Många arter påverkas idag negativt av skogsbruket. Detta visar sig dels i ett växande antal arter på den svenska Rödlistan. I Norrbottens län är idag närmare 500 skogslevande arter rödlistade, och dessa är fördelade över flera olika organismgrupper. Det stora antalet rödlistade arter i skog innebär att det är svårt att direkt utifrån Rödlistan utforma effektiva naturvårdsåtgärder samt generell hänsyn inom skogsbruket. Genom att sammanställa och strukturera information om de rödlistade arternas krav på livsmiljö och hotsituation kan Rödlistan som verktyg utvecklas.

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

Beacon AB has been producing Gobos for some time. A Gobo is a small round sheet used in projectors almost like a slide. It is used mostly in the commercial and entertainment business. Today these Gobos are created by using a film (also called mask). A digital exposure machine called LIOS has been developed to make it possible to create Gobos using direct exposure.

One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

The problem with keeping horses with to little social contact has come to attention in a new regulation that comes into effect august 1st 2009. It states that horses? need of social contact has to be accommodated. That?s why it feels important to try to survey the horse owners? awareness about the regulation and its present fulfillment.

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

EU-kommissionen har satt upp som mål att få ett unisont redovisningsspråk för alla företag i Europa. Därför har kommissionen antagit de regler och standarder som den London baserade organisationen International Accounting Standards Board arbetat fram.Studien syftar till att undersöka och utvärdera hur ett antal slumpvis utvalda bolag, som i huvudsak agerar i fastighetsbranschen, efterlever IFRS regelverk IAS 40 gällande förvaltningsfastigheter.Vi har i vårt arbete använt oss av en kvantitativ metod. Underlaget för empirin är hämtat från årsredovisningar från 2009 och är insamlade från företagens egna hemsidor som vi har navigerat oss fram till via Nasdaq OMX Nordic. Dessa har vi granskat och resultatet har redovisats i tabellform.Resultaten visar att det fortfarande finns mycket att arbeta med när det gäller efterlevnad av standarderna. Den största skillnaden fanns hos de Danska företagen när det gäller att lämna vissa upplysningar och kan vara värd att följa upp i en framtida studie.

Title: Management control of facility efficiency in municipalities - A case study of Halmstad municipalityLevel: BachelorSeminar date: 2012-05-31Authors: Markus Nilsson & Sara MattssonAdvisor: Sven-Ola CarlssonKey words: Control management in municipality, facility efficiency, management by objectives, internal rents and incentivesBackground: The public sector owns and manages a large property portfolio and in the municipalities, the properties are always a big cost item. Because of the outside world changes and the public interest, the properties should be used as efficiently as possible.Purpose: The purpose of this paper is to describe how control management of facilities looks like a municipality. The paper also seeks to explain how employees work to make the facilities more efficient in a municipality.Methodology: The authors use a qualitative method with open interviews.Theoretical perspectives: The choice of theory was made with the field of management control and facility efficiency in mind. The theory therefore includes management by objectives, internal rents and reward systems, motivation and communication within organizations.Empirical foundation: The organization has undergone a reorganization 2010/2011. There are no clear incentives to reduce facility costs.

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.
