The purpose of the study was from the perspective of young people that has completed a stay at HVB-home. The respondents are between 15-21 years both boys and girls. The basic questions were: How do the respondents look upon this HVB-homes service process? How do the respondents look upon this HVB-homes service contents? How do the respondents look upon this HVB-homes service regarding available information and how the staff is available? What positive and negative experience do they have from their stay at the HVB-home? We also wish to get a picture of what is important to change to improve the quality on this HVB-home. To receive answers to those questions we formed a questionnaire.
Restspänningar i arc-förångade (Ti(1-x)Al(x))N ytskikt
This report is the written documentation of a project work carried out at the Division of Engineering Materials at Luleå University of Technology in cooperation with Seco Tools AB. The project deals with the analysis of residual stresses in Ti-Al-N thin film grown on WC/Co cutting inserts. The composition of Al varied from 0% up to 75%. Increasing the Al content in the Ti(1-x)Alx N compound improves the compressive residual stresses even after annealing of the material. The experiments have been performed in a high temperature x-ray diffractometer (HTXRD) where the interplanar atomic spacing was determined in-situ and subsequent converted into stresses.

Vilka faktorer påverkar komposition och val av växter? : olika aktörers sätt att arbeta
The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.
Matematik i förskolan : En jämförelsestudie mellan en traditionell förskola och montessoriförskola
This work is about how teachers describe their work with mathematics in a traditional nursery school and a Montessori preschool. Another aim is to study how children mathematise on the two different preschools and to see if there are any differences between the various educational theories and practices mathematising. I have used two methods wich is interviews with preschool teachers, and observation of the children. The results of my study was that differences exist but the biggest difference is the material that Montessori uses. The difference between the teachers' way of teaching mathematics is to Montessori preschool places great emphasis on the material and how it is used, while in the traditional preschool puts the emphasis on learning through interaction with others.

COMPARATIVE STUDY OF HYDROLYSIS PERFORMED WITH MODERN MICROWAVE TECHNIQUE AND THE TRADITIONAL METHOD
Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
Litteraturrecensioner i Expressen och BLM 1964-2004 : En studie av genreförändringar i två skilda pressorgan
The aim of this study is to describe how reviews of literature in Bonniers litterära magasin and Expressen changed during the period 1964-2004. The investigation is based on 20 reviews of novels and short stories, which are analysed with a method described in Hellspong and Ledin (1997) and inspired by Halliday. The theoretical frame of the investigation is founded on critical discourse analysis (Fairclough 1992 & 2001) and Habermas´social theory of the public sphere.The investigation shows, among other things, that the reviews became shorter and easier to read in both paper during the period. The investigation also shows that the genre´s style, composition and contents are relatively stable, and that current ideologies in society have a tendency to be reflected in the reviewers´evaluation of the books. To generalize, the reviews thus developed from a poetic genre in 1964, to become political in the 1970s, academic in the 1980s, feminist in the 1990s and finally an intermedial genre in 2004..
Vad vet gymnasieelever om betygskriterierna och kursplanen i Idrott och Hälsa?
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
Kan det vara hypertext? Ett försök att analysera en månglineär, flersekventiell pappersburen text som hypertext
The object of this thesis is to discuss the limits of the hypertext concept. The issue is whether the concept of hypertext necessarily depends on the conditions of the electronic media and www, or if the concept of hypertext more likely is founded on certain textual structures and strategies. In the light of contributions to hypertext theory during the 1990s, this thesis compares different views on hypertext, and concludes with an evaluation. The poem it the authors own translation of the original Danish title det, written in 1969 by the system-poet Inger Christensen, is the object of this case study. The poem is analysed with respect to its structural organisation and literary composition.
Uppfödning av gyltor till hållbara suggor
Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.
Lagerkostnadsarbete i teori och praktik: En fallstudie av lagerkostnader på ett sågverksföretag
This thesis investigates how inventory management is practiced at a Swedish sawmill company, how practice differs from theory in this field and how the company could make more use of this theory. To do this we have performed a study on relevant literature and compared our findings with a field study on Moelven Valåsen AB. Our analysis shows that a large gap between theory and practice exists. We identify several reasons to this, including some sector specific problems when calculating cost rate for timber inventories. Suggestions on solutions to these problems and an example of how a cost rate can be estimated with relatively simple means are presented.
Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt
This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition.
These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.
Hur oberoende är de enskilda juverdelarna hos en mjölkko?
Mastit är en sjukdom som leder till stora problem i svenska mjölkkobesättningar. De flesta mastiter är subkliniska inflammationer som ofta inte upptäcks på grund av avsaknaden av synliga sjukdomssymtom, men där SCC är förhöjt och mjölkkvaliteten försämrad precis som vid klinisk mastit. Detta leder till att mjölk med förändrad sammansättning och kvalitet levereras till mejerierna som därmed har sämre förutsättningar att framställa mejeriprodukter av hög kvalitet. Även lantbrukaren drabbas ekonomiskt, dels på grund av att ett förhöjt celltal inte ger maximalt betalt för mjölken och dels på grund av en minskad mjölkmängd då all mjölk från kor med konstaterad subklinisk mastit ofta kasseras. Vid mjölkning i automatiska mjölkningssystem finns möjlighet att separera mjölken på fjärdedelsnivå redan vid mjölkning, detta sker dock inte idag.
Att effektivisera armeringsarbete : Från idé till genomförande
Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.
