Disordered hyperuniformity (DHU) is a recently discovered novel state of many-body systems that characterized by vanishing normalized infinite-wavelength density fluctuations similar to perfect crystal, yet possesses an amorphous structure like liquid or glass. Due their unique structural characteristics, DHU materials are typically endowed with unusual physical properties, such as large isotro...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...
Coastal and shelf seas provide a diverse range of ecosystem services, which are often mediated by seasonal density stratification through its control on biogeochemical cycles. These highly vulnerable to climate change downscaling studies consistently project an increase in over the next century, but without clear explanation. Here we revisit well-established theory coastal ocean mixing demonstr...
