Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Framtida inhemska proteinfodermedel i den ekologiska fjädefäproduktionen :

Organic layers and broilers will according to (EEG) no 2092/91 be fed 100 % organic feeds in year 2012, which is expected to present problems associated with the specific protein requirements of poultry. This document aims at describing the feedstuffs that possibly may constitute a part of the solution to these problems. Peas, field beans, naked oats, canola, hempseed and sunflower come out as interesting feedstuffs. Biproducts from the milling and dairy industry together with marine protein supplements may be brought to the fore, provided that the demand for organic products will rise further..

Bosättning, agrarkris och fäbodväsende : vegetations- och markanvändningshistoria i Läde, Dalarna

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

På vandring genom historien - en undersökning av hur förr och natur är kultur

Nature and culture are often described as opposites, but at the same time nature is often de-scribed as culture and past. This essay examines how nature and the past are culture. I study how 51 people make shifting distinctions between nature and the past in relation to culture, the present and the future. By using the concept of Orientation of Sarah Ahmed I analyze how the informants direct themselves against nature, past and culture through a questionnaire, ob-servations and walk-alongs. I discuss how their ideas about nature and the past differ with their different starting points and are shaped through their physical meetings with them.

Kravmärkt? : en studie om gymnasieelevers uppfattningar om krav och förväntningar i deras studiesituation

The purpose of this study is to investigate and describe the variation in perceptions of demands and expectations of study performance among a group of students at an upper secondary school. The study is inspired by a phenomenographic approach in which variations in perceptions of a phenomenon are of importance. Twelve students at a science program participated and were interviewed in groups of four. The results show that among the students there are several different perceptions of the demands and expectations to perform they felt present in their lives. The most important result is that it is the students' own demands and expectations on their performance and study results that are seen as the most demanding..

Kommunikation från organisation till målgrupp : En undersökning om en NGOs kommunikationsarbete i Tanzania

In this study I have examined how narrative techniques can be used to promote the reading value and readability in information. My focus has been on the communication-agency Mandoly?s information-brochure which function is to inform other companies about their own potential for development in collaboration with Mandoly. The purpose with this study is to examine how it is possible to increase the reading value in order to engage the target group. In my study I have used four methods: analysis of Mandoly?s old information-brochure, literature studies, a qualitative interview, and an user test.

Framtida användningsområden för materialadderande tillverkning : En studie i hur materialadderande tillverkning kan användas i rymden

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..

The pig as an animal model for type 1 Diabetes Mellitus ? with focus on carbohydrate and fat metabolism

Diabetes mellitus is an endocrine disorder affecting a range of different mammals, including dogs, cats, horses and humans. Worldwide, 347 million people have diabetes, and the disease is an increasing burden on the world?s poorest countries.

Listeriosis, which is caused by Listeria monocytogenes, is a rare food borne disease that primarily affects people whose immune system is weakened. These may be elderly people, pregnant women, new-born infants and individuals on immunosuppressive medication. The most common symptoms are meningitis, septikemia and abortion. The mortality is high, on average 20-30 %. In recent years the number of cases in Sweden has increased.

Effektivisering av produktionsflöde : Införande av ny teststrategi

Ericsson AB in Katrineholm is a part of the Section Business Unit Network in the Ericsson Group. The plant's main task is to produce printed circuit boards in small volumes with a high product mix and focus on delivery and cost effectiveness. At the factory they produce printed circuit boards in the Module department.The Module department has for a long time had a high output of non-approved circuit boards in their production. This has led to a growing stock of non-approved circuit boards on the company?s repair department.The purpose of this thesis is to investigate how Ericsson in Katrineholm can increase the outflow of approved articles in their test process in the Module department.

Historiebruk och historiemedvetande i Venezuelas Förenade Socialistiska Partis Libro Rojo

This thesis examines the use of history, historical narratives and the relation to Venezuelan historical consciousness in Libro Rojo, a publication of The Unified Socialist Party of Venezuela (PSUV). It consists of four parts: an introduction, a declaration of principles, statutes and finally what is called the programmatical bases (bases programaticas) of the party.A starting point for this thesis is that this is an under prioritized area of research about the Bolivarian revolution in Venezuela. It aims to show the centrality of history in these fundamental documents of the biggest left-wing party in Latin America.The thesis finds that symbolically charged historical figures ? mainly national icons of Venezuela´s struggle for national liberation - are mobilized to back up contemporary aspirations and influence public perception of what kind of future is possible and desirable. Libro Rojo structures the relationship between past, present and future in order to influence historical consciousness.It also finds that Libro Rojo constructs a vision of socialism which aims to show that the ideas and actions of Venezuela´s symbolically charged historical figures are compatible with the ideas of 19th and 20th century western Marxism.

Oharmoniserad familjerätt i EU : Problematik och lämpliga förändringar ur medborgarnas perspektiv

The EU guarantees the free movement of persons. The citizens of the EU Member States have the right to move freely without barriers within the EU borders and this result in an integration of the peoples in Europe. The integration result in several international family relationships. It is not unusual in the present situation that families have international relations. For example, spouses in a married couple may have different nationality.

DET HÄR ÄR OCKSÅ GRAFISK DESIGN - Ett bidrag till diskussionen om ornamentik, funktionalism och kvinnors marginalisering.

This thesis examines the relationship between the marginalization of ornamentation during functionalist modernism and the effect it had on female graphic design practice. By examining the historiography from a gender and feminist theory of history I present a different way of interpreting, not only the history of graphic design but also the concept of graphic design. This thesis does not reach a conclusive result, instead it sets the foundation for further research and illustrates the opportunities that we as graphic designers have to benefit contemporary graphic design by critically reviewing and redefining our history through a diverse historiography..

Filter och kapsling för IR-givare

This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.
