OBJECTIVES (1) To examine the validity of existing prediction equations (PREE) for estimating resting energy expenditure (REE) in obese Chinese children, (2) to correlate the measured REE (MREE) with anthropometric and biochemical parameters and (3) to derive a new PREE for local use. DESIGN Cross-sectional study. SUBJECTS 100 obese children (71 boys) were studied. MEASUREMENTS All subjec...

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...

O estudo clínico das diferentes patologias e doenças humanas é complexo, porque a influência de vários fatores, por vezes com relações interdependentes, se conjugam entre si. Assim, e para se poderem estabelecer relações causais, são necessários estudos bem delineados e poderosas ferramentas analíticas. Os ensaios clínicos aleatorizados, controlados, têm sido considerados como evidência de níve...

OBJECTIVE To investigate the agreement in evaluation of risk of developing cardiovascular diseases based on anthropometric parameters in young adults. METHODS The study included 406 students, measuring weight, height, and waist and neck circumferences. Waist-to-height ratio and the conicity index. The kappa coefficient was used to assess agreement in risk classification for cardiovascular dis...

The aim of the present investigation was to calculate stress distribution generated in root dentine canal during mechanical rotation five different NiTi endodontic instruments by means a finite element analysis (FEA). Two conventional alloy F360 25/04 and F6 Skytaper 25/06, comparison three heat treated alloys NiTI Hyflex CM 25/04, Protaper Next 25/06 One Curve were considered analyzed. instrum...

This paper points out how the nonlinearities involved in multivariable Takagi–Sugeno (T–S) fuzzy control systems could originate complex behavior phenomena, such as multiple equilibrium points or limit cycles, that cannot be detected using conventional stability analysis techniques. In the paper, the application of MIMO frequency-domain methods to predict the existence of multiple equilibria an...

BACKGROUND Established indicators of central obesity include waist circumference, waist/height ratio, and the conicity index. Studies using such measures (as opposed to body mass index [BMI] percentiles) to characterize the association between obesity and asthma are lacking, despite the fact that these measures have been shown to be most relevant for many other chronic diseases. OBJECTIVES We...

BACKGROUND Limited data are available on left ventricle (LV) diastolic function in patients with ischemic dilated cardiomyopathy submitted to surgical ventricular restoration (SVR). The purpose of this study was to assess postoperative diastolic function changes and identify potential predictors of its worsening. METHODS One hundred and forty-six patients (65 +/- 9 years) with previous anteri...
