Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
Patterns of Touch : En analys av touchspel till iPad utifrån gränssnittspatterns
For this essay we used pattern theory from interface design and applied it in an analysis of touch games. In order to make full use of the patterns, we selected five of them and adapted these slightly with the help of game related patterns to be useful for the framework of this essay. The selection of games were the top eight games on the App Store?s ?What?s Hot?. The results showed, among other things, that the games had a clear focus on getting a pleasant apperance, and they did it relatively well.
Barns anknytning i förskolan : Separationsångest mellan barn och pedagog
My essay is about a dilemma that came up on a preschool that I worked in. My purpose with my essay is to examine and to get an understanding for what children with attachement and separation anxiety goes through, and how a preschool teacher the best way can help them.The background story is about a boy named Sixten (not his real name). When separated from one of the preschool teachers Sixten exhibits a great deal of separation anxiety. In the story I give some clear examples of situations where Sixten displays this separation anxiety. I have in the essay viewed it from different perspectives and I have questioned my own role as an educator, but also my entire team.
Verksamhetsstyrning i grundskolan - En väg till goda förutsättningar för inlärning
This study investigates how performance management in primary schools can facilitate learning, relating to theories of efficient schools. This is done through a qualitative study of the performance management systems in two public primary schools in Sweden. The schools selected were similar in all major aspects, except pupil grades, where there was a clear difference between the schools. The analysis revealed differences in how the schools handled the process of management by objectives, the professional development of teachers as well as routines, rules, and policies. We conclude that having a rooted process for management by objectives, professional development of teachers, and clearly formalized values, gives a school a good foundation to support a pupil's learning and development..
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Ridningens pedagogik
The purpose of this study has been to look how pedagogic process interacts in horse riding lessons. In order to research this problem I have used an ethnographic approach and during a week I observed ten riding lessons in two separate Riding house in the south of Sweden. In my theoretical frame I have used Michel Foucault ?Discipline and punish? as a toll to make clear how dominance and submission is present and active in the horse riding education.
The conclusion shows how dominant power rules by its presence and creates submission, stability and feeling of security. The discipline is used to create a feeling that will bring the riders to new experience and develop their talent.
Konstnärlig process och måluppfyllelse i Lunds Vokalensemble - "...en lite sån magisk upplevelse"

Qualitative interviews and observations were used as a method. Four singers and the director participated to the interviews. The results show that the choir's artistic goals have quite an influence on many aspects of the choir's work, both in a musical and a social way.
Barns självvalda läsning
The purpose of this thesis is to gain insight into children`s voluntary reading in their spare time. I have focused on printed books and none of the digitally published Medias. I want to examine how children experience the power adult`s exercise over their chose of books and also why they choose the books they do. The method of this study is qualitative with interviews of six 10 years old children. I conducted the interviews detachedly and I have used two different point of view for my study; Aidan Chamber`s ?Reading Circle? and Barbro Johanssons opinions if children`s participation in terms of their voluntarily book selection.I have also studied other researchers and author´s writings about literacy, children´s reading habits, adults´ attitudes to children´s reading and children´s passion for reading.During my study it became clear that children who like to read prefer to read detective stories for children, a result that also earlier investigations reached..
Marknadsinriktad miljökommunikation på Internet : försäkringsbolaget Folksam
Many companies are presently investing in different types of environmental strategies, and it is varying to what level they channel their resources to environmental efforts. It is also diverging to what extent organizations effort to profile themselves as environmentally conscious. This can be due to difficulties in reaching out to customers and to finding the most efficient method of green marketing communication.
The aim of this study is to analyse how an insurance company more actively can communicate environmental matters foremost in their contact with customers. One can in different mediums daily follow debates and discussions concerning the environment. Many insurance companies have also identified their role in performing green work.
Temporala och spatiala egenskaper i makroseismiska katalogdata 1375-2000
I Sverige uppmäts årligen runt 700 jordskalv, men ytterst få skalv är av ansenlig styrka. Andelen skalv som vi människor har förmåga att känna av är därav relativt liten. Denna studie är baserad på makroseismisk katalogdata över svenska jordskalv mellan åren 1375-2000. Att studien är makroseismisk innebär att den är icke-instrumentell och därmed baserad på mänskliga observationer i de jordbävningsdrabbade områdena. Katalogen som legat till grund för undersökningen består av 883 fall och innehåller information om tid för skalvet, utbredning och styrka.

En jämförande studie mellan pojkar och flickor : om attityden till psykisk ohälsa
The purpose of this study is to explore students? perceptions and experiences of the school-subject Swedish. Ten qualitative interviews with students in school year nine have been carried out and the results of these interviews constitute the basis of this study. The result shows that students have a straight-forward attitude towards Swedish as a school-subject. The students identify skills such as reading, writing and speaking, and work in school mainly concerns perfecting these skills. The students think of Swedish as a subject with a clear purpose and find it important and useful. The result also shows that the students want grading for the purpose of further motivation.

Rural development in Southeast Sweden- three different views and their consequences for the agrarian landscapeThis paper deals with the future for the rural areas of the southeast province of Östergötland, Sweden. The aim is to unveil, analyse and compare different views on rural development and their consequences for the agrarian landscape. Three views are considered, namely that of the different levels of Governments and their departments, that of the farmers and landowners and, finaly, that of the inhabitants of the rural areas.Differences in the views upon rural development is reflected in differences in the ways of thinking of landscapes. Is the open, and actively cultivated, landscape the ideal for all? Who is to decide what needs or ought to be done to achieve certain desired values and/or goals ? and who pays for it? The one thing that is, and should be, clear from the beginning is that all development, whether positive or negative in an area, bears consequences for the landscape.
