The inhibition effect of crude juice of green and black olive on cancer cell line (RD) in vitro has been studied by depending on micro titration system . Eleven different concentration starting from (916-960) mg/ml of crude juice respectively ,for three periods of exposure(24-48-72)hours. The resulted showed that the inhibition effect dependent on type of olive fruit juice ,concentration of dose ,time of exposure and the high concentration of both type of olive juice increased the growth of cell line while other concentration caused decrease in different rates ,moreover the black juice was more effective than green and 48 hours' time exposure was the best for inhibition.

    The current study was designed to evaluate the efficiency of broccoli plant in therapy of PCOS that induced for the first time by testosterone andriol (T.A).

   Forty-eight immature female rats (21 days old) were divided into 6 groups (8 rats each) as follows: G1, animals were injected with sesame oil for 39 cascade days (control). G2, animals were injected with 1mg/100g b.w of T.A for 39 cascade days. G3, animals were injected with 1mg/100g b.w of T.A gathered with gavaged broccoli juice (b.j) for 39 cascade days. G4, animals were injected with sesame oil for cascade 39 days at the end of last injection were gavaged with d.w for 30 cascade days. G5, animals were injected with 1 mg/100g b.w of T.A for

The change in the optical band gap and optical activation energy have been investigated for pure Poly (vinyl alcohol)and Poly (vinyl alcohol) doped with Aluminum sulphate to proper films from their optical absorption spectra. The absorption spectra were measured in the wave range from (200-700) nm at temperature range (25-140) 0C. The optical band gap (Eg) for allowed direct transition decrease with increase the concentration of Aluminum sulphate. The optical activation energy for allowed direct transition band gap was evaluated using Urbach- edges method. It was found that ?E increases with increasing the concentration of Al2 (SO4)3 and decreases when temperature increases.

لقد أثارت فكرة القانون الطبيعي اهتمام الفقهاء والفلاسفة في الشرق والغرب ، القدامى منهم والمحدثون وشيدوا نظريات وأقاموا مناقشات حول فكرة القانون الطبيعي والطبيعة والعقل الطبيعي مما جعل هذه الفكرة تبدو إحدى المعطيات الأساسية للفكر الإنساني والتي لا يمكن تجاوزها في إي وقت أو في إي مكان. يبدو إن مفهوم القانون الطبيعي وان كان يعد من اعرق المفاهيم الفلسفية إلا انه يعد واحد من تلك المفاهيم التي وان احتفظت بجوهرها

Transforming the common normal distribution through the generated Kummer Beta model to the Kummer Beta Generalized Normal Distribution (KBGND) had been achieved. Then, estimating the distribution parameters and hazard function using the MLE method, and improving these estimations by employing the genetic algorithm. Simulation is used by assuming a number of models and different sample sizes. The main finding was that the common maximum likelihood (MLE) method is the best in estimating the parameters of the Kummer Beta Generalized Normal Distribution (KBGND) compared to the common maximum likelihood according to Mean Squares Error (MSE) and Mean squares Error Integral (IMSE) criteria in estimating the hazard function. While the pr

Heterogeneous organic compounds play an important role in our daily life as they contribute in many medical and industrial fields and are in continuous development as a result of the preparation of new derivatives with different properties. From this premise, the goal of this work appears, which is preparation of (four, five, six, and seven) membered ring systems derived from furfural, by its reaction with different aromatic aldehydes, and record their antioxidant activity by using free radical scavenging method of DPPH radicals. The new ring systems are synthesized by reacting the prepared Schiff-bases with different ring closure agents (chloroacetyl chloride, mercaptoaceticacid, anthranilic acid, and phthalic anhydride), the prep
