The performance of the virtual switch Open vSwitch (OVS) is insufficient to satisfy the current requirements for link bandwidth of the server connections. There is an effort to accelerate the OVS both in the software and in the hardware by offloading the datapath to the smart network interface cards. In this work the COMBO card for 100G Ethernet developed by CESNET is used to accelerate the OVS. The suggested solution utilizes the firmware for FPGA generated from the definition in the P4 language to classify the packets in the card and DPDK for the data transfers and offloading the classification rules into the card. Forwarding of one flow with the shortest frames from physical to physical interface using one CPU core reaches forwarding rate of 11.2 Mp/s (10 times more than the standard OVS) with classification in the card and 5.9 Mp/s without classification in the card.

Full textAbstract:
One recent innovation in the networking industry, is the concept of Network FunctionVirtualization (NFV). NFV is based on a networking paradigm in which network functions,which have typically been implemented in the form of dedicated hardware appliances in thepast, are implemented in software and deployed on commodity hardware using modernvirtualization techniques. While the most common approach is to place each virtual networkfunction in a virtual machine - using hardware-level virtualization – the growing influenceand popularity of Docker and other container-based solutions has naturally led to the idea ofcontainerized deployments. This is a promising concept, as containers (or operating systemlevel virtualization) can offer a flexible and lightweight alternative to hardware-levelvirtualization, with the ability to use the resources of the host directly. The main problem withthis concept, is the fact that the default behavior of Docker and similar technologies is to relyon the networking stack of the host, which typically isn’t performant enough to handle theperformance requirements associated with NFV. In this dissertation, an attempt is made toevaluate the feasibility of using userspace networking to accelerate the network performanceof Docker containers, bypassing the standard Linux networking stack by moving the packetprocessing into userspace.

Full textAbstract:
Virtualization is the key technology which has provided smarter and easier ways for effectively utilizing resources provided by the hypervisor. Virtualization allows multiple operative systems (OS) to run on a single hardware. The resources from a hardware are allocated to virtual machines (VM) by hypervisor. It is important to know how the performance of virtual switches used in hypervisor for network communication affect the network traffic. Performance of Linux Bridge (LB) and Open vSwitch (OVS) is investigated in this study. The method that has been used in this research is experimentation. Two different scenarios are used to benchmark the performance of LB and OVS in virtual and non-virtual environment. Performance metrics bitrate is used to benchmark the performance LB and OVS. The results received from the experimental runs contains the ingress bitrate and egress bitrate of LB and OVS in virtual and non-virtual environment. The results also contain the ingress and egress bitrate values from scenarios with different memory and CPU cores in virtual environment. Results achieved in this thesis report are from multiple experiment configurations. From results it can concluded that LB and OVS have almost same performance in non-virtual environment. There are small differences in ingress and egress of both virtual switches.

Ghinda, Elena. "Intonation Structure And Intonation In Svo And Ovs Sentences In Spoken Russian." Master's thesis, METU, 2010. http://etd.lib.metu.edu.tr/upload/12611423/index.pdf.
Full textAbstract:
The purpose of this thesis is to examine the difference between SVO and OVS sentences in spoken Russian, which is a language with flexible word order although the basic order is SVO. Two experiments were conducted to understand the nature of intonation. Experiment 1 shows that the Subject appears as kontrast in OVS
sentences, and as background in SVO sentences. The F0 curve rises in the Object position when the Subject is kontrast in OVS sentences.
The analysis of the results of Experiment 2 shows that the initial element of the sentence plays an important role in intonation. When it is kontrasted, it always has higher (Hz) frequency pitch accent than the final element. There is no difference
between SVO and OVS sentences in this respect because the initial element has high pitch accent, whether it is the Subject or the Object. The verb has no pitch accent and it has a flat intonation regardless of the WO of the sentence (SVO, OVS).

Negli ultimi anni, Kubernetes è emerso come l’orchestratore di applicazioni a containers dominante. Il suo design è basato su un’API che permette di descrivere in modo dichiarativo lo stato desiderato delle applicazioni e su un piano di controllo che lavora per far convergere lo stato effettivo delle applicazioni verso lo stato desiderato, ottenendo fault-tolerance, self-healing ed elevata scalabilità. Questo design pattern si è dimostrato estremamente efficace per la gestione dei container, ma è abbastanza generale da poter essere usato per orchestrare con successo qualsiasi tipo di risorsa virtuale che viene tradizionalmente offerta mediante il paradigma del cloud IaaS. Abbiamo testato questa idea estendendo Kubernetes per fargli gestire, oltre alle usuali applicazioni a containers, delle reti virtuali. Così facendo abbiamo di fatto realizzato il prototipo di un piano di controllo di una SoftwareDefined Network. Nel fare ciò sono emersi sia punti di forza che debolezze del design pattern di Kubernetes e delle librerie open source che lo supportano. Per verificare che il sistema ottenuto abbia una scalabilità adeguata a quella necessaria nei moderni cloud data centers, abbiamo condotto uno studio di performance.

Mestrado em Biotecnologia AlimentarO desenvolvimento de novos produtos é atualmente uma forte aposta das empresas na busca de envolver novos eixos e nichos de mercado, através da inovação, capaz de promover produtos adequados às necessidades mais eminentes do mercado alvo. O projeto em questão, teve lugar no seio do Grupo Derovo, com o objetivo fundamental de desenvolvimento de um ovoproduto líquido pasteurizado à base de gema de ovo (ingrediente crucial e maioritário) específico para a produção de fios de ovos, cuja adequação pode ser em produtos profissionais industriais, bem como para um consumidor doméstico, pautando-se por ser um produto de fácil utilização e capaz de produzir um resultado de alta qualidade. Tratando-se de um projeto ligado ao desenvolvimento de um novo produto alimentar, este processo contemplou diversas etapas, entre as quais se destacam essencialmente: perceção/compreensão das necessidades inerentes ao mercado; ensaios preliminares; testes de formulação de protótipos e avaliação da sua performance; análise de mercado de protótipos selecionados. Numa primeira fase, realizaram-se alguns ensaios preliminares com o intuito de perceber qual o efeito de diversas etapas do ciclo produtivo da unidade produtiva em questão, acompanhados pela análise de parâmetros físico-químicos (pH; Teor de Sólidos Solúveis (°Brix); Viscosidade (mPa.s); Extrato Seco (%)) e da análise fotográfica. Demonstrou-se efetivamente que a gema de ovo não pasteurizada apresentou resultados notoriamente superiores aos conseguidos com as restantes tipologias estudadas. Após uma procura de agentes tecnológicas no mercado de ingredientes alimentares, iniciou-se a fase de formulação de diversos protótipos, por adição de diversas percentagens (0,1 a 0,03%) e combinações (agentes emulsionantes e/ou agentes texturizantes) tendo posteriormente realizado as análises físico-químicas já referenciadas (incluindo ainda Atividade da água e cor). Seguiu-se a avaliação dos protótipos em desenvolvimento na produção de fios de ovos, através de um controlo de diversos fatores inerentes à sua produção (temperatura da calda de açúcar, entre outros), tendo os resultados finais sido alvo de uma análise fotográfica, análise sensorial (provas de medição do grau de satisfação) e análise microbiológica, com o objetivo de comparar os diversos ensaios e auxiliar na selecção dos protótipos em estudo. Demonstrou-se que a percentagem de 0,03% teve a melhor performance na produção de um fio de ovo com características adequadas, principalmente por aplicação de dois agentes tecnológicos específicos (Jungbunzlauer e DynaVisc), estando igualmente adequada à qualidade exigida pelo mercado.
Development of new food products is currently a strong focus of the companies involved in the search for new ways and niche markets through innovation to promote adequate products to the most eminent needs of our market. This project, developed at the Group Derovo, had as its main objective the development of new egg product mainly constituted by pasteurized liquid egg yolk (crucial and major ingredient) specific for the production of traditional portuguese sweet – “fios de ovos” - to both professionals industrials, and also the household consumer, guided for being a product easy to use and capable of producing a high quality product. Since this is a project linked to the development of a new food product, this process included several steps, among which are important to highlight: understanding of the needs inherent in the market; preliminary tests; formulation testing of prototypes and their evaluation performance; market analysis of selected prototypes. Initially, there were some preliminary tests in order to see what effect various stages of the production cycle of egg production unit in question, followed by analysis of physico-chemical parameters (pH, Total Soluble Solids (°Brix), Viscosity (mPa.s), Dry Matter (%)) and photographic analysis. It was shown that effectively unpasteurized egg yolk was notably greater to the results achieved with other types studied. After a demand on the market of technological agents of food ingredients, several prototypes were formulated by addition of various percentages (0,1 to 0,03%) and combinations (emulsifying agents and/or texturizing agents) and subsequently analyzed from the standpoint of the physicochemical analyses already mentioned (further including Water Activity and color) and the microbiological point of view. This was followed by evaluation of the prototype under development in the production of traditional portuguese sweet – “fios de ovos” - by controlling several factors inherent in their production (temperature sugar syrup, etc.), and the final result was the target of a photographic analysis, sensory analysis (tests measuring the degree of satisfaction) and microbiological analysis in order to compare the different assays as well as aid in the selection of the prototypes in this study. It was demonstrated that the proportion of 0.03% had the better performance in the production of traditional portuguese sweet with suitable characteristics mainly by application of two specific technological agents (Jungbunzlauer e DynaVisc) and is also according to the evaluation made by the market.

