Föryngring i stormfälld rekreationsskog : en jämförelse mellan föryngring i produktions-, rekreation/produktion och rekreationsskog.

When the storm Gudrun hit Sweden on the 8th and 9th of January, many recreational forests in southern Sweden blew down. For this reason there is a demand for new regeneration methods as to how these storm-felled areas should be regenerated and with what species. In this study the forest is divided into three areas: production, recreation/production and recreation. The first area is a forest with production as main goal and these kinds of forests are located a bit from the city. The second type ? recreation/production forest ? has two equal goals: production and recreation, and is located close to the city.

GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :

Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments. Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.

Käppalaverkets nuvarande och framtida rötningskapacitet : en studie i labskala

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.

Från alger till biodiesel - Den italienska drömmen?

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012

This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.

Goat production in Laos and the potential of using Erythrina variegata as a feedstuff

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

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.

Volymsrapportering vid drivningsarbete

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Att skapa nya rum : Roomservice - en annan form av marknadsföring

Due to the technical development the enterprises of today are forced to creative thinking when it comes to marketing of their products. An example of one of these new methods are the development of product placement which has come to an interesting turn namely advertiser funded programming (AFP). Instead of the product just being a small part of the storyline it has become the story itself. The purpose of this study is to analyse how the advertiser funded tv-production Roomservice, a Swedish home styling program, communicates with it?s viewers as well as how they perceive the message.

En ny kvinna eller en dubbel slavinna : En studie om arbetarkvinnan under mellankrigstiden ur ett kommunistiskt perspektiv

This essay is about the Swedish working woman in the early 1930s. The empirical data consists mainly of Arbetarkvinnornas Tidning (AKT), a Swedish Communist magazine which was launched in December 1929. A qualitative discourse method has been used. Texts, articles, letters to the editor and reports about social conditions in Sweden and Soviet during the years 1929-1932 has been examined. Soviet women models and ideal types are compared with the image of the Swedish working woman.

Assessing attachment models using the implicit association test

Internal working models of attachment are claimed to be unconscious structures operating outside the conscious awareness. Existing measures of attachment are almost exclusively explicit, either self-reports or interviews and it is questionable whether these instruments are able to tap into unconscious attachment attitudes. The main purpose of the present study is to develop Implicit Association Test (IAT) tools for assessing adult attachment and to examine their construct validity. Two sets of implicit attachment measures, based on the two-dimensional attachment model (Bartholomew & Horowitz, 1991), were developed. Convergent validity was assessed by examining (1) the relationship between implicit model of self and implicit self-esteem and (2) the relationship between the implicit model of other and implicit sociability.

Hållbar köttproduktion och köttkonsumtion i Dalarna

The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.
