In industry, the fillet production cost is high because of the low fish utilization, which in turn, it generates residues that can potentially be transformed into commercially viable by-products, such as mechanically separated meat (MSM). In this sense, this work aims to improve the nutritional quality of Nile tilapia MSM (Oreochromis niloticus) through the pressing process for the elaboration of new products with added value. The present study was divided in two stages: 1st stage - Study the effect of pressing process on the nutritional quality of the Nile tilapia MSM and the effect of the addition fish-based condiment on development of the MSM patties (article 1). The results showed that the pressing process improves the nutritional quality of the tilapia MSM and the addition fish-based condiment in the patties provides a better sensorial acceptance of the product. In the 2nd stage - Evaluates the effects of the addition of pregelatinized starch and dextrin in the preparation of MSM patties obtained from fillet waste from Nile tilapia (Article 2). The results demonstrated that the addition of pregelatinized starch and dextrin improves the texture of tilapia MSM patties, as well as their sensorial characteristics. Based on the data obtained, it can be concluded that the residues (carcass) generated in the process of fillet processing can be a viable alternative as raw material for the elaboration of new structured products, adding value and enabling the fish processing industry to increase profits. / A preferência do consumo da carne de tilápia pelos brasileiros é representada pelo filé, sendo este o principal produto comercializado pelas indústrias que beneficiam a espécie. O custo de produção de filé é elevado, em virtude do baixo aproveitamento do pescado, em contrapartida, gera resíduos que potencialmente podem ser transformados em subprodutos com aproveitamento mercadológico, como é o caso da carne mecanicamente separada (CMS). Nesse sentido, este trabalho teve por objetivo melhorar a qualidade nutricional da CMS de tilápia do Nilo (Oreochromis niloticus) através do processo de prensagem para a elaboração de novos produtos com valor agregado. O presente estudo foi dividido em duas etapas: 1º etapa - Estuda a influência do efeito da prensagem sobre a qualidade nutricional da CMS de tilápia do Nilo e o efeito da adição de condimentos a base de peixe no desenvolvimento de empanados com CMS (artigo 1). Os resultados demostraram que o processo de prensagem melhora a qualidade nutricional da CMS de tilápia e a adição de condimentos a base de peixe nos empanados proporciona uma melhor aceitação sensorial do produto. Na 2º etapa – Avaliou-se o efeito da adição de amido pré-gelatinizado e dextrina na preparação de empanados de CMS da carcaça de tilápia do Nilo (artigo 2). Os resultados demostraram que a adição de amido pré-gelatinizado e dextrina melhora a textura dos empanados de CMS de tilápia, assim como suas características sensoriais. Baseados nos dados obtidos pode-se concluir que o subproduto da filetagem de tilápia do Nilo (carcaça) gerados no processo de beneficiamento do filé são uma alternativa viável como matéria prima para a elaboração de novos produtos restruturados, agregando valor, e possibilitando a indústria de beneficiamento de pescado um incremento nos lucros.

