In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

The aim of this essay is to examine the handling of plastic waste on a local level in the three municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of guidance within the theory of Multi-level Governance. By applying the EU directive 2019/904, about disposable plastic, and examining the global plastic problem, the efforts to promote sustainable use, and recycling of plastic, is analyzed. The method involves a qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes the base of the study.

Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.

Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.

The economic conditions for Swedish dairy farmers are constantly changing. The numbers of producers are declining and the economic conditions for dairy production are weakening debilitating. To improve the economic situation for a farm a hired contractor is a possible solution since previous studies show that machinery cooperation may be beneficial for the farmers. The aim of this study is to examine the possibility for farmers to cut costs by hiring a contractor for harvesting silage. A comparison between using own machinery and hire a contractor is the starting point of this study. Another aim is to discuss the farmer?s decision process when achieving today?s situation and to determinate what factors affect their decisions. The study is based on cases selected from four farms that today have chosen not to or only to some extent, hire a contractor for harvesting silage.

It has been shown that moose can affect plant community composition and structure. Selective browsing with other damages of large herbivores on tree species with different tolerance to disturbance could reshape the tree layer in both managed and natural forests. Rowan Sorbus aucuparia is widely distributed throughout Sweden and Europe. Research has shown that browsing by moose may prevent rowan from reaching browsing safe heights. The goal has been formulated that, where rowan is indigenous, it should have a good competition status and be able to reach tree level.

Inom industrin används olika testmetoder för att uppnå hög kvalitet i mjukvarukontrollerade system. Kvalitetskraven är särskilt höga för säkerhetskritiska system t.ex. styr- och reglersystem i fordon. I det här examensarbetet används två analysmetoder (Fault Mode and Effects Analysis och Fault Tree Analysis) för att ta fram ett nytt säkerhetstest för ett broms- och växlingssystem som Scania tillverkar. Det studeras även hur formella metoder kan användas för att ytterligare öka kvalitet ochh tillförlitlighet.

The purpose of this Masters thesis is to investigate the role of link collections in Swedish public libraries mediation of Internet resources. The study is focusing on the effects on the contents and the structure in the link collections when the target group is immigrant users. This is done through literature studies completed with an examination of two link collections containing multi-cultural and multi-lingual material and qualitative interviews with the two librarians who are in charge of the collections. The major questions raised in this study are: What function do the link collections have for the public libraries? What is the difference in working with traditional, printed material compared to the work with Internet resources? And how are the selection of Internet resources and the structure of the link collections affected when the collection is intended for immigrant users? The main results are that link collections in public libraries can give a concrete form to political guidelines.

Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions. The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.

Det här är ett examensarbete som är utfört på uppdrag av Meal Planning Concepts AB. Målet var att utveckla en native multi-plattformsapplikation till smartphones och surfplattor som skulle fungera på Android och iOS och dela databas med deras nuvarande webbsystem. Funktionaliteten skulle vara baserad på den som fanns på deras webbsida. Applikationen utvecklades i MoSync som är ett ramverk som klarar utveckling till multiplattform. Examensarbetet gick också ut på att utvärdera MoSync under projektetsgång och presentera andra liknande verktyg och hur de förhöll sig till MoSync.

The purpose of this paper is to investigate and to analyse didactic considerations and decisions made by pre-school teachers in the context of a multi-cultural pedagogical environment.The basic theoretical perspective is social constructivism, but notions from Donald A. Schön and John Dewey's theories of thinking and reflection have also informed the study; even Hans Lorentz' definition of a multi-cultural pedagogical environment has been employed as an analytic tool.The empirical study consists of a qualitative field study at a pre-school, where participatory observation and a group interview have been used in order to collect data. Those who participated were teachers at the pre-school.The results of the study, when analysed in accordance with the method, shows mainly three things. First of all that the teachers at the pre-school, in their didactic considerations, make use of the following methods of knowledge formation: knowledge-in-practice, reflection-in-practice, reflection on practice, reflection on knowledge-in-practice, and reflection on reflection-in-practice. Secondly, that no reflection particularly on the learning conditions in a multi-cultural pedagogical environment takes place.

The thesis first objective was to develop field instructions for forest planning of native forests in Andean Patagonia, and the second objective was to test the plan on an actual property in the area. The thesis was limited to studies in the province of Rio Negro. Today, there are no official forest management plans for native forests in the Argentinean province of Rio Negro; thus, there is an obvious need for an official forest management plan with clear guidelines. To be granted permission to manage, i.e. through thinning, the native forests on a property it is required to have a forest management plan that is approved by the Forestry Board in the province in question (Thill, B.

During the period 1952-2008, real prices of wood before taxes and charges declined. However, the actual net income has not changed by the same percentage as the price list, because taxation, driving costs and the ability to make deductions has changed. This report considers the inflation by using the Swedish consumer price index. Net income refers to the remaining income when relevant costs, taxes and fees have been paid.The purpose of this study was to examine how the private forest owner's real net income has evolved over the period 1952-2008 for three categories of forest owners. These three categories are1.

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.
