Plain abdominal radiographs are commonly requested for acute medical emergencies on patients with non-specific abdominal symptoms and signs. In this study 131 plain abdominal radiographs performed on the day of admission were prospectively analysed. In only 16 cases (12%) the reasons for requests conformed to the recommended guidelines by the Royal College of Radiologists. The reason for the re...

background: ankle fractures, especially those resulting from external rotation mechanisms are associated with injury to the distal tibiofibular syndesmosis. some authors have recommended performing ct scanning after open ankle surgery to evaluate the reduction of syndesmosis. in this current study, we aimed to investigate the sensitivity of plain radiography in diagnosing syndesmosis malreducti...

izeh plain is a sedimentary plain situated at northeastern part at khuzestan province, iran where according to some partial investigations carried out in 2007, 54 settlements from epipalaeolitic and early neolithic ages were discovered there. henry wright, who had explored throughout this settlement before islamic revolution, implies that only 30 percent of piedmonts were completely investigate...

background: rafsanjan -noogh- anar's plain (54°, 52′- 56°, 34′ longitudinally & 29°, 51′- 31°, 31′ latitudinally) is one of the iran's plains located in sub- basin of daranjir desert. anar's plain is located at the lowest part of rafsanjan -noogh- anar's plain. according to the geological and field studies of the area, the presence of west and east mounts and deposits re­sulting from evaporatio...

In this study, low molecular weight heparin modified hepatitis B surface antigen (HBsAg) were prepared to evaluate the effect of coating material for nasal vaccine delivery. The developed formulations were characterized for size, zeta potential, entrapment efficiency, and mucin adsorption ability. Plain HBsAg nanoparticles demonstrated negative zeta potential and LMWP coated nanoparticles showe...

Mature passive films (age > 10 s) were grown in aerated saturated calcium hydroxide solution, at the open circuit, on plain steel and alloys with 9% and 22% Cr, as well as austenitic stainless steels. The materials were commercially produced concrete reinforcing steels. Differences in the polarization of the oxygen reduction reaction were evidenced. Oxygen reduction rates at moderate cathodic p...

Comparison of historic channel migration rates, modern planform conditions, and overall sediment, wood, and flow conditions and interactions for the Quinault River and Queets River in the western Olympic Peninsula, Washington, reveals decadalto century-scale interactions between gravel-bed channels and forested flood plains in temperate maritime environments. The downstream alluvial portions of...

world's coastlines are the most dynamic natural environments and diverse extraordinary and unique processes are active in this area. one of results of these processes is the formation and evolution of alluvial fans and delta. the studied areas include hormoz strait coastal, shour, jalaby and hassan-langi river delta which in the form of a strip with a varying width covers the areas from th...
