Abstract Shunting of trains is a task that requires meticulous adherence to all steps guarantee safety for everyone involved during and after the procedure. These are currently taught using classical teaching materials, such as printouts, videos training by experienced supervisors. However, due limited availability locomotives, hours manpower, shunting operation becomes challenging in real life...

Abstract Background Contrast-enhanced transcranial duplex (c-TCD) might be more sensitive than transesophageal echo (TEE) for detection of right to left shunting (RLS), which misses some cases with substantial RLS and valuable prediction recurrent stroke or transient ischemic attack in patients PFO. Our aim is detect sensitivity specificity contrast-enhanced TCD among patent foramen ovale (PFO)...

Shunting work on sorting wagons is carried out steeper profiles and requires the operation of shunting diesel locomotives a higher power. Many operations use double traction in conditions highly outdated fleet locomotives. However, technology operating two substantiation its scope application. In this article, using example station “X”, disbanding trains from hump investigated ways: first exist...

abstractthe valves of right horn of systemic venous sinus are prominent structures within the right atrium during early embryonic period. involution of these structures may not be complete, resulting in a spectrum of anatomical presentations such as cyanosis. a full-term male neonate referred to our hospital for precise evaluation of severe cyanosis on the first day of life. echocardiographic e...

Pulmonary overflow (PO) is a common finding in left-to-right shunting congenital heart diseases (CHD). B-line artifacts are seen on lung ultrasound the presence of extravascular water.

OBJECTIVES The purpose of this retrospective study was to assess long-term outcome of children after surgical closure of a ventricular septal defect (VSD). MATERIAL AND METHODS Between January 1992 and December 2001 a consecutive series of 188 patients (100 females) were operated for closure of a VSD. Temporary tricuspid valve detachment (TVD) was applied in 46 patients (24%) to enhance expos...

Operative Mortality Following Carotid Endarterectomy To the Editor: I read with great interest the editorial by Dr. Gary G. Ferguson in the May-June 1982 issue of STROKE, Volume 13, p. 287, entitled "Intraoperative Monitoring and Internal Shunts: Are They Necessary in Carotid Endarterectomy?". I was dismayed, however, by the manner in which he displayed our data in the table using his reference...

A CMOS imager based on a novel mixed-mode VLSI implementation of biologically inspired shunting inhibition vision models is presented. It can achieve a wide range of image processing tasks such as image enhancement or edge detection via a programmable shunting inhibition processor. Its most important feature is a gain control mechanism allowing local and global adaptation to the mean input ligh...
