Precursors due earthquake have been studied in the history; whence, scientists were striving for finding an effective way to forecast earthquakes. When looking at the physics scientists formulated scenario of earthquakes ...

يطبق موضوع الارتباط القانوني عندما تكون هناك مجموعتين كبيرتين، ولكل مجموعة عدد من المتغيرات يراد البحث فيها عن الارتباطات المتداخلة بين تلك المتغيرات، لذا يتوجب الحصول على نظام متناسق في كل مجموعة من المتغيرات، حيث إن ...

In this research two different source were used with different material in order to investigate the attenuation of x-ray and Gamma- ray as function of the absorber thickness and to compare the effect of this source in ...

This study was carried out on the leaves of Adansonia digitata. In this work, powdered sample of Adansonia digitata leaves were sequentially extracted using water, methanol, ethanol, acetone, ethyl acetate, and ...

We give a decomposition theorem for the Sobolev space of first order on the disc. Using this result, some characterizations for algebraic properties of Toeplitz or small Hankel operators with symbols in 𝐿∞,1 are given. ...

This dissertation is slightly an introductory review to understand quantum computing and methods of quantum error correction, in this dissertationwe focused on interpreting the theoretical part of quantum noise and errors ...

Palm pollen were macerated with aqueous ethanol at room temperature . Fractionation of the ethyl acetate extract of palm pollen over silica gel column followed by a Sephadex column gave two compounds(I and II) classified ...

In this work the effect of changing the anode of polymer solar cell on their performance was experimentally investigated .The cells were fabricated from ITO which act as a cathode beside MEH PPV ,Ecrchrom Black T and ...

The aim of this study was to determine of nitrite ions (NO-2) in some locally produced, processed meats samples. Twenty three samples were obtained from the local markets in Khartoum state. The cured meat samples include ...

On this study we design the simple device that contents two electrodes ( working electrode) and (reference electrode). The reference electrode is a silver-sliver chloride, and the working electrode is zinc oxide nanoparticles ...
