The restoration of soils polluted by trace metals (Pb and Cd) by phytoremediation is an innovative and ecologically sustainable solution. The objective of the study was to develop a process of phytoaccumulation of trace metals (Pb and Cd) in soils with the species Panicum maximum. For this purpose, 30 buckets containing soil were used. These included six (06) buckets per dose of soil contamination by Pb and Cd (3 mg/kg and 9 mg/kg of Cd and 100 mg/kg and 300 mg/kg of Pb) and six (6) buckets containing uncontaminated soil (control). During a period of 90 days of experimentation, the concentrations of trace metals in the plant biomass and in the soils were measured. Also, the bioaccumulation (BF) and translocation (TF) factors, the mass of Pb and Cd taken up by the plant were determined. The results showed that the biomass produced was negatively influenced by increasing Pb and Cd concentration. The concentrations of Pb and Cd accumulated by P. maximum varied in the aboveground biomass from 6.48 ± 0.55 to 18.09 ± 0.71 mg/kg (Pb100);from 10.93 ± 0.38 to 23.04 ± 0.79 mg/kg (Pb300);from 0.91 ± 0.02 to 1.50 ± 0.03 mg/kg (Cd3);and from 3.05 ± 0.08 to 5.43 ± 0.09 mg/kg (Cd9) from day 30 to day 90. However, in the root biomass, trace metals (Pb and Cd) ranged from 8.09 ± 0.58 to 22.57 ± 0.86 mg/kg (Pb100);from 29.45 ± 0.49 to 62.35 ± 0.82 mg/kg (Pb300);from 0.66 ± 0.01 to 1.11 ± 0.07 mg/kg (Cd3);and from 2.22 ± 0.08 to 3, 97 ± 0.09 mg/kg (Cd9), from day 30 to day 90. Pb was concentrated in the root biomass and Cd in the aboveground biomass. Bioaccumulation factor values ranged from 0.26 ± 0.02 to 0.99 ± 0.04 (Pb100);from 0.21 ± 0.04 to 0.50 ± 0.06 (Pb300);from 0.83 ± 0.09 to 1.72 ± 0.18 (Cd3);and from 0.70 ± 0.08 to 1.54 ± 0.18 (Cd9). High concentrations of Pb and Cd show a negative effect on the accumulation potential of P. maximum.

Open Journal of Stomatology 2023年第10期13卷 342-352页

作者： Mathieu Millogo Motandi Idani Arsène coulibaly Michel Fabien Dargani Mahamadi Sanfo Tarcissus Konsem Department of Stomatology and Maxillofacial Surgery Tengandogo University Hospital Ouagadougou Burkina Faso Department of Stomatology and Maxillofacial Surgery Yalgado Ouédraogo University Hospital Ouagadougou Burkina Faso Department of Stomatology and Maxillofacial Surgery Ouahigouya Regional University Hospital Ouagadougou Burkina Faso

Introduction: Maxillofacial ballistic trauma is a serious injury that is difficult to manage, with significant complications and after-effects. The authors report their experience in managing this type of trauma in the context of insecurity linked to terrorism. Patients and Methods: This was a descriptive cross-sectional study with retrospective data collection covering the period from January 1, 2018 to December 31, 2022 in the stomatology and maxillofacial surgery departments of the university hospitals of Ouagadougou. Results: In 5 years, 52 patients were collected, i.e. 10.4 cases per year. The mean age of the patients was 31.46 ± 15.41 years, and the sex ratio was 3. In 67.31% of patients, these injuries were the result of shootings during terrorist attacks. The jugal (36.54%) and chin (32.69%) regions were the most affected. The mandible (36.54%) and zygomatic bones (28.85%) were the most injured bones in these traumas. All patients underwent surgical treatment, and 25% suffered secondary complications. All patients retained at least one sequela. Conclusion: Maxillofacial injuries caused by ballistic trauma are true emergencies that can be life-threatening and functionally disabling. Their management is delicate and the outcome is uncertain, hence, the prevention is important.

In this paper, the map of a network of air routes was updated by removing the non-optimal routes and replacing them with the best ones. An integer linear programming model was developed. The aim was to find optimal routes in superspace based on performance-based navigation. The optimal routes were found from a DIJKSTRA algorithm that calculates the shortest path in a graph. Simulations with python language on real traffic areas showed the improvements brought by surface navigation. In this work, the conceptual phase and the upper airspace were studied.

Geochemical Signatures of Séguéla Peridotites in the West African Craton

引用

Journal of Geoscience and Environment Protection 2022年第12期10卷 100-116页

作者： Allialy Marc Ephrem Dicko Kagou Houssou N’guessan Nestor Kouamelan Alain Nicaise coulibaly Yacouba Laboratory of Geology Mineral and Energy Resources (LGRME) Faculty of Earth Science and Mineral Resources Félix Houphoue&#235 t Boigny University Abidjan C&#244 te d’Ivoire

The present study deals with peridotites found in the paleo-proterozoic domain of the Leo Man Shield, Séguéla region, west-central of Côte d’Ivoire. Results show that Séguéla peridotites are composed of lherzolites, dunites and harzburgites. However, iherzolites are the most abundant. The phenocrysts in these rocks are olivine most often serpentinised, and pyroxenes, represented by diopside and enstatite. Amphiboles are divided into two groups: magmatic amphiboles and those from the destabilization of clinopyroxene. Spinels have CrO3 content which varies between 28% and 37%, Al2O3 between 33% - 41% and MgO is equal to 18%;they are poor in TiO2 and do not contain zinc oxide. Séguéla peridotites are characterised by a negative anomaly in Nb-Ta, associated with an enrichment of lithophilic elements and light rare earth elements with a fractionation rate (La/Yb) which varies between 46.22 and 150.72 and heavy rare earth elements, and HFSE depletion, which may suggest that were formed in an art context, that is, a mantle enriched by fluids from a subduction zone. However, another hypothesis could be considered, that of the interaction between the mantle and magmas in a subduction zone context.

