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]

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]

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.

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.
