dyspepsia is a common gastrointestinal symptom reported in 2.9-29% of the adult iranian population. this symptom usually results from functional disease, but in one-third of cases an organic cause such as peptic ulcers, esophagitis, and in less than one percent gastric cancer can be found. the timing of an endoscopic evaluation, the value of acid reducing agents, herbal medicine and the role of...

hypertonicity is the most common type of cerebral palsy consists of 85% of the affected children. it has a very complex nature making intervention and management very difficult. this article tries to make reader familiar with various types of intervention and introduce a new intervention process to help clinicians decide better. literature was reviewed with two criteria including: identifying v...

t-condylar fracture of distal humerus in young children is very rare. pure physeal fractures of the olecranon are also rare. we report on an extremely rare case of concomitant ulecranon fracture, ipsilateral segmental humerus and intercondylar humerus fracture (type iii) in a skeletally immature patient.

in the present paper, the deformation zone of the ecae (equal channel angular extrusion) process was investigated using the upper bound theorem. for this purpose, the shape of the streamlines in the deformation zone was assumed to be cubic bezier curves. then, the force required for the ecae process was optimized with regard to the parameters defining the shape of streamlines by the upper bound...

due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. in thecurrent study, nine sandstone samples from the upper red formation (specified by the letters a, b, c, cg, s, s1, sh, tr and min)were studied from a petrophysical point of view and their durability was evaluated. then, their suitability as building stones wasassess...

upper devonian sediments of the kuh-e zard area northwest of zefreh, central iran, arecomposed mainly of brown and grey limestones with sandstone and shale intercalations. they contain tracefossils such as chondrites isp., diplocraterion parallelum, fustiglyphus annulatus, lockeia isp., phycodesisp., and taenidium barretti. these trace fossils indicate a shallow marine environment

prediction of the outcome and severity of acute upper gastrointestinal bleeding (ugib) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. recent international recommendations endorse using scoring systems for management of non-variceal ugib patients. to date, different scoring systems have been developed for predicting the risk of 30-day mo...

the nayband formation was measured and sampled in parvadeh area, southern tabas city. in this area, this formation has a thickness of 1410 m, dividing into four members, namely gelkan, bidestan, howz-e-sheikh and howz-e-khan. a total 573 samples were treated for palynological analysis, and only 120 samples were productive. a total of 57 miospore taxa and 11 plant macrofossil were encountered. b...

precision forging process is widely used for the production of spur gears due to its advantages such asimproved strength and surface finish, little waste of materials and reduction in the machining time ofthe gear. an important aspect of precision forging process is the load required to perform the processsuccessfully and design the forging tools. in this research, a new kinematically admissibl...
