The world we live on is becoming more and more digital, our homes are growing in intelligence. Standards like DLNA and UPnP AV propose to exchange our digital media (photos, audio, video) in an automatic way. The UPnP forum is a industrial initiative created to allow easy connectivity and robustness between independent devices from di erent fabricators. The objective of this forum is to develop templates to discriminate the protocols and XML schemes involved in the process of interoperability in a scalable network. The DLNA alliance was created in July 2003 by the name Digital Home Working Group (DHWG), later changed to Digital Living Network Alliance (DLNA) in June 2004. The DLNA alliance is commanded by 23 companies (Access, Awox, Broadcom, Cisco, Comcast, HP, Huawei, IBM, Intel, Kenwood, LG Electronics, Macrovision, Microsoft, Motorola, Nokia, NXP Semiconductors, Panasonic, Philips, Pioneer, Samsung, Sharp, Sony e Toshiba) and have more then 245 members. Today consumers are acquiring, viewing and managing a big amount of digital information (images, audio, video) in their PCs, electronics devices and mobile devices. They want to access easily from any device in any part of the home to their information present in other devices. This idea is possible through a creation of a network with DLNA certi cated devices. A DLNA network o ers automatic inter-connectivity between devices to the consumers. It is an opportunity to innovate an di erentiate the products of their fabricators. From the operator point of view, increases the diagnose capability and remote management of the client network.

Sharing locally stored media files like music, videos and pictures has not been user-friendly for a long time now. Nowadays people, when they know where the media is stored, have to use the complicated network shares or external storage solutions like USB sticks, hard drives or even CD/DVDs to share media across different users. When the users do not know where the media is stored, they have to use Internet-based peer- to-peer applications like LimeWire, KaZaa or the Gnutella-network, which requires searching and downloading the media first, before being able to actually make use of it. But what if you do not have an Internet connection, do not want to mess around with external storage solutions nor want to wait while downloading or copying from a (network) device, but still want to make use of the media stored on another computer system? Indeed, nowadays there is not any easy solution that provides a very user-friendly, fast and responsive, flexible and stable solution for this. This problem brought us to our research question: “Is there a very easy solution for sharing or watching media throughout the local network?” After some research we stumbled upon some state-of-the-art technologies, which came very close to what we wanted to achieve, however, still having quite some drawbacks, not suitable as a solution for the problem mentioned above. We decided to innovate and tried to find a solution without any drawbacks while still being very user-friendly. We achieved quite good research results showing that: • Using a client-only network was the most efficient and flexible way to provide a stable network structure; • Java was the best programming language to provide a cross-platform application; • For compatibility with the media sharing itself an object-oriented based indexing storage structure, like db4o, yielded the best flexibility and speed in comparison with SQL or other technologies; • The streaming of the media could be achieved best by making use of Java VLC libraries. The user-friendliness of the demo application that we created was also very good, only a few clicks are sufficient to share your media across the network, no need to bother about user rights and so on. We can conclude that our research can be the base of a very successful innovative media sharing system and strongly believe, with some more adjustments in the future, that it has potential to become a very popular application along the media sharing industry.

Thesis (MScEng)--Stellenbosch University, 2011.ENGLISH ABSTRACT: This thesis addresses the complications that are encountered when characterising the performance of differential microwave LNAs. The predominant sources of noise in electronic circuits are introduced and equivalent two-port noise models for active devices are derived. Correlation between noise generators are defined by means of the noise correlation matrix and existing network theory is adapted to include noise analysis of twoport and multi-port networks. Mixed-mode scattering parameters are introduced in order to define the signal performance of differential and common-mode propagation in multi-port networks and, by applying the same theory, the mixed-mode correlation matrix for a three-port dLNA is derived. Furthermore, an expression is derived for de-embedding the differential noise figure of a three-port dLNA using two single ended measurements. Two dLNA designs, both incorporating wideband 180°-Hybrid ring couplers, are discussed and the differential signal and noise performance of the dLNAs are compared to that of their constituent single ended LNAs.

Full textAbstract:
Doctor of Philosophy(PhD)Menggwa Dla is a Papuan language spoken in Sandaun Province of Papua New Guinea and Kabupaten Jayapura of Papua Province, Indonesia. Menggwa Dla is a dialect of the Dla language; together with its sister language Anggor (e.g. Litteral 1980), the two languages form the Senagi language family, one of the small Papuan language families found in North-Central New Guinea. The main text of this thesis is divided into seven chapters. Chapter 1 introduces the linguistic, cultural and political landscapes of the Indonesia-Papua New Guinea border area where the Dla territory is located. Chapter 2 introduces the phonology of Menggwa Dla; described in this chapter are the phonemes, allophonic variations, phonotactics, morpho-phonological processes, stress assignment and intonation of the language. The inventory of phonemes in Menggwa is average for a Papuan language (15 consonants and 5 vowels). The vast majority of syllables come in the shape of V, CV or C1C2V where C2 can be /n/ /r/ /l/ /j/ or /w/. In C1C2V syllables, the sonority rises from C1 to V (§2.2.2). Nevertheless, there are a few words with word-medial consonant sequences like ft /ɸt/, lk /lk/, lf /lɸ/ or lk /lk/ where the sonority drops from the first to the second consonant; the first consonant in these sequences is analysed as the coda of the previous syllable (§2.2.3). Chapter 3 is an overview of the word classes in Menggwa Dla; the morphological, syntactic and semantic properties of the three major word classes (nouns, adjectives and verbs) and the minor word classes are compared in this chapter. Chapter 4 describes the properties of nouns and noun phrases; the person-number-gender categories, noun-phrasal syntax, nominal clitics and personal pronouns are outlined in this chapter. Menggwa Dla has a rich array of case, topic and focus markers which comes in the form of clitics (§4.5). Subject pronouns (‘citation pronouns’) only mark person (i.e. one for each of the three persons), whereas object and genitive pronouns mark person (including inclusive/exclusive first person), number, and sometimes also gender features (§4.6). Chapter 5 introduces various morphological and syntactic issues which are common to both independent and dependent clauses: verb stems, verb classes, cross-referencing, intraclausal syntax, syntactic transitivity and semantic valence. Cross-referencing in Menggwa Dla is complex: there are seven paradigms of subject cross-reference suffixes and four paradigms of object cross-references. Based on their cross-referencing patterns, verbs are classified into one of five verb classes (§5.2). There is often a mismatch between the number of cross-reference suffixes, the semantic valence, and the syntactic transitivity within a clause. There are verbs where the subject cross-reference suffix, or the object suffix, or both the subject and object suffixes are semantically empty (‘dummy cross-reference suffixes’; §5.3.2). Chapter 6 outlines the morphology of independent verbs and copulas. Verbal morphology differs greatly between the three statuses of realis, semi-realis and irrealis; a section is devoted to the morphology for each of the three statuses. Chapter 7 introduces the dependent clauses and verbal noun phrases. Different types of dependent verbs are deverbalised to various degrees: subordinate verbs are the least deverbalised, chain verbs are more deverbalised (but they mark switch-reference (SR), and sometimes also interclausal temporal relations), and non-finite chain verbs even more deverbalised. Further deverbalised than the non-finite chain verbs are the verbal nouns; verbal noun phrases in Menggwa Dla functions somewhat like complement clauses in English. In younger speakers speech, the function of the chain clause SR system has diverted from the canonical SR system used by older speakers (§7.2.2). For younger speakers, coreferential chain verb forms and disjoint-reference chain verb forms only have their coreferential and disjoint-referential meaning — respectively — when the person-number-gender features of the two subject cross-reference suffixes cannot resolve the referentiality of the two subjects. Otherwise, the coreferential chain verb forms have become the unmarked SR-neutral chain verb forms. At the end of this thesis are appendix 1, which contains four Menggwa Dla example texts, and appendix 2, which contains tables of cross-reference suffixes, pronouns, copulas and irregular verbs.

The thesis is devoted to determining the parameters of the bucket to increase productivity of dredgers while mining deep-water organic-mineral sediments. It was achieved by increasing the fill factor through determining the rational geometrical parameters of the bucket. Analytical dependencies of the rational height and length of the bucket on the cutting parameters and physical-and-mechanical properties of the excavated sediments were determined. Expressions for defining forces while digging plasticity water-saturated soils were developed. Experimental investigations of the process of digging deep-water organic-mineral sediments in laboratory conditions and in the real conditions of operating single-bucket dredger in the Black Sea at the depth of 1885 m were carried out. The technique for calculation of the bucket\'s parameters was developed.

