BACKGROUND Personality traits associated with one's health beliefs and expectations constitute a determinant of dietary behaviours. OBJECTIVE The aim of the study was to analyse the dietary behaviours of young American football players in the Polish clubs and association thereof with their general self-efficacy level. MATERIALS AND METHODS The study included the group of 100 young men (20-3...

In the society, science and technology are intimately linked to the studies and expansion in the general progression of the society. However, the Indigenous Knowledge (IK) which holds the same weight-age as the development of the society with science seems to be forgotten. IK is a knowledge that being used by the people in certain environments in making their living such as health, spiritual an...

We discuss the advantages of wavefront sensing at near-infrared (IR) wavelengths with low-noise detector technologies that have recently become available. In this paper, we consider low order sensing with laser guide star (LGS) adaptive optics (AO) and high order sensing with natural guide star (NGS) AO. We then turn to the application of near-IR sensing with the W. M. Keck Observatory (WMKO) A...

OBJECTIVES This study aimed to evaluate the food intake patterns of adolescents with respect to the Australian Guide to Healthy Eating, and to examine variations in food intake patterns by age, gender and region of residence. DESIGN Cross-sectional online food survey administered through schools. PARTICIPANTS AND SETTING In 2004-2005, 3841 secondary students in years seven (12-13 years) and...

We consider the number of trophic levels in a food chain given by the equilibrium state for a simple mathematical model with ordinary differential equations which govern the temporal variation of the energy reserve in each trophic level. When a new trophic level invades over the top of the chain, the chain could lengthen by one trophic level. We can derive the condition that such lengthening co...

OBJECTIVE To assess food intake and meal patterns in adolescents, a cross-sectional study was conducted with 228 adolescents from a public school, SP, Brazil. METHODS Total energy, macronutrients, calcium, iron, and vitamin A intakes were evaluated. The food pattern was compared with the eating patterns established by the Food Pyramid for adolescents. Meal frequency was assessed to identify m...
