The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...

regarding the increasing demand for lightweight concrete especially lightweight structural concrete, and safety requirements underlined in 2800 iranian standard, research to achieve the optimized results in lightweight concrete production seems inevitable. since, one of the commonly used methods for producing the light eight concrete, utilizes the light weight aggregates with significant role i...

The reaction of protein-bound iron-sulfur (Fe-S) clusters with nitric oxide (NO) plays key roles in NO-mediated toxicity and signaling. Elucidation of the mechanism of the reaction of NO with DNA regulatory proteins that contain Fe-S clusters has been hampered by a lack of information about the nature of the iron-nitrosyl products formed. Herein, we report nuclear resonance vibrational spectros...

The theme of this initiative is "Waste to Wealth." Construction materials, particularly concrete, need have better qualities, including strength, rigidity, durability, and ductility, because Oman's construction industry expanding. Self-compacting concrete (SCC) has more benefits than regular workability. major focus study the C30-grade SCC for control mix, spent catalyst (zeolite catalyst)-base...

background: biological shielding of nuclear reactors has always been a great concern and decreasing the complexity and expense of these installations is of great interest. in this study, we used datolite and galena (daga) minerals for production of a high performance heavy concrete. materials and methods: datolite and galena minerals which can be found in many parts of iran were used in the con...

BACKGROUND Acidithiobacillus caldus (A. caldus) is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth. Genomic analyses suggest that its sulfur oxidation system involves a truncated sulfur oxidation (Sox) system (omitting SoxCD), non-Sox sulfur oxidation system simila...

Due to the excellent impact resistant performance of steel-plate concrete (SC) structure compared with conventional reinforced (RC) structure, SC is preferred be used in design external walls nuclear island buildings for new power plants (NPPs). This study aims at evaluating effect material and geometric parameters containment on its performance, thus numerical simulation sensitivity analysis s...

Natural fibers investigated in this study are mainly waste from agro industry. The importance of natural building composites is increasing, as they partially replace nonrenewable resources acting reinforcement composite materials such concrete, mortar and earth bricks. Their recycling requires a detailed analysis the physical, chemical, mechanical characteristics fibers. In study, tropical i.e....

A rapid, unified, highly sensitive and selective procedure for bis(2-chloroethyl)sulfide (sulfur mustard, SM) determination in matrices with high sorption activity using gas chromatography-tandem mass-spectrometry (GC-MS/MS) was developed. Ceramic tile, concrete, various types of bricks polymers were studied as objects the analysis. The parameters GC-MS/MS SM optimized. efficiency five solvents...

The low sulfur amino acid content of legume seeds restricts their nutritive value for animals. We have investigated the limitations to the accumulation of sulfur amino acids in the storage proteins of narrow leaf lupin (Lupinus angustifolius) seeds. Variation in sulfur supply to lupin plants affected the sulfur amino acid accumulation in the mature seed. However, when sulfur was in abundant sup...
