The climate change is strongly affected by the increase of anthropogenic greenhouse gas emissions, such as carbon dioxide, methane, nitrous oxide, and fluorinated gases. Other important atmospheric factors of climate change are stratospheric sulfur aerosols, whose ability to reflect solar radiation back to the space cause cooling effect. Sulfur aerosols have common natural and anthropogenic origin. The volcanos are a major source of particles in the stratosphere, whose lifetime depends on various atmospheric processes � water condensation, rains and winds. Chapanov determines long-term influence of Total Solar Irradiance (TSI) on global volcanic sulfate with periodicity 93-230 years in [1]. A new monthly volcanic forcing dataset had been created by Ammann et al. [8,9]. This dataset presents the seasonal and latitudinal influence on global climate, where negative radiative forcing from volcanic activity is visible in the early 20th century and after 1960. The monthly volcanic data cover the period between 1890 and 1999. The volcanic aerosols are calculated in 64 zonal band with latitude step of 2.8 degrees. The variations of sulfur aerosols over European latitude belt (39.2 N � 56 N) are compared with mean temperature and cycles of solar Indices. Common temperature and sulfur cycles are investigated by means of the Method of Partial Fourier Approximation (PFA). These cycles have good agreement in 11 narrow frequency bands, whose periodicity are between 2.9 and 36.6 years. Possible use of the results in climate study and forecast is discussed.
气候变化受到二氧化碳、甲烷、一氧化二氮和氟化气体等人为温室气体排放增加的强烈影响。其他重要的气候变化大气因子是平流层的硫气溶胶,其将太阳辐射反射回空间的能力导致冷却效应。含硫气溶胶有共同的自然和人为来源。火山是平流层颗粒的主要来源,这些颗粒的寿命取决于各种大气过程——水凝结、降雨和风。Chapanov测定了太阳总辐照度(Total Solar Irradiance, TSI)对全球火山硫酸盐的长期影响,周期为93-230年[1]。Ammann等人创建了一个新的月度火山强迫数据集[8,9]。该数据集展示了火山活动对全球气候的季节性和纬度影响,其中火山活动的负辐射强迫在20世纪初和1960年以后是可见的。每月火山数据涵盖1890年至1999年期间。火山气溶胶在64个纬向带中计算,纬度步长为2.8°。将欧洲纬带(39.2 N ~ 56 N)硫气溶胶的变化与平均气温和太阳指数周期进行了比较。用偏傅立叶近似法(PFA)研究了温度循环和硫循环。这些周期在11个窄频带具有较好的一致性,周期在2.9 ~ 36.6年之间。讨论了这些结果在气候研究和预报中的应用。

Biotope or habitat preferences are important species characteristics that can be used for understanding their ecology, as well as their conservation, and even as a tool for crime investigations for detection of post-mortem body manipulation. However, the characterization of species� habitat preferences can be difficult. There are several limiting factors like lack of quantitative data and reliance on anecdotal evidence for this trait. Further, we must consider the reaction to the border between two neighboring habitats. These ecotones are important biodiversity hotspots in the landscape, which combine characteristics of both habitats, but some specialist species seem to avoid them. To characterize habitat preference of the potentially forensically important necrophagous beetle Oiceoptoma thoracicum (Linnaeus, 1758), we set up an experiment in the transition zone between the meadow and forest habitat. The individuals of O. thoracicum were collected using baited pitfall traps across two habitats and at ecotone. The traps were exposed for two weeks after which the samples were taken to the laboratory, where they were sorted and the specimens of O. thoracicum were sexed and counted. The obtained data were evaluated by a generalized linear model to establish the relationship between the presence and abundance of the focal species and distance from the ecotone. We found that the abundance of the species significantly changes along the forest-meadow gradient and shows a preference for woods. Its abundances at the ecotone and on meadows was low, showing a clear preference for forest habitats. This has important implications for the forensic use of the species, as it can be used to detect post-mortem body manipulation.
生物群落或栖息地偏好是重要的物种特征,可用于了解其生态及其保护,甚至可作为犯罪调查的工具,用于检测死后尸体操纵。然而,物种栖息地偏好的表征可能是困难的。有几个限制因素,如缺乏定量数据和依赖轶事证据的这一特点。此外,我们必须考虑对两个相邻栖息地之间边界的反应。这些过渡带是景观中重要的生物多样性热点,它结合了两种栖息地的特征,但一些特殊物种似乎避开了它们。为了研究具有重要法医学意义的尸食性甲虫Oiceoptoma thoracic (Linnaeus, 1758)的生境偏好,我们在草甸和森林生境的过渡地带进行了实验。采用诱捕法在2个生境和交错带采集胸胸胸腹圆蚧个体。捕集器暴露两周后,将标本送到实验室进行分类,并对胸腹棘球蚴标本进行性别鉴定和计数。利用广义线性模型对得到的数据进行评价,以建立焦点物种的存在度和丰度与与交错带的距离之间的关系。研究发现,该物种的丰度沿森林-草甸梯度变化显著,并表现出对森林的偏好。其在交错带和草甸的丰度较低,表现出对森林生境的明显偏好。这对该物种的法医应用具有重要意义,因为它可以用来检测死后的尸体操纵。

