​The Norwegian national commemoration of the twentieth anniversary of UN Security Council Resolution 1325 on Women, Peace and Security (UNSCR 1325) will consider both the major achievements of the past two decades, and the challenges that lie ahead. 

Welcome to our GEOHYD Lunch Seminar Friday 6th of November @ 12:15 via videolink using Zoom. The seminar is helt by Trine Jahr Hegdahl, Dept. of Geosciences.

Abstract: Upon burst, air bubbles release droplets that transfer biological and chemical materials from water bodies to the atmosphere. This mechanism is one of the main sources of cloud condensation nuclei and participates to airborne contamination when the bulk water contains pathogens. Predicting the size and composition of droplets emitted by bubbles requires a fundamental understanding of their dynamic at the surface, yet a consistent physical picture is lacking. Relying on experimental data from bubbles generated in various environments and using scaling analysis, I will show that surface tension gradients control the drainage of bubbles. I will also explain how local perturbations of surface tension can explain their seemingly stochastic burst mechanism. Consequences for application purposes will be mentioned throughout the presentation: I will notably take the examples of bubbles in saltwater and in water contaminated with bacteria.

This talk is part of the Mechanics Lunch Seminar series. That means 20min talks plus discussion in an informal setting.

Sorption of PFAS onto synthetic hydrous iron oxides

Tor Ole Odden:

"The field of educational research has a massive literature base, with many journals that have been publishing articles for almost a century (or longer). How do we sort through and make sense of literature at this scale? We have begun using an unsupervised machine learning technique from the field of natural language processing, known as latent Dirichlet allocation, to analyze articles from the fields of physics education research and science education research. This technique allows us to extract latent themes, or topics, from the literature and quantify the rise and fall of those topics over time.

In this talk, I will present the basics of the technique, describe some of its underlying theory and applications, and showcase some of the trends that it reveals in how science education theory and practice has evolved over the last 20-100 years."
