Повний текст джерелаIn our study the texture of a set of model processed cheeses is characterized through both sensory and instrumental approaches. Three objectives guided our work. The first was using an individual approach that takes the diversity in terms of perception, manipulation and description into account for sensory characterization of products. Furthermore, to study the effect of prior expertise, two panels evaluated the products: consumer and expert panel. A combined approach with two different methodologies and verbalization (Free comment followed by Flash Profile) made it possible to identify specificities in the answer behavior between the two panels. Free comment showed the similarity and differences between the terminologies of two panels. It showed that experts generate more terms in average than consumers. However, some of their terms are specific and never was cited to consumers. Flash profile showed that there are some characteristics that become important once the assessors evaluate the products simultaneously. The result showed important differences between the resulted product maps from consumers and experts after free comment method. However, the resulted sensory maps after the Flash Profile were very similar for both panels and were close to the sensory map obtained for consumer panel after free comment. Some specific attributes were frequently cited for products evaluations in two applied methods, such as “Collant (Stickiness)”.The second objective was to establish the instrumental characterization on the basis of sensory results in order to better determine some efficient methodologies and conditions to characterize the identified perceptions. We thus used sensory descriptions and observations to choose appropriate instrumental methods. On this basis, classic rheological methods (measurement of the viscoelastic properties and penetrometry) and adapted tack method were used for product characterization. Furthermore, the products were characterized at two physical states (without or after a mechanical treatment). The adapted tack method and the rheology at small deformation with vane geometry permitted to characterize the products set with important texture diversity (solid, semi-solid, liquid). The results showed that the combination of two methods improves the product map and brings new axes of description. The instrumental characterization of mechanically treated products did not lead to a rather different products configuration.The third objective was to predict the sensory positioning of products (product map) as well as the specific multidimensional perception “Collant (Stickiness)”, by instrumental measurements. A rather satisfactory prediction of consumer perception of texture was obtained through viscoelastic measurements (storage module and yield stress) and parameters stemming from tack measurement (total energy and distance at maximum tensile force). Furthermore, the sensory perceptions relative to “Collant (Stickiness)” is well predicted by the instrumental parameter “yield stress” for the majority of the consumers who applied this term in their evaluations

Повний текст джерелаLao PDR is a landlocked country with low population density, which stands nowadays in a process of regional economic integration, after suffering wars related to decolonization and Cold War during several decades. A very fast economic growth, based on the development of infrastructures of transport and natural resource exploitation, has led to large differentiated impacts on populations and their resource based livelihoods. The concepts of resilience and vulnerability have been used in different disciplines to analyze and manage the dynamics of geographical areas and social groups facing rapid and uncertain changes. Both concepts are used within a variety of frameworks of analysis of society-environment relationships. While all reviewed frameworks take into account multiple scales of analysis in order to tackle the complexity of the studied phenomena, they do not, however, assess vulnerability and resilience at the same scales. In particular, some frameworks are actor-centered, while others are system-centered. The scale and limit of the socioecological system whose resilience or vulnerability is assessed depend on the issues that the authors want to tackle. Before such an assessment, it seems necessary to identify the issues of resilience and vulnerability that we want to address. This task should not be taken over by scientists alone, but by other stakeholders as well. The question is: how can we incorporate multiple viewpoints in the system design? For this, our framework considers a socioecological system both as a specific representation of the environment offered by a stakeholder, and as a set of elements contributing to one function. This system is organized in a hierarchy of levels of observation, in which each level corresponds to an intermediary function. We developed and tested a process to collect system representations of the environment from various stakeholders, that is to say, the way they structure a socioecological system that makes sense to them, according to the purposes that they assign to their environment. This approach has been tested in the catchment area of the Nam Lik river, Fuang district, Vientiane province, where the Nam Lik 1-2 hydropower dam was built in 2010. A series of workshops were held with residents of the study area, employees of local government and Lao National University teachers. At the earliest stage of a vulnerability or resilience assessment in the field study, this thesis proposes a reflection on the possible framings of these concepts, as well as methods to collect them from multiple stakeholders

