Lodgepole pine - stability after thinning
SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.
Kan mjuka golv i grisningsboxar minska skador på klövar och ben hos smågrisar?
The incidence of damage to the claws and legs in piglets caused by the floor in farrowing pens is a widely known problem and very common in today's pig herds. Although the association between floor and damage has been known for over 35 years, no suitable solution has been found to reduce the negative impact. The purpose of this study was to make a literature study to document the experiences of the use of different types of flooring in farrowing pens and also, in an own study, examine if soft floor in farrowing crates could lead to reduced damage to the claws and legs in piglets compared to concrete floor. The study was conducted in two herds, A and B. In each herd, farrowing pens with concrete floor and concrete floor with polyurethane coating were compared.
Optimering av betong med Byggcement (CEM II) till håldäcksproduktion
This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..
Utopia Trek : utopibegreppets resa genom Star Trek
Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed.
Infektiösa ledproblem i ekologisk och konventionell grisproduktion
We live in an exciting society, characterized by continuous changes and challenges. The effects of the globalization are widespread. The continuous flow of people, capital and goods follows in the wake of advances in communications, transport and information technology, resulting in a changed situation for different stakeholders in the society. This situation leads to increased cooperation and exchange, but also increased competition. The primary means of collecting empirical data for this study was interviews and a document study.

Beskrivning och rendering av kurvade backspeglar
Driving simulators are a very important part of the research that is done at VTI. Enhancing the realism and creating a better driving experience in the simulators are very important and an ongoing work process for the engineers and researchers who work with the simulators. This project has been done as a part of this developing process and the purpose is to enhance the realism of the rear-view mirrors.Simulating realistic rear-view mirrors has been demanded, not only from the researchers at VTI, but also from car and truck manufacturers. To achieve a realistic mirror view a method to measure and parameterize real mirrors has been developed. The code for the existing graphics system has also been redone to be able to handle the new types of mirrors introduced..
Utläggningsrapportering i en mobil webbapplikation
This report describes the implementation of expense reporting in a mobile web application. Two different types of expenses could be reported: remuneration and time deviations. In addition to the creation of new expenses, existing expenses should be able to be edited or deleted. The implementation would be designed in such a way that it prevents the user from making data entry errors in an intuitive way. The bachelor?s thesis was performed for Flex Datasystem AB in their mobile web application, Flex WebApp. Due to delimitations made during the project only functionality for the expense-type remuneration was implemented..
Hydd- och huskonstruktioner från förhistorisk tid : En kronologisk översikt från stenålder till tidigmedeltid i östra Mellansverige.
This thesis is a chronological survey over the hut and house remains from the Stone Age to the Early Middle Ages in Eastern Central Sweden. The thesis also contains a test which I have conducted to see which investigation method had the best results in identifying house remains at an archaeological site. I subsequently discuss the result of this test, what it represents and also what may be done differently in order to get other types of results..
Something old, something new, something borrowed, something blue : A collaborative master thesis project exploring the development of Löfstrands Verkstad?s identity through physical artifacts, the contextualization of them and the system that provides the
Förord:Ämnet för mitt examensarbete var att arbeta med företagsidentitet genom att fläta samman ett specifikt företags (Löfstrands möbelrenoveringsverkstad) befintliga verksamhetsstruktur och ambition med planeringen och formgivningen av dess egenproducerade objekt.Löfstrands Verkstads vilja att skapa möbler som skall kunna ärvas vidare (likt de möbler de renovering i sin befintliga verksamhet) lades tillsammans med möjligheterna med småskalig produktion (i deras verkstad, samt kontaktnät) som grund till en verksamhetsbreddning för Löfstrands Verkstad i Hägersten.Den fysiskt manifesterade slutprodukten av examensarbetet är en möbelkollektion skapad för Löfstrands ideal, identitet, lager- och produktionsmöjligheter. En kollektion i vilken kunden bjuds in till medskapande (eller art directing) av möblerna för att knyta strarka band till dessa och verkstaden..
Simulering av elektriska förluster i en vindkraftpark : Utveckling av programvaran Wind Farm ElectricSystem Calculator (WFESC)
When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.
SOLPANELERS MÖJLIGHETER, EN AKTUELL RAPPORT FÖR MONTAGE PÅ FASTIGHETEN KORNHILL
This thesis deals with the possibilities of installing solar panels on a property, the building is owned by Kornhillschurch and called Kornhill. The owners of the property wanted to learn more about potentials for installation of solar panels on the property, therefore we described different types of solar cells and solar cells essential function to generate electricity in the report. Different factors that are limiting the generated energy are mentioned.An investigation of the property?s potential has been made in order to consider different designs. When sites that were considered suitable for solar cells were selected, different design options were made, one for each site.
Styrningen av den svenska förskolan
In this study we have focused on the operational management of the public pre-school in Sweden. We have studied how the governance system is designed, why it is designed this way and what impact it has on the operational management. This has been analyzed from a theory stating that there are two types of organizations: pay-driven and function-driven. Through a case and document study we came to the conclusion that the pre-school is a function-driven organization but is nowadays acting on a market and have adopted characteristics of a pay-driven organization. We connect this change to the phenomenon New Public Management.
Var man slipad förr? En experimentell undersökning av sandpapprets föregångare.
In this essay I have looked more closely at different means of grinding wood prior to the mass production and total dominance of the sandpaper in recent times as there is virtually no information to be found about this. I have also done a few replicas of how early sandpapers might have looked and as a part of creating these replicas I have also tested diffrent types of early glues. The conclusion of it all is that all the alternative grinding materials tested workd virtually as well as modern sandpaper, with some reservations. And the replicas, although rough, worked mostly well despite being constructed with simplicity in mind. This indicates that an artisan could easily construct sandpapers if he so wished..
Nürnbergsprocessen i svensk press : en studie över tre tidningars ledarsidors rapportering av rättegången i Nürnberg
One of the most well-known trials in history is the one in Nürnberg, Germany, soon after the end of World War II. It is understandable that this caused a lot of discussions and that it was a world known trial which set the standards for a lot of similar occasions later on. The aim of this research is to focus on the opinions about this trial from a perspective of well-known Swedish newspapers. The method is to analyse three big papers with different political views and to see what separated them and what maybe united them. By studying the master-pages of the newspapers a picture is given of how the contemporary time had an understanding for the trial reports, which we in our time have established as facts.
