Recently, there has been a large development of photovoltaics in Poland and in the world. This work shows how the energy profit of a high-power photovoltaic farm changes with the change of the angle of inclination of the panels on the example of a PV power plant project in the Siemiatycze districtin the Podlaskie Voivodeship. In order to verify the energy gain, measurements were made in the PVSyst program for panels with a power of 600 Wp, the spacing of 10 m or 6 m for angles from 20 ° to 25 °. Based on the analysis, the results were obtained, which indicate that with an increase in the angle of inclination in the studied range of angles, the annual production of energy by power plants increases. The difference between the production for the angle of 20 ° and the angle of 25 ° is 1010 MWh, which means profits higher by almost 1% per year. on the basis of the selected row spacing and angle, an analysis was carried out, which shows that the average amount of energy generated in a 140 MW installation will be approximately 149 246 MWh. The article also contains an analysis of losses which are generated during the work of PV panels.

In the life of every person, there are a number of values that guide them. These values are reflected both in private and professional life, and sometimes they smoothly interpenetrate. In the hierarchy of values related to professional work, work safety should rank among the highest. However, the number of accidents in Polish enterprises leaves no illusions, and the causes of these accidents indicate the main source of their occurrence, which has undoubtedly been the human factor for many years. This paper presents the results of surveys conducted in the SME sector regarding the place of work safety in the hierarchy of values related to professional work in the opinion of employees.

            <description><![CDATA[

The paper presents the results of qualitative analysis and improvement of the printing process with UV inks on glass packaging with the use of selected quality management tools and methods. The research was carried out in a glass factory located in the Silesian Voivodeship in Poland. The qualitative analysis included the risk assessment related to the printing process with UV inks, print quality, and the type of nonconformities occurring during printing. Based on the conducted analyses, proposals for improving the printing process with UV inks were determined. As part of the analyses, such methods and quality tools as fault tree, FMEA analysis, Pareto-Lorenz diagram, and tree diagram were used. It was found that the most common nonconformity of printing with UV inks on glass packaging is smearing of the emulsion covering the glass vessel and that most of the nonconformities resulted from errors made by employees, which were caused by non-compliance with the instructions for individual activities by people employed in production positions and quality inspection employees. It was proposed to implement employee training at individual workplaces, in particular the implementation of instructions for performing specific activities, as well as the introduction of additional employee supervision and implementation of changes in the management of the printing process and quality inspection of the decorated products.

            <description><![CDATA[

The need to save energy, as well as the constant tightening of regulations regarding thermal protection of buildings force the need to look for solutions increasing the thermal performance of building envelopes. One of the important issues in this regard is the appropriate thermal insulation of usable attics. Currently, two layers of mineral wool are most often used - one between the rafters and the other under the rafters. Recently, an alternative solution has emerged, namely PIR (polyisocyanurate) foam over-rafter roof insulation systems. The aim of the article is to assess the legitimacy of using this new method of roof slope insulation. Appropriate conclusions were formulated on the basis of the technical and economic analysis of PIR foam parameters and other insulation materials, and a case study in which one of the actual implementations of the over-rafter insulation was analyzed. It was found that the use of PIR panels as the external insulation of roof slopes gives benefits primarily in terms of improving the quality of thermal insulation works. The over-rafter system is easier to implement than the classical solution (fewer possibilities of assembly errors), and above all, it minimizes thermal bridges. In addition, PIR has a better thermal conductivity than mineral wool, which reduces the necessary insulation thickness, and the possibility of condensation inside the envelope and cold air infiltration is also limited. The barrier to the use of this solution is currently primarily the high price of PIR roof panels, but as shown, the benefits associated with improving the quality of insulation are taken into account and encourage investors to choose such a solution.

Ensuring the process capability currently means the warranty, that produced products will be in accordance with requirements - from company´s side or from customer´s side. This study focuses on the statistical control of flange shaft process capability by serial production in company focused on products for automotive. The flange shaft process is evaluated by control charts, specifically by control chart for average and range (x̄, R). As the results showed, based on diagram for average and range we are able to say that the turning process is under the statistical control. Also, we had finished the reguest for capability of process, where the indexes of capability process Cpk1 and Cpk2 are higher than the determined value on 1.33 point. The normality of the measured values was verified by histogram. Obtained values are: Cpk1 = 1.645 a Cpk = 1.52. Therefore, we can consider the process as capable.

The heating sector, which accounts for half of the EU’s final energy consumption, still relies heavily on fossil fuels. This results in the emission of greenhouse gases and other pollutants into the atmosphere. For this reason, the European Union has, for several years, been pursuing a climate and energy policy which, in the area of district heating, is intended to make it more efficient and sustainable. This means introducing low-carbon technologies and reducing fossil fuel consumption in favour of renewable energy sources. Modern efficient district heating systems should guarantee a reliable heat supply while reducing environmental impact. The article discusses the main factors important for the sustainable development of district heating. The potential and importance of the heating sector in the European Union member states was presented. Then, the factors affecting the development of this sector are shown and the directions of transformation of district heating systems with the use of renewable energy sources are discussed. It also presents the current structure of fuels consumed by the district heating sector in Europe and its projected development with the use of high-efficiency cogeneration and various renewable energy sources.

