abstract background: the aim of this study was to compare changes in pain, oxygenation, and ventilation following endotracheal suctioning with open and closed suctioning systems in post coronary artery bypass grafting (cabg) patients. materials and methods: 130 post cabg mechanically ventilated patients were randomly allocated to undergo either open (n = 75) or closed (n = 55) endotracheal suct...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
چکیده: مقدمه: یک قالب نگاره ای منفی از وضعیت دهانی- دندانی بیمار است که کست ها به عنوان یک رکورد دایمی از روی آن ساخته می شوند. دقت قالب دقت کست را تحت تاثیر قرار می دهد و یک قالب دقیق برای ساخت یک پروتز با حداکثر تطابق ضروری می باشد. کاهش این عدم تطابق هدف کلی در علم پروتز و ایمپلنت های دندانی است. هدف از این مطالعه نیز بررسی تاثیر تکنیک ها و مواد قالب گیری بر عدم تطابق عمودی بریج های سه واحد...
Background: Nowadays, due to an increase in patients require intensive care, application of mechanical ventilation and endotracheal tube is necessary. In order to Keeping an open airway, endotracheal suctioning is necessary. Select the appropriate suction method can reduce the severe complications. The aim of this study is comparing the efficacy of open and closed suctioning on heart disrhythmi...
This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...
conclusions ip injection of cb1 receptor antagonist might have an anxiogenic profile in rat, whereas calcium channel blocker attenuated the anxiogenic effect of am251. our results suggest that there is an interaction between functions of l-type ca2+ channels and cannabinoid system in anxiety. background the elevated plus-maze (epm) has been broadly used to investigate anxiolytic and anxiogenic ...
on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
