Khan, Raja S. R. "TERA for Rotating Equipment Selection." Thesis, Cranfield University, 2012. http://dspace.lib.cranfield.ac.uk/handle/1826/9338.
Full textAbstract:
This thesis looks at creating a multidisciplinary simulation tool for rotating plant equipment
selection, specifically gas turbines, for the liquefaction of natural gas (LNG). This is a
collaborative project between Shell Global Solutions and Cranfield University in the UK. The
TERA LNG tool uses a Techno-economic, Environmental and Risk Analysis (TERA)
approach in order to satisfy the multidisciplinary nature of the investigation. The benefits of
the tool are to act as an aid to selection, operations and maintenance planning and it also acts
as a sensitivity tool for assessing the impact of changes in performance, environmental and
financial parameters to the overall economic impact of technology selection. The aim is to not
only select technology on the basis of techno-economics but also on the basis of risk analysis.
The LNG TERA tool is composed of a number of modules starting with the performance
simulation which calculates the thermodynamic conditions in the core of the engine. Next, life
estimates of the hot gas path components are made using a mixture of parametric and
probabilistic lifing models for the turbine first stage blades, coatings, and combustor liner.
This allows for a risk analysis to be conducted before maintenance and economics issues are
dealt with. In parallel, emissions estimations are made based on empirical correlations. The
modelling exemplifies a methodology which is uniquely applied to this application and there
are no studies previous to this which look at so many aspects before making conclusions on
plant machinery selection.
Comparisons have been done between industrial frame engines based on the General Electric
Frame 9E (130 MW) and Frame 7EA (87 MW) engines as well as more complex cycles
involving aero-derivation and inter-cooling such as the LM 6000 (42 MW) and LMS 100 (100
MW). Work has also been carried out to integrate the tool to Shell based systems in order to
utilise the database of information on failure and maintenance of machinery as well as its
performance.
The results of the integrated TERA show a clear favour for the aero-derivative engines and
the main benefit is the fuel saving, though the life of the hot gas path components is
deteriorated much faster. The risk results show that the industrial frame engines have a wider
variation in expected life compared to aero-derivatives, though the industrial frames have
longer component lives. In the context of maintenance and economics, the aero-derivative engines are better suited to LNG applications. The modular change out design of the aero-
derivatives also meant that time to repair was lower, thus reducing lost production.
Application of the LNG TERA tool was extended to power generation whereby a series of 6
engines were simulated. The changes required to the modelling were minimal and it shows
the flexibility of the TERA philosophy. This study was carried out assuming a given ratio of
load split between the engines and hence is sensitive to the way an operator demands power
of the engine as opposed to LNG application where the operator tries to drive the engine as
hard as possible to get the most production out of the train.
The study was limited in the modes of failure which were investigated, a major further work
would be to extend the methodology to more components and incorporate fatigue failure.
Further, the blade creep and probabilistic coating models were very sensitive to changes in
their respective control parameters such as coating thickness allowances and firing
temperature.
The contribution to the project from the MBA is the statistical techniques used to conduct the
risk analysis and data handling as well as financial management techniques such as the Net
Present Value (NPV) methodology for project evaluations.

Kang, U. "Mining Tera-Scale Graphs: Theory, Engineering and Discoveries." Research Showcase @ CMU, 2012. http://repository.cmu.edu/dissertations/160.
Full textAbstract:
How do we find patterns and anomalies, on graphs with billions of nodes and edges, which do not fit in memory? How to use parallelism for such Tera- or Peta-scale graphs? In this thesis, we propose PEGASUS, a large scale graph mining system implemented on the top of the HADOOP platform, the open source version of MAPREDUCE. PEGASUS includes algorithms which help us spot patterns and anomalous behaviors in large graphs.
PEGASUS enables the structure analysis on large graphs. We unify many different structure analysis algorithms, including the analysis on connected components, PageRank, and radius/diameter, into a general primitive called GIM-V. GIM-V is highly optimized, achieving good scale-up on the number of edges and available machines. We discover surprising patterns using GIM-V, including the 7-degrees of separation in one of the largest publicly available Web graphs, with 7 billion edges.
PEGASUS also enables the inference and the spectral analysis on large graphs. We design an efficient distributed belief propagation algorithm which infer the states of unlabeled nodes given a set of labeled nodes. We also develop an eigensolver for computing top k eigenvalues and eigenvectors of the adjacency matrices of very large graphs. We use the eigensolver to discover anomalous adult advertisers in the who-follows-whom Twitter graph with 3 billion edges. In addition, we develop an efficient tensor decomposition algorithm and use it to analyze a large knowledge base tensor.
Finally, PEGASUS allows the management of large graphs. We propose efficient graph storage and indexing methods to answer graph mining queries quickly. We also develop an edge layout algorithm for better compressing graphs.

Full textAbstract:
It is widely accepted that climate change is a very serious environmental concern facing the world today. Levels of carbon dioxide (CO2) in the global atmosphere have risen by more than a third since the industrial revolution and are now rising faster than ever before. Power generation accounts for a large proportion of GHGs emissions.
Many different options are being proposed for CO2 emissions mitigation from the power generation sector. They have been extensively investigated in the scientific literature, but selection of better candidates for future investments is difficult and uncertain. Cont/d.

De, Franco Andrea. "Development of a camera for Tera-electron Volt gamma-ray astronomy." Thesis, University of Oxford, 2016. https://ora.ox.ac.uk/objects/uuid:bfa00ea0-3be1-455c-9f82-3429e4bef0da.
Full textAbstract:
In this thesis I describe the development of a compact camera for ground-based multi TeV gamma-ray astronomy, using the Imaging Atmospheric Cherenkov Telescope (IACT) technique. The camera is based on multi-anode photomultipliers (MAPM) and is designed for use on the Gamma Cherenkov Telescope (GCT), which is proposed to be part of the Small Size Telescope (SST) array of the Cherenkov Telescope Array (CTA). GCT achieves high performance with a compact and cost efficient design via a Schwarzschild-Couder (SC) dual-mirror optical system. The GCT optical design allows the use of a compact camera of diameter roughly 0.5 m. The curved focal plane is equipped with 32 tiles of 64-pixels MAPM for a total of 2048 pixels of ~0.2° angular size, resulting in a field of view of ~9°. The GCT camera is designed to record the flashes of Cherenkov light from electromagnetic cascades, which last only a few tens of nanoseconds. I give a detailed description of the design, the challenges encountered during testing in the lab, and the performance of the most critical components. I give details on the custom front-end electronics modules that provide the required fast electronics, facilitating sampling and digitization, as well as first level of triggering. The camera-level triggering system is a custom backplane, developed to reject spurious triggers on the night sky background, which typically is of the order of few tens of millions of photons per pixel per second. This is to be compared with the rate of the astrophysical signal, which is of the order of few hundreds of events per second at the relevant energies. Additionally I provide a detailed description of all the software needed for the data acquisition and control of the camera, from the very low level drivers to high level and user friendly processes. I follow the commissioning of the camera, from the individual core components to the integration of the system. I then describe the integration of the camera on the GCT prototype telescope structure, and the achievement of "first light", validating for the first time the full proof-of-concept of an IACT with SC optics. I also report a study I performed on expectations for an extragalactic survey for blazars with CTA. The cumulative source count distribution of blazars is presented, including implications from two different phenomena: axion-like particle (ALP) to gamma-ray oscillations in the intergalactic magnetic field, and secondary gamma rays from hadronic origins. I conclude that a shallow and wide survey will provide the best science return for CTA, that the impact of ALP is modest and that the secondary mechanism of gamma-ray production would allow detection of blazars up to redshift of 1 in the multi-TeV energy band.

Mohamed, Wanis. "Techno-Economic, Environmental and Risk Analysis (TERA) for Power Generation -Market Growth." Thesis, Cranfield University, 2013. http://dspace.lib.cranfield.ac.uk/handle/1826/7942.
Full textAbstract:
Gas turbines (GTs) are extensively used in many power generation
applications. This project has close coupled advanced, economic diagnostics
with the technology of prime movers using a Genetic Algorithm (GA) to optimise
the economic performance of fleets of GTs for electricity production. The
investigation has included comparative assessment of traditional and novel GT
options, including the design and off-design performance of the engines. The
originality of the work lies in the concurrent technical and economic optimisation
of a fleet of GTs based on a GA using current and novel engine cycles in a wide
range of climatic conditions.
The project has developed an effective model for optimising operational
strategies for off-design conditions capable of optimising the economic
performance of existing fleets of GT engines to meet power requirement while
minimising environmental impact. It has also developed an approach able to
simulate engine operating conditions with attendant costs under different
scenarios based on the Techno-Economic, Environmental, and Risk Analysis
(TERA) philosophy which allows for a broad and multidimensional analysis of
the problem. By integrating the TERA model with in-house performance
simulation software (Turbomatch) it has been possible to simulate the engine
performances at design point and off-design conditions and maximise total
power output at minimum cost to aid equipment selection and plant operation
strategies for new plant.
This study simulated and accounted for the time value of money during the
operational life of the power plant. The model includes a life cycle cost
assessment including: capital cost, maintenance and operating costs, fuel cost
and emission taxes. Using the Net Present Value (NPV) technique the model
was able to make techno-economic comparisons between various modes of
operation and variations in power demand.
Peak load operation requires GTs to operate at high firing temperatures with
consequent reduction in component’ useful life. The techno-economic analysis
found the optimum condition between both operating condition and corresponding strategies and thus includes a comparative lifing model, which
performs stress and thermal analyses, and estimates the component’s minimum
creep life using the Larson Miller method.
A fleet of GT engine operating in a warm coastal environment have been
modelled and investigated in this study. The results showed that the combined
effect of the operating environment and the power demand can have significant
impact on the blade creep life. The ability to predict this impact will aid GT users
in the decision making process associated with GT operation.
The project has developed an emissions model which identifies the GT engine
with smallest impact on global warming and lowest cost of ownership (including
governmental taxation policies) and which will meet a variety of emission
legislation.

