The lockdown, implemented in response to the COVID-19 epidemic, restricted the operation of various sectors in the country and its highlights a good environmental outcome. Thus, a comparison of air pollutants in India before and after the imposed lockdown indicated an overall improvement air quality across major Indian cities. This was established by utilizing the Central Pollution Control Board’s database of air quality monitoring station statistics, such as air quality patterns. During the COVID-19 epidemic, India’s pre-to-post nationwide lockdown was examined. The air quality data was collected from 30-12-2019 to 28-04-2020 and synthesized using 231 Automatic air quality monitoring stations in a major Indian metropolis. Specifically, air pollutant concentrations, temperature, and relative humidity variation during COVID-19 pandemic pre-to-post lockdown variation in India were monitored. As an outcome, several cities around the country have reported improved air quality. Generally, the air quality, on a categorical scale was found to be ‘Good’. However, a few cities from the North-eastern part of India were categorized as ‘Moderate/Satisfactory’. Overall, the particulate matters reduction was in around 60% and other gaseous pollutants was in 40% reduction was observed during the lockdown period. The results of this study include an analysis of air quality data derived from continuous air quality monitoring stations from the pre-lockdown to post-lockdown period. Air quality in India improved following the national lockdown, the interpretation of trends for PM 2.5, PM 10, SO2, NO2, and the Air Quality Index has been provided in studies for major cities across India, including Delhi, Gurugram, Noida, Mumbai, Kolkata, Bengaluru, Patna, and others.
为应对新冠肺炎疫情而实施的封锁限制了该国各部门的运营,并突出了良好的环境成果。因此,对印度实施封锁前后的空气污染物进行比较表明,印度主要城市的空气质量总体上有所改善。这是利用中央污染控制委员会的空气质量监测站统计数据库建立的,如空气质量模式。在新冠肺炎疫情期间,印度的全国封锁措施受到审查。空气质量数据收集于2019年12月30日至2020年4月28日,并使用印度一个主要大都市的231个空气质量自动监测站进行合成。具体而言,监测了新冠肺炎疫情期间印度封锁前后的空气污染物浓度、温度和相对湿度变化。结果,全国多个城市报告空气质量有所改善。一般来说,空气质量分类为“良好”。然而,印度东北部的一些城市被归类为“中等/满意”。总体而言,在封锁期间,颗粒物减少了约60%,其他气体污染物减少了40%。这项研究的结果包括对从封锁前到封锁后连续空气质量监测站获得的空气质量数据的分析。印度的空气质量在全国封锁后有所改善,在对印度主要城市的研究中,包括德里、古鲁格拉姆、诺伊达、孟买、加尔各答、班加罗尔、巴特那和其他城市,提供了PM 2.5、PM 10、SO2、NO2和空气质量指数的趋势解释。

Since snow load is one of the loads of designing the industrial shed roof, this research presents a new system to reduce the industrial sheds roof design. In this system, sensitive units of moisture and temperature, which can be adjusted with different areas, are installed on the shed’s roof. The mechanism of system is that the sensors in the units detect the presence of snow on the shed roof and send an order to connect electricity to the elements; therefore, the snow on the roof melts by the heat generated. In this system, solar panels are used to supply electricity. As with the help of this mechanism, snow does not remain on the roof, it is possible to eliminate the snow load in the calculations of the shed and apply at least the live load of the sixth regulation (Due to having a one-story shed, minimum live load applied and it used only for the foundation design of the structure.), this issue will create an economic plan in shed designing. According to the study conducted in this research, it is shown that the dimensions of the sheet beam used in the shed are reduced, which will significantly reduce the cost of construction and installation to some extent. In the following, two samples of sheds with a span of 20 meters in the presence of snow and the absence of snow in the software were modelled, and the results were compared with each other.
由于雪荷载是工业棚顶设计的荷载之一,本研究提出了一种新的减少工业棚顶设计的系统。在这个系统中,湿度和温度的敏感单元可以根据不同的区域进行调整,安装在棚顶上。系统的机制是,单元中的传感器检测到棚顶上是否有雪,并发出命令将电连接到各个元件;因此,屋顶上的雪被产生的热量融化。在这个系统中,太阳能板被用来供电。在这种机制的帮助下,雪不会留在屋顶上,因此有可能在棚的计算中消除雪荷载,并至少应用第6条规定的活载(由于有一个单层的棚,最小的活载应用,它只用于结构的基础设计),这个问题将为棚设计创造一个经济的计划。根据本研究进行的研究表明,减少了棚内使用的薄板梁的尺寸,这将在一定程度上显著降低施工和安装成本。下面分别对软件中有雪和无雪两种情况下,跨度为20米的两个棚子样本进行建模,并对结果进行比较。

