The synergistic effect of WC and Pd has large benefit for ethanol electrooxidation. The small-sized Pd nanoparticles (NPs) decorated tungsten carbide on graphene (Pd-WC/GN) will be a promising anode catalyst for the direct ethanol fuel cells. The density functional theory (DFT) calculations reveal that the strong interaction exists at the interface between Pd and WC, which induces the electron ...

BACKGROUND/AIMS Anthropometric measures such as body mass index (BMI) and waist circumference (WC) have differential associations with incident chronic kidney disease (CKD) and mortality. We examined the associations of BMI and WC with various CKD complications. METHODS We conducted a cross-sectional analysis of 2,853 adult participants with CKD in the National Health and Nutrition Examinatio...

AIM/INTRODUCTION We evaluated the association between hypertriglyceridemic waist (HTW) phenotype and the risks of type 2 diabetes in an Iranian high-risk population. MATERIALS AND METHODS We analyzed 7-year follow-up data (n = 1,865) in non-diabetic first-degree relatives of consecutive patients with type 2 diabetes aged 30-70 years. The primary outcome was the diagnosis of type 2 diabetes ba...

In this work infiltration behavior of mechanical alloyed 75 wt% Cu – 25 wt% WC powders into porous WC compacts were studied. Owing to their ductile nature, initial Cu powders were directly added to mechanical alloying batch. On the other hand initial WC powders were high energy milled prior to mechanical alloying. Contact infiltration method was selected for densification and compacts prepared ...

Monitoring the push force is an important asset during wheelchair (WC) sports training. However, current instrumented wheels cannot be used without significantly altering the WC-user dynamics. Moreover, the push force could not be estimated directly from the WC acceleration because of the strong influence of the upper body movement on the WC-user dynamics. In this paper, we present a new method...

There are conflicting data as to whether general or abdominal obesity is a better predictor of cardiovascular risk. This cross-sectional study involved 4,573 subjects aged 30 to 74 yr who participated in the Fourth Korea National Health and Nutrition Examination Survey conducted in 2008. Obesity phenotype was classified by means of body mass index (BMI) and waist circumference (WC), and partici...

There is currently no consensus regarding the optimal protocol for measurement of waist circumference (WC), and no scientific rationale is provided for any of the WC protocols recommended by leading health authorities. A panel of experts conducted a systematic review of 120 studies (236 samples) to determine whether measurement protocol influenced the relationship of WC with morbidity of cardio...

Introduction: Waist circumference (WC) and waist-to-height ratio (WHTR) are used to screen the central obesity and identify metabolic syndrome. These parameters are dependent on sex, age and ethnicity, thus requiring specific values in each country. The study aims to develop age and gender specific WC and WHTR percentile curves for Thai youth. Method: This is a cross-sectional study based on th...

our aim was to evaluate the association of metabolic syndrome (mets) and its components with body fat percentage (bfp) and anthropometric indicesin10 to 18year old adolescents.this was a cross-sectional study conducted on 134 tehranian adolescents, aged 10 to 18 years (66 boys and 68 girls) in 2007. the mets definition proposed by cook et al. was used. logistic regression was used to determine ...
