Crystal Structure Theory and Applications (CSTA) , 2014, DOI: 10.4236/csta.2014.34008
Abstract: A new compound of general formula {[(H2O)2K(μ-H2O)Sr]@[Cr(C2O4)3]}n (1) has been synthesized in water and characterized by elemental and thermal analyses, EDX, IR and UV-Vis spectroscopies and by single crystal X-ray structure determination. Compound 1 crystallizes in the chiral space group Fdd2 of orthorhombic system with a = 14.110 (4) ?, b = 36.074 (11)?, c =11.034 (3)? and Z = 16. Compound 1 is a coordination polymer in which the three-dimensional lattice framework is realized by the interconnectivity between K+ cations, Sr2+ cations, aqua ligands and [Cr(C2O4)3]3 complex anions. The asymmetric unit of 1 consists of one cationic motif formally written [(H2O)2K(μ-H2O)Sr]3+ and one anionic entity, [Cr(C2O4)3]3. The K+ and Sr2+ ions in the cationic motif are both eight-coordinate while the Cr3+ ions in the anionic complex are six-coordinate in a distorted octahedral geometry. Coulombic interactions between the ionic motifs and the three-dimensional H-bonding involving aqua ligands help to consolidate the bulk structure. Thermogra-vimetric analysis (TGA) shows that compound 1 is stable to heat up to ca. 80.
Boko Haram” In Nigeria: Religious Fanaticism As A Political Project

Sfera Politicii , 2011,
Abstract: Depuis le 11 septembre 2001, l’expression de la violence islamiste a pris un nouveau tournant. Bandits pour les uns, vaillants pour les autres, ces prosélytes se servent de la barbarie à des fins politiques avec un sens de l’imagination hardi. En Afrique subsaharienne, on vit une de violence interreligieuse et intercommunautaire au quotidien comme c’est souvent le cas au Nigéria. Dans ce pays de cent cinquante millions d’habitants, l’irruption tragique en juillet 2009 de la secte Boko Haram , avec son lot de cruauté contre les symboles de l’état, demeure dans les esprits, dans ce pays pourtant riche mais où la manne pétrolière est confisquée par une poignée de bienheureux . L’écrasante majorité de la population vit ici dans la misère et n’a d’autre recours que le repli communautaire et confessionnel insidieux et périlleux qui revêt une dimension politique.

Abstract: To understand the mechanism of infestation of stored groundnut in farming areas, studies on the inventory and geographical distribution of Caryedon species were carried out in the tree savannah and in producers’ storage structures. The incidence of C. serratus in stored groundnut was evaluated. Inventory and geographical distribution of insects belonging to Caryedon genus was achieved through a sampling in the savannah and producers’ granaries. The inventory and geographical distribution of insects was made throughout Burkina Faso whereas the evaluation of the perforations of groundnut pods was made in the western zone of the country. The results of the inventory showed the presence of two species belonging to Caryedon genus which are C. serratus and C. crampelii. These species are found on the agro-ecological zones of the country. The survival and maintenance of Caryedon species genus are ensured by the presence of plants belonging to various families such as Caesalpiniceae and Mimosaceae. The evaluation of the losses caused by C. serratus in producer’s stored groundnut revealed that the pods perforation rate varied according to the locality. In?Toussiana, the rate of perforated pods ranged from 53.72% to 100% in five months while in?Karangasso Sembla, for the same conservation time, the rate was in the range from 2.8% to 35%. However it is C. serratus which is responsible for the losses observed in the stored groundnut. Indeed, in the western area of Burkina Faso where more than 25% of the production is realized, 70% of
Pacéré as the demiurge of orature

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.

Application of resistant starch prepared from parkia flour was produced by replacement of wheat flour with 0, 5%, 10%, 15%, 20%, 30% and 40% Parkia flour. Processing, proximate composition, digestibility of resistant starch in bread and sensory quality were evaluated. Resistant starch was significantly (p < 0.05) increased as Parkia flour level increase in all breads. The resistant starch prepared from Parkia flour was 47.21%. However, wheat bread was 1.47% and Parkia bread 18.52% to 22.28% baked of (200℃ at 45 min) with 2.16% wheat bread and 31.74% to 35.05% Parkia bread baked of (130℃ at 90 min). Supplementation of wheat flour with Parkia flour 0 - 40% increased the crude protein content significantly (p < 0.05) from (7.89% - 15.68%), ash from (0.91% - 2.54%) and crude fiber (1.41% - 4.97%). Color of the bread treatments was remarkably affected by addition of different levels of Parkia flour. Therefore, Parkia flour could be added to wheat flour up to 15% without any observed detrimental effect on bread sensory properties. Sensory evaluation results indicated that bread with 5% to15% Parkia flour were rated the most acceptable and there was no significant difference in terms of acceptability compared to the control. This could be used to improve the nutritional quality of bread especially in developing countries were malnutrition is prevalent.

