Viscosities of melts in the Na2O---FeO---Fe2O3---SiO2 system and factors controlling relative viscosities of fully polymerized silicate melts [PDF]

open access: yes, 1988
Na2O---B2O3---SiO2 and Na2O-Ga2O3 viscosities decrease in the order aluminosilicate > ferrosilicate, (galliosilicate ?) > borosilicate. Thp electronegativities of the trivalent cations are inversely correlated with the relative viscosities of melts in ...

Effects of Combined Sorbitan Monolaurate Anti-Agglomerants on Viscosity of Water-in-Oil Emulsion and Natural Gas Hydrate Slurry

open access: yesEnergies, 2017
Hydrate plugging is the major challenge in the flow assurance of deep-sea pipelines. For water-in-oil emulsions, this risk could be significantly reduced with the addition of anti-agglomerants (AAs).

Observations of viscous magnetization in multidomain magnetite [PDF]

open access: yes, 2006
The viscous behavior of multidomain magnetite has been directly observed in both natural and synthetic samples using Bitter pattern imaging. A computer-controlled fully automated microscope fitted with a heating stage, field coils, and digital camera was

Viscosity method for hierarchical variational inequalities and variational inclusions on Hadamard manifolds [PDF]

open access: yesJournal of Inequalities and Applications, 2021
AbstractThis article aims to introduce and analyze the viscosity method for hierarchical variational inequalities involving aϕ-contraction mapping defined over a common solution set of variational inclusion and fixed points of a nonexpansive mapping on Hadamard manifolds.

Understanding viscous magnetization of multidomain magnetite [PDF]

open access: yes, 2006
Viscous magnetization (VM) and viscous remanent magnetization (VRM) have been measured, as a function of temperature, between room temperature and the Curie temperature using a suite of well-characterized synthetic and natural multidomain (MD) magnetite ...

Empirical models for viscosity variation in bulk free radical polymerization [PDF]

open access: yesHemijska Industrija, 2004
The validity of the Lyons-Tobolsky equation for bulk polymerization systems was verified by comparing simulation results to experimental data for different reaction conditions (temperature and initiator concentration). In this model, formerly applied for

Individual differences in AMY1 gene copy number, salivary α-amylase levels, and the perception of oral starch. [PDF]

open access: yesPLoS ONE, 2010
The digestion of dietary starch in humans is initiated by salivary α-amylase, an endo-enzyme that hydrolyzes starch into maltose, maltotriose and larger oligosaccharides.
