    Opis:
    We study the bound state solutions of the Klein-Gordon equation with Woods-Saxon plus attractive inversely quadratic potential using the parametric Nikiforov-Uvarov Method. We obtained the bound state energy eigenvalues and the corresponding normalized eigen functions expressed in terms of hypergeometric functions. Two special cases of this potential are discussed.

    Opis:
    The solutions of the Schrӧdinger equation with Manning-Rosen plus a class of Yukawa potential (MRCYP) have been presented using the Pekeris-like approximation and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions are obtained in terms of Jacobi polynomials. Also, inversely quadratic Yukawa, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potential and their Eigen values obtained. The Numerical results are computed for some values of n at l = 0 with α = 0.01, 0.1, 2 and 5 using python 3.6 programming, and these results could be applied to molecules moving under the influence of MRYP potential as negative energy eigenvalues obtained indicate a bound state system.

    Opis:
    Plant extracts have been used widely with and without chemical modification for various infectious diseases cause by bacterial activities. All the methanolic plant extract of Sclerocarya birrea showed anti-microbial activities against most of the test organism with some showing a better antibacterial and antifungal activities than others. The leave from Kem has the minimum bactericidal/fungicidal concentration of 50 mg/ml for E. coli, 100 mg/ml for C. albican and S. aureus but A. niger has 200 mg/ml whereas on the other hand from Yola S. aureus, C. albican, A. niger and E. coli has 100 mg/ml. The stem has the minimum bactericidal and fungicidal concentration of 50 mg/ml for E. coli, S. aureus and 100 mg/ml for C. albican and A. niger and on the other hand from Yola has 100 mg/ml for E. coli, S. aureus and 200 mg/ml for C. albican and A. niger. The roots from Kem has 50 mg/ml for E. coli and S. aureus and 100 mg/ml for C. albican and A. niger and from Yola has 100 mg/ml for E. coli, S. aureus, C. albican and A. niger has 200 mg/ml. This shows that the stem and roots of Sterculia Setigera is more sensitive to the tested organism and is bactericidal at low concentration. The leaves extract in both locations has the MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The stem extract from Kem has the MIC of 25 mg/ml for bacteria and 50 mg/ml for fungi and on the other hand from Yola, the extract has MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The root showed different minimum inhibitory concentration from Kem, the extract has 25 mg/ml for bacteria and 50 mg/ml for fungi. On the other hand, the extract from Yola has 50 mg/ml for bacteria and 100 mg/ml for fungi. Finally, the limit of detection for both plants collected from two different geographical areas for inhibitory effect has been measured successfully.

    Opis:
    Oil was extracted from the dehulled seeds of Lagneraria siceraria (bottle gourd) and analysed for physico-chemical properties, as well a fatty acid composition. Standard procedures were employed in all analysis. The seed oil was liquid at room temperature with percentage yield (23.65%). The oil was characterized in terms of specific gravity (0.918 g/cm3), refractive index (1.34), viscosity (26.46 X 103 poise), melting point (11-14.5 °C), moisture content (0.18%), saponification value (203.36 mg KOH/g), unsaponifiable matter (7.13%), iodine value (46.1 g/100g), peroxide value (7.5 meq/kg), free fatty acid value (18.42%), acid value (60.02 mg KOH/g) and ester value (143.34 mg KOH/g). It was also classified as non- drying (iodine value ˂115 g/100 g). The peroxide value indicates that the oil is less prone to rancidity with iodine value less than 30meq/kg. The high saponification value qualifies it for use in the manufacture of soaps and shampoos. Four classes of fatty acid were identified in the oil: palmitic acid (C16:1) (13.5 ± 0.21), stearic acid (C18:1) (6.5 ± 0.96), oleic acid (C18:1) (11.6 ± 0.62) and linoleic acid (C18:2) (68.4 ± 0.13). Linoleic acid was the most abundant fatty acid in the oil. The fatty acid content of the oil reveals that L. Siceraria seed oil could be a rich source of oil for domestic and industrial purposes if exploited.
