A midlatitude hail storm was simulated using a new version of the spectral bin microphysics Hebrew University Cloud Model (HUCM) with a detailed description of time-dependent melting and freezing. In addition to size distributions of drops, plate-, columnar-, and branch-type ice crystals, snow, graupel, and hail, new distributions for freezing drops as well as for liquid water mass within precipit
This paper presents a search for Higgs bosons decaying to four leptons, either electrons or muons, via one or two light exotic gauge bosons Z(d), H -> ZZ(d) -> 4l or H -> Z(d)Z(d) -> 4l. The search was performed using pp collision data corresponding to an integrated luminosity of about 20 fb(-1) at the center-of-mass energy of root s = 8 TeV recorded with the ATLAS detector at the Large Hadron Col
Substantial variation in milk coagulation properties has been observed among dairy cows. Consequently, raw milk from individual cows and breeds exhibits distinct coagulation capacities that potentially affect the technological properties and milk processing into cheese. This variation is largely influenced by protein composition, which is in turn affected by underlying genetic polymorphisms in the
Regional climate models are used by a large number of groups, for more or less all regions of the world. Regional climate models are complementary to global climate models. A typical use of regional climate models is to add further detail to global climate analyses or simulations, or to study climate processes in more detail than global models allow. The relationship between global and regional cl
Background: Accurate measurement of von Willebrand factor (VWF) is a critical requirement for the diagnosis of von Willebrand disease (VWD). Aim of the study: To evaluate the diagnostic efficiency of a rapid quantitative test for the measurement of VWF antigen (VWF:Ag) in type 1 VWD. Patients and methods: VWF: Ag was measured with an ELISA in a robotic instrument, as a reference method, and with a
Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45 degrees N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson B
Drought is a natural disaster that occurs globally and can damage the environment, disrupt agricultural production and cause large economic losses. The accurate prediction of drought can effectively reduce the impacts of droughts. Deep learning methods have shown promise in drought prediction, with convolutional neural networks (CNNs) being particularly effective in handling spatial information. I
Global warming has largely advanced spring vegetation phenology, which has subsequently affected terrestrial carbon and water cycles. However, further shifts in vegetation phenology under future climate change remain unclear. We estimated the start of the growing season (SOS) by applying multiple extraction methods based on the NDVI3g data set, and then parameterized and evaluated 11 spring vegeta
The past evolution of precipitation and atmospheric convection in the Western Pacific Warm Pool (WPWP) is critical for global climate changes but is under debate because of its forcing mechanisms. Here, we present a high temporal resolution (∼156 years) grain-size record of core MD01–2385 over the last 140 kyr, in offshore northern New Guinea to reveal sediment dynamics as a proxy for precipitatio
The present study highlights two important parameters of flute playing and musicalexpression: Sound and Articulation
The investigation of triggers causing the onset and intensification of Northern Hemisphere Glaciation (NHG) during the late Pliocene is essential for understanding the global climate system, with important implications for projecting future climate changes. Despite their critical roles in the global climate system, influences of land-ocean interactions on high-latitude ice sheets remain largely un
We investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L2(R; Rn), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. Our main result is that the se
Atmospheric trace gas measurements can be used to independently assess national greenhouse gas inventories through inverse modeling. Atmospheric nitrous oxide (N2O) measurements made in the United Kingdom (UK) and Republic of Ireland are used to derive monthly N2O emissions for 2013–2022 using two different inverse methods. We find mean UK emissions of 90.5 ± 23.0 (1σ) and 111.7 ± 32.1 (1σ) Gg N2O
This thesis analyses the compliance of the CCCTB directive proposals with certain aspects of Protocol (No 2) on the Application of the Principles of Subsidiarity and Proportionality. The thesis presents the various CCCTB proposals issued by the European Commission in 2011 and 2016. The analysis focuses on the CCCTB proposals’ compliance with the principles of subsidiarity and proportionality and h
Förenta nationernas klimatpanel (IPCC) uppmuntrar till djup och snabb omvandling inom varje ekonomisk sektor för att förebygga eskalerande klimatförändringar. I detta sammanhang har en offentlig och politisk debatt om luftfart som en stor källa till koldioxidutsläpp uppstått i Sverige med ökande antal människor som förklarar att de ”håller sig på jorden”. Trots att forskning har undersökt motivatiThe Intergovernmental Panel on Climate Change is encouraging profound and rapid transformation in every economic sector to mitigate escalating climate change. In this context, a public and political debate about aviation as a high-carbon source has emerged in Sweden with growing numbers of people declaring that they are “staying on the ground”. Despite increased research that explores the motivati
Despite the well-known threat that the use of fossil fuels poses to the climate many countries continue to provide large subsidies to the fossil fuel industry. The EU has declared that its member states should phase-out fossil fuel subsidies, but progress has been lacking and subsidies for fossil fuels in the EU remain large. This paper aims to understand which factors explain the persistence of s
Due to the climate crisis, more developing and emerging economies are considering to implement climate policies. However, since economic development remains high on their respective agendas, understanding economic consequences of such policies is crucial. The Porter hypothesis suggests in this respect that climate policy could benefit growth under certain circumstances by encouraging innovation, t
Okawangodeltat är södra Afrikas största våtmark och en av världens minst påverkade våtmarker. Kunskapen om hur våtmarkssystemet fungerar är begränsad, särskilt vad gäller halter av näringsämnen och omsättning av näringsämnen i de dominerande våtmarksväxterna. I den här studien presenteras analyser av kol- , kväve- och kiselhalter i Cyperus papyrus som är den dominerande akvatiska växten i stora deThe Okavango Delta is southern Africa’s greatest wetland and is among one of the most pristine wetlands in the world. There is moderate information about how this system functions, however, the research on nutrient concentrations and cycles is especially limited. This study provides new knowledge on the Okavango Delta by analysing samples of Cyperus papyrus, one of the main aquatic plants in the a
Scientific information is playing an important role in policymaking on climate adaptation by providing insight and guidance on efforts needed to reduce risks, respond to impacts, and build resilience. However, the extent to which science is influencing policy is questioned, as efforts being made are not reflecting efforts needed. Barriers in the interface between science and policy has found to be
This report investigates time optimization of a process where brazed heat exchangers are soldered in a vacuum furnace. This process consists of three phases, heating soldering and cooling. Physical models have been obtained by using stationary conditions. These are not sufficient to describe the actual very complex behavior. Instead, nonphysical models have been identified. Simulations of the heat
