Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

I ett försök av mig att ge spelmediet samma sorts behandling som många andra medier före det har jag valt ut fyra spel inom två olika genrer för en analys av deras handling, karaktärer, estetik och gameplay. Handlingen summeras enligt reglerna för narrativt berättande och en semiotisk infallsvinkel används sedan för att leta efter saker, tecken, som är värda att tas upp för analys i alla fyra kategorierna. Vissa jämförelser görs mellan spelen, främst inom kategorierna estetik och gameplay, först inom samma genre och sedan genrerna emellan för hitta likheter och skillnader i sättet spelutvecklarna har valt att utmana spelaren och göra spelen roliga att spela och hur de har valt att förmedla spelens handling. De utvalda spelen är Capcoms Devil May Cry 3: Dante?s Awakening, Sony Computer Entertainment Americas God of War, Konamis Metal Gear Solid 2: Sons of Liberty och Ubisofts Splinter Cell: Chaos Theory.

This study examines how management consulting firms work with business- and functional strategy and how these strategies are interrelated. More specifically we focus on business strategy (business unit level) and knowledge strategy (functional level) and whether these are aligned or not, i.e. whether strategic congruence exists.A number of recent studies have examined the importance of business strategy and knowledge strategy in management consulting firms separately, but few have pointed out the importance of the alignment between them. With this study we contribute to the strategic field of research with a model that describes how management consulting firms should work with their knowledge strategy given their business strategy. The model is developed through a synthesis between theories in the field of strategic congruence, business- and functional strategies and thereafter tested by an empirical case study of six management consulting firms.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse. This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.

The purpose of this work was to investigate and provide understanding regarding how AI can be used to make organizations more efficient, where risk management is also discussed. The basic model for the study is the Resource-based view, which is about making use of one's resources which are described through many different perspectives. The method used for this study was a qualitative analysis, which was applied through interviews with several people with high positions within companies and relevant skills, based on insight and experiential knowledge.These people work in different industries, therefore a large part of the work was intended to carry out a comparative analysis between a line of different businesses. The results showed that AI is in a developing phase, and based on the respective industry, it has developed in different ways. Finally, it turned out that AI can make businesses more efficient by, among other things, managing data and automating various work processes faster compared to humans.

The survey aims to highlight and describe how the schools' teaching strategies look like in the work of pupils from the neuropsychiatric disability AD/HD (Attention Deficit / Hyperactivity Disorder). The pedagogical strategies have been investigated in an integrated and segregated teaching method. The study is qualitative in nature where the interviews conducted, first with a student who has been diagnosed AD/HD but also with teachers from each school who is well versed in student teaching and work. The results of the study show that knowledge and commitment about AD/HD is crucial to students' role and function in school. If knowledge and commitment is sufficient for the student teaching tailored to student needs and the risk of misunderstandings occur decreases. Security is a key factor for students who have been diagnosed AD/HD and learning form in itself is no guarantee that students will feel safe. Students have in the two teaching methods stressed that they feel safe at school and with their education and therefore has no teaching method preferred.

BVC-sjuksköterskan möter många föräldrar som har frågor om kostintroduktion till spädbarn, en av BVC- sjuksköterskans uppgifter är att undervisa föräldrar i kostfrågor. Studier har visat att föräldrar upplever att de får olika råd från BVC-sjuksköterskor, vilket kan göra föräldrarna osäkra på vilka råd de ska följa. Syftet med pilotstudien var att beskriva BVC-sjuksköterskans erfarenheter av att ge kostråd till föräldrar vid introduktion av fast föda till spädbarn. Fyra intervjuer genomfördes med BVC-sjuksköterskor inom barnhälsovården i Region Halland. Kvalitativ innehållsanalys användes som analysmetod.

In recent years, employees at large companies have started to demand that their employer should work more for good causes. The money the company wants to donate to charity is distributed mostly through a vote to decide where the money will be remitted. The purpose of this design case is to develop a design concept for a web-based donation service that involves all employees at a company. Furthermore, the authors of this study intends to explore how the motivation for employees of a company can be affected by participation in this service. In this design case, the service function, quality and concept was tested and evaluated.

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

According to the national curriculum guidelines for elementary school, preschool and after-school 2011, (i.e. Lgr11), the Swedish school is based on a democratic foundation. Schools should prepare students to develop an understanding and acceptance of cultural diversity not only in the society as a whole but also how this should be reflected in the morals and ethics between us. The purpose of this study was to describe how teachers in multicultural schools perceptions and experiences on teaching pupils with diverse immigrant origin, and how they apply these cultural expression in practice.In particular, I focus on four teachers in multicultural schools and how they reason about applying cultural expressions that are transmitted at these schools and by them. Explicitly, I review how from policy documents and their own personal pedagogic are reflected in the actual teaching.

Problem: How is management accounting change understood via the duality perspective in the field of alternative management accounting research?Purpose: The purpose of this essay is to develop a tool for analysis aspiring to provide understanding for how differences and similarities with regards to the duality perspective may have different consequences for understanding management accounting change.Contribution: This paper aspires towards a theoretical contribution through an in-depth review of existing conceptual literature. This is done to gain clarity in definitions and uses of concepts, with related terms, referring or relating to duality. Through clarifying different meanings of duality, consequences for how to understand management accounting change, and the different approaches to using a duality perspective, the tool for analysis which is developed in this essay aims to contribute to a movement of alternative management accounting research towards increased comparability as well as increased insight into how management accounting change is currently understood through this type of research.Method: Literature reviews based on Booth et al.s SALSA-framework. Creation of a tool for analysis for usage when reviewing material based on a duality perspective.Conclusions: The duality perspective differs, and affects understanding of management accounting change, in accordance with the following five themes:Theme 1: The duality perspective is affected by differences in the use of definitions/descrptions.Theme 2: The duality perspective is affected by different purposes of the agent and different credit given to the agents power/ability to alter change.Theme 3: The content of the duality perspective is affected by the existence and purpose off being inspired by different theoretical approaches.Theme 4: The duality perspective affects the idea and understanding of the form and expression/process of management accounting.Theme 5: Different duality perspectives have the ability to lead science against increased pluralism and/or synthesisIn order to increase understanding for and comparability between scientific contributions through a duality perspective there is to some extent a need for more and better definitions and a more problematizing when combining theoretical approaches.

The purpose of this essay is to examine what literary heritage teachers communicate in the school subject Swedish at upper secondary school. The overall research question for this work is: Which authors and/or works are mentioned by the teachers in the school subject Swedish at upper secondary school? How well do these authors and/or works answer towards a multicultural perspective? Which factors affect teachers´ selections of texts? Based on this purpose and these research questions, the aim is to answer the didactic question of what.To accomplish the purpose of the study a quantitative method has been used. The survey was conducted in two medium-sized cities in central Sweden, and was answered by 17 teachers. The study shows that the teachers ascribe the Western and Swedish literature great importance.
