Electrically conductive cementations composite has several advantageswhich include strain sensitivity and high conductivity (ECCC). The ECCC can also perform the role of a conductivity sensor in a safety system that monitors the health of a building. Understanding and predicting electrical resistivity as well as compressive stress are necessary when using ECCC (UCS). In this study, we developed ECCC using three conductivity fillers: waste steel slag (SS), graphite powder (GB), and near - field ground blast furnace slag (GGBS) (GGPS). By adjusting the concentrations of the three conductive fillers, cement, and curing age, we created 81 different mix ratio for the UCS test and 108 different concrete ratios for the conductivity test. Sandier soils are best for using ordinary Portland cement (OPC), which is frequently utilised for stabilising purposes. In a rotating kiln, unusual and local building materials like clay or other silicates are heated to high temperatures (>1500°C) to create Portland cement.

In a rotating kiln, unusual and local building materials like clay or other silicates are heated to high temperatures (>1500°C) to create Portland cement. Slag is a commercial waste product produced during the steelmaking process. At various phases of the steelmaking process, slag from both the electric arc furnace and the ladle furnace is produced in electric arc furnaces and refining ladle furnaces, respectively. A byproduct of blast furnaces used to manufacture iron, GGBS is a cementing ingredient mostly used in concrete. Between 1972 and 1976, the Battelle Memorial Institute in Geneva founded the Program in Science and Human Affairs to conduct research and address complex, interconnected concerns. DEMATEL is one of the decision-makers with a number of criteria. DEMATEL technique is frequently used to extract a difficult problem's complex structure. DEMATEL's goal is to scale from a complex system and the link between causal factors in order to describe the system's perceptible organisational structure. The cause and effect link between the criteria is evident while evaluating complexity. According to the results, ordinary Portland cement (OPC) has the highest ranking, while graphite powder (GP) has the lowest ranking. Resulting in ordinary Portland cement (OPC) ranked first, graphite powder (GP) has low rank.
导电水泥基复合材料(ECCC)具有应变敏感性和高导电性等优点。导电水泥复合材料还可以在监测建筑物健康状况的安全系统中发挥传导性传感器的作用。在使用 ECCC(UCS)时,有必要了解和预测电阻率以及压应力。在这项研究中,我们使用三种导电填料开发了 ECCC:废钢渣 (SS)、石墨粉 (GB) 和近场磨细高炉矿渣 (GGBS) (GGPS)。通过调整三种导电填料、水泥和养护龄期的浓度,我们为 UCS 测试创造了 81 种不同的混合比,为导电性测试创造了 108 种不同的混凝土配合比。含沙量较高的土壤最适合使用普通硅酸盐水泥(OPC),这种水泥通常用于稳定土质。在回转窑中,粘土或其他硅酸盐等不常见的当地建筑材料被加热到高温(>1500°C),从而制成波特兰水泥。沙质土壤最适合使用普通硅酸盐水泥(OPC),这种水泥通常用于稳定土质。在回转窑中,粘土或其他硅酸盐等不常见的当地建筑材料被加热到高温(>1500°C),以生产波特兰水泥。炉渣是炼钢过程中产生的一种商业废品。在炼钢过程的不同阶段,电弧炉和钢包炉的炉渣分别产生于电弧炉和精炼钢包炉。GGBS 是炼铁高炉的副产品,是一种水泥成分,主要用于混凝土。1972 年至 1976 年间,日内瓦巴特尔纪念研究所(Battelle Memorial Institute)成立了科学与人类事务计划(Program in Science and Human Affairs),以开展研究并解决复杂、相互关联的问题。DEMATEL 是具有若干标准的决策者之一。DEMATEL 技术常用于提取难题的复杂结构。DEMATEL 的目标是从复杂的系统和因果因素之间的联系中进行扩展,以描述系统可感知的组织结构。在评估复杂性时,标准之间的因果联系是显而易见的。结果显示,普通硅酸盐水泥(OPC)的排名最高,而石墨粉(GP)的排名最低。结果是普通硅酸盐水泥(OPC)排名第一,石墨粉(GP)排名靠后。

The development of every country's economy depends on entrepreneurship. There are many different themes covered in the study of entrepreneurship nowadays. Numerous studies that examine the motivations for starting a business have been conducted; the bulk of them focus on personality traits and other psychological factors. However, actual entrepreneurial education, including internships and business incubators, receives less focus in the research. The current study intends to fill this gap by empirically investigating the impacts of internship programmed and company incubators on students' entrepreneurial aspirations at higher study levels at universities. After gathering information from students using a structured questionnaire, partial least square structural equation modelling technique is used with the help of Smart PLS software. The statistics show that business incubators and internship programmed have a strong and statistically significant impact on entrepreneurial tendencies In order to improve entrepreneurship's ability for risk-taking, inventiveness, and initiative as well as how these attributes might address the lack of entrepreneurial consciousness among business students, the current study can help policy-makers get a better knowledge of entrepreneurship.
每个国家的经济发展都有赖于创业精神。如今,创业研究涉及许多不同的主题。对创业动机的研究不胜枚举,其中大部分侧重于个性特征和其他心理因素。然而,包括实习和企业孵化器在内的实际创业教育却较少受到研究关注。本研究旨在通过实证调查实习计划和企业孵化器对大学高年级学生创业愿望的影响来填补这一空白。在使用结构化问卷收集学生信息后,本研究借助 Smart PLS 软件使用了偏最小二乘法结构方程建模技术。统计结果表明,企业孵化器和实习计划对创业倾向有很强的影响,且在统计上有显著意义。为了提高创业者的风险承担能力、创造力和主动性,以及这些特质如何解决商科学生缺乏创业意识的问题,本研究可以帮助政策制定者更好地了解创业精神。
