Nabhany, Ahmed Sheikh. « Mapisi ya Kiswahili ». Universitätsbibliothek Leipzig, 2012. http://nbn-resolving.de/urn:nbn:de:bsz:15-qucosa-98033.
Texte intégralRésumé :
Kiswahili, one among the Bantu languages, was formerly called Kingozi, the Waswahili (as they were called by the visiting Arabs) were originally known as Wangozi. Although Western researchers have manifested great interest in Swahili language and culture, they refuse to consider the arguments of their Swahili counterparts, they do accept but their own evidence and analysis. As far as the development of vocabulary and terminologies are concerned, this should be the work of Waswahili per se, scholars and lovers of the language. The author argues that the coining of word had always been in connection with (1) the function, (2) the sound, and (3) the structure of the item to be named. He shows that the lexical and structural richness of Kiswahili in fact can lead to meaningful and reasonable coining of any words necessary. He proposes to continue the work started after the 1975-meeting in Dar-es-Salaam, i. e. to compile vocabularies of the different dialects of Kiswahili which could form a pool from which material can be drawn for coining new words. There is need for all experts to organize their forces. Tanzanian experts should stop doing the whole work alone. They should incorporate their Kenyan counterparts as well. But this is not enough. There is a call for a joint Panel or Committee which shall coordinate all efforts of developing Kiswahili.

O objetivo do trabalho foi avaliar o processo de desidratação osmótica a vácuo do filé de mapará (Hypophthamus edentatus). Filés de mapará com dimensões de 5 x 2 x 0,5 cm foram submetidos a desidratação osmótica a vácuo, de acordo com um delineamento composto central rotacional 24, no qual foram avaliados os efeitos das variáveis independentes temperatura, tempo, pressão de vácuo e concentração de NaCl, sobre as variáveis dependentes perda de água (PA), ganho de sólidos (GS) e atividade de água (aw), visando obter uma condição ótima de processo com maior PA, menor GS e menor aw. A cinética da desidratação osmótica do mapará foi realizada nas condições ótimas, onde foram acompanhados os parâmetros PA, GS e aw, em função do tempo de processo. O modelo empírico proposto por Azuara et al. foi utilizado para representar a cinética de transferência de massa durante o processo de desidratação osmótica. O filé de mapará apresentou 76,70% de umidade, 15,57% de proteínas, 5,38% de lipídeos e 0,93% de cinzas. A concentração de NaCl (linear) foi a variável que apresentou maior efeito sobre as variáveis dependentes, sendo positivo sobre a PA e o GS e negativo sobre a aw. Os modelos obtidos para PA, GS e aw foram significativos a 95% de confiança e apresentaram falta de ajuste não significativa, sendo úteis para fins preditivos. Foi determinada como condição ótima para o processo: concentração de NaCl de 25%, temperatura de 25°C e tempo de 120 min. O modelo proposto por Azuara et al. apresentou bons ajustes aos dados experimentais de PA e GS da cinética de desidratação osmótica do filé de mapará. O filé de mapará sofreu redução de umidade após desidratação osmótica nas condições ótimas, entretanto não atendeu a umidade recomenda pela legislação para pescado salgado, já o teor de cloretos aumentou e atendeu a legislação para pescado salgado. Em relação a cor instrumental, foram observadas, após desidratação osmótica, diferenças estatisticamente significativas para luminosidade (L*) que diminuiu, indicando que o mapará escureceu e para o ângulo de tonalidade (h°) que aumentou, mas ainda indicou tendência ao amarelo.
The aim of this work was to evaluate the process of vacuum osmotic dehydration of mapará fillet (Hypophthamus edentatus). Mapará fillets with dimensions of 5 x 2 x 0.5 cm were subjected to vacuum osmotic dehydration in accordance with a rotational central composite design 24, in which were evaluated the effects of the independent variables temperature, time, vacuum pressure and NaCl concentration on the dependent variables water loss (WL), solids gain (GS) and water activity (aw), order to obtain optimal condition of process with greater PA, lower GS and lower aw. The kinetics of osmotic dehydration of mapará was performed under optimal conditions, where were monitored the parameters PA, GS and aw as a function of process time. The empirical model proposed by Azuara et al. was used to represent the kinetics of mass transfer during the process of osmotic dehydration. The mapará fillet presented 76.70% moisture, 15.57% protein, 5.38% fat and 0.93% ash. The NaCl concentration (linear) was the variable that presented the greatest effect on the dependent variables, being positive on WL and GS and negative about the aw. The models obtained for PA, GS and aw were significant at 95% confidence and showed no significant lack of fit, being useful to predictive purposes. Was determined as optimum condition for the process: NaCl concentration 25%, temperature of 25 ° C and time of 120 min. The model proposed by Azuara et al. showed fit good to the experimental data of PA and GS kinetics of osmotic dehydration of mapará fillet. The fillet mapará had a reduction moisture after osmotic dehydration in optimal conditions, however did not meet the humidity recommended by law for salted fish, since the chloride content increased and attended law for salted fish. In relation the instrumental color were observed, after osmotic dehydration, significant statistically differences in lightness (L *) that decreased, indicating that the mapará darkened and the hue angle (h °) that increased, but still showed a tendency to yellow.

Previous issue date: 2008-11-28Intertidal foraminifera are widely recognized as efficient tools for reconstructing Holocene sea-level changes. They are also used to detect water circulation patterns and to diagnose the physical and chemical characteristics of estuarine water, revealing the steady state of the ecosystem. In this work, surface sediment samples were collected to study recent foraminiferal assemblages in an estuarine portion of the Mapari river basin, Humberto de Campos (MA), Brazil, in two ways: (1) sixteen samples collected landwards along a mangrove transect in the Gato Island, near the mouth of the Mapari river, in the Tubarão Bay, from the tidal muddy flat to the hyperhaline bare flat ( apicum ); (2) nineteen samples collected upstreamwards along the Mapari river, from the Gato Island to the Rampa settlement, where salinity is zero. In the Gato Island transect, salinity and pH were measured and the subaerial exposure time (TES) was calculated for each point. Height and DBH were also measured for the main arboreous individuals. The salinity varied from euhaline to hyperhaline (maximum of 56 ), and demonstrated no relation to TES. It was observed the dominance of Rotaliina suborder almost all along the transect, which means that a vertical zonation of foraminiferal assemblages was not found. However, eight of the sixteen points were collected surrounding a meanderin tidal creek that follows the transect. Considering just these eight points, there is a zonation in two compartments: a lower compartment that groups six samples (TES varying from 36,46% to 58,51%), dominated by Elphidium gunteri, and an upper compartment that groups two samples (TES varying from 61,95% to 75,27%), dominated by Arenoparrela mexicana. In the Mapari river, salinity and pH were measured in surface and bottom water column, and the floristic composition of the channel margins was verified, with special attention to the species of Rhizophora genus. These species have a distribution related to the salinity gradient, that varied from freshwater to euhaline. Four ecofacies were defined: (1) ecofacies 1, that groups the six closest samples to the Tubarão Bay, with polyhaline-euhaline salinity, high diversity index (H ranging from 1,44 to 2,23 and D ranging from 0,48 a 0,69), with dominance of Elphidium gunteri and Nonion sp., significant presence of Ammonia tepida, Quinqueloculina seminulum and Arenoparrela mexicana, and almost exclusive dominance of Rhizophora mangle; (2) ecofacies 2, that groups the next five samples upstreamwards, with mesohaline-polyhaline salinity, dominance of Nonion sp. and E. gunteri, and coexistence of R. mangle, R. harrisonii and R. racemosa; (3) ecofacies 3, that groups five samples with salinity varying from freshwater to mesohaline, wide dominance of Miliammina fusca, with mangrove fringe dominated by R. harrisonii and R. racemosa; (4) ecofacies 4, that groups the three upstream samples, in freshwater environment, where foraminifera are virtually absent. The results corroborate that foraminiferal assemblages can be used as an efficient tool for recognizing the steady state of the complex estuarine environment, where abiotic parameters are highly variable.
Foraminíferos da zona entre-marés são amplamente reconhecidos como eficientes ferramentas para a reconstrução de variações do nível relativo do mar no Holoceno. São também usados para detectar padrões de circulação e diagnosticar as características físicas e químicas das massas d água em ambiente estuarino, revelando as condições dominantes desse ecossistema. Neste trabalho, foram coletadas amostras de sedimento superficial para estudo das associações de foraminíferos recentes, em uma porção estuarina da bacia do rio Mapari, município de Humberto de Campos (MA), Brasil, de duas formas: (1) dezesseis amostras coletadas ao longo de um perfil transversal a um manguezal na Ilha do Gato, próximo ao encontro do rio Mapari com a Baía de Tubarão, partindo da planície lamosa ao apicum; (2) dezenove amostras ao longo do rio Mapari, partindo da Ilha do Gato, com salinidade euhalina, até o povoado Rampa, onde a salinidade é zero. No perfil Ilha do Gato, foram feitas medições de salinidade e pH, e foi calculado o tempo de exposição subaérea (TES) em cada ponto, além de medições de altura e DAP dos principais indivíduos arbóreos. A salinidade varia variou de euhalina a hiperhalina (máximo de 56 ), e não demonstrou nenhuma relação com o TES. Foi observado o domínio da subordem Rotaliina em quase todo o perfil, de forma que não foi encontrada zonação altimétrica das associações de foraminíferos. Oito dos dezesseis pontos, entretanto, foram coletados na borda de um pequeno canal de maré que acompanha o perfil, sendo que, considerando apenas eles, há uma zonação em dois compartimentos, sendo o inferior, com 6 amostras (TES variando de 36,46% a 58,51%), dominado por Elphidium gunteri, e o superior, com 2 amostras (TES variando de 61,95% a 75,27%), dominado por Arenoparrela mexicana. No rio Mapari, foram feitas medições de salinidade e pH (superficial e de fundo para ambos), e foi verificada a composição florística das margens do canal, com especial atenção para as espécies do gênero Rhizophora. Estas espécies se distribuem segundo o gradiente de salinidade, que variou do euhalino à água doce. Quatro ecofácies foram definidas: (1) ecofácies 1, agrupando as 6 amostras mais próximas da Baía de Tubarão, com salinidade polihalina-euhalina, altos índices de diversidade (H variando de 1,44 a 2,23 e D variando de 0,48 a 0,69), domínio de Elphidium gunteri e Nonion sp., presença significativa de Ammonia tepida, Quinqueloculina seminulum e Arenoparrela mexicana, e domínio quase exclusivo de Rhizophora mangle; (2) ecofácies 2, agrupando as cinco amostras da seqüência, com salinidade mesohalina-polihalina, domínio de Nonion sp. e E. gunteri, e coexistência de R. mangle, R. harrisonii and R. racemosa; (3) ecofácies 3, agrupando cinco amostras, com salinidade variando de água doce a mesohalina, amplo domínio de Miliammina fusca, e ocorrência de Rhizophora harrisonii e Rhizophora racemosa; (4) ecofácies 4, agrupando 3 amostras, em ambiente de água doce, onde foraminíferos são virtualmente ausentes. As associações de foraminíferos se mostraram uma eficiente ferramenta para reconhecimento das condições dominantes do complexo ambiente estuarino, onde os parâmetros abióticos são muito variáveis.

