Vattensork och åkersork - skadegörare i svensk fruktodling

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.

Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Hälsa och funktion i kvalitetsregistret för uppföljning av cererbral pares - CPUP : En genomlysning utifrån den internationella klassifikationen av funktion, funktionshinder och hälsa för barn och ungdom

Abstract:Objective: This study aimed at describing the health concept in the Swedish follow up programme for cerebral palsy (CPUP), with main focus on how aspects of participation is expressed in the agenda of the programme. Design: Document analysis: The home-page of CPUP was searched for three types of written material; references to the nature and aim of the programme, protocols used for data collection and abstracts from articles and reports on the list of publications. Within these all expressions of health, with bio-psycho-social understanding of the concept, were extracted and condensed with manifest content analysis. The meaning units obtained were linked to the International Classification of Function, Disability and Health ? Child/Youth (ICF-CY).

Biomekanisk analys av patientlyft i team

Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique among care workers. Objectives: The aim of the study was to identify any advantages or disadvantages with MA?s lift, regarding shear and compression forces in the L5/S1 disc.

Termisk Vattenpump

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Cykelolyckor i korsningar : Hur kan trafiksäkerheten förbättras?

Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The  purpose  of  this  paper  is  to  highlight  bicycle  accidents  at  intersections  and  to  suggest improvements  in three accident-prone junctions  in Stockholm.  This is  achieved  by  the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.

Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use

The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

Konsten att tala om böcker : Bokprat ur ett retoriskt perspektiv

In this study the book talk is examined as a communicative act with a purpose to convince according to an under-lying intention to promote reading. I follow the book talk?s way from an idea of the book talker (and the library) to the reception of the audience, with the aim to understand how to talk about books in an engaging manner. More specifically, the rhetorical situation and the purpose of a book talk, the performance and the means to arouse and retain interest in the book talk as a speech and in the books themselves are examined and the impact of the book talk on the audience.The empirical material consists of observations of two different book talks (both directed to children) and interviews with the two different book talking librarians and a few of the children from the audiences to both book talks. The theoretical framework consists of rhetorical theories from both antique and modern times and I perform a rhetorical analysis of both book talks.

En surrealistisk soppa? En komparativ studie av Stefan Hammaréns sopptrilogi och surrealismens litterära kriterier

The purpose of this essay is to establish whether the so called ?soup trilogy?, med en burk soppa (2001), konservöppnare bok (2003) and på burklös mark (2005), written by Swedish-speaking Finn Stefan Hammarén is to be considered as surrealism or not. The methods used to determinate this is close reading, a technique used for finding a text?s distinguishable traits, and comparative analysis. First of all, the criteria of surrealist literature found in André Breton?s (1896-1966) Surrealist Manifesto, and other sources, as well as the criteria for the surrealist literary technique cut-up are presented and evaluated accordingly.
