Assessment of Housing Finance in Lagos State
(Bells University of Technology, 2019-05-30) ODUNNAIKE, Joseph Seun.; Prof.J.I. Ighalo
Adequate housing provision for the growing population in Lagos state, Nigeria is a major challenge. Addressing this challenge necessitated the involvement of both public and private sectors in the development of housing both public and private sectors in the development of housing both quantitatively. Hence, this study is aimed at examining Lagos state Government and its agency involvement / intervention in housing finance between years 2008-2017 with the view of examining the extent to which the intervention has impacted housing production and delivery in the state. The specific objective of the study includes examining the proportion of housing finance the constitutes Lagos state Government's budget from 2008-2017, examine the contribution of property development company to housing delivery in the state etc. The primary sources were data collected through questionnaires administered on beneficiaries of some randomly selected housing estates in Lagos, property developers and appropriate Lagos state government officials. Questionnaires retrieved were analyzed using appropriate descriptive and inferential statistical methods such as frequency distribution, mean analysis and relative importance index. These were used to improve the validity and ease of communicating results. The study revealed that economic condition and poor allocation of funds to housing is a major affecting utmost performance of Lagos state government in providing adequate housing finance. Also, high interest rate was identified as a problem limiting performance of property developers in housing delivery and they also opined that government can also empower some micro-finance banks\mortgage institutions to grant housing finance loan to citizenry in respective of their income class primarily for development of housing.

Antioxidant is a substance that inhabit the oxidation of other molecules caused by free radical. The inbuilt antioxidant system possessed by living organism are generally not enough to prevent them from oxidative here and for damages and the use of synthetic antioxidants also have some harmful effect. This provide the need to search for more antioxidants from natural sources.Therefore,this study was aimed at evaluating the antioxidant activities of exopolysaccharides produced by lactic acid bacteria isolated from yoghut.Lactic acid bacteria (LAB) were isolated from six different brands of commercially available yoghurt using deMan Rogosa shape (MRS) agar.The LAB isolated were identified based on morphological, biochemical as well as molecular characterizations and were screened for exopolysaccharides (EPS) production. The LAB isolates screened positives were used for EPS production in a liquid medium and the EPS produced were purified and quantified using standard cmethods.Antioxidant activities of the EPS were evaluated by determining the DPPH fess radical scavenging activity, ferric ion reducing power and total phenolic contents. Data obtained were analyzed using Analysis of Variance.Total latic acid bacterial count obtained from the yoghut sample ranged from 0 - 3.9 10 CFU/mL with sample A (Fan Yoghurt) having the highest LAB count (25.49%), L delbrueckii (19.61%), L fermentum (15.69%), L, acidophilus (13.73%), Leuconostoc mesenteroides (11.76%0 Lactococous lactis (7.84%) and Lactobacilus caseil (5.88%).Fifty - one of thr 64 LAB isolated were screen positive for EPS production and only six were able produced susbtantial were quantity of EPS ranging from 127.7 - 208. mg/L..Based on molecular charactrerzation, the four highesr EPS - producing LAB isolated were identified as Lactobcillus plantarum (208.5 mg/L).
Assessment of Genetic Diversity in Winged Bean (psophcarpus tetragonolobus) Using Inter-Simple Sequence Repeat (ISSR) Market
(Bells University of Technology, 2017-10-26) NKANG, Nkoyo Ani; Dr. O. B. Ojuederie
This study determined the genetic diversity in 20 Winged bean accessions. Five Inter
Simple Sequence Repeat (ISSR) primers were screened and used to determine the genetic
relatedness of the accessions of winged bean and also to identify the most polymorphic
ISSR markers for future phylogenetic studies in Winged bean. Phylogenetic relations
were determined by cluster analysis using unweighted pair-group method with arithmetic
averages (UPGMA). Multivariate grouping was carried out using factorial coordinate
analysis (FCoA) and polymorphic information content (PIC) was calculated using
standard procedures. Four out of the five primers had consistent, well banded,
reproducible profiles. The four ISSR primers; UBC 810, UBC 811, UBC 827 and UBC
855 generated a total of 127 amplified bands and all the bands were polymorphic (100%).
