Ultraviolet: Code 044 (ウルトラヴァイオレット:コード044, Urutoravaioretto: Kōdo Zero Fōtī Fō) is a Japanese anime television series loosely based on the 2006 science fiction film Ultraviolet, written and directed by Kurt Wimmer, and broadcast from July to September 2008.
Capillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional rheometers, this technique does not involve active stretch or measurement of stress or strain but exploits only surface tension to create a uniaxial extensional flow.
Rheometry (from Greek ῥέος (rheos) 'stream') generically refers to the experimental techniques used to determine the rheological properties of materials, [1] that is the qualitative and quantitative relationships between stresses and strains and their derivatives.
Seven Seas Entertainment licensed the manga in English and began releasing the series in North America starting with the first volume in June 2011. [3] Railgun was adapted as a 24-episode anime television series by J.C.Staff, which aired in Japan between October 2009 and March 2010, followed by an original video animation on October
It is often used for characterizing polymer solutions. Extensional viscosity can be measured using rheometers that apply extensional stress. Acoustic rheometer is one example of such devices. Extensional viscosity is defined as the ratio of the normal stress difference to the rate of strain. For uniaxial extension along direction : [2]
Acoustic rheometer measures sound speed and attenuation of ultrasound for a set of frequencies in the megahertz range. These measurable parameters can be converted into real and imaginary components of longitudinal modulus. Sound speed determines M', which is a measure of system elasticity. It can be converted into fluid compressibility.
Thus, a rheometer can be considered as a special type of viscometer. [1] Viscometers can measure only constant viscosity, that is, viscosity that does not change with flow conditions. In general, either the fluid remains stationary and an object moves through it, or the object is stationary and the fluid moves past it.
