an infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. the two-dimensional coupled thermoelastodynamic pdes are specified based on equations of motion and energy equation, which are uncoupled using nowacki potential functions. the laplace integral transform and bessel-fourier series are u...

in this paper, we study the notion of solvable $l$-subgroup of an $l$-group and provide its level subset characterization and this justifies the suitability of this extension. throughout this work, we have used normality of an $l$-subgroup of an $l$-group in the sense of wu rather than liu.

let r be a ring, m a right r-module and (s,≤) a strictly ordered monoid. in this paper we will show that if (s,≤) is a strictly ordered monoid satisfying the condition that 0 ≤ s for all s ∈ s, then the module [[ms,≤]] of generalized power series is a uniserial right [[rs,≤]] ]]-module if and only if m is a simple right r-module and s is a chain monoid.

Baer has shown that, for a group G, finiteness of G=Zi(G) implies finiteness of ɣi+1(G). In this paper we will show that the converse is true provided that G=Zi(G) is finitely generated. In particular, when G is a finite nilpotent group we show that |G=Zi(G)| divides |ɣi+1(G)|d′ i(G), where d′i(G) =(d( G /Zi(G)))i.

which now are threatened by A. glabripennis and EAB, respectively. Identification of the EAB infestation in Michigan began when iridescent green beetles collected from dying ash near Detroit were submitted to Michigan State University Department of Entomology in June 2002. On July 9, 2002, the beetles were conclusively identified as A. planipennis by Dr. Eduard Jendek of Slovakia, the world aut...

(Developmental Cell 16, 83–92; January 20, 2009) In following up the experiments reported in this paper, we have discovered that the polarity phenotypes ofDystroglycan and perlecan mutant clones under starvation conditions shown in Figures 4, 5, 6F, 6H, and 6J are the result of an artifact. We now believe that these panels do not represent real clones with a polarity phenotype, but rather false...

The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Col., Buprestidae), an invasive pest currently threatening the complete destruction of North America’s ash resource, was first detected in the Midwestern United States and adjacent Canada in 2002 (Haack et al. 2002). Effective detection and monitoring of this pest has so far remained elusive (Poland and McCullough 2006). Identifying a ...

background: this study attempted to investigate traffic accident fatalities during 2004-2009 and the effect of fuel rationing on traffic accident fatalities .   materials and methods: this was a cross-sectional study on available data of all traffic accident fatalities in fars province, iran, during 2004-2009. to identify and fit the best model, various instruments, including the autocorrelatio...
