Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Framtidens småhusindustri. En femårsvision över den svenska småhusmarknaden.
This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.
Åldern i fokus : En studie om hur svensk rätt påverkas av EG-rättens reglering av åldersdiskriminering i arbetslivet
Sweden is a member of the European Union (EU) since 1995. The association results in considerable proportions of the European law, also called EC-law, for Sweden. The legal system has precedence above Swedish law, which forces our national court to take consideration into and interpret the law in the light of EC-law.Sweden doesn?t possess a general legislation of discrimination. An appointed committee investigates the matter and the requirement of a common law, including all discrimination prohibits.
Ekonomisk utvärdering av betonggjutformar
This report will try to evaluate the use of rented concrete casting moulds, which are used to build walls and system of joists. The evaluation is only examining the economical aspects.The cost of using concrete casting moulds is a big part of the total production expenses. Therefore it is important that the calculated price not exceeds the final costs of the casting moulds. The calculated price is the price used in the process of making an offer.The evaluation consists of a comparison of the calculated price and the final costs for three building projects. It also evaluates the exploitation of the concrete casting moulds for each project.The report is made by Sven Gynne and Anders Alexandersson at School of Engineering, Jonkoping University, in cooperation with PEAB Jonkoping.
Trädgårdar på tak- och gårdsbjälklag :
The purpose of this thesis is to collect knowledge of techniques and materials for planning roofgardens.
Gardens built on top of buildings is not a new phenomenon, already in the beginning of the century architects were experimenting with roofgardens. During the Modern Era roofgardens appeared as a part of the design and worked well together with flat roofs and the ideas of light, air and greenery. Today the most common kind of roofgarden is on a ground-level joist that hides parking or other underground functions.
The most important difference between planning a roofgarden and a garden on the ground is the limitation of the load of the roofgarden. Plants, paving-material and equipment must be chosen with this in mind. A light and thin layer of soil demands plants with small needs for water and nutrition.
Objektdetektering i SAR- och IR-bilder
This report treats detection in IR-pictures taken from airplanes over the ground. The detection is divided in two parts. First there is a detection with filterkernels with the task to point on targets and objects that look like targets. The second part is a discriminator that demands more calculations and has the task to sort out the false alarms from the discriminator. Both the detector and the discriminator contain thresholds thats been trained from trainingsets of data.

Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
Organisationskultur : Ett kritiskt granskande genom modernism, symbolism och postmodernism
Organizational culture is subject of a great debate nowadays and there is especially three schools which affairs its nature of reality; modernism, symbolism and postmodernism. This thesis is built upon a case study about the organization Idé & KunskapsCentrum, which experience various cultural issues. Observations made during visits in the organization environment forms the ground on which discussions about different perspectives are made regarding organizational culture.The thesis describes and investigates the subject of organizational culture and its relationship to human behavior in organizations. Furthermore, I discuss and analyze organizational culture from the three different perspectives, in order to present a critical view on the subject for the reader.The thesis is based upon a case study about the organization Idé & KunskapsCentrum. A qualitative research method has been conducted with data collected especially from an ethnographic study, but also via semi-structured interviews.
Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island
This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.
Virtuella vävnadsobjekt för medicinska träningsapplikationer
This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.
11 september under elva år : En kvantitativ studie av Dagens Nyheters rapportering om 11-septemberattackerna i USA på årsdagarna 2001-2011
Syftet med denna uppsats är att undersöka om nyhetsvärderingen har ändrats under åren 2001-2011 i Dagens Nyheters nyhetsrapportering om attackerna mot USA den 11 september 2001. Detta har vi gjort genom att studera bevakningen av årsdagarna för terrordåden. Dagens Nyheter valdes eftersom tidningen har en tillräckligt stor redaktion och tillräckligt med resurser för att täcka internationella händelser. Vår teoretiska ram utgörs av tre nyhetsvärderingsteorier. Med dessa som utgångspunkt utformade vi variabler och gjorde en kvantitativ innehållsanalys.
A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures
Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.
Val av värme- och ytbehandling
Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.
It takes a new way to think to solve the problems we created by the old way to think ? Social welfare secretaries thoughts about family-placement on institution
The purpose with this essay is to take part of the process when a family is placed on the family-institution, Trollbacken. We want to know what makes the social welfare secretaries place a family in institutional care. Has Trollbacken lived up to the social welfare secretary expectations and are the social welfare secretaries following Trollbackens recommendation regarding the follow up treatment. We also want to know to what value the social welfare secretary assigns Trollbackens investigation and are they able to see changes in the family due to the placing on Trollbacken. The method is qualitative and is based on interviews from six social welfare secretaries that work around and in West Sweden.
