Surgical Science (SS) , 2018, DOI: 10.4236/ss.2018.912058
Abstract: Objectives: To evaluate the quality of the information provided to patients for their consent to be operated laparoscopically in the “A” surgery service of Point “G” University Hospital in Bamako (Mali). Methodology: The study was transversal, descriptive and prospective from November 1, 2016 to December 31, 2017 (14 months). It was performed at the general and laparoscopic surgery department of the Point “G” University Hospital in Bamako. Laparoscopically operated patients in scheduled or emergency programm whom consented the study and answered the questions before and after the surgical procedure were included. Results: One hundred patients were retained. The sex ratio was 4.2 for women. The surgery was scheduled in 93% (programmed surgery) of cases versus 7% (urgent surgery). Gynecological and obstetric surgery was performed in 54%, digestive surgery in 43% and laparoscopic exploration in 3%. The information was provided by surgeons, anesthetists, fellowship and students in respec-tively 63%, 6%, 11% and 9%. The reflection period before consenting to the act was greater or equal to 3 days in 90%. The media used were found to be suitable in 62%. The information was considered satisfactory preoperatively in 54% and postoperatively in 88%. Patients wanted additional information on post-surgery outcomes in 21%. Conclusion: The establishment of an information system and a free and informed consent form is a prerequisite for the quality of care in laparoscopic surgery.

Abstract: In addition to bioenergy production, Acacia magium, a fast growing species, plays a major role in climate change mitigation through carbon sequestration from the atmosphere. The objective of this study was to improve estimates of aboveground biomass of 3, 7 and 11 years old stands of Acacia mangium set up through natural regeneration at Anguédédou in C?te d’Ivoire. Tree measurements were done in circular plots of 615 m2 located at the center of each stand. 24 trees of circumference at breast height (cbh) between 31 and 116 cm were felled, weighed and measured. Multiple linear regressions were used to develop allometric equations linking aboveground biomass of trees to cbh and/or height. The carbon stock and sequestration capacity of each stand was assessed using these predictive models. The average cbh was 39.4 cm, 73.5 cm and 91.4 cm respectively for 3, 7 and 11 years old stands with a density ranging between 845 trees·ha-1 and 553 trees·ha-1. The allometric equations for biomass estimation were Btotal aboveground = exp(-3.455 + 2.081 × ln(C)), Btrunk = exp (-5.153 + 1.681 × ln(C) + 1.056 × ln(H)), Bbranches = exp(-2.005 + 0.498 × ln(C2 × H)), Bleaves = exp(-2.415 + 1.339 × ln(C)). Total height had no influence on total and leaf biomass but increased precision of trunk and branch biomass. The carbon sequestration capacity of aboveground biomass was highest in Acacia mangium stand of 7 years old with 45.14 teqCO2·ha-1·year-1 and lowest in the 3-year stand with 33.90 teqCO2·ha-1·year-1.
Migrants’ Remittances as a Source of Funding Local Development: Case of Burkinabè Migrants in C?te d’Ivoire  [PDF]
Zié Ballo, Coulibaly Okayo Alphonsine
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.87091
Abstract: This paper examines the possibility of directing remittances from Burkinabè migrants to the municipalities of their home country through loans. The descriptive results indicate that 94% of Burkinabè migrants agree to lend to the municipalities of their country. The econometric results obtained using the Tobit model show that variables of interest and economic variables such as profit, economic development, poverty reduction and job creation do not influence loan consent to the municipalities. On the other hand, cultural variables such as community spirit, unity, and mutual support, belief in God, conformism, and gerontocracy explain agreement to lend.

