Touridomon Issa Somé, Abdoul Karim Sakira, Alidou Kaboré, Aissata Traoré
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.514134
Abstract: Groundwater is a main source of water supply for populations in Burkina Faso where there is a serious problem for drinking water access. However, water quality has not been always followed regularly. Recent studies showed that more than 50% of drillings in Yatenga province (north of Burkina Faso) have an arsenic concentration above the recommended WHO requirement. Preliminaries studies conducted in Bam (Center North of Burkina Faso) showed high arsenic level in certain localities. This work presents for the first time data on a large scale evaluation that had been performed in all the localities of Bam province in other to have a better assessment of contamination scale. A total of 707 drilling water samples have been selected randomly in 9 communes and analysed for the arsenic level using atomic absorption spectrometry with hydride generation. The results showed that 11% of drillings have an arsenic concentration above the recommended WHO requirements with Rouko commune having the highest rate of high arsenic level (22%).

Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.310006
Abstract: Parents play an important role in their children’s education. Their implication in the daily academic activities of their children can positively impact their results at the end of the year. The well-functioning of pedagogical activities could be more effective if parents and teachers join hands. So, parents must get involved in their children’s school community by actively taking part in the Parents Associations (APEs). This paper examines the traditional roles of APEs in Benin and the main problems they are facing. These include inadequate funds raising policies, the absence of solid cooperation with school teachers and the mismanagement of the existing. The paper therefore makes some recommendations on how APEs can be reorganized to better serve school communities using good examples from PTAs of United Kingdom.
Firm Governance and Organizational Resiliency in a Crisis Context: A Case Study of a Small Research-based Venture Enterprise
Alidou Ouedraogo,Michel Boyer
International Business Research , 2012, DOI: 10.5539/ibr.v5n12p202
Abstract: Very small companies that are derived from research projects face numerous crises throughout their lifetimes. These crises are presented in the literature as negative setback situations for the growth of these companies. However, some recent studies emphasize the role that a crisis can play as an agent of change by undergoing a thorough analysis of what transpired and proposing new avenues to avoid repeating such errors. This new approach to crisis management suggests that the crisis period be considered as an outstanding opportunity to learn, along with organizational resilience. Our study is part of this new approach towards crisis management and seeks to study the impact of crisis management on the resiliency of very small research-based company. The results show that a process of learning and resiliency transpires during the post-crisis period and represents three types of governance: financial, managerial and strategic.
Pacéré as the demiurge of orature
A Kaboré
Tydskrif vir letterkunde , 2007,
Abstract: Not all unwritten literatures are oral literatures. They would more appropriately be referred to as “spoken literatures”, in the wider sense of literatures that use different means of communication (mouth, gestures, body movement, instruments). The dumb “speak” with signs. Pio Zirimu proposed the term “orature” to palliate the alleged contradiction in the phrase “oral literature” or “spoken literature”. However, as a result of in-depth studies that revealed that before writing, there was a literature, which was spoken, many literary critics prefer the traditional phrase “oral literature” instead of the suggested term “orature”. The term “orature” has been taken up in performance studies to designate a genre of written literature at the cusp between spoken and written literatures, referring to written fictions that mix different performing genres. This paper aims at defining orature with an illustration from the poetry of Frédéric Titinga Pacéré and, consequently, to present him as the demiurge of this innovative genre in emerging Burkinabè literature. The implications of the genre of orature are manifold. Orature calls for a redefinition of literature as whatever a given society considers as literature. It demands an interpretation of literature based on an understanding of culture.
La lutte contre les glossines dans la zone agropastorale de Yalé (Burkina Faso): résultats d'enquêtes socioéconomiques
Kamuanga, M.,Kaboré, I.
Tropicultura , 2005,
Abstract: Tsetse Control in the Yalé Agropastoral Zone (Burkina Faso): Results of Socio-economic Surveys. The study examines the impact of a tsetse campaign (1994-1997) in southern Burkina Faso. In the absence of health - productivity monitoring, data were collected in cross sectional surveys to generate quantitative estimates of relevant productivity traits for cattle. The results indicate the following: 25% increase in herd size; reduction in mortality from 63.1% to 7.1% and increase in live births of 57.6%. Milk yield rose from 0.2 to 2.2 litres/cow/day in the dry season. These results show the impacts trypanosomosis control can have on zebu cattle exposed to a high tsetse challenge. The study underscores the importance of well designed surveys as a cost-effective way of generating estimates of productivity impacts. These estimates can be a useful alternative to subjective assessments in modelling the economic benefits.
Impact of Quantum Fluctuations on the Modulational Instability of a Modified Gross-Pitaevskii Equation with Two-Body Interaction  [PDF]