Full textAbstract:
Les bactéries lactiques présentent une parfaite innocuité hygiénique et sont de bons candidats pour le développement de nouvelles utilisations. Dans le développement de vaccins vivants, la sécrétion peut être préférable à une production cytoplasmique. Nous avons étudié la sécrétion de protéines hétérologues chez Lactococcus lactis en employant la nucléase de S. Aureus comme protéine sécrétée modèle. Nous avons agi sur les facteurs intrinsèques de Nuc par l'utilisation d'un peptide signal de L. Lactis pour diriger la sécrétion et sur l'équilibre des charges de la partie N-terminale pour augmenter l'efficacité de sécrétion. Pour mieux comprendre la sécrétion chez L. Lactis, nous avons identifié des facteurs d'hôtes qui sont impliqués directement ou non dans la sécrétion. Par mutagenèse insertionnelle aléatoire nous avons identifié, puis analysé, deux nouveaux facteurs d'hôtes, dltA et ybdD. L'inactivation de dltA modifie les charges à la surface de la cellule et entraîne la rétention de Nuc sécrétée. L'inactivation de ybdD dérégule l'expression de gènes pouvant contrôler la sécrétion. Tous les composants de la machinerie Sec sont présents, à l'exception de SecDF. Chez B. Subtilis, SecDF maintient une forte capacité de sécrétion. La complémentation du sécrétome de L. Lactis par SecDF de B. Subtilis augmente la sécrétion. Afin d'évaluer la possible utilisation de L. Lactis comme vecteur de protéines immunogènes pour déclencher une réponse immune chez la souris, nous avons construit des souches de L. Lactis produisant une fusion entre Nuc et un épitope immunogène de la beta-lactoglobuline (Blg). La Blg est l'allergène majeur chez les nourrissons allergiques au lait de vache et constitue un bon modèle d'allergie alimentaire. L'administration orle des souches de L. Lactis produisant l'epitope declenche chez la souris une réponse immunitaire mucosale, non allergique, spécifique de la BlgLactic acid bacteria (LAB) are Gram-positive bacteria generally considered as safe (GRAS) and they are therefore excellent potential candidates for the development of new uses such as live vectors for the delivery of immunogenic proteins. To this purpose, secretion of heterologous proteins could be more advantageous than cytoplasmic production. We studied the heterologous protein secretion in Lactococcus lactis with the staphylococcal nuclease (Nuc) as secretory model protein. By the use of a lactococcal signal peptide to drive Nuc secretion and a synthetic propeptide to maintain an optimal charge balance at the N-terminal end of Nuc, the Nuc secretion efficiency was strongly improved. To better understand secretion, we identified by random insertional mutagenesis two new host factors indirectly involved in secretion. Inactivation of dltA unbalances charges present at the cell surface and leads to Nuc entrapment into the cell wall. Inactivation of ybdD up-regulates expression of several genes of which products might control secretion in L. Lactis. The analysis of the so-called secretome in L. Lactis reveals that all components of the Sec machinery are present except SecDF. In B. Subtilis, SecDF is necessary in late secretion stages. Introduction of SecDF from B. Subtilis into the L. Lactis secretome improves secretion of several heterologous proteins. To evaluate the potential use of L. Lactis as vector of an allergen to trigger an immune response in mice, we developed L. Lactis strains secreting a fusion between Nuc and an immunogenic epitope of β-lactoglobulin (Blg). Blg is the major cow milk allergen in childhood and a good model for study of food allergy. Oral administration of L. Lactis secreting this fusion protein triggers a specific mucosal immune and non allergic type response in mice, against both the epitope and the entire Blg

The aim of this work is to explore, using computational techniques that simulate the motion and subsequent aggregation of particles in aerosol and colloidal systems, many common but not well studied systems that form fractal clusters. Primarily the focus is on cluster shape and growth kinetics. The structure of clusters made under diffusion limited cluster-cluster aggregation (DLCA) is looked at. More specifically, the shape anisotropy is found to have an inverse relationship on the scaling prefactor "k"_"0" and have no effect on the fractal dimension "D"_"f". An analytical model that predicts the shape and fractal dimension of diffusion limited cluster-cluster aggregates is tested and successfully predicts cluster shape and dimensionality. Growth kinetics of cluster-cluster aggregation in the free molecular regime where the system starts with ballistic motion and then transitions to diffusive motion as the aggregates grow in size is studied. It is shown that the kinetic exponent will crossover from the ballistic to the diffusional values and the onset of this crossover is predicted by when the nearest neighbor Knudsen number reaches unity. Simulations were carried out for a system in which molten particles coalesce into spheres, then cool till coalescing stops and finally the polydispersed monomers stick at point contacts to form fractal clusters. The kinetic exponent and overall cluster structure for these aggregates was found to be in agreement with DLCA that started with monodispersed monomers. Colloidal aggregation in the presence of shear was studied in detail. Study of a colloidal system characterized a by short-range attractive potential showed that weak shear enhanced the aggregation process. Strong shear led to fragmentation and subsequent nucleation as cluster growth rebounded after an induction time.

Poezja dla dzieci jest to dziedzina twórczości literackiej wyróżniana ze względu na stosunkowo wyrazistą kategorię adresata. Za poezję dla dzieci uznaje się jedynie utwory intencjonalnie kierowane do dzieci.
W myśl klasyfikacji historyka literatury J. Cieślikowskiego najbardziej uchwytne są te formy poezji dla dzieci, które mają odpowiedniki w folklorze: kołysanki, wyliczanki, rymowanki itp.
Rozwój polskiej poezji dla dzieci charakteryzuje wielość tendencji, ujawniających się w różnych modelach wierszy: od dydaktycznego S. Jachowicza, przez pieśniowy M. Konopnickiej, ludowy J. Porazińskiej, „dziecięcy” K. Iłłakowiczówny, lingwistyczny J. Tuwima i J. Brzechwy, medytacyjny J. Kulmowej, refleksyjny J. Ratajczaka, do kreacyjnego A. Kamieńskiej, W. Chotomskiej i D. Wawiłow. Punktem dojścia jest liryka dziecięcego punktu widzenia. W utworach młodszej generacji poetów wiersze dla dzieci tracą często regularny rytm i rym, na plan pierwszy wysuwa się obraz poetycki, ton refleksyjny oraz zabawa słowami i fabułami utworów.
Bajka – to jeden z najczęściej uprawianych gatunków literatury dydaktycznej. Ze względu na walory dydaktyczne (jasno sprecyzowany morał) oraz przystępność formy (niewielka objętość) utwory należące do tego gatunku występują od początku rozwoju literatury dla dzieci po współczesność. W obrębie bajki wyróżnia się zwykle dwa podgatunki: bajka magiczna, czyli baśń i bajka zwierzęca. Za twórcę tej ostatniej uważa się bajkopisarza greckiego Ezopa, pochodzącego z Azji...

Poetry for children is the sphere of literature which is singled out for its clear audience category. The poetry is intended for children. Esthetical function usually prevailing in literature is modified in poetry for children to become didactical. It is important to maintain a relation between the young listener and the narrator. Paradramatical forms, anecdotes, epical forms with attractive narration are met in poetry for children. According to J.Cieslikowski, literature historian, the most acceptable are the forms of poetry which have equivalents in folk: lullabies, counting-out rhymes and e. c. Poetry for children developed from the simplest forms used to entertain or to lull kids, through counting-out rhymes to more complicated: songs inspired by folk, then fables, and finally, rhymed mini-tales intended for kids.

