Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär
The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
Design Program for Dessie Campus, Wollo University, Ethiopia
A geographical position and its social, cultural and political context as well as climate
and specific physical characteristics define the scope for a landscape design project.
This has become clearer for us in our master project where we have made a Design
Program for the outdoor environment of Wollo University in Dessie, Ethiopia and
analysed and reflected on the work and process. The aim for the project has been
to design an attractive and functional outdoor environment for the Campus, based
on the inventories and the needs and wishes of clients and users. But, the aim has
also been for us as landscape architect students to gain a greater knowledge about
landscape architecture and the design process by position ourselves outside our usual
context. The method has been open and seeking where the site, literature studies,
dialogues with people and our own experiences from the field study in Ethiopia has
influenced the work.
Wollo University is situated 400 kilometers north of Addis Ababa, in a
mountainous landscape. It faces problems of heavy rainfall during the summer,
soil erosion, a lack of essential facilities, and is still a construction site with empty
spaces in-between buildings and infrastructure.
Vilka är dagens krav på gårdsverkstaden? :
After been told that an ordinary winter service for our combine should cost more than
20000 SEK, not included spare parts, I decided to write this paper about today?s
requirement of the workshop on a farm. I think that the lack of proper premises is the
reason way not more of the ordinary machinery maintenance or upkeep is performed on
the farm.
When I did my literature survey I found that the Swedish environmental code, set by the
Swedish law regulate how drain or sewer should be built. The environmental code
however leaves a lot for your own interpretation. It might not be so bad but it must be
very hard for the local environmental office to interpretation the regulations, since they
are the ones that gives permission for the sewer in your workshop.
Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.

Utveckling av nyckeltal för logistiska tjänster : En studie vid logistikföretaget Foria
The purpose of this thesis is to identify and define Key Perfomance Indicators (KPIs) and value adding services which are used to describe the quality of Forias logistics services from different aspects. The KPIs should be attractive to both Foria and their customers, with the aim to strengthen the interaction between both parties.The basis for this work is a research in which a literature review and a survey of the market for Swedish logistic service providers were carried out. An analysis of the present situation of Foria was carried out, where a number of people in the company were interviewed. These elements were used together with definitions of KPIs to perform the analysis of the work.The result of the work is ten KPIs that have been created and developed for Foria and which are considered to be attractive to both Foria and the selected customers. The KPIs are: · ECO-driving (binary) ? the company has ECO-driving-educated drivers· ECO-driving (comparison figure) ? all drivers individual driving and its resulting exhaust emissions are compared· The environmental impact ? a total of exhaust emissions from all vehicles belonging to a single business, measured in tonne-kilometres· Complete order ? portion of fields with accurate information (in an order), with the possibility of error categorization· Delivery reliability ? time difference between expected and actual delivery, average for all orders· On-time ? the number of days and hours of difference between the expected and the actual time, for all activities of the order· On-time (activity) ? the number of hours and minutes of difference between the expected and the actual time, for each individual activity of the order· Divergence ? a categorization of all causes of divergence and its responsible department· Level of integration ? the level of cooperation between the logistic service provider and the customer· Customer satisfaction ? how well an order will meet the expectations of the customer The KPIs are described in detail with definitions, how they can be used and what is required to implement them in the service process of Foria.

Driva tulpaner i näringslösning eller i jord :
The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands.
There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

Samverkan mellan bibliotekarie och lärare kring elever med dyslexi : En intervjustudie av fyra bibliotekariers erfarenheter kring elever med dyslexi och samverkan med lärare kring dyslektiska elever
This research focus on key groups; students with dyslexia, librarians and teachers, and interaction between these two professional groups regarding students with dyslexia. In searching for the exchange of knowledge and experience to meet dyslexic students needs, I have in this study turned the attention to librarians and their experiences with students with dyslexia.The purpose of the research has been through semi-structured qualitative interviews with four librarians, to explore and describe how they experience their work, in working with pupils with severe reading and writing problems, dyslexia, and interaction with teachers on this user group. The qualitative approach in the gathering of the empirical evidence is based on a desire to have an indepth and thoroughly understanding of the librarians experience.All informants in this study indicate that they see it as a natural part of their duty to keep themselves updated about dyslexia and what materials to suit the dyslexic user group. The informants have knowledge of dyslexia and have great knowledge and keep abreast on the latest technology of compensatory aids - alternative tools.The informants have primary a consulting and supply function for teachers and dyslexic students, where they are consulted on suitable material in both fiction and facts in various disciplines. The informants highlights the importance of planning and preparation time to find suitable material, as audio books or easy read, so students who have a need for this also can be provided.
Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling
Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.
