Some theoretical aspects of 3-flavour (3f) neutrino oscillations are reviewed. These include: general properties of 3f oscillation probabilities; matter effects in νμ ↔ ντ oscillations; 3f effects in oscillations of solar, atmospheric, reactor and supernova neutrinos and in accelerator long-baseline experiments; CP and T violation in neutrino oscillations in vacuum and in matter, and the proble...

background : propylene glycol (1,2-propanediol, pg) is a commonly used solvent for oral, intravenous, as well as topical pharmaceutical preparations. while pg is generally considered to be safe, it has been known that large intravenous doses given over a short period of time can be toxic. objective: to evaluate the effect of pg in sepsis induced by the bacterial endotoxin lipopolysaccharide (lp...

fusarium wilt of chickpea, caused by f. oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease, fluorescent pseudomonads were isolated from the rhizosphere of chickpea plants in khorasan province by using king,s b medium (kb). antifungal activity of 80 bacterial strains against f. oxysporum f. sp. ciceris was evaluated on kb and p...
