    Analysis and modelling of single domain core-shell (αFeNi/chromite) nanoparticles emitted during selective laser melting, and their magnetic remanence

    Despite recent intense implementation of increasingly eco-friendly additive manufacturing, the properties of nanoparticulate pollutants emitted during Laser Powder Bed Fusion are still not fully understood, and have generally been overlooked. This study aims to fill this gap in current research by providing new insights into distinct metal/oxide core-shell nanoparticles (3–36 nm) that are produced during 3D printing using stainless steel. It also suggests possible ways for the removal of these potentially harmful by-products. Further, this research also provides a newly developed kinetic model that predicts a metal core growth time of below 200 μs and confirms the predicted theory for the formation of these by-products. In the current study it was found that the cores produced during this process are purely metallic and consist of meteoroid phase kamacite (αFeNi). Within this study there was found to be a complete dominance of single-domain cores of kamacite with prevailing particles below the superparamagnetic threshold showing strong magnetic response and remanence. This new knowledge can be used to minimize potential health risks and reduce contamination of raw materials by this nanoparticulate pollutant, which can adversely affect the quality of printed metal parts, the environment, and the health of the operator. These findings also provide a new possibility of targeted efficient production of superparamagnetic core-shell nanoparticles with a metallic kamacite core during laser powder bed fusion of austenitic steel 316L powder, which can be used in the production of sensors.Web of Science400art. no. 13668

    Nanostructures for Achieving Selective Properties of a Thermophotovoltaic Emitter

    This paper focuses on the research and development of a suitable method for creating a selective emitter for the visible and near-infrared region to be able to work optimally together with silicon photovoltaic cells in a thermophotovoltaic system. The aim was to develop a new method to create very fine structures beyond the conventional standard (nanostructures), which will increase the emissivity of the base material for it to match the needs of a selective emitter for the VIS and NIR region. Available methods were used to create the nanostructures, from which we eliminated all unsuitable methods; for the selected method, we established the optimal procedure and parameters for their creation. The development of the emitter nanostructures included the necessary substrate pretreatments, where great emphasis was placed on material purity and surface roughness. Tungsten was purposely chosen as the main material for the formation of the nanostructures; we verified the effect of the formed structure on the resulting emissivity. This work presents a new method for the formation of nanostructures, which are not commonly formed in such fineness; by this, it opens the way to new possibilities for achieving the desired selectivity of the thermophotovoltaic emitter

    I have compared genomic sequences of three variants of tick-borne encephalitis virus, strain Hypr. The variants used were Hypr5 {--} virus passaged five times in suckling mice brains, Hypr50/V {--} a variant highly passaged in vivo in Vienna, and Hypr50/CB {--} a variant highly passaged in vivo in České Budějovice. Both high-passage variants were passaged in suckling mouse brains as well. I was interested in changes in nucleotide sequence of genomes of high-passage variants Hypr50/V and Hypr50/CB compared with Hypr5 and also consequential changes in amino-acid sequences of viral proteins. I have found several identical changes in amino-acid sequences of E protein, NS3 and NS5 proteins in both high-passage variants and also a number of substitutions unique to one of the variants in proteins E, NS1, NS2A, NS2B, and NS3. A nucleotide substitution was found also in 5{\crq}UTR of the viral genome

    No full text
    The bachelor thesis is focused on an employee motivation in an organization and its using in an efficient leadership. The bachelor thesis is based on a studying literature which is related to the subject matter and on the structured interviews with the managers of the chosen organizations. The theoretical part determines the basic concepts as a management, a role and tasks of a manager in an organization and a types of employee management. An emphasis was given on the concepts which deals with a general motivation as a motives of people, motivation resources and its obstacles. In the end of the theoretical part are defined the motivational theories by important psychologists. The empirical part is focused on the structured interview with the managers of the chosen organizations. The questions are focused on the way of motivating employees and the practical use of motivation factors

    Race Riots in Great Britain at the End of the 1950s

    No full text
    This bachelor thesis analyzes the causes, course, and consequences of the race riots in Great Britain at the end of the 1950s. The text concentrates on the conditions of immigration to the British islands after the World War II, especially immigration from the British West Indies, citizens of which dominated the immigration of the so called New Commonwealth in the 1950s. Attention is focused on growing antipathy of the majority of society against Caribbean immigrants whose presence was linked to a range of problems, particularly in the area of housing. In this and other areas of life in Britain, the immigrants were encountering prejudice, discrimination, and physical attacks. Main emphasis is laid on the escalation of tensions during the summer 1958 and the course of the race riots in Nottingham and Notting Hill at the turn of August and September 1958 which shook the whole Britain. The final part of the bachelor thesis analyzes the reaction of British society to the race riots and their impact on the Caribbean community

    Determination of N-glycome of the tick \kur{Ixodes ricinus} and \kur{Dermacentor marginatus}; Analysis of N-glycans in tick tissues and their comparison

    Glycosylation in vertebrates has a main role in many important processes such as cell transport, protein folding, secretion of proteins etc. What function has glycosylation in arthropods, for example in ticks, is rarely studied. This work was focused on analysis of N-glycans in tick tissues, namely in Ixodes ricinus and Dermacentor marginatus. High-mannose glycans as well as complex glycans with or without core-fucosylation were identified in this study.Furthermore several sialylated glycans were present in the studied samples. Sialic acid is found in arthropods rarely and this is the first study which directly proves its presence in ticks using mass spectrometry
