Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

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..

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..

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..

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.

To reach objectives within EU?s Habitatdirective and the national environmental objectives, more information about semi-natural pastures is required. The expression semi-natural pasture is used for pastures that during the latest time are uncultivated and unfertilized. Semi-natural pastures are important in many respects for example to conserve the biodiversity and for our cultural history. The aim of my study was to compile and calculate the area of semi-natural pastures by use existing sources of information.

This study is essentially based on my own questions concerning contemporary playgrounds. Why are they so unimaginative? What do the children say about them? Is it possible to create playgrounds less constructed, and with more natural elements? This report starts with references to literature studies, personal references and my personal view, and ends with a suggestion for a physical solution for an actual day care centre. The aim is to learn more about how the natural environment affects children, the importance of playing, and try to use this knowledge in a design of a day care centre. My main theme can be summarized in the following question: Why is natural elements in playgrounds considered to be healthy for children? I wanted to create a playground with natural characteristics which I myself would have appreciated as a child.

Objective: Our purpose with this study is to demonstrate the impact of natural disasters on banks' share prices.Method: Quantitative survey method, an event study.Conclusion: There is no association or a very weak correlation in this study between natural disasters and the Swedish banks' share prices..

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

 The objective of this thesis is to examine the difference in workability in fresh concrete, when crushed fine aggregate replaces natural gravel. The shape of the fine aggregate,  packing and flow of six crushed material and three natural materials will be determined by easy studies, the results will be compared with a slump cone test..

The purpose of this essay is to find an answer to whether the methodology used by the Naturskolan conduces to learning and also if the Naturskolan, as a method of its own, leads to an increased interest in natural science for the pupils participating in the classes at the Naturskolan.The method which has been used to reach the results of the study is a quantitative opinion poll. The results reached through the study has been compared to previous research in the subject. Deeper studies were made to examine however the interest of the pupils was influenced by their visit at the Naturskolan.The results of the study show an increase of interest in natural science after visiting the Naturskolan. It also shows that the teachers? interest in natural science and outdoor pedagogy has increased by the visit at the Naturskolan.Through this study we came to the conclusion that the Naturskolan is a good method to learning..

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.
