Abstract

BACKGROUND: The study aimed to examine psychopathic deviant attributes and psychophysiological symptoms among undergraduate students of Rivers State University, Port Harcourt. METHODS: This cross-sectional study sampled 43 undergraduate students (400 level psychology students) from Rivers State University (11.6% males, n = 5, 88.3% females, n = 38) between the ages of 19 and 33 years (mean age = 22.8 years, SD = 2.23). The psychopathic deviate scale by Hathaway and Mckinley (1967) and the psychophysiological symptoms checklist by Omoluabi (1987) were used to gather participants' data. Three hypotheses were tested. RESULTS: Findings showed that females did not present a significantly (p > .05) higher score than males in psychopathic deviate attributes (females χ² = 21.1316, males χ² = 22.4000, t = 454, df = 41) and in psychophysiological symptoms (females χ² =77.0000, males χ² = 83.9211 t = -.386, df = 41). Psychopathic deviant attributes also showed a significant positive correlation with psychophysiological symptoms (r = .591, p <.01) among the studied undergraduate students. The study affirmed that both genders are similar in their manifestation of psychopathic deviant traits and psychophysiological symptoms. CONCLUSION: The study confirmed results from previous studies on the prevalence of psychopathic deviant traits and psychophysiological symptom variables among young people. [ABSTRACT FROM AUTHOR]

Abstract

Oil palm is known to utilize a high amount of soil nutrients for optimum growth and development. Nutrient management is paramount to the production of high fruit bunch hence the reason for this study is to evaluate the fertility status of selected oil palm plantation in Ondo west Local Government Area. Two different species of oil palm (hybrid and non-hybrid species) were investigated for their physiochemical parameters. Soil samples from non-hybrid (B) recorded N, P and K content below the critical nutrient (NPK) content for oil palm tree. The nutrient availability index indicated a low nutrient availability of TN, OM, P and Mg for soil samples from non-hybrid (B). Therefore proper nutrient management approaches such as the application of inorganic fertilizer should be adopted especially for nutrients that are deficient and low from non-hybrid (B).

Abstract

The geomechanical characterization of the reservoirs of "Beta Field" was carried out to predict the stability of hydrocarbon reservoir rocks and hence, mitigate drilling and exploitation challenges within offshore Niger Delta. Gamma ray, sonic, and density logs from four wells within the field, including core data and 3D reflection seismic volume from the area, were integrated to determine rock mechanical and petrophysical properties from empirical equations, and generate 3D geomechanical models using Petrel and Ms-Excel software. Principal stresses operating within the reservoirs and pore pressure were also estimated from empirical models. Cross plots of these rock parameters were obtained to ascertain the relationship between them and obtain model equations. Results show that the rock mechanical properties have lower values in sand units than shale units with petrophysical parameters having lower values in shale. Average values of 13.70GPa, 0.33, 13.30GPa, 32.32GPa, 5.12GPa, 0.07, and 0.022mD were obtained in shale; while 0.30, 10.94GPa, 0.30, 12.76GPa, 25.19GPa, 4.11GPa, 0.19, and 192.00mD were recorded in sand for Young's modulus, Poisson ratio, bulk modulus, uniaxial compressive strength, shear modulus, effective porosity, and permeability respectively. Mean pore pressures observed in sand and shale units are 13,683psi and 15,662psi while mean total vertical stress, maximum and minimum horizontal stresses recorded in the reservoirs are 28,392psi, 25,537psi and 20,781psi respectively. Comparative analysis of obtained rock mechanical and strength parameters with the principal stresses operating within the reservoirs show that the studied reservoirs and by extension reservoirs of this petroleum play are stable.

