An Adaptive Method using the L-Weno Reconstruction
(International Journal of Engineering Applied Sciences and Technology, 2021-10) Mrumun C. Soomiyol; Terhemen Aboiyar; Nathaniel M Kamoh
In this work, an adaptive formulation of the Legendre - Weighted Essentially Non-Oscillatory (L-WENO) method is used to solve some problems of two-dimensional linear conservation laws on unstructured triangular mesh. The mesh adaptivity is used to improve the performance of the method. Although the results with the L-WENO method gets better as the mesh is refined, the mesh adaptation algorithm was able to improve the quality of the numerical approximation and reduce computational cost by refining and coarsening the computational mesh based on some specified criteria.

Introduction: Malnutrition remains a public health problem in developing countries like Nigeria. Understanding the factors associated with malnutrition is important in tackling the problem.
Objective: The aim of this study was to determine the prevalence of malnutrition and associated factors among under- five children in Borgu Local government area of Niger state, Nigeria.
Material and Methods: A descriptive design was adopted. The study involved 250 children drawn using multi-stage sampling. Data was collected using questionnaire, weighing scale and a
length board. Data was analyzed using chi-squared and descriptive statistics. Stunting, underweight and wasting were determine using the WHO child growth standards.
Result: Findings indicate that prevalence of stunting, wasting and underweight was 47.6%, 8.8% and 25.6% respectively. About 18% were diagnosed with various forms of protein energy malnutrition and is most common among male children (23.2%), younger children (31.8%) (Between 0-11 months) and children of mothers with no formal education (25.2%). Marasmus was the most common form of protein energy malnutrition (63.6%).
Conclusion: Malnutrition is a problem in this setting. Age of child, gender, and maternal educational status have influence on malnutrition.
Pilot Experience with Infrared Photocoagulation As an Office Based Procedure for the Treatment of Hemorrhoids.
(IOSR Journal of Dental and Medical Sciences, 2016-05) Ale A. F; Achinge G. I; Peter S. D; Shitta A. H; Isichei M. W; Misauno M. A
There are many minimally invasive modalities in use for the treatment of hemorrhoids, most of which are unavailable in our setting. This study sought to describe our recent experience with infrared photocoagulation with a view to stressing it's suitability as an office based procedure for treating hemorrhoids. A prospective study of consecutive patients presenting with symptomatic hemorrhoids was conducted over a 3 year period. 21 (22.3%) patients had grade 1 hemorrhoid, 53 (56.4%) had grade 2 and 20 (21.3%) had grade 3 hemorrhoids. All 20 patients with grade 3 hemorrhoids at re-assessment after 2 weeks, the grade had changed to 2. 53 (56.4%) patients had 2 sessions of treatment at 2 weekly interval, while 41 (43.6%) patients had a single session of treatment to cure symptoms. 60 (63.8%) patients had minor post procedure hemorrhage, 14 (14.9%) had mild post procedure pain, 4 (4.3%) had recurrence of symptoms and were treated via open hemorrhoidectomy, while 16 (17.0%) had no procedure related complication. Infrared photocoagulation is an effective, safe and well tolerated procedure for the outpatient treatment of hemorrhoids and may be used to downstage grade 3 hemorrhoids.
Performance Expectancy as a Determinant of Use of Open Access Resources by Lecturers in University Of Ibadan, Nigeria
(International Journal of Academic Library and Information Science, 2017-03) Oluseun Taiwo Akanni; Airen Edale Adetimirin
The research work examined the open access resources as a major source of information resources available to lecturers. Open access provides information resources to lecturers at no cost. Notable among the open access resources are Institutional Repository, Open access databases, open access journals, Author’s personal archives and open text books. Objective of this study was to examine performance expectancy, as a factor affecting the use of open access resources by lecturers in University of Ibadan. The design adopted for the study was the descriptive research and population comprised lecturers from University of Ibadan. Random sampling was used to select 174 as sample size. Questionnaire for Lecturers was used as the research instrument. The analysis was done using descriptive statistics such as frequencies and percentages, while inferential statistics such as the Pearson product moment correlation and regression analysis
was used to test hypothesis at 0.05 level of significance. Majority of the lecturers (77.1%) used open access resources to publish articles in the open access medium and also refer their students for assignment completion. Open access resources were useful to most of the lecturers (76.3%): of relative advantage and very relevant to the academic activities. However the study also revealed that Performance expectancy is a strong determinant of use of open access resources as result showed there was a significant positive correlation between performance expectancy and use of open access resources by lecturers (r= .867**; n = 152; p <0.05)by lecturers. In conclusion, performance expectancy is a strong determinant of use of open access resources by lecturers.
HIGH ORDER A-STABLE BLOCK ETR2s AND THEIR APPLICATION TO SYSTEM OF FIRST ORDER ODES
(Leena and Luna International, Chikusei, Japan, 2014) Awari, Y.S.; Garba, E.J.D.; Kumleng, G.M
An eighth order block Extended Trapezoidal Rule of Second kind (ETR2s) is presented for the numerical integration of stiff system of first-order ordinary differential equations. In the derivation process, we adopt the power series approach which leads to a system of equations that would be solved simultaneously in block form to generate approximate solution for the differential equations. The stability properties of the method are also presented. Some test, reported to emphasize pros and cons of the method.
