Background: Helicobacter pylori (H. pylori) infection is associated with gastritis and may induce atrophic gastritis have specific circulating immunoglobulin G (IgG) antibodies.
Aim of the study: To confirm the correlation between Helicobacter pylori infection and gastric atrophy.
Patient and Method: A study was conducted in the period between December 2005 and March 2006 on 25 patients with atrophic gastritis attending Gastroenterology and Hepatology Teaching Hospital in Baghdad, and 25 healthy volunteers who agreed to donate blood. Sera were tested for H. pylori IgG Ab by ELISA test.
Results and Conclusions: detection of H. pylori IgG Ab were applied to each individual, showed that (92 %) of patients with atrophic gastritis had positive H. pylori IgG Ab were as only 4 (16 %) of normal healthy individuals had positive H. pylori IgG Ab.
In this paper, we used maximum likelihood method and the Bayesian method to estimate the shape parameter (θ), and reliability function (R(t)) of the Kumaraswamy distribution with two parameters l , θ (under assuming the exponential distribution, Chi-squared distribution and Erlang-2 type distribution as prior distributions), in addition to that we used method of moments for estimating the parameters of the prior distributions.

A theoretical model is developed to determine time evolution of temperature at the surface of an opaque target placed in air for cases characterized by the formation of laser supported absorption waves (LSAW) plasmas. The model takes into account the power temporal variation throughout an incident laser pulse, (i.e. pulse shape, or simply: pulse profile).
Three proposed profiles are employed and results are compared with the square pulse approximation of a constant power.
