Good governance has always been an important issue in global development. Most third world countries have been identified by the World Bank as chronically groaning under the spell of under-development, rooted in corruption and bad leadership. Many ad-hoc solutions embarked upon by various International Organisations have proved insignificant in most African countries. The pseudo-development approaches based on the replication of western mode of development to the developing world have aroused suspicion that the mode of development in the West cannot be used as a basis for engineering growth in other parts of the world, particularly Nigeria. Many studies are conducted in Nigeria to explain how good governance leads to development and poverty alleviation, yet sufficient breakthrough is not achieved. There is need to explore why it is difficult for Nigeria to translate its economic development to enrich its people. This article examines the loopholes in the development priorities of various governments in Nigeria. It is timely based on the recent IMF statistics that Nigeria is now the largest economy in Africa. It examines the impact of development and good governance on poverty alleviation in Nigeria; seeking to explore the potency and place of good governance in poverty alleviation in the largest country in Africa. Relevant literatures were reviewed to closely examine the gap, which ultimately provides rationale for conducting the research. The study, based on the established rapport between good governance, development and poverty, examines the relevance to the Nigeria case. It is therefore premised on the conviction that the three concepts are inevitably intertwined and thus if properly integrated can be employed in studying Nigerian situation and used in the alleviation of poverty. Contribution/ Originality
The primary contribution of this paper is finding that discussions on good governance, rural development and poverty management are relevant to Nigeria as the most recently ascertained ‘the largest economy in Africa’; contributing in the existing literature on good governance, rural development and poverty alleviation as applied mostly on Nigeria.

Research Article
Author(s):
Journal: Journal of Building Construction, Planning and Materials Research
The present paper deals with modified linear regression type ratio estimators for estimation of population mean of the study variable when the Kurtosis, Skewness, population correlation coefficient and quartiles of the auxiliary variable are known. The bias and the mean squared error of the proposed estimators are derived and are compared with that of simple random sampling without replacement (SRSWOR) sample mean, the usual ratio estimator and the existing modified linear regression type ratio estimators. As a result, we have derived the conditions for which the proposed estimators perform better than the other existing estimators. Further the performance of the proposed estimators with that of the existing estimators are assessed for a natural population. From the numerical study it is observed that the proposed modified ratio estimators perform better than the existing estimators. Contribution/ Originality
Dentigerous cyst is an epithelial-lined developmental crater that encloses the crown of an unerupted tooth at the cementoenamel junction. Bilateral or multiple dentigerous cysts are often associated with few syndromes. Even though dentigerous cysts are common developmental cysts, bilateral occurrence of dentigerous cysts are extremely uncommon and to date, only 22 cases have been reported in literature till 2011. In English based language literature review, we only found nine reports of non-syndromic bilateral dentigerous cyst associated with mandibular third molars. The present article report a case of bilateral non-syndromic, dentigerous cysts associated with inverted mandibular third molars in a 25 years old male patient with brief review of literature. Contribution/ Originality
The paper contributes about the rare entity which is associated with various syndromes and systemic disorders, so careful examination and proper diagnosis is useful to rule out various systemic disorders & syndromes Medical Sciences » Journal of Diagnostics » Month: 06-2014 Issue: 1
Anthropometric Parameters as Predictors of Peak Expiratory Flow Rate in Central Indian Children 5-15 Years
The development of pulmonary function and growth of physical parameters are concurrent in children. Hence, measurement of lung function is essential for evaluation of physical development of children and adolescent with respiratory disease. A cross sectional study was conducted on 200 primary, middle and high school children of 5-15 years. Their anthropometric parameters and peak expiratory flow rate (PEFR) were recorded and multiple regression equations for predicting PEFR from anthropometric variables were derived. Highly significant positive correlation (P<0.01) was observed between all the anthropometric and pulmonary parameters. Significantly high R2 values were found when age, height, weight, chest circumference, BSA and arm span were used as independent variables in the regression analysis. Thus, this study establishes reference standards for predicting PEFR in normal healthy children residing in Central India. Contribution/ Originality