Orientador: Edivaldo Antônio GarciaResumo: Este experimento teve como objetivo definir o diâmetro de sonda mais adequado para realizar a resistência da casca à quebra, por meio de texturômetro; e ainda determinar qual o melhor posicionamento dos ovos para efetuar esta avaliação e identificar qual método de avaliação da qualidade da casca dos ovos é mais confiável caso não seja possível a avaliação em um aparelho eletrônico. Foi realizado um experimento que levou em consideração o diâmetro da sonda do texturômetro (2, 10 e 75mm), os tipos de ovos (brancos e vermelhos) e posicionamento dos ovos (horizontal e vertical) para avaliação da qualidade da casca. Para tanto, foram utilizados ovos provenientes de poedeiras com 60 semanas de idade, que foram separados por gravidade específica, utilizando-se o método de flutuação em solução salina com densidades variando de 1,070 a 1,100 g/cm3 com intervalos de 0,005 g/cm3, que posteriormente foram pesados em balança de precisão e submetidos à quebra com as sondas de diferentes diâmetros e realizadas as demais avaliações. Foi realizada análise de variância em delineamento inteiramente casualizado, e as médias comparadas pelo teste de Tukey (P<0,05). As correlações entre características foram calculadas pelo método de Pearson. A partir dos resultados obtidos neste estudo, é possível concluir que a sonda mais indicada para a realização da análise de resistência da casca à quebra é a de diâmetro de 75 mm, independente do posicionamento e tipo de ovo.

O ovo é importante como alimento e matéria-prima industrial. O ovo é rico em colesterol que, por sua vez, está sujeito à oxidação, formando-se óxidos tóxicos. O presente trabalho teve como objetivos, a avaliação da formação do 7-cetocolesterol livre em ovo integral em pó e em macarrão contendo ovos, e a verificação da estabilidade oxidativa do colesterol, em ovo integral em pó, durante a estocagem, e em macarrão contendo ovos, em função do cozimento que antecede o consumo. Para tais propósitos foram analisadas cinco marcas de ovo integral em pó, adquiridas de indústrias produtoras e/ou fornecedores, estando dentro do prazo de validade (6 meses). Para a avaliação da estabilidade oxidativa do colesterol em ovo integral em pó, foi selecionada uma das cinco marcas analisadas, em três lotes, com 7 a 15 dias de fabricação, e estocada à temperatura ambiente por 224 dias. Onze marcas de macarrão contendo ovos foram obtidas comercialmente, estando dentro do prazo de validade (2 anos) e analisadas, sendo duas delas selecionadas para a avaliação da estabilidade oxidativa do colesterol em função do cozimento. A metodologia para a determinação do 7-cetocolesterol livre consistiu na extração dos Iípides totais, separação em coluna de Florisil, e a determinação por High-Perforrnance Liquid Chromatography (HPLC). Os resultados de 7-cetocolesterol em ovo integral em pó variaram de 63,74 a 112,80µg/g de Iípides; em macarrão contendo ovos, de 30,49 a 157,25µg/g de Iípides. O emprego do 7-cetocolesterol livre não permitiu indicar com clareza a oxidação do colesterol em ovo integral em pó durante a estocagem. Uma correlação estatisticamente significativa (r = 0,8093) foi verificada entre os resultados encontrados para o 7-cetocolesterol livre e as substâncias que reagem ao ácido tiobarbitúrico - TBARS-, durante a estocagem. O colesterol do macarrão contendo ovos aparentemente foi afetado oxidativamente em função do tratamento térmico, (estatisticamente não-significativos), sugerindo estudos adicionais para melhor avaliar a estabilidade do colesterol nestas condições.Egg is important as food and industrial raw material. It is rich in cholesterol, which, in turn, is subjected to oxidation. Forming toxic oxides. The present work had as objectives the evaluation of the formation of the free 7-ketocholesterol in whole egg powder and in pasta containing eggs, and the verification of the oxidative stability of cholesterol in whole egg powder during the storage, and in pasta containing eggs as a function of pre-consumption cooking. For such purposes, sample of five brands of whole egg powder within their validity period (6 months) donated by industries and/or suppliers and analyzed. For the evaluation of oxidative stability of cholesterol in whole egg powder, one of the tive analyzed brands was split into three lots within 7-15 days from manufacture and stored at room temperature for 224 days. Samples of eleven brands of pasta produced with eggs within their validity period (2 years) purchased at the local commerce and analyzed. Two brands out of the eleven were selected and evaluated concerning cholesterol oxidative stability after cooking. The method for the determination of free 7-ketocholesterol consisted of total Iipid extraction, separation through Florisil column and determination for High-Performance Liquid Chromatography (HPLC). The results of free 7-ketocholesterol ranged from 63.74 to 112.80µg/g of lipids in whole egg powder and from 30.49 to 157.25µg/g of lipids in pasta produced with eggs. The use of free 7-ketocholesterol did not permit to clearly indicate cholesterol oxidation in whole egg powder during storage. The statistically signiticant correlation (r = 0.8093) between the results for free 7-ketocholesterol and the substances that react with thiobarbituric acid - TBARS - during storage was observed. In pasta produced with eggs, cholesterol apparently was oxidized after thermal treatment, (not statistically significant), thus suggesting further studies to bette evaluate cholesterol stability under these conditions.

Mitt i den urbana miljön i Henriksdal, intill Hammarby Sjöstad, bildar den stora innergården en grön oas för elever från förskoleklass till sjätte klass. Skolbyggnaden är sluten från omgivningen för att skydda mot intensivt vägbuller från Värmdövägen, men glasad inåt för att möjliggöra odling i ett tempererat klimat. Växtligheten i odlingskorridorerna ska ge både en lugn miljö med frisk luft och en tidig förståelse för hur naturen fungerar. På taket finns biodlingar och solpaneler för både el och varmvatten. Odlingskorridorerna, utformade som slingrande ramper, sammanlänkar våningsplanen med varandra samtidigt som de ger ytor både för lek och vilsamma pauser. Här får man möjlighet att experimentera och studera växterna på nära håll. Skolans utformning ger en ständig kontakt med årstidernas skiftningar: Stora träd på innergården filtrerar ljuset under de varma månaderna men släpper in ljuset under vintern. Den höga delen av byggnaden skärmar av den värsta trafiken och den lägre delen släpper in ljuset från söder.In the heart of the urban environment in Henriksdal, next to Hammarby Sjöstad, the large inner courtyard forms a green oasis for the students. The school building is closed from the surrounding area to protect against intense road noise, but have glass facades inwards to allow for cultivation in a temperate climate. The vegetation in the Cultivation Corridors should provide both a calm environment with fresh air and an early understanding of how nature works. On the roof, there are beekeeping and solar panels for both electricity and hot water. The Cultivation Corridors, designed as winding ramps, connect the floor plan with each other while providing surfaces for play as well as restful breaks. The school's design provides constant contact with the shifts of the seasons: Large trees in the courtyard filter the light during the warm months but emit light during the winter. The tall part of the building is protecting from the worst traffic and the lower part emits the sunlight from the south.

Syftet med vårt examensarbete är att undersöka vilken geografisk omvärldsbild elever har, dvs. vilken inre karta de har av världen, och hur den formas. Vi har använt oss av en metod bestående av en enkät med både allmänna frågor om elevens erfarenheter samt tre kunskapsbaserade uppgifter om kartan. Den första av dessa tre är en öppen uppgift där eleven ombeds rita världskartan på ett blankt papper. Det görs sedan kopplingar mellan elevernas erfarenheter, kunskaper och den mentala kartan. I resultatet såg vi att eleverna har brister i sin geografiska omvärldsbild och kunskaper om var olika platser ligger i Sverige och världen. Tidigare forskning i ämnet visar att många av våra hypoteser och slutsatser kan bekräftas. Till exempel hade eleverna en geocentrisk och etnocentrisk världsbild. Det märktes tydligt att eleverna formade sin geografiska omvärldsbild utifrån tidigare erfarenheter och attityder till olika platser. Eleverna i vår undersökning har en begränsad geografisk omvärldsbild och behöver därför arbeta mer med att utveckla den.

