When an Extension of Nagata Rings Has Only Finitely Many Intermediate Rings, Each of Those Is a Nagata Ring

Let R⊂S be an extension of commutative rings, with X an indeterminate, such that the extension RX⊂SX of Nagata rings has FIP (i.e., SX has only finitely many RX-subalgebras). Then, the number of RX-subalgebras of SX equals the number of R-subalgebras of S. In fact, the function from the set of R-subalgebras of S to the set of RX-subalgebras of SX given by T ↦TX is an order-isomorphism

Entre rhétorique et ontologie : Le quotidien dans La Chute d’Albert Camus

Lorsque Camus publie La Chute (1956), ce monologue de Clamence commencé dans un bar poussiéreux d’Amsterdam, son intention est moins de nous faire, sous le mode de l’anecdote, le portrait d’un seul homme que d’en composer un qui soit « l’assemblage des défauts de notre génération dans toute la plénitude de leur développement ». Camus choisit cependant d’opacifier cet universalisme, en ne décrivant pas directement la génération lui correspondant, mais en le faisant entrer dans le particularism..

Sustainability in fashion industry : Solution statements for ecologically suitable management

Schon lange spielt Nachhaltigkeit in der Bekleidungsindustrie eine wichtige Rolle. Die Industrie wächst stetig, ohne jegliche Rücksicht auf die Umwelt zunehmen. Da dieses Thema sehr umfangreich ist, gibt die vorliegende Arbeit einen Überblick über die Auswirkungen des Baumwollanbaus in Entwicklungs- und Schwellenländern. Diese Arbeit hat sich das Ziel gesetzt, Lösungsansätze für ein ökologiegerechtes Management darzustelle

Oily formulations challenge: how to evaluate their beneficial effects in hydrophilic cell-based models?

In the European Union, Israel and India, testing cosmetic products or their ingredients on animals is prohibited. In this context, in vitro cell models play a pivotal role in the evaluation of both safety and beneficial effects of cosmetics. Oily formulations, widely used in cosmetics, are complex to study on cell models due to their lipophilic nature that doesn’t match with hydrophilic culture medium. Organic solvents are then required to solubilize oily formulations, but they can interfere with the cellular response. To avoid the use of organic solvents, we developed a method based on cells to evaluate potential beneficial effects of oily formulations. Our method, suitable for high throughput screening, consists in: (1) incubating cells with oily formulations for a short time followed by a recovery period in culture medium and (2) studying cell parameters using robust techniques such as cytofluorometry and fluorescence resonance energy transfer (FRET). Depending on the studied cell parameter, various beneficial effects can be revealed like antioxidant, anti-inflammatory and skin regeneration. The field of cell parameters is open and can be extended to new perspectives in the development of oily formulations
