Hepatitis B virus (HBV) infection is a global public health problem. It is estimated that there are 240 million HBV carriers in the world, of whom roughly 600,000 die annually from HBV-related liver disease. A total of 150 individuals were included in this study, 130 individuals of them had hepatitis B infection (patients group); HBs-Ag was detected in their sera by enzyme linked immunosorbent assay (ELISA) technique and was confirmed by real time PCR analysis to detect the viral genetic material, the others were control. Most of HBV patients in this study were located within 20-40 years group with a percentage of 47.7% and within the 40-60 years group with a percentage of 38.5%. Acute infection was confirmed by detection of anti-HBc IgM

So, the secret communications through public and private channels are the major goal of researchers. Information hiding is one of methods to obtain a security communication medium and protecting the data during transmission.
This research offers in a new method using two levels to hide, the first level is hiding by embedding and addition but the second level is hiding by injection. The first level embeds a secret message in one bit in the LSB in the FFT and the addition of one kashida. Subtraction of two random images (STRI) is RNG to find positions for hiding within the text.

In this work the Aluminum plasma in Air produced by Nd: YAG pulsed laser, (λ = 1064 nm, τ = 6 ns) has been studied with a repletion rate of 10 Hz. The laser interaction in Al target (99.99%) under air atmosphere generates plasma, which is produced at room temperature; with variation in the energy laser from 600-900 mJ. The electron temperature and the electron density have been determined by optical emission spectroscopy and by assuming a local thermodynamic equilibrium (LTE) of the emitting species. Finally the electron temperature was calculated by the Boltzmann plot from the relative intensities of spectral lines and electron density was calculated by the Stark-broadening of emission line.

tributaries of Smaquli stream during rainfall storm events, which can be used to
establish relationship between suspended sediment concentration and discharge. The
Smaquli catchment is divided into two sub-catchments namely Sarwchawa and
Krosh with areas of 80.64 and 34.82 km2 respectively. Jali dam is built at watershed
outlet. Rainfall, stream discharge, and suspended sediment concentration are
monitored during ten rainfall storms in the water years (2012-2013) and (2013-

In present study, an attempt has been made to investigate the effect of Chlorpyrifos insecticide on carp Cyprinus carpio L. through acute toxicity bioassay. The LC50 were estimated as 1897, 1266, 985 and 792 μg/L during 24 , 48, 72 and 96 hr. respectively by using the concentrations 500 , 1000, 1500 , 2000, 2500 and 3000 μg/L indicating high sensitivity of fish to chlorpyrifos. The behavioral response observed in the fish were erratic swimming, loss of reflex, hyperactivities, decrease in appetite secretion of mucus, increase movement of operculum and hyperventilation . These effects increased with increasing concentration of the chlorpyrifos and duration of exposure.
The current study a accounts for the climate of the Diyala River Basin in Iraq where the climate is assessed depending on the most wellknown climatic classification. According to these classifications, it has been discovered that the area is located under Three climatic zones. The first zone is the semi humid or moderate, which covers the northern parts of the area. The second zone is the semi –dry climate which spreads over the middle part of the region. The third one, it extends over the southern parts and it is described as being dry .some maps were drawn to show the depth of rain fall for two successive periods. These maps indicate increase in the area of lands affected by the dry climate on account of the lands that used to lie

The research aims to apply the novel forward osmosis (FO) process to recover pure water
from contaminated water. Phenol was used as organic substance in the feed solution, while sodium
chloride salt was used as draw solution. Membranes used in the FO process is the cellulose
triacetate (CTA) and polyamide (thin film composite (TFC)) membrane. Reverse osmosis process

process the active layer of the membrane faces the feed solution and the porous support layer faces
the draw solution and this will show the effect of dilutive internal concentration polarization and
concentrative external concentration polarization.

This paper describes the problem of online autonomous mobile robot path planning, which is consisted of finding optimal paths or trajectories for an autonomous mobile robot from a starting point to a destination across a flat map of a terrain, represented by a 2-D workspace. An enhanced algorithm for solving the problem of path planning using Bacterial Foraging Optimization algorithm is presented. This nature-inspired metaheuristic algorithm, which imitates the foraging behavior of E-coli bacteria, was used to find the optimal path from a starting point to a target point. The proposed algorithm was demonstrated by simulations in both static and dynamic different environments. A comparative study was evaluated between the developed algori
