Improvement of grinding technology with vortex cooling of steels that are liable to crack propagation
Authors: Ivanova Tatiana Nikolajevna , Biały Witold , Nordin Victor 
Published: September 2019

Abstract
Complexity of grinding process and phenomena entailing it not always allow reaching required technological results, especially while machining surfaces of parts made of tough-to-machine steels, which are liable to crack propagation. Cracks can occur in these parts during grinding due to considerable temperature difference along the section, which can cause formation of high temporary internal tensile stress. Application of cooled air in grinding process exerts considerable influence over temperature decrease in cutting area. In addition, it depends not only on heat exchange, but also on properties of cold air flow. The greatest effect of temperature decrease can be reached by injection of cold air flow in cutting area with implementation of vortex effect, which occurs in swirl flow of compressed air originating in vortex tube. The study of heat generation during machining by tools with discontinuous cutting surface and vortex air cooling was carried out. Obtained thermophysical parameters of vortex air cooling (increase in speed of stream flowing, expansion degree, share of cold stream and decrease in humidity of air stream) allow reducing heat density due to growth of cooling effect in grinding zone. On the base of experimental studies we developed recommendations for choice of optimal grinding modes by tool with discontinuous cutting surface and vortex air cooling of flat parts made of steels being liable to cracking.
Application of selected methods of multicriterial assessment in the selection process of equipment used at the extraction face – case study
Authors: Korban Zygmunt 
Published: September 2019

Abstract
Making decisions is a process that involves taking into account n acceptable variants of undertaken actions in view of m adopted assessment criteria and selecting the optimal variant (optimal variants). Due to the number of alternatives being assessed and the number of considered criteria, more and more frequently mathematical methods are used in this process. Basing on the example involving the selection of a mechanized longwall complex, the article presents the application of selected multicriteria methods: in the case of quantitative features – Hellwig's development measure method, and in the case of qualitative features – Promethee II method. In the case of Hellwig's development measure method, equipment variants were interpreted as points w in the multidimensional space, and then the distances between them and the point Po (perfect solution) were determined. In the case of the Promethee II method (discrete multicriteria decision support method), the equipment variants were compared with each other in pairs, which made it possible to determine the so-called net flows Φ(i). The obtained synthetic values mi and Φ(i) allowed to build rankings of equipment variants (objects) and to indicate the optimal variant.

Authors: Szeleziński Adam , Murawski Lech , Muc Adam 
Published: September 2019

Abstract
Among structural health monitoring (SHM) methods of thin-walled structures, a vibrodiagnostic method is one of the most promising. The accelerometer recorded responses provide diagnostic information that requires mathematical processing to extract the essential dynamic characteristics. The authors have been looking for new parameters - diagnostic benchmarks which can be applied to non-destructive, automatic testing of thin-walled marine structures (especially their welded joints) like ship hulls. All characteristics have been based on recorded data generated during the vibration tests of welded joints with and without failures. For this purpose, the authors proposed method based on: FFT windowing analysis, benchmark with using 2D or 3D time – frequency dynamic characteristics and the determination of damping decrement in function of time. The work presents the algorithm and exemplary results obtained from the application of proposed method to several selected sample plates with different type of welds.

Abstract
Hard coal mines and mining enterprises involved in hard coal exploitation in the area of the Upper Silesian Coal Basin (Górnośląskie Zagłębie Węglowe) are characterised by the presence of natural hazards typical of this type of exploitation. These hazards include the risks related to methane, coal dust explosion, endogenous fires, as well as rock burst and caving of roof rocks. The article presents the results of a taxonomic analysis aimed at determining the similarity of hard coal mines and mining enterprises in Poland in terms of the dangerous incidents caused by the risks related to methane, coal dust explosion, endogenous fires, as well as rock burst and caving of roof rocks. The analysis was carried out for the 2008-2018 data and encompassed a total of 26 hard coal mines and mining enterprises located in the Upper Silesian Coal Basin. The analysis was performed using the k-means method of non-hierarchical clustering. The main objective of the article was to determine homogenous groups (clusters) of mines exhibiting the greatest similarity in terms of dangerous incidents caused by the activation of natural hazards in the years 2008-2018. These data can be successfully used for the development of preventive measures and risk analyses for these enterprises.

