Bulleremissioner från vertikalaxlade vindkraftverk
Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

TV broadcast sport always attracts a great number of viewers, also in Sweden. The prices of broadcasting rights to sporting events have risen strongly during the last decade, much as a consequence of the increasing competition between different TV companies both internationally and in Sweden.
Positionering under operation : en enkätstudie om anestesisjuksköterskans rutiner
Syftet med studien var att beskriva anestesisjuksköterskors kunskaper och rutiner för positionering och mobilisering under operationer med en anestesitid över 3 timmar. Studien genomfördes som en kvantitativ enkätundersökning, med en kvalitativ aspekt. Data insamlades genom en enkät som lämnades ut till samtliga anestesisjuksköterskor på ett länssjukhus och ett länsdelssjukhus i Mellansverige. Resultatet visade att ca hälften av respondenterna önskar sig mer kunskap om vikten av positionering för att kunna förebygga skador. Anestesisjuksköterskor som ansåg sig ha tillräckliga kunskaper om positionering undersöker oftare patientens hudstatus inför en längre operation.

Därefter studerades svenska doktriner och reglementen avseende teorier om grundläggande förmågor och hur verkan uppnås i striden.
Internationell närvaro- nationell frånvaro? En jämförande studie om återuppbyggnaden i Afghanistan och Kosovo med fokus på civil-militär samverkan
In this thesis the aim is to explore the connection between International presence and Reconstruction of Postconflict states. The focus in this Analyse is the concept of CIMIC which is the institutional concept of Civil-Military Co-operation in International relations and a concept in Peacebuilding Theory. The cases, which are the empirical Material, is Afghanistan and Kosovo, two most-different cases.The theoretical framework is primarily consider the mechanisms successful for the Reconstruction process in general and within CIMIC in particular. This framework including both theories of State failure and International administered Territories as well as Models for Civil- Military Co-operation.The International presence in Postconflict Societies plays a big role, even thou it is very important that initiatives for rebuilding comes from the state within. The essence of CIMIC is the civil component and the military, operating in Peacebuilding and Reconstruction missions.
Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :
Background
Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses.
The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.
Sjukdomsfrekvens och utslagningsorsaker hos kor med 12 respektive 15 månaders kalvningsintervall
The incidence of many of the most common diseases in dairy cattle has been proven to be highest during the time closest to calving. It is possible that the current breeding strategy with 12 month calving intervals increases the risk for disease in dairy cattle, which is problematic concerning both animal welfare and for economic reasons. The economic incentives behind a calving interval of 12 to 13 months have mainly been based on milk- and feed- costs and no costs due to diseases or fertility disturbances have been included.The aim of this study was to see if a lengthening of the calving interval would result in lower disease frequency. The hypothesis is that cows with a planned calving interval of 15 months have a lower disease incidence than cows with a calving interval of 12 months due to less number of calvings. Therefore the difference in disease frequency should be larger when compared over a long period of time, such as over lifetime, since cows with a longer calving interval experience fewer calvings.The study was performed between August 17th, 1994, and January 24th, 2007.
Är Grönt Skönt?: En studie om hur effekten av grön marknadsföring påverkas av förekomsten av miljöargument inom produktkategorin
Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.
Pust och stånk! Meen vad roligt vi hade när vi fick igång det. : En diskurspsykologisk studie av personals samtal om barns delaktighet i dokumentationsprocessen på förskolan.
There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
Språkinlärning och Språkutveckling : I en förberedelseklass i högstadiet
Then the language learning process and the approach in a preparatory class differs itself from a general class. The methods conducted in a preparatory class are not just focused on teaching as in a more traditional method. Achieving the objectives in a preparatory class depends on the individual student and the cohesion in the group. Students have different backgrounds and knowledge level, therefore it is extremely important that the teachers use different work methods in order to achieve and to promote the students' language development. The aim with this survey is to get the knowledge about what education methods is being used by teachers in a preparatory class.
