Abstract :

Public sector organizations have often been less inclined to fully explore the benefits of knowledge management than the private sector. This paper is aimed to design a Knowledge Management System (KMS) Model with emphasis on Independent National Electoral Commission (INEC).Currently, a lot of public sector information is collected, stored and processed using documents, unrelated Information Systems, and in organization practices internalized by employees. Organizational turnover has also created challenges in the form of knowledge retention and knowledge delivery. Inadequate information access due to information storage challenges is a major problem that hampers proper knowledge service delivery at all levels within the Nigeria public sectors e.g. (INEC).To remain at the forefront, INEC also needs to have a Knowledge Management capability that will store, organize, share, utilize, create and integrate their unmatched knowledge resources, hence the developmentofa Knowledge Management System (KMS) Model is proposed. The features proposed KMS for Nigerian public service organizations will be based on, and aligned with the simplified three-layer model of [5]: 1) Infrastructure Services - storage and communication, 2) Knowledge Services – creating, sharing and reuse, 3)Presentation Services – personalization and visualization, and on the technologies relevant to these services. Structured System Analysis Design Methodology (SSADM) was employed; the results indicated that the proposed model can effectively facilitate the process of storage, sharing and application of KM in the public sectors

Abstract :

This study investigated the influence of commercial banks in financing small and medium scale enterprises in Nigeria to determine the extent to which SMEs access relevance services and credit facilities from Fidelity and First banks as well as their contributions to economic growth in Ibadan metropolis. Descriptive research design was adopted. Purposive sampling technique was used to sample 200 owners of SMEs in Oluyole Local Government Area of Oyo state.  Data collected were analysed using frequency counts, simple percentage score and regression analysis.

The study showed that only 9.37% of the respondents had access to the banking services whereas 37.1% had no access to the banking services being provided by Fidelity and First banks in Ibadan metropolis. From the findings, 2.3% of the respondents strongly agreed that they obtained loans frequently whereas 32.1% strongly disagreed; 8% of them strongly agreed that bank charges on loans are moderate and affordable 38.9% refuted the position. The findings generally revealed that SMEs do not have adequate access to loan facilities from the commercial banks. It is therefore recommended that commercial and microfinance banks should offer financial services like credit facilities at moderate rate of interest with less stringent conditions to SMEs to grow their businesses and generate more employment within the economic hub of the country.

Abstract :

Virtually all over the world teaching and learning has been stopped due to scare and danger brought by Covid-19 pandemic. Consequently, online teaching and learning has taken the centre stage as a way of circumventing the challenge.For a number of years Imenti north sub-county has been posting poor results in Kenya Certificate of Secondary Examination (KCSE) inbiology. Governments all over the world are modernizing their teaching methods to improve the quality of education such as integration of ICT in education, therefore this study sought to establish whether Information and Communication Technology (ICT) resources are used in teaching and learning of biology in secondary schools in Imenti North Sub-County (INSC). Application of ICT resources in school goes beyond the training and equipping of schools with ICTresources, it ought to be a deliberate effort geared into ensuring everything is in place for successful uptake in class. Besidesdeveloping ICTskills, it is important it be integrated in teaching of biology in both offline classes and onlineclasses. With the changing dynamics in classes and rapid evolution of ICT, the need for teachers to acquaint themselves with ICT both in class has become imperative. The study was driven by the ideathat all the countries are in cutthroat competition to be ahead of each other in developing and use of ICT resources in all spheres of life. The study sampled 34 schools that is fiveprivate,three extra county and 26 Sub-County schools selected through stratified random sampling. The study sample composed of, 1305 students, selected through random sampling, 42 teachers selected through random sampling, and 34 head teachers selected through purposeful sampling. Datawas collected through use of interview schedules and questionnaires. Data was then analyzed using descriptive statistics, wherequalitative data was discussed under suitable themes derived from the objectives of the study while quantitative data was analyzed using frequencies and percentages. The study established that schools are rarely using ICT resources in teaching of biology. The study recommend that ministry of education and school managementto take a more proactive role to ensureICTresources are used in the teaching of biology in Imenti North Sub-County.

Abstract :

In December 2019 in Wuhan China, came a virus called Corona-virus, otherwise known as Covid-19. The disease spread all over the world, including Nigeria. It has caused the death of many people in the country as well as damage to the economy. To contain the spread of the virus causing death to people, and damage to the economy, government placed a lot of restrictive measures like lockdown and ban on interstate travels. These measures and similar ones all over the world have caused increase in unemployment as well as other hurts in the economy; and made the demand for the country’s major foreign exchange earner, the oil to fall. This paper supports measures by the government to ameliorate the pains of the pandemic on the country’s economy but also is of the opinion that it pays more attention to the non-oil revenue components of the country’s income generation.

