TL;DR: In this article , the impact of microwave heating on the air voids structures of steel slag asphalt mixture (SSAM) was analyzed by X-ray computed tomography (CT) and showed that microwave heating can reduce the micro voids in SSAM but increase the ratio of large voids and extra-large voids, which causes the decrease of durability.

TL;DR: In this paper , the stalagmite LS46 δ18O was collected from Luoshui Cave, Hubei Province, Central China, and was well-dated (a total of 24 230Th dates) and high-resolved sampled for oxygen and carbon stable isotopic measurements (2047 subsamples in total).

TL;DR: In this paper , a novel thermomechanical processing including solution treatment, first rolling with large deformation and overaging based on particle-stimulated nucleation of recrystallization (PSN) was proposed to obtain an Al-Mg-Si alloy sheet with fine grain structure, weak texture and high plastic strain ratio.

TL;DR: The impacts of anthropogenic forcing on Indian summer monsoon (ISM) rainfall are obscure, partly due to limited availability of highly resolved hydroclimate proxy records as well as the highly regionalized nature of precipitation as mentioned in this paper .
Abstract: The impacts of anthropogenic forcing on Indian summer monsoon (ISM) rainfall are obscure, partly due to limited availability of highly resolved hydroclimate proxy records as well as the highly regionalized nature of precipitation. Here, we report an annually‐resolved speleothem oxygen isotope record from Xianren Cave, southwestern China, which represents rainfall change over the broad ISM region. We find that the region has endured at least six decadal‐scale weak monsoon events in the past three hundred years. One of them, lasting from the early to mid 19th century, shares the similar gradual, persistent trend as the most recent decline in ISM rainfall and both have a magnitude substantially larger than the others dominated by natural variability. This early weak monsoon event occurred during a historical time of intensive deforestation in the region. We conclude that the ISM trend could have been altered by the changes in land‐use and land‐cover since the early 19th century.
