Teknik för vårskörd av hampa till stråbränsle :

Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops. The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.

Realisering av en modulär skogsmaskin - En skalmodell

Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.

Kvarteret Flaggskepparen, Industriellt byggande för offentligt ägda bostäder -En fallstudie i samarbete med NCC Komponent och MKB

The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

Effektivisera materialflödet med hjälp av självgående truckar

The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

Hållfasthetssortering av plankor med hjälp av röntgendata

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

Biblioteksplanen ? skrivbordsprodukt eller effektivt styrdokument. En intervjuundersökning om inställningen till den kommunala biblioteksplanen vid några grundskolor i Malmö

The aim of this Master?s thesis is to examine how the introducing of municipal library plans has influenced some compulsory schools in Malmö. I wanted to know if the library plan is a possible way to improve the quality of the school library. Through qualitative interviews with four school librarians and four headmasters, I investigate their knowledge of the library plan and their opinion of the possibilities to realize the directions of the plan. The theoretical framework is based on a model of organizational culture by Bakka, Fivelsdal and Lindkvist.

Svenska Lantchips : Och deras internationaliseringsprocess

Svenska Lantchips is a Swedish SME sized snack manufacturer. Being a small, medium sized, family-owned business with branches throughout the world, they make an interesting company for a case study. The case study I have conducted focuses on the internationalisation process of this family owned company ? how they, despite their size, find ways to keep up an unique business structure, designed for internationalisation.The aim of this essay is to compare Svenska Lantchips? internationalisation process with traditional internationalisation theories and see if these are compatible with this company. The theories used are The Uppsala Model, The Network Model, and The Born Global Theory, with The Born Global Theory representing the younger generation of models.After undertaking an in-depth interview with Michael Hansen, business developer at Svenska Lantchips, I collated a substantial amount of material, which I have used as the basis of this essay.

Vad är ett E-Arkiv? : En fallstudie på E-Arkiv Stockholm

The aim of this thesis in Archival Science was to explore the concept of electronic archives and the challenges that might be encountered when attempting to move archives into a new digital age, as well as having a closer look at the term e-archive itself. Another aim was to explore how the OAIS reference model works in practice.To explore these questions I decided to do a case study on E-Arkiv Stockholm, a functioning e-archive. I decided to do a study on several documents that were created throughout the project, these included documents related to the planning of the archive, as well as the final report. My reason for this method was that these docu-ments came straight from reality and would give a clear and unbiased view of the project and it?s many aspects.Examination of the documents showed that the OAIS reference model and its concepts had been the foun-dation of much of the planning.

MEMS baserad referensoscillator

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

?Om inte vi mammor mår bra mår inte barnen bra heller? : En studie om kvinnor som har barn med frihetsberövade män

The purpose of the essay is to analyze the welfare state from a gender perspective. Further, the paper analyzes and critically examines three different normative solutions provided by Irish Marion Young, Nancy Fraser and Jürgen Habermas for the realization of a welfare state that includes women.Habermas argues that the welfare state has created a situation of dependency and state paternalism which reduces both individual and collective self-determination. Young follows Habermas? argument. She argues for a political climate where justice is reduced to the distribution of material goods rather than the elimination of underlying relations of domination and gender specific patterns.

Establishing in China?s ?good-enough? market - - A benchmarking study on Scandinavian engineering industries? further establishment in China

Title: Establishing in China?s ?good-enough? market - A benchmarking study on Scandinavian engineering industries? further establishment in China. Problem discussion: The Chinese market is gaining importance for Scandinavian engineering industries and is by many considered a crucial market to be successful in. These companies have a tradition of producing premium products for premium customers. However, in China many are currently experiencing the threat from local competitors producing products of somewhat less quality aimed at the vast Chinese middle market - the good-enough market.

Vilka makroekonomiska faktorer styr köp av kapitalvaror? : en teoretisk och empirisk studie av faktorer som påverkar hushållens val av nybilsinköp.

I detta projektarbete kommer följande att behandlas;Efter en definition och begreppsförklarande inledande del presenteras en teoretisk genomgång av konsumtionsteori med en mer specifik vinkling mot teorier om kapitalvaror. Därefter kommer en empirisk studie där faktorer som behandlats i teoridelen tas upp som beroendevariabler för efterfrågan på kapitalvaran bil. Slutsatserna som dras är att räntenivån påverkar bilinköp mest, troligen för att kreditkostnaderna utgör en allt större del av hushållens disponibla inkomster. Dessutom bekräftas det att inkomsten fluktuerar mer än konsumtionen och detta gäller också för hushållens konsumtion av nya bilar..

eWOM-kommunikation på Facebook & Prisjakt : En studie av skillnader i konsumenters uppfattning om eWOM

Purpose ? The purpose of this study is to identify and describe how consumer perceptions regarding information quality, sender credibility and effect of eWOM-communication differ between Facebook and Prisjakt.Approach ? Based on previous research an analytical model was designed. The parts in the model were the aspects of the problem which the present study aimed to examine. An experimental design was applied in which ten students at Örebro University were exposed to a scenario where they took part of eWOM-communication concerning a specific product on Facebook and Prisjakt and then had to answer questions in an interview. The analytical model formed the base of the interview guide used in the interview and the specific product was chosen with help from a focus group.Implication ? The study illustrates that consumers may perceive the quality higher on Prisjakt while the sender credibility can be perceived higher on Facebook.

Kartläggning av Modified Early Warning Score (MEWS) hos patienter med kirurgiska åkommor.

SAMMANFATTNING  Bakgrund: Patienter på kirurgavdelningar är komplexa såtillvida att de förutom den kirurgiska åkomman kan ha olika medicinska diagnoser vilket ofta komplicerar både vården, behandlingen samt medför svårigheter i att upptäcka ett försämrat tillstånd. För att kunna bedöma patientens tillstånd och få en uppfattning om hur denne mår måste objektiva och lätt mätbara parametrar användas.Modified Early Warning Score (MEWS) är ett poängsystem som mäter några av patientens vitala funktioner och baseras på sex mätbara/bedömningsbara  funktioner: andningsfrekvens, puls, systoliskt blodtryck, kroppstemperatur, vakenhet och urinmängd. Poängsumman varierar mellan 0 och 17, där 0 är normalt. Syfte: Att kartlägga fördelningen av poäng enligt MEWS hos akuta patienter med kirurgiska åkommor på två kirurgavdelningar på ett universitetssjukhus i Sverige samt undersöka vilka åtgärder som vidtagits vid respektive poäng enligt MEWS. Metod: Retrospektiv journalgranskningsstudie  där dokumentation av mätningar med MEWS för 94 patienter granskades. Resultat: Totalt återfanns 229 poäng enligt MEWS varav 76 var från mätningar vid ankomst till avdelning och resterande  153 från mätningar under fortsatt vårdtid. Antalet MEWS-mätningar per patient varierade mellan  1 och 31. Nitton åtgärder som ingår i sjuksköterskans profession kopplade till en poäng enligt MEWS återfanns.

Folkbibliotekets roll i det lokala samhället ? Tre kvalitativa fallstudier

The aim of this master?s study is to examine the function of the public library in the local community at present. I have searched for the answers to the following questions: Which position has the public library in the local cultural policy? What characterizes each library and which are the priorities? What is the local profile of the public library? What cooperation partners does the public library have and what do they mean to the library? Does the public library intensify the local community in any way? To answer this, I have made three qualitative case studies. Interviews and collection of documents were carried out in three different communities.
