Background: Old age is accompanied by impaired musculoskeletal and nervous system, which may result in low mobility and cognitive problems. This study aims to evaluate the relationship between Physical Activity (PA) and Cognitive Function (CF) among the elderly population. Objectives: ?? Materials & Methods: This is a descriptive cross-sectional study conducted on 200 old people who were memb...

Here, we demonstrate a new approach for the synthesis of ion exchange microfibers with finely tuned anhydrous conductivity. This work presents microfluidics as a system to control the size and phosphoric acid (PA) doping level of the polybenzimidazole (PBI) microfibers. It has been shown that the PA doping level can be controlled by varying the flow ratios in the microfluidic channel. The diame...

Stewart's physicochemical approach was used to study the effects of pregnancy on acid-base regulation in arterialized blood. Responses of 15 healthy pregnant women (PG; gestational age, 37.1 +/- 0.2 wk) were compared with those of 15 nonpregnant controls (CG) at rest and during cycling at 70 and 110% of the ventilatory threshold (T(vent)). Hydrogen ion concentration ([H(+)]) was lower in the PG...

As indicated by its title, the book ‘Chemistry for Environmental Scientists’ aims at covering a very broad field of knowledge. After a short and general introduction, it is divided in four chapters, namely ‘Chemistry under environmental conditions’, ‘Fundamentals of physical chemistry’, ‘Chemistry of the elements and its [sic] compounds in the environment’ and ‘Chemical processes in the environ...

The cutting, lay-up and bagging of out-of-autoclave (OOA) prepregs for composite part fabrication can take from several days to weeks, depending on the desired part size. This period of ambient temperature “out-time” induces resin polymerization/cross-linking, and affects critical physicochemical phenomena such as minimum viscosity, gelation, and vitrification. Therefore, the capability to moni...

Background: DNA vaccines are third generation vaccines which have made promises to combat infectious diseases. Cationic liposomes are used as effective delivery systems for DNA vaccines to generate stronger immunity. Objective: Encapsulation of pcDNA3.1+PA plasmid, encoding protective antigen (PA) of Bacillus anthracis (B. anthracis) into cationic liposomes, and evaluation of its effect on spec...

Introduction: There are strong evidences to support the relation between Physical Activity (PA) and improved health in older adults. So this study aimed to determine the predictors of PA among a group of older adults in northwest of Iran.   Methods: In 2016, a randomly sample size of 340 older people in urban regions of Maku, West Azerbaijan, Iran, was recruited to complete Physical Activity ...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
