A comprehensive understanding of plant associations, especially in transition areas can be achieved by identification of vegetation and study of relationships between plant species and environment. Borders of ecotones and forest communities (Tiremrud basin in the southern part of Tonekabon, Iran) were found based on environmental factors such as elevation, slope and changes in floristic patterns. Totally, 44 plots (20 × 20 m) were collected by the transect method with at least one sample plot per contour line and 50 m interval. A total number of tree species was recorded separately in each sample plot. Herbaceous species were sampled based on the Brown-Blanket cover percentage and frequency of vegetative elements by 5 × 2 m2 micro plots in four corners and centre of each main plot. Four ecological groups were identified on altitudes 2070, 1236, 924, and 375 m above sea level with mean slopes of 43, 50, 40, and 59%, respectively. The first and fourth ecological groups were at the highest and the lowest elevations, respectively, while the second and third ones in the middle of the two groups. A comparison of ecological groups in terms of plant biodiversity indicated significant differences altogether. In terms of species diversity indices, Shannon-Wiener and Simpson-Pilo ​​revealed that the first, fourth, and second ecological groups had maximum, minimum, and average values, respectively. According to findings of this study, ecological groups had significant differences in terms of altitude factor.
通过植被鉴定和植物物种与环境关系的研究,可以全面了解植物关系,特别是在过渡区。在海拔、坡度和植物区系格局变化等环境因子的基础上,发现了过渡带和森林群落的边界(伊朗Tonekabon南部Tiremrud盆地)。样条法共采集样地44个(20 × 20 m),每条等高线至少1个样地,间隔50 m。每个样地分别记录树种总数。在每个主样地的四角和中心设置5 × 2 m2的小样地,根据褐毯覆盖百分比和营养元素频率对草本植物进行取样。在海拔2070、1236、924和375 m,平均坡度分别为43、50、40和59%的4个生态类群。第一和第四生态群分别处于海拔最高和最低的位置,第二和第三生态群处于海拔中间的位置。在植物多样性方面,各生态类群的比较显示出显著的差异。在物种多样性指数方面,Shannon-Wiener和Simpson-Pilo分别显示第一、第四和第二生态类群具有最大值、最小值和平均值。研究结果表明,各生态类群在海拔因子上存在显著差异。

The aim of this study was to assess the abilities of European Court of Human Rights (ECtHR) to adjudicate upon cases concerning violations to environment upraised from nuclear accidents. This was non-causal research, based on qualitative methods. With respect to information gathering, the document and library research process were employed, then qualitative method was applied to analyse the information, by which international rules governing the issue and related case law of ECtHR was studied, assessed and analysed. Findings indicated that ECtHR has accepted the environment rights by broad interpretation of article 8 of the European Convention on Human Rights (ECHR). However, in the Court’s precedent, applications with no actual victim were not considered as violation in the convention. The latest approach taken by ECtHR, taking prevention principle into account, could improve its abilities to protect potential victims of violations caused by nuclear accidents due to environmental rights. In conclusion, despite some barriers against the complaint processes in the Court, new approach was recognised as a more protective one.
这项研究的目的是评估欧洲人权法院(欧洲人权法院)对核事故引起的环境破坏案件作出裁决的能力。这是一项基于定性方法的非因果研究。在信息收集方面,采用文献和图书馆研究的方法,然后采用定性的方法对信息进行分析,通过研究、评估和分析管理该问题的国际规则和相关的欧洲人权法庭判例法。调查结果表明,欧洲人权法院通过对《欧洲人权公约》第8条的广泛解释接受了环境权。但是,根据法院的先例,没有实际受害者的申请不被视为违反《公约》。欧洲人权法院考虑到预防原则所采取的最新办法,可以提高其保护因环境权利而受到核事故侵害的潜在受害者的能力。最后,尽管法院的申诉程序存在一些障碍,但人们认为新的办法是一种更具保护性的办法。

The main objective of this work is to study the psychological impact (stress and depression) of the mandatory quarantine applied on the Moroccan population in order to limit the spread of the new coronavirus (COVID-19), then the study of the psychometric properties of the Arab BDI-II in the general Moroccan population. 263 respondents were asked to respond to a BDI-II and PSS-10 socio-demographic questionnaire conducted during the first month of quarantine. 55.9% of the respondents were in a normal state of stress and 36.1% in a moderate state. However, 38.4% and 27.8% exhibited minimal and severe depression respectively. The results of factor analysis with the varimax rotation method revealed three factors predicting 55.56% of the total variance of BDI-II, while two factors predicting 60.97% of the total variance of PSS-10. Cronbach's alpha values for BDI and PSS-10 were α = 0.93 and α = 0.58 respectively. In conclusion, the BDI-II is a reliable and valid assessment for measuring symptoms of depression in the general Moroccan population and also very important to pay more attention to the side effects of mandatory quarantine.
