Contribution to study special kinds of hyperideals in ordered semihyperrings
Publication date: Available online 26 September 2016 Source:Journal of Taibah University for Science Author(s): S. Omidi, B. Davvaz In the present paper, we introduce the notion of k-hyperideals on ordered semihyperrings. Then, we investigate some fundamental properties of k-hyperideals of ordered semihyperrings. Indeed, we define (m, n)-hyperideals and (m, n)-bi-hyperideals in ordered semihyperrings and investigate some of their related properties. Moreover, we introduce and analyze the notion of prime (m, n)-bi-hyperideal of an ordered semihyperring. (Source: Journal of Taibah University for Science)

Publication date: Available online 9 September 2016 Source:Journal of Taibah University for Science Author(s): Esam A. Gomaa, Amr Negm, Mohamed A. Tahoon An Anton Par Model 55 densimeter was used to measure the densities of copper sulphate solutions in H2O and EtOH–H2O at 298.15K, 303.15K, 308.15K, and 313.15K. The acquired information was used to ascertain the apparent molar volumes, limiting partial molar volumes, and transfer partial molar volumes of copper sulphate.

Variations in the cytotoxic glycoalkaloids solamargine and solasonine in different parts of the Solanum incanum plant during its growth and development in Oman
Publication date: November 2016 Source:Journal of Taibah University for Science, Volume 10, Issue 6 Author(s): Sana S. Al Sinani, Elsadig A. Eltayeb, Y.T. Kamal, Masood S. Khan, Sayeed Ahmad In addition to several important traditional medicine applications of Solanum incanum, the plant is a rich source of important cytotoxic glycoalkaloids, such as solamargine and solasonine. Because S. incanum is a potential source of compounds for steroid synthesis, it is worthwhile to study the content of these important glycoalkaloids during plant developmental stages. Therefore, an attempt has been made to quantitatively estim...

Application of a five level central composite design to optimize operating conditions for electricity generation in a microbial fuel cell
Publication date: November 2016 Source:Journal of Taibah University for Science, Volume 10, Issue 6 Author(s): Abdullah N.Z. Alshehria, Khaled M. Ghanem, Saleh M. Al-Garni In this work, a five level central composite design (Box–Wilson design) was employed to optimize the operating conditions for the generation of electricity in a microbial fuel cell. The following three variables were studied: temperature, initial anodic compartment pH and salt bridge component concentrations (agar and KCl). The optimal voltage yield was 17.34% greater than that observed under basal conditions and was achieved with a temperature of...

Genotoxic Studies of Some Plant Oil Extracts on Rhyzopertha dominica (Coleoptera: Bostrichidae)
This study was carried out to clarify the genotoxic effects of different concentrations of plant oils of Eruca sativa (Brassicaceae), Zingiber officinale (Zingiberaceae) and Origanum majorana (Lamiaceae) against the conventional organophosphate insecticide (Chlorpyrifos) as synthetic insecticide against Rhyzopertha dominica Fabricius. The R. dominica population was reared for several generations without exposure to any insecticide. Wheat grains were sterilized at a temperature of 55°C for 6hours in order to eliminate any hidden infestation then treated with serial dilutions of Chlorpyrifos and plant oil extracts and given...