Bernard Coulibaly
Questions Vives : Recherches en éducation , 2011, DOI: 10.4000/questionsvives.227
Abstract: Dans cette contribution nous tentons d’analyser une situation didactique instrumentée sur une plate forme d’apprentissage à distance, situation dans laquelle des étudiants de Master 2 professionnel sont invités à réaliser un projet de service fictif. Cet apprentissage s’opère en groupe de 3 à 4 étudiants et vise l’acquisition de compétences en matière de conduite de projet de service dans le domaine de l’ingénierie en milieu socio-éducatif. L’article analyse, à partir des traces d’interaction, le processus de construction de ces savoir-faire en management de projet. Il met en évidence les stratégies de contournement et d’adaptation que les étudiants élaborent pour échapper aux contraintes d’une situation didactique fondée sur un dispositif pédagogique instrumenté .Il permet ainsi de comprendre le r le que des apprenants peuvent jouer dans la conception d’une situation didactique. In this paper we analyze an instrumented didactic situation that takes place on a distance learning platform. In this situation students in a professional master’s degree curriculum are invited to create a fictitious service project. They have to achieve this task in groups of 3 to 4 students. The task aims at making students acquire competences in terms of project management in the field of educational engineering. The article analyzes the process of building these skills in project management from traces of interaction. It highlights the strategies of circumvention and adaptation that students develop to escape the constraints of a teaching situation based on an instrumented educational device. It helps understand the role that learners can play in the design of a teaching situation.
Critique of John Locke Objection to the Innate Ideas  [PDF]
Coulibaly Yacouba
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.64030
Abstract: The debate about innetivism is not a new subject in philosophy. From the earlier philosophers up to the recent ones, the main question that remains is: men are born with some ideas or we only know through experience? In this study, the emphasis will not be the process of human knowledge but the controversy in the objection of Locke to the innate Idea. From the beginning of his objection, John Locke shows that we are born with empty mind. Then through experience we build the knowledge little by little. But later on, Locke recognizes that it’s also possible that children may have some ideas from the womb. They may experience wants, diseases, hunger, and heat. To him many of those ideas which were produced in the minds of children, in the beginning of their sensation, if they are not repeated in future, then they are quite lost. If we choose the fact that people are born with ideas from pre-experience, that view is more scientific and more logical than the religious view of Plato. The paper concludes that even though there is no complete agreement on how innate ideas are made, we did not come in the world with blank mind and what is important is not how innate ideas have been made but their existence and application in life.

Abstract: Objectives: The main objective of this study was to identify some yam assessions that are tolerant to the most invasive nematodes like Scutellonema bradys and Meloidogyne spp. Methodology and results: New assessions of Dioscorea spp. were screened in the savanna zone of central C te d’Ivoire. Fourteen of D. alata and thirty seven assessions of D. rotundata were tested respectively and separately against two and four local yam varieties in an augmented design from 2000 to 2001. Nine varieties of D. rotundata were more resistant to S. bradys and Meloidogyne when D. alata were less tolerant. The effect of S. bradys on D. alata was higher in 2001 compared to 2000. The effect of Meloidogyne was significantly (P<0.001) depressive on the production of D. rotundata every year while they were tolerant to S. bradys. Conclusion and application: Identified assessions among D. rotundata can be considered as promising varieties in nematode prone ecology. These varieties are 95/01864, 89/02665, 85/01864, 96/00480, 95/18937, 95/00902, BD10, 96/01524 and TDr608. More positive perspective can be achieved by crossing some clones of D. alata and these D. rotundata.

Abstract: This study aims at exploring arsenite (As (III)) removal from water using naturally available rocks (laterite, sandstone and shale) in C?te d’Ivoire. The study focused on the adsorbent dose, operating pH, contact time, initial arsenite concentration, and modelisation on the removal of arsenite by performing batch adsorption experiment with well water. The optimal dosage related to an initial As (III) concentration of 5 mg/L was about 50, 75 and 145 g/L for laterite, sandstone and shale respectively. Laterite has a better adsorption capacity in comparison to sandstone and shale. On the other hand, kinetic study reveals that the equilibrium times are 5 h for laterite, 3 h for sandstone and 8 h for shale. Results showed that laterite, sandstone and shale could remove the arsenic in groundwater at initial arsenic concentrations below 5 mg/L, satisfying the World Health Organization (WHO) standard for drinking water. Moreover, kinetics study showed that the overall adsorption rate of arsenite was described by the pseudo-second-order kinetic model.