Abstract :

The novel coronavirus (COVID-19) disease outbreak which initially started around mid-December 2019 in Wuhan, China has spread to almost all countries of the world including Nigeria. There are very few studies on some of the basic epidemiological features: exponential growth (EG) and mortality (CFR) ratesof this outbreak in the country while in some cases there are no reliable estimates of these parameters region or state wise. In this study, a purely data-based statistical method was employed to estimate the EG and CFR of the COVID-19outbreak. Daily numbers of laboratory-confirmed COVID-19cases and deaths were collected from April 3 to May 15, 2020 for four regions: Lagos, Kano, Nigeria (except Lagos and Kano) and Nigeria. Simple linear regression model was applied to estimate the CFR while a curve estimation regression model was used for the EG for each region. By 15 May 2020, the estimated exponential growth (EG) rate ranged from 7.0% (95% CI: 6.9–7.8%) in Lagos through 9-0% (95% CI: 8.5–9.3%) in Nigeria and 10% (95% CI: 9.5–10.5%) in Nigeria (except Lagos and Kano) to 12.7%(95% CI: 11.6–13.7%) in kano with a doubling time ranging from 5.5 days in Kano through 6.9 days in Nigeria (except Lagos and Kano) and 7.7 days in Nigeria to 9.9 days in Lagos. The estimated CFR ranged from 1.3% (95% CI: 1.1–1.5%) in Lagos through 3.2% (95% CI: 3.1 – 3.3%) in Nigeria and 4.4% (95% CI: 4.2 – 4.5%) in Nigeria (except Lagos and Kano) to 4.5% (95% CI: 3.9 – 5.0%) in Kano. The study estimates suggest that Lagos is better managed than other regions. Kano has to improve on measures to slow the transmission and reduce mortality rate. Nigeria’s overall situation is still manageable but efforts should be improved upon in curtailing transmission most especially in states where early detection is still low and clinical responses not effective.

Abstract :

Further researches have been on-going in the application of natural organic polymer (NOP) coagulants in contaminant removal from industrial wastewater. The relevance of using Moringaoleifera coagulant (MOC) as NOPfor colour removal from crystal Ponceau 6R dye was investigated in this study. The proximate analysis, structure, surface morphology, and fibre metric study of the precursor were investigated. Response surface methodology (RSM) using face-centred central composite design (FCCD) optimized four process variables including pH, coagulant dosage, dye concentration, and time. The proximate analysis showed a high protein content of 39.34% and fibre content of 1.16%. FTIR analysis showed the presence of O-H, N-H, C=H in the coagulant precursor. The SEM image revealed the image of the polymer rough surfaces,the most occurring pore size 0f 0.41 μm2, different fibre length between 948.44 nm -13.85μm, and a compact net structure. The pH has the highest influence on the colour removal, followed by time as indicated clearly in the main effects plots. Coagulant dosage and dye concentration have less influence on the process. The verification experiments agreed with the predicted values having a standard error value of 1.58%. Overlay contour plot established optimum areas where the predicted response variable is in an acceptable range (≥ 80%) with respect to optimum conditions. The FCCD approach was appropriate for optimizing the process giving higher removal efficiency when compared to the main effect plots. Therefore, protein extract from Moringaoleifera(MO)seed has potentials for application as efficient coagulant while showing significant polymeric characteristics.

Abstract :

This experiment was designed to evaluate the phytochemical, hematologicaland histopathological effects of peanuts when administered to male albino rats. Before the commencement of the experimentation, phytochemical screening of the extract was done.Thirty two albino rats comprising of 8 males and 24 females were used for in vivo experiment. The 8 males were further divided into two groups (A & B). Group A served as control while group B was given 800mg/kgpeanut extract (PE) for 21 days after which 3 female rats selected at random were introduced for each male to breed. The females were left with the males for ten days. After, the males were sacrificed and blood collected for hematology while testes and brain were collected for histopathology. The result obtained showed that peanuts contain among others, flavonoids, steroids, glycosides and carbohydrates. Hematologic profile of male rats treated for 31 days showed that PE treated rats had lower hemoglobin, PCV, RBC but increased WBC all at P 0.05. However differential WBC of the albino rats revealed that PE treated rats had lowered neutrophils, lowereosinophils but increased monocytes and lymphocytes all at P≤ 0.01. The lymphocyte value varied from 42.25±0.559 in treated to 27.00±2.435 in control (n=4).Histopathologic lesions revealed that PE treated rats had densely populated spermatozoa in the seminiferous tubules than control. Conclusion: The research shows that peanut extract contains flavonoids which implies that peanuts have anti-inflammatory, anti-oxidant, anti-bacterial, anti-diabetic, anti-viral and anti-cancer potentials. Peanuts also boost the over-all immunity due to the increased lymphocyte and monocytes observed in the treated rats. It is then suggested that peanut diet be recommended among others for immune compromised persons.

