The objective of this study is to identify the most suitable portions of the C1 coking coal seam in the North Block of the East-Parvadeh coal deposit (Central Iran), according to ash and sulfur values, using C-N fractal modeling. Based on the C-N log-log plots, different geochemical populations were evaluated based on their sulfur and ash content. They were then divided into five populations ea...

line g11867 was first introduced in iran together with 206 other white, chitti and red beans lines through ciat, and was tested in different breeding experiments from 1992 to 1999. it was selected as a superior line in all experiments. in 2001 this line was evaluated with other six lines for drought tolerance, and it was found to be more tolerant than cv. daneshkadeh the check cultivar. line g1...

In this study the role of glutathione (GSH) in sulfur mustard -induced oxidative stress and cytotoxicity, in human skin fibroblast cell line (HF2FF) was evaluated. Sulfur mustard-induced superoxide radical and hydrogen peroxide formation were evaluated by determination of superoxide dismutase and catalase activity in cell lysate. The cytotoxicity of sulfur mustard was estimated by lactate dehyd...

1. Osmotic shock disrupts particles of phage T2 into material containing nearly all the phage sulfur in a form precipitable by antiphage serum, and capable of specific adsorption to bacteria. It releases into solution nearly all the phage DNA in a form not precipitable by antiserum and not adsorbable to bacteria. The sulfur-containing protein of the phage particle evidently makes up a membrane ...

It is difficult to know whether different dimensions of trust have different effects on local residents' acceptance of nuclear power plants (NPPs). In previous research such trust has been considered as a single dimensional concept. This paper divides trust into goodwill trust and competence trust, and we explore the ways in which trust affects acceptance of NPPs through structural equation mod...

The first structurally characterised two-coordinate hydrido-germylenes, :Ge(H)L (L = -N(Ar){Si(OBu)}, Ar = C6H2{C(H)Ph2}2R-2,6,4; R = Pr(i) ((tBuO)L(†)), Me ((tBuO)L*)), have been prepared, and their dimerisation shown to be thermodynamically unfavourable, largely due to the extreme steric bulk of their amide ligands.

sulfur emission from coal combustion presents many environmental problems. the techniques used to reduce the amount of sulfur in coal before combustion, include physical, chemical and biological processes.biological processes based on degradation of sulfur compounds by microorganisms offer many advantages over the conventional physical and chemical processes. the processes are performed under m...

in the presented work, sulfur concrete and rubber were used for producing functionally graded materials (fgm). the physical and mechanical properties of sulfur concrete and rubber were changed continuously across the thickness. on one side, there was just rubber and, on the other, there was pure sulfur; the properties of each substance were moved to reach another. this kind of material was cons...
