Potential för energiklippdrivare i Skåne : markägarintresse, råvarutillgång & ekonomi

As the Swedish governments long term goals include a reduction of fossil fuel dependency, increasing pressure is placed upon energy companies to create and develop new solutions for renewable energy. The following case study was done in collaboration with the company Sydved Energileveranser AB and one of their contractors, Enarssons Skogsentreprenad AB. The objective of the study is to examine the bioenergy situation in region of Skåne and evaluate the potential solutions in the region for a forest-fuel assortment, based on a bioenergy-cutting-system. As a part of this study I have compared ordinary manual cuttings done with a chain saw and cuttings made using the new ?bio- energy cutting system?. The cuttings made under both systems were tested in areas near agricultural fields or pasture land in order to maintain an open landscape.

Att förhandla om rum : en etnologisk analys av hantverkares tal om kundmöten

The aim of this study is to point out variations of practices in the relationship between professionals of service occupations and their clients. The material consists of four openly conducted thematic interviews with male professionals who work in the environment of their clients' homes.The main theoretical approach of this analysisis undertaken with ethnicity in mind.The practices identified aim to throw light on the boundaries between the differing cultures of professionals and their clients.The analytical termsboundary reduction and boundary maintenanceare used in this research.The two-stage analysis points out different practicesused, in chronological order, during contact between professionals and their clients. This is followed by a statement of the themes which connect, primarily fromthe professional perspective. The results indicate an intimate connection between intercultural and transcultural aspects through the use of cultural transparancy, which is a strategy connecting different roles, aswell as use of loophole tacticsthat afford the possibility of definingspace, place and relationship.It's illustrated how the professionals operate from "within the structures and worldview" of the client, and this analysis also reveals a glimpse of the potential for cultural changein the meeting between different cultures..

I BRÄNNPUNKTEN: Samhällsekonomisk utvärdering av arbetsmarknadsåtgärder. Illustrerad med hjälp av Brännpunkt i Kävlinge 2002-2005

The purpose of this essay is to examine cost-benefit-analysis as a method of evaluation of labour market policy. To illustrate the possibilities and difficulties of the method chapter four contains a partial cost-benefit-analysis of the results of a labour market project in Kävlinge. The questions this essay strives to answer are the following: What possibilities and difficulties do cost-benefit-analyses entail? How would one conduct a cost-benefit-analysis of the project in Kävlinge?The method used in this essay is mainly a literature study of cost-benefit-analysis of labour market programs. The labour market project Brännpunkt is used as an example in a partial cost-benefit-analysis.The applied cost-benefit-analysis of the Brännpunkt project in Kävlinge shows that it is possible to calculate the profit for the society as a whole, given that the necessary information is obtainable.

Öronakupunktur mot ångest och depression : En analys av behandling i grupp

Introduction: Anxiety and depression are common among patients enrolled in psychiatric outpatient care. Ear Acupuncture is an alternative form of treatment that has been shown to relieve anxiety and depression in previous studies.Aim: To evaluate ear acupuncture as a group treatment for depression and anxietyMethod: A psychiatric outpatient clinic has been offering group treatments with ear acupuncture for anxiety and depression for 5 weeks. Participants of the study have answered self-rating scales Montgomery Åsberg Depression Rating Scale, Beck Anxiety Inventory and Sheehan Disability scale before and after the treatment period. Material was collected in the period 2008-2012 and has been analyzed in SPSS.Results: Data from 31 patients were included in the study. The results from the study showed a significant difference, between the measurements before and after treatment, with a reduction of the average values in the three different scales.Summary: From this study, it is difficult to draw any conclusions about the effect of ear acupuncture.

