Kommunägd skog i Sverige : en enkät- och intervjustudie av de tätortsnära skogarnas ekonomiska och sociala värde
This Masters thesis is performed at the request of the National Board of Forestry in order to investigate how the Swedish municipalities use their forests. The study is of general character with emphasis on the social values of the forests.
The municipalities? purposes with their forests have varied over time, but lately the social aspects have been recognised as interesting. The social values of the forests can be defined as the values from the forests that contribute to the wealth of humans. This has socio-economic importance for the municipalities.
The study was performed as a quantitative questionnaire survey, complemented with qualitative interviews.
Designkoncept av ?toycam? : Framtagning av koncept för analog kamera
Analogue photography is something that many thought died out in the beginning of the 21?st century as a result of the digital revolution. But that?s not the case. As the digital revolution swept over the world a movement of analogue cameras, and so called toycams grew bigger.
Husväggar av massivträ: En kostnadsjämförelse
Trä är och har sedan länge varit en av Sveriges mest exporterade råvaror. Branschen sysselsätter idag omkring 100 000 människor i landet. I samband med de senaste årens miljödiskussioner bör husens uppbyggnad diskuteras. Syftet med detta examensarbete är att främja husbyggnation i massivträ som de senaste åren fått mer publicitet inte bara på den svenska marknaden men också i centraleuropeiska länder.Frågorna i detta arbete handlar om att identifiera de vanligast förekommande ytterväggskonstruktionerna och jämföra deras materialkostnader samt kostnader för arbete vid montering. För att ha kunnat göra en rättvis jämförelse har BBR?s energikrav varit den gemensamma nämnaren för ytterväggskonstruktionerna.Frågorna har besvarats genom intervjuer med tillverkare av prefabricerade massivträväggar, träregelväggar och betongväggar varpå energiberäkningar utförts i samband med framtagning av olika väggkonstruktioner för att få fram tre lika energieffektiva väggar.

Kalkningens påverkan på fosforlöslighet : skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved
phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution.
The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

Tegel och klinker - keramiska material på mark :
Being an architect I create spaces with roof, walls and fl oor. The availability of the essential materials to create such spaces is practically unlimited. The materials also play a significant part to the character of the created space. I hope to contribute to the general understanding of materials as elements in the design of urban spaces by having intensely explored one specific material in depth, pointing out its bad and good qualities. I am of the opinion that the reason for choosing a material shouldn?t be because of a shortage of knowledge, facts or references, but what character you want for the room.
When travelling across Europe, it sometimes feels like clay paving is everywhere, but back in Sweden it is almost unseen of in modern landscape architecture.
Markvärdets förändring efter askspridning till skogsmark i Götaland
Askåterföringen på fastmark syftar till att återställa den långsiktiga näringsbalansen och motverka markförsurningen. Den är ett led i ett kretsloppstänkande där allt som tas ifrån marken också ska återföras.Ett ökat behov av skogsbiobränslen leder till att grenar och toppar (GROT) i allt högre utsträckning flyttas från skogen därmed förflyttas en stor del av viktiga näringsämnen. Baskatjonerna som annars motverkar markförsurningen blir kvar i askan.Askan som blir kvar efter förbränning läggs vanligen på deponi, men med hjälp av införda deponiskatter är målsättningen att askan ska återföras till skogen för att sluta kretsloppet.För markvärdesberäkningarna användes värderingsprogrammet Plan33. 12 trädslagsrena fiktiva bestånd skapades, 6 fastmarksbestånd och 6 bestånd på dikad torvmark, med medianboniteter för Götaland.Tillväxteffekterna har visat sig vara måttliga på fastmark. Denna studie visar att endast granmarker ger positivt nuvärde vid askåterföring i Götaland.
Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Hallmöbel för förskolor
I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Livsstil och livskvalitet året efter avslutad hjärtrehabilitering : en enkätstudie
ABSTRACTBackground: To be stricken with a cardiac infarction is among other things linked to different risk factors. Many studies show that the participants in cardiac rehabilitation programs learn to deal with the risk factors, increase their quality of life and lessen the risk for re-infarction.Objective: To describe the lifestyle and perceived quality of life of the individuals after having participated in cardiac rehabilitation program and to see if they had maintained their results up to a year after having a cardiac infarction.Method: The 19 individuals who had participated in cardiac rehabilitation in 2010 after having had a cardiac infarction were asked to participate in the study. Everyone agreed to participate. The study was made analyzing the surveys, one a locally made, that the individuals had filled out four and eight months after cardiac infarction, and the other the generic Quality of life questionnaire EQ-5D, that the individuals had filled out two and twelve months after cardiac infarction. Result: The individuals have not changed their lifestyle after having participated in cardiac rehabilitation which can be interpreted that they have followed existing recommendations. The mean weight increased with one kilogram, no depression is shown and they stress less.

Möjligheternas skog : utveckling av Teleborgsskogen som tätortsnära rekreationsskog i samarbete med närboende och aktörer
The Swedish forestry aims primarily maximize production and economical wins. However, especially urban forests have great qualities as space for recreation and children?s play, which means that other goals should lead the forests management. The Teleborg forest is a wooded area in Växjö, surrounded by urban dwellings, schools, nurseries etc. A great part of the forest was wind felled during the storm Gudrun in 2005 which changed the forest, earlier dominated by spruce, dramatically.