Musa, Rebecca Ishaku. "Production and perception of L2 English orthographic and phonological representations by L1 Tera/Hausa speakers : an experimental study." Thesis, University of Newcastle upon Tyne, 2017. http://hdl.handle.net/10443/4023.
Full textAbstract:
Oral English is an integral part of the English language syllabus in Nigeria's secondary schools. However, pronunciation is problematic for students due to factors which include the complexity of grapheme-phoneme correspondences in English, the influence of the students' first language (L1), Tera/Hausa and the method of teaching. Research in second language (L2) acquisition of phonology and on the role of orthographic input has shown that learners’ phonological development can be affected as a result of L2 orthographic input (e.g. Young-Scholten 2002; Rafat 2011 & 2016; Bassetti, Escudero and Hayes-Harb 2015; Bassetti and Atkinson 2015; Young-Scholten and Langer 2015). To this effect, the present study is based on the idea that it is possible to address the difficulties that teaching L2 English pronunciation creates for L1 Tera/Hausa (Chadic languages) speakers. This involved providing L2 orthographic input to see whether it influenced learners’ underlying representations and in turn their oral production. The research involved an intervention study which was aimed at experimentally examining Tera/Hausa speaking secondary school students' production and perception of English orthography and phonological representations with respect to consonant clusters such as clock, straw, and desk, digraphs in clusters such as bench, fridge, and syringe, silent singletons such as knife, signboard, and whistle and digraph singletons such as phone, duck, and ring. The study was conducted with 73 Tera/Hausa speaking secondary school students in Gombe state, Nigeria in pre-testing and post-testing in four sub-tests consisting of two production tasks (picture-naming and reading aloud) and two perception tasks (epenthesis and dictation). A proficiency test was conducted prior to the pre-test which resulted in participants being identified as belonging to three proficiency levels. The learners were randomly (not based on their proficiency) divided into three experimental condition groups and taught eight lessons in 20-minute sessions over four school weeks. Three methods were used for the instruction: listening + orthography group where the group were taught while listening to native speaker recordings of the lessons on an audio player while seeing the written forms; listening-only group, who were taught by only listening to the recordings of the lessons without any written form; and traditional teaching who were taught by a non-native speaking English teacher using the teaching methods normally used in Nigeria to teach English. The hypotheses for the study were based on the idea that although Tera and English both use the Roman alphabet they have their own orthographies, grapheme-phoneme correspondences differ and this will affect Tera/Hausa speakers’ L2 phonology. As a result, without intervention iv at pre-test, it was predicted that the learners will not correctly produce and perceive L2 English consonant clusters, digraphs in clusters, silent singletons and digraph singletons due to problems with the L2 syllable structure. However, with intervention among three experimental condition groups, there will be significant improvement by the group that received explicit phonological and orthographic input than the other groups which did not receive explicit instruction. Qualitative analysis revealed a greater reduction at post-test in error rate by the listening + orthography group on all the error categories on the picture-naming task, reading aloud task and dictation task, compared to the traditional teaching method group and the listening-only group. There was a scattered error reduction rate by the three different proficiency levels. Similarly, in the quantitative analysis, the listening + orthography group yielded significantly greater improvement on the dictation task, picture-naming task and reading aloud task (p ≤ 0.05) compared to the traditional teaching method group and the listening-only group. Although, the traditional teaching method group yielded better improvement on the epenthesis task, the difference between their mean scores with that of the listening + orthography group did not differ significantly (0.22 points). Proficiency level, however, did not significantly influence performance on any of the tasks. The study highlights the effect of orthographic input on Tera/Hausa learners’ production perception in the acquisition of English and uniquely serve as the first phonological acquisition study with African data. The findings of this study allow us to make recommendations for the best and most effective ways of teaching oral English in Nigeria and in secondary schools elsewhere.

El-Suleiman, Abdussalam. "Gas turbine application to CO2 pipeline : a techno-economic and environmental risk analysis." Thesis, Cranfield University, 2014. http://dspace.lib.cranfield.ac.uk/handle/1826/9240.
Full textAbstract:
Gas Turbines (GTs) are used extensively in pipelines to compress gas at suitable points. The primary objective of this study is to look at CO2 return pipelines and the close coupling of the compression system with advanced prime mover cycles. Adopting a techno-economic and environmental risk analysis (TERA) frame work, this study conducts the modelling and evaluation of CO2 compression power requirements for gas turbine driven equipment (pump and compressor). The author developed and validated subroutines to implement variable stators in an in-house GT simulation code known as Variflow in order to enhance the off-design performance simulation of the code. This modification was achieved by altering the existing compressor maps and main program algorithm of the code. Economic model based on the net present value (NPV) method, CO2 compressibility factor model based on the Peng-Robinson equation of state and pipeline hydraulic analysis model based on fundamental gas flow equation were also developed to facilitate the TERA of selected GT mechanical drives in two case scenarios. These case scenarios were specifically built around Turbomatch simulated GT design and off-design performance which ensure that the CO2 is introduced into the pipeline at the supercritical pressure as well as sustain the CO2 pressure above a minimum designated pressure during transmission along an adapted real life pipeline profile. The required compression duty for the maximum and minimum CO2 throughput as well as the operation site ambient condition, guided the selection of two GTs of 33.9 MW and 9.4 MW capacities. At the site ambient condition, the off design simulations of these GTs give an output of 25.9 MW and 7.6 MW respectively. Given the assumed economic parameters over a plant life of 25 years, the NPV for deploying the 33.9 MW GT is about £13.9M while that of the 9.4 MW GT is about £1.2M. The corresponding payback periods (PBPs) were 3 and 7 years respectively. Thus, a good return on investment is achieved within reasonable risk. The sensitivity analysis results show a NPV of about £19.1M - £24.3M and about £3.1M - £4.9M for the 33.9 MW and 9.4 MW GTs respectively over a 25 - 50% fuel cost reduction. Their PBPs were 3 - 2 years and 5 - 4 years respectively. In addition, as the CO2 throughput drops, the risk becomes higher with less return on investment. In fact, when the CO2 throughput drops to a certain level, the investment becomes highly unattractive and unable to payback itself within the assumed 25 years plant life. The hydraulic analysis results for three different pipe sizes of 24, 14 and 12¾ inch diameters show an increase in pressure drop with increase in CO2 throughput and a decrease in pressure drop with increase in pipe size for a given throughput. Owing to the effect of elevation difference, the 511 km long pipeline profile gives rise to an equivalent length of 511.52 km. Similarly, given the pipeline inlet pressure of 15 MPa and other assumed pipeline data, the 3.70 MTPY (0.27 mmscfd) maximum average CO2 throughput considered in the 12¾ inch diameter pipeline results in a delivery pressure of about 15.06 MPa. Under this condition, points of pressure spikes above the pipeline maximum operating allowable pressure (15.3 MPa) were obtained along the profile. Lowering the pipeline operating pressure to 10.5 MPa gives a delivery pressure of about 10.45 MPa within safe pressure limits. At this 10.5 MPa, over a flat pipeline profile of same length, the delivery pressure is about 10.4 MPa. Thus, given the operating conditions for the dense phase CO2 pipeline transmission and the limit of this study, it is very unlikely that a booster station will be required. So also, compressing the CO2 to 15 MPa may no longer be necessary; which eliminates the need of combining a compressor and pump for the initial pressure boost in order to save power. This is because, irrespective of the saving in energy, the increase in capital cost associated with obtaining a pump and suitable driver far outweighs the extra expense incurred in acquiring a rated GT mechanical drive to meet the compression duty.

Full textAbstract:
Haemoglobin A1c is besides glucose the most requested analysis for diagnosing diabetes due to its ability to predict diseases that occur due a high blood sugar. The analysis has some limitations when a haemoglobin variant is present as they may cause falsely low or high results. In this study, we used whole blood from routine requested haemoglobin A1c samples for screening for haemoglobin variants with Capillarys 3 TERA. The samples with haemoglobin variants was then analysed with Cobas c501, Roche and Afinion, Alere for comparison of the methods. The aim of this study was to investigate the presence of haemoglobin variants in the county of Uppsala by screening over 3000 haemoglobin A1c samples. Samples with known haemoglobin variant was analysed as above to compare the results with those found in our county to study the possibility to identify the haemoglobin variants with Capillarys 3 TERA. The presence of haemoglobin variants in the county of Uppsala was approximately 0.5%. Correlation between Cobas c501 and Capillarys 3 TERA was strong for samples with haemoglobin F (r = 0.988) and for the samples with haemoglobin variants the correlations coefficient was 0.94. Correlation coefficients between Afinion and Capillarys 3 TERA for samples with haemoglobin F was 0.987 and for the haemoglobin variant 0.937. The presence of haemoglobin variants in the county of Uppsala is still low. Capillarys 3 TERA is capable to separate the most common variants and despite the good correlation every haemoglobin variant needs to be handled separately and the results should be answered with a comment that there is a possibility that the haemoglobin variant is giving an incorrect result.