The increased emissions monitoring requirements of industrial gas turbines have created a demand for less expensive emissions monitoring systems. Typically, emissions monitoring is performed with a Continuous Emissions Monitoring System (CEMS), which monitors emissions by direct sampling of the exhaust gas. An alternative to a CEMS is a system which predicts emissions using easily measured operating parameters. This system is referred to as a Parametric Emissions Monitoring System (PEMS). A review of the literature indicates there is no globally applicable PEMS. Because of this, a PEMS that is applicable to a variety of gas turbine manufacturers and models is desired. The research presented herein includes a literature review of NOx reduction techniques, NOx production mechanisms, current PEMS research, and combustor modeling. Based on this preliminary research, a combustor model based on first-engineering principles was developed to describe the NOx formation process and relate NOx emissions to combustion turbine operating parameters. A review of available literature indicates that lean-premixed combustion is the most widely-used NOx reduction design strategy, so the model is based on this type of combustion system. A review of the NOx formation processes revealed four well-recognized NOx formation mechanisms: the Zeldovich, prompt, nitrous oxide, and fuel-bound nitrogen mechanisms. In lean-premixed combustion, the Zeldovich and nitrous oxide mechanisms dominate the NOx formation. This research focuses on combustion modeling including the Zeldovich mechanism for NOx formation. The combustor model is based on the Siemens SGT-200 combustion turbine and consists of a series of well-stirred reactors. Results show that the calculated NOx is on the same order of magnitude, but less than the NOx measured in field tests. These results are expected because the NOx calculation was based only on the Zeldovich mechanism, and the literature shows that significant NOx is formed through the nitrous oxide mechanism. The model also shows appropriate trends of NOx with respect to various operating parameters including equivalence ratio, ambient temperature, humidity, and atmospheric pressure. Model refinements are suggested with the ultimate goal being integration of the model into a PEMS.

Absorption profiles are found in the observed spectra from quasars, and the most prominent of these are the Damped Lyman-alpha Absorbers (DLAs). They are caused by large collections of neutral hydrogen (HI) gas, which are thought to be housed in galaxies that lie along the line-of-sight to quasars. HI gas associated with DLAs contains most of the HI gas in the Universe during 2 < z < 5, and hence details about DLAs are important for understanding the history of star formation, as well as the formation and evolution of galaxies. Wyithe (2008) proposed a method of determining the characteristic mass of dark matter haloes that host DLAs. This involves generating an analytic power spectrum of the fluctuations in 21cm brightness temperature caused by the HI gas in the Universe. Calculating this analytic 21cm power spectrum requires a formalism for the HI mass weighted clustering bias of DLAs on both large and small scales. We include this DLA clustering bias by firstly generating an analytic galaxy power spectrum using the halo model of Peacock & Smith (2000), as well as including the occupation of haloes by galaxies -- using the Halo Occupation Distribution (HOD) weighting of Peacock (2003). This weighting is then adapted to account for the occupation of haloes by HI gas.We then fit the analytic 21cm power spectrum generated using this formalism to a simulated 21cm power spectrum, with the characteristic mass of DLA host haloes being used as a fitting parameter. The DLA host halo mass is in turn dependent upon two parameters in our model: the minimum mass of haloes M_{min} included in our formalism, and the HI weighting index alpha_{HI}. The neutral hydrogen fraction is another parameter, which we can choose to be the same as that from our simulation volume. If we also choose a value for alpha_{HI} that is motivated by analysis of the dark matter and HI gas content of the haloes in the simulation, then we are able to fit the 21cm power spectrum at both large and small scales, with an M_{min} that is the same or similar to the lowest mass in the simulation's halo catalogue. This in turn gives a similar value for the DLA host halo mass that is known to be the case in the simulation. This demonstrates the viability of the Wyithe (2008) method for determining the DLA host halo mass using observations of 21cm fluctuations. However, degeneracies in the free parameters of our analytic formalism would hinder an accurate determination of the DLA host halo mass from actual future observations. This is due to the fact that the real space, spherically averaged 21cm power spectrum is used throughout this thesis. However, extending our analytic formalism to the redshift space, angular-dependent 21cm power spectrum should be capable of breaking the degeneracy between DLA host halo mass and neutral hydrogen fraction.

Approved for public release; distribution is unlimitedThe Department of Defense (DoD) has consolidated the physical distribution functions for wholesale consumable material under the Defense Logistics Agency (DLA). As a consequence, service customers are worried that many repair parts that used to be geographically co-located would be moved to distant DLA supply depots. One DLA proposal, to combat these fears, is to stock material in a given geographic region if the demand in that region is above a certain percentage of system-wide demand. This study evaluates that proposal by looking at the demand of electronic items over a one-year period in the San Diego and Norfolk geographic regions. In particular, it compares transportation costs between maintaining the current DLA stockage policy and stocking all items at Defense Depot San Diego. The study found that second destination transportation cost savings ranged from 55% for items that experienced 90% to 99% of their demand in the San Diego area, to 2.8% for items with 40% to 49% of their demand in the San Diego area

Plusieurs auteurs ont identifié des problèmes au niveau du développement sportif de jeunes s’étant spécialisés dans une discipline sportive à un âge précoce. Ceux-ci sont : (a) l’augmentation des blessures, (b) la perte de plaisir de la pratique, (c) le manque de diversité dans les expériences sociales vécues, (d) l’abandon sportif, (e) le « burnout » [épuisement sportif] et (f) la pression des entraîneurs et des pairs (Fraser-Thomas, Côté et Deakin 2005; Hecimovich, 2004; Law, Côté et Ericsson, 2007; Wall et Côté, 2007).
En 2005, un document a vu le jour afin de contrer diverses problématiques sportives, dont la spécialisation sportive. Ce document se nomme « Au Canada, le sport c’est pour la vie » (Balyi, Cardinal, Higgs, Norris, et Way, 2005) ou plus communément appelé le modèle de développement à long terme de l’athlète (DLTA). Écrit à l’intention des entraîneurs, des athlètes, des administrateurs et des parents, il s’agit essentiellement d’un modèle d’entraînement qui vise à établir les lignes directrices de la planification de l’entraînement, de la compétition et de la récupération (Robertson et Way, 2005). Le message qu’il véhicule est d’encourager un développement des habiletés motrices et sportives à l’aide d’un entraînement de type multisports favorisant un développement à long terme de l’athlète (DLTA), tout en évitant la spécialisation sportive hâtive. Ce programme multisports s’appuie également sur des études conduites sur la pratique sportive chez les jeunes, notamment sur des travaux de Fraser-Thomas, Côté et Deakin (2005) et ceux de Côté, Baker et Abernethy (2003), qui portent sur une approche multisports afin de contrer l’abandon sportif, causé par la spécialisation hâtive.
Le présent projet de recherche porte sur la description de l’élaboration et la mise en œuvre d’un programme multisports en milieu scolaire s’inspirant des recommandations du modèle DLTA (Balyi et coll., 2005). En contexte québécois, ce programme devait aussi respecter les exigences du ministère de l’Éducation, du Loisir et du Sport avec le programme de formation de l’école québécoise en milieu secondaire (Ministère de l’Éducation, du Loisir et du Sport, 2003). Le programme a été développé et mis en place par un éducateur physique sous la supervision de spécialistes (kinésiologues, nutritionnistes et entraîneurs).
L’objectif principal de ce projet de recherche est de décrire les étapes d’élaboration et de mise en œuvre d’un programme multisports-études implanté dans une école secondaire du Québec à partir des perceptions des principaux acteurs impliqués dans le programme (gestionnaires, intervenants et parents), afin d’en tirer des recommandations qui pourraient guider des intervenants sportifs québécois intéressés par une telle démarche. Ainsi, ce projet propose un éclairage sur les différentes étapes menant à l’élaboration et à la mise en œuvre de programmes multisports-études en milieu scolaire. Plus précisément, la recherche a tenté de déterminer : (a) les visées du programme, (b) les critères de sélection des élèves, (c) la planification des activités, (d) les rôles et tâches de chacun des acteurs impliqués au programme et (e) les ressources matérielles nécessaires à la mise en œuvre de ce programme. L’étude vise finalement à (f) identifier les principales difficultés rencontrées lors de la mise en œuvre du programme.
Afin d’atteindre les objectifs de l’étude, sept gestionnaires, six intervenants ainsi que six parents ont été sollicités. La principale méthode de collecte de données utilisée a été l’entretien de type semi-dirigé. Des grilles d’entrevue ont été développées dans le but d’adopter une démarche constante lors de la collecte de données et ainsi permettre au chercheur d’amasser le maximum d’information chez les participants. De plus, des documents écrits (procès-verbaux de rencontres, documents envoyés aux parents, dépliants du programme, politique institutionnelle) permettent de mieux comprendre comment s’est déroulée la démarche.
Les résultats révèlent quelques difficultés lors de l’élaboration du programme : (a) un manque de constance et de cohérence dans l’élaboration des objectifs et visées. De plus, (b) l’acceptation du nouveau programme par le milieu semble avoir été difficile à tous les niveaux. Il semble que l’élaboration d’un nouveau programme de la sorte soulève plusieurs inquiétudes chez les acteurs au plan de : (c) la disponibilité des plateaux sportifs en nombre insuffisant, (d) la création d’horaires scolaires plutôt complexes, (e) le conflit avec les programmes sportifs déjà en place et (f) le manque d’informations claires sur les lignes directrices du DLTA. De plus, (g) l’écriture du programme sans cadre de référence a causé bien des soucis à l’intervenant principal. Ensuite, (h) les canaux de communication entre les divers intervenants et gestionnaires semblent avoir nui à l’élaboration efficace du programme. En effet, (i) plusieurs acteurs ont fait ressortir que les rôles et les tâches n’avaient pas été clairement établis au départ. De plus, (j) les mesures académiques particulières au profit de l’élève semblent avoir posé problème également au niveau de leur efficacité. Enfin, un dernier élément est ressorti comme problématique par plusieurs intervenants soit : (k) la nature des critères de sélection, qui, ne semble pas avoir fait l’unanimité quant à son contenu et ses visées. Les parents ont quant à eux fait ressortir qu’ils étaient insatisfaits de (l) l’offre de service au niveau académique.
Pour ce qui est de la mise en œuvre du programme, l’ensemble des intervenants (éducateurs physiques, kinésiologue, conseiller pédagogique) et des gestionnaires (agent de développement sport, directeur de la commission scolaire, directrice des finances à la commission scolaire, directeur des ressources éducatives à la commission scolaire, directeur et directeur adjoint de l’école secondaire) s’accordent à en confier la direction, soit à un professionnel, soit à un éducateur physique. De ce fait, le soutien à l’intervenant principal ressort comme étant une nécessité tant au niveau sportif qu’académique, afin de l’épauler dans la mise en œuvre du programme. À ce niveau, (m) les mesures de soutien à l’éducateur physique sont apparues comme étant insuffisantes ou inadéquates par certains intervenants et gestionnaires. Ensuite, (n) les infrastructures nécessaires au bon déroulement du programme ont représenté une grande difficulté lors de la mise en œuvre du programme.
Suite à l’analyse des résultats, les différentes recommandations qui émanent du projet afin d’élaborer et mettre en œuvre un programme multisports-études sont : (a) utiliser un modèle d’élaboration de programme (Gallahue et Cleland-Donnelly, 2003), (b) identifier collectivement une philosophie, une mission et une raison d’être pour le programme, (c) construire un organigramme des rôles et des tâches de chacun des acteurs, (d) identifier le cadre conceptuel du programme et les objectifs généraux, (e) identifier les objectifs spécifiques du programme, (f) élaborer un modèle d’évaluation de programme, (g) planifier le soutien à l’intervenant principal et (h) développer des canaux de communication efficaces entre les intervenants, les gestionnaires et les parents.

