Introduction of emission trading scheme of tradable permits become a great phenomena among energy business agents. Each emitter of CO2 is granted or allocated definite amount of tradable permitts. These allow him to produce one tonne of CO2 or to sell them on the spot or forvard market. Since these tradable permits became valuable (behave as a commercial instrument) they carry two possible usage. To be consumed when producing MWh of energy of to be sold on the market. These alternative usage are according to economy theory opportunity costs, therefore should be considered as the implicit costs and implemented into the price setting. When operating on competitive market, this cost increase should be fully passed on to the price. In this paper we analyze this pass-through of the permits costs. By using regression analysis we try to estimate the pass-through rate of the permits costs in power energy market. We analyze the spot and futures market in the Czech Republic (PXE) and in Germany (EEX). Estimated pass through rate ranges between 0,65 and 1,2. The results emphasize that the energy market is quite competitive, because the costs are more or less fully passed on consumers. One interesting feature arose from results. The pass-through rate greater than one is sort of economically counter-intuitive and should be studied in more detail in some future work.

Omega 3 poly unsaturated fatty acids (n-3 PUFA) have been shown to protect against sudden cardiac death following myocardial infarction and reduce the risk of ventricular arrhythmias in patients with heart failure. At the inception of this study, there was one clinical study that reported n-3 PUFA supplementation reduced the risk of atrial fibrillation (AF) following CABG. As AF is a very common arrhythmia and as there are no safe and effective means of preventing AF, we designed this study to further validate the findings of the previous study in a more robust study design. In addition, this study also aimed to evaluate the cellular changes that underpin the beneficial anti-arrhythmic effect of n-3 PUFA.The outcome of this study shows that n-3 PUFA does not reduce the risk of AF following CABG. However, short term supplementation with n-3 PUFA reliably increases the membrane incorporation in phospholipids and results in alteration in the expression levels of cardiac calcium handling proteins phospholamban and ryanodine receptors. In addition, such incorporation in animal (rat) ventricular myocytes leads to changes in the rate of decay of the systolic calcium transient and an increase in the amplitude of the caffeine induced calcium transient thereby indicating a greater activity of SERCA. These findings needs further evaluation but is clearly interesting as the clinical situations where n-3 PUFA have been shown to be anti-arrhythmic are situations where cellular calcium overload is the main mechanism of arrhythmogenesis.

Numerical simulations of a 15° restraining bend analog claybox experiment include considering the fault geometry, rheology, and boundary conditions. The numerical models show that a growing fault from an analog experiment propagates at depth rather than at the surface and is exposed in later stages of the experiment, and that the wet kaolin clay from the analog experiment is partially decoupled from the steel plate. The numerical models provide the stresses to predict accurate fault growth from the analog experiment and provide the evolution of external work within the fault system. The external work from the numerical models decrease as faults continue to grow, which agrees with the continuously increasing kinematic efficiency within the analog experiment. Three-dimensional mechanical models are used to simulate the southern San Andreas fault. These models show that incorporating fault interaction, time since last earthquake rupture, and nearby earthquakes affects the stress state along a fault. Absolute shear tractions are calculated by multiplying time since last earthquake rupture with the simulated interseismic stressing rates for each fault strand. From our multi-cycle model, fault interaction affects local normal stressing rates so that the stresses are not relieved in between earthquakes. We provide our absolute shear tractions and scale our multi-cycle normal stressing rates to be near to failure so that dynamic rupture modelers from University of California, Riverside use our results to simulate earthquake propagation for the complex fault region of the San Gorgonio Pass.

This diploma thesis is focused on methods of using cement kiln by-pass dust in building materials technology. By-pass dust was treated to remove chlorides and could then be used as other constituent to various types of cements in the amount of 0–5 wt. % according to ČSN EN 197-1. The properties of dusts before and after chloride removal were examined and after incorporating modified by-pass dust into the cement, the properties of fresh and hardened cement pastes and mortars were studied. It was found that modified by-pass dust after incorporation into cement fulfill requirements of ČSN EN 197-1.