Texte intégralRésumé :
L’elaborato presenta una prima parte volta a fare chiarezza sulla letteratura presente riguardante la logistica e le operazioni interne al magazzino, come il ricevimento delle merci, lo stoccaggio, la preparazione degli ordini e la spedizione degli stessi.
In essa sono illustrate metodologie per analizzare i dati e le tecniche applicate per apportare miglioramenti al contesto aziendale.
Dopo aver fornito una panoramica teorica sul ruolo e la gestione delle scorte, si passa ad analizzare il problema dello stoccaggio dei prodotti finiti in una particolare realtà aziendale, come il deposito logistico di Mapei S.p.a. situato a Sassuolo, uno dei principali poli di distribuzione in Italia per l’intero gruppo, multinazionale del settore chimico per l’edilizia.
Esaminato il mercato di riferimento, il tipo di prodotto e il contesto in cui si trova ad operare, si passa all’analisi dell’as-is del magazzino.
Sono effettuate riflessioni su giacenze, consumi e rotazione dei prodotti con riferimento all’anno 2017.
Analizzando la situazione attuale sono emerse le criticità che caratterizzano il deposito e hanno spinto alla messa in atto delle attività di riorganizzazione.
Infine, vengono poste in risalto le proposte di miglioramento e le logiche che ne hanno guidato la creazione e quali aspetti positivi e negativi le caratterizzano.
Si confrontano le proposte di miglioramento realizzate con la situazione attuale focalizzandosi sulle distanze percorse dagli operatori per le attività di picking e preparazione degli ordini.
Nell’ultima parte dell’elaborato sono paragonate tra loro le proposte ideate e presentati i risultati ottenuti.

Texte intégralRésumé :
There are several industries exploring solutions to quickly and accurately digitize unexplored indoor environments, into useable three-dimensional databases. Unfortunately, there are inherent challenges to the indoor mapping process such as, scanning limitations and environment complexity, which require a specific application of tools to map an environment precisely with low cost and high speed. This thesis successfully demonstrates the design and implementation of a low cost mobile robotic computing platform with laser scanner, for quickly mapping with high resolution, urban and/or indoor environments using a gyro-enhanced orientation sensor and selectable levels of detail. In addition, a low cost alternative solution to three-dimensional laser scanning is presented, via a standard two-dimensional SICK proximity laser scanner mounted to a custom servo motor mount and controlled by external microcontroller. A software system to control the robot is presented, which incorporates and adheres to widely accepted software engineering guidelines and principles. An analysis of the overall system, including robot specifications, system capabilities, and justification for certain design decisions, are described in detail. Results of various open source software algorithms, as it applies to scan data and image data, are also compared; including evaluation of data correlation and registration techniques. In addition, laser scanner mapping tests, specifications, and capabilities are presented and analyzed. A sample design for converting the final scanned point cloud data to a database is presented and assessed. The results suggest the overall project yields a relatively high degree of accuracy and lower cost over most other existing systems surveyed, as well as, the potential for application of the system in other fields. The results also discuss thoughts for possible future research work.M.S.Cp.E.

Previous issue date: 2013-05-21This paper proposes to analyze the actions of a regular philanthropic school aimed at the intellectual growth and the development of students citizenship, at the pursuit of reducing the risk of school dropout, and at a path of quality education, which favor the continuity of the academic journey. To achieve these goals, could a program of continued education of teachers improve the learning perspectives of students in social vulnerability? Could a pedagogical tool that emerged from the meetings of this formation process facilitate an inclusive education? The methodology used in this study included a qualitative research with techniques of document analysis and literature review, which include the scientific works of Bourdieu, Freire, Hoffmann, Lahire, Morin, and Nóvoa. This dissertation presents the stages of the Learning Method through Rational-Emotional-Intuitive Research (MAPREI, in Portuguese), a pedagogical tool created by the teachers of this school, which has assisted in the challenge of engaging the student in the dynamic process of his/her own learning, with the mediating action of the teacher and the encouragement for a critical and solidarity-based knowledge
Este trabalho propõe-se a analisar ações de uma instituição escolar regular filantrópica, voltadas ao crescimento intelectual e ao desenvolvimento da cidadania de estudantes, pela busca da diminuição do risco de evasão escolar e do caminho de um ensino de qualidade, favorecedores da continuidade da trajetória acadêmica. Para alcançar esses objetivos, um programa de formação contínua de professores poderia melhorar as perspectivas de aprendizagem de alunos em situação de vulnerabilidade social? Uma ferramenta pedagógica surgida dos encontros dessa formação seria facilitadora de uma educação inclusiva? A pesquisa qualitativa foi a metodologia utilizada, com técnicas de análise documental e revisão bibliográfica, que inclui os trabalhos científicos de Bourdieu, Freire, Hoffmann, Lahire, Morin e Nóvoa. Esta dissertação apresenta as etapas do Método de Aprendizagem por Pesquisa Racional, Emocional e Intuitiva (MAPREI), ferramenta pedagógica criada pelos professores dessa escola, que tem auxiliado no desafio de envolver o educando no processo dinâmico de sua própria aprendizagem, com ação mediadora do professor e incentivo a um saber crítico e solidário

Nesse trabalho, dizemos e mostramos, por um caminho “desestruturalizado”, quer dizer, um caminho não linear pelos padrões da Academia, que a escola é uma farsa! Bebemos na fonte de Deleuze (1988), que apresenta a palavra aprender como verbo, ou seja, como a ação na qual o indivíduo toma para si o conhecimento. Para uma aproximação do processo de pensar e de aprender a Matemática Escolar foram utilizados cartografias e mapas narrativos. Elaborados a partir da imersão de seis meses dentro de uma escola estadual, no interior paulista, pudemos observar uma turma do segundo ano do Ensino Médio onde alguns alunos utilizam o YouTube e WhatsApp para tirar dúvidas de Matemática. Outro ponto que levantamos foram quais práticas e táticas que a professora utilizava dentro de sala de aula. Outra prática encontrada na escola consistia na ausência de alunos às sextas-feiras. Observamos também que era “natural” ter mapa de sala de aula e o uso do uniforme. Pudemos observar que não foi somente Matemática que os alunos aprenderam nessa classe. Aprendiam “normas”, “regras”, “classificações” e “subjetivações”. Apresentamos práticas de insurreições ao poder instituído. Para descrever os movimentos descritos acima foram realizadas entrevistas com oito alunos e dados do nosso diário de campo.

