Askor från avfallsförbränning farligt avfall eller en framtida resurs
I Sverige ökar förbränningen av avfall som inte är ett helt definierbart bränsle. Detta är i mångt och mycket ekonomiskt och miljömässigt försvarbart genom den höga kvalitén på rökasreningen, som garanterar att en mycket liten del av föroreningar når atmosfären, utan dessa koncentreras i askorna. Avfallsaskor går till stor del till deponier och används där för sluttäckning eller för att deponeras, samt att en stor mängd flygaska transporteras till Langöya. Inom en tioårsperiod kommer deponierna vara sluttäckta och Langöya uppfyllt, samtidigt som mängden avfallsaskor ökar, vilket innebär krav på nya lösningar. Orsaken till att framförallt flygaskan klassas som farligt avfall är koncentrationen av tungmetaller och föroreningar som härrör från bränslet.

It?s the time aspect that?s going to be examined in this thesis. The purpose of this thesis is that the student in question is to investigate the activities of the installers that works with this project, identifying where and how time losses occur and come up with suggestions for improvement.Methods used in this work is literature studies, observational studies and interviews.
Mödrars upplevelser av kängurumetoden
När ett underburet barn föds behöver det ofta vård på en neonatalavdelning vilket innebär att det måste skiljas från sin mamma. Denna separation är en stor påfrestning för både barn och mor. Många mödrar upplever känslor av besvikelse, maktlöshet och sorg samtidigt som de ofta är oroliga för barnet. Genom kängurumetoden kan mammor och barn genom hudkontakt få möjlighet att få vara tillsammans och lära känna varandra, samtidigt som metoden stödjer alla de behov som ett underburet barn har. Den forskning som idag finns inom området berör främst hur barnet påverkas av kängurumetoden.
?Det här är ett fritt land för mig.? : En studie om synen på hedersrelaterat förtryck bland utsatta kvinnor och professionella socialarbetare.
AbstractWith the murder of Fadime in 2002 honor killings and honour related oppression became a subject of wide public debate. The question was raised whether the Swedish social services had the knowledge and the resources necessary to face the issue with honor related oppression.This study is about the views on honor related oppression among oppressed women and professional social workers and aims to explore the relationship between social worker and client in an honor related context. Does the risk of culture clashes pose a problem in dealing with the Swedish authorities and do Swedish social workers have the necessary tools to help the, often young, oppressed women that seek their aid? This is a qualitative study based on five individual interviews: Two former victims of honour related oppression, two professional social workers and one relative of a young girl who was the victim of an honor killing.Observations:The social workers found that they had adequate resources at hand but that awareness among employees in the social services needed to be improved.The clients felt that the help they?ve received from the social services was helpful but that more information to the public about available resources was necessary along with a better understanding of the differences between their own culture and that of the Swedish society. The clients expressed that the realization that they were being oppressed didn?t come overnight.
Det mångfacetterade islam : En studie i hur islam och muslimer framställs i ledare
The way in which media discusses religion has changed over time. Due to the separation of state and church in 2000, the Swedish state to a lesser extent legitimizes its political ruling with references to religious concepts. As a result, a higher tolerance towards religious minorities can be said to have taken place. This is an ambiguous change however, where critique raised towards religious practices and expressions of minorities also occurs to a higher extent. The public debate is in large part conducted through the media, but is also seen to be produced and reproduced through the media?s discourse.
Lek för lärande eller lekandets lek : Pedagogers syn på barns egen lek och lärande
The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.
Demokratisering i Östeuropa : En flerfallstudie med fokus på Estland och Moldavien

High Orbit Ion Cannon : Går det att skydda sig?
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
Hållbarhetsredovisning : En studie kring skillnader mellan granskade respektive icke granskade företag
The purpose of this study was to examine the differences between non-audited and audited sustainability reports and in that way indicate the significance of auditing to the contents of a sustainability report. The study was delimited to include three companies that create sustainability reports according to GRI guidelines, and also have changed from non-audited to audited reports.The study is an exploratory study where we started from companies that follow GRI's standard and who have changed from being non-assured to assured and certified. In order to examine any differences we have started out from corporate sustainability reports and with the basis of these latter gather those changes which may have occurred during the changeover. We therefore chose to conduct a literature review on each company's non-audited sustainability reports and compare them with each company's audited and certified sustainability reports. Furthermore our study has been made on the basis of an assessment model based on the concepts of materiality, completeness and comparability.The study showed that the audited sustainability reports in all companies were more focused and more detailed about the aspects GRI established for the performance indicators.
Vilka faktorer påverkar beslut om förtida projektavslut? : En fallstudie av utvecklingsprojekt hos svenska industriföretag
Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.
Familjens delaktighet. En litteraturstudie om familjecentrerad vård inom barnsjukvård.
Introduktion: Familjecentrerad vård innebär en process där involvering och deltagande leder till professionellt stöd för barn och familj. Detta karaktäriseras av en relation mellan vårdpersonal och familj där båda parter tar åtar sig ansvar för barnets omvårdnad och hälsovård. För barn upplevs en separation från föräldrarna ofta som ett stort trauma, varför det är viktigt att föräldrarna är närvarande under sjukhusvistelsen. Föräldrar kan bland annat bidra med tröst och stöd till barnet. Familjecentrerad vård ger således en möjlighet för familjen att vara delaktig i barnets vård.
Beräkningsmodell för massbalanser för Slottshagens reningsverk
In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..
Hälsofrämjande naturelement : argument för att prioritera en grönare arbetsplats
Psykisk ohälsa är sedan flera år tillbaka den främsta orsaken till längre sjukskrivningar i Sverige och Försäkringskassan har dragit slutsatsen att en stor del av arbetet med att förebygga psykisk ohälsa bör ske på våra arbetsplatser. En urban livsstil, vilket inkluderar fler timmar på kontoret, tidsbrist och separation från naturen kan ge skadliga effekter på både vår allmänna och personliga hälsa och lycka. Litteraturstudien i det här examensarbetet ämnar sammanställa evidensbaserad forskning som berör effekterna av kontakt med naturelement på arbetsplatsen, för att belysa naturelements eventuella positiva påverkan på den anställde. Studien avgränsade sig till arbetsplatser där de anställdas arbetsuppgifter huvudsakligen är lokaliserade inne i en byggnad och kontakten till naturelementen delades in i tre olika kategorier; direkt inomhuskontakt med naturelement, passiv kontakt med naturelement och direkt utomhuskontakt med naturelement.
Litteraturstudien visade att samtliga tre kontakter till naturelement kunde understödja flertalet positiva effekter på den anställde som till exempel ökat välbefinnande, arbetstillfredsställelse, trivsel och välmående. Resultaten pekade också på en komplexitet i frågan om naturelements effekter och det var svårt att dra några slutsatser angående effekternas storlek eller betydelse i praktiken.
Lean Produktion på mjölkföretag - fungerar det?
The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.
