A presente dissertação de mestrado teve como fenômeno de estudo a Ênfase em Gestão do Patrimônio Socioambiental do curso de História Bacharelado da Universidade Federal do Rio Grande – FURG, buscando compreender o processo de constituição e desenvolvimento desta Ênfase e suas articulações com a Educação Ambiental. Para tanto, foram elencadas três hipóteses: (a) a Ênfase em Gestão do Patrimônio Socioambiental do curso de Bacharelado em História da FURG não é estruturada e nem desenvolvida a partir das emergências da crise estrutural da qual a crise ambiental é um aspecto latente; (b) os saberes desenvolvidos na Ênfase não possibilitam que o egresso desenvolva a criticidade e a formação necessária para o cumprimento de sua função socioambiental; (c) a Educação Ambiental desenvolvida na Ênfase em Gestão do Patrimônio Socioambiental do curso de História – Bacharelado da Universidade Federal do Rio Grande – FURG não é expressão de uma ciência que se pretenda a serviço da classe trabalhadora e que se proponha a encarar os desafios das questões impostas pela crise ambiental. Em decorrência destas, foi desenvolvido um objetivo geral e três objetivos específicos, sendo eles: (a) Entender as condições sociais de crise ambiental em meio as quais surge a necessidade de gestores do patrimônio socioambiental; (b) Analisar os aspectos teóricos do campo da Educação Ambiental e a compreensão de ciência presentes na formação dos gestores do patrimônio socioambiental; (c) Identificar, no Projeto Pedagógico do curso de História Bacharelado, os aspectos políticos que demonstrem a função social do egresso. Ainda no sentido de atender ao objetivo geral foram organizadas quatro questões de pesquisa, a saber: (a) Quais as emergências da necessidade de criação da Ênfase em Gestão do Patrimônio Socioambiental no curso de História - Bacharelado da Universidade Federal do Rio Grande - FURG? (b) Que perspectiva de Educação Ambiental tem os professores da Ênfase em Gestão do Patrimônio Socioambiental do curso de História - Bacharelado da Universidade Federal do Rio Grande - FURG? (c) Que compreensão de ciência e de Educação Ambiental está vinculada à formação dos egressos da Ênfase em Gestão do Patrimônio Socioambiental do curso de História - Bacharelado da Universidade Federal do Rio Grande - FURG? (d) Quais saberes são fundamentais na formação dos gestores do patrimônio socioambiental para que compreendam os fundamentos da crise que faz emergir a necessidade da função social de tal ênfase? Nesta pesquisa foram utilizados, prioritariamente, os referenciais teóricos e epistemológicos com vinculação à compreensão de mundo marxista. Após o processo de revisão bibliográfica foram desenvolvidas entrevistas semi-estruturadas com sete professores atuantes na ênfase em estudo. Na sequência, para apreciação das informações, foi utilizado o referencial metodológico da Análise de Conteúdo de Laurence Bardin. Concluiu-se no processo de pesquisa que a ênfase se relaciona com a oferta de novas possibilidades de atuação profissional do historiador gestor. Bem como os saberes desenvolvidos na ênfase possibilitam parcialmente a constituição da criticidade dos egressos. Por fim, a Educação Ambiental desenvolvida na ênfase não pode, em sua totalidade, estar a serviço da classe trabalhadora, pois está circunscrita, no presente momento histórico, aos limites do Capital.