Optimala reduktionsgränser för kalldragna rör : Optimal reduction limits for cold-drawn tubes

Dragbänken installerades på avdelning kallbearbetade rör på Ovako i Hofors 1990. Sedan dess har kvalitetskraven på de dragna rören ökat. Samtidigt har produktivitetskraven ökat, det vill säga att tillverka rör till rätt kostnad. I produktionsplaneringsprogrammet finns gränser och regler för hur de dragna rören ska tillverkas för att rätt kvalitet och kostnad ska uppnås. Eftersom både de dragna rören och de varmvalsade ingångsrören har ändrats med åren så stämmer inte alltid gränserna och reglerna idag.

The aim of this study was to examine if parents, of children diagnosed with ADHD, exprerienced any changes regarding their childrens appetite after starting psycostimulant treatment. Further more the aim was to examine what kind of changes concerning the appetite that were found and if they affected the meal situation as a whole.Method: A questionnaire study was conducted in the spring of 2011. The study included 81 parent?s to children who were enrolled at the Habilitation in Uppsala and medicated with psychostimulants for ADHD. The children's ages ranged between six and 18 years.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

Energieffektivitet Hos Dubbelskalsfasader

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

Telekomspecialisering i Östra Europa - Integrationens betydelse för en produktionsfragmenterad industri

One of the most distinguishing features of contemporary globalisation is production fragmentation, a splitting up of the manufacturing of a good into several different stages. Production fragmentation creates new opportunities through vertical specialization; a country incapable of mastering the entire production process may specialize in the manufacturing of one separate part. The aim of this thesis is to examine to what extent international integration affects a country?s ability to engage in vertical specialization in an industry characterized by production fragmentation. The analysis focuses on the european integration process over the last decade, where countries in eastern Europe with relatively low labour costs have been integrated with more capital abundant western economies.

Lärare med hörselproblem samt deras sätt att hantera detta - en intervjustudie

Denna rapport var en kvalitativ empirisk intervjustudie där fyra lärare deltog som alla hade någon form av hörselproblematik. Syftet var att undersöka hur lärare med hörselskador upplever buller i den egna arbetsmiljön. Vidare var syftet att undersöka lärarnas sätt att hantera den problematik som hörselskadan medför i deras arbetsmiljö. Informanterna utsattes för, i deras mening, höga ljudnivåer mellan 1-4 timmar per arbetsdag. När det gällde hur hörselproblemen påverkade dem i deras yrkesutövande upplevde lärarna att det medförde det vissa positiva effekter, då genom en ökad disciplin bland eleverna samt minskade ljudnivåer i klassrummet.

CSR och B2B, olja och vatten? : En undersökning av CSR som konkurrensfördel inom Business-to-Businessmarknaden

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

Den demokratiska lyxen

Abstract: The fashion industry is perhaps the most unpredictable one where change occurs very rapidly. In order to be attractive and interesting in this competitive industry, a brand must constantly be up to date and differentiated from other brands to attract the consumers. This has given rise to an increasing growth of brands that cooperate for marketing reasons and more specifically, clothing retailers that perform designer collaborations with exclusive designers to create limited collections.Studies describing the effects of those collaborations on the retailers brands are rare and especially from a consumer perspective. Since H&M has been a pioneer in designer collaborations and has done it more times and for more years than any other retailer we have conducted our study on their case. Our intention was to investigate how the designer collaborations have affected the brand equity and image of H&M, if the collaborations have increased the willingness to pay for H&M's other ranges and if they have affected H&M's ability to extend its brand to higher price segments, through an experimental study.

Ställtidsreduktion i montering av kopplingar

VBG Produkter AB is a process-orientated company that develops, manufactures and markets trailer couplings with belonging coupling equipment, protection equipment against skidding and stands for wagon-bridge for heavy vehicles. The company feels that their set-up time in production for couplings is not at an acceptable level. Due to high demands of customer oriented production the intermediate stock level of included products within the assembly of couplings has gradually increased which has resulted in high inventory holding costs. VBG Produkter applies Kanban in their production, therefore it is important to produce exactly the necessary amount and avoid overproduction. The objective of this project is to suggest appropriate solutions so that VBG Produkter is able to reduce their set-up time in assembly of couplings, by identifying internal and external set-up time for the chosen process bushing cell.
