The particle-particle random phase approximation (pp-RPA) has been shown to be capable of describing double, Rydberg, and charge transfer excitations, for which the conventional time-dependent density functional theory (TDDFT) might not be suitable. It is thus desirable to reduce the computational cost of pp-RPA so that it can be efficiently applied to larger molecules and even solids. This pap...
Excitonic effects in solids can be calculated using the Bethe-Salpeter equation (BSE) or the Casida equation of time-dependent density-functional theory (TDDFT). In both methods, the Tamm-Dancoff approximation (TDA), which decouples excitations and de-excitations, is widely used to reduce computational cost. Here, we study the effect of the TDA on exciton binding energies of solids obtained fro...
the foraging behavior of a natural enemy is greatly affected by temperature. the influence ofdifferent constant temperatures on the functional response and prey consumption of the mated female ofneoseiulus barkeri hughes on nymphal stages of tetranychus urticae koch was evaluated. four ambienttemperatures (20, 25, 30 and 35 â± 1â°c) and six prey densities (2, 4, 8, 16, 32 and 64 individuals) we...
در قسمت اول، طراحی و ساخت یک سنسور الکتروشیمیایی با انتخابگری بالا با استفاده ازmolecularly imprinted polymer (mip) به عنوان عنصر شناساگر برای داروی مترونیدازول معرفی شده است. mip انتخابگر نسبت به مترونیدازول وnonimprinted polymer (nip) سنتز شدند وسپس در الکترود خمیر کربن قرار گرفتند. این الکترود برای اندازه گیری مترونیدازول با استفاده از روش cathodic stripping voltammetry به کار برده شد. الکتر...
the green peach aphid,myzuspersicae (hem:aphididae) is a polyphagus aphid species that infects over 400 plants species belonging to 40 different families. the oenopia conglobata contaminata (col.: coccinellidae) is one of the most important predator of orchard pests in iran. in this study, efficiency and predatory of this predatoron green peach aphid m.persicaewas evaluated under laboratory c...
