Phase behavior and rheological properties of DNA-cationic
"Rheological properties" most often refers to the Bingham plastic fluid parameters, PV (plastic viscosity) and YP (yield point), as measured by the direct-indicating rheometer. The power-law fluid model parameters, exponent (n) and consistency (k), apply to polymer muds, although the three- parameter Herschel-Bulkley model is a better fit to polymer muds. The science of rheology is increasingly used to describe the properties of fresh cement paste. Compared to standard workability tests, rheological properties allow for more fundamental investigation, more precise phenomenological description of flow properties and serve as input for numerical simulations. The rheological properties of the concrete are changed very significantly by the air entrained agents. The air entrainment increases the cohesion and reduces the tendency of bleeding in the mix. It has been observed that 4 to 6% air entrainment by volume increases the cohesion of the mix and sand content may be reduced by about 5%.

However, most of rheological investigations have been focused on steady shear viscosity and sol-gel transition phenomenon. Based upon the above-described backgrounds, the present study has been undertaken to characterize the rheological 33.

The measurement frequency can also be varied, which provides valuable information about relaxation processes within a sample. (1) Density: The density of a material is defined as its mass per unit volume. Where, ρ is the density is the mass and V (2) Thermal Conductivity: Thermal conductivity is the property of a material that indicates its ability to conduct heat. (3) Enthalphy: The enthalpy of frozen food is related Purpose: To evaluate rheological properties, in vitro dissolution, and in vivo ocular pharmacokinetics of loteprednol etabonate (LE) (submicron) ophthalmic gel 0.38%. Methods: The viscosity of the LE gel 0.38% formulation was measured with a controlled stress rheometer. Dissolution kinetics were evaluated in a fixed-volume and flow-through assay.

Specifically, this type of emulsion which is researched mayonnaise. This instrument is used as an alternative method for rheological properties, while Rheometer Physica MCR 301 and Texture Analyser TA.XT.plus Stable Micro Systems have been used as reference instruments and Simultaneously measure rheological properties and changes in the microscopic structure of a sample with the Thermo Scientific RheoScope Module for the Thermo Scientific HAAKE MARS Rheometer platform. The results allow researchers to speed up formulation development, process optimization and product This polydispersity influences viscosity, overall colloidal stability, and rheological properties of MFC suspensions and gels in aqueous systems. In this work, a systematic rheological analysis is performed for industrially prepared MFC and fractions of different size distributions.
