Markberedning i blockrik terräng : en jämförelse mellan grävmaskin och harv

Runt 70 % av skogsföryngringen i Sverige utförs genom plantering efter maskinell markberedning. På de flesta marker uppnås tillräckligt antal godkända planteringspunkter men vid riklig förekomst av block som hindrar eller stör markberedningsaggregatet blir det problem. En annan komplikation i samband med markberedning på blockrik mark är att där till följd av tidigare brukningshistorik och ålder ofta finns rikligt med död ved i form av lågor. Vid markberedning ska hänsyn tas till att dessa inte skadas, eftersom död ved är viktig för den biologiska mångfalden. Huvudsyftet med denna studie var att jämföra resultatet av markberedning med grävmaskin respektive harv på blockrik mark, vad gäller planteringspunkter och skador på lågor. Även användbara planteringspunkter innan utförd markberedning samt skador på lågor orsakade av maskiner i samband med avverkningen studerades.

Planering av lägerområden : exemplet Sjöröd

This is a final thesis on the landscape architecture program at the Swedish University of Agricultural Sciences. It is the end of five years of studies and comprises 30 ECTS. This thesis is about the camp area Sjöröd, located by Gyllebosjön (the Gyllebo Lake) on Österlen in Skåne, southern Sweden. The thesis results in plan for how the area could be used in the future. It also raises the questions; what scouting of today is, how it is to be developed for the future, what a camp is and which aims the scout movement has set up for itself and its activities. The thesis also treats what is typical for Skåne, for Österlen and for the area around Sjöröd as a starting point.

"Din gud är fejk, dra åt helvete!" : Om elevers syn på religionskunskapsämnet och dess inverkan på förståelse och tolerans

This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.

Jämförelse mellan en träbro och en betongbro : En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

Barnens bibliotek : Barn och bibliotekarier tipsar om böcker på Internet

The aim of this two years master?s thesis in library and information science is to study how children and librarians recommend books through the website Barnens bibliotek. In the scope of this aim it also tries to answer the following questions: What qualities in books do children and librarians respectively emphasize when they write book recommendations? How do they formulate the recommendations? And finally, how do their respective recommendations differ?To examine these aspects a total of 50 book recommendations were chosen and analysed through an hermeneutic approach. Out of these 50, 30 were written by children and 20 were written by librarians.

Pellets - en framtidsmarknad?

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Geografisk prioritering av CTI-utrustad virkestransportkapacitet

Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

Det goda hemmet och det ideala barnet : Svenska fosterhem för finska barn i Sverige genom Hjälpkommittén för Finlands barn i Uppsala län 1941-1949

Syftet med denna uppsats är att analysera mansbilden av karaktären Edward i filmen Edward Scissorhands (Tim Burton, 1990). Genom attstudera hans personlighet och egenskaper ur olika perspektiv, som kan uppfattas som både manligt och kvinnligt, har jag försökt att ta reda på vem denna utstickande karaktär är.Med hjälp av genusteorier och jämförelser av tidigare filmatiseringar som Ed Wood (Tim Burton, 1994), Sleepy Hollow (Tim Burton, 1999) och The cabinet of Dr. Caligari (Robert Weine, 1920) har jag även kunnat fördjupa mig i mansbilden av Edward. Jag har dessutom fokuserat kring Tim Burtons säregna filmskapande, men också kring stjärnskapet hos Johnny Depp, skådespelaren som Burton ofta samarbetar med.Edward Scissorhands har visat sig vara en man med både manliga och kvinnliga attribut, vilket gör honom till en icke stereotypisk man som saknar hjältemod och en muskulös kropp. Trots det så tyder inget på att han är mindre man bara för att han har mer eller mindre egenskaper som generellt uppfattas som manliga.

Regler i förskolan : En studie om förskollärares och barns tankar

This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.

En kartläggning av kompetenskraven på Sport managers

The purpose of this study is to survey which competences and personal qualities the labour market, for students with examination from the Coaching and Sport management education at Vaxjo University, require.

Miljöhänsyn vid offentlig upphandling :

One of the biggest challenges in the human history is to prevent environmental pollution. Everybody has an indirect or direct influence on the environment through his or her consumption. The stakeholders are not just interested in price and quality, they are also interested in the circumstances of production and how this affects the environment. By taking environmental concern in public procurement it is possible to speed up the environmental adjustment of services and products. Environmental awareness has become more and more self evident in the environmental work.

Ett barnanpassat boende

This degree project is an inquiry in how plan layouts and functions should be designed to suit families with children. The project aim to, if possible, find good solutions and designed houses that satisfy the requirements a family have.Last spring we contacted Willa Nordic AB, a company that produce houses, and they had a suggestion to investigate living for families with children. Their motif were that they lacked in information and knowledge in how to design houses that correspond to a family's needs. We thought the idea was exiting and motivating.The autumn 2008 studies were made on earlier published reports, in the subject "living environment", to get a solid background. The earlier inquiries shows a clear development through the whole 1900's, from being without standards to have well defined norms.

Utvärdering av en ny selektionsmetod för hingstsperma : med avseende på membranintegriteten och membranstabiliteten

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Pedagogiska datorspel - Designandet av en teoretisk applikationsmodell för pedagogiska spel ämnade för gymnasieskolan, med elevperspektivet i fokus.

In this work we?ve been focusing on how to adjust educational computer games in order to make them suited for the educational context of upper secondary school. Our opinion and entrance to the study is that the related developers of the subject, in some ways, have failed to successfully combine and find the balance between the entertaining and pedagogical aspects in the games. Our main questions is which aspects in the games game developers need to take in consideration to satisfy the pupils, but also what qualities that is needed for them to function in their educational context. In order to do that we had to investigate the people of the target groups own perspective on what technological and social aspects in the computer games they assess as important.

Stabilisering av insektsangripna möbler : en jämförande studie av konsolidanter

Denna rapport är en jämförande studie av utvalda konsolidanter som används till att stabilisera nedbrutet insektsangripet trä. Av de trägnagande skadeinsekter vi har i Sverige är det främst den strimmiga trägnagaren som är intressant i möbelsammanhang. I rapporten beskrivs den strimmiga trägnagaren, en liten skadeinsekt som kan åstadkomma stor skada om den får verka ostörd. Insekten finns utspridd i hela Europa och är ett stort problem då den angriper alla typer av träslag. Nedbrutet insektsangripet trä förlorar sin styrka och kan behöva konsolideras genom att injicera konsolidanter in i träet.
