Restdts showed that enhanced UV-B radiation significantly inhibited ingesting of the rotifer B. urceus when it was fed with 5 species of micro-algae (p〈0.05). The ingesting selectivity rate varied with the UV-B radiation enhancement when it was fed with 5 species micro-algal mixture. Results indicated that the enhanced UV-B radiation could affect ingesting and nutritional selectivity of B. urceus.展开更多

However, many obstacles such as poor financial support, lack of time and poor nutritional knowledge can influence achievement of optimal nutrition which is proportional to the level of the athlete's physical activity. The purpose of this study was to determine the level of nutritional knowledge and dietary behavior of athletes in Khorramabad in 2013. Professional athletes of Khorramabad, Iran, with more than one year of regular exercise and at least one course participating in national championships competitions were studied in this cross-sectional, descriptive-analytic study. The samples included 247 athletes aged 17-29 years. Their nutritional knowledge and behavior were measured by the nutritional knowledge and behavior inventory. Results: The results showed a significant difference in nutritional knowledge of athletes by gender and educational level; female athletes have higher nutritional knowledge than male athletes. A gender-dependent difference was found in nutritional behavior; despite their higher nutritional knowledge, female athletes have weaker nutritional behavior than male athletes. However, no significant correlation was found between BMI and nutritional knowledge and behavior of the athletes. Moreover, findings showed that nutritional knowledge and behavior could be significantly different in various sports.展开更多

The Date Palm (Phoenix dactylifera) has known some kind of specificity in its different life phases, compared to all the rest of oases cultivate plants. It is thanks to that person could settle down. A study within a ministerial research project about the date palm variety in the previous areas has shown that there are 400 spices of dates. Thanks to this diversification types, members of this community were able to acquire experience in the field of the uses of date in their nutritional behaviour. Harvest begins from precocious summer's soft date variety in June, as in the late autumn variety in October. In addition, there are different type of the date: wet, semi-wet and dry date. For each variety, there is a particular method of its use. It is an example of sustainable food, is the one present in all oasis occasions. The aim of the current study was to examine the different methods of nutritional ate uses, in Touat, Gourara and Tidikelt, by its inhabitants, and to show the local skills sustained across the generations.展开更多
