Psikiyatri ve sinema, yalnızca birbirlerini yaratıcı bir şekilde tamamladıkları için değil, aynı zamanda hem film yapımcılarının de psikiyatristlerin mesleklerinden yararlanan, didaktik kategorilere profesyonel itici güçlere karışan karşılıklı etkilerin fırsatı olarak ayrılmaz bağlantılıdır. 
 Sinema hareketli görüntülerin kullanımıyla, insan zihninin gerçek işleyişini yeniden işleyebilir....
Diagnosis and quantification of aerotitis media were performed using a modified commercially-available tympanometer under hypobaric conditions. Subjects were 22 males and 9 females, 22-43 years of age, who were tested in each ear with the tympanometer prior to and after exposure, sequentially at the barometric pressure plateaus of 706, 656, 609, 586, 564, and 522 mm Hg, and following an induced...
In this paper, some results are provided for minimum time roll about velocity vector maneuvering with thrust-vectoring and aerodynamic control in effect. The mathematical model for attitude motions of the aircraft is developed. First order necessary conditions for optimality using Pontryagen principle is applied, and the existence of an extreme family of solutions for the maneuver is shown. Mul...
In order to determine the effect of Valsalva maneuver and head rotation on the internal jugular vein (IJV) diameter and cross-sectional area and overlap with the carotid artery (CA) and find the best technique for safe cannulation of the IJV and decrease the risk of CA puncture, the diameter of both the IJV and the CA and percentage of overlap between the two vessels and cross-sectional are...
background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...
Electrical Engineering (ABSTRACT) Recent accomplishments in link-level and radio technologies have significantly improved the performance of wireless links. Wireless mobile ad hoc networks, however, typically only take limited advantage of these enhancements. In this research, the medium access control protocol and ad hoc routing protocol are extended to take advantage of radios offering multiu...
background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp us...
Maneuverability is an important aspect of marine vehicle design. With the development and utilization of ocean resources, maritime transportation is becoming increasingly busy. Stopping ability has great effect on the safety of ship maneuvering for those large ships. Therefore, it is necessary to study the behavior of the ship during the stopping maneuver to ensure the safety of navigation. In ...
OBJECTIVE To assess the safety and efficacy of a recruitment maneuver, the Open Lung Tool, in pediatric patients with acute lung injury and acute respiratory distress syndrome. DESIGN Prospective cohort study using a repeated-measures design. SETTING Pediatric intensive care unit at an urban tertiary children's hospital. PATIENTS Twenty-one ventilated pediatric patients with acute lung in...
