Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawdust and cutter shavings although Sweden is rich in peat-findings. The aim of this work was to summarize the presented knowledge about the used of peat litter, techniques, advantages and disadvantages and to compare with other commonly used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat industries, interviews with peat producers and with peat researchers contributed to the material. Peat is not a uniformly material.

Syftet med studien är att undersöka makroekonomiska variablers effekt på Dow Jones och OMXS30, med hjälp av en lämplig ekonometrisk modell. Vidare är syftet att analysera möjligheten för börsprognostisering och analysera om denna möjlighet är lika stor för Dow Jones som för OMXS30. Detta kommer att ske genom att undersöka motsvarande variabler för respektive lands aktieindex. Variablerna arbetslöshet, ränta och oljepris visade sig inte ha någon signifikant påverkan på varken Dow Jones eller OMXS30. Det visade sig dock att aktieindexen reagerade på samma sätt, för respektive lands variabler..

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

The main purpose of this Masters thesis is to examine gender division in public libraries by reviewing literature and interviewing eight public librarians and two chief librarians. The reason why we decided to investigate this topic is the lack of research concerning sex-segregation in library and information science. By choosing this subject we intend to deepen the understanding of the significance of gender both within the public library and of the occupation in general. Some researchers claim that the low status of librarianship is a result of the large proportion of women in the profession. We want to find out how our informants view the relation between professional status and female domination.

Denna undersökning handlar om elevers kunskaper och uppfattningar angående höstlöven och nedbrytning i naturen. Studien har gjorts på två skolor i årskurs 3. Skola A har profilen ?Natur och Miljö? och skola B är en större skola utan profil. Syftet med arbetet är dels att kartlägga elevers föreställningar om nedbrytning i naturen och dels att undersöka hur man kan arbeta med ämnet i skolan för att få en god lärandemiljö.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

This one-year master's thesis investigates the late part of the Middle Neolithic on the island of Gotland. This thesis has been written without the influence of a singular theoretical pespective, and has therefore seen input from the processual, and postprocessual theories. By using several perspectives, an attempt is made to view the material remains used in the most objective manner possible. The specific aim of this thesis is to investigate whether the Mid-Neolithic inhabitants of Gotland were a part of the Corded Ware culture (or as it is called in Sweden, the Battleaxe culture or the Boataxe culture). Most recent literature has concluded that Gotland was never a part of the Battlexe culture, though this thesis has discovered many parallels with the mainland culture, including the production of similar objects and ritual practices.

This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.

The aim of this master?s thesis is to study the discourses on culture as developed by EU Commission. The method applied is a discoursebased historical analysis, where analysis of arguments and metaphors are functional to the enlightening of the construction of discourses within EU cultural policy. EU official documents constitute the empirical material studied. The theoretical framework of the thesis draws upon cultural public sphere theory as well instrumentalist cultural policy research.

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

In this paper, generic reference in a collection of juridical texts is examined, with focus on third person singular pronouns. The object of the study is to find out which generic pronouns occur in the material along with their relative distribution, but also to display further use patterns and to offer plausible explanations for these patterns. Another object is to evaluate whether the use of generic pronouns corresponds with language planners? recommendations for non-sexist language. The corpus studied consists of Rikspolisstyrelsens författnings­samling (?Statute Book of the Swedish National Police Board?), comprising 172 documents written between 1974 and 2009.The study is divided into two parts.

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.
