Abstract Gender equality and women’s empowerment are major concerns under Goal 5 of the United Nations' Sustainable Development Goals to be achieved by 2030. Therefore, microfinance institutions in developing nations have been working on these issues by providing loans to married women and others in need. As a result, this paper focuses on one such microfinance institution in Ethiopia, called ACSI (Amhara Credit and Saving Institution), and its role in fostering economic independence for married women and their involvement in various public social schemes. The study utilized a qualitative approach, collecting data through in-depth interviews (26), focus group discussions (1), and life histories from ACSI experts (4) and key informants from Women's and Children's Affairs (6). Specifically, the study focused on married women in Basona Werana Woreda and examined the impact of ACSI's credit services on their social conditions. The empirical findings of the study reveal that the social condition of married women clients has improved due to the credit services provided by ACSI. Women's social empowerment indicators have shown positive changes after utilizing the credit services. However, the study also identified challenges faced by the institution, such as a lack of adequate transportation means and a shortage of personnel to reach remote residents and fulfill their mission of improving the situation of vulnerable low-income and productive poor resident women. Additionally, cultural attitudes pose significant challenges to the social empowerment of women. The empirical implementation of this study provides insights into the achievements and hurdles that need to be addressed in enhancing economic security for married women through microfinance initiatives.
性别平等和妇女赋权是联合国2030年可持续发展目标5的主要关注点。因此,发展中国家的小额信贷机构一直致力于解决这些问题,向已婚妇女和其他有需要的人提供贷款。因此,本文将重点放在埃塞俄比亚的一个这样的小额信贷机构,称为ACSI(阿姆哈拉信贷和储蓄机构),以及它在促进已婚妇女经济独立和她们参与各种公共社会计划方面的作用。该研究采用了定性方法,通过深度访谈(26)、焦点小组讨论(1)和ACSI专家(4)和妇女儿童事务关键线人(6)的生活史收集数据。具体而言,该研究侧重于Basona Werana Woreda的已婚妇女,并检查了ACSI的信贷服务对其社会状况的影响。研究的实证结果显示,已婚女性客户的社会状况因ACSI提供的信贷服务而有所改善。利用信贷服务后,妇女社会赋权指标出现积极变化。然而,该研究也确定了该机构面临的挑战,例如缺乏足够的交通工具和人员短缺,无法接触到偏远地区的居民并履行其改善脆弱的低收入和生产性贫穷居民妇女状况的使命。此外,文化态度对赋予妇女社会权力构成重大挑战。本研究的实证实施提供了通过小额信贷举措加强已婚妇女经济安全方面需要解决的成就和障碍的见解。

Prospects for hydrogen fuel cell vehicles to decarbonize road transport 氢燃料电池汽车脱碳道路运输的前景

