L’origine évolutive des dihydrofolate reductases de type B

Les enzymes dihydrofolate réductases de type B (DfrB), identifiées pour la première fois dans les années 1970, confèrent une forte résistance à l’antibiotique triméthoprime. Depuis, ces enzymes ont été étudiées en détail de manière enzymatique et biophysique. Alors que ces enzymes sont connues depuis cinquante ans, leur origine évolutive demeure un mystère. Ainsi, cette recherche […]

La dégradation des relations franco-britanniques

L’année 2021 est marquée par un accroissement significatif des tensions dans la relation entre la France et le Royaume-Uni. Les confrontations entre le président Macron et le premier ministre Johnson se sont accumulés, allant de mal en pis. Pourtant, la relation franco-britannique en matière de défense et de sécurité se porte particulièrement bien depuis les […]

Material Textualities: Literature between Collecting and Hoarding

In light of an urgent ecological demand for attentiveness to the non-human; outcomes. this proposal stresses the importance of the literary medium in addressing eco-critical questions. In essence, this project explores the interdependency of human and non-human entities through literary-material desires: collecting, hoarding, and discarding. My research thus asks how we can read literature under […]

Fate of the ash forming elements during combustion of biomass

In modern kraft pulp mills, the kraft recovery boiler can produce all the steam and electricity needed for the mill and even sell green electricity to the grid. However, most mills still have the fossil CO2 emissions from the combustion of fossil fuels in lime kilns. For mills to eliminate this source of fossil CO2, […]

The Molecular-Rich Outflow of Giant Stars

When stars like our Sun reach the end of their lives, they become giants and eject a lot of their initial mass through a slow, dense outflow. These winds are driven by microscopic solid particles (dust grains) that condense in the cool stellar atmospheres. The dust is the product of a large number of chemical […]

Predicting Reactions with Controlled Errors

Given a group of molecules and a specification of reaction conditions, do chemical reactions occur? If so, what products are produced, and what is their relative abundance? This problem pervades chemistry, with applications in environmental science (e.g., the degradation of pollutants), molecular sensing (e.g., interpreting the results of tandem mass spectrometry), chemical synthesis (e.g., finding […]

Particle identification using the in-flight fragment separator (FRS) at GSI

The GSI projectile fragment separator (FRS) is a versatile, high-resolution magnetic spectrometer designed to efficiently separate projectile fragments in their mass and nuclear charge. It has been efficiently used in the study of nuclear structure and reaction dynamics with relativistic radioactive heavy-ions over the last few decades. In the present project the intern will learn […]

Nuclear shell model calculations as input for astrophysical processes

The student will use the interacting shell model to study properties of ground and low-lying excited states as well as the corresponding electromagnetic and weak transitions for nuclei of importance for astrophysical scenarios like the nucleosynthesis in the r-process. For this the student has to learn about the shell model and how to perform and […]

TreeGraSP

Avec le développement en parallèle de technologies de traitement automatique des langues de plus en plus performantes, de théories linguistiques de plus en plus précises et de banque de données de plus en plus riches, il est maintenant plus facile de comparer les langues et d’identifier leurs points communs et leurs divergences. Un défi pour […]
