El objetivo es competir en el segmento especializado High/Super Premium de alimentos para perros y gatos en Chile - el cual utiliza como canales de distribución preferente las veterinarias, pet shops y criadores- con las marcas Techni-cal y Doc Kennedy, marcas importadas provenientes de orígenes con altas tecnologías de fabricación, experiencia y prestigio en la fabricación de alimentos para mascotas. Se considera que en Chile existen grandes oportunidades de inversión para los productos mencionados, sólo en los últimos 4 años el negocio de los animales domésticos ha tenido un crecimiento del 37%. Además existen clientes cada vez más exigentes, dispuestos a pagar más por la calidad de los alimentos para sus mascotas. Aun cuando Sumitomo comenzó a participar en este mercado y segmento hace algunos años, su participación es muy baja comparado con el crecimiento que ha tenido el mercado en general debido a la ausencia de una estrategia de marketing, su participación total de 3%, con ventas anuales de $350 millones y un margen de utilidad bruta de $80 millones. El siguiente plan está enfocado en la creación de un plan de marketing para la división alimento para mascotas con la finalidad de lograr el tamaño exigido por la compañía, el cual establece que cada negocio en el cual tiene presencia debe generar sobre $250 millones de Utilidad Bruta. Con el desarrollo de este plan, estimamos sobrepasar esa cifra al quinto año.

Full textAbstract:
Increases in human population and activities have lead to significantly enhanced inputs of carbon and nitrogen fiom both point and difiuse sources to rivers, estuaries, and coastal seas, altering the global carbon and nitrogen biogeochemical cycles. This increased load has had a marked ecological impact globally, with detrimental changes to primary production, conununity stricture and water quality. Understandmg the nature and cycling of dissolved organic carbon (DOC) and nitrogen (DON), significant components of the global carbon and nitrogen cycles, in estuaries will provide better estimates of C and N transport to coastal and ocean waters. This study involves: (1) optimisation of the h i ^ temperature catalytic oxidation (HTCO) analytical method used for reliable analysis of DOC and total, dissolved nitrogen (TDN), (2) investigation of spatial and temporal variations of DOC and DON, and other reliated determinands, in two contrasting estuarine environments, the Yealm and Plym, in south-west England, (3) investigation of DON bioavailability using a bacterial incubation experiment, and (4) preliminary work on the use of stable nitrogen isotope ratios to identify DON sources. The sampling and analytical protocols required for rapid, precise and reliable determinations of DOC and DON, using the coupled HTCO-chemiluminescence technique, are described ui this study. This metiiod gave detection limits of approxunately 6.2 \iM C and 0.46 | iM N , and precisions of < 2-3 % and < 3-5 % (n=3-5) for DOC and TDN, respectively. The mean DOC and TDN of the CRMs analysed, over a period of 2 years, were 48 ± 3.9 | iM C and 20 ± 1.5 nM N that were close to the certified values of 44 - 45 pM C and 21 | iM N , respectively. Concentrations of DOC ranged from 61 | iM C at the seaward end to 335 pM C at the fresh water end for the Yealm, and 71 - 290 |j,M C for the Plym. DON concenfrations were mamly m the range of 1.8 - 62 pM N for the Yeahn, and 4-94 \iM N for the Plym. The enhanced DON concenfrations in the Yealm might be the result of sewage discharges and agricultural run off, while in the Plym they may be due to sewage discharge, run off from the Chelson Meadow landfill and other anthropogenic activities within the urban Plym catchment. Except during a limited numbers of surveys, DOC and DON generally behaved in a non conservative manner in these estuaries. Nifrate and filterable reactive phosphate (FRP) behaved relatively conservatively m the Yealm, but were more non-conservative in the Plym. The spatial distribution of DOC and DON concenfrations in the Plym Estuary appeared much more mfluenced by anthropogenic uiputs relative to distributions in the Yealm Estuary. The seasonal variation of DOC and DON was characterised by lower concenfrations during winter and a slight increase in spring and suimner followed by highest concenfrations during late smmner and auturrm, suggesting a sfrong link to seasonally variable phytoplankton production. The confribution of DON to die TDN pool ranged between 4 and 79 % for the Yealm, and 3.5 - 84 % for the Plym. Higher values (53 - 79 %) were observed during late summer, emphasising the important contributions of DON to TDN- pool. Incubation experiments usmg the Plym Estuary water mdicated that 30 - 58 % of DON was bioavailable for heterofrophic bacterial utilisation; at the same time nitrate concentrations increased by 9 - 35 %, presumably through mineralization of DON. From the studies undertaken in the present work, it may be concluded that the omission of DON in estuarine and coastal water studies will result in underestimation of the total nifrogen load. As a significant part of the DON appeared to be bioavailable, ignoring this fraction will result in an underestimation of eutrophication pressures on coastal and ocean waters.

Zhang, Zhuoli. "Dissolved organic carbon (DOC) management in peatlands." Thesis, Durham University, 2015. http://etheses.dur.ac.uk/11357/.
Full textAbstract:
Peatlands are serving as one of the most important terrestrial carbon stores in the United Kingdom and globally. In the UK, the current trend of peatlands turning from carbon sinks to carbon sources is widely observed and reported. As numerous factors may affect the carbon cycle of peatlands, including climate, land management, hydrology and vegetation, dissolved organic carbon (DOC) was commonly used as an indicator of peatland carbon changes. Besides the function as an indicator of carbon turnover in peatland, increasing DOC in the stream water also raises concern in water companies as the removal of DOC from water represents a major cost of water treatment. This thesis investigates the impacts of land management such as drain blocking and revegetation on stream DOC changes. By building a pilot column study, this thesis also assessed the potential of bank filtration serving as DOC treatment in UK. Results of drain blocking shows the management was a significant impact on the DOC changes. However, later investigation of peak flow events indicates such positive impacts from drain blocking were minor in terms of high peak flow events. Since the majority of DOC export occurred during such peak flow events, drain blocking were found not as an efficient management of DOC changes. The field study of revegetation observed minor effects of revegetation on stream DOC. The results of column bank filtration indicate low DOC removal rate under the current stream DOC level in UK. The bank filtration may efficient remove DOC when higher DOC input applied. However, it is not suitable for UK peatland under current DOC export.

La cultura de prevención médica ante posibles enfermedades a la salud es un tema en el que la población peruana todavía no toma conciencia. Muchos peruanos sólo acuden a hospitales o clínicas cuando les duele una parte del cuerpo o sienten que ya deberían de tratarse. Por otro lado, el obtener una cita médica con el especialista suele demorar varios días o incluso meses, en donde el paciente no tiene una solución rápida para calmar ese mal que le aqueja.
A raíz de la pandemia actual, la obtención de estas citas se ha dilatado o incluso se han priorizado especialidades médicas por otras, esto ha generado la saturación en el sistema de salud. Se ha encontrado como oportunidad de negocio la creación de un aplicativo móvil denominado “Mi Doc” que cumpla la función de ser un intermediario entre el paciente y consultorios independientes (doctores), con la finalidad de reservar citas médicas en donde el usuario podrá elegir la programación de la cita según su disponibilidad, cercanía y precio.The culture of medical prevention in the face of possible diseases is a topic that the Peruvian population is not yet aware of. Many Peruvians only go to hospitals or clinics when they are in pain or feel they should be treated. On the other hand, obtaining a medical appointment with a specialist usually takes several days or even months, where the patient does not have a quick solution to calm this disease that afflicts him. Due to the current pandemic, obtaining these appointments has been delayed or even prioritized by other medical specialties, which has generated saturation in the health system. A business opportunity has been found in the creation of a mobile application called "My Doc" that serves as an intermediary between the patient and independent practices (doctors), to book medical appointments where the user can choose the scheduling of the appointment according to availability, proximity and price.

The following research has examined the assessment of issues relating to the consumption of CDO (Controlled Denomination of Origin) Colli Euganei (CE) wine in a sample of restaurants of the Padua province. 63% of operators said they always have a minimum number of references of CE denomination as the Fior d’Arancio.
The number of references of these wines increases with the average meal price of, indicating that they are more frequent in restaurants showing a certain quality level. Moreover, their average selling price does not differ from the values recorded for other types of wine, though it tends to be lower. The manager or sommelier make the choice of CDO wines on the basis of personal opinions and customer requirements. The purchase of the Doc EC is often done by dealing directly with the producer: this is a further evidence of the strong linkage with the Padua land. We found that the food and wine events, often carried out in collaboration with the Consortium, create a direct contact between the restaurateur and vintner. leading to a consequent increase in purchasing; and this fact is anyway supported by the quality and ease of the product. However, competition from other wine, driven by distribution operators, is remarkable.La seguente ricerca ha preso in esame la valutazione degli aspetti relativi al consumo di vino Doc Colli Euganei presso un campione di ristoranti padovani.

