Communications today has been done among millions of users using many application devices like internet or satellite communication channels, the services they can transform many varieties of files like text, images, videos, and audio among different places. Therefore the security of data has been of extreme importance in today’s information-based society, including the fields of military, diplomacy, corporation, medicine, and etc…. A form of data hiding is steganography, which is contemporary way for protecting the information by embedding data into digital media for the purpose of copyright, and sending secret messages. In this paper a scheme of steganography system for hiding secret text message in audio file WAV, (Windows Audio Visual) format is proposed, the hiding mechanism was based on using Low-Bit Encoding (LSB) Least Significant Bit substitution techniques. To support the immunity of the hiding system, encryption methods with some other support methods (i.e., hiding and hopping) were added to the proposed hiding system, a pseudo random number generator has been designed and implemented to generate non-uniform integer jumps between successive hiding events. The jumps mechanism of the suggested generator is based on the linear feedback shift register of length 23 with feedback function F(x)=1+X+X23 produce the maximum period 223-1= 8388607.

Smart antennas have numerous important benefits in mobile communication systems. Smart antennas can provide higher system capacities by directing narrow beams toward the users of interest, while nulling other users not of interest. This allows for higher signal-to-interference ratios, lower power levels, and permits greater frequency reuse within the same cell. This, in turn, increases the system capacity and the quality of services. In this paper we analyze the effect of base-station sensitivity obtained by using smart antenna to increase capacity and reduced the mobile transmit power at different loads scenarios.

Libraries can play a major role in the dissemination of knowledge as a huge repository of knowledge. This research shows the description for the content of the electronic library using metadata and Resource Description Framework (RDF) to facilitate access to content at any time based on this description, thus providing a more meaningful search. In this paper provides an integration of computer science techniques with electronic libraries, and determination of semantic features of this content by proposing a new scheme representative in the Resource Description Framework (RDF) and modification of the basic elements in RDF Dublin core.

In this paper, the state of non newtonian fluid of second order flow injected uniformly into the vertical channel with porous wall through one side of the channel. The equations which are used to describe the flow are the motion and the energy equations. It found that these equations are controlled by many dimensionless numbers such as Reynolds number (Re), Peclet number (Pe), Hartman number (M) and the material of fluid (α,β). The homotopy analysis method (HAM) is used to obtain the analytic solution for the velocity and heat transfer. The effect of each dimensionless parameters upon the velocity and temperature distribution is analyzed and shown graphically by using MATLAB package.

Several concentration of local probiotic with premix(mixed of vitamins & minerals)as a dietary supplementation in fish rations T1 (0.5%)T2(1% )T3(1.5%)T3( 2%) besides T5 (as control).Results showed that there were a significant differences between treatments (P˂0.05) T1 and T2 appeared the best performance in biological parameters (weight gain, weight rate)food conversion efficiency, blood characteristics. Results also appeared that (all probiotic and premix treatments) affected positively in fish productive performance compared with control treatment in all of parameters. As a conclusion, using of premix with probiotics improved the fish rations besides the rising of fish productive performance which due to decreasing the costs of project with gaining high fish weights.

In this research extraction and Identification of chemical compounds (active substances) in the plant Alhagi and plant pine. Where the chemical extraction of these compounds using alcoholic solvents, then the diagnosis of these aggregates are effective in these plants using the equipment of chemical and spectral analysis, diagnostic and classical chemical methods.

This study was conducted on green tea Camellia sinensis to determine the inhibition activity of plant aqueous extract against bacteria Staphylococcus spp.; The extract showed good inhibitory activity against S. aureus and S. epidermidis with 21.00 and 23.00 mm at 20 mg/mL, respectively with no significant differences with that of 10 mg/mL. The results compared to that of Ceftriaxone , Amoxicillin and Gentamicin antibiotics using agar well diffusion technique. The inhibition zone S.aureus was 10.00, 4.00, 7.00 mm for antibiotics Ceftriaxone , Amoxicillin and Gentamicin while S.epidermidis was 13.00, 5.00, 9.00 mm. The MIC results showed for the antibiotics ceftriaxone , Amoxicillin and Gentamicin which 8.00, 16.00, 5.00 and 6.00, 10.00, 3.00 mg/mL for S.aureus , S.epidermidis respectively.

