Emisión de gases de efecto invernadero en la economía mexicana y políticas de mitigación, 2020-2030
El Trimestre Económico, 2023 En este trabajo desarrollamos un modelo de insumo-producto medioambiental para la economía mexicana con el fin de explorar qué tanto es posible reducir la emisión de gases de efecto invernadero (GEI) en la economía para 2030.

Welding on C67 steel grade sheet: Influence of the parameters and post welding heat treatment
AIMS Materials Science, 2023 <abstract> <p>In batch operation, most industries require engineers to maintain low hardness on the welded parts, particularly for low carbon steel. This article focuses on tungsten inert gas (TIG) welding performed on 0.90 mm of a C67 grade sheet by varying different welding parameters such as current, velocity, and temperature.

Synthesis of a Truncated Analog of Amphidinol 3 Corresponding to the C21–C39/C52–C67 Section [PDF]
Chemistry Letters, 2017 As a part of structure–activity relationship studies to elucidate structure requirements for eliciting antifungal activity, an artificial analog of amphidinol 3 (AM3) was designed. A truncated analog corresponding to the C21–C39/C52–C67 section was synthesized by using Suzuki–Miyaura coupling and Julia–Kocienski olefination as key steps. An expeditious

General formulation for uniform and non‐uniform high‐strength steel slender I‐section beams
Steel Construction, EarlyView.Abstract The Ayrton–Perry approach is the basis of Eurocode 3 rules for buckling resistance, with distinct curves and imperfection factors depending on section type, steel grade, and other parameters. For generic members – built‐up or not, uniform or not, with complex supports or not – the code allows either the general method (clause 8.3.4 of Eurocode

Synthesis and Stereochemical Revision of the C31–C67 Fragment of Amphidinol 3
Angewandte Chemie, 2018 AbstractAmphidinol 3 (AM3) is a marine natural product produced by the dinoflagellate Amphidinium klebsii. Although the absolute configuration of AM3 was determined in 1999 by extensive NMR analysis and degradation of the natural product, it was a daunting task because of the presence of numerous stereogenic centers on the acyclic carbon chain and the ...

Demand Shocks, Export Diversification, and Firm Performance During the Great Trade Collapse
Journal of Economics &Management Strategy, EarlyView.ABSTRACT This paper analyzes the impact of external demand shocks from the 2008 to 2009 Great Trade Collapse on the performance of Chinese exporters and examines how export diversification mitigates these effects. Using Chinese Customs data merged with financial data from all listed Chinese firms, we construct firm‐specific demand shocks based on pre ...
