Abstract: Healthy ageing is a lifelong process optimizing opportunities for improving and preserving health and physical, social and mental wellness, independence, quality of life and enhancing successful life-course transition. In Sub-Saharan Africa, it is estimated that the number of elderly persons will rise from about 37.1 million in 2005 to 155.4 million in 2050. The elderly population in Nigeria is estimated at 4 percent and is expected to triple by the year 2020. The increasing number of the older population will increase the burden on the health resources. The objective of this study was to evaluate the determinants of healthy ageing among rural elderly in northern Nigeria in order to promote those that have positive correlation with healthy aging. A cross sectional descriptive study was conducted among 1600 rural elderly aged ≥60 years using interviewer administered semi-structured questionnaire between June and July, 2011. Majority (53.8%) are 60 - 64 years, 24.6% >69 years, 72.4% are males while most are Muslims (85.6%) and 81. 4% are still married. Most are farmers (48.9%) while 73.6% have no formal education. 85.3% earn less than $100 monthly while 47.6% have no income. 93.5% do not take alcohol, 92.1% do not smoke and 89.8% are physically active. 83.1% have normal blood pressure (on examination), 88.3% normal blood glucose level (on examination). Diet, no smoking, high physical activity and adequate sleep are positively correlated with healthy aging (p < 0.05). Good health practices and family support should be sustained while special care for the aged should be established by the government.
Operationalising Quality Assurance Processes in Tanzanian Higher Education: Academics’ Perceptions from Selected Private Universities  [PDF]

Abstract: The purpose of this research was to examine the extent of operationalization of quality assurance processes in Tanzanian Private Universities (PRUs). A descriptive survey design informed by a mixed research approach was employed to guide this research. Purposive and stratified random sampling procedures were employed to select a sample of one hundred and ninety-five (N = 195) participants in the study who comprised of 191 academics, and 4 quality assurance officials from four private universities. Questionnaires and face-to-face interviews were used for data collection. The findings indicated that QA processes such as institutional self-assessment and external examinations were to a large extent conducted by PRUs. Unlike these findings, internal quality audits and tracer studies were not adequately carried out. Conclusively, the non-regular practice of these processes remains the main challenge in most of the surveyed Tanzanian PRUs because they are stipulated in the institutional policy documents without a will to adequately implement them.

Abstract:

Cervical cancer is the leading cancer-related cause of death among women in Nigeria. An estimated 70,700 new cases occur each year, representing one quarter of all female cancers in sub Saharan Africa. The magnitude of the problem has been under recognised and under prioritised compared with the competing health priorities of infectious diseases such as HIV/ AIDS, tuberculosis and malaria. Studies in the United States and Nigeria have indicated that the disease has the highest incidence among the lowest socio-economic groups especially residing in rural areas. The peak age for the disease has been shown to be within 35-45 years age group. Knowledge of the risk factors of the disease is deemed important in its early detection and prevention. The objective of this study was to assess the knowledge, attitude and practice of rural women with cancer of the cervix. A cross sectional descriptive study was conducted among 1600 rural women aged 15-55 years (randomly selected from 28 villages) who were interviewed using a structured questionnaire between April and June, 2010. The majority (82.2%) were married before the age of 20 years and 19.3% before 15 years, 40% in polygamous union, 22.6% have had 2 or more sexual partners, 71.3% were primi and grand multiparous, 7.5% have had previous treatment for STIs and 10.1% were on various types of contraceptive. 454 (28.4%) have heard of Ca cervix, 358 (22.4%) knew the location of the cervix. 2.3% had Pap smear test of which 72.6% were within 2 years. The majority (89.9%) will avail themselves for screening.

Practice points: Corporate response to the HIV/AIDS epidemic in uganda – time for a paradigm shift?
Samson Kirondea, John Lukwagob
African Health Sciences , 2002,
Abstract: The HIV/AIDS epidemic is likely to remain the pre-eminent global health concern for the foreseeable future. In Uganda, while significant progress has been made by the government over the past decade in bringing down the rate of new infections, the HIV/AIDS burden in the country remains huge and vigilant efforts must be continued if this burden is to further decrease. Traditionally the government, supported by its international partners as well as local non-government organizations and the community has borne the brunt of the costs of containing the epidemic in Uganda. While the corporate sector in the country has financially contributed towards the costs of some of the interventions that are currently in place to combat the HIV epidemic, there is largely a paucity of sustained and systematic corporate leadership in providing comprehensive HIV/AIDS programmes for their employees. A survey done by the s reveals that most programmes undertaken in the private sector are of limited scope. We argue that there is more the corporate sector can do to more equitably share the HIV/AIDS burden, without necessarily jeopardizing its primary role – namely to maximize returns to shareholders. This paper proposes a conceptual framework of how companies can approach the issue of HIV/AIDS within their workforce and suggests that providing more comprehensive interventions may in some instances result in substantial cost savings through the prevention or at least delay of HIV/AIDS related consequences such as: frequent absences from work, erosion of company skills and knowledge through key employee deaths, and the costs of hiring and training replacements etc. This ultimately could result in positive financial returns to those companies that choose to pursue work place led HIV/AIDS control and prevention programmes.

