We present a case of 47-year-old healthy man who underwent an uneventful elective laparoscopic cholecystectomy. Despite the postoperative analgesia with non-steroidal anti-inflammatory drugs (NSAIDs), the patient developed diffuse abdominal pain culminating on the second postoperative day when the patient also had rebound tenderness. A diagnostic laparoscopy showed diverticular perforation, whi...

This paper shows that the migration of educated workers abroad can convey a positive signal about the ability of native talents. When there is uncertainty about the distribution of talents in the donor country and/or about the effectiveness of its education system, migrants may reveal information about their talents. This may enhance the reputation of the workforce both in the host country and ...

-Two-dimensional analytical model for optically biased non-self-aligned and self-aligned short channel GaAs MESFETs is developed to show the photo effects on the Id–Vd characteristics. When light radiation having photon energy equal to or greater than the band gap energy of GaAs is allowed to fall, the drain current increases significantly as compared to dark condition due to photoconductive ef...

This paper presents the derivations of the voltage transfer functions of the amplifier A, the feedback network β, and the loop gain T of the common-drain (CD) Colpitts oscillator, using the small-signal model of the CD Colpitts oscillator. The derivation of the characteristic equation of the CD Colpitts oscillator is presented. Using the characteristic equation, the equation for the oscillation...

The 'beneficial brain drain' hypothesis suggests that skilled migration can be good for a sending country because the incentives it creates for obtaining training increase that country's net supply of skilled labour. Necessary conditions for this hypothesis to work are that the possibility of migration significantly affects decisions to take medical training and that migrants are not strongly s...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...

In this essay, we focus on the moral justification of a highly controversial measure to redress medical brain drain: the duty to stay. We argue that the moral justification for this duty lies primarily in the fact that medical students impose high risks on their fellow citizens while receiving their medical training, which in turn gives them a reciprocity-based reason to temporarily prioritize ...

Objective: To compare the survival and post-op complications following primary closure of perforated peptic ulcer by omental patch technique in 4 groups of patients as follows: two-drain group, one-drain subhepatic group, one-drain pelvic group and nodrain group. Methods: This is a prospective case-controlled clinical study performed in the Jawaharlal Nehru Medical College Hospital, Aligarh Mus...

Electrolyte transport through an array of 20 nm wide, 20 microm long SiO(2) nanofluidic transistors is described. At sufficiently low ionic strength, the Debye screening length exceeds the channel width, and ion transport is limited by the negatively charged channel surfaces. At source-drain biases >5 V, the current exhibits a sharp, nonlinear increase, with a 20-50-fold conductance enhancement...
