The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
Konstruktion av anordning för att undersöka förslitning av syrebärarpartiklar för kemcyklisk förbränning
The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
Konsekvenser av principbaserade regelverk: En studie av säkringsredovisning på en svensk storbank
IASB is currently working with the replacement of IAS 39 Financial Instruments: Recognition and Measurement. The new standard IFRS 9 Financial Instruments is said to be based on principles as opposed to the more rules-based IAS 39. This thesis examines the third phase of the project regarding micro hedge accounting. The expressed goal from IASB is to provide more useful hedge accounting information by reducing complexity of the standard. To examine the potential effects of the transition from the rules based IAS 39 to the more principles based IFRS 9, we have performed a case study on a major Swedish bank.
Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog
Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.
Hantering av personuppgifter ? en arbetsmiljöfråga?
Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.
DISTRIKTSSKÖTERSKORS HÄLSOFRÄMJANDE OMVÅRDNADSÅTGÄRDER VID HYPERTONI : En litteraturstudie
Hypertoni är en folksjukdom som drabbar en femtedel av den svenska befolkningen. Orsaker till hypertoni kan vara livsstilsrelaterade, som stress, övervikt eller fysisk inaktivitet. Distriktssköterskor har som uppdrag att kontrollera patienters blodtryck, ge stöd och rådgivning till förändrad livsstil. Detta för att främja hälsa och förebygga hypertoni eller förbättra ett förhöjt blodtryck.Syftet med examensarbetet är att sammanställa befintlig kunskap från litteratur om distriktssköterskors hälsofrämjande omvårdnadsåtgärder till patienter med hypertoni.Examensarbetet är en litteraturstudie där kunskap från 12 vetenskapliga studier förts samman till ett nytt övergripande resultat, en metasyntes. Resultatet visar att de hälsofrämjande omvårdnadsåtgärder distriktssköterskor utför till patienter med hypertoni sker som Hälsoutbildning på standardiserat eller personcentrerat sätt.
Social isolering. En studie om a?siktspolarisering och normativ press i sociala medier
The purpose of this study was to look for tendencies that social media can contribute to exposing users to a stronger perception of opinion polarization, and further to see if the daily presence of social networking sites can put normative pressure on the users. The study was made using a survey with participants from Umea? University during the time frame of november-december 2014. The theoretical framework behind the study was mainly drawn from The Spiral Of Silence by Elisabeth Noelle-Neumann and was further supplemented with more current research, studying the effects from The Spiral Of Silence in the modern and more fragmented media landscape that exists now then when her theory was written. Further theoretical tools for analysis of the results came from Michel Foucault and his discussions in Discipline and punish, specifically his views on how surveillance can be discontinous in practice, but still permanent in it?s effects.The results of this study indicates that social media users tend to isolate themselves from uncomfortable opinions, and do not follow or read opinions they do not already agree with.
Anestesisjuksköterskors upplevelser av sin fysiska och psykosociala arbetsmiljö
Health care is increasingly complex, which increases the demand for knowledge and expertise. Despite this, the share of specialized nurses, including anaesthesia nurses, has decreased from 65% to 48% from year 1995 to year 2008, according to statistics from the National Board of Health and Welfare (Socialstyrelsen) in 2010. Studies indicate that there may be various factors in the work environment that anaesthesia nurses, choose to leave the anaesthesia profession. The purpose of this study was to examine how anaesthesia nurses experienced the physical and psychosocial work. The study was conducted as a descriptive study with qualitative approach.
Demokratisk Transition : Fallen Slovenien och Lettland
Slovenia and Latvia are two examples of countries which have gone through a successful democratic transition. They were both under authoritarian rule and command economy up until their declarations of independence in the early 90s. Today they have a functional market economy and political pluralism. I have examined transition theories highlighted by Jonas Linde and Joakim Ekman and from these theories sought the explanations to what lies behind the successful transitions of these two countries. The transition in Slovenia was affected by liberalization from within the ruling communist party which then controlled much of the transition process. A relatively large civil society and the fact that Slovenia was not involved in the Balkan War also contributed to the short process.
Måltiden som lärandesituation i förskolan : en kvalitativ studie om pedagogers syn på barns övergripande och hälsofrämjande lärande i förskolan genom den pedagogiska måltiden
The purpose of my study has been to find out how four preschool teachers at four different preschools looks at the pedagogical meal from a health and overall learning perspective. I also want to examine how, through the pedagogical meal the preschool teacher works to promote children´s learning and give them an understanding of need to safeguard their health. To achieve my aim I set the following questions;What are the different types of learning preschool teachers believe that children can acquire the basis of the pedagogic meal?How do preschool teachers describe their work from the pedagogical meal to benefit children´s overall learning?How do preschool teachers describe their work at the pedagogical meal for the children to gain an understanding of their health?The study is based on a qualitative method with interviews and observations, triangulation. The theoretical approach to this study is based on the socio-cultural perspective to learning and development.

Konstruktion och prototypframtagning av pallväxlare
This thesis was conducted at AB Fredr Wagner in Ösmo in Nynäshamn, Sweden.AB Fredr Wagner provides solutions for the graphic industry and has been asked by acustomer to develop a product that can simplify handling of EUR-pallets, namely amechanical arrangement, further called pallet exchanger that can switch from anempty pallet to a fully loaded one using only hand force.The goal with the thesis was to create design documents for a pallet exchanger, andalso from those documents to manufacture a prototype for testing and evaluation.A field trip was made to the customer, IKAB mailing in Huddinge, where the palletexchanger is thought to be placed. The purpose of this field trip was to get an insightinto the current work condition and need of change, as well as to gather informationregarding the requirements when it comes to size and robustness of the palletexchanger. Existing equipment on the market that can perform similar tasks werestudied in order to find an optimal solution for the actual pallet exchanger.After the field trip and gathering of information the concept generating phase began.The method used for generating concepts was brainstorming. To decide on whichconcept to use, a concept selection matrix was created. The selection criteriaincluded in the matrix came from the requirements for the pallet exchanger.
Validering av smärtformulär för katt
The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use.
Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.
