Ouagadougou, Burkina Faso

Founded in 1974, the University of Ouagadougou is located in the area of Dawn Van Noord in Ouagadougou, Burkina Faso. In 1995 a second campus for professional education known as University Polytechnique of Bobo was opened in the city of Bobo Dioulasso and a third campus for teacher training in Koudougou in 1996 and in 2005 it became the University of Koudougou. The UO consist of seven Training and Research Units and one institute.The UO plays a key role in the economy and offers educational, cultural and economics benefit to the country. The current President of the University of Ouagadougou is Pr. Jean Koulidiati. The goal of the UO is to open new faculties in order to increase the number of students, to intensify the development of new information and communication technologies, to improve the university management, to improve the internal and external efficiency by diversification of the areas in education and to finally introduce a professional education.The University of Ouagadougou had around 40,000 students in 2010 .

To screen methanol and dichloromethane extracts of stem bark of Pterocarpus erinaceus for anti-inflammatory, analgesic, in vitro antioxidant activities and phytochemical analysis. Anti-inflammatory activity was determined by using carrageenan induced-edema of mice paw and croton oil-induced edema of mice ear; analgesic effect was evaluated using acetic acid-induced writhing. Phytochemical screening of extracts was performed by thin layer chromatography. The chromatographic fractionation led to the isolation of main active components as friedelin, lupeol and epicathechin. The structures were established by TLC and nuclear magnetic resonance studies. Both methanol and dichloromethane extracts, friedelin, lupeol and epicatechin showed a significant anti-inflammatory effect using croton oil induced-ear edema. Furthermore, the action of dichloromethane extract was more important. At the doses of 100 and 200 mg/kg, the methanol extract was able to reduce the carrageenan induced-hind paw edema, while at the doses of 100, 200 and 400 mg/kg, it showed an important analgesic effect against writhing induced by acetic acid injection of 38.8%, 68.0% and 74.3%, respectively. Antioxidative properties of methanol extract and its dichloromethane and ethyl acetate fractions were assessed by using the 1,1-diphenyl-2-picrylhydrazyl method. The methanol extract showed the stronger radical scavenging activity than dichloromethane and ethyl acetate fractions, with an antiradical power of 5, 3.5 and 2 respectively. The main components isolated from these extracts as friedelin, lupeol and epicathechin were responsible of these activities. The results suggest that the stem bark extracts of Pterocarpus erinaceus possessed important anti-inflammatory, analgesic activities and strong antioxidant properties, therefore, they could be used as potential natural ingredients in the pharmaceutical industry.

Energy Economics

This study empirically establishes the direction of causality between electricity consumption and economic growth in Burkina Faso for the period 1968-2003. The bounds test yields evidence of cointegration between electricity consumption, GDP, and capital formation when electricity consumption and GDP are used as dependent variable. Causality results indicate that there is no significant causal relationship between electricity consumption and investment. Estimates, however, detect in the long-run a bidirectional causal relationship between electricity use and real GDP. There is also evidence of a positive feedback causal relationship between GDP and capital formation. Burkina Faso is therefore an energy dependent country. It is also a country in which electricity consumption is growing with the level of income. All of this shows that electricity is a significant factor in socio-economic development in Burkina Faso; as such, energy policy must be implemented to ensure that electricity generates fewer potential negative impacts. © 2009 Elsevier B.V.

