Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.

The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.

The purpose of this study was to examine the narrative skill of sixyear-olds in terms of macrostructure and cohesion, and its relation tonarrative content, auditory attention, auditory short-term memory and threemeasures of word retrieval. A group comparison of macrostructure andcohesion was also performed between children with and without epilepsy.The material consisted of audio recordings of 44 children (18 with epilepsyand 26 from a reference group) retelling the story Nelli-sagan (Holmberg &Sahlén, 2000). No correlation was found between content and macrostructureor cohesion, but several between the latter two. Auditory short-termmemory and word retrieval without pictures showed several correlationswith macrostructure as well as cohesion. No differences in macrostructure orcohesion were found between the children with epilepsy and the referencegroup.

The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.

This thesis is intended to review and create a greater understanding for the history and originsof printed scraps from late eighteenth century to the beginning of the twentieth century.A questionnaire survey was sent out to several Swedish museums, containing questionsconcerning their collections, possible exhibits, special difficulties and types of damagesconcerning scraps and their current storage. A visit to the Gothenburg city museum storagewas made to take a closer look at their scrap collection and how they were stored. Thisresearch resulted in an understanding regarding the current situation of printed scraps, whichunfortunately appears to be quite poor and inattentive. These results are presented in the firstchapter.The second chapter describes the history of printed scraps, followed by a chapter presentingrelevant printing techniques and technology. This is followed by various chapters dealing withhow the printed scrap has been used through the ages, history and development of motifs andthe album's significance.

Increased resource efficiency in an energy system could result in large economic and environmental benefits. Tekniska verken i Linköping AB (Tekniska verken) is responsible for the district heating network in Linköping. Their vision is to create the world?s most resource efficient region. An important step towards this vision is more efficient usage of produced heat, something which could be achieved through integration of a seasonal heat storage in the energy system.

This degree project has been carried out by Niclas Andersson and Sebastian Zwahlen, students of the Innovation and Design Engineering Program at the Faculty of Technology and Science at Karlstad University. The project was carried out during the spring 2010 and includes 22, 5 ETCS credits.Initially the group had contact with the company Mavis möbler AB. Mavis gave the group the task of developing a new bedroom product. To assess the needs and problems of bedroom behaviors, an extensive questionnaire and several interviews were made. This became the starting point for further work.According to the results uncovered during the market research a vast problem was found with temporary clothing storage.

The thesis investigates if it is possible to replace several pumpimpellers with one controllable pumpimpeller, with a economical and a manufacturing analisys aspect. The studied pumpimpeller is mounted on a midrange wastewaterpump, N3127MT.In the thesis a contemplated manufacturing process is evaluated for a concept that are supposed to act as a controllable pumpimpeller. The pumpimpeller are studied in a manufacturing and flow matter and are presented in the thesis.The manufacturing cost is also estimated, and this has been compared to the storage cost and other costs that the existing pumpimpeller generates.The thesis also shows that the concept has minor losses in cutting quality aswell as the effiency comparing to the existing pumpimpeller.The concept also raises the manufacturing cost and this increasing cost makes the presented concept to expensive to carry through.An investigation of the costs that the existing pumpimpeller produces has also been done, and this shows that there is not that much expenses to earn regarding to for example the storage cost. The storage cost includes information from Flygt?s central storagecenter in Lindas, Sweden and Metz, France, and also an inventory about the pumpimpellers located at Flygt?s different distributors worldwide.The thesis shows that a controllable pumpimpeller will generally increase the cost for the pumpimpeller and the performance of the pumpimpeller will decrease..

Although I myself haven?t been bullied per say during my school years. I?ve sure been teased and occasionally felt left out. On the other hand ? who hasn?t? And that as well is my point.

This essay discusses my proposed collection of short stories. The aim has been to examine the texts in terms of form and thematics, and position of the texts in a social context. First I present the collection, and then look at the texts from stylistic angle. I have chosen to use the concept of descriptive style. I have picked out certain parts of my texts in order to see which effect they have on the reader (in this case I).

This study aims to examine how the interventions for homeless persons in the municipality of Kalmar are organized. The study is based on four half-structured qualitative interviews with both representatives from different instances and also from persons who have experience of being homeless.The theoretical bases we have used to analyze the material are organization theory, specifically the concept of bureaucracy. Our results show that homelessness is not seen as a problem in itself, since the general view is that homeless people often have a complex problem scenario where drug- and alcohol abuse and mental illness are common.It is often the latter that takes priority in the interventions and the housing question is therefore neglected. We also found that social services do not have a satisfactory structure around the organization of the work on homelessness. They do not have any specific device in Kalmar that focus on homelessness issues with the result that the existing units are forced to take care of the work of homelessness.

THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.
