Poly(ethylene glycol) (PEG)-glycosaminoglycan (GAG) hydrogel networks are established as very versatile biomaterials. Herein, the synthetic gel component of biohybrid materials is systematically varied by combining different poly(2-alkyl-2-oxazolines) (POx) with heparin applying a Michael-type addition crosslinking scheme: POx gradated hydrophilicity and temperature-responsiveness provides poly...

The paper introduces a straightforward procedure for estimating the electrical parameters of simple, but reasonably accurate, two-branches model supercapacitor (SC). equivalent circuit includes voltage and frequency dependence on SC’s capacitance, neglecting self-discharge phenomenon, so it is mainly devoted to short mid-term simulations suitable most industrial applications. estimation starts ...

Gas injection volume is the key parameter of air drilling with raise boring machine, and determination minimum gas one technologies to improve speed shorten period. Based on characteristics technology, construction technique as circulating medium studied, double-channel structural direct circulation system are discussed. On basis summarizing analyzing principle calculation methods, required for...
