background and objectives: although more than 90 percent of consumed water used in agricultural sector, water is the major limiting factor for agricultural development in iran. over the past few years increasing agricultural crop water productivity thorough deficit irrigation methods has been studied by agricultural researchers and planners. although lorestan province is one of the major produc...
Lactic acid has been shown to have the most promising application in biomaterials as poly(lactic acid). L. rhamnosus ATCC 10863 that produces L-lactic acid was used to perform the fermentation and molasses was used as substrate. A solution containing 27.6 g/L of sucrose (main composition of molasses) and 3.0 g/L of yeast extract was prepared, considering the final volume of 3,571 mL (14.0% (v/v...
Polypyrrole magnetic graphene oxide (PPy/MGO) composites have been synthesized from a natural source (water hyacinth roots) using polymerization technique for Th(IV) ions pre-concentration from aqueous solutions. The effects of controlling factor have been studied using the batch technique. The obtained results show that the maximum Th(IV) adsorption capacity by PPy/MGO composite is 277.8 m...
the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
Under the crisis of global warming and drastic climate changing, carbon-neutral renewable energy is considerably proposed as a feasible clean alternative energy to fractionally replace fossilized fuel. To cop up with ever stringent emission regulations, researchers have investigated different types of renewable fuels like biodiesel and water emulsion. The fuel physical characteristics are among...
BACKGROUND Safe drinking water is critical for health. Household water treatment (HWT) has been recommended for improving access to potable water where existing sources are unsafe. Reports of low adherence to HWT may limit the usefulness of this approach, however. METHODS AND FINDINGS We constructed a quantitative microbial risk model to predict gains in health attributable to water quality i...
One of the main characteristics of heavy water research reactors is their high production of plutonium. This work demonstrates the possibility of reduction of plutonium production and other actinides in heavy water research reactors. Among the many ways for reducing plutonium production in a heavy water reactor, in this research, changing the fuel from natural uranium to thorium-uranium mixed f...
One of the solutions to reduce pollutants and increase engine power is to use water spray in internal combustion engines. In this type of engine, fuel and water sprays play an important role in engine performance. In this regard, the purpose of this study is to accurately simulate fuel and water sprays and provide optimal coefficients to achieve the best simulation results. For this purpose, th...
due to the deployment of military units in different provinces and different lands and areas in iran and doing many different missions, the amount of fuel consumption of vehicles is not only identical but also different. since the precise measurement of fuel consumption and estimating its needs are important, the factors affecting fuel consumption, military units, including temperature, humidit...
Because of economics, petroleum coke sometimes replaces or supplements coal as a fuel in power plant combustors. Fly ashes were recovered from the combustion of petroleum coke with moderateto high-sulfur Illinois Basin bituminous coal in a western Kentucky power plant. The fly ashes primarily consist of glass, quartz, mullite and spinels. When compared with ordinary fly ashes from Illinois Basi...
