‎Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$‎. ‎Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$‎. ‎We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$‎, ‎$bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$‎. ‎I...

conclusions it seems that plantar changes have insignificant effect on static and dynamic indices evaluated by the biodex balance system. objectives the current study aimed to evaluate the relation between these structural characteristics and balance indices. patients and methods the study population was 100 male and female students from semnan university of medical sciences, semnan, iran. to e...

In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...

Abstract Many existing historical masonry arch bridges used in the road and railway networks are still service. However, most of them show a structural performance deficit due to several factors. This study deals with seismic behavior assessment an three‐arched bridge through nonlinear, non‐adaptive static analysis carried out by three‐dimensional Finite Element model. Input data were collected...

The track–bridge interaction is a fundamental concern in the field of railway engineering, which plays an important role optimization design bridges, especially for heavy-haul and high-speed bridges. This paper systematically introduces research status CWR large-span bridges China. evolution process model from simplest elastic bar linear longitudinal resistance to complex beam–rail considering ...

The most common surgery for the correction of congenital funnel chest in 21st century is Nuss procedure. This intervention accompanied by complications related to actual fixing bar and its size placement methods fixing. these are displacement chronic postoperative pain. Only one corrective (thickness, width) used this type operation all age groups. Purpose – develop implement original modificat...

During the passage of a tube from nostril to trachea certain difficulties may be encountered. The anterior nasal opening may be unusually narrow, there may be a septal deflection or spur, or an inferior turbinate;; may be tiresomely over-sized. On such occasions, of course, the effect of rotation of the tube is tested, the other nostril is tried, or a narrower^ tube used. However, a little beyo...