Cartographies and narrative maps were used to approximate the process of thinking and learning in School Mathematics. Elaborated from the immersion of six months within a state school in the inland of São Paulo, we could observe a second year high school class where some students use YouTube and WhatsApp to ask questions about Mathematics. Another point that we raised was what practices and tactics the teacher used within the classroom. Another practice found at the school was the absence of students on Fridays. We also noted that it was "natural" to have a classroom map and the use of a uniform. We could observe that it was not only math that students learned in this class.

Texte intégralRésumé :
La zone aride du nord du mexique est essentiellement exploitee par un pastoralisme incontrole (surpaturage), d'ou des risques de degradation de ce milieu tres fragile. Dans le but d'ameliorer la connaissance scientifique de ce milieu mal connu jusqu'a present, le present travail cherche a caracteriser le fonctionnement hydrique d'une fraction representative de cette zone, par le biais d'une etude experimentale du cycle terrestre de l'eau, et a en etudier les consequences sur le milieu, en particulier sur les sols. Le paysage est organise en plusieurs systemes ecologiques emboites qui se differencient par des caracteristiques propres de geomorphologie, pedologie, vegetation et hydrologie. Certains de ces systemes s'individualisent nettement par la couverture vegetale qui se distribue de maniere tres contractee sous forme d'une mosaique de plages denses alternant avec des zones totalement denudees a croute superficielle. La pluviometrie se caracterise par sa forte variabilite a la fois spatiale et temporelle. Deux types de milieux peuvent etre distingues, l'un a comportement infiltrant, l'autre a comportement ruisselant. Le premier correspond aux formations vegetales denses et represente 15% de la superficie. Le second correspond aux zones denudees a croute superficielle generalisee representant 85% de la superficie. Ces dernieres sont ainsi des zones de transit superficiel pour l'eau (impluviums) ou la dynamique hydrique est essentiellement horizontale. La faible quantite d'eau qui s'infiltre dans ces milieux reste proche de la surface, d'ou son evaporation tres rapide. Les ruissellements provenant des zones denudees sont interceptes par les plages de vegetation dense ou l'absence de croute favorise une importante infiltration. Cette dynamique hydrique verticale permet ainsi un stockage qui atteint en moyenne deux fois la pluviometrie recue. Ce fonctionnement hydrique determine la differenciation pedologique. Ainsi, aux zones denudees sont associes les sols non ou peu differencies, alors qu'aux plages de vegetation dense sont associes les sols les plus differencies. Ces derniers se caracterisent par une forte teneur de l'horizon b en smectite supergene provenant de l'alteration des smectites sedimentaires de la roche-mere. Cette neoformation est a mettre en liaison avec l'important apport en eau que recoivent ces sols. Pour assurer la perennite de quelques systemes ecologiques, le milieu est oblige d'autosteriliser une portion tres importante de sa superficie. Le surpaturage actuel ne fait qu'augmenter les surfaces steriles, ce qui accentue la desertisation

Texte intégralRésumé :
La presente tesis tiene como objetivo determinar el impacto en la satisfacción del cliente interno después de la implementación de una guardería institucional en la empresa Mapfre.
Según estudios realizados, en el Perú cada vez más mujeres están inmersas en el mundo laboral; el Instituto Nacional de Estadística e Informática, indica que en los últimos diez años la participación de las mujeres en el mercado laboral se ha incrementado en un 23.2% (INEI: 2016), con ello se da lugar a un contexto laboral competitivo, donde hombres y mujeres aspiran por desarrollarse profesionalmente. Sin embargo, esto se dificulta cuando son padres, ya que con la llegada de los hijos se ven en la necesidad de dejar de trabajar o continuar con sus labores profesionales siempre y cuando cuenten con el apoyo de alguien.
No contar con apoyo para el cuidado de los hijos, deriva en problemas familiares y laborales, lo que reduce el rendimiento de ellas en el trabajo o propicia el abandono de su empleo.
Tanto padres como madres con este tipo de problemas buscan equilibrar la vida laboral y familiar, además de pasar más tiempo con sus hijos. Otros estudios señalan que un 43% de mujeres renuncian a sus empleos antes de que su hijo cumpla un año por los problemas a las que se enfrentan, esto genera para la empresa una gran pérdida de inversión por las liquidaciones salariales, contrataciones y capacitaciones.
A nivel mundial empresas importantes aplican estrategias para que los colaboradores no abandonen sus puestos de trabajo. Por ejemplo, Netflix es la primera compañía que ofrece un año de maternidad y paternidad con sueldo fijo; Facebook, Google y Amazon, también ofrecen periodos largos de maternidad y paternidad, todas estas organizaciones se convirtieron en empresas con un mejor desempeño en 2017. En el Perú, Danper tiene una guardería desde abril del 2011 para atender más de 20 niños de madres trabajadoras y Telefónica también cuenta con una guardería en uno de sus locales. Buenaventura también tiene entre sus proyectos implementar una guardería, con el objetivo de incrementar la presencia del género femenino en el ámbito laboral.
El estudio también demostró que la implementación de una guardería como parte de los beneficios de la empresa recupera costos anuales generados por el ausentismo y la alta rotación del personal. Los padres con hijos a quienes se les realizó el estudio de mercado – mediante encuestas, focus group y encuestas a profundidad – tendrían menos probabilidades de renunciar y ausentarse, mejorarían su desempeño, reducirían el estrés, fortalecerán su desarrollo familiar y tendrían un mayor sentido de pertenencia a la compañía.
Un factor importante que respalda la tesis es que este año, el Pleno del Congreso, aprobó el proyecto de ley que propone establecer el derecho a cuidado de menores en salas cunas y guarderías en empresas del sector privado.
El proyecto de ley obliga a todas las entidades públicas y privadas laborales instalar salas de cuidado y guarderías en los centros de trabajo.
Finalmente, los análisis realizados en la investigación justificaron que la propuesta de la creación de una guardería institucional en Mapfre impactará de manera positiva la relación interna de los trabajadores.The objective of this thesis is to determine the impact on internal customer satisfaction after the implementation of an institutional nursery at Mapfre. According to studies, more and more women in Peru are immersed in the world of work; The National Institute of Statistics and Informatics indicates that in the last ten years the participation of women in the labor market has increased by 23.2% (INEI: 2016), this gives rise to a competitive labor context, where men and women aspire to develop professionally. However, this becomes difficult when they are parents, since with the arrival of the children they find it necessary to stop working or continue with their professional work as long as they have someone's support. Not having support for the care of children leads to family and work problems, which reduces their performance at work or leads to the abandonment of their employment. Both parents with these types of problems seek to balance work and family life, in addition to spending more time with their children. Other studies indicate that 43% of women quit their jobs before their child turns one year because of the problems they face, this generates for the company a great loss of investment due to salary settlements, hiring and training. Globally, important companies apply strategies so that employees do not leave their jobs. For example, Netflix is the first company to offer a year of maternity and paternity with a fixed salary; Facebook, Google and Amazon, also offer long periods of maternity and paternity, all these organizations became companies with better performance in 2017. In Peru, Danper has a nursery since April 2011 to serve more than 20 children of working mothers and Telefónica also has a nursery in one of its premises. Buenaventura also has among its projects to implement a nursery, with the aim of increasing the presence of the female gender in the workplace. The study also showed that the implementation of a nursery as part of the company's benefits recovers annual costs generated by absenteeism and high turnover of staff. Parents with children who underwent market research - through surveys, focus groups and in-depth surveys - would be less likely to give up and be absent, improve their performance, reduce stress, strengthen their family development and have a greater sense of Company membership. An important factor that supports the thesis is that this year, the Plenary Session of Congress approved a bill that proposes to establish the right to care for children in nursery rooms in private sector companies. This law requires all public and private labor entities to install care rooms and nurseries in the workplace. Finally, the analysis carried out in the investigation justified that the proposal for the creation of an institutional nursery in Mapfre will have a positive impact on the internal relationship of the workers.

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Finance from the NOVA – School of Business and EconomicsThis report provides a preliminary analysis and evaluation of the current situation of Mapfre Assistance Portugal in terms of productivity, performance, processes and need of implementing the ISO 9001:2008 standards for the assistance service (call-center). The decision about focusing on this part of the group of activities that compound the whole services and products is mainly addressed to the fact that this process is vital when talking about reducing or avoiding unnecessary costs. Thus, the study focuses on the performance in terms of services rendered, files opened, turnover along the years and complaints, as well as the analysis of the flow of process (call center) along with some statistics about ISO 9000, ISO 9001 and related data from competitors. The results showed that the processes are going accordingly with the expectations of the company as the number of complaints is low compared with the turnover, the services required have no high variations and productivity levels are significantly positive. This happens even when there are not documented records of the procedures that could contribute with the effective allocation of work and activities.The report concludes that the possibility of Mapfre Assistance Portugal entering in a ISO 9001:2008 certification process is low, since the costs of certification are higher than the benefits that might arise, given the present strategic objectives that Mapfre Asistencia in Portugal is following, the economic situation of the country and the perception of ISO certifications in the sector and the country itself. The strategies of the company would require the use of different tools and the planning of different strategies towards the accomplishment of the general targets of the group (Mapfre Asistencia). Thus, the recommendations are addressed more towards to policies that increase and improve the net of providers which can meet requirements and expectations from customers about solving issues related to greater speed and reliability. Therefore, relation management strategies will be more appropriate since allow the company to get to know the needs of different actors, namely: customers, suppliers, employees and managers; and finally keep focused on internal control in order to improve the dimensions rated as low by customers.

