Handel med utsläppsrätter - hur företagsstrategier påverkas :
Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997.
The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.
Verkan på befintliga servitut vid fastighetsbildning : En studie av lagstiftningen och den praktiska tillämpningen
Syftet med denna uppsatts är att utreda hur befintliga servitut påverkas vid fastighetsbildning? vad som gäller enligt svenskt regelverk och hur det tillämpas praktiskt. Fastighetsbildning innebär förändring av fastigheter, genom antingen nybildning eller ombildning. Ett servitut är en begränsad rättighet som är belägen på en fastighet, som belastas av rättigheten, och som får nyttjas av en annan fastighet, som har förmån av rättigheten. I samband med fastighetsbildning kan befintliga servitut komma att påverkas på olika sätt.De metoder som använts är: (1) en litteraturgranskning där den svenska lagstiftningen studeras; (2) en fallstudie där utförda förrättningar studerats om huruvida befintliga servitut påverkats vid fastighetsbildning och (3) en intervjustudie med yrkesverksamma förrättningslantmätare som arbetar på Lantmäteriet.Undersökt litteratur visar att Jordabalken och Fastighetsbildningslagen reglerar hur befintliga servitut påverkas vid fastighetsbildning.
En undersökning om typografins betydelse för läsbarhet av ord i rörelse
The purpose of this work was to determine how important a word?s setting was for the readability of typography in motion. Facts regarding how reading works and the importance of the words formation for the readability were used to form a computer test. This test was performed by 15 test persons and the results were analyzed. The results show that the serif was easier to read than the sanserif.
Klimatkompensering - En bra strategi för miljömedvetna företag eller ett enkelt sätt att köpa sig ett rent samvete?
På senare år har en ny trend inom miljöarbetet uppstått. Istället för att bara vara miljövänliga tar vissa företag och organisationer det hela ett steg längre och klimatkompenserar för de utsläpp de har. Företag som klimatkompenserar hävdar att de gör allt de kan för att först och främst minska de direkta utsläpp som de förorsakar. Som en sista åtgärd, för att ytterligare minska företagets påverkan på miljön, kompenserar företagen för sina utsläpp genom att delta i något miljöfrämjande projekt. De bakomliggande motiven till att klimatkompensera är främst ett starkt miljöengagemang inom företaget sedan tidigare.
Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten
In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.
Viking Future Centre : Vision om en identitetsbyggnad i Göteborg
This thesis project is a vision of an identity building in Gothenburg, situated on the pier called Bananpiren. The purpose of the project is to create interest and stimulate discussions around the place and the building.In order to gain inspiration of what such a place can contain and express, a number of similar projects have been analysed, for example the Sydney Opera and the Yokohama International Port Terminal.A number of suggestions was then created and analysed, all of which are presented in chronological order in order to show the rejections and the developed designs that resulted in the final formation to proceed with.The result was finalised in a number of presentation images of the project that can be used by Cullbergs Arkitektkontor AB when presenting the project..
Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Kvävestatus och risk för nitrifikation i två avverkade skogsområden i Halland
Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.
Transporter på väg - En studie över Sveriges lastbilscentralers metoder för att möta ökande drivmedelspriser
Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.
En studie av den gestaltande handlingen : att förstå upplevelsen av en egen gestaltningsidé

Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling
Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
Sex on the table. The formation of a wide-ranging sex education
There is a settled stereotype for women and men which give them different possibilities in our society. The schools, which are one of the most important sources of knowledge, have a great possibility to influence. This is the reason why we are interested in how the schools are working with a project, which we will call X henceforth. What was the purpose with the project and what does it contain? What is missing in the former education, since the project was started? Are there any obstacles or prerequisite in the design of the project or in the school teaching on the basis of X? We have done interviews in the gathering of empirical material to find out all the answers to our questions.
