Introdução. O transporte é um procedimento crítico na manutenção da cadeia do frio do sangue. Falhas neste procedimento podem comprometer a sua qualidade e a segurança transfusional. Objetivo. Avaliar as não conformidades (NC) do Hemocentro de Ribeirão Preto relacionadas ao transporte de concentrado de hemácias (CH). Analisar caixas térmicas e gelos recicláveis submetidos à temperatura de 20°C e 30°C e propor melhorias neste processo. Métodologia. Estudo retrospectivo de NC relacionadas ao transporte de CH no software do sistema da qualidade do Hemocentro de Ribeirão Preto e pesquisa experimental realizada com três caixas diferentes em combinação com três gelos recicláveis distintos, simulando uma situação de transporte, nas temperaturas externas de 20°C e 30°C. Realizou-se uma estatística descritiva com os dados. Utilizou-se a metodologia de análise de variância (ANOVA), com o auxílio do software SAS® 9, utilizando a PROC GLM. Para as comparações foram utilizados contrastes ortogonais baseados na distribuição t. Resultados. Os resultados mostraram diferenças significativas no desempenho entre as caixas e entre os gelos recicláveis. No entanto, as maiores diferenças ocorreram entre as temperaturas externas de 20°C e 30°C, indicando a interferência da temperatura externa na temperatura do conteúdo interno. Outra diferença encontrada foi entre pontos de aferição das temperaturas, dentro da mesma caixa, indicando que a distribuição do ar, no interior da caixa não é homogênea. Conclusão. São vários os interferentes existentes durante o transporte de CH, que podem comprometer a qualidade do sangue. O transporte deve ser validado, padronizando o maior número de variáveis possíveis, para minimizar as adversidades que ocorrem durante o procedimento / Introduction. The transport is a critical procedure in the maintenance of the blood cold chain. Failures in this procedure can compromise the blood quality and transfusion safety. Purpose: Evaluate the non-conformances (NC) of Hemocentro de Ribeirão Preto related to the Red Blood Cell (RBC) transport. Verify coolers, recycle ice at a temperature of 20°C and 30°C and propose improvements in this process. Methodology: Retrospective study of NC related to RBC transport in Hemocentro de Ribeirão Preto quality system software. Experimental research performed with three different insulated boxes combined with three different ice packs, simulating a situation of transport in the external temperatures of 20°C and 30°C. It was made a descriptive statistic of the data. The methodology of analysis of variance was used, through the software SAS® 9, using a PROC GLM. To do the comparisons orthogonal contrasts based on t distribution were used. Results: The results shown significant differences between insulated box and ice packs. However, the larger differences occurred between the temperatures of 20°C and 30°C, indicating that the external temperature interfere in the temperature inside the box. Another difference found was between points of temperature, inside the same insulated box, indicating that the air distribution inside the insulated box is not homogeneous. Conclusion. During RBC transport, many interfering exist that can compromise the blood quality. The transport must be validated, standardizing the largest number of details that is possible, to minimize adversity that occur during the procedure

The field of a research of this diploma thesis is building with controlled internal temperature. The research is focused on main heat fluxes at this type of buildings and how it contributes to the energy consumption of the building. The main objective of the analysis is heat loss caused by heat flux through the building envelope and air exchange at the building. As next it is described heat gain resulting from the operation inside of the building. To obtain the results of the research part is used software on the platform Delphi Pascal, temporarily called SIM_Chlad. The aim of this computer modeling is non-stationary heat fluxes from the mentioned heat sources in the building. The computed heat balance analyzes the energy consumption of the building for a period of one year. The diploma thesis evaluates impacts reflecting local weather conditions, the structural system of the building and the operation in the building. A cooling machinery analysis is not the subject of the research at this diploma thesis.

<p>This work focuses on the collection and analysis of Lithium-ion battery operational and temperature data during nail penetration testing through two different experimental approaches. Raman spectroscopy, machine learning, and internal temperature sensors are used to collect and analyze data to further investigate the effects on cell operation during and after nail penetrations, and the feasibility of using this data to predict future performance.</p> <p><br></p> <p>The first section of this work analyzes the effects on continued operation of a small Lithium-ion prismatic cell after nail penetration. Raman spectroscopy is used to examine the effects on the anode and cathode materials of cells that are cycled for different amounts of time after a nail puncture. Incremental capacity analysis is then used to corroborate the findings from the Raman analysis. The study finds that the operational capacity and lifetime of cells is greatly reduced due to the accelerated degradation caused by loss of material, uneven current distribution, and exposure to atmosphere. This leads into the study of using the magnitude and corresponding voltage of incremental capacity peaks after nail puncture to forecast the operation of damaged cells. A Gaussian process regression is used to predict discharge capacity of different cells that experience the same type of nail puncture. The results from this study show that the method is capable of making accurate predictions of cell discharge capacity even with the higher rate of variance in operation after nail puncture, showing the method of prediction has the potential to be implemented in devices such as battery management systems.</p> <p><br></p> <p>The second section of this work proposes a method of inserting temperature sensors into commercially-available cylindrical cells to directly obtain internal temperature readings. Characterization tests are used to determine the effect on the operability of the modified cells after the sensors are inserted, and lifetime cycle testing is implemented to determine the long-term effects on cell performance. The results show the sensor insertion causes a small reduction in operational performance, and lifetime cycle testing shows the cells can operate near their optimal output for approximately 100-150 cycles. Modified cells are then used to monitor internal temperatures during nail penetration tests and how the amount of aging affects the temperature response. The results show that more aging in a cell causes higher temperatures during nail puncture, as well as a larger difference between internal and external temperatures, due mostly to the larger contribution of Joule heating caused by increased internal resistance.</p>
