the present study aimed to compare the effectiveness of cognitive-behavioral therapy (cbt) and eye movement desensiti­zation and reprocessing (emdr) in reducing ptsd symptoms severity among iranian children 20 months after the 2008 qeshm earthquake. this study follows an experimental design with randomized pre-test post-test to control the internal and external validity of the study. in this st...

In 1988, J.R. Faulkner has given a procedure to construct an octonion algebra on a finite dimensional unitary alternative algebra of degree three over a field K. Here we use a similar procedure to get a quaternion algebra. Then we obtain some conditions for these octonion and quaternion algebras to be split or division algebras. Then we consider the implications of the found conditions to the u...

Deadlock detection is one of the most discussed problems in the literature. Although several algorithms have been proposed, the problem is still open. In general, the correct operation of an algorithm depends on the requirement model being considered. This article introduces a deadlockdetection algorithm for the OR model. The algorithm is complete, because it detects all deadlocks, and it is co...

Background: Overcrowding is an important problem for outpatient services in healthcare facilities. Patient flow analysis (PFA) is a useful method for identifying inefficiencies in and facilitating patient flow. Objective: PFA was used to estimate patient wait time and determine how different clinical disciplines impact wait times in the studied hospital.<...

In the asynchronous PRAM model processes communicate by atomically read ing and writing shared memory locations This paper investigates the extent to which asynchronous PRAM permits long lived highly concurrent data struc tures An implementation of a concurrent object is non blocking if some op eration will always complete in a nite number of steps it is wait free if every operation will comple...

This controlled study evaluated the relative efficacy of Prolonged Exposure (PE) and Eye Movement Desensitization and Reprocessing (EMDR) compared to a no-treatment wait-list control (WAIT) in the treatment of PTSD in adult female rape victims (n = 74). Improvement in PTSD as assessed by blind independent assessors, depression, dissociation, and state anxiety was significantly greater in both t...

The paper investigates train scheduling problems when prioritised trains and non-prioritised trains are simultaneously traversed in a single-line rail network. In this case, no-wait conditions arise because the prioritised trains such as express passenger trains should traverse continuously without any interruption. In comparison, non-prioritised trains such as freight trains are allowed to ent...

OBJECTIVES There are unique challenges to enrolling patients in emergency department (ED) clinical research studies, including the time-sensitive nature of emergency conditions, the acute care environment, and the lack of an established relationship with patients. Prolonged ED wait times have been associated with a variety of adverse effects on patient care. The objective of this study was to a...

There is no doubt that the vast majority of delayed diagnoses in malignant disease are due to fear and ignorance on the part of the patient. This delay is appalling, as the figures from the Registrar General 19-7 show. The mean delay in cancer of the breast is 6.2 months but 17.3 per cent wait over two years. In the cervix uteri it is 5.7 months and 8.4 per cent wait over two years, and for rec...
