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).

Authors: Adebesin, Ayomide Oluwadarasimi; Advisor: -; Participants: Ayodele, Abigail Oluwakemi; Omotoso, Olabode; Akinnusi, Precious Ayorinde; Olubode, Samuel Olawale (2022) - This study features a computational approach to screen phytochemicals of V. vinifera against β-catenin, a therapeutic target protein that takes part in carcinogenesis through the wnt pathway by employing molecular docking, pharmacokinetics screening, MM/GBSA, and pharmacophore modeling approach.
The molecular docking and binding energy study (Figs. 2 and 3) predicted seven compounds as lead compounds that show a better inhibitory potential when compared with the standard compounds, leucovorin Calcium and Xeloda.

Authors: Hagagg, Laila F.; Advisor: -; Participants: Merwad, Mohamed A.; Shahin, Mohamed M. F.; El-Hady, Eman S. (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.

Authors: Fadeyibi, Adeshina; Advisor: -; Participants: Alabi, Kehinde Peter; Fadeyibi, Mary; Adewara, Adewale Oluwaseun (2022) - Size range characteristics of the banana peel nanoparticles
The result of the size range characterization of the nanoparticles is presented in Fig. 1. This was expressed as a plot of the wavelength versus absorbance in the UV light spectrum. Based on the analysis presented in the Mie theorem (Eq. 1), we obtained the particle size of the banana peel nanoparticles in the range of 3.48–4.92 nm between 495 and 700 nm wavelengths of the spectrum. The nanoparticles showed a negative response to heat absorbance but indicated a positive response to heat transmission at the various wavelengths.

Authors: Ellithy, Marwa Mohamed; Advisor: -; Participants: Aly, Riham Mohamed; Tarek, Heba El-Sayed (2022) - Rosemary nanoparticles composite characterization
Transmission electron microscope (TEM) informed us on the particle shape as well as their size. TEM micrographs of these nanoparticles are shown in Fig. 1. Electron microscopy analysis confirmed the presence of nanoparticles. RE-loaded chitosan nanoparticles were found to be spherical, distinct and regular with a size of 0.5 µm to 200 nm. Their surface is solid and has a dense structure. Chitosan nanoparticles appeared aggregated in the photomicrographs. The RE particles were well coated by chitosan. The particle size of the prepared nanoparticles ranged from 0.5 µm to 200 nm with an average size of 100 nm.

Authors: Zaghloul, Alaa; Advisor: -; Participants: Saber, Mohamed; Gadow, Samir; Awad, Fikry (2020) - Environmental pollution from varied sources is now deemed as one of the most serious problems everywhere. Several pollutants, however, could be perceived by certain biological indicators, each one is used to identify assured single or a category of pollutants. The current review presents the use of biotas, i.e., plants, microorganisms, and animals, to perceive ecosystems pollutants. The most significant biological indicators are presented. The plant indicators described belong to higher plants; the microbial indicators were represented by bacteria, fungi, algae, planktons, lichens, helminthes eggs and enzymes and the animal ones were earthworms, macro-invertebrates, frogs & toads, insects and animal toxins.

While Omicron has shown higher rates of transmission than the other variants, it showed less virulent symptoms with relatively mild disease. The Delta variant, however, has been associated with high virulence causing severe lower respiratory tract symptoms and reduced transmission rate (Kumar et al. 2021). This leaves us wondering; does COVID-19 agree with the trade-off hypothesis?

Authors: Garba, Zaharaddeen Nasiru; Advisor: -; Participants: Ekwumemgbo, Patricia Adamma; Stephen, Godwill (2022) - X-ray diffractometer (XRD)
The detected peaks in the XRD patterns were identified as rhombohedra perovskite structure of BiFeO3 with space group R-3 m and lattice parameters a = b = c = 3.9520 (Å).
Scanning electron microscope (SEM)
The BiFeO3 images, at 100 μm and 20 μm magnifications, exhibit agglomerated particles of various sizes and shapes.
The independent variables and their levels
The low, central, and high levels of the variables are designated as -1, 0, and + 1, respectively. Tests outside the experimental range are denoted as ± α, and they help to predict response functions outside the cubic domain.

Authors: Adegunwa, Abiodun Odunlami; Advisor: -; Participants: Adegunwa, Aderibigbe Kola; Oyatoyinbo, Rokeebat Motunrayo (2022) - Results of recovery analysis
The results of the recovery analysis of the samples are presented in Table 1 and the chromatogram showing the relative abundance and retention of the detected phthalates in Fig. 1a–d. The reliability of the analytical procedures adopted in this study was tested on the basis of its sensitivity, recovery and accuracy. The obtained percentage recovery for the spiked phthalates ranged between 78.50 and 101.21% which fell within the acceptable range of 70–110% of recovery as stated by the assessment of European Union (2008). The recovery results established that the method adopted in this study is dependable and effective and so it is reproducible.

Authors: Salam, Asharaf Abdul; Advisor: -; Participants: Al-Khraif, Rshood M.; Dilip, Thandassery R.; Elsegaey, Ibrahim (2022) - There are a total of 750,998 infected cases, as of April 1, 2022 (2100 per 100,000 persons), with higher infection rates, but almost all recovered (734,820; 2055 per 100,000 persons), while the rest either passed away (9047; 25 per 100,000 persons) or were under treatment (7131; 20 per 100,000 persons). Thus, there is a narrow gap between infected and recovered persons, especially in the first two waves but different in the third wave. However, they are bridged at a faster pace, as shown in Fig. 1. It is the mortality from COVID-19 which has received greater concern in the country due to its ups and downs.
