Leadership, Corporate Governance and Entrepreneurship Development in Nigeria:A Mutual Link

The study empirically examined the mutual link between Leadership, Corporate Governance and Entrepreneurship development in Nigeria using primary data by employing structure questionnaires to obtain information from the respondents in Lagos State as a population representative. In this research questionnaire were analyzed and interpreted using simple percentage table for tabular analysis and Spearman’s Rank Correlation Coefficient for the testing of the formulated hypotheses so as to know more about the topic understudy. It was proved in the research carried out that, effective leadership and good corporate governance determines the success of an organization. In the analysis, corporate governance policy has really helped Nigerian entrepreneur to grow financially. Also, effective leadership and good corporate governance was seen as a solution tools for global financial crises. We therefore recommend that, effective leadership and good corporate governance remains a solution tool for global financial crises, organizational problems and the right policy that enhances increased productivity that brings about economic growth and development globally. Key Words: Leadership, Governance and Productivity

Hydrocarbon Play Assessment of “Oswil” Field,Onshore Niger Delta Region

Hydrocarbon play assessment of any field involves the evaluation of the production capacity of hydrocarbon reservoir unit in the field. This involves detail study of the reservoir petrophysical properties and geological interpretation of structures suitable for hydrocarbon accumulation in the field as observed from seismic reflection images. This study details the assessment of hydrocarbon play in OSWIL field onshore in Niger Delta, with the intent of appraising its productivity using a combination of seismic, well logs,petrophysical parameters and volumetric estimation using proven techniques which involves an integrated methodology. Two reservoir windows “R1” and “R2” were defined from five wells OSWIL-02, 04, 06, 07 and 12.The top and base of each reservoir window was delineated from the wells.Structural interpretation for inline 6975 revealed two horizons (X and Y) and eight faults labelled (F1, F2, F6, F8, F10, F16, F17 and F18). Five faults (F1, F6, F10, F17 and F18) were identified as synthetic faults and dip basin wards while three faults (F2, F8 and F16) were identified as antithetic faults and dips landwards. Time-depth structural map at top of reservoirs R1 and R2 revealed structural highs and closures. These observations are characteristics of growth structures (faults) which depicts the tectonic style of the Niger Delta. Results of petrophysical evaluation for reservoirs “R1” and “R2” across the five wells were analysed. For reservoir “R1” effective porosity values of 27%, 26%, 23%, 20% and 22% were obtained for wells OSWIL-04, 12, 07, 06 and 02 respectively with an average of 23.6%, while for reservoir “R2” effective porosity values of 26%, 22%, 21%, 24% and 23% for wells OSWIL-04, 12, 07, 06 and 02 were obtained respectively with an average of 23.2%. This porosity values correspond with the already established porosity range of 28-32% within the Agbada formation of the Niger Delta. Permeability index of the order (K > 100mD) were obtained for both reservoirs across the five wells and is rated very good. Hydrocarbon saturation (Shc) across the five wells averages at 61.6% for reservoir “R1” and 67.4% for reservoir “R2”. Result of petrophysical model for porosity, permeability and water saturation reveal that the reservoir system in R1 and R2 is fault assisted and fluid flow within both reservoirs is aided by presence of effective porosity and faulting. Volumetric estimation for both reservoirs showed that reservoir R1 contains an estimate of 455 × 106 STB of hydrocarbon in place, while reservoir R2 contains an estimate of 683 ×106 STB of hydrocarbon in place. These findings impact positively on hydrocarbon production in the field and affirm that the two reservoirs R1 and R2 are highly prospective

Women’s perception on rights during pregnancy and childbirth

Background: The Nigerian health system as a whole has been plagued by problems associated with the quality of service, including but not limited to unfriendly staff attitudes to patients, inadequate skills, decaying infrastructures, and chronic shortages of essential drugs. Approximately two-thirds of all Nigerian women deliver outside of health facilities and without the presence of medically skilled attendants.  The study was carried out to assess the awareness and knowledge of women regarding their rights during pregnancy and childbirth, and to explore the extent to which women’s rights were respected during pregnancy and childbirth.Methods: This descriptive study was conducted among randomly selected 140 women at Mother and Child Hospital, Akure, Ondo state, Nigeria. Data was collected with a pretested questionnaire and was analysed using Statistical Packages for Social Sciences (SPSS) version 21.Results: Findings revealed that majority (76.9%) of the women had a fair knowledge of their rights in pregnancy and childbirth, with the source of knowledge majorly from their friends. Right to information, informed consent and refusal, even distribution of healthcare services, maintenance of attainable level of health regarding proper monitoring were fairly observed by the health care providers. Right of women against verbal and physical abuse, privacy, treatment with dignity and respect were least accorded to women.Conclusions: Respective Maternity Care remains a challenge that demands policy interventions in most public health facilities to enhance positive endorsement and utilisation of maternal and health care services

