Modeling Meridians Within the Quantum Field Theory
Larissa Brizhik,Enrico Chiappini,Patrizia Stefanini,Giuseppe Vitiello 사단법인약침학회 2019 Journal of Acupuncture & Meridian Studies Vol.12 No.1
We present here a model of meridians in the formalism of the gauge theory paradigm of quantum field theory with spontaneous breakdown of symmetry. We discuss the origin and dynamic self-focusing propagation of the electromagnetic field in coherent states and the role it plays in our meridian modeling. Within this frame, we consider the formation of solitary waves on proteins and anatomical filamentary structures and discuss nondissipative energy transport. Finally, we analyze the relation of meridians with anatomical filamentary structures, the reciprocal actions between meridians, and biochemical activity and the key role played by free energy, internal energy, and entropy.

Electrospun hybrid TiO2/humic substance PHBV films for active food packaging applications

Sustainable packaging materials can play a key role in minimizing the environmental footprint of packagedfood by preserving its quality and avoiding environmental persistence of plastic waste. Waste towealth approach can cope with these major challenges by providing for bioavailable active compoundsfrom waste residues. To this regard, humic substances (HS), derived from biowaste oxidative processes,exhibit intrinsic antioxidant and antimicrobial features, which can be significantly boosted by molecularcombination with an inorganic nanostructured phase. Herein, this approach has been integrated with theelectrospinning technology to design composite films made of electrospun biodegradable and bioderivedpolymers filled with nanostructured hybrid HS based materials. Therefore, electrospun composites madeby including hybrid TiO2_HS nanostructures into PHBV matrix were first produced and then convertedinto homogeneous and continuous films to obtain an active layer which will be part of a multilayer foodpackaging solution. These were characterized in terms of morphology, thermal, crystallinity, optical,mechanical and barrier properties as well as antimicrobial performance against Staphylococcus aureusand Escherichia coli, two main strains of food pathogens. The results suggested that the combination ofhybrid nanomaterials with electrospinning methodology is a promising and sustainable approach to convertbiowaste into multifunctional materials for active packaging.