Dynamic denoising studies in wideband radio channel measurement and modeling

引用

The Journal of China Universities of Posts and Telecommunications 2014年第5期21卷 43-46页

作者： coulibaly Balla Moussa ZHAO Xiong-wen LIANG Xiao-lin LI Shu LI Yi-wei School of Electrical and Electronic Engineering North China Electric Power University

The fixed level and dynamic denoising method was studied based on indoor-to-outdoor measured channel impulse responses ORs） at 5.25 GHz with radio frequency （RF） 100 MHz bandwidth. It is found that the dynamic ranges, peak powers and noise floors of the IRs are with close correlations. The comparisons with different denoising methods are given by deriving the power delay profiles （PDPs）, root mean square （RMS） delay spread （RMS DS）, number of paths （NOPs） and Ricean K-factors. It is concluded that the traditional fixed level noise cut is under estimate of DS and NOPs. The Ricean K-factors are of little sensitive to noise cut irrespective of what kind of methods applied. The PDPs are not very sensitive to the fixed level noise cut, however, obvious changes can be found by dynamic noise cut. The dynamic noise cut is preferred when clear noise floors is observed and decided from the measured IRs, it＇s of importance in data post processing for wideband radio channel measurements as well as the relevant modeling work.

Open Journal of Epidemiology 2023年第4期13卷 372-384页

作者： Tiembré Issaka Tetchi Sopi Malthide coulibaly Adama Christiane Djoman Dagnan N’cho Simplice Dosso Mireille Félix Houphouë t Boigny University Abidjan C&#244te d’Ivoire National Institute of Public Hygiene Abidjan C&#244te d’Ivoire National Institute of Public Hygiene Adzopé C&#244te d’Ivoire Pasteur Institute of Cô te d’Ivoire Laboratory Abidjan C&#244te d’Ivoire

Introduction: Rabies is a highly fatal viral disease outside the post-exposure prophylaxis (PEP). Data from previous studies and reports from the rabies center show that cases of death from human rabies are regularly reported, despite training measures for health workers, awareness-raising and communities, and the availability of vaccines. Objectives: The aim of this study was to analyse the determinants of human rabies deaths in Côte d’Ivoire from 2016 to 2022. Method: A retrospective cross-sectional qualitative study was carried out from January to August 2023 on all the records of patients who died of human rabies at the Treichville Rabies Center from 2016 to 2022. An analysis of the rabies center’s annual activity reports from 2016 to 2022 was also carried out in order to complete the information gathered from the files. Results: The socio-demographic characteristics showed that out of 148 deaths, children accounted for 47.97% (71) and 66.22% (98) of rabies deaths were male, with an M/F sex ratio of 1.96. In terms of clinical characteristics, in 97.30% (144) of cases, the deceased had presented with furious rabies, and analysis by the Pasteur Institute of Côte d’Ivoire laboratory confirmed 101 cases (92.66%) of human rabies. Geographical distribution showed that cases of human rabies were recorded in 56 health district, and 64% (94) of the deceased lived in rural areas. The main causes of the occurrence of rabies were essentially non-use of post-exposure prophylaxis (PEP) and missed vaccination due to ignorance. Conclusion: In view of these results, control strategies and interventions need to be adapted to the epidemiological characteristics of the disease, using a community-based approach with a view to eliminating dog-transmitted rabies by 2030.

Open Journal of Modern Neurosurgery 2022年第1期12卷 1-8页

作者： D. Kanikomo M. Diallo A. Tokpa I. Sango Y. Sogoba M. S. Diarra B. Sogoba M. Dama O. coulibaly M. coulibaly M. Diallo Department of Neurosurgery Teaching Hospital Gabriel Touré Bamako Mali Department of Neurosurgery Teaching Hospital of Bouaké Bouaké C&#244 te d’Ivoire Department of Radiology Teaching Hospital Gabriel Touré Bamako Mali Department of Neurosurgery Luxembourg Hospital of Bamako Bamako Mali Department of Neurosurgery Mali Hospital Bamako Mali

Pregnancy, which is responsible for the decline in immunity, and the immediate postpartum period can lead to reactivation or worsening of tuberculosis. We report a case of a patient who consulted for neurological disorders in the context of a deterioration in general condition. The CT scan revealed a brainstem lesion which was successfully treated like a tuberculosis. However, reactivation has been observed in the postpartum period of a pregnancy contracted during anti-tuberculosis treatment. Further clinical improvement has been achieved with anti-tuberculosis treatment. Pregnancy and the immediate postpartum had led to a transient decline in immunity in part by decreasing in the inflammatory activity of type 1 helper T cells so that the fetus, which is a foreign body, was accepted by the maternal body. This decline in immunity during pregnancy and the immediate postpartum period due to immune reconstitution had been responsible for a high degree of vulnerability, usually characterized by a significant exacerbation of tuberculosis symptoms and an unfavorable course of disease.
