Occupational health and safety is one of the necessary things in the industrial world. The problems that arose in the industrial era were the need for workers and increased productivity to be able to produce quality products. Health conditions and the availability of employee safety protections can affect work productivity. So that the safety and work safety culture in the workplace can be realized and can increase the safety performance index, an approach is implemented in the form of methods that can be applied to all organizations in the enterprise, one of which is behavior-based safety methods. The analysis of the data obtained shows that the factors that cause work accidents due to behavior are taken from the validity test, namely the factors of perception, communication and environment, because these three factors are very easily ignored by employees and company management. Environmental factors and personal protective equipment have no effect on work accidents as management always provides periodic education to its employees and enforces strict rules on the use of personal protective equipment. The magnitude of the influence of the variables studied in Behavior-Based safety in an effort to improve safe behavior was 79.7% and the remaining 20.3% was influenced by other unexamined items. The value of 79.7% consists of perception, communication and environment.

Published: August 2021

Genangan air di musim hujan dan tumpukan sampah telah menjadi masalah bagi banyak kota. Masalah lain yang sering dialami adalah kekeringan di musim kemarau yang diakibatkan sedikitnya air hujan yang mengisi kembali rongga tanah. Semakin banyaknya lahan hijau yang berubah fungsi menjadi bangunan menyebabkan berkurangnya daerah resapan air. Dengan berkurangnya daerah resapan air, hujan yang turun tidak meresap kembali ke dalam tanah melainkan mengalir di permukaan.Hal lain yang harus menjadi perhatian adalah pengelolaan sampah domestik. Apabila tidak dikelola dengan baik, sampah domestik menimbulkan masalah bagi lingkungan dan kesehatan. Perumahan Mutiara Gading Timur merupakan salah satu tempat di kota Bekasi yang hanya memiliki sedikit daerah resapan air karena sebagian besar lahan telah dipergunakan sebagai rumah atau jalan.Pembuatan lubang resapan biopori dapat menjadi alternatif untuk mengurangi volume air permukaan, meningkatkan tingkat resapan air hujan ke dalam tanah, dan mereduksi sampah organik yang mudah terurai. Lubang resapan biopori dibuat vertikal ke dalam tanah, dengan diameter 10 – 25 cm dan kedalaman sekitar 100 cm. Di bagian atas lubang diisi dengan sampah organik yang kemudian akan terurai menjadi kompos.Adanya kompos di bagian atas lubang biopori akan meningkatkan aktivitas organisme dalam tanah yang membentuk rongga-rongga untuk meresapkan air ke dalam tanah.

Purpose: to study the system of agricultural insurance with state support in Russia to identify its advantages. Discussion. The share of agriculture in Russia's gross domestic product structure is 4 % on average. Not only food security of the country, but also an increase in the exported agricultural products volume is ensured. Unfortunately, the industry’s development prospects do not have stable dynamics due to both internal and external economic factors. The experience of the developed countries shows that government support is a key factor for sustainable agricultural development and increasing its competitiveness. This need is due to the specific risks of agriculture. So, in crop production, weather risks which are annually exposed to a number of the country agrarian-oriented regions in areas of risky farming are unpredictable. The new system of agricultural insurance with state support, consisting of two types of subsidies, guarantees compensation for agricultural producers from extreme weather situations without reference to the timing of the harvest, and also provides for a insurance certificate cost reduction. With a view to sustainable development of agriculture, the government provides for other state support programs aimed at adjusting budgetary policy, concessional lending, as well as the introduction of new “short” grants for farmers. Despite the measures taken, the volume of agricultural insurance is lower than potential due to the loss of the insured's confidence in the insurance business. Conclusions. The agricultural insurance market in Russia has a tendency to expand since 2019, and the driver of this dynamics is the changed conditions of state support for agricultural insurance.

