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%).

Abstract: Few studies have been conducted on the epidemiology in pregnancy in sub-Saharan Africa. This study aimed to improve the care of pregnant women infected with hepatitis B virus (VHB) and their newborns in the urban district health. Method: This study was conducted from 01/09/2014 to 01/09/2015. Study involved three types of data collection: a collection of data from health facilities involved in the project; repeated cross-sectional survey among health personnel; a pros- pective study of pregnant women identified positive for HBsAg and followed at the University Hospital Yalgado Ouédraogo (CHU-YO). Knowledge assessment was made among health staff and pregnant women using a knowledge score. Construction of the score came after a factorial analysis of multiple correspondences on population health workers surveyed in the first round (N = 119) on one hand and all pregnant women (N = 266) on the other hand. This had identified among the 79/19 questions, those that discriminated best knowledge of paramedics and pregnant women. For pregnant women, this score was then dichotomized from the center and logistic regression was performed to determine the sociodemographic, medical and obstetric characteristics that influenced it (p value < 005). Results: Health staff had been surveyed twice (N = 119/100). In general, the level of knowledge was good on targeted knowledge, both before and after training. No health worker routinely offered screening for hepatitis B among pregnant women attending antenatal clinics. Altogether 266 pregnant women HBsAg-positive were referred and followed CHU-YO. Half of the patients had a score lower than 2/17. Univariate analysis showed that variables such as education level influenced significantly the level of knowledge. Women with higher levels of education had a higher level of knowledge about the disease, compared to those of primary level [OR = 1.63; [1.34 to 1.99], p value < 0,001]. Newborns during the study period numbered 128 and the vaccine was made in the first 24 hours of life for 83.6% of them. Conclusion: routine screening for infection with VHB during pregnancy and improved knowledge of mothers is strongly reco- mmended in Burkina Faso.

Abstract: Over one school year, 15 ml RPO was added to individual meals 3 times a week in selected primary schools in two sites. Serum retinol was measured with HPLC at baseline and exactly 12 months later to take account of seasonality. A simple pre-post test design was used in the Kaya area (north-central Burkina), where 239 pupils from 15 intervention schools were randomly selected for the evaluation. In Bogandé (eastern Burkina), 24 schools were randomised for the controlled intervention trial: 8 negative controls (G1) with only the regular school lunch; 8 positive controls (G2) where the pupils received a single VA capsule (60 mg) at the end of the school year; and 8 schools with RPO through the school year (G3). A random sample of 128 pupils in each school group took part in the evaluation.In Kaya, serum retinol went from 0.77 ± 0.37 μmol/L at baseline to 1.07 ± 0.40 μmol/L one year later (p < 0.001). The rate of low serum retinol (<0.7 μmol/L) declined from 47.2% to 13.1%. In Bogandé, serum retinol increased significantly (p < 0.001) only in the capsule and RPO groups, going from 0.77 ± 0.28 to 0.98 ± 0.33 μmol/L in the former, and from 0.82 ± 0.3 to 0.98 ± 0.33 μmol/L in the latter. The rate of low serum retinol went from 46.1 to 17.1% in the VA capsule group and from 40.4% to 14.9% in the RPO group. VA-deficient children benefited the most from the capsule or RPO. Female sex, age and height-for-age were positively associated with the response to VA capsules or RPO.RPO given regularly in small amounts appears highly effective in the reduction of VA deficiency. RPO deserves more attention as a food supplement for VA and as a potential source of rural income in Sahelian countries.Vitamin A (VA) deficiency affects approximately 40% of the world population, particularly pregnant or lactating women and under-five children [1]. An estimated 100–140 million children are still suffering from subclinical VA deficiency, although clinical signs of the deficiency are on the decli

Abstract: The aim of the present study was to evaluate the levels of arsenic in tube-well water, food and residents' urines samples in Yatenga province, Burkina Faso. The prevalence of skin lesions was evaluated as well. The study was cross-sectional in design. It was conducted during April 2009. Permanent residents of 20 villages were included in the study. Water samples were collected from 31 tube-wells located in the selected villages. Tomatoes, cabbages, and potatoes produced in the selected village were randomly sampled. Arsenic content in water, food, and residents' urine was determined by atomic absorption spectrophotometry using hydride generation method. Finally, 240 people were examined by a medical doctor for skin lesions. Arsenic concentrations from the tube-well water ranged from 1 to 124 μg/l. Arsenic concentrations of more than one-half (52%) of the water samples exceeded the WHO guideline value (10 μg/l). No trace of arsenic was found in the samples of tomatoes, cabbages, and potatoes. Variation in arsenic concentrations in the urines was correlated to arsenic concentrations in tube-well water. Clinical examinations revealed that melanosis and keratosis were respectively identified in 29.26% and 46.34% of the population. Both conditions were observed in 24.39% of the population. The frequency of skin lesions was positively associated with the arsenic concentration in tube-well water. A great majority (89.53%) of those who had skin lesions were at least 18 years old. In conclusion, chronic arsenic poisoning remains a major public health problem in the province of Yatenga (Burkina Faso).

