Background: Postpartum eclampsia is a life-threatening obstetric emergency. Its management is multidisciplinary. Despite measures taken to accelerate the reduction of maternal, fetal and infant mortality in Burkina Faso, maternal deaths related to postpartum eclampsia persist. The aim of the study was to investigate the epidemiological, clinical and prognostic aspects of postpartum eclampsia in the obstetrics department of the Sourô Sanou University Hospital in Bobo-Dioulasso. Method: This was a descriptive cross-sectional study with retrospective data collection covering the period from June 1, 2018 to May 31, 2019. We included 76 patients in the study;the variables studied were the epidemiological, clinical and prognostic aspects. The data collected were entered on a microcomputer and analyzed with the EPI info version 7.2 software. Results: The prevalence of postpartum eclampsia was 0.87% compared to admissions to the obstetrics department. The average age of the patients was 23 years old with the extremes of 15 and 39 years old. Primiparas accounted for 39.47%, housewives 53%, and home births accounted for 15.79%. Seizures accounted for 55% of the reasons for admission, the average time to onset of these seizures postpartum was 3.8 days with extremes of 1 and 30 days with 45% of seizures occurring postpartum immediately. Maternal complications were noted in 42.10% of cases with 5 cases of Hellp syndrome, 3 cases of renal failure, and 3 cases of acute pulmonary edema. We recorded 4 cases of maternal death, representing a case fatality rate of 5.2%. Conclusion: Postpartum eclampsia is common in the obstetrics department of the Souro Sanou University Hospital Center with a significant case fatality rate. Emphasis should be placed on monitoring and prevention, especially women at risk of developing postpartum eclampsia for better maternal prognosis.

Bamako’s geographic and demographic expansion is sure to increase the need for water, and the slow development of the water supply network seems unable to meet this need. The knowledge of the approximate quantity of water reaching the groundwater is crucial, given the high dependence of this city and its surrounding area on groundwater. The aim of this study is to estimate the average groundwater recharge on a monthly scale, based on measurements taken over a 24-month period by using Water Table Fluctuation (WTF). The monthly recharge values obtained from the 15 piezometers in the study area by using WTF method vary from 1.04 to 38.81 mm with an average value of 9.74 mm. As part of the precipitations, these values represent respectively 1.29%, 48.52% and 12.17% of monthly average precipitation. It appears in this study that despite the piezometers belonging to the same climatic zone, the recharge rate can be different because of many factors such as the thickness of the aquifers, the soil and geology type, the local land cover and land use activities.

The mango, a fruit of immense economic and dietary significance in numerous tropical and subtropical regions, plays a pivotal role in our agricultural landscape. Accurate identification is not just a necessity, but a crucial step for effective classification, sorting, and marketing. This study delves into the potential of machine learning for this task, comparing the performance of four models: MobileNetV2, Xception, VGG16, and ResNet50V2. These models were trained on a dataset of annotated mango images, and their performance was evaluated using precision, accuracy, F1 score, and recall, which are standard metrics for image classification. The Xception model, with its exceptional performance, outshone the other models on all performance indicators. It achieved a staggering accuracy of 99.47%, an F1 score of 99.43%, and a recall of 99.43%, showcasing its remarkable ability to accurately identify mango varieties. MobileNetV2 followed closely with performances of 98.95% accuracy, 98.85% F1 score, and 98.86% recall. ResNet50V2 also delivered satisfactory results with 97.39% accuracy, 97.08% F1 score, and 97.17% recall. VGG16, however, was the least effective, with a precision rate of 83.25%, an F1 score of 83.25%, and a recall of 85.47%. These results confirm the superiority of the Xception model in detecting mango varieties. Its advanced architecture allows it to capture more distinguishing features of mango images, leading to greater precision and reliability. Xception’s robustness in identifying true positives is another advantage, minimizing false positives and contributing to more accurate classification. This study highlights the promising potential of machine learning, particularly the Xception model, for accurately identifying mango varieties.

