Målet med detta examensarbete är att minska risken för olyckor där grävmaskiner, med borr- eller pålmast monterad, är inblandade. För att kunna uppnå detta mål, har ett beräkningsprogram skapats som definierar ett säkert arbetsområde innan ostabilitet inträffar. Detta har gjorts genom att studera tidigare forskningsarbeten inom området samt verifiering av beräkningsprogrammet med hjälp av en fallstudie och data om maximal lyftkapacitet för grävmaskinen..

This degree project summarizes five years of education at the landscape architecture program at the Swedish University of Agriculture Sciences, SLU, Alnarp and the School of architecture at Royal Institute of Technology, KTH, Stockholm. The project has been carried out by Lovisa Berg and Per Crona in collaboration with DRIFT Scenkonst. This master project is based on the ongoing transformation of a former mining site in Ställberg, Bergslagen situated in central Sweden. The organization DRIFT is in the process of recreating to former industrial mining site as a green cultural center. Their field of artistic examination concerns existential questions connected to the site. The aim is to offer a place for both performing and experiencing contemporary performing arts in Bergslagen. Our objective is to contribute to the growth of the performing arts project and to demonstrate in concrete terms how a conversion of a mining area can be completed, while taking into account both its history and its new function.

Dagens företag och organisationer måste ständigt förändra och förnya sig för att kunna överleva. Många av de studier som genomförts, visar att implementeringar av strategiska beslut i företag och organisationer ofta misslyckas och implementerings-arbetet beskrivs av många forskare som en konst snarare än en vetenskap. Förändringsarbetet och i synnerhet implementeringsfasen är det som fokuseras i detta arbete. Det finns många olika orsaker till varför implementeringsarbeten misslyckas, men genomgående så lyfts den interna kommunikationen fram som en ytterst kritisk faktor. Detta är orsaken till att vi på djupet studerat detta ämnesområde.

The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

Forestry has three main aspects to take into consideration today; economical, ecological and socio-cultural. In order to reach the broad policy goals for sustainable forest management, an increased variety of management approaches are requested. Today clear-cutting is the only method used in 96 % of the managed forests in Sweden. The Swedish National Board of Forestry has therefore initiated a project in order to investigate and develop Continuous Cover Forestry (CFF). This study is a part of this project.

The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein. The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.

I en värld med ökande globalisering utsätts företagen för mer och mer konkurrens. Vilket medför att företagen ställs inför högre krav på effektivitet och produktivitet för att skapa och bibehålla sin konkurrenskraft. För att upprätthålla effektivitet och produktivitet krävs emellertid underhållsarbete för att stödja de processer som ska möta kundens behov. Detta underhållsarbete medför därför ett behov av att anskaffa reservdelar, en process som bör bedrivas effektivt för att undvika produktionsstopp.Studien har genomförts på Boliden Minerals AB i Kristineberg, vars reservdelsförsörjningsprocess inte upplevts som optimal. Detta medförde att studien ämnat till att studera den nuvarande reservdelsförsörjningsprocessen, att effektivisera reservdelsförsörjningsprocessen och att utreda vilka utmaningar som kan uppstå vid en förändring av denna samt hur dessa ska kunna hanteras för ett effektivt förändringsarbete.

The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.

The aim of this thesis was to develop an objective and automatic method for identifying capillaries in microscope images of the skin. Furthermore, statistical data about the identified capillaries and the capillary distribution should be computed and stored in a database. The method was implemented using the platform independent programming language Java. An analysis of microscope improvement using various polarization filter setups and wavelength filtershas also been performed, as well as a pilot study of the effect of applying a local anaesthetic cream on the skin. The method is developed and aimed at research on various pathological skin conditions affecting the capillary distribution.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Målet med denna uppsats i landsbygdsutveckling är att undersöka hur landsbygdsbor upplevt den serviceförändring som ägt rum under deras livstid, hur det påverkat servicens tillgänglighet och hur de förhåller sig till servicen. Uppsatsen baseras på kvalitativa intervjuer med sju personer ifrån Ramsberg, i Bergslagen och som huvudsakligen analyseras utifrån Habermas teori om det kommunikativa handlandet. Studien visar att upplevelsen av förändringarna är kopplad till om förändringarna upplevs ske utifrån ett kommunikativt handlande eller kommer som en tvingande kraft utifrån abstrakta idéer. Den visar även att upplevelsen av servicen påverkas av vilka möjligheter till social interaktion den medför där det kommunikativa handlandet kan ske..

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.
