Abstract: Dialogue with teenagers about sexual health is of global concern, as it is found mostly to be minimal, if not absent. This limitation is influenced by the cultural values, beliefs and norms of teenagers. To a great extent, culture influences which and how sexual health issues can be discussed between teenagers and adults. The purpose of this study was to explore and describe teenagers’ experiences of sexual health dialogue in the rural areas of the Vhembe district in Limpopo province, South Africa. A qualitative, explorative, descriptive and contextual research approach was used. Data were collected by means of in-depth, individual interviews and focus-group discussions. A purposive sampling method was used to select the 57 participating teenagers, based on criteria that were set. The findings of the study indicated that there was minimal dialogue between adults and teenagers about sexual health. Most teenagers reported that they learned about issues related to sexual health from friends, the media, initiation schools and relatives who, most often, were aunts. It was also noted with concern that the teenagers always equated sexual health to the act of intercourse and that no attention was paid to other aspects of sexual health. Recommendations to improve the current situation were made. Opsomming Dialoog met tienerjariges rakende seksuele gesondheid is ’n wêreldwye probleem omdat daar gevind is dat dit meestal minimaal is of glad nie plaasvind nie. Hierdie beperking word be nvloed deur die tienerjariges se kulturele waardes, oortuigings en norme. Kultuur be nvloed in ’n groot mate watter seksuele gesondheidsake tussen tienerjariges en volwassenes bespreek kan word, en hoe dit gedoen kan word. Die doel van hierdie studie was om tienerjariges se ondervindings van seksuele gesondheidsdialoog in die landelike gebiede van die Vhembedistrik in die Limpopo-provinsie van Suid-Afrika te ondersoek en te bespreek. ’n Kwalitatiewe,ondersoekende, beskrywende en kontekstuele navorsingsbenadering is gevolg.Data is versamel deur middel van grondige individuele onderhoude en fokusgroep-besprekings.’n Doelbewuste steekproefmetode is gebruik om die 57 deelnemende tienerjariges op grond van bepaalde kriteria te selekteer.Die bevindings van die studie het aangedui dat daar minimale dialoog oor seksuele gesondheid tussen tienerjariges en volwassenes is. Die meeste tienerjariges het gerapporteer dat hulle by vriende, die media, inisiasieskole en familielede, meestal ’n tante, van seksuele gesondheid geleer het. Daar is met kommer opgemerk dat tienerjariges seksuele gesondheid
Municipal Wastewater Effluents as a Source of Listerial Pathogens in the Aquatic Milieu of the Eastern Cape Province of South Africa: A Concern of Public Health Importance

International Journal of Environmental Research and Public Health , 2010, DOI: 10.3390/ijerph7052376
Abstract: We evaluated the effluent quality of an urban wastewater treatment facility in South Africa and its impact on the receiving watershed for a period of 12 months. The prevalence and antimicrobial susceptibility of potential Listeria pathogens ( L. ivanovii and L. innocua) and the physicochemical quality of the treated wastewater effluent was assessed, with a view to ascertain the potential health and environmental hazards of the discharged effluent. Total listerial density varied between 2.9 × 10 0 and 1.2 × 10 5 cfu/mL; free living Listeria species were more prevalent (84%), compared to Listeria species attached to planktons (59–75%). The treated effluent quality fell short of recommended standards for turbidity, dissolved oxygen, chemical oxygen demand, nitrite, phosphate and Listeria density; while pH, temperature, total dissolved solids and nitrate contents were compliant with target quality limits after treatment. The Listeria isolates (23) were sensitive to three (15%) of the 20 test antibiotics, and showed varying (4.5–91%) levels of resistance to 17 antibiotics. Of seven resistance gene markers assayed, only sulII genes were detected in five (22%) Listeria strains. The study demonstrates a potential negative impact of the wastewater effluent on the receiving environment and suggests a serious public health implication for those who depend on the receiving watershed for drinking and other purposes.
Nigeria’s Niger Delta: Understanding the Complex Drivers of Violent Oil-related Conflict

