This paper applies a recently developed immersed boundary-turbulence wall modeling approach to turbulent flows over generic car geometry, known as the Ahmed body, under massive flow separation within lattice Boltzmann solver. Although boundary method combined with hierarchical Cartesian grid offers high flexibility in automatic generation around complex geometries, near-wall solution is signifi...

background : in recent years tissue engineering developed to replace or repair damaged tissues using cell and biomaterial. one of the most important fields of tissue engineering is simulation of in vivo micro environment of body tissues. this study aimed to develop culture chamber and cell biomaterial sheet engineering for the reconstruction of cartilage tissue. methods : stainless steel cultur...

The palatability of various organs (body wall, cuvierian gland, viscera, longitudinal muscle bands and gonads) of sea cucumber Holothuria leucospilota (Brandt) was studied by feeding experiments, performed on a freshwater fish Sarotherodon mossambicus and a marine fish Theraponjarbua. The result shows that the food pellets of the body wall were less toxic and more palatable than the gonads, vis...

M-mode echocardiography was used to estimate left ventricular wall mass in 136 older normal subjects (Group I: 78 men and 58 women, ages 20 to 97 years) and 105 younger normal subjects (Group II: 52 male and 53 female subjects, ages 1 day to 23 years). Echocardiographic left ventricular mass (in grams) was estimated from the following formula: left ventricular mass = 1.05 ([ left ventricular in...

Leptin, the product of the ob gene, has been shown to increase heart rate and blood pressure through a stimulation of cardiac sympathetic nervous system activity, a phenomenon also involved in the pathogenesis of left ventricular hypertrophy in hypertensives. Thus, we hypothesize that plasma leptin concentration is associated with left ventricular hypertrophy. Forty hypertensive males and 15 he...

BACKGROUND Restriction in fetal growth is associated with cardiovascular disease in adulthood. It is unclear whether abnormal intrauterine growth influences arterial morphology during the fetal or neonatal stage. The objective was to study the regional arterial morphology with respect to gestational age and abnormal fetal body size. METHODS AND RESULTS We studied body anthropometrics and arte...

background & aim:  the aim of this study was to evaluate and compare the relationship between body image and quality of life in female patients with breast cancer and healthy women. methods:in the current descriptive, causal, comparative, cross-sectional study, 50 women with breast cancer, referring to the radiotherapy and oncology clinic of imam reza hospital (mashhad, iran) and 50 healthy wom...
