Režimová opatření k ovlivnění nadváhy nebo obezity u žen / Lifestyle changes affecting the overweight or obese women

Václavík, Pavel January 2014 (has links)
Title: Lifestyle changes affecting the overweight or obese women Objective: The aim of our investigation will determine whether through physical activity and eating habits can positively affect body weight reduction in adult women with overweight and obesity. This work would also like to draw attention to eating a mostly physical habits that may not be enough , and I would also like to point out how women are familiar with this issue . Methods: To get all the data has been recovered poll list , which consists of 22 questions selected and which lasted for one month . The main task is to compare the physical and dietary habits among adult women with normal weight women and overweight and obesity. Filling in the poll list that I created on the site vyplnto.cz was completely anonymous . This could be posted to the most objective answers. Results: From the research we have confirmed all three hypotheses . We can say that women who are overweight and obese have higher energy intensity than women with normal weight , because often consume inappropriate foods that are energy rich . Regularity Boarding is at a better level in women with normal weight . Women who are overweight and obese have an exercise regimen with a lower volume than women with normal weight . Effects of physical activity and eating...

Development of photoinitiating systems for free radical Photopolymerization usable for laser Imaging / Développement des systèmes photoamorceurs pour imagerie laser

Ibrahim, Ahmad 07 October 2011 (has links)
Le sujet de thèse sur lequel je travaille depuis trois ans est l’étude et le développement des systèmes photoamorceurs pour des applications holographiques. Ce travail a lieu en collaboration avec l’équipe BMS (Bayer Material Science) de Bayer-Leverkusen (Allemagne). Mes études se sont limitées aux systèmes utilisables avec une source d’irradiation appartenant à la partie visible du spectre électromagnétique de la lumière (400 nm – 700 nm).Parmi les différents types des réactions de polymérisation, nous avons choisi la polymérisation radicalaire. L’étape cruciale dans cette réaction réside dans la génération des radicaux qui amorcent la réaction. Ces derniers sont formés par transformation, via absorption de lumière, d’un composé photosensible. La formation de ces espèces est en général en compétition avec plusieurs processus de désactivation. Les polymérisations radicalaires sont en particulier fortement inhibées par l’oxygène de l’air. Pour réduire l’effet de l’oxygène et pour avoir des conditions comparables à ceux appliqués dans l’industrie, nos échantillons ont été préparés en utilisant la technique laminée (l’échantillon est mis entre deux films de polypropylène).

These are formed by transformation via absorption of light of a photosensitive compound. The formation of these species is generally in competition with several deactivation process. [...]
