“RAZA”: VARIABLES HISTÓRICAS [PDF]
Revista de Estudios Sociales, 2007 This article addresses "race" as a social practice, a construction, and as an idea that has been developed through the power of discourse. This category, rather than a biological reality, is an intellectual and social construction which has had a variety of meanings attributed to it through history.

Angewandte Chemie, EarlyView.Atmospheric water harvesting (AWH) under arid conditions requires desiccants that load water below 30% RH and regenerate below 60°C, a performance regime traditionally limited to physisorbents. Here, we show that the inherent hydrolytic instability of M′FSIX‐25‐M coordination networks enable regeneration‐optimized chemisorbents (ROCs) with projected ...

Twin‐Lever Multifunctional Meta‐Optics With High Longitudinal Tolerance
Advanced Science, EarlyView.We introduce a single‐layer, CMOS‐compatible metasurface that allows for polarization‐programmable, achromatic broadband dual‐mode imaging with high longitudinal tolerance. The twin‐lever design combines bright‐field focusing and vortex‐based edge‐enhanced imaging while managing axial intensity distribution from 488 to 633 nm.

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.
