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: 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: Tomato (Lycopersicon esculentum Mill) is quantitatively the highest vegetable consumed in Burkina Faso. The objective of this study was to evaluate the physico-chemical, nutritional characteristics, and sanitary quality of the tomato variety Mongal F1 from different production sites. Twenty-eight (28) samples of Mongal F1 fresh tomatoes were collected from 28 producers at three different localities of Ouahigouya, Loumbila and Ouagadougou. The physico-chemical and nutritional characteristics were determined by standardized methods and the traces metallic elements by atomic absorption spectrophotometry. The results revealed a degree brix varying from 4.07° to 5.50° and a pH ranging from 3.71 to 4.08 corresponding to a total acidity of 0.39% to 0.55% citric acid equivalents. The moisture content, the ash content, the total carbohydrates content, the reducing carbohydrates content, the lipids content and the protein content were ranged from 95.09% to 96.17%, 9.25% to 10.60%, 47.00% to 53.43%, 30.03% to 41.21%, 3.04% to 7.71% and 17.09% to 25.03% respectively. The results of the trace metals showed a high accumulation of total cadmium from 0.11 to 0.22 ppm, of total lead of 1.15 to 1.27 ppm and arsenic total of 0.19 to 0.20 ppm. The results proved that environmental conditions influence the quality of the tomato Mongal F1. Detection of trace elements in the tomato fruits suggests that a better production practices are needed.

Abstract: Background: The current adult prevalence of HIV in India is 0.34%. HIV infected persons should have adequate knowledge about the modes of transmission of infection. This is essential for reducing the risk of secondary infection, preventing coinfection from other viruses such as hepatitis B and for protecting the uninfected. Identification of the correlates of poor knowledge among HIV positive subjects will aid in planning effective measures to improve their health knowledge about HIV. Aims: To explore HIV related knowledge among HIV positive subjects and to determine the correlates of their knowledge. Methods: The study was conducted between November 2005 and May 2007. Two hundred HIV positive subjects attending a tertiary care hospital and three non-governmental organizations in Puducherry, South India, were recruited for the study. They were interviewed using a pre-tested structured questionnaire regarding their knowledge about HIV and were divided into those with HIV knowledge score >90% and those with score ≤90%. The data were analyzed using Chi-square test and logistic regression. Odds ratio (OR) and 95% confidence intervals were also calculated. Results: The median knowledge score was 90%. Knowledge on the modes of HIV transmission was better than that on the modes by which it does not spread. Subjects who had received counseling (OR: 16.78), studied above class 10 (OR: 4.13), and those with duration of more than 1 year since diagnosis (OR: 3.12) had better HIV knowledge score (>90%). Persons counseled by HIV positive peers had a better knowledge. Conclusion: This study revealed the importance of counseling in improving the HIV related knowledge among HIV positive individuals. It also highlights the beneficial effect of peer counseling.

Abstract: Sesame cultivation is strategic for the economy of Burkina Faso. Indeed, after cotton, sesame is the second most important agricultural product for exportation. However, its production is limited by plant diseases and pest attacks. Facing this situation, large amounts of pesticides are used to boost productivity. But, these chemicals have a negative impact on soil fertility. In this instance, the effects of Supraxone and Lambda-super in the presence of compost on soil microbial activity under rainfed sesame cultivation in a peasant environment were studied. The experiment design was a block of Fisher (BCR) comparing the non-treated parcel (TNT) to the parcel amended only with compost (C) and to the parcel amended with compost and treated with the pesticides (C + P), respectively. Soil samples were taken at depths of 0 - 20 cm before sowing at 41st and 81st days after sowing. Respiratory activity and soil microbial biomass were monitored respectively by respirometric tests and by the fumigation-incubation method. The results show that the addition of compost into the soil with or without supraxone treatment and Lambda-super resulted in an increase in microbial biomass and soil respiratory quotient. These results show that the provision of compost in sufficient quantity corrects the inhibitory effect of soil biological activity by pesticides.

