potential of three physically different formulations of biocontrol agent thrichoderma harzianum199 was investigated in a field trial against wheat common bunt caused by tilletia laevis kühn. wheat seeds of cv. chamran were treated with liquid, semi-solid (gel mixed suspension) and solid (talc powder) formulations prior to planting. field practices were performed based on khuzestan wheat plantin...

Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

Precipitation/dissolution reactions coupled with solute transport are modelled as a cellular automaton in which solute molecules perform a random walk on a regular lattice and react according to a local probabilistic rule. Stationary solid particles dissolve with a certain probability and, provided solid is already present or the solution is saturated, solute particles have a probability to pre...

Porous materials are ubiquitous in the universe and weathering of porous surfaces plays an important role in the evolution of planetary and interstellar materials. Sputtering of porous solids in particular can influence atmosphere formation, surface reflectivity and the production of the ambient gas around materials in space. Several previous studies and models have shown a large reduction in t...

The potential for microbially catalyzed NO3(-)-dependent oxidation of solid-phase Fe(II) compounds was examined using a previously described autotrophic, denitrifying, Fe(II)-oxidizing enrichment culture. The following solid-phase Fe(II)-bearing minerals were considered: microbially reduced synthetic goethite, two different end products of microbially hydrous ferric oxide (HFO) reduction (bioge...

In this study, Al2014 alloy refined with Al-5%Ti-1%B master alloy was prepared by strain-induced melt activated (SIMA) process. The main variables of the SIMA process were cold working, holding time and temperature in semi-solid state. Cold working was applied on specimens by upsetting technique to achieve 10%, 20% and 30% height reduction. Cold worked specimens were heat treated in semi-s...

nowadays the researches have indicated the fact that using synthetic antioxidants as food additives in edible oils can have adverse effects on human health. so preparing antioxidation resources for reduction of oxidation stress effects is important. the aim of this project was, representing a natural antioxidant source with frap test. the present study optimized the ultrasound assisted extracti...

A combined experimental and computational study suggests that a reduction in the entropy of activation in the solid state can lead to the protodeboronation of boronic acids.