Retrospective Study on Outcome of In-Patient Treatment of Severe Acute Malnutrition in Jimma University Specialized Hospital from September 2011-September 2012
Background: Malnutrition often affects young children and contributes to more than 60% of deaths in children in developing countries. Aggressive hospital based management of sever acute malnutrition is recommended to meet the acceptable standards regarding outcome of the treatment. This study aimed to assess the treatment outcome of severely malnourished children treated in Jimma university specialized hospital (JUSH).Methods: Retrospective reviews of charts of severely malnourished children admitted at JUSH from September 2011 to September 2012 were made. In this study, a total of 173 cards were selected using systematic sampling technique. The numbers of discharges cured, defaulted, and average length of stay in days (d) were reviewed. Multivariate logistic regression was applied to identify and control potential confounders. P-value < 0.05 was considered significant.Results: Of 173 cases of malnutrition, 53.2% (92) had kwashiorkor and 30% (52) were Marasmic cases. Of the total, 87% (152) were cured while 5.8% (10) had died. The average length of stay was around 21 days. The study revealed significant association between age distribution and type and outcome of malnutrition. Association is also evident between presence of associated medical illness and duration of stay (p < 0.05).Conclusion and recommendation: In conclusion, the overall recovery, defaulter and mortality rates were within the acceptable range of sphere standards. Thus, the in-patient program was effective. However, more should be done to improve treatment outcome along with duration of stay by working aggressively on management of medical associated problems.

Urban Area - Review of Protective Forest Management
Protective forests are areas, primarily used for wood production in the past, where forests gradually attain different roles based on its purpose and management plan. Forests are significant factors in karst management where over time devastated forest areas have been cultivated with conifers.One of those areas is camp (N 43°55’, E 15°30’) in small coastal city- Pakoštane, where we’ve conducted our research. It is almost a century old Aleppo pine culture which spreads over 25 hectare, on limestone based brown and red soil with more than 45 % stony surface. Holm oak forest is community (Orno – Quercetum ilicis H-ić 1957.) with mostly dense canopy, normal density and no silvicultural work in past few decades. The forest has following structure- number of trees: Aleppo pine 346/ha, Holm oak 261/ha, evergreen deciduous bushes (< 2,5m height) 1047/ha or in total 1654/ha; - basal area: Aleppo pine 26,47 m2/ha, Holm oak 3,23 m2/ha, evergreen deciduous bushes 4,33 m2/ha or in total 34,03 m2/ha. In contrast to normal ecological-management type (EMT) III-L-10 [1] significant differences have been detected. Absence of necessary silvicultural interventions is visible considering relevant indications of present state: average crown transparency “2”, short and thin canopy, great number of deadwood: Aleppo pine 432/ha and Holm oak 148/ha, appearance of fungus fruiting body on 60 trees/ha, construction work mechanical damage of both trunk and root system 140 trees/ha and lastly Aleppo pine tree marking conducted by non-professional forester- resulted in wrong selection of trees that are meant to be fallen in future maintenance period.Natural forest degradation that is taking place in this woodland, due to anthropological influence on stand, unfortunately led the forest of this auto-camp in troublesome state. Contribution/ Originality
This study contributes to urban forestry- arboriculture, as urban park research on protective forests management and user safety in private parks. It contributes in the existing literature on urban park-protective forest, governance and as a current practice review it points out the ongoing problems and malpractice occurring in urban forestry.

