Articles published in the Journal of Family Psychology over a 23-year period (1990-2012) were analyzed for their attention to ethnic groups in the United States. Articles were analyzed in terms of their ethnic population of interest, topic of study, funding sources, sample characteristics, and use of measures. Findings indicated that the journal has showed an increased focus on and sensitivity to issues relevant to ethnic groups in the U.S. However, there are several gaps in research for some groups, especially for Native American populations. Recommendations are offered to family science researchers, psychologists and other mental health professionals and educators.

I detta självständiga arbete studerar jag hur min kreativa process i komposition påverkas och förändras av olika faktorer. Studien utgår från ett fenomenologiskt perspektiv och tar inspiration från tidigare forskning och litteratur inom ämnena komposition och kreativitet. Arbetet har genomförts genom att använda loggboksanteckningar som tagits före och efter varje kompositionspass under höstterminen 2020. Anteckningarna har därefter analyserats med en tematisk analysmetod. Resultatet presenteras i två teman: yttre faktorer och inre faktorer, med tillhörande underrubriker som beskriver de olika faktorernas påverkan i större utsträckning. I dessa två teman beskrivs svaren på mina forskningsfrågor: Vad uppfattar jag som kreativitet? Vilken inverkan har olika metoder och rutiner på mitt kreativa skapande? Arbetet avslutas med en diskussion där resultaten ställs i relation till vald forskning, litteratur och det fenomenologiska perspektivet. / In this self-study I explore how my creative process in composition is affected and changed by different factors. The study is based on a phenomenological perspective and takes inspiration from previous studies and literature within the subjects of composing and creativity. The study has been accomplished using log notes which were taken before and after every composing session during the autumn semester of 2020. The log notes were analysed using a thematic analysing method. The results are presented in two themes: external factors and internal factors, with associated subheadings that describe each of the different factors’ influence in a bigger picture. In these two themes the answers are described to my two research questions: What do I perceive as creativity? What influence do different methods and routines have on my creative making? The work is finished with a discussion where the results are set in a relation to the selected research, literature, and the phenomenological perspective.

This master’s thesis is aimed on design of polymer coating machine that sprays polymer sliding coatings onto surfaces of crankshaft journal bearings used in car engines. At the beginning of this master’s thesis, basic overview of crankshaft bearings design and materials that are used for sliding coatings is given. Then suitable manufacturing technologies for different materials of coatings are described. After describing basic principles of coating technologies and how crankshaft bearings work, main components used for design of the spraying machine are introduced. Three prototypes of the machine are created in virtual environment to verify ergonomics of control and to fulfill safety requirements. In main part of the thesis, description of all parts and subassemblies, such as frame, spraying circuit, pneumatic regulators and safety features is given. Also functions of all parts of the machine are explained in details. Moreover system for handling and manipulation with coated bearings during all necessary technological operations was created. In addition functionality of the machine was verified and checked by spraying of polymer coating on testing samples and crankshaft bearings.

The diploma thesis contains a research part focused on turbocharger construction, engine lubrication system and turbocharger, basic physical properties of lubricating oils and hydrodynamics. The purpose of this thesis is to create analytical and CFD computational model of turbocharger lubrication system. Output pressures and the loss of specific energy are determined.

This work deals with experimental analysis of fluid film instability in rotor bearing systems stored in hydrodynamic plain bearings with focus on bearing surface modification. The experiments were performed on a journal bearing dynamics simulator. The aim was to determine the influence of individual operating parameters on the occurrence and course of turbulence instability. The emphasis here was on the effect of surface micro textures. The work also included the preparation of textured samples. Experiments were divided into experiments monitoring the influence of temperature, pressure, bearing geometry and surface modification. The output of the individual experiments were the values of the threshold speed of formation and termination of instability or the magnitude of the amplitude depending on the above described parameters. These values were plotted in graphs. This data was then confronted with previously published articles. The results showed that instabilityin rotor systems is very sensitive to temperature, pressure and bearing geometry changes. The fundamental influence on the unstable behavior of the rotor system has been demonstrated by the use of textured surfaces, where the threshold speed was significantly shifted to a higher speed range compared to the non-textured bearing.

The first part of the thesis describes journal bearings characteristics, their function and lubrication. The second part of the thesis is about a rotor-dynamics issue and how to use numerical and experimental methods for verification of a new bearing design. The practical part of the thesis is focused on analyse a current design of bearings in MBS. In the last part has been made and verified a new bearing design.

Die Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden hat eines der publizistischen Flaggschiffe der sächsischen Landesgeschichte in das Internet gestellt: das Neue Archiv für sächsische Geschichte. Die ersten Reaktionen sind positiv bis begeistert, kann doch jetzt jeder Interessierte, ob Mitglied eines Vereins oder Studierender, so schnell und so leicht wie nie zuvor auf alle Artikel der Zeitschrift zugreifen, ohne Umstände und ohne Gebühren.

Zeitschriften gehören zu den teuersten, aber auch am häufigsten genutzten Medien in Bibliotheken, die allerdings allein von 1975 bis 1995 eine Preissteigerung von 300% erlebten. Innerhalb weniger Jahre ist, vor allem in den naturwissenschaftlich-technischen Fächern, jedoch der Anteil von elektronisch angebotenen Zeitschriften stark gestiegen. Die Verlage bieten heute meist die Kombination von elektronischen und gedruckten Zeitschriften an. Die Universitätsbibliothek Leipzig hat sich für den größtmöglichen Umstieg auf elektronische Zeitschriften entschieden und die Printexemplare abbestellt, um Binde- und Platzkosten zu sparen.
