Abstract: Introduction: Cattle are strong animals very often used in agriculture in rural Africa. Unpredictable in their behavior, they regularly inflict injuries to farmers, some of whom are children in rural Africa. Objective: The purpose of this study was to describe the clinical, therapeutic and evolutionary aspects of abdominal trauma caused by bovidae to children on farms in Burkina Faso. Patients and Method: This is a descriptive study covering the period from January 2014 through December 2016 and was conducted in the General Surgery Unit of the Tenkodogo Regional Hospital in Burkina Faso. It included all patients under the age of 17, victims of abdominal trauma by cattle on farms. Result: A total of 68 patients were identified, which is 3% of all patients under 17 admitted to the service during the same period. The average age of patients was 10.5 years, with a standard variation of 3.6 years. The majority (73.5%) of the patients were boys. The main lesional mechanisms found were horn strokes (88.2%). We noted 35 eviscerations without visceral perforation, 15 intestinal perforations, 6 hepatic wounds and 5 splenic wounds. In 7 cases, there were non-penetrating wounds. All patients underwent surgical intervention under anesthesia. The average length of hospital was 6 days. Two deaths were recorded, making a mortality rate of 3%. Conclusion: Abdominal traumas of the child by attack of cattle are frequent during farm works in rural Burkina Faso. The injuries are sometimes serious. Wearing protective equipment for children should be considered during farm work.

Abstract: Current limitations related to the development of effective, durable and reliable MEA components for PEFC applications are addressed. Advancements made in the development of materials (catalysts, high temperature membranes, bipolar plates, etc.) for PEFC are shown. The effect of the catalyst on PEFC performances based on cells fed by hydrogen, direct methanol, direct propane, or direct acetal fuels are presented. The progress in cell performance and cathode research are discussed. Perspectives related to CO tolerance anodes are indicated. The effect of the membranes on the cell performance are shown and parameters which may help the development of appropriate membranes depending on the fuel are suggested. Openings for the future in materials processing and development for PEFC mass production are discussed. The development of New Materials is the key factor to meet those requirements. The aim of this paper is to present challenges related to the development of new materials for PEFC applications and perspectives related to components cost issues are discussed.

Pakistan Journal of Nutrition , 2004,
Abstract: Eight strains of lactic acid bacteria producing bacteriocin were isolated from Burkina Faso fermented milk samples. These strains were identified to species: Lactobacillus fermentum, Pediococcus spp., Leuconostoc mesenteroides subsp. meseteroides, Lactococcus. Isolated bacteriocin exhibited antibacterial activity against Enterococcus faecalis 103907 CIP, Bacillus cereus 13569 LMG, Staphylococcus aureus ATCC 25293, Escherichia coli 105182 CIP using the agar drop diffusion test. The inhibition diameters obtained with bacteriocin are between 8 mm and 12 mm. Gram-positive indicator bacteria were most inhibited. The activities of the bacteriocin were lost after treatment with all the proteolytic enzymes (alpha-chymotrypsin, trypsin, pesin), whereas treatment with lipase, catalase, alpha-amylase did not affect the activity of the bacteriocin.

Pakistan Journal of Nutrition , 2009,
Abstract: Dèguè was a traditional fermented food (pearl millet dough) which consumed in Burkina Faso. In this work, the traditional processing of pearl millet into dèguè was investigated in 18 traditional production units. This study was followed in Ouagadougou and Bobo-Dioulasso. The main steps of diagram of production were dehulling, winnowing, washing, drying, milling, sieving, kneading, cooking, pounding, shaping and fermentation. Before fermentation, crude protein, crude fat, ash, starch and carbohydrates content were respectively 5.43; 3.00; 1.13; 33.37 and 41.81 %. After 72 hours of fermentation only protein content (6.12 %) was increased; starch content was(23.6 %) decreased. pH and titratable acidity were respectively 6.75 and 0.12 before the fermentation and after 72 hours pH (4.49) was decreased and titratable acidity (0.57 g of 100 grams of lactic acid) was increased. Microbiology analyses indicated that the number of lactic acid bacteria, yeasts and moulds increased during the course of fermentation. The number of coliforms was decreased slightly after 72 hours of fermentation.

Abstract:

In developing countries, efforts to face food insecurity were revealed by construction of dams and hydro-agricultural managements. This study aimed to establish sanitary consequences in a hydro- agricultural zone. Methods: Data from 1847 children were analysed. Kato-Katz and concentration in MIF were used for intestinal parasites; research of microscopic haematury was used for urinary schistosomiasis. Nutritional status was estimated by WHZ and HAZ indexes. Association between malnutrition and independents variables was measured in univariate and multivariate analysis. Results: Among children, 80.1% were infested by at least one parasite, 30.8% by S. mansoni and 49.6% by S. haematobium. Prevalence of emaciation and prevalence of stunting were respectively, 32.6% and 25.5%. In the multivariate analysis: Age: (1 - 3 y age group, OR = 2.92, 4 - 6 y age group OR = 1.85, p < 0.001); S. mansoni (OR = 1.27, p < 0.027) and S. haematobium (high OR = 1.53, low OR = 1.44, p = 0.008), were associated with emaciation. Age: (4 - 6 y age group, OR = 1.78, 7 - 11 y age group OR = 2.55, p < 0.001) and S. haematobium (high OR = 1.58, low OR = 1.28, p = 0.005), were associated with emaciation. Conclusion: Development of bilharziasis (urinary and intestinal) with increased morbidity and malnutrition, attenuate benefits expected from hydro-agricultural managements. It is important to invest in the control of water-related diseases, which are amplified by hydro-agricultural managements.

Convergence of complex multiplicative cascades
Julien Barral,Xiong Jin,Beno\,{?}t Mandelbrot
Mathematics , 2008, DOI: 10.1214/09-AAP665
Abstract: The familiar cascade measures are sequences of random positive measures obtained on $[0,1]$ via $b$-adic independent cascades. To generalize them, this paper allows the random weights invoked in the cascades to take real or complex values. This yields sequences of random functions whose possible strong or weak limits are natural candidates for modeling multifractal phenomena. Their asymptotic behavior is investigated, yielding a sufficient condition for almost sure uniform convergence to nontrivial statistically self-similar limits. Is the limit function a monofractal function in multifractal time? General sufficient conditions are given under which such is the case, as well as examples for which no natural time change can be used. In most cases when the sufficient condition for convergence does not hold, we show that either the limit is 0 or the sequence diverges almost surely. In the later case, a functional central limit theorem holds, under some conditions. It provides a natural normalization making the sequence converge in law to a standard Brownian motion in multifractal time.
Uniform convergence for complex $[\mathbf{0,1}]$-martingales
Julien Barral,Xiong Jin,Beno?t Mandelbrot
Mathematics , 2008, DOI: 10.1214/09-AAP664
Abstract: Positive $T$-martingales were developed as a general framework that extends the positive measure-valued martingales and are meant to model intermittent turbulence. We extend their scope by allowing the martingale to take complex values. We focus on martingales constructed on the interval $T=[0,1]$ and replace random measures by random functions. We specify a large class of such martingales for which we provide a general sufficient condition for almost sure uniform convergence to a nontrivial limit. Such a limit yields new examples of naturally generated multifractal processes that may be of use in multifractal signals modeling.