Purpose: the technology of laying geocomposite bentonite mats with the creation of an anti-filtration lining of increased reliability on the main canal section made under difficult conditions (in the presence of karst and suffusion phenomena) is considered. Materials and methods. The theoretical basis of the research is the indicators of physical, mechanical and technical characteristics of bentonite mats of various manufacturing companies. The practical component is flow charts, diagrams and technology for the work performance in natural conditions on the main canal section. Results and discussion: to reduce the filtration coefficient of anti-filtration coatings it is advisable to use two- and three-layer materials, which were used in the reconstruction of the Donskoy main canal section instead of polymeric materials, according to the results of the feasibility study. The work on laying sodium bentonite mats was carried out in difficult conditions after stopping the water supply, when there was an intense slope sloughing, and the water level in the canal was set below the groundwater level in the canal zone. At the same time, the canal was periodically cleaned with a dredger to remove the swollen soil along the canal bottom, and on the slopes – excavation with a dragline excavator, followed by transportation and soil storage in the slurry dump maps. Further, the work was carried out on maps with pools, separated by dams, where map sections were drained by a mobile pumping station. Conclusions: the use of the developed technology for canal cleaning and laying roll materials based on bentonite made it possible to reconstruct successfully the most dangerous canal sections. The introduction of a structural and technical solution in the form of a combined screen design ensures almost complete water imperviousity of the bottom and slopes of the canal.

Purpose: development of technology for repairing canal linings concrete with bitumen-polymer mastic using one- and two-component latex emulsion to reduce water loss through defects in the concrete lining. Materials and methods: the technology of repairing the damaged canal lining concrete coating includes: preparation of the base for the protective coating; preparation of bitumen-polymer mastic for its application (manually) or spraying (mechanized) over the entire repaired area; preparation of equipment, mechanisms and necessary inventory; preparation for the use of material components (reagent (component A) and hardener (component B)) for mechanized application; the process of applying bitumen-polymer mastic to the repaired area. Results: according to the results of a scientific research, when repairing the internal junctions of the bottom and slopes of canal concrete linings, it is necessary to arrange fillets that have a triangle with sides 10–50 mm long in their cross-section. The use of fillets when joining concrete linings will avoid excessive consumption of repair material. The application of a one-component material is carried out manually using a spatula to repair minor damage and reduce losses through them, and the application of a two-component mastic will allow mechanized repair of the largest (areal) damage. Conclusions: the application of one- and two-component cold-curing bitumen-polymer mastic for repairing concrete lining of irrigation canals to various damages on their surface (cracks, shears, concrete scaling, destroyed seams, etc.) is considered. Technological operations for the repair and restoration of canal concrete linings (a technological map for the concrete surfaces repair with a mechanized polymer composite material has been developed), including five stages of work are presented.

Purpose: to develop scenarios for filling and rational exploitation of the Chograi reservoir under the conditions of water resources shortage of (to conduct water balance studies). Materials and methods. The analysis of the use and distribution of water resources of the Chograi reservoir was carried out on the basis of actual data obtained for the period 2016–2020. To conduct water balance studies, a simulation water management model has been developed. It is based on the water allocation regime established in 2020. Results and discussion. Three possible scenarios for water management situation development in the Chograi reservoir have been developed, from which the optimal one has been selected. As the initial conditions for modeling, the regimes of water supply through the Tersko-Kumsky and Kumo-Manychsky canals, as well as water intake into the Chernozemelsky irrigation and watering system (CHOS) through the Chernozemelsky main canal were used. It was found that the actual value of water intake from the Terek river exceeded the plan, but remained below the water intake limit. Thus, it is possible to increase the volume of water supply to the reservoir due to withdrawal up to the values of the permitted limit. The analysis shows that the largest volume of water resources is used for feeding water bodies and for estuary irrigation. The second largest volume taken from the Chograi reservoir is the water supply through the bottom spillway to the downstream of the hydroelectric complex in the Eastern Manych river with expenditures exceeding sanitary releases. It is possible to reduce the consumed water resources by optimizing water management at the CHOS and reducing discharges. Conclusions. An optimal scenario for filling and rational operation of the Chograi reservoir has been developed, the fulfillment of the conditions of which will ensure the filling of the reservoir to the level of 20.35 m BS. At the same time, the volume of filling will be 209.75 million m³. The development of the water management situation according to the scenario under consideration will provide water resources for the CHOS for the period 2021–2022.