这项工作的主要目的是研究为限制新型冠状病毒(COVID-19)的传播而实施的强制性隔离对摩洛哥人口的心理影响(压力和抑郁),然后研究阿拉伯BDI-II在摩洛哥一般人口中的心理测量特性。263名答复者被要求对隔离第一个月期间进行的BDI-II和PSS-10社会人口调查问卷作出答复。55.9%的被调查者处于正常压力状态,36.1%的被调查者处于中等压力状态。然而,38.4%和27.8%分别表现为轻度和重度抑郁。方差最大旋转法因子分析结果显示,3个因子预测BDI-II总方差的55.56%,2个因子预测PSS-10总方差的60.97%。BDI和PSS-10的Cronbach α值分别为α = 0.93和α = 0.58。总之,BDI-II是衡量摩洛哥一般人口抑郁症状的可靠和有效的评估,对于更加注意强制性隔离的副作用也非常重要。

360 pieces of Persian sturgeon fingerlings (1.94 ± 0.75 g) were exposed to various sublethal doses of disinfecting chemicals commonly used in aquaculture such as sodium chloride and methylthioninium chloride in order to investigate their impacts on bacterial loads of skin, gill and surrounding water and to define the histopathological status of gill and liver tissues. The sublethal concentrations were determined after a pre-test, then the experiment was performed  in four treatments with three replicates inside the glass aquariums with stocking density of 10 fish (1-3 g) per aquarium. The treatments included 5, 6.3, 8.06 and 10.23 mg L-1 sodium chloride and  also 1, 1.56, 2.45 and 3.83 mg L-1 methylthioninium chloride. A control group (with no chemical added) was set up for each experiment. After exposure to treatments during 96 h, the microbial and histopathological examinations were carried out. Hemorrhage, elongation of secondary lamellae, adhesion of secondary lamellae, hypertrophy of supporter cartilage, mucus coagulation and secretion, hyperplasia, lamellar necrosis and clubbing of gill lamellae were observed on the fish gills. Biliary depression, hemorrhage, cell necrosis and degeneration of lipid were also found in liver. The severity of these effects was  dose-dependent. Only the sublethal concentration of methylthioninium chloride significantly influenced bacterial load (CFU g-1) on skin, while other treatments of sodium chloride and methylthioninium chloride did not exhibit any significant effects. In conclusion, the sublethal doses of methylthioninium chloride and sodium chloride showed no obvious disinfecting effect on gill, skin and surrounding water of Persian sturgeon fingerling. Nevertheless, histopathological alterations were observed on fish gill, skin and also  liver of all treatments.
