Bioimpedance spectroscopy (BIS) is a technique of interest in the study of human pregnancy because it can assess extracellular (ECW), intracellular (ICW), and total body water (TBW) as ECW plus ICW. The technique requires appropriate resistivity coefficients and has not been sufficiently evaluated during the reproductive cycle. Therefore, in a methodological study, we estimated ECW, ICW, and TB...

background: in addition to individual problems and conditions, low back pain reduces working capacity, resulting in the waste of time and absence from the work, and increases healthcare costs and economic losses. this study aimed to determine the prevalence rate of low back pain and its relationship to demographic factors, body mass index, and education in ergonomic principles in rural men.   m...

Robust electrical contact of bulk conductors to two-dimensional (2D) material, such as graphene, is critical to the use of these 2D materials in practical electronic devices. Typical metallic contacts to graphene, whether edge or areal, yield a resistivity of no better than 100 Ω μm but are typically >10 kΩ μm. In this Letter, we employ single-crystal graphite for the bulk contact to graphene i...

The ferromagnetic quantum phase transition in the perovskite ruthenate Sr1−xCaxRuO3 is studied by lowtemperature magnetization and electrical resistivity measurements on thin films. The films were grown epitaxially on SrTiO3 substrates using metalorganic aerosol deposition and characterized by X-ray diffraction and room temperature scanning tunneling microscopy. High residual resistivity ratios...
