Hassel (Corylus avellana) som indikator på markanvändningshistorik

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige

Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.

Lövsuccessioner i sluttningar längs nedre Umeälven :

Secondary deciduous forests, which have their origin in earlier pasture- and meadow-land in slopes along the lower reaches of the Ume river, are thought to contain high nature conservation values, in spite of a relatively low age. The aim of this study was to clarify how factors as historical use, exposition, disturbance dynamics and successional age influences the conservation values in these types of riparian forests and how this can be implicated in the practical work with conservation and management at Umeå municipality. Sample plots were placed in seven stands with a variation of their historical use, exposition, disturbance dynamics and age of succession. Conservation values as structure, tree-regeneration, abundance and composition of vascular plants, amount of dead wood and the abundance of signal-species were measured and registered. The species composition and especially the composition of tree species, differed between forests with different exposition and different historical use.

Jordbrukets påverkan på Östersjön : en jämförelse av indikatorer för att beskriva näringsbelastningen

The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms. One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

Didaktiska arter

The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.

Medeltid i samtid : Salvestaden en rekonstruktion i mellanlandet

The Middle Ages in contemporary time ? Salve City; a reconstruction in the Between Land is an essay dealing with the reconstruction of medieval Kalmar. The Salve City is a melting pot of such diverse fields as archaeology, pedagogies, reconstruction, historical tourism, regional development policy et cetera. Together, these parts form a space for research and mediation, business and pleasure, a place where commercialism and historical tourism can function alongside with history enthusiasts and entrepreneurs. Both pros and cons of the use of a reconstructed part of medieval Kalmar are debated..

Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden

Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.

Förmedling och framställning av historia i Tv-spel : En analys av den historiska miljön och atmosfären i Red Dead Redemption

This bachelor´s thesis analyzes the video game Red Dead Redemption and the historical use of the environment and atmosphere in the game. The theory and method used is media research and social memory studies. Two questions were asked: how does Red Dead Redemeption convey and produce the historical environment and the historical atmosphere. Furthermore subqueries/criterias were used to help answer the main questions.The analysis was divided into two parts, the first part we analyze and discuss the games historical environment and the second part analyzes and discusses the historical atmosphere of the game.The conclusion is that both the historical environment and the historical atmosphere is present in the game through picture and sound, the text only works as a guide. The picture and sound live in a symbiotic relationship and depend on each other to fully immerse the player to the game.

Land Art och dess förhållande till landskapsarkitektur idag

I den här uppsatsen undersöker jag vad Land Art är och hur den yttrar sig idag, samt vilket förhållande Land Art och landskapsarkitektur har. Vad skiljer och vad förenar? Jag intresserar mig ochså för om begreppen har närmat sig varandra sedan slutet på sextiotalet..

Lokalhistoria i undervisningen : En analys av 6 gymnasielärarnas historiebruk och 4 gymnasieelevers historiemedvetande på några svenska gymnasieskolor.

The purpose of this study is to examine if, how and why history teachers work with local history projects in education. The results will be analyzed based on a theory of the uses of history. I also investigate, through group interwiews with students, if and how students? historical consciousness may develop through teaching about local history. The result is a variation map of teachers? different uses of history and how students historical consciousness can manifest itself.The results of the study shows that all the teachers interviewed uses local history projects in education.

Kvinnors rätt till land : jämställdhet, formalisering och fördelning

The differences between the sexes when it comes to land and property ownership are enormous. This paper deals with issues concerning women's land and property rights. The aim of the study is to investigate what general factors are effecting women's access to and control of land. In addition, this paper aims to explore the effects of liberal formalism in relation to gender equality and the distribution of land. Formalism and formalization of women's land rights alone won't lead to equality in land distribution or women's emancipation.

Markanvisning och markanvisningsavtal : definitioner och innebörd i ett antal Stockholmskommuner

The purpose with this thesis is to investigate how a number of municipalities in Stockholm County proceed when they allocate land and establish land allocation agreements for exploitation, and to investigate how a number of municipalities define land allocations and land allocation agreements on the occasion of public land sales. The aim of this thesis is to describe the allocation methods a municipally uses when they offer land for sale and to give an insight regarding which correlation different land allocation agreements have in different municipalities.Methods used are: (1) a literature review where the underlying theory for land allocations and land allocation agreements have been studied; (2) a questionnaire have been done to complement the literature review and to provide a picture of how a number of different municipalities in Stockholm County use and apply land allocations; (3) an agreement audit have been done to see the extent to which different agreement terms exists.Responses from the questionnaire, together with the definitions form different municipality?s land allocation policies and the literature review, resulted in a definition of a land allocation and a land allocation agreement. The agreement audit shows that agreement terms regarding: price or price indication, location, cost-sharing and planning costs are the most common agreement terms within the municipalities we have investigated.The study suggests that there is some confusion regarding land allocation agreements and the meaning of these, that became apparent when agreements where gathered, despite a careful explanation that it was land allocation agreements we requested, we still got exploitation agreements and purchase agreements. Therefore, we consider it necessary with an official definition of a land allocation agreement well anchored in the Planning and Building Act together with the rules of development agreements or other legislation.That there is a lack of research within the subject becomes evident when reports, essays, and other literature generally refers so the same sources.Keywords: land allocation, land allocation agreement and public land sales.

Value-at-Risk : Historisk simulering som konkurrenskraftig beräkningsmodell

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

Elektriskt system för detektion vid ballistiskt prov

The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.
