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.
IT-säkerhetsevaluering i ackrediteringssyfte inom det svenska försvaret.
Detta examensarbete har genomförts på uppdrag av Försvarets Materielverk (FMV). Det påstås att evaluering av komplexa/sammansatta system är svårt, om inte omöjligt. Common Criteria (CC) är en ISO/IEC-standard för evaluering av produkter och system. Även Information Technology Security Evaluation Criteria (ITSEC) används för samma ändamål. Jag har undersökt vad som är möjligt och denna uppsats beskriver alternativa evalueringslösningar med hjälp av CC/ITSEC, dock primärt enligt CC; där fokus hela tiden vilar på ackreditering av system och produkter inom det svenska försvaret.
Jämförelse av vertikala accelerationer av järnvägsbroar för höghastighetståg.
Under de senaste decennierna parallellt med klimatdiskussionen har det vuxit fram ett stort intresse för höghastighetståg och en förbättrad infrastruktur i Sverige. I delar av Europa men speciellt i Kina och Japan har utvecklingen av höghastighetståg fått ett enormt lyft. Ett problem vid höjda tåghastigheter är att broarna vid en kombination av låg massa och låg egenfrekvens riskerar att orsaka resonans och höga accelerationsnivåer vid passage.Ballastspår är namnet för det traditionella järnvägsspåret i Sverige. Ballastfria spår är motsatsen till ballastspår. Andra namn för ballastfria spår är Fixerat spår eller slab track.
Utvärdering av laserhybridsvetsning vid applicering på lyftarm
Detta examensarbete har varit ett samarbete mellan Esab AB, Trumpf GmbH och Hiab AB, där laserhybridsvetsningen applicerades på lyftarmar till hydrauliska lyftkranar, för styckegods. Arbetet har bl.a. gått ut på att utföra svetsprover av kälfog på 5 mm tjock plåt och jämföra solidtråd med rörtråd. Utifrån proverna togs det fram en WPQR (Welding Procedure Qualification Record), ett svetsdatablad som ska vara tillämpbar för att bygga liknande procedurer i produktionen. WPQR-bladet togs fram genom att sammanställa exempel på svetsdatablad i standarderna EN ISO 15609-1 och EN ISO 15609-4, som riktar sig till konventionell bågsvetsning respektive lasersvetsning.
Pallhantering på Findus - Flöden , problematik och alternativ
The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.
Utlägg för annans räkning : Ersättning för utlägg vid representation inom svenska verksamheter
Background: According to us, obtaining reimbursement of expenses in connection with a representation is a ?forgotten? process, and we therefore find it interesting to look further into. In some cases we have not claimed for compensation since we consider the process as too complicated or that we lost the original receipt. Ernst & Young (2009) say in their research that within the financial management area, Swedish operations loses billions of Swedish crowns due to bad routines. Okada and Hoch (2004) mention that if time were not considered as a resource, time would not be a hinder.
En kvalitativ studie om hur personer med utländsk bakgrund upplever att integrationen fungerar i Sverige
Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.
Upplevelser av rovdjursturism : en studie av resereportage
This essay contains a discoursive analysis of fifteen travel reports from five of the largest papers in Sweden. The travel reports contains recaptions from wildlife tourism experiences were the predators are the main target, or at least one of the main targets. Seven of the reports are from Sweden and eight of them from Russia, Rumania, Finland, Turkey and the United States. Predators in this essay aims to those in Sweden called ?the big five?, these are: bears, wolves, lynxes , wolverines and golden eagles.
Spåret mot parken : en gränsöverskridande stig mellan torg och park i Norra Sorgenfri
My thesis is a combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
En analys av SCA Skog AB's metod för egenuppföljning av gallringar :
A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.
Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
Skottbetning på granplantor i Kolmården : omfattning och påverkande faktorer
In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots.
For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history.
The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.
Orsaker till mekaniska skador på nötslaktkroppar som uppstått under transporten till slakteriet eller på slakteriets stall :
In the Swedish abattoirs there are assistants that judge the slaughtered animals in regard to diseases and injuries. All diseases and injuries assign different codes. This master?s thesis is about code 42 which means injuries of different kinds like for example bruises etc. These injuries have risen during the transport from the farm to the abattoir lairage or during the stay at the lairage before slaughter.