Purpose: to study the basic laws of cutting some plant materials, the knowledge of which will justify the rational parameters of a small unit for mechanization of removing the root crop tops. Materials and methods. The study was carried out experimentally on a computerized dynamometric unit, according to a non-compositional plan of the second order, using two most common types of root crops in cultivation in small holdings: table carrots and radishes. The value of the specific resistance of cutting tops was taken as an optimization parameter. Results. The study has shown that such factors as the blade incidence angle to the cutting direction, the blade width and the blade speed at the beginning of cutting are crucial and significantly affect the energy consumption of the top removal process. The most significant parameter is the blade width, the degree of influence of which is 2.2–18.2 times greater than the degree of influence of the other two factors. On average, a decrease in the blade width from 0.5 to 0.1 mm leads to a 3–5-fold decrease in the specific cutting force of the top, which confirms the prospects of using ultra-thin replaceable blades instead of a durable wide-faceted blade in the design of the plant-top removing machines. It was also found that at a blade speed of about 0.2 m/s and its blunted blade (b ≈ 0.5 mm), the tops are not cut, but crumpled or (in some cases) deflected by the knife. Conclusions. In general, the study allows to recommend the following rational parameters and operating modes of a small unit for mechanizing the root crops tops removal: the blade incidence angle to the cutting direction is from 30 to 45°; the blade width is about 0.1 mm; cutting speed is about 0.33 m/s.

Purpose: to study the effect of nonlinear soil movement in a deep-laid pit when designing an above-ground reservoir for irrigation as part of a system for regulating the precipitation runoff in the mountain-piedmont zone, subject to the technical regulations on the structure safety and subsequent safe operation. Materials and methods: the construction of a deep-laid pit in difficult geological design conditions in the mountain-piedmont zone of a hydraulic structure, which is responsible in terms of safety, namely, a system for regulating the rainfall runoff for irrigating agricultural land, prompted us to a more detailed study of measures to prevent soil uplift. In the analysis two conditions were modeled, namely, the construction of a deep-laid pit for an above-ground reservoir in the mountain-piedmont zone for irrigation without measures to prevent soil uplift and with appropriate measures. Results and discussion: when analyzing the results of soil uplift calculation without taking additional measures, it is stated that the soil uplift has a negative impact on the reservoir and in this case the hydraulic structure safety is not ensured. As an alternative option, the use of pit sheathing with a Larsen sheet pile model VL606a is considered. As a result of numerical modeling using the MIDAS software product, which made it possible to take into account all the factors necessary for solving such problems, it was found that the indicators are included in the confidence zone and, as a result, this structure will meet all safety requirements. Conclusions: when constructing a deep-laid pit without additional measures, the soil uplift is 52.5 cm, and when arranging additional measures in the form of a sheet pile – 1.97 cm, which must be taken into account when designing an above ground reservoir for irrigation as part of a system for regulating the precipitation runoff in a mountain-piedmont zone.

Мембрано-ассоциированные и секретированные экстраклеточные белки теплового шока 90 (Hsp90) играют важную роль в миграции, инвазии и метастазировании опухолевых клеток и считаются перспективной терапевтической мишенью для создания противоопухолевых препаратов антиметастатического действия. Ранее были идентифицированы пептидные фрагменты сурвивина (KHSSGCAFL) и Hsp70/Hsp90-организующего белка (KAYARIGNSYFK), которые обеспечивают связывание этих белков с внутриклеточным Hsp90. Мы исследовали влияние этих Hsp90-связывающих пептидов на миграцию и инвазию клеток фибросаркомы человека HT1080 и глиобластомы человека A-172. Hепроникающие в клетки Hsp90-связывающие пептидные фрагменты сурвивина и Hsp70/Hsp90-организующего белка не проявляли цитотоксичности и антипролиферативной активности, в то время как проникающие в клетки Hsp90-связывающие пептиды, дополнительно содержащие последовательность гомеодомена Antennapedia, были токсичны для клеток HT1080 и A-172. Непроникающие в клетки Hsp90-связывающие пептиды незначительно снижали базальную (нестимулированную) миграцию и инвазию клеток, однако выраженно ингибировали миграцию/инвазию клеток, стимулированную экстраклеточным Hsp90...

