Endoscopic Management of Perforation of Right Hepatic Duct Following Non-Surgical Abdominal Trauma

Isolated bile duct injuries after blunt abdominal trauma are rare. Surgery is the usual mode of treatment. We report a patient with a right hepatic duct injury following blunt abdominal trauma who was managed successfully by endoscopic papillotomy

Effect of Nozzle Divergence Angle on Plume Expansion In Outer-Space Conditions

We carry out numerical simulations to investigate the effect of nozzle divergence angle on back flow of plume expansion into rarefied atmosphere. Results are obtained using open source compressible computational fluid dynamics (CFD) solver. Non-equilibrium slip and jump boundary conditions for velocity and temperature are implemented to capture rarefaction rarefaction effects in the slip flow regime. The solver has been validated with the experimental data for a nozzle flow in the slip flow regime. We explore the non-linear non-equilibrium gas flow physics of a supersonic jet expansion. We report results of pressure, heat and drag coefficients for different divergent angles ( 12 0 , 15 0 and 20 0 ) at 80 km altitude conditions. The slip based results for heat loads significantly under-predict the no-slip ones, while for pressure and drag coefficients, deviations are found to be minute. It is noticed that thrust coefficient of nozzle increases with increase in divergence angle, however, nozzle with divergent angle of 15 0 led to minimum drag and heat transfer load on the critical region. The current study is important from the perspective of the overall aero-thermodynamic design of a typical supersonic rocket model operating under rarefied conditions

Study on High Energy Propellant Waste in the Processing of Fired Clay Bricks

Utilisation of propellant waste in fabrication of bricks is not only used as efficient waste disposal method but also to get better functional properties. In the present study, high energy propellant (HEP) waste additive mixed with soil and fly ash in different proportions during manufacturing of bricks has been investigated experimentally. X-ray diffraction (XRD) studies were carried out to confirm the brick formation and the effect of HEP waste. Ceramic bricks were fabricated with HEP waste additive in proper proportions i.e. 0.5 wt %, 1.0 wt %, 1.5 wt %, 2.0 wt %, 2.5 wt %, 3 wt %, 3.5 wt %, and 4 wt % and then evaluated for water absorption capability and compressive strength. Compressive strength of 6.7 N/mm2, and Water absorption of 22 % have been observed from modified fired bricks impregnated with HEM waste additive. Scanning electron microscopy (SEM) studies were carried out to analyze the effect of HEP waste additive on pore formation and distribution in the bricks. Further, the heat resulting from decomposition of propellants can cause a decrease in the energy required of baking process. The process of manufacturing of bricks with HEP waste additive is first of its kind till date

Prospective Randomized Trial Comparing Endoscopic Sphincterotomy Followed by Surgery with Surgery Alone in Good Risk Patients with Choledocholithiasis

Background: Role of endoscopic sphincterotomy (ES) in high risk patients with choledocholithiasis is established but its role in good risk patients is unclear

Detecting Determinacy in Prolog Programs: 22nd International Conference, ICLP 2006, Seattle, WA, USA, August 17-20, 2006. Proceedings

In program development it is useful to know that a call to a Prolog program will not inadvertently leave a choice-point on the stack. Determinacy inference has been proposed for solving this problem yet the analysis was found to be wanting in that it could not infer determinacy conditions for programs that contained cuts or applied certain tests to select a clause. This paper shows how to remedy these serious deficiencies. It also addresses the problem of identifying those predicates which can be rewritten in a more deterministic fashion. To this end, a radically new form of determinacy inference is introduced, which is founded on ideas in ccp, that is capable of reasoning about the way bindings imposed by a rightmost goal can make a leftmost goal deterministic

Concurrent and Reactive Constraint Programming

The Italian Logic Programming community has given several contributions to the theory of Concurrent Constraint Programming. In particular, in the topics of semantics, verification, and timed extensions. In this paper we review the main lines of research and contributions of the community in this fiel

Hepatoblastoma in an Adult with Biliary Obstruction and Associated Portal Venous Thrombosis

We present a case of adult hepatoblastoma. This young female presented with severe acute cholangitis. Preoperative diagnosis was common bile duct (CBD) obstruction with portal vein thrombosis. On exploration she had a tumor mass in the CBD. The unusual features of this case are discussed in this report

Unusual Tumors Causing Extrahepatic Portal Venous Obstruction

Extrahepatic portal vein obstruction has been reported to be associated with tumors of liver, bile ducts and pancreas. We report two cases, one with gastric leiomyosarcoma and another with Non Hodgkin’s lymphoma, complicated by portal vein block and presenting with gastric variceal bleeding. Portal vein block in both cases was due to direct vascular infiltration. Development of portal hypertension posed difficulties in management
