Param eter estimation in geoelectromagnetics aims to obtain the most im ­ portant param eters of a well-defi ned conductivity model of the Earth. These param eter s are features of typi cal geo log ica l struc tures, such as depth and size of con duct ive or resistive targets, angle of dik e incl inat ion and its length, and con duct ivity of anoma lous bodies. We dev elop thi s approach throug...

sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

Objective: To determine the frequency of various anatomical variations of the cystic duct observed during open cholecystectomy in our set up. Methodology: This study was conducted at department of surgery, Khyber Medical University (KMU), Institute of Medical Sciences (KIMS), Kohat, and a private surgical centre at Kohat, Pakistan. Adult patients of both genders, who underwent open cholecystect...

introduction: this study was done to determine the site of obstruction in lacrimal drainage system in asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. methods:dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99mtc) in 34 patients suffering from unilateral or bil...

According to a previously published report, R- and S-flurbiprofen glucuronides were excreted in the bile after iv administration of the pure enantiomers, but only R-flurbiprofen seemed to undergo enterophepatic cycling. To study the possible stereospecificity in the enterohepatic cycling of flurbiprofen (FL), we investigated the pharmacokinetics of R- and S-FL in control and bile-duct cannulate...

High magnesium concentration inhibits the effect of arginine vasopressin (AVP) on smooth muscle contraction and platelet aggregation and also influences hepatocyte AVP receptor binding. The aim of this study was to determine the role of magnesium concentration [Mg2+] in AVP-stimulated water transport in the kidney collecting duct. The effect of low and high peritubular [Mg2+] on the AVP-stimula...

There is evidence that atrial natriuretic factor (ANF) has an action in the inner medullary collecting duct. In addition, the prehypertensive Dahl salt-sensitive (S) rat has an intrinsic tendency toward less natriuresis than the Dahl salt-resistant (R) rat has when challenged with ANF. To test the hypothesis that renal papillary collecting tubule cells from prehypertensive S rats might be genet...

Mirizzi's syndrome is a rare complication of gallstone disease, that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflammation and resultant bile duct stricture. Most cases are not identified preoperatively. Variations of the cystic duct and its point of union with the common hepatic duct are surgically important. Here, we present an unusual case of type I Mirizzi's...
