Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
Synchronous Latency Insensitive Design in FPGA
A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.

Accelererat åldrande av produkter Apelsinjuice och hallondryck
Brämhults Juice AB is one of Sweden?s leading producers of fresh fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.
Barn- och ungdomshockey utifrån ett tränarperspektiv : En kvalitativ studie om tränarnas uppfattningar om barn- och ungdomshockey
Abstract________________________________________________________________Författare/Author Richard TähtinenTitel/Title Youth hockey from a coach perspective. A qualitative study about coaches´appreciations concerning youth hockeyThe aim with this study is to strengthen the knowledge about coaches´ appreciationsconcerning youth hockey. This study contains interviews with three leaders that operate onthe strategic level within youth hockey and three coaches working with youth players in theages of 11 and 12. I have divided my main results into 4 categories, based on an earlier studyfrom Karin Redelius (2002). These categories include the following themes:1) Competition on the good and the bad2) The importance of winning3) Shake-out versus sports on children’s terms4) Instruction, play and learningThe main conclusions in this study show that leaders on the strategic level appreciate youthhockey in a very similar way.
Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.

Algebra i gymnasieskolan : Vilka svårigheter har eleverna?
During my practice as a teacher trainee at an upper secondary school it became clear to me that many pupils have difficulties with algebra. Also in a report from the National Agency for Education (1999) you can see that the students algebra knowledge get worse and worse. I was surprised to find that many pupils seemed to get stuck on the level of attainment for the senior level of the nine-year compulsory school. As I have not studied anything about difficulties in algebra during my training to become a qualified teacher I would like to get to know more about this. I also examine why you have to study algebra in upper secondary school.
Konstruktion av anordning för att undersöka förslitning av syrebärarpartiklar för kemcyklisk förbränning
The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
Vad påverkar och karaktäriserar positiva personer
People with positive affect seem to have great advantages in life. Goal achievement, the main cause of well-being for all organisms, seem to be a typical trait of these people. The purpose of this study was to examine (i) what influences positive affect, (ii) the relation between positive affect and goal achievement, and (iii) characteristics of individuals with positive and negative affect. Five individuals with self-rated positive affect and two with negative were interviewed. The responses were classified in fifteen themes.
"Jag brukar jämföra källor med varandra." : En studie i gymnasieelevers kritiska tänkande
The main purpose of this bachelor thesis is to examine the existence of criteria and to what extent high school students use these criteria when they are collecting information for a school assignment. I also compare students attending different high school programmes with each other and compare students on different levels of education.I have done a quantitative study with 284 students in which the students have filled out questionnaires.The result shows that the most common way to evaluate information is to compare sources with each other. Students also look at how the information is written, and they want the information to be detailed and easily available. More seldom used criteria include consideration of the authority of the writer, determination of how up to date the information is, and gauging the perspective of the information.The result also shows that students attending a high school programme that prepares them for higher education are better at evaluating information than students attending a high school programme of vocational preparation. Students at a higher level of education are also better at evaluating information than students at a lower level of education. .
Fysisk aktivitet = psykisk stabilitet? : En undersökning om relationen mellan mängden fysisk aktivitet och självupplevd hälsa
AimThe purpose of this study was to investigate the relationship between self-perceived health and level of physical activity among the staff at The Swedish School of Sport and Health Sciences (GIH). We focused on the following questions:How does the amount of physical activity affect the self-perceived health among the staff at GIH? Are there any gender differences in self-perceived health following the amount of physical activity? Do the self-perceived health and the amount of physical activity differ between the various age groups? Are there any differences between the staff responsible for health education compared with the other staff?MethodWe chose a validated questionnaire for our study. It was a combination of two already previously validated questionnaires together with our own supplementary background questions. The questionnaire was presented to 96 respondents and we received 76 answers.
Anknytningsmönster, copingstilar och stress inom relationsintensiva yrken : En kvantitativ studie rörande sambanden mellan anknytningsmönster, copingstilar och arbetsrelaterad stress
There has been a dramatic increase in long-term sick leave in Sweden, which largely depends on occupational stress. Occupational stress applies particularly in relationship-intensive jobs, which means that the individual works with a lot of contact or responsibility for other people. Research has shown that attachment is relevant to the choice of coping style and perception of stress in the workplace. The aim of the present study was to investigate the relationships between attachment patterns, coping styles and occupational stress in relationship-intensive jobs and to extend previous studies by adding the variables age, work experience and education in relation to coping styles and occupational stress. The study was in quantitative form in which 186 participants from various relationship-intensive jobs across Sweden participated.