Le referenze di questi vini aumentano all’aumentate del prezzo medio del pasto, indice che sono anche presenti in ristoranti di un certo livello qualitativo. Inoltre, il loro prezzo medio di vendita non si discosta dai valori registrati per le altre tipologie di vino, anche se tendenzialmente tende a essere più basso. Il gestore o il sommelier effettuano la scelta del vino a denominazione sulla base delle personali opinioni e sulle richieste del cliente. L’acquisto del vino Doc C.E avviene spesso tramite un contatto diretto con il produttore; a conferma della maggior frequenza di consumo nel territorio padovano. E’ così stato riscontrato che le manifestazioni enogastronomiche, spesso effettuate in collaborazione con il Consorzio, creano un contatto diretto tra il ristoratore e il vitivinicoltore portando ad un conseguente incremento degli acquisti; ciò è comunque supportato dalla qualità e dalla facilità del prodotto. Tuttavia, la concorrenza degli altri vini, proposta dalla distribuzione, è notevole.

The climate change is expected to affect especially alpine areas negatively, replacing the alpine flora with subalpine forest. The understanding of how vegetation influences total organic carbon (TOC) in soil, streams and lakes in alpine and subalpine areas will lead to a better understanding of the effects of climate change, and will also increase the knowledge of the ecotone as a whole. In this study plant-soil relations were examined in a subalpine and an alpine catchment in the north of Sweden, by comparing dissolved organic carbon (DOC) concentrations, 13C-DOC, 13 compared with lake and stream water DOC, as well as sediment OC from the recipient lakes in the catchments.

Full textAbstract:
When plants and animals die they are decomposed into microscopic particles of organic carbon. In the ground, these carbon particles are dissolved in the soil water and eventually transported to the streamchannel with the flow of the groundwater. Today the quantities of dissolved organic carbon (DOC) have been observed to increase in many lakes and streams around the world, which constitute a threat against the water quality and ecologic environment of these surface waters. The amount of organic carbon that is dissolved and transported in the soil water is mainly controlled by processes related to temperature and hydrology, two factors which vary seasonally. Because of difficulties to sample soil water at temperatures below 0°C studies of DOC transport between soil and water during the winter season are limited. This study therefore conducted a winter sampling of soil water, with the focus on DOC. Samples were collected in March 2014 at sites along three hillslopes, orthogonal to two streams, in a typical Swedish boreal forest northwest of Umeå. The soil water was extracted with the help of suction lysimeters installed at different depths in the soil, and heating equipmentpowered by batteries. The collected samples were analyzed for DOC concentration and absorbance after which the results were grouped together with results from previous sampling campaigns, conducted in the summer and autumn of 2013. Parallel to this, data representing a longer time series (2009 to 2012) at another hillslope was processed. During the summer and autumn an increase in DOC concentration was observed. The increase was assumed to be caused by high production and effective degradation of organic matter in the soil during this warm period. Generally, a decrease in the DOC concentration then followed during the winter season. One possible reason for this decrease could be that the bacterial degradation in the soil continued, during the winter, and transformed the dissolved carbon into CO2 and CH4. Another possibility is that the DOC was flushed into the streams by autumn rain events. The study also found differences concerning the DOC concentration and character in the soil water, as well as the seasonal variation of these parameters, with soil depth and distance from the stream along the hillslope profile. These differences could be correlated to the organic content of the soil, from which the soil water had been extracted.

Full textAbstract:
Of the organic matter in soils typically < 1% by weight is dissolved in the soil solution (dissolved organic matter; DOM). DOM is a continuum of molecules of various sizes and chemical structures which has largely been operationally defined as the fraction of total organic carbon in an aqueous solution that passes through a 0.45 µm filter. Although only representing a relatively small proportion, it represents the most mobile part of soil organic carbon and is probably enriched with highly labile compounds. DOM acts as a source of nutrients for both soil and aquatic micro-organisms, influences the fate and transport of organic and inorganic contaminants, presents a potential water treatment problem and may indicate the mobilisation rate of key terrestrial carbon stores. The objective of this research was to ascertain some of the biologically relevant characteristics of soil DOM and specifically to determine: (1) the influence of method and time of extraction of DOM from the soil on its biochemical composition and concentration; (2) the dynamics of DOM biodegradation; and, (3) the effects of repeated applications of trace amounts of DOM on the rate of soil carbon mineralization. To examine the influence of method and time of extraction on the composition and concentration of DOM, soil solution was collected from a raised peat bog in Central Scotland using water extraction, field suction lysimetry, and centrifugation techniques on a bimonthly basis over the period of a year (Aug 2003 – Jun 2004). Samples were analysed for dissolved organic carbon (DOC), dissolved organic nitrogen (DON), protein, carbohydrate and amino acid content. For all of the sampled months except June the biochemical composition of DOC varied with extraction method, suggesting the biological, chemical and/or physical influences on DOC production and loss are different within the differently sized soil pores. Water-extractable DOC generally contained the greatest proportion of carbohydrate, protein and/or amino acid of the three extraction methods. Time of extraction had a significant effect on the composition of water- and suction-extracted DOC: the total % carbohydrate + protein + amino acid C was significantly higher in Oct than Dec, Feb and Jun for water-extracted DOC and significantly greater in Dec than Aug, Apr and Jun for suction-extracted DOC. There was no significant change in the total % carbohydrate + protein + amino acid C of centrifuge-extracted DOC during the sampled year. Time of extraction also had a significant effect on the % protein + amino acid N in water- and centrifuge-extracted DON: Oct levels were significantly higher than Feb for water-extracted DON and significantly higher in Aug and Apr for centrifuge-extracted DON. Concentrations of total DOC and total DON were also found to be dependent on time of extraction. DOC concentrations showed a similar pattern of variation over the year for all methods of extraction, with concentrations relatively constant for most of the year, rising in April to reach a peak in Jun. DON concentrations in water- and centrifuge-extracted DON peaked later, in Aug. There were no significant seasonal changes in the concentration of suction-extracted DON. A lack of correlation between DOC and DON concentrations suggested that DOC and DON production and/or loss are under different controls. Laboratory-based incubation experiments were carried out to examine the dynamics of DOC biodegradation. Over a 70 day incubation period at 20oC, the DOM from two types of peat (raised and blanket) and four samples of a mineral soil (calcaric gleysol), each previously exposed to a different management strategy, were found to be comprised of a rapidly degradable pools (half-life: 3 – 8 days) and a more stable pool (half-life: 0.4 to 6 years). For all soil types/treatments, excepting raised peat, the total net loss of DOC from the culture medium was greater than could be accounted for by the process of mineralization alone. A comparison between net loss of DOC and loss of DOC to CO2 and microbial biomass determined by direct microscopy suggested that at least some of the differences between DOC mineralised and net DOC loss were due to microbial assimilation and release. Changes in the microbial biomass during the decomposition process showed proliferation followed by decline over 15 days. The protein and carbohydrate fractions showed a complex pattern of both degradation and production throughout the incubation. The effects of repeated applications of trace amounts of litter-derived DOC on the rate of carbon mineralization over a 35 day period were investigated in a laboratory based incubation experiment. The addition of trace amounts of litter-derived DOC every 7 and 10.5 days appeared to ‘trigger’ microbial activity causing an increase in CO2 mineralisation such that extra C mineralised exceeded DOC additions by more than 2 fold. Acceleration in the rate of extra C mineralised 7 days after the second addition suggested that either the microbial production of enzymes responsible for biodegradation and/or an increase in microbial biomass, are only initiated once a critical concentration of a specific substrate or substrates has been achieved. The addition of ‘DOC + nutrients’ every 3.5 days had no effect on the total rate of mineralization. To date DOC has tended to be operationally defined according to its chemical and physical properties. An understanding of the composition, production and loss of DOC from a biological perspective is essential if we are to be able to predict the effects of environmental change on the rate of mineralization of soil organic matter. This research has shown that the pools of DOC extracted, using three different methods commonly used in current research, are biochemically distinct and respond differently to the seasons. This suggests some degree of compartmentalisation of biological processes within the soil matrix. The observed similarities between the characteristics of the decomposition dynamics of both peatland and agricultural DOC suggests that either there is little difference in substrate quality between the two systems or that the microbial community have adapted in each case to maximise their utilisation of the available substrate. The dependency of the concentration and biochemical composition of DOC on the seasons requires further work to ascertain which biotic and/or abiotic factors are exerting control. Published research has focussed on factors such as temperature, wet/dry cycles, and freeze/thawing. The effect of the frequency of doses of trace amounts of DOC on increasing the rate of soil organic C mineralization, evident from this research, suggests that the interval between periods of rainfall may be relevant. It also emphasises how it can be useful to use knowledge of a biological process as the starting point in determining which factors may be exerting control on DOC production and loss.

