Différenciation de filets de poisson frais de filets congelés/décongelés sur le modèle du bar (Dicentrarchus labrax) / Differentiation of fresh fish fillets and frozen/thawed fillets using European sea bass (Dicentrarchus labrax) as a model

Marlard, Sylvain 20 December 2013 (has links)
En alimentation humaine, le poisson représente non seulement une source importante de protéines mais il apporte aussi des acides gras essentiels et des minéraux. Actuellement, en France, il est majoritairement consommé sous forme fraîche et préparé en filets sans peau. Cependant, face à la diminution des captures, à l'augmentation de la demande et à l'évolution des modes de consommation, l'importation de produits de la mer est de plus en plus importante dans notre pays. Or, depuis quelques années, les importateurs suspectent des fraudes consistant à vendre des filets de poisson décongelés sous la dénomination "frais". Ces produits entrent ainsi en concurrence directe avec les produits de la pêche française. L'objectif de la thèse consiste à mettre au point et à optimiser des méthodes de différenciation des filets de poisson frais de filets décongelés. La technique de l'électrophorèse bidimensionnelle comparative couplée à la spectrométrie de masse nous a permis d'identifier la parvalbumine comme marqueur de différenciation frais/décongelé à partir des exsudats de filets de bar (Dicentrarchus labrax). Nous avons utilisé la composition des exsudats comme source potentielle d'autres indicateurs pour différencier les filets frais des filets décongelés. Nous nous sommes ainsi intéressés à différents paramètres tels que l'activité de l'α-glucosidase lysosomique (marqueur historique), le dosage du calcium libre et le dosage des nucléotides et de leurs dérivés, des protéines et des parvalbumines. Nous avons procédé à une analyse statistique par Classification Hiérarchique Ascendante (CHA) et nous avons ainsi mis en évidence trois groupes dissimilaires : les indicateurs de lyse cellulaire, les indicateurs d'altération des nucléotides et les indicateurs d'altération des protéines. Nous disposons ainsi d'outils de différenciation frais/décongelé complémentaires, rapides et peu onéreux susceptibles de répondre aux attentes des industriels de la filière. / Inhuman diet, seafood is an important source of proteins, essential fatty acids and minerals. Nowadays, in France, fresh fish is mainly consumed as skinless fillets. Due to the decrease of the fishing and the increase and evolution of fish consumption, the importation of fish becomes more significant in our country. Since several years, the importers suspect fraudulent pratices consisting in selling thawed fish fillets labeled as fresh ones. These products are directly in competition with the national fish market. The main aim of this thesis consisted in developing and improving methods to differentiate fresh versus frozen/thawed fish fillets. A comparative two-dimensional electrophoresis and tandem mass spectrometry proteins identification strategy, performed on fish fillet exudates of European sea bass (Dicentrarchus labrax) allowed us to identify parvalbumin as a protein marker for differentiation. Further analysis of exudates composition could be a good way to find other indicators. The lysosomal alpha-glucosodase activity is already used to differentiate fresh versus frozen/thawed fillets. Two new indicators were studied : concentration of the nucleotides and their derivatives and free calcium concentration. The total protein and the parvalbumin concentrations were also measured. An Ascendant Hierarchical Clustering (AHC) was done to aggregate the variables into three dissimular clusters : the cellular lysis indicators, the proteins damages indicators and the nucleotides alteration.

Automação do processo de corte e dobra de armaduras para estruturas de concreto integrada ao processo BIM. / Automation of the cutting and bending process of reinforcing bars for concrete structures integrated to the BIM process.