Dissertação de Mestrado Integrado em Medicina VeterináriaOs bovinos são animais homeotérmicos e como tal têm uma Zona de Conforto Térmico. Fora desta sofrem stress térmico para manter a sua temperatura corporal. Este é observado em consequência de eventos climáticos extremos e tem efeitos negativos a nível produtivo, reprodutivo, metabólico e, no pior dos cenários, culmina na morte dos animais. O conhecimento da zona de conforto térmico dos bovinos e efeitos da temperatura são de interesse primário, pois permitem aplicar medidas preventivas adaptadas ao ambiente local e ajustar as condições de produção dos bovinos. Além disso, é importante perceber de que forma é que o stress térmico influencia a taxa de mortalidade e em que proporção. Neste estudo fez-se uma caracterização da variação da taxa de mortalidade ao longo do ano para as 7 regiões em que o país foi dividido, analisando-se dados relativos a um período de 4 anos (2015-08-15 a 2019-08-15). Avaliou-se e quantificou-se também a relação do THI (Índice de Temperatura-Humidade) com o Risco Relativo, ou seja, a relação exposição-resposta tendo em conta os desfasamentos temporais, através de Modelos Não Lineares com Desfasamento Distribuído (DLNM). Para tal consideram-se todas as explorações bovinas presentes em Portugal continental, que no período em estudo, tinham informação relativa à sua localização e que apresentavam continuidade de registos no Sistema Integrado de Recolha de Cadáveres de Animais (SIRCA), assim como os bovinos nelas presentes. Os registos das mortes foram obtidos da base de dados do SIRCA e os dados climáticos das estações meteorológicas localizadas em Portugal continental. Verificou-se que a taxa de mortalidade apresenta sazonalidade ao longo do ano, sendo que a faixa etária dos animais entre 1 e 60 dias é a que apresenta valores mais elevados. Valores de THI a partir de 75 e abaixo de 45, têm efeitos imediatos e desfasados no tempo (até 25 dias), com risco de morrer de 1,2 a 3 vezes mais, respetivamente.
ABSTRACT - Cattle are homeothermal animals and as such they have a thermal comfort zone. Beyond this, they experience thermic stress to maintain their body temperature. Thermic stress is observed in association with extreme weather events. It has negative effects, by affecting production, reproduction, metabolism and, in worse case, it ends with death. The knowledge of cattle comfort zones and temperature effects are of primary interest, as they allow the application of preventive measures adapted to the local environment and adjust the production conditions of the cattle. Furthermore, it is important to understand in which way is thermic stress affecting mortality rate and in what proportion. Thus, in this study, we characterized the variation of mortality rate through the year, in 7 regions that the country was divided, by analysing data for a period of 4 years (2015-08-15 a 2019-08-15). We described and quantified the relationship between THI (temperature-humidity index) with relative risk, in other words, the exposure-response relationship, considering delayed effects, through distributed lag non-linear models (DLNM). For this purpose, all bovine holdings present in mainland Portugal during the study period are considered to have information regarding their location and which had continuity of records in the Integrated Animal Corps Collection System (SIRCA), and the cattle present in them. The death records were obtained from the SIRCA database and the climatic data from the weather stations. It was found that the mortality rate presents seasonality throughout the year, with the age group of animals between 1 and 60 days being the one with the highest values. THI values from 75 and below 45, have immediate and lagged effects (up to 25 days), with a risk of dying 1.2 to 3 times more, respectively.

