En förstudie för bioetanol produktion i Borås
AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.
Personlighetsskillnader mellan gymnasielärare och blivande gymnasielärare : Differences in personality between high school teachers and future high school teachers
The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.
Fett - rekommendationer, kostvanor och konsumtion mellan 1935 och 2009
This literature research is meant to answer the following questions:
? What was the Swedes consumption of fat from 1935 to 2009?
? How has the fat consumption corresponded to the current recommendations?
? What is LCHF and which are the main advantages and disadvantages?
Fat supplies us with energy, isolates and protect organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides.
Utsikt för olja : Hur värderas oljeaktier
Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.
Samspel i staden : en studie av Shared Space ur landskapsarkitektens perspektiv
In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.
Nytt eller gammalt? ? En studie av stadsbiblioteken i Hässleholm och Kristianstad
The purpose of this essay is to examine how a newly built library and an old library from the sixties work out of an experience and feeling oriented view. Are the fundamental conditions of an old library compatible with the library standards of today? To be able to carry out this examination we have chosen two rather small Swedish libraries. One is the public library of Hässleholm, which opened in the year 2000, and the other is the public library of Kristianstad opened in 1965. The material used to attain the purpose of the study consists of literature studies and qualitative observations and interviews.
Energieffektivisering av uppvärmningssystem i småbostadshus
Uppvärmningen av ett småbostadshus står vanligen för kring hälften av dess energianvändning. Enligt energimyndigheten drar det svenska standardhuset 22,7 MWh per år varav 12,2 MWh går till uppvärmning. Att ge värmesystemet så bra förutsättningar som möjligt bör alltså vara av intresse för varje husägare, kanske främst ur ett ekonomiskt perspektiv men även ur ett ekologiskt perspektiv.I detta arbete har olika energieffektiviseringsåtgärder studerats som kan implementeras i en tvåplansvillas värmesystem bestående av en värmepump, golvvärme på nedervåningen och olika värmedistributionssystem på övervåningen. Åtgärderna har innefattat både praktiska såsom val av isolering i golvvärmesammanhang och mer teoretiska såsom reglerstrategier. Relevant teori för de ingående systemen har presenterats och utgjort grunden för implementeringar av systemen i simuleringsprogrammet IDA Indoor Climate and Energy.
Stabilitetsberäkningar och åtgärdsförslag vid islast på Skålandammen
Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.
CarEye ? Sees & Saves: Fordonskamera för skadedokumentering
In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.
The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness
In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production.
The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.
En utveckling av samverkansformen partnering. Från splittrat begrepp till gemensam modell.
At this point seamen have a lot of tasks of administrative character, beyond the traditional tasks aboard a ship. Due to the new conventions that are formed by IMO, more requirements are added which often lead to time consuming administrative tasks and documentation that should be spent on activities which are contributing to the ships safety. The issue has been observed by IMO that has through BIMCO done a study with the aim to identify and reduce administrative burdens at sea.The primary aim of this study is to find out if safety officers aboard Swedish ferries consider that SOLAS Chapter III, 8.3 och 19.5 regulations are administrative burdens, restricted to muster lists and documentation of training aboard the ship.The secondary questions to the study are if it is possible to remove, combine or change the documents and how much time can be saved by doing this. The question about timesaving could not be answered, because the values were scattered and could not be used for further investigation. The observed values were accumulated by a survey and the result indicated that safety officers did not experience the two regulations as administrative burdens.

Politikerns (o)etiska beslut -en fallstudie av Olof Johanssons avgång som miljöminister
Central in this paper is Olof Johansson, Swedish minister for the environment, there the focus lye on his resignation from this duty which occurred in 1994. This essay is a case study there I?m trying to identify which ethical reasons which lye behind his resignation. The relationship between politics and ethics is an interesting aspect to investigate and my ambition with this paper is to analyze that relationship in this specific case.The analysis has its focus built on the occurrence of role conflicts and the making of ethical decisions. Aspects like personal ethics versus organisational ethics, objective responsibility versus subjective responsibility etc.
Självförfattning, läckage och olikhet : Om att kombinera kvantitativ metod och queera teorier i sexualitetsstudier
The aim of this study is to combine queer theories with quantitative methods. In social sciences, queer theories are being widely and increasingly used. Quantitative method is also widely used, and as a traditional method it can be regarded as a cornerstone in social sciences, sociology in particular. However, the two perspectives, queer theories and quantitative method, seem at a first glance to be very different in their understanding of social phenomena. Queer theories have, with some exceptions, mainly focused on qualitative research concerning such phenomena as sexuality, while the field of science is quite diverse.