将360条波斯鲟鱼种(1.94±0.75 g)暴露于各种亚致死剂量的水产养殖常用消毒化学品,如氯化钠和甲基硫代氯化铵,以研究它们对皮肤、鳃和周围水细菌负荷的影响,并确定鳃和肝脏组织的组织病理学状态。预试后测定亚致死浓度,然后在玻璃水族箱内进行4个处理,3个重复,每个水族箱放养10尾鱼(1-3 g)。处理分别为5、6.3、8.06和10.23 mg L-1氯化钠和1、1.56、2.45和3.83 mg L-1甲基硫代氯化钠。每组设1个对照组,不添加任何化学物质。处理96 h后,进行微生物和组织病理学检查。在鱼鳃上观察到出血、次级片伸长、次级片粘连、支撑软骨肥大、粘液凝固分泌、片层增生、片层坏死和鳃片棒状。肝脏还可见胆道抑制、出血、细胞坏死和脂质变性。这些影响的严重程度是剂量依赖性的。只有亚致死浓度的甲基硫鎓氯显著影响皮肤上的细菌负荷(CFU g-1),而氯化钠和甲基硫鎓氯的其他处理没有表现出任何显著影响。综上所述,亚致死剂量甲基硫代氯化铵和氯化钠对波斯鲟鱼种鳃、皮肤及周围水体的消毒效果不明显。然而,在所有治疗组的鱼鳃、皮肤和肝脏均观察到组织病理学改变。

Urgent is growing to have reliable information from the country's water resources. In recent years, data mining models such as artificial neural network (ANN), gene expression programming, Bayesian network, machine algorithms, such as a support vector machine (SVM), and Random Forest have found widespread use in the field of simulation and prediction of components in aquatic ecosystems. Variables vary greatly on water quality parameters (due to nonlinear and complex relationships). Therefore, conventional methods are not eligible to solve water resource quality management problems. The aim of this study was to investigate the possibility of simulating the spatial and temporal alterations in water quality parameters during the period 1985-2014 in Anzali Wetland using a SVM model. Based on principal components analysis (PCA), the parameters EC, TDS, pH and BOD5 were selected for analysis in this study. Spearman correlation was calculated to determine the inputs of the model and the correlation coefficient(CC) between the water quality parameters. According to the results of the correlation table analysis, 8 types of structures including different inputs were used to predict the parameters with machine vector. In the next stage, 70% of the data were used to train, while the rest were used for analyzing the models. Criteria for determination coefficient (R2) and root mean square error (RMSE) were used for evaluation and model performance. The results revealed that in verification stage among different used models, the pH had the highest accuracy (0.95), while the lowest RMSE (0.20). Trend of alterations for optimal model of each parameter on a time scale, indicated an adequate estimation at most points. In general, the results exhibited the appropriate accuracy and acceptable performance of the SVM model in simulating water parameters.
从该国水资源中获得可靠信息的紧迫性日益增加。近年来,人工神经网络(ANN)、基因表达编程(gene expression programming)、贝叶斯网络(Bayesian network)、支持向量机(SVM)等机器算法、随机森林(Random Forest)等数据挖掘模型在水生生态系统成分模拟和预测领域得到了广泛的应用。水质参数的变量变化很大(由于非线性和复杂的关系)。因此,传统的方法已不适合解决水资源质量管理问题。本研究旨在探讨利用SVM模型模拟安扎里湿地1985-2014年水质参数时空变化的可能性。采用主成分分析(PCA)方法,选取EC、TDS、pH、BOD5等参数进行分析。计算Spearman相关来确定模型的输入和水质参数之间的相关系数(CC)。根据相关表分析结果,采用8种不同输入的结构,用机器向量对参数进行预测。在接下来的阶段,70%的数据用于训练,其余的用于分析模型。采用决定系数(R2)和均方根误差(RMSE)标准评价模型的性能。结果表明,在验证阶段,不同使用的模型中,pH的准确度最高(0.95),RMSE最低(0.20)。各参数的最优模型在一个时间尺度上的变化趋势表明,在大多数点上都有充分的估计。总体而言,SVM模型在模拟水参数方面具有适当的精度和可接受的性能。

Landfills represent possible sources of diverse contaminants that can cause human health and ecological problems. The purpose of this study is to assess the pollution caused by a leachate from Ziama Mensouriah municipal landfill (north-eastern Algeria) affecting sediments and surface water. The water quality has been evaluated using River Pollution Index (RPI). Sediment contamination assessment was carried out using the pollution indicators including: contamination factor (CF), pollution load index (PLI) and geo-accumulation index (Igeo). According to the results, the RPI of Amsal River indicates an unpolluted water at site 1 (S1) (RPI = 2.5), severely polluted water at landfill effluent discharge (S2) (RPI = 8.25) and moderately polluted once at site (S3) (RPI = 5.5). In sediments, the order of mean concentration (µg g-1) of metals was Pb (156.2) > Cd (1.76). Furthermore, spatial distribution of both metals in sediments showed a significantly higher concentration at S2 indicating that metal pollution is caused by leachate from the studied municipal landfill. The Igeo values reveal that Pb was significantly accumulated compared to Cd. The highest CF values (>6) of Pb and Cd determined at S2 promote a high Pb and Cd contamination in that specific station. The PLI results showed that all sites, except for S1, were moderately to extremely heavy contaminated.