Abstract

This research was carried out to ascertain the impacts of land use on water quality in Ala river within Akure metropolis, Nigeria. Physical, chemical and bacteriological tests were carried out on the water samples collected from eight different sample points along the river. The parameters analyzed were temperature, odour, taste, colour, turbidity, nitrite, nitrate, pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), phosphorus, chlorine, and heavy metals which include copper, cobalt, iron, nickel, zinc, arsenic, selenium, manganese and lead. All the samples indicated contamination alongside the presence of heavy metals. COD values of 160, 300, 580, 220, 400 and 120mg/L observed in points 2, 3, 5, 6, 7, and 8 respectively were above the WHO permissible limit. In point 1, the concentration of heavy metals like iron and lead were above the safe limit. The result showed that amongst the human activities identified to cause water pollution, improper waste disposal and uncontrolled agricultural activities had major effects. [ABSTRACT FROM AUTHOR]

Abstract

The water quality assessment in First Baptist Church, Offa, Kwara State Nigeria was carried out by examining nine samples in and around the church premises. One surface water sample, five borehole water samples and three well water samples were examined. The result obtained from the physicochemical analysis showed a turbidity range of (2-6NTU), electrical conductivity EC (693-893 µs/cm), total dissolved solids TDS (346-542mg/L), pH (6.83-7.62), magnesium Mg (17-53mg/L), manganese Mn (0.02-0.1), aluminium Al (0.02-0.13mg/L), iron Fe (0.10-0.44mg/L), zinc Zn (0.8-3.60mg/L), chromium Cr (0.02-0.13mg/L), lead Pb (0.01-0.04), Sulphate SO4 (3-20mg/L), Nitrate NO3 (3-18mg/L), phosphate PO4 (1.5-14mg/L), chlorine Cl (14-42mg/L), copper Cu (0.04-0.7mg/L), chemical oxygen demand COD (62-120mg/L), total hardness TH (80-160mg/L) and total alkalinity TA (80-136mg/L). These results, together with that of the microbial analysis were compared with the standard provided by the World Health Organization WHO. Hence, it is crucial that the water supplies are regularly assessed and properly treated to provide the consumers with safe and healthy water. [ABSTRACT FROM AUTHOR]

Abstract

The challenges of reliably collecting, storing, organizing, and analyzing research data are critical in low- and middle-income countries (LMICs), particularly in Sub-Saharan Africa where several healthcare and biomedical research organizations have limited data infrastructure. The Research Electronic Data Capture (REDCap) System has been widely used by many institutions and hospitals in the USA for data collection, entry, and management and could help solve this problem. This study reports on the experiences, challenges, and lessons learned from establishing and applying REDCap for a large US-Nigeria research partnership that includes two sites in Nigeria, (the College of Medicine of the University of Lagos (CMUL) and Jos University Teaching Hospital (JUTH)) and Northwestern University (NU) in Chicago, Illinois in the United States. The largest challenges to this implementation were significant technical obstacles: the lack of REDCap-trained personnel, transient electrical power supply, and slow/ intermittent internet connectivity. However, asynchronous communication and on-site hands-on collaboration between the Nigerian sites and NU led to the successful installation and configuration of REDCap to meet the needs of the Nigerian sites. An example of one lesson learned is the use of Virtual Private Network (VPN) as a solution to poor internet connectivity at one of the sites, and its adoption is underway at the other. Virtual Private Servers (VPS) or shared online hosting were also evaluated and offer alternative solutions. Installing and using REDCap in LMIC institutions for research data management is feasible; however, planning for trained personnel and addressing electrical and internet infrastructural requirements are essential to optimize its use. Building this fundamental research capacity within LMICs across Africa could substantially enhance the potential for more cross-institutional and cross-country collaboration in future research endeavors.

