Nonideality in high concentration solutions
… in the implications of true physiological concentrations has led to the development of new tools and techniques. In vivo biological systems differ so significantly from dilute solutions that a model is required to conceptualize them. The excluded volume theory is one such model. In this …

The rheology and flow behaviour of high concentration mineral slurries
The rheology and flow behaviour of high concentration backfill tailings are investigated using a modified Balance Beam Tube Viscometer. The viscometer is capable of producing reliable data using a computer based data acquisition system and three different tube diameters. The aim of this research is …

Enhancing the injectability of high concentration drugs via core annular flows
High concentration drug formulations that can be delivered via subcutaneous injections offer tremendous benefits to global health, but their high viscosity prevents injectability through medical needles. Current approaches to solve this problem face several challenges ranging from cross …

The hydraulic transport of high concentration stabilized flow full plant mineral tailings
… investigation of the flow behaviour of high concentration stabilized mineral tailings used as backfill material. At high solids concentrations "anomalous" behaviour occurs and is indicated by diameter dependancy on rheogram curves. These curves are not coincident in the laminar flow …

Managing complexity in high-concentration flow modelling aimed at hazard assessment: numerical and practical aspects
High-concentration flows are complex phenomena typical of Alpine mountain areas. Essentially, they are free-surface flows with intense sediment transport, often caused by intense rainfall events and involving large volumes of solid material. Because of the amount of sediments moved, the intense …

An analytical and experimental investigation of the hydraulic transport of high concentration mixed regime slurries
… distributions. Slurries of this type with volume concentration up to 50 (relative density of approximately 1.8) are considered.. An analytical model has been developed for such slurries. The inputs to the model are mean mixture flow rate, delivered. concentration and the particle and pipeline …

Response of selected warm-season turfgrasses and ornamental monocots to short-term, high concentration, ozone fumigation
… most powerful oxidants known, is phytotoxic at high levels in the troposphere, or ground-level. Effects of acute ozone exposure for two consecutive days was examined on Bermudagrass (Cynodon dactylon), centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), St. Augustinegrass …

The range of applicability of models for the flow of high concentration backfill slurries in pipelines
… of Cape Town are intended to model the flow of high concentration backfill slurries. These models are the Cooke model for dense phase flow of cyclone classified tailings and the Paterson model for stabilised flow of high concentration full plant tailings. These two materials (cyclone classified …

Increased Utility of pH Sensitive Indicators as High Concentration CO2 Detectors Through the Use of Polyelectrolyte Complexes as Stabilizing Media
… biomedical devices are packaged under high concentrations of carbon dioxide (CO<sub>2</sub>) which can lower the pH of the packaging environment. This is similar to the CO<sub>2</sub> chemistry responsible for ocean acidification.<sup>3</sup> Dye molecules that are sensitive to …

Nonideality of Single and Mixed Electrolyte Solutions Up to Moderately High Concentration; Theory Based on Debye-Huckel Radial Distribution Function
Because of the complex nature of the solvent effect and of the mathematical difficulty in the treatment of the Coulombic long-range force, the theoretical treatments of the equilibrium properties of the electrolyte solution are not fully developed if one compares with those of the non-electrolyte …

Effects of sodium hyaluronate and triamcinolone acetonide on proteoglycan metabolism in equine articular chondrocytes treated with interleukin-1
… this study is to determine if the effects of a high molecular weight sodium hyaluronate (HA) alone or in combination with triamcinolone acetate (TA) can mitigate chondrocyte proteoglycan catabolism caused by interleukin-1 (IL-1) administration. Chondrocytes were collected from fetlock joints of …
