3D printed nanofiltration (NF) composite membranes with surface patterns minimising the impact of concentration polarisation (CP) are presented here for first time. The consist a NF polydopamine?coated polyvinylidene fluoride (PVDF/PDA) selective layer on asymmetric wavy (patterned) support. result is membrane pure water permeance 14 ± 2 LMH bar ? 1 and molecular weight cut-off ?550 Da, measure...

Currently accepted pedotransfer functions show negligible effect of management-induced changes to soil organic carbon (SOC) on plant available water holding capacity (?AWHC), while some studies the ability substantially increase ?AWHC through management. The Soil Health Institute's North America Project Evaluate Measurements measured content at field using intact cores across 124 long-term rese...

Kuznetsov’s condition says that variables X and Y are independent when any product of bounded functions f X and g Y behaves in a certain way: the interval of expected values f X g Y must be equal to the interval product f X g Y . The main result of this paper shows how to compute lower expectations using Kuznetsov’s condition. We also generalize Kuznetsov’s condition to conditional expectation ...

Let $G$ be a finite non-abelian $p$-group and $L(G)$ denotes the absolute center of $G$. Also, let $Aut^{L}(G)$ and $Aut_c(G)$ denote the group of all absolute central and the class preserving automorphisms of $G$, respectively. In this paper, we give a necessary and sufficient condition for $G$ such that $Aut_c(G)=Aut^{L}(G)$. We also characterize all finite non-abelian $p$-groups of order $p^...

In this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid G(n). Also we show that G(n) contains commuting regular subsemigroup and give a necessary and sufficient condition for the groupoid G(n) to be commuting regular.

Abstract Background People with Parkinson’s (PwP) lead sedentary lifestyles compared to healthy peers. Personal influences including low self-efficacy and poor outcome expectation appear predict exercise adherence more accurately than disease severity. The purpose of this review is identify successful behavioural-change interventions that promote among PwP. Methods Databases EBSCO, Medline, CIN...

abstract. certain facts about frames and generalized frames (g- frames) are extended for the g-frames for hilbert c*-modules. it is shown that g-frames for hilbert c*-modules share several useful properties with those for hilbert spaces. the paper also character- izes the operators which preserve the class of g-frames for hilbert c*-modules. moreover, a necessary and suffcient condition is ob- ...

A proper edge coloring of a simple graph G from some lists assigned to the edges of G is of interest. A. Hilton and P. Johnson (1990) considered a necessary condition for the list coloring of a graph and called it Hall's condition. They introduced the Hall index of a graph G, h'(G), as the smallest positive integer m such that there exists a list coloring whenever the lists are of length at lea...

in this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid g(n) . also we show that g(n) contains commuting regular subsemigroup and give a necessary and sucient condition for the groupoid g(n) to be commuting regular.
