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...

AIM This study evaluated the efficacy and tolerability of the ketogenic diet (KD) in young Indian children with refractory epilepsy. The changes in biochemical and lipid profile with KD were also assessed. METHODS Children aged 6 months to 5 years who had daily seizures (or at least 7 seizures/week) despite the appropriate use of at least three antiepileptic drugs were enrolled. KD was introd...

There has been a trend away from dorsal fixation of distal radius fractures secondary to a historically higher complication rate. However, the literature on low-profile dorsal plates and titanium implants for the treatment of these fractures is limited. The goal of the current study was to evaluate hardware-related complications and removal rates after open reduction and internal fixation of un...

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 ...

Excessive inflammation is a hallmark of muscle myopathies, including Duchenne muscular dystrophy (DMD). There is interest in characterising novel genes that regulate inflammation due to their potential to modify disease progression. Gene polymorphisms in Selenoprotein S (Seps1) are associated with elevated proinflammatory cytokines, and in vitro SEPS1 is protective against inflammatory stress. ...

The smart grid is a future power network capable of making the power system more intelligent taking advantage of sophisticated information technologies and two-way communication. The information technology allows efficient demand side management which reshapes the power consumption by scheduling the operation of electric devices and equipments in smart homes, buildings, farms, and the like. The...