Abstract

Background information: The phytochemicals of endophytes have generated substantial interest in drug discovery programs because they offer the possibility of discovering new biologically active molecules. Objective: The objective of this study was to quantify and analyze the phytochemical profile of the fungus endophytic extracts isolated from Azadirachta indica leaves, which have been used ethnobotanically for treating malaria and bacterial infections. Methods: Endophytic fungi were isolated, solid-state fermentation of rice medium was performed, and secondary metabolites were extracted according to standard techniques. An analytical system that uses gas chromatography and flame ionization detection (GC-FID) was used to determine the phytochemical constituents contained in the endophytes. Results: The results of GC-FID analysis showed the presence of Ribalinidine, Naringenin, Sparteine, Phenol, Steroids, Kaempferol, Flavone, Oxalate, Catechin, Tannin, and Rutin at different concentrations. Conclusion: This study reveals the promising ability of the endophytic fungi of A. indica as a foundation of naturally occurring bioactive. The quantitative phytochemical assessment of the endophyte extracts from the leaves of A.indica showed that endophyte extracts from the plant are rich in both alkaloids and flavonoids (Phenolics).

Abstract

Background: In active female reproductive life, a cascade of physiological phenomena occurs during each menstrual cycle day. Aim and Objectives: The study was designed to determine the relationship between surging reproductive hormones and blood viscosity indices. Material and Methods: One hundred apparently healthy females between the ages of 18-25 years, with regular cycle length of 28 days were recruited for the study. Reproductive hormones [Luteinizing Hormone (LH) and progesterone], blood viscosity indices [Relative Plasma Viscosity (RPV), fibrinogen and hematocrit] and other blood related parameters were analyzed during days 12, 13, 14 and 21 of menstrual cycle. Results: Progesterone secretion reached nadir and zenith on days 12 and 21 respectively while peak LH level occurred on day 12. On days 12 and 21, RPV correlated with progesterone negatively while on days 12 and 13, fibrinogen was inversely related to progesterone. Hematocrit correlated positively with progesterone throughout the menstrual cycle days. Although fibrinogen and mean corpuscular volume were unchanged throughout the menstrual cycle days, RPV was high on day 13. Significant decreases in red and white blood cell counts and hematocrit were observed on day 21. Conclusion: The findings of the study indicated that blood viscosity indices were not influenced by surges in progesterone and luteinizing hormone.

Abstract

Increasing structural failures and the collapse of engineering structures as well as poor seismic data acquisition in the study area is the result of poor understanding of the characteristics/attributes of the weathered layer. To have a deep understanding of the weathered layer of Ohaji-Egbema area, twelve(12) Uphole refraction seismic survey was conducted using Seistronix seismograph with 32 channels with the specific objective of characterizing the weathered layer. The UpShere software was used to pick the first break, process and interpret the data. The results of the refraction seismic survey conducted in the study area revealed spatial variations in the depths of the weathered layer which ranged from 4.8m to 25m with a value of 10.74m, while the weathered layer velocity ranged from 346m/s to 767m/s with a mean value of 447.58m/s. The results revealed two (2) zones with distinct high weathered layer depths of 25m and 17.7m respectively. These high weathered layer depths are believed to be associated with the incidences of foundation failure and the collapse of engineering structures which generally occurs if soil improvement mechanisms are not put in place. Also, reflection seismic data acquired from the study area especially waves passing through this uncompacted and loose layer will lead to a high volume of poor seismic data. It is therefore recommended that before erecting engineering structures within these zones with high weathered layer depth, special foundation treatment is required, for other zones with moderate weathering depths between 4.8m to 10.3m, a foundation depth of 10.5m should be ensured before erecting engineering structures while a 35m - 40m depth hole would be appropriate for better seismic reflection data quality.

Abstract

Background: The prevalence of obesity is increasing worldwide with attendant chronic complications. The outcome of HIV/AIDS and its treatment is worse in individuals with coexisting overweight or obesity and its complications. Aim: To determine the prevalence of overweight and obesity among of HIV infected patients at enrollment for treatment of HIV/AIDS as well as the associated risk factors. Methods: A cross-sectional descriptive study was conducted in the Special Treatment Clinic (STC), National Hospital, Abuja. A total of 300 adult patients with HIV/AIDS were recruited by purposive sampling. An intervieweradministered questionnaire was used to obtain data on socio-economic and clinical characteristics. The body mass index (BMI) and blood pressure of the respondents were measured. Results: A total of 189 females and 111 males were studied. The mean age was 37.1 years ± 8.6 years. The mean BMI was 25.5kg/m² ± 4.8kg/m². Overweight respondents made up 32.7% of the study population while 15% of them were obese. The mean blood pressure was 117/75 ± 19/11mmHg and 55% of the respondents had normal blood pressure measurements. Amongst those with abnormal blood pressure measurements, 63% were overweight/obese. There was a significant relationship between BMI and sex (p<0.001), marital status (p<0.001), area of residence (p<0.001) alcohol use (p<0.001) and blood pressure (p<0.001). Conclusion: Overweight and obesity occur frequently among patients infected with HIV/AIDS. It is recommended that weight management and other lifestyle modification practices should be integrated into every aspect of their care. [ABSTRACT FROM AUTHOR]

