Propiedades físicas y densitometría de rayos X en tableros de residuos de madera
Revista Ciência da Madeira - RCM, 2018 The objective was to evaluate the physical properties and densitometry of X-ray in particleboards produced from waste of sawmills eucalypt wood. In the production of panels was used commercial tannin extracted from the bark of Acacia mearnsii to 10% and ...

Why Are All the Sets All the Sets?
Noûs, EarlyView.ABSTRACT Necessitists about set theory think that the pure sets exists, and are the way they are, as a matter of necessity. They cannot explain why the sets (de rebus) are all the sets. This constitutes the Ur‐Objection against necessitism; it is the primary motivation cited by potentialists about set theory.

A Molecular Hybrid 2D/3D Carbon Allotrope: Synthesis of Adamanphene
ChemistryEurope, Volume 4, Issue 3, March 2026.Adamanphene fuses diamond and graphene at the molecular level. An adamantane core anchors four hexabenzocoronene nanographenes into a rigid tetrahedral architecture, giving rise to a porous π‐stacked solid with electronically isolated chromophores and aggregation‐induced emission.

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant
New Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

New Phytologist, Volume 249, Issue 6, Page 2974-2985, March 2026.Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown.