Повний текст джерелаThe use of marketing research panels are a more and more frequently used source of information for studies within many different branches. The purpose of this report is to investigate the demographic composition of panels and compare it with the population of Sweden, a possible change in behaviour of respondents, and if the source of recruitment is the cause of possible differences in study results. The study was commissioned by Norstats Linkoping office. Sources for the data material include Norstat’s recruitment process and their two main panels with different recruitment sources. To enable a deeper investigation of behaviour we also constructed a survey that was sent to 2,714 members of Norstat’s internet panels.
The statistical analysis includes contingency table analysis, multiple logistic regression, and Poisson regression. The results show that the demographic composition does not fully cover all the aspects of the Swedish population and some groups are less represented than others. The behaviour tends to differ between panel members that have responded to three or less surveys compared to members that have responded to twenty or more surveys. Source of recruitment does not seem to affect the results of studies, but it has some effect on the demographic composition of marketing research panels.
Användandet av paneler som källa vid undersökningar har den senaste tiden blivit en allt vanligare företeelse. Denna rapport har för avsikt att undersöka panelers demografiska sammansättning och överensstämmande med Sveriges befolkning, eventuell ändring av svarsbeteende samt huruvida rekryteringskällan ger upphov till kvalitetsskillnader hos medlemmar i en panel. Företaget Norstat har med sitt kontor i Linköping figurerat som uppdragsgivare till arbetet. Datamaterialet till studien har uppkommit från Norstats rekryteringsprocess samt från företagets två huvudpaneler med olika rekryteringskällor. För att djupare undersöka svarsbeteende konstruerade vi även en enkätundersökning som skickades ut till 2 714 medlemmar i Norstats internetpaneler.
Den statiska analysen innefattar χ2-test, multipel logistisk regression samt Poissonregression. Resultaten påvisade att den demografiska sammansättningen i panelen inte fullt ut speglade Sveriges befolkning samt att vissa grupper undertäcks i högre utsträckning än andra. Svarsbeteendet hos medlemmar i paneler har en tendens att ändras från det att medlemmen har svarat på en till tre undersökningar, till det att den har svarat på tjugo undersökningar eller fler. Rekryteringskällan till en panel verkar inte ge upphov till några större skillnader i svarsresultat, men däremot finns vissa skillnader i demografisk sammansättning.

Повний текст джерелаCHARGE syndrome (CS) is a rare genetic disease characterized by numerous congenital abnormalities, mainly caused by de novo alterations of the CHD7 gene. It encodes a chromodomain protein, involved in the ATP-dependent remodeling of chromatin. The vast majority of CHD7 alterations consists in null alleles like deletions, non-sense substitutions or frameshift-causing variations. We report the first molecular diagnosis of an Indonesian CS patient by a targeted NGS (next-generation sequencing) gene panel (CHD7, EFTUD2, and HOXA1). We identified a novel heterozygous nonsense mutation in exon 34 of CHD7 (c.7234G>T or p.Glu2412Ter). Functional analyses to confirm the pathogenicity of CHD7 variants are lacking and urgently needed. Therefore, the aim of this study was to establish a functional test for wild-type (WT) or variants of CHD7 protein found in CS patients. Using an expression vector encoding CHD7, three variants harboring an amino acid substitution and one variant with a five-amino acid insertion were generated via site-directed mutagenesis. Then CHD7 proteins, either wild-type (WT) or variants, were overexpressed in HeLa cell line. Protein expression was highlighted by western blot and immunofluorescence. We then used real-time RT-PCR to study CHD7 functionality by evaluating the transcript amounts of five genes whose expression is regulated by CHD7 according to the literature. These reporter genes are 45S rDNA, SOX4, SOX10, ID2, and MYRF. We observed that, upon WT-CHD7 expression, the reporter gene transcriptions were downregulated, whereas the four variant alleles of CHD7 had no impact. This suggests that these alleles are not polymorphisms because the variant proteins appeared non-functional. Furthermore, we applied our biological assay in SH-SY5Y cell line in which endogenous CHD7 gene was mutated using the CRISPR/Cas9 technique. Then, we observed that when a CHD7 missense variant was expressed, the transcription levels of the five reporter genes were non-significantly different, compared with the cells in which both CHD7 alleles were knocked-out. Therefore, the studied variants can be considered as disease-causing of CS

