Synthesis and Structure Revision of the C43–C67 Part of Amphidinol 3
Stereoselective synthesis of the C43–C67 part of amphidinol 3 (AM3) and its C51-epimer was achieved starting from a common intermediate corresponding to the tetrahydropyran moiety of AM3, via asymmetric oxidations and Julia–Kocienski olefination.

Welding on C67 steel grade sheet: Influence of the parameters and post welding heat treatment
<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.

Demand Shocks, Export Diversification, and Firm Performance During the Great Trade Collapse
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 ...
