This work reports an innovative design of tubular solar still with a rectangular basin for water desalination with flowing water and air over the cover. The daily distillate output of the system is increased by lowering the temperature of water flowing over it (top cover cooling arrangement). The fresh water production performance of this new still is observed in Sri Ramakrishna Mission Vidyalaya College of Arts and Science, Coimbatore (11° North, 77° East), India. The water production rate with no cooling flow was 2050. ml/day (410. ml/trough). However, with cooling air flow, production increased to 3050. ml/day, and with cooling water flow, it further increased to 5000. ml/day. Despite the increased cost of the water cooling system, the increased output resulted in the cost of distilled water being cut in roughly half. Diurnal variations of a few important parameters are observed during field experiments such as water temperature, cover temperature, air temperature, ambient temperature and distillate output. © 2012 Elsevier Ltd.

The goal of the green-mobile technology is to attain negligible anthropogenic emissions of carbon dioxide (from the GSM base station generators), which constitute by far the largest part of the emissions of greenhouse gases, thereby making the environment much more friendly and safe. This study established the effect of altitude on the output power of wind turbine generators, and proposed a robust model to account for this effect is proposed for optimal sizing of a wind energy conversion system (WECS) for green-mobile applications. The proposed model implementation using a perfectly fitted polynomial expression derived from the manufacturer's power profile. Adjustment of the observed mean wind speed data to a 75 m lattice tower of a mobile station indicates that the proposed model can be effectively powered by mean wind speed for three different locations (Abuja, Benin City, and Katsina) in Nigeria. Analysis indicates that WECS, with its turbine is placed at an altitude of 100 m, loses approximately 1% of its output power. © 2013 Copyright Taylor & Francis Group, LLC.

The study is prompted by the significant public health impact of continuing rise in the emerging and re-emerging infectious diseases.and to determine the awareness and practice of safety measures in the handling of medical wastes among health workers in a teaching hospital. MATERIALS, SUBJECTS AND METHODS: Stratified sampling technique was used to choose 325 respondents from different professional groups and cadres of health workers and these included medical doctors, nurses/midwives, laboratory workers, ward attendants, porters, cleaners and laundry workers at the University of Ilorin teaching hospital between January and June 2008. Simple random sampling method by balloting was used to select subjects in each group. Data was collected using structured, self administered questionnaires which considered all the variables under study. Data collected were analyzed using Epi-Info computer software program. Three hundred and twenty five (325) questionnaires were administered, out of which 320 were returned giving a response rate of 98.5%. Respondents are nurses 128 (40.0%), doctors 107 (33.4%) and pharmacists 10 (3.1%). Years of work experience ranged from 3 to 27 years with respondents who had working experience between 11 to 15 years constituting over one quarter, 88 (27.5%) while those below 5 years were 8 (2.5'%). Two hundred and ninety eight (93.0%) respondents knew about hospital wastes while 193 (60.3%) only knew about general wastes. Majority of the health workers have appreciable knowledge of collection, minimization and personal risks associated with hospital wastes 299 (93.4%), 302 (94.4%) and 311 (97.2%) respectively. The most common routine safety practice is putting on protective clothing. This study revealed a high level of awareness of hospital wastes among health workers; however, the practice of standard safety measures was low. It is recommended that hospital wastes disposal and management policy be formulated and appropriate committee constituted to monitor compliance with the policy and create awareness among health workers on this policy and its implementation through training and re-training.

BACKGROUND: Adverse cutaneous drug eruptions are dreaded complication of drug use and this is more so when it occurs in the setting of human immune virus (HIV) infection and acquired immune deficiency syndrome (AIDS). AIMS AND OBJECTIVES: This study aims to look at the prevalence of cutaneous drug eruptions in adult Nigerians with HIV/AIDS and find out the etiological agents, outcome, and prognosis of such occurrence in Irrua Specialist Teaching Hospital, Irrua Edo State Nigeria. SUBJECTS AND METHODS: A retrospective study of cutaneous drug eruptions in patients with HIV/AIDS managed in this centre over the past five years (between January 2001 and December 2005 prior to initiation of antiretroviral therapy) was carried out. RESULTS: A total of 900 patients with HIV/AIDS were managed during this period (antiretroviral treatment was not available during this period). Twenty five of these patients (2.8%) not had cutaneous drug eruptions (2.8%). Erythema multiforme major or Steven Johnson Syndrome (SJS)-40% and Toxic epidermal necrolysis (TEN)-20% were the most frequent types of adverse cutaneous drug events found while combination antituberculosis agent of Isoniazid/Thiacethazone (64%) and anti malarial Sulphadoxine/Pyrimethamine (20%) were the notable culprit drugs found to be responsible for these. There was a 20% fatality rate. CONCLUSIONS: Treatment of tuberculosis which is the most common AIDS presenting illness with anti tuberculosis regimen that includes thiacethazone and the ready availability of anti malarials over the counter without prescription are responsible for the findings of this study. Avoiding drugs such as those found to be culprit agents in this study in patients with HIV/AIDS; right prescription practice by health practitioners as well as more intense health education of the public on the hazards of self prescription will all go a long way in minimising the occurrence of these events.