Characterization of DAP1/YPL170W: the Saccharomyces cerevisiae Membrane Associated Progesterone Receptor (MAPR) Homologue

Directed by Dr. Jung H. Choi
MAPRs (Membrane Associated Progesterone Receptors) from several sources have been isolated, studied and minimally characterized in mammalian systems, yet the specific role of this protein family has not been fully determined. Early worked characterized this protein family as a type of steroid binding protein, unrelated to the classical nuclear receptors, and linked this family to non-genomic cellular responses. The MAPR homologues as a group have been suggested to play widely varying roles from axon guidance and neuronal formation, to steroid hydroxylation, to influencing reproductive behavior. Their specific role has not yet been clearly demonstrated in any organism. There is some debate as to whether MAPRs do indeed bind steroid compounds, but there is clear evidence this family of proteins is involved in steroid perception. Recent work has begun to link a specific member of the MAPR family, IZAg from rat, to steroid metabolism/production, specifically, in the hydroxylation step of glucocorticoid production from progesterone. In the yeast Saccharomyces cerevisiae, the MAPR homologue is DAP1. Preliminary work on haploid strains demonstrated several phenotypes associated with the DAP1 deletion mutant, most notably an altered sterol profile. Previous characterization of diploid homozygous mutant strain has shown a differential sensitivity to alcohol, an altered sterol profile, and a strong yeast two-hybrid interaction with Ypr118wp; methylthioribose-1-phosphate isomerase. Work in this study link the localization of Dap1p to lipid particles and on the ER, both sites of sterol synthesis. The sterol profiles of the control strain and the dap1Ġdeletion mutant strain were examined in detail. The most notable difference was the presence of an additional sterol compound associated with the deletion mutant strain. The structure of this compound does not correspond to normal sterols in the ergosterol biosynthetic pathway, but does correspond to structure of sterols in so-called alternate aberrant sterol pathways. The data presented in this study demonstrates that Dap1p was involved in sterol processing, although its specific role is unknown. Two possible scenarios are proposed; one where Dap1p is involved in regulating the flux of sterols from one internal membrane to another, and another where Dap1p is involved in aberrant sterol pathways.

Este estudo é parte de uma proposta mais abrangente intitulada Cultivo do mapará e do camarão-da-amazônia em sistemas multiespaciais e multitróficos. Esta proposta é uma parceria entre o Centro de Aquicultura da Universidade Estadual Paulista (CAUNESP), a Fundação de Amparo à Pesquisa do Estado de São Paulo e Empresa Vale do Rio Doce (Parceria para Inovação Tecnológica - PITE). Na proposta inicial, mais abrangente e com diversos outros pesquisadores envolvidos, estavam previstas a execução de três subprojetos que tinham como objetivo final desenvolver conhecimento e tecnologia para desenvolver sistemas sustentáveis para a produção aquícola de mapará e do camarão-da-amazônia com uma abordagem ecossistêmica. Assim, a este estudo coube realizar, inicialmente, as primeiras tentativas de domesticar e transportar o mapará para viveiros de reprodutores localizados no CAUNESP. Por se tratar de uma proposta inédita de bioprospecção não era possível prever a resposta do mapará frente às tentativas de domesticá-lo, pois mesmo sendo intensamente explorado, não existia sequer uma única informação sobre seu cultivo. A espécie se mostrou extremamente sensível ao manejo, o que nos fez tentar substituir o transporte de reprodutores por tentativas de indução à desova de matrizes selvagens nos locais de desova (sendo este um dos temas desta tese desde o início). Assim, neste estudo, focamos em dois principais objetivos: o ciclo reprodutivo da espécie (manuscrito I) e a padronização de um protocolo para sua desova induzida (manuscrito II). Esta tese é então composta por dois manuscritos, sendo que o primeiro gerou informações para a execução do segundo. A escassez de informações e o problema com barragens na região do estudo nos levou a permear assuntos, necessários, mas não antes previstos, como a interrupção de rotas migratórias, o impacto da barragem sobre a população do mapará e sobre...
This study is part of a broader proposal entitled Culture of mapará and Amazon shrimp in multiespaciais and multitrophic systems. This proposal is a partnership between the Aquaculture Center of the São Paulo State University (CAUNESP), the Foundation for Research of the State of São Paulo and Company of Vale do Rio Doce (Partnership for Technological Innovation - PITE).

Resumo: Este estudo é parte de uma proposta mais abrangente intitulada "Cultivo do mapará e do camarão-da-amazônia em sistemas multiespaciais e multitróficos". Esta proposta é uma parceria entre o Centro de Aquicultura da Universidade Estadual Paulista (CAUNESP), a Fundação de Amparo à Pesquisa do Estado de São Paulo e Empresa Vale do Rio Doce (Parceria para Inovação Tecnológica - PITE). Na proposta inicial, mais abrangente e com diversos outros pesquisadores envolvidos, estavam previstas a execução de três subprojetos que tinham como objetivo final desenvolver conhecimento e tecnologia para desenvolver sistemas sustentáveis para a produção aquícola de mapará e do camarão-da-amazônia com uma abordagem ecossistêmica. Assim, a este estudo coube realizar, inicialmente, as primeiras tentativas de domesticar e transportar o mapará para viveiros de reprodutores localizados no CAUNESP. Por se tratar de uma proposta inédita de bioprospecção não era possível prever a resposta do mapará frente às tentativas de domesticá-lo, pois mesmo sendo intensamente explorado, não existia sequer uma única informação sobre seu cultivo. A espécie se mostrou extremamente sensível ao manejo, o que nos fez tentar substituir o transporte de reprodutores por tentativas de indução à desova de matrizes selvagens nos locais de desova (sendo este um dos temas desta tese desde o início). Assim, neste estudo, focamos em dois principais objetivos: o ciclo reprodutivo da espécie (manuscrito I) e a padronização de um protocolo para sua desova induzida (manuscrito II). Esta tese é então composta por dois manuscritos, sendo que o primeiro gerou informações para a execução do segundo. A escassez de informações e o problema com barragens na região do estudo nos levou a permear assuntos, necessários, mas não antes previstos, como a interrupção de rotas migratórias, o impacto da barragem sobre a população do mapará e sobre...

Texte intégralRésumé :
L'instrument EUSO-Balloon est un prototype pour le télescope JEM-EUSO, destiné à observer pour la première fois depuis l’espace les gerbes atmosphériques induites par les rayons cosmiques d'ultra-haute énergie. Le principe de détection repose sur la mesure des photons émis par la fluorescence de l’atmosphère terrestre lors du développement des gerbes. EUSO-Balloon, un télescope UV embarqué à bord d’un ballon stratosphérique, a pour but de prouver la pertinence des concepts instrumentaux développés dans le cadre du projet JEM-EUSO. Cette thèse est dédiée en grande partie à l’assemblage, l’intégration et les tests du module de photo-détection d’EUSO-Balloon. Il s’agit d’un ensemble de 36 tubes photomultiplicateurs multi-anodes, pour un total de 2304 pixels, et d’une électronique de lecture permettant d’imager le développement, s’effectuant à la vitesse de la lumière, des gerbes atmosphériques. Cette caméra permet ainsi de réaliser des images de 2,5 microsecondes avec une sensibilité au photo-électron unique. Il aura été démontré que la mesure de l’efficacité de photo-détection de la caméra est réalisable avec une précision inférieure à 5% pour la tension de polarisation adaptée. EUSO-Balloon a effectué son premier vol en août 2014 lors duquel il a été prouvé, grâce à l’utilisation d’événements simulés par tirs lasers, qu’il est possible d’imager le développement de gerbes atmosphériques depuis le proche espace. Les données enregistrées permettent de réaliser une étude sur le bruit de fond UV produit par l’atmosphère terrestre. L’ensemble du travail d’assemblage, d’intégration et de test permet d’envisager les développements pour les futures missionsThe EUSO-Balloon instrument is a prototype for the JEM-EUSO telescope, intended to observe for the first time from space the extensive air showers (EAS) induced by the ultra-high energy cosmic rays. The detection technique relies on the measurement of the photons produced by the fluorescence of the Earth’s atmosphere when EAS develop. EUSO-Balloon, a UV telescope payload of a stratospheric balloon, has the objective to prove the relevance of the concepts developed for the JEM-EUSO project. An important part of this thesis is devoted to the assembly, the integration and the test of the EUSO-Balloon’s photo-detection module. It is an array of 36 multi-anodes photo-multiplier tubes, for a total of 2,304 pixels, and of a readout electronics able to image the development at the speed of the light of the EAS. It has a framing time of 2.5 microseconds with a single photo-electron sensitivity. It has been proved that the photo-detection efficiency of this camera can be measured with an accuracy better than 5% for the proper polarization voltage. The first flight of EUSO-Balloon happened in August 2014 and proved, with the use of laser induced events, that air showers can be imaged for the near space. Data acquired during this flight allow to study the UV background originating from the Earth’s atmosphere. The assembly, integration and test work provided during this project leads the development of future missions

