Inverse Transient Analysis (ITA) is a powerful approach for leak detection of pipelines. When the pipe transient flow is analyzed in frequency domain the ITA is called Inverse Frequency Response Analysis (IFRA). To implement an IFRA for leak detection, a transient state is initiated in the pipe by fast closure of the downstream end valve. Then, the pressure time history at the valve location is...

Hepatobiliary scintigraphy is a sensitive method for intra & extera hepatic bile leak diagnosis. Bile lead may be seen after hepatobiliary surgery, trauma, inflammatory disease or malignant neoplasms. Although sonography and CT scanning are useful for diagnosis of peritoneal or perihepatic fluid, they cannot prove bile ascites. Hepatobiliary scintigraphy with Tc-99m-IDA agents is a physio...

background: radiotherapy is one of the most important factors which results in negative effects on wound healing and increases anastomosis leakage. diverting loop ileostomy has been usually performed after colorectal anastomosis in cases of colorectal cancer with a history of neoadjuvant radiotherapy to decrease the chance of leakage. considering the side effects of diverting loop ileostomy, th...

background stress urinary incontinence (sui), the most common type of urinary incontinence (ui), is usually defined as leakage of urine during movement or activity which puts pressure on the bladder, such as coughing, sneezing, running or heavy lifting. it is reported in most countries that 15% to 40% of women struggle with sui and its severe implications for daily life, including social intera...

landfill is the major method of solid waste disposal in developing countries. to protect soil andgroundwater from contamination, anti-seepage systems have to be installed in landfills. however, during theconstruction of anti-seepage system, many factors can result in holes in geomembrane liners. for the purpose of improving construction quality, the construction company needs to find the leaks ...

Deoxygenation-induced red blood cell (RBC) sickling probably activates multiple cation leak pathways. In an attempt to model this, we examined the net passive K efflux ("K leak") from normal and sickle RBCs undergoing elliptical deformation in hypotonic media (200 mOsmol/L). This hypotonic deformation activates two deformation-dependent K leak pathways that are not detectable during the balance...
