Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun

Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after Natural disasters and how this is used in the planning of new roads.

Interaktiva, digitala lärresurser : Med underhållning kommer motivation

Earlier research has shown that combining education with entertainment can improve students motivation in school. With this study we aim to learn more about interactive digital learning resources and how they should be designed to entertain and thereby contribute to motivation. We have identified aspects of educational games that also could be considered when developing interactive digital learning resources, to make them more entertaining and motivating. We have chosen to study and evaluate an interactive digital learning resource called ?Grasp the Disaster?, a fictional online adventure created for students in the ages between 13-15.

Katastrofhantering i kapitalets förlovade land : Den amerikanska statens hantering av Dust Bowl och orkanen Katrina

In this thesis, I enquire into how the USA ? our world?s wealthiest and most powerful nation ?  and its federal government has dealt with two of its most severe Natural disasters: the drought and dust storms that plagued the Great Plains during the 1930?s, i.e. the Dust Bowl, and Hurricane Katrina, which made landfall in late August 2005. I attempt to identify differences and similarities and analyze if and, in that case, how the hegemonic politico-economic paradigm affected the federal management of these crises. This comparison is made relevant by the fact that two differing paradigms were at play during these events. In the thirties, President Franklin D. Roosevelt launched his ?New Deal?, a series of counter cyclical measures in line with the Keynesian school of economics, as a response to the overwhelming economic depression as well as the raging drought.

Samspel, etablering och koppling mellan naturgas och biogas

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from Skutskär to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

Volontärarbete : -God gärning eller hobbyverksamhet?

The purpose of this study is to use a qualitative approach to highlight the western involvement in Thai orphanages and, on basis of Western moral development workers and volunteers, enlighten how Western colonial heritage can be recreated in the humanitarian economic aid.The study is based on the recent tsunami disaster in 2004 which led to a huge voluntary effort by Western volunteers and organizations who wanted to rebuild the country. Now, seven years after the disaster, the country has recovered well and thanks to a strong turism, and industrial growth, the country has now reached the position of a middle income country with regional power.The study presents a selection of previous ressearch in the area from different critical perspectives. It is a field study based on qualitative interviews with six informants that highlights the individual engagment in humanitarian assistance. Theories based on Post-colonialism and globalization have been used in order to analyze and reach the result of this study..

"Ett lugnt hörn när det är kaos i världen" : en studie om varför barnprogrammet Bolibompa ser ut som det gör under och dagarna efter en katastrof

This study intends to examine why the Swedish children?s programme Bolibompa is produced the way it is during a larger catastrophe. Our intention was to find out how the editorial staff, in the children?s department in the public service television of Sweden (SVT),was handling the Estonia disaster, the September 11 attacks and the Asian Tsunami. To accomplish that, we first had to find out how the children?s programme looked during these catastrophes and also understand how the editorial staff was working with children?s programme during ordinary days.To achieve our purpose we have been interviewing five persons from SVT, who was involved in producing the children?s programme during these three catastrophes.

Tilla?mpning och simulering av naturlig ventilation : Potential fo?r utnyttjande i kontorsrum

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Riskbedömning och naturligt producerade dioxiner

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv

Research suggests that society's vulnerability to Natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Rättigheter och skyldigheter i grundlagarna : I ljuset av den politiska filosofin

The purpose of this essay has been to compare different constitutions, and their outlook on citizenship, rights, obligations and natural duty. This has been done in the light of the political philosophy, in order to give the answer to four questions. These questions are: Which rights and obligations can be seen in the constitutions, and how can it be interpreted. Can there be signs of any political philosophy in the constitutions?  Are there any differences between the constitutions regarding citizenship, rights, obligations and natural duty? If so, what are the differences? Can the rights be seen in a further extent than the obligations in the constitutions?I have conducted a qualitative comparision study and analyzed the political philosophers and made a classification scheme of their views.

Mjölkraskvigors tillväxt på naturbete :

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Entreprenöriellt lärande och entreprenörskap : En studie av hur naturbrukslärare upplever undervisningssättet

This thesis deals with how natural resource teachers in natural resource schools in Sweden work with entrepreneurial learning and entrepreneurship. It is important both for our Government and our agricultural department that entrepreneurship is present in our education. In government´s new reform 2011 for upper secondary schools entrepreneurship is the main theme, but it is not only entrepreneurship as a business company, it is also about entrepreneurship in schools like entrepreneurial capabilities in government´s writ. The purpose of this study is to examine how a number of teachers in natural resource schools are working with entrepreneurial learning and entrepreneurship. I have also asked how the teachers would like to work with these areas.The method I have chosen to use in order to perform this study is qualitative interviews with six natural resource teachers and a pilote interview.The teachers I interviewed are working to provide students with self-knowledge and teaches students to see possibilities and solve problems, which is required for us to create entrepreneurial students and entrepreneurship in education. This is also stressed in several of the literary sources I used..

Övergång till helkrossballast : En studie för Strängbetongfabrikerna i Veddige och Herrljunga

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

Sköldpaddsdammen som en naturlig oas på Mallorca : en fallstudie

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.