Soil Respiration, Microbial Biomass and Ratios (Metabolic Quotient and Mbc/Toc) As Quality Soil Indicators in Burnt and Unburnt Aleppo Pine Forest Soils
Wildfires affecting forest ecosystems and post-fire silvicultural treatments may cause relevant changes in soil properties. Soil plays an important role in the fertility and stability of the forest ecosystem [1] as it highlights the microorganisms that accomplish reactions to release soil nutrients for vegetation development [2]. Wildfires and post-fire silvicultural treatments may cause relevant changes in forest and soil properties [3, 4]. Fire may alter physical-chemical soil properties (i.e., soil organic matter content and its structure, hydrophobicity, pH and nutrient cycles) [5], microbiological and biochemical soil properties (i.e., microbial biomass, microbial activity, soil enzymes activities) [5]. Long-term studies into soil quality, or which evaluate soil recovery capacity after forest fires or post-fire silvicultural treatments, are scarce. To evaluate soil quality, the use of a general character parameter like soil respiration is commonly used [6, 7]. This study aimed to investigate soil respiration, microbial biomass and ratios (metabolic and MBC / TOC) in burnt and unburnt soils of an Aleppo pine forest ecosystem affected by a wildfire event 17 years ago. It is noteworthy that we define recovery as a scenario which returns to the same activity levels before wildfire perturbation. Our results demonstrated that 17 years after the fire event occurrence, the quality of the burnt soils reached the undisturbed soil levels. Contribution/ Originality
This study is one of very few studies which have investigated long-term recovery of the burnt Mediterranean soils, in dry and semiarid climates, and the paper’s primary contribution is finding that forest management must be taking into account soil parameters to achieve good adaptive procedural guidelines.

Effect of Different Concentrations of Vermicompost (Biohumus) On the Root Collar Diameter and Height Growth in the Seedlings of Anatolian Black Pine
In the present study, effect of vermicompost, a product of Biohumus®, on the root collar diameter and height growth of 1+0 aged seedlings of Anatolian black pine growing in Bartin-Turkey was investigated. Seedlings were treated with three different concentrations of vermicompost solution from seed dibbling. Statistical comparison of morphologic data for treatments was performed using ANOVA test while the treatments were categorised using Duncan test.Compared to control, mean root collar diameter growth was found to be about 25% higher in seedlings in V1 treatment type (Vermicompost of 1:1000) and nearly 26% more in V2 and V3 treatment type while height growth was 13% more in V1 treatment and 20% in V2 and V3 treatment.Findings of the study were thought that Vermicompost can be used to obtain quality black pine seedlings in nurseries by developing root collar and plant height. Contribution/ Originality
This study is important in terms detect the effect on forest tree seedling production of vermicompost fertilizer. Agricultural Sciences » Journal of Forests » Month: 06-2014 Issue: 2
Serum Rankl/Osteoprotegerin Complex and Endothelial Progenitor Cells in Chronic Heart Failure
The objectiveof this study was to assess an interrelationship serum RANKL/OPG complex with counts of circulating pro-angiogenic endothelial progenitor cells (EPCs) labeled as CD14+CD309+, and CD14+CD309+Tie2+ in patients with ischemic chronic heart failure (CHF).Methods: The study retrospectively evolved 153 patients (86 males) aged 48 to 62 years with exiting proven stable coronary artery disease (CAD). Systolic or diastolic CHF was defined among 109 (71.2%) patients. Twenty five 25 individuals were included in the control group. Circulating RANKL (sRANKL) and OPG were measured by high-sensitive ELISA kit at baseline. EPC populations were labeled by flow cytofluorimetry per High-Definition Fluorescence Activated Cell Sorter methodology.Results: Numerous of EPCs with phenotypes of CD14+CD309+ and CD14+CD309+Tie2+ were significantly lower in CAD patients when compared with healthy subjects. The trend to significant decrease of EPC numerous depending presence of CHF was found. The sRANKLlevel, OPG level, and sRANKL / OPG ratio were significantly higher in CHF subjects as compared to those without CHF (P=0.001). On multivariate analysis, CHF, sRANKL/OPG ratio, OPG, and NT-pro-BNP remained as independent predictors of decreased EPCs with phenotypes of CD14+CD309+ and CD14+CD309+Tie2+. When sRANKL/OPG ratio was added to the standard predictive model (CHF) improved relative integrated discrimination indices by 12.5% for CD14+CD309+ depletion, as well as by 17.3% for CD14+CD309+Tie2+depletion were found. Conclusion: We found that sRANKL/OPG ratio remained statistically significant predictor for depletion of pro-angiogenicEPCsin CAD patients. Contribution/ Originality
The paper’s primary contribution is finding that inflammatory cytokines, such as components of RANKL/OPG complex, areable to negatively modulate the level of circulating pro-angiogenicendothelial progenitor cells labeled as CD14+CD309+, and CD14+CD309+Tie2+ and thereby reduce a reparative potency of vasculature in heart failure patients.

