Abstract: Our main objective was to determine the antimicrobial effects of selenium nanoparticles (SeNPs). For the testing of their influence we exploited isolates obtained from swabs from patients (n = 25) with hard-to-heal skin infections. [..] Read more

Abstract: Present conditions of highly competitive environment lead the owners and management of metallurgical enterprises to a strategic orientation on innovation, which is necessary for their durability and obtaining a significant market position. For efficient implementation of innovation activities, it is essential to compare with others and to look for ways to use the collected knowledge. [..] Read more

Abstract: The article evaluates the effect of technological parameters of machining on surface roughness, dimensional and shape accuracy in the process of milling Al2O3 ceramics in hardened state. The unique properties of ceramic materials cause more and more interest in them in various branches of industry. [..] Read more

Abstract: This paper describes experiments for the development of methods of non-destructive, non-contact surface diagnostics. This is oriented on technical systems in metallurgical operations with usage of laser scanners and digital image processing techniques. [..] Read more

Abstract: The article deals with the issue of wastes from the predominantly imported raw material sources of drawn high-carbon and low-carbon wire. The acquired knowledge is based on an analysis in a selected spectrum of branches and disciplines dealing with the processing of wire and wire products in the conditions of the Czech Republic. [..] Read more

Abstract: This paper is dedicated to financial performance evaluation of metallurgy industry of the Czech Republic. Financial performance of the industry or company is a random process, which can be decomposed into the particular indicators. [..] Read more

Abstract: The microstructure, the phase constitution and hardness of Cr-V ledeburitic tool steel Vanadis 6 subjected to sub-zero treatment with several soaking time in nitrogen vapors have been investigated. The metallurgical aspects include reducing the amount of retained austenite and increasing carbide count, so wear resistant and dimensional stability are better as compared to conventionally heat treated material. [..] Read more

Abstract: At the present time, the heat treatment process plays an important role in the production of automobile parts. This is valid especially for the transmission components. [..] Read more

Abstract: Fluxes (slag-forming additives) provide the formation of blast-furnace slag of suitable chemical composition. These additives affect not only the technological parameters of the blast-furnace process. [..] Read more

Abstract: During heat treatment of carburized steel parts, the transformation of austenite to martensite occurs and a certain amount of retained austenite remains in the hardened layers. The higher content of retained austenite in the carburized layer adversely influences hardness and frictional characteristics and increases susceptibility to fatigue damage. [..] Read more

Abstract: Strategy of steel company is usually identified with a broad program of setting and achieving organizational goals. A prerequisite for the maintenance of the enterprise in the market and shaping its development, it is initially to develop a reliable assessment of the strategic position which would allow for the preparation of such a strategy, which will fulfill the most important functions. [..] Read more

Abstract: Most manufacturing companies realize its technologies, implemented through concrete machinery parts. They differ in terms of importance, the relevance of their selection and the level of their modernity. [..] Read more

Abstract: Economics of blast furnace process, which determines the total cost of production, is one of the most important elements of management in steelworks. In the article the coke consumption from different manufacturers in the blast furnace process in chosen metallurgical plant over five years was presented. [..] Read more

Abstract: The operation of a blast furnace is characterized by simultaneous running chemical and physical processes. Hence, the influence of parameters like pressure, temperature and gas composition on the reduction behaviour of the iron bearing minerals cannot easily be presented in a simplified form, e.g. [..] Read more

Abstract: The quality of ore raw materials significantly affects the technological aspects of the blast furnace process. The comparison of iron ores is complicated because of the wide range of parameters which can be used to evaluate the ores. [..] Read more

Abstract: The use of working time of a Samp drawing machine has been assessed in the article. It has been evaluated in the process of drawing a steel wire, φ = 1.5 mm in diameter, which is applied in civil engineering. [..] Read more

Abstract: Responsible management and all-risks assessment is of crucial and key importance for every company. Harmonizing demand and offer is a real challenge for every business, yet it is even harder in today’s very insecure and quickly changing environment. [..] Read more

Abstract: The aim of this article is to identify the main risks in internal logistics processes in companies involved in metallurgical supply chains. The article also includes an initial proposal on how to work with and eliminate some risks. [..] Read more

Abstract: Electrospun PLCL nanofibrous materials produced by direct current (DC) or alternating current (AC) electrospinning are good candidates for absorbable reinforcement for cardiovascular surgery composite bandages. For an appropriate description of the fiber layers and prediction of its relevant biomechanical characteristics, the knowledge of fiber orientation in the electrospun layers is essential. [..] Read more

Abstract: The AlSi10Mg alloy is widely used to produce complex-shaped components by Laser-based Powder Bed Fusion (L-PBF); these parts, characterized by light structures and high specific strength, are currently employed in high-performance room temperature applications in the automotive and aerospace industries. However, it is important to increase the data concerning the high-temperature mechanical properties of the L-PBF AlSi10Mg alloy to spread its use. [..] Read more
