For a provably recursive function f : N→ N of PA one can consider the notion of f -consistency for PA, Conf (PA) := ∀xCon(PA f(x)), where PA k denotes the fragment of PA with induction restricted to Σk formulae. It was shown in [8] that for a certain slow growing function f the strength of PA + Conf (PA) lies strictly between PA and PA + Con(PA). Letting τBH be the Bachmann-Howard ordinal, this...

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...

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...

Propionic acid (PA) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. The present study was undertaken to investigate the effect of PA on liver injury in male rats. Male western albino rats were divided into two groups. The first group served as normal control, the second was treated with PA. The activities of serum hepatospecific ...