Full textAbstract:
This work deals with the life and, particularly, the political career of Dr. Rollin Bunch, a three-term mayor of Muncie, Indiana. There are several valid reasons why Bunch's life and career deserve a study. Simple chronology is a major reason. Bunch's first two terms were during the tumultuous World War I era, and his final administration occurred during the equally historic Depression of the 1930s.Another reason to pursue this study is that Bunch represents both the political bossism of the turn of the century and the idealism expressed by the New Deal. By employing old-fashioned power politics to obtain progressive and liberal goals, Bunch proved to be an innovative leader. His frequent legal problems, including several indictments and even a federal prison term, also make him an interesting case study.Primary data, which consists of sources not contaminated by the opinions and prejudices of others, will provide most documentation. Contemporary newspapers have been my main source. The newspapers most used in this study are two conservative, Republican daily papers, The Muncie Morning Star and The Muncie Evening Press. Two defunct weekly papers were also studied, The X-Ray and The Muncie Post Democrat. The X-Ray was a barely coherent anti-Semitic paper, whereas The Muncie Post Democrat was published by another Muncie mayor and bitter enemy of Bunch, George Dale. All four newspapers routinely vilified Bunch, which makes his substantial electoral success even more remarkable.Personal interviews were another major source. The main problem was finding people who could clearly recall the events of six to seven decades ago, not an easy task. Despite these inherent problems, documentation concerning Bunch was available from several sources.I believe this dissertation will add substantially to the body of work available concerning local histories generally, and Muncie and Delaware County particularly.Department of History

Previous issue date: 2014-12-15This study isaimed at learning more about the meanings of teaching to Primary Education teachers in public schools, from the perspective of Education for All. This is a qualitative study with a descriptive nature, which uses semistructured interviews as an instrument for collecting information for later analysis of the content. The universality of eduction requires quality practices that simultaneously provide access to schooling for all and any children, while ensuring their permanence. An inclusive proposal follows this line, especially so when considering that it arises as recognition of exclusion and selectivity in traditional schooling. However, much desired education inclusion has been facing serious problems. There is still a huge gap between so-called inclusive educational policies and the reality experienced in educational practices encountered at schools. Previously, inclusion actions were aimed more at explaining and objectifying educational legislation and policies, with few making the effort to understand the subjective meanings that teachers education professionals and responsible for implementing the proposal have been attributing to it. In view of the teachers' "resistance" towards the proposal. The aim is to investigate the meaning of teaching to Primary Education teachers in public schools, in terms of the educational inclusion process. The procedures employed in the study shift from the empirical to interpretative, from speech to meaning, seeking to understand the specific needs of each teacher, expressed by them in some manner. Among the authors that form a base for this paper are students of historical-social theory like Vygotsky and followers, with an emphasis on Fernando Gonz?lez Rey.. The target public includes four Primary Education coordinator teachers, with two having only a few years of experience and the other two with more than fifteen years of experience coordinating primary education classes. The analysis of data shows us that the aforementioned "resistance" towards the inclusive proposal originates from beliefs and values that permeate their life experiences, which makes it necessary to create space for autonomy, discussion, critical reflection, and the creation of projects that arise from joint effort and promote writing. Spaces that foster significant content for teachers in their current contexts of life, so they can identify their desires, aspirations, beliefs and thereby resignify them, generating new meanings and leading them to contribute in a manner they judge more effective for quality education in which all children feel welcome.

O presente trabalho objetiva identificar e analisar os aspectos relativos ao ensino da matem?tica a partir do desenvolvimento de um projeto de letramento com alunos do 9? ano do ensino fundamental. A pesquisa foi realizada em uma escola p?blica do munic?pio de Mamanguape, no estado da Para?ba - Brasil. Para tanto, tomamos os referenciais te?ricos do letramento e projeto de letramento (KLEIMAN, 1995; 2000; 2005; 2007; STREET, 2007; 2014), leituras e escritas nas aulas de Matem?tica (SMOLE & DINIZ, 2001; LIMA E NORONHA, 2014) e g?neros discursivos (LEITE & BARBOSA, 2014). O percurso metodol?gico da pesquisa consistiu na elabora??o e desenvolvimento de um projeto de letramento nas aulas de matem?tica, que teve como foco tem?tico ?O uso da ?gua? e por t?tulo ?Abastecimento e armazenamento de ?gua no munic?pio de Mamanguape-PB?. De natureza qualitativa, a investiga??o ? caracterizada como pesquisa-a??o, pois a atua??o do professor-pesquisador n?o foi limitada ? mera observa??o das a??es, mas um sujeito que reflete, interv?m, analisa e transforma sua pr?tica docente e aprende com os sujeitos envolvidos na pesquisa (GIL, 2010). A an?lise dos dados que foram constru?dos ao longo do desenvolvimento do projeto de letramento, deu-se em uma perspectiva (auto)reflexiva que considerou o processo de (re)elabora??o do planejamento de ensino e da pr?tica docente presentes no processo dial?gico, estabelecido entre os sujeitos de letramento e decorrentes da viv?ncia de momentos de planejamento individual e coletivo, de pr?ticas de letramento e da compreens?o e reformula??o dos conceitos matem?ticos envolvidos. Os resultados apontam para aprendizados docentes emergentes das reflex?es do professor e aprendizados matem?ticos e sociais dos alunos.
This paper aims to identify and analyze the aspects concerning Mathematics teaching from the development of a literacy project with students from 9th grade of elementary school. We performed the survey in a public school in Mamanguape, Paraiba, Brazil. In order to do that, we analyzed the theoretical frameworks of literacy and literacy project (KLEIMAN, 1995; 2000; 2005; 2007; STREET, 2007; 2014); reading and writing activities in Mathematics classes (SMOLE & DINIZ, 2001; LIMA AND NORONHA, 2014) and speech genres (LEITE & BARBOSA, 2014). The methodological research course consisted in the design and development of a literacy project in Math classes, which had as its thematic focus "The use of water" and entitled as "Water supply and storage in Mamanguape-PB". Since it is a qualitative research, we characterize this investigation as an Action-Research, because the role of the teacher-researcher was not limited to mere observation of the actions, but to being subjects who reflect, intervene, analyze and transform their teaching practice and learn from those involved in the research (GIL, 2010). The data analysis that we performed along the literacy project development took place in a self-reflective perspective that considered the process of (re) developing the educational planning and the teaching practice ? both present in the dialogical process. This was established between the subjects of literacy and due to the experience of individual collective moments of planning, of literacy practices and of understanding and reformulating the mathematical concepts involved. The results point to the teacher?s learning, which came from their reflections, and to the students? mathematical and social learning.

Full textAbstract:
Diese Projektarbeit versucht zu erklären,
warum Flugzeuge mit drei oder vier Triebwerken kaum noch verkauft werden.
Dabei wird insbesondere der Vermutung nachgegangen, dass Flugzeuge mit einer größeren Anzahl an Triebwerken höhere Wartungskosten haben könnten.
Zur Beantwortung der Frage werden sechs verschiedene Methoden zur Berechnung von Betriebskosten (Direct Operating Costs, DOC)
von Passagierflugzeugen herangezogen, die u.a. auch die Kosten der Triebwerkswartung abschätzen.
Vier dieser DOC-Methoden sind von Organisationen: Air Transport Association of America (ATA 1967), Deutsche Lufthansa (DLH 1982),
Association of European Airlines (AEA 1989), Airbus Industrie (AI 1989).
Zwei DOC-Methoden wurden an Universitäten entwickelt und sind von Jenkinson bzw. von Thorbeck (TU Berlin, TUB).
Weiterhin werden grundsätzliche flugmechanische Überlegungen angestellt und die Literatur durchgesehen,
die aber nur wenige Hinweise zur Beantwortung der Fragestellung enthält.
Die Gleichungen zur Berechnung der Triebwerkswartungskosten aller sechs Methoden werden dargelegt und erklärt.
Die Methoden unterscheiden sich stark in ihrer Komplexität.
Da die Methoden sich auf unterschiedliche Jahre beziehen werden die Kosten mit einem Inflationsfaktor auf das Jahr 2017 umgerechnet
und somit vergleichbar gemacht. Zum Vergleich werden weiterhin die Gleichungen zur Berechnung der Wartungskosten der Flugzeugzelle angegeben.
Zur Berechnung der Triebwerkswartungskosten wurden vier in der Größe vergleichbare Mittelstreckenflugzeuge ausgewählt:
B737-800, A318 (zwei Triebwerke), Jak-42 (drei Triebwerke), BAE 146-300 (vier Triebwerke).
Weiterhin wurden vier in der Größe vergleichbare Langstreckenflugzeug ausgewählt:
A330-300 (zwei Triebwerke), MD11-ER, TriStar (drei Triebwerke), A340-300 (vier Triebwerke).
Zum Vergleich eignen sich besonders der A330 und der A340 da die Technik, das Alter und die Abmaße sehr eng bei einander liegen.
Im Ergebnis wurde festgestellt, dass sich die Aufteilung der Wartungskosten zwischen Zelle und Triebwerken uneinheitlich zeigt.
Die AI-Methode ergibt im Vergleich viel zu hohe Triebwerkskosten.
Der Grund dafür ist die direkte Multiplikation von Schub mit den Lohnkosten.
Die AI-Methode muss daher bei der Endanalyse unberücksichtigt bleiben.
Bei den Mittelstreckenflugzeugen lieferten die Methoden nach AEA, DLH und TUB ähnliche Ergebnisse.
Bei den Langstreckenflugzeugen lieferten die AEA-Methode, DLH-Methode und die Methode nach Jenkison ähnliche Ergebnisse.
Empfohlen werden kann damit eine Berechnung mit der AEA-Methode, die auch öffentlich ist.
Für einen Endvergleich wurden für die Mittel- bzw. Langstrecke zu jeder Triebwerksanzahl nur jeweils ein Flugzeug einbezogen.
Mit dieser bereinigten Auswahl bei Flugzeugen und Methoden ergab sich für die Mittelstrecke eine leichte Abnahme der Triebwerkswartungskosten
mit der Triebwerksanzahl von nur 6,1 US$ pro Flugstunde pro Triebwerk (Zunahme von -6,1 US$/FH/Triebwerk).
Für die Langstrecke ergab sich eine leichte Zunahme der Triebwerkswartungskosten mit der Triebwerksanzahl von nur 32,5 US$ pro Flugstunde pro Triebwerk.
Damit konnte die eingangs genannte Vermutung über eine Zunahme der Triebwerkswartungskosten mit der Anzahl der Triebwerke nur zum Teil bestätigt werden.
Die Analyse zeigte, dass die Triebwerkswartungskosten von vielen Parametern abhängen, die Triebwerksanzahl ist nur ein Parameter von vielen.
Selbst ähnliche Flugzeuge liefern bei gleicher Triebwerkszahl daher Triebwerkswartungskosten,
die sich stark unterscheiden und die Abhängigkeit von der Triebwerkszahl wenig sichtbar werden lassen.
Es werden Vorschläge gemacht, welche anderen methodischen Ansätze hier Abhilfe schaffen könnten.

