background demand for icu beds is exceeding its supply. since the sources are limited in some centers, it is necessary to design a model to identify the patients who benefit more from icu beds. objectives the present study aimed to develop a model to prioritize adult patients according to their clinical indications by a three rounded delphi method study. patients and methods in this study, 22 p...

background critically ill patients under mechanical ventilation require frequent suctioning of airway secretion. closed suction permits suctioning without disconnection from ventilator; so it might decrease hypoxemia and infection rate. objectives this study aimed to evaluate the effect of closed tracheal suction system (ctss) versus open tracheal suction system (otss). patients and methods thi...

today, vehicular ad-hoc network between automobiles has been accepted by the public, and many people are interested in exchanging information with other vehicles as well as with roadside equipment while driving. when a number of vehicles want to access to the data stored in rsu ,the priority of servicing comes into face .in this case, some  methods, such as d*s, d*s/n,  have been presented so f...

motor units (mus) reflect the function of the central nervous motor system. thus, the estimated mu number is a good option to investigate the functional movement disorder in the parkinson’s disease (pd). the purpose of this study was to compare the estimated mus number in the medial gastrocnemius (mg) muscle of the normal rats and those with the parkinsonism. the mg muscle of two age-matched gr...

background and purpose: considering the obstacles against the implementation of ethical decisions by nurses, experiencing moral distress is one of the major issues in this profession. moral distress could have negative effects on the physical and mental health of nurses, quality of patient care and performance of health organizations. given the importance of addressing moral distress in working...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

In order to assess the satellite data for soil investigation, ASTER digital data 20 June 2006, field study and phisiochemical properties of soil, were analyzed. All landcover classes including soils are classified based onmorphological and physico-chemical characteristics. Images were geocorrected and photomorphic units were selected based upon visual interpretation and sampling in study area. ...

abstract background: most of the patients admitted in the intensive care units (icus) require an endotracheal tube and mechanical ventilation. in order to clear and maintain patency of the airways, endotracheal suctioning is required. therefore, the least detrimental way of endotracheal tube suctioning which can diminish the complications should be selected. the present study aimed to compare t...

abstract background: while critical care nurses are vulnerable to burnout because of the complex nature of patients’ health problems, working in critical care areas has become even more complicated by shift working schedules. this study aimed to determine the relationship between fixed and rotating shifts and burnout in a sample of critical care nurses working in critical care areas. materials ...