<p>The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model. First measurements were conducted with the system, including measurements with phantom media (Intralipid-ink solutions) and with cartilage samples taken from the human knee joint. This work also includes an investigation about the preparation of tissue samples for optical measurements.</p>

Logistics plays a crucial role in companies’ ability to sustain competitive on the market. Time is regarded as one of the important metric in terms of logistics, since time influences the lead time of the products, which results in the vital advantage of speed. The recent business environment forces Kinnarps Production AB, a manufacturer of furniture, to optimize their inventory material flow in a way of increasing their capability and capacity to load more distribution containers with goods daily. The present circumstances of the material flow are associated with number of negative factors. An automated guided vehicle (AGV) system is operating and handling the distribution of goods. Wrong sequence of activities, long transportations, high transportation delays, waiting time, varying numbers of AGVs, wastes, bottlenecks are among the important issues to be considered. The purpose of this thesis is to analyze the material flow in Kinnarps Production AB’s inventory seven and to improve the AGV system activities within. Concepts associated with identifying waste were used by separating value-adding activities from the non-value added ones. The usage of ideal reference systems techniques were the base for identifying problems. Concrete literature regarding AGV’s design system was applied in establishing different statements about the material flow and identification of problems. Different methods and techniques were used in approaching the research, but most above others is the case study approach. Numerous amounts of secondary data have been employed in verifying the collection of other data carried out by primary data collection as well as verifying the qualitative and quantitative analysis. A mapping of the current system was established with respect to orders, times and distances. Numbers of congestion points were identified, non-value adding activities were eliminated or decreased, rearrangement of sequencing of different activities was considered and different pallets arrangement system was established. A stochastic model was used in identifying the AGV’s time variables in the system and estimating appropriate amount of AGVs within the inventory. All the findings from different calculations and estimations were associated with Kinnarps Production’s future increased demand. Different issues and considerations were analyzed and appropriate suggestions were given for elimination of the negative factors in the inventory or their decrease. Among the most influencing results was the proper amount of AGVs in the inventory area, pallets rearrangement, different stocking policy, rearrangement in the sequence of activities, increase of the buffer for pallets used for loading containers, new conveyor system for the incoming goods in the inventory, transportation layout changes resulting in blocking free routines, separate control system, decrease of the effect of stoppages. All these findings are considered to optimize the material flow and increase the system capacity contributing to an increase of the daily containers outgoing from Kinnarps Production AB.

There has been an increase of the consumption rate and consumers are buying garments that they dispose in too early of a stage of the product lifecycle. This has caused an increase regarding landfill of waste. The aspect of implementing environmental oriented material science and garment technology has not been taken into consideration in the design process, something that quickly became an issue when the consumption rate increased. Therefore it is essential to rethink and restructure the business models applied today. The implementation of a circular economy, which focuses on giving textiles and garments a second life and basing production on used fibres whilst not harming the natural resources in the process, is a good start of the long journey to recovery which lies ahead. Both fast fashion companies and premium lifestyle brands are nowadays applying and integrating new business models into their daily operations, Tommy Hilfiger is an example of such a company. Purpose: The purpose of this thesis is to explore the relationship between material science, garment technology and the concept of circular economies from a premium lifestyle brand perspective The researcher will explore how material science and garment technology can prevent faulty items and short product lifecycles. Furthermore, the researcher will investigate how a company develops underwear collections with regards to material science, garment technology, and the concept of circular economies. The company Tommy Hilfiger will be implemented as an exponent throughout this report. Research questions: • What is the relationship between material science, garment technology, and the concept of circular economies? • What does a premium lifestyle brand take into consideration regarding the concept of circular economies when developing a collection of underwear? Methodology: This thesis was conducted by applying a qualitative method and by implementing a deductive approach. The gathering of secondary data was done through assembling suitable concepts and theories. The researcher collected the primary data through a participating observation and four qualitative interviews. The participating observation corresponded of an internship at the European headquarters of Tommy Hilfiger in Amsterdam, Netherlands. The researcher executed the interviews via email with key people within the departments of Design, Production, Central Sourcing and Production, and Corporate Responsibility. Conclusion: Material science and garment technology are correlated given that the choice of material and manufacturing technique utilized in production determines the durability and sustainability level of the fabric output. Therefore the two concepts are further correlated to the product aspect, which can enable a closed textile value chain loop, of a circular economy based business model. A premium lifestyle brand takes the aspects of design out waste, build resilience through diversity, work towards using energy from renewable sources, and think in consecutive processes into consideration regarding the concept of circular economies when developing a collection of underwear.

