Miljö- och Handelsgåtan : Intellektuella egendomsrätter och dess implikationer i en globaliserad verklighet
This paper seeks to discern the political factors that determine the results of negotiations in international cooperation. On the one hand, it makes a contribution to the broader theoretical debate on international regimes by combining regime theory and theories on globalisation into an integrated framework for the analysis of international policy results, or in this case treaties (theoretical objective). More generally, globalisation theory will help us understand why it has become important to initiate international cooperation, and regime theory to elucidate how these international cooperations emerge. To many observers, it is the large transnational corporations of the rich North, which have done best out of free trade. Through the huge influence they wield over governments at the WTO (World Trade Organisation), these corporations have won the freedom to move around the globe without restriction, making use of cheap labour, and locating wherever they can best tap into the largest and most lucrative markets.
Praktisk Fysik : Laborationernas och demonstrationernas vara eller inte vara.
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
Om associationer till vatten
This paper is intended to provide a picture of which associations water can wake in the human
mind from the perspectives of garden history as well as from that of environmental
psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a
basis for discussion and as a starting point for different forms of design work in landscape
architecture. The historical perspective emphasizes the importance of water as a condition for
the emergence of gardens and in a wider perspective the importance of water in early cultures.
Also, I describe a picture of how water has been used throughout the history of gardens from
early Egypt to the baroque era. The garden history analyzed from an art historical perspective
gives a picture of human associations to water, and the history behind these associations is
presented. As a compliment to the art history approach, I have chosen to highlight our
associations with water from the perspectives of environmental psychology and evolutionary
science.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Double integrating spheres: A method for assessment of optical properties of biological tissues
The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.
Upprördhetens betydelser : Diskursanalys av en känslosam riksdagsdebatt
Today there are many students with behavioral and developmental disorders in schools. One of these disorders is ADHD. The medical designation ADHD stands for Attention Deficit Hyperactivity Disorder. I have chosen to research how two students with ADHD can be included in a fifth grade classroom.This research paper addresses the issues surrounding the student?s day-to-day life with a focus on the classroom.
Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar
During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003.
Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
Hur påverkas ens uppväxt och vuxenliv av att man växt upp i ett familjehem? : en kvalitativ intervjustudie där fyra vuxna tidigare familjehemsplacerade reflekterar över de erfarenheter och upplevelser placeringen medfört
The purpose of this study was to give a picture of how some adults, who earlier was placed in foster homecare, experience that their childhood have affected them during their life. I also wanted to see how the relationship to the biological family has been and developed during the placement. The study has also purposed to receive a deeper knowledge of how it could be to grow up in foster care. To make the purpose of this study complete I chose to use qualitative interviews as a research method. Four adults who earlier were placed in foster homecare have participated in this study.
Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd
Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT.
The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.
Sjuksköterskors upplevelser av möten med patienter från andra kulturer och deras närstående : en intervjustudie om smärta
Background: Many Swedish inhabitants origin from different countries with different cultures that may show pain in other ways than Swedes. The Swedish law stress that nursing care should be done individually according to the patient's capabilities and needs. Aim and Method: The aim of this study was to describe nurses´ experiences of encounters with patients from other cultures with pain, and also their next of kin. Qualitative interviews were carried out with seven nurses. The interviews were analysed with the starting point in Giger and Davidhizars Transcultural Assessment Model and the six phenomena: communication, space, social organisation, time, environmental control and biological diversity.
Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China
Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.
Nationella adoptioner i Sverige
The purpose of this study was to examine domestic adoptions in Sweden, and also compare the Swedish adoption system to the Canadian adoption system. I wanted to find out why there are so few domestic adoptions in Sweden, and how it has changed over the years. I also wanted to know why there is such a large difference between Sweden and Canada regarding adoptions.I interviewed five social workers to find out what attitudes the social services have regarding adoptions. My other questions were how the childs best interest is considered when a parent wants to place a child in an adoptivefamily, and which parents decide to place their child instead of keeping it.I found that the social services are reluctant to place children in adoptivefamilies because their main goal is to keep biological families intact. In Canada the social services goal is to provide the child with a safe and stable home.There is no longer any stigma surrounding single mothers and well developed welfaresystems enable most to keep their children.
Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
