Increased growth in Norway spruce (Picea abies (L.) Karst.) through small annual additions of nitrogen (N) fertilizer

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Holdningskampen 1940 - 1942 och dess fortsättning : Med betoning på  kyrkans roll som sammanhållande faktor under ockupationen av Norge

During the period of occupation of Norway between the years 1940-1945 the National Lutheran Church took the responsibility of supporting the Norweigans in their ideological battle against the Nazis. This was a period named Holdningskampen in Norwegian history. One person to remember was Eivind Berggrav, bishop in Oslo diocese. He was the one responsible for the theological document of importance Kirkens Grunn that became important as a document against the Nazis and the small percentage of Christians that related to the naziinspired-church. Berggrav was also one of the founders of Den Midlertidlige Kirkeledelsen, the organisation responsible for the non-nazified churches.

Master thesis for Mechanical engineering, at the University of Lund. Incorporated in project Pondora.The purpose of this master thesis is to compare the existing one way packaging system with a proposed return crate system not yet available in Sweden. The comparison is focused on packaging handling in the grocery store.The purpose is also to investigate how operating return crate systems in Norway and Finland function, identify, the problems they have encountered and survey economic and technical aspects. The knowledge we hereby have acquired was subjectively evaluated in the thesis.The Swedish survey has a focus on meat and bread. The surveys in Finland and Norway contain all the products utilizing the studied return crate systems.We have surveyed how the handling of transport packages for meat & provision and bread is done in the store.

Plantering av barrplantor på hösten : överlevnad och tillväxt

Detta arbeta har utförts för att undersöka hur höstplantering av täckrotsodlad gran (Picea abies) och tall (Pinus sylvestris) överlever och utvecklas jämfört med vårplanterad. Detta i ett led för att se om man kan utöka planteringssäsongen för att få en jämnare arbetsbelastning över säsongen både i plantskolorna och ute i fält. Man har undersökt hur en planteringstidpunkt på sensommaren och hösten påverkar granplantors överlevnad jämfört med plantering på våren. Studien är utförd som en survey studie i södra Sverige på täckrotsplantor av gran som planterats på medelboniteter 2007-2009 och inventerats 2010. Höst och vårplanterade granplantor är jämförda parvis med samma planttyp, ålder, proveniens och geografiskt område.

Norge - finansieringen av den åldrande befolkningen

As most developed countries Norway has an ageing population meaning that the number of pensioners is predicted to grow rapidly over the coming years. As a consequence the Norwegian pension system will not be able to provide for these future pensioners. Meanwhile, a rising number of early retirees and disability pension claimants is diminishing the real retirement age. Also the individual pension amount is growing while the pension system itself reaches maturity. In short, major reforms are needed in the Norwegian pension system.

Biomassauttag vid delkvistat sortiment i klen gallring

The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect. Trees were harvested and divided into bunches based on diameter.

Elementkoncentrationer i gran utmed en markfuktighetsgradient :

One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.

Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Föryngringsplan för en svårt stormskadad fastighet i Kronobergs län :

In January 2005 large forest areas in south Sweden were severely damaged by storm. This final thesis describes the work with creating an ecological and landscape-adapted regeneration plan for a severely storm damaged property in Kronobergs region in south Sweden. This regeneration plan, in difference to more regular plans, are focusing more on the owner?s use and goal?s for the property and seeing the property from a more comprehensive view in the regeneration process. Beside production and environmental values the plan also take in consideration other values as aesthetic, culture history, landscape picture and recreation values.

Utveckling av en diameterklassmodell för grandominerade bestånd i Sverige :

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

"Heja Sverige! Heia Norge!" : En kritisk diskursanalys av nationalism inom svensk och norsk sportjournalistik med fokus på bevakningen av Skid-VM i Falun 2015

The purpose of this essay, entitled ?Heja Sverige! Heia Norge?, was to study the difference in nationalistic tendencies between Swedish and Norwegian news coverage of the 2015 FIS Nordic World Ski Championships in Falun, Sweden, which took place between 18 February and 1 March 2015. It was the fourth time the event took place in Falun, previous games having been held in 1954, 1974 and 1993.I performed a critical discourse analysis of a total of twelve articles split over two race days ? one where Swedish athletes outperformed Norwegian athletes and vice versa. I did this order to study if the news coverage in each of the two countries? most promininent sports papers; Sportbladet in Sweden and VG Sport in Norway, was charaterized by a nationalistic discourse, as well as comparing the two to find similarities and differences between them.Having based my analysis on theories and previous research regarding media events, nationalism, national identities, ?us and them?, imagined communities et cetera, I came to the conclusion that a nationalistic discourse is, without a doubt, present in the news coverage ? something very unique for sports journalism as a genre.

Nationalbibliografin: en komparativ studie över musikområdet i Norges, Sveriges och Danmarks nationalbibliografier.

The national bibliography is an important tool in information retrieval. Bibliographies as lists of books have existed for centuries, but the national bibliography as we refer to it today, as a directory of the total national imprint, has only existed for about 50 years. The object of this thesis is to investigate music documents in Scandinavian national bibliographies. The method I have used for this investigation is a comparative study of the music departments in the national bibliographies in Norway, Sweden and Denmark. The investigation is performed by answering the following questions: How do Norway, Sweden and Denmark live up to IFLAs Guidelines and recommendations for the national bibliography? Can one discern any differences between the three countries in this area? The documents in focus are sheet music and phonograms.

Rotpostvolym = stämplingslängd?

This work was conducted during spring and summer 2012 together with the company Uppsala Academy of Management as the principal. The two main objectives for the work are that: ? Make a comparison between the measured volume in the standing forest and the measured volume at the industry on Uppsala Academy of Managements actual stumpage sale volume to see how well it conforms. ? Examine if the buyers see any particular advantages or disadvantages of actual stumpage sale volume and what they think of Uppsala Academy of Managements actual stumpage sale volume and structure in general. I chose to use actual stumpage sale volume from the tree years 2009, 2010 and 2011 in my work. I divided the actual stumpage sale volume following four categories which was pine, spruce, pine/spruce and seed trees. After that I picked out sixteen actual stumpage sale volumes from each category to be a part of the work.

Fotröta hos får : en kartläggning av hur olika länder hanterar sjukdomen

Foot rot is a severe claw disease which occurs among sheep and goats in most parts of the world, with outbreaks in hot and humid weather. It is a contagious bacterial infection caused by Dichelobacter nodosus in association with Fusobacterium necrophorum. Foot rot has a negative impact on both animal welfare and economy.This thesis presents how Australia, Nepal, Norway, Switzerland, Great Britain, Sweden and Uruguay handle foot rot. In the selection of countries the focus was on countries that have control- or eradication programs against foot rot. There are differences in the climate, animal husbandry practices, animal welfare and economic resources in the countries that are presented.

Körskador i gallring : en studie av 21 drabbade objekt i södra Sverige

To guarantee the customers a job satisfactory executed Sydved has been certified by the ISO 14001 standard. One part of the certification is the standards of soil damages. The soil damages were over represented during 1999 and 2000. It was therefore a need to study the problem in order to see what could be done to reduces these damages. A filed study was carried out on 21 subjectively selected stands from the following five districts: Vänersborg, Falköping, Borås, Jönköping and Åseda. As the study is a descriptive study of the soil damages, their character and extension, only stands were tracks were reported were considered.