O presente trabalho teve o objetivo de verificar a influência da inoculação de ingredientes intra ovo aos 18 dias de incubação de ovos oriundos de matrizes jovens e de pesos distintos. Ovos oriundos de matrizes com 30 semanas de idade foram separados em ovos leves e pesados, sendo incubados na mesma máquina incubadora. Aos 18 dias de incubação, no momento da transferência para o nascedouro, os ovos foram inoculados com soluções de Maltose, Polivitamínico, Zinco-Glicina, Glutamina, Mistura de todos os produtos descritos anteriormente e Cloreto de Sódio (controle). Como via de inoculação, as soluções foram utilizadas como diluentes da vacina de Marek efetuada intra-ovo aos 18 dias de incubação. Após o nascimento, 2460 pintinhos machos foram enviados para o aviário experimental onde foram divididos em 60 boxes em um delineamento inteiramente casualizado em esquema fatorial 2x6 (2 pesos e 6 soluções) totalizando 12 tratamentos com 5 repetições de 40 aves. Foram sacrificadas uma ave por repetição aos 00, 07 e 21 dias de idade para pesagem do saco da gema, intestino e fígado. Amostras de duodeno, jejuno e íleo foram enviadas para histologia para determinação de profundidade de criptas e altura de vilosidades. Amostras de sangue foram coletadas e enviadas para laboratório para determinação de nível de anticorpos contra reovírus e bronquite aviária. Os animais e a ração fornecida foram pesados semanalmente (07, 14, 21, 28, 35 e 42 dias) para determinação do peso, consumo e conversão alimentar. Aos 43 dias de idade 3 aves por repetição foram pesadas e sacrificadas para determinação do peso e rendimento de carcaça, peito com osso e pele e perna com osso e pele. Animais oriundos de ovos mais pesados obtiveram uma maior eclosão, peso ao nascimento e peso de fígado e intestino aos 00 dias. O peso aos 42 dias foi superior em aves oriundas de ovos pesados, produzindo uma carcaça e peito mais pesado, porém sem diferença de rendimento. Não houve diferença de conversão aos 42 dias de idade. Viabilidade de animais oriundos de ovos pesados foi superior de 00 a 07, 14 a 21 e 21 a 28 dias de idade, mas não afetou a viabilidade final. Peso do ovo não interferiu com o nível de anticorpos. As inoculações de soluções aos 18 dias de incubação obtiveram resultados variáveis dependendo do produto utilizado, tendo maior influência sobre altura de vilosidades e profundidade de criptas e sobre a produção de anticorpos. Não afetaram, entretanto, os parâmetros zootécnicos (ganho de peso, consumo de ração, conversão alimentar e viabilidade). A inoculação de produtos intra-ovo já é uma técnica possível de ser utilizada na avicultura industrial, entretanto, novos estudos devem ser ainda desenvolvidos no intuito de definir o melhor produto ou composto de produtos a ser utilizadoThis trial had the objective to verify the influence of the in-ovo inoculation of ingredients at 18th day of incubation of eggs from different weights. Eggs from a broiler breeder flock with 30 weeks of age were separated in light and heavy eggs and were incubated in the same machine. At the 18th day of incubation, when the eggs were been transferred, they were inoculated with solutions of Maltose, Vitamins, Zinc-Glicine, Glutamine, mixture of all the ingredients and sodium chloride (control). The solutions were inoculated as Marek\'s vaccine diluter. After the eclosion, 2460 male chicks were send to the experimental house were they were divided on 60 boxes at a completely random design and a factorial 2x6 (two egg weigths and six solutions) design, summing 12 treatments with 5 repetitions of 40 chicks. One chick per repetition was sacrificed at 00, 07 and 21 days of age to weigth the yolk sac, intestine and liver. Samples of duodenum, jejunum and ileum were sent to histology to determinate villus high and cripts deep. Blood sample of the same birds were collected and sent to the laboratory to determinate anti body levels against reovirus and avian bronquitis. Animals and feed were weighted every week to determine the animal weight gain, feed consumption and feed conversion. At 43 days of age, 3 birds per repetition were weighted and sacrificed to determinate the carcass, breast and leg weight and yield. Animals from heavy eggs had a higher born weight, eclosion and liver and intestine weight at 00 days. At 42 days of age, birds from heavier eggs had a higher weight producing a heavier carcass and breast, but without yield variation. There was no difference on feed conversion at 42 days. Liveability of birds from heavier eggs were higher form 00 to 07, 14 to 21 and 21 to 28 days of age, but it didn\'t interfere the total livibility. Egg weight didn\'t interfere on the anti body level. The solutions inoculated at 18th day of incubation had variable results depending on the product utilized, influencing the villus height and cripts deep and anti body production. However, the solutions inoculation doesn\'t interfere on zoothecnical parameters as weight gain, feed consumption, feed conversion and livability. The in-ovo inoculation is a technique possible to be used on broiler production, however, new studies have to be done searching from the best product or ingredient to be used

Resumo: Os núcleos das células tróficas proximais de ovário de Chrysomya putoria, nas diferentes fases do desenvolvimento ovariano, foram examinados em preparações submetidas à reação de Feulgen. Tinha-se como objetivo conhecer as alterações cromatínicas/cromossômicas durante o desenvolvimento das células relacionadas ao processo de formação dos ovos. A alteração mais marcante encontrada foi a organização do material cromatínico sob a forma de cromossomos politênicos típicos. Nessa fase são vistas 6 unidades cromossômicas, nas quais, em determinado momento do seu processo de compactação, pode ser visualizado o padrão de bandas e interbandas característico de politênicos de dípteros. Após essa fase, os cromossomos tornam-se mais e mais encurtados, até que, quando todos apresentam praticamente o mesmo comprimento, os filamentos começam a se separar, originando numerosas unidades, de tamanhos diferentes entre elas que, espalham-se por todo o espaço nuclear. A partir daí, até o final do desenvolvimento, o núcleo tem aparência interfásica, apresentando um ponto heterocromático fortemente corado. A porção eucromática do cromossomo X sofre descompactação precoce, em relação aos autossomos e à sua própria porção heterocromática. Se a fêmea adulta estiver sob uma dieta de açúcar e água, os cromossomos politênicos podem permanecer como tal por um período muito mais longo do que quando sob dieta padrão. Através de microespectrofotometria mostrou-se que os núcleos tornam-se altamente endopoliplóides durante a ovogênese, atingindo o valor máximo de 2048 C, resultado de 10 ciclos de duplicação do DNA. Valores menores, a cada fase, foram obtidos nos núcleos distais, mostrando que há assincronia nos ciclos endorreplicativos das diferentes células tróficas do folículo. O volume ocupado pela cromatina corada aumenta cerca de 12 a 15 vezes durante o desenvolvimento. Os valores Feulgen-DNA bem como a área ocupada pelo corpo heterocromático não acompanham, proporcionalmente, o crescimento do restante da cromatina. As células epitelias do folículo mostraram tornarem-se também endopoliplóides, passando por até 4 ciclos de replicação, após o início da vitelogenese
Abstract: The nuclei of proximal nurse cells of the ovary of Chrysomya putoria in the different stages of ovarian development were examined in preparations submitted to the Feulgen reaction. The objective was to follow the chromatin/chromosomal alterations occurring during the development of those cells involved in the process of egg formation. The most marked alteration encountered was the organizatian of the chromatin in the form of typical polytene chromosomes. In this stage 6 chromosomes could be seen, in which, at a specific point in their process of compactation, the pattern of bands and interbands characteristic of dipteran polytene chromosomes, could be seen. After this stage the chromosomes became increasingly shorter until, when all were practically the same length, their constituent filaments began to separate and scatter throughout the nuclear space. From this point on, up to the end of development, the nucleus exhibited an interphasic appearance, presenting one strongly staining heterochromatic body. The euchromatic region of the X chromosome underwent premature decompactation as compared to the autosomes and to its own heterochromatic segment. If the adult female were maintained on a sugar and water diet, the polytene chromosomes would remain as such for a much longer period than when maintained on a standard diet. Microspectrophotometry showed that the nuclei became highly endopolyploidy during oogenesis, attaining a maximum value of 2048 C, resulting from 10 cycles of DNA duplication. At each stage, lower values were found in the distal nuclei, showing the existence of asynchrony in the endoreplicative cycles of the different nurse cells of the follicle. The volume occupied by the stained chromatin increased 12 or 15 times during development. Neither this Feulgen-DNA values nor the area occupied by the heterochromatic body proportionally followed the growth of the rest of the chromatin. The epithelial cells of the follicle also showed endopolyploidization, passing through up to 4 cycles of replication after the start of vitellogenesis

Full textAbstract:
Background: With the first green bond being issued in 2008 as a joint venture between World Bank Organization and the Swedish bank SEB the financial instrument has made an impact on the financial markets. With a high demand for sustainable investments in Sweden partly due to policies a premium for the green bonds is to be expected at least according to theory. The real estate market has adapted to the increased demand for green investments by moving more towards green bonds, and rightfully so as it is one of the largest polluters seen by sector. In result, it is also one of the largest issuers of bonds which creates an excellent opportunity to research the industry as there is plenty of data available. Purpose: This report will examine the premium of green bonds in the Swedish real estate market. Furthermore, it will also examine the effects of Covid-19 and to what extent this pandemic had an impact on green bonds. Method: The thesis examines the Option Adjusted Spread (OAS) of 166 bonds of 9 different companies from the start of 2016 to December 2020 within the Swedish real estate market. Control variables such as Company risk, Market risk and Macroeconomic variables were used in an OLS regression to estimate the premium. The effect of the Covid-19 pandemic was also examined. Conclusion: After analyzing 53 green and 113 conventional bonds no significant results were found on how premium differs between green and conventional bonds. However more general findings were found that suggest bonds become more sought during the Covid-19. It was further found that the green bond market is rapidly growing and may in a few years be in a better position to be examined.

Full textAbstract:
A review of literature thesis includes articles and publications dedicated to the topic of the digestive tract, the issue of measuring the digestibility of horse nutriens, characteristics and nutritional values of the yellow oat (Avena sativa), black oat (Avena strigosa) and hay.
The practical part is devoted to comparing the nutritional values and digestibility of yellow and black oats in the ration using yellow or black with oat hay
The experiment was conducted on six horses borrowed from the Academic riding club in Prague - Suchdol in February 2016. The preparatory period was 5 days, and sampling of faeces took place fifth morning after the morning feeding. Three pairs were created out of the six horses. The first pair formed gelding breed, Czech warmblood, who were housed in the inner box stable. The second pair formed a Haflinger gelding breed housed in an outdoor box. The third pair formed a Hucul gelding breed and welsh cob, housed in an outdoor box. One of the horses from an experimental pair was fed oat hulls and other horse was fed black varieties oats Raven. Rations was the same for both of the horses and both experimental animals also received the same amount of roughage.
Digestibility coefficient was found at the base of the marker method using indicator lignin. The chemical analysis of determination of dry matter and ash, crude fiber (CF), neutral - detergent fiber (NDF), acid - detergent fiber ADF and acid - detergent lignin (ADL), crude fat and calculated using nitrogen-free substances process colors (BNLV) and organic matter (OH) were performed.
Among the experimental pairs there was no statistically significant difference. Therefore, the hypothesis about differences in nutritional and dietetic value of oat and black oat was rejected.