Maciel, Alex Roda 29 May 2018 (has links)
A consolidação do processo de Modelagem da Informação da Construção (BIM) tende a contribuir para o aumento da eficiência da indústria da construção civil, fomentando novos fluxos de trabalho e permitindo o reuso de informações ao longo do ciclo de vida dos empreendimentos. Apesar do potencial de integração e automação associados ao processo BIM, o uso das informações digitais contidas no modelo para facilitar a pré-fabricação de produtos para a construção mostra-se incipiente. Nota-se que emprego da fabricação digital encontra obstáculos sobretudo em setores que atuam de modo segregado, e que por isto mesmo demandam sinergia, bem como o uso de normas e padrões que possibilitem a interoperabilidade e reuso das informações geradas nas fases anteriores a fabricação. Neste contexto, foi feita uma análise do uso da fabricação digital aplicada ao processamento industrial de aço para estruturas de concreto armado (corte e dobra). Embora os fabricantes que atuam neste setor possuam suporte a interface digital com os demais agentes, a configuração de sua cadeia de produtiva, bem como os processos tradicionalmente adotados, promovem a ocorrência de ilhas de automação ligadas por transferência manual e reentrada de dados. Como forma de reduzir a intervenção manual para a transcrição dos dados, propõe-se o uso do esquema de dados Industry Foundation Classes (IFC) na fabricação digital de componentes de armadura. Este trabalho tem por objetivo apresentar uma solução técnica, baseada no esquema IFC, aos requisitos de troca de informação necessários no fluxo de trabalho proposto. Com base nos requisitos de troca identificados por meio do método Information Delivery Manual (IDM), apresenta-se como essas informações podem ser mapeadas e qual o subconjunto de dados necessários à fabricação digital baseada no esquema IFC4. Por fim, apresenta-se a documentação e validação da solução técnica desenvolvida de acordo com o método Model View Definition (MVD) e com o uso da ferramenta ifcDoc. Após a realização de testes com base no esquema IFC4 foi constatada a viabilidade para recuperação dos dados contidos no modelo. Entretanto também foi identificada a carência de ferramentas comerciais que suportem tal funcionalidade. / The consolidation of Building Information Modeling (BIM) possibly contributes to the increase of the efficiency in the construction industry, by fostering new workflows and data reuse throughout projects life cycle. Despite the potential for integration and automation associated with BIM, the use of the digital information contained in the model to facilitate prefabrication of construction products is still incipient. The digital fabrication finds obstacles in sectors that act in a segregated manner, henceforth needs standard adoption to allow reuse of the information generated in the phases prior to production. In this context, it was analyzed the use of digital fabrication applied to the industrial processing of reinforcement bars for concrete structures (rebar cutting and bending). Although the fabricators who act in this sector already have support to the digital interface with other agents, the supply chain configuration adopted by the Brazilian market, as well as the traditional paper-based processes employed, promote the occurrence of \"islands of automation\" connected by manual data transfer. In order to reduce the need for manual intervention for data re-interpretation and re-entry, it is proposed to use the Industry Foundation Classes (IFC) data schema to promote the digital interface between the reinforcing bar supply chain stakeholder\'s. This work aims to present an IFC-based technical solution to the fabricator\'s information requirements by means of the Information Delivery Manual (IDM) and Model View Definition (MVD) standards. On the basis of the exchange requirements specified by rebar fabricator through IDM method, it is presented the IFC schema subset entailed and how this information can be mapped in order to allow the use of IFC on the cut & bend rebar supply chain. Finally, the technical solution was documented in an MVD and validate with the ifcDoc tool. After conducting validation tests based on the IFC4 schema, it was verified the viability to recover the data contained in the model. However, the lack of commercial tools that support such functionality has also been identified.

Projeto e construção de um dispositivo para ensaio de impacto em materiais, barra de compressão / Design and construction of a device for impact test materials, compression bar

Todesco, Sérgio Roberto 17 November 2015 (has links)
Esta dissertação apresenta um projeto de um dispositivo para levantar dados característicos de materiais submetidos às altas taxas de deformação, dispositivo este que leva o nome do seu idealizador o engenheiro Inglês Sir Bertram Hopkinson. Mais especificamente, esta dissertação está inseparavelmente ligada ao desenvolvimento de um embalado para transporte de elementos radioativos como sendo uma das partes do escopo geral, de um projeto da CAPES em convênio com o Centro de Ciência e Tecnologia de Materiais - CCTM do, Instituto de Pesquisas Energéticas e Nucleares IPEN - CNEN/SP, autarquia associada à Universidade de São Paulo. O desenvolvimento do dispositivo faz parte do escopo de obtenção, e levantamento dos dados necessários para o projeto, e a construção do embalado. Esta dissertação versa sobre a concepção mecânica do dispositivo, importante, dividida em duas partes, dimensionamento das barras, que seriam a barra de impacto, a barra de entrada, e a barra de saída, e o dimensionamento do dispositivo de impacto. O dimensionamento das barras envolve conhecimentos do conceito de ondas elásticas em meios sólidos para que o comprimento das barras seja estimado de forma a servir de guia das ondas elásticas, que provocarão a deformação no corpo de prova, e possibilite a boa leitura dessas ondas para análise dos dados. O dispositivo de impacto, este tem que ser robusto o suficiente para produzir a onda de tensão que deforme o corpo de prova, mas não para deformar plasticamente as barras, que terão que continuar durante todo o teste dentro do regime elástico. / This dissertation presents a design of a device to collect characteristic data of materials submitted to the high strain rates, device that takes the name of its idealizer the English engineer Sir Bertram Hopkinson. More specifically, this dissertation is inseparably linked to the development of a package for the transport of radioactive elements as part of the general scope of a CAPES project in partnership with the Materials Science and Technology Center (CCTM), Nuclear and Energy Research Institute IPEN - CNEN / SP, autarchy associated with the University of São Paulo. The development of the device is part of the scope of procurement, and collection of data required for the design, and the construction of the packaging. This dissertation deals with the mechanical design of the device, important, divided into two parts, dimensioning of the bars, which would be the impact bar, the input and output bars and the design of the impact device. The sizing of the bars involves knowledge of the concept of elastic waves in solid media so that the length of the bars is estimated in order to serve as a guide for the elastic waves, which will cause deformation in the test body, and enable a good reading of these waves for analysis of the data. The impact device has to be robust enough to produce the stress wave that deforms the test body but not to deform the bars plastically, which will have to continue throughout the test within the elastic regime.