Published: August 2021

A cikk címében szereplő offenzív kiberműveletekhez szükséges képességek kialakításáról számos országban hatalmas szakmai vita alakult ki az elmúlt időszakban. Ugyanakkor az offenzív kiberműveletek alkalmazásának körülményei és azok következményeinek számbavétele ugyanolyan fontosak, mint maguk a műveletek. Ennek megfelelően jelen írás címe önmagában is sok kérdést felvet. Szükséges-e az offenzív kiberképességek kialakítása? Ez egyenlő-e a kibertámadó képességek kialakításával? Ezek a képességek milyen feltételek mentén alkalmazhatók akkor, ha egy kibertámadás mögött állami szerepvállalás áll? Része lehet-e a modern fegyveres küzdelemnek a kibertérben való támadás? Ezeket a kérdéseket igyekszik jelen írás számba venni két részben. A tanulmány első része az offenzív képességek általános hátterét járja körül, míg a második rész a képességek kialakításának feltételeit, szervezeti hátterét és az alkalmazás módjait, valamint annak feltételeit vizsgálja.

QMS in the consulting engineering industry – can we do better?
Authors: Ingason Helgi Þór , Hallgrímsson Sveinn Þór
Published: August 2021

The consulting engineering industry in Iceland has transformed itself in recent years to the extent that ISO 9001 certification has now been widely achieved. This paper explores aspects of this transformation from three different perspectives: Firstly through interviews with quality managers and executives of five engineering firms employing 80% of consulting engineers in Iceland; secondly through a survey conducted among all employees of the same engineering firms; and thirdly through interviews with representatives of five major public purchasers of engineering services in this country. The representatives and employees of the engineering consultancies are quite positive about the benefits of their ISO 9001 certification and that their experiences have surpassed their expectations. The public clients are more neutral in how they view the same topic and often seem to take certification for granted. Nevertheless, it is normally a key requirement for these public clients that companies tendering for larger projects have to have ISO 9001. Certified companies need to adapt and continuously improve their quality systems and make the benefits of this known to management, employees and clients, as appropriate.

Existing urban drainage structures that collect stormwater in underground piping networks face increased pressure with urban densification and increased rainfall intensity with global warming. Urban flooding may become more frequent in the future posing economic, environmental and health risks. Sustainable Drainage Solutions (SuDS) are increasingly being considered as a natural and economical approach to surface water management. Ponds, vegetated swales, rain gardens and green roofs slow down the surface water flow and break down pollutants stemming from traffic, asphalt wear and roof materials. SuDS has been designed for one neighbourhood in Iceland, Urriðaholt. The Icelandic Planning Act and National Planning Strategy have set the base for the implementation of SuDS. Iceland, however, lacks a comprehensive strategy to obtain the benefits of SuDS. This article presents the key success factors for implementing SuDS in Iceland, based on a review of Sweden's and England ́s decadal experience, and current legal, planning, knowledge and data environment in Iceland. Firstly, it is important to clarify the strategic goals of urban runoff management in governmental policy documents. Secondly, the implementation of SuDS needs to be intertwined with the planning process both in municipal and detailed planning phases. A collaborative effort must be undertaken between sewer specialists, planners and other professionals to develop novel surface water collection approaches with respect to local conditions. Collaboration, roles and responsibilities must be clear and identified throughout the SuDS life cycle, from strategy, planning and design, to construction, operation and maintenance. More interdisciplinary research needs to be conducted with regards to SuDS, and communicated to local stakeholders to improve their general knowledge on SuDS.