Currently, research on materials containing magnetic magnetic particles give opportunity to the prepare and study of composites with interesting magnetic features. One possibility for producing such materials is the use of fillers with magnetic properties. The final properties of such composites depend mainly on characteristic polymer matrix. However, the addition of magnetic materials arose use of new technologies. Such builders include the magnetic ferrites. Metal hexaferrites represent well researched group of magnetic materials (Mallick, 1993). Their high values of magnetocrystalline anisotropy and saturation magnetization enable widespread application of these materials as permanent magnets. Low price and excellent chemical stability with suitable magnetic characteristics classified ferrites to one of the most important magnetic materials (Rigbi, 1988).
The experimental material used was a composite formed by combining a polymer matrix (linear polyethylene HDPE), and the hard-magnetic strontium ferrite labeled FD 160S as a filler. Composites with different filler contents were prepared from the starting materials. The dependence of viscosity on the content of ferrite filler was determined by rheological measurements.

Value Stream Mapping (VSM) is a visual Lean Manufacturing tool for graphically illustrating material and information flows in processes, on production lines, and even across a factory. It makes it possible to identify activities that do not generate added value, and thereby creates opportunities for improvement by reducing or completely eliminating waste. This paper explores a real-work case study of the production process for an air handling unit. Thus, after analysing the activities undertaken in an enterprise operating in the HVAC (Heating Ventillation Air Conditioning) industry, a current state map was drawn that shows the actual flow of the value stream. Then, a future state map was developed with suggestions for eliminating the root causes of waste and those for improving processes. The proposed improvements allow for shorter lead time and faster order processing, which may increase competitiveness.

Cr-Ni-Mo stainless steels are susceptible to the pitting in aggressive chloride environments. One of the possible ways for the influence of their corrosion behavior is the use of inhibitors as the chemical modification of the environment. The resistance of AISI 316Ti stainless steel to the pitting with/without the inorganic inhibitor was tested by two independent corrosion tests: 24-hours exposure immersion and potentiodynamic polarization test. Both tests were carried out in 1M chloride acidic solution with/without 0.1M molybdate inhibitor at room temperature. Results of immersion tests were evaluated by the corrosion rates calculated from corrosion losses and by the morphology of the pitting. Potentiodynamic polarization curves were evaluated by the pitting potentials.

            <description><![CDATA[

The COVID-19 pandemic has had a significant impact on personal and professional lives of people around the whole world. Numerous enterprises were forced to limit their activities. However, the employees of certain industries, performing work necessary for the normal functioning of the society, have been constantly exposed to epidemiological threats. The construction industry is an example of this. The ongoing threat of the pandemic could have had a significant impact on the workers’ behaviour and perceptions of safety. The work safety culture could have undergone such a change. The main purpose of the article was to determine whether the pandemic influenced the work safety culture in the construction industry. The methodological tool applied was a questionnaire addressed to people who directly supervised work on construction sites. The survey was conducted among 49 Polish enterprises operating in the Silesian Province. The results of the research indicate that the COVID-19 pandemic has caused changes in the work safety culture, most of which were positive. An analysis of the litera-ture on the impact of the COVID-19 pandemic on the safety of workers indicates that publications in this area are primarily aimed at representatives of healthcare, while there are few publications on changes in the area of health and safety in the construction industry. This paper is an attempt to fill this research gap.

Work safety is an autotelic value. The health and life of the employee should be a priority in any work process. The risk of loss of health and life is a frequent phenomenon in manufacturing enterprises. According to the data of the Central Statistical Office, in the first half of 2020, approx. 24 thousand people who were injured in accidents at work were reported to the office. Approximately every third of these accidents is related to a manufacturing company. The SME sector generates the largest number of accidents at work. The results of the survey concerning opinions on the risk of losing health and life at work are presented in this article. The survey was conducted among employees of the SME sector, with particular emphasis on manufacturing companies. The results presented in the article represent only a part of the larger picture.

This paper presents the results of soil testing in selected sites of Ostrava city. Soil samples were collected from nine parks in Ostrava from three different depths using a drill. The sites from which the samples were collected are areas near trees and open space. Each of them is located in a different part of the city and is affected by different types of pollution. Soil is one of the resources that very often cannot be reclaimed. This process is spread over time, and restoring land to public use without negative human impact is very costly and long-lasting. The analysis will allow to determine the impact of mining operations on soils in selected places of Ostrava city. The results are compared with the maximum permissible concentrations of harmful elements according to the Regulation of the Ministry of Environment on land protection.

This paper discusses the opportunities for reducing the emissions of substances dangerous to the environment as a result of switching from traditional ferry drives to electric propulsion systems. The research carried out included the analysis and evaluation of the technical solutions that are currently used in mixed passenger/vehicle vessels operating in the Baltic Sea Region (BSR). A comparative analysis of the impact of internal combustion engines and environmentally-friendly alternatives was also performed. The objective of the paper was to analyse and evaluate the organisation of ferry services in the BSR in the context of the propulsion systems used in ferries. The technical solutions currently used in the vessels under review were identified, as well as the possibilities offered by electric propulsion.