2008/2009L'importanza e l'interesse dell’argomento di questa tesi di dottorato discendono dalla centralità che il culto di Apollo Carneo aveva nell'ambito della religione e della società spartana, esemplificata dal modo in cui la festività ad esso connessa poteva incidere sull’andamento di alcuni eventi bellici fondamentali nella storia greca. Il culto di Apollo Carneo, infatti, era diffuso nella maggior parte delle poleis greche doriche ed era particolarmente sentito a Sparta. Esso comportava l’astenersi dalle guerre per tutta la durata della festa. Si possono individuare le conseguenze di tale divieto in alcuni passi di Erodoto e di Tucidide: gli Spartani non giunsero in aiuto degli Ateniesi nella battaglia di Maratona perché dovevano attendere la fine delle celebrazioni delle Carnee prima di partire (Hdt. VI 106,3); gli Spartani inviarono alle Termopili un piccolo contingente agli ordini di Leonida proprio perché in quel periodo si svolgevano le Carnee e non poteva essere inviato tutto l’esercito (Hdt. VII 206); nel corso della guerra del Peloponneso gli Spartani interrompevano l’attività bellica durante la celebrazione delle Carnee, mentre gli Argivi cercarono, con un artificio nel computo dei giorni, di rimandare l’inizio del mese Carneo, mese sacro ai Dori secondo Tucidide, per poter concludere un’incursione nel territorio di Epidauro (Thuc. V 54; V 75; V 76,1). Da questi esempi si evince chiaramente come lo studio del culto di Apollo Carneo non possa essere considerato come un mero studio di erudizione sulle peculiarità della religione greca, ma investa invece gli aspetti fondamentali della società spartana (oltre che della colonia di Thera, della sub-colonia di Cirene e delle altre città interessate dal culto), al punto che numerosi studiosi si sono cimentati nell’interpretazione del significato delle Carnee. Adler, però, conclude la voce Karneios della Real Encyclopedie der Classischen Altertumswissenschaft in modo piuttosto sconsolato: “Jedenfalls liegt die Ausbreitungsgeschichte des Kultes nach dem Erscheinen des neuen Materials mehr im Dunkel als vorher”. In seguito sono stati pubblicati numerosi studi importanti ed illuminanti, ma il quadro complessivo della festa rimane ancora incerto e contraddittorio. Il presente progetto di ricerca, pertanto, intende sì offrire una raccolta completa delle testimonianze sul culto di Apollo Carneo, comprese le più recenti acquisizioni epigrafiche, numismatiche ed archeologiche, ma intende soprattutto trattare l’argomento da un punto di vista diverso. L’impostazione sottesa alla tesi, infatti, non prevede l’utilizzo indistinto di tutte le testimonianze, di qualsiasi periodo, per tracciare un quadro generale ed onnicomprensivo del culto, valido per tutte le epoche, bensì contempla un approccio diacronico che consenta di riconoscere gli influssi e i cambiamenti che di volta in volta il contesto politico, sociale e culturale ha imposto. Il tentativo, insomma, è di tracciare un quadro dell’evoluzione storica di questa festività, adottando, ove possibile, un criterio ‘stratigrafico’ nell’analisi dei testi sulle Carnee. Il primo capitolo comprende una rassegna delle numerose interpretazioni del culto: esse considerano Apollo Carneo un’originaria divinità della vendemmia oppure un dio-ariete, legato ad una festa di pastori; pongono un più marcato accento sui riti di purificazione ed espiazione e sul collegamento con la caccia e con la preparazione per la guerra o sottolineano la prevalenza del carattere iniziatico della festa. Per la maggior parte degli studiosi nella festa si può individuare uno strato più antico, che riguarda il culto della natura per pastori e contadini, e uno strato più recente, in cui prevale l’aspetto militare, introdotto dai Dori. Le posizioni emerse negli ultimi anni tendono a valorizzare maggiormente l’aspetto militare del culto, il legame con la migrazione e la conquista dorica. Nel secondo capitolo le tradizioni sulle origini delle Carnee sono catalogate secondo due criteri: quello cronologico e quello tematico. Nella prima parte sono analizzate in ordine cronologico tutte le fonti letterarie che si riferiscono al mito eziologico delle Carnee. La testimonianza più antica risale al VII secolo a.C., ad Alcmane, a cui lo scolio 83a all’Idillio V di Teocrito attribuisce un frammento in cui viene citato Karnos, mentre gli autori più tardi sono Nonno ed Esichio. Il dato più significativo è costituito proprio dall’ampio arco cronologico (si va dal VII secolo a.C. al V-VI d.C.) e dall’estrema varietà delle informazioni desumibili dalle fonti: in taluni casi risulta difficile combinare in un unico contesto festivo e cultuale tutti i dati a nostra disposizione. Si è deciso, perciò, di adottare nella prima parte del secondo capitolo un criterio ‘stratigrafico’, ovvero un approccio diacronico che consenta di riconoscere gli influssi del contesto politico, sociale e culturale sull’evoluzione storica di questa festività. Tale modo di accostarsi al problema delle fonti, inoltre, ben si accorda con l’immagine, ormai unanimemente accettata negli studi specialistici, di una Sparta che muta nel corso del tempo e non rimane sempre uguale a se stessa. La seconda parte del capitolo, invece, prende in considerazione le medesime fonti seguendo un criterio tematico, in modo da definire chiaramente i tre nuclei tematici intorno ai quali raggruppare le testimonianze. Il primo spiega l’origine del culto di Apollo Carneo richiamandosi all’ambito della spedizione di Troia (Alcmane, Demetrio di Scepsi, Pausania e lo scolio a Teocrito V 83 d); il secondo si rifà al cosiddetto ritorno degli Eraclidi (Teopompo, Conone, Pseudo-Apollodoro, Pausania, scoli a Teocrito V 83c-d e scoli a Callimaco, Inno ad Apollo 71); il terzo fa discendere Karnos da Zeus ed Europa (Prassilla, Pausania ed Esichio). Il terzo capitolo, sulle manifestazioni locali del culto, costituisce il nucleo centrale della tesi. Nella prima sezione vengono trattati gli aspetti del culto per i quali non si può individuare una provenienza locale ben definita: l’iconografia e la collocazione della festa nel calendario. Nel paragrafo sull’iconografia viene evidenziato il legame con il culto del Carneo di alcune erme laconiche che raffigurano un ariete e di una stele alla cui sommità è scolpito in bassorilievo un paio di corna di ariete. Allo stesso tempo, però, viene messa in dubbio la possibilità che il tipo monetale che ritrae una testa giovanile con corna e, talvolta, orecchie di ariete rappresenti Apollo Carneo. Tali monete provengono da numerosi centri della madrepatria e delle colonie greche, tra i quali – ciò che più conta ai fini dell’interpretazione – molte località non doriche (ad esempio Metaponto, Tenos, Aphytis, ecc.). Tra le altre identificazioni proposte dagli studiosi, la più plausibile sembra essere quella con Zeus Ammone. La parte più ponderosa del terzo capitolo riguarda l’analisi delle manifestazioni del culto a Sparta, Tera, Cirene e Cnido, da cui proviene una quantità di dati sufficiente ad analizzare con una certa sistematicità le testimonianze relative al Carneo. In ogni capitolo vengono esaminati l’eventuale localizzazione topografica dei santuari di Apollo Carneo, le attestazioni di agoni (musicali e/o atletici) all’interno delle Carnee, i riti connessi al culto, l’esistenza di sacerdozi del Carneo. Per molti aspetti la scarsità e la natura eterogenea della documentazione, sia tra una città e l’altra sia all’interno di una stessa città, rendono difficile proporre un’interpretazione complessiva del culto. L’esempio di Cirene è emblematico: le fonti letterarie attestano con certezza l’esistenza e l’importanza del culto di Apollo Carneo, soprattutto in relazione alla fondazione della città, mentre la documentazione archeologica, che pure è singolarmente abbondante per Cirene, non ci consente di localizzare gli eventuali santuari del dio all’interno della città. Il quarto capitolo raccoglie le altre testimonianze del culto che ne attestano la diffusione in ambito dorico. Le località per le quali possediamo una documentazione sufficientemente consistente sono Cos, Lindo e Camiro, Messene e Andania. In conclusione, se sembra difficile proporre un’interpretazione totalizzante, che colleghi tutti gli elementi del culto in un sistema “où tout se tient”, si possono, però, individuare alcuni caratteri comuni alle diverse manifestazioni del culto. Innanzitutto le associazioni del Carneo con determinate divinità (Era, Ilizia, Artemide, i Dioscuri) connesse all’educazione dei giovani e il rito della staphylodromia fanno intravedere un ruolo del dio nella formazione e nell’inserimento dei giovani tra i cittadini a pieno titolo, ma non, a mio parere, un inquadramento strutturale del culto nel sistema iniziatico spartano. In secondo luogo il culto e la festa avevano una forte caratterizzazione ‘politica’, in cui tutti gli elementi costitutivi dell’identità e dell’ideologia del gruppo – soprattutto, da un certo momento in poi, l’elemento dorico – erano enfatizzati.

Full textAbstract:
Au Niger, la maîtrise des ressources en eau demeure toujours un défi majeur après plus de 50 ans de politique hydraulique. Les investissements réalisés durant la Décennie Internationale de l’Eau Potable et de l’Assainissement (1981-1990) et les Objectifs du Millénaire pour le Développement (2000-2015) n’ont pas pu couvrir les besoins énormes en eau. Le déficit en infrastructures se pose au niveau de toutes les composantes du secteur de l’hydraulique. Les besoins en eau de plus en plus croissants et l’insuffisance des investissements publics pour y faire face expliquent ce sous-équipement en infrastructures hydrauliques. Au niveau de la commune urbaine de Téra, au-delà de la forte croissance démographique et de l’insuffisance des investissements dans le secteur de l’eau, il faut ajouter les contraintes climatiques et hydrogéologiques dans l’analyse de la situation hydraulique. Dans la ville de Téra, la précarité hydrique est due à un déficit considérable de production d’eau et à un réseau de distribution d’eau inadapté au site de la ville. Ainsi, de décembre à août, les trois quarts de la ville, principalement les quartiers Carré, Résidence, Douane, TP et Guenobon restent sans être desservis en eau. En milieu rural, l’insuffisance des points d’eau, leur localisation par rapport aux villages et le temps de rétention assez court (3 à 4 mois) des plans d’eau entraînent une situation d’extrême précarité hydrique qui bouleverse la vie socio-économique. En ville comme en campagne, en dépit des différences territoriales et des modalités d’accès à l’eau, les populations vivent le même niveau de précarité hydrique et y apportent les mêmes types de solutions. Elles recourent ainsi aux points d’eau traditionnels et développent une solidarité hydraulique à travers la mutualisation des points d’eau entre quartiers, entre villages et entre ville-villages. Mais, avec cette situation hydraulique particulièrement précaire réduisant systématiquement la pratique des activités économiques et la satisfaction des besoins humains fondamentaux, les défis de développement local deviennent de plus en plus lourds pour la commune urbaine de TéraIn Niger, water resource management remains a major challenge after more than 50 years of water policy. Thus, the investments carried out during the International Decade of Driking Water and Sanitation (1981-1990) and the Millennium Development Goals (2000-2015) could not meet the enormous needs of water. The infrastructure deficit is being faced by all components of the hydraulic sector. The growing demand for water and insufficient public investment to meet it explain this under-equipment in water infrastructure. At the level of the urban district of Tera, in addition to the strong demographic growth and insufficient investments in the water sector, climatic and hydrogeological constraints must be added to the analysis of the hydraulic situation. In the city of Tera, the hydrous precariousness is due to a considerable lack of water production and an inadequate water distribution network at the city site. Thus, from december to august, three-quarters of the city, mainly the Carré, Résidence, Douane, TP and Guenobon neighbourhoods remain underserved. In rural areas, the insufficiency of water supply points, their location in relation to villages to the villages and the rather short time of retention (3 à 4 months) of lakes defines a situation of extreme hydrous precariousness which affects the socio-economic life. In town as in the countryside, despite the territorial differences and water access methods, the populations face the same level of hydrous precariousness and adopt the same types of solutions. Thus, they resort to the traditional water supply points and develop a hydraulic solidarity through the mutualisation of water supply points between districts, villages, villages and city. However, with this particularly precarious hydraulic situation systematically reducing the practice of economic activities and the satisfaction of the fundamental human needs, the challenges of local development become increasingly heavy for the urban district of Tera

