Grain Futures Market Response to the Black Sea Grain Initiative
German Journal of Agricultural EconomicsThis paper assesses the impact of the Black Sea Grain Initiative on the grain futures market. We rely on counterfactual evaluation techniques and detailed futures price series to estimate how corn and wheat futures prices and historical volatility responded to the Grain Deal enforcement, renewals, and termination.

Effect of Nucleant Particle Agglomeration on Grain Size
Metallurgical and Materials Transactions. A, 2022 Solute accumulation/depletion in the liquid around a growing solid particle during the solidification of metallic melts creates a constitutionally supercooled (CS) zone that has a significant effect on the final solidified grain structure. In this paper,

CORROSION OF GRAIN BOUNDARIES : INITIATION PROCESSES AND TESTING [PDF]
Le Journal de Physique Colloques, 1982 The aim of this paper is to discuss with numerous citations the processes which involve the initiation of the preferential dissolution at grain boundaries. Different parameters are considered : structural features, electrical properties, chemical properties, electrochemical and autocatalytic effects. Different tests are reviewed specialy with regard to

Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]
, 2013 The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at
