the role of the ventromedial nuclei of the hypothalamus (vmn) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. electrolytic lesions were induced stereotaxically (1.2 ma, 15 sec). results revealed a significant decrease (p

the starting behavior of a supersonic axisymmetric mixed compression air intake was numerically investigated. the code solves reynolds-averaged navier–stokes equations using an explicit finite volume method in a structured grid by the roe flux difference splitting scheme. further, it uses the baldwin–lomax algebraic model to compute the turbulent viscosity coefficient. the correct method of sur...

introduction: the relative costs of generating energy vary considerably depending on location. since hospital managers confront serious financial problems, they need to look for ways to use energy more efficiently. this study aimed to study the rate of energy use (water, gas and electricity) in a number of hospitals in isfahan from 1378 to 1382 and to compare the results with the available stan...

conclusions due to seasonal variations in fruit and vegetable dietary intakes, the interventional and case-control studies should consider seasonality. educational and price controlling programs may control such observed seasonality in the intake of fruit and vegetables. results the highest consumption of vegetables was seen in summer (289 ± 3.4 g/day) while the lowest was in winter (224 ± 3.2 ...

one of the causes of perturbation at vertical intakes is the happening of vortices with an air core. the vortices with an air core occur whenever the submergence of the intake is less than a critical value. anti-vortex devices and specially plates are used to avoid the negative effects of the air-core vortices. if plates are used, then the geometry of them should be studied experimentally. acco...

this study was aimed to evaluate the effects of diets containing some hot and coldtemperament herb seeds according to iranian traditional medicine (itm) on some metabolicparameters in acute (24 h) and sub-acute (7 day) experiments that were performed on rats. foreach experiment, effects of diets containing 10% herb seeds in category of hot (anise, fennel,ajowan) and cold (cucumber, watermelon, ...

organochlorine and organophosphate pesticides are likely to pollute lipid-containing food sources, like milk (3-5% fat), owing to their lipophilicity, thereby jeopardizing the benefits of milk as a health food. pesticide load in bovine milk may be from the leaching of pesticides persisting in the adipose tissue of the animal, or through direct contamination during milking or improper handling o...

nutritional status during adolescence plays an important role in human lifecycle. the aim of this study was nutritional status and dietary intake among adolescent girls. in a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 semnan secondary schools. weight and height were measured and body mass index (bmi) was calculated. in adolescents,...