During the Sedimentation of the platform carbonate deposits of the Korallenoolith Formation (middle Oxfordian to early Kimmeridgian) small buildups ofcorals formed in the Lower Saxony Basin. These bioconstructions are restricted to particular horizons (Untere Korallenbank,ßorigenuna-Bank Member etc.) and represent patch reefs and biostromes. In this study, the development of facies, fossil assemblages, spatial distribution of fossils, and reefs of the ßorigenuna-Bank Member (upper Middle Oxfordian) in the Süntel Mts and the eastern Wesergebirge Mts is described; the formation of reefs is discussed in detail. Twelve facies types are described and interpreted. They vary between high-energy deposits as well winnowed oolites and quiet-water lagoonal mudstones. Owing to the significance of biota, micro- and macrofossils are systematically described. The reefs are preserved in growth position, are characterized by numerous corresponding features and belong to a certain reef type. According to their size, shape and framework, they represent patch reefs, coral knobs (sensu James, 1983), coral thrombolite reefs (sensu Leinfelder et al., 1994) or “Klein- and Mitteldickichte” (sensu Laternser, 2001). Their growth fabric corresponds to the superstratal (dense) pillarstone (sensu Insalaco, 1998). As the top of the ßorigenuna-Bank displays an erosional unconformity (so-called Hauptdiskontinuität), the top of the reefs are erosionally capped. Their maximum height amounts to at least the maximum thickness of the ßorigenuna-Bank which does not exceed 4 metres. The diversity of coral fauna of the reefs is relatively low; a total of 13 species is recorded. The coral community is over- whelmingly dominated by the thin-branched ramose Thamnasteria dendroidea (Lamouroux) that forms aggregations of colonies (77?. dendroidea thickets). Leafy to platy Fungiastrea arachnoides (Parkinson) and Thamnasteria concinna (Goldfuss) occur subordinately, other species are only of minor importance. In a few cases, the reef-core consisting of Th. dendroidea thickets is laterally encrusted by platy F. arachnoides and Th. concinna colonies, and microbial carbonates. This zonation reflects probably a succession of different reef builders as a result of changing environmental conditions (allogenic succession). Moreover, some reefs are overlain by a biostrome made of large Solenopora jurassica nodules passing laterally in a nerinean bed. Mikrobial carbonates promoted reef growth and favoured the preservation of reef organismn in their growth position or in situ. They exhibit a platy, dendroid, or reticulate growth form or occur as downward-facing hemispheroids. According to their microstructure, they consist of a peloidal, clotted, or unstructured fabric (predominately layered and poorly structured thrombolite as well as clotted leiolite) (sensu Schmid, 1996). Abundant endo- and epibiontic organisms (bivalves, gastropods, echinoids, asteroids, ophiuroids, crabs etc) are linked to the reefs. With regard to their guild structure, the reefs represent occurrences at which only a few coral species serve as builder. Moreover, microbial carbonates contribute to both building and binding of the reefs. Additional binder as well as baffler are present, but not abundant. According to the species diversity, the dweller guild comprises by far the highest number of invertebrate taxa. The destroyer guild chiefly encompasses bivalves. The composition of the reef community was influenced by the habitat structure of the Th. dendroidea thickets. Owing to the increase in encrusting organisms and other inhabitants of the thickets, the locational factors changed, since light intensity and hydrodynamic energy level and combined parameters as oxygen supply declined in the crowded habitat. Therefore a characteristic succession of organisms is developed that depends on and responds to changing environmental conditions („community replacement sequence“). The succession allows the differentiation of different stages. It started after the cessation of the polyps with boring organisms and photoautotrophic micro-encrusters (calcareous algae, Lithocodium aggregatum). Following the death of these pioneer organisms, encrusting and adherent organisms (serpulids, „Terebella“ species, bryozoans, foraminifers, thecideidinids, sklerospongid and pharetronid sponges, terebratulids), small mobile organisms (limpets), and microbial induced carbonates developed. The final stage in the community replacement sequence gave rise to small cryptic habitats and organisms that belong to these caves (cryptobionts, coelobites). The habitat conditions especially favoured small non-rigid demosponges (“soft sponges”) that tolerate reduced water circulation. Reef rubble is negligible, so that the reefs are bordered by fossiliferous micritic limestone passing laterally in micritic limestone. Approximately 10% of the study area (outcropping florigemma-Bank) corresponds to reefal deposits whereas the remaining 90% encompass lagoonal inter-reefal deposits. The reef development is a good example for the interaction between reef growth, facies development and sea-level changes. It was initiated by a sea-level rise (transgression) and corresponding decrease in the hydrodynamic energy level. Colonization and reef growth took place on a coarse-grained Substrate composed of oncoids, larger foraminifers and bioclasts. Reef growth took place in a calm marine lagoonal setting. Increasing abundance of spherical coral morphs towards the Northeast (section Kessiehausen, northwestem Süntel Mts) reflects higher turbidity and a facies transition to coral occurrences of the ßorigenuna-Bank Member in the adjacent Deister Mts. The reef growth was neither influenced by stonns nor by input of siliciclastic deposits, and took place in short time - probably in only a thousand years under most probably mesotrophic conditions. The mass appearance of solenoporids and nerineids in the upper part of the ßorigenuna-Bank Member point to enhanced nutrient level as a result of regression. In addition, this scenario of fluctuations in nutrient availability seems to be responsible for the cessation of