Experimentation And Modeling Of Infective Treatment And Recovery Of HIV Patients (A Case Study Of Kwara State)

The outbreak and spread of diseases have been studied for many years. The ability to make predictions about diseases could enable scientists to evaluate inoculation/vaccination or isolation plans and may have a significant effect on the mortality rate of a particular epidemic. Therefore this research experimentation and modeling of infective treatment and recovery of HIV patients (a case study of kwara state) will studynbspnbsp the rate at which people contact the HIV, investigate how many people a person can infect at a particular point in time. , develop model for male and female with HIV, develop estimating functions for such a model and determine the control measures and sensitivities to change in parameter. Regression analysis, Chi ndash square and SIR model were use to analyse the data. Result of the analysis using regression analysis give the fitted model Y= 12.302 + 0.00009X and Y= 13.077 + 0.00007X for male and Female respectively. The result shows that the fitted model is adequate and the rate at which people contact HIV is increasing. Also chi - square analysis revealed thatnbsp contacts ofnbsp HIV is not depend on gender and that there are differences in respondents health when taking drugs recommended by health workers. Further analysis using SIR model shows that there will likely be epidemic on HIV and that 29% of the male that have HIVnbsp must be treated to avoid epidemicsnbsp 9% of the female that have HIV must be treated to avoid epidemics. And we recommend that Health Planner should administer enough drugsnbspnbsp to HIV patient on regular basis and Health Planner should educate people more on HIV and the preventive measure should be thought

Impact Of Marketing Strategies And Performance Of Banks And Its Ffects On Nigeria Economy

The banking industry has been facing a lot of challenges in recent times in Nigeria. These include competition among them and non banking financial institutions such as insurance Companies. Therefore this research, impact of marketing strategies and performance of banks and its effects on Nigeria economy is aimed tonbsp identify the various types of the marketing mix components employed by thenbsp banks . to examine the effect of the marketing strategies on the performance of the banks. Andnbsp to determine if the marketing strategies employed by the Banks differ significantly from one another. Questionnaire was administered on two population which arenbsp Management andnbsp staff of thenbsp banks and customers of thenbsp banks. 250 questionnaire was administered tonbsp Management andnbsp staff of thenbsp banks,nbsp and also 250 was administered to customers of the bank in Nigeria. Result of the analysis revealed four factors which were distribution network, quality of service, promotion and price with the percentage contribution of each factor being 51.9%, 73.6%, 31.2% and 38.5% respectively. Multiple regression analysis shows that R2 = 0.563 which indicated that the four factor accounted for 56% variability in the performance ofnbsp marketing strategies employed by the banks. The result of the analysis of variance indicated that the mean ratings for thenbsp banks were not significantly different at 0.05level. We thereby conclude that banks should focus its innovative efforts on enlarging the size of the market in which it participates by introducing new products and services, promoting new uses for existing products and seeking out new class of customers

Growth Pattern of Pseudomonas aeruginosa in different wastewater media

Restaurant wastewater are a major cause of environmental pollution with the indiscriminate release of the effluent to the environment resulting in blocking of drainages and eutrophication thereby causing serious threat to aquatic life. The growth pattern of a dietary rich oily wastewater degrading bacteria strain, Pseudomonas aeruginosa in different wastewater media composed to mimic the possible constituents of restaurant wastewater was investigated in this study. There was noticeable microbial growth in the synthetic and domestic wastewaters after 48h while the detergent wastewater and heated oil-detergent wastewater did not support the strain's growth. The decrease in the fat content with a corresponding increase in the ash content after 120h was due to the test strain's metabolic activity, which is slightly higher in domestic wastewater than the heated oil-detergent solution. Also, the potassium (K+), Mg2+, Fe2+ and Ca2+ contents increased within the same period in both media except in the domestic wastewater where the Ca2+ content reduced. Protease enzyme activity (46.440mM/min) was considerably higher in the domestic wastewater than lipase (3.322mM/min) and amylase activity (14.244mM/min) after 72 hours of incubation. The pristine genetic properties of Pseudomonas aeruginosa altered when cultured in various wastewaters probably due to variation in the composition of the substrates

An Appraisal of Ozone Layer Depletion and Its Implication on the Human Environment

Ozone layer depletion is a reality which poses threat to human survival if not curtail. However, it has received international attention and cooperation in which nation states have come up with series of conventions and protocols. It is no more gainsaying that the protection of the environment is a duty of all as no one can be left behind.This paper examines the ozone depletion substance, the impacts and implications of ozone layer depletion on human health and environment, and possible suggestion out of the challenges. The methodology adopted is basically doctrinal with primary sources from various international instruments relating to ozone layer depletions. The secondary sources are mainly from articles in journals, commentaries and online publications.It is our humble conclusion that ozone layer protection is a global and continuous assignment in which all hands must be on deck in order to meet the desirable target. The international communities’ cooperation in this regard is commendable. DOI: 10.7176/JLPG/83-02 Publication date:March 31st 201

Numerical Investigation and Improvement of Aerodynamic Performance of Savonius Wind Turbine