This thesis deals with the analysis of coaxial cavity filters and synthesis of generic topology of these filters. Transfer function comes out the synthesis, which is based on low-pass prototype and similarity with real structure. The next aim of this thesis is to build the basic software for coaxial cavity filters synthesis from engaged characteristic parameters of the filter. This work also includes the analysis of coupling matrix synthesis based on transfer function, where we can use direct coupling or cross-coupling between resonators. The last point is focused on the diplexer filter based on specified parameters and obtained coupling matrix. Entire diplexer model is optimized using Tuning-Space Mapping method.

Moving to a pass/fail curriculum has generally been associated with decreased levels of stress and increased medical student well-being. However, not much research has been done to identify the specific effect of retaining class rank in a pass/fail curriculum and how this might affect student stress levels. The purpose of the current study was to fill in current research gaps in this area and to provide further insight into some of the factors that contribute to medical student burnout. The study was carried out using the Medical Student Well-Being Index (MSWBI), a self-reported survey that evaluates medical student fatigue, depression, burnout, anxiety/stress, and mental/physical QOL on a weighted and unweighted basis. Additionally, a set of add-on questions developed by the research team were distributed to participants along with the MSWBI. These questions asked the students to determine whether the change to a pass/fail curriculum increased, decreased, or did not change their perceived stress levels and to identify the major sources of their perceived stress. Participants were full-time medical students enrolled at ETSU Quillen College of Medicine from the Fall 2019 to Spring 2020 terms. They were divided by graduation year and asked to complete the MSWBI and IRB-approved add-on questions once per school year during this period. The number of add-on question respondents from each class reporting an increased or unchanged level of stress since switching to a pass-fail system encompassed 62.6% of all respondents. The most common reason provided by respondents for either increased or unchanged levels of stress after switching to a pass/fail curriculum was the continued reporting of class rank. This work will be useful in determining the true sources of student stress within the medical education system. While a pass/fail curriculum may reduce medical students’ perceived stress, this data indicates that class rank remains burdensome for many. Understanding the underlying factors that influence poor medical student well-being can lead to better targeted interventions.

In den Grundlagenfächern der Ingenieurwissenschaften sind immer noch recht hohe Abbruchquoten zu beobachten, die oft mit Überforderung und mangelnder Motivation der Studierenden im Übergang zwischen schulischem und hochschulischem Lernen zu erklären sind. Um den Lernenden einen eher eigenverantwortlichen und damit intrinsisch motivierenderen Ansatz zu bieten, werden in der Hochschuldidaktik aktivierende Methoden verwendet. Im Falle großer Gruppen bieten sich hier insbesondere gamifizierende Elemente an, die ohne größere Umbrüche in der Konzeption von Veranstaltungen eingesetzt werden können und spielerische Herausforderungen in den Lernansatz einführen. In der vorliegenden Untersuchung wurden strukturell gamifizierende Interventionen in ein Informatikmodul eingeführt und nach Durchführung der Veranstaltungen die Bestehensquoten und studentischen Evaluationen hinsichtlich des Kompetenzerwerbs der Studierenden miteinander verglichen. Erste Ergebnisse der noch laufenden Untersuchung weisen darauf hin, dass die eingesetzten Elemente die Quoten und Evaluationen positiv beeinflussen. Lassen sich die Ergebnisse auch über weitere Vergleichsgruppen bestätigen, sollten die Treiber dieser Veränderungen genau untersucht werden, damit die Anwendung dieser Methoden auch für den Einsatz in anderen Grundlagenfächern oder Hochschulen generalisiert empfohlen werden kann - um damit letztlich zu verminderten Abbruchquoten in den Ingenieurwissenschaften beizutragen.

This study investigates if a smartphones orientation in the pocket affects the result of a decision tree model trained with data from personal falls, and also how a low-pass filter affects these results. A comparison is made between the results gathered from this study, compared to previous studies and products within the field. The data was gathered using a smartphone application and was later split up to get datasets for all the different orientations of the smartphone. Before training the models, the data was processed through a low pass filter. Results showed that low pass filtered signals generally performed better and that two of the trained models, could outscore at least one other algorithm cited in this thesis in at least one category. However, existing products on the market that were investigated do not disclose their statistics and a comparison to these products could not be made. The best two orientations for the phone to be placed in the pocket was when the face of the phone was pointing out from the leg, and top of the phone was pointing up and also when the face of the phone was pointing out from the leg, and the top of the phone was pointing down.
