among Older Adults with Atrial Fibrillation." eScholarship@UMMS, 2020. https://escholarship.umassmed.edu/gsbs_diss/1080.
Full textAbstract:
Background: Management of atrial fibrillation (AF) is complex and requires active patient engagement in shared decision making to achieve better clinical outcomes, greater medication adherence, and increased treatment satisfaction. Efficacy in patient-physician interactions is a critical component of patient engagement, but factors associated with efficacy in older AF patients have not been well-characterized.
Methods: We performed a cross-sectional analysis of baseline data from the ongoing Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF) study, a cohort study of older adults (age ≥ 65) with non-valvular AF and CHA2DS2-VASc score ≥ 2. Participants were classified according to their Perceived Efficacy in Patient-Physician Interactions (PEPPI-5) score (lower: 0-44; higher: 45-50). Logistic regression analysis was used to identify sociodemographic, clinical (AF type, AF treatment, medical comorbidities), and geriatric (cognitive impairment, sensory impairment, frailty, independent functioning) factors associated with lower reported efficacy.
Results: Participants (n = 1209; 49% female) had a mean age of 75. A majority (66%) reported higher efficacy in their interactions with physicians. Lower efficacy was associated with persistent AF (adjusted odds ratio [aOR] = 1.52; 95% confidence interval [CI] = 1.13-2.04) and with symptoms of depression (aOR = 1.67; CI = 1.20-2.33) or anxiety (aOR = 1.40; CI = 1.01-1.94). Decreased odds of lower efficacy were observed in participants with chronic kidney disease (aOR = 0.68; CI = 0.50-0.92) and those classified as pre-frail compared to those classified as not frail (aOR = 0.71; CI = 0.53-0.95).
Conclusion: Older patients with persistent AF or symptoms of depression or anxiety have decreased efficacy in patient-physician interactions. These individuals merit greater attention from physicians when engaged in shared decision making.

Full textAbstract:
Cette thèse présente l'étude et le développement d'un outil de simulation numérique efficace pour la modélisation de l'interaction plasma/micro-ondes, à partir d'un solveur électromagnétique basé sur une approximation Galerkin Discontinue (GD). Le travail est organisé en deux parties principales. Tout d'abord, nous développons un modèle Particle-In-Cell (PIC) approprié au schéma GD. Pour cela, d'une part, nous proposons un modèle de correction hyperbolique pour la prise en compte de la loi de conservation de la charge et, d'autre part, nous intégrons des modèles physiques propres au plasma tels que les sources micro-ondes de forte puissance, les surfaces d'émission de particules et les faisceaux d'électrons. Ensuite, nous nous orientons vers la recherche de performances optimales pour le couplage Maxwell-Vlasov afin d'augmenter l'efficacité et la taille des applications à traiter. Cette recherche conduit à l'étude d'une hybridation non conforme de méthodes pour résoudre le problème Maxwell-Vlasov. Dans un premier temps, nous travaillons sur une méthode hybride entre différents schémas numériques pour la résolution d'un problème Maxwell 1D sur des maillages non conformes. Dans un second temps, nous nous intéressons au cas d'un problème 2D en mode TE, dans l'optique d'introduire un modèle PIC. Finalement, nous réalisons une hybridation FDTD/FDTD sur deux maillages non coïncidents pour les équations Maxwell-Vlasov 2DThis thesis presents the study and the development of an efficient numerical simulation's tool for the modeling of plasma/microwave interaction in an electromagnetic software based upon a Discontinuous Galerkin (DG) scheme. This work is organized following two main steps. First, we develop a Particle-In-Cell (PIC) model appropriate for DG scheme. For this, on the one hand, we propose a hyperbolic corrector method to take into account the charge conservation law and, on the other hand, we integrate physical plasma models such as high power microwave sources, emission particles surfaces and electrons beams. Then, we propose also optimal performances for the coupling of Maxwell-Vlasov equations in order to increase the efficiency and the size of the applications to treat. This leads to study a non conformal hybridization of methods to solve the Maxwell-Vlasov problem. In the first time, we work on a hybrid method between different numerical schemes to solve a 1D Maxwell problem on non conformal meshes. In the second time, we interest in a 2D TE Maxwell problem, in order to introduce a PIC model. Finally, we realise a FDTD/FDTD hybridization on two non coincident meshes for the 2D Maxwell-Vlasov system

Mestrado em Activação do Desenvolvimento PsicológicoO presente estudo considera que no ensino da matemática, no 1.º Ciclo do Ensino Básico, o Estilo do Adulto – empenho do Professor – é uma dimensão determinante na qualidade educativa, repercutindo-se nos níveis de implicação dos alunos e resultados escolares consequentes. Participam, neste estudo, oito professoras e respectivos alunos de idades compreendidas entre os seis e os dez anos, de um Agrupamento de Escolas do concelho de Oliveira de Azeméis. Junto desta amostra, aquando do ensino da matemática em sala de aula, utilizou-se uma grelha de observação do estilo de interacção adulta, através da utilização da versão adaptada do instrumento Adult Style Observation Schedule - ASOS (Laevers, Bertram & Pascal, 1995), que identifica as dimensões Sensibilidade, Estimulação e Autonomia, e a Escala de Envolvimento da Criança (The Leuven Involvement Scale for Young Children – LIS-YC de Ferre Laevers, 1994). Os dados obtidos indicam que os resultados escolares não se relacionam, apenas, com os níveis de Implicação e com o Estilo do Adulto, mas com outros factores, como o contexto familiar dos alunos, características individuais e a ecologia escolar. ABSTRACT: This study considers how in the teaching of Mathematics in the first four years of primary school, the adult’s style – the teacher’s commitment - is a crucial dimension in the quality of education, impacting upon the level of involvement of students and school performance activity. Eight teachers and their students aged between six and ten years affiliated to a grouping of schools in the municipality of Oliveira de Azeméis participate in this study. In this sample, we used a grid of observation adult style of interaction through the use of the adapted version of the instrument Adult Style Observation Schedule - ASOS (Laevers, Bertram & Pascal, 1995) teaching of mathematics in the classroom. This grid identifies the dimensions Sensitivity, Stimulation and Autonomy, and the Scale of Involvement of Children (The Leuven Involvement Scale for Young Children - LIS-YC of Laevers Ferre, 1994). The data indicate that school results are not related only with the level of implication and the style of adult, but with other factors such as the family background of the students, individual characteristics and school ecology.
