Research ArticleOpen accessIn the abstractFundamental Properties of the Galois CorrespondenceAyinde S. Olukayode, Oyekan E. AbiodunProblem Statement: Let K is the splitting field of a polynomial f(x) over a field F and αn be the roots of f in K. Let G be embedded as a subgroup of the symmetric group ς. We determined the Galois group G, and the subgroup. Approach: computed some auxiliary polynomials that had roots in K, where the permutation of … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlantlet Production through Development of Competent Multiple Meristem Cultures from Male Inflorescence of Banana, Musa acuminta cv. 'Pisang Mas' (AA)S. Wirakarnain, A. B.M.S. Hossain, S. ChandranA protocol was developed for the establishment of competent multiple meristem cultures of banana, Musa acuminta cv. 'Pisang Mas' (AA) derived from male inflorescence. The white floral meristem appeared after 21 days in medium supplemented with 10 µM of N6-benzylaminopurine (BA) and 1 µM Indole -3-Acetic Acid (IAA). White floral meristem were optimized in medium supplemented with 100 µM (BA) … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparisons of Phytotoxicity of Barley Parts Extracts in Three Growth Stages on Annual RyegrassKolahi Maryam, Kolahi MinaProblem statement: The importance of allelopathy in nature and in agroecosystem has attracted researcher's attention with the main goal of using the phenomenon in biological control of weeds. currently, active involvement of scientists from different disciplines made allelopathy a multidisciplinary subject, and transformed the research from basic to applied, enabling use of allelopathy in agriculture and forestry.

Research ArticleOpen accessIn the abstractStudy of the Allelopathic Potential of Extracts of Azadirachta Indica (Neem)Zoheir Y. Ashrafi, Aptin Rahnavard, Sedigheh Sadeghi et al.The allelopathic potential of extracts of Azadirachta indica L., which is one of the most dominant weeds in tropical regions of South-west Asia, was investigated under laboratory conditions. The n-hexane-soluble, acetone-soluble and water-soluble fractions obtained from the acetone extract of A. indica shoots inhibited the germination and the growth of roots and shoots of six test plant species. The inhibitory … …OnLine Journal of Biological Sciences, Vol. 8, Issue 3 · 30 Sep 2008 · 7,844 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Saving Mechanism in Clustered Ad-Hoc NetworksArwa Zabian, Ahmed IbrahimIn wireless Ad-Hoc networks, multihop transmission breaks the single hop path from a mobile node to another, into two or more hops, in a manner that the distances between transmitter and receiver are smaller than that in the direct transmission, which reduces the transmission power significantly. We have proposed the use of graph search algorithms to increase the power remaining … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 7,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Ionizing Radiation on Antioxidant Enzymes in Three Species of TrigonellaMuna M. Al-Rumaih, May M. Al-RumaihThe response of three species of Trigonella, namely, Trigonella stellata, Trigonella hamosa and Trigonella anguina to gamma irradiation stress was investigated with respect to antioxidant enzyme induction. When dry seeds were subjected to gamma rays (0, 40, 60, 80, 100 Krad) from a cobalt source 60Co at a dose rate of 233.5 rad/ min, a dose dependent increase in the … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 8,414 accessesView PDFCite
