The self avoiding walk (SAW) model of the polymer has been extended to study the equilibrium properties of double stranded DNA (dsDNA) where two strands of the dsDNA are modeled by two mutually attracting self-avoiding walks (MASAWs) in the presence of an attractive surface. We study simultaneous adsorption and force induced melting transitions and explore different phases of DNA. It is observed t
Applying evidence builds on the conclusions of the assessment of the evidence. The aim of the chapter is to describe a range of ways of summarising and visualising different types of evidence so that it can be used in various decision-making processes. Evidence can also be presented as part of evidence capture sheets, argument maps, mind maps, theories of change, Bayesian networks or evidence rest
Arctic ecosystems are warming nearly 4 times faster than the global average, which is resulting in plant community shifts and subsequent changes in biogeochemical processes such as gaseous fluxes. Additionally, herbivores shape plant communities and thereby may alter the magnitude and composition of ecosystem respiration and biogenic volatile organic compound (BVOC) emissions. Here we determine th
Pollution by chemicals and waste impacts human and ecosystem health on regional, national, and global scales, resulting, together with climate change and biodiversity loss, in a triple planetary crisis. Consequently, in 2022, countries agreed to establish an intergovernmental science-policy panel (SPP) on chemicals, waste, and pollution prevention, complementary to the existing intergovernmental s
In this study we derive analytically the equilibrium melting probabilities for basepairs of a DNA molecule with a defect site. We assume that the defect is characterized by a change in the Watson-Crick basepair energy of the defect basepair, and in the associated two stacking energies for the defect, as compared to the remaining parts of the DNA. The defect site could, for instance, occur due to D
Degrowth seeks to achieve a sustainable society in the future. It implies overcoming capitalist norms and structures. Economic organizations have found little attention in degrowth scholarship. The existing literature focuses on degrowth compatibility without the wider structural and societal consideration that degrowth implies. Further, it is riddled with incoherences, such as a supposed compatib
Straw and nutrients retained in soil are crucial for priming effect (PE) and consequently for soil organic matter (SOM) turnover. However, the mechanisms by which carbon (C), nitrogen (N), and phosphorus (P) and their stoichiometric ratios impact microbial communities and regulate the PE intensity remain controversial, particularly in the flooded rice soils. In this work, the PE dynamics and micro
Deoxygenation, i.e. loss of oxygen from the oceans, often considerably influences the aquatic organisms and the wholeecosystem and changes biogeochemical cycles. It results in increasing bottom areas of hypoxia (<2 mg/l dissolved oxygen),which has been primarily attributed to global warming and increased eutrophication. It is vital to study the present-dayanthropogenically-induced environmental ch
Background: Dental resin composites' performance is intricately linked to their polymerisation shrinkage characteristics. This study compares polymerisation shrinkage using advanced 3D micro-computed tomography (micro-CT) and traditional 2D linear assessments. It delves into the crucial role of filler content on shrinkage and the degree of conversion in dental resin composites, providing valuable
Differential growth is central to eukaryotic morphogenesis. We showed using cellular imaging, simulations, and perturbations that light-induced differential growth in a curved organ, the Arabidopsis thaliana apical hook, emerges from the longitudinal expansion of subepidermal cells, acting in parallel with a differential in the material properties of epidermal cell walls that resist expansion. The
With the amendment to the German Climate Change Act in 2021, the Federal Government of Germany has set the target to become greenhouse gas neutral by 2045. Reaching this ambitious target requires multisectoral efforts, which in turn calls for interdisciplinary collaboration: the Net-Zero-2050 project of the Helmholtz Climate Initiative serves as an example of successful, interdisciplinary collabor
The study analyzed the performance of Doho Rice Irrigation Scheme (DRIS), the largest public irrigation scheme in Uganda, using (1) water supply indicators comprising relative water supply (RWS), relative irrigation supply (RIS), and water delivery capacity (WDC) related to water supply from the system in relation to scheme crop water demand for the 2018–2019 growing season; and(2) water balance r
Feedback loops are among the core notions in systems thinking – and the various fields of theory and practice that draw on it, including systemic design. We use these notions to develop methodological approaches, conceptualise processes, assess the adequacy of solutions, and anticipate how the design object may interact with its immediate surroundings and beyond. In my presentation, I discuss the
At a geological time-scale, seas rise aloft and mountains crumble. We are currently in the middle of a debate on whether—in order to acknowledge the pervasive and geologically significant traces of human action on the planet—our present era should be labelled the “Anthropocene”, and if so, what would be the cut-off date for the commencement of that era. At the same moment, we are already contempla
Ecosystem functioning depends on biodiversity at multiple trophic levels, yet relationships between multitrophic diversity and ecosystem multifunctionality have been poorly explored, with studies often focusing on individual trophic levels and functions and on specific ecosystem types. Here, we show that plant diversity can affect ecosystem functioning both directly and by affecting other trophic
Bees are crucial for food security and biodiversity. However, managed bees are increasingly considered drivers of wild bee declines, leading to stakeholder conflicts and restrictive policies. We propose avenues to reconcile wild and managed bee proponents and point out knowledge gaps that hinder the development of evidence-based policies.
The vast potential of using sediment adsorbed DNA as a window to past and present biodiversity rely on the ability of solid surfaces to adsorb environmental DNA. However, a comprehensive insight into DNA adsorption at surfaces in general is lacking. Soot and charcoal are carbonaceous materials widespread in the environment where they read-ily can come in contact with extracellular DNA shed from or
The impact of climate change on surface ozone over Europe was studied using four offline regional chemistry transport models (CTMs) and one online regional integrated climate-chemistry model (CCM), driven by the same global projection of future climate under the SRES A1B scenario. Anthropogenic emissions of ozone precursors from RCP4.5 for year 2000 were used for simulations of both present and fu
