One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

May 2010 a project called drop-in sports was started to get boys and girlsin the ages of 13-20 more physically active and keep them away from  committing crime. With the slogan ?come as you are, whenever you want and do what you want for free ? spontaneous sports was organized. To evaluate the project a research of the activity was carried out, where two of the objectives were to investigate how responsibility and empowerment is taken. Twelve hours of observations studies were used to collect data about leadership decision-making and democratic values in forms of respect, everybody?s right to play and influence.

This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.

The purpose of this investigation is to see if there is any difference in how long pupils are staying in the activity of the music- and culture schools in the country. I have compared this with how large the teachers engagements are in average at each school, how many teachers each school holds and if one teacher is teaching within different areas, e.g. on different instruments. Thru mail contact with the headmasters at the music- and culture schools I have gathered data concerning the length of which the pupils are staying at the schools, the number of teachers at each school, the size of the teachers services and in how many different areas each teacher is teaching.It has been hard to get to any results in the investigation since the music- and culture schools don?t compile statistics on how long their pupils are staying at their schools.

This report's aim is that by field measurements determine the function of Aprobo soundproofing material dB2 for reducing impact sounds, the measurements is done in ?the school for fine art? in Umeå also known as ?konstnärligt campus building nine?. The construction technique is used in areas sensitive to impact sound between different floors in the building. The measurement?s is also to do a function control of the buildings sound quality compared to Swedish and European standard when it comes to air sound, impact sound and reverberation time .

The aim of this study is to describe and analyse the creation and the design of a new public library. In order to concretize this, the study sets out from two examples, the public libraries in Simrishamn and Landskrona. The material used to attain the purpose of the study consists partly of interviews, partly of literature on the subject. To be able to put these two libraries in their historical context, the essay also provides a short overview of the development of public library buildings in Sweden during the 20th century. Another aspect that is discussed is the actual procedure of planning a public library from scratch.

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

An emerging trend within the construction industry is the expectation of the customer to experience and sense the product, maybe even in a customized manner. The latter trend would extend the necessity of incorporating not only function and aesthetics, but also perception and sensation. To meet this trend while at the same time improve the productivity the use of information technology such as BIM and technical platforms has increased in construction projects. Nevertheless, in spite of large investments, the construction industry has not managed to increase the effectiveness and productivity as much as other industries. Evident is that successful use of information technology depend on the integration and collaboration of various experts in a continuous and dynamic process.

Syftet med denna D-uppsats i finansiering är att undersöka om det finns något signifikant samband mellan Dow Jones Index och de oberoende makrovariablerna: kortränta, långränta, penningmängd, inflation, inflationsförväntningar och inköpschefsindex. Om samband påvisas avser jag att undersöka vilken och hur stor påverkan de olika variablerna har på Dow Jones Index. Mina signifikanta makrovariabler kommer jag sedan att tillsätta i en multiindex modell, vars syfte är att vara en beräkning av avkastning utifrån markandsrisken av en investering på New York börsen. För att undersöka sambandet mellan Dow Jones Index och förklaringsvariablerna användes multipel regressionsanalys. Undersökningen baseras på månadsdata från januari 1989 till och med oktober 2005.

The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition. The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet. Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management. More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

The aim of this study is to describe successful strategies to include children in free play activities at the preschool. The methods that pedagogues use to act and work with excluded children will be examined. To get answers to my questions I have conducted interviews with five pedagogues in four preschools. During interviews they mention two different approaches to encourage free play activity. One way was to participate and play along with the children.
