Abstract CO 2 is a molecule that has already been used on a large scale for decades for a variety of applications: chemistry, agri-food, plant growth, extinguishing agent, water treatment... The geological storage of CO 2 has also been implemented for …

Abstract Achieving carbon neutrality (Net Zero) by 2050 requires, in addition to massive emissions reductions, the development of tools to actively remove CO 2 from the atmosphere. So-called "negative emissions" technologies have become an indispensable …

Abstract Most scenarios developed to limit global warming involve negative emissions, i.e. the sequestration of carbon dioxide from the atmosphere. In this context, ecosystems, which currently absorb almost a quarter of our emissions, represent one of the …

Abstract A commonly discussed form of geoengineering is the modification of solar radiation. A number of technologies could be used to reduce solar radiation incident on the Earth in order, in theory, to counteract global warming. In 2024, the European …

Abstract This presentation explores geoengineering – a set of ideas aimed at cooling the planet if cutting greenhouse gas emissions isn’t enough to stop climate change. It looks at two main strategies: Solar Radiation Management (SRM) and Carbon Dioxide …

Abstract François-Marie Bréon will introduce the conference by recalling the context of ongoing climate change and the need to limit warming to less than 2 degrees. He will describe the concept of geo-engineering, distinguishing between techniques aimed …

Abstract We discuss the role simplified controllable models may play in sharpening and solving questions in quantum cosmology. Some focus will be placed on lower dimensional models. Relevant literature includes 2406.15271, 2106.01665, …

Abstract Origin and evolution of the Osirian statue. Large groups of Osirid statues and pillars in temple lecture halls. Evolution of the mummiform type of accoutrement; transition from shroud to ceremonial costume. Representation of the god in royal …

Abstract Medical research has revealed an increase in pediatric cancers in many countries. While some suggest that this increase is linked to improved monitoring of children and diagnosis of their state of health, others point to major changes in the …

Documents and media Download support Abstract Work-related accidents are a major public health issue, affecting mainly low-skilled workers. Their scale remains underestimated, despite the fact that working conditions are becoming increasingly precarious. …

Abstract How does a biological system set up a body plan to produce a final organism with everything in the right place and orientation? I will discuss a developmental system (parhyale) that exploits activity and cell division to establish four-fold …