Abstract

The Niger Delta Region of Nigeria is within the mangrove forest region and is crisscrossed by series of streams and creeks. As a result of the high rainfall volume within this region there is a tendency for severe flooding to occur. These flood events have severe consequences on lives and properties. It is therefore necessary to carry out a flood frequency analysis in this area in order to predict the potentials for the occurrence of flooding and take necessary measures for their remediation. In this study, peak monthly rainfall for thirty three years from 1981 - 2013 were acquired for Patani area in the Niger Delta region of Nigeria from NIMET and CBN. Five probability distributions, namely Normal, Log normal, Log-Pearson, Gumbel and Foster's Type -1 were selected for frequency analysis of the precipitation data using return periods of 2, 5, 10, 25, 50, 100 and 200 years respectively. The predicted values were subjected to goodness of fit tests using ANFIS tool in the MATLAB 7.0 software. The results of the tests and analyses show that the Gumbel Distribution best describes the precipitation data for the region and can therefore be used for the prediction of flooding within the study area followed by the Foster's Type- I distribution. The Normal Distribution was on the other hand found the least suitable for describing the precipitation data for Patani area. [ABSTRACT FROM AUTHOR]

Abstract

Groundwater resource in Ohaji Egbema, was investigated for its quality from which inferences are drawn on its usability, prevalent hydrochemical processes in the water system and probable quality degradation. Results of the field and laboratory analysis indicate a chemical attribute of low pH, total dissolved solids (TDS) and electrical conductivity (EC). Cationic concentrations including Na2+, K+, Ca2+, Mg2+ have values ranging from 5.2 - 20.3, 2 - 8, 0.96 - 9.28, and 0 - 2.3mg/l respectively whilst Anions involve NO3-, Cl-, SO42-, HCO3-, with their respective values as 8.5-20.1, 8.5-24.14, 1.48-45.07 and 8.6-16.5mg/l. Selected heavy metals tested follow the order of Mn2+ > Fe > Zn2+ > Cu2+. The water quality plots reveal a hydrogeochemical process operative within the groundwater system as relating to water-soil interaction and incorporation of leached formation water along the groundwater flow path. Illatively, other parameters suggests a low mineralized soft freshwater having a limited residence time, with an onset of degradation from biochemical related substances resulting from human activities in the area. An interplay of these processes produced a chloride water type (Na(k)Cl and Cl- + SO4-). A comparison of these results with various quality guidelines, suggests that the groundwater maybe usable in its untreated state for crop irrigation but will require pH remediation to upgrade its quality for portability and use in some industries.

Abstract

Onitsha is one of the largest commercial cities in Africa with its population growth rate increasing arithmetically for the past two decades. This situation has direct and indirect effects on the natural resources including vegetation and water. The study aimed at assessing land use-land cover (LULC) change and its effects on the vegetation and landscape from 1987 to 2015 using geoinformatics. Supervised and unsupervised classifications including maximum likelihood algorithm were performed using ENVI 4.7 and ArcGIS 10.1 versions. The LULC was classified into 7 classes: built-up areas (settlement), waterbody, thick vegetation, light vegetation, riparian vegetation, sand deposit (bare soil) and floodplain. The result revealed that all the three vegetation types decreased in areas throughout the study period while, settlement, sand deposit and floodplain areas have remarkable increase of about 100% in 2015 when compared with the total in 1987. Number of dominant plant species decreased continuously during the study. The overall classification accuracies in 1987, 2002 and 2015 was 90.7%, 92.9% and 95.5% respectively. The overall kappa coefficient of the image classification for 1987, 2002 and 2015 was 0.98, 0.93 and 0.96 respectively. In general, the average classification was above 90%, a proof that the classification was reliable and acceptable.

