Optimalt ekologiskt : att gestalta praktfulla parker som kan skötas på ett hållbart sätt

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

Artrika vägkanter - hur påverkas de av slåtter och underhållsdikning?

ABSTRACT This study is an exam work at the Department of Ecology at the Swedish Agricultural University, Ultuna, Uppsala. The field work was performed in the counties of Uppsala and Västmanland. Grassland areas, exposed to annual mowing, are known to host a variety of rare and red-listed vascular species. The area of these grassland are, however, decreasing in the landscape due to modern farming. The fact that roadside verges maintain regular mowing has proven to be a successful concept for many rare vascular plant species in this habitat. Vascular plants along roadside verges at the State road network were inventoried due to a government mandate during 1995 and 1996. As a result ?Species rich roadsides? were pointed out.

Luftutsläpp från järnmalmsproduktion : - Strategier för systematisk luftkvalitetsmätning

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Ledare & team utan rätt förutsättningar kan aldrig nå maximal framgång : En studie om tre olika produktionsverksamheter inom Volvo Group

This thesis has been conducted at Volvo Bussar ABunder a period of ten weeks. Within the organizationVolvo, the work is conducted with leaders and teamson every level; from production to top management.They have three tasks, besides executing their dailywork, they are expected to actively work on improvingtheir individual work as well as themselves as persons.The two latter are future value adding activities for theorganization. When doing so, however, it has beennoticed that they often lose the grasp of their dailywork. The question that consequently arises is whythis happens. Is it because of lack of time or it isbecause the co-workers do not have the competenceand simply do not know how they are to execute thethree tasks? Or, is it because the motivation to executethe three tasks is not enough? With this in regard, thestatement of issues for this bachelor thesis were thefollowing: how can the conditions for leaders and theteam be improved, in order for them to execute thesethree tasks.To find out why the execution of these threeassigments did not always succeed, the decision wastaken to conduct a survey and interview study in reallife and at the plants.

En jämförelse mellan får- och nötkreatursbetade hagmarker med avseende på populationsstorlek samt artsammansättning hos dagfjärilar och örter

Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.

Plan för multifunktionella buffertzoner längs Vramsån påMalörten AB : s jordbruksfastigheter

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

vindkraftens påverkan på elkvaliten

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

GIS för fastighetsrättsliga frågor inom energibranschen

The purpose with the work is to study Fortums activities with hydro power plants, dams and reservoirs mainly in a premise jurisdictional perspective and to show how GIS would be a helpful tool for the future.A great deal of the information that the Generation Hydro-division at Fortum are managing have a spatial element. That means that it is possible to spatially join this information to a geographical polygon, line or point. This information is today gathered from several different sources, such as files, paper maps and digital data of several kinds. A Geographic Information System (GIS), as and aid besides the ordinary tools should be an effective support in the everyday work with questions of a premise jurisdictional nature.The goal of this work is to account for how to organize, present and analyse geographic information. We will show how to link from the map to traditional tools such as calculation- and register programs.
