As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

For the company to work well, it is necessary with a good economy, a high qualitative production and a well working system concerning the environment: the whole cycle on the farm needs to be working. At the same time, debaters about the environmental impacts are also requiring higher demands for the dairy farmers and therefore also the management programs. Management programs for feed evaluation calculations have been more developed over the years. Big amounts have been invested in the new feeding system with NorFor, but no one seems to have asked the dairy farmers what they themselves want to spend their money on, and what they need help with. For the dairy farmers it is necessary that the whole company is controlled in the right way, and much more than just feed evaluation is included in this.

AbstractTitle: The first thing I do when I wake up is to log on to Facebook. A study regarding how users of Social Networks experiences the User Generated production. (Det första jag gör när jag vaknar är att logga in på Facebook. En studie om hur användare av de sociala nätverken upplever den användargenererande produktionen.)Number of pages: 37 (39 including enclosures) Author: Per MagnussonTutor: Christian ChristensenCourse: Media and Communication Studies CPeriod: Fall semester 2010University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The ambition with this essay is to examine how the online users of social networks experience the development of the Internet towards Web 2.0, and the enormous User Generated Content emerging from it. How do we receive User Generated Content from other people, and particularly what do we think about our own production.Material/Method: In order to obtain a deeper understanding of the attitudes and perceptions amongst people regarding this subject I used qualitative interviews with 9 people.

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Att införa lean principer inom sjukvården är ett relativt nytt område. Landstinget i Gävleborg och Gävle sjukhus är intresserade av att korta ner sina vårdköer med hjälp av logistiska metoder och lean production principer. Detta på grund av att vårdköerna på bland annat urologmottagningen på Gävle sjukhus bara växer. Lean production är ett koncept som ursprungligen härstammar från bilindustrin i Japan och innebär att man strävar efter att göra mer med mindre. På svenska kan lean production översättas till resurssnål produktion och arbetet med lean innefattar principer som kunden i fokus, teamarbete och ständiga förbättringar.Syftet med examensarbetet är att ta fram en arbetsmodell för införande av lean principer inom sjukvården, då vårdköerna idag är långa och någon form av förändring är nödvändig.

A large cost at the construction sites today is the labour cost of the workers. But unfortunately the worker potential is not used to full. It is not unusual to take into a count with a work-­?place-­?additional-­?time of 50% in some cases. By increasing the workers' motivation and responsibility for their tasks may reduce the time considerably, which also increases the potential for greater gains in construction projects.By using the situational leadership may the workers level of maturity develop entirely.

This study has been carried out at Södra´s 31 local forestry districts and within six plant terminals. The production and sale of seedlings at Södra is managed in collaboration with ?Södra Odlarna?. Approximately 35 million plants are cultivated each year, providing Södra´s members with a wide choice of high quality plants. The seedlings are nurtured at nurseries before transferred to plant terminals where they are stored and watered.

Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Femsjö is a small parish situated in Hylte municipality, Växjö diocese. The parish has a total area of 8230 ha of which 5000 ha are covered with forest. There have not been any large industries in the parish offering work opportunities for the inhabitants, so they have had to generate income from their land and the forest. Instead of going to the bank to get a bank loan the people of Femsjö parish went out in to the forest and harvested trees for timber and extra cash revenue. Production of pine tar and potash were two other ways that the residents of Femsjö parish could earn extra money for the household in order to keep starvation away.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.
