Authors: Akintan, Michael Olarewaju; Advisor: -; Participants: Akinneye, Joseph Onaolapo (2020) - The result obtained shows that the oil extract of Petiveria alliacea at all concentrations had a significant effect on the adult mosquito for fumigant toxicity with percentage mortality range of 75.00–100% within a 2-h exposure period (P < 0.05) for the leaf extract and 81.67–100% mortality for the root bark extract. The synergistic effect of the leaf and root bark oil was also investigated. The lethal concentration (LC50) of the leaf, root, and synergistic effect of leaf and root oil extract required to kill 50% of the adult Culex quinquefasciatus was 0.45 ml, 0.53 ml, and 0.47 ml, respectively.

Also, the general mean number of captured insects by sex pheromone traps was 432.89 and 633.40 (vegetative stage) and 691.3 and 1865.5 (fruiting stage) adults/trap/week, for treatment and control, respectively. When the first infestation appeared, the non-conventional insecticides were consecutively sprayed once/week for 3 weeks with the following order: Radiant, Coragen, and Emperor (during the vegetative stage).

Authors: Bera, Soumen; Advisor: -; Participants: Das, Sibsankar; Kalindi, Dharmadas (2020) - Strobilanthes kunthiana (Nees) T. Anderson ex Benth locally known as Neelakurinji is an endemic to Western Ghat, India and belongs to the Acanthaceae family. It has a unique flowering pattern to bloom every 12 years. The objective of this review is to highlight the taxonomy, distribution, ecology, biology, pharmacological properties, and conservation status of Strobilanthes kunthiana. The plant S. kunthiana is a rich source of pharmacological constituents and can act as herbal alternatives for various disorders.

Authors: Basha, Amr Mohamad; Advisor: -; Participants: El-Sherbiny, Gamal M.; Mabrouk, Mona I. (2020) - Among 100 P. aeruginosa isolated throughout this period, 59% exhibited reduced susceptibility rates to carbapenems. A total of 20.3% and 57% of CRPA isolates were MDR and XDR, respectively. MIC values of the CRPA revealed that these isolates exhibited high MIC50 and MIC90 to the six selected antibiotics. The findings of the (mCIM) assay displayed identical concordance results with the MβL-CD. Molecular investigation technique assured that 10 (90.9%) and 2 (18.1%) of the 11 XDR selected isolates are positive for blaNDM-1 and blaVIM-1 genes, respectively. Polymyxin B and colistin followed by aztreonam were the most effective antibiotics used for curing infections caused by XDR Pseudomonas aeruginosa.

Authors: Ebikemefa, Clinton Ebimobowei; Advisor: -; Participants: - (2020) - The obtained results from an interactive session with artisanal miners at Bisichi (Kara II) and Kuru-Jentar as well as sampling active and inactive mine pits at the visited mine site prove that a maximum number of 4 bags of cassiterite is mined per day from each lotto pit which is equivalent to ₦660,000 (using the 2018 price of ₦165,000 per processed 50 kg of tin). Samples of cassiterite gotten from the study area show a high percentage of tin (Sn) after X-ray fluorescence (XRF) analysis was conducted on it. Also, the visited mine pit is 3 ft in diameter, the shaft is 30 ft and an adit of 25 ft. Conclusively, the Nigerian Government stands the chance of having financial stability if she seizes the opportunity by ensuring that the mining sector is improved and, also, by forming coope...

Authors: Ibrahim, Muhammad Tukur; Advisor: -; Participants: Tahir, Salisu Muhammad; Umar, Abdullahi Bello; Abdulfatai, Usman (2020) - At 8% glycerol concentration, FP1 has significantly (P > 0.05) the highest percentage motility (73.33%) compared to FPs 2, 3, and 4 (56.68, 50.00, and 23.33% respectively). At 10% glycerol, FP2 had the highest motility (48.33%) and HOST (64.00%). At 15% glycerol, FP4 (fast freezing) had the highest percentage motility (71.67%), viability (76.33%), and HOST (71.67%). At 8%, DMSO concentrations FP4 had the highest significant (P > 0.05) motility, viability, and HOST. Ten percent and 15% DMSO revealed no significant (P > 0.05) difference in most parameters among all the FPS. DMSO performed better than glycerol irrespective of concentrations in all FPS on most parameters evaluated.

Authors: Ismail, Amira Galal; Advisor: -; Participants: Galal, Manar; Nagy, Mohamed Mokhtar (2020) - The continuous rotation motion exhibited significantly lower cyclic fatigue resistance than reciprocating or adaptive motion (p ≤ 0.001) at 37 °C and 20 °C. Cyclic fatigue resistance of NiTi files was affected by the motion used during root canal preparation. Reciprocation motion and adaptive motion resulted in extended fatigue. The operational temperature affects the cyclic fatigue resistance of the twisted file.

Authors: Khalid, Khalid A.; Advisor: -; Participants: El-Gohary, Ahmed E. (2020) - Obtained results showed that Fe (3 g/L), Mg (8 g/L), or Mn (300 mg/L) resulted in the greatest values of growth characters (plant height, fresh and dry weights of aerial parts), EO content (% and mL/100 plants), major constituents of EO (2-hydroxy-1, 8-cineole, β-eudesmol, and camphor), nutrient contents, and their uptakes. Different changes were found in various chemical classes of EO (mono and sesquiterpenes).

Moreover, all conventional insecticide failed these characteristics. The laboratory assessment of the examined insecticides demonstrated that Emperor (Emamectin benzoate) and Coragen (Chlorantraniliprole) were the most superior (LC50 = 0.26 and 0.46 mg L−1, respectively), followed by Radiant (Spinetoram), Vapcomic (Abamectin), and Challenger (Chlorfenapyr) (LC50 = 0.59, 0.60, and 24.07 mg L−1, respectively).

(2020) - This work was carried out through 2017 and 2018 seasons on tow olive cultivars (Kalmata and Manzanillo). Trees were 15 years old, grown in sandy soil, planted at 5 × 5 m apart, and irrigated with saline water through drip irrigation system. This investigation aimed to improve vegetative growth and its mineral contents of the tow olive cultivars. Trees were sprayed with calcium at 0.5% as calcium chloride (21% Ca) and chelated calcium.