Modelling and prediction of wind characteristics are essential design inputs in the development of wind energy systems. This paper exploits the characteristics of the Rayleigh probability density function to analyse the wind potential of all the regions of the republic of Cameroon. In the procedure, the probability density (PD) curves of some representative towns of the ten regions of Cameroon are presented. These curves highlight the fraction of time for which some wind velocity V prevails at the sites and the most frequent wind speed expected at these sites which coincide with the peak of the PD curves. We then proceed to calculate the power density of the sites, as well as the energy available for wind turbine extraction. We recommend the Savonius rotor for the regions of low wind speed based on its low cut-in speed of 1m/s. Contribution/ Originality
This study is one of very few studies which have investigated the wind energy potential of Cameroon in an exhaustive manner covering all the regions. It also proposes the prospect of harnessing the energy of the wind and recommends the Savonius rotor as the wind turbine generator of choice in Cameroon.

Dry Matter and Nutrient Accumulation of Selected Green Manure Species at Different Ages on Alisols at Areka, Southern Ethiopia
Research Article
Author(s):
Journal: International Journal of Natural Sciences Research
Continuous loss and net removal of soil nutrients from cultivated land causes a serious threat to the overall agricultural productivity. This decline in soil fertility is major constraint to agricultural production and food security in Ethiopian highland farming systems. Since farmers have limited capacity to invest in fertilizers, potential solution to the problem is to use green manure (GM) for their multiple advantages. Thus, the study was conducted to evaluate dry matter production and nutrient concentration from GM at different ages. The treatments were three levels of age (3, 4 and 5) months after planting (MAP), three GM species (Tithoniadiversifolia, Tephrosiavogelii and Crotalaria juncea) and laid out in factorial arrangement in RCBD design with three replications. T. diversifolia produced significantly (p<0.05) higher total above ground biomass (TAGB) at all ages. The TAGB yields of Tephrosiavogelii and Crotalaria juncea were lower by 35.85 and 68.82%, 32.96 and 27.12%, and 28.22 and 31.52% than the TAGB of Tithoniadiversifolia at three, four and five months after planting respectively. Nitrogen and K concentrations of all the GM species were relatively higher whereas P, Ca and Mg were low at all ages. In general, the study found appreciable dry matter yield and nutrient concentration from all species of different ages. Contribution/ Originality
This study contributes in the existing literature by providing information in organic fertilizers. The study provides options for poor farmers who have limited capacity to invest for commercial fertilizers and for those investors primarily engaged in organic farming. The paper provides initial information for researchers and students in further investigations. Engineering » International Journal of Natural Sciences Research » Month: 11-2014 Issue: 11
G-Force Exposure in a Contact Sport: The Use of Accelerometers to Quantify Physical Stress
GPS-based analyses of movement patterns are inadequate for quantifying the physical stress imposed on athletes in contact sports. Accelerometers may be useful for monitoring such athletes. The purpose of this study was to use triaxial accelerometers to record G-force exposure in Gaelic football players to examine differences in G-force exposure between games and practices and between playing positions. A small triaxial accelerometer with a flash memory chip data logger was fitted to the waistband of players’ shorts. Game and practice data were acquired at 100 Hz (scale ±16G) from 19 club level players (age 25±7 yr). Resultant G-force was: calculated for each data point from the raw accelerometer data collected in all three planes of motion and analyzed by quantifying the time spent above different G-force thresholds. Player positions were categorized as central (half backs/half forwards/midfield) and peripheral (full back/full forward) with central players typically more involved in continuous running. ANOVA with Bonferroni corrections was used to compare G-force exposure between games vs. practices, and between central vs. peripheral players (practice not position dependent). Differences between games and practices were apparent for time >3G, >4G, and >5G with more time at these thresholds in practices versus games (P=0.003), indicating higher G-force exposure in practices versus games. In games central players had greater time at >2G and >3G (P<0.001). Accelerometry analysis was effective in distinguishing player position-dependent differences in G-force exposure, and differences between games and practices. These differences indicate that the method of analysis of G-force exposure used here may be of utility for quantifying the physical stresses imposed on athletes in contact sports. Contribution/ Originality
This study is one of very few studies that have investigated physical stresses imposed on athletes in contact sports. Triaxial accelerometers can provide important information regarding the physical stress of an athletic exposure. These data may be important for monitoring playing intensity in a game or accumulated stress over a season. Physical Sciences » Journal of Sports Research » Month: 03-2014 Issue: 1

