Från färdighetsträning till vokalt uttryck : Om sången i grundskolans läroplaner
The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.
Värdering av kvävet i organiska gödselmedel :
Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers.
This project contributes to this knowledge by investigating whether relatively simple and
repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

KOM LOSS En studie av Läs- och skrivstugans verksamhet på tre bibliotek i Västra Götalandregionen
The purpose of this Master Thesis is to investigate whether the technical service available in the "Reading and Writing Corner" has an influence on the total quality of service in a public library. This service is intended to give sensory/print-handicapped persons access to information. The title KOM LOSS is a Swedish expression for "come on" and LOSS is short for reading and writing support. I have chosen to study three libraries in the region of Västra Götaland, Sweden. The thesis examines total quality from the aspects of goal steering, accessibility, education and marketing.
Kampen om tidningssidorna: landsort vs. storstad : En kvantitativ innehållsanalys av landsorts- och storstadsnyheter i två rikstäckande tidningar
The purpose of this essay is to examine and compare the news covering of Swedens three biggest cities (the metropolitan areas) and their surrounding areas with the covering of the rest of the country (the provincial areas) in two daily national newspapers, Aftonbladet and Dagens Nyheter. The aim has been to answer the following questions:- What amount of the news coverage in Aftonbladet and Dagens Nyheter concern the metropolitan areas compared to the provincial areas, and how do these two newspapers differ in the news covering of these areas?- Is there a difference in the news articles size and content, depending on weather they concern the metropolitan or the provincial areas?- How has the balance between news concerning metropolitan and provincial areas changed over the recent 20 years?The theories used in this study are News values, the media commercialization and Popular Journalism, and The Agenda Setting Theory. The method that has been used is a Quantitative Content Analysis.Despite the essays hypothesis, that the news coverage in the two newspapers would be dominated by material from the metropolitan areas, the result showed that a majority of the examined articles concern the provincial areas. It also showed that Aftonbladet has a bigger percentage of provincial news than Dagens Nyheter.
Uppföljning av krediter : förutsägelse av finansiell kris
Background: During the year 2002 approximately 27 000 people lost their jobs because of companies filing for bancruptcy. In 2002 the number of companies filing for bancruptcy in Sweden were 6740. This is approximately twice as many as in the year of 1974 when the first major study concerning bancruptcies in Sweden was carried out. The accumulated amount of unpaid bancruptcy claims for the period 1991 ? 1997 was 51 billion SEK.
Sociala medier : Marknadsföring och innehåll
The purpose of this study is to highlight the opportunities of using social media as a communicative tool to attract and engage customers on different social media platforms. In recent years social media has become an important way for business to communicate with people both national and global. The idea behind this thesis was found when we saw different approaches of how companies used social media as a marketing tool. Through a qualitative approach we did eight interviews with six different companies and two social media consults which have given us a basis of what companies really want to achieve with social media. With these interviews we were able to analyze and discuss the abilities to interact with people and how companies distribute content that engage users and increase their credibility to the company..
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

Bibliotek och intranät ? en fallstudie av intranätanvändandet i en biblioteksorganisation
This master?s thesis seeks to examine how a public library use the intranet with regards to the possibilities that today?s intranet technology offer ? especially concerning functionalities that support information, communication and knowledge exchange in the organization. The purpose of the study is to investigate how employees in one specific public library perceive and use the intranet in their daily work. The theoretical framework takes its point of departure in two complementing models regarding the implementation, development and management of intranets and a model of a multi perspective view of the intranet as a shared information space for content, communication and collaboration. The study is based on interviews with eleven of the intranet users, whom with the aid of an interview guide have been asked questions regarding goals, implementation, content, design, applications and advantages/disadvantages with the intranet.
I vilken utsträckning kan hästar enbart utfodras med grovfoder?
Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.
Livscykelanalys för koldioxidutsläpp från flerbostadshus
Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.