Full textAbstract:
Although there have been two-dimensional electrophoretic studies on fetal brain tissue (for instance, Yoshida and Takahashi, 1980), the emphasis in most of this work has been on developmental changes in protein expression, and not on the effects that drugs have on fetal brain protein complement. Klose and co-workers (1977) did an early study using two-dimensional gel electrophoresis to determine the effects of various teratogens on whole embryos. No protein changes were found and that line of research was not continued. In this study two-dimensional gel electrophoresis is extensively used, in the belief that the usefulness of this technique to experimental teratology has not been fully evaluated. It is reasonable to suppose that a central nervous system teratogen administered during critical periods of susceptibility will led to perturbations of orderly brain development, and that these perturbations will be reflected as changes to the protein complement. The total brain protein complement of mice that have been exposed to drugs in utero will therefore be analysed, in the hope that any inductions or deletions of proteins as a result of drug exposure may provide a clue to the molecular events underlying drug injury to the fetus.

Full textAbstract:
Environ 10 % des patients atteints de fibrose pulmonaire idiopathique (FPI) ont au moins un apparenté atteint de pneumopathie interstitielle diffuse (PID). Des mutations avaient été mises en évidence sur les gènes codant pour les protéines impliquées dans le métabolisme du surfactant et les protéines du complexe télomérase. Chez l’adulte, les mutations de TERT étaient les plus fréquentes (˜15 %), les mutations de TERC, DKC1 et TINF2 plus rarement retrouvées. Environ 80 % des formes familiales de fibroses pulmonaires chez l’adulte étaient sans cause identifiée. Les objectifs de cette thèse étaient : 1) d’identifier un nouveau gène en cause dans les fibroses pulmonaires familiales de l’adulte inexpliquées, 2) de mieux caractériser le phénotype des patients présentant des mutations de TERT, de TERC ou du nouveau gène mis en évidence.Nous avons sélectionné 35 familles présentant une fibrose pulmonaire familiale pour lesquelles la recherche de mutation TERT, TERC, ABCA3, SFTPB et SFTPC était négative, pour réaliser un séquençage de l’exome. Quatre familles sur les 35 analysées présentaient un variant très rare sur RTEL1 à l’état hétérozygote. La présence des variants a été confirmée par séquençage selon la méthode de Sanger. Ces variants étaient absents des bases de données de contrôles. Les prédictions in silico étaient en faveur du caractère pathogène de ces variants. Les variants co-ségrégeaient avec la maladie dans les familles.L’analyse des variants à partir de la modélisation en 3D de la protéine suggérait un impact fonctionnel des variants sur le site de fixation à l’ATP ou à l’ADN. La taille des télomères des patients étaient raccourcies en comparaison des témoins de la même catégorie d’âge. En 2014, 237 patients avec une fibrose pulmonaire (153 avec une fibrose pulmonaire familiale, 84 avec un syndrome télomère) avaient bénéficié d’un séquençage de TERC et de TERT. Les variants ont été classés comme pathogènes chez 40 patients (16,8 %). Un âge de survenue précoce de fibrose, une macrocytose, ou une thrombopénie étaient significativement associée avec la présence d’une mutation. La probabilité d’une mutation était la plus importante pour les patients de 40-60 ans. La médiane de survie sans transplantation était plus faible pour les patients porteurs de mutations de TERT ou de TERC. Nous avons réalisé un séquençage de l’exome chez 40 autres familles et mis en évidence 5 nouveaux variants de RTEL1 probablement pathogènes in silico. Nous avons par ailleurs mis en évidence 3 autres mutations de RTEL1 dans une cohorte de PID associées à une polyarthrite rhumatoïde. Nous avons colligé les données de 35 patients atteints de PID et porteurs de mutations hétérozygotes de RTEL1. Vingt patients présentaient une FPI (57 %) et 10 une PID secondaire (25,7%). A la différence des mutations de TERT ou TERC, les mutations de RTEL1 étaient associées à moins d’anomalies hématologiques. Par ailleurs, l’expression pulmonaire de la protéine RTEL1 évaluée par immuno-histochimie et de l’ARNm par PCR était équivalente chez les patients porteurs de mutations RTEL1, de TERT ou atteints de FPI sans mutation. Nous avons identifié et confirmé l’implication d’un nouveau gène, RTEL1, dans environ 10 % des fibroses pulmonaires familiales. La présence d’une macrocytose, d’une thrombopénie ou d’un âge jeune en présence d’une forme familiale de fibrose est prédictive de la présence d’une mutation de TERT ou de TERC. La pénétrance des maladies hématologiques semble plus faible pour les mutations de RTEL1 que pour celles de TERT ou TERC dans notre cohorte recrutée sur l’atteinte pulmonaire. Les mutations de TERT ou de RTEL1 sont fréquemment associées à des PID secondairesAbout 10% of patients with idiopathic pulmonary fibrosis (IPF) have at least one relative with interstitial lung disease (ILD). Mutations had been reported on the genes encoding for the proteins involved in the surfactant metabolism and in the telomerase complex In adults, TERT mutations were the most frequent (˜15%), mutations of TERC, DKC1 and TINF2 more rarely found. Approximately 80% of the familial forms of pulmonary fibroses in adults were unidentified. The objectives of this work were: 1) to identify a new gene involved in unexplained adult familial pulmonary fibrosis, 2) to better characterize the phenotype of patients with mutations of TERT, TERC or the new gene detected. We selected 35 families with familial pulmonary fibrosis for which the TERT, TERC, ABCA3, SFTPB and SFTPC mutation search was negative, to perform exome sequencing. Four of the 35 families analyzed showed a very rare variant on RTEL1 in the heterozygous state. The presence of the variants was confirmed by Sanger sequencing. These variants were absent from the control databases. In silico predictions were in favor of the pathogenicity of these variants.In families, the variants co-segregated with the disease. In 3D modeling, analysis of the variants suggested a functional impact at the ATP or DNA binding site. The telomere length of carriers of the mutations was shortened compared to controls in the same age group. In 2014, 237 patients with pulmonary fibrosis (153 with familial pulmonary fibrosis, 84 with telomere syndrome) were sequenced for TERC and TERT. The variants were classified as pathogenic in 40 patients (16.8%). An early age of diangosis, macrocytosis, or thrombocytopenia were significantly associated with the presence of a mutation.The probability of a mutation was greatest for patients aged 40-60 years. The median survival without transplantation was lower for patients with TERT or TERC mutations.We performed a sequencing of the exoma in 40 other families and showed 5 new variants of RTEL1 probably pathogenic in silico. We also demonstrated 3 other mutations of RTEL1 in a cohort of ILD associated with rheumatoid arthritis. We collected data from 35 patients with ILD carriers of RTEL1 heterozygous mutations. Twenty patients had IPF (57%) and 10 a secondary ILD (25.7%). Unlike mutations within TERT or TERC, RTEL1 mutations were associated with fewer hematological abnormalities.Furthermore, the pulmonary expression of the RTEL1 protein evaluated by immunohistochemistry and mRNA by PCR was equivalent in patients carriers of RTEL1 or TERT mutations or IPF without mutation. We identified and confirmed the implication of a new gene, RTEL1, in about 10% of familial pulmonary fibroses. The presence of macrocytosis, thrombocytopenia or a young age is predictive of the presence of a mutation within TERT or TERC. The penetrance of hematological diseases appears to be lower for RTEL1 mutation carriers than for TERT or TERC mutation carriers in our cohort of ILD patient. Mutations of TERT or RTEL1 are frequently associated with secondary ILD

