Authors: Abdullahi, Mustapha; Advisor: -; Participants: Adeniji, Shola Elijah; Arthur, David Ebuka; Musa, Shuaibu (2020) - At first, the structure of the compounds was accurately drawn and optimized using the Spartan 14 software at DFT level of theory with B3LYP/6-31G** basis set in a vacuum. The diverse chemometric descriptors were computed from the optimized structures using the PaDEL descriptors software, and the division of the dataset into training and test sets was done based on Kennard-Stone’s algorithm. Five (5) models were generated from the training set using genetic function approximation, and model 1 was chosen as the best due to its robust internal and external validation metrics (R2train = 0.8563, R2adjusted = 0.8185, PRESS = 3.5724, average R¯¯¯¯2m (LOO-train) = 0.6751, Q2cv = 0.7534, R2pred= 0.7543, R2test = 0.6993) which passed the model criteria of acceptability. 6-Bromo-N-(2-(4-bromop...

Authors: Osman, Hamida Ahmed; Advisor: -; Participants: Ameen, Hoda Hussein; Mohamed, Moawad; Elkelany, Usama Samy (2020) - Compared to the untreated control, all treatments exhibited variable potential inhibitory activities against root-knot nematode M. javanica and enhanced peanut yield production. The most nematode suppressive treatment was the single treatment of Saccharomyces cerevisiae, followed by T. harzianum either singly or combined with the yeast. Moreover, data indicated that application of the combined treatment of yeast plus T. harzianum gave the best results in improving peanut production, plant growth parameters, and seed nutrient contents.

Authors: Adeniji, Shola Elijah; Advisor: -; Participants: Arthur, David Ebuka; Abdullahi, Mustapha; Adalumo, Olajumoke Bosede (2020) - The established model was swayed with topological descriptors: MATS7s, SM1_DzZ, TDB3v, and RDF70v. More also, interactions between the compounds and the target “DNA gyrase” were evaluated via docking approach utilizing the PyRx and Discovery Studio simulated software. Meanwhile, compound 19 has the most perceptible binding affinity of − 16.5 kcal/mol. Consequently, compound 19 served as a reference structural template and insight to design twelve novel hypothetical agents with more competent activities. Meanwhile, compound 19h was observed with high activity among the designed compounds with more prominent binding affinities of − 21.6 kcal/mol.

Authors: Chikezie, Paul C.; Advisor: -; Participants: Ekeanyanwu, Raphael C.; Chile-Agada, Adaeze B. (2020) - The level of poly-dHbS-M of the control sample was significantly higher (p < 0.05) than those of the samples containing 40, 60, and 80 mg/100 mL ethylacetate extracts of A. occidentale at t < 60 s. The relative cumulative polymerization index (RCPI%) of dHbS-M in the presence of fractionated leaf extract of A. occidentale varied within a wide range of 3.8–59.4%. A. occidentale (petroleum ether and ethylacetate extracts), P. guajava (n-hexane, chloroform, and ethylacetate extracts), and T. catappa (ethylacetate extract) exhibited comparatively high potency to inhibit poly-dHbS-M.

Authors: El-Araby, R.; Advisor: -; Participants: Rezk, A. I.; El-Enin, S. A. Abo; Nofa, O. A.; El-Nasharty, A. B. (2020) - The ethanol has higher extraction efficiency and the ultrasonic probe recovered higher oil % in the blank sample. Seventeen samples of S. bigelovii cultivated under different combined treatments of fertilization and irrigation recorded oil % less than the blank sample. The fatty acids profile cleared that the oil of cultivated samples (17 samples) had power for biodiesel production with high ignition properties and good stability due to the high cetane number and a high percentage of palmitic acid. The nutrition value of the blank sample is higher than that of the other 17 samples. The polyunsaturated fatty acids in the blank sample represent > 63% of the total fatty acids.

(2020) - Results have showed a non-significant decrease in serum VEGF activity in the (CH.BG) (M) group when compared to other groups during 2, 3 weeks, followed by gradual decrease, then increase at 12 weeks of interval period. There was highly significant increase from pre-surgery to 12 weeks in serum BMP-2 levels in the (CH.BG) (M) group when compared to other groups.

Authors: Jimoh, Olatunji Abubakar; Advisor: -; Participants: Akinola, Micheal Olawale (2020) - The result revealed snails fed with UPWP had the least final weight and weight gain which was accompanied by the highest feed intake across the treatments. Average egg laid, hatchability, fertility, embryo mortality, and average juvenile produced by snails on roughage-based diet were significantly the least across the treatments. High gonadosomatic index of snails on leaf meal-based diet accompanied with better reproductive output in laying snails was recorded.

Authors: Idoko, Joy Ejemen; Advisor: -; Participants: Ileke, Kayode David (2020) - The results from the study showed that the effectiveness of the essential oils was dependent on application rates and time of exposure. In the treated cowpea seeds, A. melegueta essential oil was the most effective with 50% lethal concentration (LC50) value of 2.42 ml/kg and 95% lethal concentration (LC95) value of 4.86 ml/kg when compared to the other treatments as indicated by the application rate which caused 50% and 95% mortality of cowpea beetles. A. melegueta essential oil at the concentration of 5 ml/kg achieved 100% mortality of C. maculatus at 48 h of application. Cowpea seeds treated with 5 ml/kg of E. globulus essential oil significantly reduced (P < 0.05) oviposition compared to the other treatments. Cowpea seeds treated with 5 ml/kg of A. muricata essential oil reduced ...

Authors: Elsayed, Shaimaa I. M.; Advisor: -; Participants: Glala, A. A.; Abdalla, Aboelfetoh M.; El-Sayed, Abd El Ghafour A.; Darwish, Mona A. (2020) - The results demonstrated that dill cv. Dukat gave the highest plants (cm), maximum leaf number per plant, pigment content (mg/g), total carbohydrates (%), nitrogen, and phosphorus percentages in the vegetative growth stage. Meanwhile, dill cv. Balady recorded the maximum potassium percentage and low content of nitrate accumulation (mg/kg) in the vegetative growth stage. Both dill cultivars contained antioxidants without significant differences between them. The best fertilization treatments were 100% organic fertilization with biofertilizer and 100% chemical fertilizer for plant height (cm), leaf number per plant, pigment content, antioxidant percentage, total carbohydrate percentage, and N and P percentages of two dill genotypes. On the other hand, 50% organic fertilization with bi...

Authors: Galal, Manar; Advisor: -; Participants: Hamdy, Tamer M. (2020) - No single geometrical design could be beneficial for all stress conditions. To decrease the stress accumulation during bending of rotary files in curved root canals, the rotary NiTi instruments should be designed with rectangle cross-section configuration, low pitch, reduced taper, and with centered cross section. This design improved the flexibility of rotary NiTi instruments. However, to improve the torsional resistance during root canal preparation of narrow canals, the file should be designed with parallelogram cross-sectional configuration, low pitch, increased taper, and eccentric cross-section design.