The research contained preparation of Marjoram plant extract in aqueous / alcoholic 50 / 50 (extraction temperature at 65 ˚C). and examination of plant extract by infrared spectroscopy FT-IR and ultra violate spectroscopy UV. The technique of gas chromatography - mass spectrometry GC-Mass for the identification of some of the ingredients of extraction by soxilet, Such as Nitrosomethane ,Hydroxypropanoic acid, di-tert-Butyl dicarbonate, Phthalic acid, Trimethyldecane compounds and flavonoids.

The aim of this study was to detect pyrovidene production and siderophore characterization from local isolates of fluorescent Pseudomonas which were isolated from rhizospheric region of sorghum. The isolates were tested for inorganic phosphate solubilization and biofilm formation. All isolates produced pyrovidene and other siderophores on King B broth comparing with pseudomonas broth, nutrient broth enriched with 10% egg white and succinate broth. Characterization of siderophores indicated the presence of hydroxymate siderophores from all isolates while only two isolates produced catechole siderophore. All isolates showed an ability of solubilized inorganic phosphate with release of 1795 ppm by 2nf isolate as comparing with minimum release 89 ppm by 6nf isolate. Biofilm could be detected on broth when bacterial biofilm adhering to the glass tube, black color formed at top of bacterial growth with Congo red stain on solid medium and on the bottom of liquid medium.

The current research included palynologicalstudy for towentythree taxa of the genus EuphorbiaL. From thefamily Euphorbiaceae. The study included measurement the dimensions of pollen grains and their shapesin polar and equatorial views and measuring the thickness of the pollen wall and sculpturing.The study showed that there are variations in pollen grains characters for the studied taxa.which have an important taxonomic value.

The methods of statistical and scientific have become common use in solving administrative problems to reach the correct decisions in order to find optimal solutions to administrative problems facing the administration at different levels. The process of controlling inventories aimed at identifying the needs of the State Company For Leather Industries (SCLI) materials inventory and supplies the quality and quantity so as to ensure the achievement of these goals optimally This includes research pointing to some of the statistical tools and how to use them to control the level of the Safety Stock of the material processed from the local markets and so to avoid the two cases, the first non-accumulation of material in the stores as a capital investor and second to avoid a shortage situation that may affect the company depending on the actual demand that is variable and Lead time is fixed.

Show us that the Contracting arose originally in the arms of the civil law, but due to the development of economic and social conditions have added to the Contracting Terms unusual in civil contract and a guarantee to the public interest as the subject of entrepreneurship is one of the projects or buildings of government departments, for this and put in the contract terms of insurance, fines and pull contract from one party is the government in addition to insurance, execution and style tenders. The ratios of the methods of the tenders were not government regulations no. (1) For the year 2014 its share in most of them and encourage and even legitimize the financial and administrative corruption as always prefer to choose the contractor, according to the will of the circle. The insurance and fines conclusion they are few and is a deterrent to the contractor and the best of them for the public benefit is a penalty clause which up to 70% of the contract amount. Also suggested activating the law of graft No. 15 for the year 1958 for all financial and administrative corruption titled where did you get this? Add file to give each contractor to the Commission on Security and integrity to follow the spoilers from the beginning and to the end. Pena also unnecessary to activate the law of government debt collection No. 56 of 1956 which has become disabled and give the Director-General of the Department of the validity of the port each year in order to get government debt, the most convenient and easiest way instead of the courts, which is time consuming. Pena also unnecessary to refer the dispute to arbitration courts first second and not left to the desire of the contractor willing to preferred arbitration courts first and later because the disruption of the public facility to the state.