Повний текст джерелаEsta dissertação visa estudar a performance corporativa dos clubes ingleses de futebol profissional, bem como os determinantes da performance dos clubes, com destaque para o efeito dos jogadores formados pelas Academias. O estudo evidencia existir uma associação positiva e significativa entre a performance financeira e desportiva dos clubes ingleses ao longo das épocas de 1993/94 a 2010/11. Os testes de cointegração indicam a existência uma relação estrutural de longo-prazo entre as variáveis desportivas e financeiras. Este estudo proporciona suporte à corrente da literatura que refere a maximização da performance desportiva sujeita a uma restrição de sustentabilidade financeira de longo prazo, como os principais objectivos dos clubes de futebol. Os testes de causalidade de Granger mostram que existe relações causais diferenciadas entre clubes. Os jogadores formados pelos próprios clubes tiveram um impacto negativo no desempenho desportivo e receitas, mas um efeito positivo na redução dos gastos salariais. A opção por jogadores formados por outros clubes ingleses teve uma influência negativa na performance desportiva, mas um efeito positivo na rendibilidade e despesas salariais dos clubes. Os resultados sugerem a necessidade de melhorar a produtividade do sistema de desenvolvimento de jovens jogadores em Inglaterra. Finalmente, observámos que os clubes ingleses são heterogéneos sinalizando a existência de peculiaridades em cada clube que são importantes para compreender o a performance alcançada e como desenvolvem as suas vantagens competitivas sustentáveis.
This dissertation examines the corporate performance of English professional football clubs and the determinants of clubs’ performance, with particular emphasis on homegrown locally-trained players. The study shows that there is a positive and significant association between the financial and sporting performance of English clubs over the 1993/94 to 2010/11 seasons. Cointegration tests show that sporting performance and financial variables are linked by a set of long-run structural relationship. Our study lends supports to the theoretical stream that argues that the maximisation of sporting goals, subject to constraint of long- term financial sustainability, are the two main objectives of football clubs. Granger causality tests show that there are different causal relationships between clubs. Homegrown club-trained players had a negative impact on the sporting performance and revenue functions, yet they had a positive effect on reducing salary expenditure. Association-trained players option had a negative influence on the sporting performance function, but a positive effect on profitability and wage expenses for English football clubs. The results suggest that there is a need to improve the productivity of the system for developing young players in England. Finally, we observed that English clubs are heterogeneous, which signals that idiosyncrasies exist in each club, which is important for understanding both performance and how to develop sustainable competitive advantages.

Повний текст джерелаThe study deals with the relationship between related party transactions (RPT\'s) and firm performance in the Brazilian \"Novo Mercado\", and its goal is to identify whether this relationship can be affected by mechanisms of corporate governance. Audit committee was used to measure corporate governance mechanisms. The two assumptions made by Gordon, Henry and Palia (2004), called \"conflicts of interest\" and \"efficient transactions\" were considered in this study. In an attempt to measure these relationships, it was adopted the model of panel data analysis to reduce the problem of omitted variable bias. The empirical results provide evidence that there is a relationship between related party transactions and firm performance. However, the results regarding the moderating effect of the mechanisms of supervision and use of such contracts have been inconclusive.

Повний текст джерелаIn classical finance theory investor sentiment is not considered an important factor in asset pricing. Although the existence of investor sentiment is not denied, theories assume that in competitive markets quasi-rational behavior is quickly offset by rational agents. The main goal of this thesis is to investigate the relationship between investor sentiment and future stock return rates. It is proposed a methodology to create a sentiment index specifically to the Brazilian market using principal components analysis. In order to analyze the relationship between this sentiment index and the future stock returns, it was estimated a pricing model including this variable for the period comprehending 1999 to 2008. Considering a negotiability restriction to assure representative and sufficient observations to validate a pricing model, the sample consisted of non-financial firms listed at BOVESPA. The pricing model was estimated by GMM considering the sentiment index, systematic risk (market beta) and factors as firm size, market-to-book ratio, leverage and return predictability measured by momentum or income growth. Different estimation procedures were applied to find empirical models coefficients which are less affected by spurious influence such as unobserved heterogeneity, outliers or possible regressors endogeneity. Results of the empirical study suggest that sentiment is a relevant factor in Brazilian asset pricing models. A negative and statistically significant relationship between the sentiment index and stock returns was consistently found in different models specifications. These findings suggest the existence of a reversion pattern in stock returns, meaning that after a positive sentiment period, the impact on subsequent stock returns is negative and vice-versa.