Résumé : L’entrainement sportif est « un processus de perfectionnement de l’athlète dirigé selon des principes scientifiques et qui, par des influences planifiées et systématiques (charges) sur la capacité de performance, vise à mener le sportif vers des performances élevées et supérieures dans un sport ou une discipline sportive » (Harre, 1982). Un entrainement sportif approprié devrait commencer dès l’enfance. Ainsi, le jeune sportif pourrait progressivement et systématiquement développer son corps et son esprit afin d’atteindre l’excellence sportive (Bompa, 2000; Weineck, 1997).
Or plusieurs entraineurs, dans leur tentative de parvenir à des résultats de haut niveau rapidement, exposent les jeunes athlètes à une formation sportive très spécifique et rigoureuse, sans prendre le temps de développer convenablement les aptitudes physiques et motrices et les habiletés motrices fondamentales sous-jacentes aux habiletés sportives spécifiques (Bompa, 2000), d’où l’appellation « spécialisation hâtive ». Afin de contrer les conséquences néfastes de la spécialisation hâtive, de nouvelles approches d’entrainement ont été proposées. Une des façons d’y arriver consisterait notamment à pratiquer différents sports en bas âge (Fraser-Thomas, Côté et Deakin, 2008; Gould et Carson, 2004; Judge et Gilreath, 2009; LeBlanc et Dickson, 1997; Mostafavifar, Best et Myer, 2013), d’où l’appellation « diversification sportive ».
Plusieurs organisations sportives et professionnelles ont décidé de valoriser et de mettre en place des programmes basés sur la diversification sportive (Kaleth et Mikesky, 2010). C’est donc à la suite d’une prise de conscience des effets néfastes de la spécialisation hâtive que des professionnels de l’activité physique d’une école secondaire du Québec (éducateur physique, kinésiologue et agent de développement sportif) ont mis en place un programme multisports-études novateur au premier cycle du secondaire, inspiré des sciences du sport et des lignes directrices du modèle de développement à long terme de l’athlète (DLTA) (Balyi, Cardinal, Higgs, Norris et Way, 2005).
Le présent projet de recherche porte sur le développement des aptitudes physiques et motrices chez de jeunes sportifs inscrits à un programme de spécialisation sportive et de jeunes sportifs inscrits à un programme de diversification sportive à l’étape « S’entrainer à s’entrainer » (12 à 16 ans) du modèle de développement à long terme de l’athlète (Balyi et al., 2005). L’objectif principal de cette étude est de rendre compte de l’évolution des aptitudes physiques et motrices de jeunes élèves-athlètes inscrits, d’une part, à un programme sport-études soccer (spécialisation) et, d’autre part, à un programme multisports-études (diversification). Plus spécifiquement, cette étude tente de (a) dresser un portrait détaillé de l’évolution des aptitudes physiques et motrices des élèves-athlètes de chaque programme et de faire un parallèle avec la planification annuelle de chaque programme sportif et (b) de rendre compte des différences d’aptitudes physiques et motrices observées entre les deux programmes.
Le projet de recherche a été réalisé dans une école secondaire de la province de Québec. Au total, 53 élèves-athlètes de première secondaire ont été retenus pour le projet de recherche selon leur volonté de participer à l’étude, soit 23 élèves-athlètes de première secondaire inscrits au programme sport-études soccer et 30 élèves-athlètes de première secondaire inscrits au programme multisports-études. Les élèves-athlètes étaient tous âgés de 11 à 13 ans. Treize épreuves standardisées d’aptitudes physiques et motrices ont été administrées aux élèves-athlètes des deux programmes sportifs en début, en milieu et en fin d’année scolaire. Le traitement des données s’est effectué à l’aide de statistiques descriptives et d’une analyse de variance à mesures répétées.
Les résultats révèlent que (a) l’ensemble des aptitudes physiques et motrices des élèves-athlètes des deux programmes sportifs se sont améliorées au cours de l’année scolaire, (b) il est relativement facile de faire un parallèle entre l’évolution des aptitudes physiques et motrices des élèves-athlètes et la planification annuelle de chaque programme sportif, (c) les élèves-athlètes du programme multisports-études ont, en général, des performances semblables à celles des élèves-athlètes du programme sport-études soccer et (d) les élèves-athlètes du programme sport-études soccer ont, au cours de l’année scolaire, amélioré davantage leur endurance cardiorespiratoire, alors que ceux du programme multisports-études ont amélioré davantage (a) leur vitesse segmentaire des bras, (b) leur agilité à l’épreuve de course en cercle et (c) leur puissance musculaire des membres inférieurs, confirmant ainsi que les aptitudes physiques et motrices développées chez de jeunes athlètes qui se spécialisent tôt sont plutôt spécifiques au sport pratiqué (Balyi et al., 2005; Bompa, 1999; Cloes, Delfosse, Ledent et Piéron, 1994; Mattson et Richards, 2010), alors que celles développées à travers la diversification sportive sont davantage diversifiées (Coakley, 2010; Gould et Carson, 2004; White et Oatman, 2009).
Ces résultats peuvent s’expliquer par (a) la spécificité ou la diversité des tâches proposées durant les séances d’entrainement, (b) le temps consacré à chacune de ces tâches et (c) les exigences reliées à la pratique du soccer comparativement aux exigences reliées à la pratique de plusieurs disciplines sportives. Toutefois, les résultats obtenus restent complexes à interpréter en raison de différents biais : (a) la maturation physique, (b) le nombre d’heures d’entrainement effectué au cours de l’année scolaire précédente, (c) le nombre d’heures d’entrainement offert par les deux programmes sportifs à l’étude et (d) les activités physiques et sportives pratiquées à l’extérieur de l’école. De plus, cette étude ne permet pas d’évaluer la qualité des interventions et des exercices proposés lors des entrainements ni la motivation des élèves-athlètes à prendre part aux séances d’entrainement ou aux épreuves physiques et motrices.
Finalement, il serait intéressant de reprendre la présente étude auprès de disciplines sportives différentes et de mettre en évidence les contributions particulières de chaque discipline sportive sur le développement des aptitudes physiques et motrices de jeunes athlètes.Abstract : Sports training is an athletic development process based on scientific principles aimed at enabling athletes to achieve enhanced or superior performance in a sport through planned and systematic influences (training loads) on their performance ability (Harre, 1982). An appropriate sports training program should start at an early age, so young athletes can progressively and systematically develop their body and mind to achieve sporting excellence (Bompa, 2000; Weineck, 1997). Yet, as they try to rapidly achieve superior results, many coaches impose a very specific and rigorous training regime on young athletes without taking the time to properly develop the basic physical and motor abilities underlying the specific sports skills (Bompa, 2000) – hence the term “early sport specialization”. New approaches have been put forward to address the negative consequences of early sport specialization. One approach is to participate in several sports at an early age (FraserThomas, Côté and Deakin, 2008; Gould and Carson, 2004; Judge and Gilreath, 2009; LeBlanc and Dickson, 1997; Mostafavifar, Best and Myer, 2013) – hence the term “sport diversification”. Many professional and sports organizations have decided to promote and implement programs based on sport diversification (Kaleth and Mikesky, 2010). Aware of the adverse effects of early specialization, some Quebec high school physical education professionals (a physical educator, a kinesiologist and a sports agent) have implemented an innovative junior high school multisport program drawing on sport sciences and the Long-Term Athlete Development (LTAD) model guidelines (Balyi et al., 2005). This research project examines physical and motor abilities development among young athletes enrolled in a sport specialization program as well as young athletes enrolled in a sport diversification program who have reached the “Train to Train” stage of the LTAD model (12 to 16 years old) (Balyi et al., 2005). The main objective of this research project is to document the changes in the physical and motor abilities of young student-athletes enrolled, on one hand, in a sport studies program in soccer (specialization) and, on the other hand, in a multi-sport program (diversification). More specifically, this research attempts to (a) provide a comprehensive picture of the changes in physical and motor abilities of the studentathletes in each program, and hopes to draw a parallel with the annual planning of each sports program, and (b) identify any contrasts between the physical and motor abilities of the student-athletes in each program. 9 The results indicate that (a) the student-athletes in both sports programs improved all their physical and motor abilities during the school year; (b) it is relatively easy to draw a parallel between the development of the physical and motor abilities of the student-athletes and the annual planning of each sports program; (c) overall, the student-athletes enrolled in the multi-sport program demonstrated similar or better performance than the student-athletes enrolled in the sport studies program in soccer; and (d) during the school year, student-athletes enrolled in the sport studies program in soccer showed more improvement of their cardio-respiratory endurance, whereas the student-/athletes enrolled in the multi-sport program showed more improvement in (a) the segmental speed of their arms, (b) their agility during the circle run test and (c) the muscle power of their lower limbs, confirming that young athletes who specialize early, develop a set of physical and motor abilities that are rather sportspecific (Balyi et al., 2005; Bompa, 1999; Cloes, Delfosse, Ledent and Piéron, 1994; Mattson and Richards, 2010), whereas the skills developed through sport diversification are more varied (Coakley, 2010; Gould and Carson, 2004; White and Oatman, 2009). The research project was realized in a Quebec high school. In total, 53 secondary one student-athletes were selected for the research project based on their willingness to participate in the study, 23 student-athletes enrolled in sports study soccer program and 30 student athletes enrolled in the multi-sport study program. All the student-athletes were aged between 11 and 13 years old. Thirteen physical and motor skills standardized tests were conducted to all the student-athletes in both programs. The tests were administered at the beginning, in the middle and at the end of the school year. Data processing was performed by using descriptive statistics and ANOVA repeated mesures. These findings may be explained by (a) the level of specificity or of diversity of the exercises proposed during the training sessions, (b) the time spent on each exercise, and (c) the requirements of the game of soccer compared to the requirements of the participation in several sports. However, these findings remain difficult to interpret due to various factors: (a) physical maturity, (b) the number of hours of training during the previous school year, (c) the number of hours of training of both sports programs, and (d) the participation in physical activities and sports outside of school programs. Also, this research does not assess the quality of the interventions of the exercises proposed during the training sessions,nor the motivation of the student athletes taking part in the trainings sessions and during the physical and motor skills tests. Finally, it would be interesting to extend this research to various sports to demonstrate the specific contributions of each discipline to the development of the physical and motor abilities of young athletes.

