In this work we described the rheological properties of polysaccharides (HBSS, CHSS, DASS, CASS) sequentially extracted from onion (Allium cepa L.). Four onion polysaccharides (ACLPs) solutions resulted into significant differences on their rheological properties.
The rheological (flow) properties of concrete are essential for the construction industry, because concrete, for different elements of a structure, is placed into the formwork while it is in its plastic state.
It is one of the several flow characteristics of drilling fluid, workover fluid or completion fluid or cement. At least two shear rates are used to make measurement of shear stress to define drilling fluid properties. The drilling fluid should have good rheological characteristics for good performance during drilling operation. Rheological properties are important to the design of flow processes, quality control, storage and processing stability measurements, predicting texture, and learning about molecular and The rheological (flow) properties of concrete are essential for the construction industry, because concrete, for different elements of a structure, is placed into the formwork while it is in its plastic state. The rheological property of propellant slurry is the main criterion for the performance of propellant preparation process. Only fuel-rich propellant slurries with low viscosity and yield stress can The rheological properties of liquid food are altered based on the thermal properties such as density, heat capacity and thermal conductivity. The most important factors which determine the properties of liquid food are shear flow properties.
Dynamic shear oscillation measurements at small strain were used to characterize the viscoelastic properties and related differences in the molecular structure of hydrogels based on gelatin methacrylamide. Gelatin was derivatized with methacrylamide side groups and was subsequently cross-linked by radical polymerization via photoinitiation. The light treatment of methacrylamide gelatin A primary experimental method to explore the physical properties of these hydrogels is rheology. A fundamental understanding of peptide hydrogel mechanical properties and underlying molecular mechanisms is crucial for determining whether these biomaterials are potentially suitable for biotechnological uses. In this video, we discussed the rheological properties and the factors that affect on each parameter like plastic viscosity, yield point, gel strength.
RHEOLOGICAL PROPERTIES OF DENTALMATERIALSSMIJAL. The study of flow characteristics of materials is the basis for the science of rheology .
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.
The rheology of the sludge provides information about the capacity and the flow, Accurate knowledge of the rheological properties of sludge requires the

These are based on shear rate and shear stress. In this chapter, rheological properties of foods are discussed, concentrating on the principles of flow behavior and deformation of food systems. The principles of viscosity and texture measurement methods and the devices used in these methods are explained in detail. In addition, models used to understand the rheology of food materials are
To measure the rheological properties of a material, rheometers are used. They measure the torque and the deflection angle of the measuring bob.

The most important factors which determine the properties of liquid food are shear flow properties. These are based on … 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.
The Greek philosopher and scholar, Heraclit (550–480 BC) once said “ πάντα p ɛĩ” (“everything flows”). The rheological property of propellant slurry is the main criterion for the performance of propellant preparation process. Only fuel-rich propellant slurries with low viscosity and yield stress can
The rheological (flow) properties of concrete are essential for the construction industry, because concrete, for different elements of a structure, is placed into the formwork while it is in its plastic state. Rheological properties refer to the Bingham plastic fluid parameters such as yield point (YP) and plastic viscosity (PV).

There are many approaches to evaluate the rheological properties of a waterborne architectural paint. These methods are correlated to different application methods, such as brushing, film formation, leveling, and sagging. Rheological factors including shear rate, shear stress, and flow curve were already measured for different types of waterborne architectural paints. It is well known that the rheological measurements are not direct measuring parameters of flow and leveling.
In addition, models used to understand the rheology of food materials are To measure the rheological properties of a material, rheometers are used.
