The utility idea is used to optimize AISI M7 hard turning in the present study. This study uses the Taguchi optimization approach to examine the effects of insert nose radius and machining parameters such as cutting speed, feed rate, and depth of cut on surface roughness (Ra) and material removal rate (MRR) in a turning operation. The signal-to-noise (S/N) ratio is used to analyze the performance characteristics in the turning of AISI M7 employing nose radius of 0.4, 0.8, and 1.2 mm carbide inserts on CNC turning centre in a three-level, four-parameter design of experiment using L9 orthogonal array using MINITAB 17. Every trial is held in a dry setting. According to the results of the current investigation, feed rate and nose radius are the most important variables affecting surface roughness and material removal rate.
本文采用效用思想对aisim7硬车削进行优化。本研究采用田口优化方法,考察了车削加工中切削速度、进给速度和切削深度等切削参数对表面粗糙度(Ra)和材料去除率(MRR)的影响。采用信噪比(S/N)方法,利用MINITAB 17软件,采用L9正交阵列进行三水平四参数实验设计,分析了切削齿径为0.4、0.8和1.2 mm的AISI M7刀具在数控车削中心车削时的性能特征。每次审判都在干燥的环境中进行。根据目前的研究结果,进给量和机头半径是影响表面粗糙度和材料去除率的最重要变量。

The basic right of people in any society is earning a livelihood, and providing or fulfilling this requirement is a prime duty of the concerned government. Acting towards this end the democratic government of Ethiopia (African continent) has recently launched a resettlement program. The main objective of this study is to provide an overall view of the resettlement program in Bamluk and Sawatamp settlement sites, Jawi district, Amhara Regional State of Ethiopia. A qualitative method of analysis was employed for conducting this study. The informants at the household level were randomly selected to give the possible representative information. Key informants interviews and focus group discussions with resettlers and government representatives at district and zonal levels were held. The study revealed that there is a gap between the program document and its implementation on the ground. There was no consistency with the pillars, key principles, and approaches in the program document. The resettlement’s adverse consequences were the lack of proper preparation. The study indicates that the establishment of infrastructure and social services before the resettlement program are below the minimum standard and the services have not yet been improved in the area. Moreover, small land holdings and the risk of exposure to malaria contributed to the failure of the program. This reveals that the implementation of the resettlement program in the area is very weak.
在任何社会中,人们的基本权利都是谋生,提供或实现这一要求是有关政府的首要职责。为此目的,埃塞俄比亚(非洲大陆)民主政府最近启动了一项重新安置方案。本研究的主要目的是全面了解埃塞俄比亚阿姆哈拉州贾维和巴姆鲁克和萨瓦坦普定居点的安置方案。本研究采用定性分析方法。随机选择家庭一级的举报人提供可能具有代表性的信息。在地区和区域各级与重新安置者和政府代表进行了主要线人访谈和焦点小组讨论。研究显示,在方案文件和实际执行之间存在差距。与项目文件中的支柱、关键原则和方法不一致。重新安置的不利后果是缺乏适当的准备。研究表明,安置前的基础设施和社会服务建设低于最低标准,服务尚未得到改善。此外,土地面积小和容易感染疟疾也是导致该计划失败的原因之一。这表明,该地区移民安置方案的实施非常薄弱。

One of the greatest technological advancements in the last century lies in digital computer science. The idea of storing information and performing complicated calculations with the help of bits, i.e., 0 and 1. But due to a sudden surge in data, the classical computer system has been becoming weak in data processing. Quantum computers offer promising substantial speedup over classical computers for many applications. Quantum chip fabrication has made remarkable gains in recent years, with the number of qubits and fidelity growing. In general computing, a binary digit is the smallest unit of information or a bit. “In quantum computing, the term Qubit (Quantum Bit) serves the exact function of the term bit.” IBM Research released the IBMQ Experience in 2018, the first quantum computer that anyone can use and make accessible to a huge audience of different countries through cloud access. IBM also introduced the tool QISKIT (Quantum information software kit), which enables teachers, researchers, and developers to write coding and run their coding on quantum machines. It also includes different packages of quantum computing. In this paper, the author has discussed different steps to install qiskit. Mainly this paper focused on the “programming and application side of quantum computing.” Qiskit tools used in the python programming language. The “quantum circuits” are fabricated with the use of quantum gates and favorable algorithms with less execution time
上个世纪最伟大的技术进步之一是数字计算机科学。利用位(即0和1)来存储信息和进行复杂计算的思想。但是由于数据量的激增,传统的计算机系统在数据处理方面变得越来越弱。在许多应用中,量子计算机比传统计算机提供了有希望的大幅加速。近年来,随着量子比特的数量和保真度的增长,量子芯片制造取得了显著的进步。在一般计算中,二进制数字是最小的信息单位或位。“在量子计算中,术语Qubit(量子比特)的功能与术语Bit完全相同。”IBM研究院于2018年发布了IBMQ体验,这是第一台任何人都可以使用的量子计算机,并通过云访问向不同国家的大量受众开放。IBM还推出了QISKIT(量子信息软件套件)工具,使教师、研究人员和开发人员能够在量子机器上编写代码并运行他们的代码。它还包括不同的量子计算包。在本文中,作者讨论了安装qiskit的不同步骤。本文主要关注“量子计算的编程和应用方面”。Qiskit工具中使用的python编程语言。“量子电路”是利用量子门和具有较短执行时间的有利算法来制造的

