American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Animal Models and Experimental Medicine, EarlyView.This study develops a reformulated tribromoethanol (TBE) anesthetic using 1,2‐propanediol as a solvent to overcome solvent‐related toxicity. The novel formulation demonstrates, cardiovascular stability, and survival in prolonged protocols. It provides potent, dose‐dependent anesthesia without strain or sex differences.

Boletín de la Sociedad Española de Cerámica y Vidrio, 2005 The low friction coefficient coatings are a new approach to substitution of oil lubricated systems. The introduction of a solid lubricant in a matrix with good mechanical properties gives to the system a low friction coefficient and improves the wear ...

Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis
Advanced NanoBiomed Research, EarlyView.Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...

Comportamiento viscoso de lubricantes e altas presiones
, 2012 Esta Tesis Doctoral se centra en el estudio del comportamiento viscoso a alta presión de diferentes lubricantes de tipo mineral, vegetal y sintético. Cinco líquidos analizados a lo largo de este trabajo pueden ser usados como materiales de referencia para la calibración de viscosímetros a presión: di (2-etilhexil) sebacato, di (2-etilhexil) ftalato ...
