Abstract: In this paper, we report the optimal conditions for the isolation of amino acid arginine from different types of matrix, such as blood, plasma or tissue and their characterization using ion-exchange liquid chromatography with VIS detector. Paramagnetic microparticles able to isolate and immobilize amino acid arginine were prepared and used to preconcentrate arginine for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

Abstract: Sarcosine is an amino acid that is formed by methylation of glycine and is present in trace amounts in the body. Increased sarcosine concentrations in blood plasma and urine are associated with sarcosinemia and some other diseases such as prostate cancer. [..] Read more

Abstract: Metallurgical supply chain consists of raw materials miners, transport, integrated metallurgical enterprise, service centers and local distributors. The overall performance of the supply chain which is subject to disruption from the environment is dependent on performance of its links and its ability to recovery after such event or resilience, respectively.

Abstract: The paper contains results of studies on the formation of oxide layers on 13CrMo4-5 steels long-term operated at an elevated temperature. The studied steels were operated at the temperature of 380 °C for 130,000 h (steel 1) and 535 °C for 230,000 h (steel 2). [..] Read more

Abstract: In this study the effect of notch angle on fracture toughness (KIC) of AISI 4340 steel is investigated by using circumferentially notched bar method. The specimens have three different notch angles 45°, 60°, 75° and specimen diameters (D) – notch diameters (d) ratio (D / d) keep constant as 1.2. [..] Read more

Abstract: The article presents the research results on acoustic emission (AE) generated by process of friction stir welding of sheets made of dissimilar aluminium alloys (AW-5083 and AW-7020). Nowadays acoustic emission method is used in many fields of science, including in the diagnosis of machining and joining processes such as turning, grinding, milling, welding, etc.Friction Stir Welding (FSW) – a new technology can be successfully used for butt welding of different types of aluminium alloy sheets.

Abstract: The article deals with the study of verification and evaluation of selected mechanical properties of stainless steel 316L (1.4404) after the production of additive technologies (3D printing) by Selective Laser Melting (SLM). For the purpose of the experimental testing were printed two sets of samples from the powder metal by the laser-sintering process at different process parameters. [..] Read more

Abstract: Fracture toughness (KIC) is the one of the most important parameters for evaluating the fracture resistance of the machine elements or structural parts subjected to cyclic loading. These cyclic stresses can cause damage or premature failure. [..] Read more

Abstract: Carbide coatings prepared using the HP/HVOF technology are widespread and commonly used surface treatment. These coatings provide various advantages compared with the substrate material and are able to supply top mechanical and corrosion properties at a low cost. [..] Read more

Abstract: Deoxidized High Phosphorus (DHP) Copper tubes are frequently used in numerous industrial and household applications. To ensure the acceptability of DHP copper tubes prepared by various industrial processes, the quality of the DHP copper tubes must be evaluated. [..] Read more

Abstract: CastNode platform is a knowledge base dedicated to casting technology and foundries. Applications database (the InnoCast) integrates four components of knowledge: (1) foundries and supplier base, (2) the base of innovations in the field of casting, forging and rolling, (3) database of publications and (4) patents for casting techniques and products. [..] Read more

Abstract: One of the types of production employed at metallurgical plants is serial production. Serial production is applied for products that have steady demand, are homogeneous and can be delivered to more customers. [..] Read more

Abstract: Effective operation of business logistics processes is the main aim in the majority of companies acting in various industries where mechanical engineering is no exception. For the correct operation of the production process is necessary to carry out quality analysis for its implementation can be used a wide range of methods and tools. [..] Read more

Abstract: With the development of computers and software products, the importance of the use of quantitative methods for managerial decisions has been growing even when it comes to industrial companies. Decision making represents one of the most important managerial activities, which managers have to adopt on an everyday basis when conducting their work. [..] Read more

Abstract: Metal casting is one of the most important manufacturing process technologies and is defined as a process in which molten or liquid metal is poured into a mould. Today, metal casting components are found in over 90 percent of manufactured goods and equipment, from critical component for aircraft and automotive industries to home applications as well as construction machineries. [..] Read more

Abstract: The approach of the most common industry-specific FE-systems for the service life evaluation of forming tools holds some disadvantages. For example, within the decoupled tool analysis, load situations are typically analysed at room temperature and thus, the transient temperature development in the forging die is not considered in the lifetime evaluation. [..] Read more

Abstract: Förster resonance energy transfer (FRET) is an energy transfer process between a pair of light-sensitive molecules, where the donor fluorophore (initially in its electronic excited state) transfers energy to an acceptor chromophore. In this study, FRET was used to investigate the dimerization of metallothionein isoform MT-1A. [..] Read more

Abstract: One of the basic factors influencing the good results of any production system is the optimal organization of the production process so that the use of machines is as effective as possible. One of the methods of assessing the use of machine working time is the PAMCO (Project Analysis and Monitoring Company) method. [..] Read more

Abstract: The paper deals with the issue of capacity balancing at the operational level of production management. The authors focused on the possibilities of supporting planning and decision-making processes, where they provided planning staff (production planners) with measures to gradually balance the production schedule in relation to the available production capacities. [..] Read more

Abstract: In this work, we consider the possibility of obtaining bimetallic W/Cu nanoparticles (NPs) by means of a magnetron-based gas aggregation source (GAS) of NPs. For this, a GAS of original construction was equipped with a segmental target consisting of two metals: tungsten and copper. [..] Read more
