background: testicular torsion is a medical emergency with catastrophic sequelae that deserves the same treatment considerations and concerted efforts in research as any other complicated medical condition. the aim of this study was to investigate the effect of pausinystalia macroceras (pm) bark extract on sperm quality and serum testosterone levels in testicular torsion in a rat model. methods...

A hypothetical pseudoscalar particle axion, which is an immediate result of the Peccei-Quinn solution to strong $CP$ problem, may couple gluons and lead oscillating electric dipole moment (EDM) fundamental particles. This paper proposes a novel method probing axion-induced EDM in storage rings, using radio frequency (rf) Wien filter. The filter at sidebands axion $g\ensuremath{-}2$ frequency, $...

The aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎It is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

background: the present study investigated the effect of the middle east dust storm episodes on the concentration and composition of pm 10 during april to september 2013 in sanandaj city, western iran. methods: sampling was once every six days, and on dusty days using an omni air sampler. the pm 10 sample was collected on polytetrafluoroethylene filters. average of 24 h values of pm 10 mass con...

in order to perform preventive maintenance (pm), two approaches have evolved in the literature. the traditional approach is based on the use of statistical and reliability analysis of equipment failure. under statistical-reliability (s-r)-based pm, the objective of achieving the minimum total cost is pursued by establishing fixed pm intervals, which are statistically optimal, at which to replac...

The high biocompatibility and durability of disposable extracorporeal centrifugal blood pumps (CBPs) utilizing magnetic bearing or bearingless motor technology make them perfect for supporting cardiopulmonary circulation patients. However, the rotor incorporated in unit typically uses high-cost environmentally-unfriendly rare-earth permanent magnets (PMs), leading to economic environmental issu...

in industries, preventive maintenance (pm) is not a new practice to minimise the sudden breakdown of production machine. pm will be performed at predetermine intervals to provide a balance between failure cost and component utilisation (aging). however, most of pm interval is based on experience or original equipment manufacturer (oem) recommendations. consequently, the benefits from pm are not...

Large size single crystals of potassium L-ascorbate monohydrate (KLAM), (KC6H7O6.H2O) are grown using solution growth technique by lowering the temperature at rate 0.24 {\deg}C/h, where water was used as solvent. The structure KLAM solved crystal XRD. crystallizes in non-centrosymmetric, monoclinic, P21 space group with lattice parameters a = 7.030(5) {\AA}, b 8.811(5) c 7.638(5) {\AA} and \b{e...