In experiment 1 were used 1800 eggs, 900 from breeders at 8 weeks and 900 with 31 weeks. The eggs were distributed in a randomized block design in a 3x2 factorial arrangement (three incubation temperatures (36.5, 37.5 and 38.5 ° C) and two breeder ages (8 and 31 weeks). The following traits were assessed: quality of hatching eggs, initial and final weight of eggs, hatchability, egg weight loss, incubation time, percentage of quail, quail birth weight, quails score quality, of embryonic mortality and weight of quails at 40 days. Higher values for hatchability (76.4%) were obtained when the eggs of breeders of 31 weeks were incubated at 38.5 °C with incubation time of 396 and 410 hours. In experiment 2, 180 quails were used, half of them from breeders of 8 weeks and the other half from breeders of 31 weeks.

Full textAbstract:
Den här uppsatsen behandlar elevinflytande över skolundervisningen. Alla styrdokument som reglerar den svenska skolan framhåller vikten av ett sådant inflytande, ändå tyder tidigare undersökningar på en allmän brist på elevinflytande på detta område. För att få inblick i elevernas syn på problemet intervjuade jag sex gymnasieelever. Resultatet visar att elevinflytande över undervisningen är en mycket viktig faktor när det gäller att skapa motivation bland elever. Brist på inflytande hämmar inte bara elevernas intresse för ämnet i fråga, det skadar dessutom deras förtroende för lärarna. Ur intervjumaterialet utkristalliserar sig en ideallärare, lyhörd för såväl elevernas åsikter som deras intressen. Eleverna visade dessutom ett starkt förtroende för sina lärares förmåga att leda dem rätt.This essay explores the concept of student influence in class. All governing documents regarding the Swedish school emphasize the importance of student influence, yet previous studies indicate a general lack of it in practice. In order to get an insight into this problem from a student point of view, I interviewed six upper secondary school students. The results suggest that student influence in class is indeed an important factor in creating motivation among students. A lack of influence not only hampers the students’ interest in the subject in question, it also seriously impedes their reliance in their teachers. An ideal teacher, keenly alive to the opinions as well as to the interests of the students, crystallized from the interviews. The students also displayed a conspicuous trust in their teachers’ ability to guide them the right way.

I denna vetenskapliga uppsats kommer boken En man som heter Ove och filmen En man som heter Ove jämföras med varandra, med fokus på Oves tillbakablickar. Detta görs genom att analysera bokens och filmens tillbakablickar som förklarar Oves förflutna. Filmens tillbakablickar visas via flashbacks. Syftet med denna uppsats är att se hur stor påverkan skillnaden mellan bokens tillbakablickar och filmens användande av flashbacks har på karaktären Ove. Oves resa placeras i Craig Battys modell av protagonistens resa, både i bok och film. De båda resorna jämförs med fokus på Oves bakgrundsberättelse och hur det påverkar Oves karaktär i nutid. Vidare analyseras filmens val av flashbacks med hjälp av Linda Aronsons teori om flashbacks användning och funktion. Analysens resultat visar att Oves bakgrund har stor betydelse för hur Ove agerar i nutid vilket leder till att Ove upplevs olika i de olika medierna.

O ovo é importante como alimento e como matéria-prima industrial. Tem alto conteúdo de colesterol, o qual, por sua vez, está sujeito à oxidação. Os óxidos formados interferem na morfologia e função da membrana celular, inibem a biossíntese do colesterol, e são aterogênicos, citotóxicos, mutagênicos e cancerígenos. O processamento e o armazenamento levam à oxidação do colesterol. O presente trabalho teve como objetivos (a) a caracterização e avaliação do ovo líquido integral (OLI) em relação ao armazenamento da matéria-prima; (b) a avaliação do ovo líquido integral (OLI), do ovo líquido integral pasteurizado (OLIP), do ovo integral em pó atomizado (OIPA) e do ovo integral em pó atomizado armazenado, em relação à estabilidade oxidativa do colesterol; e (c) a avaliação do efeito da adição de antioxidantes naturais durante o processamento do ovo integral em pó atomizado, em relação à estabilidade oxidativa do colesterol. O OLI produzido a partir de matéria-prima armazenada por 30 dias, a 4ºC, não foi afetado quanto à estabilidade oxidativa do colesterol. A pasteurização e a atomização, realizadas em condições de laboratório, não levaram ao comprometimento oxidativo do colesterol. Foi constatada oxidação significativa do colesterol no OIPA, obtido em condições de laboratório, quando armazenado por 90 dias, a 25ºC, na ausência de luz. Os antioxidantes naturais comerciais GUARDIAN® Rosemary Extract (RE) e o GUARDIANTM TOCO 70 (TOCO 70) não foram efetivos na prevenção da oxidação induzida do colesterol, quando adicionados (antes ou depois da atomização) ao ovo integral em pó atomizado obtido em condições de laboratório, armazenado por 21 dias, a 25°C, na ausência de luz.Egg is important as food and as industrial raw material. It has high cholesterol, which, in turn, is subject to oxidation. Cholesterol oxides interfere with morphology and function of cell membrane, inhibit cholesterol biosynthesis, and are atherogenic, cytotoxic, mutagenic and carcinogenic. Processing and storage lead to oxidation of cholesterol. Present study aimed (a) characterization and evaluation of liquid whole egg (OLI) in relation to storage of raw material; (b) evaluation of liquid whole egg (OLI), liquid pasteurized whole egg (OLIP), atomized powder whole egg (OIPA) and stored atomized powder whole egg, relative to cholesterol oxidative stability, and (c) evaluation of natural antioxidants addition\'s effect in processing of atomized powder whole egg, relative to cholesterol oxidative stability. OLI produced from raw materials stored for 30 days, at 4°C, was not affected on cholesterol oxidative stability. Pasteurization and atomization, performed under laboratory conditions, did not lead to significant cholesterol oxidation. It has been found significant cholesterol oxidation in OIPA, obtained under laboratory conditions, when stored for 90 days at 25°C in absence of light. Commercial natural antioxidants GUARDIAN® Rosemary Extract (RE) and GUARDIANTMTOCO 70 (TOCO 70) were not effective in prevention of cholesterol induced oxidation when added (before or after spraying) to atomized powder whole egg obtained under laboratory conditions, stored for 21 days at 25°C in absence of light.

Resumo: Foram determinados pelo método colorimétrico de Bohac et_ al. (1988) os teores de colesterol em carnes de frango, suína e bovina Os valores obtidos para frango cru foram, em média, 58 ± 10, 80 ± 9 e 104 ± 5 mg/100g para carne branca, escura e pele, respectivamente Em frango assado os teores foram 75 ± 17, 124 ± 20 e 139 ± 37 mg/100g para carne branca, escura e pele, respectivamente. As concentrações de colesterol em diferentes cortes de carne suína crua foram em média respectivamente de 49 ± 5, 49 ± 7, 50 ± 6 e 54 ± 6 mg/100g para bisteca, lombinho, pernil e toucinho. Os valores correspondentes para a carne suína cozida foram 97 ± 6, 69 + 12, 82 ± 8 e 56 ± 6 mg/100g, respectivamente Para a carne bovina crua, os teores foram em média 51 ±6, 56 ± 6, 50 ± 4, 52 ± 4 e 51 ± 6 mg/100g para contrafilé, coxão duro, coxão mole, músculo e peito, respectivamente Para contrafilé e músculo cozido foram encontrados os valores de 66 ± 6 e 67 ± 4 mg/100g, respectivamente As perdas por cozimento, calculadas em base seca, foram muito pequenas e em alguns casos desprezíveis. O teor médio de colesterol obtido para ovo foi 190 ± 19 mg/ovo ou 10 ± 1 mg/g de gema pelo método por CLAE . O método colorimétrico recomendado pelo Instituto Adolfo Lutz (IAL.) superestimou os valores (311 ± 16 mg/ovo ou 17 ± 1 mg/g de gema), enquanto que o de Bohac et al, deu resultados (204 ± 18 mg/ovo ou 11 ± 1 mg/g de gema) sem diferença significativa com o de CLAE. Avaliando o uso do teor de colesterol como índice da quanti¬dade de ovo em massas, os métodos colorimétricos (IAL e Bohac et al.) superestimaram os teores de colesterol e, consequentemente, a quantidade de ovo adicionada em todas as massas analisadas. Já o método por CLAE revelou que as massas analisadas continham quantidade de ovo abaixo do mínimo exigido pela legislação vigente.
Abstract: Using the colorimetric method of Bohac et al. (1988), the cholesterol concentrations of meat (chicken, pork and beef) were determined. The mean values obtained for raw chicken meat were 58 ± 10, 80 ± 9 and 104 ± 5 mg/100g for white meat, dark meat and skin, respectively In baked chicken the levels were 75 ± 17, 124 ± 20 and 139 ± 37 mg/100g for white meat, dark meat and skin, respectively The cholesterol concentrations in different cuts of raw pork were on the average 49 ±5, 49 ± 7, 50 ± 6 and 54 ± 6 mg/100g for rib chop, tenderloin, ham and belly, respectively The corresponding values for cooked pork were 97 ±6, 69 ± 12, 82 ± 8 and 56+6 mg/100g, respectively. For raw beef, the mean cholesterol levels were 51 ± 6, 56 ± 6, 50 ± 4, 52 ± 4, 51 ± 6 mg/100g for "longissimus dorsi", "biceps femoris", "semimembranosus", shank and breast, respectively. For cooked "longissimus dorsi" and shank, 66 ±6 and 67±4 mg/100g cholesterol, respectively, were encountered. Losses on cooking, calculated on the dry basis, were very small and in some cases negligible. The mean cholesterol concentration for eggs obtained by an HPLC method was 190 ± 19 mg/egg or 10 ± 1 mg/g egg yolk. The colorimetric method recommended by the Instituto Adolfo Lutz (IAL) overestimated the concentrations (311 ± 16 mg/egg or 17 ± 1.0 mg/g egg yolk) while that of Bohac et al. (204 ± 18 mg/egg or 11 ± 1 mg/g egg yolk) gave results with no significant difference with those of the HPLC method. Evaluating the use of the cholesterol level as index of the amount of eggs in egg noodles, the colorimetric methods of IAL and Bohac et al. overestimated the cholesterol concentration and, consequently, the amount of eggs added in all the samples analyzed The HPLC method revealed that the amount of eggs in the egg noodles analyzed was below the minimum required by existing regulation.

