objectives: to compare bmi and inverted bmi in evaluating body measurement, resting blood pressure, dual energy x-ray absorptiometry (dexa) parameters of fat mass and metabolic risk factors in iranian children materials and methods: this is a cross-sectional study on 477 children aged 9-18 yearsin the south of iran. weight, height, resting blood pressure, waist and hip circumference and puberta...

wall displacements and ground pressure acting on the lining of a tunnel increase with time. these time-dependent deformations are both due to face advance effect and to the time-dependent behavior of the rock mass.  viscoelastic materials exhibit both viscous and elastic behaviors. thorough this study, the effect of different linear viscoelastic models including maxwell, kelvin and kelvin-voigt...

Background and aims: Obesity and overweight is a major public health problem and, alongside hypertension, is one of the risk factors of cardiovascular diseases incidence. The aim of this study was to determine the prevalence of overweight and its association with hypertension in the patients referred the healthcare center in Jandaq. Methods: This cross-se...

the pressure drop of refrigerant r-134a flow boiling inside a horizontal tube has been investigated experimentally. the test set-up which was used in this investigation is a well instrumented vapor compression refrigeration system. these instruments are thermocouples, flow meter, pressure gauges and the pressure drop measuring apparatus. this system consisted of three electrically heated evapor...

Purpose: The aim of this study was to compare biochemical tests, body composition and anthropometric parameters in Nonalcoholic Fatty Liver Disease (NAFLD) patients before and after Ramadan fasting. Methods: fifty NAFLD patients including 33 males and 17 females aged 18-65 year, were recruited. Subjects attended after diagnosis based on  ultrasound imaging, with at least 10 hour fasting, before...

Diffuse leptomeningeal glioneuronal tumor is characterized by hydrocephalus, leptomeningeal involvement in the absence of a primary parenchymal mass, and negative cerebrospinal fluid (CSF) cytology. It is an extremely rare and difficult tumor to diagnose as no mass can be biopsied and it mimics infectious, rheumatologic, and inflammatory pathologies. An 11-year-old girl presented with complaint...

In the present paper, the effect of water-CuO nanofluid on the radiator heat transfer of an automobile, Peugeot 405 XU7 engine type is investigated experimentally. The experiments are carried out for the radiator water (water-ethylene glycol with a volume fraction of 80-20, respectively) as a base fluid and water-CuO nanofluid with the volume fraction of 0.5% and 1%. Sodium Dodecyl Sulfate (SDS...
