Exekutive Funktionen (EF) sind eine Gruppe von Top-Down-Prozessen, die in neuartigen Situationen eingesetzt werden, um neue Trigger-Response-Assoziationen herzustellen oder vorhandene Handlungsoptionen an neue Situationen anzupassen. Obwohl EF erschöpfend untersucht wurden, bleiben wichtige Fragen offen. Beispiele dafür sind (a) Sind Exekutivfunktionen vollständig trennbar oder beruhen sie auf einem gemeinsamen neurokognitiven System? (b) Was messen verschiedene Versionen der Stroop-Aufgabe, einer der meist-verwendeten Aufgaben zur Prüfung der Inhibitionsfunktion? (c) Muss Inhibition immer Ressourcen-fordernd sein, oder gibt es eine Form der Inhibition, die mühelos implementiert werden kann? Zur Beantwortung dieser Fragen, habe ich neurokognitive Korrelate von EF und ihrer Verbesserung mithilfe posthypnotischer Suggestionen (PHS) und Ereigniskorrelierter Hirnpotentiale (EKP) untersucht. Zusammenfassend ergaben sich folgende Antworten: (a) Psychometrische und EKP-Daten aus den Studien zur Gedächtnisaktualisierung und Inhibition sowie deren Verbesserung anhand PHS zeigten sowohl funktionsspezifische als auch gemeinsame neurokognitive Prozesse der Inhibition und Aktualisierung. (b) Obwohl sowohl die vokale als auch die manuelle Version der Stroop-Aufgabe Inhibitionsfunktionen erfordern, ist die vokale Version Ressourcen-fordernder, da sie mindestens einen zusätzlichen Lokus der Interferenz im Antwort-Produktionsprozess aufweist, der nicht mit PHS beeinflussbar ist und der in der manuellen Version fehlt. (c) Unter Verwendung PHS zur Erhöhung der Präferenzen für kalorienarme Lebensmittel untersuchte ich die Auflösung von Konflikten. Die EKP-Ergebnisse zeigten, dass auch Konflikt-Auflösung, ähnlich wie Inhibition, Ressourcen konsumiert. Insgesamt zeigt dieses Projekt, dass die Verwendung Aufgaben-bezogener PHS in Kombination mit Neuroimaging-Techniken einen fruchtbaren Ansatz für die Untersuchung ungeklärter Fragen über Exekutivfunktionen darstellt. / Executive functions (EF) are a group of top-down processes used in novel situations to develop or adapt existing responses to the task at hand. Even though EFs are studied exhaustively, several important questions remain unanswered: (a) Are EFs entirely separated, or do they rely on a common system? (b) What do different versions of the Stroop task measure? (c) Does inhibition always need to be effortful? To address these questions, I investigated neurocognitive correlates of EFs and their enhancements by means of posthypnotic suggestions (PHS) and event-related potentials (ERP). However, before one can use PHSs, it must be elucidated whether and how they affect EFs. Although PHSs are used repeatedly for improving inhibition, it is unclear whether their effects are mediated by bottom-up or top-down processes. By using an updating task, I showed that effects of PHSs can be attributed to top-down processes. Accordingly, a new theory of hypnosis was proposed and empirically tested by modeling hypnotizability scores with structural equation modeling. In short, the simulation-adaption theory suggests that several top-down processes are employed for responding to suggestions. After elucidating the driving mechanism of PHSs is mentally practicing a novel strategy, PHSs were used for addressing the questions regarding EFs. Summarizing (a) the psychometric and ERP results from several studies indicated that different EFs rely on both function-specific and shared neurocognitive processes. (b) Even though different versions of the Stroop task are tapping into inhibition, the vocal compared to the manual version has at least an extra response-production-related locus of interference. (c) Using PHSs for increasing preferences for low-calorie food items, it is shown that resolve is effortful to implement, as indicated by increased P300 amplitudes. Together, this project shows how PHSs, along with neuroimaging techniques, can provide a novel approach for investigating EFs.

The main aim of this work is to carry out analysis of programmes of direct support for small and middle-sized companies offered by the state, European Union and commercial sphere, also description of process of acquision of support in chosen company and evaluation of the benefits in factual company. To support small and middle-sized companies is sensible and pragmatic because this segment is an importand part of the development of national economy, increases employment, cocreates healthy business environment and therefore develops each village, town and region. The support is related to efficient and stable companies only. The operational programmes help small and middle-sized companies to dynamize their growth and development, they are not dedicated to saving companies with problems.

This Master Thesis is the research done in the country of Rwanda. The project leads to study the climate of this country in order to establish whether this climate could be used to produce energy from air and to implement the first wind turbine for serving the nation.   After an introduction about the historical background of wind power, the thesis work deals with assessment of wind energy potential of Rwanda in focusing of the most suitable place for wind power plants. The best location with annual mean wind speed, the rate of use of turbine with hub height for an annual production per year, the mean wind speeds for 6 sites of Rwanda based on ECMWF for climatic data for one year at relief of altitude of 100m and coordinates are reported too.   The result of energy produced and calculations were done based on power hitting wind turbine generator in order to calculate Kinetic energy and power available at the best location to the measurement over the period of 12 months, that could be hoped for long term.   With help of logarithmic law, where wind speed usually increases with increasing in elevation and the desired wind speeds at all 6 sites were used. The annual energy production was taken into account at the best site with desired wind speed at the initial cost of turbine as well as the cost of energy (COE).However, with comparison of the tariff of EWSA, the price of Wind designed in this Research per kWh is cheaper and suitable for people of Rwanda. / <p><em>Rwanda has considerable opportunities development energy from hydro sources, methane gas, solar and peat deposits. Most of these energy sources have not been fully exploited, such as solar, wind and geothermal. As such wood is still being the major source of energy for 94 per cent of the population and imported petroleum products consume more than 40 per cent of foreign exchange. Energy is a key component of the Rwandan economy. It is thus recognized that the current inadequate and expensive energy supply constitutes a limiting factor to sustainable development. Rwanda’s Vision 2020 emphasizes the need for economic growth, private investment and economic transformation supported by a reliable and affordable energy supply as a key factor for the development process. To achieve this transformation, the country will need to increase energy production and diversify into alternative energy sources. Rwandan nations don’t have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural areas. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The application of renewable energy technology has the potential to alleviate many of the problems that face the people of Rwanda every day, especially if done so in a sustainable manner that prioritizes human rights.</em></p>