Full textAbstract:
Cette thèse porte sur deux types de problèmes de mécanique statistique : il y est question de percolation sur les groupes et de modèles dirigés. Dans le premier cas,il s’agit de réaliser un groupe comme objet géométrique (via la notion de graphe de Cayley), puis de morceler ce dernier aléatoirement. L’étude de ce processus révèle des liens étroits entre les propriétés géométriques d’un groupe et le comportement de la percolation de Bernoulli sur celui-Ci. Dans le second cas, on s’intéresse à des modèles où haut et bas jouent des rôles différents, ce qui permet de rendre un certain nombre de questions accessibles à l’étude rigoureuse.Le chapitre 1 renforce le théorème d’indistinguabilité de Lyons et Schramm en percolation, lequel stipule que les composantes connexes infinies fournies par la percolation de Bernoulli sur un graphe de Cayley ont presque sûrement toutes la même allure. La non-Trivialité de ce renforcement est illustrée par un modèle dirigé qui vérifie la propriété d’indistinguabilité mais pas la propriété renforcée.Le chapitre 2 est le fruit d’un travail réalisé en collaboration avec Vincent Tassion.On y démontre que la valeur du paramètre critique pour la percolation de Bernoulli ne dépend essentiellement que de la structure locale du graphe de Cayley abélien considéré.Dans le chapitre 3, on introduit une version dirigée du modèle DLA, pour laquelle on établit l’existence d’une dynamique en volume infini, un contrôle sur la propagation d’information et des inégalités asymptotiques sur la largeur et la hauteur de l’agrégatThis thesis deals with two kinds of statistical mechanics problems: percolation ongroups and directed models. In the first case, we realise the group under considerationas a geometric object (via the notion of Cayley graph) before breaking it apartrandomly. The study of this process reveals deep connections between the geometricproperties of a group and the behaviour of Bernoulli percolation on it. In the secondcase, we focus on models where up and down play different roles, which makes severalquestions less hard to tackle.Chapter 1 strengthens the Indistinguishability Theorem of Lyons-Schramm, whichstates that the infinite clusters yielded by a Bernoulli percolation on a Cayley graphalmost surely all look alike. The non-Triviality of this strengthening is illustrated bya directed model that satisfies the Indistinguishability Property but not the StrongIndistinguishability Property.Chapter 2 has been obtained in collaboration with Vincent Tassion. We show thatthe value of the critical parameter for Bernoulli percolation essentially only dependson the local structure of the considered abelian Cayley graph.In Chapter 3, we introduce a directed version of the DLA model, for which weestablish the existence of an infinite volume dynamics, control the propagation ofinformation and prove asymptotic inequalities on the width and height of the cluster

A importância da leishmaniose visceral no contexto da saúde pública tem aumentado na ultima década. A manifestação da leishmaniose visceral nos cães é variável e estudos sobre a genética e a sua relação com a leishmaniose visceral têm indicado alguns genes envolvidos na susceptibilidade e resistência a esta doença. O objetivo deste estudo foi avaliar a relação entre as variantes alélicas dos gene Slc11a1 (solute carrier family 11 member 1) e DLA-DRB1 (dog leukocyte antigen) com a positividade para leishmaniose, determinada por meio da amplificação de DNA de cinetoplasto de Leishmania sp., por PCR, e pela presença de anticorpos anti-Leishmania sp. ao teste ELISA indireto. Foram observadas associações estatisticamente significantes entre a positividade para leishmaniose e: i. a presença do alelo (141, 145 ou 149) da região microssatélite (TAAA)n localizada no íntron 1 do gene Slc11a1 (P< 0,0001) ii. a variação do número de guaninas (8 ou 9 G) da região promotora (P=0,0280) (em ambos os casos quando analisados separadamente) e iii. a presença de qualquer dos alelos da região microssatélite associado a 8 ou 9 G da região promotora (P= 0,0025). A presença do alelo 141 foi estatisticamente associada à negatividade em cães (P<0,0001). Não foi observada associação estatisticamente significante entre a positividade à leishmaniose e a freqüência dos alelos do exon 2 do gene DLA- DRB1, embora tenha sido observada associação significante entre a freqüência dos alelos DRB1-W, DRB1*00101 ou DRB1-T e o resultado negativo para leishmaniose, podendo ser estes potenciais marcadores para resistência à leishmaniose em cães

We observed statistically significant associations between the leishmaniasis positive diagnosis and i. the presence of intron 1 microsatellite region alleles (141, 145 or 149) (P<0.0001), ii. the variation on the guanine number (8 or 9) in the promoter region (P=0.0280) (in both cases when analyzed separately), iii. the presence any of the microsatellite alleles associated to 8 or 9 G in the promoter region (P=0.0025). Microsatellite allele 141 was associated to negativity to leishmaniasis (P<0.0001). There was no association between the presence of any of the exon 2 DLA-DRB1 alleles and the leishmaniasis positive animals, although significant association between the frequency of the alleles DRB1-W, DRB1*00101 or DRB1-T and negative results to leishmaniasis were observed. These might be potential markers for dog’s resistance to visceral leishmaniasis

Full textAbstract:
O presente trabalho tem por objetivo apresentar, analisar e discutir as relações estabelecidas de Stefan Zweig no período de exílio, utilizando sua correspondência entre 1940 e 1942. Grande escritor de cartas, Zweig possui uma vasta correspondência com escritores, intelectuais, editores, amigos e familiares; existem cartas já publicadas, em edições desde a década de 1960, mas muitas ainda encontram-se inéditas em arquivos na Europa, na América do Sul e na América do Norte. Nesse sentido, o presente trabalho se dividiu em três partes: primeira parte de coleta documental, in loco, em dois arquivos, a citar o Deutsches Literaturarchiv Marbach, DLA, localizado na cidade de Marbach a. N., na Alemanha e o Arquivo da Biblioteca Nacional, BN, no Rio de Janeiro, Brasil; a segunda parte foi a leitura das cartas e separação de um primeiro corpus, o qual foi traduzido. Na primeira seleção, foram levados em conta aspectos que pudessem ressaltar as relações de Zweig com escritores e personalidades da época, europeus, norte-americanos e brasileiros, e cujo conteúdo pudesse trazer elementos para posterior análise; e a terceira parte do trabalho constituiu no desenvolvimento da dissertação e a análise em si das cartas, as quais puderam ser separadas em três núcleos temáticos em comum: (i) Zweig entre o Mundo de Ontem e o País do Futuro; (ii) Zweig e a literatura; e (iii) Zweig em seu isolamento. Como base teórica do trabalho foi utilizado um texto escrito por Zweig, Kunst des Briefes, no qual ele discute as características pertinentes ao gênero epistolar e o estatuto literário da carta. Textos teóricos de epistolografia também foram utilizados para dar suporte à base teórica do trabalho.This work aims to present, analyze and discuss relations established by Stefan Zweig during this exile time, by using his letters between 1940 and 1942. A great letter writer, Zweig has a great number of letters with intellectuals, editors, friends, relatives; there are some letters which have already been published, in editions since 1960s, but there are many that are still unpublished and are kept in archives in Europa, South America and North America. Therefore this work was divided in three parts: the first part was the in loco documental research in two archives e.g. Deutsches Literaturarchiv Marbach, DLA, located in Marbach a. N. city, in Germany and Arquivo da Biblioteca Nacional, BN, in Rio de Janeiro, Brazil; the second part was to read and separate the letters from a first corpus, which was totally translated to Portuguese. On this first selection aspects were taken into account, that could show the relations between Zweig and European, American and Brazilian writers and intellectuals from his epoch, and that had a content which could have brought elements for the afterward analysis; and the third part was composed by the letters analysis itself, which could be separated in three different thematic groups: (i) Zweig between the World of Yesterday and the Land of the Future; (ii) Zweig and the literature; e (iii) Zweig in his own isolation. As theoretical basis a Stefan Zweigs text was used, called Kunst des Briefes, in which he discusses mainly characteristics about the letter genre and the literary status of the letter. Epistolography theoretical texts were also used to support this work.

Approved for public release; distribution is unlimited.As a consequence of recent Defense Management Review Decisions the Department of Defense (DoD) has consolidated the physical distribution functions for wholesale consumable materiel under the management of the Defense Logistics Agency (DLA) and recommended that current DLA stock location policies be reviewed. This thesis examines certain aspects of these policies. The primary focus was on how DLA is managing items which experience a large percentage of high priority requisitions. Initial analyses considered the magnitude of the high priority requisition problem by identifying all requisitions that were submitted to DLA during FY92 using Issue Priority Group (IPG) I designation and a specified Required Delivery Date (RDD). Then, the six top items from this group requisitioned by the Naval Aviation Depot, North Island (NADEP NI), California were selected for detailed case studies. This study found the current stockage location of these items was neither nearest the customer nor nearest the vendor. Additionally, the lack of on-hand inventory was the most significant common factor causing shipment delays of the items.