Full textAbstract:
Im Fokus der Untersuchungen steht das hydrologische Einzugsgebiet der oberen Wilzsch im Westerzgebirge. Veränderte Stoffausträge des bewaldeten und zum Teil vermoorten hydrologischen Einzugsgebietes führen zu erhöhten Stoffkonzentrationen im Hauptzufluss der Trinkwassertalsperre Weiterswiese (Carlsfeld). Seitens der Trinkwasseraufbereitung stellen insbesondere die gestiegenen Gehalte an gelösten organischen Kohlenstoffen (DOC) Mehraufwendungen dar. Im Zuge der Wiedervernässung der Moorflächen kommt es zu relevanten bodenchemischen Veränderungen, die im Abfluss messbar sind.
Eine räumliche Betrachtung der Teileinzugsgebiete des hydrologischen Einzugsgebietes der oberen Wilzsch ermöglicht, das Abflussgebiet in verschiedene Herkunftsräume zu gliedern. Dieser raumbezogene Ansatz leistet einen wesentlichen Beitrag in der Herkunftsanalytik von Wässern, deren Fließwege durch Standorte unterschiedlicher Nutzung geprägt sind.
Die Arbeit bedient sich hydrochemischen Analysen sowie multitraceranalytischen Verfahren. Die Analyse der stabilen Umweltisotope ²H und 18O am Wasser, 13C am DIC und DOC, 34S und 18O am Sulfat sowie 15N und 18O am Nitrat hilft bei der Identifizierung von Stoffquellen und Transformationsprozessen. Die Arbeit verfolgt das Ziel, den Beitrag der verschiedenen Stoffsysteme am gesamten Stoffaustrag des Vorfluters aufzuzeigen sowie die atmosphärische Grundlast an den Messstandorten nachzuweisen. Dazu wurden von Mai 2009 bis August 2010 fünf Beprobungskampagnen angelegt. Das Messdesign erstreckte sich auf 19 Standorte in ausgewählten Teileinzugsgebieten, die maßgeblichen Einfluss auf die Vorflut haben. Parallel dazu erfolgte die Untersuchung des Niederschlags an der Station Talsperre Weiterswiese. Erfasst wurden die Inhalte von Wässern verschiedener Moorgebiete, Moorwasserpegel unterschiedlich
degradierter Moorbereiche, Gräben und Bodendrainagen im Fichtenforst, der Vorfluter Wilzsch und Kranizsch und des Grundwassers im Fichtenforst.
Es kann festgehalten werden, dass je nach Lage bzw. Entfernung der Ursprungsgebiete der Anteil des DOC - Exports unterschiedlich stark ist. So sind die DOC - Austräge saisonal sehr verschieden. Im Ergebnis ist der hydrochemische Beitrag - im Besonderen DOC - der unterschiedlichen Stoffsysteme des hydrologischen
Einzugsgebietes letztlich am finalen Pegel der Wilzsch messbar. Die vom Basisabfluss gesteuerten silikatischen Standorte im Fichtenforst leisten einen wesentlichen Anteil zum hydrochemischen Milieu der Vorfluter. Die im Untersuchungsgebiet eingeleiteten Renaturierungsmaßnahmen beeinflussen die Trinkwasserqualität
in der Talsperre Carlsfeld nicht. Eine Abgrenzung der atmosphärischen Grundlast ist ebenfalls möglich, atmogen eingetragene Stoffe können an den Standorten ausgewiesen werden.

The present study has teaching and students? different learning processes as its subject matter, and aims to raise the issue of how the learning processes of students in their First Years of Elementary School are comprehended and confronted by teachers in everyday class teaching. Through interviews, we sought to look into which pedagogical alternatives teachers dispose of to face their students? learning difficulties, the implications of different learning processes in students? education and in teachers? practices, as well as experiences lived by teachers while teaching students who present varied learning difficulties. The methodological approach of such research is qualitative, and the procedure for collecting data addresses a semi-structured interview, which had a predefined script. We interviewed six First-Year-Elementary-School teachers from two schools ? a private and a public one, in the city of Novo Hamburgo, RS (South of Brazil). The analysis of the collected data was based on Discursive Textual Review as a technique, which made it possible to infer that teachers comprehend the different learning processes of those students in their First Years of Elementary School according to their own conceptions, which support their teaching, and also that the teachers? confrontation of these students? different learning processes is connected to how teachers themselves feel regarding such processes as well as to their reflexive practices, the pedagogical alternatives that they dispose of, the support network that assists them and, in addition, to the challenges they bump into in their everyday practices. This study also appoints the urge for the establishment of an interdisciplinary dialogue that fields all students? learning processes, which not only shows out the need to think over these subjects? learning, but also articulates the various theoretical approaches, which will support the comprehension of the subjects? full development, as well as to think over teachers? initial education in itself, through the restructure of the Pedagogy courses syllabus. The latter do address the importance of interdisciplinarity; however, they continue to have their syllabus structured so as to be made of piecemeal knowledge. Consequently, teachers will face much difficulty acknowledging the process to the student?s full development, as well as the different learning processes presented by them.
O presente estudo tem como tema a doc?ncia e os diferentes processos de aprendizagem dos alunos e objetiva problematizar como os diferentes processos de aprendizagem dos alunos dos Anos Iniciais do Ensino Fundamental s?o compreendidos e enfrentados pelos docentes no cotidiano da sala de aula. Por meio de entrevistas, procurou-se investigar quais as alternativas pedag?gicas de que o professor disp?e para o enfrentamento das dificuldades de aprendizagem dos seus alunos, as implica??es dos diferentes processos de aprendizagem na escolariza??o dos alunos e na pr?tica do professor e tamb?m as experi?ncias formadoras vivenciadas pelo professor ao longo da sua doc?ncia com alunos que apresentam diferentes dificuldades de aprendizagem. A abordagem metodol?gica da pesquisa ? de cunho qualitativo, e o procedimento de coleta de dados se refere ? entrevista semiestruturada, com roteiro preestabelecido. As entrevistas foram realizadas com seis professoras dos Anos Iniciais do Ensino Fundamental de duas escolas ? uma da rede privada e outra da rede p?blica de ensino ? da cidade de Novo Hamburgo, RS. A an?lise do material coletado teve como t?cnica a An?lise Textual Discursiva, por meio da qual foi poss?vel inferir que os professores compreendem os diferentes processos de aprendizagem dos alunos dos Anos Iniciais do Ensino Fundamental com base nas pr?prias concep??es, que sustentam a sua doc?ncia, e que o enfrentamento desses diferentes processos de aprendizagem dos alunos pelos professores est? relacionado a como estes se sentem em rela??o a esses processos, ? sua pr?tica reflexiva, ?s alternativas pedag?gicas de que disp?em, ? rede de apoio que os auxilia e tamb?m aos desafios que eles encontram na sua pr?tica cotidiana. Este estudo aponta tamb?m a necessidade de que se estabele?a um di?logo interdisciplinar que d? conta dos diferentes processos de aprendizagem dos alunos, que mostre n?o s? a necessidade de se pensar a aprendizagem desses sujeitos, mas que articule as diferentes abordagens te?ricas que dar?o subs?dios para compreender o processo de desenvolvimento integral do sujeito, como tamb?m para pensar sobre a pr?pria forma??o inicial dos professores, por meio da reestrutura??o curricular dos cursos de Pedagogia. Estes falam da import?ncia da interdisciplinaridade, mas continuam a ter seus curr?culos estruturados de modo a constituir um conhecimento fragmentado. Como consequ?ncia, os professores t?m muitas dificuldades para perceber o processo de desenvolvimento integral do aluno, bem como os diferentes processos de aprendizagem que apresentam.