reef corals. The sea level fall reached its climax in the subaerial exposure and palaeokarst development of the florigemma-Bank. The reef building corals are typical pioneer species. The blade-like, flattened F. amchnoides colonies are characterized by their light porous calcium carbonate skeleton, which is a distinct advantage in soft bottom environment. Thus, they settled on soft bottom exposing the large parts of its surface to the incoming light. On the other hand, in response to their light requirements they were also able to settle shaded canopy structures or reef caves. Th. dendroidea is an opportunistic coral species in very shallow, well illuminated marine environment. Their thin and densely spaced branches led to a very high surface/volume ratio of the colonies that were capable to exploit incoming light due to their small thamasterioid calices characterized by “highly integrated polyps”. In addition, sideward coalescence of branches during colony growth led to a wave-resistant framework and favoured the authochthonous preservation of the reefs. Asexual reproduction by fragmented colonies promoted reef development as Th. dendroidea thickets laterally extend over the sea floor or new reefs have developed from broken fragments of parent colonies. Similar build ups with Th. dendroidea as a dominant or frequent reef building coral species are known from the Paris Basin and elsewhere from the Lower Saxony Basin (Kleiner Deister Mts). These buildups developed in well-illuminated shallow water and encompass coral reefs or coral thrombolite reefs. Intra- and inter-reef deposits vary between well-winnowed reef debris limestone and mudstones representing considerably calmer conditions. Solenoporid, nerineids and diceratides belong to the characteristic fossils of these occurrences. However, diceratides are missing in theflorigemma-Bank Member. Th. dendroidea differs in its colonization of low- to high-energy environment from recent ramose scleractinian corals (e.g., Acropora and Porites sp.). The latter are restricted to agitated water habitats creating coral thickets and carpets. According to the morphologic plasticity of Th. dendroidea, thick-branched colonies developed in a milieu of high water energy, whereas fragile, wide- and thin-branched colonies prevail in low-energy settings. Due to its relatively rapid growth, Th. dendroidea was able to keep pace with increased Sedimentation rates. 68 benthonic foraminiferan species/taxa have been recognized in thin sections. Agglutinated foraminifers (textulariids) predominate when compared with rotaliids and milioliids. Numerous species are restricted to a certain facies type or occur in higher population densities, in particular Everticyclammina sp., a larger agglutinated foraminifer that occurs in rock building amounts. Among the 25 reef dwelling foraminiferal species, a few were so far only known from Late Jurassic sponge reefs. Another striking feature is the frequency of adherent foraminiferal species. Fauna and flora, in particular dasycladaleans and agglutinated foraminifers, document palaeobiogeographic relationships to the Tethys and point to (sub)tropical conditions. Moreover, in Germany this foraminiferan assemblage is yet uncompared. In Southern Germany similar tethyan type assemblages are not present in strata as young as Middle Tithonian.

O presente Relatório Final de Estágio foi desenvolvido no âmbito da unidade curricular de Prática de Ensino Supervisionada III (PES III) do 2.º Ciclo de Estudos, do Mestrado em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico e inclui duas partes distintas. A primeira parte diz respeito às práticas de estágio desenvolvidas no decorrer da unidade curricular Prática de Ensino Supervisionada (PES). Aí, proceder-se-á a uma reflexão crítica acerca do trabalho desenvolvido nos referidos contextos e das experiências de aprendizagem que daí resultaram. A segunda parte do relatório final de estágio está relacionada com a execução de um trabalho de investigação centrado nos seguintes objetivos: compreender a importância da frequência da creche no desenvolvimento e aprendizagem das crianças, identificar a opinião dos profissionais sobre a creche e as suas atividades e conhecer a relação pais/Jardim-de-Infância/Creche. O estudo em causa segue uma metodologia qualitativa, mais concretamente o estudo de caso e envolve duas educadoras de creche, três educadoras do jardim-de-infância, nove pais das crianças da creche e sessenta e uma crianças (9 responderam às entrevistas acerca da frequência da creche e 52 executaram o desenho alusivo à visita à sala de creche). Com a realização deste trabalho de investigação pretende-se acima de tudo obter resposta à seguinte questão: “Qual a importância da frequência da Creche na transição para o Jardim-de-Infância?” Tendo em conta o estudo realizado foi possível obter determinadas conclusões de acordo com as perpetivas dos profissionais (educadoras de creche e educadoras do jardim-de-infância), pais e crianças do jardim-de-infância. No parecer dos profissionais a creche é importante no sentido de autonomia (gerir a separação dos pais), em termos de regras, altruísmo e partilha de brinquedos, bem como o desenvolvimento global das crianças. Os pais consideram que a creche proporciona o desenvolvimento pessoal e aprendizagem das crianças. Para além disto, a mesma permite educar os seus filhos e é a primeira etapa da educação escolar. Porém, existem pais que referem que o facto de deixarem os seus filhos na referida instituição está relacionado com a inexistência de tempo da sua parte.De acordo com as entrevistas realizadas às crianças do jardim-de-infância podemos verificar que a frequência da creche foi fundamental para o crescimento saudável das crianças, sendo que 89% das crianças têm lembranças positivas sobre o primeiro dia de creche, 57% das crianças menciona como atividades que mais gostavam brincar com as bolas, 100% mencionaram que preferem brincar com outras crianças, 78% revelaram a existência de uma interação positiva entre as mesmas e a educadora, bem como 100% afirmou existir reações positivas à participação dos pais nas suas atividades.