Abstract

Background Sexually transmitted infections and syphilis are a major public health concern. Hemodialysis patients are at an increased risk of acquiring hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. The aim of this study was to determine the seroprevalence of HBV, HCV, syphilis, and the association between these infections and hemodialysis among hemodialysis patients. Methods A cross-sectional study was conducted involving 90 hemodialysis patients. Blood samples were collected and analysed for HBV, HCV and syphilis using immunochromatographic test kits. All subjects completed a questionnaire on demographic characteristics and other risk factors. A chi-square test was used to analyse the data. Results The prevalence of HBV, HCV and syphilis infections was 4.4%, 6.7% and 2.2% respectively. Highest prevalence of HBV, HCV and syphilis were found in patients whose duration of dialysis were >1 year, >1 year, and 4 months to 1 year, respectively. Similarly, those who had undergone dialysis for > 10 times had the highest prevalence of these infections. The major risk factor the patients was exposed to was blood transfusion (100%), with those who had been transfused for 5 times having the highest prevalence of HBV and HCV and those transfused twice for syphilis. A significant association was seen between duration of dialysis and HCV infection (p

Abstract

Objective: To evaluate the influence of gingival exposure on smile attractiveness. Methods: Photograph of one male and female volunteer with gummy smile, ideal occlusion and no dental anomalies were taken and manipulated on the computer with different gingival exposure levels ranging from +4mm to -4mm. The photographs were then printed and numbered 1-10 [Male=1-5 and Female=6-10] with the relevant gingival exposure 1= +4 mm, 2= +2 mm, 3= 0 mm, 4= -2 mm, 5= -4 mm, 6= +4 mm, 7= +2 mm, 8= 0 mm, 9= -2 mm and 10= -4 mm. Assessment was independently done on each picture using 5point attractiveness scale scored as very attractive, attractive, neither attractive nor unattractive, unattractive, very unattractive. Results: The highest mean attractiveness was reported on +4mm and +2mm gingival exposure for the male picture while +2mm and +4mm gingival exposure for the female picture. The mean attractiveness for picture 1 was significantly higher in younger than older participants (4.95±0.02 versus 4.81±0.02). The mean attractiveness for picture 4 was significantly higher in dental professionals than laypersons (3.96±0.08 versus 3.09±0.06). The mean attractiveness for picture 5 was significantly higher in younger than older participants (2.04±0.06 versus 1.53±0.04) and also in laypersons than dental professionals (1.79±0.04 versus 1.34±0.05). The mean attractiveness for picture 6 was significantly higher in younger than older participants (3.18±0.09 versus 2.83±0.07), males than females (3.10±0.08 versus 2.84±0.08) and also in lay persons than dental professionals (3.16±0.06 versus 2.01±0.10). The mean attractiveness for picture 7 was significantly lower in younger than older participants (2.90±0.07 versus 3.09±0.05). The mean attractiveness for picture8 was significantly higher in younger than older participants (2.03±0.05 versus 1.85±0.04) and also in laypersons than dental professionals (1.68±0.06 versus 1.96±0.03). The mean attractiveness for picture 9 was significantly lower in younger than older participants (1.39±0.05 versus 1.54±0.03). The mean attractiveness for picture 10 was significantly higher in dental professionals than laypersons (1.36±0.06 versus 1.23±0.02). Conclusion: Smile attractiveness influenced by the gingival exposure had major variations between younger and older participants, moderate variation between dental professionals and laypersons have similar opinions regarding the gingival exposure between gender.
