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: Heavy metals are widely used in a range of materials including paints, motor vehicles, guns, and electrical components. After discarding such materials, the metal ions after dissolution can penetrate to the environment and are toxic to plants, organisms, and humans. [..] Read more

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: Flexible strain sensors based on MWCNTs/epoxy nanocomposite coated on a polyimide (Kapton HN) substrate are often preferred due to their outstanding properties. Nevertheless, polyimide has a poor adhesion with different classes of materials, such as ceramic, polymers and metals, caused by its hydrophobic nature and low specific surface energy.

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: All metal products that operate under high loading conditions are subject to wear over time. Therefore, there is a need to restore the geometric shape of the working parts after the consumption of the product life. [..] 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: Galvanizing is an application of a zinc coating on the steel base material by electrolytic deposition. Zn coating protects anodically the base material (typically unalloyed or low-alloy steel) against corrosion. [..] 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: Increasing demands for reducing the surface roughness of components impose high requirements for finishing operations. As a result, it creates a space for the application of new progressive methods for the surface finishing of components. [..] 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: The spent auto catalytic converters are a valuable source of platinum group metals (PGM metals), such as platinum, palladium and rhodium. There are two main types of structures used in construction of catalytic converters –ceramic or metallic carrier. [..] 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: A number of domestic and foreign companies have long been struggling with the problem of storage and supply. Warehouses are an important part of the logistics chain as a link among the supplier, the manufacturer and the final consumer. [..] 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: 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: The growing interest in biodegradable products paves the way for the safest sustainable earth. Starch is an extensively studied, cost-effective, easily accessible, and highly trusted resource to produce biodegradable products in the present and future. [..] Read more

Abstract: In this contribution the ceramic nanoparticles, BaTiO3 (BT), were successfully and controllably coated with two monomers, poly(butyl acrylate) (PBA) and poly(methyl methacrylate) (PMMA) using SI-ATRP approach. The presence of the polymers on the surface was investigated using FTIR and TGA techniques. [..] Read more

Abstract: One of the most popular algorithms for solving the permutation flow shop scheduling problem (PFSP) for the makespan minimization criterion is the NEH algorithm. Many research papers have been devoted to the NEH algorithm and its improvements. [..] Read more

Abstract: The extensive studies in nanoscience in the last decades are dedicated to the development of new protocols for the preparation of nanoparticles (NPs) with controlled size and shape. The dimensions and steric parameters influence the reactivity, catalytic, electrical, and optical properties and define the application of NPs in various fields: catalysis, sensing, medicine, electronics, etc. [..] Read more
