Shear and Tensile Strength Measurements of CaCO 3 Cemented Bonds between Glass Beads Treated by Microbially Induced Carbonate Precipitation
( American Society of Civil Engineers (ASCE) , 2023 , Article)The particle-scale shear and tensile strength measurements of microbial-induced calcite precipitation (MICP) treatment have been investigated in this paper. Glass beads were used to represent sand particles. Three ... -
Short-Term Effects of Experimental Warming and Precipitation Manipulation on Soil Microbial Biomass C and N, Community Substrate Utilization Patterns and Community Composition
( Soil Science Society of China , 2017 , Article)Soil microorganisms are major drivers of soil carbon (C) cycling; however, the response of these microorganisms to climate change remains unclear. In the present study, we investigated how 18 months of multifactor climate ... -
Short-term effects of warming treatment and precipitation manipulation on the ecophysiological responses of pinus densiflora seedlings
( Turkiye Klinikleri Journal of Medical Sciences , 2016 , Article)The aim of this study was to investigate the short-term effects of warming treatment and precipitation manipulation on the growth, photosynthetic rate, and chlorophyll content of Pinus densiflora seedlings based on a climate ... -
Short-term herbivory has long-term consequences in warmed and ambient high Arctic tundra
( Institute of Physics Publishing , 2017 , Article)Climate change is occurring across the world, with effects varying by ecosystem and region but already occurring quickly in high-latitude and high-altitude regions. Biotic interactions are important in determining ecosystem ... -
SIRT1, a novel transcriptional downstream target of CD44, linking its deacetylase activity to tumor cell invasion/metastasis
( Frontiers Media S.A. , 2022 , Short Survey)Our tetracycline-off-inducible CD44 expression system previously established in mouse model, revealed that activation of CD44 with its major ligand hyaluronan (HA) promoted breast cancer (BC) metastasis to the liver. To ... -
