Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..

Handling of animals during anaesthesia is an important field in the profession as a veterinary nurse and in which intubation is an essential part. Hence, adequate knowledge is necessary for the welfare of the animal. The objective of this literature study was to make it useful and trustworthy for veterinary nurses. It is intended to describe and summarize existing scientificity with its benefits and disadvantages within the different areas of intubation techniques and alternative methods of inhalation anaesthetic supplementation for general anaesthesia in rabbits. Endotracheal intubation in rabbits can be complicated and technically demanding due to the anatomy of the oropharynx including the narrowness of this structure, a relatively large tongue, large incisors and a limited mobility of the temperomandibular joint. The obstructed visualization of larynx and the rabbit?s tendency to develop laryngospasm contributes to the difficulty of intubation. Rabbits are susceptible to tracheal injury and multiple intubation attempts can cause tracheal lesions due to repeated damage to the tracheal mucous membrane, although damage can occur after a single intubation attempt as well. An ETT (endotracheal tube) with or without a cuff can be used during orotracheal intubation in rabbits.

In the following study I probe the social world of hard-rock music. By conducting interviews with four young male enthusiasts of this music I try to develop a general picture of this social world, as well as of the basic elements on which this particular subculture is constructed. The identity of a hard-rocker is based upon a number of factors beyond just a preference for that music. Throughout the interviews I encountered many implicit norms that one must followed in order to be able to see oneself as a true hard-rocker. I also found that from the respondents? perspective, the mainstream culture has, throughout the history of metal music, used various ways to counter the spreading of this genre.

Försvarsmakten beskriver i Arméns utvecklingsplan 2010-2020 att tre dygns uthållighet på taktisknivå inte är tillräckligt utan bör vara mer flexibelt så att den även passar mindre enheter som skall kunna verka över stora avstånd utan möjlighet till egen logistik. Syftet med uppsatsen är att utreda vad trovärdig uthållighet är. Att utreda om tre dygns uthållighet på taktisk nivå är tillräckligt eller om denna bör utökas till mer än tre dygn. I uppsatsen beskrivs vad som står skrivet i olika dokument från Försvarsmakten vilka styr uthålligheten. Det beskrivs även hur Försvarsmakten avser att uthålligheten skall se ut i framtiden.

The rise in prevalence and severity of obesity and related diseases imposes increasing costs on society. The objective of this thesis is to discuss and estimate the possible effects of a so-called fat tax as a tool for minimizing these costs. Two alternatives for differentiation of the value-added tax (VAT) on food are compared. The first alternative is an increase of the VAT levied on food containing saturated fatty acids. The second alternative is a subsidy on fruit and vegetables in the form of a VAT at zero percent, instead of today?s twelve percent.

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

The Swedish processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Epizootier som drabbat marina däggdjur och lett till storskaliga dödsfall har uppmärksammats runt om i världen de senaste decennierna. Höga halter av persistenta miljökontaminanter såsom DDT (diklordifenyltrikloretan) och PCB (polyklorerade bifenyler) har uppmätts hos djur som drabbats. Detta har lett till tankar om att miljökontaminanter, i den nivå de finns i våra akvatiska ekosystem idag, kan vara en bidragande orsak till den ökade mottagligheten för infektioner och den ökade mortaliteten hos marina däggdjur. I denna litteraturstudie sammanställs resultaten från försök, både på laboratoriedjur och marina däggdjur, som tyder på att kontaminanter med fokus på PCB kan orsaka immunosuppression och därmed vara en bakomliggande orsak till allvarligheten i dessa epizootier. Resultat från studier visar på att PCB kan orsaka immunosuppression genom att ge nedsatt proliferativt svar hos T-lymfocyter under stimulering med mitogener, minskad aktivitet hos NK-celler, nedsatt antikroppsproduktion, minskad antigen-specifik proliferation och minskat DTH (delayed-type hypersensitivity) svar.