Cadmium is one of the transition metals, known by the scientific name Cd. One of its main characteristics is the high toxicity, even in very little amounts. Cadmium is often released through industrial effluents, pesticides, chemical fertilizers, and the burning of fossil fuels. Since the presence of cadmium ions in the living organisms’ body, especially humans, can cause serious damage to the liver and pancreas, and also because its role in causing cancer has been proven, measuring very low amounts of this metal is of high importance. In the first step, this study has reviewed and analyzed common laboratory methods for measuring small amounts of cadmium. Then, according to economic, environmental, feasibility, speed, and accuracy factors, all available methods were evaluated using the ELECTRE technique. The results showed that the extraction methods using Dowex Optipore V-493 resin and extraction system in Triton X-114 surfactant, placed in the first and second positions.
镉是一种过渡金属,学名为Cd。它的主要特点之一是毒性高,即使是非常少量。镉通常通过工业废水、杀虫剂、化肥和燃烧化石燃料释放出来。由于镉离子存在于生物体体内,尤其是人体内,会对肝脏和胰腺造成严重损害,而且它在致癌中的作用已被证实,因此测量极少量的这种金属是非常重要的。在第一步,本研究回顾和分析了用于测量少量镉的常用实验室方法。然后,根据经济、环境、可行性、速度和准确性等因素,利用ELECTRE技术对所有可用的方法进行评估。结果表明,采用Dowex Optipore V-493树脂的提取方法和采用Triton X-114表面活性剂的提取体系,分别排在第一和第二的位置。

Cadmium is naturally present in the mineral cadmium sulfide which is a rare form of this element and the highest amount of cadmium is obtained from the extraction process of other minerals such as lead, copper and zinc. The release of this metal into the environment leads to widespread epidemiological effects. Therefore, measuring small amounts of this metal is also of particular importance. Small amount measuring methods of this metal are such as,preconcentration using solid phase extraction system using adsorbents. The main part of the preconcentration process is achieved by adsorption processes. In this study, the behavior of Freundlich and Langmuir adsorption isotherms for the capacity of TMON and IMNM adsorbents in cadmium adsorption has been evaluated by Power and Rational statistical distributions. At the end of the study, the constant coefficients of the Freundlich and Langmuir models were compared in both linear and non-linear modes. The results showed; the linearization method for the Kf coefficient of the Freundlich isotherm can cause errors equal to 41.6% in TMON adsorbent and 39.3% in IMNM adsorbent. Also, in parameter b, errors of 66.66% are obtained in TMON adsorbent and 32.45% in IMNM adsorbent.
镉天然存在于矿物硫化镉中,硫化镉是这种元素的一种罕见形式,最高含量的镉是从铅、铜和锌等其他矿物的提取过程中获得的。这种金属释放到环境中会导致广泛的流行病影响。因此,测量少量的这种金属也特别重要。这种金属的少量测量方法有,使用吸附剂的固相萃取系统进行预富集。预浓缩过程的主要部分是通过吸附过程实现的。在本研究中,TMON和IMNM吸附剂在镉吸附中的Freundlich和Langmuir吸附等温线的行为通过幂和有理统计分布进行了评估。在研究的最后,比较了Freundlich和Langmuir模型在线性和非线性模式下的常系数。结果表明:;Freundlich等温线Kf系数的线性化方法在TMON吸附剂中可导致41.6%的误差,在IMNM吸附剂中则可导致39.3%的误差。此外,在参数b中,TMON吸附剂的误差为66.66%,IMNM吸附剂的错误为32.45%。

Industrial control systems: The biggest cyber threat 工业控制系统:最大的网络威胁
Pub Date : 2020-11-06 DOI: 10.29328/JOURNAL.ACEE.1001026
Christos P. Beretas
Industrial control systems (ICS) are critical, as in these systems, cyber threats have the potential to affect, disorganize, change their mode of operation, act as an information extraction vehicle, and ultimately turn against itself. Creating risks to the system itself, infrastructure, downtime, leakage of sensitive data, and even loss of human life. Industrial control systems (ICS) are vital to the operation of all the modern automated infrastructure in the western world, such as power plant and power stations. Industrial control systems (ICS) differ from the traditional information systems and infrastructures of organizations and companies, a standard cyber security strategy cannot be implemented but part of it adapting to the real facts and needs of each country, legislation and infrastructure. These systems require continuous operation, reliability and rapid recovery when attacked electronically with automated control, isolation and attack management processes. Incorrect settings and lack of strategic planning can lead to unprotected operation of critical installations, as they do not meet the cyber security requirements. Industrial control systems (ICS) require special protection in their networks, as they should be considered vulnerable in all their areas, they need protection from cyber attacks against ICS, SCADA servers, workstations, PLC automations, etc. Security policies to be implemented should provide protection against cyber threats, and systems recovery without affecting the operation and reliability of operating processes. Security policies such as security assessment, smart reporting, vulnerability and threat simulation, integrity control analysis, apply security policy to shared systems, intrusion detection and prevention, and finally firewall with integrated antivirus and sandbox services should be considered essential entities.
工业控制系统(ICS)是至关重要的,因为在这些系统中,网络威胁有可能影响、破坏、改变其操作模式,充当信息提取工具,并最终反目成仇。给系统本身、基础设施、停机时间、敏感数据泄露甚至人员生命损失带来风险。工业控制系统(ICS)对西方世界所有现代自动化基础设施的运行至关重要,如发电厂和发电站。工业控制系统(ICS)不同于组织和公司的传统信息系统和基础设施,标准的网络安全战略无法实施,但它的一部分是适应每个国家、立法和基础设施的真实情况和需求。当受到电子攻击时,这些系统需要连续操作、可靠性和快速恢复,并具有自动控制、隔离和攻击管理流程。不正确的设置和缺乏战略规划可能导致关键设施的无保护操作,因为它们不符合网络安全要求。工业控制系统(ICS)需要在其网络中提供特殊保护,因为它们在所有领域都应被视为易受攻击,它们需要保护免受针对ICS、SCADA服务器、工作站、PLC自动化等的网络攻击。要实施的安全政策应提供针对网络威胁的保护,以及系统恢复,而不影响操作过程的操作和可靠性。安全策略,如安全评估、智能报告、漏洞和威胁模拟、完整性控制分析、将安全策略应用于共享系统、入侵检测和预防,以及最终具有集成防病毒和沙盒服务的防火墙,应被视为重要实体。