Abstract This paper explores the role of hydrogen fuel cell vehicles (HFCVs) in helping to meet global climate goals of limiting long-term greenhouse gas (GHG) emissions to 1.5 °C. Employing the GREET Model and data from the International Energy Agency (IEA), the study comprehensively compares the full fuel-cycle emission profiles of HFCVs and battery electric vehicles (BEVs). The paper conducts an in-depth examination of the interplay between the carbon intensity of the electric grid and the resulting GHG emissions within the context of refueling HFCV vehicles via electrolyzers, and the analysis draws a comparison to BEVs charged using the same electric grid. The study finds that while emissions for BEVs increase, emissions for HFCVs are significantly larger when HFCVs are refueled from retail outlets producing hydrogen via electrolysis from grid electricity—a finding that was not previously reached in the current literature. The research underscores that countries operating electric grids characterized by high GHG emissions or lacking robust pathways to emission reduction would face suboptimal outcomes by adopting HFCVs powered by hydrogen sourced from distributed grid electricity generation. The gCO2e/mi for BEVs and HFCVs are also calculated when the electricity is produced from renewable energy resources. When electricity is derived from renewable energy sources, it becomes evident that the gCO2e/mi for both HFCVs and BEVs converge towards ‘zero’. The emission metric of gCO2e/mile for a HFCV refueled with the hydrogen produced from natural gas via steam methane reforming (SMR) without carbon capture utilization and storage (CCUS), stands at 105 gCO2e/mile, whereas in the absence of CCUS, it escalates notably to 247 gCO2e/mile, an approximate 150% increase in stark contrast to CCUS inclusion. This quantitative portrayal serves to underscore the substantial potential for curtailing carbon footprints achievable through the integration of CCUS, thereby amplifying its significance within the realm of hydrogen-based transportation and the broader purview of climate change mitigation endeavors. In order to provide a comprehensive perspective, the study delves into the examination of hydrogen production pathways and associated costs for the years 2021, 2030, and 2050. The forecasted supply costs are elucidated, particularly in relation to the potential hydrogen supply originating from variable renewable energy (solar PV and wind) sources and from CCUS-equipped hydrogen production facilities (considering the project pipeline of projects upto 2030). These factors are of substantial importance in shaping the hydrogen supply landscape and subsequently influencing the adoption of HFCVs in the market. The study also examines the cost implications of hydrogen delivery for varying transportation distances (for 2030), acknowledging their important role in the broader context. The challenges posed by the integration of variable renewable energy sources are al
摘要:本文探讨了氢燃料电池汽车(HFCVs)在帮助实现将长期温室气体(GHG)排放限制在1.5°C的全球气候目标中的作用。该研究采用GREET模型和国际能源署(IEA)的数据,全面比较了氢燃料电池汽车和纯电动汽车(bev)的全燃料循环排放曲线。本文深入研究了在通过电解槽为氢燃料电池汽车加油的情况下,电网碳强度与由此产生的温室气体排放之间的相互作用,并将其与使用相同电网充电的纯电动汽车进行了比较。研究发现,虽然纯电动汽车的排放量增加了,但当氢燃料汽车从零售店通过电网电力电解生产氢气时,氢燃料汽车的排放量会显著增加——这是目前文献中尚未发现的一项发现。该研究强调,运营以高温室气体排放为特征的电网或缺乏强有力的减排途径的国家,如果采用由分布式电网发电的氢动力氢燃料汽车,将面临次优结果。当电力来自可再生能源时,也计算了纯电动汽车和氢燃料电池汽车的gCO2e/mi。当电力来自可再生能源时,氢燃料电池汽车和纯电动汽车的gCO2e/mi明显趋近于“零”。以天然气蒸汽甲烷重整(SMR)生产的氢气为燃料的氢燃料汽车,在没有碳捕集利用和封存(CCUS)的情况下,每英里二氧化碳当量的排放指标为105克二氧化碳当量,而在没有CCUS的情况下,二氧化碳当量显著上升至247克二氧化碳当量/英里,与加入CCUS形成鲜明对比,增加了约150%。这一定量描述强调了通过整合CCUS可实现的减少碳足迹的巨大潜力,从而扩大了其在氢基运输领域和更广泛的减缓气候变化努力范围内的重要性。为了提供一个全面的视角,该研究深入研究了2021年、2030年和2050年的制氢途径和相关成本。预测的供应成本被阐明,特别是与来自可变可再生能源(太阳能光伏和风能)来源和配备ccus的氢气生产设施的潜在氢气供应有关(考虑到2030年的项目管道)。这些因素在塑造氢供应格局并随后影响氢燃料电池汽车在市场上的采用方面非常重要。该研究还考察了不同运输距离(2030年)氢气输送的成本影响,承认它们在更广泛的背景下的重要作用。此外,还讨论了可变可再生能源整合带来的挑战,以及有效储能解决方案的必要性。这一论述在能源转型的总体框架内展开,其显著特征是太阳能光伏和风能的优势。这些方面错综复杂的相互作用在塑造未来中长期氢供应动态的轨迹中起着关键作用。

Abstract The United Nations' (UN) Sustainable Development Goals (SDG) are a recognised metric for measuring environmental, economic, and societal progress. However, national or multinational-level analyses are more prevalent than sub-national types. The performance of 14 SDGs for 56 Indian cities (grouped into 6 regions) with the available 77 indicators (2020–2021) have been analysed. Pearson’s correlation, hierarchical clustering, data envelopment analysis, Theil index, etc. were used to infer existing status, interactions, inequality, efficiency, and interrelationships. Finally, policy suggestions have been offered coupled with limitations to mitigate the drawbacks of the Indian city SDG framework. The findings reveal the asynchronous nature of the SDGs. 18% of Indian cities register a poor track record of converting environmental performance into socioeconomic prosperity, while 55% of cities are lagging in performance compared to their respective states. Significant inequality exists among cities in various regions towards achieving the SDGs. The environment is adversely affected in a race to be economically powerful. So, mainstreaming the environment into development planning is urgently warranted.
联合国(UN)可持续发展目标(SDG)是衡量环境、经济和社会进步的公认指标。然而,国家或跨国层面的分析比次国家类型更为普遍。对56个印度城市(分为6个地区)的14个可持续发展目标的表现进行了分析,并提供了77个指标(2020-2021年)。运用Pearson’s correlation、分层聚类、数据包络分析、Theil index等方法推断现有状态、相互作用、不平等、效率和相互关系。最后,提出了政策建议,并结合局限性,以减轻印度城市可持续发展目标框架的缺点。研究结果揭示了可持续发展目标的不同步性质。18%的印度城市在将环境绩效转化为社会经济繁荣方面表现不佳,55%的城市在表现上落后于各自所在的邦。不同地区的城市在实现可持续发展目标方面存在显著不平等。在经济实力的竞争中,环境受到了不利影响。因此,迫切需要将环境问题纳入发展规划的主流。