Abstract: Penile fracture is a rare urological emergency. It occurs mainly in young adults during sexual intercourse. In many instances, one of the corpora carvanosus is involved though bilateral injuries with or without corpus spongiosus involvement is not uncommon. However, isolated injury to corpus spongiosus is extremely rare. We report a case of isolated rupture of corpus spongiosum secondary to penile injury during coitus in a 43-year-old man that presented to University Hospital Souro Sanou of Bobo Dioulasso. He presented with history of persistence bleeding per urethra following penile injury during sexual intercourse. The Retrograde urethrography (RUG) showed a partial rupture of urethra, Moore type 3. Complementary penile ultrasound revealed extensive contusion of the urethra with circumferential hematoma and rupture of the distal 1/3 of the corpus spongiosus. He had gentle per urethral catheterization which was left for one month. Penile ultrasound sound done after removal of catheter showed residual injury and narrowing of the urethra.

Abstract: Introduction: Calcified forms with pseudo-tumor symptomatology of chronic subdural hematomas are rare. They are the result of slow bleeding over several years. The main etiology is related to the complications of the ventriculo-peritoneal shunt (VP). The purpose of this study was to recall the peculiarities and physiopathology of its pseudotumoral hematomas through 2 observations. Observation: Case 1: 8-year-old patient with a history of ventriculoperitoneal shunt at 3 months of age for congenital hydrocephalus, was admitted for functional impotence of the left-side of the body of insidious onset spreading over 9 months in a chronic headache, blurred vision and generalized seizure. CT scan showed a heterogeneous subdural hematoma of the right frontoparietal with calcifications. The patient underwent an excision by morcellation of a yellowish, friable partly calcific mass. The postoperative history was marked by a total recovery of the neurological deficit. There was no recurrence at 6 months postoperatively. Case 2: 11-year-old adolescent, treated with VP shunt at 6 months of age for post-meningitic hydrocephalus, was admitted for helmet headache, dizziness, lightheadedness and apathy progressing for 3 years. CT scan showed hypodensity of right peri-hemisphere with calcified linings, exerting a mass effect on the medial structures. The patient was given a block excision of a calcific mass with blood content. The evolution was marked by the complete resolution of seizures and hemiparesis. There was no recurrence at 6 months postoperatively. Conclusion: Calcified subdural hematomas are rare and consecutive to

The development and the revolution of nanotechnology require more and effective methods to accurately estimating the timing analysis for any CMOS transistor level circuit. Many researches attempted to resolve the timing analysis, but the best method found till the moment is the Static Timing Analysis (STA). It is considered the best solution because of its accuracy and fast run time. Transistor level models are mandatory required for the best estimating methods, since these take into consideration all analysis scenarios to overcome problems of multiple-input switching, false paths and high stacks that are found in classic CMOS gates. In this paper, transistor level graph model is proposed to describe the behavior of CMOS circuits under predictive Nanotechnology SPICE parameters. This model represents the transistor in the CMOS circuit as nodes in the graph regardless of its positions in the gates to accurately estimating the timing analysis rather than inaccurate estimating which caused by the false paths at the gate level. Accurate static timing analysis is estimated using the model proposed in this paper. Building on the proposed model and the graph theory concepts, new algorithms are proposed and simulated to compute transistor timing analysis using RC model. Simulation results show the validity of the proposed graph model and its algorithms by using predictive Nano-Technology SPICE parameters for the tested technology. An important and effective extension has been achieved in this paper for a one that was published in international conference.

Abstract: This article proposes the design and the results of a project studying the adoption of mobile gaming (playing mobile games) in the Chinese youth market. An adoption model extending TAM (Technology Adoption Model) was used, with intention to use as the dependent variable. Data were gathered from a sample group consisting of university students both Chinese and Foreigners. It was found that adopters of mobile gaming were likely to be male as well as female, and also that the group surveyed exhibited a behavior towards relatively high spending on mobile entertainment (in proportion to income). The key factors affecting mobile gaming adoption in portion China were Perceived Ease of Use, Perceived Enjoyment, Social Influence and Flow. Perceived expressiveness, economic cost was found to be the most significant influential factor affecting intention to use, while perceived enjoyment was found to be motivated by perceived ease of use. Recommendations regarding developing and offering mobile games are also included.
