In order to investigate the effects of artificial substrates (vertical surface of polypropylene fabrics) on cultured shrimp, we reared 28-day old Litopenaeus vannamei post-larvae (PL28) intensively for 90 days at a density of 510 shrimp/m2 in each of 8 tanks. Two tanks containing no artificial substrate were a control group, and 1, 3 and 5 artificial substrates were present in other 6 tanks. T...

abstract eating and drinking are essential for life. there are clinical situations that artificial hydration is necessary. for dying patients artificial hydration looks useless and in many conditions could even be harmful (e.g. pulmonary edema in hypoalbuminemic patients). in our medical culture artificial hydration is a symbol of care to the patient and withholding it, is a very emotive issue,...

This article presents the seismic assessment and retrofit design of an existing old building in Greece great regional importance. The Building is “Administration Kalamata” located city Kalamata, capital Messinia Prefecture. Building, largest city, a seven-floor reinforced concrete (r/c) structure with basement built 1974. procedure based on provisions EN 1998-3 code Greek for structural interve...

this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...

Earthquake time history records are required to perform dynamic nonlinear analyses. In order to provide a suitable set of such records, they are scaled to match a target spectrum as introduced in the well-known design codes. Corresponding scaling factors are taken similar in practice however, optimizing them reduces extra-ordinary economic charge for the seismic design. In the present work a ne...

Groundwater is among the most important resources of drinking water supply ofthe worldwide population. Use of recharge area is one of the methods for artificiallyrecharging groundwater. Selection of suitable sites for artificial recharge is very importantand must be carried out accurately. There are different types of land use, only rangelandsare appropriate for artificial recharge because of t...

context studies show that despite the role of mouth care in preventing ventilator-associated pneumonia, there is no high quality evidences for it. this study reviewed the literature related to mouth care in patients receiving mechanical ventilation. evidence acquisition pubmed, ovide, elsevier, proquest, iranmedex, sid, and magiran databases were searched using key terms such as oral care, mout...
