Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd

The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.

Tonala skillnader mellan en traditionell och en modern gitarrkonstruktion : En jämförelse mellan två klassiska gitarrer

During my studies to become a guitar builder at Carl Malmsten CTD, I have found an interest in the construction of the classical guitar. I am fascinated by the simplicity of its construction. A simplicity that becomes more complex when you start to study it in detail.In my final thesis I will not try to explain this complexity. The subject is to investigate two different principles regarding its construction. I would like to find out if the sayings concerning one of the principles will yield a guitar with greater ability to produce volume and projection.At a close distance the difference between the guitar?s volumes is not to speak of, but a significant difference can be seen regarding one of the guitars ability to project its sound.

Skogsbränsledrivare i klen förstagallring med contorta

The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

The intention was to determine the possibilities and limits with the online communication between the school counsellor and the pupils. The study was based on qualitative semi-structured interviews with one school counsellor and five pupils and document analysis of three descriptions of the school counsellor?s profession. The theory that has been used in this study is the communication theory: Shannon and Weaver?s Model of Communication and non-verbal communication.

Undersökning av avfallshantering i Stockholms innerstad

According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.

Projektledning för kreativitet : En fallstudie om hur projektledare skapar förutsättningar för kreativitet i ett distansbaserat datorspelsutvecklingsprojekt

Companies and projects often face the challenge of creating something new to increase their competitiveness. In this process of creating something new creativity is an important factor. By using a creative approach and utilizing creative processes new innovations emerges. An industry that has grown in recent years is the computer games industry. Competition is fierce and for the companies to succeed, the product need that extra something to make it stand out among all the produced games.The project manager's role in the creative process and the ability to be creative within a distance based company is not something highlighted by previous research.

Stjälkröksvamp (Tulostoma brumale) : stora eller små individer?

The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.

Katalog vs Nätbutik ? en studie om produktpresentation av modevaror inom distanshandeln

The survey Distanshandeln idag 2005, made by the Swedish postal service, tells us that web shops started to pop up in the 1990´s and began competing with the catalogue sells in the end of the decade. Ten years ago, it was said that the web shops would take over the distance trade market. Today we know that did not happen. Internet shopping accounted for 4, 2 % of all distance shopping in Sweden last year. Our inquiry is guided by the observation that the catalogue is still in use and moreover, it seems to have changed very little from when we were kids.

Närsalter och bottenlevande organismer i Mönsteråsviken

The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

Marknadsföring som konkurrenskraft under julhandeln : En studie av köpcentrum i Stockholmsområdet

Shopping is one of the most important social activities today and the majority of all shopping takes place in Shopping Centres. The number of Shopping Centres has increased and it is important to attract visitors by using the right marketing strategy. Christmas is an extra important period because the turnover normally increases three times in December compared to a ?normal? month. The purpose of this study is to analyze the marketing of Shopping Centres during the Christmas period, and analyze how this marketing contributes to the visitors? choice of Shopping Centre. This is a positivistic study that combines a quantitative and a qualitative method.This study concludes that range of stores and distance are the most important factors when a visitor decides which Shopping Centre to visit. During Christmas it is important to create a Christmas feeling, preferably made by offering decorations and music.

Stubbtransporter och bränslekvalitet hos stubbved :

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

Påverkar polariserande solglasögon avståndsbedömningen?

Syfte: Denna undersökning utreder om polariserande Suncovers skulle kunna påverka djupseendet.Metod: Mätningarna genomfördes på tre meters avstånd med en modifierad variant av Frisby Davis Distance Stereotest och med jämförande mätningar mellan bruna Suncovers från Polaroid, gråa Suncovers från Polaroid och utan solskydd. Undersökningarna gjordes på 36 frivilliga försökspersoner som alla hade samsyn och inte mer visusskillnad mellan ögonen än 0,1 med en synskärpa över 0,9 Snellen-visus.Resultat: Utan solglasögon var medelvärdet på stereoseendet för försökspersonerna 16,0´´ ± 10,7´´. Med polariserande Suncovers blev det en försämring, denna försämring var 2,8´´ med gråa Suncovers (p = 0,08) och 5,4´´ med bruna Suncovers (p = 0,02).Slutsats: Med de bruna Suncovers fanns en signifikant försämring i jämförelse med utan Suncovers även om skillnaden var liten. Att det är en större påverkan med bruna Suncovers än med gråa kan möjligtvis bero på att de bruna till skillnad mot de gråa absorberar våglängderna ojämnt över det synliga spektrumet..

Hur har Schengensamarbetet påverkat främlingsfientligheten i Europas länder? : En studie av sambandet mellan främlingsfientlighet och Schengensamarbetets institutionella förändringar.

The xenophobic attitudes in Europe are stronger than even. Never before have the member states had as many right-wing parties in action. The aim with this report is therefore to consider whether the Schengen cooperation has had an influence on the development of xenophobia in the member states of EU. The Schengen cooperation became a part of the European Union in 1997, with the aim to abolish the internal border controls for citizens and strengthen the external boarders towards non-members. The intention is furthermore to investigate whether the distance to Schengen ?s external boarder has an impact on the xenophobic attitudes.Three countries are compared: Italy, Netherlands and the United Kingdom.
