Kan risken för spontan contortaföryngring elimineras genom hyggesbränning? :
Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
Pooling som affärsstrategiskt koncept: en fallstudie vid Volvo Aero Corporation
Marknaden för flygmotorunderhåll har blivit allt mer konkurrensutsatt sedan nya aktörer börjat ta marknadsandelar. Det kärvare marknadsklimatet har främst drabbat de små fristående underhållsleverantörerna. En av dessa små fristående underhållsleverantörer är Volvo Aero Corporation, VAC, i Trollhättan. Ett problem vid flygmotorunderhåll är behovet av reservmotorer. Kapitalkostnaden för inköp av reservmotorer är mycket hög, samtidigt som bristkostnaderna också är mycket höga.
Val av tidpunkt för markberedning vid naturlig föryngring under skärm av Pinus sylvestris i Svealand : Timing of scarification when using natural regeneration in seed tree stands of Pinus sylvestris in Central Sweden
This thesis is built on a field study that was carried out in two seed-tree stands near by Götbrunna in Uppland, Sweden. The aim was to examine if scarification carried out in spring time could generate a more dense seedling establishment when using natural generation, than scarification carried out in autumn. It was also investigated whether there were differences in mortality the first season between the two plot-types. Plots were established block-wise with 50 blocks (pairs) on each site. The spring scarification was made with a hoe during 22-23 of April.
Modig som ett lejon och listig som en räv : historieskrivningen kring Monaldescos avrättning sett ur Machiavellis fursteteori
Queen Kristina of Sweden (1626-1689) is a person who has been widely studied during the years. She is known as the monarch who left the Swedish throne and the protestant faith in favour of the catholic Rome. Even though Kristina left her powerful position as queen of Sweden she never gave up her dignity as a sovereign. My purpose with this study is to analyse historians and other scholars different research concerning Kristina?s notorious execution of Monaldesco in 1657.
Kronandelsrelaskopering - metodoptimering och mätfelsstudie : metodoptimering och mätfelsstudie
I dagens skogsbruk bedöms gallringsbehovet utifrån gallringsmallar som ger rekommendationer baserade på avvägningar mellan biologisk kunskap, ekonomiska faktorer och risker. Gallringsmallarna är anpassade efter tänkta produktionsskogar och kan således vara bristfälliga i andra fall. Därför behövs en effektiv bedömningsmetod som fungerar i både homogena och heterogena bestånd. Studier har visat att tallens (Pinus sylvestris) grönkronandel har påvisad effekt på diametertillväxten och genom att uppskatta denna kan ett direkt mått ligga till grund för bedömning av gallringsbehov, istället för det indirekta måttet grundyta, som nuvarande gallringsmallar är utformade efter. Tanken är att undvika produktionsförluster genom att gallra innan grönkronan hissats upp alltför mycket.

Syfte: Vårt syfte med föreliggande arbete är att, mot bakgrund av existerande forskning, beskriva försvarsstrategier vid fientliga företagsförvärv. Vi avser även att undersöka ett antal fientliga förvärvserbjudanden och därigenom utreda vilka försvarsstrategier som förekommer och i vilka kombinationer dessa används. Målsättningen är även att göra en bedömning av vilka försvarsstrategier som är mest effektiva vid fientliga angrepp. Metod: Vi har främst använt oss av en kvalitativ metod. Uppsatsen kan delas in i tre olika metodiska faser.
Att utforma den perfekta skandalen : En studie av hur Expressen rapporterade om SD-skandalen i november 2012
Title: How to Construct the Perfect Scandal ? a study of the news reported by Expressen concerning the SD-scandalAuthor: Linnea IvarssonThis C-paper presents the incident concerning the political party Sverigedemokraterna in Expressen in November 2012. The newspaper was the main source of the news reporting with the mobile phone camera film from the occurance and led the way of the news reporting in Sweden about three party members.The paper investigates how the story telling of the so called SD-scandal was constructed, using Critical Discourse Analysis as the analysis method combined with selected parts from the analysis method of critical linguistics. The theories that have been used to establish the results of the analysis are Critical Discourse as a theory based on Norman Fairclough and Teun A. van Dijks theoretical keystones combined with Sigurd Allerns and Ester Pollacks theories and schematic point of view on the constructions of political scandals in media.With the theories and analysis methods above mentioned the results turned out to confirm the theory about how political scandals in media are constructed and designed with certain strategies and agenda.