An accurate and generalized global retrieval algorithm from satellite observations is a prerequisite to understand the radiative effect of atmospheric aerosols on the climate system. Current operational aerosol retrieval algorithms are limited by the inversion schemes and suffering from the non-uniqueness problem. In order to solve these issues, a new algorithm is developed for the retrieval of non-spherical dust aerosol over land using multi-angular radiance and polarized measurements of the POLDER (POLarization and Directionality of the Earth’s Reflectances) and wide spectral high-resolution measurements of the MODIS (MODerate resolution Imaging Spectro-radiometer). As the first step to account for the non-sphericity of irregularly shaped dust aerosols in the light scattering problem, the spheroidal model is introduced. To solve the basic electromagnetic wave scattering problem by a single spheroid, we developed an algorithm, by transforming the transcendental infinite-continued-fraction-formeigen equation into a symmetric tri-diagonal linear system, for the calculation of the spheroidal angle function, radial functions of the first and second kind, as well as the corresponding first order derivatives. A database is developed subsequently to calculate the bulk scattering properties of dust aerosols for each channel of the satellite instruments. For the purpose of simulation of satellite observations, a code is developed to solve the VRTE (Vector Radiative Transfer Equation) for the coupled atmosphere-surface system using the adding-doubling technique. An alternative fast algorithm, where all the solid angle integrals are converted to summations on an icosahedral grid, is also proposed to speed-up the code. To make the model applicable to various land and ocean surfaces, a surface BRDF (Bidirectional Reflectance Distribution Function) library is embedded into the code. Considering the complimentary features of the MODIS and the POLDER, the collocated measurements of these two satellites are used in the retrieval process. To reduce the time spent on the simulation of dust aerosol scattering properties, a single-scattering property database of tri-axial ellipsoid is incorporated. In addition, atmospheric molecule correction is considered using the LBLRTM (Line-By-Line Ra- diative Transfer Model). The Levenberg-Marquardt method was employed to retrieve all the interested dust aerosol parameters and surface parameters simultaneously. As an example, dust aerosol properties retrieved over the Sahara Desert are presented.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlegårdarna, renovates and improves the energy efficiency at some of it’s apartment buildings in the district Sätra, Gävle. One problem is how to make the basic design of the slab on ground more energy efficiency and moisture proof. The study covers four representative flooring types in the Gavlegårdarnas million program area in Sätra. This study aims to investigate and evaluate proven methods for adding insulation in the four floor types. Also to look for solutions by designing additional insulation to treat damp problems and improve energy efficiency in an economical way. Existing flooring types are to be examined to check for new solutions as well. The aim is to produce a number of measures to provide property owners with different energy efficiency solutions. Results of calculations show that the perimeter area of the slab is exposed to moisture problems, while the centre of it does not have any notable problems. According to calculations, improved floor types have U-values reduced by 31% – 40% depending on the insulation thickness and design. However, investments have a long payback period and this is sometimes not economically viable. When a redevelopment project is performed, it is beneficial to simultaneously add insulation. If investors promote sustainable development, reduced energy consumption by the proposed measures is viable, as advocated by the environmental goals set by Sweden and the EU. / Sveriges riksdag beslutade att det skulle byggas en miljon bostäder, så kallade miljonprogramshus, mellan åren 1965 och 1974. Miljonprogramshusen uppfördes med nya och obeprövade konstruktionslösningar, på kort tid och till låga kostnader. Idag är bostadshusen från den tiden i stort behov av renovering. Det kommunalägda bostadsbolaget Gavlegårdarna håller på att renovera och energieffektivisera några av sina flerbostadshus i stadsdelen Sätra, Gävle. Ett problem är hur grundkonstruktionen, platta på mark i flerbostadshusen ska energieffektiviseras och fuktsäkras. Denna undersökning behandlar fyra representativa golvkonstruktioner som förekommer i Gavlegårdarnas miljonprogramsområde i Sätra. Syftet med undersökningen är att studera och utvärdera beprövade metoder för tilläggsisolering på de fyra utvalda golvtyperna. Lösningsförslagen på tilläggsisoleringsåtgärderna ska behandla fuktproblem, ekonomi och energieffektivisering. Resultaten från undersökningen visar att markplattans kantbalk är utsatt för fuktproblem medan plattans mitt inte har några anmärkningsvärda problem. Enligt U- värdesberäkningarna förbättras golvtypernas U-värde med 31 % - 40 % beroende på isoleringstjocklek och utförande, dock har investeringarna långa återbetalningstider. Utförs ett renoveringsarbete är det fördelaktigt att samtidigt tilläggsisolera. Satsar investerarna på en hållbar utveckling med minskad energianvändning rekommenderas förslagna åtgärderna, vilket förespråkas i miljömål uppsatta av Sverige och EU.