Previous issue date: 2006-07-28The Amazon region has around 40 species of fishes being explored and commercialized daily, especially in markets and fairs. Fisheries are basically artisanal, directed towards a small number of species, causing the over exploitation of certain fishing stocks. However, some species have certain characteristics for farming, which would help diminish the fishing pressure over these species. With the objective of identifying new species for farming, fishing variables were analyzed from the V?rzea Natural Resource Management Project s data base. The gathering of information took in consideration the years from 2001 to 2004, allowing the identification of fisheries captured along the main channel of the Amazon river. Data analyses revealed that the 10 main most captured fish categories, were responsible for 82,46% of the total volume captured in the state of Amazonas, with special reference to the order of the Characiforms, representing 78,34% of the captures. The abundance of fishery resources depends directly on the environmental variations (inundation), fact that contributes to the oscillation of the price and inconstancy of the availability some species of fishes during the flooded season. Fish farming can precisely compensate this need of the market and dilute the pressure over the natural stocks. The informations obtained from ProV?rzea/Ibama about fish farming data in the State and the fisheries exportation of fisheries, gathered from SEAP/PR and Fishery Resource Center of Ibama/AM, the aruan? and mapar? can be pointed out as species with farming potential. The analyzes involving captur per unit effort revealed a productivity of 11-20 Kg/Fisherman/Day for the aruan?, which is the fifth category most captured in the state (3,83% of the total) and the seventh of the exportation list; and 21-31 Kg/Fisherman/Day for the mapar?, tenth most captured species and the third in terms of exportation. The analyses of carcass profit and chemical composition and quality of fishes, revealed that the carnivorous aruan?, captured mainly in the dry season and that had its filet as the main commercialized product, presented a profit of 29,15 ? 1,48%, with the chemical analyses, characterizing it as a low fat fish (0,08%) with high protein value (15,19 %). The planktophagous mapar?, captured throughout the year, presented a profit of its filet of 53,04 ? 1,40% and the chemical analyses allowed the classification of this fish as fat (21,21% fat) with low protein value (12,85 %).
A regi?o Amaz?nica possui cerca de 40 esp?cies de peixes sendo exploradas e comercializadas diariamente, nos principais mercados e feiras. A pesca na regi?o ? basicamente artesanal, direcionada a um n?mero diminuto de esp?cies, causando uma sobreexplota??o em determinados estoques pesqueiros. No entanto, algumas esp?cies apresentam caracter?sticas para serem criadas em cativeiro, o que ajudaria a diminuir a press?o da pesca sobre as mesmas. Com o objetivo de identificar novas esp?cies para a cria??o em cativeiro, foram analisadas vari?veis pesqueiras a partir do banco de dados central do Projeto Manejo dos Recursos Naturais da V?rzea, sendo utilizado os dados de 2001 a 2004, permitindo a identifica??o dos pescados mais capturados na calha do Rio Solim?es/Amazonas. A an?lise dos dados revelou que as 10 primeiras categorias de pescado mais capturadas correspondiam em m?dia 82,46% do volume total capturado no estado do Amazonas, destacando-se a ordem dos Characiformes, com 78,34% das capturas. A abund?ncia de pescado depende diretamente das varia??es ocorridas no ambiente (pulso de inunda??o), fato este que contribui para oscila??o no pre?o e inconst?ncia de oferta de algumas esp?cies de pescado durante o per?odo de cheia. A piscicultura poder? vir justamente suprir esta car?ncia do mercado e diluir a press?o nos estoques naturais. As informa??es obtidas no ProV?rzea/Ibama juntamente com os dados de piscicultura do estado e da exporta??o de pescado, levantados junto a SEAP/PR e N?cleo de Recursos Pesqueiros do Ibama/AM destacaram-se o aruan? e o mapar? como esp?cies potenciais para a piscicultura. As an?lises envolvendo a captura por unidade de esfor?o revelaram uma produtividade de 11-20 Kg/pescador/dia para o aruan?, que ? a quinta categoria mais capturada no estado (3,83% do total) e a s?tima na lista de exporta??o; e 21-31 Kg/pescador/dia para o mapar?, d?cima categoria mais capturada e a terceira na lista de exporta??o. J? as an?lises de rendimento de carca?a e da composi??o qu?mica e da qualidade do pescado, revelaram que o carn?voro aruan?, capturado basicamente na seca e que teve seu fil? como principal produto comercializado, apresentou um rendimento de 29,15 ? 1,48%, com as an?lises qu?micas que o caracterizam como um pescado magro (0,08% gordura) com alto teor prot?ico (15,19 %PB). O planct?fago mapar?, despescado ao longo de todo ano, apresentou um rendimento de fil? de 53,04 ? 1,40% e a an?lise qu?mica permitiu classificar este pescado como gordo (21,21% de gordura) e de baixo valor prot?ico (12,85 %PB).

Texte intégralRésumé :
Subatomic particles interaction have been the main goal of high energy physics. Worldwide experimental facilities use different techniques to improve the knowledge of the elementary components of the nature around us. Many experiments have been built during the years with a continuously improving technology to boost the precision with which detect new particles and structures.
This work is focused on the photon detectors for a newer and innovative Ring Imaging CHerenkov detector (RICH). It is the most recent development of the so-called CLAS12 experiment. CLAS12 it is the acronym for CEBAF (Continuous Electron Beam Accelerator Facility) Large Acceptance Spectrometer at 12 GeV and it is an experiment hosted by the Thomas Jefferson National Accelerator Facility (JLAB). It is the follower of the old CLAS experiment built for the 6 GeV electron beam energy. The JLAB facility has recently been upgraded together with all the experiments involved in it, to double the beam energy and increase by orders of magnitude the luminosity. For this upgrade the CLAS12 collaboration decided to replace one of the already existing gas Cherenkov detector with the RICH in order to improve detection capabilities over the wider range of momentum achievable with the new beam.
The RICH detector will be composed of two modules having similar geometry. They will both have an hybrid optic design to satisfy performance requirements and geometrical constraints: small dead space, low dead time, high spatial and time resolutions. For the active part, two different photon detector have been chosen: the first module, already installed, is based on Multi-Anode PhotoMultiplier Tubes (MAPMTs) while the second one, to be ready in few years, will be build with Silicon PhotoMultiplier (SiPM).
The CLAS12 RICH is the first to use flat panel MAPMTs of large area. A dedicated front-end electronics has been developed for the readout of this kind of sensors, to enable single photon detection. In this thesis, the author's contribution to the study step that preceded the active component's installation on the first sector of the detector are presented: preparation of the laser setup for the characterization of all the final components (sensors and electronics), analysis of the collected data to extract a set of parameters that optimizes the performance of the MAPMTs during the physics runs and definition of a set of performance indicators to be used as a reference during calibration run.
The author's work continues with the photon sensor studies for the second sector that will be installed in the next future. Although SiPMs have never been used in Cherenkov application, the rapid evolution in their production technology has lately opened interesting opportunities. The test to validate the SiPM use in the CLAS12 environment are described starting from the irradiation test, introducing a detailed study of the dark counts, dedicated to the characterization of the non trivial detector background. A preliminary test of the single photon detection capability of novel SiPM matrices in conjunction with the RICH readout electronics is also shown to validate their use togheter.
As a completion of the author's work, the photon detector assembling and commissioning is described. A dedicated setup was developed to test the photon detector with cosmic muons, in a configuration mimicking the one in the experimental hall. This allowed to test the correct mapping of the detector and the timing precision.
This work concentrates on the validation, characterization and commissioning of novel photon sensors for the challenging Cherenkov application, that requires single photon capability. It has lead to the installation of the first RICH sector that is now installed and running in the CLAS12 experiment and the validation of SiPM use in the single photon regime for the second RICH module at the moderate radiation levels foreseen in the experimental Hall B at JLAB.Lo scopo principale della fisica delle alte energie è investigare la struttura subatomica della natura che ci circonda. Per farlo, molti laboratori ed esperimenti usano diverse tecniche di rivelazione, sfruttando il continuo sviluppo tecnologico, per raggiungere sempre nuovi livelli di precisione per rivelare nuove particelle. Il lavoro presentato si interessa dei rivelatori di fotoni per un innovativo rivelatore Ring Imaging CHerenkov che fa parte del potenziamento dell'esperimento CLAS12: CEBAF (Continuous Electron Beam Accelerator) Large Acceptance Spectrometer at 12 GeV. Questo esperimento si trova presso il laboratorio nazionale Thomas Jefferson ed è il proseguimento del precedente esperimento, CLAS, che usufruiva del fascio di elettroni a 6 GeV. Il laboratorio ha recentemente completato il potenziamento della strumentazione per raddoppiare l'energia del fascio e aumentare la luminosità. La collaborazione in questa fase ha deciso di sostituire una parte del rivelatore Cherenkov a gas con il RICH per poter migliorare le capacità di rivelazione in un intervallo più ampio di energie. Il rivelatore sarà composto da due moduli progettati con un disegno ottico ibrido per poter soddisfare le specifiche di prestazione e i vincoli geometrici dell'esperimento: massimizzazione dell'area attiva di rivelazione, minimizzazione di tempi morti dell'elettronica, alte risoluzioni spaziali e temporali. Sono però stati scelti due rivelatori di fotoni diversi, seguendone principalmente lo sviluppo tecnologico: il primo modulo, già installato, è basato sulla tecnologia matura dei tubi fotomoltiplicatori a multi anodo (MAPMT), mentre il secondo, pronto tra pochi anni, utilizzerà una soluzione innovativa e monterà fotomoltiplicatori al silicio (SiPM). Il RICH di CLAS12 è il primo rivelatore ad utilizzare fotomoltiplicatori a multi anodo di grande area per coprire un’ampia superficie. Per poter lavorare in condizioni di singolo fotone è stata sviluppata un specifica elettronica di front-end. In questo lavoro verranno presentate le diverse fasi che hanno anticipato l'istallazione nella sala sperimentale: preparazione di tutte le componenti (sensori e schede di elettronica) per la caratterizzazione, l'analisi dei dati collezionati in questa fase per definire i parametri di lavoro ottimali durante i run di fisica e preparazione di un set di indicatori di rifermento da confrontare con i futuri dati estratti dai run di calibrazione dell'esperimento. La seconda parte del lavoro riguarda il settore del RICH che verrà installato nel prossimo futuro e che, sfruttando la loro rapida evoluzione tecnologica, prevede l'utilizzo dei SiPM. Gli studi per validare il loro uso in condizioni di singolo fotone sono stati fatti, e presentati in questo documento, a partire da un test di irraggiamento con lo sviluppo di un'analisi ad-hoc per lo studio approfondito del rumore di fondo. Inoltre sono presentati anche i test preliminari fatti per studiare il comportamento delle matrici di SiPM connesse con l'attuale elettronica di lettura del segnale sviluppata appositamente per il RICH. Infine viene descritto il processo di assemblaggio e di messa in opera del rivelatore finale. Un test per lavorare con i raggi cosmici e simulare le condizioni finali di lavoro del foto-rivelatore è stato realizzato prima dell’installazione all’interno del modulo RICH. Questo ha permesso di fare una verifica della mappatura del rivelatore e della risoluzione temporale. Questo lavoro si è concentrato su validazione, caratterizzazione e messa in opera di rivelatori di fotoni innovativi per applicazioni Cherenkov in condizioni di singolo fotone. I risultati ottenuti hanno portato ad installare con successo il primo settore del RICH che ora sta già prendendo dati nell'esperimento e a validare l'utilizzo dei SiPM per il secondo settore ai livelli di radiazione attesi nella sala sperimentale del laboratorio.

