Cet ouvrage s’attache à comprendre les modalités et les processus en jeu dans la construction des inégalités d’accès aux savoirs en EPS en croisant les regards sociologiques et didactiques. Selon les articles, la focale est mise sur les effets différentiels voire différenciateurs de la diffusion/appropriation des savoirs en fonction du type d’établissement, de la position scolaire des élèves, du genre ou du positionnement de genre et des profils des élèves, notamment ceux à besoins particuliers. Au-delà de leur spécificité, liée à l’ancrage disciplinaire et au contexte d’étude, les résultats exposés contribuent à éclairer les modalités de dépassement des inégalités d’accès aux savoirs. Ce livre s’adresse aux formateurs intervenant en formation initiale ou continue en EPS, aux chercheurs et doctorants en didactique(s) ou en sociodidactique ainsi qu’aux enseignants d’EPS ou aux étudiants se destinant au métier d’enseignant du premier ou du second degré.

Microorganisms (bacteria, archaea, microeukaryotes) in marine environments secrete a diverse array of exopolymeric substances that facilitate attachment to surfaces, the formation of organic colloids and larger aggregations of cells (marine snow), and that can influence many ocean, as well as global, processes. The aim of this Research Topic is to highlight recent advances in the sources, chemistry and function of these microbial-produced macromolecules. We encouraged original research and reviews on exopolymeric substances, from their sources, chemico-physiological properties, functions and ecosystem effects, and including their role in the Gulf of Mexico following the Deepwater Horizon oil spill disaster.

This book collects contributions to the Special Issue entitled "Symmetries in Quantum Mechanics and Statistical Physics" of the journal Symmetry. These contributions focus on recent advancements in the study of PT–invariance of non-Hermitian Hamiltonians, the supersymmetric quantum mechanics of relativistic and non-relativisitc systems, duality transformations for power–law potentials and conformal transformations. New aspects on the spreading of wave packets are also discussed.

Over the last few decades, the study of microbial biofilms has been gaining interest among the scientific community. These microbial communities comprise cells adhered to surfaces that are surrounded by a self-produced exopolymeric matrix that protects biofilm cells against different external stresses. Biofilms can have a negative impact on different sectors within society, namely in agriculture, food industries, and veterinary and human health. As a consequence of their metabolic state and matrix protection, biofilm cells are very difficult to tackle with antibiotics or chemical disinfectants. Due to this problem, recent advances in the development of antibiotic alternatives or complementary strategies to prevent or control biofilms have been reported. This book includes different strategies to prevent biofilm formation or to control biofilm development and includes full research articles, reviews, a communication, and a perspective.
