A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

En studie av en lägerskolas betydelse i lärande för hållbar utveckling I denna uppsats undersöker jag en grupp 11- åriga elevers lärande på en lägerskola samt vad de har för syn på natur- och miljöfrågor. Jag undersöker också om lärandet på en aktuell lägerskola kan utgöra en del av lärandet för hållbar utveckling. Lägerskolans roll som komplement till den ordinarie skolverksamheten diskuteras vidare i uppsatsen. Jag har sökt svar på mina frågor genom att observera en klass med 11- åringar från en medelstor stad under deras vistelse på en lägerskola. Jag har följt upp mina observationer med kvalitativa intervjuer. Undersökningen pekar mot att det är möjligt för unga elever att utveckla en förståelse för abstrakta fenomen som människans påverkan på landskap samt människans samspel med naturresurser. Detta menar jag är en viktig byggsten i lärande för hållbar utveckling.

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

The 1900s saw two incidents of states using their military in civil disorder situations, which resulted in the killing of unarmed citizens. May 14, 1931 in Ådalen, marks a significant part of Swedish history and its view of the use of military force.  On that day, a peaceful protest march escalated, which resulted in live firing by the military stationed there to uphold law and order. This resulted in the deaths of five civilians and the prohibition of the use of military force in incidents of civil disorder. In 1972 in Northern Ireland a similar event took place on January 30, which is commonly known as Bloody Sunday. The Troubles were raging and resulted in protests for civil rights by nationalists.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Sedan 1700-talet har glastillverkning haft en mycket central roll i samhällsutvecklingen i Kalmar och Kronobergs län. Glasbruksverksamhet förknippas med en omfattande föroreningsproblematik. Uppskattningsvis finns det 290 000 m3 jordmassor förorenade av tungmetaller som bly, arsenik och kadmium vilka härrör från glasbrukens verksamhet. De förorenade massorna kan utgöra risk för påverkan på hälsa och miljö.För att möjliggöra en effektiv riskhantering och riskkommunikation krävs kunskap om hur risker med föroreningarna från glasbruk upplevs och vilken informationen om risker som efterfrågas. Syftet med examensarbetet är att undersöka hur allmänheten upplever risker och oro för påverkan på hälsa och miljö från förorenade glasbruksområden samt deras önskemål om information.

Hunting ground graves were distinguished as a separate category during the 1930s.         There is however no clear definition of what a hunting ground grave is. They have been constructed over a large area over a long period of time (200 BC-1200 AD) and their morphology varies.This paper investigates how the archaeologists have discussed the hunting ground graves since they were distinguished as a separate category until today. It investigates what concepts that have been used to define and categorize the graves as a group. It also investigates if the choices of concepts are depending on a broader societal perspective.To find the answers to these questions two surveys have been done.

We have in this field study been researching how social comfort is affected by the work of social services and their collaboration with police, schools and health care within a small village located countryside in the northern part of Sweden. The attribute which sets this village a part from most other small countryside villages is the fact that the crime rate is amongst the lowest in Sweden as well as the social security feeling within the inhabitants are amongst the highest. We traveled 2298 kilometers back and forth to be able to interview professionals and gather empiric material for this study. The method we have used for data collection has been in the form of semi structured interviews. We have used previous research concerning collaboration, social comfort, social discomfort and fear of crime as our aid to analyze our findings with the help of theories regarding different types of communites (gemeinschaft and gesellschaft) invented by Ferdinand Tönnies (2001) and Human Service Organisation by Hasenfeld (1983).

The Internet is a constant source of information about the world and has contributed to the globalization of texts and pictures. A part in the tourists process of consumption involves looking at pictures and read about places that create an image of places that they have never been to. Websites are therefore important as a first impression and it is here that places are being represented. Places are created on the Internet and the Australian outback is an example of this. The study is interesting because it can be used to understand the relationship between people and places.

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Bakgrund: Att få en stomi är en stor kroppslig förändring som påverkar det dagliga livet. Detta kan göra de flesta patienter osäkra och påverka självbilden. Sjukdom som kan kräva en stomioperation är Kolorektalcancer, vilket är vanligt i västvärlden. I Sverige förekommer årligen ca 3000 nya fall av koloncancer och ca 1700 fall av rektalcancer. Det är sjuksköterskans ansvar att informera och undervisa patienter samt förvissa sig om att patienten förstår given information.

Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains?  Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.
