Abstract Background Laparoscopic cholecystectomy is the gold standard treatment for symptomatic cholelithiasis including pancreatitis. Symptomatic gall stones patients have up to 20% risk of having common bile duct (CBD) too. Although, guidelines been laid down management suspected CBD stones, in practice there a lot variability and lack standardisation. The waiting list Magnetic resonance chol...

The Electron Gamma Shower (EGS) Code System at SLAC is designed to simulate the flow of electrons, positrons and photons through matter at a wide range of energies. It has a large user base among the high-energy physics community and is often used as a teaching tool through a Web interface that allows program input and output. Our work aims to improve the user interaction and shower visualizati...

Using a lysine-specific cleavable cross-linking reagent ethylene glycolbis(sulfosuccimidylsuccinate) (Sulfo-EGS), we studied conformational motion in the surface loops of Escherichia coli FepA during its transport of the siderophore ferric enterobactin. Site-directed mutagenesis determined that Sulfo-EGS reacted with two lysines, K332 and K483, and at least two other unidentified Lys residues i...

EGS is a very common Monte Carlo code, used in the simulation of Nuclear Medicine devices. Simulation techniques are particularly useful, in order to optimize collimator configuration and camera design in Single Photon Emission studies. Using the EGS code, users must define the geometry where particles are transported. This can be both a very hard task and a source of inefficiency, especially i...

BACKGROUND Racial disparities in surgical care are well described. As many minority patients are also uninsured, increasing access to care is thought to be a viable solution to mitigate inequities. The objectives of this study were to determine whether racial disparities in 30-/90-/180- day outcomes exist within a universally insured population of military-/civilian-dependent emergency general ...

BACKGROUND Aerosolization of seafood and subsequent inhalation, during processing is a potential high-risk activity for allergic respiratory disease. OBJECTIVES To quantify total thoracic particulate, protein concentration and specific fish (pilchard, anchovy) antigen concentrations in fish processing plants; to determine the correlation between these exposure metrics; and to identify the maj...

Heat recovery from an enhanced geothermal system (EGS) is a complex process involving heat transport in both fracture networks and rock formations. A comprehensive understanding of the ability to model underlying mechanisms important for success EGS commercialization but remains challenging practice due generally insufficient characterization reservoirs. In present study, we analyze extensively...

Water injection and Enhanced Geothermal System (EGS) technologies have been used to exploit heat resources from geothermal reservoirs. Detecting spatial temporal changes in reservoir physical properties is important for monitoring condition due water EGS. Here, we determine high-resolution models of the three-dimensional P wave velocity attenuation (Vp Qp) structures between years 2005 2011 nor...

the knee bracing steel frame (kbf) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. rather than the beam-column joint, one end of the diagonal brace in kbf is attached to the knee element. indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...

Human activities, such as fluid injection as part of the stimulation of an enhanced geothermal system (EGS) for heat and power production, can cause damaging earthquake ground motions. A difficulty in quickly settling or rejecting insurance claims to the policy of the operator of the EGS is the lack of ground truth on the observed shaking at sites of reported damage. To overcome this problem a ...
