Utformning och installation av musikstudio samt audiosystem för inspelning och redigering

The education program System design at the University of Kalmar has since it?s beginning been missing a near by studio for it?s students studying towards audio and music. In the choice of examination project I would take upon this task, which was long wanted for the teachers and students at the university?s Musikhuset.Musikhuset became the buyer of the project, and the studio was to be installed at their premises. Unfortunately, the project got jammed by the university?s financial savings calculations, and was due to this delayed in the end for 11 weeks.

En förstudie för bioetanol produktion i Borås

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

Personlighetsskillnader mellan gymnasielärare och blivande gymnasielärare : Differences in personality between high school teachers and future high school teachers

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Fett - rekommendationer, kostvanor och konsumtion mellan 1935 och 2009

This literature research is meant to answer the following questions: ? What was the Swedes consumption of fat from 1935 to 2009? ? How has the fat consumption corresponded to the current recommendations? ? What is LCHF and which are the main advantages and disadvantages? Fat supplies us with energy, isolates and protect organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides.

Utsikt för olja : Hur värderas oljeaktier

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

Samspel i staden : en studie av Shared Space ur landskapsarkitektens perspektiv

In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.

Energieffektivisering av uppvärmningssystem i småbostadshus

Uppvärmningen av ett småbostadshus står vanligen för kring hälften av dess energianvändning. Enligt energimyndigheten drar det svenska standardhuset 22,7 MWh per år varav 12,2 MWh går till uppvärmning. Att ge värmesystemet så bra förutsättningar som möjligt bör alltså vara av intresse för varje husägare, kanske främst ur ett ekonomiskt perspektiv men även ur ett ekologiskt perspektiv.I detta arbete har olika energieffektiviseringsåtgärder studerats som kan implementeras i en tvåplansvillas värmesystem bestående av en värmepump, golvvärme på nedervåningen och olika värmedistributionssystem på övervåningen. Åtgärderna har innefattat både praktiska såsom val av isolering i golvvärmesammanhang och mer teoretiska såsom reglerstrategier. Relevant teori för de ingående systemen har presenterats och utgjort grunden för implementeringar av systemen i simuleringsprogrammet IDA Indoor Climate and Energy.

Nystartande av nötköttsproduktion med och utan bidrag :

Many dairy farms doesn?t keep their bull calves and cross cow calves, they sell them to breeders instead of raising them their self. It should be possible for the dairy farmers to do it them self?s. There is also a possibility to bread one calf from the cross heifers. The purpose of the investigation was to see if there is any economic possibility to breed beef cattle. I have used the same sample farm trough the hole study, because it would be easier to fallow the study.

Smörjningsfri led till industrirobot

IRB 340, Flexpicker is an industrial robot used for sorting, packaging and the handling of details up to two kg. The Flexpicker is a delta robot, meaning that it with three arms controls a triangular plate, swivel, in a work area shaped like a cylinder. Joints using plain bearings connect the arms.The plain bearing in use today consists of a plastic ring which slides against a hard anodized joint ball. Despite the fact that the plastic contain friction-lowering additives, the bearing needs to be lubricated to prevent noise. Because the robot is used in food and drug handling environments, where the demands on hygiene are set very high, the robot is often washed.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.

Energideklarationer i flerbostadshus i Gävle

Syfte: Syftet med uppsatsen är att undersöka hur energideklarationen har tagits emot och påverkat fastighetsägares arbete med energifrågor i flerbostadshus i Gävle.Metod: Denna uppsats baseras på kvalitativa intervjuer med fastighetsägare i Gävle. Fastighetsägarna som har medverkat är från den kommunala och privata hyressektorn samt kooperativa bostadsrättsorganisationer och privata bostadsrättsföreningar. Intervjumaterialet har sammanställts i fem olika kategorier i löpande text med förtydligande tabeller och diagram.Resultat och slutsats: Endast tre av de sju tillfrågade fastighetsägarna är helt färdiga med energideklarationerna. Alla respondenter anser att energideklarationen är bra över lag, men det finns även flera saker som de anser är negativt med energideklarationen. Majoriteten av respondenterna anser att de inte har gjort några större förändringar i och med den nya lagen, de jobbade redan med energibesparande åtgärder innan energideklarationerna genomfördes.Förslag till fortsatt forskning: I uppsatsen har vi inte tagit hänsyn till de boende och deras påverkan av energiförbrukningen.

Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Samband mellan hull, underhudsfett, levande vikt och fruktsamhet hos SRB och SLB :

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.
