Stråkröjning och skogsbränsleuttag i unga granbestånd jämfört med konventionella metoder : Två fältstudier vid Asa försökspark
Den här uppsatsen grundar sig på två fältstudier i nyutlagda demonstrationsförsök på Asa försökspark som ska användas i utbildningssyfte. Studie 1 bestod av försöksytor i ett 13 år gammalt bestånd som röjts till samma röjningsförband men med tre skilda metoder; motormanuell selektiv röjning, maskinell stråkröjning och som en kombination av bägge metoderna. Syftet var att beskriva det nuvarande tillståndet, simulera fram prognoser för beståndsutvecklingen och beräkna dess ekonomiska konsekvenser fram till och med första gallring och jämföra de olika metoderna med varandra. Studie 2 bestod av försöksytor i ett 23 år gammalt eftersatt bestånd där fyra olika åtgärder testades; ingen röjning innan gallring, underröjning i samband med gallring, sen röjning och skogsbränsleuttag. Syftet var även här att jämföra de olika metoderna med varandra genom beskrivning av det nuvarande tillståndet, göra prognoser för beståndsutvecklingen och beräkna dess ekonomiska konsekvenser vid första gallring och i den här studien även fram till och med den andra gallringen.
Baltic 21 kontra Helcom : Hållbarhet eller Modernisering
The purpose with the essay is to point out how the main differences of the Helsinkicommission, Helcom and Baltic 21 can be explained from a general perspective and with a specific focus on two of their ongoing projects: Baltic 21 Lighthouse projects and The Baltic Sea Joint Comprehensive Environmental Action Plan. And to investigate how the organisations them selves formulates the purpose of the two projects. This will be an indication on why environmental problems are handled with in a traditional matter although the rhetoric of the environmental politics is permeated by the concept of Sustainable Development.This dilemma is being treated from the theoretical approaches of Ecological Modernisation and Sustainable Development and linked to how these organisations actually carried out their work and how the historical heritage have a role to play in this complex of problems. The results of the essay shows that concrete differences exists in the way that the two organisations are constructed and how their ongoing projects are designed and formulated. These differences can be derived to the theoretical platforms Ecological Modernisation and Sustainable Development and be explained by in witch political context the organisations were created.
Synen på serier ? en studie av folkbibliotekariers syn på serier och deras hantering på biblioteket.
The purpose of this thesis is to study the attitude towardscomics among librarians as well as their personal image ofthe overall attitude towards comics among librarians and themanner in which the attitude of the librarians affects how thecomics are treated in the library.I have performed this study with a qualitative approach andhave interviewed a total of five librarians working in twodifferent libraries.I have founded the theoretical base for my research in anumber of historical attitudes towards comics and thencompared these attitudes towards the answers given in theinterviews as well as prior research found in three theseswritten by Magnus Johansson, Sarah Johansson and KarinEsaiasson.The results of the study is that traces of most of thehistorical attitudes can be found among all of the interviewedlibrarians but that none of them are harboring any negativeattitudes towards comics themselves. On the other hand thestudy does imply that the image of the librarian who onlythinks that comics are meant for children is still very muchalive in the collective subconscious of the librarians.The study also shows that while librarians of today tend tohave a neutral outlook in comics the historically subpartreatment of comic in the libraries and the subsequent lack ofacademic support on the subject have made it necessary forthe librarian in charge of the comic-section to have apersonal interest/liking for comics to be able to do a goodjob..
Kommunägd skog i Sverige : en enkät- och intervjustudie av de tätortsnära skogarnas ekonomiska och sociala värde
This Masters thesis is performed at the request of the National Board of Forestry in order to investigate how the Swedish municipalities use their forests. The study is of general character with emphasis on the social values of the forests.
The municipalities? purposes with their forests have varied over time, but lately the social aspects have been recognised as interesting. The social values of the forests can be defined as the values from the forests that contribute to the wealth of humans. This has socio-economic importance for the municipalities.
The study was performed as a quantitative questionnaire survey, complemented with qualitative interviews.
Läroböcker och genus : En kvalitativ studie av läroböckers beskrivning av genus i religionerna islam och hinduism
The purpose of this paper is to examine how gender in Islam and Hinduism are described in textbooks for high school. The study was conducted using a qualitative content analysis and also using a feminist gender theory and postcolonial feminist theory. All textbooks are written or revised after 2011 when The Swedish National Agency for Educations? new curriculum came into force. Previous research in this area shows that it is most common that gender is treated in isolated parts within the chapters, but that there are textbooks that allows the gender perspective permeate the entire text.