Full textAbstract:
This study argues how Italian wine is accepted by consumers’ in Japan. In specific, this study chooses Soave DOC wine in Veneto Region. The reasons why Soave wine was accepted by the Japanese consumers has two
characteristics: exotic image by Country of Origin effect of Italy and also its familiarity for them.
The structure of this study is the following.
Chapter I explains the Background, Research Question and Paper configuration.
Chapter II reviews the existing literatures in order to form hypotesis of this study. First, it explains the concept of Country of Origin effect: define Product Country Image (PCI) and Territory of Origin (TOO) concept. These concepts underline the country tradition, the feature that are capable of influence consumers choice when they approach to purchase a product with a “made in” label. Image of Italy for consumers’ in Japan have two different aspects: fashionable and also traditional. The study focuses to Made in Italy features and Japanese consumers’ opinion toward it. Secondly, consumers need are argued about wine. Third, after describing the history of wine also in Japanese wine market focusing on Italian wines, the study practices Marketing strategies in Japan. Fourth using the framework of Brannen (1992), the study argues that when foreign products are accepted by the Japanese market, they have binomial characteristics: exotic and familiar. Based on these literatures, the study constructs its hypothesis as follows: Soave wine was accepted by the consumers in Japan because it has two characteristics of exotic and familiar.
Chapter III is devoted to explain the methodology of the research. Three different researches are conducted. A survey has been sent trough internet to consumers in Japan, both female and male between the ages of 20 up to more
than 50 years old. Therefore, the survey has been made to gather answers able to confirm hypothesis and understand what kind of feeling have Japanese consumers toward Italian wines and Soave wine. Moreover, to confirm my hypothesis this study based to interviews with Mr. Shigeru Hayashi, a famous first sommelier in Japan, and Mr. Aldo Lorenzoni, director of Soave wine Consortium.
Chapter IV analyses the data gathered and verifies the hypothesis. The survey and interviews were focused to notorious image of Italy and familiarity approach with it.
Chapter V argues the findings of the research, gives theoretical and practical implications and describes limitations of this study.

Full textAbstract:
Seasonal periods of high rainfall and changes in land management have led to difficulties for UK water companies to remove sufficient natural organic matter (NOM) to stay in compliance with the tightening trihalomethane (THMs) standards. Hence alternative treatment options have come into focus of research and development. The continuous anion exchange process based on a novel magnetic resin (MIEX® resin) has emerged as a promising method to increase NOM removal and has been compared in this thesis to the most widely spread drinking water treatment method of coagulation with hydrolysing metal salts. Therefore the removal efficiency of both processes was investigated by treating different natural waters sources as well as selected organic model compounds of different hydrophobicity and molecular weight (MW). Magnetic resin was thereby seen to be competitive with coagulation for DOC removal in low SUVA sources dominated by mid to low MW material and to outperform coagulation for the treatment of low MW, hydrophilic acids. However magnetic resin had to be used in combination with subsequent coagulation using largely reduced Fe doses to ensure high levels of DOC removal in sources dominated by high MW NOM. This was related to a physical blockage mechanism of the easily accessible external resin bead surface by this high MW material. An effect that could be reduced by applying increased resin doses, which provided a larger external surface area for DOC removal. A combination of magnetic resin treatment with coagulation was nonetheless seen to be able to increase DOC removal as well as to generate enhanced floc properties in terms of strength, settling velocity and size. Beside a reduced THM formation potential, making magnetic resin an effective tool to help meet legislative standards, an increased solid-liquid separation was seen in pilot-scale to result from these effects.

Full textAbstract:
A hydrological and biogeochemical study was undertaken at the Mer Bleue bog, Ottawa, Ontario, Canada from May 22, 1998 to May 21, 1999. Basin runoff was generated by groundwater discharge at the peatland margin, and groundwater discharge was controlled by hydraulic gradients and horizontal hydraulic conductivities (Kh). Flux of dissolved organic carbon (DOC) measured at the basin outflow was 8.3 g C m-2 yr-1 and compared to within 23% of DOC flux estimated using a Dupuit approximation of seepage during the ice-free season. Annual DOC flux was 11% of the annual carbon sink.Flownet analysis showed that seasonal patterns of groundwater flow were controlled by boundary condition changes that resulted from precipitation and evapotranspiration events. A pattern of recharge was most common over the hydrological year, but a discharge pattern was observed during a 40 day groundwater flow reversal. Evaluation of the peatland recharge-discharge function using in situ sodium concentrations and a diffusion model revealed that the peatland is a long-term recharge system. It is hypothesized that peatland biogeochemical function is controlled by long-term recharge despite annual occurrence of groundwater flow reversals.

Previous issue date: 2010-01-08Em todos os discursos, dos te?ricos aos pol?ticos, a educa??o ? apresentada como a melhor alternativa para se atingir o desenvolvimento social e o equil?brio econ?mico que as na??es tanto almejam. No entanto, quase sempre, a figura do professor ? esquecida nestes discursos como se n?o fossem eles os ?nicos capazes de operar a verdadeira mudan?a na educa??o e transformar a sociedade como um todo. Este estudo tem por objetivo investigar os processos de constru??o da identidade docente em professores da educa??o profissional, a partir do problema de pesquisa: como os professores dos cursos t?cnicos percebem a sua identidade profissional. Trata-se de investiga??o de cunho qualitativo na qual o estudo de caso foi escolhido como metodologia de pesquisa. O problema inicial foi posteriormente desdobrado em tr?s quest?es de pesquisa nas quais se questiona a rela??o entre atua??o e identifica??o docente, a rela??o entre forma??o e pr?tica e o sentimento de perten?a ao grupo. O estudo foi realizado com sete professores que atuam em cursos t?cnicos e desempenham outras a??es profissionais paralelas ? doc?ncia. Os dados foram recolhidos em entrevistas semi-estruturadas e analisados por meio da an?lise de conte?do, descrita por Bardin (1977). Da an?lise emergiram as categorias: a??o, reflex?o e rela??o, as quais foram descritas e interpretadas a luz de alguns autores, entre estes: de Kaufmann (2004), N?voa (1992, 1995), Tardif (2006), com os quais aprofundamos e qualificamos as reflex?es acerca de alguns conceitos que permearam o estudo tais como: identidade, professoralidade, forma??o, subjetividade, rela??es e pr?tica docente entre outros. O estudo apontou que os professores da educa??o profissional continuam a ser recrutados no mundo do trabalho e iniciam na doc?ncia sem forma??o pedag?gica e que, embora prevista em lei, a forma??o em servi?o n?o acontece ou n?o contribui para o processo de forma??o da identidade docente desses professores. Mesmo assim, ? poss?vel afirmar que esses professores constroem para si uma identidade profissional/pessoal/docente a partir da ressignifica??o das viv?ncias da escola e do mundo do trabalho.

Previous issue date: 2006-12-13In the teaching history course it s found the female teacher entering, reflecting significantly in the continuous process of her identity redefinitions and reconstruction. This entering brings, even in a silent and not explicit way, the confluence of gender identity to professional identity, in which are present the relations of the proper to female. In the mastership case, these relations are found imbricated in the teaching identity construction and in the translation of this profession as female, based in Virgin Mary, through Mariano ideal diffused by the catholic church. Therefore there is a lanck in educational historiography towards the register of female teachers presence, mainly in male religious institute, the reason of this study, in which we seek to investigate: how to explain that a female identity can give support to a highly male educational project? What relations can we establish between this female identity and the entering of female teachers in Maristas Province Schools of North Brazil? We performed a bibliographic research in Maristas Schools Libraries, of Marista historial, in Recife, of Pontificia Universidade Cat?lica do Paran? (Catholic University), in Curitiba-PR. We searched for support in studies about pedagogy history, of Marista Institute, Catholic Church, Brasilian Education and of Women; Mariologic studies, the referring to Marista Educational Proposal, to feminization and to teaching identity; and feminist theology productions. The empirical research included 10 schools from referred province and Marista Schools from Lisbon Portugal. Through semi-estructured interviews, we interviewed pioneer female teachers, Marista former Brothers and Brothers from those schools, due to their presence and action within the study period and for the concern to save their memories about the theme. The study reveals the particularities of Mariano ideal as female model and teaching, and her presence in Marista Educational Proposal. This study, in a historical approach, aims to contribute to give visibility to the woman in history and teaching construction in Brazil, mainly in religious institutions from male origin

