Kvalitetsarbete i grotskotning
This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.
Individanpassningens ytterligheter : Några betygsmässigt hög- respektive lågpresterande gymnasieelevers åsikter kring engelskundervisningens utformning.
In today?s society there is a discussion regarding students? level of knowledge and personalisation. The classrooms consist of heterogenic groups of students with different learning needs and levels of knowledge. The purpose of the present study is to find out how the students who participated perceive the teaching of English as an additional language with regards to personalisation, and how they believe differentiation can help develop and deepen their learning. This study has been conducted using a qualitative method with interviews as the core, complemented by observations. The results have been analysed and interpreted hermeneutically. The results show that those students who have a positive attitude to English education, irrespective of their grade, are those who see the benefit of knowing English outside the classroom, and thereby create a connection between reality and studying English.
Fuktrelaterade risker vid lågenergikonstruktion i lättbetong : En studie av ett nyproducerat passivhus
Trenden i byggbranschen är att efterfrågan på täta, energisnåla byggnader ökar. Passivhus och andra lågenergikonstruktioner blir vanligare och vanligare. Riskerna med att bygga in organiskt material som trä i dessa konstruktioner har fått branschen att börja titta på alternativa material. Lättbetong är ett material som både har bärande och isolerande egenskaper. Dessutom är det inte organiskt vilket gör det okänsligt för mikrobiell påväxt.
Cash-to-cash-styrning : ett spelteoretiskt angreppssätt

Scientific method: The study uses a qualitative and a quantitative method, where primary data is collected from semi-structured interviews. Additional primary data is collected from an unstructured interview with an expert in the field of which is examined. Additional data has been collected from the studied companies? annual reports.Theoretical references: The primary theory has been Game theory, where the researchers have used this theory to analyze the behaviors of the companies.
Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation
Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.
Restenos efter PC1 (ballongvidgning i hjärtats kranskärl): Upplevelser ur ett patientperspektiv
Background: The intention of this study was to clarify the patients perspective of what it means to suffer fiom documented restenosis after one or more Percutaneous Coronary Intervention (PCI). Aim: The aim of this qualitative study was to ascertain the patients experience of restenosis. Method: Nine patients were interviewed. They had undergone at least one PC1 and two had also undergone Coronary Arterio Bypass Grafting (CABG). Data collection and analysis were done simultaneously according to Grounded Theory methodology and were continued until new interviews provided no additional information, i.e saturation was met.
Kombinationsverksamhet - flera verksamheter inom ett lantbruksföretag
In today's Sweden there are approximately 23 000 combination companies, and most of them have a connection with the agricultural sector. The most common type of additional operation is some form of contracting.The aim for this degree project is to answer the following question: which problems and key factors exists within combination operations? The main topic will be within coordination and management questions within agricultural companies with an additional operation.Litterateur written earlier within this subject will be used in this thesis. Mainly litterateur which contains information about combination companies and diversification of some sort. There are also other theories used in this thesis such as; resource based theory and decision making theory in order to understand the problems and key factors within combination companies.In order to investigate the aim of this thesis we have chosen to perform two qualitative interviews with the managers of two different combination companies.
XRF-analys av förorenad mark : undersökning av felkällor och lämplig provbearbetning
X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to affect the results of measurements.The purpose of this thesis is to bring a deeper understanding of how different factors affect the results of XRF-analysis. A large number of measurements have been made with the instruments Niton XLt 700 and Niton Xli 700. Results from measurements of lead, zinc and copper have been analysed.This study has shown that a greater moisture content will give a lower measured concentration for the same sample.

Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :
It is important for today?s farmers to minimize the costs for crop establishment, because
of decreased prices and support from the EU. Farmers, who plow in autumn on heavy
clay soil, often do some kind of tillage in autumn to get better soil structure before
spring seeding. This is especially important when growing small seed crop, e.g. sugar
beet and oil plants.
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.
Majstorkning :
The corn plant came to Europe with Christopher Columbus in the 14th century and have
ever since bin cropped here, but corn haven?t bin very common in Scandinavia until
recently. The mainly use for this crop silage but even corn for grain is cropped in
Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden
corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen
Sverige is the biggest buyer of corn at the moment.
Organisationskultur och informationssökning. En fallstudie av internkommunikationen på ett folkbibliotek
This thesis aims to identify bottlenecks in the internal communication of aSwedish public library. Specifically, it addresses the behaviour of the library staff when they seekfor work-oriented information through interaction with their colleagues. A fundamental assumptionof this study is that the information-seeking process depends on organisational culture. I have madean exploratory case study in a medium-sized Swedish public library, where relevant issues areidentified and correlated with the culture of the organisation.I have used Schein's three-level model to describe the culture of the library; this model definesculture as a set of basic assumptions and the actions of people as expressions of their culture. Datafor the study were gathered using several approaches, including interviews with the library staff andobservations of them.
Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna
Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties.
The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.
