in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

background: cholangiocarcinoma is an invasive biliary malignancy with poor prognosis. diagnostic accuracy of conventional methods is low which is mainly due to the specific anatomy of the disease. the aim of this study was to evaluate the diagnostic value of biochemical profile and tumor marker of the bile in patients with malignant cholestasis compared to that of choledocholithiasis. methods: ...

background: management of multiple sclerosis (ms) is based on the usage of immunosuppressive and immune-modulating medications. cytokines play an important role in the pathogenesis of ms. objective: to evaluate the effects of rapamycin on the concentrations of th1/th2/th17 serum cytokines in patients with ms. methods: six patients with relapsing remitting ms as a case group and 6 healthy indivi...

present study examines whether there is any beneficial effect of magnetized water application on seedling emergence of maize seeds. water from various sources like tap water, saline water (1,500 ppm), canal water, and sewerage water was treated magnetically by passing it through 235 mt magnetic fields at 3 lpm flow rate. seeds were soaked in water for 24 hours and planted in sand culture. numbe...

We have had this study to evaluate the clinical profile of target-controlled infusion-based anesthesia using remifentanil and propofol. 116 ASA I-II patients undergoing elective laparoscopic cholecystectomy (LCH) were enrolled. TCI Remifentanil was set at 8 micrograms. L - 1 as target and TCI propofol at 4 mcg/ml throughout the whole procedure. The hemodynamics during induction of anesthesia an...

The RIES-KOA e-voting system was used in the Netherlands as an additional system for the elections by expatriates for the Tweede Kamer (roughly: the Dutch House of Commons) elections in 2006. Although the system has been used in other elections in the Netherlands as well, there have been few independent evaluations of the system. In this paper, we apply the recently proposed Protection Profile ...

Ciguatoxins (CTXs) are a group of marine biotoxins, consisting over 30 different congeners that can contaminate food webs. Generally, the molecular structures among known variable by geographical region (i.e., ocean basin) and vector species. Limited information is available regarding CTX profiles or within species their capture regions. Within this study, an in-depth investigation based on sem...