This thesis is a research about the recent complex spatial changes in Namibia and Tanzania and local communities’ capacity to cope with, adapt to and transform the unpredictability engaged to these processes. I scrutinise the concept of resilience and its potential application to explaining the development of local communities in Southern Africa when facing various social, economic and environmental changes. My research is based on three distinct but overlapping research questions: what are the main spatial changes and their impact on the study areas in Namibia and Tanzania? What are the adaptation, transformation and resilience processes of the studied local communities in Namibia and Tanzania? How are innovation systems developed, and what is their impact on the resilience of the studied local communities in Namibia and Tanzania? I use four ethnographic case studies concerning environmental change, global tourism and innovation system development in Namibia and Tanzania, as well as mixed-methodological approaches, to study these issues. The results of my empirical investigation demonstrate that the spatial changes in the localities within Namibia and Tanzania are unique, loose assemblages, a result of the complex, multisided, relational and evolutional development of human and non-human elements that do not necessarily have linear causalities. Several changes co-exist and are interconnected though uncertain and unstructured and, together with the multiple stressors related to poverty, have made communities more vulnerable to different changes. The communities’ adaptation and transformation measures have been mostly reactive, based on contingency and post hoc learning. Despite various anticipation techniques, coping measures, adaptive learning and self-organisation processes occurring in the localities, the local communities are constrained by their uneven power relationships within the larger assemblages. Thus, communities’ own opportunities to increase their resilience are limited without changing the relations in these multiform entities. Therefore, larger cooperation models are needed, like an innovation system, based on the interactions of different actors to foster cooperation, which require collaboration among and input from a diverse set of stakeholders to combine different sources of knowledge, innovation and learning. Accordingly, both Namibia and Tanzania are developing an innovation system as their key policy to foster transformation towards knowledge-based societies. Finally, the development of an innovation system needs novel bottom-up approaches to increase the resilience of local communities and embed it into local communities. Therefore, innovation policies in Namibia have emphasised the role of indigenous knowledge, and Tanzania has established the Living Lab network.

Human and robots have complementary strengths in performing assembly operations. Humans are very good at perception tasks in unstructured environments. They are able to recognize and locate a part from a box of miscellaneous parts. They are also very good at complex manipulation in tight spaces. The sensory characteristics of the humans, motor abilities, knowledge and skills give the humans the ability to react to unexpected situations and resolve problems quickly. In contrast, robots are very good at pick and place operations and highly repeatable in placement tasks. Robots can perform tasks at high speeds and still maintain precision in their operations. Robots can also operate for long periods of times. Robots are also very good at applying high forces and torques. Typically, robots are used in mass production. Small batch and custom production operations predominantly use manual labor. The high labor cost is making it difficult for small and medium manufacturers to remain cost competitive in high wage markets. These manufactures are mainly involved in small batch and custom production. They need to find a way to reduce the labor cost in assembly operations. Purely robotic cells will not be able to provide them the necessary flexibility. Creating hybrid cells where humans and robots can collaborate in close physical proximities is a potential solution. The underlying idea behind such cells is to decompose assembly operations into tasks such that humans and robots can collaborate by performing sub-tasks that are suitable for them. Realizing hybrid cells that enable effective human and robot collaboration is challenging. This dissertation addresses the following three computational issues involved in developing and utilizing hybrid assembly cells: - We should be able to automatically generate plans to operate hybrid assembly cells to ensure efficient cell operation. This requires generating feasible assembly sequences and instructions for robots and human operators, respectively. Automated planning poses the following two challenges. First, generating operation plans for complex assemblies is challenging. The complexity can come due to the combinatorial explosion caused by the size of the assembly or the complex paths needed to perform the assembly. Second, generating feasible plans requires accounting for robot and human motion constraints. The first objective of the dissertation is to develop the underlying computational