Dioxin lignin of Eucalyptus tereticornis kraft pulps and its oxygen-treated pulps with kappa number 21.32, 12.84; 13.03, 12.18 were isolated and subjected to alkaline nitrobenzene oxidation studies to determine the structural changes during oxygen bleaching. HPLC quantitatively identified eight compounds during nitrobenzene oxidation of dioxin lignin in alkaline media. Lignin obtained from E. tereticornis has syringyl and guaiacyl units. Residual lignin composition in pulps was studied and found that during oxygen delignification, the syringyl unit was degraded more in comparison to guaiacyl and p-hydroxy phenyl unit, i.e., the molar ratio of syringyl unit is lower than guaiacyl and p-hydroxy phenyl unit. The results are adequately described in the research.

The broad objective of the study was to investigate the determinants of dairy market in Mizan-Aman town, Bench-Sheko zone, Ethiopia. For the purpose of the study, 228 sample households were selected from the town using a stratified random sampling technique and the field data were collected using questionnaires. The binary linear regression model analysis was employed to identify determinants that affect the dairy market. The model result showed that dairy market was strongly and significantly affected by use of improved feed, demand for milk, frequency of getting training, access for credit, and education of the household heads. Shortage of feed and seasonality of demand, particularly in fasting time are challenges of dairy marketing in the area. Dairy producers, retailers, farms, and cooperatives were found the main milk market channel of the study area. The dairy market in the study area uses an informal marketing system which shows the underdevelopment of dairy marketing. Thus, dairy development interventions should be aimed at addressing both dairy production technological gaps and marketing problems. Further, the study shows that there is a high demand for dairy products. Therefore, dairy processing industry’s establishment, support for dairy producers and improving access to services should receive due attention in order to improve dairy market in the study area by all dairy development stakeholders
该研究的主要目的是调查埃塞俄比亚Bench-Sheko地区Mizan-Aman镇乳制品市场的决定因素。本研究采用分层随机抽样的方法,从该乡镇抽取样本家庭228户,采用问卷调查的方式收集现场资料。采用二元线性回归模型分析来确定影响乳制品市场的决定因素。模型结果表明,乳制品市场受到改良饲料使用、牛奶需求、培训频率、信贷获取和户主教育程度的强烈而显著的影响。饲料短缺和季节性需求,特别是在禁食期间,是该地区乳制品营销面临的挑战。乳品生产者、零售商、农场和合作社是研究区乳品市场的主要渠道。研究区乳制品市场采用非正式的营销体系,显示了乳制品营销的不发达。因此,乳制品发展干预措施应着眼于解决乳制品生产技术差距和营销问题。此外,研究表明,人们对乳制品的需求很大。因此,乳制品加工业的建立、对乳制品生产者的支持和改善服务的可及性应得到所有乳制品发展利益相关者的应有重视,以改善研究区域的乳制品市场