During the process of drilling wells, it is necessary to have information about the composition of the soil layers through which the drill passes. This will optimize the parameters of rotation of the drill, the load on the drill, as a result of which equipment wear will be reduced. It will also make it possible to lay optimal trajectories during well drilling and track the penetration of the drill into the target layer. This issue is especially relevant for the oil industry, where production is carried out at great depths with a complex structure of soil and rocks. Obtaining this information becomes possible due to the control of the phase changes of the probing electrical signal on the receiving lines of the electrodes of the geoelectric monitoring system. This article discusses the use of the phase-metric method in relation to the problems of controlling the process of drilling wells, and gives an overview of the technical aspects of vertical electrotomography by the phase-metric method. A description of a laboratory experiment on the study of the effectiveness of the control of the drilling process by the phase-metric method is given. A study of the dynamics of changes in the phase signals of the receiving lines of electrodes in the process of passing through soil layers with different characteristics is shown, which affects the change in the parameters of the probing electrical signal. The research results are accompanied by graphic material confirming the metrological possibilities of the proposed phase-metric method. This will optimize drilling parameters in real time.
在钻井过程中,有必要获得有关钻头所经过的土层组成的信息。这将优化钻头的旋转参数,钻头上的负载,因此设备的磨损将减少。它还可以在钻井过程中铺设最佳轨迹,并跟踪钻头进入目标层的情况。这个问题与石油工业尤其相关,因为石油生产是在土壤和岩石结构复杂的深层进行的。通过控制地电监测系统电极接收线上探测电信号的相位变化,可以获得这些信息。本文讨论了相位法在控制钻井过程中的应用问题,并概述了用相位法进行垂直电层析成像的技术方面。本文介绍了用相位法对钻孔过程进行控制的有效性研究的室内实验。研究了电极接收线在穿越不同特征土层过程中相位信号变化的动力学规律,它对探测电信号参数变化的影响。研究结果附有图形材料,证实了所提出的相位计量方法的计量可能性。这将实时优化钻井参数。

