On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization. It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared. During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.

This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality. In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

What are the basic thoughts formulated in the Heraclitean fragments? A cosmology, a philosophy of nature, the idea that all can be reduced to a single substance? There is always a risk that Heraclitus is fitted into a thought pattern he doesn?t belong to, if we ? from our present horizon ? focus on continuity in an attempt to frame his thinking as part of an overall progress, running from the so-called pre-Socratics to Aristotle, in the history of philosophy. If we picture the dawn of Western civilization as an early development of scientific thinking, built on a gradual and continuous growth of knowledge, we will easily go astray as we try to discover the Greek origins of philosophy. Assuming, for example, that the readings of Heraclitus as a natural philosopher have come to a dead end, can we approach the fragments from a different angle?The aim of this paper is not to give a systematized reading of all the remaining fragments of Heraclitus, but neither to necessarily contradict the various interpretations that emphasise how these shattered remains reflect a coherent philosophy.

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.

The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C). The program is written in Visual Basic .NET and I choused that program language because it is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.

Studiens målsättning var att utvärdera kvalitén hos hingstsperma selekterad med hjälp av Single Layer Centrifugation (SLC), med huvudsyftet att studera den mitokondriella membranpotentialen (??m) och förekomsten av reaktiva syreföreningar (ROS) hos hingstspermier före och efter SLC. Ett insemineringsförsök med SLC selekterad och rutinspädd sperma genomfördes även på ett litet antal ston, men inga slutsatser kunde dras av resultaten. Humanstudier har visat att spermier med låg ??m mer frekvent har återfunnits hos män med fertilitetsproblem. Mätning av ??m har gjorts genom att tillsätta den lipofila JC-1, vilket i både studier på både humana- och ekvina spermier har visat sig vara en känslig metod för att särskilja spermier med låg respektive hög ??m.