Este ingresso traz, mesmo se de modo silencioso e n?o expl?cito, a conflu?ncia da identidade de g?nero ? identidade profissional, em que est?o presentes as rela??es do adequado ao feminino. No caso do magist?rio, estas se encontram imbricadas na constru??o da identidade docente e na tradu??o desta profiss?o como feminina, embasada na Virgem Maria, mediante o ideal mariano difundido pela Igreja Cat?lica. Por?m h? uma lacuna na historiografia educacional quanto ao registro da presen?a de mulheres professoras, notadamente em institutos religiosos masculinos, elemento motivador deste estudo, no qual buscamos investigar: Como explicar que uma identidade feminina pode dar sustenta??o a um projeto educativo eminentemente masculino? Que rela??es podemos estabelecer entre esta identidade feminina e o ingresso de mulheres professoras nos col?gios da Prov?ncia Marista do Brasil Norte? Realizamos pesquisa bibliogr?fica em bibliotecas dos Col?gios Maristas, do Historial Marista, em Recife, da Pontif?cia Universidade Cat?lica do Paran?, em Curitiba. Buscamos aportes em estudos sobre a Hist?ria da Pedagogia, do Instituto Marista, da Igreja Cat?lica, da Educa??o brasileira e das Mulheres; estudos Mariol?gicos, os referentes ? Proposta Educativa Marista, ? feminiza??o e ? identidade docente; e produ??es da Teologia Feminista. A pesquisa emp?rica abrangeu 10 col?gios da referida Prov?ncia e o Col?gio Marista de Lisboa-Portugal. Por meio de entrevistas semi-estruturadas, entrevistamos professoras pioneiras, ex-Irm?os e Irm?os Maristas desses col?gios, em raz?o da presen?a e atua??o destes no per?odo em estudo e pela preocupa??o em ter salvaguardadas suas mem?rias sobre o tema. O estudo revela as particularidades do ideal mariano como modelo feminino e de doc?ncia e sua presen?a na Proposta Educativa Marista. Este estudo, numa abordagem hist?rica, visa contribuir para dar visibilidade ? mulher na constru??o da Hist?ria e da doc?ncia no Brasil, especialmente em institutos religiosos de origem masculinos

Full textAbstract:
This research examines an approach to modeling and simulating distributed object computing (DOC) systems as a set of discrete software components mapped onto a set of networked processing nodes. Our overall modeling approach has clearly separated hardware and software components enabling systems level, distributed co-design engineering. The distributed co-design engineering refers to a formal approach to concurrent hardware and software systems engineering that provides a tractable method for analyzing the inherent complexities that arise in distributed systems. The software abstraction forms a distributed cooperative object (DCO) model to represent interacting software objects. The hardware abstraction forms a loosely coupled network (LCN) model of processing nodes, network gates, and interconnecting communication links. The distribution of DCO software across LCN processors forms an object system mapping (OSM). The OSM provides a sufficient specification to allow simulation investigations. During simulation, the behavioral dynamics of the interacting DCO software components "load" the LCN processing and networking components in terms of memory utilization, computational demands, and communications traffic. The resource constraints of the LCN components, likewise, impose performance constraints on the associated software objects. Class models of the DCO, LCN, and OSM component structures and behavior dynamics were formally developed using the Discrete Event System Specification (DEVS) formalism. These class model specifications were implemented in DEVSJAVA, a Java implementation of DEVS. Class models of experimental frame components were also developed and implemented to facilitate analysis of individual DCO and LCN components, as well as interdependent system behaviors, during simulations. The resulting DEVS-DOC environment enables distributed systems architects, integration engineers, and automated system designers to conduct performance engineering and trade-off analysis of distributed system structures, topologies, and technologies. This research utilized the resulting DEVS-DOC environment in four case studies. These case studies demonstrate the structural independence and behavioral interdependence of the hardware and software abstractions, the ability to model and simulate real world systems, and the complex interactions that arise in distributed systems can be methodically analyzed.

Full textAbstract:
Sales of Prosecco DOC di Conegliano Valdobbiadene have increased in the Italian domestic market from 2002 to 2006. As far as the HoReCa, an analysis collection of a sample of 169 restaurants, bars and agritourisms of the area shows that there is a strong tie between these and the territory. They have a wide range of labels of Prosecco and supplying happen mainly directly from the wineries of the area. Since Prosecco DOC is enjoying a great success, some problems must be faced because of competition of Prosecco IGT. In fact, these type of Prosecco shows a large increase in the sales in the domestic market. In addition there is the competition of the other wines that can be produced abroad, and commercialized with Prosecco label. A questionnaire designed to assess characteristics of the Prosecco DOC di Conegliano Valdobbiadene district was used to analyse a sample of wineries. The study showed a commercial collaboration between wineries, but, at the same time, a lack of communication with the institutions of the district, yielding negative repercussions on the marketing plans of the product and the territory. This survey has also studied the multifunctionality of a sample of wine grape farms in the Prosecco D.O.C. di Conegliano Valdobbiadene District. The analysis shows some important aspects of the multifunctionality, and the existence of pluri - active families at the head of the same farms. However, the owners do not have the necessary knowledge in order to preserve the landscape and to increase the number of sport and cultural activities offered to the enotourists. A better collaboration between companies and institutions of the district is necessary in order to make marketing plans and win the challenge with the Italian and foreign competitors.

Full textAbstract:
The partitioning of methyl mercury (MeHg) to dissolved organic carbon (DOC) and the photodegradation of mercury by UVB radiation (280-320nm) are two important processes that influence the availability of MeHg to the base of the aquatic food chain.
Water samples from 20 sites across Eastern Ontario and Western Quebec were filtered sequentially using tangential flow ultrafiltration to determine the size distribution of MeHg and DOC and to test whether the concentrations and distribution of these two variables varied in wetlands, lakes and rivers. These filtrates were also analyzed for DOC fluorescence and absorbance. The highest proportions of mean MeHg (47.3 +/- 25.4%), DOC (56.8 +/- 14.5%) and DOC FL (74.5 +/- 11.4%) were found in the low molecular weight fractions (<5 kDa). Significant differences in the distribution and concentration of MeHg amongst filtered samples were found between wetlands, lakes and rivers. MeHg was related to DOC at all size fractions. The low molecular weight organic compounds may be an important contributor to MeHg biomagnification through uptake by bacteria and/or algae.
St. Lawrence river water was collected to test factors that affect the rate of photodegradation of MeHg. Samples exposed to UVB irradiance from a fluorescent lamp and spiked with MeHg(5 ng/L) illustrated significant decreases in concentration with a 31% average loss after 6 hours. No significant difference in photodegradation was found between samples with and without added Fe(II). MeHg concentrations decreased 35.4% and 41.7% after 6 hours of exposure at pH 3 and 5, respectively. It appears that photo-demethylation is a function of UVB exposure, is more rapid in acidic conditions and likely occurs slower under most natural freshwater conditions due to the attenuation of UVB.

Full textAbstract:
Tradicionalmente os métodos utilizados para projetos de aeronaves estão focados na redução de fatores como consumo de combustível ou peso. Entretanto, há necessidade de se implantar modelos mais sofisticados e realistas que considerem adequadamente o ponto vista do operador. O projeto de aeronaves consiste em uma tarefa complexa que integra diversas disciplinas. Contudo, somente nos últimos anos, com o avanço da computação e de novos métodos de otimização, a indústria aeroespacial pôde usufruir de plataformas de projeto e otimização multidisciplinar (MDO). Nesse contexto, este trabalho tem por objetivo desenvolver uma plataforma de otimização multidisciplinar capaz de auxiliar no projeto conceitual de uma aeronave com o menor custo operacional direto (DOC). Foram consideradas disciplinas de peso, aerodinâmica, desempenho e custos. Foram aplicadas equações semi-empíricas, baseadas nas metodologias de Roskam, Torenbeek e Raymer, a fim de se reduzir a carga computacional. Um algoritmo genético foi implantado como método de otimização. No final do trabalho é proposto um estudo de caso que consiste na otimização de uma aeronave de 138 passageiros para uma determinada malha aérea. Os resultados mostraram que o DOC é bastante suscetível a variáveis, tal como preço do combustível. A otimização de apenas um dos componentes do DOC, como o peso ou consumo, não significam a real redução dos custos.