foundations for automatically generating plans for the operation of hybrid cells. It addresses both assembly complexity and motion constraints issues. - The collaboration between humans and robots in the assembly cell will only be practical if human safety can be ensured during the assembly tasks that require collaboration between humans and robots. The second objective of the dissertation is to evaluate different options for real-time monitoring of the state of human operator with respect to the robot and develop strategies for taking appropriate measures to ensure human safety when the planned move by the robot may compromise the safety of the human operator. In order to be competitive in the market, the developed solution will have to include considerations about cost without significantly compromising quality. - In the envisioned hybrid cell, we will be relying on human operators to bring the part into the cell. If the human operator makes an error in selecting the part or fails to place it correctly, the robot will be unable to correctly perform the task assigned to it. If the error goes undetected, it can lead to a defective product and inefficiencies in the cell operation. The reason for human error can be either confusion due to poor quality instructions or human operator not paying adequate attention to the instructions. In order to ensure smooth and error-free operation of the cell, we will need to monitor the state of the assembly operations in the cell. The third objective of the dissertation is to identify and track parts in the cell and automatically generate instructions for taking corrective actions if a human operator deviates from the selected plan. Potential corrective actions may involve re-planning if it is possible to continue assembly from the current state. Corrective actions may also involve issuing warning and generating instructions to undo the current task.

In this talk, we propose an all regime Lagrange-Projection like numerical scheme for the gas dynamics equations. By all regime, we mean that the numerical scheme is able to compute accurate approximate solutions with an under-resolved discretization with respect to the Mach number M, i.e. such that the ratio between the Mach number M and the mesh size or the time step is small with respect to 1. The key idea is to decouple acoustic and transport phenomenon and then alter the numerical flux in the acoustic approximation to obtain a uniform truncation error in term of M. This modified scheme is conservative and endowed with good stability properties with respect to the positivity of the density and the internal energy. A discrete entropy inequality under a condition on the modification is obtained thanks to a reinterpretation of the modified scheme in the Harten Lax and van Leer formalism. A natural extension to multi-dimensional problems discretized over unstructured mesh is proposed. Then a simple and efficient semi implicit scheme is also proposed. The resulting scheme is stable under a CFL condition driven by the (slow) material waves and not by the (fast) acoustic waves and so verifies the all regime property. Numerical evidences are proposed and show the ability of the scheme to deal with tests where the flow regime may vary from low to high Mach values.

This book is a synthesizing reflection on the Holocaust commemoration, in which space becomes a starting point for discussion. The author understands space primarily as an amalgam of physical and social components, where various commemorative processes may occur. The first part of the book draws attention to the material aspect of space, which determines its character and function. Material culture has been a long ignored and depreciated dimension of human culture in the humanities and social sciences, because it was perceived as passive and fully controlled by human will, and therefore insignificant in the course of social and historical processes. An example of the Nazi system perfectly illustrates how important were the restrictions and prohibitions on the usage of mundane objects, and in general, the whole material culture in relation to macro and micro space management — the state, cities, neighborhoods and houses, but also parks and swimming pools, factories and offices or shops and theaters. The importance of things and space was also clearly visible in exploitative policies present in overcrowded ghettos and concentration and death camps. For this very reason, when we study spatial forms of Holocaust commemoration, it should be acknowledged that the first traces, proofs and mementoes of the murdered were their things. The first "monuments" showing the enormity of the destruction are thus primarily gigantic piles of objects — shoes, glasses, toys, clothes, suitcases, toothbrushes, etc., which together with the extensive camps’ space try to recall the scale of a crime impossible to understand or imagine. The first chapter shows the importance of introducing the material dimension in thinking about space and commemoration, and it ends with a question about one of the key concepts for the book, a monument, which can be understood as both object (singular or plural) and architecture (sculptures, buildings, highways). However, the term monument tends to be used