Kraft lignin and polyethylene terephthalate blends: effect on thermal and mechanical properties [PDF]

Polímeros, 2020
In this work, bottle-grade poly(ethylene terephthalate) (PETR), kraft lignin (KL), and chemically modified lignin (ML) were used to form blends to improve the mechanical and thermal properties of pure PET. The PET/KL and PETR/ML blends were produced with

Algorithmic Blending

Journal of Approximation Theory, 1993
An algorithm is given by wich one can obtain a 4-sided \(C^ 1\) surface patch. The algorithm can be used to interpolate 4 arbitrary polynomial boundary curves together with corresponding tangent planes. The method presented can be generalized to produce \(C^ K\) surfaces which are piecewise polynomial of degree \(2k+1\) or higher and which interpolate ...

Blended learning spaces: Synchronous blending

The JALT CALL Journal, 2011
Discussions of blended learning (BL) have generally failed to account for the synchronous combination of computer-mediated and face-to-face interactions that can occur within a blended learning space (BLS). is paper provides an overview of BLS use by a department of teachers at a Japanese university specializing in foreign language learning.
