in order to study the qualitative, quantitative characteristics of a pure common populus alba stand in polkalleh & a mixed stand of populus alba & populus nigra in karchegan, two 30-year-old stands were selected with a plantation interval ( spacing) of 2.5 × 1.5 m in each of which 30 pcs of 2 are samples were randomly selected. in each sample pc all the trees diameters were measured using a dia...

in this paper, we will give necessary and sufficient conditions for certain hnnextensions of subgroup separable groups with normal associated subgroup to be conjugacyseparable. in fact, we will show that these hnn extensions are conjugacy separable if and onlyif the normalizer of one of its associated subgroup is conjugacy separable.

we prove that if $m$ is a monoid and $a$ a finite set with more than one element‎, ‎then the residual finiteness of $m$ is equivalent to that of the monoid consisting of all cellular automata over $m$ with alphabet $a$‎.

pediatric traumatic limb amputations are rare and their acute and long term management can be challenging in this subgroup of patients. the lengthy and costly hospital stays, and resulting physical and psychological implications leads to significant morbidity. we present a summary of treatment principles and the evidence base supporting the management options for this entity. the initial manage...

in this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (cnts) is proposed in detail. the negative coefficient of thermal expansion and the high young’s modulus of cnts can be utilized to counterbalance the process induced residual stresses in composites. to this end, first, the effects of adding cnts to the matrix of fibrous composi...

in this research,for taxonomic studies and identification of the fungi associated with the powdery mildew(oidium euonymi- japonici) of buxus trees (euonymus japonica), the infected leaves were collected during autumn and winter 2012-2013 in gorgan (golestan province -iran). the samples after washing and surface sterilizing, were cultured on pda medium(with boxwood extract).then based on availab...

the residual activity and air-borne efficacy of etofenprox (trebon 20% wp) were studied on different surfaces in hut scale trial, in kazeroun south of iran, in 1992. the bio-assay contact mortality tests with trebon against anopheles stephensi showed similar responses on pluster, cement and mud surfaces (except wooden surfaces), i.e. at 250, 400 and 500 mg/m2, trebon had residual activity for a...

numerous studies have documented a temporary decrease in growth following prescribed burning (e.g., Landsberg et al. 1984, Grier 1989, Sutherland et al. 1991, Peterson et al. 1994, Busse et al. 2000), whereas other studies have reported a positive growth response in ponderosa pine (Wyant et al. 1983, Skov et al. 2005), giant sequoia (Mutch and Swetnam 1995), and Douglas-fir (Reinhardt and Ryan ...