Psychosocial risks are defined by the International Labor Organization in terms of interactions between job content, work organization and management, and other environmental and organizational conditions, on one hand, and employee conditions, skills, and needs, on the other. Thus, psychosocial risks refer to those interactions that prove to have a dangerous influence on employees' health through their perceptions and experience. Long-term involvement in stressful work situations can lead to onset of burnout syndrome, respectively a state of physical, emotional, and mental exhaustion. Health experts estimate that there are millions of people worldwide who suffer from burnout, which is considered a phenomenon of modern society. It is estimated that burnout is found in more than half of the world's active population. More and more organizations either create or buy, programs designed to support employees in preventing the onset of general and occupational stress or, if it has already settled, to assist them in managing it in the most adaptive way possible. The golden rule that prevention is better than cure also applies to psychosocial risk management approaches. The paper addresses the issue of organizational stressors from a theoretical point of view, underlining the most common types of stressors that have the potential to interfere with the work of intervention and rescue personnel.
国际劳工组织根据工作内容、工作组织和管理以及其他环境和组织条件与员工条件、技能和需求之间的相互作用来定义社会心理风险。因此,社会心理风险是指那些通过员工的感知和经验证明对其健康产生危险影响的相互作用。长期处于压力大的工作环境中会导致倦怠综合症的发作,分别是一种身体、情感和精神疲惫的状态。健康专家估计,全世界有数百万人患有职业倦怠,这被认为是现代社会的一种现象。据估计,世界上一半以上的活跃人群都存在过劳现象。越来越多的组织创建或购买旨在帮助员工预防一般压力和职业压力发作的计划,或者,如果已经解决了,帮助他们以最适应的方式管理它。预防胜于治疗的黄金法则也适用于社会心理风险管理方法。本文从理论角度阐述了组织压力源的问题,强调了最常见的压力源类型,这些压力源有可能干扰干预和救援人员的工作。

Studies aimed at improving the efficiency of the field preparation of hydrogen sulfide and mercaptan-containing oil are especially relevant in connection with the tightening of regulatory requirements for quality and safety indicators of commercial oil. The Technical Regulation (TR) of the Eurasian Economic Union TR 045/2017 �On the safety of oil prepared for transportation and (or) use� establishes uniform requirements for the safety indicators of oil delivered through trunk pipelines, as well as used as a raw material in oil refineries or petrochemical plants: hydrogen sulfide content - no more than 20 ppm, the total content of methyl and ethyl mercaptans - no more than 40 ppm. The proposed technology for cleaning oil stripping gas from hydrogen sulfide and mercaptans meets the requirements of modern oil safety standards and can be implemented in the format of a modular-block plant. It is possible to adapt the plant to operating conditions, modify and complete the plant, taking into account the content of light hydrocarbons and hydrogen sulfide in the oil being purified and mercaptans. The selected technological version of the installation scheme is the most rational for the construction of the installation according to the block-modular principle (for installation of the installation on site from blocks of various functional purposes).

Ductile iron is currently one of the most popular construction materials. Its mechanical properties are close to those of steel. The basic material in the production of ductile iron is gray iron, which can be produced in a cupola or in an electric induction or electric arc furnace. After tapping the gray cast iron from the furnace, the gray cast iron is processing into ductile iron. This process is called modification. Magnesium and its alloys and cerium are most often used as modifiers. In addition to the modification, the cast iron must then be inoculated. This paper deals with the impact of gray cast iron modification on the working environment. The experiments were performed in two foundries, where three modification technologies were used: the pouring method, the Tundisch cover and the Flottret method. The aim of the experiments was to determine how the individual modification methods affect the development of magnesium vapor, the content of carbon monoxide in the working environment and the temperature in the working environment. During the experiments, the CO content and temperature were measured before the modification itself, immediately after the modification and one hour after the modification. The greatest development of CO occurred after the modification. This was most significant in the pouring method. A similar situation occurred in the case of a change in temperature. Within one hour of the start of the modification, both the CO content and the ambient temperature returned to the original level before the modification.
球墨铸铁是目前最流行的建筑材料之一。它的机械性能与钢相近。生产球墨铸铁的基本材料是灰铸铁,可以在冲天炉中生产,也可以在电感应炉或电弧炉中生产。灰口铸铁出炉后,被加工成球墨铸铁。这个过程称为修改。镁及其合金和铈是最常用的改性剂。除改性外,还必须对铸铁进行孕育处理。本文论述了灰口铸铁的变质处理对工作环境的影响。在两家铸造厂进行了试验,其中使用了三种改性技术:浇注法、Tundisch盖法和Flottret法。实验的目的是确定单个改性方法如何影响镁蒸气的发展,工作环境中一氧化碳的含量和工作环境的温度。在实验中,分别测定了改性前、改性后和改性后1小时的CO含量和温度。CO的最大发展发生在改性后。这在浇筑方法中最为显著。在温度变化的情况下也发生了类似的情况。改造开始后1小时内,CO含量和环境温度均恢复到改造前的水平。

