Curationis , 2012, DOI: 10.4102/curationis.v35i1.45
Abstract: Unplanned teenage pregnancy constitutes an important health problem, whilst contraceptive services are free throughout South Africa and the number of Termination of Pregnancy (TOP) services is increasing. The purpose of this study was to assess the knowledge, attitudes and practices of secondary school girls towards contraception in Thulamela Municipality of Limpopo Province, South Africa. A quantitative descriptive study design was used and respondents were selected by convenience sampling from a population of secondary school girls, the sample consisting of 273 girls in Grades 10–12. A self-administered questionnaire was used to collect data and analysed by computing frequencies and percentages using the Statistical Package for Social Sciences. Findings showed that respondents were aware of different contraceptive methods that can prevent pregnancy. However, most did not have knowledge of the emergency contraceptive, intra-uterine device and female condom. Pressure from male partners, fear of parental reaction to the use of contraceptives, reluctance to use contraceptives, poor contraceptive education and lack of counselling were seen as the main causes of ineffective contraceptive use and non-utilisation. Possible modalities of intervention deal with providing contraceptive counselling and care to empower these school girls to make informed choices on reproductive health.

Abstract: The aim of the study was to determine the factors that influence the uptake of contraception services by adolescents in the Vhembe district of Limpopo Province, South Africa. A qualitative research method which is explorative, descriptive and contextual in nature was used to investigate the phenomenon from the adolescents’ perspective. The target population comprised of adolescents residing in one of the six villages of Vhembe District. Data was collected through six focus group discussions until data saturation was achieved. Data was analysed using an open coding method. The findings revealed that adolescents are aware of the availability of contraceptive services. However, they lack a comprehensive knowledge about contraception and contraceptives, which led to negative attitudes towards using the services. Cultural health beliefs and attitudes were also identified as a barrier to the uptake and use of contraceptives. Recommendations were made on interventions to increase the uptake of contraception services amongst adolescents.

Tuberculosis (TB) is a disease which is caused by a relatively large, non-motile, rod-shaped pathogen called Mycobacterium tuberculosis. TB is a major cause of illness and death worldwide, especially in Asia and Africa. Despite the fact that TB is a curable illness, the tragedy is that TB remains the biggest killer in the world as a single pathogen. The purpose of this study was to describe the support needs of nurses caring for TB patients at Tshilidzini Hospital in Limpopo Province, South Africa. Qualitative, exploratory and descriptive designs were used. Purposive sampling method was used to select the participants. The personal support needs of six nurses caring for TB patients at Tshilidzini hospital were explored, and it was guided by data saturation. Data was collected through in-depth individual interviews, field notes were taken and data audio-recorded. Data was analysed using Colaizzi’s (1978) method of data analysis. Trustworthiness was ensured and ethical considerations were observed.The research findings revealed two major themes from the raw data: support structure available in the hospital and support needs for the nurses.The findings of this study revealed that nurses are in need of special support from the management. Therefore there is an urgent need to address this problem by the Department of Health, Hospital Executive Managers and Nursing Service Manager.

Abstract: There is a growing need to find the most appropriate and effective treatment options for a variety of painful syndromes, including conditions affecting the gastrointestinal tract, for treating both veterinary and human patients. The most successful regimen may come through integrated therapies including combining current and novel western drugs with acupuncture and botanical therapies or their derivatives. There is an extensive history and use of plants in African traditional medicine. In this review, we have highlighted botanical remedies used for treatment of pain, diarrheas and inflammation in traditional veterinary and human health care in Africa. These preparations are promising sources of new compounds comprised of flavonoids, bioflavanones, xanthones, terpenoids, sterols and glycosides as well as compound formulas and supplements for future use in multimodal treatment approaches to chronic pain, gastrointestinal disorders and inflammation. The advancement of plant therapies and their derivative compounds will require the identification and validation of compounds having specific anti-nociceptive neuromodulatory and/or anti-inflammatory effects. In particular, there is need for the identification of the presence of compounds that affect purinergic, GABA, glutamate, TRP, opioid and cannabinoid receptors, serotonergic and chloride channel systems through bioactivity-guided, high-throughput screening and biotesting. This will create new frontiers for obtaining novel compounds and herbal supplements to relieve pain and gastrointestinal disorders, and suppress inflammation.

Abstract: The study evaluated the Implementation of Undergraduate Entrepreneurship Curriculum in Federal Universities in North Central Geo-Political Zone, Nigeria. The study was aimed at finding out the level of the implementation of the GST entrepreneurship education in federal universities in Nigeria and how it has equipped the undergraduate students with the necessary entrepreneurship skills that would enable them?topractice after graduation. Four research questions and two hypotheses were raised for the study. A cross-sectional survey research design was used for the study. The population of the study constituted of seven federal universities in the study area 14 directors, 49 GST lecturers and 25,087 final year (400 levels) undergraduate students. The sample size of the study consisted of five federal universities, 10 Directors (including five GST Directors & five Entrepreneurship Directors), 29 GST lecturers and 1826?final year (400 levels)?undergraduate students using multi-stage sampling technique. The instruments for data collection were structured Undergraduate General Studies Entrepreneurship Curriculum Implementation Questionnaires (UGSECIQ) which were sub-divided into three sections for:?directors, lecturers and students. Content validity was established on the questionnaire by three experts, each from Curriculum Studies, Business Management and Measurement and Evaluation from the University of Jos. A reliability coefficient of 0.890, 0.901 and 0.957 for the directors, lecturers and students’ responses respectively were obtained through Cronbach Alpha. The data obtained for the research questions were analysed using mean, standard deviation and simple percentage while chi-square for independent samples and ANOVA were used for testing the hypotheses using SPSS version 21.0. The results of the findings revealed that the implementation process of the undergraduate GST entrepreneurship education was constrained by inadequate funding to

