summary based on the results of the analysis of site effects, mostly those with shear wave velocity and the fundamental period chosen as the basis for classification. in revision of earthquake resistant design regulations for buildings, classification of lands should be subject to the field conditions, geological, geotechnical, geophysical, and laboratory tests.in this context, the average shea...

abstract this study was conducted to evaluate the resistance of 70 genotypes of barley to powdery mildew. after preparing the samples contaminated with powdery mildew, reproduction of the spores of the fungus was conducted on susceptible cultivar afzal. the experiment was conducted with randomized block design in pot in greenhouse. seedlings were inoculated with the spores fungus in two-leaf st...

to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...

introduction groundwater resources in arid-semiarid zones universally suffer from problems of over-abstraction and declining water tables. in addition to the issues related to quantity, degradation of groundwater quality now assumes major importance in the arid and semiarid regions. in such areas, natural factors such as the low precipitation, combined with high evapotranspiration, result in hi...

in this study, the effect of drought and different concentrations of silicon was examined on seed yield, essential oil percentage and physio-chemicals properties in fennel plant. the experimental design was a split plot with three irrigation regimes: irrigation at 100, 70 and 40 percent of fc comprising the main treatments, and five levels of silicon foliar sprays (0, 2.5, 5, 7.5 and 10 mm) as ...

plant analysis is successfully used in monitoring nutritional status, recommending fertilizer rates and types, and maximizing fertilizer efficiency in sugar beet. diagnosis and recommendation integrated system (dris) is a comprehensive approach which does not have limitations of the critical value approach (cva) and sufficiency range approach (sra). over- dose application of fertilizer increase...

to evaluate the anti-transpiration effect on yield and yield components of corn late yield 704 under drought stress experiment split factorial randomized complete block design with three replications in spring 2012 at the research station, kermanshah. and paclobutrazol treatments include salicylic acid, which is taking on two levels. based on the values determined in the following order foliar ...

sawdust of the most inexpensive and abundant most engrossing read and the ability to absorb heavy metals from water and wastewater types. on the other hand increased metal hexavalent chromium (cr6 +) in drinking water cause toxicity, and complications from it can be. so the purpose of this research, effects of the dosage absorbent sawduste, equilibrium time, the efficiency of absorption and cal...