rather in a later and traditional sense, as an architectural, figurative form commemorating the heroic deeds, carved in stone or cast in bronze. Therefore, the next chapter reconstructs this narrower line of thinking, together with a discussion about what form a monument commemorating a subject as delicate and sensitive as the Holocaust should take on. This leads to an idea of the counter-monument, the concept which was supposed to be the answer to the mentioned representational dilemma on the one hand, and which would disassociate it from the Nazi’s traditional monuments on the other hand. This chapter clarifies the counter-monument definition and explains the misunderstandings and confusions generated on the basis of this concept by following the dynamics of the new commemorative form and by investigating monuments from the ‘80s and ‘90s erected in Germany. In the next chapter, I examine various forms of the Holocaust commemoration in Berlin, a city famous for its bold, monumental, and even controversial projects. We find among them the entire spectrum of memorials – big, monumental, and abstract forms, like Peter Eisenman’s Memorial to the Murdered Jews of Europe or Daniel Liebeskind’s Jewish Museum Berlin; flat, invisible, and employing the idea of emptiness, like Christian Boltanski’s Missing House or Micha Ullman’s Book Burning Memorial; the dispersed and decentralized, like Renata Stih and Frieder Schnock’s Memory Places or Gunter Demnig’s Stumbling Blocks. I enrich descriptions of the monuments by signaling at this point their second, extended life, which manifests itself in the alternative modes of (mis)use, consisting of various social activities or artistic performances. The formal wealth of the outlined projects creates a wide panorama of possible solutions to the Holocaust commemoration problems. However, the discussions accompanying the building of monuments and their "future life" after realization emphasize the importance of the social component that permeates the biography of the monument, and therefore significantly influences its foreseen design. The book also addresses the relationship of space, place and memory in a specific situation, when commemoration is performed secretly or remains as unrealized potential. Although place is the most common space associated with memory, today the nature of this relationship changes, and is what indicates popularity and employment of such terms as Marc Augé’s non-places or Pierre Nora’s site of memory. I include and develop these concepts about space and memory in my reflections to describe qualitatively different phenomena occurring in Central and Eastern European countries. These are unsettling places in rural areas like glades or parking lots, markets and playgrounds in urban settings. I link them to the post-war time and modernization processes and call them sites of non-memory and non-sites of memory. Another part of the book deals with a completely different form of commemoration called Mystery of memory. Grodzka Gate - NN Theatre in Lublin initiated it in 2000 and as a form it situates itself closer to the art of theater than architecture. Real spaces and places of everyday interactions become a stage for these performances, such as the “Jewish town” in Lublin or the Majdanek concentration camp. The minimalist scenography modifies space and reveals its previously unseen dimensions, while the actors — residents and people especially related to places like survivors and Righteous Among the Nations — are involved in the course of the show thanks to various rituals and symbolic gestures. The performance should be distinguished from social actions, because it incorporates tools known from religious rituals and art, which together saturate the mystery of memory with an aura of uniqueness. The last discussed commemoration mode takes the form of exposition space. I examine an exhibition concerning the fate of the incarcerated children presented in one of the barracks of the Majdanek State Museum in Lublin. The Primer – Children in Majdanek Camp is unique for several reasons. First, because even though it is exhibited in the camp barrack, it uses a completely different filter to tell the story of the camp in comparison to the exhibitions in the rest of the barracks. For this reason, one experiences immersing oneself in all subsequent levels of space and narrative accompanying them – at first, in a general narrative about the camp, and later in a specifically arranged space marked by children’s experiences, their language and thinking, and hence formed in a way more accessible for younger visitors. Second, the exhibition resigns from didacticism and distancing descriptions, and takes an advantage of eyewitnesses and survivors’ testimonies instead. Third, the exhibition space evokes an aura of strangeness similar to a fairy tale or a dream. It is accomplished thanks to the arrangement of various, usually highly symbolic material objects, and by favoring the fragrance and phonic sensations, movement, while belittling visual stimulations. The exhibition creates an impression of a place open to thinking and experiencing, and functions as an asylum, a radically different form to its camp surrounding characterized by a more overwhelming and austere space.

