O. H. Ezeh, C. C. Ezeh
Open Journal of Medical Psychology (OJMP) , 2017, DOI: 10.4236/ojmp.2017.64018
Abstract: Introduction: It is estimated that more than 330 million persons are living with HIV-infection globally and in Nigeria about 3.4 million persons are living with the infection, with an annual death rate of 180,000. Psychological morbidity often accompanies chronic illnesses and may be associated with substance abuse, poor health seeking behaviour and adherence to treatment program; it may worsen existing health problems and the overall quality of life. Until the burden is effectively identified, intervention cannot be planned. Until there is cure, the goal is to manage and cope effectively with HIV-infection. Little if any studies have been done in this area in the North West geopolitical zone of Nigeria, the study would help to identify high risk groups and prevent the progression and spread of the infection. Objectives: To identify HIV-infected persons with psychological morbidity, accessing HIV-clinic at Shika Hospital, Zaria, Kaduna State; and analyze their socio-demographic profile. Methodology: A cross sectional descriptive study was carried out to assess and analyze the socio-demographic characteristics of HIV-infected persons attending Shika hospital Zaria Nigeria, who screened positive for psychological morbidity. A total of 109 HIV-infected persons receiving HAART at Shika clinic, Zaria, Kaduna State, Nigeria, were administered questionnaires; the General Health Questionnaire (GHQ-12) measuring psychological morbidity and socio-demographic data. The participants ranged in age between 18 and 75 years. Results: Data were analyzed using SPSS software 15. Both descriptive and inferential Statistics were performed on the data. Results indicate a total prevalence rate of psychological morbidity of 78 percent among participants. Of this, about 16.2 percent were severely distressed, 25.1 percent moderately distressed and 36.7 percent were mildly distressed. The females were more likely to be distressed than men (65 percent vs. 35 percent of those with psychological morbidity, OR = 3.5 CI 95 percent). It was (57 percent) for patients whose HIV-infection was of relatively shorter duration (less than 4years) than (43 percent) those of longer duration (5 years and above; OR = 1.7, CI 95 percent = 1.1 - 3.5). The age group (18 - 40 years) was more likely to screen positive for psychological morbidity (58.3 percent vs. 41.7 percent, OR = 2.4, CI 95 percent), than the age group (41 - 75 years). On the other hand, Christians were more likely than Muslims (55 percent vs. 45 percent, OR = 1.5, CI 95 percent = 1.1 - 3) to be distressed. For married patients with
Perception and Information Seeking Behaviour of Rural Households towards Health Promoting Practices in Maigana District of Kaduna State, Nigeria  [PDF]