Authors: Janik Agnieszka , Szafraniec Marek 
Published: September 2019

Abstract
The transition from the linear model to the circular economy (CE) model is not an easy task and it requires constant monitoring of the achieved effects. Taking this fact into consideration, in January 2018 the European Union (EU) set 10 indicators to monitor and evaluate the main elements of the circular economy in the EU and its Member States. The list of indicators is short and it is based on the use of current available data. The monitoring results are intended to constitute the basis for setting new priorities towards the long-term goal of the circular economy. In case of companies there is still no framework for monitoring the effects of circular economy at micro level. In practice, various indicators for circularity assessment at micro level are available, but each of the indicators evaluates the complexity of circular economy to different extent. For this reason, there is a need to create a framework for monitoring the circular economy at company level, which would also be based on information already collected by the companies for the preparation of various environmental reports. Therefore, this article presents the results of review 66 environmental statements, which are prepared and updated annually by organizations participating in the Eco-Management and Audit Scheme (EMAS) system in Poland. On this basis, it was determined what circular economy information are already collected and reported by the companies and which information can be included in the framework of circular economy monitoring at company level in the future.
SHI irradiation induced modifications of plasmonic properties of Ag-TiO2 thin film and study using FDTD simulation
Authors: Sharma Himanshu , Singhal R. 
Published: September 2019

Abstract
Modifications in morphological and plasmonic properties of heavily doped Ag-TiO2 nanocomposite thin films by ion irradiation have been observed. The Ag-TiO2 nanocomposite thin films were synthesized by RF co-sputtering and irradiated by 90 MeV Ni ions with different fluences. The modifications in morphological, structural and plasmonic properties of the nanocomposite thin films caused by ion irradiation were studied by transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV-Vis absorption spectroscopy. The thickness of the film and concentration of Ag were assessed by Rutheford backscattering (RBS) as ~50 nm and 56 at.%, respectively. Interestingly, localized surface plasmon resonance (LSPR) appeared at 566 nm in the thin film irradiated at the fluence of 1 × 1013 ions/cm2. This plasmonic behavior can be attributed to the increment in interparticle separation. Increased interparticle separation diminishes the plasmonic coupling between the nanoparticles and the LSPR appears in the visible region. The distribution of Ag nanoparticles obtained from HR-TEM images has been used to simulate absorption spectra and electric field distribution along Ag nanoparticles with the help of FDTD (Finite Difference Time Domain). Further, the ion irradiation results (experimental as well simulated) were compared with the annealed nanocomposite thin film and it was found that optical properties of heavily doped metal in the metal oxide matrix can be more improved by ion irradiation in comparison with thermal annealing.

Abstract

Introduction. Nowadays, a professional image is an important element of the identity of individual professions. Its formation is a difficult process, dependent on many factors, including the use of new communication channels, such as social media, which in recent years have become a space for expressing social opinion, including those concerning individual professions.

Aim. The analysis of the possibilities of using social media in shaping the image of nurses on the Internet.

Material and methods. The study was carried out using the comparative method. The subject of the research were websites (fanpages) related to the professional environment of nurses on the social networking site Facebook.com, chosen deliberately according to the adopted criteria.

Findings. During the research, differences in the strategy of administering the analyzed websites were identified, depending mainly on the subject matter and purpose of publishing the content. The topicality, visual attractiveness and cohesion were characterized by a high level. The posts appearing on individual websites were written in the language of the recipients, with different publication frequency. The websites created a long-term group of recipients and tried to influence the image of nursing in Poland in a positive way.

Conclusions. Content published on social media can affect both the positive and negative image of the nurse in the public opinion. Among the factors that do not affect the image of nurses can be indicated, among others, offensive language of comments and displaying negative traits of nurses. Positive reception guarantees current knowledge in the field of nursing and emphasizing professional competences.
