The aim of this Master’s thesis is to analyse the discourse of accessibility at the Regional Archives in Lund. The focal point of the study is the interaction between the archivist and the user of the archival records, which stems from questions regarding how archival records are mediated in the dialogue between the archivist and the user, and if the archive’s construct of access is perceived as a

Av miljö- och hållbarhetsmässiga skäl finns idag ett ökat intresse att använda trä som byggnadsmaterial. Björk har historiskt sett inte används i lastbärande strukturer på grund av dålig beständighet och låg formstabilitet. Genom den kemiska modifieringsprocessen acetylering, kan båda dessa egenskaperna förbättras. För att kunna använda det modifierade träet i lastbärande strukturer måste man dockModication of wood is carried out to increase the durability and dimensional stability of wood, and one of the modication methods is acetylation. Acetylation of wood means that polymers in the cell wall react with acetic anhydride. Today, acetylated wood is rarely used in load-bearing structures and there are only a few studies on how the fracture characteristics are affected by acetylation. A stu

The Geological Society of America has sponsored versions of the geologic time scale since 1983. Over the past 30 years, the Geological Society of America Geologic Time Scale has undergone substantial modifications, commensurate with major advances in our understanding of chronostratigraphy, geochronology, astrochronology, chemostratigraphy, and the geomagnetic polarity time scale. Today, many part

Abstract in UndeterminedUzbekistan, after gaining independence from the Soviet Union in 1991, had publicly declared that it would adhere to democratic governance principles in designing and implementing its public administration policies. As a newly-independent state with democracy claims, Uzbekistan had tried to establish new democratic institutions with an effort to capture international communi

This study evaluated the sample sizes necessary to estimate several soil and vegetation characteristics within 10% confidence intervals with 95% probability in three terra firme tropical rainforest sites. Across all three plots, the most spatially heterogeneous variables were measurements of total standing crop root mass, ground surface litter mass, litter fall, root growth and soil respiration wh

In Sweden, municipalities organize a large share of public services but the conditions for providing these services differ considerably due to differences in size and wealth. In the wake of financial stress and New Public Management reforms the Swedish local governments seeks new ways to make both ends meet and still manage the services to be in line with the present (not the past) demands of the

The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. Both actin and tubulin were shown to copurify with PM vesicles and this copurificati

Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. The distribution of the molecules between these two sites

Lignocellulose is widely recognized as a Sustainable substrate for biofuels production, and the enzymatic hydrolysis is regarded as a critical step for the development of ail effective process for the conversion of cellulose into ethanol. One key factor affecting the overall conversion rate is the adsorption capacity of the cellulase enzymes to the surface of the insoluble substrate. Pretreatment

Weak alignment of requirements engineering (RE) with verification and validation (VV) may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in lack of verification of new requirements and incorrect verification of old invalid requirements, leading to software quality problems, wasted ef

Over the past few decades, numerous wide (> 103 au) binaries in the Galactic field and halo have been discovered. Their existence cannot be explained by the process of star formation or by dynamical interactions in the field, and their origin has long been a mystery. We explain the origin of these wide binaries by formation during the dissolution phase of young star clusters: an initially unbound

Airway epithelial repair, by cell migration over a denuded, intact basement membrane, occurs rapidly in vivo. The present study examines microcirculation-derived factors in the reepithelialization process in the guinea pig. A well-defined tracheal zone was gently deepithelialized; no bleeding occurred and the basement membrane was left intact. Plasma exudation was visualized by use of iv colloidal

The pathogenesis of pulmonary fibrosis is a complicated chain of interactions between cells and molecules. During recent years bronchoalveolar lavage (BAL) in patients with various interstitial lung disorders has increased our knowledge of the fibrosis process and focused on new interesting interactions. Here we present an animal model which makes it possible to apply both morphological and immuno

Archaeologists seek to analyze patterns of similarity and difference among diverse kinds of assemblages that (1) vary in the number of specimens and (2) have been characterized by standard multi-category frequency distributions. Recent developments in computer simulation methods offer marked improvements in our ability to test statistical hypotheses about variation in relative taxonomic or typolog

Energy balances are analysed from a life-cycle perspective for biogas systems based on 8 different raw materials. The analysis is based on published data and relates to Swedish conditions. The results show that the energy input into biogas systems (i.e. large-scale biogas plants) overall corresponds to 20-40% (on average approximately 30%) of the energy content in the biogas produced. The net ener

As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One's fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,

Shedding of epithelium, increased venular permeability, and traffic of activated eosinophils and neutrophils may characterize asthmatic airways. This in vivo study involving briefly anesthetized guinea pigs examines whether epithelial denudation itself affects airway venules and granulocytes. Using an oral probe, a de-epithelialized tracheal zone (0.8 x 30 mm) was produced without bleeding or dama

Today's handheld computing devices equipped with novel wireless network technologies can provide their users with features such as mobility, multimedia support and group communication. On the other hand, the administrative effort required to enable all these features increases beyond the level that an ordinary user can manage. Ad hoc networks, being able to quickly organise themselves without user

Wheat straw is an abundant agricultural residue which can be used as a raw material for bioethanol production. Due to the high xylan content in wheat straw, fermentation of both xylose and glucose is crucial to meet desired overall yields of ethanol. In the present work a recombinant xylose fermenting strain of Saccharomyces cerevisiae, TMB3400, cultivated aerobically on wheat straw hydrolysate, w

Landscape genetics offers a powerful approach to understanding species’ dispersal patterns. However, a central obstacle is to account for ecological processes operating at multiple spatial scales, while keeping research outcomes applicable to conservation management. We address this challenge by applying a novel multilevel regression approach to model landscape drivers of genetic structure at both
