Authors: Gryniewicz Marcin , Szlendak Jerzy K.
Published: March 2019

In this paper, the results of a research on thin-plate single-lap connections are presented. Such type of connections is popular in steel roofs made of trapezoidal plates and other thin-walled elements. In case of a building safety it is necessary to ensure that materials with proper durability and ductility are used. Connections are one of the most important components in such structures, particularly when in-plane strength of a roof is taken into account. So far, in many existing regulations, only general calculations of such connections are conducted. However recently, discrete and computational methods can be used to build new, expanded mathematical design models, such as those presented here. Such models could be useful in an advanced design where a static analysis is combined with the safety assessment of the connections in a structural system. This is difficult when sheeting is utilized as a structural in-plane shear diaphragm. These require to take into consideration the important interactions of structure with covering and covering with another covering elements. The research is an effect of authors works on practical design approaches. Such methods can be effectively used for structural designs of buildings where the stressed skin diaphragm action is involved. Finally, practical input values about connections can be acquired from the presented data.

Authors: Wrzalik Artur , Jereb Borut
Published: March 2019

The today’s change in climatic conditions results in weather phenomena occurring increasingly more frequent in Poland that can lead to crisis situations. Also the growing number of high or increased risk of serious industrial failure establishments causes greater probability of adverse and harmful effects for the environment and the population. A response to the need for minimization of those and other threats is effective crisis management. This management should be supported by IT solutions. The paper proposes to use a selected artificial intelligent method - expert systems - in the crisis management process. An expert system is a computer program adopting the knowledge and reasoning mechanisms to solve problems that require experience and expertise. The idea of expert systems is to transfer the knowledge held by a domain expert into a knowledge base, which is applied by the reasoning mechanism. The article presents some results from surveys carried out in selected local government entities of the Silesian voivodeship as regards the interest in implementation of artificial intelligence in the discussed field, and proposes an expert system for a particular crisis situation.

Published: March 2019

Currently, a very big problem of cities in Europe and the world is air pollution with combustion products of car fuels, generation of heat and electricity. These impurities affect the microclimate of cities significantly. Pollution not only affects the area outside buildings, but getting into their interior through ventilation systems, which has an adverse effect on the indoor environment of buildings. High concentrations of CO
2, cause a weakening of concentration in working people, which affects the deterioration of safety and work efficiency. For assessing air quality improvement on “green roofs”, a field study of CO
2 content has been carried out on the “green roof” of a four-storey building, on a completely identical non-greened building, and on a highway with high-density traffic near them in Kiev. It was found that greening the roof significantly reduces the CO
2 content from 501 ppm on the road and 452 ppm on the roof without protection to 410-415 ppm. It improves the conditions in which people work and rest.
The Use of Thermovision in the Monitoring of Coal Storage Facilities as an Element of Safety Management in the Warehouse Management
Authors: Sobocińska Anna , Sobociński Maciej
Published: March 2019

Spontaneuos combustion (or self-ignition) is the initiation of the burning process without an external source of ignition, such as a flame or spark. This phenomenon often occurs during storage of such substances as hay, straw as well as coal or culm. Like any other type of fire, in addition to potential material losses, it also poses a threat to people. Thanks to the systematic monitoring of landfills using a thermal imaging camera, the dangerous effects of this phenomenon can be avoided. The article presents photos taken on a coal storage site where, as a result of both prolonged heat and wind exposition, a self-ignition phenomenon occurred that was detected early due to the use of thermovision.

Authors: Deja Agnieszka , Dzhuguryan Tygran
Published: March 2019

A multi-floor manufacturing in residential districts of huge city promotes decongestion of urban traffic and satisfy the population’s demand for essential goods. City manufacturing and its supply chain entail several challenges related to the sustainable development of a large agglomeration. Environmental problems impose significant constraints on such manufacturing activities and production waste in the urban environment poses a real problem that needs to be addressed by special research. This paper discusses integrated sustainable production waste management for a city multi-floor manufacturing cluster, consisting of a group of production buildings and a supporting logistics node. In line with the theory of integrated sustainable waste management, three key components are addressed: waste management stakeholders, components of the waste management system, and the technical, environmental and legal aspects of a city multi-floor manufacturing cluster. The goal of the paper is to develop a concept for a model of environmental sustainable waste management in a city multi-floor manufacturing cluster, aimed at ensuring the system safety: human - technical facility - environment. This model can serve as a basis for the development of appropriate logistics chains for production waste management considering their hazardousness indicator. The versatility of the model will allow it to be widely used, and when its stages and working principles are embedded in the practice of city multi-floor manufacturing, proper control over the waste management process can be achieved. The application of the proposed model of integrated sustainable production waste management in the practice of the city multi-floor manufacturing clusters will contribute to the environmental sustainability of its operation.

