The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.

Företag blir alltmer multinationella och detta har gjort dem beroende av en mer globaliserad syn på företagsstyrning. Därför fokuserar företag idag på att hitta förmågor och talanger som kan leda under globala förhållanden. Denna studie behandlar ämnet Global Talent Management (GTM), en personalplaneringsprocess som syftar till att skapa en grupp medarbetare med särskild god prestationsförmåga och hög potential, för att vidare utveckla dessa till att förverkliga företagets strategier. Prestationsmätning har använts sedan länge av företag men när det kommer till potential finns svårigheter i att kvantifiera detta då det är något som lätt blir subjektivt. Otydligheten som detta problem ger speglar sig även i hur transparenta företagen är med processerna av GTM i organisationen.Syftet med denna studie blir därför att kartlägga hur svenska företag använder GTM med särskilt fokus på variabeln potential och hur transparenta de är med sitt arbete i organisationen Syftet hoppas infrias genom att studera fyra multinationella företag med rötter inom den svenska servicesektorn.

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

Marknaden för flygmotorunderhåll har blivit allt mer konkurrensutsatt sedan nya aktörer börjat ta marknadsandelar. Det kärvare marknadsklimatet har främst drabbat de små fristående underhållsleverantörerna. En av dessa små fristående underhållsleverantörer är Volvo Aero Corporation, VAC, i Trollhättan. Ett problem vid flygmotorunderhåll är behovet av reservmotorer. Kapitalkostnaden för inköp av reservmotorer är mycket hög, samtidigt som bristkostnaderna också är mycket höga.

The intention of this thesis is, from a basic statistical viewpoint, to capture the relationship between the price of electricity and a sample of factors influencing the price. The thesis also aims at investigating whether knowledge about the relationship is useful when investing on Nord Pool. Tested factors are temperature, import, price of emission rights as well as a number of hydrological factors. The investigated period stretches from year 2000 until week 32 year 2007. The relevance of each factor was also evaluated yearly as well as for shorter periods in order to get a more comprehensive view of the relationship.

The aim of this paper was to investigate whether or not it is possible to keep bottlenose dolphins and killer whales in captivity while maintaining good animal welfare. Today, many zoos and aquariums claim that their primary function is to conserve species and educate people about conservation and threatened species. The keeping of wild animals is justified by conservation programs and by the information spread to the zoo visitors. This does however not seem to be the case for marine mammals such as bottlenose dolphins (Tursiops sp.) and killer whales (Oricnus orca) since these species are not threatened in the wild and neither of them are listed as threatened in IUCN's Red List. Bottlenose dolphins and killer whales are entirely aquatic carnivores and are distributed in all coastal and pelagic waters from the Arctic ice in the north to the Antarctic ice in the south.

The company Pilotfish has developed the system MIVEO which is used by car-sharing to wirelessly monitor, book or otherwise manage a fleet of cars. In a car pool the system has three different types of users with varying degrees of eligibility. These are end users, administrative and service personnel. We have chosen to focus on opportunities to streamline the administrator and service personnel work with a mobile service, as these users of MIVEO often are movable and mobile. From this position we have in the study attempted to answer the following question: How can mobile services used to streamline administrative tasks? This study is about developing a mobile application that will contain the same features as the existing system, but must be mobile suit.

This report treats whether it is viable to invest in solar heating to heat the therapy pool at Östersunds Rehabcentrum. The rehab center is owned by the county council of Jämtland and is located on Solliden in Östersund city. The solar heating where supposed to be a complement to the district heating that was heating the pool in the current situation. Later, it however showed that this was not the case. The pool is currently being heated by a radiator circuit that is being heated by the district heating.

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.
