Besökarstudie i Kilsbergens rekreationsområden : en metod för att utveckla rekreationsmöjligheter på Sveaskogs marker
In this Master thesis an effective method is presented to find out what is requested in a forest or outdoor recreation. The aim with the study is to find out how Sveaskog can increase the general interest for experiences in nature and improve the access for recreation. Some questions that have been used to answer this purpose are: Who is visiting/not visiting the recreation area? How is it possible to increase the number of visits? The study is carried out in Kilsbergen and mainly centered around Ånnaboda, which is the natural place for people to meet at and undertake recreational activities.
The method that is used is a mail-survey that was sent to visitors and people living in Örebro. People living in Örebro represent potential visitors who live close to the recreation area.
Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.
Torvströ till svenska mjölkkor :
Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.
Trinitariskt språk hos Paulus Spänningsförhållanden i beskrivningen av Fader, Son och Ande
This essay is aiming to go through and study the most important and frequently mentioned terms and titles used in the letters of Paul to denote and describe God, the Father, the Son and the Spirit. These include ?Christ? and ?Lord? as well. The purpose has been two-fold: on the one hand I wished to study the background and meaning of the concepts in question, as used by Paul; on the other hand ? and this has been my main concern ? I specifically wanted to look at what kind of language Paul uses to denote Father, Son and Spirit in terms of their attributed characteristics, roles and theological functions.
The vertical farm : varför har idén uppkommit och hur är den tänkt att fungera?
By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.
Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel
Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management.
The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.
Den relativa viktens (kalv/ko) inflytande på kalvningsegenskaperna hos SRB och SLB :
Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not.
The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun
Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited.
The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.
Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn
Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.
Välkommen : vackrare infart till Vilhelmina
The purpose of this thesis is to show how a good approach can be designed, focusing on the southern approach to the Swedish town Vilhelmina. Prior to the car being part of everyday life, the approach was a road where the town showed itself from the very best side. When the amount of traffic increased, so did noise and other disturbances, and as a consequence industrial areas replaced the residential buildnings at the approaches. Today, the pendulum is turning back and in recent years the approach is regarded as a place to introduce the town. The approach is also the place where cars should slow down from the speed of the main road to the speed of the city.
Kalvutdragaren - en hjälpande hand? :
The calf extrator?s function has been studied, through measuring traction and how
this varies in different situations, in comparison with corresponding manual
traction situations. This was done against the background that excessive force at
assisted calvings at dystocia can mean life threatening damages on the calf such as
grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf
extractor has earlier been measured to pull with greater force than the established
maximum force of ?two strong men?.
För få kvinnliga toppchefer - hur förändrar vi den rådande situationen?
Bakgrund: Vi har idag en relativt jämn könsfördelning på den svenska arbetsmarknaden, men ju högre upp i företagens hierarkier vi klättar desto ojämnare blir fördelningen mellan kvinnor och män. År 2007 var 28 % av alla chefer i de svenska börsnoterade bolagen kvinnor och endast 2 % av VD:arna i dessa bolag var kvinnor. Varför situationen ser ut som den gör finns det inget givet svar på, men något som de allra flesta är överens om är att det behövs fler kvinnor på de höga chefsnivåerna. Det börjar bli allmänt känt att bristen på kvinnliga toppchefer är en riskfaktor för företagens kompetensutveckling, ledarskap och konkurrenskraft. Den senaste tidens intensiva debatt kring den låga andelen kvinnliga toppchefer har fått många ledare inom svenskt näringsliv att öppna ögonen och uttrycka en vilja till förändring.
Förutsättningar för återintroduktion av stora gräsätare i Sverige
Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.
Erfarenheter av utedrift med köttdjur i Sverige och Kanada :
Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.
