第一次看到vivianeSassen的时候，我还在英国念书——摄影专业研究生，同班同学Mar tin兴致勃勃地邀请我一起去英国摄影师画廊（The Photographer’s Gallery）参加viviane Sassen的新书签售会和讲座，那是我第一次看到她的作品以及她本人。相信所有看过她作品的人，都会对其像花朵般鲜艳跳跃的颜色、像怪异生物般难以理解的肢体、以及黑得足以吸进所有事物的身体局部和阴影所着迷，它唤醒了我的回忆——在一个热烈的夏季夜晚，在去学校的路上，一位非裔留学生穿着极其鲜艳的彩色服装路过我的身边，那个与我差异巨大的肤色，渐渐融入了黑夜……这给我巨大的冲击。这个回忆让我共情了viviane Sassen的经历，她在2-5岁时随医生父亲来到了肯尼亚，非洲的刺眼阳光与神秘草原，对她而言“像家但我知道自己永远不会成为那个社会的一部分”的地方，以及在家庭的对谈中常常出现的伤痛、肢体，成为了她作品中一直不断探讨的主题。今年6月份，viviane Sassen首次造访中国，带着十几个不同系列近200余件作品，在Fotografiska影像艺术中心举办了她的首个大型回顾展——《磷光体：艺术&时尚1990-2023》，“就像清空了衣柜一样”，她又可以在她巨大的幻想世界里，继续肆意地填充新的衣服了。

Soil Organic Carbon Stock Variation under Different Soil Types and Land Uses in the Sub-Humid Noun Plain, Western Cameroon

Open Journal of Soil Science 2024年第4期14卷 191-209页

作者： Frank Abigail Sobze Kenfack Georges Kogge Kome Achille Bienvenue Ibrahim viviane Pauline Mandah Dieudonne Bitondo Department of Soil Science Faculty of Agronomy and Agricultural Sciences (FASA) University of Dschang Dschang Cameroon Department of Land Surveying National Advanced School of Public Works Yaound&#233 Cameroon International Institute of Tropical Agriculture Cameroon Eco-Regional Center HFS Yaound&#233 Cameroon Department of Earth Science Faculty of Science University of Dschang Dschang Cameroon

This study was conducted to assess the current stock of soil organic carbon under different agricultural land uses, soil types and soil depths in the Noun plain in western Cameroon. Three sites were selected for the study, namely Mangoum, Makeka and Fossang, representative of the three dominant soil types of the noun plain (Andosols, Acrisols and Ferralsols). Three land uses were selected per site including natural vegetation, agroforest and crop field. Soil was sampled at three depths;0 - 20 cm, 20 - 40 cm, and 40 - 60 cm. Analysis of variance showed that soil type did not significantly influence carbon storage, but rather land uses and soil depth. SOCS decreased significantly with depth in all the sites, with an average stock of 66.3 ± 15.8 tC/ha at 0 - 20 cm, compared to an average stock of 33.3 ± 7.4 tC/ha at 40 - 60 cm. SOCS was significantly highest in the natural formation with 57.2 ± 19.7 tC/ha, and lowest in cultivated fields, at 37.7 ± 10.6 tC/ha. Andosols, with their high content of coarse fragments, stored less organic carbon than Ferralsols and Acrisols.

Economic Stress, Precariousness and Risk of High Blood Pressure: A Descriptive Survey of Life Models within Households of the Central Region of Cameroon

作者： Jean Ndibi Abanda Ulrich Dama viviane Foussouo Ndoungue Anicet Onana Akoa Melkior Fobasso Dzeuta Alphonse Tedonge Asobochia Arsène Emilien Messi Ndzengue Désiré Tchoffo Faculty of Health Sciences University of Lisala (CIREP-UNILIS) Lisala Democratic Republic of the Congo National Order of Medical and Sanitary Professions Yaoundé Cameroon School of Health Sciences Catholic University of Central Africa Yaoundé Cameroon World Health Organization Maroua Cameroon Faculty of Health Sciences University of Montagnes Banganté Cameroun Faculty of Medicine University of Bamenda Bamenda Cameroon Faculty of Sciences University of Ebolowa Ebolowa Cameroun

