Scarcity of conventional water resources and high volume of wastewaters have increased the important role of crop residues to reduce evaporation from soil surface and optimal use of water, especially in greenhouse cultivation. In the present research, the impact of crop residues and fishery’s wastewater on yield, qualitative characteristics and water productivity of cherry tomato was stud...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
background and objectives: safflower (carthamus tinctorious l.) florets contain valuable red and yellow pigments and are used in food, textile dying, and pharmaceutical industries. red carthamine pigment is formed from a yellow precursor, precarthamine, through an oxidation reaction at the end of flowers' maturation stage. the present study was conducted to find out the most effective procedure...
conclusions the vermicompost as a potential source of plant nutrients for sustainable tomato production can reduce health and environmental problems. results the analysis of the variance results revealed that the effect of the type and amount of fertilizers on tomato yield was significant at 1% level. the results of this study showed that using the vermicompost dosage to cow manure of 500 g/m2 ...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...

Drought stress is one of the most important abiotic stresses in crops that can reduce yield and yield components in terms of time, duration and severity of the stress. Current research was carried out in order to evaluate drought stress tolerance in rice genotypes. Experiment done in two separate schemes using randomized complete blocks design with three replications in Research Field, Faculty ...
CL-20 is the most energetic conventional explosive available for military use. The over all aim of the high energy material research community is to increase the yield and reduce the cost of CL-20 synthesis. All synthetic methods used to prepare the CL-20, depended on the condensation reaction of benzylamine with glyoxal for the preparation of HBIW intermediate . In the presence of HCOOH cata...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
