Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.411092
Abstract: The mobile communication is nowadays one of the basic needs of humanity. It is essential to the flourishing of human beings. Considering this reality, the need to use its mobile phone is become more important and diversified. The subscribers of the various mobile telephone operators are increasingly demanding. This situation poses the problems of the cover mobile network to the operators and leads them to opt for several solutions and investments. The mobile operators in order to satisfy their customers use a policy of pushing the limits of network coverage in time and space for festive moments in targeted zones. Thus, we have conducted a study on the topic: study of a kit of GSM radio site for event-driven movable coverage. This work is applied to GSM (Global system mobile) network of the operator Orange-Ci, leader of mobile telephony in Ivory Coast. We thus proceeded under investigation initially of the various aspects of the ordinary sites (motionless radio site) which are already deployed with Orange-Ci in order to impregnate us infrastructures and equipment used. This study revealed us that a radio site comprises 4 parts: infrastructures, installations and energy equipments, installations and radio equipments, and installations and equipment of transmission. After the first analysis, we made a study of the movable site. The study of the movable site enabled us to see the various possible solutions to fulfill the basic functions of a movable radio site. After analysis we retained that our radio site will be built on a truck on which a mast of 25 m maximum length for the antennas will be embarked, it will be fed by a generator also embarked on the truck and the solution of transmission selected is the transmission by satellite more precisely technology VSAT. We choose the various equipments (radio, transmission, energy) according to features which we defined to constitute the kit of movable radio site.
A New Enhanced Soil Adjusted Vegetation Index: HYBRID
Adama Ouattara,Bruce E. Frazier,Abdourahamane Konare
Online Journal of Earth Sciences , 2012,
Abstract: First-order soil brightness effects are accounted for with orthogonal indices and Soil Adjusted Vegetation Indices (SAVI) and particularly true at very low Leaf Area Indices (LAI). However, they have limited dynamic range and they fail to account for residual soil brightness effects observed at intermediate LAI. The objective of the study is to devise an index from existing ones that would overcome these shortfalls. First, a graphical method is shown to give a general formulation for the orthogonal vegetation indices (i.e., ADVI). Then, from the analysis of ADVI, it is shown that ratio and orthogonal are functionally equivalent under certain conditions. Finally, by combining ADVI and SAVI, the new hybrid index (HYBRID) obtained is the least affected by soil brightness effects at all LAI values, has the greatest dynamic range, is the most sensitive to LAI changes, saturates at very high LAI and seems to evolve linearly with LAI.

Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.87022
Abstract: Introduction: The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle. The etiologies are diverse. Mali is a country where urinary schistosomiasis is endemic. Repeated infestation may result in long-term ureteropelastic dilatation secondary to stenotic sequelae. The objective is to study the causes of dilatations of the upper urinary tract. Materials and Methods: This is a prospective study of 12 months, from October 2010 to September 2011, performed in the urology department of Gabriel Toure University Hospital in Bamako. The parameters studied were: age, sex, reason for consultation, medical history, urinary analysis, etiological diagnosis, management, evaluation of renal failure. Result: In 12 months, we collected 50 cases of dilatations of the upper urinary tract representing 0.66% of all consultations. The average age of our patients was 35 years old. The sex ratio was 2.13 in favor of men. A history of urinary schistosomiasis was found in 25 patients or 50%. Low back pain was the most common reason for consultation, 76%. The renal and bladder ultrasonography performed in all 50 patients in our series found bilateral dilatation in 68% of patients and unilateral dilation in 32% of cases. Urinary tract infection with Escherichia coli was found in 53% of cases. Ureterovesical reimplantation was performed in 40% of cases. Conclusion: The dilatation of the upper urinary tract, consequence of an anatomical or functional obstruction, constitutes a rather frequent pathology and constituted 10% of the surgical acts of our service. Etiologies are diverse: congenital and acquired. Open surgery gives good results, but the introduction of innovative minimally invasive surgical technique is necessary.