Abstract: Cone-beam CT (CBCT) scanners are based on volumetric tomography, using a 2D extended digital array providing an area detector [1,2]. Compared to traditional CT, CBCT has many advantages, such as less X-ray beam limitation, and rapid scan time, etc. However, in CBCT images the x-ray beam has lower mean kilovolt (peak) energy, so the metal artifact is more pronounced on. The position of the shadowed region in other views can be tracked by projecting the 3D coordinates of the object. Automatic image segmentation was used to replace the pixels inside the metal object with the boundary pixels. The modified projection data, using synthetically Radon Transformation, were then used to reconstruct a new back projected CBCT image. In this paper, we present a method, based on the morphological, area and pixel operators, which we applied on the Radon transformed image, to reduce the metal artifacts in CBCT, then we built the Radon back project images using the radon invers transformation. The artifacts effects on the 3d-reconstruction is that, the soft tissues appears as bones or teeth. For the preprocessing of the CBCT images, two methods are used to recognize the noisy black areas that the first depends on thresholding and closing algorithm, and the second depends on tracing boundaries after using thresholding algorithm too. The intensity of these areas is the lowest in the image than other tissues, so we profit this property to detect the edges of these areas. These two methods are applied on phantom and patient image data. It deals with reconstructed CBCT dicom images and can effectively reduce such metal artifacts. Due to the data of the constructed images are corrupted by these metal artifacts, qualitative and quantitative analysis of CBCT images is very essential.

Abstract: This paper proposes a novel approach for the automatic detection of allergy test (allergy lesion). A hyperspectral microscope system was used to image the test samples which were diagnosed by dermatologist. It was found that allergy of different levels, and healthy skin cells show absorption spectra, which are sufficiently characteristic and yet reproducible enough to allow for differentiation when using a spectroscopic system. Principal components analysis was used to extract relevant features that could be used for classification from these spectra. Preliminary results indicate that the different types of allergy cells can be reliably distinguished by these features. We conclude that hyperspectral microscopic analysis is a promising approach for improving and automating the diagnosis of allergy test as well as another skin lesions.

Macroeconomic Determinants of the Mobilization of Tax Revenues of the Countries of the West African Economic and Monetary Union (WAEMU)  [PDF]
Issa Larba Kobyagda
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.101017
Abstract:

This article aims to analyze the fiscal potential of UEMOA member countries. The question of the fiscal potential of the states is of great importance since the domestic resources represent a high proportion in the financing in Plans and strategies of economic and social development. In this article, we adopt the technique of stochastic border estimation, which is more intuitive—and potentially more relevant for policies—to measure the potential and fiscal effort over the period 1990-2017. The results show that the tax burden is determined by structural factors and that, in most countries, the tax potential is underutilized. Similarly, the fiscal effort shows poor performance in terms of resource mobilization in the majority of countries. These results show that the WAEMU countries can reach or exceed the tax rate of 20% minimum set by the UEMOA if efforts are made to better tax the informal sector. The main contributions of this article have been to justify empirically the increase of the minimum pressure rate in the UEMOA from 17% to 20% and to demonstrate that a better taxation of the agricultural sector would considerably affect the mobilization of tax revenues.

American Journal of Food Technology , 2009,
Abstract: To promote the consumption of squashes flesh, the vitamin A potential of steamed-dried squashes from Cameroon was evaluated in determining the beta-carotene content through HPLC method in raw, steamed and steamed-dried peeled flesh of three squashes species: Cucurbita moshata cv. Dickinson, Cucurbita maxima cv. Hungarian Blue and Cucurbita pepo cv. Sacred Indian Rattle. The vitamin C and total lipids contents were also titrated with 2, 6 dichlorophenol indophenol dye and extracted with hexane in a soxhlet apparatus for 6 h, respectively. The moisture content was estimated by drying in an oven at 105°C until constant weight. The beta-carotene contents of dried steamed squashes were 2834.75±11.22; 3043.91±1.65 and 5917.83±720.49 μg/100 g serving of C. pepo, C. moshata and C. maxima, respectively. The vitamin C contents ranged from 5.70±0.32 μg/100 g serving (C. moshata) to 11.81±0.19 μg/100 g serving (C. maxima). Total lipids ranged from 6.22±0.00 g/100 g serving (C. pepo) to 7.09±0.11 g/100 g serving (C. moshata) and the water remaining ranged from 6.39±1.18 g/100 g serving (C. maxima) to 8.19±0.70 serving (C. pepo). Drying of steamed squashes seemed to result in a significant concentration of beta-carotene content (71 and 89 times higher than those of steamed squashes). The same effect was observed for the vitamin C content (about 1.7 times) and the total lipid content (6 to 12 times). These results suggest that as a ready to eat product, steamed-dried squashes could contribute to fight against vitamin A deficiency if they are well conserved.
An Aspect-Oriented Approach for Use Case Based Modeling of Software Product Lines  [PDF]
Stéphane S. SOMé, Pauline ANTHONYSAMY
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.24032
Abstract: Software Product Line Development advocates software reuse by modeling common and variable artefacts separately across members of a family of products. Aspect-Oriented Software Development aims at separation of concerns with “aspects” to increase modularity, reusability, maintainability and ease of evolution. In this paper, we apply an as-pect-oriented use case modeling approach to product line system modeling. A use case specification captures stake-holders concerns as interactions between a system and its actors. We adapt our previous work with the introduction of a “variability” relationship for the expression of variabilities. This relationship is used to model variable and common behaviours across a family of products as use cases. A variability composition mechanism enables building of executa-ble behaviour models for each member of a product line family by integrating common elements with the applicable variable elements.
