OBJECTIVES to study the physiological changes, as well as the psychosedative and analgesic effects of nitrous oxide, in experimental conditions. STUDY DESIGN 101 dental students volunteers participated in a single nitrous oxide sedation session without dental treatment. Signs and symptoms were registered during and after the procedure. Pulse rate and hemoglobin oxygen saturation were monitore...
Background & Aim: Nowadays, mechanical ventilators are being used for some patients in ICUs due to various physiological and clinical causes. Keeping endotracheal tube clean and open is necessary in order to improve the patient;aposs oxygenation. This study aimed to investigate the effects of open and closed system endotracheal suctioning on vital signs of patients in ICU. Methods & Materials:...
Abstract Estimation of water saturation, S w , in shaly sandstone is an intricate process. The surface conduction clay minerals adds up to the electrolyte pore spaces, thus generating high formation conductivity that overshadows hydrocarbon effect. In each resistivity-based saturation model, key parameter factor, F which typically derived from Archie’s Law. Referring a log–log plot between fact...
Propoxur is a non-systemic insecticide which was introduced in 1959. It is used against mosquitoes in outdoor areas, against flies in agricultural settings, against fleas and ticks on pets, as an acaricide, on lawns and turf for ants, on flowering plants, and in private dwellings and public buildings. However, nontarget organisms such as honey bees, birds and fish have sensitive toxicity respon...
Platychaete aucheri is one of the exclusive and important rangeland species in the south of the country that has an important role in animal nutrition. In this study, using a generalized increase model, the pattern of response of this species to the slope of soil and topographic factors in its habitats in the province Hormozgan was identified and for this purpose, three regions of Bastak, Sirma...