Abstract: This paper argues that effective public service delivery is fundamental to socio-economic transformation. It emphases the significance of civil registration and vital statistics (CRVS) in planning and management of public service and administration in Africa but indicates that many national statistics offices and institutions in Africa are weak and their data are less dependable and continually impact negatively the public sector planning and management. The authors contends that members states of the African Union should prioritize strengthening their national statistics offices, domesticate and implement the following normative and other related policy frameworks to overcome the above challenges in Africa: the African charter on statistics and strategy for the harmonization of statistics in Africa, the Africa Programme on Accelerated Improvement of Civil Registration and Vital Statistics (APAI-CRVS), the African Charter on values and principles of public service and administration, the African charter on values and principles of decentralization, local governance and local development etc., the paper highlighted the element of good governance and argued that vital social statistics and civil registration were critical to operationalize these elements. Finally, the paper established the nexus among civil registration and vital statistics, public service delivery and good governance and concluded with specific recommendations on how to strengthen civil registration and vital statistics for effective public sector governance and service delivery in Africa.

Abstract: The optimal matching of a propeller to the hull and the diesel engine of the combine diesel or gas (CODOG) system is a critical design analysis in ship building. In this research work, a controllable Pitch Propeller (CPP) was considered whereby the pitch was varied, but only the extreme pitch set the limit of operation and matching was done with the extreme pitch condition. It considers the performance analysis of the propeller, the hull and the engine both in design and off design conditions. Without propulsion a vessel built cannot move and so choosing the right propeller to match the hull and engine is very vital. The various processes involved in the matching of the propeller to the diesel engine and hull of the vessel are considered, in order to achieve optimal performance of the vessel. A Java program (prop-matching) was developed to facilitate the matching process. The graphs obtained are used to determine the matching point at corresponding speed and power. The thrust and torque developed under different conditions as well as their significance, considering the fact that the propeller is a CPP. The engine response in transient conditions in reaction to the turbo charger was considered, the matching graph of the turbo charger compressor was discussed, and the calculated mass flow rate with various engine speeds and boost pressure were also discussed. This program was further used in matching the propeller to the hull and diesel or gas engines of a F90 frigate. The corresponding propeller rpm and engine power with pitch ratios from the program were similar to those from the design of the frigates. The various thrust and torque coefficients and open water efficiency all correspond to the simulated results of those of the naval frigate.

Samson Ogege,John E. Ezike
International Business Research , 2012, DOI: 10.5539/ibr.v5n8p228
Abstract: This article is centered on the role of the Nigeria capital and economic development. The capital market is primarily established to boast the industrial growth and economic development of Nigeria economy by mobilizing long-term funds and capital formation for investment and productive purposes. Using time series data from 1971-2010 and applying the Engle-Granger and Johansen method of co-integration in a VECM setting estimation technique. The results revealed that in the long run, the Nigerian capital market positively and significantly influence economic development. We therefore recommend that government should put more effort in developing an active new issues market by encouraging more floatation of new issues and create stable environment for business.

X-ray aurora in neutron star magnetospheres

Physics , 2004,
Abstract: In this study we propose a new generic model for QPOs based on oscillation modes of neutron star magnetospheres. We argue that the interaction of the accretion disk with the magnetosphere can excite resonant shear Alfven waves in a region of enhanced density gradients. We demonstrate that depending on the distance of this enhanced density region from the star and the magnetic field strength, the frequency of the field line resonance can range from several Hz (weaker field, farther from star), to approximately kHz frequencies (stronger field, ~ 2-10 star radii from the star). We show that such oscillations are able to significantly modulate inflow of matter from the high density region toward the star surface, and possibly produce the observed X-ray spectrum. In addition, we show that the observed 2:3 frequency ratio of QPOs is a natural result of our model.

Abstract: This study aimed at investigating the influence of different growing conditions in two regions, Timbilil and Kangaita, on the levels of catechins and caffeine. Fresh leaf samples of 60 clones cultivated in both sites were obtained, processed and assayed for levels of caffeine, total and individual catechins using Reverse Phase High Performance Liquid Chromatography (RP-HPLC). The obtained data was subjected to analysis of variance using GENSTAT-C statistical software. Safe for a few clones in the Kangaita site had significantly higher total and individual catechins than those grown in the Timbilil site. A mean epigallocatechin gallate (EGCG) content of 7.9% was observed for Kangaita clones compared to 6.7% in Timbilil. A similar trend was observed for the rest of the individual catechin fractions with a mean epicatechin gallate (ECG) of 3.3% in Kangaita and 2.5% in Timbilil, a mean epigallocatechin (EGC) of 5.2% in Kangaita compared to 5.0% in Timbilil and a mean epicatechin (EC) content of 1.5% in Kangaita compared to 1.4% in Timbilil. Similarly in the total catechins analyses, clones in Kangaita had a mean value of 18.7% compared to 16.2% observed for the Timbilil site clones. However, the Timbilil site clones had significantly high caffeine contents (mean, 4.2%) compared to the Kangaita site clones (mean, 3.9%) although with a few exceptions. Significant interactions (P < 0.05) between clone and region are also observed, suggesting that levels of these biomolecules are bound to differ with the growing region but the extent of variation will vary depending on the clonal genotype. The observed differences in levels of these biologically important biomolecules among the two regions shows the importance of the underlying conditions on the production of tea.