The aim of this work was to study the agricultural enterprises management which are directed to guava production destined to processing in the biggest producing region of São Paulo state, comparing, through the indicators, the verified results in the agricultural enterprises in which the production verticalization was used, to the obtained ones by the producers who produce the raw material and deliver it to the processing. The study method of multiple cases was chosen for the accomplishment of the work empirical part. It was observed that characteristics such as scholarship low level and the familiar labor participation are common to almost all studied producers, being or not own raw material processors. It was also observed that, only the agricultural producers, who process their productions and are considered great, control the guava production costs. It is verified that the value aggregation to the raw material before trading really contributes for the reach of an agricultural business better performance in the economic, social and environmental dimensions. The main advantage for the producers who verticalized their productions is the best remuneration gotten for the raw material, contributing for the permanence in the sector and reducing the dependence of the raw material sales business for the region processors. The local development as a result of the value aggregation is also verified, through more work ranks generation, income distribution and life quality improvement of the involved ones. Amongst the restrictions of the production verticalization the management tools use absence is emphasized, information register and analysis methods, entry difficulty in the markets for the products trading, specially the international ones, and the price competition of the small clandestine processor products. The majority of the producers did not professionalize the management of their businesses mainly for cultural questions which bring from the land succession process, no matter adding or not value to the production. This study shows the necessity of changing the agricultural producer profile and evidences of adding value to his production is a suitable way to reach the sustainability and the sector permanence. / A utilização da integração vertical na produção de goiaba no estado de São Paulo apresenta-se como uma estratégia que auxilia os produtores rurais no alcance gradativo da sustentabilidade do negócio nas dimensões econômica, social e ambiental. Este trabalho teve como objetivo estudar a gestão de empreendimentos rurais que se dedicam à produção de goiaba destinada ao processamento na maior região produtora do estado de São Paulo, comparando, através de indicadores, os resultados verificados nos empreendimentos rurais que optaram pela verticalização da produção com os obtidos pelos produtores que produzem a matéria-prima e a entregam para o processamento. O método de estudo de casos múltiplos foi escolhido para a realização da parte empírica do trabalho. Observou-se que características como baixo nível de escolaridade e participação da mão-de-obra familiar são comuns a quase todos os produtores estudados, sejam processadores ou não da matériaprima própria. Observa-se também que, somente os produtores rurais que processam suas produções e que são considerados grandes, controlam os custos de produção da goiaba. Verifica-se que, realmente, a agregação de valor à matéria-prima antes da comercialização contribui para o alcance de uma melhor performance do negócio rural nas dimensões econômicas, social e ambiental. A principal vantagem para os produtores que verticalizam suas produções é a melhor remuneração obtida pela matéria-prima, contribuindo para a permanência no setor e reduzindo a dependência das transações de venda da matéria-prima para as processadoras da região. Também verifica-se o desenvolvimento local proporcionado pela agregação de valor, através geração de mais postos de trabalho, distribuição de renda e melhoria na qualidade de vida dos envolvidos. Dentre as restrições da verticalização da produção destacam-se a ausência da utilização ferramentas de gestão, métodos de registro e análise de informações, dificuldade de penetração nos mercados para a comercialização dos produtos, sobretudo internacionais, e a concorrência dos preços dos produtos de pequenas processadoras clandestinas. A maioria dos produtores não profissionalizou a gestão de seus negócios principalmente por questões culturais que trazem do processo de sucessão da terra, independentemente de agregarem ou não valor à produção. Este estudo mostra a necessidade da mudança do perfil do produtor rural e evidencia que agregar valor à sua produção é uma forma adequada para atingir a sustentabilidade e a permanência no setor.
