In order to prevent unpleasant incidents, preservation high-speed railway vehicle stability has vital importance. For this purpose, railway vehicle is modeled using a 38-DOF. This paper presents an investigation on limit cycle and bifurcation of high speed railway behavior. It is revealed that the critical hunting speed decreases by increasing the wheel conicity. Also the critical hunting speed...

BACKGROUND Left ventricular size and shape are important for quantifying cardiac remodeling in response to cardiovascular disease. Geometric remodeling indices have been shown to have prognostic value in predicting adverse events in the clinical literature, but these often describe interrelated shape changes. We developed a novel method for deriving orthogonal remodeling components directly fro...

The pattern of fat distribution is related to a large number of variables of clinical importance. Many anthropometric indices have been derived which are surrogate measures of central fat distribution. However, systematic information on age variations in regional adiposity and central fat distribution is incomplete. The present study investigates the age variations in regional adiposity and fiv...

BACKGROUND The association between obesity and blood pressure is well documented and a series of obesity indices are used as risk factors or indicators of blood pressure and/or the presence of hypertension. OBJECTIVE The aim of the present study was to explore and determine which obesity index is the best indicator of blood pressure and the presence of hypertension among five frequently used ...

CONTEXT AND OBJECTIVES Early detection of reduced insulin sensitivity (IS) and insulin resistance (IR) is desirable. The aim here was to evaluate correlations of anthropometric indicators for identifying IR or IS and determine the cutoff points of the most effective indicators. DESIGN AND SETTING Cross-sectional study in the city of São Paulo. METHODS Sixty-one individuals with normal fasti...

Recent observational studies have reported controversial results for the association between different anthropometric indices of obesity and severity of atherosclerosis. The aim of the current study is to determine the associations between anthropometric indices with severity of atherosclerosis in adult population in north of Iran.The cross-sectional study was performed on 610 participants, who...

We aimed to estimate the heritability and genetic correlation between glucose homeostasis and adiposity traits in a population in a rural community in Brazil. The Jequitinhonha Community Family Study cohort consists of subjects aged ≥18 years residing in rural areas in Brazil. The data on the following traits were assembled for 280 individuals (51.7% women): body mass index (BMI), body fat perc...

BACKGROUND Body weight has been increasing in the general population and is an established risk factor for hypertension, diabetes, and all-cause and cardiovascular mortality. Patients undergoing peritoneal dialysis (PD) gain weight, mainly during the first months of treatment. The aim of this study was to assess the relationship between body composition and metabolic and inflammatory status in ...

INTRODUCTION Studies suggest that anxiety is an independent predictor of adverse cardiovascular events. However, few studies have investigated the association between cardiovascular risk factors (RF) and severity of anxiety disorders (AD) in childhood and adolescents. OBJECTIVES To assess the prevalence of cardiovascular RF in children and adolescents with anxiety disorders and their associat...

BACKGROUND Various anthropometric indicators can be used as predictors of cardiovascular risk in the elderly. OBJECTIVE Evaluate the predictive capacity of anthropometric measurements in identifying cardiovascular risk in elderly patients at the Family Health Strategy of Viçosa-MG. METHODOLOGY This was a cross-sectional epidemiological study with 349 elderly persons. Cardiovascular risk was...
