Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

Deadwood in piles or distributed : does it make any difference to saproxylic beetles?

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.

Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

C?RONIS BIVAXFERNISSA En unders?kning av inneh?ll, l?slighet och ?ldringsegenskaper

The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc & Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis wax varnish. The study is based on contemporary conservation theory and interpretation-based decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has retained its solubility properties and transparency over time.

Tillämpning av naturvårdsavtal :

Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature. The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.

Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald

Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.

Nedfästning av oljemåleri på puts.En fallstudie från salongen på Mostorps slott i Halland

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

Arkeologi för alla : om anpassning av arkeologiska utställningar för funktionshindrade

Uppsatsen behandlar funktionshindrades tillgång till arkeologiska utställningar på museer. Syftet är att utreda hur man på bästa sätt kan anpassa arkeologiska utställningar för att fler besökare ska kunna tillgodogöra sig dem. Investeringar i form av nya kommunikationsstrategier och ett större samarbete museer emellan samt med handikapporganisationer krävs för att tillgängliggöra arkeologiska utställningar..

Mosslikens vara eller inte vara : Om mosslikens relevans som en egen fyndkategori och forskares sätt att skapa en sådan.

Is it relevant to treat bog bodies as its own category within the archaeological research? This paper examines how scholars and researchers, through their publications and depictions of the preserved prehistoric individuals, are helping to create such a category. What has changed in the way scholars look at and describe these astounding finds? Also examines the various theories researchers provide regarding bog bodies and how they are deposited..

Det sakrala landskapet i Olands härad

This paper analyses the existence and nature of the sacred landscape Olands härad during the Bronze Age and Iron Age. Olands härad is located in Northern Uppland, onthe way to Östhammar, about 30 km northeast of Uppsala. The interpretations are done with help of place names studies as well as archaeological finds. The results indicate that different types of cult locations can be found in the area..