One of the main reasons for Ethiopia’s declining agricultural production is land use change under poor soil management practices. Hence, in order to evaluate the effects of various land use types on certain soil qualities, research was done on the soils of Cheha district, Gurage zone in Ethiopia’s central highlands. Four different land use types (LUTs) (cultivated, enset, eucalyptus, and wild forest) were used for this study to assess and analyze their response to soil fertility. A total of 48 soil samples (24 undisturbed and 24 disturbed) was collected from the selected LUTs and two different soil depths (SDs) (0-20 and 20-40 cm) with three replications for the laboratory analysis. The results showed that most of the properties of soil physicochemical properties of soil were significantly affected by LUTs, SD, and the interactions. The result showed that the highest sand (43%), silt (46.5%), and clay (30.30%) fractions were observed under forest land (FL), enset farmland (ENFL), and cultivated land (CUL), respectively. Concerning the SD, higher silt (40.9%) and clay (28.3%) were found in the subsurface soils. Except for CUL, textural classes of all LUTs were loamy. The highest (1.37 g cm-3) bulk density was observed under the subsurface soils of CUL and the lowest (1.06 g cm-3) was in the surface soils of FL and ENFL. In contrast to bulk density, total porosity was highest (60.1%) under surface soils of FL and ENFL and the lowest (48.3%) value was observed under subsurface soils of CUL. The combination of two factors influenced the soil pH. The highest value (6.54) and lowermost (4.82) values were found under the surface soils of ENFL and subsoils of EUCL, respectively. Comparatively, the uppermost (7.48%) and lowermost (3.55%) values of organic matter were recorded under the surface soils of FL and subsoils of EUCL. The uppermost (0.37%) and lowermost (0.17%) values of total nitrogen were registered under surface soil and subsoils of FL and EUCL, respectively. The uppermost (22.69 mg kg-1) value of Av.P was registered under superficial soils of ENFL and the lowermost (5.02 mg kg-1) was obtained under a subsurface layer of EUCL. The uppermost (37.96 cmol(+) kg-1) and lowermost (11.90 cmol(+) kg-1) of CEC values were observed under the surface soils of FL and subsoils of EUCL. The uppermost value of exchangeable acidity (1.85 cmol(+) kg-1) was recorded under soils of EUCL. This study showed that different LUTs and SDs have substantial impacts on the status of soil fertility. Soils of FL and ENFLs were relatively more fertile. Increasing eucalyptus tree cover on arable land and intensive farming severely impacted soil fertility which may have increased soil acidity. Appropriate land use and a variety of soil fertility management practices are crucial to address soil fertility loss and acidity issues
埃塞俄比亚农业产量下降的主要原因之一是土壤管理不善导致的土地利用变化。因此,为了评估不同土地利用类型对土壤质量的影响,对埃塞俄比亚中部高原古拉格地区切哈地区的土壤进行了研究。本研究利用四种不同的土地利用类型(耕地、林地、桉树和野生森林)来评估和分析它们对土壤肥力的响应。选取2个不同的土壤深度(0-20 cm和20-40 cm),共采集48个土壤样品(24个未扰动和24个扰动),3个重复进行实验室分析。结果表明,土壤的大部分理化性质均受到LUTs、SD及其相互作用的显著影响。结果表明:沙粒(43%)、粉砂(46.5%)和粘土(30.30%)在林地、灌溉区和耕地中含量最高;土壤SD以粉砂质(40.9%)和粘土(28.3%)为主。除CUL外,所有lut的纹理类均为纹理类。CUL地下土壤容重最高(1.37 g cm-3), FL和ENFL表层土壤容重最低(1.06 g cm-3)。与容重相比,全孔隙度在FL和ENFL表层土壤中最高(60.1%),在CUL下层土壤中最低(48.3%)。两个因子共同影响土壤ph值,ENFL表层土壤ph值最高(6.54),EUCL底土ph值最低(4.82)。相比之下,高级区表层土壤有机质含量最高(7.48%),EUCL下层土壤有机质含量最低(3.55%)。全氮含量最高(0.37%)、最低(0.17%)的土壤分别为表层土壤和下层土壤。在ENFL表层土壤中Av.P值最高(22.69 mg kg-1), EUCL次表层土壤中最低(5.02 mg kg-1)。土壤CEC值最高为37.96 cmol(+) kg-1,最低为11.90 cmol(+) kg-1。EUCL土壤的交换性酸度最高值为1.85 cmol(+) kg-1。本研究表明,不同的lut和SDs对土壤肥力状况有显著影响。FL和enfl的土壤相对较肥沃。耕地上桉树盖度的增加和集约化耕作严重影响了土壤肥力,可能导致土壤酸度增加。适当的土地利用和各种土壤肥力管理措施对于解决土壤肥力丧失和酸度问题至关重要

Vedic mathematics strongly influences high school students’ capacity to extend mathematical units. The study compares Vedic arithmetic formulae to current mathematical science. The study’s technique is based on a retrospective-to-prospective design using past-to-present Vedic mathematics. The study collects data from both primary and secondary sources. Primary data were collected from 220 high school students using a planned schedule in pre- and post-Vedic mathematical phenomena.

