Nya trädgårdsväxter för ett allt varmare Sverige
The aim with this work has been to examine the climate changes and what these has meant, and will mean during the present century, for plants that have not been hardy in Sweden. A lot of new species can probably be grown today in Sweden's most southern parts, due to an increase in the average annual temperature by 1?C. There is a need of information about these new species and their hardiness. The insufficient information about the subject has been the background to this work.
Högskolestudenters biblioteksanvändande: En intervjuundersökning av några storanvändare
The purpose of this master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.
Barnets bästa i skolan
The United Nations Convention on the Rights of the Child (UNCRC) was ratified by Sweden in 1990. Among its principles is devotion to the best interests of the child (article 3). This principle is hard to define, and it is difficult to find studies on how children express themselves about how the convention should be realized. The Swedish government wants local councils to introduce routines that follow the proposed rights. The Swedish school system is an important arena where UNCRC?s rights can be put into practice.
Effekten av rollkur på hästens rörelsemönster och välfärd
This essay intends to provide an understanding of the developments in the right of public access and recreational activities in the forests of Sweden, and which factors and prerequisites that have affected this development. The forest and its history, along with recreational development has in many ways shaped today?s rights of public access, but there is also an age-old tradition of public access that has affected how we have used the forest, and that also has enabled the development of outdoor recreation. Many are unaware of this, which causes misunderstanding to appear around the rights of public access and how it is supposed to be used.The essay opens with historical descriptions of public access, the Swedish forest and outdoor recreation, to thereby provide a picture of how these three fields have influenced each other over the centuries. This is followed by a description of the current access rights and the problems associated with those, and a description of other countries' equivalent of the right of public access.

The bioavailability of soluble oxalates in stir-fried silver beet leaves
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Svamparnas roller i svenska barrskogsekosystem : hur ser kunskapsläget ut hos några olika grupper människor?
Fungi are everywhere around us and recently, there has been
an increased interest in their role and importance in the forest.
The fungi have several strategies to acquire energy and nutrition; one example is a mutual symbiosis with trees and plants - another being dissolving organic materials.
Attempts have been made to better understand the circulation of nutrition in coniferous forests, and how fungi cooperate.
Trees and plants have adapted with mycorrhizae and are now interdependent which is important to consider in forestry.
A great number of fungi depend on dead wood and old trees to set fruiting bodies and spread further. These fungi also create environments for other species, such as birds and insects.
The vegetation of a forest is determined by a series of factors; tree species, how old the forest is, soil type, as well as the ability of the fungal spores to spread and establish. Furthermore, in determining vegetation, the fungi?s ability to compete in the soil matters. These factors are nearly unexplored.
Researching fungi knowledge and interest, a survey was distributed to five groups of people.
The groups included forest owners, high school teachers, high school students, senior citizens, and a fifth group - ?o he ? - consisting of people of mixed ages and backgrounds.

Design av utomhusträdgård i Dubai :
To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation.
It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.
Avvikelser i energiprestanda
Calculated and measured energy in residential buildings is going to differ. The reason to this may be due to many factors. In this study there is a study on how these factors affect the energy use in a building. To get an insight in what defines energy, there is first a description of energy supply both worldwide and used in Sweden, followed by a description of the energy balance. In this study energy will be studied in residential buildings only.
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.
Controlled traffic for grass silage production : an economic evaluation for dairy farmers
The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic
lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower
clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.
Etnisk diskriminering i rekryteringssituationer : Hur skyddet ser ut i Sverige och vad arbetsgivare kan göra för att förhindra diskriminerande rekryteringar
Ethnic discrimination is still a problem in the Swedish employment market. The Ombudsman against Ethnic Discrimination received 154 complaints relating to discrimination due to ethnicity in the working life in 2012. In addition, reported unemployment rates in Sweden differ markedly between native-born and foreign-born. The purpose of this paper is to investigate how protection against ethnic discrimination in recruitment looks like in Sweden and describe different methods an employer may use to prevent that ethnic discrimination occurs in recruitment situations. The first and second issue of the essay concern what protection there is in Sweden against ethnic discrimination in recruitment situations, based on international and national law. The traditional legal dogmatic method, which describes the valid law, is used in these sections.

Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?
Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.
