Topografins inverkan på markvattenhalten i ett jordbruksdominerat avrinningsområde
Topography is an important parameter for catchment hydrology, since it is a driver for water flow. Moreover, topography serves as a basis for hydrological models, e.g. ?Top-model?, which is based on a topographical wetness index (TWI). Few studies of TWI have been conducted on agricultural catchment scale.
Four fields were studied in a Swedish drained agricultural catchment in order to evaluate the influence of topography on soil wetness.

The thinning Quotient - a relevant description of thinning?
Det finns en rad satt att beskriva gallringsformen. Ofta används begreppet gallringskvot i dessa sammanhang utan
att närmare ange vilken metod eller definition som använts for att beräkna den. Detta kan lätt leda till att
missuppfattningar uppstår. Denna studie belyser olika definitioners känslighet for bland annat beståndsstruktur,
gallringsform och stickvägsavstånd. Studien innehåller dessutom en jämforelse mellan olika metoder att mäta och
uppskatta gallringskvoten i ett bestånd.
Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark
This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.
Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält
Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.
Vårdprogram för utemiljön vid Zorngården
The purpose of this essay was to develop a conservation program for the outdoor environment at the Zorn House (Zorngården) in Mora, Dalarna, situated in the upper central part of Sweden. In the conservation program the Zorn House garden?s origins and development process has been studied by historical studies of various kinds. As a result a status report also has been made and a description of the garden's values. This has resulted in an objective discussion that provides guidelines for how the garden can be developed in the future.
En komparativ studie av matematikböcker i grundskolan 1842-2006
This paper is a study of some of the mathematics textbooks that were used in Swedish public schools from 1842 to the present. During this period several revisions of the curriculum took place and led to a change of contents in the various books. The first part is a description of the books chosen and highlights from each are given and compared with the corresponding curriculum. Also social and political change and the role of men and women can be studied in the examples presented. A comparison between similar topics and how they were accounted for in the older versus the newer books follows suite.
Bokbussens värde och funktion. En kvalitativ intervjuundersökning med bokbussanvändare och bibliotekspersonal
The purpose of this master thesis is to investigate if the mobile library has a similar role as the public library. To study this further we intend to examine the value and function of the mobile library. Answers are sought to the following questions: Can the mobile library be seen as a public library in a smaller scale? How do the users experience the value and function of the mobile library? What does the library staff think of the value and function of the mobile library for the users? What would the consequences be if the service of the mobile libraries would not exist? The method used was qualitative interviews. The groups of respondents are mobile library users and library staff.
?Man vill ju inte slå på stora trumman? : -en kvalitativ intervjustudie om svenska klädföretags CSR-kommunikation
Abstract The purpose of this study is to identify how Swedish clothing companies strategically communicate CSR ? the issue being that CSR communication is frequently scrutinized and criticized. This is examined using semi-structured interviews with six company representatives. The result is presented thematically, dealing with (1) conditions for CSR and CSR communication, (2) how to manage the issue with criticism and (3) which communication strategies companies use. Following conclusions are drawn: the companies can be divided into Mirvis and Googins phases integrated or engaged/innovative, with conditions characterizing these phases.

Marknadsinriktad miljökommunikation på Internet : försäkringsbolaget Folksam
Many companies are presently investing in different types of environmental strategies, and it is varying to what level they channel their resources to environmental efforts. It is also diverging to what extent organizations effort to profile themselves as environmentally conscious. This can be due to difficulties in reaching out to customers and to finding the most efficient method of green marketing communication.
The aim of this study is to analyse how an insurance company more actively can communicate environmental matters foremost in their contact with customers. One can in different mediums daily follow debates and discussions concerning the environment. Many insurance companies have also identified their role in performing green work.
Påverkar fysisk aktivitet det psykiska välbefinnandet, med inriktning fysisk självuppfattning och självkänsla, hos äldre?
Studier som berör ämnet hur fysisk aktivitet påverkar det psykiska välbefinnandet hos äldre är något som berör alla. Fysisk aktivitet har i tidigare forskning visat sig påverka båda den fysiska och psykiska hälsan positivt. Mycket forskning är gjord på området, dock är de äldre underrepresenterade som målgrupp inom området. Syftet med denna studie var att undersöka i vilken utsträckning fysisk aktivitet påverkar det psykiska välbefinnandet, med inriktning självkänsla och fysisk självuppfattning, hos äldre. Undersökningen innefattade en experimentell undersökningsmetod med en randominiserad, kontrollerad design.
Religionsfriheten i Sverige 1809 ? 1951 : Från samvetsfri kristen tro till fritt val av religiös tillhörighet i svensk lagstiftning
In 1809 the citizens of Sweden where given the freedom to practice their Christian faith through the Swedish constitution of 1809, 16 §. This proclaimed that there should be religious freedom in Sweden, albeit restricted to Evangelical-Lutheran faith. Although after the law regarding dissenters was passed in 1860 by choosing another church than the Evangelical-Lutheran church you lost some civic rights, for example you could not become a public official. The freedom to choose religious affiliation was given through the Law of Religious Freedom in 1951. The purpose of this study is to evaluate in what way the concept of religious freedom has developed in Swedish law between 1809 and 1951.In the background I treat two historical events and one era, with focus upon religious freedom, which have in my opinion influenced the view of religious freedom in Sweden during the chosen period of 1809?1951.
Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .
Förskolebarns motoriska utveckling : -Hur en förskolegård bör utformas för bästa tänkbara utveckling av barns motorik
The purpose of this study was to interview different groups of people (preschool teatcher, parents and theire childen) involved in preschool about their view on outdoor activity and children´s motoric development, and how a preschool yard should be designed to promote childrens development.All parties regard outdoor activity as very important for the development of children. They also think that the outdoor environment today is good but that it could be improved by including some trees and hills. The yard should also contain soil, sand, clay and water. The children prefer grass on the ground over other substrates. This study also gives good indications to decision makers how to build new or to reconstruct pre-school yards in the future..