Africa Development , 2009,
Abstract: This paper explores the complex roots and dimensions of the Niger Delta conflict which has escalated from ethnic minority protests against the federal Nigerian State-Oil Multinationals’ alliance in the 1990’s to the current insurgency that has attracted worldwide attention. It also raises some conceptual issues drawn from ‘snapshots’ taken from various perspectives in grappling with the complex roots of the oilrelated conflict in the paradoxically oil-rich but impoverished region as an important step in a nuanced reading of the local, national and international ramifications of the conflict and its implications for Nigeria’s development. The conflict is then located both in the struggle of ethnic minority groups for local autonomy and the control of their natural resources (including oil), and the contradictions spawned by the transnational production of oil in the region. The transition from resistance – as-protest – to insurgency, as represented by attacks on state and oil company targets by the Movement for the Emancipation of the Niger Delta (MEND), is also critically analyzed.
Identification of Soil Management Factors from Spatially Variable Soil Properties of Coastal Plain Sands in Southeastern Nigeria  [PDF]

Open Journal of Soil Science (OJSS) , 2011, DOI: 10.4236/ojss.2011.12004
Abstract: Variability in soil properties is a critical element across wide areas of researches especially in several aspects of agriculture and environment including sewage disposal and global climate change. Particle size fraction (sand, silt, and clay), effective cation exchange capacity, base saturation, pH, organic carbon, total nitrogen, carbon nitrogen ratio, available phosphorus, exchangeable bases (calcium, magnesium, sodium, potassium) and acidity are frequently used in agriculture for soil management. The objective of this study therefore was to identify soil management factors from these set of 15 soil properties and spatial distribution of representative soil management properties. The study was carried out in the University of Uyo Teaching and Research Farm measuring 8.19 hectares in University of Uyo Annex, Uyo in Akwa Ibom State of Nigeria. Nine and ten traverses were made horizontally and vertically respectively at 40 meters intervals. A total of 58 soil samples were collected at 0 - 15 cm depth on the grid nodes of the traverses. Particle size distributions, exchangeable bases and acidity, effective cation exchange capacity (ECEC), available phosphorus (avail. P), base saturation (BS), organic carbon, total nitrogen, carbon nitrogen ratio (CNR) and pH of the samples were determined in the laboratory. Coefficient of variation indicated that 26.6% of the soil properties (sand content, pH, CNR and sodium) were least variable, 40.1% comprising silt, clay contents, ECEC, base saturation, phosphorus and magnesium were moderately. Whereas 33.3% of the soil properties comprising clay content, organic carbon, total nitrogen, exchangeable Ca, K and acidity (i.e.) were highly variable. There were significant correlation (p < 0.05) in 26.6% of the soil properties, the strongest negative significant (p < 0.01) correlations were between sand and clay (r = –0.85), exchangeable acidity and base saturation (r = –0.85), whereas the strongest positive significant correlations were between ECEC and Ca (r = 0.80), Ca and BS (r = 0.74), organic carbon and total nitrogen (r = 0.80). Principal component analysis indicated the existence of six factors including mineralogical or weathering, soil organic matter, cation exchange activity, soil texture, and dispersion and soil phosphorus based on either management or pedological considerations. Semivariance statistics showed that sand and clay contents, ECEC, BS and total N were moderately (≥25.7% ≤47.3%), while silt content, pH, organic carbon, CNR, avail. P, exchangeable Ca, Mg, Na and acidity (≥0.18% ≤22.8%) were

