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.

The purpose of this thesis is to shed light on the various factors that influence the balancebetween the working lives and family lives of social workers. The research questions posedwere: Do social workers consider there is a conflict between their working lives and familylives? Which factors make maintaining a balance between working life and family life moredifficult and which make it easier to do so? How do social workers describe equality betweenthe sexes in their own family? Regarding methodology, the selection method is strategic andcombines data sources with quantitative and qualitative methodologies. The material collectedand via online survey, targeted to 120 municipal employees social workers in a district councilin a big city, and through interviews with four social workers in a rural community. The studywas performed using gender theory and the demand-support-control model.

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.

The teachers would like the pupils to be more creative but don?tknow how achieve that at the same time as they have to teach them everythingthat they are supposed to know when the course ends..

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.

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.

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.

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.

The purpose of this study is to explore the factors affecting an individual's working life mobility and how this mobility is perceived by the individual. The study has a qualitative approach and the theoretical part is based on Castells', Giddens' and Bauman's theories of modern society and employment in relation to the individual. The study concludes that external circumstances in combination with internal driving forces are the reasons behind changing careers. The process is predominantly perceived as positive, especially education tends to strengthen self-identity. Work in general is regarded as important for a person's identity and new career changes are expected in the future..

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.

One of our reasons is that we think the subject usability is interesting, is that we think it is an important. Usability is maybe the most important element when you develop or choose a system because it can save money for the companies and give the users a more delightful and better work environment. The aim of the investigation is to find out if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. The objective of our investigation is to show if the implementation of a web portal is a direction to reach higher usability in a complex system that consists of several different interacting applications. In our case we will try to see if Karlshamns AB:s recently implemented web portal is more useful than their previous application (Movex with interacting programs) One thought with the report is to give the system developers a perspective of how the usability can be in-house made applications versus standard applications. Also companies that not have any computer- or department for development and which are thinking of get hold of, change, replace or complement their system and applications, may have some interest in our thesis. We have used a qualitative investigation method in our study to answer our hypothesis.

The purpose of this master's thesis is to examine and compare the process of starting a school library at schools which haven't had a school library before, and to examine and compare the experience of this process according to the principals and the persons responsible for the school library.I have examined two Swedish independent primary schools (age 6-15 years). I have made qualitative interviews with the principals and the persons responsible for the new school library. In all, I have made seven interviews. As requested by the new Swedish Educational Act, both schools had recently started creating school libraries. One of the schools had recruited a half-time teacher-librarian and the other had no staffing at all.In the interviews, I have examined the attitudes of the informants towards school libraries, if this attitude has changed during the process of starting the school library, the informants' experiences during this process and the informants' views on the school library as an agent for student achievement.

This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.

Abstract This essay is written to answer the questions of why, how and against who employees in the service sector use humour, charm and flirt in the interaction with their customers. The service management research is quite extensive, but despite this the research partly misses studies around why employees tend to act in certain ways while interacting with their customers. To understand the reasons of why they act in these particular ways, we need to know which factors that can be crucial when it comes to the employees? behaviour in these situations. By knowing the underlying reasons of using a special way to communicate with customers, it is much easier to achieve a clearer overview of the subject.