Повний текст джерелаUnderstanding the dynamics of persistence and evasion of export activity is essential for the design of export promotion for new exporters and international trade policies. Several results point to the importance of taking into account the specific sector of the industry in the implementation of public policies, which is supported by the new models of international trade theory. The purpose of this work is to investigate the determinants of the performance of Brazilian industrial new exporters, with particular attention to the impacts of Drawback, BNDES Exim and Proex. For this, we analyzed firms between the 1998 and 2003, constituting an unbalanced panel with 8500 firms. By panel data analysis and estimation of duration models, we found that the survival function and the growth of exports clearly differs among companies that use one of the programs and those that do not. One can also say that sunk costs are not negligible among the industrial firms analyzed, which indicates that public export promotion should focus on (i) reducing the dropout rate of new exporters and (ii) minimize the fixed sunk costs related with initial investments to begin the export activty.

Повний текст джерелаThe presentation describes how to analyze the impact of an idealized fragment into a stell protective panel with different dynamic analysis methods. Two different commercial Finite Element codes are used for this: a.) Creo Simulate: This code uses the method of modal superposition for analyzing the dynamic response of linear dynamic systems. Therefore, only modal damping and no contact can be used. The unknown force-vs.-time curve of the impact event cannot be computed, but must be assumed and applied as external force to the steel protective panel. As more dynamic the impact, as sooner the range of validity of the underlying linear model is left. b.) Abaqus/Explicit: This code uses a direct integration method for an incremental (step by step) solution of the underlying differential equation, which does not need a tangential stiffness matrix. In this way, matieral nonlinearities as well as contact can be obtained as one result of the FEM analysis. Even for extremely high-dynamic impacts, good results can be obtained. But, the nonlinear elasto-plastic material behavior with damage initiation and damage evolution must be characterized with a lot of effort. The principal difficulties of the material characterization are described

Повний текст джерелаThe Brazilian agriculture has grown in recent decades and productivity gains have been important in this good performance of the sector. This work had two main objectives. The first one was measure the growth of this total factor productivity in agriculture by the Brazilian\'s states, decomposing TFP growth by technological progress, technical efficiency and economies of scale. The second objective was to analyze the effect of TFP growth of Brazilian agriculture on agricultural prices. The growth in productivity was measured from the inputs like labor, gross and capital in the translog production function, from the Stochastic Frontier Analysis and of the outputoriented Malmquist productivity index. To analyze the effect of TFP growth on agricultural prices was constructed an index of agricultural prices through the Laspeyres price index to estimate the vector autoregressive panel (panel-VAR) and establish the relationships between TFP, rural wages, agricultural finance and income per capita household. The Granger causality test and the impulse response function were used to the data panel. The database used obtained from the Agricultural Census, at the state level for the years 1970, 1975, 1980, 1985, 1995 and 2006. The results showed that the growth rate of TFP has been growing in Brazil and in the states, and technological progress explained most of the growth being positive and growing for all states. Technical efficiency varied over the years, presented positive average growth rates for most states. The states were located below the production frontier of Brazilian agriculture and São Paulo was the state with the highest level of technical efficiency. Although the average annual growth rate has been increasing over the period analyzed, the efficiency decreased to all state analyzed in 2006. The results also showed that TFP growth has causality in the sense of Granger, on agricultural prices. In the impulse response function, the initial shock in TFP decreased prices in the early years. Thus, TFP growth of the agricultural sector contributed to the increased supply of agricultural products, reducing agricultural prices. The greater availability of food and with reducing food prices, consumers, especially those from lower income might had greater access to food.