Full textAbstract:
The goal of the Master thesis was to construct an obstacle avoidance system. It was the intention that this system can be used as part of a bigger project performed at the lab. The system was implemented and tested for a Pioneer 2DX mobile robot in the lab environment. The positioning of the robot was done with an external ultrasound system provided by the lab. The Digiclops 3D camera from Gray Point research was used for main vision sensor. The code was written in C and implemented in Windows environment. The obstacle avoidance system contains image processing, map building, and control. For control, the Vector Field Histogram theory was studied and implemented. Fixed Decomposition was used to describe the surrounding world. The OAS system was tested for 6 different sets of obstacle environments: a single obstacle, a gate, multiple obstacles, mobile obstacles, a corridor, and a maze. Each set were designed to test the limits of the system. All tests were recorded on video, the position data and the map were saved. In all obstacle sets, the system proved successful. There was no risk for collision and the efficient path planning created a smooth path to the goal.

Resumo: Foi estudada a secagem de albume, gema e ovo integral usando um secador por atomização. Na operação de secagem a atomização foi feita com bocal de pressão e o ar de secagem foi aquecido diretamente pela combustão de gás liquefeito de petróleo. A pressão de atomização das amostras variou de 12 a 13kg/cm² e a temperatura do ar de secagem foi de aproximadamente 200°C. Na secagem de ovo integral líquido foi obtida a relação de 404,5kg/h de ar de secagem para 13,01kg/h de água evaporada. A eficiência térmica calculada foi de 45,20% e as perdas de calor calculadas foram de 17,421. O controle de qualidade das amostras desidratadas de albume, gema e ovo integral, foi feito através de ensaios microbiológicos e da dosagem de proteína solúvel, durante seis meses de armazenamento das amostras na temperatura de 20°C. Os resultados dos ensaios microbiológicos indicaram que não houve crescimento de microrganismos durante o armazenamento das amostras. Os resultados da dosagem de proteína solúvel mostraram que a insolubilização proteica das amostras aumentou com o tempo de armazenamento. Esses resultados ajustaram-se ao modelo cinético de Michaelis-Menten, sendo obtidos os valores de velocidade máxima de insolubilização proteica de 3,26% de insolubilização por mês (PIM) para a gema, 5,26 PIM para o albume e 12,50 PIM para o ovo integral, respectivamente. Os valores da constante de Michaelis-Menten foram 1,71, 4,47 e 9,00 para o albume, gema e ovo integral, respectivamente. Foi também estudada a redução da glicose livre em amostras de ovo integral líquido, pelo método de fermentação, em ensaios de laboratório. Nesses ensaios foi utilizado inoculo de levedura fresca de panificação, nas concentrações de 0,25 a 0,50% em peso no mosto, que foi mantido nas temperaturas de 22, 26, 30 e 32°C. O melhor resultado foi obtido com os ensaios nos quais a concentração de inoculo no mosto foi de 0,50% e a temperatura de fermentação foi mantida em 32°C. Com 120 minutos de fermentação foi conseguida a redução de 88,32% da glicose inicialmente presente nas amostras. Durante a fermentação foi observado o decréscimo do pH do mosto, paralelamente à redução de glicose
Abstract: Drying of albumen, yolk and whole egg was studied, using a spray-dryer. Pressure nozzle was employed for atomization and drying air was directly heated by combustion of liquefied petroleum gas. The atomization pressure of the liquid samples varied between 12 and 13kg/cm² and drying air temperature was about 200°C. A ratio of 404,5kg/h of drying air to 13,01kg/h of evaporated water was obtained for the drying of liquid whole egg. Calculated thermal efficiency and heat loss were 45,20% and 17,42%, respectively. Quality control for albumen, yolk and whole egg dehydrated samples were done by microbiological and soluble protein essays, during six months storage at 20°C. Microbiological results did not show growing of microorganisms during storage. Soluble protein results were indicative that samples protein insolubilization increased during storage time. These results fitted to Michaelis-Menten kinectic model. Maximum velocity values were 3,26% insolubilization by month (PIM) for yolk, 5,26 PIM for albumen and 12,50 PIM for whole egg. Michaelis-Menten constant values were 1,71, 4,37 and 9,00 for the albumen, yolk and whole egg, respectively. Glucose reduction of the liquid whole egg were carried out by fermentation process, in laboratory essays. Brewer's yeast was added to egg melange until concentration of 0,25 and 0,50% by weight, and it was maintained at 22, 26, 30 and 32°C. Better results was obtained with the melange brewer's yeast concentration of 0,50% and 32°C of fermentation temperature. Glucose reduction of 88, 32% was achieved after 120 min of fermentation, during which pH decrease was also observed

Mestrado em Biologia Molecular e CelularFerramentas que armazenem e procedam à catalogação das proteínas identificadas em proteomas resultantes de amostras de tecidos diversos recolhidos a partir de indivíduos representativos de situações fisiológicas e patológicas, constituem instrumentos poderosos para a integração da informação já publicada. Muita informação sobre os mecanismos moleculares subjacentes a patologias pode hoje ser gerada a partir de estratégias bioinformáticas. No âmbito de projetos anteriormente desenvolvidos foi construída uma base de dados, o OralOme. O presente trabalho tem como objetivo a criação de uma base de dados, o OvinOme, aplicando a mesma metodologia desenvolvida para saúde humana, agora para o armazenamento e catalogação de proteínas identificadas a partir dos proteomas parciais de Ovis aries. A criação desta ferramenta bioinformática contribuirá para o desenvolvimento de métodos de diagnóstico em vida, capazes de detetar as principais patologias que grassam nos rebanhos de ovelhas Serra da Estrela. O desenvolvimento da base de dados passa pelo compilar manual das proteínas identificadas pelos vários estudos publicados relativamente a Ovis aries, anotando toda a informação relativa à caracterização do individuo dador da amostra, tipo de amostra biológica, técnicas utilizadas para a identificação das proteínas e toda a informação conhecida relativa a cada proteína catalogada. O desenvolvimento de um método de diagnóstico em vida passa pela concepção de protocolos de colheita, armazenamento e caracterização da qualidade da amostra. Assim no âmbito de presente trabalho foi também objectivo o desenvolvimento de toda a estratégia para recolha de amostras de saliva em ovinos, transporte, armazenamento e avaliação da qualidade da amostra. A criação de um banco de saliva de rebanhos de ovelhas Serra da Estrela será um objectivo a cumprir em termos de futuro, visando o estabelecimento do diagnóstico precoce utilizando a saliva como fluído para avaliação de proteínas que identifiquem cada patologia, determinadas por análise in silico recorrendo á ferramenta bioinformática OvinOme desenvolvida no âmbito do presente trabalho.
Tools that store and proceed to the cataloging of proteins identified in proteomes derived from samples of various tissues collected from individuals representative of physiological and pathological situations, are powerful tools for the integration of information already published. Much information about the molecular mechanisms underlying pathologies can now be generated from bioinformatic strategies. Under previously developed design was built a database, the OralOme. This work aims to create a database, the OvisOme, applying the same methodology developed for human health now for storage and cataloging of proteins identified from the partial proteomes of Ovis aries. The creation of this bioinformatics tool will contribute to the development of diagnostic methods in life, able to detect major diseases that are rife in flocks of sheep Serra da Estrela. The development database is compiled by the proteins identified by several studies published for manual Ovis aries, noting all the information on the individual characteristics of the donor of the sample, type of biological sample, techniques for identifying proteins and whole known information cataloged for each protein. The development of a method of diagnosis in living passes through the design of the harvesting, storage and characterization of the quality of the sample protocols. So within this study was also aimed at developing the whole strategy for collecting samples of saliva in sheep, transport, storage and evaluation of sample quality. The creation of a database of flocks of sheep saliva Serra da Estrela is a key objective for the future, for the establishment of early diagnosis using saliva as a fluid for evaluation of proteins that identify each pathology, determined by in silico analysis using OvisOme bioinformatics tool developed under this work.

