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.

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.

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.

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.

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. A critical room where the highest daily temperatures are reached will be used for the evaluation.

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.

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.","PeriodicalId":331146,"journal":{"name":"SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124808151","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}

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.
