This article provides a review of the application of stomatal frequency analysis to fossil leaves in the reconstruction of past atmospheric CO2 concentrations. It presents the physiological basis of the method, an overview of its application to leaves of Quaternary age, and an assessment of its potential and limitations. It also includes a description of the successive stages in a stomatal frequen

The 'street' and 'youth' have long been issues of social concern and the subject of research both in Brazil and elsewhere. The perception and experiences of youth in relation to the street, however, and the corresponding gender and class relations which permeate these, remain an under-researched topic. Drawing on fieldwork conducted in low- and middle-income neighbourhoods in Recife, this paper sh

Here, we present how small-angle scattering and neutron reflectometry can be combined with computer simulations to characterise the structure and response of soft, compressible microgels, both in dilute condition and in crowded environments. After introducing the concept of softness, we summarise the principles of these scattering methods and describe the numerical synthesis of microgels. Then, we

The History of Education as History of Knowledge brings together international scholars to explore how the emerging field of the history of knowledge can enrich the well-established history of education. While recent research in the history of knowledge has examined actors, practices, and institutions of knowledge, this volume is the first to focus systematically on sources and methodologies withi

During the 20th century, international law has developed towards individualization. Global human rights norms are paired with increased consideration for victims of violations. Simultaneously, trafficking in humans has become a major activity of organized crime, currently one of the most serious human rights issues in Europe. In the light of this, this thesis will examine how the right to be free

Apart from the substantive public procurement rules, harmonising national provisions for the award of public contracts, the Community also strives to ensure compliance with those rules. For that purposes the Remedies Directive 89/665/EEC has been adopted to ensure that effective and rapid remedies are available to aggrieved bidders. This directive has recently been amended by Directive 2007/66/EC

Compressed air systems account for roughly 10 % of industrial electricity use, suggesting that even marginal gains in compressor efficiency yield substantial cost and emission savings. Although screw compressors are valued for their compact and reliable design, the process of optimizing the performance of a machine for a specific application is typically time-consuming due to manual testing under

What makes a place meaningful to a community, and what happens to those meanings when the city changes? This thesis investigates architecture's role as both keeper and creator of collective memory in urban environments. Building on sociological theories, this research explores how memories are stored in the built environment, not as static entities but continuously formed, repeated, and trans

This study investigated the influence of various native and modified starches on the quality and staling behaviour of gluten-free bread. Four starch types: native wheat starch, cross-linked tapioca starch, fractionated native potato starch (FPS), and acetylated potato starch (Amylacetate) were evaluated by incorporating them into a standardized gluten-free bread formulation as the main starch sour

The development of plant-based foods has increased interest in sustainable and natural protein-based emulsifiers that may partially replace conventional/synthetic emulsifying ingredients. Rapeseed press cake is an underutilized protein rich side stream from oil production with potential for valorization as a functional food ingredient. This study evaluated the emulsifying properties of protein fra

Laccases are multicopper oxidases capable of oxidizing a broad range of phenolic and non-phenolic compounds, making them attractive biocatalysts for lignin valorization and environmental applications. In this work, two bacterial laccases, LacA from Bacillus amyloliquefaciens and MEK from Psychrobacter sp., were recombinantly produced in Escherichia coli BL21 (DE3), purified, and characterized to s

The study examines the role of sugar as embedded in society from the perspective of social constructionism. The health effects of sugar are an everyday phenomenon whose effects often remain invisible but have significant impact on societal structures and the individual level. The study is a case study analysing how Nestlé, and social movements, Action on Sugar and Foodrise construct meanings aroun

NrdR is a bacterial transcriptional repressor consisting of a zinc (Zn)-ribbon domain followed by an ATP-cone domain. Understanding its mechanism of action could aid the design of novel antibacterials. NrdR binds specifically to two “NrdR boxes” upstream of ribonucleotide reductase operons, of which Escherichia coli has three: nrdHIEF, nrdDG and nrdAB, in the last of which we identified a new

Artificial Intelligence (AI) technologies are increasingly researched and applied for medical knowledge discovery and to support or automate clinical decision-making. The aim of this thesis is to increase the knowledge on (1) how AI experts, radiologists, and standardizers make sense of AI, in the processes of medical AI development, clinical use and standardization, and (2) how this sensemaking c

Developing a reliable procedure for the growth of III-V nanowires (NW) on silicon (Si) substrates remains a significant challenge, as current methods rely on trial-and-error approaches with varying interpretations of critical process steps such as sample preparation, Au-Si alloy formation in the growth reactor, and NW alignment. Addressing these challenges is essential for enabling high-performanc

Disseminating research in wildlife management is challenging. This study explores how framing four information texts influenced Swedish crop farmers’ (n = 1,182) perceived ability to cope with wild geese, and their behavioral intentions to implement goose damage prevention strategies. A digital survey, based on a before–after randomized controlled trial, evaluated the impact of message framing wit