The purpose of the thesis is to examine the thoughts and opinions of a selected group of people regarding the terrorist attack that occurred in Stockholm 12/11-2010. This study has been conducted through the method of focus group interview.The study was methodologically and theoretically inspired by Grounded Theory, which simply means that the participants' opinions have formed the theory of the study.As a result of the study, we can see that the main focus of the discussion held by the participants was through a we and them thinking-perspective. Furthermore, the study reveals that the participants tried to include who we (muslims) are, and to exclude who they (non muslims) are, while arguing in the discussion. Another definition is the one of here and there, where the participants defined terrorism and what causes it. Finally, media's role was discussed in relation to the creation of the medie-muslim.To explain the participants' perceptive, part of Appadurai’s Fear of small numbers and part of Brune’s Dark magic in the white media was used.

OPS-SAT is an in-orbit laboratory mission designed to allow experimenters todeploy new on-board software and perform in-orbit demonstrations of new tech-nology and concepts related to mission operations. The NanoSat MO Frame-work facilitates the process of developing experimental on-board software for OPS-SAT by abstracting the complexities related to communication across the space toground link as well as the details of low-level device access. The objective of thisproject is to implement functional simulation models of OPS-SAT peripherals andorbit/attitude behavior, which integrated together with the NanoSat MO Frame-work provide a sufficiently realistic runtime environment for OPS-SAT on-boardsoftware experiment development. Essentially, the simulator exposes communi-cation interfaces for executing commands which affect the payload instrumentsand/or retrieve science data and telemetry. The commands can be run either fromthe MO Framework or manually, from an intuitive GUI which performs syntaxcheck. In this case, the output will be displayed for advanced debugging. The endresult of the thesis work is a virtual machine which has all the tools installed todevelop cutting edge technology space applications.

Full textAbstract:
El Síndrome del Intestino Irritable (IBS) se define como una alteración de la función gastrointestinal caracterizada por dismotilidad e hipersensibilidad visceral. En la mayoría de pacientes con este síndrome el número de mastocitos de mucosa intestinal (IMMC) y su actividad están aumentados. Este hecho podría jugar un papel central en las alteraciones funcionales, sensitivas y motoras del IBS ya que la activación de esta población celular provocaría la liberación de mediadores que podrían afectar a la excitabilidad de las neuronas entéricas y a la de las aferentes primarias, así como a la contractilidad del músculo liso intestinal. No obstante, este síndrome presenta un diagnóstico difícil y un tratamiento poco efectivo ya que los factores que lo causan aún no están claros. Recientemente los procesos alérgicos no diagnosticados hacia componentes de la dieta se han propuesto como posible factor desencadenante del IBS. Se requiere sin embargo disponer de modelos in vivo para estudiar los mecanismos implicados e identificar nuevas dianas terapéuticas. El modelo experimental inducido en rata Sprague Dawley (SD) a la que se expone a ovo-albúmina (OVA) por vía oral reproduce algunos de los hallazgos observados en pacientes con IBS: un aumento de la actividad mastocitaria y una alteración en la motilidad.El objetivo de esta tesis doctoral ha sido contribuir a caracterizar el modelo de exposición oral a OVA en rata SD; determinar el tipo de respuesta inmune inducida por el antígeno, evaluar la actividad mastocitaria y su implicación en la dismotilidad inducida por OVA y valorar la participacion del factor de crecimiento nervioso (NGF) en el proceso.
La exposición oral a OVA, a diferencia de otras proteínas como la gelatina, produjo un aumento en la actividad mastocitaria en el intestino delgado y el colon, como reflejan el aumento del número de IMMC y el incremento de la concentración intestinal de RMCPII. Sin embargo, parámetros como la concentración de IgE o IgG específicas anti-OVA, IL4 o la presencia de eosinófilos y celulas IgE+ en tejido intestinal no se vieron afectados por la exposición a OVA. Estos resultados, junto con el aumento de liberación de histamina tras la estimulación directa de mastocitos con OVA in Vitro, sugirieron que el efecto de esta proteína podría deberse a una interacción directa, no mediada por anticuerpos, entre OVA y el mastocito. La exposición oral a OVA también produjo un incremento en parámetros relacionados con la respuesta motora principalmente en colon, así como en la expresión de NGF en tejido intestinal. Finalmente, el tratamiento con ketotifeno disminuyó significativamente el aumento inducido por OVA sobre la actividad mastocitaria y la respuesta motora y la expresión de NGF. Además se observó una correlación entre el efecto de OVA sobre la actividad mastocitaria y la respuesta motora especialmente en colon, que contribuye a proponer la hipótesis de que los mastocitos están implicados en la alteración de la motilidad intestinal.
La exposición de ratas SD a OVA por vía oral induce una alteración de la motilidad intestinal que no es mediada por una reacción de naturaleza alérgica. A la disfunción motora provocada por la OVA contribuyen sin embargo los mastocitos, probablemente mediante la interacción directa entre esta población celular y la proteína que puede generar, entre otros mediadores, la liberación de NGF. Este mecanismo no alérgico que implica a los mastocitos puede ser relevante en ciertos tipos de pacientes con IBS, cuyo abordaje terapéutico quizás requiera de un replanteamiento. Este trabajo ha apuntado el camino para una caracterización más profunda del modelo con el objetivo de identificar nuevas dianas terapéuticas.
Irritable Bowel Syndrome (IBS) is an alteration of the gastrointestinal function characterised by dismotility and visceral hypersensitivity. In most patients with this syndrome the number of intestinal mucosal mast cells (IMMC) and its activity are increased. This could play a central role in any physiological, sensory and motor IBS because activation of this cell population would result in the release of mediators that could affect the excitability of enteric neurons and primary afferents, as well as the intestinal smooth muscle contractility. However, this syndrome presents a difficult diagnosis and ineffective treatment because the factors that cause it are still unclear. Recently undiagnosed allergic processes to dietary components have been proposed as a possible trigger of IBS. However is required to have in vivo models to study the mechanisms involved and identify new therapeutic targets. The rat experimental model induced in Sprague Dawley (SD) which is exposed to ovo-albumin (OVA) orally play some of the findings in patients with IBS: increased mast cell activity and altered motility.
The aim of this PhD was to characterize the model of oral exposure to OVA in SD rat; determine the type of immune response induced, the mast cell activity and assess their involvement in the OVA-induced dysmotility and evaluate the participation of Nerve growth factor (NGF) in the process.
Oral exposure to OVA, unlike other proteins such as gelatin, induced an increase in mast cell activity in the small intestine and colon, as reflected in the increased number of IMMC and intestinal RMCPII concentration. However, parameters such as concentration of specific IgE or IgG anti-OVA, IL4 or the presence of eosinophils and IgE + cells in intestinal tissue were not affected by exposure to OVA. These findings, coupled with increased histamine release after direct stimulation of mast cells with OVA in vitro, suggested that the effect of this protein could be due to direct interaction between OVA and the mast cell. Oral exposure to OVA also produced an increase in parameters related to motor response mainly in the colon, as well as in the expression of NGF in intestinal tissue. Finally, treatment with ketotifen significantly reduced the OVA-induced increase of mast cell activity and motor response and the expression of NGF. We observed a correlation between the effect of OVA on mast cell activity and motor response especially in the colon, which contributes to hypothesize that mast cells are involved in altering intestinal motility.
Oral exposure to OVA in SD rats induces a disturbance in motor response that is not mediated by an allergic reaction. However, mast cells have a key role in the disturbance of intestinal motility, probably through direct interaction between this cell population and the protein, which can generate, among other mediators, the release of NGF. This nonallergic mechanism involving mast cells may be relevant in certain types of patients with IBS, whose therapeutic approach may require a restatement. This work has pointed the way for a deeper characterization of the model with the aim of identifying new therapeutic targets.

Full textAbstract:
Five strains (9L, 642A, 714, 5688T and 3384Y) of Histophilus ovis were investigated with respect to iron acquisition. All strains used ovine, bovine and goat, but not porcine or human, transferrins (Tfs) as iron sources for growth. In solid phase binding assays, total membranes from only two (9L and 642A) of the five strains, grown under iron-restricted conditions, were able to bind Tfs (ovine, bovine and goat, but not porcine or human). However, when the organisms were grown under iron-restricted conditions in the presence of bovine Tf, total membranes from all strains exhibited Tf binding (as above); competition experiments demonstrated that all three Tfs (ovine, bovine and goat) were bound by the same receptor(s). An affinity isolation procedure allowed the isolation of two putative Tf-binding polypeptides (78 and 66 kDa) from total membranes of strains 9L and 642A grown under iron-restricted conditions, and from membranes of all strains if the growth medium also contained Tf. A gene encoding a Pasteurella multocida TbpA homologue was shown to be present in each of two representative strains (9L and 3384Y); these genes were sequenced and determined to be the structural genes encoding the 78-kDa Tf-binding polypeptides. The identification of a fur homologue and a Fur box within the promoter region of tbpA in both strains indicated that Fur (and iron) is responsible for the iron-repressible nature of Tf-binding activity. Although tbpA transcripts were detected by reverse transcription (RT)-PCR with RNA isolated from strains 9L and 3384Y grown under iron-restricted conditions, with strain 3384Y, and depending on the primer pair, tbpA transcripts were detected by RT-PCR predominantly when the RNA was isolated from cells grown under conditions of iron-restriction in the presence of Tf. The presence of an additional G in the tbpA gene of strain 3384Y grown under iron-replete conditions, compared to organisms grown under iron-restricted conditions plus bovine Tf, is

The Optical System Simulator (OSS) provides a comprehensive platform for the analysis and design of isolated optical devices and entire optical systems, with special focus on semiconductor lasers and system exhibiting fast dynamics. The OSS is able to simulate "1-D" (or fundamental mode) optical devices, such as ideal optical sources, narrow stripe semiconductor lasers, wave-guides, passive cavities, mirrors, beam splitters, etc. These individual elements can be combined to form into complex optical systems. Once the optical system is defined, the user can interact with the simulation interactively using a set of Graphical User Interfaces (GUIs). These provide a visual representation of user-defined sensor outputs, and allow on-the-fly modification of system parameters, in a manner similar to that of an experimental setup. Additionally, the user can use the simulator in a background mode, with no user interfaces required, allowing very long simulations that can run unattended for hours or days. The users may reattach the GUIs at any time to monitor the simulation progress or to modify system parameters. The OSS provides a unique software simulation environment for teaching, research and design of broadband integrated optical and opto-electronic systems, where several Terahertz of optical bandwidth needs to be resolved, from femtoseconds to milliseconds time scales.

