An important mechanism for postoperative cognitive impairment after cardiac surgery using cardiopulmonary bypass (CPB) is microemboli. One component of the CPB circuit-the cardiotomy-is a major source of gaseous microemboli because it aspirates significant volumes of air with blood from the operative field and intracardiac chambers. Cardiotomies are either integrated within an open hardshell ve...

Time-series observations were conducted in the Dowleiswaram dam reservoir that was constructed on the largest monsoonal river in India to understand the source of inorganic carbon, and fluxes to the atmosphere. The reservoir stores water during dry period of six months and water increases during the period when Indian subcontinent receives significant rainfall. Significant modification of organ...

In Petroleum Engineering, reservoir management aims to maximise the profit from a hydrocarbon reservoir. Highly nonlinear numerical models, which describe the internal structure of hydrocarbon reservoirs, are used to make reservoir management decisions. These models are aimed at providing accurate predictions of the reservoir behaviour under different scenarios. This requires that the model par...

Pengrowth has targeted East Bodo (Alberta side) and Cosine (Saskatchewan side) for waterflood optimization and subsequent enhanced oil recovery applications. Currently, the most practical EOR technology for this heavy oil reservoir seems to be the polymer flood technology in combination with horizontal wells. Several investigators(1-4) have demonstrated the potential of the polymer flood techno...

Numerical simulation of a geothermal reservoir, modelled as a bottom-heated square box, filled with water-CO2 mixture is presented in this work. Furthermore, results for two limiting cases of a reservoir filled with either pure water or CO2 are presented. Effects of different parameters including CO2 concentration as well as reservoir pressure and temperature on the overall performance of the s...

We report a case and surgical technique of successful sling suspension of insufficient efferent limb of continent urinary reservoir, which has occurred urinary incontinence. A 64-year-old male, who received radical cystectomy with continent urinary reservoir, had been suffered urinary incontinence from the reservoir about one year after surgery. Various procedures, such as the repair of the eff...

in this research, using an expansive channel in plan and along the longitudinal profile, deltaic reservoir sedimentation was studied. sedimentation in bed load governed conditions and delta formation in reservoir environment is a function of various parameters such as: geometrical shape of reservoir, bottom slope, hydrological properties and hydraulic conditions of inflowing stream, sediment lo...

PURPOSE To describe a case of safe placement of an inflatable penile prosthesis reservoir for postoperative erectile dysfunction (ED) with a history of radical cystoprostatectomy with an orthotopic Studer neobladder. MATERIALS AND METHODS A 55-year-old bladder cancer patient, who underwent radical cystoprostatectomy with orthotopic Studer neobladder 2 years prior, suffered from postoperative ...

The quest for efficient and scalable parallel reservoir simulators has been evolving with the advancement of high performance computing architectures. Among the various challenges of efficiency and scalability, load imbalance is a major obstacle that has not been fully addressed and solved. The reasons that cause load imbalance in parallel reservoir simulation are both static and dynamic. Robus...

With the advances in smart well technology, substantially higher oil recovery can be achieved by intelligently managing the operations in a closed-loop optimization framework. The closed-loop optimization consists of two parts: geological model updating and production optimization. Both of these parts require gradient information to minimize or maximize an objective function: squared data misma...
