OBJECTIVES This study investigated the importance of environmental influences in explaining weight gain and related behaviors among freshman college students. METHODS We exploited a natural experiment that takes place on most college campuses in the United States--randomized dormitory assignments. We estimated the effects of living in dormitories with varying physical environment characterist...

Grain quality currently represents a major problem in high yielding rice production in Iran and many other rice producing areas of the world. Quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. These research genetic materials we...

It is unclear if children of different weight status differ in their nutritional habits while watching television. The objective of the present paper was to determine if children who are overweight or obese differ in their frequency of consumption of six food items while watching television compared with their normal-weight counterparts. A cross-sectional study of 550 children (57·1 % female; m...

Aim: The aim of the present study was to investigate antioxidant effect aqueous leaves extract Anacardium occidentale (A.O) on lead-induced toxicity in cerebellum wistar rats.
 Methods: Thirty rats were randomly divided into six groups five each. Group A: Normal control received 0.5ml normal saline; group B 50mg/kg body weight (bwt) lead acetate (Pb) only (28 days); C and D: 150mg/kg bwt 3...

Cyclic codes of dimension 2 over a finite field are shown to have at most two nonzero weights. This extends a construction of Rao et al (2010) and disproves a conjecture of Schmidt-White (2002). We compute their weight distribution, and give a condition on the roots of their check polynomials for them to be MDS.