Abstract :

Spider mite is a major constraint in rose flower production. Though flower producers have not quantified the magnitude of the losses incurred, the quantity of the miticides used on their control is enormous. This experiment was designed to investigate the effect of UV spectrum through different poly-films on the occurrence of two spotted red spider mite a common rose flower pest. The study was carried out at Egerton University Horticulture Research and Teaching field. The experiment was split- split plot laid down in a Randomized Complete Block Design (RCBD) with polyfilms forming the main plot treatments. Two rose cultivars were tested for tolerance and calcium foliar feed was applied at four different concentration levels. Rose cultivars and calcium concentrations formed the sub and sub-sub plot treatments respectively. Poly-film samples were scanned through UV- 1800 shimadzu spectrophotometer to assess light transmission properties at different wavelengths. Data collection involved measuring of light transmission through Poly-films, the temperature and relative humidity in the tunnels was also monitored. The data was subjected to analysis of variance at 5% probability level and mean separation was performed using Tukey's Studentized Range (HSD) Test.Poly films modified the tunnel microclimate and this impact on prevalence and population of two spotted red spider mite. Mean temperature values of 41°C, 35.2°C and 32.8 °Cwere recorded under UV-A clear, IR 504 and UV-A 205/N poly films respectively. It was observedthat the number of spider mites increased with increase in temperature.A mean spider mite population of 5 mites/cm2 was recorded under the clear poly-film compared to 3 mites/cm2 under the UV-A 205/N. Changes in greenhouse microclimate influenced the population and prevalence of spider mite. Clear poly film that transmitted high light recorded high temperature and subsequently high number of mites.

Title : Review of Pharmacologic Receptors and Advances

Abstract :

The effects of most drugs result from their interaction with macromolecular components of the same organism. These interactions have the capacity to alter the functions of the pertinent component and thereby initiate a cascade of biochemical and physiological changes that are characteristic of the response to the drug in question. The term receptor therefore, denotes the component of the organism with which the chemical agent is presumed to interact.

This drug-receptor is closely related to the enzyme-substrate complexes or that of antigen and antibody; these interactions have many common features, perhaps the most noteworthy being specificity of the receptor for a given ligand. However, the receptor not only has the ability to recognize a ligand, but can also couple or transduce this binding into a response by causing a conformational change or a biochemical effect

The concept of drugs acting on receptors generally is credited to John Langley (1878) while the word receptor was introduced in 1909 by Paul Ehrlich. A J Clark was the first to quantify drug-induced biological responses (using an equation described firstly by A V Hill in 1909 and then in 1910) and proposed a model to explain drug-mediated receptor activation. So far, nearly all of the quantitative theoretical modelling of receptor function has centred on ligand-gated ion channels and G protein–coupled receptors (GPCRs). However, the richest sources of therapeutically exploitable pharmacologic receptors are proteins that are responsible for transducing extracellular signals into intracellular responses. These receptors may be divided into four families: 1) ligand-gated ion channels, 2) G protein–coupled receptors, 3) enzyme-linked receptors, and 4) intracellular receptors. The type of receptor a ligand will interact with depends on the nature of the ligand. Hydrophobic ligands interact with receptors located on the cell surface (families 1, 2, and 3). In contrast, hydrophobic ligands can enter cells through the lipid bilayers of the cell membrane to interact with receptors found inside cells (family 4). This review also addressed the basic theoretical concepts of full and partial agonism, neutral antagonism, inverse agonism and protean and ligand-selective agonism, and the relevance of these concepts in current rational drug therapy. In this review, the relative shortage of literature in this area of study constitutes a serious knowledge gap waiting to be filled up. Hence, this very review.

Abstract :

A database holds essential assets of an organization. Students’ information, customers’ information, employees’ information and employers’ information of an organization are being kept in the databases. There has been an increase in reported occurrences of data abuses especially by insiders. This research work aimed to investigate for appropriate database auditing techniques applicable on students’ academic records and present logical steps and procedures for implementation using SQL/PLSQL programming in Oracle 11g. Yobe State University (YSU) was used as a case study. Trigger-based auditing, fine-grained auditing, auditing SYS users, and audit trail management are found to be appropriate techniques implemented and evaluated in the proposed developed YSU system. In addition, database security in term of careful creation of database users, privileges allocation to the users, and auditing the activities of the users are also found to be things of significant concern for the reliability and integrity of data. Empirical evaluation showed that application of database auditing on students’ academic records could check proud and internal threats imposed by insiders.