Authors: Pabian Arnold
Published: March 2019

Environmental safety management contributes to sustainable development. Sustainable development is a consequence of global ecological and social threats. The natural potential of the Earth is running out, which is confirmed by worsening indicators of Living Planet Index and Ecological Footprint. Acceleration of sustainable development is particularly important to production enterprises. Production enterprises use the majority of the world’s non-renewable resources and they are largely responsible for environmental pollution. The negative influence of the enterprises on the environment can be stopped by transforming them into sustainable enterprises. Sustainable top managers should play a key role in this process. Sustainable top managers constitute a new currently emerging category of leaders. They possess knowledge and experience in both management as well as sustainability. Their features include social and ecological sensitivity, innovation and the ability to convince and motivate employees within the scope of sustainable development as well. Their objective is to create an organization whose mission, strategy and operational action programmes include ecological and social initiatives. Due to this, sustainable development is becoming an important and permanent element of enterprise functioning. Sustainable leadership constitutes a key challenge for top managers which they should accept for the benefit of future generations. The support of environmental safety management by sustainable top managers promotes its implementation in enterprises thanks to their knowledge and ecological sensitivity as well as engaging in sustainable development.

The purpose of the publication is to determine the level of consumer awareness regarding the knowledge of quality marks and food safety awareness in the aspect of purchasing decisions. The research covered a group of 51 respondents who were residents of the Silesian Voivodship. On the basis of literature research and analysis in the field of food quality and safety, the following hypothesis was formulated: By using generally known management methods, we can determine the degree of consumer awareness in terms of quality labels and food safety in the aspect of purchasing decisions. The research was conducted on a quarterly basis in 2018 based on a questionnaire (CAWI - Computer Assisted Web Interview). The results of research and their analysis have shown that consumer awareness regarding the awareness of quality marks increases, however, there is still a great need to build consumer awareness regarding the existence of quality marks and information that they provide to the consumer in terms of both quality and food safety. Research has shown that consumers are aware of the quality marks existence, but their knowledge about familiarity is still too small. It was shown that consumers, when making purchasing decisions, pay attention to product quality, price, quality certificate and ecological certificate. The factor that determines the safety of the product according to consumers turns out to be its composition. Consumers showed in research that they will not buy a product that has palm oil, sulfur dioxide, glucose-fructose syrup and aspartame.

Influence of the Environment on the Operational Safety of a Fluidized Bed Boiler
Authors: Dudek Agata , Kobyłecki Rafał
Published: March 2019

The use of fluidized bed boilers in modern power engineering is a promising solution for clean and economically acceptable combustion of various fuels, including coal, biomass and waste, for the generation of electricity. The fluidized bed boilers are nowadays technically advanced and complex combustion facilities where all individual boiler elements are subjected to withstand continuous structural and thermal loads during their operation. Intensive loading of boiler elements can be quite easily linked with boiler operational safety and is quite often one of the main reasons for emergency shutdowns followed by necessary replacements of the damaged items. In case of industrial large-scale circulating fluidized bed boilers the frequency of unplanned shutdowns is also quite often affected by the hydrodynamics of the fluidized bed and some other parameters, such as the intensity of solids circulation, temperature, solids concentration, flue gas composition and velocity, solids accumulation and deposition, as well as the corrosion or erosion of heat transfer surfaces. The present paper briefly reports the results of authors investigation focused on the morphology and structure of some chosen elements (steel anchors) sampled from one of Polish circulating fluidized bed boilers. The anchors were degraded during boiler operation and lost their mechanical durability. In order to determine the reasons of anchors’ degradation chemical composition of the elements was determined with the use of a spark spectrometer SPECTROLAB and sample morphology was investigated with JEOL JSM-6610LV scanning microscope equipped with LaB6 cathode.

Fatigue Properties Of Nodular Cast Irons Alloyed By Si, Mo And Cu
Authors: Vaško Alan , Krynke Marek
Published: March 2019

In recent years, the research of nodular cast iron has been focused on increasing fatigue resistence. In the paper, two types of alloyed nodular cast irons have been investigated – SiMo-nodular cast iron alloyed by 4% of silicon and 1% of molybdenum and SiCu-nodular cast iron alloyed by 4% of silicon and 1.5% of copper. SiMo-nodular cast iron is suitable for high-temperature applications, for example the exhaust manifolds of the combustion engines. SiCu-nodular cast iron is used in various components of tribotechnical units. These components are often loaded by fatigue. The mechanical and fatigue behaviour of both nodular cast iron types has been studied by means of tensile test, impact bending test, hardness test and fatigue tests. Fatigue tests were realised at low frequency cyclic push-pull loading up to 10 million cycles. The relationship between the amplitude of stress and number of cycles to failure was investigated and the fatigue strength was determined. Mechanical and fatigue properties of both nodular cast iron types are correlated with the microstructure of specimens.