Abstract This study investigates the influence of tip speed ratio (TSR) as maximum power point tracking (MPPT) technique on energy conversion for wind-powered electric vehicles (EVs) charging stations. The data for 14 different models of (EVs) as well as the energy demand profile for El Sherouk city in new Cairo, Egypt, is used in the study. Those vehicles represent the models that are most likely to be used according to the nature of the Egyptian market from economic and technological concerns. This includes range, battery capacity, battery technology and charging methods. charging can be in the form of fast DC, three phases which are suitable for commercial charging stations or a single phase charging suitable for residential use. A simulation is done using MATLAB/Simulink for a wind turbine Permanent Magnet Synchronous Generator (PMSG) system including TSR MPPT algorithm. The energy output is compared with and without implementing the MPPT algorithms to measure the difference in energy. The system simulation optimized by the TSR MPPT algorithm shows an increase in the energy yield by 41.68%. The economic analysis showed a 30% reduction in the levelized cost of energy while utilizing the TSR concerning a bare system without an MPPT algorithm.
摘要研究了尖顶速比(TSR)作为最大功率点跟踪(MPPT)技术对风电电动汽车充电站能量转换的影响。该研究使用了14种不同车型(电动汽车)的数据以及埃及新开罗El Sherouk市的能源需求概况。从经济和技术方面考虑,根据埃及市场的性质,这些车辆代表了最有可能使用的车型。这包括续航里程、电池容量、电池技术和充电方法。充电形式可以是快速直流,三相,适用于商业充电站或单相充电,适用于住宅使用。利用MATLAB/Simulink对采用TSR MPPT算法的风力发电永磁同步发电机(PMSG)系统进行了仿真。比较了使用和不使用MPPT算法时的能量输出,以测量能量差。采用TSR MPPT算法优化的系统仿真结果表明,系统的发电量提高了41.68%。经济分析表明,在没有MPPT算法的裸系统中,使用TSR可以降低30%的能源平准化成本。

Abstract Methylene blue (MB) is commonly a persistent and perilous pollutant in industrial wastewater effluent. While MB has a massive negative effect on human and ecology safety. The neutralization of such harmful material would save a huge clean water amount. This work proposes the natural and abundant black sand as a catalyst for MB photodegradation. The sand sample was calcined at three temperatures of 300°, 400°, and 600 °C. The properties of samples were analyzed with different micro- as well as spectroscopic techniques. The experimental data revealed the sample's main composition of SiO 2 , Fe 2 O 3 , and Al 2 O 3 . XRD and XPS results proved the formation of mixed oxides composites due to calcination, especially at 400 °C. The UV– vis analysis conducted showed that samples can absorb light in the visible range. The photodegradation reached a maximum of 975.3%, 82.7%, and 75.7% for BS 400 , BS 600 , and BS 300 respectively; by illumination for 2.5 h in the visible range. The observed distinguishable catalytic performance was discussed via the spectroscopic analysis and oxygen availability in the catalyst lattice. When AO, t-BuOH, and BQ are used as scavengers instead of just BQ during the photodegradation of MB dye over BS 400 catalyst, the photodegradation rate drops significantly. The degradation % of MB dye diminished to 60%, and 70% by using AO, t-BuOH, and BQ scavengers; respectively. This proved that rather than hydroxyl radicals, superoxide radicals or positive hole production is the main determining step in MB photo-degradation over BS 400 catalyst.
亚甲基蓝(MB)是工业废水中常见的持久性有害污染物。而MB对人类和生态安全有着巨大的负面影响。这些有害物质的中和将节省大量的清洁水。本研究提出了天然丰富的黑砂作为光降解MB的催化剂。砂样在300°、400°和600°C三种温度下煅烧。用不同的显微和光谱技术分析了样品的性质。实验数据表明,样品的主要成分为sio2、fe2o3和al2o3。XRD和XPS结果表明,在400℃时煅烧形成了混合氧化物复合材料。紫外可见分析表明,样品能吸收可见光范围内的光。bs400、bs600和bs300的最大光降解率分别为975.3%、82.7%和75.7%;在可见光范围内照明2.5小时。通过光谱分析和催化剂晶格中的氧可用性讨论了所观察到的可区分的催化性能。在bs400催化剂上光降解MB染料时,用AO、t-BuOH和BQ代替BQ作为清除剂,光降解率明显下降。AO、t-BuOH和BQ对MB染料的降解率分别降至60%和70%;分别。这证明,在bs400催化剂上,超氧自由基或正空穴的产生是MB光降解的主要决定步骤,而不是羟基自由基。
