Water is a scarce commodity on Mars, yet large amounts of water are needed for crew life support, and in most human mission scenarios, even greater amounts of water are needed to produce propellants for departing Mars for the return trip to Earth. Evidence suggests that significant amounts of water occur as mineral hydration of magnesium or calcium sulfates in the accessible upper layer of Mars regolith at various scattered equatorial locations. Several sulfates occur on Mars with water content 20% to 50% of the sulfate mass. Several forms... of hydrated sulfates are known to provide a significant share of observed water-equivalent hydrogen in the upper meter of Mars regolith. These include “Gypsum” (CaSO₄⋅2H₂O) containing 20.9% H2O by weight, and “Epsomite” (MgSO4·7H2O) (commonly known as “epsom salts”) containing 51% H2O by weight, as well as hexahydrite (MgSO4·6H2O) and starkeyite (MgSO4·4H2O). Scans using the neutron spectrometer from orbit show a remarkable correlation between the occurrence of S and H in the equatorial region, indicating that hydrated sulfates are a primary source of H2O there. Recent higher-resolution scans using the collimated neutron spectrometer show significant pockets of higher H2O content. This implies that even higher local concentrations of H2O almost surely exist within those areas, most likely as hydrated sulfates.The power requirements to evolve H2O from a range of potential hydrated magnesium sulfates are moderate. We suggest that a human mission to Mars at equatorial latitudes based on hydrated sulfates as a source of water is a potential competitor to a mission at higher latitudes based on putative accessible ice. Read more

This study analyzes the evolution of chair design in the Argentine Republic as a sequence of paradigmatic transformations analogous to those described by Thomas S. Kuhn in The Structure of Scientific Revolutions. Through a qualitative hermeneutic approach, it examines three emblematic cases — the matera chair, the B.K.F. chair, and the Aro chair — all situated within the American Liberal Social Order, but corresponding to three successive aesthetics: non-modern (proto-rationalist), modern (neo-rationalist), and postmodern (eclectici...st).The analysis draws on the categories proposed by Jordi Llovet, who critically adapted Jean Baudrillard’s semiological concepts to the field of industrial design. Llovet’s four constitutive values of the designed object — functional, aesthetic, symbolic, and economic — are expanded here with a fifth, emergent value: socio-environmental use-value, integrating ecological sustainability, social justice, and the revaluation of local knowledge.The findings show that the matera chair exemplifies a phase of Kuhnian normal science (artisanal), in which the functional, aesthetic, and symbolic values appear unified. The B.K.F. chair, by contrast, embodies a Kuhnian paradigmatic revolution (industrial), characterized by the fragmentation of these values and the hegemony of exchange-value. Finally, the Aro chair illustrates a new crisis of the Kuhnian paradigm (industrial) and the gestation of a hybrid-sustainable paradigm (semi-industrial, semi-artisanal), in which the values are critically and ethically reintegrated.The study confirms that the everyday object — in this case, the chair — functions as a material document of historical revolutions, in which worldviews, modes of production, and social relations are contested.Read more

This article proposes the concept of a "quadimel," defined as a quantum-dimensional element, as a conceptual framework for describing quantum processes in both physical and biological systems. In the physical context, semiconductor quantum-dimensional nanocrystals are considered as candidate quadimels, with quantum electron transport examined using a one-dimensional Schrödinger-equation framework, transmission through a rectangular quantum well, and associated resonance and conductivity relationships. The concept is subsequently extended t...o biological systems, particularly DNA and RNA nucleotides, based on their molecular structure and proposed electronic properties. The manuscript further explores the possible relationship between the physical degrees of freedom of a proposed quadimel and quantum-information concepts such as qubits. The proposed biological interpretation is preliminary and speculative and should be distinguished from established research on quantum-mechanical electronic states in DNA and from established quantum-confinement physics. The article identifies potential applications in quantum information, nanoelectronics, communications, and biological research while emphasizing the need for theoretical and experimental validation of the proposed biological model.Read more
