this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
abstract background: accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences. one of the most common methods of airway clearance is endotracheal suctioning. in order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy techniques can be used at the time of expirat...
Title of dissertation: EXPERIMENTAL AND THEORETICAL INVESTIGATION OF OIL RETENTION IN A CARBON DIOXIDE AIR-CONDITIONING SYSTEM Jun-Pyo Lee, Doctor of Philosophy, 2003 Dissertation directed by: Professor Reinhard Radermacher Department of Mechanical Engineering In a closed loop vapor compression cycle, a small portion of the oil circulates with the refrigerant flow through the cycle components w...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Diverticulosis of the main bronchi, not associated with other organ abnormalities, developed in a 12 year old child. This abnormality caused recurrent bronchopneumonia in the lung with the main bronchi diverticulosis. Fibreoptic bronchoscopy helped to locate the lesion and selective bronchography, with injection of contrast medium through the suction channel of the fibreoptic bronchoscope, show...
The application of inductively coupled plasma mass spectrometry (ICP-MS) to forensic chemistry was studied. The developed method, air-segmented sample injection (ASSI) coupled with ICP-MS, allowed the determination of about 25 elements at the sub-ppb level with only 0.2 ml of a sample solution. The optimum sample flow rate was found to be 0.4 ml min(-1), along with a sample suction time of 30 s...
