3-TIER E-COMP: A NOVEL E-COMMERCE MANAGEMENT PORTAL BASED ON SECURED SDLC APPROACH

In today’s business world, there is an urgent need to develop a new approach for customer to business owner transactionssecurely. This research develops, implements, and discussed a novel 3 – Tier E-Commerce Management portal. This makesonline business very flexible and secured on the part of business owners and customers. Our proposed system seeks toreplace the conventional E-commerce models on the internet today. We argue that process logic manipulation using SecuredSoftware Development Life Cycle (SSDLCM) on Ecommerce platform is a promising scheme for studying andunderstanding script processing on the new web paradigms. In this research, we define security calculus for 3 Tier EComPwith the aim of eradicating SQL injection possibilities as well as exploiting Software as a service in a dynamic Ecommercedomain. Also, we developed a new access hierarchy for E-commerce comprising of Application layer users, designatedadministrator and super administrators in the 3 – Tier EComP. We developed a new encryption scheme based on XAMPMD5 Random Curve Cryptography (XMD5 – RCC) running on Secure Socket Layer (SSL) which protects the user andadministrators on the Ecommerce platform. The result of encryption scheme randomly generates and secures the logindetails dynamically on the server during the authentication and authorization phases. The programming was accomplishedwith PhP, and MySQL Server. The overall methodology as detailed in the body of the work could serve as good template forapplication developers and other researchers.Keywords: E-Commerce, XMD5-RCC, SSL, Platform, SSDLCM, Software, Servic

Helminth Fauna Of Tadarida (Chaeraphon) Nigeriae (Thomas, 1913) (Microchiroptera: Molossidae)

A checklist of helminth parasites isolated from Tadarida (Chaeraphon) nigeriae is presented. Out of 857 bats examined 658 (76.78%) were infected by helminth parasites. Details of the taxa presented show that 2 were trematodes; 2 were cestodes; and 5 were nematodes. Observation on the distribution of the worms within the host shows that they were found mainly in the alimentary canal and peritoneal cavity. Rictularia was the predominant helminth parasite of these bats in this study with 49.59% of the bats examined found infected with this parasite. Female bats were found with higher infection rates with the helminths than the males. There are similarities in the type of parasites infecting bats collected from Nsukka and those collected from other places. Significant levels of positive associations exist between the parasites. Food habits based on stomach content anayses revealed that in volume and in actual numbers, beetle (Coleoptera) andmoths (Lepidoptera) comprised the major prey items in the diet.

Relationship Between the Standard of Living, Economic Situation, and Security Situation of Nigerians During The Covid-19 Pandemic. A Non-Parametric Analysis Approach

The Covid-19 pandemic has crippled the economic activities of so many nations across the globe since its outbreak in 2019. This study is focused on the resultant effect of the covid-19 pandemic in terms of standard of living, perception of economic and security situation of Nigerians. This study used a non-parametric approach involving Spearman rank correlation and Mann-Whitney U to analyze primary data acquired from NoiPolls’ online administration of questionnaires during the Covid-19. The result obtained from this study depicts that there is a significant relationship between the security situation and perception of the country’s economic situation. The standard of living of Nigerians was studied alongside their perception of the economic situation and we observed that there is a significant relationship between these two. This was also examined based on gender, the Mann-Whitney U test was used to check if there exists any form of difference between males and females based on the security situation, economic perception, and standard of living. The test result showed that there is no significant difference in the standard of living of both males and females but significant differences were observed in the economic perception and security situations. A bar chart was further used to visually assess these differences where it is seen that females feel more secure compared to males and females feel less satisfied with the country’s economic situation compared to the males

Effect of Fermentation on the Anti-Nutritional Factors and

The effect of fermentation on the anti-nutritional factors and mineral composition of melon seed varieties for Ogiri production was studied. Melon seed varieties such as Citrullus vulgaris, Citrulluslanatus, Colocynthiscitrullus, Cucurbita pepo, Cucurmeropisedulis were respectively sorted, washed, boiled wrapped seed were then boiled again for 2 hours, drained, cooled and allowed to ferment naturally for 86 hours (primary fermentation). The primary fermented sees were then pounded and wrapped in little portions with “ofoala” leaf (Icacinatrichantha olive) and kept in wire mesh near a heat source for another 144 hours (secondary fermentation). Samples were drawn from the raw, boiled and fermented melon seed varieties for the quantitative analysis of mineral content and anti-nutritional prepared with the raw and primary fermented samples. Raw seed of Citrulluslanatus had the highest mineral analysis showed a decline in the boiled samples and secondary fermented sample, compared with the raw and mineral composition ranging from potassium, magnesium, cacium, iron and zinc of 1.21, 1.06, 0.89, 0.45 and 0.41mg/100g respectively followed by raw Citrullus Vulgaris with potassium, magenesium, calcium, iron and zinc of 1.18, 1.02, 0.55, 0.44 and 0.38 mg/100g respectively and 1.11, 0.94, 0.81, 0.38 and 0.31 mg/100gof potassium, magenesium, calcium, iron and zinc respectively in the primary fermented product. Statistical analysis of anti-nutrients revealed a significant reduction (p<0.05) in all the processed melon. There was a significant difference in all the processed melon with lowest anti-nutrient content ranging from alkaloid, saponin, HCN, phytate, tannin and flavonoid (0.00, 0.00, 0.00, 0.00, 0.03and 0.09 respectively) and Colocynthiscitrullus had the highest anti-nutrient content in the secondary fermentation.

