Abstract:

The 1884 suggestion of Pierre Curie (1859–1906) that the type of dissymmetry shown by collinear electric and magnetic fields may induce an enantiomeric excess, in a chemical reaction that would otherwise produce a racemic mixture, is explored in the context of fundamental symmetry arguments. Curie’s arrangement exhibits false chirality (time-noninvariant enantiomorphism), and so it may not induce absolute enantioselection (ae) in a process that has reached thermodynamic equilibrium, since it does not lift the degeneracy of chiral enantiomers. However, it may do so in far-from-equilibrium proce

Abstract:

La escoria de alto horno es un subproducto de la producción de hierro y acero, cuyas características fisicoquímicas están influenciadas por el tipo de proceso de producción aplicado. Además, su composición química depende de las materias primas utilizadas, siendo las más comunes el mineral de hierro, el coque y la piedra caliza. La escoria puede solidificarse en cuatro formas diferentes: cristalizada, granulada, pelletized y expandida. La escoria cristalizada obtenida de la producción de altos hornos se estudió en este trabajo. Esta escoria tiene una alta porosidad y una resistencia mecánica r

Abstract:

By the time the first detailed reports on western Mexico's volcanic rocks had begun to appear in the 1970s, most of the earlier observations on these rocks and most knowledge of those who made these observations were all but forgotten. A review of previous field observations in this region shows, however, a long history of geologic discovery reflecting or even preceding developments elsewhere.Ethnological studies suggest that the Pre-Columbian inhabitants of the Sierra Madre Occidental (SMO) observed the characteristics of rock formations in their sierra homeland and understood something of th

Peripheral neural interfaces are used to connect the peripheral nervous system to high-tech robotic devices and computer interfaces. Soft materials are nowadays used to build the main structural part of these interfaces because they are able to mimic the mechanical properties of peripheral nerves. However, if on the one hand soft materials provide effective connections, reducing mechanical mismatch with nervous tissues and creating a close contact between active sites and neural fibers, on the other hand, most of them are not mechanically stable during implantation. As a consequence, tungsten

Abstract Extensive trials of PARP inhibitors (PARPi) have shown that they improve progression-free survival in patients with various cancers, including ovarian cancers.

To date, identifying patients eligible for PARPi has been a challenge for scientific and clinical teams using next-generation sequencing (NGS) analysis and the persistence of genomic scars in tumors after restoration of proficient HR or epigenetic changes is a limitation of NGS.

The cattle industry primarily employs embryo bisection in order to obtain genetic samples for pre-implantation screening and selection of embryos. Although practical and rapid, bisection is invasive and adversely affects embryo viability and cryopreservation. An alternative biopsy approach is to aspirate the blastocoele fluid (referred to as blastocentesis), which not only provides a genetic sample, but also has the potential to improve cryopreservation (Palini et al. 2013 Repro.

The disruption of Ca2+ homeostasis interferes with many Ca2+-mediated/dependent actions.

We used the CHK1 inhibitor, prexasertib, as a strategy to overcome platinum resistance by promoting cell cycle progression, limiting repair of platinum induced DNA damage. Sensitivit

Although CD30 expression is observed more frequently in MF with LCT vs without LCT, a wide range of CD30 expression levels is observed in LCT lesions and the level of expression lacks prognostic value for MF (Vergier et al.

The random first order transition theory (RFOT) describing the transition from a supercooled liquid to an ideal glass has been actively developed over the last twenty years. This theory is formulated in a way that allows a description of the transition from the initial equilibrium state to the final metastable state without considering any kinetic processes. The RFOT and its applications for real molecular systems (multicomponent liquids with various intermolecular potentials, gel systems, etc.) are widely represented in English-language sources.