Abstract: Modulational instability conditions for the generation of localized structures in the context of matter waves in Bose-Einstein condensates are investigated analytically and numerically. The model is based on a modified Gross-Pitaevskii equation, which account for the energy dependence of the two-body scattering amplitude. It is shown that the modified term due to the quantum fluctuations modify significantly the modulational instability gain. Direct numerical simulations of the full modified Gross-Pitaevskii equation are performed, and it is found that the modulated plane wave evolves into a train of pulses, which is destroyed at longer times due to the effects of quantum fluctuations.
Dissipative Discrete System with Nearest-Neighbor Interaction for the Nonlinear Electrical Lattice  [PDF]
Sa?dou Abdoulkary, Tibi Beda, Serge Y. Doka, Fabien II Ndzana, Louis Kavitha, Alidou Mohamadou
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.36060
Abstract: A generalized dissipative discrete complex Ginzburg-Landau equation that governs the wave propagation in dissipative discrete nonlinear electrical transmission line with negative nonlinear resistance is derived. This equation presents arbitrarily nearest-neighbor nonlinearities. We analyze the properties of such model both in connection to their modulational stability, as well as in regard to the generation of intrinsic localized modes. We present a generalized discrete Lange-Newell criterion. Numerical simulations are performed and we show that discrete breathers are generated through modulational instability.

Marinette Thébault,Pascal Picard,Alidou Ouedraogo
International Business Research , 2013, DOI: 10.5539/ibr.v6n3p22
Abstract: The aim of this research is to analyse the experience of seniors navigating the Web for information on vacation travel by studying the sources of information and the means they use while researching and planning their vacation. Our international exploratory analysis is based on semi-directed interviews held with 22 French and Canadian seniors who used the Internet to research their tourism destinations. On the theoretical side, the research pointed out 4 different senior internet users: senior-Altruist, senior-Opportunist, senior-Disinclined and senior-Web2.0. It also shows that social interactions help improve the pertinence and the specific information sought. On the management side, our results help clarify the best communication strategies for the tourism industry insofar as using particular tools adapted for seniors and the Internet.

Abstract:

Haemonchus contortus is a blood-sucking abomasal helminth of small ruminants responsible for major economic losses to small farmers worldwide. Widespread resistance to synthetic anthelminthics has stimulated a need for alternative strategies of parasite control, among which is the use of medicinal plants with natural anthelminthic properties. This study assessed in vitro the efficacy of infused and macerated aqueous extract as well ethanolic extract of Moringa oleifera against fresh eggs, embryonated eggs, L1 and L2 larvae of H. contortus. For this purpose, five different concentrations (0.625, 1.25, 2.5, 3.75 and 5 mg/ml) were prepared from dry extracts via serial dilutions with distilled water. Fresh eggs obtained from artificially infected goat feces were exposed to these different concentrations for 48 hours, while embryonated eggs and larvae were exposed for 6 and 24 hours respectively. Distilled water and 1.5% DMSO were used as negative control. The results were expressed in terms of mean inhibition percentage of egg embryonation, mean inhibition percentage of egg hatch and mean percentage of larval mortality. An overview of results revealed that ethanolic leaf extract of M. oleifera was most efficient on eggs by inhibiting 60.3% ± 8.2% and 92.8% ± 6.2% eggs embryonation at 3.75 and 5 mg/ml respectively with a significant difference (P < 0.05), which contributed to obtaining the lowest LC50 value of 0.985 mg/ml. This extract also inhibited 99% ± 2%

Abstract: Influence of Nitrogen Fertilization and Management Practices on Dry Matter Production and Nutritional Value on Andropogon gayanus Kunth in Burkina Faso. The influence of nitrogen fertilization and harvesting practices on biomass production, chemical composition and nutritional value were studied on Andropogon gayanus Kunth forages set in Sudanese agroclimatic zone of Burkina Faso. The first year was spent to establish an adequate plant population, by transplantation of Andropogon gayanus stumps; then, four nitrogen doses were applied on experimental blocs during the second year: a) 0 N-units/ha (0 kilos of urea/ha) as Control, b) 18.5 N-units/ha (40 kilos of urea/ha), c) 37 N-units/ha (80 kilos of urea/ha) and d) 76 N-units/ha (150 kilos of urea/ha). Also, three harvesting intervals were applied as follows: harvesting i) every 30 days, ii) 40 days and iii) once at ear emergence. Each factor combination was repeated 4 times. Results indicated that treatment 67 N-u/ha combined with harvesting once at ear emergence led to the higher total dry matter (DM) production (7.6 tons DM/ha), while harvesting every 30 days showed the best expression of nitrogen fertilization effects. This harvesting interval (30 days), associated with moderate nitrogen fertilization dose (37 N-units/ha) gave an excellent forage containing 90 g DNM/kg DM, 0.81 French Feed Unit for Milk Cropping Andropogon gayanus Kunth under moderate fertilization doses and using adequate harvesting practice seems to be a suitable alternative to provide enough quantity of good quality forage.