Hoje em dia, a formação das galáxias não está totalmente compreendida. Acredita-se que foram formadas a partir de nuvens de alta densidade de hidrogênio neutro, com diferentes graus de metalicidade. Estas nuvens acham-se em maior número em redshifts (z)altos (2 - 4.5). Devido a suas baixas luminosidades, é difícil descobrí-las, de forma isolada. Na obtenção de espectros de Quasares (Quasi Stellar Objects - QSO's), observou-se a influência dessas nuvens na presença de linhas largas de absorção Ly a. Este sistema de linhas é denominado de "Sistemas Ly a Amortecidos" (Damped Lyman Alpha Systems ou DLA's). A importância do estudo dos DLA's está em entender melhor a formação e evolução das galáxias. Neste trabalho procurou-se estabelecer em quais regiões do espectro a radiação do DLA pode ser dominante, com uma razão Sinal/Ruído (S/N)superior a 3. Para utilizamos o software IRAF. Com ele simulou-se a absorção devida a galáxias de diferentes tipos espectrais e idades em vários espectros de QSO's, variando o redshift dos dois tipos de objetos. Encontramos quais devem ser os melhores filtros a serem usados nos telescópios de alta resolução Gemini e SOAR, dos quais participa o Brasil.Nowdays, the formation of galaxies it is not totally understood. It is believed that they were formed from huge clouds of neutral hydrogen, with different metallicity levels. These clouds are found in high redshifts (z > 2)and due to their low luminosity, it's difficult to discover them isolated. By obtaining spectra from QSO's (Quasi Stellar Objects), the influence of these clouds has been observed in the presence of broad Lyman alpha absortion lines. Because the systems responsible for these lines were not well known, they were called: "Damped Lyman Alpha Systems" (DLA's). By studying DLA's, we will learn how galaxies are formed and how they evolve. In this work we found which regions in a QSO - DLA spectrum, it may be possible to detect the DLA image at S/N levels greater than 3. To do this, simulations were made with IRAF using spectral templates of QSO's and of galaxies with different ages, spectral types and redshifts. We established then the photometric bands for extracting images of DLA's and some strategies to be used with the telescopes like GEMINI and SOAR, constructed in Cerro Pachón, in Chile, in which Brazil has a participation.

Full textAbstract:
This thesis compares the performance and robustness of five different varities of discriminant analysis, namely linear (LDA), quadratic (QDA), generalized quadratic (GQDA), diagonal linear (DLDA) and diagonal quadratic (DQDA) discriminant analysis, under elliptical distributions and small sample sizes. By means of simulations, the performance of the classifiers are compared against separation of mean vectors, sample size, number of variables, degree of non-normality and covariance structures. Results show that QDA is competitive under most settings, but can be outperformed by other classifiers with increasing sample size and when the covariance structures across classes are similar. Other noteworthy results include sensitivity of DQDA to non-normality and dependence of the performance of GQDA on whether sample sizes are balanced or not.

This thesis examines the Planning and Resource Management Department of the Defense Distribution Region West (DDRW) in their pursuit of introducing Activity Based Costing (ABC) to their organization. The thesis focuses on the workload impact of ABC on the department by developing a model that establishes the baseline workloads and costs. The model is created by the aid of a computer modeling software that incorporates the various physical constraints with the financial costs and variable external demands or requirements involved. With the baseline model completed, the anticipated ABC impact is introduced to the model and the results are assessed. This thesis answers the question as to the scope of the ABC impact on the DDRW Planning and Resource Management Department and demonstrates how ABC modeling can be an effective management tool. The model and the resulting analysis demonstrate both the strengths of ABC management for federal agencies and the viability of using computer model analysis in financial management decisions

Full textAbstract:
Viscous fingering occurs when one fluid displaces another fluid of a greater viscosity in a porous medium or a Hele-Shaw cell. Linear stability analysis is used to predict methods of suppressing instability. Then, experiments in which nonlinear growth dominates pattern formation are analysed to explore the nonlinear impact of strategies of suppressing finger growth. Often, chemical treatment fluid is injected into oil reservoirs in order to prevent sand production. This treatment fluid is usually followed by water injection to clean up the well. We explore the potential for viscous instability of the interface between the treatment fluid and the water, and also the treatment fluid and the oil, as a function of the volume of treatment fluid and the injection rate and viscosity ratios of the different fluids. For a given volume of treatment fluid and a given injection rate, we find the optimal viscosity of the treatment fluid to minimise the viscous instability. In the case of axisymmetric injection, the stabilisation associated with the azimuthal stretching of modes leads to a further constraint on the optimisation of the viscosity. In the case of oil production, polymers may be added to the displacing water in order to reduce adverse viscosity gradients. We also explore the case in which these polymers have a time-dependent viscosity, for example through the slow release from encapsulant. We calculate the injection flow rate profile that minimises the final amplitude of instability in both rectilinear and axisymmetric geometries. In a development of the model, we repeat the calculation for a shear-thinning rheology. Finally, experiments are analysed in which the nonlinear growth of viscous fingers develops to test the influence of different injection profiles on the development of instability. Diffusion Limited Aggregation (DLA) simulations are performed for comparison. In all cases, the evolving pattern has a saturation distribution, with an inner zone in which the fingers are static and an outer zone in which the fingers advance and grow. In the very centre of the viscous fingering patterns, there is a small fully-saturated region. In the experiments, the mass distribution in the inner zone varies with radius as a power law which relates to the fractal dimension for the analogue DLA simulations. In the outer region the saturation decreases linearly with radius. The radius of the inner frozen zone is approximately 2/3 of the outer radius in the cases of DLA and -- after a period of evolution -- the viscous fingering experiments. This allows the radial extents of the inner and outer zones to be predicted. The ratio of each radius to the extent of the fully-saturated region is independent of the injection profile and corresponds to values for DLA.

O atual estágio de desenvolvimento econômico brasileiro mostra-se favorável ao emprego, em maior escala, da tecnologia de geração distribuída. Isto se deve, em parte, ao aumento da demanda de energia elétrica, maior disponibilidade de gás natural, tarifas diferenciadas para os horários de ponta, entre outros atrativos. Uma alternativa para geração elétrica, em franco desenvolvimento, são as microturbinas que operam na faixa de 25 a 1000 kW. O presente trabalho consistiu no desenvolvimento e caracterização de uma câmara de combustão de microturbinas a gás do tipo DLN – Dry Low NOx com tecnologia LPP – Lean Premixed Prevaporized. Os principais objetivos foram: projetar e caracterizar queimadores individuais que operem no modo ultra-pobre, com chama estabilizada por gerador de vórtices (swirler); dimensionar o tubo de chama do combustor de forma a operar no modo pré-misturado; projetar o queimador piloto para transição do modo de queima pobre para pré-misturado e auxiliar a estabilidade operacional da câmara nos diversos regimes de carga; instrumentar adequadamente a bancada de microturbina para a caracterização dos queimadores e do envelope operacional da unidade em diferentes níveis de “carga”; caracterizar o conjunto de queimadores pobre, queimador piloto de pré-mistura e, por último, avaliar a transição entre modos de operação (ultra pobre e pré-misturado). Após a identificação do envelope de estabilidade operacional do combustor, variaram-se alguns parâmetros do processo na busca da minimização dos índices de emissões de NOx e CO. Em regime estável, nos melhores casos, obteve-se menos de 23 ppm de NOx, corrigido para 15% de O2 e menos de 67 ppm de CO, também corrigido para 15% de O2. _______________________________________________________________________________________ ABSTRACT
The actual economic development stage Brazilian is favorable to the employment, on a larger scale, of the distributed generation technology. This is due, in part, to the increase in electricity demand, greater availability of natural gas, differentiated rates for the pick load times, among others. An alternative for electricity generation, in continuous growth, are the microturbines which covers de power range from 25 to 1000 kW. The present work consisted on the development and characterization of a combustion chamber of microturbine gas generator of the type DLN (Dry Low NOx) based on LPP (Lean Premixed Prevaporized) technology. The main objectives were: to design and to characterize individual burners to operate in lean mode with the flame stabilized by means of a swirler device; to design the fire tube to operate in premixed combustion mode; to design the pilot burner for the transition between operating modes as well as to help stabilize the flame at several load regimes; to set an appropriate instrumentation for the apparatus as to facilitate burners and unit operational range characterization, to investigate the performance of the lean, pilot and premixed burners, and, lastly, to evaluate the stability of the system when changing the regime of operation (lean-lean to premixed). After identification of the stable operational range of the gas turbine combustor some process parameters were varied in searching for low emissions of NOx and CO. In stable regimes, for the best cases, it was obtained less than 23 ppm of NOx, corrected to 15% O2 and less than 67 ppm of CO, also corrected to 15% O2.