The purpose of this research is to study sedimentation mechanism by mathematical modeling in access channels which are affected by tidal currents. The most important factor for recognizing sedimentation process in every water environment is the flow pattern of that environment. It is noteworthy that the flow pattern is affected by the geometry and the shape of the environment as well as the type of existing affects in area. The area under the study in this thesis is located in Bushehr Gulf and the access channels (inner and outer). The study utilizes the hydrodynamic modeling with unstructured triangular and non-overlapping grids, using the finite volume, From method analysis in two scale sizes: large scale (200 m to 7.5km) and small scale (50m to 7.5km) in two different time durations of 15 days and 3.5 days to obtain the flow patterns. The 2D governing equations used in the model are the Depth-Averaged Shallow Water Equations. Turbulence Modeling is required to calculate the Eddy Viscosity Coefficient using the Smagorinsky Model with coefficient of 0.3. In addition to the flow modeling in two different scales and the use of the data of 3.5 day tidal current modeling have been considered to study the effects of the sediments equilibrium in the area and the channels. This model is capable of covering the area which is being settled and eroded and to identify the effects of tidal current of these processes. The required data of the above mentioned models such as current and sediments data have been obtained by the measurements in Bushehr Gulf and the access channels which was one of the PSO's (Port and Shipping Organization) project-titled, "The Sedimentation Modeling in Bushehr Port" in 1379. Hydrographic data have been obtained from Admiralty maps (2003) and Cartography Organization (1378, 1379). The results of the modeling includes: cross shore currents in northern and north western coasts of Bushehr Gulf during the neap tide and also the same current in northern and north eastern coasts of the Gulf during the spring tide. These currents wash and carry fine particles (silt, clay, and mud) from the coastal bed of which are generally made of mud and clay with some silts. In this regard, the role of sediments in the islands of this area and the islands made of depot of dredged sediments should not be ignored. The result of using 3.5 day modeling is that the cross channels currents leads to settlement places in inner and outer channels in tidal period. In neap tide the current enters the channel from upside bend of the two channels and outer channel. Then it crosses the channel oblique in some places of the outer channel. Also the oblique currents or even almost perpendicular current from up slope of inner channel between No. 15 and No. 18 buoys interact between the parallel currents in the channel and made secondary oblique currents which exit as a down-slope current in the channel and causes deposit of sediments as well as settling the suspended sediments carried by these currents. In addition in outer channel the speed of parallel currents in the bend of the channel which is naturally deeper increases. Therefore, it leads to erosion and suspension of sediments in this area. The speed of suspended sediments carried by this current which is parallel to the channel axis decreases when they pass through the shallower part of the channel where it is in the buoys No.7 and 8 to 5 and 6 are located. Therefore, the suspended sediment settles and because of this process these places will be even shallower. Furthermore, the passing of oblique upstream leads to settlement of the sediments in the up-slope and has an additional effect on the process of decreasing the depth of these locations. On the contrary, in the down-slope channel, as the results of sediments and current modeling indicates the speed of current increases and the currents make the particles of down-slope channel suspended and be carried away. Thus, in a vast area of downstream of both channels, the sediments have settled. At the end of the neap tide, the process along with circulations in this area produces eddies which causes sedimentation in the area. During spring some parts of this active location for sedimentation will enter both channels in a reverse process. The above mentioned processes and the places of sedimentation and erosion in inner and outer channels are validated by the sediments equilibrium modeling. This model will be able to estimate the suspended, bed load and the boundary layer thickness in each point of both channels and in the modeled area.

Antecedentes: Las dificultades alimentarias son problemas de los niños para comer con efectos en su crecimiento y desarrollo. La prevalencia de dificultades alimentarias está entre 25-45% en niños con desarrollo normal y hasta 80% en niños con retraso del desarrollo. La conducta alimentaria del niño depende de las prácticas del cuidador. Objetivo: Determinar la relación entre dificultades alimentarias de niños de 2 a 4 años de dos Centros de Desarrollo Infantil Privados Urbanos de Cuenca y los factores de riesgo: estrategias del cuidador para la alimentación de los niños y niñas, el tipo y nivel de instrucción del cuidador. Método: Estudio cuantitativo transversal realizado en 228 niños de 2 a 4 años de los Centros de Desarrollo Infantil Urbanos de Cuenca: CEIAP de la Universidad del Azuay y los Angelitos de la FEUE, aplicando a los cuidadores dos cuestionarios CCDA-N1-APS y el FSQ. Resultados: La cuidadora principal es la madre (79,4%), el nivel de instrucción del cuidador fue el superior (51,3%). La prevalencia de dificultades alimentarias fue del 28%. No existe relación estadística entre dificultades alimentarias (p>0,05), y el tipo y nivel de instrucción del cuidador. Las estrategias del cuidador que demostraron relación con dificultades alimentarias y factores de riesgo son: estructura a la hora de comer, permitirle tener juguetes durante comidas, puede elegir la cantidad de alimento que quiere, presionarle a comer mas de lo que debe, permitirle comer y beber durante todo el día (p<0,05); el tener un esquema de alimentación es factor protector. Los datos concuerdan con la literatura. Conclusiones: Es necesario evaluar las estrategias del cuidador para la alimentación y dificultades alimentarias.

