Att köra eller inte köra : En studie av miljömedvetna bilisters dissonansreducerande- och identitetsupprätthållande strategier
Att köra eller inte köra is a qualitative study aiming to show how environmentally conscious people who utilizes cars deal with their dissonant behavior, but at the sametime maintain an identity as environmentally conscious. The study is based on the fact that a third of those who drive cars in the municipality of Växjö would like to decrease their use of cars while at the same time having the infrastructural conditions to utilize other means of transportation. The study investigates inner obstacles in the form of habits and lifestyle, but also the different strategies the motorists use to reduce their cognitive dissonance and maintain a green identity. The indicators show that the reason the majority of the motorists continue to utilize cars is part due to inner obstacles (it's adeeply rooted habit, but also a big part of their lifestyles), part due to that the individuals have defenses for their use of their cars, defenses designed to have a dissonance reducing effect. The indicators also show that the motorists value their family higher than the environment, and in this way they can legitimize many of their car uses.
SAMMANS?TTNING AV MAKROALGER I SVENSKA ?LGR?S?NGAR eDNA sp?rning och klimatf?r?ndringar
The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the
distribution of filamentous algae as well as the general species composition of macroalgae
and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking
these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been
on linking these changes to climate change factors such as eutrophication, temperature
increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows
and their ecosystem services, such as a carbon sink and biodiversity support.
The results show that filamentous algae have increased markedly in coverage in Swedish
coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered
environmental conditions favor these fast-growing species. Genetic tracking using eDNA
demonstrated that there are functional primers for many species, particularly among brown
algae and red algae, whereas green algae require more specific primers due to greater genetic
variation.
Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning
Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.
Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall
In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.
Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk
The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.
Plusenergi och dess installationer : Kvarter Trettondagen
The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.
Vargaslätten, ett trädgårdshistoriskt arbete, fokus 1989 - 2009
Vargaslätten is a 15 hectare large privet garden in Halland in the south-west of Sweden.In the beginning of the 1990s Gunnar O.Westerberg, the owner of Vargaslätten,commissioned a work from the young landscapearchitect, Rolf Efvergren, to writeVargaslätten ? tillägnad naturen. It was a discribing work of the current status of the gardenand the summer-house of Vargaslätten. Vargaslätten ? tillägnad naturen was acomprehensive work with a detalied inventory of all the plants, the buildings, the descriptionof the surroundings and the history.
An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector
The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.
Inkludering kontra utanförskap inom Idrott & hälsa : En kvalitativ studie gällande hur elever med funktionsnedsättning upplever ämnet
The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Ronningsgift
This thesis examines the sheep shed called Ronningsgift, and its historical functions and geographical
location. The study aims to make a comprehensive gathering of the existing knowledge and to shed
light on new theories about the history of Ronningsgift. This is done through desk research including
literature and archive search, as well as an investigation and description of the construction and
materials, and an interview. Further, I got the opportunity to take part of the results of two C14
samples from Ronningsgift.
The literature and archive search shows that the most common theory of the historical function is as a
guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.
Effekter av fysisk aktivitet på recept
En litteraturstudie om effekter av fysisk aktivitet på recept av Anneli Björk-Andersson och Jenny Bylund, Institutionen för hälsovetenskap Luleå tekniska universitet. Tanken med studien var att ta reda på effekterna av fysisk aktivitet, hur man arbetar med fysisk aktivitet på recept i Norrbotten samt hur det ser ut i övriga landet. En litteratursökning som innefattade 45 artiklar, rapporter och uppsatser samt fem olika läns landstings webbsidor genomfördes. Några av landstingen har kommit långt i sitt arbete med fysisk aktivitet på recept och eftersom det var lättast att hitta material om dessa valdes de ut. Resultatet var tydligt, man har mycket att vinna på att vara fysiskt aktiv.
CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet
During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.
Optimering av realtids-PCR för identifiering och kvantifiering av Humant T-lymfotropt virus
Human T-lymfotropt virus (HTLV) är ett C-typ onkovirus som tillhör familjen Retroviridae som huvudsakligen angriper T-lymfocyter och orsakar leukemi och andra autoimmuna sjukdomar. I den nuvarande kliniska diagnostiken används Enzyme-linked immunosorbent assay och ibland vid screeningsmetoden uppträder ospecifika reaktioner. På senare tid har flera metoder baserade på real-tids PCR utvecklats för att bestämma halten av virala genom i patienter. Syftet med denna studie var att sätta upp och optimera en realtids-PCR för detektion av humant T-lymfotropt virus typ-1 och 2. Inför optimering av realtids-PCR extraherades DNA från MT-4 och MO-T cellinjer. Under optimering av realtids-PCR användes SYBR Green och smältpunktsanalys där flera komponenter bl.a.
Vem köper KlimatEl och varför? : Kvantitativ undersökning av Kalmar Energis elhandelskunder
Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.
