Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia
There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.
Ajuourhållning av ungskogsdata med hjälp av digitala flygbilder :
The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. ?Updating? in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning.
The study also includes how the aerial photo material and experience of the interpreter can influence the quality of the interpreted variables.
The aerial photo interpretations were made by both experienced and inexperienced interpreters.
Dietary fibre composition and sensory analysis of heat treated wheat and rye bran
When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values.
The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).
Kraftspelsanalys av transportstag : Prefabricerade väggelement i betong
A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.
Pedagogiska miljöer : Barns och pedagogers uppfattningar om den pedagogiska miljöns erbjudande utifrån ett genusperspektiv
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.
Aktiv miljöverksamhet? : en komparativ studie av kommuners miljöverksamhet
Active environmental activity?? a comparative study of the municipalities environmental activityThesis in Political Science D-Level at Karlstad University byJenny Ljung Spring 2008Tutor: Michelle MichelletiThe threat against our climate is one of our biggest challenges today. The awareness of the problem has grown rapidly for the last years in governments on international, national and regional level. The Swedish government is recognized as one of the leading countries in the climate and environmental work internationally. The Swedish municipalities play a big role in this successful work.
Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil
Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

Konsekvensanalys av dammbrott vid Tjärnviksdalen
This report consists of an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map where the water level has been raised to the level that the County Board of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .
Okej vi bor tillsammans och ska klara det, men nu vill jag göra något annat : en studie i den svenska relationskomiken
Swedish films are often based on the genres romance and comedy. The films dealing with relations and comedy can almost be seen as a genre of its own. The composition of the complex relation between the audience and the genre is the primary research focus of this thesis. With the teoretical ground in intertextuality, sociology and romances the thesis examines three relations in three different films. The films english titles are, Adam & Eva, Making Babies, and Double Shift.
Det är kämpigt att vara arbetslös.
This composition is an qualitative study about unemployment and working life. The point of the study has been to make a larger understanding how unemployment can perceive by the individual and how this person can see and plan for future working life. This has been study with help from 8 intervirws. The paticipants has been umeployed between 6 months and 5 years, and they have workt arleast 5 year before the unemployment.The study has show that it is many different components who contribute to how the individual perceive the time in unemployment and how the planning for the future looks like. The persons who has been intervirws perceive their psycal health as god,, even but unemployment. The study has even show that all the persons in the study want to come out from the unemployment.
Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen
The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.
Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
Torvmarkernas utveckling i östra Uppland
This report is about a couple of specially chosen peatlands in eastern Uppland, Sweden. It concerns their development between the year 1922 and 2012. The historic fact originates from a large investigation of peatlands in the south of Sweden made by the Swedish Geological Survey, SGU, in the 1920?s. To be able to choose peatlands an analysis in GIS were made, in which we were able to find locations good enough for our field investigation. During the field investigation we bore to find nice peat cores that later went through several analyses in a lab.
