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...

Plain 0.5% bupivacaine 3 ml was compared with plain 0.25% bupivacaine 6 ml for spinal anaesthesia during transurethral surgery in 40 patients. The solutions were injected over 30 s at the L3/4 space with the patient in the sitting position. The patient was kept sitting for 2 min, supine for 5 min and then placed in the lithotomy position. No significant differences were found in onset time, ext...

In this paper, the Artificial Neural Network (ANN) approach is applied for forecasting groundwater level fluctuation in Aghili plain,southwest Iran. An optimal design is completed for the two hidden layers with four different algorithms: gradient descent withmomentum (GDM), levenberg marquardt (LM), resilient back propagation (RP), and scaled conjugate gradient (SCG). Rain,evaporation, relative...

Groundwater is one of the most important water resources especially for irrigation in the east of Iran. So, it is important to note its water quality variation for deciding to manage it. To this end, the study were done to zone Birjand plain located at latitude between 32˚ 30’-33˚ 00’ N and longitude between 58˚ 45’-59˚ 41’ E. In order to achieve this goal, the required layers, Sodium adsorptio...
