Abstract The use of bioimpedance has made important advances in recent years, achieving estimation of body composition, such as water, fat mass, muscle mass, or ions, among others. These determinations could be used to corroborate clinical diagnoses. In this study, the body composition of university subjects was determined using bioimpedance and compared with biochemical determinations of metabolic analytes (lipoproteins, triglycerides, and lipids) in diabetic and healthy conditions. The results showed an increase in total fat mass in both men and women, as well as a decrease in skeletal muscl

As a perceptual quality of life, living convenience is an essential social indicator in contemporary urbanism. A high degree of living convenience in daily life means people can meet most of their needs within a short travel time, bringing a series of bene fits in terms of liveability. However, it was diffi cult to measure this intangible, subjective issue quantitatively. Therefore, analysis of the relationship between various elements of urban form and living convenience is needed.

Abstract:

The order of the relative degree of iron oxide coating of 4 samples of red soils from north-eastern Argentina was established using the point of zero charge (PZC), yielded by potentiometric titration, and the isoelectric point (IEP), obtained from the diffusion potential. When PZC is different from IEP, the relative fraction of apparent surface coverage could be assessed from the IEP. The results obtained by the application of X-ray diffraction, scanning electron microscopy, electron probe microanalysis, X-ray photoelectron spectroscopy, M&ouml;ssbauer spectroscopy, and specif ic surface a

Meticulous diagnosis and prompt therapy may help to prevent malignant transformation. The assessment of Micronuclei (MN) in exfoliated oral epithelial cells is a promising tool for the study of epithelial carcinogen