Texte intégralRésumé :
El concepto de lealtad de la marca ha sido siempre un área muy importante para los profesionales del marketing y más aun en el mercado de categorías de producto tan nuevas para los clientes y tan competitivas para las empresas como lo es el de dispositivos de seguridad para el hogar.
El objetivo del presente estudio es determinar si existe relación entre los beneficios de las redes sociales y la lealtad de los clientes hacia las marcas. Se utilizó un cuestionario para recopilar datos (n = 384) de los clientes de las tres principales empresas de seguridad para el hogar en el Perú, Prosegur, Verisure y Mapfre.
El análisis de correlaciones de las variables utilizadas en la investigación se utilizó para medir si existe relación entre los beneficios de las redes sociales y la lealtad de los usuarios. Los resultados demuestran que los beneficios de las redes sociales en conjunto tienen relación con la lealtad de los clientes del sector sistemas de seguridad para el hogar. Sin embargo, algunos beneficios de las redes sociales como la interacción, demostró tener baja relación con la lealtad de marca. El estudio recomienda que las empresas del sector seguridad para el hogar comprendan y evalúen a profundidad los benefcios que ofrecen las redes sociales e identificar cuales son más relevantes para sus clientes. Un punto de mejora para las empresas del sector seguridad para el hogar es la posibilidad de desarrollar una mejor estrategia de comunicación que les permita distinguirse en alguno de los atributos que ofrecen las redes sociales.The concept of brand loyalty has always been a very important area for marketing professionals and even more so in the market, product categories as new for customers and as competitive for companies as that of home security devices. The objective of this study is to identify the role of social media and its relation on customer loyalty to brands, understanding the relationship between the benefits that social media offers to customers. A questionnaire was used to collect data (n = 384) from clients of the three main home security companies in Peru, Prosegur, Verisure and Mapfre. The correlation analysis of the variables used in the research was used to measure the relation between the benefits of social networks and the level of loyalty of the users. The results show that the benefits of social networks as a whole have a direct effect on the loyalty of customers in the home security systems sector. However, some benefits of social networks such as interaction proved to have less relation on the level of brand loyalty. The study recommends that companies in the home security sector understand and evaluate in depth the benefits offered by social networks and identify which ones are most relevant to your clients. A point of improvement for companies in the home security sector is the possibility of developing a better communication strategy that allows them to distinguish themselves in one of the attributes offered by social networks.

Hypophthalmus marginatus é um siluriforme, pertencente à família Pimelodidae. Na Amazônia oriental esta espécie é altamente consumida, e possui uma grande importância sócio-econômica para a região. Estudo da caracterização histológica do sistema reprodutivo ainda é desconhecido nesta espécie. Portanto, este estudo serve de ferramenta para as técnicas de biotecnologia, necessárias para a produção em cativeiro, visto que a espécie é um dos recursos pesqueiro mais explorado pela pesca artesanal. O objetivo do presente estudo foi estudar aspecto estrutural e ultraestrutural das células do epitélio germinativo de Hypophthalmus marginatus durante a espermatogênese. Foram capturados 168 espécimes no período entre dezembro de 2011 a dezembro de 2012. Macroscopicamente foram identificados 69 machos adultos, ainda em campo foi realizada uma incisão ventral e fragmentos da região mediana dos testículos e sêmen foram retirados e submetidos ao processamento e análise em microscopia de luz, microscopia eletrônica de transmissão e varredura. Os estudos evidenciaram que as células germinativas se proliferam no interior do cisto espermático de forma sincrônica. As espermátides entram no processo de espermiogênese passando por três fases distintas de diferenciação celular. O núcleo não se move em relação ao eixo flagelar e os centríolos não migram para o núcleo. Os espermatozóides liberados no lúmen do túbulo seminífero apresentaram uma cabeça esférica com o núcleo altamente condensado e sem acrossoma, a peça intermediária curta contendo um único flagelo longo com axonema apresentando o microtúbulo padrão (9+2), a fossa nuclear excêntrica alojava parcialmente o centríolo proximal. A presença de células espermatogênicas na mesma subfase da meiose no interior do cisto é caracterizada como espermatogênese cística, com desenvolvimento sincrônico das células, Isto sugere que espermiogênese de H. marginatus seja do tipo III e a presença da fossa nuclear é considerada uma característica distinta para a espécie, o que difere de outros pimelodideos.
Hypophthalmus marginatus is a siluriforme, belonging to the family Pimelodidae. This species is highly consumed in eastern Amazonia and has a wide socio-economic importance to the region. Studies on the histological characterization of the reproductive system are still unknown in this species. Therefore, this study serves as a tool for biotechnology techniques, necessary for the production in captivity, since this species is one of the fishing resource most intensively exploited by artisanal fisheries. The aim of this study was to characterize the structural and ultrastructural features of germinal epithelium cells of Hypophthalmus marginatus during spermatogenesis. 168 specimens were collected from December 2011 to December 2012. Macroscopically were identified 69 adult males. In field, ventral incision was held in fishes and fragments of testicles from the median region and semen were removed. Then the material was subjected to processing and analysis of light microscopy, transmission electron microscopy and scanning. The data revealed that the germ cells proliferate inside the spermatic cyst synchronously. Spermatids enter at the spermiogenesis process through three distinct stages of cell differentiation. The nucleus does not move relative to the axis flagellar and the centrioles don't migrate to the nucleus. The spermatozoids showed a spherical head with the highly condensed nucleus and no acrosome. The intermediary piece was short containing a single long flagellum. The axoneme presents the structure of microtubules within the pattern (9 + 2). The nuclear fossa housed the proximal centriole partially. The presence of spermatogenic cells in the same subphase of meiosis inside the cyst is characterized as cystic spermatogenesis, with synchronous growth of the cells. This suggests that spermiogenesis of H. marginatus is of type III and the presence of nuclear fossa is considered a distinctive feature for the species, which differs from other pimelodids.

