This paper investigates the compressive strength loss of wollastonite modified magnesium ammonium phosphate cement (MAPC) and magnesium potassium phosphate cement (MKPC) paste after exposure to NaCl freeze-thaw cycles, alternation of dry-wet (water medium and 3 % NaCl medium), H2SO4 and NaOH Birthday Card corrosion.The compressive strength loss was
Over 80% of patients with pancreatic ductal adenocarcinoma (PDAC) are diagnosed at a late stage and are locally advanced or with concurrent metastases.The aggressive phenotype and relative chemo- and radiotherapeutic resistance of PDAC is thought to be mediated largely by its prominent stroma, which is supported by an Tapes extracellular matrix (EC
A new type of semi-submersible drilling platform is designed.The numerical simulation software is used to analyze the heave response of the new platform in the frequency domain and time domain, and the semi-submersible drilling platforms with double-floating four-column structure and heave plate structure are compared with the new platform.This pap
Within the social movements and protest initiatives of the 1970s especially the punk movement not only questioned and provoked aesthetic values, but also has a major influence to the multitude styles of street and urban art until the present.Since early punks gathered together in the streets, squares or parks of London, and other cities in Europe o
We compare spot patterns generated by Turing mechanisms with those generated by replication cascades, in a model one-dimensional reaction-diffusion Paddles system.We determine the stability region of spot solutions in parameter space as a function of a natural control parameter (feed-rate) where degenerate patterns with different numbers of spots c