Mestrado em Ensino de Física e QuímicaEsta dissertação de Mestrado centra-se na preparação, aplicação e avaliação de um projecto interdisciplinar no âmbito da Área Curricular Ciências Físicas e Naturais do 3.º ciclo do Ensino Básico. Tem como objectivo estudar formas de superar as dificuldades, já diagnosticadas, que os professores sentem aquando a implementação de práticas interdisciplinares. Deste modo o trabalho desenvolveu-se em duas etapas: contacto com a escola, preparação e negociação com os professores das estratégias a dinamizar, aplicação no terreno das actividades previamente planeadas e avaliação do trabalho efectuado. O projecto envolveu uma turma do 7.º ano de escolaridade e quatro professores. O estudo é de natureza qualitativa, isto porque há uma preocupação de compreender uma dada situaçao real e não de generalizar resultados. A recolha de dados fez-se por observação naturalista, por snapshops, por questionário aos professores e aos alunos e pelas actas das reuniões. O tratamento de dados foi feito com recurso à análise de conteúdo. O objectivo do projecto foi atingido pois o cruzamento dos resultados evidenciam as potencialidades do desenvolvimento de um projecto interdisciplinar quer ao nível dos professores, quer ao nível dos alunos. Apesar da turma envolvida apresentar alunos pouco motivados e com dificuldades cognitivas, o desenvolvimento do projecto contribuiu para o envolvimento dos alunos assim como para o desenvolvimento de algumas competências, em particular ao nível das competências transversais. A importância do estudo traduz-se no contributo que pode dar, quer ao nível da investigação educacional, quer da formação inicial e contínua de professores em particular por apresentar actividades que podem servir de inspiração para o desenvolvimento de novos projectos desta natureza. ABSTRACT: This Master dissertation focuses on the preparation, implementation and evaluation of an interdisciplinary Project under the Curricular Area Physical and Natural Sciences of the 3rd cycle of basic education. It aims to explore ways to overcome the difficulties, as diagnosed in other studies, that teachers feel when the implementation of interdisciplinary practise. Then, the works developed in two stages: contact with the school, preparing and negotiating with the teachers of the strategies to apply, implementation on the ground of the activities, previously planned, and evaluation of the work. The study involved, pupils of the 7th year of schooling and four teachers. The study is of a qualitative nature, because there is a concern to understand a given real situation and not to generalize results. The collection of data has been based on naturalistic observation, “snapshops”, questionnaires to teachers and pupils and the minutes of meetings with the teachers. Data processing was done using content analysis. The aim of the project was reached because the results of the study show the potential of development of an interdisciplinary project either at the level of teachers, and of the pupils. Despite the pupils involved present little motivation for learning and reveal some cognitive difficulties, the development of the project contributed to their involvement, as well as for the development of some competences, particularly at the level of transversal ones. The importance of the study reflected in the contribution that we can make, both in terms of educational research, and of initial and continuous training of teachers in particular, because this work presents activities that can serve as inspiration for the development of new projects of this nature.

Abstract
La Long Term Care (LTC) è una polizza, che copre le spese derivanti dall’impossibilità di svolgere autonomamente le normali attività quotidiane (azioni basiche come muoversi, lavarsi e mangiare) a lungo termine, generando una lesione all’ autosufficienza, causata anche, ma non obbligatoriamente, da malattia o infortunio.
Tale polizza viene, in alcuni Paesi concessa gratuitamente, oppure acquistata per evitare la possibilità di non essere autosufficienti in età avanzata, come in caso di bisogno di una badante o di recarsi presso una casa di cura o per avere la necessaria assistenza sanitaria. Essa è presente nella maggioranza dei paesi avanzati ed è un segnale del preoccupante aumento del numero di anziani.
Tale fenomeno sta caratterizzando soprattutto la Cina, in cui viene sottolineata l'importanza dell'assistenza a lungo termine per gli anziani. Il numero di persone di età pari o superiore a 65 anni è aumentato da 96 milioni nel 2003 a 150 milioni nel 2016, alcuni dei quali disabili a causa di malattie croniche o per effetti naturali dell'invecchiamento. Pertanto, la misurazione dell’impatto, anche economico, della LTC è di fondamentale importanza.
La presente tesi di laurea analizza l’esperimento pilota riguardante il programma di assistenza sanitaria denominato LTCI e condotto su quindici città campione al fine di identificare quale parte della popolazione necessitasse di maggiore supporto e di quale tipo. Lo scopo è capire ed interpretare i possibili interventi.

No presente trabalho é abordada a manobra orbital Terra-Lua - Terra com o objetivo de um menor consumo de combustível. Inicialmente o satélite executa uma órbita em torno da Terra. Em um certo instante um impulso é efetuado para efetuar uma manobra não con-focal em que o satélite é transferido para uma órbita de transferência geocêntrica até um ponto da esfera de influência da Lua. A partir deste ponto o satélite é transferido para uma órbita hiperbólica em torno da Lua, e, no perilúnio desta órbita um novo impulso é dado transferindo o satélite para uma órbita lunar.

From this point the satellite is transferred to a hyperbolic orbit around the Moon, and, in the perilúnio of this orbit a new impulse is given transferring the satellite to a lunar orbit.

As inovações na área da Tecnologia da Informação têm proporcionado grandes mudanças no método de pensar da sociedade moderna. Neste âmbito, também a educação, embora um termo tão antigo e tradicional, está abrindo espaço para acrescer tais novidades. Professores possuem novos mecanismos de transmissão de conhecimentos e alunos, cada vez mais, requerem novas tecnologias, tanto nas salas de aula quanto nos cursos promovidos à distância. Esta dissertação descreve o ambiente TEIA # Tecnologia de Ensino com Inteligência Aplicada. Tal sistema foi desenvolvido especialmente para ser um protótipo de um ambiente educacional, com suporte de Agentes Inteligentes, definidos por meio da Inteligência Artificial. Procurou-se, através das referências bibliográficas, oferecer um embasamento pedagógico inicial, com enfoque à aprendizagem cognitiva, não esquecendo de citar a área da Inteligência Artificial, que é o principal ponto de apoio deste sistema. O ambiente TEIA, além de permitir o cadastro e gerenciamento de vários cursos concomitantes e em diferentes áreas, apresenta algumas funcionalidades, como temas de fórum, salas de bate-papo, documentos disponíveis na biblioteca, etc. Alguns destes itens são providos de inteligência, como é o caso da sala de batepapo, que exibe um tutor virtual inteligente, bem como outros itens neste estilo, objetivando a defesa de que é possível construir um ambiente interativo inteligente para auxiliar a educação nos tempos atuais.

Orientador: Fernanda Cátia BozelliResumo: Apesar de existir vários atributos que justificam o ensino de Astronomia nas escolas, ainda é possível verificar nos últimos anos, por meio de pesquisas, que professores apresentam dificuldades em abordar esse conhecimento. Deste modo, que ensino de Astronomia tem sido praticado nas escolas considerando-se uma quantidade relevante de pesquisas já existentes na área de Ensino de Ciências, bem como de orientações oficiais? Esse e outros questionamentos levantados no contato com materiais didáticos, professores, escolas e leituras de pesquisas em ensino de Ciências levaram a seguinte questão de pesquisa: Comparando-se o Discurso Oficial e o de professores que lecionam Física, o que se pode dizer acerca do ensino de temas relacionados à Astronomia no Ensino Médio? Nesta pesquisa, buscou-se comparar o Discurso Oficial, proveniente de documentos oficiais (Parâmetros Curriculares Nacionais para o Ensino Médio (PCNEM), Currículo do Estado de São Paulo, Orientações Curriculares Complementares aos Parâmetros Curriculares Nacionais (PCN+), Diretrizes Curriculares Nacionais para o Ensino Médio (DCNEM)) e o Discurso do Professor que leciona Física, a fim de se discutir o que é possível dizer acerca do ensino de temas relacionados a Astronomia. A pesquisa é de natureza qualitativa e foi realizada com professores que lecionam a disciplina de Física no primeiro Ano do Ensino Médio de uma escola pública do interior do estado de São Paulo por meio da realização de entrevistas semiestruturadas....

Abstract: Although there are several attributes to justify astronomy teaching in schools, it is possible to verify in recent years, through research, that teachers have difficulties in working with this topic. Thus, what kind of Astronomy teaching has been practiced in schools considering a relevant amount of research already existing in the area of Science Teaching, as well as official guidelines? This and other questions raised through the contact with teaching materials, teachers, schools and readings of research in science teaching led the following research question: Comparing the Official Discourse and that one of Physics teachers, what can be said about the teaching topics related to Astronomy in High School? In this research, we sought to compare the Official Discourse, from official documents (National Curriculum Parameters for Secondary Education (PCNEM), State of São Paulo Curriculum, Complementary Curricular Guidelines for National Curricular Parameters (PCN +), National Curricular Guidelines for High School (DCNEM)) and the Professor's Discourse of Physics teachers, in order to discuss what can be said about the topics related to astronomy teaching. The research has a qualitative nature and was carried out with Physics teachers that lecture in the first year of high school of a public institution in the state of São Paulo, through semi-structured interviews. Data analysis was based on the French Discourse Analysis using Eni Orlandi’s framework. The results show that the te... (Complete abstract click electronic access below)

Full textAbstract:
Il seguente lavoro di tesi si pone l’obiettivo di caratterizzare la granulometria totale e di ricostruire i parametri eruttivi, tramite l’utilizzo dei modelli numerici FPLUME e Fall3D, delle eruzioni dell’Etna avvenute nelle giornate dal 3 al 5 dicembre 2015.
Gli eventi parossistici, che hanno avuto luogo principalmente dal cratere Voragine, hanno generato imponenti colonne eruttive ed i tefra rilasciati in atmosfera sono stati trasportati dal vento fino in Calabria, permettendo così la collezione di dati nelle zone
distali. Per prima cosa è stata ricostruita la TGSD attraverso la tassellazione di Voronoi e, una volta parametrizzata con distribuzioni di tipo bi-Weibull e bi-Gauss, è stata data in input ai modelli di cui sopra, insieme ad altri parametri presenti nella letteratura scientifica. Modificando opportunamente i parametri di input e confrontando le simulazioni ottenute e i dati di carico a terra a nostra disposizione, attraverso metodi statistici appropriati, si sono osservati risultati migliori con la parametrizzazione della TGSD tramite distribuzione bi-Weibull. E' stata dunque stimata una massa complessiva eruttata tra i ≈ 7 · 10^9 kg ed i 10^10 kg per un altezza massima della colonna di circa 14 km sul livello del mare. Dalle simulazioni risulta inoltre la presenza, all’interno del dominio computazionale, di concentrazioni di tefra in atmosfera superiori ai 2 mg/m^3 fino a 6 ore dopo la conclusione degli eventi parossistici.

