UNLABELLED Supracondylar humerus fractures are common pediatric injuries. Little is known about the risk factors for repeat operative procedures. A retrospective chart review of 709 patients treated for a displaced supracondylar humerus fracture was performed to identify risk factors for return to the operating room during the initial post-operative period. Deviations of routine fracture care w...

OBJECTIVE To find the causes of operating room cancellation in patients attending preoperative anaesthesia clinic and scheduled for surgery at our institution. METHODS This audit included all those patients who presented to the pre anaesthesia clinic with their surgeries planned in the main operating rooms of our hospital. The duration of this audit was two months. Cancelled cases were identi...

the steady state effect of vertical fins is assessed on a photovoltaic/thermal solar air heater having a double pass configuration in which fins are placed in the lower channel perpendicular to the direction ofair flow. air passes through the upper channel of the air heater and before passing in the opposite direction through the lower channel. the effects of design, climatic and operating para...

concurrency control is one of the important problems in operation systems. various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. this paper presents a survey of the current methods for controlling...

chemical vapor deposition (cvd) is one of the most popular methods for producing carbon nanotubes (cnts). the growth rate of cnts based on cvd technique is investigated by using a numerical model based on finite volume method. inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal cvd reactor at atmospheric pressure. in thi...

The diversity of operating systems offer users more options to choose. The point of this study is to understand the aspects that affect the decision with respect to user’s background and what core factors drive their choice of operating system. There are five elements that need to be considered before making a decision. The following factors and model were developed based on literature reviews ...
