An Integration of Self Potential, Electromagnetic and Resistivity Profiling Methods in the Search for Sulfide Deposits in Gwoza, Borno State, Nigeria  [PDF]
Okwong Tom Nkereuwem, Solomon Nehemiah Yusuf, Manaja Uba Mijinyawa
International Journal of Geosciences (IJG) , 2012, DOI: 10.4236/ijg.2012.32040
Abstract: The combination of Self Potential (SP), Electromagnetic (EM) and Resistivity profiling methods in Gwoza has resulted in the delineation of conductive zones suspected to be sulfide mineralization in the area. Mineralization potentials of –201 mV on the profile AA’, –250.2 mV on the profile BB’ and –203 mV on the profile CC’ respectively have been observed. Correspondingly, both the vertical coil and the horizontal coil readings of the EM anomalies on the profiles AA’, BB’ and CC’ also show significant negative anomalies across the delineated conductive zones. Three resistivity profiles DD’, EE’ and KK’ have also shown very low resistivity values across the said conductive zones. These conductive zones have been established as sulfide mineralization within faults in this work. The recovery of chalcopyrite samples from a hand-dug well close to the delineated conductive zone of the profile BB’ tends to lend credence to the interpretation in this study.
IT-Based Solutions to the Electoral System in Nigeria
AE Okwong
West African Journal of Industrial and Academic Research , 2012,
Abstract: The purpose of this paper is to discuss the challenges as limitations to the current electoral system in Nigeria’s democracy, proffering possible way forward. The flawed electoral process of the last two Presidential elections equally calls for technology- enabled solutions to this social malaise which could lead to chaos and anarchy if nothing is done to forestall these electoral menace in future elections.. Electoral fraud perpetuated in the cause of political activities including pre-election and post-elections pe riods such as multiple registration, invalid voter’s register, multiple voting, poor organization of electoral process, violence, ballot stuffing and snatching, logistic and administrative constraints. This paper takes critical steps to addressing these numerous elections vices in Nigeria’s electoral system, with the aim to provide a viable option that would ensure credible, fair and genuinely acceptable elections in the country, in the foreseeable future. An IT-driven voting, otherwise known as e-voting has been developed for implementation in this paper.
Effect of Artemether Treatment on Plasma Lipid Profile in Malaria  [PDF]
Nkereuwem Edikpo, Paul Obiekwe Okonkwo, Elias Adikwu
Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.57074
Abstract:

This study was undertaken to assess the effect of artemether treatment on plasma lipid profile in malaria infection. While the importance of lipid to plasmodial infective processes and metabolism is being increasingly appreciated, little is known about the attendant effect of chemotherapy on plasma lipid profile. Thirty patients with uncomplicated malaria were chosen from two secondary health-care facilities in Yobe State, Nigeria with informed consents and ethical clearance. Based on predetermined inclusion criteria patients were given 3.2 mg/kg of artemether with 1.6 mg/kg on subsequent days for a total of five days. This was done after the collection of urine and blood samples for urinalysis, malaria parasite density count and serum lipid analysis. A follow-up was planned seven (7) days from first dose during when clinical assessment and repeat malaria parasite density count and serum lipid analysis were done. Data were analyzed with statistical package for social scientist and Microsoft Excel spread sheet while level of significance at p ≤ 0.05 was calculated using paired t-test. Serum HDL cholesterol concentration recorded a significant decline of 0.13 mmol/L from a pre-treatment mean concentration of 1.17 mmol/L (p < 0.04). Triglyceride, total cholesterol, LDL-cholesterol, VLDL-cholesterol showed increment or reductions that were not significant. The clinical cure rate was 50% and mean percentage reduction in parasitaemia was 52%. A possible explanation for this low cure rate could be resistance, unfavorable pharmacokinetic disposition or lack of full adherence. A trial with complete parasite clearance, possibly using artemisinin-based combinational therapy would provide a more compelling result.

Mental Illness , 2010, DOI: 10.4081/mi.2010.e1
Abstract: A few months from the time of this survey, the nearly completed inpatient psychiatric facility within the Aminu Kano Teaching Hospital’s complex would be ready for admissions. Understanding the health workers’ level of experience of mental illness and their likely behavioural responses towards people with psychiatric illness, therefore, should be a good baseline to understanding their likely reactions towards admitting such patients within a general hospital setting. The study, which used a pre-tested and adapted attribution questionnaire, was pro-spective and cross-sectional. Randomly selected health workers in Aminu Kano Teaching Hospital had their level of familiarity and attributions towards psychiatric patients assessed. The respondents showed a high level of experience with mental illness, with more than 3 in 5 of them having watched movies on mental illness before. More than half of them held positive (favorable) attributions towards persons with mental illness on nine of the ten assessed attribution factors. Almost all held negative (unfavourable) opinion towards intimate relationships with such persons. Attribution factors, “Responsibility, “Anger”, “Dangerousness”, “Fear” and “Segregation” were significantly related to the respondents’ level of education (P less than 0.05). Marital status of the respondents related significantly to “Pity” and “Avoidance” factors (P less than 0.05). Having watched movies on mental illness significantly related to “Responsibility” and “Fear” factors (P less than 0.05). Programs designed to improve the health workers mental health literacy, and increased positive professional contacts with mentally ill persons on treatment, would further enhance their perceived positive attributions towards them.
Tenofovir Renal Toxicity: Evaluation of Cohorts and Clinical Studies—Part One  [PDF]
Adikwu Elias, Ogbuehi Ijeoma, Nkereuwem Jonathan Edikpo, Deo Oputiri, Oru-Bo Precious Geoffrey
Pharmacology & Pharmacy (PP) , 2013, DOI: 10.4236/pp.2013.49092
Abstract:

