Enaforsholms mountain garden is situated in the western parts of the Swedish province Jämtland. This means a maritime climate. After a donation made by wholesaler A. W. Bergsten the country estate became KSLA property in 1937.

A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.

In the United States, see recommendations for cardiac safety of sports arenas but also to health and fitness facilities. However, this does not exist in Sweden today. Objective: The purpose of this study is to identify the health- and fitness facilities today are equipped with respect to cardiac safety and specifically relating to preparedness for cardiac arrest. Method: Quantitative data are collected and compiled with the help of a questionnaire. The questionnaire contained 19 questions in total.

The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

The aim of this paper is to explain and compare non-compliance of two EU-directives, ?the quality of bathing water? and ?the working time directive?. This study answers the questions: Why didn?t Sweden implement the directive on bathing water quality and the working time directive correctly? Are the reasons for non-compliance the same or different in the two cases? The paper is designed as a case study and with an explanatory attempt we explain why the two directives weren?t implemented correctly in Sweden. The theoretical approach is based on both general- and EU-specific implementation theories.

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.

In this Bachelor thesis I am going to look at attitudes towards political violence in a small town in Sweden in the 1920s. The town I have picked for this study is Kalmar situated on the east coast of Sweden. This study is a micro historic case study. The specific case is a strike at the city?s water and gas plants for higher salary.

AbstractThe customer demand for ecological products has increased in recent years, within the garden industry this mainly concerns herbs and other edible plants. The organic trend is increasing and more people are aware of the environment and want to take responsibility for it through their purchases for their garden as well.In this essay the aim is to investigate customer demand and the possibility of selling organicperennial plants in eight garden centres on the Åland islands and in Gävle/Sandviken. I include two garden centres with an organic profile to get a wider point of view. I investigate the global market for organic perennials and look further into existing certification standards on the Swedish market today.The methods I have been using are interviews and a literature study.The study shows that the experienced demand for organic perennials is small in both of myinvestigated groups. The biggest motivation for starting to sell organic perennials would be to find a supplier of these plants and that more customer would ask for them.

The lack of fresh and clean water today causes severe problems, mostly in developing countries. Waterborne diseases like typhoid, cholera, amoebic dysentery and diarrhea create health problems and deaths among people. There is a need for low cost interventions like household-based water treatment and safe storage (HWTS). Solvatten AB is a Swedish company based in Stockholm. Their product, Solvatten, is a household water treatment unit that can treat water containing viruses, parasites and bacteria.

Cassava (Manihot esculenta Crantz) is a root crop that plays an important role in many households in Africa. It is sometimes called ?Africa´s food insurance?. The advantages with the crop are that cassava is drought-resistant and it can grow in a semi-dry land. It is a perennial crop and does not require much labor.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