本文旨在探讨中国-塞拉利昂跨区域发展合作和弗里敦在非洲转型的最新经验。近几十年来,令我们惊讶的是,弗里敦在21世纪已经从一个军事基地转变为非洲大陆西北沿海地区的旅游城市。尽管“一带一路”倡议(The BRI Initiative)存在争议,但本文发现,中国在塞拉利昂的基础设施项目一直是为当地民众和社会提供可持续发展的一种重要动力。在这种现实背景下,对于弗里敦转型经验的利弊及其客观评估,我们试图利用塞拉利昂首都弗里敦的历史经验进行案例研究,弥合当前学术研究与现实世界之间所存在的不可忽略的巨大差距。在这种时代性的现实背景下,本研究重点分析了中国在塞拉利昂的投资对非洲国家国内主要部门的积极影响:(1)塞拉利昂正在进行之中的强调经济增长的现代化发展方案,(2)强调当地交通连通性的更大基础设施建设,以及(3)扩大旅游业,强调新兴产业。因此,通过把重点放在弗里敦最近的转型方面上,这一新的努力有望促进非洲的区域稳定和塞拉利昂经济结构的日益多样化。在第一章中,文章通过对现有研究成果的考察和实证数据分析,不仅试图提供概述,而且加深对中国-塞拉利昂发展合作(和基础设施合作)如何使弗里敦从20世纪的军事基地转变为21世纪的旅游城市的理解。文章分析了弗里敦如何在过去内战期间成为军事行动的地理基地,后来通过中塞跨区域的发展合作(和基础设施合作)将弗里敦转变为在非洲大陆西北海岸的旅游城市之一。本研究详细地探讨了中国基础设施项目如何帮助非洲国家塞拉利昂实现其新的发展目标。总的来说,所有这些都可能产生溢出效应,从而积极地引发旅游业的创造及其在这个非洲国家塞拉利昂的首都弗里敦取得一定程度上的成功。本文通过对道路基础设施建设等积极影响的案例研究,强调中国引导的海外基础设施投资与塞拉利昂经济多元化之间存在的一种关联性。在第二章中,文章重点进行了关于塞拉利昂和弗里敦的案例研究:(1)中国对塞拉利昂的基础设施援助,以及(2)21世纪的弗里敦如何从军营基地转变为旅游城市。对于中塞的基础设施合作和对外援助而言,这有着深厚的近代历史根基。自1970年代以来,中国一直扮演着外国投资者和塞拉利昂发展议程合作伙伴的重要角色。值得注意的是,这些伙伴关系在各个工业部门取得了许多成就,例如(1)能源、(2)农业、(3)教育和(4)公共卫生部门。因此,在它们的长期积极影响的支持下,可以说塞拉利昂近年来在社会经济发展方面取得了长足的进步。有鉴于此,文章从跨区域发展合作的角度出发,讨论了塞拉利昂与中国的外交关系,以及中国-塞拉利昂在(跨区域的)基础设施合作项目方面的地缘政治优势,强调了两国之间的长期友谊以及持续合作所带来的互惠互利。第三章重点探讨了中国与塞拉利昂之间所形成的一种发展型合作关系以及有关案例分析的主要内容。这是在中国“一带一路”倡议的更广泛背景下进行的。换言之,这是为了提供社会经济发展的一种新的双赢模式,同时这将会涉及到在跨境地区的关键基础设施建设及其一种交通连通性的改善。但是,来自第三世界的不同非洲国家,它们可能只受益于与中国外交合作的机会,无法享受跟中国发展合作的一种新的时代性机遇。换句话说,从结果上看,其他非洲国家跟中国的发展合作情况是截然不同的。也就是说,就中国和塞拉利昂之间的跨区域发展合作而言,它对两国及其他非洲邻国也具有深远的启发或影响。在这样的现实背景下,作为一种较好的榜样,本文集中讨论了中国对塞拉利昂的积极影响及其对非洲地区发展合作的一种新的双赢模式。在第四章中,文章试图阐明弗里敦如何在中塞跨区域发展合作的大背景下转变为吸引外国游客的旅游城市之一。众所周知,作为塞拉利昂的首都和交通中心,弗里敦是位于非洲西北海岸地区的一座城市的。针对这些,本文还讨论了旅游产业的巨大发展潜力,及其呈现出逐渐增长趋势的海外投资。与此同时,从不同的角度看,这还涉及到其他的考虑因素。譬如,在弗里敦的转型方面,值得考虑一系列的环境因素、社会动态和政策实施过程中遇到的许多其他挑战和不同目标。这部分从塞拉利昂作为外国游客旅游目的地的潜力以及政府为其经济引入外国投资的动力开始。客观地说,尽管面临埃博拉疫情、油价下跌、铁矿石价格下跌等诸多挑战,塞拉利昂旅游业仍在快速复苏,通过抓取新的收入来源和注重绿色旅游。此外,值得注意的是,它还涵盖保护自然和历史资产。正因如此,从军事基地到旅游城市的一种历史性转型经验,可以理解为前所未有的一种尝试,以改变旧式发展战略,采用全新的战略来促进非洲国家的一种旅游导向型发展路线。它还计划扩大经济,并在有效的政策工具方面确保新的塞拉利昂政府的税收来源和财政收入。同时不可忽略的是,从塞拉利昂国内社会的视角看,这还包括其保护文化遗产的不懈努力。然而,在向旅游热点转型方面,塞拉利昂也有其自身的种种问题,譬如,基础设施仍然不足、外国游客费用高昂以及缺乏在旅游