Authors: Lazić Vukić , Arsić Dušan , Rakičević Milorad , Nikolić Ružica , Uhričik Milan , Hadzima Branislav
Published: March 2019

Steels of the ARMOX class belong into a group of the fine-grained, increased strength steels, which are manufactured by the quenching and low-tempering procedure, with intensive thermo-mechanical treatment at high temperatures. Combination of the heat and mechanical treatments provides for the fine grains and exceptionally good properties of these steels, while the low-tempering enables relatively high hardness and good ballistic properties. This is why the welding of these steels can negatively affect the material properties in individual zones of the welded joint, what could lead to worsening of the material's ballistic properties, as well. The model plates were welded with the specially prescribed technology; the joints were the but-joint, corner joint and the joint with the shielding plate. In this paper are presented results obtained from the ballistic tests of the plates welded by the prescribed technology; tests consisted of shooting with three types of live ammunition at different types of the welded joints.

Authors: Markovičová Lenka , Zatkalíková Viera
Published: March 2019

A composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Modern composite materials are usually optimized to achieve a particular balance of properties for a given range of applications. Composites are commonly classified at two distinct levels. The first level of classification is usually made with respect to the matrix constituent. The major composite classes include organic – matrix composites (OMC's), metal – matrix composites (MMC's), and ceramic – matrix composites (CMC's). The OMC's is generally assumed to include two classes of composites: polymer – matrix composites (PMC's) and carbon – matrix composites (Peters, 1998). The composite material used in the work belongs to the PMC's and the composite is formed by the polymer matrix – rubber (sidewall mixture). As filler was used hard-magnetic strontium ferrite. Composite samples were prepared with different filler content (20%, 30%, 40%, 50%). Testing of polymer composites included: tensile test, elongation at break, hardness test and study of morphology.

Authors: Baryshnikova Natalia , Klimecka-Tatar Dorota , Kiriliuk Olga
Published: March 2019

Trade in agricultural products is one of the most dynamically developing segments of the global market. The feature of the contemporary stage of world food trade development is that the leading exporters are also the largest food importers, combining the benefits of the international division of labor with the development of domestic agricultural production. In the paper, the role of foreign trade in ensuring food security has been evaluated by comparing the global index of food security and the share of imported food in the domestic market. As a result, the countries of the world have been divided into 4 groups. The first two groups include countries that ensure their citizens a high level of food security through imports, as well as or through their own efficient agricultural production. The third and fourth groups include countries which are not agrarian developed. The problems of hunger and malnutrition in these countries can potentially be solved with the help of foreign trade and increased efforts of the international community.

Published: March 2019

Ensuring transport safety is one of the key areas of transport companies’ operations. Management and organization processes not only in the intermodal transport are associated with decision-making in regard to adequate load securing, which is exposed to the inertia forces resulting from the movement of transport means. Regardless, the responsibility of individual entities in the process and the applicable insurance, the basic aspect to ensure transport safety is the correct securing of the cargo. In the article, the authors present elements of calculation models for different methods of securing cargo. Calculations were performed for the selected type of load on the specific semi-trailer meeting the requirements of the XL Code adapted for intermodal transport. The analysis of safety management in transport in the aspect of decision-making about the method of securing the cargo was also made.

Authors: Pal Priyanka , Yadav Kuldeep , Kumar Krishan , Singh Narender
Published: March 2019

The experiment was conducted in anti-insect net house for three consecutive years (2013–2016) with the goal of improving the growth and biochemical contents in two F1 cultivars of cucumber, ‘Sevenstar’ and ‘KUK 9’. Treatment was given in the form of foliar spray containing different concentrations of gibberellic acid (GA3) [0.005 g·dm−3 (G1), 0.01 g·dm−3 (G2), and 0.015 g·dm−3 (G3)] and potassium [1.0 g·dm−3 (K1), 2.5 g·dm−3 (K2), and 5.0 g·dm−3 (K3)] alone and as combinations. All the treatments significantly enhanced plant growth and yield over control. The combination K2G2 showed a marked increase in growth parameters (leaf area, flower number, total dry matter production, growth rate, net assimilation rate) and biochemical attributes (total sugar content, starch, protein). The cultivar ‘KUK 9’ had more increased parameter values than the ‘Sevenstar’. This study provides a direct evidence of the beneficial role of the application of potassium and gibberellic acid on growth, biochemical attributes, and yield of cucumber.