Повний текст джерелаThe seismic vulnerabilty is an important issue in the design of a building. The seismicresistant behavior of timber-framed structures is particularly relevant. Two types of timberframedstructures can be distinguished : the timber-framed structures using industrial products,such as wood-products panels used to brace the structure or metal fasteners, and traditionaltimber-framed structures included infill made of natuarl materials (earth or stones masonry).The seismic resistant behavior efficiency of traditional structures remains poorly recognizedbecause of the lack of research results on this kind of construction.Therefore, the thesis aims at improving the seismic behavior knowledge of timber-framedmasonry. Based on the assumption that their behavior is driven by the response of the metalfasteners connections, a multi-scale approach is proposed. It couples experimental and numericalstudies. At the scale 1 of the connection, at the scale 2 of the elementary constitutive cell ofwalls, at the scale 3 of structural elements such as shear walls and finally at the scale 4 of theentire building.In regards to the experimental work, this method allows, on the one hand, to perform parametricstudies and to analyze the influence of each element (wood member, nails, steel strip,infill, bracing, openings) on the local behavior (scales 1 and 2) and on the global behavior(scales 3 and 4) of the structure. On the other hand, it allows to provide a database to validatethe numerical modeling at each scale.In regards to the numerical work, this multi-scale approach allows to take into account thehysteretic behavior of joints in the development of a macro-element at the scale 2. Thus, thanksto a simplified finite element modeling (macro-element assembly), the computational cost islimited and it allows to take into account the local phenomena. The model is able to predictrelatively accurately the dynamic behavior at the scale 4 of the building, tested on a shakingtable.The study, presented herein, is one of the pioneer work that deals with the analysis of theseismic vulnerability of timber-framed structures with infill panels. This study provides outlookfor the analysis of this type of buildings. It confirms that the timbered masonry structures havea relevant seismic resistant behavior

Повний текст джерелаSensory analysis is a scientific method used to measure, analyze and interpret reactions related to product characteristics such as perceived through the senses, responding to much more than simply preference for one product over another. Specific scientific methods have been developed to measure or estimate objectively, accurately and reproducibility human responses to stimuli that they are submitted. Descriptive tests, which are part of sensory analysis, require careful control of possible variables that can affect the results, such as test environment, sample storage, skin conditions of the panelists, product attributes selection and training. The training philosophy is to provide the same sensory experience to panelists through the use of a wide variety of references samples, concepts, terminology, protocols, and scales, which is essential to establish a common frame of reference, whose purpose is to remove the\"subjective\" connotation from this sensory methodology. By using this methodology, we achieved consistente, similar and with small standard deviations answers, after three months of training with the panel, which was able to distinguish seven moisturizers commercial products into the studied attributes

Повний текст джерелаThe second chapter proposes LM type panel unit root test procedures with structural changes based on the group mean and combination test approaches. The proposed test procedures allow for breaks under both the null and alternative, and capture heterogeneity due to individual specific characteristics. The same set of distributions of the underlying individual LM statistics can be utilized to compute the panel statistics for the cases with no breaks and with intercept breaks as a result of the invariance property. Simulation results demonstrate that the inverse normal test exhibits the best overall finite-sample properties measured in terms of size and power. When break dates are unknown, the minimum sum of squared residuals break selection method is preferred. The bootstrap approach is suggested to account for cross-sectional dependence.
The third chapter studies panel cointegration tests dealing with two manifestations of structural changes, viz. breaks in the cointegrating relationship and breaks in the trend functions of time series. The importance of accounting for these breaks is highlighted using a simulation study. Finite-sample properties of the Gregory-Hansen (GH) type and LM type tests incorporating breaks in the cointegrating relationship are assessed. Two variants of the LM type tests are further examined in the presence of cross-sectional dependence taking on a factor structure. In the course of test comparison, some modifications are also suggested. A novel test procedure, based on the LM approach, is devised when trend functions of time series are subjected to breaks. Unlike existing tests, this procedure permits unknown breaks under both the null and alternative that can differ in locations among the variables under study.
This thesis investigates panel unit root and cointegration tests with structural changes that are generalizations of their univariate counterparts. Small-sample properties of two well-established univariate test procedures are first assessed using the bootstrap approach. Extensions of these procedures in the panel framework are then examined.

