Abstract
Considering the social dimension of sustainable development this thesis focuses on the
qualities of life and how the environmental qualities that the inhabitants value can be
incorporated in the physical planning of the municipality. The thesis deals with the problems
that occur when the physical planning, whit its focus on the environmental aspects, also
needs to consider peoples opinions, that springs from the individual experience of the
place.
The municipality of Mark, where this thesis takes its place, is characterised by the
countryside landscape. Mark is situated in the western part of Sweden close to Göteborg,
Borås and Varberg. The commuting is extensive and the demand for dwellings in the
municipality is increasing. Those who strive to live in the municipality have a conception
of what life on the countryside means and of which environmental qualities they want to
assimilate.
Pelletering av tallspån : grundläggande studier
Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity.
Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.
Borta bra men hemma billigast? : En studie av vad som påverkar socialsekreterares val av insatser i Karlskrona och Karlshamns kommun
The purpose of this essay was to investigate and analyze affecting factors concerning social workers in two different municipality social services, Karlskrona and Karlshamn, working with cases of youth drug abuse. We wanted to see what affects social workers in their choices of assessments of youth drug abusers. We wanted to find out whether the organizational aspects or the cliental qualities affect the social workers more than the other in the choices of assessments. Among the cliental qualities we used in this essay, gender was the most important quality and therefore the quality we wanted to pay special attention to. When it came to the organizational aspects we paid special attention to the social workers boundaries of agency.
Stöldskydd
To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.
Vad tycker skogsägare om virkesinköpare och inköpsorganisationer? : utveckling av ett skogsbolags tjänster och köpverksamhet till privata skogsägare
The private forest owners play a key role in the supply of round wood to the Swedish forest industry. Today it is a keen competition between forest companies about the wood from private forest owners. In order to get access to the wood from the private forestry you need to be an attractive collaboration partner, who can offer long-term collaboration, service at top-level, and acting for good prices to the forest owners.
This work aims at analysing the situation on the market today. It gives Sveaskog purchase department a good view of the forest owners? opinion in general about the existing purchase activities.
Forestry service level and timber prices are determining factors for a successful relationship between forest company and forest owner.
Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
Fukthaltsförändringar för skogsbränsle : En jämförelse av torkförloppet i grönrisskotade och brunrisskotade vältor
In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.
Variationer av klor, svavel och aska i havrekärna : odlingsfaktorernas inverkan på havrens bränsleegenskaper
The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.
Hur såg Birkas hamn ut och vilka transporter behövdes?
What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.
Vad påverkar skogsägarnas naturhänsyn vid föryngringsavverkning i region Mellannorrland? :
The objective of this thesis was to investigate what influence nature conservation measures taken at regeneration felling. Factors analysed were the forest owners´ situation and their characters, and information activities from wood-suppliers and the Regional Forest Board (RFB). The inventory was performed with a posted questionnaire followed up by telephone to forest owners and a posted questionnaire to wood-buyers.
The forest owners were grouped in three strata, depending on the quality results (D- polytax inventory) of the taken forest conservation measures, and for this investigation forest owners were sampled from the population in the tree groups. In total 73 % (41/56) of the sampled forest owners answered the questionnaire
Group A (17 answers): Good judgement
Group B (19 answers): Bad judgement
Group C (5 answers): This group was formed from the forest owners that were informed, by RFB, about nature conservation measures and culture history consideration before the regeneration cutting.
Evolution of the Dead : Stil, social funktion och realism i modern zombiefilm
InledningThe horror of the zombie movie comes from recognizing the human in the monster; the terror of the zombie movie comes from knowing there is nothing to do about it but destroy what is left; the fun comes from watching the genre continue to develop. Although zombies are technically dead, their cinematic genre is a living, breathing entity that continues to grow and evolve.Citatet taget ur Kyle Bishops artikel ?Raising the dead? öppnar upp för en intressant diskussion angående utvecklingen av zombiefilm. De flesta i en skräckfilmspublik kan på ett fåtal sekunder med säkerhet peka ut en zombie på vita duken. Även filmad i long shots och i extreme long shots kan till och med den åskådare som är relativt ny för genren känna igen zombien.
Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
AHA in northern Sweden ? a case study : conservation values of deciduous trees based on saproxylic insects
AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.
Skogsbristen i Smålands bruksskogar : en studie av träkolsförbrukning vid Storebro Bruk 1793-1850
The forest in the county of Småland has been utilised for a long time. One of the most
important forms of utilisation of wood has been charcoaling for the benefit of the iron
industry. Shortage of forest in relation to the iron industry, was discussed already in the 17th century in Sweden. The aim of this study was to analyse the purchase and consumption of charcoal at Storebro Bruk, an ironwork in Småland, during the period 1793-1850, as well as analyse the shortage of forest at the time. To determine the utilisation of the forest in the area, I have used historical sources from Storebro Bruksarkiv.
Tidsåtgång för rundvirkesmottagning på Södra Cell Mörrum
This study was made for the round wood transport company MT Transport AB. Time studies were made in order to analyze time consumption on the mill site for timber trucks delivering round wood at the Södra Cell Mörrum mill. The most interesting was to see how much of the time spent at the factory that was waiting time. In three weeks the study was going on and the drivers were clocking it themselves..
