A tabletop prototype of a new kind of nuclear reactor was demonstrated recently at the University of Bologna. This note addresses conceptual difficulties associated with the reported features of the device.

Background: Common bile duct stones are found in 10-15% of patients having gall stone disease and the incidence increases with the age, both in India and in western countries and the majority of common bile duct stones are secondary to gall bladder stones, their incidence is more in Northern India. Objective: To study the incidence of common bile duct stone in patients having gall stone disease...

Sound transmission through ducts of constant cross section with a uniform inviscid mean flow and a constant acoustic lining (impedance wall) is classically described by a modal expansion, where the modes are eigenfunctions of the corresponding Laplace eigenvalue problem along a duct cross section. A natural extension for ducts with cross section and wall impedance that are varying slowly (compa...

Using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. Use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. In this work two-dimensional incompressible laminar flow of a nanofluid e...

S21 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 would be altered depending on the cytological diagnosis achieved. EUS FNA is a very good option with minimal risk to give a tissue diagnosis before planning surgery. DOI: 10.4103/2303-9027.212328

congenital nasolacrimal duct obstruction (cnldo) is a common disease in children. the classic treatment of cnldo is probing that was done around one year old. however, controversy exists regarding the outcome of probing in children older than one year. this study aimed to find the cure rate of initial probing for cnldo and identify factors producing the failure rate in old age. in this retrospe...

The formation of acetate by Acetobacterium woodii was studied systematically in batch-operated stirred-tank reactors at different hydrogen and carbon dioxide partial pressures in the gas phase. 48 parallel stirred-tank reactors on a millilitre-scale as well as stirred-tank reactors on a litre-scale were applied for the detailed reaction engineering analysis of hydrogenotrophic acetate formation...

OBJECTIVE To compare pancreatic duct cell function in smokers (current and past) and never smokers by measurement of secretin-stimulated peak bicarbonate concentration ([HCO3-]) in endoscopic collected pancreatic fluid (PF). METHODS This retrospective study was cross-sectional in design, recording demographic information (age, gender, etc.), smoking status (former, current, never), alcohol in...

CONTEXT Intraductal papillary mucinous neoplasms (IPMNs) are being recognized with increased frequency and are the most common indication of pancreatic surgery at specialized centers. Many IPMN patients are found to have non-IPMN related pancreatic tumors like pancreatic neuroendocrine tumors (PNTs). OBJECTIVE To study the prevalence of PNTs among patients with IPMN. METHODS Patients who un...

Sugar binding proteins and binders of intermediate sugar metabolites derived from microbes are increasingly being used as reagents in new and expanding areas of biotechnology. The fixation of carbon dioxide at emission source has recently emerged as a technology with potentially significant implications for environmental biotechnology. Carbon dioxide is fixed onto a five carbon sugar D-ribulose...
