Authors: Doozakhdarreh, Seyedeh Fatemeh Khademi; Advisor: -; Participants: Khorshidi, Jalal; Morshedloo, Mohammad Reza (2022) - Harvesting time had a significant effect on the essential oil content of plants, so that the essential oil content of plants harvested at 5 am and 5 pm was significantly higher than plants harvested at 12 noon. At all harvest times, shade dried plants had the highest essential oil content, while the lowest content was obtained in microwave-dried plants. Generally, the highest essential oil content (1.12%) was obtained at 5 am harvest and shade dried plants, followed by 5 pm harvest and shade dried (1.08%), and the lowest essential oil content (0.58%) was obtained at 12 noon harvest and microwave-dried plants (Fig. 1). The number, type and total of identified compounds were varied in the essential oils of plants harvested at different times and drying methods (Table 2). The highest n...

Authors: Sharaf, Rasha F.; Advisor: -; Participants: Radwan, Ehab; Salem, Ghada A.; El-yazeed, Mohamed Abou (2022) - Patients whose casts fulfilled the previously mentioned inclusion and exclusion criteria were included in the current study, to analyze dental arch dimensions in children and adolescents with normal occlusion in primary, mixed and permanent dentitions as well as detection of the most common forms of dental arches among Egyptian children.
Results showed that total lower and upper arch lengths showed increase during transition from mixed to permanent dentition. The increase in total lower arch length was from (29.19) in mixed dentition to (30.42) in permanent dentition. Likewise, the maxillary total arch length showed an increase from (32.86) in mixed dentition to (35.74) in permanent dentition

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).
