One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...

to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...

Lipoamide dehydrogenase was identified in serum and the optimal conditions for its assay at 30 degrees C were defined. The pH optimum in tris(hydroxymethyl)aminomethane buffer is 7.8, and activity is inhibited if buffer concentration exceeds 100 mmol/liter. Saturating concentrations of the substrates NAD+ and lipoamide are 3 mmol/liter and 5 mmol/liter, respectively. Activity is decreased eight...

BACKGROUND Sustained compression is recommended to maximize myocardial and cerebral blood flow during cardiopulmonary resuscitation (CPR) in adults and children. We compared myocardial and cerebral perfusion during CPR in three groups of 2-week-old anesthetized swine using compression rates and duty cycles (duration of compression/total cycle time) of 100 per minute, 60%; 100 per minute, 30%; a...

Aim: The objective of the study was to determine if there is any reduction in periodontal disease in people living in areas where the drinking water contains fluoride in more than optimum levelas compared to its definite proven anti caries activity. Methodology: A survey with 320 patients in two groups of 160 each in Sengattur [4.4ppm] Salem District, Tamil Nadu and Nalgonda [3.5ppm], in Andhra...

CONTEXT This paper describes a very simple, non-threatening method for improving communication and sharing learning points. OBJECTIVE To test whether sharing anonymised reporting of problems and helpful hints is acceptable and useful to staff. DESIGN A pink slip (pinkie) was designed and made available in every clinic venue. All staff were asked to write about any episodes where practice wa...
