On April 12, guest researcher at STK Kaja Jenssen Rathe will give a presentation titled "Between Erotic Perception and Lived Openness: Merleau-Ponty’s Perspective". This is the third event in our digital lecture series Perspectives on Love, in which we explore different understandings of the concept of love.
Abstract:Due to their large mass and small aspect ratio, icebergs pose a threat to boats and offshore structures. Small icebergs and bergy bits can cause harm to platform hulls and are more difficult to discover remotely. When there is a risk of collision between icebergs and platforms, it is necessary to deflect its drifting course to ensure safe human operations in polar offshore regions. In this talk, I will present iceberg towing experiments carried out on Svalbard in September 2020...

The growth of the Greater Bay Area in South China is still heavily reliant on the access to cheap labor. This seminar examines the role of labor brokers in shaping rural-urban labor migration in China.
Abstract: We report on the observation of gravity-capillary wave turbulence on the surface of a fluid in a high-gravity environment. By using a large-diameter centrifuge, the effective gravity acceleration is tuned up to 20 times Earth’s gravity. The transition frequency between the gravity and capillary regimes is thus increased up to one decade as predicted theoretically. A frequency power-law wave spectrum is observed in each regime and is found to be independent of the gravity level and of the wave steepness. While the timescale separation required by weak turbulence is well verified experimentally regardless of the gravity level, the nonlinear and dissipation timescales are found to be independent of the scale, as a result of the finite size effects of the system (large-scale container modes) that are not taken currently into account theoretically.

Welcome to this seminar with guest speaker Stephan Kloos, Acting Director, Institute for Social Anthropology Austrian Academy of Sciences. The seminar is hosted by the research group Medical Anthropology and Medical History.
Abstract: I will present a Biot-Stokes formulation created by Ricardo Ruiz-Baier. The formulations consists of a fluid-structure interaction model for flow of a Newtonian fluid, coupled with Biot consolidation equations through an interface, and incorporates total pressure as an unknown in the poroelastic region. I will also present a preconditioner for this system which is robust in all parameters and apply the model to a third circulation process to show the velocity fields in the brains subarachnoid space.

This year's International Women's Day seminar at the University of Oslo will explore gendered and intersecting consequences of COVID-19, with particular emphasis on work and migration. Invited speakers, including Professor Beverley Skeggs, will consider the ways in which the pandemic has revealed and reinforced existing inequalities, both in Norway and globally.

China’s global economic and political power has expanded. How will China use its new position to change the world? How does the country’s rise change its self-perception?

In the first lecture of STK's new event series Perspectives on Love, Professor Tove Pettersen will consider Simone de Beauvoir’s philosophy of love.
Abstract: If a droplet smaller than the capillary length is placed on a substrate with a conical shape, it spreads by itself in the direction of growing fibre radius. We describe this capillary spreading dynamics by developing a lubrication flow approximation on a cone and by using the perturbation method of matched asymptotic expansions. The droplet velocity is found to increase with the cone angle but decrease with the cone radius. We show that a film is formed at the receding part of the droplet, much like the classical Landau–Levich–Derjaguin film. By using the approach of matching asymptotic profiles in the film region and the quasi-static droplet, we obtain the same film thickness as the results from the lubrication approach. Our results show that manipulating the droplet size, the cone angle and the slip length provides different schemes for guiding droplet motion and coating the substrate with a film.?

Organelle DNA is less protected than nuclear DNA and the risk of mutations could be high. How do eukaryotic organelles avoid the gradual buildup of deleterious mutations in the organelle DNA until function is lost?