Higher demand for energy has lead to increase in the consumption of conventional energy which has become more expensive and scarce. There is the need to generate power from renewable sources to reduce the demand for fossil fuels and growing concern due to increase in the effects of climate change, such as global warming and acid rain generated by extensive and deliberate use of fossil fuels in the electric generating plants and transport system. In this work, the aerodynamic characteristics of Savonius wind turbine were investigated numerically by varying the rotor configuration (semi-circular and segment of circle) and overlap ratio so as to obtain the optimum design configuration which could give better performance of Savonius rotor. Comparison between the static torque coefficient at different overlap ratios of 0%, 20%, and 40% for the two configurations were studied using Solidworks CFD software. The flow around the rotor with overlap ratio variation was analyzed with the help of velocity, pressure contours and static torque coefficient equation of the rotor. It was observed from the analysis that the overlap of 20% was the optimum overlap condition at which pressure, velocity differences and coefficient of static torque across the rotor were the highest for both configurations and that segment of a circle produced the highest characteristics for better performance. Keywords: Overlap ratio, aerodynamic, Savonius, Static torque coefficient, rotor configuration

The Epidemiology of First-Episode Psychosis in Early Intervention in Psychosis Services: Findings From the Social Epidemiology of Psychoses in East Anglia [SEPEA] Study

OBJECTIVE: Few studies have characterized the epidemiology of first-episode psychoses in rural or urban settings since the introduction of early intervention psychosis services. To address this, the authors conducted a naturalistic cohort study in England, where such services are well established. METHOD: All new first-episode psychosis cases, 16-35 years old, presenting to early intervention psychosis services in the East of England were identified during 2 million person-years follow-up. Presence of ICD-10 F10-33 psychotic disorder was confirmed using OPCRIT [operational criteria for psychotic illness]. Incidence rate ratios were estimated following multivariable Poisson regression, adjusting for age, sex, ethnicity, socioeconomic status, neighborhood-level deprivation, and population density. RESULTS: Of 1,005 referrals, 687 participants (68.4%) fulfilled epidemiological and diagnostic criteria for first-episode psychosis (34.0 new cases per 100,000 person-years; 95% CI=31.5-36.6). Median age at referral was similar for men (22.5 years; interquartile range: 19.5-26.7) and women (23.4 years; interquartile range: 19.5-29.1); incidence rates were highest for men and women before 20 years of age. Rates increased for ethnic minority groups (incidence rate ratio: 1.4; 95% CI=1.1-1.6), as well as with lower socioeconomic status (incidence rate ratio: 1.3; 95% CI=1.2-1.4) and in more urban (incidence rate ratio: 1.4;95%CI=1.0-1.8) and deprived (incidence rate ratio: 2.1; 95% CI=1.3-3.3) neighborhoods, after adjustment for confounders. CONCLUSIONS: Pronounced variation in psychosis incidence, peaking before 20 years old, exists in populations served by early intervention psychosis services. Excess rates were restricted to urban and deprived communities, suggesting that a threshold of socioenvironmental adversity may be necessary to increase incidence. This robust epidemiology can inform service development in various settings about likely population-level need

Effect of Gender and Clinical Self-Efficacy on Professional Competency among Community Health Workers in Ekiti State

This research investigated the effect of gender and clinical self-efficacy on professional competence among health workers in Ekiti State. A cross-sectional survey design was used for the study. A sample of 246 community health workers across twenty four hospitals in Ekiti State was sampled using questionnaire. It comprised different cadres of community health workers. Three research hypotheses were generated in line with the study objectives. 2 X 2 ANOVA was used to test the main and interaction effects of gender and clinical self-efficacy on professional competency of the participants. Result indicated that clinical self-efficacy had significant main effect on professional competency of the participants [F (1, 245) = 5.716; P <. 05]. However, gender did not have significant main effect on professional competency of the participants. Results showed that there was no significant interaction effect of gender and clinical self-efficacy on professional competency of the community health workers in Ekiti State. The findings were discussed in line with other related works and it was recommended that urgent intervention strategies by policy makers to help community health workers develop the capacity for efficiency and feedback, in enhancing their success in their professional practices should be put in place

Ethnic Minority Status, Age-at-Immigration and Psychosis Risk in Rural Environments: Evidence From the SEPEA Study.

Objective: Several ethnic minority groups experience elevated rates of first-episode psychosis (FEP), but most studies have been conducted in urban settings. We investigated whether incidence varied by ethnicity, generation status, and age-at-immigration in a diverse, mixed rural, and urban setting. Method: We identified 687 people, 16-35 years, with an ICD-10 diagnosis of FEP, presenting to Early Intervention Psychosis services in the East of England over 2 million person-years. We used multilevel Poisson regression to examine incidence variation by ethnicity, rural-urban setting, generation status, and age-at-immigration, adjusting for several confounders including age, sex, socioeconomic status, population density, and deprivation. Results: People of black African (incidence rate ratio: 4.06; 95% confidence interval [CI]: 2.63-6.25), black Caribbean (4.63; 95% CI: 2.38-8.98) and Pakistani (2.31; 95% CI: 1.35-3.94) origins were at greatest FEP risk relative to the white British population, after multivariable adjustment. Non-British white migrants were not at increased FEP risk (1.00; 95% CI: 0.77-1.32). These patterns were independently present in rural and urban settings. For first-generation migrants, migration during childhood conferred greatest risk of psychotic disorders (2.20; 95% CI: 1.33-3.62). Conclusions: Elevated psychosis risk in several visible minority groups could not be explained by differences in postmigratory socioeconomic disadvantage. These patterns were observed across rural and urban areas of our catchment, suggesting that elevated psychosis risk for some ethnic minority groups is not a result of selection processes influencing rural-urban living. Timing of exposure to migration during childhood, an important social and neurodevelopmental window, may also elevate risk
