To assess the effects of different levels of soil lead on mineralization of organic carbon and nitrogen, a factorial pot experiment was conducted using litter bag method. The factors examined were different levels of soil lead (0, 25, 50, 100, and 200 mg kg-1soil) and incubation periods (1, 2, 3 and 4 months) in three replications. At the end of incubation periods, the litter bags were pulled o...

Backgrounds and Objectives: Powdered Activated$ carbon is known as a suitable absorbent for organic materials. The aim of this research is evaluation of Powdered Activated-Carbon (PAC) efficiency in removal of Dissolved Organic Carbon (DOC) in water treatment in Isfahan.Materials and Methods : The increase of PAC for DOC reduction has done in three paths in the Isfahan water treatment plant (WT...

In this work, the first in the world of science, the focus was on the best angle of connection between carbon nanotubes and the most widely used group of antibiotics. While having the highest stability, in terms of energy, we have the best angle of to connect to the in vivo delivery of intraoperative antibiotic binding with carbon nanotubes not lost. It will never work in the world of science. ...

Since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. After gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, One of these methods is activated carbon.The loading of gold from industrial thiosulfate solut...

Climate changes and global warming are considered as very important challenges of sustainable development. Carbon sequestration is the easiest and cheapest way to reduce the greenhouse gases, especially carbon which constitutes the largest portion of them. In the present study, the potential of carbon sequestration in four plant species of Atriplex canescens, Haloxylon persicum, Artemisia siebe...

Some strawberriy cultivars (Fragaria x ananassa Dutch. cv. Aliso, Selva, Gaviota and Camarosa) were grown hydroponically with five NH4:NO3 mM concentration ratios (0/6 (S1), 0.25/6 (S2), 0.5/6 (S3), 1/6 (S4), 2/6 (S5) and constant nitrate concentration in three replicates for two seasons: Summer and Winter, in greenhouses of Agriculture Faculty of Tehran University. The results are reported as ...
