Space-to-ground high-speed transmission is of utmost importance for the development of a worldwide broadband ***-infrared wavelengths offer numerous advantages for building such a system,spanning from low atmospheric attenuation to eye-safe operation and resistance to inclement weather *** demonstrate a full interband cascade system for high-speed transmission around a wavelength of 4.18μ*** low-power consumption of both the laser and the detector in combination with a large modulation bandwidth and sufficient output power makes this technology ideal for a free-space optical communication *** proof-of-concept experiment employs a radio-frequency optimized Fabry–Perot interband cascade laser and an interband cascade infrared photodetector based on a type-II InAs/GaSb *** bandwidth of the system is evaluated to be around 1.5 *** allows us to achieve data rates of 12 Gbit/s with an on–off keying scheme and 14 Gbit/s with a 4-level pulse amplitude modulation *** quality of the transmission is enhanced by conventional pre-and post-processing in order to be compatible with standard error-code correction.

Introduction: Thoracic wounds by firearms are frequent and severe. They may involve the patient’s prognosis. Objective: To study the epidemiological, clinical, paraclinical, therapeutic and evolutionary aspects of the thoracic wounds by firearms. Material and method: This was a cross-sectional, descriptive study of all patients over the age of 15 who consulted in the university hospital-YO in the department of general and digestive surgery over a period of 5 years. Results: We collected 50 cases of thoracic wounds by firearms on 183 thoracic wounds with a prevalence of 27.3%. There were 48 men (96%). The average age was 30 years. The patients came from urban areas in 66% of cases;the informal sector accounted for 44% of the cases. The pistol was the most involved firearm (46.9%). The consultation period was less than 6 hours in 78% of patients. An unstable hemodynamic state was found in 42% (n = 21). A fluid and mixed pleural effusion syndrome was found in 46% and 26% of patients, respectively. Associated lesions were diaphragm involvement, and lesions of intra-abdominal hollow organs. Thoracic drainage was performed in 24 patients (48%) and was associated with a laparotomy in 8 patients. The average hospital stay was 7.5 days. Mortality was 14%. Conclusion: the thoracic wounds by firearms are frequent in civilian practice. The thoracic CT allows mapping of the lesions and thoracic drainage constitutes the essential part of surgical treatment. The fight against the proliferation of weapons deserves to be promoted.

Attacks by swarm of bees realize arrays of mass poisoning. We report the case of a 9 years old boy whoes severity was related to the large number of bees which was about 400 and their locations spread throughout the skin surface with a preponderance to the cephalic end. Complications were hemolytic anemia, kidney failure and convulsions. The outcome was favorable with symptomatic care and hemodialysis.

Biliary tract cancers(BTCs) are highly fatal malignancies, which are often diagnosed at an advanced stage and have relatively poor *** treatment of patients with advanced BTC is systemic, based on chemotherapy or best supportive care, depending on their performance *** clinical trials studyingmany chemotherapeutic regimens and targeted therapies for the treatment of BTC, the standard of care for advanced BTC remains the combination of gemcitabine with *** new molecules targeting proliferation and survival pathways, the immune response and angiogenesis are currently undergoing phase Ⅰ and Ⅱ trials for the treatment of advanced BTC with promising results.

Background: Bacterial meningitis is one of the most severe infections in infants and children. It is associated with high mortality and neurological sequelae. In order to improve the prognosis of infants and children with purulent meningitis, we decided to conduct this study whose main objective was to identify the main pathogens responsible and describe the outcome in infants and children aged 2 months to 15 years admitted for purulent meningitis at the Yaounde Gyneco-Obstetric and Pediatric Hospital (YGOPH). Method: This was a cross-sectional study with retrospective data collection and consecutive sampling. Our study was conducted from 1 January 2009 to 31 December 2013. The patients included in the study were infants and children aged from 2 months to 15 years who were admitted for bacterial meningitis at the YGOPH, confirmed by bacteriological examination of cerebrospinal fluid (CSF) with identification of the pathogen by culture or soluble antigen. The data was analyzed using SPSS Version 18.0 and Excel 2007. The Chi-square test was used to determine the association of various variables. The significance threshold was set as P 0.05. Results: We selected 171 cases of purulent meningitis who represented 1.54% of admitted patients. The sex ratio was 1.2. We noted that 45% of our patients were aged 2 months to 1 year. The main presenting complaints were fever (98.8%), seizures (44.4%) and vomiting (28.7%). Haemophilus influenzae was found in 67 children (39.2%), followed by Streptococcus pneumoniae in 54 children (31.6%) and Neisseria meningitidis in 17 children (9.9%). Acute complications (status epilepticus, coma) were seen in 33% of patients. The statistically significant (P 0.05) factors for poor prognosis were aged from 2 months to 1 year (P = 0.0004), coma (P = 0.32), intracranial hypertension (P = 0.0001), the pathogen (P = 0.0032Pneumococcus), a delay of more than three days between the onset of the disease and the treatment (P = 0.0134) and brain abscess

Journal of Geoscience and Environment Protection 2019年第10期7卷 136-153页

A survey using the electrical resistivity and test pit methods is carried out in the Douala subbasin in order to investigate the sub-surface layering and evaluate the thickness of each layer through the variation of the resistivity with the depth. Applying the Schumberger array, a total of 48 vertical electrical sounding is conducted along 8 profiles directed W-E and using traditional method, 25 test pits with depth between 15 and 19 meters are done. Qualitative interpretation is carried out through the resistivity and test pit maps. The test pit maps reveal the presence of the following layers: The first layer of thickness varies from 0.2 to 2.0 m (average of 1.9 m). The thickness of the second layer varies between 0.2 and 4.0 m with an average of 2.8 m. The thickness of the third layer is between 2.0 and 4.0 m with an average of 3.8 m. That of the fourth and fifth layers ranges respectively between 4.0 and 6.0 m (average of 5.4 m) and between 2.0 and 6.0 m with an average of 4.4 m. Isoresistivities maps from resistivities computed for different AB/2 values (1.5;4.4;13.5;19;27.5;58 m) are generally characterized by the apparent resistivities which define many domains in function of the AB/2 values. The superficial layer is characterized by electric resistivity values ranging from 720 to 2073 Ωm for AB/2 = 1.5 m and probably represents pedologic materials. For other values of AB/2, resistivity varies from 253 to 32,381 Ωm (AB/2 = 4.4 m), 0.1 to 1838 (AB/2 = 13.2 m) with an average of 341 Ωm, 0.3 to 1608 Ωm (AB/2 = 19 m) with an average of 279 Ωm, 6.4 to 1427 Ωm (AB/2 = 27.5 m) with an average 291 Ωm, and 19.7 to 3555 Ωm (AB/2 = 58 m) with an average of 850 Ωm. These different values of resistivity represent the sedimentary materials.