This study aimed to examine the trend of cooperative unions towards quality coffee production and supply and identify the challenges of coffee farmers’ cooperative unions in Gimbo woreda (district). Ten cooperative unions located in the woreda were selected to conduct the study. To achieve the objective of the study descriptive research design was employed and to obtain relevant information, 333 union members were selected using a simple random sampling technique. Both primary and secondary data were collected through questionnaires, interviews and document analysis. Collected data were analyzed both qualitatively and quantitatively. The study revealed that farmers are effectively applying agronomic, physiological, pre- and post-harvest activities and producing quality coffee. However, they are not getting economic benefits from their product. Due to this, they are not motivated to produce high amounts and quality of coffee on their farmland. Cooperatives are not effectively providing services for their members. The government is also playing a role in improving the performance of cooperatives. Thus, it is recommended that all concerned bodies need to give due attention to improving the performance of cooperatives and members’ economic benefit
本研究旨在考察合作社联盟向优质咖啡生产和供应的趋势,并确定Gimbo woreda(区)咖啡农合作社联盟面临的挑战。本研究选取了全国10个合作工会进行研究。为了达到研究目的,采用描述性研究设计,采用简单随机抽样的方法,选取了333名工会成员,以获取相关信息。通过问卷调查、访谈和文献分析收集第一手和第二手资料。对收集到的数据进行定性和定量分析。研究表明,农民正在有效地应用农艺、生理、收获前和收获后活动,生产优质咖啡。然而,他们并没有从他们的产品中获得经济利益。正因为如此,他们没有动力在自己的农田里生产大量高质量的咖啡。合作社没有有效地为其成员提供服务。政府也在提高合作社绩效方面发挥作用。因此,建议所有有关机构都应适当注意改善合作社的业绩和成员的经济利益

When compared to conventional boost converters, it can be demonstrated that each submodule’s power can be controlled separately, improving the battery system’s available capacity. Faulty battery modules can be bypassed, increasing the system’s reliability and fault tolerance capability. The chosen approach is shown with cascaded system using proportional integral derivative (PID) controller and the Single-phase inverter with SPWM technique for the Stationary load applicationFindings: The proposed cascaded system act as a fault tolerant system since the source is the second-life battery even though there is fault has occurred in the system meets the load demand. These simulations are done in MATLAB and the results are discussed. The DC link voltage of the cascaded system has more ripple based on the tuning of the PID controller with the values of Kp,Ki, Kd the ripple can be decreased.Novelty: Cascaded system with a fault-tolerant system using the second life battery will promote the zero-carbon waste of the batter and it is the new approach
目的:控制功率流,从而提高可用电池的利用率,延长使用寿命,提高可靠性。减少总能源需求和全球变暖潜力,促进零废物。方法:提出了一种基于级联DC-DC变换器的二次电池可重构系统。与传统升压变换器相比,可以证明每个子模块的功率可以单独控制,从而提高电池系统的可用容量。故障电池模块可旁路,提高系统可靠性和容错能力。所选择的方法显示了级联系统使用比例积分导数(PID)控制器和单相逆变器与SPWM技术用于固定负载应用。研究结果:所提出的级联系统作为一个容错系统,因为源是二次寿命电池,即使系统中发生故障也能满足负载需求。在MATLAB中进行了仿真,并对仿真结果进行了讨论。通过调整PID控制器的Kp、Ki、Kd值,可以减小级联系统直流链路电压的纹波。新颖之处:采用二次寿命电池的级联容错系统将促进电池零碳浪费,是一种新方法

Beginning with a global inquiry for increasing technology-enabled learning and education, this article analyses Indian education policy responses in G20 nations. Educators and students in India are generally well-prepared to use best practices in tech-related education. Therefore, the G20 partnership must think about how to best encourage the development of educational systems and practices that are robust, efficient, equitable, and adaptive in order to better respond to and lessen the effects of current and future crises (United Nations 2020a; Reimers and Schleicher 2020). In this context, it is currently necessary to make provisions to improve access to the technology infrastructures for remote education within and outside the G20 countries. Additionally, to facilitate safer and more fluid transitions to remote modes of EduTech during school education in India is disrupted, educators, students, and parents require help and direction. Finally, the G20 must immediately look into more sustainable growth models in case the education sector experiences long-term difficulties.
本文从全球对增加技术支持的学习和教育的调查开始,分析了印度在G20国家的教育政策反应。印度的教育工作者和学生一般都做好了充分的准备,可以在与技术相关的教育中采用最佳实践。因此,G20伙伴关系必须考虑如何最好地鼓励发展稳健、高效、公平和适应性强的教育体系和实践,以便更好地应对和减轻当前和未来危机的影响(联合国2020a;Reimers and Schleicher 2020)。在此背景下,目前有必要制定相关规定,以改善G20国家内外远程教育的技术基础设施。此外,为了在印度学校教育中断期间更安全、更流畅地过渡到远程教育技术模式,教育工作者、学生和家长需要帮助和指导。最后,20国集团必须立即研究更可持续的增长模式,以防教育部门遇到长期困难。
