Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Att närma sig Boden :
approaching Boden deals with the approaching of a city, both
in a physical sense ? along the road ? and in a spiritual sense ? in
mind. The physical encounter with a city is represented by the
experience of the road and its surroundings, while the spiritual
encounter is represented by the idea of the city that we already
have, or will get, in our minds. We have in this degree project
approached Boden through a thoroughly analysis of both the entrance
roads and the city itself.
In this degree project we are looking for ways of how to create
characteristic and interesting entrance roads to a city, with Boden
as an example. This demands knowledge about the problems
involving entrance roads as well as the distinctive features of the
city.
Etnicitet och demokratisering i dagens Rwanda : En kvalitativ studie om etnicitet och demokratisering i Rwanda
The purpose of this study is to explain if the existence of ethnic groups in Rwanda has complicated its democratization and explain what opportunities Rwanda has to be democratized. To fulfill the purpose of the study, I intend to answer two questions: 1) Does the existence of ethnic groups obstructed democratization in Rwanda? and 2) What opportunities has Rwanda to be democratized? To answer the first research question Dahl's theory of subcultures and democratization is used and to answer the second research question van de Walle's theory of democratization is used in the region of sub-Saharan Africa. Literature used in the study are Dahl's Polyarchy and van de Walle Africa?s range of regimes and Freedom House annual reports.
Den sociala dimensionen av EU-medborgarskapet
Since the introduction of the European citizenship in the Maastricht treaty, social rights havetaken a back seat to the economic and political elements. Nevertheless, over the past yearssocial issues have been increasingly included on the agenda following the universalrecognition of challenges resulting from further economic integration and demographicchange. The extensive research on European social policy so far tend to focus on initiativesput forward by the European Commission, and offers little to explain the multitude of lines ofreasoning on how far EU social policy should be taken or why it still remains one of the leastdeveloped policy areas. By examining plenary debates in the European Parliament concerningfamily policy, this Bachelor thesis aims to describe the complex of problems connected to afurther development of the social dimension of the European citizenship.The analysis finds that the most imminent problems impeding an expansion of the EU familypolicy lie not only in the many clashes of opinions between advocates of the various existingwelfare models, but also in the conflicts of interests and the different levels of ambitionbetween EU institutions - most notably the Commission and the European Parliament..
Utomhusbruk. Produkter formgivna för utomhusvistelser
My thesis was based on studying what really happens when Swedes move their beloved kitchen outdoors.?What kind of problems andpossibilities appears in this enviroment? First, I unbiassed examined the traditional kitchen in general to get a better view of how an outdoorkitchen could function in a country that have diffrent seasons. I intervjued an interior designer specialized in kitchenplanning to get abetter view. One thing that came up was that the experince of beeing outdoor sometimes puts functionality aside. I located different needs inthe outdoor kitchen enviroment and decided to work futher with one of them, outdoor lightning.The result became a 3d digital model of an outdoor lamp that creates both functionallight and moodlight.
Generella riktlinjer vid distribuerad Scrum
Today many companies are global and can exist all over the world. It is more common that projects are conducted in different locations, from various cities in a country to nations in different parts of the world. To manage projects both traditional practices such as the Waterfall method and new flexible methods known as agile methods are used. How is the process affected when a project is distributed, when the team is scattered in different places? This makes it difficult to create a good project, something we will discuss and try to find solutions for.
Nyfikenhet i skolans värld : Vad elever i montessoriklass beskriver som lustfyllt lärande
Studien har genom intervjuer i fokusgrupper undersökt vad elever i montessoriklass erfar som lustfyllt i sin lärmiljö. Elevernas svar har satts i relation till den forskning som finns kring motivation och framgångsfaktorer för lärande samt till montessoripedagogiken.De teorier som studien utgår ifrån är olika motivationsteorier, teorier relaterade till motivation samt montessoripedagogik. Även framgångsfaktorer för lärande beskrivs. Tillvägagångssättet i analysen av fokusgruppsintervjuerna har inspirerats av fenomenografisk metodansats. De två forskningsfrågor som studien ger svar på är vad elever på mellanstadiet och högstadiet, i de undersökta montessoriklasserna, framför som orsaker till att de känner nyfikenhet att lära sig mer i skolan, samt vilka av dessa faktorer som är kopplade till montessoripedagogikens principer, och om de går att överföra till all undervisning. Resultatet av studien visar att eleverna pekar ut läraren som viktig för huruvida de ska känna nyfikenhet och lust i lärandet.
Att undervisa kring miljö och hållbar utveckling - Hur förhåller sig läroböckerna i samhällskunskap, historia och geografi till Lpf94 och de nationella kursplanerna?
Daily citizens are informed by the media about the environment and the climate changes. The schools purpose is to educate students according to events that are of current interest and take place in present time. According to Swedish curriculum, Lpf94, all Swedish education should include and discuss the problems surrounding durable development. The purpose of the study is to se how the textbooks in History, Social studies and Geography and their contents meet the demands of the curriculum. The study shows that only the textbooks in geography meets the demands that the curriculums have on durable development.
Grundvattenpåverkan kring järnvägstunnlar i berg
Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.

Pedagogers anmälningsplikt : - att anmäla barn som far illa
AbstractIn 1998 the Swedish legislation was sharpened, and active educationalists were legally bound to report any suspicion of child maltreatment. Nevertheless, there are a number of unrecorded cases of maltreated children, and research reveals that less than half of these children are reported to social services (Olsson, 2001). The purpose of the present study was to illustrate the problems with the mandatory reports in schools, as well as to study how educationalists proceed when they suspect that a child is maltreated. The method consisted of semi-structured interviews with five educationalists. The results revealed complex problems regarding educationalists mandatory reports.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.
Analys av turbulensmodeller för CFD
This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.
Användbarhetsutvärdering av en grafiskt visualiserad patientjournal
First-year students at Linköping University have developed a prototype that graphically visualizes a medical record in a new way. The customer of that project was the Department of Biomedical Engineering at Linköping University. They now want a usability evaluation to be performed of the prototype. The prototype is to be used by employees in the public health care and is supposed to be used on a small portable unit with a multi-touch interface. For this reason the prototype will be used as a complement to existing systems when the users work near the patients.
