Un nouveau paradigme architectural ?!

Nos modes de constructions actuels dits « fixes », devenus pour le moins obsolescents, cherchent des réponses émanant de l’économie circulaire. Cette myopie actuelle de la notion de déchet semble alors détrôner tout le principe de démontabilité. Durabilité, flexibilité, désassemblage, adaptabilité, déconstruction, réversibilité… sont tant de termes qui doivent s’imposer à notre nouvelle culture de la conception et construction dite « cradle to cradle ». Traversant les échelles, du plus fixe (structure, site) au plus flexible (spatialité, enveloppe), le bâtiment se résume alors par une superposition de strates indépendantes les unes des autres. En bout de chaîne, le cycle de vie du bâtiment se referme ; les matériaux devenus alors source directe de réemploi : ablation de la démolition en résulte.

L’objectif de ce travail est de sensibiliser et d’informer les architectes et autres acteurs de la construction des opportunités qu’offrent de telles pratiques. Une approche systémique qui semble soutenir de grands concepts architecturaux dépassant la théorie vers une pratique, encore qualifiée de science jeune mais illustrant pour autant des résultats prometteurs. Additionnels au cycle de vie fermé, comment quantifier cette approche circulaire, sur quels critères s’appuyer ? A new architectural paradigm ?!

Our current so-called "fixed" modes of construction, which have become obsolete to say the least, are looking for answers emanating from the circular economy. This current short-sightedness of the notion of waste seems to dethrone the whole principle of demountability. Durability, flexibility, disassembly, adaptability, deconstruction, reversibility... are so many terms that must be imposed on our new culture of design and construction known as "cradle to cradle". Crossing the scales, from the most fixed (structure, site) to the most flexible (spatiality, envelope), the building is then summed up by a superimposition of layers independent of each other. At the end of the chain, the life cycle of the building closes; the materials then become a direct source of reuse: resulting in the removal of the demolition. 

The aim of this work is to raise awareness and inform architects and other construction actors of the opportunities offered by such practices. A systemic approach that seems to support great architectural concepts that go beyond theory towards a practice, still qualified as a young science but nevertheless illustrating promising results. In addition to the closed life cycle, how can this circular approach be quantified, which criteria should be used ?

Sperm DNA damage is common and has been associated with reduced rates of conception, impaired embryonic development and increased risk of miscarriage. Although the exact causes of sperm DNA damage are unknown, it is clear that infertile men possess substantially higher levels of sperm DNA damage than do fertile men. Written by leading, internationally renowned clinicians and basic scientists with expertise in sperm DNA, Sperm Chromatin: Biological and Clinical Applications in Male Infertility and Assisted Reproduction provides readers with a thoughtful and comprehensive review of the biological and clinical significance of sperm DNA damage. The work covers the fundamental principles of sperm chromatin architecture and function, the proposed modes of DNA damage and repair, the tests of sperm DNA damage, the clinical aspects of DNA damage and the impact of DNA damage on reproductive outcome. Unlike any other title on the topic, Sperm Chromatin: Biological and Clinical Applications in Male Infertility and Assisted Reproduction is an invaluable addition to the literature and will serve as an indispensable resource for basic scientists with an interest in sperm biology and for urologists, gynecologists, reproductive endocrinologists, and embryologists working in the field of infertility.

This volume includes timely reviews of several aspects of chromatin biology written by scientists at the forefront of this rapidly moving field. Topics covered include the structure and function of protein modules within chromatin-remodeling proteins, newly characterized histone modifications (methylation, ubiquitylation) and their functional consequences, transcription and histone dynamics, roles of chromatin remodeling factors in DNA replication and repair, and current models of nucleosome-remodeling mechanisms.

Currently, the transition from using the combustion engine to electrified vehicles is a matter of time and drives the demand for compact, high-energy-density rechargeable lithium ion batteries as well as for large stationary batteries to buffer solar and wind energy. The future challenges, e.g., the decarbonization of the CO2-intensive transportation sector, will push the need for such batteries even more. The cost of lithium ion batteries has become competitive in the last few years, and lithium ion batteries are expected to dominate the battery market in the next decade. However, despite remarkable progress, there is still a strong need for improvements in the performance of lithium ion batteries. Further improvements are not only expected in the field of electrochemistry but can also be readily achieved by improved manufacturing methods, diagnostic algorithms, lifetime prediction methods, the implementation of artificial intelligence, and digital twins. Therefore, this Special Issue addresses the progress in battery and energy storage development by covering areas that have been less focused on, such as digitalization, advanced cell production, modeling, and prediction aspects in concordance with progress in new materials and pack design solutions.
