Skogstillväxten ca 20 år efter plantering på Flakmossen : dikningens och gödslingens betydelse vid beskogning på en avslutad torvtäkt i Värmland
This study was performed in an afforestation experiment established 1982 on an abandoned peat harvesting area, Flakmossen, in the province of Värmland, SW Sweden. The experimen-tal design include planting with Scots pine (Pinus sylvestris), in combination with various drainage intensities (20, 30, and 40 m between ditches), and fertilizer doses 0, 100, and 200 g PK per seedling applied at the date of planting.
The aim of this study was to achieve more knowledge about the conditions on afforestation of peat harvesting areas, especially regarding drainage intensity and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial.
The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter distances between ditches than 40 m can not be recommended.
When no fertilization was carried out seedling survival was very low, and the growth of sur-vived seedlings was poor. The largest diameter and height growth were observed in the areas where the highest dose of phosphorus and potassium (200g/seedling) was given.
Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :
The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking.
Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.
Samband mellan utbildningnivå och grad av konformitet till traditionella maskulina normer
AbstractTitle: Correlation between the levels of education and conformity to traditional masculine normsAuthors: Larsson, M., & Ljungqvist, D. (2008)Objective: This study is an attempt to explain correlations between the levels of education and conformity to traditional masculine norms. It is mainly based on the social construction of gender. Background: A high level of education is associated with a healthy living, and a high conformity to traditional masculine norms associated with harmful health behaviours. The background also presents different views of masculinity, the construction of gender and the construction of norms.
Diagnos av ansvarstagande : En Studie av accountability inom DN och UNT:s medicinjournalistik.
AbstractTitel: Diagnosing accountability, a study of accountability of UNT and DN?s medical journalism ( Diagnos av ansvarstagande, en studie av accountability inom DN och UNT:s medicinjournalistik)Number of pages: 45 (59 including enclosures)Author: Alexandra JohanssonTutor: Göran SvenssonCourse: Media and Communication studies C Period: Fall 2008 University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: To evaluate the quality of medical journalism in DN and UNT according to the theories of accountability and responsibility in the media.Material/Methods: The materials and methods used in this thesis are 14 articles from DN and 14 articles from UNT that have been analyzed according to the criterion set forth by Media Doctors, an Australian media accountability system.Main Results: The results showed that DN scored an average of 57% ?satisfactory? and UNT scored an average of 52% ?satisfactory? of Media Doctors rating scale. Strengths were an educational tone and an insightful review of the newest findings in the scientific community. Weaknesses were poor transparency and a tendency to neglect full disclosure of the scientific findings and sources.

Styrketillväxt med hjälp av vibrationsplatta
Abstract 1.The purpose of this study was to investigate the effects whole body vibrations on maximal strength, power output and neuromuscular activity in m. pectoralis major during bench press.Participants consisted of 35 male and 9 female military high school students (m=23, 1 years). On the basis of initial maximal performances in bench press the participants was divided into two experiments groups and one control group. Intervention groups performed a specifically designed push up program on a vibrating plate respectively a step board during 12 weeks Initial load at 60 % of 1 RM showed an average of 46, 5 kg. All groups showed an average increase of 13 kg for each person after 12 weeks.
Gallringsprioritering av contortabestånd :
Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin.
The study included 32 stands containing at least 70 % Pinus contorta.
Naturhänsyn vid föryngringsavverkningar : En jämförelse mellan certifierade och o-certifierade hyggen
A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.
Har en goodwillnedskrivning någon effekt på aktieavkastningen? : En eventstudie av bolagen på Stockholmsbörsen
On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.
Höjdförändringar på Lomonosovfonna, Svalbard, 1996-2012
The climate changes and the global warming have a great impact on the Arctic environments. This partially depends on that the albedo is getting lower when snow and ice is melting and exposes more and more dark surfaces of the land and sea. This leads to a feedback effect; the melting accelerates because dark surfaces attract more sun radiation. Because of the heating the glaciers in Arctic retreat. The purpose of this report is to obtain an eventual change in elevation on the glacier Lomonosovfonna that is located on Svalbard by comparing elevation data collected by NASA and GPS data from 1996-2012.
Bilateral deficit vid excentrisk och koncentrisk muskelaktion : En jämförande studie mellan den summerade unilaterala och bilaterala kraftutvecklingen hos roddare visavi sprinters
AimThe main aim of the study was to investigate the difference in bilateral deficit between rowers and sprinters during maximal eccentric/concentric muscle actions.? Are there any significant differences in bilateral deficit between rowers and sprinters?? Do the amount of years in practice effect the bilateral deficit?MethodFourteen male subject participants divided in 2 equal sized groups (7 individuals in each group; rowers and sprinters) performed maximal unilateral/bilateral eccentric and concentric muscle actions in a leg press machine at a velocity of 0.2m/s. The range of motion in the knee joint was 70° ? 140°. Dependent t-tests have been performed within each group pre and post test.
Renens fejskador på tall- och contortaplanteringar inom Malå samebys höst- och vinterbetesområden :
The effects of Reindeer mechanical damages on the planted regeneration of Pinus sylvestris
and Pinus contorta.
Semi-domesticated reindeer can damage young trees. In late winter reindeer rub their antlers against young trees. The aim of this study was to quantify those damages. This study covered planted objects from three different areas in northeastern Sweden.
Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL
This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.
Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält
Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.
Movement patterns of Eurasian lynx (Lynx lynx) around their kills in southern Sweden
During the last ten- fifteen years the Eurasian lynx (Lynx lynx) population in southern Sweden has increased considerably. This area has a high density of both people and roads and have a higher roe deer (main prey of lynx) density than the rest of the country. Movement patterns such as how long animals utilize their kills and how far they travel from their kills between revisits is unknown for lynx in southern Sweden. The aim of this study was to examine how different factors affected the time lynx used their kills and the distances they travelled from the kill between revisits. The data was prepared and calculated using ArcGIS and the study is based on 98 ungulate kills and 12 lynx individuals.
Förälder är lika med mamma: Synen på föräldraskap hos professionella som möter missbrukare.
Despite the fact that men dominate substance abuse research and that most programs to target substance abuse therefore are developed by and for men, very little is known about the fact that substance abusing men can also be parents. Mothers are up until today regarded as the most important parent even though society is changing and fathers are taken a more active part in childrearing. The average father today still spends significantly less time with his children than the average mother does and marginalised drug abusing fathers often disappear from their families altogether. The goal and purpose of this paper has been that through a qualitative analyses of written sources and qualitative interviews with healthcare professionals and social workers recognise how marginalised drug abusing fathers interests of taking part in their children's lives are met by healthcare, treatment and child protection agencies and how we can understand marginalised fathering as an extension of how we view ordinary fathering. I wanted to examine if there are any specific actions taken in involving these men as fathers and how we can understand their situation.
