Förutsättningar för återintroduktion av stora gräsätare i Sverige

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

Prediktering av skogliga variabler med data från flygburen laser : En jämförelse mellan multipla regressionsmodeller och k nearest neighbour-modeller

This study has the purpose of looking at the current and future position of record labels from a context involving the technological developments, while the opportunities for the artists are changing. As the actors inside them music industry find themselves in an ever changing climate where traditional supply chains are threatened by new technology, the record labels need to change the way they work in order to maintain their existence in the music industry. The study has been conducted by interviewing a number of people involved in the music industry, by using a qualitative method approach. The conclusion of the study shows that the traditional way of doing business by treating music as a product that makes revenue is gone. Instead the labels have to take on new roles formerly run by third parties in order to survive and be profitable, especially since artists can now in control of activities that used to be controlled by the record label..

Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

Borde Sverige gå från ett spelmonol till ett licenssystem gällande EMV lotterier? : En kostnadsnyttoanalys

The gambling industry goes from a national matter towards an international market. Since more and more members of EU does liberalise the gambling reforms and introduces a license system more participants will get an EU license for online gambling. With an EU license it is difficult for members of the EU to refuse a company to offer a gambling supply on the Internet if they don?t have an open license system. This paper tries to acknowledge the problem regarding the monopoly Sweden has today and calculate the effect if Sweden would move to a license system regarding online gambling by doing a cost benefit analysis.

Hur Internet används i konsumentens köpprocess vid handel av kläder

A study based on the consumer buying decision process to discover the typical use of the Internet in the consumer buying decision process when buying clothes. The matter is researched through an Internet survey which discovers how the consumer use the Internet in each step of the buying decision process by using predetermined options. As a result, the conclusion is that people most commonly use the traditional alternatives in the buying decision process of clothes. However, information about a product is often collected on the Internet, mostly on different webshops. The main reason, for people to buy clothes on the Internet, is that the consumers consider it is more convenient and time saving.

Flödesoptimering i begränsande resurs

Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.

Avveckla eller utveckla mjölkproduktion : vilka faktorer påverkar beslutet?

The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased. In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.

Galgar ? något att hänga upp sig på. En studie av galgens roll i ett klädföretags värdekedja

Klädbranschen har fått stor uppmärksamhet gällande hållbarhet och miljökostnader. Tidigare forskning har främst täckt frågor kring hållbara material och transporter samt arbetsförhållanden för dem som producerar kläderna, medan andra aktiviteter som ingår i ett klädföretagets värdekedja inte har fått så stor uppmärksamhet, trots att de också har en stor påverkan på miljö och kostnader.Innevarande uppsats handlar om klädföretag och hur deras rutiner gällande upphängning av kläder på galgar fungerar. Syftet med arbetet har varit att undersöka var i värdekedjan kläderna galgas och hur returhanteringen av galgarna sker samt hållbarhetsperspektivet kring detta.Teorin har tagits fram från olika vetenskapliga artiklar, böcker samt hemsidor, och informationen som redan finns i ämnet och som är relevant för undersökningen presenteras. Teorin tar upp termen Supply Chain Management (SCM) och hur det ser ut i klädbranschen. En överblick av aktiviteter som ingår i ett klädföretags värdekedja ges, där "pre-retail"-aktiviteter och returflöden får stor uppmärksamhet.

Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

Avsikt, insikt och moraliskt ansvar : En genomgång av diskussionen gällande doktrinen om trippel effekt mellan Frances M. Kamm och John Harris.

This work is meant to contribute to the research of adaptation studies by focusing on a special case: the transformation of a fictional diary into a movie. In order to sustain the form of the literary source the adaptation to movie requires certain strategies. Först of all, the diary genre is characterized by a one-dimensional narration. Second, diaries only supply a few written dialogues, hence this "void" has to be compensated and filled by media specific measures. Third, the investigated diary is a story of individualization and emancipation of a single woman.
