BACKGROUND The nonsurgical medical approach with use of fibrinolytic agent is an alternative modality in management of chronic empyemas. With the introduction of purer forms of streptokinase, there has been renewed interest generated in the use of intrapleural thrombolytics with documented successful drainage of difficult to drain chronic empyemas. To evaluate the utility of streptokinase in th...

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...

The nuclear envelope, composed of two lipid bilayers and numerous accessory proteins, has evolved to house the genetic material of all eukaryotic cells. In so doing, the nuclear envelope provides a physical barrier between chromosomes and the cytoplasm. Once believed to be highly stable, recent studies demonstrate that the nuclear envelope is prone to rupture. These rupture events expose chromo...

We use the superposition method to model electrostatic characteristics of a high-k stacked gate-all-around heterojunction tunneling field-effect transistor (TFET). The is formed from Ge/Si material in source/channel, respectively. modeling accomplished by considering space-charge regions at source–channel and drain–channel junctions channel region. surface potential region obtained applying pri...

The goal of this paper is to introduce the approximated convex envelope of a function and to estimate how it differs from its convex envelope. Such a problem arises in various physical situations where the function considered is some energy that has to be minimized.This study is a first step toward understanding how to approximate the quasi-convex envelope of a function. The importance of this ...

The effects of surface states on the gate offset regions of GaAs power MESFETs are analyzed using a two-dimensional device simulator with a Shockley-Read-Hall statistics model for the surface states. Assuming electron trap type surface states (ET) and hole trap type surface states (HT) +, it is found that the trap properties cause a large difference in DC performance and pulse operation of the ...
