Al‑Amiery 2,3*, Waleed Khalid Al‑Azzawi 4 & Wan Nor Roslam Wan Isahak 2 There is growing interest in using corrosion inhibitors and protective treatments to limit the degradation of mild steel, leading to the development of numerous Schiff bases as cutting-...
For various stories of mine, I've crawled into black-bear dens for Sports Illustrated, hitched up dogsled racing teams for Smithsonian magazine, checked out the Lake Champlain "monster" for Science Digest, and canoed through the Boundary Waters wilderness area of Minnesota for Destinations. 那以后...
A number of crystal structures1,2,3of antigen in the bound state have revealed an essential role of the solvent molecules in the hydration shell in stabilizing the complexes and have provided a detailed molecular basis for understanding the thermodynamics forces that drive the association between the...

(4) Damage destruction phase Ⅳ: The rock enters the residual deformation stage after macrocracks form, corresponding to the post-peak stress curve, and a small number of AE events still occur, showing that the damage variable gradually approaches a constant value with the increase in time. ...
All interval fractures were assigned a life equal to the greatest number of cycles for which the specimen was observed to be intact. Those specimens that survived to 400 × 106 cycles of straining were designated runouts. Several groups of test specimens that had all survived 400 × ...
where E represents evaporation, P is precipitation, and N is the total number of particles over the grid area. For this analysis, the particle trajectories were followed for 10 days, the considered average residence time of water vapour particles in the atmosphere72,73,74, and the final comput...
The protein and RNA composition of supermeres differs from small extracellular vesicles and exomeres. Supermeres are highly enriched with cargo involved in multiple cancers (glycolytic enzymes, TGFBI, miR-1246, MET, GPC1 and AGO2), Alzheimer’s disease (APP) and cardiovascular disease (ACE2, ...
Vegetation spectral reflectance obtained with hyperspectral imaging (HSI) offer non-invasive means for the non-destructive study of their physiological status. The light intensity at visible and near-infrared wavelengths (VNIR, 0.4–1.0µm) captured by
