The aim of this study was to know the inhibition activity of squeezed grape waste extract on Bacillus stearpthermophilus by using three different tempretures degree 40, 60 and 80c, in order to reduce the time exposure of food for preservation. This study include two branchs: First: isolation and identification of Bacillus stearothermophilus from soil, 5 sample were collected from the soil of the college agriculture/Baghdad university. Samples were cultured on nutrient agar, microscopic and culturing tests were conducted and many biochemical tests were done. The isolates were cultivated at 55 c and 65 c for differentiate it from Bacillus coagulans which is can't grow at 65 co. The choosed isolate was identified as B. stearothermophilus which is bacilli, spore forming, g+ve ,motile and with 0.71-3 µm diameter. Second studying the inhibition activity of squeezed grape waste extract against isolated bacteria (in vitro) by using different temp mentioned above at differenttimes(0, 10, 30, 40 and 50) min with 500 ppm conc. Of the extract. The number of cells at 40 c for control were 4 x 102 cfu after 50 min, the number was decreased to 2.88 x 102 cfu with the extract. This decreasion was increased as the time progress for three temp. The best decreasing was 4 x 10 cfu at 60 c with extract and 3 x 102 cfu for control after 50 min. At 80 co it was higher a little bit at 60 c, it was 5 x 101 cfu with grape waste extract and 2.1 x 102 cfu for control.
In this paper, a method for hiding cipher text in an image file is introduced . The
proposed method is to hide the cipher text message in the frequency domain of the image.
This method contained two phases: the first is embedding phase and the second is extraction
phase. In the embedding phase the image is transformed from time domain to frequency
domain using discrete wavelet decomposition technique (Haar). The text message encrypted
using RSA algorithm; then Least Significant Bit (LSB) algorithm used to hide secret message
in high frequency. The proposed method is tested in different images and showed success in
hiding information according to the Peak Signal to Noise Ratio (PSNR) measure of the the
original ima
Thethesis of theresearch is to deal with relations between Russia and Yemen after 2011.That relationwas significant in different fields, historic, economic, strategic and cultural ones. There are mutual interestsbetweenRussia and Yemen, especially with the economic development and growth in Russia as an important partner to Yemen.Their has to an a great deal of progress in different types of relations, where as they were only partner in military relations. The studywasclassifiedintoto three sections: the first section dealt with strategic importance of Yemen to Russia. And second section dealt withthe military factor between Russia and Yemen. While the third section dealt with the economic factor between Russia and Yemen. In addi
