The double-network prepared with an in-situ monomer gel and a fast-crosslinked Cr(III) gel is introduced to develop a thixotropic and high-strength gel (THSG), which is found to have many advantages over the tradition...
The need for the analysis of modern businesses is rapidly increasing as the supporting enterprise systems generate more and more data.This data can be extremely valuable for executing organizations because the data al...
Transparency is vital to realizing the promise of evidenced-based policymaking,where"evidence-based"means including information as to what data mean and why they should be trusted.Transparency,in turn,requires that en...
