Background: Endotracheal tube cuff pressure must be maintained in safe range. Many factors could be affecting on endotracheal tube cuff pressure in patients on mechanical ventilation. Patients undergoing mechanical ventilation (MV) in critical care settings require changing position for different reasons. The aim of this study was to determine the effect of changes in body position and head of ...
This paper addresses the dynamic path planning for two mobile robots in unknownenvironment with obstacle avoidance and moving target tracking. These robots must form atriangle with moving target. The algorithm is composed of two parts. The first part of thealgorithm used for formation planning of the robots and a moving target. It generates thedesired position for the robots for the next step. ...
In the present work, first an analytic relation for position-dependent effective mass in a quantum rod is obtained. Then, the effect of position-dependent effective mass on the intersubband optical absorption coeffcient and the refractive index change in the quantum rod is examined. Our numerical calculations are performed using both a constant effective mass and the position-dependent effect...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
Background: Feeding intolerance is a major concern in preterm infants. Appropriate position during feeding is one of the interventions that nurses can exploite in order to improve the feeding tolerance in preterm infants. Aim: Comparison of the effect of nutrition in the kangaroo mother care and supine position on gavage residual volume in preterm infants. Methods: Thisrandomized single-blind c...
Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel processing technique is proposed and the wavelet transform is used to eliminate the impact of sp...
Background: Diagnostic cardiac catheterization is a common procedure in coronary artery disease. Patients’ movement and activities are limited because of potential risks; therefore, they need bed rest. The current study aimed at investigating the impacts of changes in body position and earlier ambulation on comfort, bleeding, and ecchymosis after the diagnostic cardiac catheterization. M...
Accurate co-receptor tropism (CRT) determination is critical for making treatment decisions in HIV management. We created a genotypic tropism prediction tool by utilizing the case-based reasoning (CBR) technique that attempts to solve new problems through applying the solution from similar past problems. V3 loop sequences from 732 clinical samples with diverse characteristics were used to build...
in an attempt to investigate the relationship of birth rank and family size with the incidence of neurosis in an iranian culture, case notes of 1029 schizophrenic patients as (497 males and 532 females) referred to psychiatric clinic for insured workers were studied. the incidence of neurasis appeared to be significantly more frequent among the first-half position of birth rders in the familie...
ABSTRACT The effect of position on the spread and the onset time of epidural anesthesia has not been well documented. This study is undertaken to assess the effect of modified trendelenburg position on the spread of epidural anesthesia for cesarean section. 739 parturients were undergone epidural anesthesia for elective or emergent sesarean section. They were divided into 2 groups in a...