Повний текст джерелаA madeira lamelada-cruzada (cross-laminated timber, CLT), tendência moderna em termos de construção em madeira, demonstra elevado potencial para sistemas maciços de construção de madeira. O conceito dos painéis CLT (camadas ortogonais) reduz significativamente a anisotropia dos painéis, garante maior estabilidade física e permite ligações mais fáceis e eficientes entre os elementos e destes com outros componentes da construção, tornando esses painéis uma solução versátil para suportar cargas fora/ e no plano dos mesmos. Este sistema possui vantagens significativas em relação à construção das tradicionais estruturas leves de madeira, abrindo um campo completamente novo para o uso da madeira na construção. Por outro lado, como se trata de um sistema maciço de madeira, é necessário um volume significativo de matéria-prima para produzir os painéis, aspeto que é apontado como uma das principais barreiras para a implementação do CLT de uma forma mais abrangente, porventura devido aos custos associados. Neste contexto, o objetivo da presente tese consistiu no desenvolvimento de uma solução de painel alternativa, ou pelo menos complementar, baseada em CLT, mas utilizando menos quantidade de madeira, combinando desempenho mecânico com melhor isolamento térmico e peso reduzido. A solução desenvolvida, denominada madeira isolada cruzada (cross-insulated timber, CIT), consiste em substituir a camada interna de um painel CLT de cinco camadas por uma à base de material de isolamento (espuma rígida de poliuretano), tendo, por isso, algumas semelhanças com o conceito de painel de madeira estrutural isolado (SIP). Os principais aspetos focados nesta tese, tendo em vista o desenvolvimento do painel incluem: (i) a definição da estrutura do painel e dos possíveis materiais para a sua constituição; (ii) a caracterização dos materiais selecionados para o desenvolvimento do painel, incluindo as camadas adesivas; (iii) a caracterização mecânica dos painéis; (iv) a otimização funcional e económica dos painéis; (v) a avaliação do impacte ambiental dos painéis; (vi) a caracterização acústica dos painéis; e (vii) o desenvolvimento de sistemas de conexão para os painéis. No primeiro aspeto, foi definida uma estrutura composta por um núcleo em espuma rígida de poliuretano entre dois pares de camadas cruzadas em madeira de Pinho bravo. Em alternativa, para as faces exteriores dos painéis, foi também considerada a Acácia Austrália. No segundo aspeto, os resultados de caracterização dos materiais permitiram verificar o comportamento complexo da espuma de poliuretano, tendo-se observado um comportamento não-linear e rotura dúctil em compressão e um comportamento linear e rotura frágil em tração. Da adesão entre materiais, concluiu-se que as adoção de pressões de aperto mais elevadas conduzem a uma melhor adesão dos mesmos e, dos ensaios de envelhecimento, concluiu-se que ao invés de uma redução da resistência, particularmente no poliuretano, houve um aumento da mesma devido à pós-reticulação do material. No terceiro aspeto, foi possível verificar que o modo de rotura dominante nos ensaios de flexão foi o corte do núcleo. Os modelos analíticos identificados na revisão do estado-da-arte descreveram bem o comportamento inicial observado (linear) e, para descrever a fase não-linear observada, os modelos numéricos desenvolvidos demonstraram um bom nível de precisão. No quarto aspeto, concluiu-se que a exigência de um desempenho térmico mínimo (envolvente exterior do edifício) torna a solução de painel desenvolvido na tese mais competitiva face aos painéis CLT. No quinto aspeto, através de uma análise de ciclo-de-vida, concluiu-se que a produção de poliuretano e a assemblagem do painel constituem os processos de produção com maior impacte ambiental; dos cenários de fim-de-vida considerados, a opção de incineração com recuperação de energia revelou ser a que implica menores impactes. Da comparação com sistemas de CLT, concluiu-se que o painel desenvolvido implica, de uma forma geral, maiores impactes. No sexto aspeto, verificou-se, o menor isolamento dos painéis de CIT face aos de CLT de igual espessura, devido à menor massa. Os modelos analíticos identificados no estado-da-arte para painéis sanduiche não se revelaram adequados para avaliação do isolamento a sons aéreos dos painéis, pelo que o modelo de Sharp para elementos isotrópicos e homogéneos com uma adaptação revelou uma melhor descrição dos mesmos; para descrição do isolamento a sons de percussão, a lei do invariante revelou-se eficaz. No sétimo aspeto foram desenvolvidas várias ligações, sendo que uma delas foi testada experimentalmente, e cuja resistência se enquadrou dentro do previsto pelos modelos analíticos identificados no estado-da-arte. Globalmente, o estudo realizado nesta tese mostrou que os painéis desenvolvidos têm potencial para complementar os atuais sistemas em CLT, nomeadamente no que diz respeito ao aos elementos da envolvente exterior.
