background: ventilator-associated pneumonia (vap) is the most common nosocomial (hospital acquired) infection among patients undergoing mechanical ventilation. it increases mortality rate, duration of mechanical intubated ventilation, and hospitalization in the intensive care units (icus). this review study aims to determine the proper gradient of a hospital bed in preventing vap in patients ho...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
BACKGROUND In patients with aneurysmal subarachnoid hemorrhage, elevation of the head of the bed during vasospasm has been limited in an attempt to minimize vasospasm or its sequelae or both. Consequently, some patients have remained on bed rest for weeks. OBJECTIVES To determine how elevations of the head of the bed of 20 degrees and 45 degrees affect cerebrovascular dynamics in adult patien...
A model of intracranial pressure (ICP) dynamics that uses fluid volumes as primary state variables is presented, along with clinical data for two subjects with elevated ICP. The data includes annotations to indicate the precise timing of clinical changes in cerebral spinal fluid drainage, head of bed elevation, and minute ventilation. The response to changes in the clinical parameters was used ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
abstract autoimmune pancreatitis (aip) is a rare disorder that may be present as common bile duct stricture. the patient was a seventy-year-old man with presentations as recurrent abdominal pain and jaundice, elevated billirobin (bil) and elevated alkaline phosphatase (alkp) in association with the presence of hetrogenesity of the pancreatic head and dilated intra and extra hepatic bile ducts i...
با پدیده نوظهور اینترنت و گسترش روزافزون شبکه های داده نیاز به سوئیچ های با ظرفیت بالا بیش از پیش احساس می گردد. اغلب سوئیچهای پرظرفیت از نوع سوئیچ های با بافر ورودی حافظه مشترک برای نیل ب سرعت بالا می باشند. دسته اول این سوئیچها، بافر ورودی از مشکل hol(head of line blocking) رنج می برند که بازدهی آنها را به 6/58درصد کاهش می دهد.
This study was conducted to investigate the relationship between body shape and environmental factors related to a rivarian ecosystem in Kura barbel (Barbus cyri) of the Sefidrud River basin. For this purpose, a number of 285 specimens were sampled from three rivers with different habitat properties including the Taleghan, Totkabon and Kloraz Rivers. The relationship between body shape (extract...