La présente Thèse en Intelligence Artificielle est basée sur un tout premier concept nommé “Assistant Conversationnel”, lequel est abordé par le fait qu'un utilisateur quelconque souhaitant joindre un interlocuteur doit pouvoir toujours voir sa requête se réaliser, quelque soit le moyen choisi par le terminal et sans que l'utilisateur ait à choisir lui-même le moyen adéquat. Le problème principal à résoudre se définit en conséquence par la modélisation et la conception d'une interface intelligente, personnalisée et praticable par tous les publics sur les terminaux de communication spécialisables accédant à Internet. Nous avons alors créé et développé de nouveaux procédés “intelligents”, chargés entre-autres de rendre les opérations courantes moins fastidieuses sur des applications de messagerie électronique. Pour cela, nous avons établi un état de l'art des divers terminaux de communication disponibles sur le marché mondial, ainsi qu'une classification taxinomique poussée et une nouvelle hiérarchisation efficace des interfaces intelligentes. Puis, nous avons construit un “Modèle Auto-Adaptable d'Utilisateur” sur un apprentissage comportemental, incrémental et évolutif, finalement implémenté en quatre phases : 1. Analyse, représentation et classification des différentes actions réalisées par l'utilisateur. 2. Proposition régulière à l'utilisateur d'effectuer de manière auto-adaptable les actions apprises. 3. Exécution auto-adaptable de ces différentes séquences d'actions répétitives. 4. Simplification auto-adaptable d'éventuelles “erreurs” ou incohérences de manipulation. Ainsi, cette contribution innovante à l'interfaçage homme-machine avancé a permis d'aboutir à la validation complète d'un logiciel intelligent de communication, tout-à-fait autonome et portable, capable d'assister chaque utilisateur, néophyte comme très expérimenté, dans ses divers travaux quotidiens, et ce de manière conviviale et toujours respectueuse de ses préférences.

Texte intégralRésumé :
La risonanza magnetica in diffusione è una delle uniche tecniche di imaging in grado di dare informazioni sulla struttura del cervello umano in-vivo. Tramite tecniche matematiche chiamate modelli di ricostruzione, dal segnale di diffusione, \`e possibile ricavare la funzione di distribuzione di probabilità dello spostamento delle molecole d'acqua in ogni voxel, detto propagatore. Dal propagatore è possibile ricavare informazioni riguardanti l'orientazione dei fasci di fibre neuronali, la densità di tali fibre e il calibro assonale, tramite il calcolo di particolari indici.Lo scopo principale di questa tesi è la caratterizzazione di tali indici, e in particolare la loro validazione tramite, sia simulazioni al computer, sia dati in-vivo. In particolare ci siamo concentrati sugli indici calcolati utilizzando tre modelli di ricostruzione: il DTI, il 3D-SHORE e il MAPMRI. Il primo contributo di questa tesi riguarda il calcolo e il confronto dei valori degli indici del propagatore per tali modelli. Il secondo contributo della tesi è lo studio della variazione degli indici rispetto alle principali variazioni microstrutturali, tipiche della materia bianca. Nella terza parte della tesi abbiamo proposto un nuovo modello di ricostruzione in grado di dare risultati pi\`u accurati nel caso di incrocio di fibre. Un'accurata rappresentazione degli incroci è fondamentale visto che rappresentano la maggior parte della materia bianca del cervello umano.L'ultimo contributo della tesi è lo sviluppo di un nuovo modello di ricostruzione del propagatore in grado di modellare acquisizioni con gradienti a tempi di diffusione multipli. I risultati mostrano come gli indici del propagatore siano estremamente sensibili a variazioni microstrutturali della densità e dell'orientazione degli assoni della materia bianca. Gli indici sono risultati invece insensibili a variazioni del diametro assonale, a causa del lento decadimento del segnale, che richiederebbe acquisizioni effettuate con campi magnetici estremamente elevati. I nuovi modelli di ricostruzione proposti hanno dato eccellenti risultati sia nella modellazione degli incroci di fibre che del segnale a tempi di diffusione multipli.Diffusion magnetic resonance imaging is one of the only non-invasive imaging technique which is able to provide information on the human brain structure in-vivo.From the diffusion signal, using mathematical techniques called reconstruction models, it is possible to retrieve the probability density function of the water molecules displacement, or ensemble average propagator (EAP). From the EAP, it is possible to calculate a series of indices which provide information regarding the fiber orientation, fiber density, and the average diameter of the axons. The main aim of this thesis is the characterization of these indices, and, in particular, their validation. In order to characterize the indices, we take advantage of computer simulation of diffusion in different media, as well as human brain acquisition. In particular, we focused on the EAP indices calculated using three EAP models: the DTI, the 3D-SHORE, and the MAPMRI. The first contribution of this thesis is the developing and the comparison of the values of the indices for the different models.The second contribution of the thesis is the study of the variation of the indices with respect to the principal microstructural parameters which characterize the white matter. The third contribution of the thesis is the proposal of a new reconstruction model designed to reconstruct accurately the EAP in the case of crossing fibers. The fourth contributions is the developing of a new tensor model, which is able to capture the dependence on the timing parameters of the diffusion signal.Results show the sensibility of the EAP-derived indices to microstructural variations such as the orientation dispersion of the axons and the density of the fibers. Diameter axons variation, on the contrary, are not measurable by the EAP indices because of the slow signal decay, which would require extremely high magnetic fields to be measured. The new reconstruction models proposed provide excellent results in the modeling of crossing fibers and multiple diffusion times, respectively.

“Mapart” utilizes the internet interface to introduce the concept of map space into the “Collaboration Creation”. Besides, it also allows all the people can obtain our membership freely to create their own maps; share them with other users to feel their living space and Utopia in mind virtually through this wonderful map making interface. In this process, what you have to do is following the interacting route exploration among them, and you can discover the abundant connection of human relations and interaction between the humans and lands. It is absolutely an amazing reading experience beyond our knowledge toward time and space! The world of art does exist in this realistic world! When you shift your realistic view into the artistic perspective, a whole new vision will automatically come out. Thus, “Mapart” intends to use the thinking way of “Erweiterter Kunstbegriff” to make people introspect the influences of the internet world, and further, take humans as the main body to think of the issue about “the human body in the realility”. This is a hundred percent non-commercial artistic creating project. Through the accurate location positioning capability of this unique Taiwan Power Company Grid system, we can put all the artistic ideas onto the postcards to present the true look of Taiwan after the individual subjective understanding and individual society are interacted.

Texte intégralRésumé :
O presente projecto tem como principal objectivo a revisão dos critérios do sistema de avaliação de desempenho na empresa MAPFRE. Para tal, foi importante, numa primeira fase, estudar e perceber o que é afinal a avaliação de desempenho. Assim, começou-se por compreender e desenvolver o verdadeiro conceito de avaliação de desempenho (de acordo com diversos autores), quais os seus objectivos, componentes e os erros a que este sistema está sujeito. Após esta primeira etapa partiu-se para o projecto propriamente dito onde foram recolhidos alguns dados necessários da empresa para poderem ser analisados, de forma a obtermos resultados concretos relativamente ao problema existente. Com efeito, foram recolhidas informações concretas a nível do sistema de avaliação de desempenho e da organização da própria empresa através de manuais existentes na MAPFRE e de uma pequena apresentação realizada por colaboradores do departamento de Recursos Humanos. Tembém foram recolhidas as ponderações atribuídas aos colaboradores, por item, e, por fim, foram efectuadas entrevistas a 8 colaboradores (4 chefes e 4 chefiados).
Assim, os dados foram analisados estatisticamente através do cálculo da média e desvio padrão, análise factorial, correlação item total se item apagado e realização de entrevistas (para obtermos uma maior percepção da opinião dos utilizadores relativamente ao sistema). É, então, nesta altura que nos deparamos com os erros cometidos na avaliação de desempenho bem como os critérios utilizados que poderão, posteriormente, ter de sofrer alterações. Por fim, proposemos algumas medidas de melhoramento, quer através de novos critérios, novas formas de avaliação quer a nível da formação dos avaliadores e avaliados.The main objective of this project is to revise the performance assessment system’s standards for MAPFRE. In order to do so, the fundamental starting point was to develop a deeper understanding of the conceptual meaning of performance assessment. Thus, the aim of this was to understand and develop the true concept of performance assessment (as per several authors), which are its objectives, components and the intrinsic errors to which this system is subject to. After this first stage, workings on the actual project commenced, by undertaking research and data gathering regarding the company, so that data analysis could be performed in order to obtain actual results on this matter. Specific data regarding performance assessment and companies’ organisation was gathered using MAPFRE’s text books and a small presentation prepared by the companies’ HR department employees. The employees’ ratings by item were also gathered and finally 8 people were interviewed (4 in-charge and 4 staff).Hence, the data was analysed by means of statistical methodologies, specifically through calculating average and standard deviation, factorial analysis, total item if deleted item correlation and through the undertaking of interviews (so that the opinion of the system users regarding its specificities could be perceived). Subsequently, we have developed a perception of the errors that occur within performance assessment, as well as within the standards set, which may be subject to future alterations. Lastly, we found that it may be relevant to present a set of improvement measures, either through the definition of new standards, new assessment methodologies, or even through training assessors and assesses on the subject.

