Abstract Cercospora beticola, the causative agent of cercospora leaf spot (CLS) disease, is a serious problem that remarkably impact the yield of sugar beet worldwide. Our aim was to assess the antifungal effect of a natural and more safe extracts of Leaves, flowers and stem bark of Cassia nodosa and salicylic acid (SA) individually or […]
Adsorption of Cr(lll), Pb(ll) and Cd(ll) ions from aqueous solution by Monkey bread (Piliostigma thonningii) seed pod
Abstract The potential of piliostigma thonningii seed pod (a plant waste) as an adsorbent in the removal of Cd(II), Cr(III) and Pb(II) ions from aqueous solution was investigated in this study. The influences of initial metal ion concentration, pH and temperature on the adsorption process were investigated in a batch study. Maximum percentages of each […]
Degradation of Ascorbic Acid during Baking
Abstract Ascorbic acid is added during production of the bread as an industrial oxidizing agent in order to maintain rheological property of bread during baking. In order to determine the effect of temperature on the ascorbic acid content in the dough during fermentation at 25 ºC, 35 ºC and 38ºC and baking temperature in which […]
Lattice energies for metal halides from average orbital electronegativities
Abstract In the present work, an empirical equation is derived, in order to allow the calculation of lattice energies for inorganic monohalides based on the cation radius and the halide average orbital electronegativity: UPOT = (-2.739 r+ + 650.676) Ẋ + (3.796 r+ – 370.851), where r+ = cátion radius (pm) and Ẋ is the […]
A preliminary infrared study of the cellulose of some world stamps
Abstract The infrared spectrum of seven heavily damaged stamps was measured to analyze the cellulose, fillers and sizing elements composing them. In five of them kaolinite was detected as a filler. In one of them Prussian blue was detected as a component of a greenish-blue paper. An attempt to classify them employing a decision tree […]
A Theoretical Study of the Relationships between Electronic Structure and 5-HT1A and 5-HT2A Receptor Binding Affinity of a group of ligands containing an isonicotinic nucleus
Abstract A formal quantum-chemical analysis of the relationships between the electronic structure of two series of isonicotinamide derivatives and their 5-HT1A and 5-HT1B receptor binding affinities was carried out. The electronic structure was calculated at the B3LYP/6-31G(d,p) after full geometry optimization. Statistically significant relationships were obtained for the four cases. The analysis of the results […]
Hypoglycemic Effect of Polyherbal Formulation in Alloxan Induced Diabetic Rats
Abstract Diabetes is a leading cause of morbidity and mortality in the world. There is currently an active search for antidiabetic drugs with greater effectiveness with fewer and less adverse side effects. Therefore, in present study the hypoglycemic potential of polyherbal formulation was investigated in alloxan induced diabetic rats. A list of medicinal plants with […]
Enhanced adsorption capability of Congo red dye onto novel Polypyrrole/ZnO/ZnCr2O4 composite
Abstract In this study, the polypyrrole/ZnO/ZnCr2O4composite as an efficient adsorbent was synthesized by two steps. At first, zinc oxide/zinc chromite (ZnO/ZnCr2O4) composite was synthesized using simple and facile co-precipitation method. Then, ZnO/ZnCr2O4composite was modified by polypyrrole (PPy). The adsorbent was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM) and energy […]
Physico-chemical Studies and Fatty acid Composition of Oil Extracted from Black Weevil Larva from Okitipupa Area in Ondo State, Nigeria (Rhynchophorus phoenicis)
Abstract Studies were conducted on the physicochemical activities and fatty acid compositions of oil from larva of black weevil (Rhynchophorus phoenicis). The percentage yield of the sample was high (69.100±0.20 %), this showed that it is an oily insect. The refractive index and the specific gravity were 1.410±0.01 and 0.9130±0.01 respectively. The results of the […]
Comparative Studies of the Nutritional and Phytochemical Constituents of African oil baen (Pentaclethra macrophylla Benth) and African bean (Anthonotha macrophylla) for Human Consumption
Abstract The powdered crude sample of African Bean (Opagha in Yoruba Language) (Anthonotha macrophylla) and African oil bean (Pentaclethra macrophylla Benth) were subjected to nutritional, phytochemical and mineral analysis using standard experimental procedures to see whether Anthonotha macrophylla, a totally neglected plant seed in west Africa, could serve as close substitute to African oil bean, […]