Abstract: In the Sahel, the climate and the agricultural practices are the main factors used to observe regreening process. But the extension of the latter not being uniform in the farming fields, we can suppose that there are other factors that contribute to the re-greening of certain zones and not others. The infiltrability of soils is considered as an important factor for these changes in the last decades. The influence of re-greening on the infiltrability of soils in the southern strip of Niger was studied through a comparison of zones according to the type of sandy soils (Jigawa/Rerey), siltyclay (Guiéza), silty-sandy (Hako) and clay-silty-sandy (Laka). The evaluated parameters are the texture, the infiltrability and the ecological characteristics (specific index of regeneration “SIR” and the Importance Value Index “IVI”). The main conclusions were: the soils of Niger South-Central are characterized by a sandy texture for more than 80%. The soils which are very sandy (“Jigawa”, “Rerey” and “Guieza”) are more permeable and have more trees contrary to the soil Hako and Laka. Their encrusting has the tendency to reduce the vegetation cover on the soil. The infiltration measurements indicated that the rate of initial and stationary infiltration diminishes while going down towards the South. In fact, it has been recorded a rate of 123 mm/min of initial infiltration and 87 mm/min stationary in Dan Saga on the sandy soils against 76 mm/min and 65 mm/min in Daré respectively for the initial and stationary rate. Therefore, the infiltration seems to influence the density, the SIR and the IVI of the trees from the North towards the South. Some additional work is necessary in order to determine the contribution of Farmer Managed Natural Regeneration (FMNR) in the improvement of the quality of soils and the movement of water in the superficial zones of the soil.

The beetle Caryedon serratusOlivier is a major insect pest responsible for the infesta-tion and damage on groundnut during storage. To understand the infestation mecha-nism of groundnut stocks, studies have been carried out on this insect biology under laboratory conditions in relation with its host plants. The results have demonstrated that the pre-oviposition on groundnut lasts on average 1.28 days. The oviposition pe-riod is 12.04 days, during which 80.42 eggs on average are laid. From hatching to adult stage, C. serratus larvae development goes through four stages with variable durations according to the stage. Three families of host plants (Papilionaceae; Caesalpiniaceae and Mimosaceae) were selected for females C. serratusto lay on their seeds. The re-sults showed that more eggs were laid on the seeds of Papilionaceae (98.75% of in-fested seeds) followed by Caesalpiniaceae (28.59% of infested seeds). Studies were carried out on the laying behavior of C. serratus under laboratory conditions and have revealed that whatever the conditions, C. serratus?females lay on all the plant species seeds exposed. Insects’ development duration has varied according to the plant species seeds used.

Abstract: This study on physical and physicochemical characteristics of household solid waste (HSW) in the city of Ouagadougou by using MODECOM, “Method of Characterization of Household waste” was done fifteen (15) years after the first study. Special attention has been paid to waste sampled and also to estimate energy content, namely the higher heating value (HHV) and the lower heating value (LHV). As a general tendency, the results showed a sensitive evolution in the physical parameters of waste (composition by size and composition by category) and also in the physicochemical parameters (moisture content and energy content). The results of HSW composition study showed that regardless the seasons, fermentable fraction is dominant (39% in the rainy season and 20% in the dry season) followed by plastics (18% in the rainy season and 20% in the dry season). The moisture content is measured to be 56.69% and 37.69% respectively in the rainy season and dry season. The results analysis of the potential of recovery showed that the organic recovery is more important (60% in the rainy season and 55% in the dry season) than the matter recovery (43% in the rainy season and 46% in the dry season). These results highlight the need for organic recovery and matter recovery of HSW in the city of Ouagadougou. The results from the analysis of the energy content showed that the HHV is estimated to be 17.94 MJ/kg in the rainy season and 17.96 MJ/kg in the dry season. The LHV is calculated to be 6.38 MJ/kg in the rainy season and 10.27 MJ/kg in the dry season. These results suggest that incineration as treatment of HSW in the city of Ouagadougou is not economically an appropriate option.

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.

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%).
