This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Sten Jonsson wants to start a production of an advertising catalogue for small companies in Sweden. Acatalogue where the advertisingcost is so low that most of the companies can afford to participate. Thecompanies who will advertise should be manufacturing companies in trades of carpentry, sheet metalworkshops, forging workshops and engineering workshops.The catalogue will facilitate for the manufacturer to reach the costumer without any middleman.Without a middleman creates a possibility for an opinion about the product at the same time as theprice can be held low. A catalogue of this type would benefit the marketing of the companies at the sametime as it would generate an occasion for innovations.The possible target groups are property companies, construct companies and farmers.A market research has been carried out contained a postal interview and a phone interview. Themarket research carried out to get an understanding in what the companies think about the idea butalso to see if the companies are in interest of advertise in the catalogue.

For a company to get the best possible profitability, requires financial planning. Budgeting isa common tool in financial planning.

Our conclusionregarding when it?s suitable to use which method is entirely dependent on thespecific project.

The Swedish building stock accounts for nearly 40 percent of the total energyconsumption in the country. Properties built today are likely to last for 100 years orlonger. This places high demands on long-term and smart energy solutions that willkeep the future Swedish building stock energy consumption at low levels. This thesishas focused on examining how the energy performance of buildings is affected bydifferent choices of window types in different cardinal directions. The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.

The purpose of this study has been to examine whether the bottom fauna of the stream Stensjöån, has been negatively influenced since the harvesting of peat began on the nearby peat moss Skäftesmyr or not. Comparison has been made with the results of index calculations from earlier examinations in the stream, two calculated indexes has been made, Danish fauna index and ASPT-index. The sampling was made with the kick sampling method, SS-EN 27 828. Three locations were chosen for the examination, one upstream from the peat moss, one just downstream from where the brook from the peat moss joins Stensjöån and a third location near the outlet of the stream to the lake Stensjön. The samples were sorted and the found animals identified to the taxonomic level required for the calculation of the two indexes.

Tasmania is a state in Australia, and is also the country?s largest island. It is separated from the main land by a 429 kilometer wide strait. Every year, a large amount of people, cars and goods are transported to the island using a government owned ferry line, which generates approximately 300 million Australian dollars to the state?s economy ,every year. This bachelor thesis investigates the possibility of reducing the fuel consumption for the ferry traffic to and from Tasmania, which would also reduce the overall cost.

Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.

The sea-level is rising due to climate change. This report inquires into the possibleconsequences of sea-level rise in Värmdö and its archipelago with particular focus on roadsand buildings. Four scenarios with a sea-level rise of 0.5, 1.5, 2.5 meter and a worst casescenario of 3.9 meter are analyzed using a geographic information system (GIS) calledarcMap. The report also examines how Värmdö is taking into account future sea-level rise intheir planning today. The report´s findings show that uplift and sea-level rise cancel eachother out in the scenario with a sea-level rise of 0.5 meter, but that a number of more or lessimportant roads and buildings will be affected by a rise of 1.5 meters.

This study has the purpose of looking at the current and future position of recordlabels from a context involving the technological developments, while theopportunities for the artists are changing. As the actors inside them music industryfind themselves in an ever changing climate where traditional supply chains arethreatened by new technology, the record labels need to change the way they workin order to maintain their existence in the music industry. The study has beenconducted by interviewing a number of people involved in the music industry, byusing a qualitative method approach. The conclusion of the study shows that thetraditional way of doing business by treating music as a product that makes revenueis gone. Instead the labels have to take on new roles formerly run by third parties inorder to survive and be profitable, especially since artists can now in control ofactivities that used to be controlled by the record label..

The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.
