Ibuprofen (I) is the most widely used non-steroidal anti-inflammatory drugs (NSAIDs) has been synthesized in recent years. NSAIDs are the first choice of drugs that are normally used for the treatment of pain and inflammation. There are many methods for synthesizing of I but each one has some difficulties as raw materials preparation, reaction conditions and etc. In an effort to establish modif...

In this study effect of irrigation managements including irrigation after 100 and 200 mm pan evaporation as normal and deficit irrigation respectively was investigated in Roselle plants. Effects of humic acid (including 0 and 4 kg ha-1) and mycorrhizal inoculants (including Glomus versiforme (GV) and Rhizophagus irregularis (RI)) were also studied on growth, yield and mycorrhizal symbiosis inde...

First-order logic (FOL) is undecidable — that is, no algorithm exists that can decide whether a formula of FOL is valid or not. However, there are various fragments of FOL that are known to be decidable. FO, the two-variable fragment of FOL, is one of such languages [1,2]. FO is a first-order language where formulas have maximally two variables, no function symbols, but possibly do have equalit...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

Optimization of Bacillus subtilis (isolate B246) growth conditions for mass cell production under laboratory conditions was investigated as part of a biological control programme. Aspects such as increasing yield using various starter culture volumes, various media and incubation time and temperatures, were studied. No significant differences between starter culture volumes were found. Potato m...

Bacillus isolates were analyzed for alkaline protease production on casein containing agar plates and identified by clear zones of casein hydrolysis around colonies. Two gram positive Bacillus isolates S5 and C3 which showed the best enzyme production were studied for purification by precipitation and dialysis. The intracellular alkaline protease enzyme was purified about 4 fold with a yield of...

Two types of grape pomace were ensiled with eight strains of lactic acid bacteria (LAB). Both fresh grape pomace (FrGP) and fermented grape pomace (FeGP) were preserved through alcoholic fermentation but not malolactic conversion. Water leaching prior to storage was used to reduce water-soluble carbohydrates and ethanol from FrGP and FeGP, respectively, to increase malolactic conversion. Leache...

Abundant plant biomass has the potential to become a sustainable source of fuels and chemicals. Realizing this potential requires the economical conversion of recalcitrant lignocellulose into useful intermediates, such as sugars. We report a high-yielding chemical process for the hydrolysis of biomass into monosaccharides. Adding water gradually to a chloride ionic liquid-containing catalytic a...

Chitosanase production of Gongronella sp. JG cells immobilized in calcium alginate gel and polyurethane foam was compared with that of the free cells, there was a 60% increase in the enzyme yield (2429 U/L) compared to the highest yield obtained from free cells (1513 U/L). The optimal immobilization parameters (concentrations of sodium alginate, calcium chloride, bead inoculums, bead diameter, ...
