Abstract:
Based on surface protection problems of the steel part of the landing gear, wear-resisting properties of tungsten carbide-cobalt (WC-Co) particles reinforced epoxy (WRE) coatings were investigated in this paper. The curing process of WRE coating was analyzed by DSC, TG and IR. The wear performance under different rotational speed WRE coating was studied respectively. The specific wear rates of the WRE coating at 560 rpm and 840 rpm are 6.04 ×10−4mm3N−1m−1and 9.55 ×10−4mm3N−1m−1respectively, about only 60% of that of the uncoated sample. Thus, this could be summarized that WRE coating had a goo

Abstract:
Abstract Objectives Sodium intake has been widely studied for its role in cardiovascular disease (CVD) and blood pressure (BP) changes. Some studies have suggested that sodium intake is associated with an increased risk of obesity. Although BMI is a common measure of obesity, waist circumference (WC) may serve as a better predictor of increased obesity-related CVD risk. The objective of this study was to examine the association of measures of body fat distribution including body mass index (BMI), WC, waist to hip ratio (WHP), and waist to height ratio (WHT) with sodium intake and BP in older a

Background Body fat distribution influences the risk of cardio-metabolic disease in people with overweight. This study was aimed at identifying the anthropometric parameters more strongly associated with the majority of cardio-metabolic risk factors.

For investigating the correlation with spectral CT imaging parameters and occult lymph nodes metastasis in sufferers with isolated lung adenocarcinoma. The clinic cases data of 352 sufferers with isolated lung adenocarcinoma from January 2019 to January 2022 were assembled. In line with whether the sufferers had occult lymph nodes metastasis, they were taken as a part in the metastasis group (n = 172) and the nonmetastasis group. All sufferers were scanned by spectral CT with a dual-phase contrast-enhanced method, and the recording of spectral CT imaging parameters in arteriovenous phase, iodi

AbstractComprehensive screening for non-alcoholic fatty liver disease (NAFLD) may help prompt clinical management of fatty liver disease. A family history, especially of diabetes, has been little studied as a predictor for NAFLD. We characterized the cross-sectional relationship between a family history of type 2 diabetes (FHT2D) and NAFLD probability in 1185 diabetes-free Apulian (Southern-Italy) subjects aged > 20 years with overweight or obesity not receiving any drug or supplementation. Clinical data and routine biochemistry were analysed. NAFLD probability was defined using the fatty l
