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.
Stamräkning och identifiering av åtgärdsbehov i röjnings- och gallringbestånd med hjälp av låghöjdsbilder
This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
Fr?n kryph?l till skotth?l En motivanalys om undantag i svensk lagstiftning om vapenexport efter lag?ndringen 2018
This study aims to contribute to the existing research field of Swedish arms export by
examining the motives behind how the Swedish government and ISP have warranted arms
export to countries in or on the brink of armed conflict after the change in law in 2018. The
current Swedish legislation from 2018 with its basis in international legislation does not
allow arms export to countries in or on the brink of armed conflict, but it still occurs due to a
law that allows for exceptions if the arms export aligns with Sweden's interest in security
policy. Earlier research has been conducted in the field and stated that Sweden?s progressive
brand makes it possible for Sweden to export arms and still come across as a peaceful
country, and that the Swedish government is involved in the arms trade which is essentially a
private market. The analysis uses the theory of militarization to establish possible motives
and a theoretical framework.

Bilder från dödsbädden : En kontextualisering och funktionsstudie av två postuma barnporträtt
This essay, Pictures from a death-bed, expands on the pictorial genre called post mortem portraits, a field with long history in the western society. A post mortem portrait is an artwork where the artist paint or photograph the model after her or his dead. My survey delineates to treat two specific pictures, one from the seventeenth century and one from the twentieth century. Both of them are portraits of dead boys on their death-beds, but the first one is a painting and the other one is a photo. By this survey I wanted to find both similarities and differentials between the pictures; if they were made by the same reasons, if you could see anything different between the portraits by children and by the portraits of adults, and finally, if there were any cultural or religious connections between the pictures and their existents.

Title: Point of Purchase TV-screens - An analysis of Gender and Generations in the In-store-Retail-EnvironmentDate of Seminar: May 29th 2007 Course: BUS 809, Master Thesis in International Marketing and Brand Management.Authors: Søren Berg Jørgensen, Daniel McCartney and Ben Wallenborn.Supervisors: Karin Alm and Ulf Johansson Keywords: In-store Marketing, Point-of-Purchase, In-store TV, Gender, Generations. Thesis Purpose: The purpose of the thesis is to contribute to a greater understanding as to how consumers react to and perceive PoP TV-screens within the in-store retail environment. More specific, the aim of the study is to investigate if gender and generations react and feel differently towards the use of PoP TV-screens. From a practical standpoint, the study will aid marketers in how they can communicate more effectively with their target-market inside the store. In addition to this, the study will provide retailers with an insight into the overall atmospheric effect that the placement of TV screens has on stores.
Katalogen som tolkningsredskap : Bibliografiska relationer i Resource Description and Access (RDA), med särskild hänsyn till operationaliseringsproblem
The new cataloging code Resource Description and Access (RDA) provides a system of instructions for recording relationships between related resources by means of a controlled vocabulary of relationship designators. The purpose of this two years master?s thesis in Archive, Library and Museum studies is to examine the construction of this system, as well as its theoretical foundation. One theoretical point of departure is the necessity of operational definitions for consistent identification of bibliographic relationships. Another such point of departure is that the theoretical model on which RDA is based (the FRBR model) is not a complete description of the bibliographic universe, but merely a limited representation of a set of assumptions about that universe.The thesis first examines Barbara B.
Utvärderingsmodeller, Hur några av Göteborgs universitets- och högskolebibliotek har utvärderat sina IT-tjänster
The main subject with this master thesis is to take a closer look on how some of the university libraries of Gothenburg have evaluated their electronic services (such as search-systems, Internet-based services, CD-ROM etc.). The information technology has made its way into the library field during the past century and needs to be evaluated and quality measured to ensure the best possible service to the users. Since evaluation of electronic services is a new area in the evaluation field, some problems has arisen in terms of choosing evaluation strategies and finding the appropriate performance indicators for the evaluation process. The main questions asked in the thesis are; - Which are the most common theoretical strategies for evaluation? - How do some of the university libraries of Gothenburg perform evaluation in practice? - How does the various strategies for evaluation apply to the context of this thesis? The results show that specific strategies for evaluation aren't used in the reports discussed in this thesis.
Mata inte trollen : En studie i marknadskommunikation och internetkultur
Social media provides, as many points out, new possibilities for marketing. Marketing in social media requires a two way communication, rather than the traditional marketing where the communication model is typically sender ? receiver.To create a marketing campaign that is suitable for a two way communication model has its difficulties and risks as well as its opportunities. Opportunities in the sense that the campaign can become a viral, a Word of mouth and create a Buzz, which will reach potential customers, to a bigger quantity for lower costs, with a message that will make a different impact from the types of commercial messages we are used to. Risks in the sense that the message, if not properly aimed and phrased, can be turned overnight into something that humiliates the company and possibly harm its brand.The difficulties in creating such a campaign is to create something that will catch people?s attention, discuss and forward it, while at the same time avoid getting hurt.We aim to describe the internet from a cultural context, and from that point of view explore the types of misunderstandings which often seem to happen when a corporate message is created and sent out in social media, how to avoid putting the image of a company in danger when doing this, and examine if there is ways to know how the message will be received.
?Poor, fucked-up, kinky, philanthropic Christian Grey? : en studie i maskulinitet och fantasier om manlig sexualitet i romansviten Fifty Shades of Grey
The current paper is a study of the character Christian Grey in the EL James trilogy Fifty Shades of Grey. The main aim is to find out how masculinity, sexuality and gender are constructed in this erotic fantasy. More over terms as femininity, unmanliness and gender have relevance to the study. Several studies have been done on romance novels and Harlequin in particular from a gender perspective, but few of them from a masculine point of view. Hence, no earlier study has been done on Fifty Shades of Grey with masculinity studies as the main tool of masculinity, or with theories of romance.

Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Forskningsfronten inom informationsvetenskap ? en bibliometrisk analys
The aim of this study is to analyze and describe the research front within information science. To reach this purpose we ask the following research question: Which research themes can be identified within the subject field of information science by using bibliographic coupling in combination with cluster analysis.The data for our study consists of articles from the journals Journal of the American Society for Information Science and Technology and Journal of Documentation throughout the years 2004-2006. The bibliographic information from the articles was analyzed with the combined methods of bibliographic coupling and cluster analysis. This gave fifteen clusters within which we identified research themes. When analyzing these results we found four main fields of research within the research front of information science: Information retrieval, bibliometrics, knowledge organization and information science as research discipline.
Markberedningens, planteringspunktens och behållardjupets inflytande på granminiplantors etablering i fält :
A new type of forest tree seedling, called mini seedling, has been developed by the University
of Dalarna in Garpenberg, Sweden. Compared to traditional containerized seedlings
that are grown for 1 ? 2 years, mini seedlings are grown for only 10 weeks. The mini seedlings
are small, easily planted, cost effective, and reduce the amount of chemicals used in
the nursery. Research has shown that mini seedlings tend to have higher overall survival
rates than traditional container seedlings.
Prediktering av komponenters mognad/kvalitet utifrån felkodsutfall
This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.
