introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...
background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...
Sulfate-bearing soils, which causes many engineering problems, e.g., cracking, collapse, and pavement layer settlement, are often encountered in the construction of pavements. Ground granulated blast furnace slag (GGBS)-magnesia (MgO) has been regarded as an effective curing agent treatment sulfate-bearing soil containing gypsum. However, field soils usually include other forms sulfates, such s...
Hydrogen sulfide is frequently met in natural waters, like mineral springs, but mostly it found marine water with low renewal rate. The Black Sea has extremely high hydrogen content. It can be utilized different ways, the most promising one direct conversion into electricity. This result attained by a sulfide-driven fuel cell (SDFC), converting to sulfate thus releasing electric energy up 24 GJ...
INTRODUCTION Renal colic can be managed by preventing the contraction movements of ureter muscles. By reducing acetylcholine in the nerve terminals, magnesium sulfate could be effective in this regard. The aim of this study is to investigate the effect of magnesium sulfate on acute renal colic pain relief. METHOD The present study was a double-blind clinical trial in which the patients suffer...
objective: finding a suitable laboratory test that can diagnose schizophrenia in its early stages could be very important. according to the hypothesis of lack of noradrenalin balance in the brain, it is illustrated that the disorder severity has a negative correlation with the amount of urine noradrenalin metabolite [3-methoxy-4-hydroxy phenyl glycol (mhpg) sulfate]. in this research, instead o...
the oxidation of ferrous iron (fe2+) in solution using acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. the aim of this investigation was to increase the...
In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...
Background: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantification of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require sp...
In a randomized double blind clinical trial study with two parallel group, we assessed the analgesic effect of perioperative magnesium sulfate administration and its effect on serum norepinephrine 24h after diagnostic artheroscopic surgery in 50 ASA physical status I & II patients under general anesthesia with total intravenous anesthesia (TIVA) technique. The patients received either m...
