The basic properties of the fly ash, recycled brick powder and recycled concrete powder, compared the recycled brick powder and recycled concrete powder instead of fly ash in concrete preparation, influence on the working performance and mechanical properties; ut solution gel for cats and through the modifier to improve the concrete slump loss is t
The pandemic crisis has forced the development of teaching and evaluation activities exclusively online.In this context, the emergency remote teaching (ERT) process, which raised a multitude of problems for institutions, teachers, and students, led the authors to consider it important to design a model for evaluating teaching and evaluation process
Ganoderma lucidum is a typical polypore fungus used for traditional Chinese medical purposes.The taxonomic delimitation of Ganoderma lucidum is still debated.In 15-eg1053cl this study, we sequenced seven internal transcribed spacer (ITS) sequences of Ganoderma lucidum strains and annotated the ITS1 and ITS2 regions.Phylogenetic analysis of ITS1 dif
Aiming at the problem of image tampering and forensic localization,a fragile watermarking algorithm based 15-eg1053cl on chaos sequence and image QR decomposition was proposed to determine the image tampering.The algorithm chooses QR decomposition to decompose the image,embeds the watermark after the image is decomposed,and encrypts the watermark b
