the density of state and the natural bond orbital calculations were carried out to study theoxidation of co on au14 nano cluster through two different mechanisms and determining the bestmechanism for the reaction. chemisorption of o2 and co on the nano cluster led to change in energy,density of state and its thermodynamic properties. we calculated the energy band gap between thehighest occupied...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

The term "orbital tumors" comprises a wide variety of lesions that often share the same cardinal clinical finding (exophthalmos) and clinical history. Age at presentation, associated ophthalmological findings, and radiological features, however, provide invaluable information as to the possible histological type of tumor. The present article serves as an introductory overview regarding the path...

We introduce six quantities that generalize the equinoctial orbital elements when some or all perturbing forces act on propagated body are derived from a disturbing potential. Three of define non-osculating ellipse plane, other two fix orientation reference frame, and last allows one to determine true longitude body. The Jacobian matrices transformations between new position velocity explicitly...

Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer after papillary carcinoma. It usually grows slowly and is clinically indolent; but rarely, its aggressive forms with distant metastases can occur. We report here an uncommon case of bilateral orbital metastasis of FTC. A 70-year-old woman present...

purpose: to determine the prevalence of intraocular injuries in patients with blow-out fracture and also to evaluate the etiologic mechanism of orbital blow-out fractures methods: this study is a consecutive case series analysis of 116 patients with orbital blow-out fractures. the patients were visited by an ophthalmologist within 24 hours of trauma. results: ninety-one men and twenty-five wome...
