Perron's method for viscosity solutions of semilinear path dependent PDEs [PDF]

open access: yesarXiv, 2015
This paper proves the existence of viscosity solutions of path dependent semilinear PDEs via Perron's method, i.e. via showing that the supremum of viscosity subsolutions is a viscosity solution. We use the notion of viscosity solutions introduced by Ekren, Keller, Touzi and Zhang, in whose work all smooth processes which are tangent in mean are ...

Stimuli-sensitive hydrogels: A novel ophthalmic drug delivery system

open access: yesIndian Journal of Ophthalmology, 2010
Background: Stimuli-sensitive hydrogels are three-dimensional, hydrophilic, polymeric networks capable of imbibing large amounts of water or biological fluids on stimulation, such as pH, temperature and ionic change.

Experimental study on the relationship between extensional and shear rheology of low-viscosity power-law fluids [PDF]

open access: yesarXiv
This paper investigates the relationship between extensional and shear viscosity of low-viscosity power-law fluids. We show the first experimental evidence of the conditions satisfying the same power exponents for extensional and shear viscosity, as indicated by the Carreau model.

Predicting the glass transition temperature and viscosity of secondary organic material using molecular composition

open access: yes, 2017
. Secondary organic aerosol (SOA) accounts for a large fraction of submicron particles in the atmosphere. SOA can occur in amorphous solid or semi-solid phase states depending on chemical composition, relative humidity (RH), and temperature.

SIGNIFICANCE OF VISCOSITY OF VISCOSE IN RAYON INDUSTRY

open access: yesSen'i Gakkaishi, 1958
The degree of polymerization of alkali cellulose which is ready to be used for xanthation is very important in relation to the quality of the product. A series of experiments was carried out on semi-commercial of scale to find the effects of alkali cellulose prepared for xanthation upon viscosity of viscose and various properties of filaments.1.

Caracterização do suco de araçá vermelho (Psidium cattleianum Sabine) extraído mecanicamente e tratado enzimaticamente = Characterization of red araçá juice (Psidium cattleianum Sabine) mechanically extracted and enzymatically treated

open access: yesActa Scientiarum: Agronomy, 2007
A partir do fruto de araçá vermelho, elaboraram-se dois tipos de sucos, mediante processamento mecânico, em que se obteve o suco S-1 e após tratamento enzimático de S-1 obteve-se o suco S-2, os quais foram analisados e monitorados durante quatro meses ...

Towards Sustainable Viscose-to-Viscose Production: Strategies for Recycling of Viscose Fibres

open access: yesSustainability
The potential for using discarded viscose textiles to produce high-quality viscose fibres is limited by the low molecular weight of the cellulose and its continued reduction in the recycling process. Herein, we present a straightforward approach of reprocessing discarded viscose textiles while achieving high-quality recycled viscose fibres.
