today oil removal from contaminated soil by new methods such as bioremediation is necessary.  in this paper, the effect of chemical fertilizers and aeration on bioremediation of oil-contaminated soil has been investigated. also the control group, (bioremediation of petroleum hydrocarbons in contaminated soil without treatment by chemical fertilizers and aeration treatment was examined. the cond...

in this study, the possibility of estimating wheat density was investigated by using a non-destructive method of output voltage of the light received by the photovoltaic cells. for the static tests, treatments and procedures, a system was designed and built. an experiment with different density on the wheat crop was carried out. the components of optical system clouding: photocells, led lights ...

this study was designed to investigate the structural characteristics of beech forests in the middle stage of ecological succession. in order to this purpose undisturbed beech stands in kheyroud forest had chosen and three one hectare sampling plot laid out. all of tree species measured with full callipering method and diameter and height of trees were recorded. natural regeneration within one ...

Snow depth (SD) knowledge is significant in many applications related to hydrology, climate, and disaster management. Many snow models are developed using multifrequency spaceborne passive microwave (PMW) brightness temperature (Tb) observations because of their sensitivity SD. The Tb SD affected by metamorphism, which constrains the utility several empirical conceptual for estimating For first...

Cretaceous mafic dykes in the Moyar Shear Zone (MSZ) area, north Kerala, India, provide signatures to probe into the nature of their source and thereby the evolution of the Mesozoic lithospheric mantle beneath the South Indian Granulite Terrain (SIGT). Bulk of the dykes in northern parts of Kerala is broadly in spatial association with the shear system. Mafic dykes striking NE-SW, NWSE, NNW-SSE...

Vertical variation in sorption and mineralization potential of mecoprop (MCPP), isoproturon and acetochlor were investigated at low concentrations (μg-range) at the cm-scale in unsaturated sub-surface limestone samples and saturated sandy aquifer samples from an agricultural catchment in Brévilles, France. From two intact core drills, four heterogenic limestone sections were collected from 4.50...

clinically relevant embolic events during peripheral interventions is low, and most of these events can be successfully managed during the index procedure, as shown by the study of Shrikhande and colleagues and Dieter and Najundappa. However, nothing is known about the clinical consequences of initially silent distal embolic events in patients undergoing repetitive redo procedures. In particula...

using low quality water on agricultural lands in south of tehran has increased the risk of soil salinity and created problems for some agricultural crops. this study was carried out to determine of soil salinity distribution and to produce salinity map. the mapping of salinity can also identify the saline and non-saline regions that are very effective for land management and choosing kind of cr...