Full textAbstract:
Lentiviruses have paradoxically fast short-term rate of evolution and slow long-term rate of evolution, which differ by several orders of magnitude. In this thesis, with a new method called truncated tree analysis, slower rates of evolution of transmitted viruses were estimated. However, the rate decline of the transmitted viruses is limited, and is not sufficient to explain the dramatic difference between the short-term and long-term evolutionary rates. These dramatically different rates were reconciled by an S shaped curve based on the new trend observed from this thesis. In the middle part of this new trend, the rate of evolution decreases as the time of divergence increases. Using this new trend, the time scale of HIV -1 and their closest related SIV found in apes were set. The SIV cpzPtt and SIV cpzPts isolated from the two subspecies of chimpanzees shared the most recent common ancestor around 25.2 thousand years ago. This is younger than the estimated date of these two host subspecies split, and suggests that the SIV cpz is relatively new to the chimpanzees. The second chapter of this thesis further explores lentiviral evolution by examining the feline immunodeficiency viruses (FIV's). An American origin scenario of the FIV s was proposed. In this scenario the ancestor of FIV first the invaded the ancestors of the puma lineage living in American, and then as the ancient puma lineage speciated and migrated FIV spread out to many other felids. The final chapter of this thesis further explores the evolutionary rate decline as the time span extends by introducing the idea of flip- flop sites that undergo negative frequency dependent selection pressures. Theoretical simulations confirmed that in the short time span, the presence of the flip-flop sites results in overestimation of the evolutionary rate, but in longer time spans, opposite effects of flip-flop sites were observed.

Tierra rara es un rescate de la tierra como elemento de pertenencia mediante practicas de intervención en el espacio publico realizadas durante el período de Maestría en la Universidade do Estado de Santa Catarina. Como rutas de escape dibujadas contra el asfalto, o el racionalismo dominante en las normas hegemónicas de construcción de las ciudades, los textos apuntan para el uso común de los espacios por cada uno de nosotros. Tierra rara es una cartillage en defensa al libre acceso a los bienes de uso común del pueblo, y de la refuncionalización para transformación de toda condición opresiva en el día a día. Tierra rara es colocar paredes abajo, saltar vallas, romper en el beco e descubrir que la ciudad tiene lugares atesorados para la conveniencia de unos en detrimento de toda la comunidad. El valor de la tierra no puede reducirse al precio de especulación en el mercado, simplemente porque la tierra no pertenece a nosostros, nosotros pertenecemos a la tierra. El derecho a un ambiente equilibrado implica la percepción de la tierra como elemento indispensable para nuestra supervivencia. Este es el punto de partida para la reconstrucción de nuestra ciudadanía como florestanía. Tierra rara es una iniciación al cultivo de espacios publicos, o que tanto quiere decir una cultura de uso común de los espacios como el cultivo en sí, es decir, la necesidad de asumir la responsabilidad por el cultivo de ciudades con más tierra, con más verde, más pajaritos, más insectos y, consecuentemente, mejor calidad de vida para todos sus habitantes.

Estudos divulgados pelo Ibope (2012), Google (2013) e Nielsen (2015) indicam que boa parte da população brasileira está habituada a utilizar um dispositivo móvel enquanto assiste à televisão a comentar nas redes sociais sobre o programa assistido. Esse fenômeno tem sido denominado como TV Social e a plataforma em que isso ocorre como segunda tela. Observando essa tendência do público, emissoras lançaram aplicativos(apps) para estimular a audiência e interagir com os telespectadores. Essa pesquisa traz uma análise comparativa de alguns desses apps com o objetivo de apontar diretrizes para a criação de um modelo de segunda tela voltado para o jornalismo. Os aplicativos Globo, Superstar, Tomara que Caia e The Voice Kids foram testados com o público a fim de identificar as funções que mais se destacavam. Com base nas respostas obtidas, juntamente com o desenvolvimento teórico desse trabalho, são propostas funções a serem exploradas em um app jornalístico de segunda tela.
Abstract : Studies published by Ibope (2012), Google (2013) and Nielsen (2015) shows that much of the population has become accustomed to using a mobile device while watching TV, and also to comment on social networks about the program watched. This phenomenon has been termed as Social TV, and the platform on which it occurs, as a second screen. Observing this trend of public, broadcasters launched applications to stimulate the audience and interact with viewers. This research provides a comparative analysis of some of these apps in order to point out guidelines for the creation of a second- screen app to journalism. The applications Globo, Superstar, Tomara que Caia and The Voice Kids were tested with the public to identify the features that most stood out. Based on the responses, along with the theoretical development of this work, are proposed functions to be explored in journalism second screen app.

A pesquisa investiga, de forma prático-teórica, o processo de confecção de objetos cerâmicos, enquanto signos de uma linguagem visual universal, através da qual o homem se encanta e canta sua concepção de universo. Uma linha imaginária visualsonora,portanto, liga o procedimento cerâmico que se faz com terra — argila — ao planeta Terra, considerando fazeres poéticos regionais e universais. Esta linha tornase eixo da imaginação para o movimento incessante entre cosmovisões ameríndias e devaneios contemporâneos. Enquanto as experimentações cerâmicas tornam-se sementes, proto-estrelas e outras formações cósmicas, constelações de obras-estrelas são traçadas para visualizar e analisar o gesto criativo por método associativo e processual como em redes de criação. Tomo Gaston Bachelard como filósofo norteador desta pesquisa porque é esclarecedora sua análise da ação do modelador,daquele que, com imaginação e vontade, trabalha com a maciez e resistência das massas cerâmicas. Faço aproximações e distanciamentos com obras de artistas pesquisadores nas áreas de artes visuais e música: Norma Grinberg, Eriel Araújo,Ana Maria Tavares, Walter Smetak, Susan Rawcliffe, Márcia Xavier, Gabriel Orozco,Amélia Toledo, Celeida Tostes e Delma Godoy. As reflexões e a prática no atelier apontaram caminhos e possíveis respostas para questões que envolvem o procedimento cerâmico e a arte contemporânea. Os resultados que abraçam o diálogo com o espectador para conquista de novos conhecimentos, interligados a esta dissertação, foram apresentados em duas exposições individuais: Germinando Estrelas, onde foram instalados objetos sonoros, as Proto-estrelas, na EBEC Galeria de Arte, em 2007, e terra-Terra, onde se pode perceber uma atmosfera cósmica com as obras Granulações, Sítio cósmico, Proto-estrelas, Cantos do joão-de-barro e Caco-cipó no sótão do Palacete das Artes Rodin Bahia, em 2009, em Salvador.

A stochastic dynamic programming model (called P.B.S.D.P.) based on the consideration of peak discharge and time between peaks as two stochastic variables has been used to model and to solve a reservoir operation problem. This conceptualization of the physical reality allows to solve, in this order, the tactical and strategic operation of surface reservoirs. This P.B.S.D.P. model has been applied to the Sau reservoir in the Northeastern corner of Spain. The results showed a significant improvement over the currently used operation procedure, yielding values of yearly average electricity production that are somewhat under 6% of what could have been the maximum electricity production.

Under lärarutbildningens gång har vi kommit i kontakt med och intresserat oss för den tematiska undervisningsmetoden. Vi har bland annat stött på metoden ute på fältet och genom inriktningen språk och skapande.
Huvudsyftet med denna uppsats är att undersöka den tematiska arbetsmetodens kvalitet. Målsättningen är att studera den tematiska arbetsmetoden och undersöka om det är en metod som kan gynna alla elever, oavsett inlärningsförmåga, intressen och förkunskaper. Frågeställningarna som vi belyser är om den tematiska undervisningen är en metod som är lämplig för alla elever och pedagoger, varför man ska använda sig av den tematiska undervisningen istället för den traditionella, samt vilka för- och nackdelar som det finns med tematiskt arbete.
Vi har använt oss av en kvalitativ undersökningsmetod och därmed intervjuat fem pedagoger som arbetar med den tematiska arbetsmetoden på olika sätt. Svaren har sammanställts och jämförts med relevant litteratur.
Vi har belyst och kommit fram till att den tematiska arbetsmetoden är en metod som kan gynna alla elever, med varierande inlärningsmöjligheter, intressen, förkunskaper och ålder. De pedagoger vi har intervjuat har varit mestadels positivt inställda till den tematiska undervisningsmetoden.

Overtidig svangerskap er å betrakte som et risikosvangerskap. Studier har vist at det ved overtid er økt risiko for død i mors mage og i nyfødtperioden. I mange land settes derfor fødselen i gang en uke etter at terminen er passert, men i Skandinavia er det tradisjon for å la svangerskapet fortsette 2-3 uker etter at terminen er passert. Studier har vist at det å sette fødselen i gang også er forbundet med komplikasjoner for mor og barn. Behandlingen av det ellers ukompliserte overtidige svangerskap er kontroversiell.
Avhandlingen består av 4 delstudier.
I den første studien undersøkte vi hvordan det gikk med mor og barn i forhold til hvilken svangerskapsuke fødselen skjedde. Vi undersøkte også om det var forskjellige resultater for mor og barn om fødselen startet av seg selv eller ble igangsatt. Alle kvinner som fødte etter 37. svangerskapsuke ved St.Olavs Hospital i perioden 1990-2001 ble inkludert. Resultatene viste at komplikasjoner hos mor varierte med svangerskapslengden, og var lavest en uke før termin og høyest når svangerskapet var overtidig. Komplikasjoner for barnet varierte med svangerskapslengde bare hvis fødselen startet av seg selv. Igangsetting av fødsel var en risiko for komplikasjoner uavhengig av svangerskapslengde.
Den andre studien sammenlignet sykelighet hos barna og komplikasjoner hos mor hvis fødselen ble satt i gang en uke over termin eller svangerskapet ble kontrollert hver 3. dag til hun var nesten 3 uker over terminen. Kvinnene trakk lodd om hvilken gruppe de skulle komme i, og til sammen deltok 508 kvinner. Sykeligheten hos barna var den samme i begge grupper. Det var flere raske fødsler i gruppen som fikk fødselen igangsatt, men det var det ingen forskjell på forekomsten av komplikasjoner mellom gruppene. Keisersnittfrekvensen var lav.
Kvinnene som deltok i den andre studien ble intervjuet om sitt syn på overtidig svangerskap når de ble inkludert. Dette ble gjentatt 6-8 måneder etter fødselen, og de ble da også spurt om hvilke erfaringer de hadde gjort seg og hvordan de ønsket å bli fulgt opp i et evt. fremtidig overtidig svangerskap. En uke over termin svarte 74% at de ønsket å få fødselen igangsatt. De fleste (84%) som fikk fødselen igangsatt rapporterte at dette var en positiv opplevelse, og 74% ønsket å bli igangsatt hvis de skulle bli overtidige i et fremtidig svangerskap. Bare 38% av de som kom i ventegruppen ønsket å vente. I gruppen som ble igangsatt var det flere raske fødsler, og kvinnene anga at riene var mer intense og hyppige i denne gruppen sammenlignet med ventegruppen.
I den siste studien så vi på data fra Medisinsk Fødselsregister for alle fødsler etter 41 uker i Norge i perioden 1999-2005. Vi ønsket å studere forekomsten av fosterdød i mors mage og død i tidlig nyfødtperiode og regne ut hvor mange fødsler man måtte sette i gang for eventuelt å unngå 1 dødsfall. Forekomsten av dødsfall var lav, men økte med svangerskapslengden. Ved uke 41 må man sette i gang > 500 fødsler for å unngå 1 dødsfall, ved uke 43 < 200. Hvis vi i Norge skal sette alle fødsler i gang ved 41 uker, vil dette medføre > 14.000 igangsettinger i året.