Pattern and Determinants of Antiretroviral Drug Adherence among Nigerian Pregnant Women

Background. The need for a high level of adherence to antiretroviral drugs has remained a major hurdle to achieving maximal benefit from its use in pregnancy. This study was designed to determine the level of adherence and identify factors that influence adherence during pregnancy. Method. This is a cross-sectional study utilizing a semistructured questionnaire. Bivariate and multiple logistic regression models were used to determine factors independently associated with good drug adherence during pregnancy. Result. 137 (80.6%) of the interviewed 170 women achieved adherence level of ≥95% using 3 day recall. The desire to protect the unborn child was the greatest motivation (51.8%) for good adherence. Fear of being identified as HIV positive (63.6%) was the most common reason for nonadherence. Marital status, disclosure of HIV status, good knowledge of ART, and having a treatment supporter were found to be significantly associated with good adherence at bivariate analysis. However, after controlling for confounders, only HIV status disclosure and having a treatment partner retained their association with good adherence. Conclusion. Disclosure of HIV status and having treatment support are associated with good adherence. Maternal desire to protect the child was the greatest motivator for adherence

Nanostructured Clay (NC) and the Stabilization of Lateritic Soil for Construction Purposes

The use of Nanostructured Clay additive in lateritic soil stabilization and their effect at different percentages on the natural soil was investigated. The preliminary tests on the soil showed it was an A-2-7 soil, according to AASHTO classification. The soil sample was also observed to be silty clayey sand and the general rating as a sub-grade material was ‘GOOD’. The consistency limits result shows that the value of the LL for the natural soil is 47% and 25.15% was recorded for the plastic limit (PL) and finally the PI was 21.85% i.e. highly plastic soil. Further, the effect of the addition of NC in the proportions of 3%, 6%, 9%, 12% and 15% by weight of the stabilized Umuntu Olokoro lateritic soil was investigated. The consistency limits results showed that the addition of variable proportions of NC considerably improved the plasticity of the stabilized soil which gave 13.8%; a medium plastic material at 15% NC addition, compared to the preliminary result of 0% by weight additive which gave 21.85%; a highly plastic material. The strength properties’ test showed significant improvements with the addition of NC; CBR test result recorded 29% at 15% by weight proportion of NC which satisfies the material condition for use as sub-base material and the UCS test results similarly improved consistently and recorded a maximum UCS of 340.18kN/m2 at 15% by weight proportion of NC addition which satisfies “very stiff” material consistency for use as sub-base material. With the foregoing, the addition of various proportions of NC to the stabilized lateritic soil has presented to be a Geotechnical solution to the varied environmental failures on the road pavements. Hence NC satisfies all the material conditions for use as a sub-base material for the stabilization and improvement of the strength characteristics of lateritic soils. Finally, we call on the relevant agencies to use NC as an additive in stabilizing weak lateritic soils for use as either sub-grade or sub-base materials to save both cost and the structural failures on the roads in south eastern Nigeria.

Assessment of the Quality of Borehole Water Sample in Federal Housing Estate and Sites and Services Areas of Owerri, Imo State, Nigeria

Assessment of the quality of borehole water samples from Federal Housing Estate and Sites and Services areas of Owerri, Imo State, Nigeria was conducted to determine the suitability of these borehole water samples. Six samples of borehole water gotten from six different families living in these areas were analyzed for microbial, chemical and physicochemical parametersusing standard analytical method of National Agency for Food and Drug Administration and Control (NAFDAC). The result of microbial analysis revealed that all the water samples (samples D, E, F, G, H, and M) had total coliform count of 64.0cfu/100ml, 5.0cfu/100ml, 41.0cfu/100ml, 16.0cfu/100ml, 124.0cfu/100ml and 0.0cfu/100ml respectively. This showed that sample D, F, G, and H exceeded the standard of 10 coliform counts/100ml. The entire samples resulted at 0 counts for Escherichia coli. Samples D, F, G and M tested negative for pseudomonas test, whereas samples E and H did not. The chemical analysis showed that all the samples did not meet up with the recommended standard of pH (6.5-8.5).However, there was significant difference (p<0.5) between samples D and E. samples F and J were significantly the same, also as samples G and M. Sample M was the least significant while sample D was the most significant at pH 4.6 and 6.4 respectively. The temperatures were all significantly the same and did not exceed standard limit of 370C. The total dissolved solid also did not exceed the limit of 500ppm and the conductivity limit was not exceeded. All the samples did not exceed limits for zinc, copper, lead, magnesium, cadmium and iron which are 3mg/l, 1mg/l, 0.01mg/l, 0.02mg/l, 0.03mg/l and 0.3mg/l  respectively except for calcium, where samples D, E, G and H were beyond standard of 0.4mg/l. All the samples were significantly different for each parameter except for lead of which the entire sample were all the same. The depth of the borehole in relation to the distance of septic tank, distance of neighbor’s septic tank and distance of refuse dump as obtained from these families revealed that sample M had the highest distance and was the least contaminated, whereas sample H had the closest distance and the greatest microbial contamination. The depth of Sample G borehole was according to the regulatory standard of 150 ft., and from the analysis the entire parameters were within standard except for pH.
