The obesity has become a growing threat to the population of the world wich come from a lot of health problems are faced by individuals. This study aims to evaluate the quality of life is related to health (HRQOL) of individuals six months before and after their participation into a loss weight program. The study was observational, descriptive, exploratory, prospective with quantitative approach made in the first aid room of specialities of the Hospital of the Federal University of Sergipe from May 2015 to May 2016. The sample was not probabilistic type because the convenience wich was composed by 35 patients. The Data collection was made through a questionnaire about sociodemographic clinical information, besides the tools Item Short Form Health Survey (SF-36) and Impact Of Weigth On Quality Of Life-Lite (IWQOL-Lite), which evaluates the quality of life is related to general health and specific weight reduction, respectively. The Data were analyzed using simple statistics and tests such as Chi-square test, Fisher exact test, Student's t and Wilcoxon, considering the statistical significance of 5% (p <0.05). The average age was 42 years. The Patients were predominantly female, most of them live in large Aracaju with color skin is not white, until two minimum wages, low education level and without a steady partner. About the evaluation of the segment, 77.1% of the patients reduced weight, 5.7% lost enough to modify the obesity class. There was a significant association between the blood pressure level before and after their insertion in the program. The generic instrument showed in evaluation of the pre-insertion in the program, positive and significant correlations of some areas with the variables sex, skin color, education and physical activity. The Comorbidities and body mass index (BMI) showed significant correlations, although negative for emotional aspects. It is added to the comorbid correlations with functional capacity and physical social aspects. In the evaluation after insertion, the gender and physical activity were associated with all areas. Regarding physical activity, the exceptions were the domain general health, social aspects and mental health. Comorbidities and BMI were negatively correlated with functional capacity as well as physical aspects and mental health, respectively. The specific instrument showed in the evaluation of pre-insertion significant correlation of some variables, however physical activity was highlighted witch showed significant positive correlation with all areas, except the area sex. There were negative correlations between the comorbidities with the aspect work, weight with difficult in public places and also in work, moreover the BMI with every aspects, except the self-esteem. In the evaluate after the participation, the variables education level, sex and physical activity were correlated with the most of domain. It is occured negative correlation between comorbidity the sexual life, weight and MBI, with difficult in public places. Therefore, the loss weight was significant in the reduction of the blood pressure levels. The high education level, gender and physical activity were the factors that interfere in the HRQOL of patients. / A obesidade tornou-se uma ameaça crescente para a população mundial e dessa, provém vários problemas de saúde enfrentados pelos indivíduos.

Simulation-based design optimization and finite element method are used in this research to investigate weight reduction of car body structures made of metallic and composite materials under different design criteria. Besides crashworthiness in full frontal, offset frontal, and side impact scenarios, vibration frequencies, static stiffness, and joint rigidity are also considered. Energy absorption at the component level is used to study the effectiveness of carbon fiber reinforced polymer (CFRP) composite material with consideration of different failure criteria. A global-local design strategy is introduced and applied to multi-objective optimization of car body structures with CFRP components. Multiple example problems involving the analysis of full-vehicle crash and body-in-white models are used to examine the effect of material substitution and the choice of design criteria on weight reduction. The results of this study show that car body structures that are optimized for crashworthiness alone may not meet the vibration criterion. Moreover, optimized car body structures with CFRP components can be lighter with superior crashworthiness than the baseline and optimized metallic structures.

The intention of this thesis is to develop, evaluate new concepts and look over the current design for a container sized barge module. By request of Group Ocean, a cost and weight reduction is the main improvement criteria along with keeping the strength of the module.Five concepts are developed, analyzed and discussed with the supervisor at Group Ocean, where three are decided to be presented here. The other two are left out, since they are considered way too expensive without giving a satisfying result. The three concepts that are developed throughout this thesis are; changing to high strength steel, changing to sandwich panels and increasing stiffeners with smaller dimensions.A structural optimization is made in the software MATLAB to find out the best dimension to use for the sandwich panels. To determine the local stresses, the finite element method is used in Inventor Professional. It is also where the design and CAD modules are built in, so for simplifications it is used for FEA (Finite Element Analysis) as well. To reduce the amount of elements and nodes, shell elements and other structural constraints are used in the FEA. All the concepts are modelled with the same structural constraints so a practical comparison study can be made.The final designs resulted in a total weight reduction up to 40% with a material cost reduction of 12%. Based on what type of material is chosen, the material cost reduction range is between 3-12% and the weight reduction range is between 13-40%.

