Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

The cat has become a popular pet. To secure a prosperous cat-human relationship, the cat owner has to understand what kind of animal the cat is and what requirements need to be fulfilled. The purpose of this literature review is to summarize kittens? needs of socialization, anthelmintics, nutrition, vaccination and gonadectomy, until the age of six months and to give the cat owner information on how to care for the cat during this period. Articles were search for in ScienceDirect, Primo and Scopus.

At seed-growing the aim is to produce a commodity with high germination capacity, good soundness and purity, and also slight admixture of seeds from other species. The capacity of germination and the vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases, growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can be due to the fact that the seeds are in rest of germination, i.e.

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Methadone is frequently used as an analgesic drug for dogs although there are very few studies describing the pharmacokinetics of methadone in this species. In man methadone has a long half-life and there are considerable differences in pharmacokinetics between individuals. The dose interval is lengthened when the drug is used fore longer periods of time due to prolonged half-life. Therefore the drug dose must be adjusted individually. The purpose of this study was to study the fundamental pharmacokinetics of methadone in dogs, and to find an optimal drug dosage.

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.

Syftet med denna studie är uppdelat i två aspekter. För det första avser vi bidra till kunskapsutveckling genom att observera och presentera vilka incitament som kan finnas bakom kommunicerande av intellektuellt kapital (IK) utifrån IT-företags rapportering av IK genom årsredovisningen. För det andra avser vi att genom vår studie ge ett metodbidrag till forskningen på IK-området genom att visa hur kategorisering med hjälp av ett flerdimensionellt analysverktyg kan användas, tillsammans med olika teoretiska perspektiv, för att analysera hur incitament för rapportering av IK reflekteras i IT-företags årsredovisningar.Studien har utförts genom att empiriskt material från årsredovisningar har kategoriserats utifrån en nyskapad modell bestående av fyra huvudkategorier med vardera fyra underkategorier. Modellen är starkt influerad av Sveiby (1997) och Meritum Project (2002) men utgörs totalt sett av en syntes av ett antal olika modeller och teorier från forskare inom IK-området, med vissa externa influenser. Det kategoriserade empiriska materialet har sedan analyserats utifrån fyra teoretiska analysperspektiv.

The Apollo butterfly, Parnassius apollo, is categorized as Near Threatened (NT) in IUCN Red List. Today in Sweden it is found only in strongly fragmentized populations. In the county of Stockholm, P. apollo exists exclusively in some islands of the archipelago and with one mainland population in Stora Vika. This study has the purpose of expanding the knowledge of the local conditions for the butterfly in the south parts of the county of Stockholm and thereby contributes to a sustainable land management that can preserve the Apollo butterfly.A comparative study was done between areas where the butterfly today have: a stable population (Stora Vika, Utö and Ålö), has disappeared (Muskö and Yxlö) or is strongly declining (north part of Ornö).

The Northern Raccoon (Procyon lotor) belongs to the Carnivore-family and is a species endemic to North America. Every year hundreds of orphaned raccoon cubs are admitted into the Wildlife Rehabilitation Center of Minnesota (WRCM), a non-profit organization where all injured or orphaned wild animals are admitted and receive quality health care with the goal of being released out into the wild. The WRCM routinely vaccinate all of the admitted raccoon cubs with a killed feline panleucopenia vaccine, but despite this there are outbreaks of parvovirus infection every year where up to 50% of the admitted cubs have been euthanized or died. The objective of this study was to determine whether vaccinating the admitted raccoon kits has any significant protective effect to developing clinical parvoviral disease. A single-blinded cohort study was designed with two parallel, independent groups. One group was given a dose of killed feline parvovirus vaccine at admission, and the other group was not given any vaccination at all. Assignment to the vaccinated or unvaccinated group was on a per-litter basis and done randomly by drawing lots out of a box.

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

Det svenska språket har ett komplicerat system för att manifestera bestämdhet till skillnad från de flesta andra språk. Detta för med sig att bestämdhet är ett av de områden inom svenskan som orsakar stora svårigheter för dem som önskar tillägna sig svenskan som ett andraspråk. Ett svårt fall gäller substantivets bestämdhet efter alla. Svenskspråkiga väljer en lämplig böjningsform omedvetet. Däremot är det svårt att förklara varför man formulerar sig så som man gör.Inom forskningen på området är det fortfarande inte fullständigt klarlagt hur bestämdhet styrs efter alla.

Arbetet har gått ut på att utveckla en lavintransceiver.En transceiver är en sändare samt mottagare i sammaenhet och är ungefär lika stor som två medelstora mobiltelefoner.Gemensamt för alla lavintransceivers är att desänder ut och kan ta emot en signal på 457 kHz som ärlagstadgad internationell standardfrekvens. Transceiversanvänds vid skidåkning utanför preparerade backar föratt kunna söka efter lavinoffer och bör bäras av var ochen i en grupp. Hamnar en eller ett par personer i gruppeni en lavin kan de resterande som klarat sig ställa om sinasändare på sökning och spåra offret i tid.Mitt skidintresse och allvaret kring laviner lockademig till att undersöka och utveckla denna utrustning.Efter flera samtal med både vana användare och personersom inte sett en transceiver ifrågasattes hela konceptetoch ny teknik som kan ersätta den gamla söktes.Många intressanta tekniker granskades och förkastadespå grund av att de inte skulle kunna ersätta den befintliga,teknikerna var för outvecklade eller passade inte i sammanhanget.När ingen teknik var överlägsen den befintliga sågranskades dagens transceivers. Ett antal punkter visadesig vara värda att se över. Ergonomi, gränssnitt och formblev huvudfokus, det vill säga hela konceptet.