The design of a suitable ventilation method for buildings aims primarily to improve the quality of the indoor environment of buildings and thus to influence individual parameters of the indoor environment such asCO2concentration, air purity, the required amount of fresh air according to the proposed operation of the building, temperature and humidity. Proper design and installation of a forced ventilation system with heat recovery can significantly reduce the energy required for heating or cooling. The paper focuses on the ventilation of a building in summer and its effect on the indoor air temperature, which is an important parameter in the assessment of thermal stability. The building under consideration is a building designed using lightweight building structures that meet the standard requirements for the thermal technical properties of a building in the passive standard. The computer program DesignBuilder will be used for the calculation, which allows the assessment of alternative ventilation solutions under identical climatic conditions by means of dynamic simulation on a 3D model of the building.

Harvested bee pollen has been used since ancient times for its healthy properties and nutritional value. In terms of composition, bee pollen contains a large number of different substances such as proteins, carbohydrates and lipids as well as phenolic organic compounds. The protein content is the second most abundant component, its levels (10 to 40%, w/w) depending on the type of plant. Recently, numerous studies have demonstrated the beneficial properties of pollen in promoting health and reducing the risk of developing certain illnesses. In addition, the anti-oxidative and anti-aging effects have provided beneficial support for the development of bee pollen in the field of cosmetics. In this study, the effect of sonication treatment on the protein content of linden and hawthorn pollen was evaluated. Quantitative information regarding the protein content of sonicated extracts was determined by Bradford method while the antioxidant capacity of protein extract was evaluated using the DPPH free radical method. Furthermore, one dimensional electrophoresis and mass spectrometric analysis was used to acquire a more detailed description of pollen protein content.

During development, flows are formed within the route and gradient conditions by trough-forming processes. Sensitive changes of the landscape and interventions in the water flows caused mainly in the last century in Czechia and the pressure of agricultural management are the cause of major changes in flows and more frequent occurrences of hydrological extremes. These phenomena cause problems in the form of migration permeability, higher pollution concentrations or higher water temperatures. The aim of the paper was (I) to design a boulder chute with a stilling basin and an intake facility, (II) to model the design in a 3D model into an existing terrain model and (III) to verify the suitability of the design using a hydraulic model in a complex solution of small water reservoir restoration. The digital terrain model was modeled on the basis of a detailed focus in the Atlas software. The designed boulder chute with the still basin and the intake facility was manually added to the terrain model to the existing side pond. The hydraulic modeling in the stream was realized by a 1D model in the HEC � RAS program, both for the existing and for the design state. The case study was applied to the Skalicka small water reservoir in the Czech Republic. The result is whether the design has improved the hydraulic conditions of the unsatisfactory condition of the stream, and further the results form the basis for a comprehensive reconstruction of the existing small water reservoir.
在发展过程中,水流是在路线和梯度条件下通过槽形过程形成的。在捷克,景观的敏感变化和对水流的干预主要是在上个世纪造成的,农业管理的压力是水流发生重大变化和更频繁发生水文极端事件的原因。这些现象以运移渗透率、更高的污染浓度或更高的水温的形式造成问题。本文的目的是(I)设计一个带有消力池和取水设施的圆石溜槽,(II)将3D模型中的设计建模到现有的地形模型中,(III)使用水力模型验证设计在小型水库修复复杂解决方案中的适用性。数字地形模型是在Atlas软件中详细焦点的基础上建模的。将设计的带有静水池和取水设施的圆石溜槽手动添加到现有侧池的地形模型中。在HEC - RAS程序中,通过一维模型实现了水流的水力建模,包括现有状态和设计状态。该案例研究应用于捷克共和国的Skalicka小水库。其结果是设计是否改善了水工条件不理想的河道,进而形成对现有小水水库进行综合改造的依据。
