This work presents a method of optimization of the photovoltaic generator (PV) based on the electrical model with a diode. The method consists of solving a second degree equation representing the derivative of the power function. The current and the maximum voltage being determined, the maximum power is deduced. Four popular types of photovoltaic panels from different manufacturers were considered for the study: BYD Model (BYD 320P6C-36), Atersa Grupo Model (A-320P GSE), SunPower Model (E19-320) and Model operated in the 50 MW power plant of Nouakchott-Mauritania (JKM320PP-72-V) of JinkoSolar. A comparative study is carried out between the simulated results and the data of the manufacturer of different technologies. The results obtained prove the effectiveness of the proposed method and that the BYD 320P6C-36 model is the most efficient among the four different technologies studied.

本文通过泰尔指数、向量自回归(VAR)模型等刻画长江经济带跨界污染排放对区域经济增长的影响。结果表明:在样本区间2005-2020年间,长江经济带九省二市污染排放总体呈波动下降的趋势,但存在显著的空间差异;VAR模型显示长江经济带污染排放量的变化无法缩小污染排放差异,而污染排放差异的变化则会降低污染排放量;经济增长对污染排放有抑制作用,而污染排放并不会推动经济的增长,反而呈现出一定的负向效应;长江经济带污染排放差异与经济增长表现出微弱的相关性。因此,应进行科学有序开发,建立长效保护机制,在控制排放总量的同时注意消除区域差异,将短期效益与长期愿景相结合,探索因地制宜的环境规制措施,以此来推动长江经济带跨界水污染的协同治理。

Introduction: Birth spacing to prevent closely-spaced pregnancies, which are a source of maternal and neonatal morbidity and mortality, is not always respected by our women, as recommended by the World Health Organization (WHO). The objective was to study the factors associated with closely-spaced pregnancies among women followed at the Departmental Hospital Center du Zou et du Colline (DHC/Z-C) in 2022. Study Method: This was a descriptive, analytical cross-sectional study with prospective data collection from 20 May to 30 June 2022. Results: At the end of the study, 83 of the 117 women surveyed had close pregnancies, a frequency of 70.94%. They had an average age of 27.0 ± 6.3 years and were of Fon ethnicity and related in 91.57% of cases. The majority were married (96.60%). The factors significantly associated with these closely spaced pregnancies were age between 25 and 30 years, household occupation, age at first birth, age at marriage, women’s perception of contraceptive method (CM), women’s knowledge of the existence of a center providing family planning services and non-use of MC. Conclusion: Close pregnancies are still very common in the commune of Abomey. It is therefore important to increase the use of contraceptive methods in this part of the country.

针对预应力耗能(PTED)钢框架结构的连续倒塌问题,采用ABAQUS软件建立精细化有限元模型,对框架结构拆除承重构件后不平衡荷载重分配的行为展开研究。并将有限元结果与1/3缩尺PTED钢框架的准静态试验结果进行对比分析,验证了模型的准确性。在此基础上,进一步开展了PTED钢框架抗连续倒塌受力机制的研究,并分析了初始预应力、预应力钢绞线数量、钢构件材料强度和梁翼缘宽厚比四种因素对钢框架抗连续倒塌机制的影响。结果表明:PTED钢框架抗连续倒塌过程主要包括三个阶段:初始阶段、压拱机制有利阶段和压拱机制不利阶段;倒塌抗力由预应力钢绞线拉力和梁柱之间的竖向作用力共同提供;提高初始预应力、预应力钢绞线数量、钢材屈服强度和降低梁翼缘宽厚比,均会使峰值荷载增大;钢绞线数量的增多使框架在失效柱位移较小时可以提供较大的抗力;增强梁柱构件抵抗局部屈曲变形的能力会提升预应力钢框架抗连续倒塌能力。

教育为一定的人口服务，在全国面临“负增长、低生育、老龄化、高流动”的人口发展新形势下，为应对人口变化对吉林省职业教育发展的挑战，基于吉林省人口规模结构现状对2025-2050年职业教育学龄人口进行预测，对吉林省职业教育的学校、学生、师资配备及区域分布情况等进行系统梳理，结果显示：吉林省总人口呈现逐步减少趋势；老龄化人口比例逐步升高，逐步进入深度老龄化阶段；人口低生育化，出生人口持续减少；城镇化率缓慢，农村人口减少；人口向中心城市集聚；人口受教育程度不断提升。吉林省职业教育资源呈现中等职业教育发展持续下降、高等职业教育发展快速增长、成人教育发展不足等趋势。在人口发展新形势下，吉林省职业教育发展面临生源危机、资源配置、城乡均衡发展、继续教育供需失衡等挑战。基于此，吉林省职业教育实现高质量发展，要建立动态监测机制、优化教育资源配置、深化教育教学改革、加快发展继续教育。

Introduction: Malnutrition is a major public health problem in Mali, despite the efforts of the government, its technical and financial partners. The aim of this study was to evaluate the integrated management program for acute malnutrition (IMPAM). Methodology: This was a descriptive cross-sectional study that took place from January to December 2020 in the Douentza health district. The study included anyone with at least one malnourished child aged 6 to 59 months in their care who agreed to take part in the study, community health center staff who had given their consent, and the URENI manager at the Douentza reference health center. Data collected via questionnaires were entered into Excel and then analyzed using Epi-Info version 7 software. Results: A total of 138 acutely malnourished children aged 6 - 59 months, including 71 girls (51.45%), 138 accompanying mothers and 11 health workers, were included in our case study. Among the malnourished, 54.34% were in the 12 - 23 months age group and 69.57% had the severe form. 93% of the mothers interviewed were satisfied with the care provided, and all the health staff interviewed stated that community conflicts had an impact on IMPAM’s activities. Cure rates were 81% in Moderate Outpatient Nutritional Recovery and Education Unit (URENAM), 84% in Severe Ambulatory Nutritional Recovery and Education Unit (URENAS) and 92% in Recovery and Intensive Nutritional Education Unit (URENI). Drop-out rates were 19% in URENAM, 16% in URENAS and 0% in URENI. The death rate was 8% in URENI and 0% in URENAM and URENAS. Conclusion: This study confirms the high prevalence of malnutrition in the district (10.54%). It also reveals that factors such as inter-community conflict and insecurity have seriously affected the IMPAM program.
