I studien undersöktes effekten av bakgrundljud på prestationen i en räkneuppgift. Två experiment genomfördes för att testa effekten av tre bakgrundstal: irrelevanta tal, yrkesbeteckningar och tal uppspelade baklänges. Dessutom ingick en kontrollbetingelse utan bakgrundstal. Hypotesen var att de irrelevanta talen skulle störa prestationen mest. Experiment 1 visade ingen effekt av bakgrundsljuden och stödde alltså inte hypotesen.

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

The purpose of this project was to study how the interference between two antennas in a MIMO system affects the linearity of the power amplifiers powering the antennas. For the MIMO system, two power amplifiers and twoantennas were constructed and designed using the software ADS and a software defined radio was constructed using the platform USRP and the software LabVIEW. The result was that the interference between the antennas affectsthe linearity of the power amplifiers powering the antennas adversely and a reasonable theory was that the interaction decreases inversely proportional tothe square of the distance..

This study aims was to examine if working recreation instructors and the technical literature have the same or different outlook on when the grown ups should attend in children?s play, and what it is that separate them. The work method has been qualitative interviews. The number of interviewed recreation instructors is four. The study shows that the working recreation instructors that I have interviewed consider that it´s important to protect children´s freedom in there play without the grown up´s interference.

At ABB LV Motors in Västerås the shaft is assembled into the rotor with a shrink fit. After athorough investigation of the assembly method, several factors that make the insertion of theshaft more difficult has been discovered. Some affect the assembly directly while others onlyhave an indirect influence. The investigation has shown that the radial play between the shaftsouter radius and the rotors inner radius might be too small which could lead to anunsuccessful assembly. For the larger rotors, the condition is the opposite, and the rotor mightmove compared to the shaft direct after the assembly when the rotor still is warm.

This is an essay about the political development of Iraq after the overthrow of the Baath regime by the coalition forces in 2003. Almost seven years later, the political scene is still characterised by chaos, even though the country entered a new phase with the adoption of democratic thinking and a new openness to the world. The unstable political situation is a product of inter-ethnic conflict and the interference by neighbouring countries. Iraq is up against two formidable tasks ? building democracy and building a nation.

The aim of this study is to explain and analyse political steering of public libraries in Swedish municipalities and the roles of politicians and administrators in this process. To fulfil this purpose five municipalities have been studied. It is argued that both politicians and administration have to be included in a study of steering and that the relation between politicians and administrators should be seen as an interplay. Planning and evaluation are discerned as the two main activities in the steering process. The material in this study consists mainly of information collected through interviews with library responsible politicians and library managers in all five municipalities.The results show that libraries are considered politically uncontroversial and that politicians see little need for political interference and steering.

The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work.

This report deals with the modeling of a part of the communication system based on the IEEE 802.11a standard which represents the next generation of wireless LAN with greater scalability, better interference immunity and significantly higher speed, up to 54 Mbps. 802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) where modulation is performed by an IFFT and the demodulation by an FFT. After modeling the FFT in Matlab and C, the FFT implementation has been validated using a soft microprocessor core by Xilinx (Microblaze) and the results were compared..

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

The aim of this study is to examine the investment decision process for investments that arise due to strategic changes and are of strategic importance to the company. At the foundation of this study is the previous research in this area, done by King (1975) and Bower (1970), which examines the investment process on a more generic level. At the core is the investment decision process pertaining to Projekt X, an investment performed by NordiCorp. Having conducted a case study including six interviews with employees from various parts of the organization, combined with a large number of internal documents, the process regarding the investment decision was carefully illuminated. The results show that in many regards, this process follows the more generic investment process.

To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.

The Human Rights claim that all humans have special rights that are not allowed to be broken or violated. Although these rights are broken and violated by states every day. One major fact that makes this possible is the principle of sovereignty that includes all states, and which says that every state has the power and right to make decisions and create laws within the own country without the interference of other actors. In other words, the problem is that the states have to much power in relation to actors usch as the United Nations and to the rules of the Human Rights. This essay describe a possible way to strengthen the power of the Human Rights so that all humans can be guaranteed the fulfillment of the rights..

Since the beginning of the new millennium, China has opened itself to the outside world and in an enormous pace increased its contacts and relationships with other countries. The trigger to these dramatic changes of economic and foreign policies is the insight that China can no longer sustain its rapid economic growth, largely based on industrial production, on energy and raw materials from China alone.Good relations with African countries have been of highest priority in China?s strategy of ?Going global?. The new African policy is based on the two principles of mutual benefit and non-interference in internal affairs ? as opposite to the West?s strategy of structural adjustment programmes (SAP), which include massive interference in internal affairs.
