avo analysis is a technique which is widely used in industry and is applied on seismic prestack data. results from changes in seismic wave reflection amplitude versus offset can be used in extracting elastic properties and hence lithology and reservoirs pore fluid identification. before performing avo analysis studies, processing steps should be ensured that changes in reflection amplitude are ...

objectives: to evaluate the effect of two simultaneous protocols in reducing recovery time and assessment of adverse effects of different fluid replacement therapy in management of diabetic ketoacidosis. materials and methods: in this randomized clinical trial study, two standard protocols were chosen to evaluate recovery time and incidence of dka complications. results: 18 subjects who had sev...

many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

avo theory was introduced around 20 years ago. in recent years, this technique was become to a major tool in hydrocarbon sources exploration. by the help of this method with the suitable understanding from underground layers and knowing how to use this technology, quantitative specifications of reservoir can be recognized. avo analysis is a seismic technique that by using of pre-stack data, est...

dense medium cyclone is a high capacity device that is widely used in coal preparation. it is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in dmcs complex. in this article the flow pattern simulation of dmc is performed with computational fluid dynamics and fluent...

avo as a known methodology is used to identify fluid type and reservoir lithology in subsurface exploration. method discussed in this paper, consists of three stages, including: direct modeling, inverse modeling and cross plot interpretation. by direct modeling we can clarify lithology or fluid dependent attributes. analysis performed using both p-p and p-sv attributes. inverse modeling deals w...