Cross-Laminated Timber (CLT), a modern trend in timber construction, shows high potential for massive timber construction systems. Compared to traditional systems, the CLT panels’ layout (crosswise layers) significantly reduces the anisotropy of the panels, guarantees higher physical stability and allows for easier and more efficient connections between elements and other building components, making these panels a versatile solution to bear both out-of-plane and in-plane loads. This system has also significant advantages with respect to traditional wood light-frame construction, opening a completely new field for the use of timber in construction. On the other hand, as this is a massive wood system, a significant volume of wood raw material is required to produce the panels and this is pointed out as one of the main barriers for CLT implementation, perhaps due to the associated costs. In this context, the objective of the present thesis consisted of the development of an alternative, or at least complementary, CLT based panel solution but using less amount of wood, combining mechanical performance with improved thermal insulation and reduced weight. Such solution, named cross insulated timber (CIT), consists of replacing the inner layer of a five-layer CLT panel by an alternative one made of insulation material (polyurethane rigid foam), and thus having some similarities with the structural insulated timber panel (SIP) concept. The main aspects that are focused on this thesis for the panel development, include: (i) the definition of the panel layout and potential materials for its constitution; (ii) the characterization of the selected materials for the panel development, including the adhesive layers; (iii) the mechanical characterization of the panels; (iv) the functional and economic optimization of the panels; (v) the evaluation of the environmental impact of the panels; (vi) the acoustic characterization of the panels; (vii) the development of connection systems for the panels. In the first aspect, a structure consisting of a polyurethane core between two pairs of Maritime pine crossed layers was defined. As an alternative to this, for the exterior faces of the panels, Acacia Australia was considered. In the second aspect, the results of material characterization tests allowed to verify the complex behaviour of the polyurethane foam, which presents non-linear behaviour and ductile failure in compression, and linear behaviour and brittle failure in tension. From the adhesion between materials, it was concluded that the adoption of higher bonding pressures leads to better adhesion of the same ones and, from the ageing tests, it was concluded that instead of a reduction in strength, particularly in polyurethane, there was a strength increase due to additional cross-linking due to post-curing. In the third aspect, it was possible to verify that the dominant failure mode in the bending tests was core shearing. The analytical models identified in the state-of-the-art review described well the observed initial behaviour (linear) and, to describe the observed nonlinear phase, the numerical models developed demonstrated a good level of precision. In the fourth aspect, it was concluded that the requirement of a minimum thermal performance (in the case of the exterior envelope of the building) makes the panel solution more competitive against CLT panels. In the fifth aspect, through a life-cycle analysis, it was concluded that the production of polyurethane and the assembly of the panel constitute the production processes with the greatest environmental impact; among the considered end-of-life scenarios, the option of incineration with energy recovery proved to be the one with the least impacts. From the comparison with CLT systems, it was concluded that the developed panel presented, in general, greater impacts. In the sixth aspect, less insulation of the CIT panels compared to the CLT panels of equal thickness was registered, due to the lower mass. The analytical models identified in the state-of-the-art for sandwich panels did not prove to be suitable for assessing the airborne sound insulation of the panels, so the Sharp model for isotropic and homogeneous elements with an adaptation provided more accurate predictions; for describing the insulation to impact sounds, the invariant law proved to be effective. In the seventh aspect, several connections were developed, one of which was experimentally tested, and whose resistance fit within the predictions provided by the analytical models identified in the state-of-the-art. Overall, the study conducted in this thesis showed that the developed panels have the potential to complement the current CLT systems, namely concerning the elements of the external envelope.

Повний текст джерелаBread is one of the most consumed products in the world, and therefore essential for a healthy, complete and balanced diet. In Portugal, despite being an integral part of population’s eating habits, its intake has declined in recent years due to changes in consumption patterns. In a time when consumers are increasingly demanding, looking for convenient, fresh and quality products, bread has been forced to evolve. Presenting a variety of shapes and formats in a way that captivates these consumers, however, bread evolution is strongly influenced by parameters such as freshness, color and texture, being freshness a complex and very difficult parameter to describe and evaluate having into account the variety of breads that exist. Concluding, the main objective of this project was to develop a trained panel as a tool to evaluate the characteristics of bread considered traditional by the company and, in this way, finding points that can be improved by improving the quality of the bread in question. Thus, combining the growing emphasis that sensorial analysis has received in recent years, to the optimization of a traditional product. In this work the different phases for the constitution of a panel of trained tasters are described, as well as their selection and training according to the standards of the sensorial analysis.