垃圾填埋场可能是各种污染物的来源,可能导致人类健康和生态问题。本研究的目的是评估来自Ziama Mensouriah市政垃圾填埋场(阿尔及利亚东北部)的渗滤液对沉积物和地表水的污染。采用河流污染指数(RPI)对水质进行了评价。采用污染因子(CF)、污染负荷指数(PLI)和地积指数(Igeo)等污染指标对沉积物进行污染评价。结果表明,Amsal河的RPI值为1号站点未受污染(S1) (RPI = 2.5)、2号站点填埋出水严重污染(S2) (RPI = 8.25)和1号站点中度污染(S3) (RPI = 5.5)。沉积物中金属的平均浓度(µg g-1)顺序为Pb (156.2) > Cd(1.76)。此外,沉积物中两种金属的空间分布在S2处的浓度均显著升高,表明金属污染是由城市垃圾填埋场的渗滤液引起的。Igeo值显示,与Cd相比,Pb有明显的累积。在S2测得的Pb和Cd的最高CF值(bbb6)促进了该特定站点的高Pb和Cd污染。PLI结果显示,除S1站点外,其余站点均为中度至重度污染。

The PLI results showed that all sites, except for S1, were moderately to extremely heavy contaminated.","PeriodicalId":9640,"journal":{"name":"caspian journal of environmental sciences","volume":"19 1","pages":"115-125"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68212026","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 main objective of this study is to investigate the production of carbon dioxide and its effective factors on CO2 emission in Iran and other parts of the world. The results show that by increasing the population and to meet their needs, it is necessary to increase the production of fossil fuels, in the less-developed or developing countries. Also in developing countries by increase in the gross domestic product (GDP), expenditure in these countries arises. Since there is no suitable infrastructure for optimal use of resources properly. In Iran, the rate of CO2 emission arises by increased population and GDP. However, in developed countries, due to the high technology available to the society and government, the amount of CO2 emission is decreasing or under the control. In order to create suitable infrastructure for proper management of resources and expenditure, as well as to reduce CO2 emission, long-term planning is suggested to be drawn. Hence, transferring the technology to the country and domesticating it, will help in this trend. Furthermore, cooperation with successful countries in the field of reduction and control of CO2 emission and using experiences of successful countries facilitated this trend.
本研究的主要目的是调查伊朗和世界其他地区二氧化碳的产生及其对二氧化碳排放的有效因素。结果表明,通过增加人口和满足他们的需求,有必要增加化石燃料的生产,在欠发达国家或发展中国家。在发展中国家,由于国内生产总值的增加,这些国家的支出也随之增加。因为没有合适的基础设施来最佳地利用资源。在伊朗,二氧化碳排放量随着人口和GDP的增长而上升。然而,在发达国家,由于社会和政府可以使用的高科技,二氧化碳的排放量正在减少或得到控制。为了建立适当的基础设施,妥善管理资源和开支,并减少二氧化碳的排放,建议制定长期规划。因此,将技术转移到该国并将其驯化,将有助于这一趋势。此外,与成功国家在减少和控制二氧化碳排放领域的合作以及利用成功国家的经验促进了这一趋势。

The main objectives of the present study were to determine the species composition of Caspian shad, genus Alosa and to estimate the LWR, CF, and Kn of A. braschnikowi and A. caspia during different months in the southeastern coast of the Caspian Sea. Two fishing methods, small mesh size beach seine and gillnet were used from December 2013 through July 2014. A. braschnikowi and A. caspia, were distinguished in the southeastern part of the Caspian Sea (Goharbaran), consisting of 57.1% and 42.9% of the Alosa catch, respectively. The slopes (b values) of the length-weight regression were 3.241 and 2.844 which were significantly different from 3 (P<0.05), indicating positive and negative allometric growth, respectively. The average CF of A. braschnikowi and A. caspia were calculated as 0.72 ± 0.12 and 0.83 ± 0.13, respectively. The average CF for both species were significantly different among months (P<0.001). There was a significantly negative correlation between size classes and CF of A. caspia. The Kn was greater than 1 for A. braschnikowi and lower than 1 for A. caspia indicating good well-being of A. braschnikowi as opposed to A. caspia in the southeastern Caspian Sea.