Crude oil exploration is a major economic venture in Nigeria which [1,2] noted has resulted to the release of polycyclic aromatic hydrocarbons and heavy metals into soils and water bodies through oil spillage. In soils, petroleum hydrocarbon creates conditions which lead to unavailability of essential nutrients to plants [3]. It implies that the soil remains unsuitable until the crude oil is degraded to a tolerable level. The amount of natural crude oil seepage was estimated to be 600,000 metric tons per year with a range of uncertainty of 200,000 metric tons per year [4,5]. The discharge of crude oil whether accidentally or due to human activities is a main cause of water and soil pollution and they constitute a serious environmental problem which can threaten human health and that of bene icial organisms in the environment [1].
原油勘探是尼日利亚的一项主要经济活动[1,2]指出,石油泄漏导致多环芳烃和重金属释放到土壤和水体中。在土壤中,石油碳氢化合物创造了导致植物无法获得基本营养的条件[3]。这意味着在原油降解到可容忍的水平之前,土壤仍然不合适。天然原油渗漏量估计为每年600000公吨,不确定性范围为每年200000公吨[4,5]。原油的排放,无论是意外还是由于人类活动,都是造成水土污染的主要原因,它们构成了一个严重的环境问题,可能威胁人类健康和环境中有益生物的健康[1]。

The discharge of crude oil whether accidentally or due to human activities is a main cause of water and soil pollution and they constitute a serious environmental problem which can threaten human health and that of bene icial organisms in the environment [1].","PeriodicalId":72214,"journal":{"name":"Annals of civil and environmental engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48021182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article discusses approaches to solving problems of accurately determining strength in kinematic pairs. It is known that the nature of the bonds imposed by kinematic pairs is determined by the geometric shapes of the elements of the pairs. For what, here, the bonds acted during the entire time the mechanism was moving, so that the elements of the kinematic pairs would continuously touch each other. Where it is recognized that one of the simplest methods for taking into account the inertia of a link is the principal moment method. How the contradiction is sought is here because the normal acceleration has a direction opposite because normal acceleration has a direction opposite to the link (directed toward the center), and the image of tangential acceleration is directed parallel to this acceleration. The following simplification can be made if the main vector of inertia is considered together with the weight of the link.
本文讨论了解决精确确定运动副强度问题的方法。众所周知,由运动对施加的键的性质由运动对的元件的几何形状决定。在这里,键在机构运动的整个过程中起作用,因此运动学对的元素将不断地相互接触。考虑连杆惯性的最简单方法之一是主力矩法。如何寻求矛盾是因为法向加速度具有相反的方向,因为法向加速具有与链接相反的方向(指向中心),并且切向加速度的图像平行于该加速度。如果将主惯性矢量与连杆的重量一起考虑,则可以进行以下简化。

Space medicine is a very vast subject ... indeed since it concerns all human medicine adapted to the very speci ic space environment. Space is a particularly aggressive environment for the human body adapted to live on Earth. For more than twenty years, following the creation of space stations, MIR irst and then the International Space Station (ISS) men (3 to 6) live and succeed each other permanently at about 300 400 km altitude to do scienti ic experiments. The purpose of this intervention was to explain what space medicine really is through its experience as an astronaut physician and to understand how this medicine can be useful and have spinoffs for Earthmen.
太空医学是一个非常广泛的学科。的确,因为它涉及到适应特殊空间环境的所有人类医学。对于适应地球生活的人体来说,太空是一个特别恶劣的环境。20多年来,随着空间站的建立,和平号和国际空间站(ISS)的人(3至6人)在大约300至400公里的高度永久地生活和接替彼此做科学实验。这次干预的目的是通过作为一名宇航员医生的经历来解释太空医学到底是什么,并了解这种药物如何对地球人有用并产生附带影响。