Full textAbstract:
Poésie concrète, visuelle, élémentaire, spatiale, totale etc. , quelle place accorder aux travaux que ces étiquettes tentent de designer? - à partir du dépouillement du corpus constitué par Doc(k)s, revue qui s'est internationalement vouée depuis plus de 20 ans à la publication de tels travaux, il semble que l'on puisse, de Mallarmé jusqu'aux performers, postuler le caractère diachroniquement continu de ces courants, l'existence d'un site commun au sein duquel ils trouvent différentiellement leur place, leur liaison enfin à une transformation sociologique si profonde qu'il parait exclu de considérer comme un épiphénomène sporadique ce qui s'affirme internationalement comme une donnée générale, probablement corrélée à la révolution de la sphère des communications et de ses technologies. A partir de cet horizon une analyse formelle peut être entreprise, visant à caractériser sémiologiquement ces travaux et à tenter une approche taxinomique à partir d'exemples variés de poèmes. En ressort que l'unité profonde de ces travaux vient de ce que tous procèdent au dérèglement des conditions de "l'écriture" et du "texte" littéraire classiques desquels la poésie expérimentale offrirait en quelque sorte le "négatif": d'où le terme générique ici proposé de poésie, la négation que la "barre" tente d'exprimer pouvant être perçue comme indiquant aussi bien la "distance critique" vis à vis du "texte" que le refus des frontières entre les secteurs de l'art. Pour envisager ces poètes un décloisonnement disciplinaire et une approche sémiologique s'imposent à quoi Doc (k) s'offre comme un domaine de recherche particulièrement adapte. L'objet premier de cette recherche serait l'écrit non séparé de ses conditions de réalisation et diffusion, de ses techniques d'impression et plus généralement de son contexte d'émission / réceptionConcrete, visual, elementary, spatial, total or behavioral poetry-what place should be given to the works these approximate labels attempt to describe? Systematic study of the corpus of Doc(k)s, a magazine which in a period of more than 20 years has published an international selection of such research, suggests that, from Mallarme to present-day performers, it is possible to postulate the diachronically continuous nature of these currents, the existence of a common site within which they find their place differentially, and their ties to sociological change so deep-reaching that it must be considered as a general and international given, a constant probably linked to the revolution in communications technologies. Starting from this viewpoint some formal analysis can be undertaken in order to characterize these works, to attempt a taxonomic approach, to propose the commentary of examples from varied types of poems. Overall, the idea is that the basic unity of these works stems from the fact that they lead to the systematic dismantling of the conditions of classical writing, of which experimental poetry would offer a sort of "negative". To designate these currents the generic term of poetry is suggested; the negation expressed by the line through the word can be perceived as indicating both the critical distance from the "text" and the act of moving beyond the traditional borders between the various sectors of the art. To consider these poets requires breaking down the walls between disciplines and taking a semiological approach and Doc(k) s appears to offer a particularly well-adapted field of research for formulating such a semiology. The primary object of the research would be the writing not separated from the conditions in which it is carried out and published, from the techniques used to print it and more generally the context in which it is broadcast and received

Full textAbstract:
Allochthonous organic carbon is increasing and leading to browning of freshwaters in the northern hemisphere. It is already known that an increase in allochthonous dissolved organic carbon (DOC) affects benthic primary production and respiration negatively via light limitation, however, little is known about the impact on benthic bacteria. This report aims at examining how DOC and other environmental variables affect the production and growth of benthic bacteria. This was done by analyzing data from 18 lakes in northern Sweden with different DOC concentrations. This analysis was divided into two datasets: one including data at the whole lake scale and the other including data over depth within the lakes. The result showed that DOC, average depth, and the light extinction coefficient all had a negative impact on bacterial production on a whole lake scale. The light extinction coefficient was also affecting the whole lake bacterial growth efficiency (BGE) negatively. Over depth within the lakes a higher light input increased the bacterial production. In the same dataset, light was also affecting the BGE positively, while temperature had a negative effect. The results can thus be linked to the increase in allochthonous carbon and brownification. Because allochthonous DOC have a negative effect on benthic primary production, there will be less autochthonous DOC available for benthic bacteria. Allochthonous DOC is considered less degradable than autochthonous DOC. The increase in allochthonous DOC therefore has a negative impact on benthic bacterial production, likely connected to a decrease in production of autochthonous DOC by benthic algae.

During the year 1998-1999 samples of seawater were collected fortnightly except during the spring bloom in 1999 when samples were collected on a daily basis from the Menai Strait North Wales, U. K. Seasonal cycles of dissolved organic carbon (DOC), nitrogen (DON), yellow substance (YS), particulate organic carbon (POC), nitrogen (PON), and primary productivity were followed. Furthermore Chlorophyll a concentrations and counts of bacterial abundance and phytoplankton species were made along with measurement of physical and chemical parameters. The phytoplankton species succession followed more or less similar pattern to previous studies in the region but with minor differences such as the occurrence of Leptocylindrus sp. blooms during summer in both years. Significant correlations were found between DOC and POC as well as DON and PON. YS was significantly correlated with DOC but not with salinity showing less evidence of riverine and runoff contribution. There was proportionality between the intensities of chlorophyll a and the subsequent DOC peaks and the time lag between primary production and increase in bacterial abundance, showing that a major part of the DOM in the Menai Strait is produced through degradation of particulate organic matter.

Os estudos em forma??o docente t?m encontrado na teoria das representa??es sociais um olhar que permite amplas reflex?es acerca das diversas dimens?es que norteiam a Educa??o em suas especificidades. Nesse sentido, esta pesquisa buscou verificar a representa??o social dos licenciandos participantes do Programa Institucional de Bolsa de Inicia??o a Doc?ncia - PIBID/UFRN acerca da doc?ncia. Para tanto, pautamos nosso olhar sob dois pilares: o primeiro, ? luz das Diretrizes Curriculares Nacionais para a forma??o inicial em n?vel superior e para a forma??o continuada de 2015, que considera a doc?ncia como a??o educativa; e, o segundo, sob o prisma da doc?ncia como a??o social. Nesse sentido, apontamos as representa??es sociais dos licenciandos participantes do PIBID, destacando os elementos centrais, intermedi?rios e perif?ricos; e verificamos a interfer?ncia do programa na forma??o desses estudantes, refletindo sobre os impactos dessa forma??o para a profiss?o docente. Para realizarmos a pesquisa apresentada, utilizamos por lastro tr?s pressupostos te?ricos: forma??o docente, pol?ticas p?blicas para a educa??o e representa??es sociais. Tais pressupostos est?o ancorados nos estudos de N?voa (1995, 1999, 2009), Perrenoud (1997, 2000, 2002), Freire (1996), Ramalho; Nu?ez e Gauthier (2004), Tardif (2005), Tardif e Lessard (2013); Moscovici (1978), Jodelet (2001), Jovchelovitch (1994), S?

Para an?lise documental nos fundamentamos na legisla??o contemplada pela LDB/1996, PNE (2014/2024), Decreto e Portaria de regula??o do PIBID e o Projeto institucional - PIBID/UFRN. Na dimens?o emp?rica, utilizamos, para a coleta de dados, a T?cnica de Associa??o Livre de Palavras - TALP, o question?rio socioecon?mico e a entrevista semiestruturada. No tocante a an?lise e interpreta??o dos dados, adotamos para tratamento quantitativo os softwares EVOC e Excel e para tratamento qualitativo, a An?lise de Conte?do (BARDIN, 2010). Os resultados evidenciaram os sentidos atribu?dos ? doc?ncia, entendida, pelos sujeitos da pesquisa, como um elemento complexo perpassado por cinco campos sem?nticos: a doc?ncia como voca??o, como forma??o, como profiss?o, como meta e como saber/fazer. Esses campos sem?nticos indicam um sentido multifacetado da doc?ncia e evidenciam uma representa??o social em processo cont?nuo de constru??o, guiados pelas transforma??es sociais que est?o em constante movimento.

Pour ce faire, nous orientons notre regard sur deux piliers: Le premier, ? la lumi?re des Diretrizes Curriculares Nacionais pour la formation iniciale en niveux superieur e pour la formation continu?e de 2015, qui consid?re l?enseignement comme action educatif; et, le deuxi?me, sur le prisme de l?enseignement comme action sociale. En ce sens, nous avons montr? les representations sociales des ?tudiants participants du PIBID, en soulignant les ?lements centraux, interm?diaires et p?riph?riques; et nous avons constat? l?interf?rence du programme en la formation de ces ?tudiants, refl?tant sur les impacts de cette formation pour la profession d?enseignant. Pour r?alizer la pr?sente recherche, nous avons employ?, comme fondement, trois principes th?oriques: formation de l?enseignant, politiques publics pour l??ducation et repr?sentations sociales. Telles fondements sont ancr?s aux ?tudes de N?voa (1995, 1999, 2009), Perrenoud (1997, 2000, 2002), Freire (1996), Ramalho; Nu?ez e Gauthier (2004), Tardif (2005), Tardif e Lessard (2013); Moscovici (1978), Jodelet (2001), Jovchelovitch (1994), S? (1998), Minayo (1994), Abric (1998), entre autres, qui nous ont permit une r?flexion pertinente. Pour l?analyse documentaire nous avons bas? dans la l?gislation envisag?e pour la LDB/1996, PNE (2014/2024), le d?cret et l?ordonnance de r?glementation du PIBID et le project institutionnel - PIBID/UFRN. Dans la dimention empirique, nous avons utiliser, pour la collecte des donn?es, la T?cnica de Associa??o Livre de Palavras ? TALP, le questionnaire socio-?conomique et l?interview demi-structur?e. Dans le propos de l?analyse et interpr?tation de donn?es, nous avons adopt?, pour traitement quantitatif, les logici?les EVOC et Excel; et, pour le traitement qualitatif, l?An?lise de Conte?do (BARDIN, 2010). Les r?sultats ont mis en ?vidence les sens attribu?s a l?enseignement, entendu pour les sujets de la recherche, comme un ?l?ment complexe pass? par cinque champs s?mantiques: l?enseignement comme vocation, comme formation, comme profession, comme but, et savoire/faire. Ces champs s?mantiques indiquent un sens ? multiples facettes de l?enseignement et mis en ?vidence une repr?sentation sociale en continue constuction, conduits pour les transformations sociales qui sont en constant mouvement.

