The objective of the present study was to evaluate distillers? dried grains with solubles (DDGS) as a protein source to rainbow trout (Oncorhynchus mykiss), by studying digestibility and growth measurements. One control diet, totally lacking DDGS, and three test diets were made containing 10 % (low), 31% (medium) and 51 % (high) DDGS respectively on dry matter (DM) basis. The control diet and the test diets were made to be as nutritionally equal as possible. Wheat bran was used to balance the fiber content of the diets.

The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning. Open questionnaires and half structured interviews were used to investigate this. Persons who answered the questionnaires and participated in the interviews were senior high school teachers in biology or science and high school science students. All the teachers and most of the students thought that field trips in ecology resulted in increased learning.

This is a study on how a group of ten pupils choose their upper secondary schools (gymnasium). All pupils are ninth graders in a middle school in Husby which is a suburb of Stockholm. Like the big majority of Husby citizens, they all have immigrant backgrounds and their time in Sweden varies; some are born here while others are born abroad and migrated later with their parents. My aim was to understand their upper secondary school choices through own and their parents? "cultural capital".

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

The aim of this study was to describe how adolescents experiences their quality of life, and tocompare if there are any differences in how they experiences their QOL depending on wherethey live, big town or smaller town. The aim was also to examine how adolescentsexperienced their schooling. The study is empirically, quantitative with a descriptive andcomparative design. To measure quality of life a tried and tested instrument ? LifeSatisfaction Questionnaire (LSQ) was used.

Background: When a person suddenly pass away, the relatives often arrive to the Emergency Department under chaotic circumstances. In this critical situation the nurse has an important role for the care. Many nurses lack of knowledge about how to take care of the bereaved relatives. Aim: The aim of the literature study was to describe aspects of caring for suddenly bereaved relatives. Method: The data for the study were scientific articles found in the databases PubMed and Cinahl and from a manual search.

Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

The purpose of this essay was to examine six high school welfare officers' experiences and work with students suffering from social phobia and discuss the welfare officers' view on social phobia from a psychiatric, cognitive and a knowledge theory. The study consists of qualitative interviews with welfare officers from several different high schools and attempts to answer the following questions: What previous experiences do welfare officers have of students with social phobia? How do welfare officers become aware of students with symptoms of social phobia and bring forth their problems? How do welfare officers describe their social work with students suffering from social phobia?The welfare officers' experiences of students with social phobia varied but turned out to be less salient than the amount of research in the area would suggest. The theoretical knowledge also varied, as did the acquiring and use of theory. These findings were then analysed on the basis of Rosmari Eliassons thoughts on knowledge, leading to the conclusion that the interviewed welfare officers do not construct their work on praxis-knowledge.

Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility. The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

Striga hermonthica, a parasitic weed, has long been believed to be correlated with the declining soil fertility status. However scientists have recently come to question this statement since some recent studies have shown contradictive results. To investigate whether soil fertility status and infestation of Striga hermonthica were correlated and the impact of it were caused by farmer management, 120 farmers in Western Kenya, where Striga hermonthica infestation is prone, participated in this study. In three districts with two sub-locations each, farmers answered a structural questionnaire and identified two fields, one with high and one with low soil fertility. These fields later came to be the basis for this study and soil were therefore also sampled from them.

Mothers and fathers in Sweden receive an earnings-related benefit of 80 percent of their income when they take parental leave. There exists a ceiling in the allowance though, meaning that some people with high earnings don?t receive fully 80 percent of their ordinary salary. The length of the parental leave varies between women and men and also among men and women. Various reasons are used to explain this; one of them is economical.

The purpose of the study was to describe hemodialysis patients self-reporting salt habits associated with cooking and food intake. Furthermore, the purpose was to investigate possible differences in inter Dialyze significant weight gain at low and high self-reported salt consumption. The study was an empirical descriptive study of comparative features and consisted of a convenience sample from two hemodialysis units in southern Norrland. Study group consisted of 37 persons who had been ongoing hemodialysis treatment and their age ranged from 42-86 years. A questionnaire was used in two parts and both parts contained 15 foods.