Seismic Interpretation and Petrophysical Analysis for Evaluation of Ataga Field, Onshore Niger Delta, Nigeria

The majority of geophysical survey in hydrocarbon exploration and production sector is driven by the ability to describe reservoirs. This research is aimed at describing the interpretation and petrophysical analysis of the reservoirs in Ataga field Niger Delta using a combination of seismic and well-log data. The Ataga Field in the Niger Delta was subjected to 3-D seismic interpretation and petrophysical study to perform comprehensive structural interpretation, prospect evaluation, and volumetric calculation. Two reservoir windows “1” and “2” were identified and correlated from four wells ATA 10, ATA 11, ATA 5 and ATA 7. Detailed evaluation was done on well ATA 11 since it is the only well that has sufficient data for both qualitative and quantitative interpretation. Structural interpretation for inline 5731 revealed fifteen faults on the seismic vertical section through ATA 11, most of which are antithetic faults while the rest are synthetic faults. Top and base of each reservoir window was delineated from the well. Result of the petrophysical assessment of reservoir A, B and C for ATA 11 revealed that the porosity values range from (24 -29) % which are indicative of very good to excellent porosity value according to Rider (1996). While the permeability values range from (1887-2582) mD were obtained from the three reservioir A, B and C of ATA 11 which depict very good to excellent reservoir units. Since, .all of the wells were discovered to have hydrocarbon-bearing reservoir formations (sandstones), the integration of structural interpretation and well logs have successfully revealed that the reservoirs are mostly oil-bearing zones

The relationship between hysterosalpingography findings and female infertility in a Nigerian population

Purpose: This study aims to explore the relationships between abnormal hysterosalpingography (HSG) findings and all types of infertility. Material and methods: This retrospective study was carried out at a private radiodiagnostic centre in Lagos, Nigeria. The radiologist reports of all consecutive patients who had HSG evaluation from 2016 to 2018 were analysed. Biodemographic information and indications for HSG evaluation were also documented. Logistic regression was used to test correlations between the explanatory and outcome variables. P ≤ 0.05 represented a statistically significant result. Results: A total of 450 patients were involved in this study, with ages ranging from 21 to 51 years and a mean age of 34.6 ± 5.56 years. The age group 31-35 years had the highest frequency of infertility. There were 299 patients referred for infertility. Secondary infertility was seen in 211 patients (46.9%), primary infertility was seen in 79 patients (17.6%), and subfertility was seen in nine patients (2%). There were 49 patients (10.9%) with cornual tubal blockage, while 57 patients (12.7%) had perifimbrial adhesion and/or blockage. There were 56 patients (12.4%) with hydrosalpinx and nine patients (2.0%) with tubal occlusion. Multivariate logistic regression analysis showed women with hydrosalpinx were 2.11 times more likely to be infertile than those without hydrosalpinx (95% CI: 1.02-4.36, p = 0.042). Conclusions: The presence of hydrosalpinx was a significant risk factor in developing all types of infertility. Understanding the HSG patterns and their correlations with infertility will help physicians across the world when evaluating infertility in patients of similar background to our patient population

Assessment of Subsurface Competency Using Geotechnical Method of a Proposed Structure F.C.T Nigeria

Structural failure has been recently happenings mostly in the commercially populated states along the coastal line in Nigeria. As a result, an open field at a chosen location in Abuja, Nigeria, was investigated. For the purpose of this study, test bores were drilled and Standard Penetration Tests (SPT) were conducted at every 1.5 m interval up to a maximum depth of 12.0 m with the bearing pressure ranging between 20 kN/m2 and 1000 kN/m2 . 3 test bores’ were drilled within the plot location, and samples were obtained at the test bores locations for laboratory analysis. Findings revealed that subsurface lithology found at the site within the explored depths of 0.0 ~ 12.0 m is mostly silty sand, laterite, sandy clay, silty clay, clayey sand, and weathered rock. The findings from the sub-soils of the different places and their bearing pressures were computed with SPT N value. Building foun dations may be rigid raft foundations at a depth of 2.0 meters below the present ground level, according to bearing capacity values that range from 20 kN/m2 to 60 kN/m2 at 1.5 to 3.0 meters. The recommended building foundations take into account the sub-soil’s characteristics at the drilling places at a depth of between 1.0 and 3.0 meters. The structure might also be supported by frictional piles buried 10 meters beneath the surface.

