Authors: Dziuba Szymon T. , Ingaldi Manuela , Hamplová Eva , Cierniak-Emerych Anna 
Published: March 2019

Abstract
Food safety means all the conditions that have to be met and actions that have to be taken at all stages of food production or sales to protect human health and life. Studies have demonstrated that organic food is considered by consumers to be healthier and safer than conventional food produced by means of intensive farming methods. In this context, the interest in organic food among both consumers and distributors is increasing. This means that there are many factors determining organic food production. Among them are those related to competencies that affect product safety, which represents a guarantee that the enterprise will achieve market success and is one of the sources of competitiveness for such enterprises.
Therefore, the aim of the study was to present assessment of soft competencies of laboratory employees by their immediate superiors. The problem was identified more closely as a case study of the corporation that produces organic foods, whereas assessment of competencies was compared to the specific features of the food sector the enterprise operates in, with the examples of the branches located in Poland, the Czech Republic and Romania.

Published: March 2019

Abstract
Managing quality of education is difficult and diversified task. Certainly, at the very center of quality assurance is experience that students and graduates get throughout their education course. One of the factors influencing these experiences are teaching methods. The objective of the paper is to assess the experience of Workplace Safety and Hygiene master program students of with regard to teaching and learning methods and Industry 4.0 readiness. The objective is realized through interpretation of the survey results that was made within MSIE4.0 project among the students of different industrial engineering master programs. Additionally, the program and courses documentation is interpreted in accordance to the ‘LOVE’ model approach to assess education experience. The sample of the survey is based on MSc students of Workplace Safety and Hygiene that are held at Częstochowa University of Technology. As the study shows, there are some drawbacks of the program with regard to immersive approach to learning and more active students engagement. The readiness to Industry 4.0 requirements is not really visible and some purposeful actions should be made in order to make the program part of activities addressing this economic and social challenge.

Authors: Dudek Agata , Kobyłecki Rafał 
Published: March 2019

Abstract
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

Abstract
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.

Published: March 2019

Abstract
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

Abstract
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.

Abstract
Designers have a major interest about fatigue properties of materials used in transport industry. Each component in transport works under alternating stress. From this point of view the fatigue properties are important for single parts lifetime resulting into safety of whole components as cars and airplanes what leads to safety on the roads or air and have influence on human life as well. Therefore this paper deals with fatigue properties of wrought Inconel alloy IN 718 and aluminum cast alloy AlSi9Cu3. Both materials were put on fatigue push – pull test, but Ni – based IN 718 alloy at frequency of loading around 20 000 kHz (High Frequency High Cycles Fatigue) and aluminum alloy AlSi9Cu3 at frequency of loading around 80 Hz (Low Frequency High Cycles Fatigue). These parameters were chosen with respect of usage such materials for production of components used in transport industry applications. Results after fatigue tests are presented as Wohler curve. For prediction of source of fracture the SEM fractography analysis of fatigue fracture surfaces was made.

Published: March 2019

Abstract
Shade effect is a defect of the images very often invisible for human vision perception but may cause difficulties in proper image processing and object detection especially if the aim of the task is to proceed detection and quantitative analysis of the objects. There are several methods in image processing systems or presented in the literature, however some of them introduce unexpected changes in the images, what may interfere the final quantitative analysis. In order to solve this problem, authors proposed a new method for shade correction, which is based on simulation of the image background based on analytical methods which return pixel values representing smooth grey level changes. Comparison of the effects of correction by applying standard methods and the method proposed are presented.

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

Abstract
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.

Abstract
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.

The equivalence of quasi-chemical and statistical description of adsorbate molecule association in a localised adsorption monolayer on a homogeneous solid surface
Authors: Garbacz Jerzy K. , Kozakiewicz Mariusz 
Published: March 2019

Abstract
The analysis of Berezin and Kiselev’s concept assuming linear association of molecules in a localised adsorption monolayer on the homogeneous surface of a solid adsorbent was carried out. An inconsistency due to the lack of consideration of equilibrium concentration of free adsorption sites in the formulation of the expression for the association constant has been pointed out. It was shown that the correct form of this function leads to the final adsorption equation being identical to the specific case of the Fowler-Guggenheim equation. The obtained result has been generalised to cases of branched adsorbateadsorbate associations. A new adsorption equation limiting the association to at most the dimers has been introduced. Critical conditions for the two-dimensional condensation of the adsorption layer were determined. By applying the formalism of canonical ensemble, full equivalence of the phenomenological and statistical methods was demonstrated in the description of the intermolecular interactions in the localised adsorption monolayer.