Weight loss maintenance and emotional and physical problems were investigated in subjects on a protein-sparing modified fast. Four months following a weight reduction program using the protein-sparing modified fast, twenty of the forty-two subjects were contacted. Each was asked to complete a questionnaire related to emotional and physical effects of the diet and a diet history checksheet. Each subject was weighed to determine if weight loss had been maintained. Results of the questionnaire, diet history, and blood chemistry analysis indicate that for these subjects, the modified fast may be safe and effective in reducing and maintaining weight loss over a short time period under close supervision by a physician.

Continuous improvements are an integral part for the development of everyday life. These improvements do not only ascertain financial gain but also lessening the environmental impact. The purpose of this study is to gain a deeper understanding of the design process and the decisions required to achieve an optimal design with respect to weight reduction, while retaining the required strength. The study will also investigate the choice of material. This will be done through material and design studies, along with strength calculations of the product in question. The conclusion from this study is that it is possible to save a certain percentage of the material used, while keeping the strength, form, fit and function intact. The material study provided with a recommendation of the zinc alloy ZA-8. It is an alloy with a good combination of great strength, low density and price.

Dans l’industrie automobile, le véhicule électrique séduit de plus en plus de clients. Ce qui limite sa progression dans le marché est son manque d’autonomie. Une des solutions permettant d’augmenter l’autonomie d’un véhicule est de réduire sa masse en modifiant la géométrie des pièces et les matériaux utilisés. Cependant, de tels changements peuvent avoir des impacts sur la CEM du véhicule.Les travaux de cette thèse portent sur l’étude de l’allègement du blindage des batteries de traction pour véhicule électrique du point de vue de la CEM. Plusieurs méthodes de caractérisation de matériaux sont mises en place dans ce document. Une méthode innovante reposant sur l’utilisation d’une cellule TEM ou d’une stripline a été développée durant ces travaux de thèse, elle permet de mesurer la permittivité relative complexe d’un matériau diélectrique inconnu entre 1 kHz et 1 GHz. Les propriétés électromagnétiques ainsi mesurées sont insérées dans des modèles numériques 3D. Les méthodes numériques adaptées à ce type d’étude sont les différences finies dans le domaine temporel et la méthode des moments. L’étude du rayonnement de la batterie a été effectuée grâce à une maquette à l’échelle ½ en chambre semi-anéchoïque et en chambre réverbérante à brassage de mode selon des montages normatifs. Des configurations plus complexes ont ensuite été étudiées en tenant compte de l’intégration du pack-batterie dans le véhicule. / In automotive industry, electric vehicle is becoming more and more attractive for car buyers. The market penetration of electric vehicle is limited by its short range. One of the solutions to increase the range is to lower the weight of the vehicle by modifying the geometry or the material composition. Nevertheless, such changes may have consequences on the EMC of the vehicle.The work of this thesis concern the study of weight reduction of the battery shield from an EMC point of view. Several methods for materials characterization are set in this document. A method which uses a TEM cell or a stripline has been designed during this thesis to measure the complex relative permittivity of an unknown dielectric material. Then, the measured properties are inserted into numerical 3D models. The numerical techniques that fit this study are the finite differences in time domain and the method of moments. The study of radiated electromagnetic field from a battery has been performed thanks to a ½ scale model in semi anechoic chamber and mode-stirred reverberation chamber according to standard setups. More complex configurations were studied taking into account the integration of the battery-pack into the vehicle.

This thesis has been carried out together with Kalmar Global’s Innovation Center and covers a concept study about weight reduction of the telescopic boom of the Reachstacker DRG 450.The reason for this weight reduction is to ease Kalmar’s transition from fossil fueled to electric driven vehicles since less weight reduces energy consumption and leaves more room for batteries. The main focus of the study is to test a wide array of cross sections for the boom with the aim of weight saving. During the thesis both meshless and traditional finite element calculations are used when utilising simulation-driven design to optimise the boom. The study concludes that using a narrower octagonal cross section, improved material quality and adapting the positions of the mounts can decrease the weight by 23% with also decreasing the material cost by 13%.