A Case for the Adoption of an In-Memory Based Technique for Healthcare Big Data Management

In healthcare organizations, the amount of data that are generated daily are on the increase with every visit by patient. The generated data through vital signs’ readings such as body temperature, pulse rate, respiratory rate, blood pressure, body weight among others are now accumulated into big data. Recently, the growth of data is averaged at about 35 percent annually. The implication is that the amount of storage needed to hold the data doubles within a period of three years. No doubt, if these data are processed and analyzed properly, it holds immense value in diagnosis and predictive medical conditions. However, the ever increasing volume of data has brought with it some big challenges. One of such is how healthcare organizations are going to store and access the vast amount of inherent information. In this paper, we discussed the need for storing medical Big Data in the main memory (In-Memory) as a way of addressing storage and access to information challenges of big data in health care delivery system.  With current trends in technology advancement, there is an availability of storage systems with increased memory capacities. The storage of data in main memory can achieve a performance improvement of up to a factor of 100,000 or more. With this achievable performance, In-Memory Data Management proves to be a viable option

Small vessel disease disrupts EEG postural brain networks in 'unexplained dizziness in the elderly'

Objective: To examine the hypothesis that small vessel disease disrupts postural networks in older adults with unexplained dizziness in the elderly (UDE). / Methods: Simultaneous electroencephalography and postural sway measurements were undertaken in upright, eyes closed standing, and sitting postures (as baseline) in 19 younger adults, 33 older controls and 36 older patients with UDE. Older adults underwent magnetic resonance imaging to determine whole brain white matter hyperintensity volumes, a measure of small vessel disease. Linear regression was used to estimate the effect of instability on electroencephalographic power and connectivity. / Results: Ageing increased theta and alpha desynchronisation on standing. In older controls, delta and gamma power increased, and theta and alpha power reduced with instability. Dizzy older patients had higher white matter hyperintensity volumes and more theta desynchronisation during periods of instability. White matter hyperintensity volume and delta power during periods of instability were correlated, positively in controls but negatively in dizzy older patients. Delta power correlated with subjective dizziness and instability. / Conclusions: Neural resource demands of postural control increase with age, particularly in patients with UDE, driven by small vessel disease. / Significance: EEG correlates of postural control saturate in older adults with UDE, offering a neuro-physiological basis to this common syndrome

Analysis of potentially toxic elements from selected mechanical workshops using the geo‑accumulation index and principal component analysis in Omu‑Aran Community, Nigeria

Bioaccumulation of potentially toxic ele�ments in soil threatens public health and the ecosystem. This study aims to assess the concentration of potentially toxic elements (chromium (Cr), lead (Pb), iron (Fe), arsenic (As), and cadmium (Cd)) in selected automobile workshop premises in Omu-Aran, Nigeria. Forty-eight samples were collected at a depth (15 cm) in six locations, including a control point. Acid digestion was carried out to prepare the soil samples before assessing their concen�tration via an atomic absorption spectrophotometer. Geo�accumulation index (Igeo) was used to classify the level of contamination. Statistical analysis, which includes princi�pal component analysis (PCA) and Pearson’s correlation, was also determined. The difference in concentration was determined using ANOVA. In the study area, the low�est observed concentration values for Cr, Pb, Fe, As, and Cd, which are 0.246±0.002 mg/kg, 0.178±0.001 mg/ kg, 90.715±0.038 mg/kg, 0.012±0.004 mg/kg, and 0.078±0.004 mg/kg, respectively, are relatively higher than observed for the control. The observed potentially toxic elements fall within three Igeo based on Muller’s interpretation; heavily to extremely contaminated (Cd), moderately to heavily contaminated (Pb, Cr, and As), and uncontaminated to moderately contaminated (Fe). PCA shows that two principal components (PC) account for up to 91.052% of the original mean dataset variability. PC1 explains 67.723% of the total variance associated with Cd, Cr, Fe, Pb, and As, indicating anthropogenic is the primary source of these potentially toxic elements. The PC2 accounted for 23.329%, with Pb and As significant contributors. Cadmium contamination of soil was the most influential, with an Igeo value ranging from 4 to 5. Residents in the polluted region face considerable health risks from potentially toxic elements.
