The Chinese political system includes several million full-time professional staff often referred to as 'cadres'. Who are these local administrators, and how important are they for the Chinese Communist Party's developmental policies? How will it influence an individual to become a CCP cadre? In this seminar, we will examine cadres' roles from the perspective of two case studies, one focusing on environmental policies and the other with a focus on gender.

Abstract: T cell activation is initiated upon T cell receptor (TCR) binding to cognate peptide-MHC complexes on the surface of antigen presenting cells (APCs). This initiates the formation of the immunological synapse ¨C a specialized hub for bidirectional membrane transfer between T cells and APCs which is essential for processes such as downregulation of triggered TCR and T cell-mediated stimulation of B cells. Here, I will present some recent advancements in our understanding of how this is regulated.

Abstract: What links a baby¡¯s first breath to adhesive debonding, enhanced oil recovery, filtration or multiphase microfluidics? These processes all involve two-phase flows in rigid or elastic confined vessels and are often prone to interfacial instabilities. The canonical viscous fingering instability, which occurs when air displaces a viscous fluid in the narrow gap between two parallel plates, offers a versatile testbed for such phenomena. In this talk, I will use both experiments and numerical simulations of depth-averaged models to explore several aspects of bubble dynamics in Hele-Shaw cells. I will first show how the onset of fingering can be suppressed when replacing the upper plate of the vessel with an elastic sheet. Interfacial flows in narrow gaps can also exhibit considerable disorder, but they are rarely investigated from a dynamical systems¡¯ perspective. I will show how compliance can promote rich multiplicity of front propagation modes in a channel before turning to bubble propagation in a rigid channel with a depth perturbation. There I will explore how the bubble¡¯s organised transient dynamics is orchestrated by weakly-unstable steady propagation modes, and how its long-term behaviour may be practically unpredictable.

Gjesteforelesning med Hartmut Rosa om danningens (Bildung) rolle i det akselererende samfunnet.

Hvordan l?ser storsamfunnet dilemmaer knyttet til livssynsbaserte utdanningsinstitusjoner; dilemmaer som oppst?r i institusjonenes m?te med religi?se og seksuelle minoriteter, eller n?r institusjonene utfordrer samfunnets verdisyn slik dette er nedfelt i lov- og regelverk om h?yere utdanning? Dette fagseminaret etterf?lges av en panelsamtale om friskoler og skeive p? Litteraturhuset kl. 19.00. 

Abstract: A random, labyrinthine pattern emerges during slow drainage of a granular-fluid system in two- dimensional confinement. Compacted grains are pushed ahead of the fluid-air interface, which becomes unstable due to a competition between capillary forces and the frictional stress mobilized by grain-grain contact networks. We reproduce the pattern formation process in numerical simulations and present an analytical treatment that predicts the characteristic length scale of the labyrinth structure. The pattern length scale decreases with increasing volume fraction of grains in the system and increases with the system thickness. By tilting the model, aligned finger structures, with a characteristic width, emerge. A transition from vertical to horizontal alignment of the finger structures is observed as the tilting angle and the granular density are varied. The dynamics is reproduced in simulations. We also show how the system may explain patterns observed in nature, created during the early stages of a dike formation.

How important is gender for young people in contemporary China? What challenges and aspirations are central to young Chinese women? This seminar will focus on how young women from China negotiate different expectations and identities both inside and outside their homeland.

NCMM Associate Investigator, Professor Simona Chera, Group Leader of the Chera Lab at the University of Bergen will present her research as part of the NCMM Tuesday Seminar Series.

Over the last decade, the Kurdish areas in the Middle East have seen several violent conflicts. Hundreds of thousands of Kurds have been uprooted from their homes and areas of origin. This adds a new chapter to an already long history of displacement and migration. In this seminar, we will investigate some of the gendered aspects of these recent migration flows. The seminar will be held in English.
