Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB
The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.
MOLNU : Att utveckla ett gemensamt gränssnitt
Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.
Engagerade ungdomar : en hållbar energistrategi
The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a).
The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.
Undersökning av deponerat ferrokromstoft : Utvärdering av ny behandlingsmetod
The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.
Energikostnader vid uttorkning av byggfukt i betongbjälklag : En beräkningsnyckel för uttorkningsplaner
Fukthantering är idag, trots god kunskap inom ämnet, ett stort problem inom byggproduktion då tunga betongstommar ska torkas ut under pressade tidsplaner. Det finns en uppsjö av beräkningsmetoder och hjälpmedel, exempelvis ByggaF och Torka S. Däremot finns inget enkelt sätt att kombinera uttorkning, energiåtgång och kostnader som är användbart i produktionen.Miljön är kanske ett av det här århundradets största samhällsproblem. Lokala brister kan få globala konsekvenser och för att bygga ett hållbart samhälle måste detaljnivån studeras. Byggbranschen är en stor energibrukare där stor vikt på energibesparingar läggs i förvaltningsskedet, medan det försummas i produktionsskedet.
Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden
Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.
En kvantitativ studie om lärares inställning till och arbete med Nationella Prov : En enkätstudie i syfte att beskriva lärares uppfattning av huruvida NP bidrar till likvärdig bedömning och ökad måluppfyllelse i mellan ? och högstadiet.
The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.
(O)motiverad Invandrarpolitik : en studie om motiven att frångå invandrarpolitik och införa integrationspolitik
An effective Integration policy is important in Sweden while our government has decided and committed to be a country where everybody will be given the same opportunities. There is a greater awareness in today?s society of integration policy goals such as equal rights, responsibilities and opportunities for all. In a number of areas, however, the disparities between immigrants and Swedish-born citizens are still too large.The Swedish Riksdag decided on integration policy in 1997. The main task for this thesis will be to examine the motive behind the Government's decision to revoke immigrations policy and introduce integration policy.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Ett resecentrums betydelse för en stadskärna . : En studie om Kramfors resecentrums funktion och relation till den urbana omgivningen, samt upplevelsen av denna
The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.
Bestyrkande av hållbarhetsredovisning : kostnad & nytta
Sustainability reports have during the last decade had a strong development. Both in terms of establishing a sustainability assurance, in its form, and get it assured together with standards, principles and regulations which organisations and accountants have utilized. The growth of sustainability reports and the choice of getting them assured have in particular favoured the accounting business. Due to this result, some critics have voiced that assuring a sustainability report gain accounting firms more than it gains the actual organisation. Other say that it is necessary in order to increase the credibility and the eligibility of the report, while it also has become a requirement from stakeholders.
Vem får jobbet? : En studie om de kompetenser som efterfrågas för yrket inköpsassistent
I den här uppsatsen undersökts det hur rekryteringsprocessen av inköpsassistenter ser ut i teori och praktik och vilka kompetenser yrket efterfrågar. Ämnet är aktuellt då yrkesrollen som inköpsassistent är svår att definiera och teori har påvisat att rekrytering försvåras av det faktum. Det kan i sin tur leda till felrekryteringar som kan ge stora konsekvenser i ett företag. Ämnet är också relevant då förändringar inom modebranschen har påverkat yrkesrollerna inom branschen i hög takt vilket resulterat i att samma yrkesroll har olika innebörd på olika företag. Förändringar ställer högre och delvis helt nya krav på rekryterare inom branschen.

This master thesis covers the design of a special garden room, The Hardscape Room, in The Rehabilitation Gardens at Alnarp, in southern Sweden, as well as describes the design process. The Rehabilitation Gardens are intended to serve several purposes. It will offer horticultural therapeutic treatment programs for people diagnosed as having had burnout disease for an extended period. Research is also aimed at studying the possible impact of different garden design hypotheses as well as different forms of horticultural therapy. In The Rehabilitation Gardens at Alnarp the most extreme and demanding garden room focused on cultivation and horticultural therapy is The Hardscape Room.
Att styra säkerhet med siffror : En essä om (att se) gränser
Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.
