Roll-front uranium deposits are ore mineralizations that occur in sandstones or arkoses downstream from redox fronts or reduced/oxidized geochemical barriers. They are often bounded above and below by impermeable shaly/muddy layers making them ideal for in-situ leaching exploitation. Several stochastic simulations were previously investigated either to characterize the ore grade distribution within roll-front type deposits, or for describing geological processes involved in their formation. This work suggests some modifications/improvements of conventional geostatistical algorithms for honorin

Accurate debris-flow modelling depends on the ability to simulate surging and pulsing behaviour. However, our understanding of these phenomena is starved of observational constraints. Here we propose the use of seismic measurements, which resolve the arrival of coarse-grained roll wave fronts in debris flows at Illgraben, Switzerland. Roll waves likely play a key role in flow pulses but are typically only observed with point measurements like depth gauges. We compare in-torrent force plate measurements with near-torrent seismic records and discuss how these data can test existing roll wave the

We give a theory of permanent roll waves on a shallow layer of fluid mud which is modelled as a power-law fluid. Based on the long-wave approximation, Kármán's momentum integral method is applied to derive the averaged continuity and the momentum equations. Linearized instability analysis of a uniform flow shows that the growth rate of unstable disturbances increases monotonically with the wavenumber, and therefore is insufficient to suggest a preferred wavelength for the roll wave. Nonlinear roll waves are obtained next as periodic shocks connected by smooth profiles with depth increasing mon

For a pattern-forming system with two unbounded spatial directions that is near the onset to instability, we prove the existence of modulated fronts that connect (i) stable hexagons with the unstable trivial pattern, (ii) stable hexagons with unstable roll solutions, (iii) stable hexagons with unstable hexagons, and (iv) stable roll solutions with unstable hexagons. Our approach is based on spatial dynamics, bifurcation theory, and geometric singular perturbation theory.

Abstract This study investigates nonlinear waves ahead of cold fronts in the Great Australian Bight, south of the Australian continent.

AbstractA simple, isolated front is modeled using a turbulence resolving, large-eddy simulation (LES) to examine the generation of instabilities and inertial oscillations by surface fluxes. Both surface cooling and surface wind stress are considered. Coherent roll instabilities with 200–300-m horizontal scale form rapidly within the front after the onset of surface forcing. With weak surface cooling and no wind, the roll axis aligns with the front, yielding results that are equivalent to previous constant gradient symmetric instability cases.

A method is derived whereby fronts are identified as local maxima in sea surface height gradients. In this way fronts are defined locally as jets, rather than continuous-circumpolar water mass boundaries. A new climatology of Southern Ocean f

In early 1915, the Frost family made a hurried departure from England as the war in Europe escalated. Although they successfully escaped the ravages of World War I, at the time the most mechanized conflict in history, the Frosts returned to a country undergoing its own rapid and irreversible changes at the hands of technology. In the collection Mountain Interval, published in 1916, Frost depicts the violence of technology toward humans in poems such as “Out, Out –“ and “The Vanishing Red,” but most of the violence is reserved for plants and animals, both domestic and wild. He also addresses the role of technology in society, especially the telephone, and starts to move from observational to theoretical descriptions of astronomical objects. This chapter begins with an alternative interpretation of the natural setting in one of Frost’s most popular poems, “The Road Not Taken.”

Simulations are performed to study (i) the temporal growth of periodic disturbances of different wavelengths and Froude numbers and (ii) the spatial development of the wave packet produced by a local disturbance.

For vehicle frontal crash, the front wheels may affect impact load transfer and load path, and to some extent, the tire deformation may contribute to crash energy absorption. The effects would be especially prominent when it comes to the cases of micro car, offset crash and electric car. For a micro or small car, the front compartment space is small and the wheels are relatively large, and so the wheel’s role on transferring impact load to the A-pillar and the rocker is more significant and the energy absorbed by the tire deformation contributes to a relatively large portion.

The role of multilateral lenders in sovereign default has been traditionally overlooked by the literature. However, these creditors represent a significant share of lending to emerging markets and feature very distinct characteristics, such as lower interest rates and seniority. By including these creditors in a traditional DSGE model of sovereign default, I reproduce the high debt levels found in the data while maintaining default probabilities within realistic values. Additionally, I am able to analyze the role of multilateral debt in emerging economies. Multilateral loans complement private

Executive functions are high-level cognitive processes that enable individuals to plan, initiate, monitor, and adapt their behavior to achieve goals. This lecture-based paper explores the fundamental concepts of executive function and executive dysfunction, using clinical examples and neuropsychological theory. Drawing on recent case discussions and student engagement in a PS306 undergraduate neuropsychology course, this paper also examines methods of assessment, the role of the frontal lobes, and implications for clinical and educational contexts.

Learning to cope with disappointments and overcoming obstacles is part of growing up. By conquering some challenges, children develop resilience. Such normal stressors may include initiating a new activity or separation from parents during preschool hours. However, when the challenges in early childhood are intensified by important stressors happening outside their own lives, they may start to worry about the safety of themselves and their families. This may cause chronic stress, which interferes with their emotional, cognitive, and social development. In developing country contexts, it is esp

In policy circles and intellectual centers throughout the world, there is considerable debate on how to make globalization "work" for smaller, poorer, and otherwise disadvantaged countries. The challenges and potential solutions have manifested themselves in a myriad of ways, from the declarations of the Monterrey Summit on Trade and Development to policy papers on reform of the "global financial architecture". On the trade front, the World Trade Organization (WTO) launched the Doha Development Agenda in Qatar in November 2001, which sought, among other things, to give the challenges of capaci

Annotation:
Sliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to govern ice and snow friction, but directly validating the underlying mechanics has been difficult. This may be changing, as instruments capable of micro-scale measurements and imaging are now being brought to bear on friction studies. Nevertheless, gi

COVID-19 brought the public’s attention to the critical value of transportation and supply chain workers as lifelines to access food and other supplies. This report examines essential job skills required of the middle-skill workforce (workers with more than a high school degree, but less than a four-year college degree). Many of these middle-skill transportation and supply chain jobs are what the Federal Reserve Bank defines as “opportunity occupations” -- jobs that pay above median wages and can be accessible to those without a four-year college degree.

The EU must capitalise on its unique strengths in a highly competitive global arena. Its comparative advantages lie in areas where it has ample experience, know-how, legal competence, and institutional capacity. This policy brief offers recommendations to harness these strengths in conflict prevention, mediation and resolution. By doing so, the EU will be able to act more proactively, assertively and effectively on the international stage. 1.

After two relatively successful recent elections, the far-right Finns Party (FP) approached the early summer 2024 European Parliament elections amid a supranational atmosphere suggesting that these elections would mark a “turn for the far right” across both Europe and Finland. After successfully leading her party to a historic victory one year earlier in the national elections of Finland 2023, Riikka Purra was, according to polls and pundit opinions, heading toward a new election record—this time in the European Parliament.

En milstolpe skedde 2019 då vi fick ett brev från Israels ambassadör Ilan Ben-Dov, som resultat av en artikel vi hade skrivit på DN Debatt. Sedan dess har analyser och dialoger genomförts med tema Israel/Agtech. Syftet med resan som nu äntligen blev av var att ge ett keynoteföredrag, delta i diskussioner med svenska och israeliska företag samt göra studiebesök i innovationsmiljöer.
