In this work, two different laser dye solutions were used to host highly-pure silicon nitride nanoparticles as scattering centers to fabricate random gain media. The laser dye was dissolved in three different solvents (ethanol, methanol and acetone) and the final results were obtained for methanol only. The silicon nitride nanoparticles were synthesized by dc reactive magnetron sputtering technique with average particle size of 35 nm. The random gain medium was made as a solid rod with high spectral efficiency and low production cost. Optical emission with narrow linewidth was detected at 532-534 nm as 9 mg of silicon nitride nanoparticles were added to the 10 -5 M dye solution. The FWHM of 0.3 and 3.52 nm was determined for Rhodamine B and

The results shows existence of metals such as copper, iron, Cadmium, lead and zinc in most of examined samples , the highest concentration are up to (2.26, 40.82, 282.5, 31.02, 19.26, 4.34) Part per million) ppm) in pasta hot (Zer brand), Indomie with chicken, granule (Zer brand), brand (Zer brand), and rice (mahmood brand) respectively, with presence nickel in spaghetti( Zer brand), granule, Zer brand with concentration reached to 4.34 ppm and 1.06 ppm respectively.
The results of cereals group and its products show that two kinds of fungi, Aspergillus spp. and Penicillin spp. were found in rice (Mahmood brand) with numbers got to 1.5×103 Colony Forming Unit/ gram (c.f.u./g),while Bacillus cereus and Staphylococcus aureus were isola

Language is the realistic and sensitive basis for any communication between two or more parties. It is an important workshop that prepares meanings and coding them according to a linguistic structure governed by agreed rules that speak to and coexist with everyone.

Whereas the forms of communication are: personal, mediator and mass, none of them can move away from language in their dealings and communication patterns. Since each has its own characteristics and skills, it must be launched in its fields through verbal and non-verbal symbols and wears the elements of influential language as intended.

It makes the recipient face two things: whether he fails to understand those symbols hence its purpose fail, or he meditates s

        Dünyanın muhtelif yerlerinde yaşayan, farklı din, kültür ve etnik gruba mensup olan insanlar arasında nazar inancının mevcut olduğu bilinmektedir. Nazar inancı İslam dinine inananlar arasında olduğu gibi farklı semavi ve gayri semavi dinlere inanan insanlar arasında da mevcut olduğu çeşitli pratik ve uygulamalardan tespit edilebilir. İnsanlar, nazara gelmemek için çeşitli yollara başvurmaktadırlar. Kötü nazarlı insanlara karşı her zaman bir korku, rahatsızlık ve çekingenliğin var olduğu söylenebilir. Dolayısıyla birçok insan, nazara ve başına kötü bir şeyin gelmemesi için söz konusu nazarı kötü

Abstract

The twentieth century French novel had undergo a significant change that took the form of a radical move from the traditional son who follows his father to one who no way prevalent in the classical French novel. The new son in the 2Oth century novel finds himself emotionally attached which both became a new trend and approach in novel writing.

Marcel Proust's novel which can be considered a source of inspiration for most of 2Oth century novelists is a good example of the mother supremacy which is crystal clear from the first page through its parts and chapters till the last page. In fact, Proust had written a completely different novel from the Balzacian conventions. Unlike the latter's novels, Pro

The present study aimed to identify the therapeutic evaluation of chitosan extracted from the fungus cushroom and pure chitosan on glucose and lipid profile in the blood of 35 male rabbits with hyperlipidemia induced experimentally by cholesterol. The tests included estimation of glucose levels, total cholesterol, triglycerides, high-density lipoproteins, low-density lipoproteins, and very low-density lipoproteins. hyperlipidemia was induced in the male rabbits used in the study which was administered orally with cholesterol 150mg/kg body weight for a week. rabbits were divided into seven groups: control, cholesterol, pure chitosan, mushroom chitosan, cholesterol and pure chitosan, cholesterol and mushroom chitosan and cholestero