本研究的主要目的是确定里海东南沿海阿洛萨属里海鲥鱼的种类组成,并估计不同月份的布拉奇尼科威和里海鲥鱼的LWR、CF和Kn。从2013年12月到2014年7月,使用了两种捕鱼方法,小网眼沙滩围网和刺网。在里海东南部(Goharbaran)以A. braschnikowi和A. caspia为主,分别占Alosa渔获量的57.1%和42.9%。长度-权重回归的斜率(b值)分别为3.241和2.844,与3差异显著(P<0.05),分别为正异速生长和负异速生长。柠条和柠条的平均CF分别为0.72±0.12和0.83±0.13。两个物种的平均CF在月份间差异有统计学意义(P<0.001)。肉苁茸的大小类别与CF呈显著负相关。在里海东南部,布拉斯奇尼科布的生存指数大于1,而在里海东南部,布拉斯奇尼科布的生存指数小于1,表明布拉斯奇尼科布的生存状况较好。

This paper presents an overview of the current municipal solid waste (MSW) management in Rasht City, Guilan Province, Iran, followed by evaluating the potential for waste-to-energy. The data of different MSW functional elements were collected from previous works, available reports, interviews and meetings with specialists in the field. About 800 tons MSWs are generated in Rasht per day, of those, over 75% are organic wastes followed by paper and cardboard comprising 5.9%. The daily theoretical energy contained in the city MSWs was estimated to be over 591.62 megawatt hour (MWh, over 215942.54 MWh per year). Almost 500 tons of daily MSWs are directly transferred to Saravan as the biggest landfill in north of Iran with an area of about 30 ha, while the remaining portion is treated in the Guilan composting plant. Landfill mining calculations showed that we could recycle about 3008947, 36793, 61443 and 18366  tons of plastics, textile, wood and  rubbers collected from Saravan landfill respectively. A simple assessment of waste-to-energy potentials from organic wastes using operational conversion coefficients revealed that by employing the combination of waste-to-energy and gas turbine technology, an estimated energy of 227.668 MWh can be produced from the Rasht daily food wastes. Although MSW management in Rasht  has been improved over the last decade owing to the establishment of waste recycling and composting organization, however it is still far from the standard situation due to lack of comprehensive waste management planning, financial resources and infrastructures
本文概述了伊朗吉兰省拉什特市目前的城市固体废物(MSW)管理情况,然后评估了废物转化为能源的潜力。不同的城市固体废物功能元素的数据收集自以前的工作,现有的报告,采访和会议的专家在该领域。拉什特每天产生约800吨生活垃圾,其中有机废物占75%以上,其次是纸和纸板,占5.9%。据估计,城市生活垃圾所含的每日理论能量超过591.62兆瓦时(兆瓦时,每年超过215942.54兆瓦时)。每天有近500吨的生活垃圾被直接转移到萨拉万,这是伊朗北部最大的垃圾填埋场,占地约30公顷,而其余部分则在圭兰堆肥厂进行处理。垃圾填埋场采矿计算表明,我们可以分别回收约3008947吨、36793吨、61443吨和18366吨从Saravan垃圾填埋场收集的塑料、纺织品、木材和橡胶。利用操作转换系数对有机废物废物转化为能源的潜力进行了简单评估,结果表明,通过将废物转化为能源和燃气轮机技术相结合,Rasht每天的食物废物可产生约227.668兆瓦时的能源。虽然在过去的十年里,由于废物回收和堆肥组织的建立,Rasht的MSW管理得到了改善,但由于缺乏全面的废物管理规划,财政资源和基础设施,它仍然与标准状况相距甚远