Background: Systematic attention to adverse drug reactions (ADRs) started with the thalidomide disaster in the early 60s of the 20th century. In 1968 ten countries supported a spontaneous reporting system for ADR and collaborated with the WHO pilot research project for international drug monitoring. This survey was conducted to determine the level of awareness of resident doctors about ADRs reporting, the extent of their involvement in pharmacovigilance activities and to build a useful data base that will improve the quality of health care in Nigeria. Setting: This cross-sectional observational survey was conducted in University of Benin Teaching Hospital (UBTH) and Irrua Specialist Teaching Hospital (ISTH), Lagos University Teaching Hospital (LUTH) and Lagos State University Teaching Hospital (LASUTH) in Edo and Lagos states, Nigeria, respectively. Study Design / Methods: A cross-sectional observational survey was used in this study. Total population under survey being 971 residents with the sample size of 350 statistically determined. Results: The survey conducted revealed that 78.1% (258) of the respondents had inadequate knowledge about pharmacovigilance with 71.2% (235) unaware of the yellow forms for ADR reporting distributed by the National Agency for Food and Drug Administration and Control (NAFDAC). The respondents (92.4%) have observed ADRs in the course of their training and practice, yet only 25.5% of cases were reported. The reported cases (7.3%) were to the National Agency for Food and Drug Administration and Control. The study showed a statistically significant difference between the institution of respondents, knowledge and experience about pharmacovigilance (p<0.05). Conclusion: There is marked under-reporting of cases and a low level of awareness about pharmacovigilance among resident doctors in Edo and Lagos states. This may be what obtains in other states in Nigeria. Copyright © 2009 John Wiley & Sons, Ltd.

Impact Assessment and Project Appraisal | Year: 2012

Health impact assessment (HIA) provides useful information on existing health services, their capabilities and the health status of the local communities, which is otherwise often unavailable. In Nigeria, HIA is usually applied to projects and, by exposing existing health inequities in project communities, provides the necessary tool for development proponents to act to provide or improve health services and to implement health promotion activities. Based on HIA experience in Nigeria, this paper highlights the deficiencies in national legislation with regards to HIA/EIA (environmental impact assessment) integration and a number of learning points are discussed. First, a complete health baseline is critical to the understanding of project impacts; analysis must be broad-based, considering existing health determinants. Second, community stakeholders and proponents may modify the implementation of health mitigation measures and should be seen as collaborators in the assessment process. Third, strong HIA recommendations can influence project design. A greater participation of the health sector in EIA is required to enhance HIA utilization. © 2012 Copyright IAIA.

This paper describes an investigation carried out to study the recycling of spent engine oil as a result of indiscriminate disposal of the spent engine oil into the surrounding which has contributed immensely to the level of environmental pollution in our society and nation at large. This paper identify a unique method by which the spent oil is adequately recycled for reuse, the cost of recycling is relatively low compared from its production from crude oil as the numbers of purification stages are reduced. From the research carried out it was discovered that when 25 liters of spent oil was recycled appropriately, 10 liters of lubricating oil was obtained from the process whereas 220 liters of crude oil would be required to produce the same 10 liters of oil. © 2010 Kavala Institute of Technology.

The effect of abattoir effluent on the physical and chemical properties of soils was investigated under natural environment in pot experiment at Ambrose Alli University Teaching and Research farm, Ekpoma, Nigeria. A composite soil sample was used in the experiment. The soil was treated to seven rates of abattoir effluent (viz. 0, 25, 50, 100, 125 and 150 ml/kg soil). The treatments were laid out in randomised complete block design replicated three times. The physical and chemical properties of the soil were determined before pollution and at the end of the experiment, 5 weeks after pollution. Results obtained revealed that abattoir effluent increased pH, available P and micronutrients (Zn, Mn and Fe) significantly in the soil whilst exchangeable cations were reduced significantly when compared to the control. © Springer Science+Business Media B.V. 2010.

The Intergovernmental Panel on Climate Change (IPCC) has predicted global rise in temperature and carbon dioxide is a major greenhouse gas responsible for global warming. The cement industry contributes approximately five per cent of the total CO 2 emitted worldwide. Ewekoro cement Plant, located in Ewekoro, Ogun State was used as a case study to evaluate the results of various modifications on cement plants operation that can impact on the plant CO 2 emissions. An economic model which objective is to highlight the best selection strategy to reduce CO 2 emissions with the least cost was developed using the industry data as part of this paper. The cement Plant achieved a significant result of 23.6 per cent reduction in CO 2 emissions per tonne of cement produced. The results were achieved mainly by applying a progressive approach prioritizing project implementation effort and feasibility. © 2010 Kavala Institute of Technology.

This paper presents an overview of the concept of second law applications to all processes of thermofluid systems. The presentation is motivated by the need for engineers to be familiar with the new concept of exergy and entropy generation minimization, EGM which are used to design industrial production plants or individual components to maximize their energetic efficiency, and to minimize their environmental impact. It is essential for understanding to what extent resource and energy scarcities, nature's capacity to assimilate loss as well as the irreversibility of transformation processes, constrain economic action. With these techniques and computational fluid dynamics, CFD, which is used for the conversion of the differential equations of flow to algebraic equations, designers can use the second law to focus on particular regions where design modifications can be made to improve and optimize thermofluid systems performance. Two case studies of exergy/EGM computations are presented for the design of open cycle simple gas turbine and vapour compression refrigeration. © (2010) Trans Tech Publications, Switzerland.