Convolutional neural networks (CNNs) are widely used in image classification tasks, but their increasing model size and computation make them challenging to implement on embedded systems with constrained hardware resources. To address this issue, the MobileNetV1 network was developed, which employs depthwise convolution to reduce network complexity. MobileNetV1 employs a stride of 2 in several convolutional layers to decrease the spatial resolution of feature maps, thereby lowering computational costs. However, this stride setting can lead to a loss of spatial information, particularly affecting the detection and representation of smaller objects or finer details in images. To maintain the trade-off between complexity and model performance, a lightweight convolutional neural network with hierarchical multi-scale feature fusion based on the MobileNetV1 network is proposed. The network consists of two main subnetworks. The first subnetwork uses a depthwise dilated separable convolution (DDSC) layer to learn imaging features with fewer parameters, which results in a lightweight and computationally inexpensive network. Furthermore, depthwise dilated convolution in DDSC layer effectively expands the field of view of filters, allowing them to incorporate a larger context. The second subnetwork is a hierarchical multi-scale feature fusion (HMFF) module that uses parallel multi-resolution branches architecture to process the input feature map in order to extract the multi-scale feature information of the input image. Experimental results on the CIFAR-10, Malaria, and KvasirV1 datasets demonstrate that the proposed method is efficient, reducing the network parameters and computational cost by 65.02% and 39.78%, respectively, while maintaining the network performance compared to the MobileNetV1 baseline.

This study assessed the contribution of climate projections to improving rainfall information for cocoa crops in the central and southern regions of Côte d’Ivoire. Particular attention was paid to fourteen localities in these two climatic zones. Simulation data were obtained from the CORDEX ensemble and observation data from CHIRPS. They cover the period 1991-2005 for the reference period and the future period from 2021 to 2050 for the RCP4.5 and RCP8.5 scenarios. In addition, the study was based on the water requirements necessary during the critical phase of the cocoa tree (the flowering phase) for a good yield from the cocoa production chain on the one hand, and on a selection of three climate indices CDD, CWD and r95PTOT to study their spatio-temporal changes over two future periods 2021-2035 (near future) and 2036-2050 (medium-term) on the other. These climatic indices influence cocoa cultivation and their use in studies of climatic impacts on agriculture is of prime importance. The analysis of their spatio-temporal changes in this work also contributes to providing climate services based on rainfall, to which cocoa crops are highly sensitive. Our results show that the CDD and CWD indices vary from one region to another depending on latitude. For the fourteen localities studied, the number of consecutive dry days (CDD) could increase between now and 2050, while the number of consecutive wet days (CWD) could decrease over the period 2021-2035 and then increase over the period 2036-2050. The localities of Tabou, Aboisso and San-Pedro record high numbers of CDD index and CWD index for both projection scenarios. In comparison with the RCP4.5 and RCP8.5 scenarios, these results show that the RCP8.5 scenarios are having an impact on cocoa growing in Côte d’Ivoire.

Mango tilapia, Sarotherodon galilaeus is one of the most caught fish species in the Samandeni multi-species fishing sites of which, few data on its biology and exploitation are available. The study aimed to Assess the stock status of S. galilaeus. Sampling was conducted from March, 2021 to February 2022 based on commercial fish catches to analyze growth parameters, first sexual maturity size and harvest status of the stock. A total of 572 specimens including 297 females and 275 males were examined. The stock assessment was performed by using the length based Bayesian method of Biomass (LBB) and that of growth by the EleFAN method. The growth parameters showed a seasonality of growth and females appeared to grow faster than males. On the other hand, males had a greater asymptotic length than females. Results on the estimated length of fish at first maturity showed that females firstly reached the maturity compared to males. The relative biomass (B/B0) estimated for the stock was higher than the relative biomass that produces maximum sustainable yield (BMSY/B0) indicating healthy biomass. In addition, the length at first sexual maturity was less than the length at the first catch, indicating the absence of overfishing of growth. In addition, extending the study to the various stocks of the reservoir would be important for the sustainable management of the Samandeni high economic fishing area.

This study assesses the projected changes in the climate zoning of Côte d’Ivoire using the hierarchical classification of principal components (HCPC) method applied to the daily precipitation data of an ensemble of 14 CORDEX-AFRICA simulations under RCP4.5 and RCP8.5 scenarios. The results indicate the existence of three climate zones in Côte d’Ivoire (the coastal, the centre and the north) over the historical period (1981-2005). Moreover, CORDEX simulations project an extension of the surface area of drier climatic zones while a reduction of wetter zones, associated with the appearance of an intermediate climate zone with surface area varying from 77,560 km2 to 134,960 km2 depending on the period and the scenario. These results highlight the potential impacts of climate change on the delimitation of the climate zones of Côte d’Ivoire under the greenhouse gas emission scenarios. Thus, there is a reduction in the surface areas suitable for the production of cash crops such as cocoa and coffee. This could hinder the country’s economy and development, mainly based on these cash crops.