Full textAbstract:
“Jarðnæði; Tranquil Terra” is a meditation on the relationship between the dwelling and the dramatic ever-changing landscapes of the rural Icelandic countryside. The project is anchored in a place with a long and complex history and with a profound relationship with its landscapes - a place of wandering churches, lifesaving shipwrecks, growing houses, teeth in the ground, paths lined with crosses to protect against the ghosts and other dark creatures. It is a place where everything is vibrant, alive and has a story to tell. In the journey to the Tranquil Terra I navigated by means of cartography and critical fiction in search of ways to rethink the Icelandic architectural heritage beyond the nature-culture divide."Jarðnæði; Tranquil Terra " är en meditation över förhållandet mellan bostaden och det ständigt föränderliga landskapet på den isländska landsbygden. Projektet är förankrat i en plats med en lång och komplicerad historia och med en djup relation med sitt landskap - en plats för vandrande kyrkor, skeppsvrak, växande hus, vägar kantade med kors för att skydda mot spöken och andra skrämmande varelser. Det är en plats där allt är levande och har en historia att berätta. I resan till Tranquil Terra navigerade jag med hjälp av kartografi och kritisk fiction på jakt efter ett nytt sätt att tänka kring det isländska arkitektoniska arvet utöver klyftan mellan natur-kultur.

Denna uppsats behandlar arbetet med tema. Betecknande för temaarbete är bland annat dess obundenhet från traditionella läromedel. Inom det tematiska arbetet finns en röd tråd, och elevernas förkunskaper tas tillvara. Det som har studerats är hur lärarna arbetar med tema och hur de tar tillvara på elevernas erfarenheter och förkunskaper samt vilket inflytande eleverna har enligt lärarna och eleverna själva. Detta har studerats i två olika klasser med hjälp av observationer och intervjuer med lärare och elever. Teorier som stärker vårt empiriska material är litteratur som är kopplat till tematiskt arbete och elevinflytande. Uppsatsen bygger till stor del på en observation med den ena klassen där de hade en temautflykt. Vi har därför inte studerat tema generellt utan istället fördjupat oss i två olika teman, ”Fåglar” och ”Sverige/Norden”. I arbetet har tema ”Fåglar” en mer framträdande roll än ”Sverige/Norden”. Vi har också genomgående diskuterat val av tema, den tematiska arbetsprocessen och elevinflytande i detta. Det som bland annat kommit fram ur forskningen är att eleverna har ett begränsat inflytande och att temavalet styrs av lärarna, som i sin tur enligt dem styrs av läroplanen.

Artist Statement My landscapes depict the converging of sky, water, and land to symbolize transcendence, transformation, and life. I use an impressionistic style and manipulate the effects of light to capture a scene as it appears to me. Other times I re-arrange sky, land, and water into compositions that I visualize in my imagination. The convergence of natural elements can be a wide open gate where the ocean meets the sky, or it can be the narrow meandering path of a long river that meets the sky at a distant horizon. I use the physicality of terra firma, the place I inhabit physically and spiritually, as I use my art to describe the signs of transcendence and transformation.

A presente dissertação analisa a estrutura de telejornais dos países do Rio de la Plata, partindo da noção de estrutura, como organização espaço-temporal do produto jornalístico e de seu processo de produção. A pesquisa apóia-se num estudo de caso múltiplo, cujo objeto são os telejornais Telemundo Edición Central, do Canal Teledoce, do Uruguai, e Telenueve 2ª Edición, do Canal 9, da Argentina. Para esta análise, foi desenvolvida uma metodologia, com o intuito de examinar de forma integrada o plano da imagem, o plano sonoro e sua combinação audiovisual. Como forma de explicar alguns aspectos da estrutura do produto, realizaram-se, também, observação do processo de produção e entrevistas com profissionais das equipes de cada telejornal. A contribuição deste trabalho está em demonstrar como países cultural e geograficamente tão próximos podem produzir telejornais bastante diferentes.
This dissertation analyzes the structure of the TV newscast of Rio de la Plata countries. Part of the concept of structure as an organization of space-time journalistic product and its production process. The research is based on a multiple case study, having as object the TV newscasts Telemundo Central Edition, on Channel Teledoce, Uruguay, and Telenueve 2nd Edition on Channel 9, Argentina. In order to examine with an integrated view the plan of the picture, the plan of the sound and their audiovisual combination we developed specific methodology. As a way to explain some aspects of the structure of the product, an observation of the production process and interviews with professional teams in each of the TV newscast, was also made. The contribution of the work is to demonstrate how two countries culturally and geographically close can produce quite different television newscasts.

A pesquisa trata da educação rural no Brasil num contexto histórico marcado pela predominância da população rural (1910-1961), explicitada por meio do pensamento de Antônio Carneiro Leão. Embora partindo do contexto brasileiro, traz para o debate contribuições do pedagogo português António Sérgio, referentes a um período contemporâneo. O estudo desenvolveu uma análise sobre a educação rural, discutindo a função social da escola, tomando como referência exemplos de sua institucionalização para os imigrantes poloneses e seus descendentes no Brasil. Tal objetivo geral está desdobrado nos seguintes objetivos específicos: identificar concepções político-pedagógicas sobre educação rural, notadamente as apresentadas por Carneiro Leão e António Sérgio; identificar e caracterizar as interlocuções entre o pensamento de Antônio Carneiro Leão e António Sérgio no que tange à educação rural; problematizar o sentido da escola para os imigrantes poloneses no contexto da educação rural no Brasil; caracterizar, no processo histórico, a criação e a permanência do ?amor à terra? enquanto estrutura de sentimento. Quanto à metodologia elegida, consiste em uma pesquisa documental. Está embasada nas obras de Carneiro Leão: ?O Brazil e a educação popular? (1917), ?A sociedade rural: seus problemas e a sua educação? (1939), ?O sentido da evolução cultural no Brasil? (1946), a segunda edição de ?Fundamentos de sociologia? (1954) e ?Panorama sociológico do Brasil? (1958); nas obras de António Sérgio: ?Da natureza da afecção? (1913), ?Educação cívica? (1915) e ?Manual de instrução agrícola na escola primária? (1916); e na obra de John Dewey, ?Democracia e educação? (1916). Para efeito de análise, adotamos o conceito de ?estrutura de sentimento? de Raymond Williams (1979). Constatamos a construção histórica de estruturas de sentimento que denominamos ?amor à terra?, por meio da produção de culturas emergentes, dominantes e residuais, explicitadas pelo pensamento de Carneiro Leão e de António Sérgio quanto à educação rural. Identificamos também a formação da estrutura de sentimento ?amor à terra? como uma hipótese cultural explicativa alicerçada pelo processo de instituição da escola no meio rural brasileiro e, particularmente, no cenário da imigração polonesa. Foi possível estabelecer relações entre o ruralismo expresso no pensamento de Carneiro Leão e António Sérgio e perspectivas teóricas da Escola Nova, notadamente em relação a concepções de Dewey presentes na obra ?Democracia e Educação?. Em suma, tais constatações nos possibilitam defender, ao longo da história, o processo de elaboração de uma estrutura de sentimento denominada de ?amor à terra?, nutrida pelo ruralismo pedagógico, pela experiência social e tradição presentes na formação cultural do meio rural, que se manifestaram em culturas, ora emergentes, ora dominantes ou residuais, como estágios que se movimentam e oscilam em diferentes espaços geográficos.
Abstract : The research deals with rural education in Brazil in a historical context marked by the predominance of the rural population (1910-1961), made explicit by the thought of Antônio Carneiro Leão. Although starting from the Brazilian context, brings to the debate contributions of the Portuguese pedagogue António Sérgio, referring to a contemporary period. The study developed an analysis of rural education, discussing the social function of the school, taking as reference examples of school for Polish immigrants and their descendants in Brazil. This general objective is subdivided into these specific objectives: to identify political-pedagogical conceptions about rural education especially those presented by Carneiro Leão and António Sérgio; to identify and to characterize the interlocutions between the thought of Antônio Carneiro Leão and António Sérgio in rural education; to problematize the sense of school for Polish immigrants in the context of rural education in Brazil; to characterize, in the historical process, the creation and permanence of the ?love the countryside" as a structure of feeling. The methodology consists of a documentary research. The books of Carneiro Leão are ?O Brazil e a educação popular? (1917), ?A sociedade rural: seus problemas e a sua educação? (1939), ?O sentido da evolução cultural no Brasil? (1946), the second edition ?Fundamentos de sociologia? (1954) and ?Panorama sociológico do Brasil? (1958); the books of Antonio Sérgio are ?Da natureza da afecção? (1913), ?Educação Cívica? (1915) and ?Manual de instrução agrícola na escola primária? (1916); and book of John Dewey is ?Democracy and education? (1916). For analysis of the books, we adopted ?feeling structure? concept of Raymond Williams (1979). We verified in the historical construction of structures of feeling that we call "love the countryside", through the production of emergent, dominant and residual cultures that appear thought of Carneiro Leão and António Sérgio on rural education. We also identify the formation of the "love the countryside" feeling structure as a cultural hypothesis explained by the educational process of the school in the rural Brazilian and particularly, in the Polish immigration. It was possible to establish relationships between the pedagogical ruralism that appeared in the thought of Carneiro Leão and António Sérgio and with theoretical perspectives of the New School, notably in the Dewey conceptions present in the book "Democracy and Education". Finally, these findings allow us to defend during the historical period, the process of elaborating a structure of feeling called "love the countryside" developed by pedagogical ruralism by the experience and social tradition present in the cultural formation in the rural environment, that appeared in the cultures as emergent, dominant or residual that move and oscillate in different geographic spaces.