Open Journal of Medical Psychology (OJMP) , 2017, DOI: 10.4236/ojmp.2017.64019
Abstract: Information is valuable, increases understanding and reduces uncertainty. Limited knowledge and access to health promoting and disease prevention programmes are more pronounced in rural than urban areas of Nigeria. Furthermore, the paucity of healthcare services in these rural communities also contributes to the prevalence of health challenges in the rural sector. This study investigated the perception and information seeking behavior of rural households in Maigana District of Kaduna State, Nigeria towards health promoting practices. A random sample of 152 respondents selected from five of eleven wards in the district was interviewed using a pre-tested structured questionnaire. The results, based on a 4-point Likert type scale and benchmark of 2.5 showed a very poor perception of health promoting practices among the respondents. Also, the information needs of the respondents were shown to be enormous. Three of the six socio-demographic variables regressed were found to significantly influence the information seeking behavior of the respondents regarding health promoting practices. Constraints limiting the embracement of health promoting practices were identified and measures aimed at promoting healthier living standards in rural communities were recommended. The study concludes that vast knowledge gaps do exist coupled with the poor perception of HPPs by the respondents.
Correlates and Predictors of Psychological Morbidity in HIV-Infected Persons: A Cross Sectional Study  [PDF]
O. H. Ezeh, C. C. Ezeh
Open Journal of Medical Psychology (OJMP) , 2019, DOI: 10.4236/ojmp.2019.84006
Abstract: Introduction: HIV-infection is associated with many factors including: physical, social, cultural and psychosocial factors. Physiological changes associated with HIV infection may generate psychological morbidity. However, specific psychosocial factors contributing to psychological morbidity remain unclear. Identifying factors contributing to psychological morbidity may help in prevention and planning intervention. Aims/Objectives: 1) To identify significant predictors of psychological morbidity from specific dysfunctional coping traits/dimensions among HIV-infected persons; 2) To assess/determine the association between predictor variables (specific coping dysfunctional traits) and psychological morbidity; 3) To identify other correlates of psychological morbidity; 4) To make recommendations on how to reduce levels of dysfunctional coping and psychological morbidity. Methods: This cross-sectional descriptive study was conducted to examine data collected from 110 participants, HIV patients receiving HAART services from Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Kaduna State, Nigeria. Results: Results indicate that HIV-patients with high levels of psychological morbidity were more likely to use dysfunctional coping more frequently. Therefore, greater psychological distress and symptoms reporting may be associated with dysfunctional coping. Conclusion/Recommendation: The study recommends that specific dysfunctional coping dimensions should also be targeted in interventions designed to reduce psychological morbidity in HIV patients.
OPTIMIZATION OF COMPRESSIVE STRENGTH OF FLY ASH BLENDED CEMENT CONCRETE USING SCHEFFE’S SIMPLEX THEORY
L. Anyaogu,J. C. Ezeh
Academic Research International , 2013,
Abstract: High cost of cement as a major component of concrete has contributed to continuous rise in the cost of concrete works in Nigeria and other developing nations. Blended cement has become quite popular in developed countries due to its durability and high benefits / cost ratio. Fly ash as a residue resulting from combustion of pulverized coal or lignite occurs in large quantities in some parts of Nigeria.Generally, mix proportions of the various components determine the compressive strength and other properties of concrete. In this study, a mathematical model was developed for optimizing the compressive strength of fly ash blended cement concrete based on Scheffe’s Simplex Polynomial theory. A total of ninety (90) cubes were cast,consisting of three cubes per mix ratio and for a total of thirty (30) mix ratios. The first fifteen (15) were used to determine the coefficients of the model, while the other fifteen were used to validate the model. The five component second degree (5, 2)mathematical model compared favourably with the experimental data and the predictions from the model were tested with the statistical Fischer test and found to be adequate at 95% confidence level. The optimum compressive strength of the blended concrete at twenty-eight (28) days was found to be 43.152 N/mm2. This strength corresponded to a mix ratio of 0.549:0.935:0.065:1.760:3.52 for water: cement: fly ash: sand: granites respectively. The model derived in this study can be used to predict mix ratios for any desired strength of fly ash blended cement concrete within the factor space of the simplex used in the study and vice versa.

American Journal of Analytical Chemistry (AJAC) , 2017, DOI: 10.4236/ajac.2017.86031
Abstract: The proximate, elemental and phytochemical compositions of the leaves of Pterocarpus soyauxii (Oha) were studied. The results obtained for the proximate composition showed the following: moisture content (17.2%), ash content (5.7%), crude fibre (17.2%), crude protein (29.5%), crude fat (4.15%) and carbohydrates (25.95%). The results of the mineral (elemental) analysis in mg/L showed the following to be present in the leaves: Ca (4.04), Cu (0.20), Zn (1.39), Mg (41.0), K (0.31), Mn (0.17), Na (32.0) and Fe (0.60) with Pb and Cr absent. The leaves also contained vitamin A (0.2044 mg/g) and vitamin C (0.4470 mg/g). The phytochemical analysis of different solvent extracts showed the presence of alkaloids, saponins, glycosides and tannins. Flavonoids, phenols and steroids were absent. These findings showed that the leaves of Pterocarpus soyauxii are good sources of beneficial micronutrients, mineral elements and secondary metabolites which are required for healthy growth, justifying the use of the leaves for the popular “Oha” soup of the Igbos of South East Nigeria.

Journal of Agricultural Chemistry and Environment (JACEN) , 2019, DOI: 10.4236/jacen.2019.81003
Abstract: The effect of anthropogenic activity relating to industrial and economic development has had a detrimental impact on the environment and human health, and hence the need for continued research. Five common African vegetablesMurraya koenigii, Ocimum gratissimum, Amaranthus hybridus, Capsicum annuum and Moringa oleifera were used to study absorption of Lead, Cadmium, Cobalt and Zinc from soils inoculated with metal ions. 0.1 M and 0.5 M solutions of the metal ions were used in the inoculation. Each of the plants was collected in the first instance at 8 weeks, and then at 10 weeks of inoculating. Atomic Absorption spectrophotometer was used to determine the metal ions concentrations absorbed in the plants. Cd2+ was most and Moringa oleifera the least absorbed of the four metal ions, with a highest value of 34.801 ± 0.805 mg/kg occurring in Capsicum annuum. Co

