Förbättring av den svenska kiselalgsmetoden-hantering av sedimentering
Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water.
The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water.
First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.
Säkerhetsbrytare för Gräsklippare
This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower.

A Comparison of Two Immunoturbidimetric Assay Methods for Serum Amyloid A in Cats.
The analysis of acute phase protein serum amyloid A (SAA) has recently been brought into clinical use in veterinary medicine. Some of the difficulties with incorporating the SAA method in clinical practice have been the expensive and rather large equipment required for the method. Due to these difficulties only larger clinics can afford to use the SAA analysis.The company Equinostic has recently developed a smaller instrument that costs one-tenth of a larger instrument. The instrument is named EVA1 and has so far only been used to analyze SAA in horses.The aim of this study was to investigate if the EVA1 instrument could be used to analyze SAA in cats. This study included 24 serum samples from cat, which were first analyzed twice on the EVA1 instrument and then sent to the Strömsholm Referral Animal Hospital in Sweden where they reanalyzed the samples using a validated reference method.
Stockar och stenar falla där, istället för tårar : en studie av häxprocesserna i Torsåker, Ångermanland 1674-1675
The purpose of this Bachelor thesis is to examine how user-friendly the OPAC of the Märsta public library is considered to be.Theoretical basis are HCI and Allwoods definition of usability. Issues are: Is the OPAC suited to its task? Is the OPAC user-friendly? How well does a user accept the OPAC? and What degree of competence is shown by users of the OPAC? The source material consists of six interviews in the form of .avi files. The method I have chosen is qualitative semi-structured interview form. The result is that, based on Carl Martin Allwood?s defini-tion and with exception for the using of help-resources, the usability of Märsta?s library OPAC can be considered less good..
Grazing behavior of Ankole and Boran cattle in an improved herding production system
To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.

Logistik i byggbranschen : Fo?r fo?rba?ttrad arbetsmiljo? och effektivitet
Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.
Barn i och kring kyrkobyggnaden fram till och med 1600-talet
The purpose of this essay was to find out if it is possible to:? Detect different groups of gender among children in grave materiel and church art and if that was the case, in what way?? What different groups of children can be seen in these two categories?? What does the material say about children's position in society? The time span is from early Christian time to 17-th century and the geographical region is Sweden and Denmark. I got my information from published literature and different pages on the Internet. The conclusions were that gender among children can be detected in both types of material but different groups were not ?visible? to the same degree.
Time and architectural representations: the illusion of being eternal
Att beskriva en byggnad som tidlös är bland det finaste en kan säga. Några av världens mest uppskattade byggnader har beskriv- its som just det, tidlösa. Hur kommer det sig att en av den finaste komplimangen och erkännandet en byggnad kan få, egentligen är intetsägande?
Tiden går ständigt och det finns ingenting någon kan göra för att ändra det. Människor, djur och även byggnader utvecklas och åldras.
Rydboholms engelska park : historik och vårdprogram
The estate of Rydboholm is situated in the municipality of Österåker, north of Stockholm, Sweden, and has a long history dating back to the 14th century. Rydboholm was the home of several families of great national importance, such as the Finsta and Vasa clans. However, since the 1500s, the noble family Brahe was the most influential; leaving its mark on the castle and surroundings. The gardens of Rydboholm consist of two parts; The first is from the baroque era, dating back to the 1660s, and the second is an immense landscape park completed around the year 1800 by Magnus Fredrik Brahe.
During his travels through Europe, Magnus Fredrik Brahe was influenced by the new English-style gardens and he brought a large collection of literature on the subject back to Sweden, still kept in the library of Rydboholm.

Therefore the task was todesign a smaller and lighter syringepump.The goal of the project was to create aprototype of the design that met themechanical requirements posed. Therequirements were met.In the report the work process can befollowed from the development of thespecifications to the final design andtests of the prototype.
Brunius, Zettervall och Graebe : ett jämförande studium av tre domkyrkorestaureringar
The purpose of this paper is to clarify and understand the difference between Brunius?, Zettervall's and Graebe's valueing of a historical building, the cathedral of Lund. Between 1833 and 1963 the cathedral of Lund went through three larger restorations. The character of the restorations however differs a lot between the three church architects, Brunius, Zettervall and Graebe. In a time of low interest for the Middle Ages and of many demolitions of churches in the countryside, Brunius stood out as a researcher and an enthusiast of that special time.
Det växer ju inte i magen men det växer i hjärtat : En kvalitativ studie om adoptivföräldrars erfarenheter av adoption
To investigate adoptions are part of the social worker's duties. The aim of our study was to examine some adoptive parents, to internationally adopted children, experience of adopting, the time before the adoption, the adoption process, and the time after the adoption. The study is based on qualitative interviews with seven adoptive parents. Theoretical frameworks that have been used are a phenomenological perspective, the dramaturgical perspective of Goffman and the theory of rites of passage.The result of our study shows that the adoptive parents have tried ?everything? to be-come parents in a biological way before they came to the decision to adopt.
Regioner i förändring - En komparativ studie av de svenska och danska strukturreformerna
The purpose of this thesis is to critically investigate how to understand the regional transformations that are occurring in Sweden and Denmark. At a higher level of abstraction the results can be generalised to a wider context and I have found that there is an ideological hegemony that explains the regional transformation. Nation states are reterritorialising due to a changing world where global capital is becoming increasingly flexible and competition between states, regions and municipalities is needed to adjust. By using Sandberg's model of structural reforms I have shown that the differences between Sweden's and Denmark's reterritorialisation are due to differences in national political culture and existing administrative systems. In fact these two structural reforms are based on the same regionalist ideology as a reaction to the changing global economy.To investigate the regional transformations I have carried out an idea and ideology analysis on the recent Swedish proposal from Ansvarskommittén, Strukturkommissionen in Denmark and the proposal by the Danish government which was carried out in 2007.
