Background: The perforation of peptic ulcer is a common and serious life threatening surgical emergency. Up-till now no consensus was reached regarding the best practice in management of perforated peptic ulcer. The aim of this study is to evaluate and compare between both management strategies of perforated peptic ulcer;performing simple closure of the perforation with an omental patch then H. pylori eradication and inhibition of acid secretion using long time proton pump inhibitors versus performing definitive repair of perforated peptic ulcer (closure of the perforation with an omental patch, truncal vagotomy and gastrojejunostomy to discover a proper management strategy of perforated peptic ulcer. Patients and Methods: In the current study we included 30 patients which were divided into 2 groups: group 1 included 15 patients where we managed them by simple closure of the perforation with an omental patch then H. pylori eradication and inhibition of acid secretion using long time proton pump inhibitors and group 2 included 15 patients where we performed closure of the perforation with an omental patch, truncal vagotomy and gastrojejunostomy. Results: We found that younger patient underwent vagotomy and gastro-jejunostomy technique (p Conclusions: Peptic ulcer perforation could be safely managed by primary closure and covering by omentum in addition to medical treatment of H. pylori infection and inhibition of acid secretion especially in old patients with comorbid condition who presented late or with shock.

In this article we will present an attempt to measure the Stark broadening parameter of the Zn I-line at 636.23 nm utilizing the optical emission spectroscopy (OES) technique, taking into consideration the possibility of existence of self absorption. This method is standing on comparison of the Lorentzian FWHM and spectral line intensity of the unknown Stark broadening parameter line (Zn I-636.23 nm—in our case) to a well known Stark parameter line (e.g. Zn I-lines at 472.2, 481 and 468 nm) at a reference electron density of 2.7 × 1017 cm-3 and temperature of 1 eV. We have utilized the emission spectral data acquired from well diagnosed plasma produced by the interaction of Nd: YAG laser at wavelength of 1064 nm with ZnO nanomaterial target in open air. The results indicates that the Stark broadening of the Zn I-line at 636.23 nm is centered at 5.06 ± 0.03 ? with a 25% uncertainty at the given reference plasma parameters. The knowledge of the Stark broadening parameter of the 636.23 nm line may be important in the diagnostics of the laser plasma experiments especially in the absence of the Hα-line.

The construction and operation of atmospheric nonthermal plasma jet, ANPJ, are presented in this work as well as the experimental investigations of its electrical parameters, the configuration of plasma jet column and its temperature. The device is energized by a low-cost Neon power supply of (10 kV, 30 mA, and 20 kHz) and the discharge takes place by using N2 gas with different flow rates from 3 to 25 L/min and input voltage of 6 kV. Diagnostic techniques such as voltage divider, Lissajous figure, image processing and thermometer are used. The electrical characteristics of discharge at different flow rates of N2 gas such as discharge voltage, current, mean power, power efficiency, and mean energy have been studied. The experimental results show that the maximum plasma jet length of 14 mm is detected at flow rate of 12 L/min. The results of plasma jet (heavy particles) temperature along the jet length show that jet plasma has approximately a room temperature at the jet column end. The results of zero flow rate effect on the ANPJ operation show damage in the Teflon insulator and a corrosion in the Aluminum electrodes.

This study was conducted to investigate the effect of different doses injection of human chorionic gonadotropin(HCG)hormone on fecundity and serum sex hormones(FSH,LH,estrogen(E2),progesterone(P4),testosterone(T))of African catfish(Clarias gariepinus).African catfish spawners were intermuscularly injected with different doses of HCG(500,1500,3000,6000 IU/kg female),and group is not injected as a control;males were injected at half the female *** results showed that,fish group injected by 6000 IU HCG/kg female had the highest gonadsomatic index,absolute fecundity and relative fecundity,while,the lowest value of absolute fecundity and relative fecundity were recorded with 500 IU HCG/kg *** group injected with the highest amount of HCG(6000 IU/kg female)recorded the lowest value from egg diameter,while the highest egg diameter was observed in 500 IU HCG/kg *** females,the group injected with 6000 IU HCG/kg female reflected the lowest level of FSH and the highest level of LH and the highest level of P4 compared to other *** of T recorded the highest level with 1500 IU HCG/kg *** control group reflected the highest level of FSH and E2,while the control group reflected the lowest level of T and P4 *** males,serum FSH,LH,P4 and E2 in male groups injected with HCG were relatively higher than those recorded in the control *** highest level of T was recorded in treatment injected with the highest dose of HCG and decreased in other treatments until recorded the lowest level of T in the control *** was observed,HCG hormone has successfully and accelerate induced spawning in African catfish(Clarias gariepinus)and increased in reproductive performance with the increase in HCG dosage and as compared to group not injected.