Full textAbstract:
Bakgrund: För många personer är döden obehaglig och skrämmande. Palliativ vård ger en helhetsvård till den som diagnostiserats med en dödlig sjukdom. Palliativ vård kan delas in i två olika faser, allmän och specialiserad palliativ fas. Den palliativa sjukdomen delas upp i tidig och sen fas och övergången mellan dessa bestäms vid ett brytpunktssamtal. När döden närmar sig förändras patientens tillstånd och olika symtom uppstår. Som vårdpersonal i den palliativa vården innefattar arbetet inte enbart att vårda patienten utan även att ge vård till de närstående, både under vårdvistelsen men även efter patientens död. Syfte: Att undersöka närståendes upplevelser av palliativ vård. Metod: Kvalitativ litteraturstudie innehållande tio artiklars resultat. Resultat. De närstående önskade att information om familjemedlemmens situation gavs individuellt utformat samt rakt och tydligt. Många närstående önskade närvara och medverka i vården samt hjälpa till med det som de kunde. Närstående upplevde inte alltid att vårdpersonalen tillgodosåg deras behov, men majoriteten upplevde att de kände sig välkomna och väl bemötta. Det var extra betydelsefullt att få närvara vid dödsögonblicket och att vårdpersonalen försedde dem med individuellt anpassat stöd. Konklusion: Information upplevdes lugnande och önskvärt för de närstående att få gällande sin familjemedlems sjukdom. Genom att få hjälpa sin familjemedlem med vardagliga moment känner de närstående sig mindre hjälplösa. Närstående märker, om det leende som vårdpersonalen bär, är äkta och ett bra bemötande får dem att känna sig välkomna.Background: Death is for many people both frightening and painful. Palliative care provides a comprehensive care for the person who has been diagnosed with a deadly disease. The palliative care can be divided into two separate phases, one general phase and one specialized phase. The palliative disease is also divided into two separate parts, the early phase and the latter phase which are decided with a breakpoint conversation. When death is approaching the status of patient changes and various of symptoms arise. The palliative care implies, for the care staff, not only to nourish the patient but also to treat the relatives’, both during the stay at the hospital and after the passing of the dead patient. Objective: To explore the experiences for the relatives of the palliative care. Method: A qualitative literature review containing the result of ten articles. Result: The relatives wished that they were informed about the patient’s status in a concrete and straightforward manner. Many of the relatives wished to be present and to contribute in the course of the care and also to help as far as possible. The relatives’ also felt that the nursing staff did not meet their needs. However, the majority of the relatives felt that they were welcome and treated in a positive way. Furthermore, it is also significant for the relatives to be present in the moment of death and that they were provided with support meet the specific needs on an individual basis. Conclusion: Information regarding the disease of the family member was calming and wishful for the relatives’. By helping their family member, the relatives felt less helpless. Relatives also notice if the smiles of the care staff are genuine and a good treatment makes the relatives feel welcome.

Syftet med mitt examensarbete är att undersöka vilka argument som finns för gymnasieskolans matematikundervisning, samt hur läroplan och kursplaner förhåller sig till dessa argument. Därigenom hoppas jag kunna befästa skolmatematiken som sådan, men även bygga upp en arsenal av argument för att bemöta framtida elevers behov av motivation. För att uppnå detta syfte har jag genomfört en litteraturstudie av olika forskares och matematikdidaktikers texter kring argumenten för skolmatematiken och sedan kategoriserat dessa i fyra argumentskategorier. Därefter har jag försökt utreda argumentens implikationer i skolverksamheten. Resultaten visar att vissa av argumentskategorierna vilar på en ganska osäker grund, medan andra är väl underbyggda. Detta till trots förmår inget argument att ensamt bära skolmatematiken, utan olika delar bärs upp av olika argument.

Relatório de estágio do mestrado em Gestão, apresentado à Faculdade de Economia da Universidade de Coimbra, sob a orientação de Rui Pedro Santos Lourenço e Cristovão Domingues.Nos últimos anos a logística tem-se revelado fundamental para qualquer empresa, na medida em que a falta de um componente, numa linha de produção pode significar a paragem da empresa e por consequência o encerramento temporário, da mesma. Um exemplo disso foi o caso ocorrido durante o período de greve dos camionistas que obrigou certas empresas a pararem a produção, por falta de componentes e matéria-prima. A logística pode ser fragmentada em diversas áreas, tais como a expedição; a recepção; a gestão de armazém, entre outros. A esta logística, normalmente, chama-se logística directa, pois o fluxo vai sempre ao encontro do cliente com o intuito de entregar a mercadoria nas melhores condições, de modo a superar as suas expectativas. Recentemente, as empresas têm enfrentado um novo problema que se prende com as recolhas ou devoluções dos clientes, é chamada logística inversa que não é mais do que a circulação dos bens, no sentido inverso à logística directa. É nesta logística que as empresas manifestam as maiores dificuldades, sendo por vezes o seu custo elevadíssimo. Outra dificuldade consiste em registar a entrada da mercadoria, bem como, saber da sua localização no armazém. Para a realização do presente trabalho procurei fundamentar conceitos relacionados com cadeia de abastecimento, logística, picking, transportes, Warehouse Management Systems (WMS) e tecnologias de Radio-Frequency IDentification (RFID), como componentes de uma estratégia logística, no sentido de optimizar resultados e criar vantagem competitiva. O estágio compreendeu a instalação de um WMS apoiado por um sistema de picking, em que os registos dos produtos passaram a ser feitos de uma forma informatizada, tanto à entrada como à saída. Com o aumento do volume de mercadorias a circular e com o alargamento da gama de produtos que a empresa começou a produzir e a vender, houve necessidade de colocar um sistema que facilitasse a recepção das matérias-primas e a expedição dos produtos. Outra razão que levou a empresa a adoptar um sistema de gestão de armazém foi a necessidade de aumentar a fiabilidade da informação e a eliminação de erros na introdução de dados relativos aos produtos. Acresce-se ainda que a competitividade do mercado faz com que as empresas necessitem de sistemas informáticos, que possibilitem a comunicação entre os parceiros da cadeia de abastecimento. Deste modo, a empresa teve necessidade de instalar um WMS apoiado por um sistema de picking. O presente trabalho pretende mostrar quais poderão ser as mais-valias na implementação de um sistema de gestão de armazém, ao nível da poupança de custos e diminuição das perdas, resultantes da falta de gestão de stocks.

The purpose of this essay is to explore the importance of library design to students, whether the interior design of a library has any effect on their experience when using its services, and what the students themselves believe is most important for the library to do to stay afloat in a society that is constantly evolving and becoming more digital. The study will also bring up UX (User Experience) as a method for library design. The theories used in this study are the third place theory, as well as a comparison to the ideals of the Learning Commons model. In order to find out how the students view the library and the impact of its design, five interviews with five different students at Linneaus University in Växjö were conducted. The results show that the library generally inspires the students to feel motivated and at ease in a place that is comfortable and safe. It also shows that the design and the general atmosphere of the library does play a specific role in the students’ overall experience of the library as it impacts many of the choices they make while they’re there, such as where to sit or which places to avoid. The majority of the students are mostly happy with the library as it is except for minor inconveniences, and merely wishes for the library to continue in the same way in the future while adapting to any new changes that may come in its way.