Full textAbstract:
How do we learn a sequence of items so we can remember it not only over the short-term, as in hearing a phone-number and repeating it back, but over the long term? Ten experiments are presented that investigate this problem using the Hebb repetition effect (Hebb, 1961). In a canonical Hebb effect experiment, lists of familiar items are presented in an immediate serial recall task and one list is repeatedly presented at regular intervals. This leads to an improvement in recall for the repeating list over baseline performance. Existing models of serial order learning are tested; Chapter 2 provides evidence contrary to positional models of the Hebb effect while Chapter 5 provides evidence against chaining models. The experiments in these chapters (Experiments 1, 2 and 7) use a transfer design where a representation of the repeating list (Hebb list) is built up, then a list is presented whose structure is derived from the Hebb list in a way that tests the predictions of these models. The experiments of Chapters 4 and 5 examine the hypothesis that the most parsimonious model of the Hebb effect is one that is based on the formation of chunks (Miller, 1956), higher-level representations of several items. The results of these experiments are consistent with a chunking model based on the Primacy model (Page and Norris, 1998), but do not provide direct evidence of a chunking process. A growing body of evidence (e.g. Baddley et al., 1988; Papagno et al., 1991) suggests that the phonological store of the working memory model (Baddeley, 1986) plays an important role in the development of long term representations required for the acquisition of new vocabulary. For example, the ability to learn new words is impaired in patients with damage to the phonological store (e.g. PV, SC) and in normal subjects performing articulatory suppression. In chapter 6, the hypothesis that the Hebb effect is an experimental analogue of phonological form learning is investigated, the results of which suggest that the Hebb effect is involved in at least some of the same processes.

The purpose of this thesis was to investigate the factors affecting the retention behavior of first term and second term Marine Corps enlisted members. Data were extracted from the 1992 DoD Survey of Officer and Enlisted Personnel and their Spouses and were matched with the respondents' 1996 status from the Active Duty Military Master and Loss File by the Defense Manpower Data Center. The sample was restricted to Marines with between two and ten years-of- service who had less than two years remailing on their enlistment contract and was further stratified by term of enlistment and gender. A complete conceptual model was developed which incorporated individual and organizational factors affecting retention. Four categories of determinants of turnover were used: Demographic, Military Experience, Cognitive and External. Logistic regression was used to measure the relative importance of a broad range of these factors for the retention decision. Results indicated that the factors affecting retention differ across term of service and by gender. No single factor was significant for all gender/term of service samples. Some factors were significant only for a particular term of service. Others were significant only by gender and many were significant only for a single sample. The specific findings can provide manpower planners with targeted information to manage retention levels for first term and second term Marines more effectively

Full textAbstract:
The aim of this thesis is to forecast passenger demand in long term and short term perspectives at the Airport of Bologna, a regional airport in Italy with a high mix of low cost traffic and conventional airline traffic. In the long term perspective, time series are applied to forecast a significant growth of passenger volumes in the airport in the period 2016-2026. In the short term perspective, time-of-week passenger demand is estimated using two non-parametric techniques; local regression (LOESS) and a simple method of averaging observations. Using cross validation to estimate the accuracy of the estimates, the simple averaging method and the more complex LOESS method are concluded to perform equally well. Peak hour passenger volumes at the airport are observed in historical data and by use of bootstrapping, these are proved to contain little variability and can be concluded to be stable.Målet med denna uppsats är att prognosticera passagerefterfrågan i lång- och kortsiktigt perspektiv på Bologna Flygplats, en regional flygplats i Italien med hög mix av lågkostnadsbolag och konventionella flygbolag. I det långsiktiga perspektivet appliceras en tidsseriemodell som prognosticerar hög tillväxt i passagerarvolymer på flygplatsen under perioden 2016-2026. I det korta perspektivet uppskattas efterfrågan utefter tid i veckan med hjälp av två icke-parametriska modeller; local regression (LOESS) och en simpel metod som beräknar medelvärdet utav observationer. Med cross validation uppskattas precisionen i modellerna och det kan fastställas att den simpla medelvärdesmetoden och den mer avancerade LOESS-metoden har likvärdig precision. Passagerarvolymer på flygplatsen under högtrafik observeras i historisk data och med hjälp av bootstrapping visas att dessa volymer har låg variabilitet och det kan fastställas att de är stabila.

Resumo: Esta pesquisa tem como finalidade refletir sobre as condições pelas quais, nos séculos XIX e XX, a Ciência e a Técnica foram colocadas na cultura como desafios à criatividade pictórica. A resposta manifesta-se, na pintura, como anseios que procuram alcançar os ideais das atividades predominantes da cultura dessa época. Com o aparecimento das Novas Tecnologias da Comunicação, especificamente da imagem digital, realizam-se alguns princípios que a atividade pictórica apontava como anseios. Este processo aparece também com a Estética e a Estética Informacional, a qual coloca a possibilidade da objetivação da arte. O trabalho foi estruturado a partir de quatro problemas identificados como anseios. O primeiro referido à Estética, analisa o percurso que esta faz para estabelecer um diálogo com a Ciência. O segundo, mostra como nos séculos XIX e XX, o ofício artístico assimila no processo criativo a Ciência e a Técnica. O terceiro localizado no século XX, explica a maneira como diversas máquinas (com ênfase no computador) são usadas para alcançar os anseios de movimentação e luminosidade colocados como problemas da pintura. O quarto relaciona a desmaterialização da imagem digital, com um anseio da pintura que procurava esta diluição da matéria

The purpose of this investigation was to test the theoretical possibility of an investor earning a positive cash return from the activities of the stock market despite effectively holding no position at all in said market. The sample data were the daily returns for the shares of the 780 companies listed on the NASDAQ and the New York Stock Exchange (“NYSE”), which fell within the top 500 listed companies by market capitalisation between 1 January 2005 and 31 December 2017. The reversal strategy’s performance was evaluated using portfolios constructed as quantiles of 100 or 500 shares, respectively, where the investor had the option of implementing the reversal strategy immediately after an information-gathering period closed or a day thereafter. The time intervals used were 1 January 2005 to 29 September 2008 (the day the Dow Jones Industrial Average crashed by 777.68 points), 29 September 2008 to 31 December 2017 and 1 January 2005 to 31 December 2017. Of the 1000 portfolios tested in each time interval, at least 416 had positive average returns in every time interval. Of the portfolios that had positive average returns over the time intervals, at least 66 had statistically significant average returns in every time interval. The best-performing portfolio for the entire sample period was a combination of the best-performing pre-crash and post-crash portfolios - an investor who held that portfolio realised a cumulative return of approximately $61.39 for every $1 invested. The conclusion was that it was theoretically possible for an investor to earn a positive cash return from the market’s activities despite effectively holding no position at all in the market. Consequently, it was concluded that the strong form of Fama’s (1970) Efficient Market Hypothesis was disproved. Future research should include out-of-sample tests, tests that include restrictions on short selling and tests that consider the impact of trading costs on portfolio performance, to render the conclusions of this investigation more practically applicable to investors.

Full textAbstract:
The electric power industry is undergoing a restructuring process. The major goals
of the change of the industry structure are to motivate competition, reduce costs and
improve the service quality for consumers. In the meantime, it is also important for the
new structure to maintain system reliability. Power system reliability is comprised of
two basic components, adequacy and security. In terms of the time frame, power system
reliability can mean short-term reliability or long-term reliability. Short-term reliability
is more a security issue while long-term reliability focuses more on the issue of
adequacy. This dissertation presents techniques to address some security issues
associated with short-term reliability and some adequacy issues related to long-term
reliability in deregulated power systems.
Short-term reliability is for operational purposes and is mainly concerned with
security. Thus the way energy is dispatched and the actions the system operator takes to
remedy an insecure system state such as transmission congestion are important to shortterm
reliability. Our studies on short-term reliability are therefore focused on these two
aspects. We first investigate the formulation of the auction-based dispatch by the law of
supply and demand. Then we develop efficient algorithms to solve the auction-based
dispatch with different types of bidding functions. Finally we propose a new Optimal
Power Flow (OPF) method based on sensitivity factors and the technique of aggregation
to manage congestion, which results from the auction-based dispatch. The algorithms
and the new OPF method proposed here are much faster and more efficient than the
conventional algorithms and methods. With regard to long-term reliability, the major issues are adequacy and its
improvement. Our research thus is focused on these two aspects. First, we develop a
probabilistic methodology to assess composite power system long-term reliability with
both adequacy and security included by using the sequential Monte Carlo simulation
method. We then investigate new ways to improve composite power system adequacy in
the long-term. Specifically, we propose to use Flexible AC Transmission Systems
(FACTS) such as Thyristor Controlled Series Capacitor (TCSC), Static Var
Compensator (SVC) and Thyristor Controlled Phase Angle Regulator (TCPAR) to
enhance reliability.
