We prove existence and stability results for a two-parameter family of solitary-wave solutions to a system in which an equation of non-linear Schrödinger type is coupled to an equation of Korteweg-de Vries type. Such systems model interactions between short and long dispersive waves. The results extend earlier results of Angulo, Albert and Angulo, and Chen.(More)
Phagosomes were purified from human neutrophils ingesting Salmonella typhimurium opsonized with adsorbed normal human serum or with rabbit IgG. Constituents within the phagosome were endogenously labeled by supplying the cells with 125INa during phagocytosis. Lactoferrin and vitamin B12 binding protein (TC1 and TC3), markers for specific granules, were(More)
Affinity-purified rabbit antibodies specific for collagen types I, III, AB2 and for a partially characterized type IV collagen derived from a murine tumor were used to study the distribution of collagens in the normal mouse kidney. Immunofluorescence staining of conventional frozen sections demonstrated that types I and III were present in bundles around(More)
Periodic monitoring of antimicrobial susceptibility of Neisseria gonorrhoeae is essential for early detection of emergence of drug resistance. A total of 343 gonococcal strains isolated from high-risk and general populations in Bangladesh from 1997 to 1999 were studied. The MICs of penicillin, tetracycline, ciprofloxacin, ceftriaxone, and spectinomycin for(More)
We consider systems of equations which arise in modelling strong interactions of weakly nonlinear long waves in dispersive media. For a certain class of such systems, we prove the existence and stability of localized solutions representing coupled solitary waves travelling at a common speed. Our results apply in particular to the systems derived by Gear and(More)

This study investigated the modification of asphalt with various rubbers and the effect of this modification on the values of fracture toughness at low temperature. Test results indicated that the fracture toughness of asphalt can be substantially increased by modification with a small percent of either a suitable rubber in latex form or with a low(More)
We consider the coupled Schrödinger-KdV system i(u t + c 1 u x) + δ 1 u xx = αuv v t + c 2 v x + δ 2 v xxx + γ(v 2) x = β(|u| 2) x , which arises in various physical contexts as a model for the interaction of long and short nonlinear waves. Ground states of the system are, by definition, minimizers of the energy functional subject to constraints on(More)