Os efeitos da adição de biomassa de Rubrivivax gelatinosus em dietas de galinhas poedeiras foram investigados. Sorgo e milho foram utilizados para formulação de rações basais que receberam níveis crescentes de biomassa. A biomassa bacteriana aumentou a tonalidade de vermelho e diminuiu a luminosidade das gemas quando adicionada a ambas as rações basais. Na ração à base de milho, 1.500ppm de biomassa foram suficientes para alcançar a preferência do consumidor, enquanto que, com ração à base de sorgo, 7.500ppm foram necessários para atingir o mesmo objetivo. Galinhas alimentadas com ração à base de milho tiveram consumo de ração superior e melhor conversão alimentar que aquelas alimentadas com ração à base de sorgo, mas os níveis de inclusão da biomassa em ambas as rações basais não influenciaram estes parâmetros. Durante o período experimental não ocorreu mortalidade nem mudança no peso das galinhas. As galinhas alimentadas com ração à base de milho mostraram taxas superiores de produção de ovos, peso e massa de ovos que aquelas alimentadas com ração à base de sorgo. Estes parâmetros não foram influenciados pela inclusão de níveis de biomassa em ambos os tipos de ração. Níveis normais para enzimas séricas e ausência de lesões degenerativas e inflamatórias nos fígados e nos rins das galinhas permitem a indicação da biomassa para suplementação de rações.
The effects of the dietary inclusion of Rvi. gelatinosus biomass in layers rations were investigated. Sorghum and corn were used for the formulation of basal rations that received increasing levels of biomass. The bacterial biomass increased red hues and decreased lightness of yolks when added to both basal rations. Biomass at 1,500ppm in the corn-based ration was enough to reach consumers` preference, while with the sorghum-based ration, 7,500ppm were necessary to reach the same. Hens fed corn-based rations had superior feed consumption and better feed conversion than those fed sorghum-based rations but the inclusion levels of the biomass on both basal rations did not influence these parameters. No mortality and no change on layers weight occurred during the experimental period. Hens fed corn-based rations showed superior egg production, egg weight and egg mass rates than those fed sorghum-based rations. These parameters were not influenced by the inclusion levels of the biomass on both kinds of rations. Normal levels for seric enzymes and the absence of degenerative and inflammatory lesions in livers and kidneys of hens allow the indication of the biomass for ration supplementation.

La rehabilitación implantológica del sector posterior del maxilar superior viene condicionada por la atrofia ósea secundaria a la pérdida de uno o mas dientes y a la consecuente neumatización del seno maxilar, que reducen la disponibilidad ósea para la inserción de implantes dentales. Una de las técnicas mas utilizadas para resolver esta situación es la elevación de seno. Técnica quirúrgica consistente en el abordaje maxilar, la elevación de la membrana sinusal y relleno del espacio creado entre el hueso residual y la membrana. El material de injerto utilizado para el relleno y aumento de la altura ósea en el maxilar ha sido motivo de múltiples estudios y sigue siendo una línea de investigación. Material autólogo, xenoinjerto, aloinjerto o materiales sintéticos se utilizan con diferentes resultados como injertos en el seno maxilar. El objetivo de este proyecto de tesis doctoral es la comparación histólogica e histomorfométrica de dos materiales, Bio-Oss® y Bio-Oss®/Collagen en elevaciones de seno bilaterales y la comparación de los cambios dimensionales logrados con cada uno de los materiales de estudio. Metodología: se realizaron elevaciones de seno con abordaje lateral y de forma bilateral a 18 pacientes. A cada paciente se le realizó dos elevaciones de seno, y se le asignó de forma aleatoria un material de estudio en cada uno de los cuadrantes. Tras un periodo mínimo de 6 meses, en el momento de la inserción de los implantes se tomó una muestra ósea de cada seno injertado para su estudio histológico e histomorfométrico. Resultados: el análisis histomorfométrico demostró una composición histológica similar en los senos regenerados con Bio-Oss® y los regenerados con Bio-Oss®/Collagen, en términos de hueso nuevo formado, partícula residual y tejido conectivo. Ambos materiales resultaron en un aumento de la altura ósea que suficiente para la inserción de implantes. Conclusiones: tras los resultados obtenidos, podemos concluir que los dos materiales estudiados resultan adecuados para ser utilizados en cirugía de elevación de seno, sin que exista diferencias significativas en cuanto a la composición histológica y en cuanto a cambios dimensionales entre uno y otro.

Die Oberflächeneigenschaften eines Festkörpers können mit Hilfe dünner, durch Selbstorganisation gebildeter Molekülschichten aus Alkoxysilan-Molekülen gezielt verändert werden. Mikrostrukturierte selbstangeordnete Monolagen (SAM) können für die Anwendung in Bauelementen aus organischen Halbleitern von großem Interesse sein. Mikrokontaktdruck und Photolithographie sind zwei etablierte Verfahren, die jedoch Vorlagen und Masken zur Strukturierung benötigen. Dadurch entstehen bei häufig wechselnden Strukturen nicht zu vernachlässigende Rüstzeiten und Kosten. In der vorliegenden Arbeit wird die Erzeugung lateral strukturierter Schichten von Octadecyltrichlorsilan (OTS) auf Siliziumoxidoberflächen am konkreten Beispiel zweier alternativer, sowohl maskenloser als auch kontaktloser Methoden demonstriert: (i) Tintenstrahlverfahren als rein additive Strukturierung, und (ii) laserinduzierte, photothermische Desorption als subtraktive Strukturierung einer OTS-SAM . Für das Tintenstrahldruckverfahren wird an einem Kontaktwinkelmessgerät eine Methode zur Beobachtung und Auswertung der Tropfenverdampfung implementiert und ein Modell für kleine Tropfen entwickelt. Für die subtraktive Strukturierung werden an einem selbst entwickelten Versuchsaufbau die leistungs- und geschwindigkeitsabhängige Strukturbreite untersucht. Die Ergebnisse der beiden Technologieansätze werden verglichenWith help of thin layers of alkoxysilane molecules formed by self-assembly, the surface properties of solids can be controlled. Microstructured self-assembled monolayers (SAMs) are interesting for applications in components based on organic semiconductors. Two established technologies for the structuring of molecular monolayers are microcontact printing and photolithography, for which templates and masks need to be structured. In this way, setting times and costs are high if variable patterns have to be structured. In this work, the fabrication of laterally structured monolayers from octadecyltrichlorosilane (OTS) is demonstrated for two examples of alternative, both template-free and maskless technologies: (i) inkjet as a purely additive method, and (ii) photothermal laser desorption as a subtractive structuring of an OTS-SAM. For the inkjet technology, a method for the observation and analysis of the evaporation of a droplet is implemented at a goniometer and a mathematical model for small inkjet droplets is extrapolated, For the subtractive laser structuring, the achievable patterning resolution is investigated as a function of laser intensity and scanning speed. The results of both technological approaches are compared

Resumo: A incrustação durante a pasteurização de ovos ocorre principalmente devido à deposição de algumas proteínas que se coagulam quando aquecidas. O estudo de métodos que reduzam a formação de depósitos no pasteurizador é importante porque a incrustação representa um custo adicional para as indústrias. A incrustação causa uma diminuição da transferência de calor e a formação de sedimentos na embalagem ou no vaso de armazenamento. A incrustação traz como conseqüência a necessidade de um superdimensionamento dos pasteurizadores, desligamento periódico do pasteurizador para realização de limpeza, redução do tempo disponível para a produção, e o acúmulo de microrganismos que se protegem nas pequenas rugosidades do depósito comprometendo a qualidade microbiológica do produto final. O processo de incrustação foi estudado durante a pasteurização da clara de ovo, clara de ovo aditivada, ovo integral e ovo formulado. A incrustação foi influenciada pelos parâmetros de operação (tempo e temperatura de pasteurização) e pelas propriedades de cada produto (% de sólidos e pH) e foi avaliada através da variação de pressão do pasteurizador, do Coeficiente Global de transferência de Calor e da Resistência Térmica causada pela incrustação na seção de aquecimento. Durante as pasteurizações da clara de ovo aditivada e clara de ovo não ocorreram incrustações na seção de aquecimento. No entanto, ocorreram incrustações nas pasteurizações de ovo integral e ovo fonnulado, e foi possível a determinação de modelos lineares do Coeficiente Global de transferência de Calor e da Resistência Térmica causada pela incrustração, na seção de aquecimento, que predizem como o trocador de calor se comporta. A taxa de incrustação durante a pasteurização do ovo formulado foi maior que a do ovo integral, porque o ovo formulado contém maior teor de clara que o ovo integral. Estabeleceu-se o tempo máximo de operação do pasteurizador em 83 minutos para ovo integral, e 50 minutos para o ovo formulado a fim de obter uma redução de no máximo 30% do Coeficiente Global de Transferência de Calor. Durante a pasteurização de todos os produtos foi observado o aumento da pressão.
Abstract: Fouling during egg pasteurization occurs mainly due to the deposition of some proteins that coagulate when heated. The study of methods that reduce the formation of deposits in pasteurizer it' s important because fouling represents an additional cost to industries. Fouling causes a decrease ofheat transfer and formation of sediments at package or at storage tank. Fouling brings as a consequence the need of excess of surface area of pasteurizer, periodically switching ofI the pasteurizer to cleaning it, decrease of available time to production, and accmnulation of microorganisms that protect themselves in roughness of the deposit, committing microbiological quality of final product. Fouling process has been studied during pasteurizations of egg white, added egg white, and whole egg and formulated egg. Fouling was influenced by operation parameters (pasteurization time and temperature), and each product proprieties (solids % and pH), and it was evaluated through pasterurizer's pressure variance, through Heat Transfer Global Coefficient and Thermal Resistance caused by fouling at heating section. During added egg white and egg white's pasteurization, fouling didn't occur at heating sectÍon. However, in whole egg and formulated egg pasteurization occurred fouling, and it was possible to determinate linear models to Heat Transfer Global Coefficient and Thermal Resistance caused by fouling, in heating section, that predict how the heat exchange behaves. Fouling rate during formulated egg pasteurization was bigger than during whole egg, because formulated egg has got greater amount of white egg than the other. The maximmn time to operation of pasteurizer was established as 83 minutes to whole egg, and 50 minutes to formulated egg, so that it would be obtained a reduction of Heat Transfer Global Coefficient no bigger than 30%. During pasteurization of alI products it was observed pressure increase.
