Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
As one of the primary countries of destination for migrant domestic workers in Asia, Singapore is a developed country with one of the highest standards of living in the region. Yet, the city-state has been on the receiving end of extensive criticism concerning the rights and protections of migrant domestic workers. Civil society organizations have been one of the loudest critics, and in recent pub
Following the structural transformation process in the 1990s, the government of Saxony set its hopes on the microelectronic cluster in its region to foster regional development and international competition. It is uncertain whether the cluster of Silicon Saxony has managed to meet these expectations. By comparing the cluster to four other major microelectronic clusters in Europe, the study assesse
Many biological wastewater treatment processes are based on bacterial biofilms, i.e. layered aggregates of microbial populations deposited on surfaces. Detachment and (re-)attachment leads to an exchange of biomass between the biofilm and the surrounding aqueous phase. Traditionally, mathematical models of biofilm processes do not take the contribution of the suspended, non-attached bacteria into
Pollination improves the yield of most crop species and contributes to one-third of global crop production, but comprehensive benefits including crop quality are still unknown. Hence, pollination is underestimated by international policies, which is particularly alarming in times of agricultural intensification and diminishing pollination services. In this study, exclusion experiments with strawbe
Climate change is increasingly recognized as a major security concern, with drought–migration–conflict linkages attracting significant attention in both policy and research. While some narratives portray drought as a direct driver of migration and conflict, evidence shows a far more complex relationship: climate stress can lead to more migration in some contexts and less in others, with internal m
10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state-of-the-art aerosol-climate model ECHAM6.3-HAM2.3-SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance stratospheric 10Be sedimentation, increasing atmospher
3I/ATLAS is the third interstellar object discovered to date, following 1I/‘Oumuamua and 2I/Borisov. Its unusually high excess velocity and active cometary nature make it a key probe of the Galactic population of icy planetesimals. Understanding its origin requires its past trajectory through the Galaxy to be traced and the possible role of stellar encounters to be assessed, both as a potential or
Reconstructions and simulations disagree on whether the Holocene exhibited a long-term cooling or warming signal. Anthropogenic land-use could be an important forcing regionally, but available population-based estimates differ widely. We examine transient Holocene climate model simulations forced with three population-based disturbed-land reconstructions and compare this with a fourth scenario der
Incorporating time as a unit of analysis can enrich the study of agency by showing the specific ways in which actors are temporally constrained when responding to economic disturbances. In this paper, this is done by examining how the behavior of actors is affected by timing norms such as term limits that may be associated with an actor's position, as for example, an elected mayor or university vi
Vad hände med innebörden av ordet "otrygghet", ett ord med gamla svenska rötter och en tidigare etablerad innebörd, när det amerikanska forskningsfältet "Fear of Crime" introducerade i Sverige och översattes till "Otrygghet"? Syftet med denna avhandling är att beskriva trygghetsforskningens uppkomst, etablering och expansion i Sverige, i syfte att besvara frågor om forskningsdiskursens funktion, sThe purpose of this dissertation is to construct an historical account of the emergence, establishment, and expansion of fear of crime research in Sweden. This dissertation aims to answer questions about the function, spread, and high level of institutional engagement of fear of crime research by analyzing the literature and examining the methodological, theoretical, and epistemological origins of
Sweden has the largest forest cover in the European Union, and for decades, Sweden's forest industry has pursued intensive forest management through tree plantations and clear-cutting in order to maximize wood production. The Swedish forestry sector is increasingly under pressure to transition away from intensive clear-cut forest management, but other forest management models are still a niche in
Parser generators are an indispensable tool for rapid language devel- opment. However, they often fall short of the finesse of a hand-crafted parser, built with the language semantics in mind. One area where generated parsers have pro- vided unsatisfactory results is that of error recovery. Good error recovery is both natural, giving recovery suggestions in line with the intention of the programme
In cold region, conceptual models assigned precipitation phase, liquid (rain) or solid (snow), cause vastly different atmospheric, hydrological, and ecological responses, along with significant differences in evaporation, runoff, and infiltration fates for measured precipitation mass. A set air temperature threshold (ATT) applied to the over 30% annual precipitation events occurring with surface a
Proteins evolve under a myriad of biophysical selection pressures that collectively control the patterns of amino acid substitutions. These evolutionary pressures are sufficiently consistent over time and across protein families to produce substitution patterns, summarized in global amino acid substitution matrices such as BLOSUM, JTT, WAG, and LG, which can be used to successfully detect homologs
I takt med digitaliseringen har det skett ett kommunikativt skifte som kräver de auktoritära myndigheterna att tänka om kring deras kommunikation. Idag har sociala medier öppnat upp möjligheten för myndigheter att skapa en lekfull och kreativ dialog med sina medborgare. Denna kvalitativa studie syftar till att öka förståelsen för myndigheters kommunikation på sociala medier i relation till värdeskAs a result of the digitalization, there has been a communicative change that requires authorities to rethink their communication. Today, social media has allowed authorities the opportunity to converse in creative and playful dialogues with their citizens. This qualitative study aims to increase the understanding of government communication on social media in relation to value creation. A semioti
Examensarbetet jämför tre olika metoder för dimensionering av en spont. Syftet med arbetet är att utreda hur de valda beräkningsmetoderna inverkar på dimensionerande snittmoment och dimensionerande förankringskrafter samt att undersöka hur resultaten från de olika beräkningsmetoderna varierar vid ändring av ingående parametrar. De tre beräkningsmetoder som jämförs är den analytiska metoden från SThis master thesis compares three different methods for dimensioning a sheet pile wall. The purpose is to investigate how the chosen calculation methods affect dimensioning moments and anchoring forces in a sheet pile wall and to investigate how the results from the different calculation methods vary when changing the input parameters. The three calculation methods that are compared are the analy
The Mesopotamian Marshlands form one of the first landscapes where people started to transform and manipulate the natural environment in order to sustain human habitation. For thousands of years people transformed natural ecosystems into agricultural fields, residential clusters and other agglomerated environments to sustain long term settlement. Moreover, the Mesopotamian Marshlands, located in o
