Single crystalline silver nanoparticles have been synthesized by thermal decomposition of silver oxalate in water and in ethylene glycol. Polyvinyl alcohol (PVA) was employed as a capping agent. The particles were spherical in shape with size below 10 nm. The chemical reduction of silver oxalate by PVA was also observed. Increase of the polymer concentration led to a decrease in the size of Ag ...

A 21-year-old male with a history of Down's syndrome presented with hematuria and right flank pain. Computed Tomography (CT) of the abdomen/pelvis revealed right hydronephrosis and a right-sided pelvic vascular abnormality. Angiography revealed an arteriovenous malformation (AVM) fed by the right superior and inferior vesical arteries and nephrostogram showed a long segment of obstructed distal...

the sequencing batch reactors were developed to treat the actual wastewater from ethyleneglycol/ethylene oxide producing industry. four identical reactors with total and effective liquid volumes of 9and 7 l were operated respectively in parallel. laboratory experiments were conducted with different organicloadings of 500, 1000, 1500 and 3000 g-cod/m3.day and the performance of the reactors was ...

A 6-year-old neutered male German shepherd dog was evaluated for obtundation, blindness, and bilateral exophthalmos. magnetic resonance imaging scan of the brain performed identified an arteriovenous malformation (AVM) with several feeding arterial branches, venous drainage through cavernous sinus. Venous vessels rostral to AVM were severely distended extended into retrobulbar spaces. Liquid em...