In the Man-Leo Shield, Paleoproterozoic (Birimian) belts crop out in nine countries of West Africa. Dominant domains include: (i) greenstone belts composed of plutono-volcanic, volcano-clastic and sedimentary rocks, deformed and weakly metamorphosed under regional greenschist facies conditions; (ii) widespread granitoid batholiths. The domains display a basin and dome-like architecture, and are overprinted by partitioned structures from successively shallower crustal depth.Analyses of key ductile and brittle structures has shown that the structural evolution of Man-Leo Shield is characterized by early vertical magmato-tectonics and subsequently, horizontal transcurrent tectonics with progression from ductile to brittle behavior. Basin and dome-like architectures, and the formation of an ubiquitous vertical foliation (MF) formed during emplacement of early amphibole-bearing (PAG) granite plutons at ca. 2.2Ga by diapirism during NW-SE crustal shortening. Subsequent to a late stage of predominantly NW-SE shortening that created steeply-dipping mylonite zones (Mz1), transcurrent faults became predominant. The formation of transcurrent faults began transpressively, with development of N-S trending regional-scale mylonite zones (Mz1), and a steeply-plunging stretching lineation that probably formed during emplacement of PAG-type granitoids ca. 2.15Ga. NNE-SSW transpressive sinistral horsetail faults and many NW-SE trending tension veins are interpreted to have formed at this stage. After cooling of the upper crust ca. 2.1Ga, transcurrent faults became strike-slip in character with formation of dominantly NE-SW dextral faults (Mz2) and the passive emplacement of biotite (PBG) granitoids. Clockwise rotation of the extensional stress axis (σ3) from NNE-SSW trending to ENE-SSW trending assisted the propagation of dextral NE-SW and sinistral NW-SE extensional en echelon horsetail faults. WNW-ESE trending extension jogs (Egz) are interpreted to have been initiated under the same stress conditions. Displacements on strike-slip/transcurrent faults are interpreted as the product of rotation of rigid nuclei blocks producing faults' re-activation.On the Man-Leo Shield Paleoproterozoic rocks are poorly exposed, but the tectonic model proposed in this study can help to shed light on the structural setting in areas of the shield which are poorly exposed, and in particular, why regional-scale structures do not display significant horizontal displacements. For practical use, key structural criteria can help to identify mylonite zones and transcurrent faults at different scales of investigation. © 2010 Elsevier Ltd. Source

Urban Studies

In many respects, easy access to water of good quality and in adequate quantity can be regarded as a basic social service that is central to both health and socioeconomic development. Having piped water in the dwelling or in the yard remains the best way of having low cost and easily accessible water, compared with water vendors or standpipes. However, international data estimate that only 35 per cent of urban population in sub-Saharan Africa have piped water access. This research uses event history analysis methods to study the factors affecting sustained piped water access in Ouagadougou, the capital city of Burkina Faso, where only 23 per cent of the urban population had piped water in 2010. The analysis demonstrates the relationship between aspects of one's life history-particularly residential status-and access to piped water. These results are discussed from the perspective of social and health issues. © 2012 Urban Studies Journal Limited. Source

Background: Vaginal fistula is a serious medical disorder characterised by an abnormal opening between the vagina and the bladder or rectum, which results in continuous leakage of urine or stool. The burden of this disorder in sub-Saharan Africa is uncertain. We estimated the lifetime and point prevalence of symptoms of vaginal fistula in this region using national household surveys based on self-report of symptoms. Methods: We considered all Demographic and Health Surveys (DHS) and Multiple Indicators Cluster Surveys (MICS) from sub-Saharan Africa and included data for women of reproductive age (15-49 years). We estimated lifetime prevalence and point prevalence of vaginal fistula with use of Bayesian hierarchical meta-analysis. Findings: We included 19 surveys in our analysis, including 262 100 respondents. Lifetime prevalence was 3·0 cases (95% credible interval 1·3-5·5) per 1000 women of reproductive age. After imputation of missing data, point prevalence was 1·0 case (0·3-2·4) per 1000 women of reproductive age. Ethiopia had the largest number of women who presently have symptoms of vaginal fistula. Interpretation: This study is the first to estimate the burden of vaginal fistula in 19 sub-Saharan Africa countries using nationally representative survey data. Point prevalence was slightly lower than previously estimated but these earlier estimates are within the prevalence's credible intervals. Although vaginal fistula is relatively rare, it is still too common in sub-Saharan Africa. Funding: None. © 2015 Maheu-Giroux et al. Open access article published under the terms of CC BY. Source
