INTRODUCTION Although cystic duct variation is quite common, duplication of cystic duct is an extreme rare variant. We report a case of double cystic duct with literature review. A 33-year old female presented with right upper quadrant pain of three day duration, associated with nausea and poor appetite. The patient reported previous three attacks of right upper quadrant pain within the last tw...

Pattern formation in Rayleigh-Bénard convection in a large-aspect-ratio cylinder with a radial ramp in the plate separation is studied analytically and numerically by performing numerical simulations of the Boussinesq equations. A horizontal mean flow and a vertical large scale counterflow are quantified and used to understand the pattern wave number. Our results suggest that the mean flow, gen...

BACKGROUND Gastric cancer is notably one of the leading causes of cancer-related death in the world. In Malaysia, these patients present in the advanced stage, thus narrowing the treatment options and making the surgery nearly impossible for successful curative resection. Failure to identify high-risk patients and delay in diagnostic endoscope procedure contributed to the delay in diagnosis. Th...

the purpose of the research was to examine the relationship between educational administrators' brain quadrant dominance and the level of their performance effectiveness. by using stratified-random sampling method, 103 managers and 412 teachers were selected as the study sample; they were recruited from high schools in mashhad in 2008-2009 academic year. herrmann brain dominance instrument, wit...

We report a case of intramural gallbladder hematoma mimicking gallbladder neoplasm in a 33-year-old male; bleeding was confined to the gallbladder wall without rupture into the lumen. The patient presented with sudden onset of right upper quadrant pain, with no history of abdominal trauma. The abdomen was soft, with mild tenderness over the right upper quadrant, and a positive Murphy's sign. Ab...

Consider two insurance companies (or two branches of the same company) that divide between them both claims and premia in some specified proportions. We model the occurrence of claims according to a renewal process. One ruin problem considered is that of the corresponding two-dimensional risk process first leaving the positive quadrant; another is that of entering the negative quadrant. When th...

A 76-year-old woman complained of abdominal pain in the right upper quadrant and fever that had been developing over the previous 10 days. On examination, she presented pain in the right upper quadrant with positive Murphy’s sign. Computed tomography showed the presence of acute cholecystitis and, as a casual finding, the presence of cholelithiasis with air in its interior (Fig. 1). The presenc...

A blind adaptive multiuser detector (MUD) based on the Linearly Constrained Constant Modulus Algorithm is presented. The dependence of the performance (in terms of BER and SINR) on step size and amplitude estimation is quantitatively investigated through computer simulation.
