organic farming as an approach to sustainable agriculture tries to decrease environmental problems and possible health hazards caused by the residues from pesticides. since the agricultural professionals are responsible to inform the farmers and the public by education and extension efforts, it is necessary to understand their attitudes. the main purpose of this research was to investigate fact...

in order to study the effect of organic fertilizers application on increasing nitrogen efficiency and also quantitative and qualitative characteristics of sugar beet, a series of experiments were performed for two years (2008 and 2009) using three amino acid containing organic fertilizers at motahari research station of sugar beet seed institute (sbsi), karaj, iran. four rates of organic fertil...

in the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (zno) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...

Single crystal devices of organic semiconductors have attracted worldwide attention due to (i) the high performance of organic single crystalline devices and (ii) the possibility of single crystals to reveal the intrinsic chargetransport properties of organic semiconductors. Normally, organic crystals exist as nanometeror micrometer-sized ‘‘small’’ crystals because of the weak interaction betwe...

To promote global food and ecosystem security, several innovative farming systems have been identified that better balance multiple sustainability goals. The most rapidly growing and contentious of these systems is organic agriculture. Whether organic agriculture can continue to expand will likely be determined by whether it is economically competitive with conventional agriculture. Here, we ex...

Mammalian cytochrome P450 reductase (CPR) and cytochrome P450 (CP) play important roles in organic nitrate bioactivation; however, the mechanism by which they convert organic nitrate to NO remains unknown. Questions remain regarding the initial precursor of NO that serves to link organic nitrate to the activation of soluble guanylyl cyclase (sGC). To characterize the mechanism of CPR-CP-mediate...

Global consciousness of food safety, health and environmental issues has stimulated interest in alternative agricultural systems like organic farming. Since information on organic farming of tuber crops is meagre, a field experiment was conducted in split plot design over a five-year period at Central Tuber Crops Research Institute, India. The aims were to evaluate the impact of organic, c...

AcrAB-TolC is a major efflux pump in Escherichia coli. It was reported that tolC is overexpressed and involves in improving the organic solvent tolerance level in Escherichia coli marR mutants that are resistant to several antibiotics, such as ciprofloxacin. Low and intermediate levels resistance did not improve organic solvent tolerance. Thus, in this descriptive-experimental study it was deci...