Full textAbstract:
The climate change is expected to affect especially alpine areas negatively, replacing the alpine flora with subalpine forest. The understanding of how vegetation influences total organic carbon (TOC) in soil, streams and lakes in alpine and subalpine areas will lead to a better understanding of the effects of climate change, and will also increase the knowledge of the ecotone as a whole. In this study plant-soil relations were examined in a subalpine and an alpine catchment in the north of Sweden, by comparing dissolved organic carbon (DOC) concentrations, 13C-DOC, 13 compared with lake and stream water DOC, as well as sediment OC from the recipient lakes in the catchments.
The results show that subalpine forests at lower altitudes, have higher DOC concentrations, higher C:N ratios, and more depleted Particulate OM in water and inlets, show that allochthonous carbon influences water properties in both catchments, as does primary production by benthic and pelagic algae, separating shallow and deep sediment Differences between the catchments are explained with the higher primary production of organic material and root exudations from trees in the subalpine forested catchment effecting the whole catchment dynamics.

Concentrations of dissolved organic carbon (DOC) measured within water bodies have been increasing on a global scale over the last two decades. Changes in temperature and rainfall have been shown to increase the production and export of DOC from catchments with peat soils in the UK (Freeman et al., 2001). However it is not clear whether increases in DOC concentrations are caused by production increases induced by temperature changes or by a greater incidence of high flows induced by rainfall changes. Increases in both temperature and rainfall have been predicted in Scotland over the next few decades (Kerr et al., 1999) which may further increase current DOC concentrations and exports. The implications of this include both a decrease in water quality and an increase in mobility of metals in upland water bodies. The overall aim of the thesis is to determine if the relationship between dissolved organic carbon (DOC) concentrations and discharge has changed over a 20 year period in small stream catchments in Scotland, in order to better understand the role of hydrology, in driving changes in DOC concentration. To achieve this streams draining two coniferous forest sites and one moorland site were monitored intensively between June 2004 and February 2006. Analysis of the relationship between DOC and discharge, within the catchments, identified the importance of the amount of precipitation falling on the catchment, antecedent precipitation and season, on the concentration of DOC that was measured within the stream. Models were then developed using variables to represent these drivers in terms of both the production (seasonal sine values and 14 day average temperatures) and movement (log of discharge (log Q), days since previous storm event and rising or falling stage) of DOC. In the Ochil Hills catchment, the best predictive model, used 4 hour average discharge and 1 day average 30cm soil temperatures (R2= 0.88). In the Duchray and Elrig catchments, the best predictive models produced used discharge and seasonal sine values; the strength of the model was greater in the Elrig (R2= 0.80) than the Duchray (R2= 0.48) catchment. The strength of the regression models produced highlighted the importance of precipitation in the movement of DOC to the stream and temperature variables representing production in the surrounding catchment. To determine if dissolved organic carbon (DOC) concentrations had changed within the three study catchments, since previous research was conducted at the same sites in the early 1980s and 1990s (Grieve, 1984a; Grieve, 1994), then regression analysis conducted in the previous research was repeated, so changes in the DOC and discharge relationship could be identified. Analysis of the Ochil Hills regression equations identified higher log of discharge and lower temperature and seasonal sine values in the present study (2004-06), when compared to the previous study (1982-83). This suggests that more DOC is now available for movement from the soil, and that the difference between winter and summer DOC production has decreased, potentially because of increasing temperatures. This would explain the limited increase in DOC concentration within the Ochil Hills stream. In the Duchray and Elrig streams, a large increase in DOC was identified at all discharges when all the models produced were compared between the two sampling periods (1989-90 and 2004-06). The increasing trend in DOC concentrations is too large to have been produced by change in temperature alone and it is suggested that the measured reduction in acidic deposition has resulted in the increased DOC concentrations measured in the Duchray and Elrig. The results from this research have identified that concentrations of DOC have increased in Scottish streams over the last 20 years and that the increases in DOC have been induced, potentially by temperature changes in climate. However, changes in temperature are not the only driver of this change as the reduction in acidic deposition is potentially more important, specifically in areas with base poor geology such as the Duchray and Elrig catchments.

The aim of this PhD thesis is to develop a one-dimensional (1D) mathematical model to study in designing and improving emission control systems such as those in Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF). This was achieved by capturing the fundamental reaction kinetics from the microreactor data within the careful choice of concentrations/ temperatures domain; together with good understanding of the physical phenomena’s occurring in these systems. When considering a DOC, it is important to have a good description of the catalyst activity as a function of Platinum Group Metal (PGM) loading, which in this case is Pt, this enables mathematical models to be used in the optimization of the PGM loading. The work presented here looks at the design of a DOC based aftertreatment system through development of kinetics from data obtained from the microreactor for a wide range of PGM loadings (2.5-75g ft-3). The variation in catalyst activity with different PGM loadings for the key reactions was determined. The model developed in this study predicts well all the experimental data for the various loadings. DPF is another important aftertreatment technology that is used for the control of Particulate Matter (PM) emission from diesel engines. Under favourable conditions, the soot collected on the filter can be removed by oxidation with NO2 from temperatures as low as 200°C. The work presented in this thesis shows the fundamental modelling approach to develop kinetics for soot oxidation by NO2. The selectivity to CO was found to differ only marginally with temperature, and is independent of NO2 concentrations. By modelling these data using a 1D model, the rate equations for the soot-NO2 reaction were determined, and experimental data were predicted.

Abstract
The programme of the DoC-WILs is an init iat ive of the Department of
Communicat ions in collaborat ion with Telkom, established through the Human
Resources Fund to enable human resources development at historically
disadvantaged learning institut ions. The Telecommunicat ions Act No 103 of
1996 establishes a Human Resources Fund to promote the provision of
adequately skilled human resources at all levels of the telecommunicat ions
sector in numbers suf f icient for the telecommunicat ions needs of the count ry.
The DoC-WILs emphasise skills development through the use of ICTs in areas
such as network management , creat ing Web sites, use of E-mail and the World
Wide Web, mult imedia applicat ions and Int ranet development . It is however not
known under what contextual circumstances this kind of ICT-usage will lead to
interact ive learning benef its and how the DoC-WILs should go about achieving
them. This art icle therefore at tempts to shed some light on the condit ions under
which ICT usage could impact on educat ional outcomes desired by the DoCWILs
and on how these DoC-WILs could best go about taking appropriate
act ions to improve the possibility of achieving desired interact ive learning
benef its. It is argue that the ability of the DoC-WILs to successfully achieve
desired benef its is crucially dependent on contextual conditions, policies or
processes that apply to the DoC-WILs or their users. This is in line with the social
shaping of technology approach that local circumstances surrounding the
deployment of ICTs in different sectors of society are more important in shaping the
consequence of ICTs than technological variable.

Previous issue date: 2008-01-15O presente estudo procura investigar a possibilidade de desenvolvimento de tecnologias de si atrav?s da atividade art?stica, na perspectiva de uma est?tica da exist?ncia, visando o bem-estar na doc?ncia. Procurou-se verificar como a atividade art?stica elaborada por docentes se direciona na dimens?o do cuidado de si, mediante a constitui??o de um estilo de vida capaz de promover o desenvolvimento e manuten??o do bem-estar pessoal. Inicialmente fizemos um breve estudo sobre o mal-estar na civiliza??o e as rela??es poss?veis com o mal-estar docente, a fim de abordarmos o bem-estar na doc?ncia, usando como recurso a atividade art?stica. Usamos nesse estudo a metodologia qualitativa, mediante estudo bibliogr?fico e narrativas de vida, tendo como refer?ncia o m?todo de An?lise de Conte?do, descrito por Bardin. Foram realizadas entrevistas semi-estruturadas com 5 professoras da rede estadual de ensino do Rio Grande do Sul, pertencentes a diversas ?reas de conhecimento e diferentes institui??es de ensino. A atividade art?stica ? tomada aqui dentro do principio de que ela ? capaz de promover o encontro consigo mesmo atrav?s da abertura de horizontes, como afirma Gadamer.
