We call a module M , quasi-catenary if for each pair of quasi-prime submodules K and L of M with K L all saturated chains of quasi-prime submodules of M from K to L have a common finite length. We show that any homomorphic image of a quasi-catenary module is quasi-catenary. We prove that if M   is a module with following properties: (i) Every quasi-prime submodule of M has finite quasi-height;...

We used intracellular microelectrodes to study the effect of changes in extracellular calcium ion concentration [Ca]o on the transmembrane potentials of canine cardiac Purkinje fibers in control Tyrode's solution and in the presence of agents thought to modify membrane permeability to potassium. In Tyrode's solution, decreasing [Ca]o from 2.7 to 0.9 mM increased action potential duration measur...

Abstract 30 year old male, who had been hit at 90mph whilst on a motorbike sustaining femoral, tibial and right foot open fractures. He underwent an reduction internal fixation (ORIF) of his lateral femoral condyle, retrograde nail, ORIF the tibia. 2 separate free flaps (a chimera scapular/parascapular antero-lateral thigh-ALT) to lower leg, split skin grafting remainder limb. Upon regular post...

let $g$ be a finite $p$-soluble group‎, ‎and $p$ a sylow $p$-sub-group of $g$‎. ‎it is proved‎ ‎that if all elements of $p$ of order $p$ (or of order ${}leq 4$ for $p=2$) are‎ ‎contained in the $k$-th term of the upper central series of $p$‎, ‎then the $p$-length of‎ ‎$g$ is at most $2m+1$‎, ‎where $m$ is the greatest integer such that‎ $p^m-p^{m-1}leq k$‎, ‎and the exponent of the image of $p$...

Abstract On base of the content Pb in soil under different land use patterns Lanping Lead-zinc mining area, Yunnan southwest China, root morphology and leaf traits maize concentration (20, 40, 60, 80, 100, 150, 200, 500, 1000, 2000, 3000 mg/L) were analyzed. The results showed that germination rate, vigor growth index decreased with increase concentration. length, surface area increased by 0.21...

the length-weight relationship (lwr) and condition factors (cf) of 180 the oriental river prawn macrobrachium nipponense collected from southern coasts of the caspian sea from may through september 2012 were studied. shrimp samples were taken and immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, weight and other external features of ...

This paper presents an experimental study on evaluating the performance of composite geogrid (CGG) reinforced and unreinforced unpaved pavement models using a steel box that has length width height 1.0 m 1.2 respectively. A subgrade CBR 2.5% (unsoaked) was prepared to thickness 500 mm, then granular base compacted top subgrade. Three course thicknesses, namely 200 300 mm 400 were adopted in thi...

Though land use regression (LUR) models have been widely utilized to simulate air pollution distribution, unclear spatial scale effects of contributing characteristic variables usually make results study-specific. In this study, LUR models for PM2.5 in Houston Metropolitan Area, US were developed under scales of 100 m, 300 m, 500 m, 800 m, and 1000–5000 m with intervals of 500 m by employing th...