Tenofovir is one of the most commonly used antiretrovirals in adolescents and adults because of its potency and favorable pharmacokinetic and relative safety toxicological profile. It has been combined successfully with antiretroviral drugs from classes such as protease inhibitors, non-nucleoside reverse transcriptase inhibitors and nucleoside reverse transcriptase inhibitors to achieve virologic suppression in a high percentage of recipients. Despite its therapeutic success, quite a number of cohorts and clinical studies have associated tenofovir with the development of renal toxicity with few studies on the opposing end. This stimulated us to review reported cohorts and clinical studies on tenofovir renal toxicity. In this study it was observed that literature reported incidence of tenofovir renal toxicity falls within the range of 0.7%-17%. Available studies gave different appellations to tenofovir renaltoxicity, which include fanconis syndrome, proximal tubule dysfunction, acute renal failure, chronic renal failure, chronic kidney disease and nephrogenic diabetes insipidus. Markers of renal toxicity (tubulopathy) which include glycosuria, hyperaminoaciduria, proteinuria, hyperphosphaturia, hyperuricosuria, retinol-binding protein, beta2-microglobulinuria, decreased creatinine clearance and

Instructional technology in higher education: A case of selected universities in the Niger Delta

Asia-Pacific Forum on Science Learning and Teaching , 2009,
Abstract: This article examines the effectiveness of instructional technology in higher education institutions in relation to the role and usage of Information Communication Technology (ICT), its effectiveness in faculty teaching and its impact on student learning in universities in the Niger Delta of Nigeria. This study applied the Need Assessment Approach (NAA). A self-designed questionnaire, that employed benchmarks from similar studies conducted in the West, was used to collect data for this study. One hundred and twenty five (n = 125) respondents participated in the study. The results suggest that there are significant relationships between the impact of instructional technology, the usage of instructional technology and students’ academic achievement. An absence of ICT instructional materials, ineffective policy implementation and a lack of other resources (infrastructures) to aid teaching and learning are responsible for short comings in the effective implementation of ICT in education. The study revealed that experience makes it easier to employ and exhibit greater proficiency when using ICT instructional material in the teaching and learning process. The findings and nature of this study bare implications for higher education administrators, faculty and researchers. By design, this research was based on a narrow field of literature and a small sample size. Consequently, it is recommended that further studies are based on a more widespread survey of literature and a larger sample size, which might also involve multiple case studies.
What’s Wrong with Requirements Specification? An Analysis of the Fundamental Failings of Conventional Thinking about Software Requirements, and Some Suggestions for Getting it Right  [PDF]

Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.39096
Abstract: We know many of our IT projects fail and disappoint. The poor state of requirements methods and practice is frequently stated as a factor for IT project failure. In this paper, I discuss what I believe is the fundamental cause: we think like programmers, not engineers and managers. We do not concentrate on value delivery, but instead on functions, on use-cases and on code delivery. Further, management is not taking its responsibility to make things better. In this paper, ten practical key principles are proposed, which aim to improve the quality of requirements specification.
Internal Resource Audit for Strategists—A Proposal  [PDF]
Tom Connor
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.33038
Abstract: It is the purpose of this article to suggest a structured approach to internal resource audit, which, whilst of necessity general-purpose in design, would be capable of adaptation to particular company cases. Consequently this paper does not aim at theory development, but to make a conceptual contribution to the art and practice of management. It will, however, offer some criticism of current theory from a management perspective.
Tensioned Metastable Fluid Detectors in Nuclear Security for Passively Monitoring of Special Nuclear Materials―Part A  [PDF]
Tom Grimes, Rusi Taleyarkhan
World Journal of Nuclear Science and Technology (WJNST) , 2011, DOI: 10.4236/wjnst.2011.13010
Abstract: This paper (constituting Part A) describes the transformational Tensioned Metastable Fluid Detector (TMFD) based method for “passive” detection of Special Nuclear Materials (SNMs) as related to nuclear security. Purdue University is developing novel, multi-purpose tension metastable fluid nuclear particle detectors by which multiple types of nuclear particles can be detected with high (90%+) intrinsic efficiency, spectroscopic capability, directional information, rapid response, large standoff and significant cost-savings compared with state-of-the-art systems. This paper focuses specifically on recent advances in the use of these novel detector systems for neutron spectroscopy. These techniques will then be discussed and evaluated in the context of area monitoring in waste processing applications with a focus on passive monitoring of radioactive source particles from SNMs. The companion paper (Part B) addresses TMFD technology as it pertains to active interrogation.
Pass/Fail Criterion for a Simple Radiation  [PDF]
Tom Burr, Avigdor Gavron
Modern Instrumentation (MI) , 2012, DOI: 10.4236/mi.2012.13004
Abstract: One of the simplest tests of a radiation portal monitor (RPM) is a series of n repeats (a vehicle drive-through) in which the ith repeat records a total number of counts Xi and alarms if Xi ≥ T where T is an alarm threshold. The RPM performance tests we consider use n repeats to estimate the probability p = P(Xi ≥ T). This paper addresses criterion A for testing RPMs, where criterion A is: for specified source strength, we must be at least 95% confident that p ≥ 0.5. To assess criterion A, we consider a distribution-free test and a test relying on assuming the counts Xi have approximately a Poisson distribution. Both test options require tolerance interval construction.
