This essay concerns the site of Pompeii and its preservation. The aim is to investigate what causes the Decay of the ruins, how to prevent it and what consequences the tourism has on the site. The material consists of interviews with three Swedish scientists who are currently working with documenting a block in Pompeii. The result reveals a large number of threats against the city, such as climate, tourism and an inadequate economy situation. Examples of solutions are more investments which can be used for restorations and reconstructions, and guards to prevent vandalism.

The purpose of this study was to investigate parents' knowledge about diet and dental caries. The survey was conducted using a structured questionnaire consisting of 19 questions regarding knowledge of diet and caries, and preventive measures. The questionnaires were distributed to parents who were visiting a dental hygienist or prophylaxis nurse with their children aged 0-3 years. A total of 88 completed surveys were collected. The study showed that the majority of the parents had knowledge about diet and dental caries.

This essay deals with ruins from the perspective of their cultural values ??and the impact of add-ons, protective add-ons and caring actions affect these values. The issues in the essay are; What are the cultural values of a ruin?  How have ruins been used?  How are ruins treated today?Initially the definition of the concept ?ruin? is discussed, what is a ruin? A building has an architectural biography: the creation, destruction, change and the Decay. The concept of ruin is considered to be a state of this Decay, rather than a dead building.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and Decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and Decay stage were assessed to define any effect.

Studiens syfte är att undersöka arterna Buxbaumia viridis och Nowellia curvifolia för att kunna förutse var man hittar dessa signalarter. Detta gjordes genom att död liggande ved undersöktes i Ycke naturreservat samt en närliggande brukas skog, Östergötlands län.Resultaten visar att faktorerna som är avgörande för B. virids är markkontakt och nedbrytningsklass. B. viridis föredrar att växa på lågor i de högre nedbrytningsklasserna (4-7) och med stor andel markkontakt, över 80 %.

The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line. The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended. The users wished for an automated stamping tool.

Heartwood has always been a desirable part of the tree, due to it?s superior Decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.

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.

The following project has been made in collaboration with, Denator AB, a biotechnology enterprise. One-dimensional electrophoreses have been used to analyze protein contents of tissue samples. Tissue samples have been either treated according to the company´s newly developed tissue treatment technique or not treated at all and comparisons between these samples have been made. In order to see differences in protein patterns between samples more clearly, a conversion method has been developed where electrophoresis gel visual patterns are used to produce curves, similar to densitometer curves.Denator AB would like to know if the proteins in their treated samples will change visibly over 48 h when incubated at room temperature. This has been investigated using the above mentioned method.

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

The main purpose of this essay was to understand and discuss the problems the Swedishmunicipalities have when missing the profession in cultural preservation area. I have madetwo case studies where competence has been present in one and absent in the other. FurtherI intend to find out what material the Swedish municipalities needs in their work with theconservation of built environment.The first case describes Vallentunas main intersection and the adjustments needed toseparate it from the local rail road. It identifies what the municipality deems importantsuch as sight lines and access to the old church area. The ability to illuminate these itemshad not been possible without the knowledge and early participation of an expert in thefield of cultural resource management.The second case revolves around an old croft in Österåker that was subject for a plannedresidential area.

Denna uppsats undersöker dekadensens betydelse för Klas Östergrens generationsroman Gentlemen (1980). Syftet är dels att uppmärksamma ett hittills förbisett författarskap, dels att applicera en teori som kan belysa Gentlemen. Frågeställningen utgår därmed ifrån hur dekadensen återspeglas i romanens huvudkaraktärsskildringar, samhällsstämningar och form.Uppsatsens dekadensdefinition grundar sig i Paul Bourgets Théorie de la decadence (1883), där han skildrar samhällets, individens och språkets förfall. Utifrån dessa tankar antar jag en bred dekadensdefinition som fokuserar människans ambivalens inför att leva i en värdemässigt förfallen värld. Dekadensteorin är därmed utgångspunkten för analysen där jag genom närläsning urskiljer framträdande dekadenta drag.Framförallt betydande är den s.k.
