Efficiency of nitrogen fertilization in spring wheat
An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

Memory Protection Scheme: Nooks Architecture vs. Mondrian Protection Scheme
1.0 Abstract In recent times, there is a big explosion of embedded devices like PDAs and digital cameras in the consumer market arena. In order to incorporate these new devices into the computer systems a large number of device drivers have been written by different vendors. One way to define device drivers is to view them as an extension to the operating system kernel. Today the preferred way ...
متن کاملSodium Chloride Salt Tolerance Evaluation and Classification of Spring Rapeseed (Brassica napus L.)
Abiotic stresses such as salinity, are factors that severely affects agricultural production. To evaluate the effects of salinity on some morphological and physiological traits related to salt tolerance of 22 genotypes of spring rapeseed cultivars in the vegetative growth stage, an experiment was conducted as a split plot form based on Randomized Complete Blocks Design using levels of salinity:...