Comparison Between Confidence Intervals of Multiple Linear Regression Model with or without Constraints

Tao, Jinxin 27 April 2017 (has links)
Regression analysis is one of the most applied statistical techniques. The sta- tistical inference of a linear regression model with a monotone constraint had been discussed in early analysis. A natural question arises when it comes to the difference between the cases of with and without the constraint. Although the comparison be- tween confidence intervals of linear regression models with and without restriction for one predictor variable had been considered, this discussion for multiple regres- sion is required. In this thesis, I discuss the comparison of the confidence intervals between a multiple linear regression model with and without constraints.

Inference in Constrained Linear Regression

Chen, Xinyu 27 April 2017 (has links)
Regression analyses constitutes an important part of the statistical inference and has great applications in many areas. In some applications, we strongly believe that the regression function changes monotonically with some or all of the predictor variables in a region of interest. Deriving analyses under such constraints will be an enormous task. In this work, the restricted prediction interval for the mean of the regression function is constructed when two predictors are present. I use a modified likelihood ratio test (LRT) to construct prediction intervals.

Estudo da evolução do tamanho de grão na laminação a quente de barras de aço médio carbono microligado ao vanádio - 38MnSiV5. / Grain size evolution of a vanadium microalloyed steel during bar rolling mill - 38MnSiV5.

Silvério, Valdir Anderson 20 March 2008 (has links)
Os aços microligados ao vanádio são usados em peças automotivas forjadas, tais como virabrequins e bielas. Através de equações matemáticas que descrevem a cinética de recristalização e de crescimento de grão, foi desenvolvida uma rotina em planilha para simular a evolução dos tamanhos de grão austeníticos durante os passes de laminação em função da temperatura, taxa de deformação, tempo entre passes e características do material. O resultado do tamanho de grão ferrítico calculado final, foi comparado com os tamanhos de grãos de amostras retiradas da laminação e de amostras realizadas por simulação física (ensaio de torção a quente). Esta comparação entre modelamento matemático e simulação física com o processo de laminação, demonstra que é possível calcular e descrever a evolução microestrutural e mostra que o principal mecanismo de controle do refino de grão envolvido em uma laminação de não planos com trens abertos é o de recristalização estática, para as condições existentes na usina onde foi efetuado o presente estudo. / Microalloyed steels are used as forging stock for many automotive parts such as crankshafts and connecting rods. Using mathematical equations describing the recrystallization kinetics and grain growth, a spreadsheet has been developed to simulate the austenitic grain size evolution during bar rolling mill schedules as a function of temperature, strain rate and time between passes. The calculated ferritic grain size was compared with samples taken from the process and physical simulation (torsion testing). Comparison between mathematical modeling and physical simulation with the plant bar rolling mill process shows that it is possible to predict the microstructural evolution and confirm the main grain refinement control mechanism as being static recrystallization, under the conditions prevailing in the plant where this study has been carried out.

Examination of Bar Velocity in Barbell Back Squat

Sato, Kimitake, Carroll, Kevin M., Stone, Michael H. 01 July 2016 (has links)
The aim of the study was to examine repetition to repetition changes of bar velocity and its variations from barbell back squat. Participants (N=19) performed back squat with a relative intensity of 78-80% of 1 RM. Bar velocity was captured using wireless device (PUSHtm) placed on their forearm. Data were collected from 3 sets of 10 repetitions. One-way repeated measures ANOVA was used to identify the velocity changes over 10 repetitions. Statistical significance was found (F(1,17)=45.06.~ 0 . 0 0 0 1 )T.h is indicates that the bar velocity decreased significantly over the 10 repetitions. At the same time, coefficient of variance also increased as the repetitions went higher, indicating that there were differences in individual responses of bar velocity changes. Further examination will be aimed to investigate the bar velocity changes from various strength level of individuals.

Improving the Nursing Practice Environment With Point of Care Specimen Collection

Saathoff, April Marie 01 January 2017 (has links)
Specimen collection and identification errors are a significant problem in healthcare, contributing to incorrect diagnoses, delayed care, lack of essential treatments, patient injury or death, increased length of stay and increased healthcare costs, and decreased patient satisfaction. The purpose of the project was to evaluate the implementation of specimen collection technology with barcode scanning and bedside label printing in the maternal child health division of a community teaching hospital. The project was driven from Donabedian's quality framework for healthcare implementations, indicating that evaluating the quality of health care can be drawn from the categories of structure, process, and outcomes. The project featured a quantitative analysis with a pretest-posttest design. Mislabeled specimen rates and collection turnaround times were generated from laboratory quality data and measured before, during, and after implementation of specimen collection technology. Data analysis using an independent samples t test in SPSS 17.0 compared the changes in the mean scores of specimen collection turnaround times and mislabeled specimen rates. Mislabeled specimen percentages in all areas decreased from 0.0250% preimplementation to 0.0023% postimplementation with a p value less than 0.001. Collection turnaround times greater than 60 minutes decreased following implementation of specimen collection technology by 22% with a p value less than 0.001. The implementation of specimen collection technology has positive implications for social change, including the expectation that as technology is proven to significantly improve the safety and quality of laboratory collections, there will be a mandate for implementation of safer collection processes in healthcare.
