Ett vanligt förfarande i parapsykologiska s.k. ganzfeldexperiment är attmed hjälp av vitt brus, som spelas upp i hörlurar, försöka omslutaförsökspersoner i ett slags totalt och oföränderligt perceptuellttillstånd. I föreliggande studie undersöks konsekvenserna av attanvända vitt brus som bakgrundsljud. 30 försökspersoner har lyssnattill åtta ljudslingor innehållandes fyra typer av brus vid två olikaljudnivåer, för att sedan i ett enkätformulär uppskatta hur dessa ljudpåverkat dem. Resultatet visar på signifikanta effekter av så välbrustyp som amplitud, och dessutom en signifikant interaktionseffektdem emellan.

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

I did my degree project together with Universeum AB. The project had the work title: children?s world and the aim were to give children between 3-8 years old a place that was especially made for them. With their interests and needs in mind the area should trigger play but also learning through a well planned pedagogical environment.I did this project because I thought this was an excellent opportunity to really practise my new gained skills I had learned during my two years in CCD (Child Culture Design). It also gave me the opportunity to actually see how well my knowledge was working when it was put to the test, and I did learn a lot from this.Together with a crew of 6 people I developed and designed the area.

Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

The purpose of this study was to investigate and describe the views on how the mediation program Programa Árbol Sicómoro affected inmates?, convicted of murder, own lives. Research questions:? To what extent, and how, has the mediation affected the convicts? views upon themselves and the crime they have been convicted for.? To what extent, and how, has the mediation brought any change to the convicts? imprisonment and if it has changed their look upon the future.The study has been executed using qualitative method. Materials from seven profound interviews have been analysed and condensed using terms from restorative justice and self-image theories.

Bakgrund: Abort är en händelse som berör många. Orsaker till avbrytande av havandeskap kan variera. Kvinnors känslor och upplevelser efter inducerad abort är viktigt för sjukvårdspersonal att ha kunskap om.Syfte: Syftet var att belysa kvinnors känslor och upplevelser efter att ha genomgått inducerad abort.Metod: Studien genomfördes som en systematisk litteraturstudie där vetenskapliga artiklar söktes genom databaser på Internet och genom manuell sökning. Nio studier användes i litteraturstudien. Artiklarna analyserades och resultatet sammanställdes utifrån Travelbee´s begrepp Lidande och Mening.Resultat: Resultatet strukturerades i underrubrikerna Mental ohälsa, Trauma, Sorg, Tankar, Hälsa, Lättnad och Självförtroende.

Purpose: To examine how a tour operator works to implement sustainability in the development of the business, as well as what significance it has to consumers in selecting a tour operator. Furthermore, the purpose is to provide recommendations on how tour operators should work to communicate their commitments.Methodology: The research strategy applied is a case study which follows an abductive approach. Qualitative and quantitative methods were applied to complement each other. A semi-structured interview with a tour operator and a consumer survey constitute the empirical foundation.Conclusion: The conclusion of the study is that consumers show a positive attitude towards CSR, but do not see it as a determinant when choosing a tour operator. Thus, CSR does not constitute a competitive advantage against competitors.

Någon gång i livet kommer de flesta individer tvingas möta på de svårigheter som en sorg för med sig. Sorg är en reaktion på en förlust. Syftet med studien var att belysa stödformer som kan hjälpa individer i deras sorgeprocess. Där sorgeprocessen i detta fall relaterar till förlusten av en närstående. Deltagarna var 23 stycken kvinnor mellan åldrarna 19-62 som hade upplevt en sorgeprocess till följd av närståendes bortgång.

Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.

Syftet med denna uppsats är att studera huruvida prognoser är ett kompletterande eller konkurrerande verktyg till budgeten på tillverkningsföretag samt hur valet av styrverktyg kan ha påverkats av företagens interna och externa förutsättningar som dess organisationsstruktur, produktion och omvärld. Företagen vi har studerat visar på att prognosen inte är en konkurrent, utan ett komplement till budgeten. Alla de studerade fallföretagen använder sig idag av de båda styrmedlen. Flera företag säger sig ha andra styrmedel än budget, men det har visat sig att dessa styrmedel skiljer sig inte mycket från den traditionella budgeten. Budgeten har blivit en institution och har rotats fast i organisationer och gör det därför mycket svårt för företag att bryta sig loss ifrån den..

In this essay I analyse the constructions of gender in the series The Phantom by Lee Falk. I apply David Tjeders readings of the bourgouise masculinity, its sensitive character and great risk of falling into unmanliness, when discussing The Phantom?s masculine development. I have analysed three adventures of The Phantom from the years 1937, 1977 and 1996, all authored by original creator Lee Falk. I argue that The Phantom increases his use of violence, therefore risking a loss of character.

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.