The main purpose of this study is to obtain the water infiltration parameters of the soils of Michael Okpara University of Agriculture, Umudike. This could be used in simulating infiltration for these soils when designing irrigation projects, thereby saving time and cost of field measurement. Field measurements of infiltration were first made using a double ring infiltrometer. The test lasted for 180 mins in each location. Infiltration values ranged from 0.03 cm/min to 0.1 cm/min. The highest value was obtained in the Forest Block. Kostiakov’s infiltration model was then applied on the field data in order to determine the soils’ infiltration parameters and equations. The model empirical constants or parameters obtained were “m” and “n”. For “m” the values were: 0.53 for the soil of Forest Block, 0.42 for Poultry block, 0.50 for P.G. block, 0.41 for the soils of Staff School and Guest House. The corresponding “n” values were: 1.37, 1.12, 0.37, 1.79, and 1.38. Infiltration equations: 0.4It1.38, 0.4lt1.79, 0.42t1.12, and 0.53t1.37 were determined for the locations. These were used to simulate data which were evaluated by comparing them with the field data. The two data sets showed closed relationships. This implied that the model could be used to simulate water infiltration during irrigation projects in the farms of Michael Okpara University of Agriculture, Umudike.

Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.23014
Abstract: This study determined the effects of kolaviron on the histology of organs of the hypothalamic-pi- tuitary-gonadal axis, mainly the hypothalamus, pituitary and testis. The aim was to ascertain if its consumption has deleterious effects on these organs. Thirty six adult Wistar rats divided into six groups of six animals each were used and kolaviron administered at 100, 200, 400 and 800 mg/kg body weight. The results showed that gross cellular depletion and desquamation of cells of testis significantly reduced number of cells in the hypothalamus and pituitary (P < 0.05). It significantly reduced the relative brain weight (P < 0.05). These findings suggest that kolaviron can alter the histology of the axis which may impair its reproductive function.
A Multi-Objective Obnoxious Facility Location Modelon a Plane  [PDF]
U. K. Bhattacharya
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.12006
Abstract: In this paper a Vertex Covering Obnoxious Facility Location model on a Plane has been designed with a combination of three interacting criteria as follows: 1) Minimize the overall importance of the various exist-ing facility points; 2) Maximize the minimum distance from the facility to be located to the existing facility points; 3) Maximize the number of existing facility points covered. Area restriction concept has been incor-porated so that the facility to be located should be within certain restricted area. The model developed here is a class of maximal covering problem, that is covering maximum number of points where the facility is within the upper bounds of the corresponding mth feasible region Two types of compromise solution methods have been designed to get a satisfactory solution of the multi-objective problem. A transformed non- linear programming algorithm has been designed for the proposed non-linear model. Rectilinear dis-tance norm has been considered as the distance measure as it is more appropriate to various realistic situa-tions. A numerical example has been presented to illustrate the solution algorithm.

World Journal of AIDS (WJA) , 2011, DOI: 10.4236/wja.2011.14019
Abstract: We attempted to study the role of HLA HLA-A, B, DRB1 and DQB1 in HIV-1 patient’s co infected with pulmonary tuberculosis (PTB). A total of 102 HIV-1 + patients co-infected with pulmonary tuberculosis and 200 healthy controls were included in HLA analysis. HLA-A*, HLA-B* HLA-DRB1* and DQB1* typing was done molecularly by PCR- SSOP (Polymerase Chain reaction-Sequence Specific Oligonucleotide Probing) method using kit (Dynal Kit – Invitrogen). The frequencies of the HLA-A, B HLA-DRB,1 and DQB1 alleles were determined using standard software. The HLA alleles identified among HIV + ve/PTB + ve co-infected patients as compared with healthy controls showed a significantly increased frequency of HLA-B*08:01:01 in HIV + ve/PTB + ve co-infected patients when compared with healthy controls (p = 0.011, OR 3.335, 95% CI 1.35-8.18), Likewise HLA-DQB1*03:01:03 was significantly increased in HIV + ve/PTB + ve co-infected patients as against healthy controls (p < 0.0001, OR 107.5, 95% CI 6.195 - 1865.3). Similarly HLA-DQB*06:01:02 allele frequency was observed in HIV + ve/PTB + ve co-infected patients as against healthy controls (p = 0.003, OR 4.808, 95% CI 1.72-13.39), HLA-DQB1*03:01:01 (p = 0.045, OR 0.219, 95% CI 0.051 - 0.940), HLA-DQB1*06:01:01:01 (p = 0.012, OR 0.334, 95% CI 0.145 - 0.770), alleles in HIV + ve/PTB + ve co-infected patients when compared with healthy controls. We can be concluded that different HLA alleles may render susceptibility or protection to in different ethnic population.
Unsteady Incompressible Flow of a Generalised Oldroyed-B Fluid between Two Infinite Parallel Plates  [PDF]
D. Bose, U. Basu
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.32012

This paper presents a study of visco-elastic flow of an incompressible generalized Oldroyd-B fluid between two infinite parallel plates in which the constitutive equation involves fractional order time derivative. The solutions of field equations are being obtained for the motion of the said fluid between two parallel plates where the lower plate starts to move with steady velocity and the upper plate remains fixed in the first problem and the upper plate oscillates with constant frequency and the other being at rest in the second problem. The exact solutions for the velocity field are obtained by using the Laplace transform and finite Fourier Sine transform technique in terms of Mittag Leffler and generalised functions. The analytical expression for the velocity fields are derived and the effect of fractional parameters upon the velocity field is depicted graphically.