Open Journal of Urology (OJU) , 2014, DOI: 10.4236/oju.2014.44006

We reported a case of an intravesical foreign body in a 16 years old teenager for abortion attempt. During laparotomy for suspected pelvic appendicitis, we incidentally discovered an intravesical foreign body. From this first observation in our urology division, we reviewed the literature on the nature and circumstance of self introduction in bladder of foreign body and their surgical ablation. We emphasized the importance of endoscopy as a support of diagnosis and therapeutic of intravesical foreign body. This observation also highlighted the lack of information in our teenagers about reproductive and sexual health.

Advances in Sexual Medicine (ASM) , 2014, DOI: 10.4236/asm.2014.41001
Abstract: Objective: To study erectile dysfunction in diabetic patients seen in two clinics in the city of Bobo-Dioulasso, Burkina Faso. Materials and Methods: A prospective cross-sectional descriptive study was conducted at the Souro Sanou Teaching Hospital (CHUSS) and the Saint Leopold clinic in Bobo-Dioulasso, from March 1 to September 1, 2012. A total of 107 patients data were collated and analysed, which was then grouped into two: the ED group, designating patients with erectile dysfunction and the NED group consisting of those patients without. The sample comprised of 61 patients with types 1 and 2 diabetesand were aged between 25-70 years. The IIEF-5 was used to evaluate erectile dysfunction. Results: The prevalence of erectile dysfunction was 57%. The average age of patients was 54.4 ± 8.3 years. All patients with ED had type 2 diabetes. The mean disease duration of diabetes was 7.2 ± 6 years. Erectile dysfunction was severe in 32.8% of cases, moderate in 31.1% of cases and mild in 36.1%. Its severity was significantly associated with glycated hemoglobin, triglycerides and BMI. Phosphodiesterase types 5 (PDE5) inhibitors were found to be effective in the treatment of erectile dysfunction with a satisfactory therapeutic response in 77.4% of users. Conclusion: Erectile dysfunction is a common complication in diabetic patients. Its occurrence and severity are influenced by several factors. The potential presence of this disorder should be assessed due to its negative impact on quality of life. Phosphodiesterase type 5 inhibitors are an effective treatment modality in diabetic patients.

Objective: To study the epidemiology and current trend in the management of urologic complications following obstetric and gynaecologic surgeries at CUUA University hospital of Cotonou. Patients and Methods: It was a retrospective study of patients referred with urologic complications following obstetric and gynaecological surgeries. The study took place at the Teaching Clinic of Urology Andrology at CNHU of Cotonou between April 1, 2008 and March 31, 2013. Results: Forty-one patients were studied. They represented 3.5% of people hospitalized at CUUA throughout the study period. The average age was 41 years swith range of 20 and 57 years. Twenty-one (51.2%) of them were married. Thirty patients (73.2%) were referred from a non-academichospital, while 7 patients (17.1%) were referred from academic hospital. Caesarean section was the primary gynecological surgery in 22 cases (53.7%) and hysterectomy in 19 cases (46.3%). Clinically, the pre- dominant symptoms were leakage of urine throughout the vagina and obstructive anuria with or without back pain. We found 31 cases of VVF, 5 cases of bilateral ligation of the ureters, 3 cases of unilateral ligation of the ureter, 1 ureteralinjury and 1 uretero-vaginal fistula. These complications were diagnosed postoperatively in 95.1% of cases. Surgeries done included VVF repair in 31 cases (75.6%), unilateral ureteral reimplantation in 4 cases (9.8%), removal of ligation of the ureters in 3 cases (7.3%), bilateral ureteral reimplantation for 2 cases (4.9%) and end-to-end anastomosisin 1 case (2.4%). The postoperative period was uneventful in 29 cases and we observed 7 cases of surgical site infection. The overall success rate was 87.8%. Conclusion: Urological complications following gynecologic surgeries managed at the urologic department of teaching hospital of Coto-nou had an even higher incidence. Early diagnosis especially during the operative procedure would save the patients’ serious complications and open surgery due to the lack of endo-urological facilities. The most important factor in prevention is good knowledge of pelvicanatomy and good knowledge of the surgical techniques of caesarean operation section and trans-abdominal hysterectomy.

