This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

In this work I have tried to reconstruct the forest history within Särna-Idre forest common in northern Dalarna from the 19th century until present time. The Särna-Idre region has been an extensively used landscape for a long time. Pollen which indicates grazing has been found in samples orginating from the 10th century. Early travellers from the 18th and 19th centuries seem to have been passing trough a "used" landscape. Burned forests on naked ground are described as common. Also large areas are mentioned as undisturbed with lots of large trees, snags and dead wood.

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Ulla Isaksson (1916 ? 2000) wrote many novels, often with a woman or several women as protagonists. In Dit du icke vill (?Where Thou Willst Not?) from 1956 she depicts a crisis of faith in a woman, which would not have been successful had she chosen a contemporary setting. She uses an adequate historical framework, the prosecution of witches in Sweden in the 17th century, well documented in reliable sources.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

The elderly care is an area of great importance to women. Women are more often in need of elderly care; they work with the service and provide a majority of the informal service. Research shows that managers? work-related prerequisites are significantly different between the male dominated technical administration and the female dominated care and educational administration. Studies also show that what the highest managerial organisation gives priority to, often permeate the whole organisation.

The recent globalization has to some extent reduced the importance of specific cultures and instead creates a focus on the variation these different cultures provide. Under these circumstances the leader must adapt his leadership to face these new circumstances. The organisations today have to face these new leadership challenges which the global expansion brings. This is a prerequisite for organizations if they want to succeed and be more competitive in a more demanding environment.There are still big differences between the business cultures. There are also differences in the companies? home arena, between groups in the society and all the way down on a family level.

This project is a contribution in the debate of sustainable city planning. The conceptual ideas in this project can be used on many places and are here applyed on the center of Nacka, outside of Stockholm. The essay is based on an entry in the competition Europan 9, advertised by Europan in collaboration with the municipality of Nacka. The theme of the competition is ?sustainable city and public space?. The discussion of the sustainable city is a very wide subject which needs to be narrowed to suite the context of Nacka.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership! This degree thesis is meant to answer the question about which the optimal extension would be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping. Studies in England have shown that skylark reproduction can be greatly improved within conventional fields, at a low cost, by establishing patches of bare ground (skylark plots). Within conventional farming, herbicides can be used in case a weed problem arises due to implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers. The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.
