In many reservoirs, after water flooding, a large volume of oil is still left behind. Hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.In the present work, the effects of injection rate and the temperature of the injected water were surveyed by using core flooding apparatus. Water flooding was perf...

the effect of short term usage of gnrh antagonist as pretreatment on superovulation in goats was evaluated. statistical analysis was performed using t-test and showed that usage of gnrh antagonist as pretreatment can improve number of recovered embryos (p0.05). this study showed that usage of gnrh antagonist can improve superovulatory response in term of embryo recovery in goats .this study sho...

the lead and zinc sample from goosh-e-fill mine with 2.4%pb, 8.0%zn and 10.0% fe, was used in different flotation experiments to recover lead and zinc minerals. the valuable minerals in prepared sample were oxidized and the results showed that the lead minerals floated at ph= 9.5 and 11.5, probably it can be due to existence of two or more types of lead minerals. the best result was achieved fo...

a typical iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. the modeling was carried out by using a fine-scaled eclipse model in the single porosity mode (the fractures were explicitly modeled). the model was extended to a stack of 6 matrix blocks to understand block-to-...

Formation of inclusion bodies in bacterial hosts poses a major challenge for large scale recovery of bioactive proteins. The process of obtaining bioactive protein from inclusion bodies is labor intensive and the yields of recombinant protein are often low. Here we review the developments in the field that are targeted at improving the yield, as well as quality of the recombinant protein by opt...

Various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. The objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

Including protein in a carbohydrate solution may accelerate both the rate of glycogen storage and the restoration of exercise capacity following prolonged activity. Two studies were undertaken with nine active men in study A and seven in study B. All participants performed 2 trials, each involving a 90 min run at 70% VO2max followed by a 4 h recovery. During recovery, either a 9.3% carbohydrate...
