nanoporous graphene which is used as nanosorbent was synthesized by chemical vapor deposition method via porous zinc oxide nanocatalyst. the reaction was carried out using methane as the carbon source and hydrogen as the carrier gas in a ratio of 4:1 at the temperature ranging 900-1050°c for 2-50 min. the product was characterized by scanning electron microscopy, transmission electron microscop...

Aneurysm volume/virtual column volume (AV/CV) ratio, calculated from measurements derived from reconstructed images based on rotational three-dimensional digital subtraction angiography (3D-DSA), was investigated as a predictor of the success of intraaneurysmal embolization in 20 unruptured wide-necked internal carotid artery aneurysms treated by Guglielmi detachable coils. AV and neck area wer...

Environmental stresses are the most important factors that reduce plant growth in stages of development. The presence of aluminum in acidic soils as an environmental stress has an impact on different parts of the plant and reduces root growth, water absorption and nutrients and increases susceptibility to drought.  In order to evaluate the effect of aluminum stress levels on wheat at germinatio...

AIMS To study the relation between optic nerve head topography (Heidelberg retina tomograph, HRT) and disc area, visual field index mean defect (MD), and intraocular pressure (IOP), and to see whether change in HRT parameters is associated with change in MD in a prospective follow up. METHODS 80 consecutive patients (69 patients with exfoliation glaucoma and 11 with ocular hypertension combin...
