The effect of arginine on root system development in Norway spruce (Picea abies L. Karst) somatic embryos

The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.

Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.

Diversitet hos jordlöpare (Col: Carabidae) i hävdade strandnära gräsmarker :

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

Magnesiumstatus hos mjölkkor : en fältstudie

Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. Due to the fact that potassium fertilisation leads to a higher potassium content in forage, it is of interest to study interactions of potassium on the magnesium balance in dairy cows. There are few studies about magnesium feeding to dairy cows in Sweden and the purpose of this study was to investigate how much magnesium and from which feed-sources dairy cows in Sweden get their magnesium. Data was collected from seven farms in the northern part of Uppland and from seven farms in Skaraborg in Sweden.

Medling i dispositiva tvistemål : En kritisk utvärdering av det svenska systemet

This paper is a critical evaluation of the Swedish system with special mediation. The district court has the opportunity, in cases that are amenable to out-of-court settlements, to refer the dispute to special mediation. However, this is extremely rare, even though the legislature expressed a desire to increase the use of alternative dispute resolution. In 2011, a series of measures were taken to increase the use of mediation and strengthen mediation attractiveness. What effect can be inferred from these actions today, over three years after their introduction? This study analyses the main reasons offered for why mediation is not used more, and what should be done to increase the use of mediation.

Håkan Juholt och Skavlan : En uppsats om pratshowens möjligheter och begränsningar för partiledare i förtroendekris

This essay examines the appearance of Ha?kan Juholt, former party leader of the swedish social democratic party, in the norwegian/swedish talk show Skavlan, during Juholt?s crisis of confidence in the autumn of 2011. In this appearance it is clear that Juholt is badly treated by the host Fredrik Skavlan, and his guest, writer and journalist Linn Ullmann, while the audience seems to applaud and laugh at Skavlans and Ullmanns criticisms.The purpose of this essay is to investigate how, and why Juholt is treated in this way, and which rhetorical strategies Skavlan and Ullmann employ to create community between them selves and their audience. To understand this occurrence it is important to study Juholt?s rhetorical situation, and which conditions his lack of confidence creates for his appearance in Skavlan.

Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans

This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.

Ladies av Mara Lee? en chick-lit som alla andra? : En narratologisk och diskursanalytisk studie av Ladies och chick-lit-genren.

My thesis deals with the novel Ladies, written in 2007 by the Swedish author Mara Lee. When published, it was received as a book belonging to the chick lit genre but still got good reviews. This combination is really unusual and awoke my interest in the novel. My thesis is therefore an analysis whether Ladies can be considered a chick lit novel or not, and in what way it is similar to or differs from the genre. I start my thesis with an overview of former research of chick lit and what earlier was called trivial literature.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.

Berättelser om hjälpsamma samtal En narrativ studie om verksamma processer I terapi och behandling

The title of the study is: "Stories about helpful conversations - a narrative study of active processes in therapy and treatment." The purpose of this study was to examine clients' stories of what has been helpful to them in therapy / treatment. The study has been made in light of the ongoing discussion in society about the requirements for empirical studies within welfare areas. The choice to make a narrative study comes from the desire to have clients' own stories at the centre of what has been helpful in the therapeutic process. The author has interviewed and talked with four people (clients) who told us about their experiences of therapy / treatment. Narrative research methodology is based on people's life stories.

Internal Quality Audits as an Improvement Tool

A large proportion of businesses around the world is today ISO 9001 certified and is consequently conducting internal audits on a regular basis. It has however not been possible to conclude that internal audits always add value to the organisation, despite the large utilisation of this tool. Some authors, e.g. Alic & Rusjan (2010) and Wealleans (2000), mean that there are possibilities that internal audits may be used as a value-adding improvement tool. This has led to the emergence of this master?s thesis.The purpose of the case study was therefore formulated to examine how internal quality audits can be made more effective and used as an improvement tool.

Ung lust och könat tvång : Representationer av sexuellt handlingsutrymme i svensk samtida ungdomsroman

This Master's thesis explores representations of sexual agency in contemporary, Swedish novels for young adults. Using a representational theory approach the thesis analyzes 24 novels published in 2000 ? 2013. Addressing the following research questions: how is sexual agency constructed and regulated relative to gender performativity in Swedish novels for young adults? How are situations of sexual abuse and sexual ?grey zones? (situations that border on abuse) represented and being made intelligible in the texts? What are the consequences of representations of sexual agency? In the readings of the novels discourse analysis and theories on cultural representation and power have served as the critical points of entry, as well as the methodological basis for the study.

Europas gräns under en säkerhetspolitisk förändring? : En fallstudie om säkerhetspolitiken vid den europeiska gränsen mellan 2007 och 2010 samt en prövning av Köpenhamnsskolans säkerhetiseringsteori

The purpose of the essay is both to bring forward the threats images, sectors, actors and referents that can be found at the European border between 2007-2010 and to explore whether they change during this period. Furthermore, the essay also intends to review the Copenhagen School?s theory of securitization. The analysis of the essay will be done on the European commission?s ?Enlargement Strategy and Main Challenges?, a rapport that focus on the European border and its enlargement.

Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.
