the pea aphid, acyrthosiphon pisum (harris) is one of the most important pests of pea throughout the world.host stage preference under choice and no-choice tests and age-specific functional response of praon volucre (haliday) parasitizing a. pisum were investigated. the experiments were carried out under laboratory conditions at 25 ± 1 °c, 60 ± 5% rh and a photoperiod of 14: 10 h (l: d). functi...

background: stimulants addition and abuse can cause some functional and morphological changes in the normal function of glands and hormones. methamphetamine as an addictive stimulant drug affects the hypothalamic-pituitary-adrenal (hpa) axis and consequently makes some changes in the psychological state of the drug users. the present study aims to examine the relationship between plasma levels ...

Linear-response time-dependent density-functional theory (TDDFT) can describe excitonic features in the optical spectra of insulators and semiconductors, using exchange-correlation (xc) kernels behaving as $-1/k^{2}$ to leading order. We show how excitons be modeled real-time TDDFT, an xc vector potential constructed from approximate, long-range corrected kernels. demonstrate for various materi...

common pistachio psylla, agonoscena pistaciae burckardt and lauterer (hemiptera: aphalaridae) is one of the economical pest among the pistachio orchards. the adonis' ladybird, hippodamia variegata (goeze) (col: coccinellidae) is one of the most prominent coccinellid predator in pistachio orchards. it is omnivorous and feed on aphids and psylla. functional response studies using a suitable ...

BACKGROUND Emergent studies show that similar to other substances of abuse, cue-reactivity to cannabis is also associated with neural response in the brain's reward pathway (Filbey et al., 2009). However, the inter-relatedness of brain regions during cue-reactivity in cannabis users remains unknown. METHODS In this study, we conducted a series of investigations to determine functional connect...

background: chronic daily headache (cdh) has gained little attention in functional neuro-imaging. when no structural abnormality is found in cdh, defining functional correlates between activated brain regions during headache bouts may provide unique insights towards understanding the pathophysiology of this type of headache. methods: we recruited four cdh cases for comprehensive assessments, in...

land mines are one of the tragic problems to human security in many countries. among many techniques suggested detecting landmines, plant-based detectors can be used as a reliable tool for unexploded ordnance detection. this study was conducted to determine different concentrations effect of trinitrotoluene (0, 5, 10, 15, 20, 30, 45 and 60 ppm) on germination and early seedling growth of 6 spec...