O objectivo central deste trabalho é testar e caracterizar uma matriz de 4x4 de fotomultiplicadores, adquirida comercialmente, com recurso a um Banco de Testes de fotomultiplicadores desenvolvido e utilizado no projecto TileCal/ATLAS/CERN. Para a realização dos testes foi necessário proceder-se a diversas alterações Mecânicas, de Software e Electrónicas no Banco de Testes mencionado, bem como ao estudo do seu funcionamento. Os testes realizados incluem a determinação da Tensão de Funcionamento, Linearidade, Uniformidade, Ganho, Corrente Escura e Perfil da resposta do maPMT a impulsos luminosos. À excepção do teste da Corrente Escura, em que não há iluminação do PMT, todos os outros se realizam em condições de iluminação dos fotomultiplicadores em Modo Pulsado, com um LED azul. O objectivo do trabalho foi atingido, revelando bons resultados, sendo que o Banco de Testes de fotomultiplicadores se encontra completamente adaptado para ac aracterização da segunda matriz 4x4 de fotomultiplicadores costituintes do sistema MiniPET.

Its principal purpose will be illustrate the operation principles of a commercial PET and, therefore, contribute, in a didactic mean, to the formation of college students and professionals of nuclear imaging area. The central objective of this work is test and characterize one commercially adquired matrix of fotomultipliers, with resource to a Fotomultipliers Test Bench, developed and used in the TileCal/ATLAS/CERN project. It was necessary to proceed to several mechanical, software and electronics changes in the Test Bench, so that the execution of the tests could be made. It was also need to perform a complete study its operation. The fotomultiplier’s tests include the Nominal Voltage determination, Linearity, Uniformity, Gain, Dark Current, and maPMT profile response due to luminous pulses. With the exception of the Dark Current test, which there is no illumination of the PMT, all the tests have been made in conditions of Pulse Mode in the illumination of the dispositive, achieved by a blue LED. The purpose of the work was reached revealing good results, and the Fotomultipliers Test Bench is now completely adapted to the characterization of the second fotomultipliers matrix that constitute the MiniPET system.

Most multicellular organisms use steroids as signalling molecules for physiological and developmental regulation. Two different modes of steroid action have been described in animal systems: The well-known gene regulation response mediated by nuclear receptors (genomic action), and the rapid non-genomic responses mediated by proposed membrane-bound receptors (nongenomic action). Plants also use steroid-like compounds as signalling molecules, such as gibberellin (GA), abscisic acid (ABA) and brassinosteroids (BR). Arabidopsis genome does not seem to encode members of the animal nuclear receptor superfamily. However, we found four MAPR (Membrane Associated Progesterone Receptor component 1) homologs, AtMAPR2, AtMAPR3, AtMAPR4 and AtMAPR5 in Arabidopsis. Three MAPR homologs, AtMAPR2, AtMAPR3, and AtMAPR5 have been cloned and heterologously expressed in E. coli. One recombinant protein, AtMAPR2, was used to raise specific antibody and following functional analysis. We have obtained polyclonal and monoclonal antibody against AtMAPR2. Immunoprecipitation with specific polyclonal anti-AtMAPR2 antibody revealed the presence of AtMAPR2 in Arabidopsis. Microarray gene expression analysis showed that auxin, ABA, and stresses might alter the expression of AtMAPR2 gene. Auxin, ABA, cytokinin, and stresses could influence the expression of AtMAPR5 gene. In addition, AtMAPR5 T-DNA insertion mutant was shown to have the phenotype of dwarf, dark green leaves, longer petiole, upper stem tufted growth in the center of rosette leaves and abnormal shoot growth. Such phenotype may imply the involvement of auxin, ABA, GA regulation. We speculate that AtMAPRs might involve in the signalling of auxin, ABA, GA and cytokinin.

The Cu2O was proposed as the hole transporting material in the perovskite solar cells, and in this interface will occur the separation of the carrier charge. Electronic structure calculations were carried out through quantum mechanics using the Quantum ESPRESSO package. We have found the bands alignment of Cu2O and CH3 NH3PbI3. The procedure consist in calculating the profile of the electrostatic potential in the crystal/vacuum interface using the slab model. Previously the surface models were designed.

Ramaphoko, Mapiti Piet. « The balance between the principle of pacta sunt servanda and section 22 of the Constitution in a restraint of trade agreement / Mapiti Piet Ramaphoko ». Thesis, 2014. http://hdl.handle.net/10394/11952.
Texte intégralRésumé :
The focus of this discussion is whether there is still the need to enforce the restraint of trade agreements in their pre-Constitutional form. The dawn of the constitutional era has necessitated a re-examination of common law with a view to establishing whether the balance created by the latter (regarding this field) still exists.
The Bill of Rights has obviously raised some doubts regarding the equilibrium desired between employer and employee interests. Section 22 of the Constitution is to the effect that everyone must be free to secure employment (as a fundamental right), whereas the common law restraint of trade agreements impose some bars to the operation of the said right.
It is common course that the Constitution is more superior to common law, what remains a debateable issue is whether there are any reasonable limits that must be considered to justify the disregard of the Constitution. Serious arguments around the direct and indirect application of the Bill of Rights still persist and failure to resolve them would have the effect of excluding or weakening the application of the Bill to disputes arising in this field.
In common law the enforcement of restraint agreements is sine qua non for the greater good of protecting the sanctity of contracts. Contractual obligations must be fulfilled unless it would be unreasonable to enforce same.
The question of the onus to prove unreasonableness, which lies with the employee, turns to place an onerous burden on the employee. This coupled with the employee’s weaker bargaining power raises doubts as to whether the employee is in a better position to conclude a restraint of trade agreement. Common law does not consider or accommodate this concern in that its main object is the fulfilment of the agreement.
It is believed that the Constitution has ushered in a new approach which focuses mainly on the fairness of the agreement itself. The enforcement of the agreement must pass the constitutional muster built in section 22 in order to ensure that there is equilibrium between the employer (the restrainor) and employee (the restrainee) interests.
In the end this discussion explores whether it is justifiable to subject the Right to work (as provided by the Constitution) to the common law restraint which is opposed to the constitutional right. The circumstances under which the exclusion of section 22 is condonable are interrogated within the framework of conflicting case law.LLM (Labour Law), North-West University, Potchefstroom Campus, 2014

Texte intégralRésumé :
Perovskite solar cells are the emerging thin-film photovoltaics that has been most studied in the last decade, reaching record power conversion efficiencies close to those exhibited by silicon solar cells, which means a considerable breakthrough in photovoltaic technology. However, it has been found that in methylammonium lead halide perovskite devices, MAPbX₃, either the electron transport material or hole transport material, affects the perovskite material’s stability, compromising the perovskite device performance. Therefore, other alternatives should be considered to avoid the perovskite layer’s degradation, namely, the electron transport material employed in the perovskite solar cells.
This PhD project aimed to develop nanostructures alternatives to the standard titanium dioxide (TiO₂) through ZnO-based nanostructures, using a low-cost and versatile technique such as pulsed electrodeposition, and applying them as the electron transport layer within perovskite solar cells.
Well-aligned arrays of ZnO nanorods were produced by pulsed potentiostatic electrodeposition in aqueous media, under mild reaction conditions. Several modified substrates were evaluated for the growth of nanorods to optimise the nanorod diameter and vertical orientation. Using a TiO₂ intermediate layer as a template for the ZnO nanorods growth successfully allowed a decrease of the nanorod diameter, increased their spatial density, and increased the ZnO films’ chemical stability with time and under illumination. Also, it was verified that the pulsed electrodeposition conditions at which the nanorods grow, namely the pulse operational parameters, had a very appreciable impact on its optoelectronic properties.
Several ZnO thin films prepared using different deposition media were studied to assess the influence of ZnO nature on the thermal stability of the MAPbI₃ perovskite. Some chemical groups attached to the ZnO surface affected the crystallization of the perovskite layer and accelerated its thermal degradation at the ZnO/perovskite interface.
The ZnO@TiO₂ core-shell nanostructures were considered to prevent the perovskite instability issues when in intimate contact with ZnO. Despite the slight improvement in device performance using ZnO@TiO₂ core-shell nanorods, compared to ZnO nanorods, the morphological reproducibility of a TiO₂ shell that completely covers the ZnO surface is crucial to obtain higher photovoltaic performances.