The number of polymorphic bands per primer ranged from 14 (UBC 811) to 53(UBC
855). The primers identified between 9 (UBC 811) and 18 (UBC 855) of the 20 winged
bean accessions. ISSR primer UBC 855 had the highest number of polymorphic bands
(53) and identified the highest number of accessions (18). The UPGMA cluster analysis
grouped the 20 accessions of the Winged bean into four major clusters and the
dissimilarity distance ranged from 0.515 to 0.929. The FCoA analysis was comparable to
that obtained using UPGMA cluster analysis. The PIC values ranged from 0.500 (UBC
811) to 0.874 (UBC 855) with an average of 0.718. The percentage polymorphism of
100% indicates high genetic diversity across the genomic loci of the accessions and
revealed the usefulness of ISSR markers in determining the extent of genetic variability
in Psophocarpus tetragonolobus.
Mechanical and Structural Investigation of Zn-MnO2 Coating on Mildsteel
(Scientific Net, 2024-11-01) DEREK Alima O.; FAYOMI Ojo S.I.; ATIBA Joshua O.
Abstract:
Failure in manufacturing industries is a worldwide concern and it occurs most often at elevated temperatures and pressure. Acid, gases, and steam are known to be corrosion and stress-induced propagators resulting in incessant catastrophes. More so, material failure can be due to the substrate material used in the coating while substrate failure can further be classified into the substrate morphology, surface chemistry as well as contamination. Thus, the study developed a multifaceted layer of zinc barrier coating via the electrodeposition technique and observe its response by characterizing the developed coating. The mild steel plate, Zn and MnO2 were procured and characterized according to the ASTM standard. Mild steel of dimension 60×30×2 mm was sectioned and polished using varying sizes of abrasives. The result of the coating thickness showed that Zn-6MnO2 had a weight gain of 0.30g. Zn-12MnO2 was observed to have excellent corrosion performance compared to the as-received and the other formulations of Zn-MnO2 with a corrosion resistance of 2.117 mm/year. The SEM image of Zn-MnO2 showed aggregates of clustered grains, thus, no possible fracture lines were observed on the coating surface. Zn-12MnO2 exhibited a hardness value of 252.72 BHN. Additionally, the EDS of the coatings revealed significant elements that helped in the corrosion performance and hardness properties of the coatings.
Continuous Learning and Employees Peformance in Bells University of Technology, Ota, Ogun State, Nigeria
(Bells University of Technology, 2024-08-06) OLUSUPO, Margaret Odunayo
This study investigates the impact of employee engagement on organizational performance among selected commercial banks in Ota, Ogun State. The objectives of the study were to determine how training and development, work-life balance and employee retention impact organizational performance. Data for the study was sourced primarily with the aid of a structured questionnaire. The study made use of the entire population for the sample study as the population was less than 100 (population < 100). To test the hypotheses, the data was analyzed using descriptive statistics such as percentage, mean, and standard deviation, as well as inferential statistics such as multiple regression analysis. The findings revealed that all variables understudy (raining and development, work-life balance and employee retention) all had a moderately significant impact on organizational performance, showing a predictive value of .95%. The research findings emphasize the multifaceted nature of organizational performance and the necessity for organizations to adopt a holistic approach to talent management; While training and development, work-life balance, and employee retention each play a role in shaping organizational outcomes, their combined influence yields the most significant impact. Thus, organizations must strive to create a conducive work environment that fosters employee growth, well-being, and retention to drive sustained organizational success in the long term. Furthermore, the study recommends that organizations should prioritize the development and implementation of strategies to enhance employee engagement, such as fostering a supportive work environment, providing opportunities for growth and development and promoting a healthy work-life balance.
