The aim of this bachelor thesis has been to investigate some of the materials present in and onprinted papers which might be suitable for analysis. A brief history of paper making and somepigments were studied after which the theory of some of the available methods for technicalanalysis were summarized. Two works of art on paper were chosen for a closer examination,both are woodblock prints but of different composition and origin. The investigation wasmade to exemplify some of the common techniques applied on works of art. There were twoaims in these examinations.

Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.

The activity of interest groups in the political process of the European Union has given rise to a broad debate concerning the effect on European democracy these groups have. As relatively powerful political actors, the question of these groups? views on the EU and how the union should be is an important one. The status of these groups owns democratic representation also affects the democratic status of the EU. Being based on a number of theories, this study adopts an ideology analysis for the purpose of testing these theories on two cases ? the Swedish environmental organizations World Wide Fund for Nature and The Swedish Society for Nature Conservation.

ABSTRACTThis thesis focuses on the OPEC oil crisis of 1973 and its impact on the Scandinavian countries of Sweden and Denmark. Starting from Walter Carlsnaes theory of energy vulnerability, the concepts of vulnerability and national security are tested on the selected cases and an array of policy alternatives are assessed. Posited available options like oil stockpiling, conservation, renewable energy and international coordination are evaluated as means for ameliorating the vulnerability of the nations. The theory chosen is further expounded with a consensus element to reinforce its explanatory power. The thesis utilizes a wide range of material from parliamentary records to daily newspapers in an attempt to shed some light on the interplay between economics and politics.Sweden and Denmark evince diverging developments despite their common starting point with exceptionally high oil dependencies and can be located on different ends of the energy policy gamut.

The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.

Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.

The purpose of this study was to understand how the concept of quality as an idea was spread to and translated in municipal elderly care. A central question was: How does literature, policy documents and key people describe the function and meaning of the concept of quality? The method of analysis was a qualitative case study with a critical discourse. The theoretical framework of the study is mainly what is known as institutional theory and a line of thought describing how ideas are transferred and spread. The theoretical focus is on how original ideas are interpreted and why they gain a foothold in new contexts.

This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.

One of the main reasons for the massive loss in plant species diversity is the fragmentation of habitats. In Europe, open pastures and meadows are the habitats going through the most changes during the 20th century, according to the agricultural changes. In this study vascular plants were invented at five different islands in the Lurö archipelago, Vänern, Sweden. The aim of the study was to sort out whether the diversity of plants has gone through any changes in abandoned managed grasslands compared to continuous managed grasslands. The aim was also to study if a change in the landscape has made any differences for the species development or decline.

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

This study is based on a case study of Pilotprojekt Drevfjällen, a project whose ambition is tofind ways to secure nature conservation in a local context. This is promoted at governmentlevel, which says that a local connection is needed to achieve sustainable regionaldevelopment. The study, based on a theoretical background of the concept of governance,intends to evaluate whether Pilotprojekt Drevfjällen can contribute to a sustainable regionaldevelopment.This study is based on meeting documentations, semi-structured interviews with variousstakeholders in the project, field studies and participant observation at an informativemeeting. The region of interest, north Dalarna, was visited twice to obtain the specificconditions that Pilotprojekt Drevfjällen have. The interviews revealed positive attitude to theincreased dialogue and cooperation that Pilotprojekt Drevfjällen has meant for theparticipants.

Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).
