Authors: Asare, Ebenezer Aquisman; Advisor: -; Participants: Assim, Zaini Bin; Wahi, Rafeah Binti; Tahir, Rajuna Bin; Droepenu, Eric Kwabena (2021) - The results showed that all the analyzed water quality parameters were within the allowable threshold levels. The results obtained by the application of fuzzy comprehensive evaluation and grey clustering evaluation methods proved that the coastal and the estuaries waters were clean with exception of coastal location CZ9 and the estuary of Salak river which showed slight pollution. Based on the Malaysian Marine Water Quality Index, it was observed that all the locations were in the classification group of moderate (i.e. 50–79%). This suggests that the estuaries of selected rivers can be used for natural resource conservation, while the coastal regions are good for fish farming.

Authors: El Refay, Amira Sayed; Advisor: -; Participants: Hashem, Shaimaa A.; Mostafa, Hend H.; Kamel, Iman H.; Sherif, Lobna S. (2021) - The overall mean Sleep Disturbance Scale for Children score (SDSC) in participated groups was 44.6 ± 11.72. Of 765 participants 502 (65.6%) showed the symptoms suggestive of sleep disorder. Disorders of initiating and maintaining sleep were the most common among participants as 168 (33.4%) of them were suffering from it while 79 (15.7%) children were suffering from excessive somnolence. Linear stepwise regression revealed that anxiety score, understanding safety measures, and following strict quarantine measures significantly predicted SDSC (p = 0.001, 0.009, 0.046). Significant positive correlations were found between SDSC and extra screen usage, understanding safety and quarantine measures, anxiety signs, and change in child lifestyle with (p = 0.029, 0.010, 0.001 and 0.001) seque...

Authors: Okunlade, Adelekan Oluseyi; Advisor: -; Participants: Esan, Oluwaseun Olanrewaju; Ogunleye, Akinlabi Oladele (2021) - Pet birds are housed and reared exclusively for ornamental use. These include psittaciformes (parrots, parakeets, budgerigars, love birds) and passeriformes (e.g. canaries, finches, sparrows, also called songbirds). E. coli is a Gram negative bacterium. In birds, it is called Avian Pathogenic E. coli and is a causative agent of avian colibacillosis. Antimicrobial resistance is the process through which bacteria evade the activity of antibiotics. According to WHO (World Health Organization), antibiotic resistance is the result of indiscriminate use of these drugs which are used both in Veterinary and human medicine.

Authors: Sarkar, Priyadharshini; Advisor: -; Participants: Samanta, Aveek; Maity, Tilak Raj; Datta, Siraj (2021) - The effect of the selected drugs on radicle length, colchicine induces polyploidy and in vitro callus growth has been studied (concentration used: 5-Fluorouracil—0.01, 0.1, 1 and 10 mM; Cyclophosphamide—1, 10, 20 and 30 mM). The biochemical studies on superoxide dismutase, catalase and lipid peroxidase activity also studied. Radicle length, polyploidy percentage and callus growth decrease in both the drugs in a dose-dependent manner. The SOD, catalase and LP activity decrease with the increase in drug concentration except for low dose (for 5FU—0.01 mM and 1 mM for CP). Induced polyploidy (Control B) than water germinated seedling (Control A) shows higher enzyme activity but a decrease in the increased dose of drugs.

Authors: Sharma, Chetna; Advisor: -; Participants: Sahota, Param Pal; Kaur, Sarabjit (2021) - The physicochemical parameters observed in the fermented Kanji beverage were pH 3.47, total soluble solids 3°B, lactic acid 0.99%, total sugars 36.32 mg/mL, total reducing sugars 27.16 mg/mL, flavonoids 38.14 mg/mL, phenols 40.8 mg/mL, antioxidant activity 79.96% and ascorbic acid 110 mg/100 mL. The microbiological analysis revealed an exponential increase in lactic acid bacterial count from 3.96 to 8.33 log CFU/mL. Out of 11 bacterial strains isolated from Kanji, the bacterial strain with high growth potential was genotypically characterized as Pediococcus acidilactici with accession number MK028218.

Authors: Jasper, Enebi Estella; Advisor: -; Participants: Onwuka, Jude Chinedu; Bidam, Yakubu Manasseh (2021) - The results of this study revealed that the concentration of the activating agent had the most significant effect on the yield of the active carbon produced as well as on its adsorption capacity for methylene blue. The optimum preparation process conditions were found to be: concentration of activating agent 5M, activation time 30 min and activating agent, NaOH which resulted in an active carbon yield of 21.25%, and an adsorption capacity of 9.33509 mg MB per gram of active carbon. SEM and FTIR showed evidence of successful activation.

Authors: Wijewardhana, T. Dilmi. U.; Advisor: -; Participants: Ratnayake, Amila Sandaruwan (2021) - The milled samples were subsequently heated for two hours continuously at temperatures of 800 °C, 900 °C, 1000 °C, 1100 °C, and 1200 °C, respectively. Initial and annealed samples were analysed using X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, and X-ray fluorescence (XRF) analyses. XRD pattern of the initial sample was characterized by less percentage of rutile (TiO2) peaks and low crystallinity. However, the number of rutile peaks and crystallinity were increased with respective milling hours and annealed temperature. Besides, XRD analysis indicates a higher number of sharp and intense rutile and elemental iron peaks in the samples annealed above 1000 °C. FTIR analysis of raw ilmenite indicates mainly stretching vibrations of Fe–O. However, vibrational ...

Authors: Ologundudu, Foluso; Advisor: -; Participants: - (2021) - Results showed that minimum proline content (12.07 mg/g) and maximum proline determination (16.05 mg/g) were observed in Ife bpc at 5 and at 15 dS/m under NaCl and Na2SO4 treatments. The LP content significantly increased in Ife brown at 15 dS/m under NaCl treatment and at 10 dS/m (9.49 mg/g) under Na2SO4 salinity. Minimum GSH content (120 µm/g) and maximum glutathione accumulation (138.97 µm/g) were observed in Ife bpc in the stressed cowpea seedlings (5 and 10 dS/m) under NaCl treatment with respect to the control. Also, SOD activities in the leaves of Ife brown increase with increase in salinity stress in both NaCl and Na2SO4 treatments.

Authors: Ichu, Bright Chigozie; Advisor: -; Participants: Opara, Alexander Iheanyichukwu; Ejike, Emmanuel Nnamdi; Nkwoada, Amarachi Udoka; Ibe, Francis Chizoruo; Dioha, Emmanuel Chuka (2021) - Results of the study showed that Zn concentration levels were not significant at all the sampling points, while the concentrations of Pb particulate matter which ranged from 0.11 to 0.91 µg/m3 exceeded the international revised EPA Pb standard of 0.15 µg/m3 but within the approved Federal Ministry of Environment (FMEnv) Nigeria, 24 h long duration of 1 µg/m3, and National Ambient Air Quality Standard (NAAQS) 1 h duration (1 µg/m3). The enrichment factor (EF) showed that Pb had a dominant crustal source, while Zn was determined to be of minor to moderate crust enrichment. The multivariate analysis carried out using principal component analysis (PCA) based on varimax rotation and Hierarchical Cluster Analysis (HCA) plotted in biplot and dendrogram diagrams revealed the levels of depen...