Produktkoncept: lekhjälm i vintermiljö : ett nytt produktsortiment
A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.
Hjortpark, kronoskog och ladugård : En bebyggelseundersökning av Skyttsie Hage på Skanörs ljung
This essay is about a deserted medieval habitation called Skyttsie Hage which is located in the south of Sweden in the Scania province where it lies on a moor on the Falsterbopeninsula. Remains of five to six larger buildings have been found here with a surrounding earthwork, although it's not known for sure what kind of habitation they have been part of. Local folklore from the 17:th century states the area as a place where pirates lived, and that this was the reason for it's devastation. Another says that there once stood a breedingfarm belonging to the danish crown. Archaeologists have made several speculations which includes a deer park, a royal estate, an isolated farm or a smaller village.
Utveckling av biotopdatabas och tillämpning av landskapsekologisk analys i Huddinge kommun
På grund av ökad urbanisering och exploatering av grönområden i stadsnära miljöer fragmenteras och reduceras arters habitat vilket bland annat ligger till grund för den globalt minskade biologiska mångfalden. För att stärka och förbättra arters möjlighet till spridning i landskapet, och därmed säkra en hög biologisk mångfald, efterfrågas insamling av data och utveckling av nya metoder för att identifiera ekologiska kärnområden och för att analysera habitatnätverk. Syftet med den här studien är därför att 1) kartera och sammanställa biotoper i en biotopdatabas utifrån tolkning av infraröda flygbilder med digital stereofotogrammetri, 2) undersöka olika metoder att samla in data med hjälp av laser- och höjddata, och 3) att tillämpa landskapsekologisk analys på underlag i biotopkarteringen.Resultatet validerar att tolkning av infraröda flygbilder med digital stereofotogrammetri är en utmärkt källa för att kartera biotoper som medför en tolkningsnoggrannhet på 86 %. Valideringen av kateringen genomfördes med fältkontroller som utvärderades i felmatriser. En metod har även undersökts baserat på tidigare studier för att uppskatta busk- och krontäckning med hjälp av laserdata, men eftersom det saknas validering av resultatet bör den användas som en indikator för att visuellt uppskatta busk- och krontäckning i dagsläget.
Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling
Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.
När en norsk del av Danmark tillfogades Sverige : en ingång till att förstå bohuslänska identitetsföreställningar 1662-1668
This essay discusses the Nordic region Bohuslän the decade after it became "Swedish" in 1658, during what I call the region's "transition period". The wide cause of the study is to show how the traditional understanding of this state shift (and of state shifts in general) need to be problemized and understood in the light of the state conditions of Early Modern Europe. By examine court protocols from the local-court of Orust and Tjörn (one of five local courts in contemporary Bohuslän) and the local noble's writings to the Swedish parliament, a tricky mixture of references to different territories gets observed and analyzed.To approach the difficult identity problems, I have assistance in Peter Sahlins' conclusions from his study of the French-Spanish borderland during the same period. Especially helpful are his identity schemes by which he (inspired by the Norwegian anthropologist Fredrik Barth) supposes that each identity originates from a counter-identity. This study ends up in an attempt to reconstruct the landscape of identities and counter-identities found in the sources, according to professor Sahlins' schemes.
From industrial past to sustainable future : Arboretum Lövholmen; generating trees for a greener future
Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society.
We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen.
Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress?
The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.
Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?
Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.
Vintervegetation genom ljus : om hur man med belysning kan framhäva avlövad vegetation i offentlig stadsmiljö
Use of lighting is crucial to make public urban
places available during dark hours. Landscape
architects participate in planning of lighting, but
during our education there is very little taught on
the subject. Through this study we approach the
subject of lighting by looking into lighting methods
for urban plant materials during winter.
In this thesis we look into ways to emphasize the
visible characters and experiences of urban plants
during winter season using light. Target audience
are landscape architect students and landscape
architects without knowledge of lighting. The part
of the thesis that describe basic conditions for, and
visual characters of plants can be useful to lighting
designers without knowledge in this subject.
Working methods used were the following:
? Pre-study about light and lighting techniques
through literature and dialogues.
? Compiling important visual winter plant
characters through photography and literature.
? Outdoor light experiments with plants.
