field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...

Cultured cells cloned from the C1300 neuroblastoma have been shown by several laboratories to extend neurites (1-6) and to accumulate nervespecific enzymatic activities (7) when grown under conditions in which cell division is inhibited. Study of this system has been stimulated by the hope that it might serve as an in vitro model of nerve cell differentiation. Many of the neurite-inducing agent...

This paper deals with the au tomat ic t ranslat iou of preposi t ions, which are highly polysemous. Moreover , the same real s i tuat ion is o f t e n e x p r e s s e d b y d i f f e r e n t p r e p o s i t i o n s in d i f f e r e n t languages. We proceed f rom the hypothesis that d i f fe ren t usage pat terns are due to d i f f e ren t conceptual izat ions of the same real s i t u a t i o n...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...