Abstract: HIV and AIDS incidence among infants in South Africa is on the increase.The uptake of prevention of motherto- child transmission (PMTCT) interventions is often said to be dependent on the beliefs and educational needs of those requiring PMTCT services.This study therefore sought to examine the effect of clinic-based health education interventions (HEI) on behavioural intention of PMTCT among 300 pregnant women from 4 primary health care clinics in Tshilidzini Hospital catchments area, South Africa. An interview schedule was used to obtain information regarding participants' demographic characteristics, level of exposure to clinic-based HEI, salient beliefs and behavioural intention on PMTCT.The major findings included that approximately 85% of the participants had heard of PMTCT.There was very little association between frequency of antenatal clinic (ANC) visits and level of exposure to PMTCT information. Condom use had the lowest set of salient belief scores. Control belief was the most common belief contributing to behavioural intention. Generally, the association between PMTCT salient beliefs and behavioural intention was weak. Clinic-based HEI had an impact on behavioural intention of HIV testing, normative belief of regular ANC visit and nevirapine use.The vital contribution of alternative PMTCT information sources such as the radio and television was observed. Enhancing initiatives that empower women, and a better coordination of the existing HEI through better implementation of health education strategy may strengthen the prevailing moderate PMTCT intention in the area investigated.

International Journal of Mathematics and Mathematical Sciences , 1978, DOI: 10.1155/s0161171278000204
Abstract: In [1] E. L. Reiss obtained a multivariable expansion of the problem L[y] ¢ ‰ y ¢ € 3+2 μy ¢ € 2+y=0, t>0;y(0; μ)=0, y ¢ € 2(0, μ)=1 by means of a technique which does not employ the traditional method of using a secularity condition in obtaining higher order approximations. In this paper Reiss' technique is formalized and new results are established.
Left Ventricular and Coronary Air Embolism Complicating a Routine CT-Guided Cavitating Lung Mass Biopsy: A Case Report

Research Journal of Medical Sciences , 2012, DOI: 10.3923/rjmsci.2010.248.251
Abstract: Air embolism is an extremely rare complication of image guided trans-thoracic percutaneous lung biopsy whatever the modality or technique employed. Air embolism in the coronary arteries is an even rarer form and is scarcely reported in British medical literature. We present a case of coronary artery embolism following percutaneous trans-thoracic lung biopsy in a 70 years old female and highlight the need for both the interventional radiologist and the referring physician to be aware of this potentially risky complication. An immediate post-biopsy CT is usually adequate to make the diagnosis and is therefore recommended for patients manifesting vaso-vagal syncope and those with a previous history of myocardial infarction.

Abstract: Model for predicting the quantity of water evaporated during the primary-stage processing of a bioceramic material sourced from kaolin has been derived. The model; E = Exp[0.3424(LogT)2.439] shows that the quantity of evaporated water during the drying process is dependent on the drying temperature, the evaporating surface being constant. It was found that the validity of the model is rooted on the expression (Logβ x lnE)N= LogT where both sides of the expression are correspondingly approximately equal to 2. The respective deviation of the model-predicted quantity of evaporated water from the corresponding experimental value was found to be less than 19% which is quite within the acceptable deviation range of experimental results, hence depicting the usefulness of the model.

Abstract: Background: Tuberculosis (TB) is a specific infectious disease caused by mycobacterium tuberculosis while acquired immune deficiency syndrome (AIDS) is a fatal illness caused by human immunodeficiency virus (HIV). Both of them constitute the main burden of infectious public health disease in many parts of the world, particularly in resource limited countries like Nigeria. This study sets out to describe TB/HIV co-infected patients accessing care at the DOTS clinic in a tertiary hospital in South-Eastern Nigeria. Methods: This study was conducted retrospectively at the DOTS clinic of NAUTH Nnewi. A structured proforma was used to extract specific characteristics of TB/HIV co-infected patients who received TB treatment for the period of 1st January 2013 to 31st December 2013. The collected data were analyzed with SPSS version 20. Results: Ninety eight patients (40.6%) were TB/HIV co-infected, out of the two hundred and forty one patients treated for tuberculosis in the DOTS clinic during the period under review. These were the findings among the TB/HIV co-infected patients: there were more females (51%) than males (49%); the commonest age group affected was the group 30 - 39 years (34.7%); majority of the patients (91.8%) had pulmonary TB as against extrapulmonary TB (8.2%) and most of the patients had negative sputum AFB result (43.9%) as against those with positive result (36.7%). Conclusion: This study demonstrated some important characteristics of TB/HIV co-infected patients. Such knowledge if taken into consideration in both the tuberculosis control and HIV control programs will improve the outcomes of the programs.
