hydroforming process in one of the most effective production method, for improving the drawing ratio in sheet metal forming process. this is due to the fact that in hydroforming process, forming takes place using a punch which drives the part forward via a controlled fluid pressure. in this paper, deep drawing hydroforming for circular punch is investigated. different pressure paths are tested ...

the production of oxygen radicals in plants under salinity stress conditions in an the important factor for a diminishing of a photosynthesis and a cause fir a decrease in later vegetative growth. in order to study the effects of antioxidants and salinity stress on photosynthetic characteristics and growth in olive, an experiment was conducted in the research greenhouse of tabriz university in ...

Objective this study was to use Pulp mandibular premolars and derive population-specific equations estimation. Materials Method: A retrospective conducted Department Oral Maxillofacial Pathology, Kantipur Dental College T...

Broadband shock-associated noise (BBSAN) is an important component of supersonic jet for jets at off-design conditions when the pressure nozzle exit different from ambient. Two high-area-ratio under-expanded ratios (NPRs) 3.4 and 4.2 are considered. The correspond to experiment in Laboratory Turbulence Research Aerospace Combustion (LTRAC) Supersonic Jet Facility Monash University. Flow solutio...

OBJECTIVE The no-reflow phenomenon is associated with a worse prognosis at follow-up for ST-segment elevation myocardial infarction (STEMI) patients with a primary percutaneous coronary intervention. To date, there is no effective method to predict no-reflow. The aim of this study was to establish a predictive system to evaluate the risk of no-reflow by integrating multiple types of information...