Context/Objective: High blood pressure (HBP) currently represents the most widespread chronic non-communicable disease in Cameroon. The increase in its prevalence in the country is the result of multiple factors including economic stress imposed by precariousness, poor living conditions, sources of anxiety, anguish, depression and other behavioral disorders. Economic stress is a globalizing concept that integrates into a purely hermeneutic approach, a particular functioning of the nervous system of an individual who faces employment problems and precarious remuneration conditions. The non-satisfaction by an individual of his basic needs due to insufficient financial means can cause him to become irritable, aggressive, and socially and symbolically isolated, thereby increasing the desire to resort to morbid life models such as excessive consumption of narcotics and other psychoactive substances often associated with high blood pressure. The fight against the emergence of BPH is a complex, multifaceted and multifactorial reality that requires taking into account economic stress. The main objective of this survey is to describe the situation of economic stress within the Cameroonian population, which imposes precariousness and life models at risk of high blood pressure. Specifically, we determined the level of household income and the sources of income. Methods: A cross-sectional survey with a descriptive aim among five hundred households in the Central Region of Cameroon was conducted. A probabilistic technique called simple randomness was used. The number of households to be surveyed was determined indirectly using the Cochrane formula. Data collection in face-to-face mode using a physical questionnaire took place from July 1 to August 31, 2023, after obtaining ethical clearance from the Regional Health Research Ethics Committee, Human from the Center and an administrative authorization for data collection. Regarding their processing, the data was grouped during proc

Prevalence of Latent Tuberculosis Infection [LTBI] in Prison Officers: A Systematic Review and Meta-Analysis

Open Journal of Respiratory Diseases 2024年第1期14卷 12-24页

作者： Thiago Poss Moreira Gustavo Henrique Baraca Sanvezzo Maico Trevisol Renan William Mesquita Luiza Scalcon de Oliveira Lia Beatriz Henke de Azevedo Cleide viviane Buzanello Martins Lirane Elize Defante Ferreto Health Sciences Center Faculty of Medicine Western Paraná State University Francisco Beltr&#227o Brazil Health Sciences Center Postgraduate Program in Applied Health Sciences Western Paraná State University Francisco Beltr&#227o Brazil

This study aimed to perform a systematic review and meta-analysis to determine the LTBI prevalence in prison officers worldwide. A systematic search was performed in PubMed, WoS, Embase, and BVS, including all articles related to LTBI prevalence and risk factors. After critical evaluation and qualitative synthesis of the identified articles, a meta-analysis was used. Five studies carried out between 2012 and 2022 were included, with a total sample size of 1718 prison officers. The overall LTBI prevalence was 50% [95% confidence interval [CI]: 48% - 52%;n = 816], with high heterogeneity between studies. Smoking [OR = 1.76;CI 95% = 1.26 - 2.46] and males [OR = 2.08;CI 95% = 1.31 - 3.31] were positively related to a higher LTBI prevalence among prison officers. Thus, preventive measures and the rapid and accurate diagnosis of new cases should be emphasized to ensure tuberculosis control, especially among risk groups such as prison officers.

作者： Rémi Abgrall Maria Han veiga University of Zurich ZurichSwitzerland University of Michigan Ann ArborUSA

Recent works have shown that neural networks are promising parameter-free limiters for a variety of numerical schemes(Morgan et *** A machine learning approach for detect-ing shocks with high-order hydrodynamic *** *** J Comput Phys 367:166-191.,2018;veiga et *** European Conference on Computational Mechanics andⅦEuropean Conference on Computational Fluid Dynamics,vol.1,***.,2018).Following this trend,we train a neural network to serve as a shock-indicator function using simulation data from a Runge-Kutta discontinuous Galer-kin(RKDG)method and a modal high-order limiter(Krivodonova in J Comput Phys 226:879-896.,2007).With this methodology,we obtain one-and two-dimensional black-box shock-indicators which are then coupled to a standard ***,we describe a strategy to transfer the shock-indicator to a residual distribution(RD)scheme without the need for a full training cycle and large data-set,by finding a mapping between the solution feature spaces from an RD scheme to an RKDG scheme,both in one-and two-dimensional problems,and on Cartesian and unstruc-tured *** report on the quality of the numerical solutions when using the neural network shock-indicator coupled to a limiter,comparing its performance to traditional lim-iters,for both RKDG and RD schemes.