Abstract: Objective: To determine the epidemiological and clinical characteristics of male hypofertility attending at urology for paternity desire. Materials and methods: Cross-sectional study conducted from January 1st to December 31 2012 at urology department of teaching hospital Yalgado Ouedraogo. We collated men attending for hypofertility. Only subjects living regularly with their partner were retained. Results: The study concerned 95 men. The average age was 36.9 years (range: 23 years and 53 years) and 28.6 years for their wives (range: 19 years and 40 years). Patients resided in urban areas in 90.5% of cases. Gynecologists and general physicians sent respectively 77.9% (N = 74) and 17.9% (N = 17) of cases. The average consultation delay time was 3 years. The average duration of infertility was 5.8 years (Extreme: 1 year and 20 years). Infertility was primary in 68.4% of cases and secondary in 31.6% of cases. 24.2% of patients admitted for history of genitourinary infection. Varicocele was found in 22.1% of cases. The semen analysis showed that 42 men had azoospermia. The semen culture isolated a germ in 19.1% of cases. Serum FSH was high in 47.3% of cases. Conclusion: Male hypofertility affected men of all age. Urologists are the last resort of the male hypo fertile, gynecologists constituting the first contact. Azoospermia is a problem commonly encountered in urological consultation.

Abstract: Bone tumors are infrequent within the scapula. Total scapulectomy with massive allograft reconstruction represents an attractive alternative to amputation when the whole scapula is invaded with tumor and the neurovascular bundle can be preserved during tumor resection. We report a case of resection of the scapula and proximal humerus for recurrent osteosarcoma with massive allograft reconstruction of the scapula and proximal humerus. A 22-year-old male patient was seen in February 1992 for a pathological fracture of the proximal left humerus. In July 1992, a resection of the proximal end of the humerus followed by a reconstruction with osteochondral allograft and nail osteosynthesis was performed. The postoperative course was uneventful. In September 2009, 17 years later, the patient presented with a huge tumor developed at the level of the scapula. There was no vascular or neurological symptom. Plain radiography showed an expansive osteolytic mass. CT scan demonstrated scapular and proximal humerus invasion. An extended assessment revealed the presence of two pulmonary nodules. The biopsy confirmed the recurrence of osteosarcoma. The indication of a resection of both the left scapula and the 1992 allograft which was completely invaded at its proximal portion and the complete reconstruction of the scapula and the proximal humerus with allograft was made. One year postoperatively, we note a favourable outcome in terms of musculoskeletal functions. Despite two resection surgeries of pulmonary nodules and chemotherapy treatments, the patient developed new lung metastases and an unfavourable outcome. Although shoulder function was almost completely eliminated following surgery, preservation of elbow, wrist and finger motion resulted in an acceptable level of postoperative limb function. This reconstruction appears to be an attractive technique to be used in similar cases. The necessity of a reliable tissue bank with quality allografts in sufficient number is paramount.
Evolution of Energetic Compounds, Antioxidant Capacity, Some Vitamins and Minerals, Phytase and Amylase Activity During the Germination of Foxtail Millet
Abdoulaye Coulibaly,Jie Chen
American Journal of Food Technology , 2011,
Abstract: This study was conducted to asses the energetic compounds (protein, fat and carbohydrate), some vitamins, minerals, antioxidant capacity, phytase and amylase activity during the germination of foxtail millet. Germination has been found to increase nutritive qualities of foxtail millet. One day soaking and germination up to 8 days increased significantly soluble sugars (reducing and total sugars), amylase activity from the first day to third day and phytase activity from first day to seventh day. The proteins were not changing during germination. Vitamins and minerals increased, however fat content and total phenolic content decreased through germination. Germination of foxtail millet for three days allowed obtaining flour with high amylolytic activity, high DPPH scavenging activity and high concentration of minerals, thus it can be added to different flour to initiate starch degradation and reduce viscosity, to control the minerals balance in children diet.
