Den ociviliserade "norrlänningen" - en studie om social kategorisering och stereotyper
In this thesis we have tried to show the problems that the categorisation of ?norrlänningar? generates. We have also tried to describe what the stereotypes of ?norrlänningar? are by examining what people say on web Logs. The method we have used to find the stereotypes in our empirical material is the discourse analyse.
Död ved och förekomsten av två mossor som indikerar skoglig kontinuitet
Studiens syfte är att undersöka arterna Buxbaumia viridis och Nowellia curvifolia för att kunna förutse var man hittar dessa signalarter. Detta gjordes genom att död liggande ved undersöktes i Ycke naturreservat samt en närliggande brukas skog, Östergötlands län.Resultaten visar att faktorerna som är avgörande för B. virids är markkontakt och nedbrytningsklass. B. viridis föredrar att växa på lågor i de högre nedbrytningsklasserna (4-7) och med stor andel markkontakt, över 80 %.
UTREDNING SAMT UTVECKLING AV ETT PLATTFORMSOBEROENDE GEOGRAFISKT INFORMATIONSSYSTEM
This thesis have been performed at Sweco Position in Jönköping. The work was split into two, where one part included an investigation regarding the possibility of developing a cross-platform GIS (geographic information system) with HTML5 and CSS3. A prototype would also be developed within this part.The second part included development of a cross-platform GIS for a client to Sweco Position. The client operates in the forest sector and had already an existing solution, with many problems. The client required an application with delimited functionality and which was not bound to a specific hardware.As the client users often were located in areas with limited Internet access, one additional requirement was that there would be some offline support.The students handle subjects within development of GIS, for example map projections, map services and mapping libraries.The application came to be developed in HTML5 and ASP.net.
Bedömning av loggbok : Bedömning av loggbok med en uppgiftsspecifik matris
The purpose of my independent work was to develop and test a task-specific assessment matrix to the students writing Logs that occurs in connection with their APL (workplace-based learning). The matrix is based on upper secondary school subject plan House building from The Swedish National Agency for Education and the four courses House building process, House building 1, House building 2 and House building 3 - conversion. Due to the matrix structure, I used the example matrix of Malmö University. The task-specific assessment must both serve as a guide for students in the implementation of the log writing, and in the evaluation of the assessment work. Both students and teachers then get a common assessment tool for evaluation.
Kvalitetssäkring vid upphandling av svetsatgods
Företaget Eco-Log är ett förhållandevis litet företag som tillverkar skördare och skotare. För attkunna hålla konkurrensmässiga priser har de lagt ut svetsningen på underentreprenad och ägnarsig således endast åt konstruktion, montering och försäljning av sina maskiner. På senare tid harde upplevt att kvalitén hos ingående material hos svetsade detaljer har varierat på ettoroväckande sätt och ville således skärpa upp kvalitén till den högre nivån.Om man väljer att lägga ut svetsningen på entreprenad är det viktigt att man utför en del åtgärderför att säkerställa att man behåller den kvalitet svetsfogarna kräver. När man dessutom väljer attlägga ut tillverkning på låglöneländer är det än viktigare att tillverkningsunderlaget inte lämnarutrymme till fri tolkning som kan ge bristande kvalité som följd.Syftet med examensarbetet är att ta fram inköpsrutiner som säkerställer att man får den kvalitéman behöver, trots att tillverkningen sker externt.En provstruktur togs fram för att bedöma hur väl en underleverantör klarar att leverera ettacceptabelt resultat. Därtill vidareutvecklades en checklista med kontrollfrågor som antyder omsvetsverkstaden har den utrustning och ordning som krävs för att bedriva kvalitativ svetsning.Slutligen togs ett betygssystem fram som möjliggör att utvärdera olika underleverantörer iförhållande till varandra, baserat på Eco Logs tidigare erfarenhet av dessa leverantörer..
Dubbskador på Alvestakubb
Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.
Övervakningssystem för båtelektronik
Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Tillvaratagande av GROT i skärgårdsnära miljö :
The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications.
Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines.
In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner.
The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase.
This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of Logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed.
Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable.
Realisering av en modulär skogsmaskin - En skalmodell
Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports Logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.
Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
Clear-cut and substrate characteristics important for the occurrence of the beetle Upis ceramboides
Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides.
This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very
rare and decreasing, and Norrbotten where this study was conducted.
Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, Logs of approx.
Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin
The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive Logs.
Det gåtfulla tillståndet ? Samarbete och arbetssätt kring barn med selektiv mutism.
AbstractThis study is based on my work as a secondary school teacher of literature and the Swedish language and rooted in my interest in developing knowledge about the importance of teaching literature in order to both cultivate young people?s reading habits and their view of themselves as readers. The more concrete purpose of this study is to examine a reading project that focuses on theories of literary perception and teaching literature.I examine four pupils who, in 2003, participated in the reading project as readers and compare this description with their view of themselves as readers seven years later. I complete the study by examining how they discuss reading and the teaching of literature. The method is qualitative and the empirics include materiel collected in two different time periods: first in 2003, in a class I taught in a secondary school; and second in 2010, when I examined four of the former pupils who participated in the project from 2003.
Ny huvöppningslösning för Eco-Logs skördare : Från idé till tillverkningsunderlag
This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.
