Seismic Interpretation Integrated with Rock Physics and Petrophysical Analysis for the Characterization of 'JAY Field,' Niger Delta

2022-01-22T05:47:57+00:00

Reservoir Characterization involves a holistic approach of describing a reservoir by integrating geologic, geophysical, petrophysical and reservoir engineering using all available data for the characterization of the reservoir’s geometric features (including structural and stratigraphic controls) and Petrophysical properties (including porosity, permeability and fluid saturation). The focus is to understand and identify the flow units of the reservoir and predict the inter-well distributions of relevant reservoir properties. JAY field was characterized via Petrophysical analysis, seismic interpretation and modelling, and rock physics analysis. Porosity and permeability models were generated and combined with petrophysical analysis in characterizing the delineated reservoirs. The rock physics cross-plots were used to quality check the results from the seismic and Petrophysical analysis. The structural interpretation of the 3D seismic data of the field revealed anticlinal structures (four-way closure) which is fault assisted and can thus allow hydrocarbon accumulation. Four of the faults are major listric faults that trend in the Northeast Southwest direction. Amongst the remaining fourteen minor faults, five of them are synthetic faults whose sense of displacement is similar to its associated major faults while others are Antithetic faults. Four horizons were established which indicated the top and base of the two reservoirs. The Petrophysical analysis indicated that the reservoirs have good pore interconnectivity (Average ∅

MHD Flow of Fractionalized Jeffrey Fluid with Newtonian Heating and Thermal Radiation Over a Vertical Plate

2022-01-22T04:57:28+00:00

The objective of this paper is to analyze the influence of heat absorption/generation and mass diffusion on magnetohydrodynamics(MHD) Jeffrey fluid flow over a perpendicular plate moving exponentially immersed in a porous media. The Newtonian heating condition are udes for the fluid motion. The impact of thermal radiation is used in the energy equation. The two types of magnetic field have been evaluated. The main purpose of present work is to acquire the analytical solution with the help of Atangana-Baleanu (AB), Caputo, and Caputo-Fabrizio fractional derivatives. We have drawn a graphical comparison between the solutions of these three types of fractional models of jeffery fluid. Graphs of different parameters have been also plotted using MathCad software. Furthermore, comparison among ordinary and fractionalized velocity fields are made to observe the impact of fractional parameter . It is clear from graph that velocity obtained with ordinary derivative is higher than that obtained with fractional derivatives. It is also found that velocity obtained with Atangana-Baleanu (AB) fractional derivative is smaller than that obtained with Caputo and Caputo-Fabrizio fractional derivatives. Therefore, Atangana-Baleanu fractional derivative is the best choice to obtain controlled velocity.

Sensitivity and Heterozygous Balance of Globalfiler IQCTM PCR Amplification and Verifiler PlusTM Kits

2022-01-22T04:33:58+00:00

The Combined DNA Index System (CODIS) core loci was expanded from the existing 13 to 20 STRs, meaning a new kit will needed for many laboratories. A validation study was performed in accordance with SGWDAM guidelines Scientific Working Group on DNA. This main objective of this study was to measure the sensitivity and the heterozygous allele balance of Globalfiler IQC^TM kit and Verifiler Plus^TM kit in order to ensure that the kits would produce reliable profile. DNA samples ranging from 4 ng to 0.016 ng were amplified in 25 ul reaction volume to define the sensitivity and heterozygous balance of two systems. The data suggested that the Verifiler Plus^TM kit is more sensitive than the Globalfiler IQC^TM kit. However, the data of heterozygous balance also show that the Globalfiler IQC^TM kit appeared to be more balanced peak heights than the Verifiler Plus^TM kit. This performance demonstrated that both amplification kit can produce robust and reliable results in forensic DNA identification.

Determinants of Undernutrition among Children under Age 5 in the Puntland State of Somalia

2022-01-22T04:14:32+00:00

The purpose of this study was to investigate the determinants of nutritional status among children under age 5 (0-59 months) in Puntland. Undernutrition is a global challenge, it does not only adversely affect short‐ and long‐term health and economic well‐being of children but it is also a leading contributor to death and disability globally. Undernutrition short-term effects include mortality and morbidity where long-term effects are that the children do not reach their full developmental potential and would have poor cognitive performance, which in turn has consequences on the country’s economic productivity. Nutritional status of the Somali children in Puntland is relatively poor due to many reasons such as low economic conditions of Somali households, lack of food security and severe drought that has affected the country in recent years and among other factors. This study used data from the Puntland Health and Demographic Survey 2020 which was conducted by the Department of Statistics at Puntland Ministry of Planning, Economic Development, and International Cooperation with technical support from UNFPA Somalia. The analysis used stunting, wasting, and underweight as dependent variables, while the independent variables were children, maternal, and household characteristics. Bivariate and multivariate Logistic regression models were performed to analyze the determinants of nutritional status among the children.

The study showed a significant association between children’s nutritional status and most of the explanatory variables under study. Place of residence, gender of household head, wealth index, source of drinking water, source of energy for cooking, toilet facility, mother’s age, marital status, education, breastfeeding, ANC visits, BMI, work status, child’s sex, child’s age, birth order and size at birth have significant associations with children’s nutrition status. The study found that most variables in child, maternal, and household characteristics were significantly associated with stunting and wasting among children under age five. Based on these findings, the research recommends that a multi-sectoral approach is needed to address undernutrition in Puntland state. Combined nutrition programmes from different sectors in line with National Development Plans (NDP) need to be designed to address the underlying causes of acute and chronic malnutrition.

Phytochemical, Pharmacological and Toxicological Aspects of Capparis erythrocarpos Isert.: A Review

2022-01-22T05:19:13+00:00

Capparis erythrocarpos is a shrub plant with a large natural distribution used in traditional medicines to cure various illnesses. The study sought to review and compile all data available on this medicinally important plant, which will help inform scientists and researchers the gap needed to be filled in studying the plant. The present review summarizes information concerning the ethnopharmacology, morphology, phytochemistry, toxicology and biological activities of C. erythrocarpos. Scientific databases such as NCBI/PubMed, Google scholar, Sci finder, Science direct were searched for published article on the plant. The active phytochemicals; flavonoids, alkaloids, terpenoids, phytosterols, glycosides, tannins, coumarins and saponins have been identified from various parts of the plant. Pharmacological and biological studies on the plant have revealed its antimicrobial, analgesic, anti-inflammatory, antipyretic, anti-diabetic and anti-dyslipidemia activities, with no reported toxic effect.

It is recommended that future studies should focus on identification, separation, purification and quantification of the most bioactive constituents of C. erythrocarpos due to the paucity of information in this area.