Variable Data Printing (VDP) has brought new flexibility and dynamism to the printed page. Each printed instance of a specific class of document can now have different degrees of customized content within the document template. This flexibility comes at a cost. If every printed page is potentially different from all others it must be rasterized separately, which is a time-consuming process. Technologies such as PPML (Personalized Print Markup Language) attempt to address this problem by dividing the bitmapped page into components that can be cached at the raster level, thereby speeding up the generation of page instances. A large number of documents are stored in Page Description Languages at a higher level of abstraction than the bitmapped page. Much of this content could be reused within a VDP environment provided that separable document components can be identified and extracted. These components then need to be individually rasterisable so that each high-level component can be related to its low-level (bitmap) equivalent. Unfortunately, the unstructured nature of most Page Description Languages makes it difficult to extract content easily. This paper outlines the problems encountered in extracting component-based content from existing page description formats, such as PostScript, PDF and SVG, and how the differences between the formats affects the ease with which content can be extracted. The techniques are illustrated with reference to a tool called COG Extractor, which extracts content from PDF and SVG and prepares it for reuse.

Une caractéristique intéressante de la protéine Bcl-xL est la présence d'un domaine en boucle non-structurée entre les hélices α1 and α2 de la protéine. Ce domaine protéique n'est pas essentiel pour sa fonction anti-apoptotique et absent chez CED-9, la protéine orthologue chez Caenorhabditis elegans. A l'intérieur de ce domaine, Bcl-xL subit une phosphorylation et déphosphorylation dynamique sur les résidus Ser49 et Ser62 en phase G2 du cycle cellulaire et lors de la mitose. Lorsque ces résidus sont mutés et les protéines exprimées dans des cellules cancéreuses, les cellules démontrent plusieurs défauts mitotiques liés à l'instabilité chromosomique. Pour analyser les effets de Bcl-xL Ser49 et Ser62 dans les cellules normales, les présentes études ont été réalisées dans des cellules diploïdes humaines normales, et in vivo chez Caenorhabditis elegans. Dans une première étude, nous avons utilisé la lignée cellulaire de cellules fibroblastiques diploïdes humaines normales BJ, exprimant Bcl-xL (type sauvage), (S49A), (S49D), (S62A), (S62D) et les double (S49/62A) et (S49/62D) mutants. Les cellules exprimant les mutants de phosphorylation ont montré des cinétiques de doublement de la population cellulaire réduites. Ces effets sur la cinétique de doublement de la population cellulaire corrèle avec l'apparition de la sénescence cellulaire, sans impact sur les taux de mort cellulaire. Ces cellules sénescentes affichent des phénotypes typiques de sénescence associés notamment à haut niveau de l'activité β-galactosidase associée à la sénescence, la sécrétion d' interleukine-6, l'activation de p53 et de p21WAF1/ Cip1, un inhibiteur des complexes kinase cycline-dépendant, ainsi que la formation de foyers de chromatine nucléaire associés à γH2A.X. Les analyses de fluorescence par hybridation in situ et des caryotypes par coloration au Giemsa ont révélé que l'expression des mutants de phosphorylation de Bcl-xL provoquent de l'instabilité chromosomique et l'aneuploïdie. Ces résultats suggèrent que les cycles de phosphorylation et déphosphorylation dynamiques de Bcl-xL Ser49 et Ser62 sont importants dans le maintien de l'intégrité des chromosomes lors de la mitose dans les cellules normales. Dans une deuxième étude, nous avons entrepris des expériences chez Caenorhabditis elegans pour comprendre l'importance des résidus Ser49 et Ser62 de Bcl-xL in vivo. Les vers transgéniques portant les mutations de Bcl-xL (S49A, S62A, S49D, S62D et S49/62A) ont été générés et leurs effets ont été analysés sur les cellules germinales des jeunes vers adultes. Les vers portant les mutations de Bcl-xL ont montré une diminution de ponte et d'éclosion des oeufs, des variations de la longueur de leurs régions mitotiques et des zones de transition, des anomalies chromosomiques à leur stade de diplotène, et une augmentation de l'apoptose des cellules germinales. Certaines de ces souches transgéniques, en particulier les variants Ser/Ala, ont également montré des variations de durée de vie par rapport aux vers témoins. Ces observations in vivo ont confirmé l'importance de Ser49 et Ser62 à l'intérieur du domaine à boucle de Bcl-xL pour le maintien de la stabilité chromosomique. Ces études auront une incidence sur les futures stratégies visant à développer et à identifier des composés qui pourraient cibler non seulement le domaine anti-apoptotique de la protéine Bcl-xL, mais aussi son domaine mitotique pour la thérapie du cancer.
