We have performed density functional theory (DFT) calculations to investigate the properties of defect in arepresentative armchair model of silicon nanotubes (SiNTs). To this aim, the structures of pristine and defective(5,5) SiNTs have been optimized and the properties such as bond lengths, total energies, binding energies,.formation energies, gap energies, and dipole moments have been evaluat...

In the present context, ‘model’ is expressed as a computer program that can be repeatedly run several times for computing designed mathematical or statistical expressions (equations) governing crop growth-environment relations, given appropriate input data. The experiment station yields obtained under rainfed situation without any nutrient deficiency mostly considered potential of crops. Actual...

Precision agriculture (PA) and yield gap (Yg) analysis are promising strategies to achieve the desired sustainable intensification of agricultural production systems. Current crop Yg approaches do not consider internal field variability caused by soil properties. Topographic edaphic characteristics causing consistent high low patterns in time space can be interpreted as an ecological niche used...
