Pinus contorta susceptibility to Heterobasidion spp. : a study of stumps, roots and artificial spore infections of stumps
The Lodgepole pines susceptibility to Heterobasidion spp. was investigated in three parts ofthis study. In the first part, discs from freshly cut stumps were collected and analyzed to seeif the fungi can spread and grow naturally in Lodgepole pine stands. In the second part, rootsamples were collected from Lodgepole pines planted in former infected Norway sprucestands to see if the fungi can spread through root contacts. For the third part, new stumpswas created and artificially infected with spores of both the S?type (H.
AVVIKANDE KROPPAR I DET SAMTIDA TV-UTBUDET
This thesis discusses the representation of bodies in todays non-fiction television in Sweden. I have chosen to focus on deviant bodies (sexual, deformed or unhealthy) on display in reality-shows and documentaries on SVT, TV4 but especially on the commercial channels TV3 and Kanal5. Also discussed are the viewers emotional and bodily reactions. Altough these shows are different from one another in many respects, I argue that there is also a common thread between them. From a sociological and cultural perspective, and with help of some historical examples, I try to illustrate how we view these shows and what their function is.
CSR & Etik: En tillämpning av normativ etik på CSR i praktiken
The neo-classical conception of the market place does not provide a framework to account for ethical or moral action. As a result, the neo-classical model is unable to explain the impact of ethical and moral issues on business sustainability present in the modern economy. To address this limitation, this thesis investigates whether theories of ethics can help explain the motivations and actions of stakeholders within the field of Corporate Social Responsibility (CSR). In addition, the thesis explores whether theories of ethics are presented differently within aspects of the stakeholder model. Semi - structured interviews were conducted with various stakeholders within the CSR sector, including a NGO, a commercial firm and a CSR consultancy firm.
Kan dans ge unga kvinnor livskraft, styrka och självinsikt
The first main purpose of this essay is to describe the situation of young women today here in this part of the world concerning influences from commercial media.The second purpose with this essay is to investigate if dance could be used as a tool against all these sterotyped and superficial pictures and ideals in the industy of commersial media.With some questions I also want to get closer to the answer if dancing is a way for young women to get insight knowledge. I also describe women from dance history who experienced that dance filled them up with energy but also environment where there was oppression.This essay has a gender perspective.The methods are manly based on literature studies but information is also gathered from the Internet and from one film.My results are that dance is a very constructive way to give the young woman that force which is needed when meeting media pictures everywhere. It gives her self-confidence, body awareness, joy and strength in life..
Mobilt community - Bygga själv eller hjälpa till? : Kommersialisering av en plattform för användardriven karttjänst i mobiltelefoner
Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.
2001: ett e-äventyr : Implementering av e-böcker i det digitala biblioteket
Rapid development in the realms of electronic publishing has had a profound impact on information services in general and the academic library in particular. Since mid 1990´s an increasingly number of scholarly journals and other information resources have been made available electronically. Electronic books are the newest electronic service in the hybrid library and can be seen as the third wave in the digital library. Although electronic books have for a long time existed as electronic texts such as digitalized classics or other texts in the public domain, it is not until recently that e-books have been distributed and packaged in a commercial form. As more e-book models are being developed, libraries are being forced to take e-books into consideration when planning their information services.The aim of this master thesis is to describe the first stage of implementation of the new electronic media, the electronic book or e-book, in Swedish academic libraries.
Urban green in Vientiane, Lao PDR : a minor field study
This is a Minor field study addressing the current situation
in Vientiane, Laos where focus lies on the green structures
past, present and future.

this there is a increasing development. The once peaceful
capital known for it?s lush and green environment is
standing in a crossroad where important decision must
be made to preserve valuable areas. During 8 weeks inventories and observations where made resulting into a
proposal for future development. The proposal is divided
into three parts.
The urban fringe and surrounding landscape are still
quite undeveloped and have a great potential of green
wedges etc.
The city of Vientiane and the green network linking important recreational, commercial and cultural places.
Detailed proposal over certain green objects such as
parks and squares..
Gödslingsstrategins inverkan på Holmen Skog, Umeå distrikt
This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.
Analysmetoder för rörsystem
The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

Designteori i praktiken : En undersökande fallstudie om hur designteori manifesterar sig i praktiken
New technologies and new consumer behaviors are having a large impact on mediacompanies. The biggest change is in the behavior of the younger demographic whereold platforms like television are abandoned for new online platforms. In this newworld, media companies and organizations need new tools and business models tostay competitive. One such tool is Design Thinking, a term used to describe a cognitivedesign-specific set of activities used during a design process. It has been popularizedin commercial areas and there the term is used to describe an applicable workflowused to promote the skills required to use Design Thinking.

Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and maintenance costs and costs for the fuel and ash handling.

Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