Den svenska debatten om Natos bombningar av Jugoslavien 1999
Purpose: The purpose of this work is to investigate teachers' professional attitude to homework as a method. The study will also provide answers to the purpose for which the homeworks are used in teaching and if the individual circumstances and needs are met by this method.Method: Qualitative research was conducted through interviews with four teachers from three different schools. In addition, published surveys were used in support of reasoning.Results: Neither the curriculum or the syllabus mentions homework. There are no directives for how much time should be dispensed with and the extent of a homework should be. In teacher training literature the homework is not discussed.
Opioid-inducerad obstipation i samband med postoperativ smärtbehandling : Förekomst och förebyggande åtgärder
Objective: The objective was to examine the incidence of constipation, and the preventive measures taken in relation with postoperative pain treatment with opioids at two orthopaedic surgery wards.Methods: The participants were patients that had undergone surgery in the back, hip or thigh. They were selected through systematic selection and a total of 46 electronic health records were examined. The factors investigated and tested for correlation with constipation were the usage of laxatives, daily fluid-intake and early mobilisation.Results: Totally, 26.1 % of the patients became constipated, and laxatives were prescribed to 65.2 % of the patients. Doctors prescribed 53.3 % of the laxatives, nurses 33.3 % and for the remaining 13.3 % it was uncertain who had written the prescription. Usage of laxatives seemed to cause constipation (p=0,025), whereas there was no correlation between constipation and early mobilization.
Seriemediet i bibliotekspressen 1960-1999
The purpose of this Master?s thesis is to study how the comics have been evaluated and debated in the Swedish library press from 1960 to 1999. Have they been seen as something good or something bad? What arguments have been put forward against them or in their defense? What kinds of development can be seen over time? The point of doing this, is of course that evaluation always plays a crucial part in library work. By studying how a "new" medium or art form has been evaluated in the past, we can hopefully gain a greater understanding of how today?s newcomers should best be treated.

Husväggar av massivträ: En kostnadsjämförelse
Trä är och har sedan länge varit en av Sveriges mest exporterade råvaror. Branschen sysselsätter idag omkring 100 000 människor i landet. I samband med de senaste årens miljödiskussioner bör husens uppbyggnad diskuteras. Syftet med detta examensarbete är att främja husbyggnation i massivträ som de senaste åren fått mer publicitet inte bara på den svenska marknaden men också i centraleuropeiska länder.Frågorna i detta arbete handlar om att identifiera de vanligast förekommande ytterväggskonstruktionerna och jämföra deras materialkostnader samt kostnader för arbete vid montering. För att ha kunnat göra en rättvis jämförelse har BBR?s energikrav varit den gemensamma nämnaren för ytterväggskonstruktionerna.Frågorna har besvarats genom intervjuer med tillverkare av prefabricerade massivträväggar, träregelväggar och betongväggar varpå energiberäkningar utförts i samband med framtagning av olika väggkonstruktioner för att få fram tre lika energieffektiva väggar.
Microstrip Solutions for Innovative Microwave Feed Systems
This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.
Faktorer som underbygger och motverkar användningen av doping : En genomgång och analys av dopingforskningen 2004-2009
Business across the Internet has increased in recent years and most companies that are selling trips have increased their sales online. Many companies that are selling trips strive for customers to receive and experience a personal service online. The meeting between the client and a webpage service system on the Internet should work. Service encounters are an essential part of the contact between customer and company and play a big part in how the first impression is perceived by the customer. To understand how a service encounter works, meeting face to face, companies need to understand how customers perceive that meeting.
Markvärdets förändring efter askspridning till skogsmark i Götaland
Askåterföringen på fastmark syftar till att återställa den långsiktiga näringsbalansen och motverka markförsurningen. Den är ett led i ett kretsloppstänkande där allt som tas ifrån marken också ska återföras.Ett ökat behov av skogsbiobränslen leder till att grenar och toppar (GROT) i allt högre utsträckning flyttas från skogen därmed förflyttas en stor del av viktiga näringsämnen. Baskatjonerna som annars motverkar markförsurningen blir kvar i askan.Askan som blir kvar efter förbränning läggs vanligen på deponi, men med hjälp av införda deponiskatter är målsättningen att askan ska återföras till skogen för att sluta kretsloppet.För markvärdesberäkningarna användes värderingsprogrammet Plan33. 12 trädslagsrena fiktiva bestånd skapades, 6 fastmarksbestånd och 6 bestånd på dikad torvmark, med medianboniteter för Götaland.Tillväxteffekterna har visat sig vara måttliga på fastmark. Denna studie visar att endast granmarker ger positivt nuvärde vid askåterföring i Götaland.
Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
