This poster presents the efficacy of using AE sensor for touch detection during probing

The Effect of Gypsum Plaster on The Dry Rate of Emulsion

This study was carried out to access the effect of gypsum plaster on the dry rate of emulsion paint. Gypsum plaster sourced from paint manufactures was added in presence of other raw materials to archive a better formulation. The pH the present product (8.4) falls within standard value of paints .The viscosity of the archived was 10 poise compared to that of standard products (8 poise). The dry time however recorded was 70 minutes compared to that of standard product which is usually 90 -110 minutes. These results underscore the need to further explore the use of gypsum plaster in the manufacture of paints considering its positive effects on the properties of paint especially in the reduction of the dry rate. These results underscore the need to further explore the use of gypsum plaster in the manufacture of paints considering its positive effects on the properties of paint especially in the reduction of the dry rate.

Effect of Liquidity on Performance of Deposit Money Banks

The study examines the effect of liquidity management on the performance of DMBs in Nigeria. The objective of the study is to determine the extent of relationship that exists between liquidity mechanism and DMBs performance in Nigeria from 2000 to 2015. The study employs Augmented Dickey Fuller Unit Root Test, OLS regression and Granger Causality. The result of the study revealed that liquidity mechanism is not significantly related to DMBs performance in the short run and long run. The granger result proves that liquidity mechanism hinder DMBs performance within the period under review in the study. Hence, the study recommends that DMBs should be given leverage of plugging back funds into investment to booster profitability while maintaining a level of liquidity ratio.

MICROFINANCING, POVERTY ALLEVIATION AND NIGERIA’S ECONOMIC GROWTH: THE NEXUS

This study investigated the nexus between microfinancing, poverty alleviation and Nigeria’s economic growth from the period of 1992 to 2018. Specifically, it seeks to probe the actual effect of microfinance bank loans on economic growth and employment creation in Nigeria. Augmented Dickey-Fuller (ADF) test, ARDL bounds cointegration test, and the short-run diagnostics and stability for ARDL Model were employed in the analysis. The research findings admitted that, microfinance banks’ operations do not significantly contribution to poverty alleviation in Nigeria. Also, it established that microfinance banks’ loan advances do not significantly affect growth of GDP in Nigeria. Again, microfinance banks’ loans advances have significantly negative contribute to employment opportunities in Nigeria. The implication of the first finding is that, may be attributed to difficulties enshrined in operating environment which make the realization of their objectives cumbersome. Regarding the second findings, the implication indicates that when loans elongated by the microfinance banks to that of business sector and it is not protracted, this will not procreate a corresponding elevate in the economic growth of Nigeria. Also, another implication is that the businesses were not generating enough profit to cover sufficiently the running cost and profit. Therefore, the borrowers will remain in the cycles of borrowing and repaying for years and years. Finally, the significant effect of microfinance banks’ loan advances on creation of employment opportunities on the third finding, the implication is that by granting credit, Microfinance banks enable their clients expand their productivity. This expansion will exact the existing manpower. Additional hands will naturally be engaged to cope with the new level of production. Based on the research findings of this study, for effective loan and advances, microfinance institutions should channel very high proportion of their credits to the productive and real sectors of the economy for valuable impact of their operations on Nigeria’s economic growth. However, Microfinance Banks (MFBs) should therefore, be front-liners of ethical and professional conduct by ensuring that fluffy loans are given to plausible and desirable entrepreneurs. Furthermore, there is should be deliberate policy by the government encouraging the operation of microfinance banks in rural areas and occasionally in semi-urban areas. This will increase savings mobilization of the banks, thereby creating more employment opportunities. JEL: N10; O10; O12; O40  Article visualizations

Th17 cells in human disease

Our understanding of the role of T cells in human disease is undergoing revision as a result of the discovery of T-helper 17 (Th17) cells, a unique CD4 + T-cell subset characterized by production of interleukin-17 (IL-17). IL-17 is a highly inflammatory cytokine with robust effects on stromal cells in many tissues. Recent data in humans and mice suggest that Th17 cells play an important role in the pathogenesis of a diverse group of immune-mediated diseases, including psoriasis, rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, and asthma. Initial reports also propose a role for Th17 cells in tumorigenesis and transplant rejection. Important differences, as well as many similarities, are emerging when the biology of Th17 cells in the mouse is compared with corresponding phenomena in humans. As our understanding of human Th17 biology grows, the mechanisms underlying many diseases are becoming more apparent, resulting in a new appreciation for both previously known and more recently discovered cytokines, chemokines, and feedback mechanisms. Given the strong association between excessive Th17 activity and human disease, new therapeutic approaches targeting Th17 cells are highly promising, but the potential safety of such treatments may be limited by the role of these cells in normal host defenses against infection.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/72455/1/j.1600-065X.2008.00628.x.pd

Microorganism Associated with Cassava Fermentation for Abacha Product Sold in Owerri, Imo State

The microorganism associated with cassava fermentation for producing Abacha was investigated using four different Farms in Owerri (Obinze, Umugwuma, Urata and Orji) as sample collection areas. Four of the cassava tubers that harvested, were washed, cooked and soaked with water after cutting to produce Abacha, which was then fermented using standard microbiological methods. The wastewater was subsequently sampled. All the samples A, B, C, and D showed significant bacteria growth after application of NA, MRS, PDA. In the study, six bacteria and fungi isolates were identified: Escherichia coli, Staphylococcus aureus, Lactobacillus spp, Candida spp., Aspergillus spp. and Bacillus spp. Results showed that the total heterotrophic bacteria count of the sample varies within 8.0×1010 to 2.5×1012 and total fungi count (TFC) ranges from 6.6×109 to 9.6×109. The study also showed that Lactobacillus spp. and Escherichia coli had the highest prevalence occurrence of 75.00% (P < 0.05), while Staphylococcus aureus, Saccharomyces spp., Bacillus spp. and Candida spp. had a percentage occurrence of 50.00%, respectively. There is, therefore, urgent need for public enlightenment on public health implications, need for proper hygiene, as well as need for strategies for preventing and controlling the microorganisms which do not play a role in the fermentation of cassava for Abacha production

G6PD Activity in Malaria Infected Children in Owerri

This paper is a study of G6PD activity in malaria-infected children in Owerri. Blood samples were collected from fifty-one (51) children hospitalized in the Federal Medical Center (FMC) and analyzed using standard Medical Laboratory methods. Results revealed that out of the 51 children examined (26 males and 25 females), 39, representing 76.47% of the total malaria infected children numbers, were G6PD deficient, while 12, representing 23.53%, had normal G6PD. Two different plasmodium species and their percentage occurrences were observed. These were: Plasmodium falciparum (78.43%) and Plasmodium malariae (21.57%). The work indicated that male children were more (P < 0.05) deficient than females, with percentage levels of 61.53% and 38.47%, respectively. In addition, children between the ages of 49-60 months was observed to be more (P < 0.05) G6PD deficient (with percentage of 25.64%), while those between 0-12 months were least G6PD deficient (with percentage of 8.3% (P < 0.05)). As being afflicted with malaria carries a high risk of Glucose-6-phosphate dehydrogenase (G6PD) deficiency in children, there is, therefore, urgent need for public enlightenment on public health implications, need for proper hygiene, as well as a need for strategies for preventing and controlling mosquito population
