The thick shelled river mussel (Unio crassus) has a fragmented distribution in southern Sweden. It is a threatened and protected species. In both the Swedish red list and the IUCN Red List of Threatened Species Unio crassus is classified as Endangered (EN). Causes for this classification are for instance differentiated bottom substrate and deterioration in water quality. In this study, habitat preferences of Unio crassus were investigated to assist in future restoration work.

To complete an overweight treatment program is associated with better weight loss. Previous studies have in principle focused on drop-out from the entire program, not individual parts of a program. Factors previously shown to influence the patients´ weight loss results are: frequency of individual meetings with a professional, the lack of social support from family or friends, the lack of motivation and in a few studies vacations. In several studies the drop-out patients have stated that their reasons for drop-out were dissatisfaction with the staff and the program design. Drop-out has also been shown to be connected with difficulties in adherence to the diet.

Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.

I den här uppsatsen undersöker jag hur barns mående och beteende bedöms i samband med deltagande i stödgrupp på Trappan i Uppsala. Jag studerar SDQ-formulär (Strength and difficulties questions) ifyllda av barn och/eller deras föräldrar 2009- 2011. SDQ mäter sex variabler: a) emotionella problem, b) uppförandeproblem, c) hyperaktivitet/uppmärksamhetsproblem, d) kamratproblem, e) prosocialt beteende samt f) total svårighetspoäng. Materialet utgörs av skattningar för 166 barn. En ny rapport (Skerfving 2011) om utvärdering av stödgrupper i Uppsala län blir ett viktigt jämförelsematerial, men jag gör delvis andra metodiska val än rapporten.

The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.

Today there are many different Cad-applications on the market for engineers. Because of big building projects it has become more and more important to work with the same application or to have access to a neutral file type to be able to transfer files between different ones.This report studies the single objects and how they react when transferring them between ADT and ArchiCAD via the neutral type IFC. We have also been looking at problems during the transfer between and if there are some connections between these problems. Afterwards we created a neutral object model of a small country house to see if the objects appeared different. The result shows no differences.But looking at the problems that appeared during the transmissions they felt small and no logical.Today it is not possible to save in a neutral type without facing small problems.

The traditional view of maintenance is machine-based, where acute maintenance tasks are highly valued. Preventive maintenance is viewed as secondary and less desirable to work with. The more modern view is to regard maintenance as a process. The machine-driven tasks are still necessary but are viewed as a part of the big picture.The purpose of this study is to examine how to high light general difficulties concerning maintenance management to aid organizations to reflecting upon their own situation. The study is based upon a pilot study initiated by ProcessIT concerning relevant key figures in maintenance.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.

The Swedish curriculum says that the education will adapt and take notice of every child?s individual condition and needs. Every child has the right to development, to feel the happiness of growing and to experience satisfaction of making progress and overcome difficulties. In every class it is often children who need adapted physical education. The earlier these children can get support and practice, the bigger the chance is that they will catch up.

Laws, regulations and generally accepted accounting principles hold options on how companies should recognize revenue. Generally accepted accounting principles are determined by standard-setting bodies as the Accounting Standards Board and the Financial Supervisory Authority, which is influenced by international standard-setting bodies as the IASB. Service revenue is generally recognized when performance is completed, but there are variations in when a performance is considered complete. The different accounting options available create difficulties in comparing companies over time and between companies, which in turn creates difficulties to achieve a true and fair view. By clarifying what methods and principles in accounting for service income the unlisted companies in Sweden are using and why these differences exist, we have been able to study how the comparability and the true and fair view is affected by these differences.

The purpose with this study was to analyse students' conception of living things, and to establish how a social constructivist learning situation affect their conceptions. The method consisted of questionnaires, followed by group discussions and a final survey. The main result was that students have everyday conceptions about scientific phenomena that are reinforced by the social interaction. Some students were positively influenced by the interaction with their peers, where non-scientific conceptions were replaced by conceptions of a scientific nature. Furthermore, the cultural artifacts are of very good means, but the study showed a strong need for a knowledgeable person, e.g.a teacher, to guide students in the right direction during the discussions.

Studien syftar till att beskriva hur lärare i matematik upplever att de praktiskt hanterar elevers olika förutsättningar i sin matematikundervisning. Undersökningen genomfördes som en fallstudie av två lärare i matematik i grundskolans senare år. Det empiriska materialet består av fyra klassrumsobservationer, som analyserades för att identifiera olika typer av individualisering, samt fyra intervjuer, för att belysa lärarnas upplevelser av och tankar kring individualisering. Det framkom att det förekommer flera olika typer av individualisering. En del individualisering var ett resultat av lärarens medvetna val, men det förekom även individualisering som lärarna delvis var omedvetna om..