Journal: International Journal of Medical and Health Sciences Research
The present study was carried out to investigate the protective effect of L-ascorbic acid (A.A.), against mercury toxicity in albino rats. Twenty four males were divided into three groups. The control was fed a basic diet, whereas the other two groups were treated either by Hg alone (1g HgCl2/Kg food) or Hg-ascorbic acid (1g HgCl2/Kg food + 5% ascorbic acid), respectively, for 35 consecutive days. The following serum parameters were estimated; alkaline phosphatase (ALP), aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), urea, creatinine, uric acid, triglicerides, total cholesterol, HDL-cholesterol and LDL cholesterol.The present data obtained found that a significant decrease in serum ALP activity in mercury treated group, accompanied by a significant increase in serum ASAT. Furthermore, serum urea concentration was significantly higher in the mercury group compared to the control. However, the concentration of urea and the activity of ALP and ASAT of the Hg+ascorbic acid group were not statistically different from the control. Moreover, no significant variations were recorded concerning ASAT, creatinine and uric acid. The lipid profile; triglycerides, total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly varied between the three groups, despite the observed elevated concentration of triglycerides in Hg+ascorbic acid group. In conclusion, ascorbic acid may partially help in the protection against mercury intoxication and it could also be considered a safe nutritional source. Contribution/ Originality
This study is one of very few studies which have investigated protective effect of l-ascorbic acid mercury detoxication and physiological aspects and The paper’s primary contribution is finding that ascorbic acid may partially help in the protection against mercury intoxication and it could also be considered a safe nutritional source.

A Review of a Community Health Care Workers’ Programme in South Africa
Research Article
Author(s):
Journal: International Journal of Medical and Health Sciences Research
This study explored a Community Health Workers’ (CHW’s) programme from the point of view the CHWs, as well as the non-governmental organizations (NGOs) that managed them, by using a mixed-methods approach. A questionnaire was used to collect data from the CHWs, and semi-structured interviews were conducted with key informants and NGO representatives. It became evident that the CHW’s programmes are not contributing effectively to strengthening the health care system, and are merely playing the role of an ‘emergency response’ for patients suffering from HIV. The CHWs’ roles have never been formalised and CHWs are viewed as “volunteers” within the healthcare system, and therefore not given the necessary support. There is also a clear disconnect between the local health facilities and the CHWs’ programmes. Delays in receipt of payments from the Department of Health (DoH) hamper the NGOs’ ability to run viable organisations, which impacts on their ability to deliver desperately needed health related services. The multiplier effect of the aforementioned results, in further delays in the disbursement of stipends to the CHWs, which creates hardships for some of South Africa’s lowest paid workers who, are already shouldering financial and social burdens, which probably compromises the quality of critical services to those most in need. The overall impression is that as SA approaches the end of the second decade of democracy, it is a matter of urgency that primary health care (PHC) is viewed more seriously by the government and, more specifically the DoH. Contribution/ Originality
This study documents by way of a case study, the perceptions of Community Health Care workers and NGOs, on their role and importance in fortifying the health-care system in general and primary health-care specifically.