Full textAbstract:
Cette thèse contient quatre travaux sur le modèle d'Agrégation Limitée par Diffusion Interne (iDLA), qui est un modèle de croissance pour la construction récursive d'ensembles aléatoires. Le premier travail concerne la dimension 1 et étudie le cas où les marches aléatoires formant l'agrégat évoluent dans un milieu aléatoire. L'agrégat normalisé converge alors non pas vers une forme limite déterministe comme dans le cas de marches aléatoires simples mais converge en loi vers un segment contenant l'origine dont les extrémités suivent la loi de l'Arcsinus. Dans le deuxième travail, on considère le cas où l'agrégat est formé par des marches aléatoires simples en dimension d > 1. On donne alors des résultats de convergence et de fluctuations sur la fonction odomètre introduite par Levine et Peres, qui compte en chaque point le nombre de passages des marches ayant formé l'agrégat. Dans le troisième travail, on s'intéresse au cas où l'agrégat est formé par des marches aléatoires multidimensionnelles qui ne sont pas centrées. On montre que sous une normalisation appropriée, l'agrégat converge vers une forme limite qui s'identifie à une vraie boule de chaleur. Nous répondons ainsi à une question ouverte en analyse concernant l'existence d'une telle boule bornée. Le quatrième travail concerne le cas particulier où une borne intérieure est connue pour l'agrégat. On donne alors des conditions suffisantes sur le graphe ainsi que sur la nature de cette borne pour qu'elle implique une borne extérieure. Ce résultat est appliqué au cas de marches évoluant sur un amas de percolation par arêtes surcritique, complétant ainsi un résultat de ShellefThis thesis contains four works on the Internal Diffusion Limited Aggregation model (iDLA), which is a growth model that recursively builds random sets. The first work is set in dimension 1 and studies the case where the random walks that build the aggregate evolve in a random environment. The normalised aggregate then does not converges towards a deterministic limiting shape as it is the case for simple random walks, but converges in law towards a segment that contains the origin and which extremal points follow the Arcsine law. In the second work, we consider the case where the aggregate is built by simple random walks in dimension d > 1. We give convergence and fluctuation results on the odometer function introduced by Levine and Peres, which counts at each point the number of visits of walkers throughout the construction of the aggregate. In the third work, we examine the case where the aggregate is built using multidimensional drifted random walks. We show that under a suitable normalisation, the aggregate converges towards a limiting shape which is identified as a true heat ball. We thus give an answer to an open question in analysis concerning the existence of such a bounded shape. The last work deals with the special case where an interior bound is known for the aggregate. We give a set of conditions on the graph and on the nature of this interior bound that are sufficient to imply an outer bound. This result is applied to the case of random walks on the supercritical bond percolation cluster, thus completing a result by Shellef

A amostra para o segundo grupo, controle, abrangeu 50 mulheres, com 60 anos ou mais de idade, não praticantes de exercício físico e o levantamento amostral foi realizado em igrejas, feiras, supermercados, comércio dos bairros da região considerada, Unidade Básica de Saúde, assim como em residências. Para este comparativo, foram realizadas as coletas de dados antropométricos (peso, altura, circunferência do braço (CB), da cintura (CC), do quadril (CQ) e da panturrilha (CP) e prega cutânea tricipital (PCT)). Foram aplicados formulários com informação sobre dados pessoais, socioeconômicos, de saúde e atividades físicas. O desempenho funcional foi obtido através da aplicação de cinco testes motores: sentar, levantar-se da cadeira e locomover-se pela casa; levantar-se do solo; calçar meias; subir escadas e caminhar/correr 800 metros. Pôde-se constatar, na comparação entre o grupo de idosas praticantes regulares de exercício físico e o grupo controle, que o desempenho funcional foi muito superior em quatro dos cinco testes motores, no primeiro grupo em relação ao segundo, apesar das semelhanças, quanto às condições socioeconômicas, perfil nutricional e de saúde dos dois grupos.Abstract: The objective of this study is to characterize and compare the socioeconomic status, nutritional profile and functional performance of elderly women who regularly exercise and those who have no regular physical activities. All these women are physically independent and reside in the Northern part of the city of São José do Rio Preto - SP. Field research sampling of the first group, the observation group, consisted of 60 elderly women, aged ≥ 60, who, for at least two years, attended a special gym class at a NGO (Non-Governmental Organization): PAE - Action and Education Program. The sampling of the second group, the control group, encompassed 50 women, aged ≥ 60, who did not practice physical exercises. The sampling survey data for this group was gathered at churches, open street fairs, supermarkets, shops in neighborhoods in the Northern part of the city, Primary Health Care Units, as well as in their houses. For this comparison, anthropometric data was obtained (weight, height or stature (ST), arm muscle circumference (AMC), waist (WC), hip (HC) and calf (CC) circumferences and triceps skin fold thickness (TST)). Forms contained personal information, data on socioeconomic status, health and physical activities practiced. Functional performance evaluation was obtained through the application of five motor skill tests: sitting, getting up from a chair and moving about the house; getting up from the ground; putting on socks; climbing stairs and walking/running 800 meters. The results of the performance of elderly women, when comparing the group that regularly exercised with the control group, was that the performance of the first group was superior to the second group in four of the five motor skill tests, even though socioeconomic, nutritional and health profiles of the women in two groups were similar.

Full textAbstract:
The aetiology of autoimmune disease is a complex interplay between genetics, environment and immunological regulation. Our understanding of the genetic aspects of autoimmunity has increased with recent findings from Genome Wide Association Studies (GWAS). There is now a movement towards meta-analyses of GWA studies in order to increase the number of genetic loci detected. There are also efforts to detect common genetic risk factors amongst groups of diseases that potentially share common aetiopathogenic pathways. Animal models have formed the basis of many genetic discoveries and the domestic dog presents a spontaneous model for many diseases, including autoimmunity. Through man’s efforts to create specific breeds, the dog has acquired a genomic architecture consisting of long haplotype blocks and extensive linkage disequilibrium. This means that a GWAS can be conducted in dog breeds with fewer samples and fewer markers than an equivalent study in humans, reducing costs, cohort collection times, and data handling/storage considerations. Successful canine GWA studies are now starting to be published. Building upon this success, the findings from GWA studies in three canine autoimmune diseases (across six different breeds), with equivalent human pathologies, are presented. Dogs with diabetes mellitus (similar to latent autoimmune diabetes of adulthood in man), lymphocytic thyroiditis (similar to Hashimoto’s thyroiditis), and anal furunculosis (similar to perianal Crohn’s disease) were compared to control dogs to identify genetic susceptibility loci underlying disease. Follow-up genotyping of the top hits from the GWAS analyses were conducted to replicate findings and to better characterise the diseases across a number of dog breeds. Typing of MHC class II genes, important in the immune response, was also undertaken in canine diabetes mellitus and canine lymphocytic thyroiditis. In anal furunculosis, high-throughput, next-generation sequencing was utilised to identify novel mutations and fine-map associations at discovered loci. Several genes were identified in all of these canine autoimmune diseases, many with good candidate function. Some of these genes indicated common genetic susceptibility loci and pathways between canine autoimmune diseases. Breed-specific genetic effects underlying canine diabetes mellitus and canine lymphocytic thyroiditis were identified, which has implications for disease diagnosis and clinical management. Novel loci for investigation in the corresponding human disease studies have been identified and future work will begin to genetically link the conditions in dog and man.

Approved for public release; distribution in unlimited.In a warehouse, a fast-pick-area is a region containing many items that can be retrieved quickly and inexpensively to fulfill customer orders. The Defense Distribution Center San Joaquin (DDJC) implements a similar strategy on a wider scale by designating one of many warehouses as a "fast-pick-area." We develop a plan to optimally slot the fast-pick area at DDJC using a computer model that captures the tradeo.s of storage space versus cost of replenishment from bulk storage. Our results suggest that defense distribution centers should consider implementing a fast pick area as a means of reducing operating costs.