Academic Research International , 2013,
Abstract: Compared with conventional structural plates, the pronounced role of instability complicates the behaviour of thin-walled plates. In this study, the stability of in-plane loaded CCCC thin-walled rectangular plate was investigated. The study involved a theoretical formulation based on Taylor-McLaurin series as shape function and implemented through application to Ritz method. In deriving the shape function,Taylor-McLaurin series was truncated at the fifth term, which satisfied the boundary conditions of the plate and resulted to a particular shape function for CCCC plate. The shape function was then substituted into the total potential energy functional,which was subsequently minimized to get the stability equations. Derived Eigen-value solver was used to solve the stability equation for CCCC plates various aspect ratios to get the buckling loads. The buckling loads from this study were compared with those of earlier researchers and the average percentage difference recorded forCCCC plate was 3.54%. This difference shows that the shape function derived from Taylor-McLaurin series has rapid convergence and is a very good approximation of exact displacement function of the deformed thin-walled rectangular plate under inplane loading.

Abstract: As enrollment of students into tertiary education in Nigeria continues to increase, the need for an efficient and speedy method of measuring academic performance of students has become more significant. This study designed and implemented a Micro-Controller based cumulative Grade Point Average (MICGPA) Software calculator for easy and speed computation of CGPA of students. The aim of the study is to present a novel high speed, hand operated and cheap software calculator for processing students’ results. The software development process adopted modular technology in which each module has specific structure and function. In this study, the design depends on Micro-Controller (AT895S2) for the control, processing andstorage functions. The software was developed based on High level C-language and compiled using Resonance Integrated Development Environment (RIDE). Results of computations with the new software calculator were found to agree with the manually computed results with a higher degree of precision.

Nigerian Veterinary Journal , 2007,
Abstract: The efficacy of increasing doses (3.5, 7.0, 14, and 21 mg/kg) of Samorenil ; a diminazene based trypanocide was investigated in albino rats experimentally infected with Trypanosoma brucei. Thirty albino rats were used for the study. The rats were divided into six groups of five rats each. Groups III, IV, V, VI were infected with 1.0 x 106 trypanosomes intraperitoneally and were later treated at day 9 post infection with 3.5, 7.0, 14 and 21 mg/kg of samorenil respectively. Group I served as negative control (uninfected untreated) while Group II served as positive control (infected untreated). The parameters monitored for the therapeutic assessment of the increasing doses of Samorenil were parasitaemia, rectal temperature, packed cell volume (PCV), and body weight. Following treatment, there was complete aparasitaemia at 96 hours post treatment in all the infected treated rats. There was also an improvement in the clinical condition of the experimental rats. Four rats in the positive control (group II) (infected untreated) died by day 35 post infection and the remaining one died at day 70 post infection. Relapse infection however occurred at days 35, 49, and 63-post treatment in groups treated with 3.5, 7.0, and 14 mg/kg respectively. There was no relapse infection in the group treated with 21 mg/kg. It was thus concluded that there may be merit in using higher doses of Samorenil in the treatment of trypanosomosis. The possible toxic effect of these higher doses however needs to be further investigated to ascertain the safety or otherwise of the higher doses used.

Academic Research International , 2013,
Abstract: Earlier solutions on pure bending of thin rectangular flat plates were based on the use of trigonometrical series. However, series method has the problem of improper representation of deformed shape of plate in vibration. For such problems, the use of numerical methods for approximate solutions becomes necessary. In this study, Ordinary Finite Difference method (OFDM) as one of the popular numericaltechniques was used in free vibration (FB) analysis of thin rectangular flat plate. The differential equations of the biharmonic plate were transformed to fit the chosen grid pattern and these transformed equations were expressed in finite difference (FD)form. These differences were evaluated at each nodal point to obtain a set of simultaneous algebraic equations that were solved for the unknown functional values after using the proper boundary conditions of SSSS, CCCC and CSCS respectively. Visual Basic (VB) software program was developed and used in solving the algebraic equations, while the resulting natural frequencies , were compared with the exactvalues for an aspect ratio of 1.0 as shown in tables 1, 2 and 3 respectively. The solutions obtained in this study approximated closely to the exact solutions as shown in the tables. Hence, ordinary finite difference method (OFDM) provides simple and approximate solutions that are very close to exact values for this family of problems.
