Phonons in suspensions of hard sphere colloids: volume fraction dependence.
The propagation of sound waves in suspensions of hard sphere colloids is studied as a function of their volume fraction up to random close packing using Brillouin light scattering. The rich experimental phonon spectra of up to five phonon modes are successfully described by theoretical calculations based on the multiple scattering method. Two main types of phonon modes are revealed: Type A mode...
متن کاملImportance of Particle Size-Fraction Analysis in Suspensions
environmental contamination, including the Barnstable Airport. We agree with Schaider et al. that these exposures may also contribute to the risk of breast cancer, although the earliest data we are aware of show no appreciable levels of volatile halogenated compounds in 1984 BWC water samples (Janik 1987). With only limited historical data available, we cannot be sure of the exact timing and ge...
متن کاملOn the dielectric properties of cell suspensions at high volume fractions
The dielectric increment de’ of the P-dispersion of biological cell suspensions is given (H.P. Schwan, Adv. Biol. Med. Phys., 5 (1957) 147) by the equation Be’ = 9PrC, /4ea, where cells of radius r and of a membrane capacitance C, farads per unit area are suspended at a volume fraction P. This equation predicts that AE’ is proportional to P at all values of P, a prediction which is not borne ou...
متن کاملMixed Mode Fracture in Reinforced Concrete with Low Volume Fraction of Steel Fibers
An investigation into the mixed mode fracture of steel fiber reinforced concrete (SFRC)beams with one percent volume fraction of steel fiber is presented. A series of notched beams withdifferent notch depths and locations are tested under three-point bending. The test results for apparentfracture toughness, crack trajectories, and fracture energy are presented. The crack paths for SFRCand plain...
متن کاملThe Effects of Candida Albicans Cell Wall Protein Fraction on Dendritic Cell Maturation
Back ground: Candida albicans is a member of the normal human microflora. C. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in C. albicans interaction with the host immune system. Major components of C. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...
