Optimering av indunstningsprocess

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

Vård av patienter i livets slutskede och deras anhöriga : undersköterskors beskrivningar

Palliative care is founded on a holistic attitude, with the goal to alleviate suffering when a cure is no longer possible. Palliative care affirms life and regards dying as a normal process, providing possibilities of a quality time for the patient and family. Studies show that an increasing number of people choose to live the final phase of their life in their own home. A requirement for end of life care is an effective team work, where the nurse is responsible for more advanced care, and the caregiver?s provides the immediate care.

Ta täten i loppet om innovation: Fostran av intraprenörskap i stora organisationer - En studie av Volvos New River Valley-fabrik

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

From the experience of the first two parts of the report a general help for planning a demolition was shaped.

När tar man fram kondomen? : En studie om lärares attityder till UR och RFSU:s projekt för en bättre sexualundervisning

The debate in the media on a new Swedish sex education movie sparked our interest in this study. The twenty-eight minutes long movie ?Sex on the map? is the first of it?s kind in twenty-five years. It is also part of a bigger sex educational project that contains, apart from the movie, a book about sex education, a documentary and a teachers guide. The project is a co-production between the Swedish Educational Broadcasting Company (UR) and the Swedish Association for Sexuality Education (RFSU).We were interested in how teachers received information about the project, and what their attitudes were towards it.

3D modelling of a Laser Welding Cell for movie presentation : making of the movie

This report describes a Bachelor thesis work in which a robotised laser welding cell has been modelled and simulated for the purpose of making a presentation movie. The report shows that the work has been concentrated on making the movie from the modelling phase through the recording of the movie and ending up with the editing of the final presentation movie. A pre-study was made prior the Bachelor thesis work. In the pre-study a literature study was conducted about measurement and calibration of a welding cell. Measurement of almost all equipment in the entire cell was also conducted in the pre-study.

Konst på internet idag : En retorikanalys av konstverksamma organisationers självpresentationer

This is a qualitative study about Art transformation and commodification in the digital age. The study applies a rhetoric analysis with the aim to understand how art sellers, gallery owners and entrepreneurs take part in this transformation process through their websites? presentation texts ?about us?. The analysis is related to communication theories but it is also inspired by other theories such as Gramsci?s hegemony theory and Bourdieu?s cultural critical theory.

Improvements in milking management through imitation of calf behaviour

Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.

Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

Analoga möten i en digital tid - En kartläggning av Socialdemokraternas och Moderaternas dörrknackningskampanjer under 2014

2014 is a special year in Sweden: for the first time elections to the European parliament and the national elections coincides, creating a"Super election year". This year has also seen the rebirth of an old way of campaigning: door-to-door canvassing. For the first time in 50 years the two biggest political parties, the Social Democrats and the Moderate Party, have decided to create a campaign based on personal meetings with the voters in their own home. To investigate this old-new way of campaigning, this study presents an overview of the history of door-to-door canvassing in Sweden and the research in political marketing associated with the phenomena. Based on that, a new model is constructed to help analyze and map the Swedish canvassing-campaigns.

Informationssökning för barn och ungdomar politiska dokument och konkret verksamhet

The topic of this essay is information seeking for children and young people in municipal libraries. This is based in the growing need for information seeking skills in the Information Society. Policy documents on the topic are scrutinized and related to a concrete praxis. Data has been collected through two case studies; one carried out in Ronneby and one in Trandared, Borås. These cases where chosen because of the existence of a local policy for library skills and information search for 6 to 12-year-olds.

Interferences during analysis of polyphenols in fruit juices

One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

Döden är livsviktig : fem kuratorers bemötande av obotligt sjuka och deras bild av de sjukas upplevelser

The aim of this undergraduate thesis was to explore how the welfare officers at palliative units in Stockholm respond to the patients? thoughts and experiences during the last phase of life, as well as exploring their picture of the patients experiences. The research questions of the study were:? How do the welfare officers relate to the patients? experience of their death? ? In what way do the welfare officers respond to the dying patient and his or her experiences?? What knowledge/experience do the welfare officers have and what knowledge/experience do they consider is needed in their profession?To answer the research questions a qualitative method was used where five welfare officers in three different palliative units were interviewed. The empirical material was analysed through meaning concentration and are presented using exact quotations.

Modulbyggd förskola - Framtiden?

In 1999 the childbearing increased, which in combination with the closure of a number ofpreschools led to the shortage and reduced capacity in available places for youngchildren. The lack of places in preschools has led us to try to find a solution to theproblem and in order to solve the problem we have interviewed personnel of preschoolsin Halmstad. The persons we met were asked to list advantages and disadvantages oftheir preschool and also to come up with innovative solutions and new ideas of how todevelop a satisfactory preschool. This was the basis for us when we drew our drawingsand our main objective was to find a new template for the development of pre-fabricatedpreschools.When drawing a new and modern preschool a number of considerations have to be made,first of all the main objective for the children is play and playtime, a second objective issound reduction and laws about sound reduction. Another consideration is how toconstruct the building and which method to be used, for instance should industrialtechniques be considered and pros and cons be listed.The main disappointment amongst the preschool personnel was that they had noinfluence in the planning stage of the new development of the preschool.

Grupperingar i en nysammansatt klass

The purpose of this paper is to try to get an understanding of the underlying causes and reasons that students starting in seventh grade junior high school seek out a particular group, and the extent to which they do so.The work is based on the questions: How do students perceive the meeting with their prospective bench-companion in a new composite class? What should a teacher consider when it comes to bench placement in a new composite class? Do the students change, and if so to what extent, friends when they start high school? What are the factors that affect/have affected the students' choice of friends? How large a role does the school play for pupils relationships? What thoughts and feelings do the students have regarding new encounters?I have conducted in-depth interviews with six adolescents in grade seven as the basis for the understanding of how students relate to group selection and group affiliation, and I have then compared this material with previous research on the subject. Furthermore I have availed myself of literature in social- and group psychology.The conclusion which has emerged is that the most important component of a group-process is the sense of solidarity and security, and the results show that students largely retain their old relationships rather than adding new, when they start high school. Hence the teacher plays an important role in ensuring that any imbalance in the group is offset and make sure that nobody is excluded, but also to help make room for new groups and be aware of the sensitive and responsive phase of life that the young people are in..
