توانایی گیاه پالایی خاک¬های آلوده به سرب کلن¬ 154/62 تبریزی (p. nigra) و کلن 9/44 سپیدار(p. alba) همزیست شده با قارچ¬های میکوریز آربوسکولار بررسی شد. آزمایش به صورت فاکتوریل در قالب طرح بلوک¬های کاملا" تصادفی با دو فاکتور 1) قارچ میکوریزی در 5 سطح (شاهد، glomus mosseae،g. intraradices، g. mosseae + g. intraradices و جمعیت قارچی خاک آلوده به سرب) و 2) سرب در 4 سطح (شاهد، 100، 500 و 1000 mg/kg) ط...
Populus alba is fast and auto- growing tree which profoundly accessible in around the world. The usage of the wastes of this tree would be admirable from environmental and solid waste management point of view. Thus, herein, this data set presents a facile method for providing an adsorbent from wastes of P. alba tree. The prepared adsorbent was modified by the cationic surfactant of (C16H33)N(CH...
We examined gene expression patterns in the lignin-degrading fungus Phanerochaete chrysosporium when it colonizes hybrid poplar (Populus alba × tremula) and syringyl (S)-rich transgenic derivatives. A combination of microarrays and liquid chromatography-tandem mass spectrometry (LC-MS/MS) allowed detection of a total of 9,959 transcripts and 793 proteins. Comparisons of P. chrysosporium transcr...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
The increasing prevalence of antibiotic resistance in bacterial pathogens has renewed focus on natural products with antimicrobial properties. Lantibiotics are ribosomally synthesized peptide antibiotics that are posttranslationally modified to introduce (methyl)lanthionine bridges. Actinomycetes are renowned for their ability to produce a large variety of antibiotics, many with clinical applic...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
In the present study the bark of Plumeria alba Linn. (Apocynaceae) was evaluated for pharmacognostical and phytochemical parameters and methanolic extract for antimicrobial activity by determining its MIC (by checker board method) and zone of inhibition (by cup plate method).Pharmacognostical parameters of the bark of Plumeria alba Linn. (Apocynaceae) were studied with the aim of drawing the ph...
Asexual reproduction is a common and fundamental mode of reproduction in plants. Although persistence in adverse conditions underlies most known cases of clonal dominance, proximal genetic drivers remain unclear, in particular for populations dominated by a few large clones. In this study, we studied a clonal population of the riparian tree Populus alba in the Douro river basin (northwestern Ib...