Abstract: Objective: To describe the epidemiological, clinical and therapeutic aspects of cases of vaginal bleeding in the nonpregnant patient received in emergency at Yalgado OUEDRAOGO University Hospital. Materials and Methods: It was a retrospective and descriptive study that involved the clinical records of 326 patients collected from January 01, 2009 to December 31, 2013. Results: The average age of women was 47 years old with extremes at 12 and 82 years old. Women of childbearing age accounted for 61.6% and postmenopausal women 18.7%. 70.7% of women were pauciparous or nulliparous. Menorrhagia and pelvic pain were the main signs associated. This symptomatology required hospitalization in 85.2% of cases. The main aetiologies were uterine myomas 49.69%, cervical cancer 23% and functional metrorrhagia 11.04%. Progestin was the most used drug in 67.1% of cases. Total abdominal hysterectomy and abdominal myomectomy were the most commonly used surgical methods with 22.3%, 44.4% of cases. Eleven death cases were observed. Conclusion: Gynecological metrorrhagia is more common in women of childbearing age than in menopausal women. The main causes are fibroma, cervical cancer and functional metrorrhagia.

Abstract: Objective: The objective of our study was to study the surgical activities carried out in the gynecology-obstetrics department of the CHU-YO (Teaching Hospital Yalgado Ouédraogo) from January 1st 2015 to December 31st, 2015. Patients and Methods: This dealt with a cross-cutting descriptive and analytic study with retrospective data collection. Our study has included the female patients who underwent surgery in the operating room and whose medical records were usable. Results: 45% of female patients admitted in the concerned department underwent a surgery. The average age of patients was estimated at 28.02 years ±7 years with extremes of 13 years and 80 years. Obstetrical surgery has involved 89.9% of cases. Female patients have received a loco-regional anesthesia in 92.7% of cases. Emergency surgical operations accounted for 88.8% and caesarean section was the main surgical operation carried out in 87.1% of cases. The mortality rate of the overall surgical operations was 1.04%. Conclusion: A better availability of labile blood products is more likely to reduce the mortality rate of surgical operations under the threshold of 1%.

African Journal of Laboratory Medicine , 2013, DOI: 10.4102/ajlm.v2i1.81
Abstract: Background: Resistance of malaria parasites to existing drugs complicates treatment, but an antimalarial vaccine that could protect against this disease is not yet available. It is therefore necessary to find new effective and affordable medicines. Medicinal plants could be a potential source of antimalarial agents. Some medicinal plants from Burkina Faso were evaluated for their antiplasmodial and cytotoxic properties in vitro. Methods: Crude dichloromethane, methanol, water-methanol, aqueous and alkaloids extracts were prepared for 12 parts of 10 plants. Chloroquine-resistant malaria strain K1 was used for the in vitro sensibility assay. The Plasmodium lactacte dehydrogenase technique was used to determine the 50% inhibitory concentration of parasites activity (IC50). The cytotoxic effects were determined with HepG2 cells, using the tetrazolium-based colorimetric technique, and the selectivity index (SI) was calculated. Results: Sixty crude extracts were prepared. Seven extracts from Terminalia avicenoides showed IC50 < 5 μg/mL. The IC50 of dichloromethane, methanol, aqueous and alkaloids extracts ranged between 1.6 μg/mL and 4.5 μg/mL. Three crude extracts from Combretum collinum and three from Ficus capraefolia had an IC50 ranging between 0.2 μg/mL and 2.5 μg/mL. Crude extracts from these three plants had no cytotoxic effect, with SI > 1. The other plants have mostly moderate or no antimalarial effects. Some extracts from Cordia myxa, Ficus capraefolia and Opilia celtidifolia showed cytotoxicity, with an SI ranging between 0.4 and 0.9. Conclusion: Our study showed a good antiplasmodial in vitro activity of Terminalia avicenoides, Combretum collinum and Ficus capraefolia. These three plants may contain antiplasmodial molecules that could be isolated by bio-guided phytochemical studies.
