Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.

Tidigare gjorda studier tyder på att IVA patienter upplever sömnstörningar som ett stort problem. Syfte: Att beskriva sömnförändringar, sömnpåverkande faktorer och sömnförbättrande omvårdnadsåtgärder för IVA-patienter. Metod: Databassökning gjordes och nyckelord har identifierats.
Anpassning och optimering av checkprogram för AW139
Presently Sjöfartsverket do their maintenance according to a standard program, which means that every maintenance task will be done when the task limit occurs. This leads to a very long downtime for the aircraft in some occasions and very short downtime in others. The goal with this work is to reach a higher regularity of the aircraft operation. To reach a higher regularity for the operational needs, this work will present a hypothetic better maintenance concept for Swedish Maritime Administration. The concept is based on equalized maintenance structure, which means that every maintenance occasions are meant to take the same time to perform.
Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Mätning av implementeringen av lean inom sjukvård
The purpose of this thesis is to discuss how an instrument originally developed for measuring changes toward lean thinking inservice organizations in general should be adjusted in order to be of use in service organizations within the healthcare sector, andin hospital organizations in specific. The adjustments are suggested based on difficulties specifically arising when implementinglean within the healthcare sector.Thesis starting point is a pre-existing lean assessment instrument developed for service organizations in general. The thesis appliesa qualitative method and integrates literature from the health care sector and lean production movement with the expertise of tenacademics and practitioners in order to find difficulties associated with the implementation of lean within the healthcare sector.These difficulties then lie as the substratum for the adjustments suggested to be made on the instrument.The thesis finds that lean, as a philosophy, does not differ between service organizations in general and service organizationswithin healthcare settings. However, due to deficits in the general understanding of lean some adaptions on the instrument mustbe made. First, some words associated with production must be changed to words associated with healthcare.
Konsten att mäta tjänstekvalitet : En utvärdering av tre instrument för att mäta tjänstekvalitet i kollektivtrafiken
The purpose of this study is to analyze and evaluate the suitability of the three instruments SERVQUAL, SERVPERF and Zone of tolerance to measure service quality, from the respondents' perspective. This study has been carried out by a quantitative method in which respondents answered three questionnaires, which was based on the three instruments. The SERVQUAL instrument is a revised version based on criticism by Carman (1990). It is based on the five dimensions; reliability, responsiveness, assurance, empathy and tangibility, with 22 items in which each dimension is associated with a number of items. SERVPERF is the instrument most similar to SERVQUAL and is also composed of the same five dimensions.
Från allians till aktiv autonomi : En kvalitativ studie av förändringar i handledarstilen
Bakgrund: Trotts att handledningen anses vara en vital del av psykoterapeutisk utbildning, är inte utbildning av handledare en självklarhet, och mera forskning behövs kring vad som utgör en bra handledarutbildning.Syfte: Den här undersökningen hade för huvudsyfte att analysera eventuella förändringar i handledarstil hos en handledarkandidat under S:t Lukas utbildningsinstitutets handledarutbildning 2008-2009.Metod: Materialet bestod av transkriberingar av handledarens tre handledningstimmar med den handledde terapeuten från början av handledarutbildningen, och tre från slutet. Med hjälp av grundad teori togs fram kategorier som beskrev handledarstilen ur fyra aspekter: styrning, allians, inlärningsstil, och fokus.Resultat: Jämförelse mellan handledarstilen i början och vid slutet av utbildningen visade på en ökad aktivitet hos handledaren, fr.a. i undersökning och hållandet av fokus på viktiga teman. Tydliggörande minskade. Mot slutet av utbildningen ökade också handledarens tillit på alliansen, som tålde mer brott.
Nutrient effects on microorganism communities in nutrient poor soils
Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest.
The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.
Idéanalys av Centerpartiets partiideologi 2001-2013 : Är det medlemmar eller väljare som bestämmer Centerpartiets ideologi?
AbstractWhen the Swedish Centre Party, Centerpartiet, just before Christmas 2012 released a draft for new program of ideas a powerful "winter storm" broke out. Ideas that Centerpartiet would abolish compulsory schooling and the right to inheritance and allow polygamy are just a few of the things that cause alarm.It's not the first time during the last years the Centre Party is associated with neo-liberal elements in their party?s ideology. In 2007 Erik Ullenhag criticized Centerpartiet for their new neo-liberalism was a danger to the alliance.The aim of this study is to investigate whether it is possible to see a change in Centerpartiets ideology and how deep it is. From an idea analytical approach based on ideal types, created for social liberalism, neoliberalism and ecohumanism, the party programs from 2001 and 2013 are studied.
Sjuksköterskans upplevelse av att bedriva psykiatrisk omvårdnad : En litteraturstudie
Background: Studies have shown that 66 children and teenagers in Sweden suffers from brain tumor every year. Children and teenagers who can´t participate in the regular school for a longer time for whatever reason, have by the school law the right to education in hospitals or institutions. Education that take place in other places than school most try to follow the same guidelines as his/hers usual school. This applies to students in elementary school, compulsory school, special school, Sami school, secondary school and upper secondary school.Purpose: The purpose of this study was to find out how three teachers at a hospital school plans their work with children in grade from 1 to 3, who suffer from cancer, especially brain tumor. How can the teachers at the hospital school plan and organize their teaching so that it´s possible for the children whit brain tumor to feel as normal as possible. How does the common work between the consultant nurse, teachers at the hospitals and their ordinary school prevent the children to feel like an outsider?Method: I have chosen to do a qualitative study followed by three interviews whit three informants who works at a hospital school.
Varumärkesbyggande processer
Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.
