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.
Buntning av grot med lastbilsmonterad utrustning :
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.
H?RNERVMOSSANS P?VERKAN P? LJUNGHEDENS ARTM?NGFALD: En f?ltstudie fr?n Sandsj?backas naturreservat
Campylopus introflexus is a moss species that originates from the southern hemisphere and has spread worldwide during the 20th century. Today it is classified as an invasive alien species in many countries, and it has been seen during inventories that it has become widespread in Sweden as well. The purpose of this essay is to contribute to new knowledge about how this moss affects species diversity on Calluna heathlands in Sweden. The study includes both fieldwork and an analysis of scientific literature on the subject, and the question that is answered is if C. introflexus has an impact on species richness in the heather peat.
Halltider : Eskilstunas handboll- och innebandyföreningars tillgång till 40x20 planer
For youths leisure activity the organized sport is vital. Young people become increasingly sedentaryand the healths of young people are the various municipalities responsibility. In Eskilstuna, thehandball is very popular but there are only three grounds that meet the standards of the dimensions ofa handball pitch, 40x20 meters. The same dimensions are used by floorball. Eskilstuna municipalityowns one of these, the other two is privately built and owned and the municipality rents time in thehalls.IF Guif and HK Eskil are two handballclubs in the central part of Eskilstuna.
Systematisk riskexponering i svenska hedgefonder: Svenska hedgefonders exponering mot riskfaktorerna i Fung & Hsieh (2004) under perioden 2006-2007
This paper aims to investigate the systematic risk exposure of Swedish hedge funds using a modified Fung & Hsieh (2004) asset-based style factor model. The results show that the average Swedish equity hedge fund and fund of funds had a significant positive exposure to the equity market portfolio and the spread between small cap and large cap stocks (SMB) during the sample period. This is consistent with our a priori expectations and previous international studies. We do not find the expected systematic fixed-income related risk exposure for the fixed-income hedge funds and fund of funds in the sample. The empirical material used in this study is taken from a publicly available fund database maintained by the Swedish Financial Supervisory Authority (Finansinspektionen).
Läsförmåga bland högstadieelever utan och med läs- och skrivsvårigheter
The study?s aim was to examine reading ability in secondary school students. The participants; 30 grade 7 students (13 years old) and 30 grade 8 students (14 years old) without literacy problems, and eleven grade 8 students whom either had documented literacy problems or received special education for it, were selected through convenience sample. Text comprehension was tested by three texts which are called the Skobigotexts. Three reading settings were applied: listening, silent reading and silent reading with textsupport.
Miljöutredning : ett fastställande av betydande miljöaspekter samt lagar och krav som rör Skaraterminalen Spedition AB
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Annedal ? Boendekostnader i en helt ny stadsdel och sambandet med upplevd stadskvalitet
Annedal is a brand new neighborhood in the Bromma part of Stockholm. The neighborhood construction has now reached its halfway point. When finished, 5000 people are estimated to live in Annedal. The focus for the new area is variation. Both housing co-operatives and rented apartments have been built and more are under construction.A study about the valuation of town quality in the Stockholm region was produced by the Stockholm County Council in 2011.
Kapitalstruktur i små företag : En kvantitativ och en kvalitativ studie
Background: In the current labor and business policy debate in Sweden there is a major focus on the need for it to become easier to set up small firms, and that it needs to become easier for small firms to hire staff. In order to set up and run a business, funding is required. Firms can choose to work more or less actively with this issue, but they all need to relate to it. There are basically two ways to fund a business, either through equity or through debt. The ratio between these two sources is called the firm?s capital structure.Purpose: To chart the capital structure of small firms in Sweden.

Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
Grund plöjning med Kvernelands Ecomat och Ecomat Seeder : resultat från undersökningar genomförda år 2005
The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field
studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala.
In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with
Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring
mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the
seedbed, the number of emerged plants and weeds, the pentration resistance and the yield
were examined.
Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good
alternative to conventional autumn ploughing when growing spring crops. During the season
2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after
conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm).
In the other two studies, ploughing to different depth in the autumn with the Ecomat was
compared with conventional mouldboard ploughing and stubble discing.
