Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

Småbarnslitteratur sedd ur ett genusperspektiv

The purpose of this Masters thesis is to investigate if gender stereotypes are mediated to children between 0-3 years through books suitable for their age. This thesis concerns books that are available in public libraries. The content will be analysed by using a combination of methods, both content analysis of all the books in our study and a qualitative analysis of a smaller number of these books. With inspiration from both Robert Connell and Yvonne Hirdman and their theories of gender and gender stereotypes, this material was read and we wanted to examine if books for very young children might establish stereotypes. Our analysis showed that many known stereotypes are common in these books.

MKB för vindkraft : En granskning av fyra miljökonsekvensbeskrivningar

Today's unsustainable resource use is influenced by many factors. One key factor isproduction methods and patterns. Trough change of production patterns enterprises can bepart of the solution to a more sustainable society. This case study has analyzed environmentalperformance of the printer company Edita Västra Aros Ltd (EVA), who has gained awards forits environmental work, and what driving forces they have had during this work. The survey isbased on a qualitative method and the collected data consists of documents and staffinterviews, which have been analyzed with content analysis.

Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

Montazami-lockar möter masterminds i Svenskt Näringslivs entreprenörsporträtt : En kvalitativ fallstudie av entreprenörsporträtt i tidskriften Entreprenör

This study has as its purpose to reveal whether female and male entrepreneurs are offered the same kind of conditions in their role of entrepreneurs in their respective media representation. This is studied by analyzing portrayals in the magazine Entreprenör (Br.E. ?Entrepreneur?). Methodologically the analysis will be making use of textual analysis, semiotics and discourse analysis in order to expose the underlying gender perspective(s) in Entreprenör.The entrepreneur portrayals? texts and visuals will be studied in the light of gender and entrepreneur theory, and more specifically on the basis of theories about representation, discourse and stereotypes.The main conclusion of the study is that female and male entrepreneurs are not offered the same conditions in their roles of entrepreneurs in a medium such as Entreprenör.

Ändring av befintligt ridhus : Gävle Fältrittklubb

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

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.

??då hör inte jag hemma hos er!? : - Att ta avstånd från en religiös gemenskap

This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.

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.

Bells helvete. En konstruktivistisk analys av helvetesbilden i Rob Bells 'Love Wins'

This paper is an analysis of the hell theme in Rob Bell's book Love Wins. A Book About Heaven, Hell and the Fate of Every Person Who Ever Lived. Using a constructivist text analysis the essay examines how Bell creates a theology around the image of hell that he advocates. The study aims to analyze and explain how Bell constructs the meaning he advocates in the concept of hell. This includes an analysis of the passages in the book that discusses what the term hell refers to and the passages that deal with properties of hell.

Att vara eller inte vara en vara : Om tips och råd i det coachade arbetslivet

This study is a critical discourse analysis on the genre of career coaching. Focus lies on questions such as how doescareer coaching articles construct the working subject, and how is working life described in the genre. The categoryof social relations is central to the study. I ask questions about which social relations are of importance, and whichare not, in the career coaching version of working life and how can these relations be interpreted from a critical pointof view. The concepts of power-knowledge is central to the analysis of social relations and the term employabilityconstitute the main theoretical understanding of what distinguish the contemporary labour market.

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.

CAP KC3-12 : Design and finite element analysis

In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.

Normföljare eller normbrytare? En studie av mangaserien Ranma ½ ur ett genusperspektiv

The aim of this Master?s thesis is to examine how Ranma ½, one of the most popular Japanese Manga series, reflects the gender system in society. We have chosen to make use of two different gender theorists to determine if Ranma ½ follows the gender norms of society or not. The theoretical framework is based primarily on Yvonne Hirdman's theory of the two basic principles: the principle of dichotomy and the principle of hierarchy. Judith Butler's theory of performative gender is used as a complement.
