We study the properties of compacton-anticompacton collision processes. We compare and contrast results for the case of compacton-anticompacton solutions of the K(l,p) Rosenau-Hyman (RH) equation for l = p = 2, with compacton-anticompacton solutions of the L(l,p) Cooper-Shepard-Sodano (CSS) equation for p = 1 and l = 3. This study is performed using a Padé discretization of the RH and CSS equat...

The solubility of hydrogen in amorphous silica at a temperature of 250 °C and pressures up to 75 kbar is studied using a quenching technique. The molar ratio H(2)/SiO(2) is found to linearly increase with pressure from X = 0.16 at P = 6 kbar to X = 0.53 at P = 75 kbar. An investigation of a sample with X = 0.47 by Raman spectroscopy demonstrated that hydrogen dissolves in silica in the form of ...

In this study, we report on physical and in vitro biological characterization of succinylated collagen (SC). SC was prepared by succinylation of type I bovine tendon collagen. SC swells and dissolves in physiological pH buffers (pH 7.4) Biocompatibility of SC to collagen for fibroblasts was comparable but L6 myoblasts showed pronounced proliferation and differentiation with SC. Using the MALDI-...

Mental and neural states are related to one another by vertical (synchronic) interlevel relations and by horizontal (diachronic) intralevel relations. For particular choices of such relations, problems arise if causal efficacy is ascribed to mental states. In a series of influential papers and books, Kim has presented his much discussed “supervenience argument”, which ultimately amounts to the ...

The different Escherichia coli envelope fractions (cell wall, cytoplasmic membrane, and DNA-envelope complex fragments) were isolated by free-flow electrophoresis and analyzed by sodium dodecylsulfate-acrylamide gel electrophoresis. The DNA-envelope complex fragments possess a specific protein (mol wt 80,000-90,000). Upon treatment with trypsin, this protein disappears and the complex breaks do...

Raphanus sativus L. var niger (black radish) is a plant of the cruciferous family with important ethnobotanical uses for the treatment of gallstones in Mexican traditional medicine. It has been established that the juice of black radish decreases cholesterol levels in plasma and dissolves gallstones in mice. Glucosinolates, the main secondary metabolites of black radish, can hydrolyze into its ...

Geological carbon dioxide (CO2) sequestration entails capturing and injecting CO2 into deep saline aquifers for long-term storage. The injected CO2 partially dissolves in groundwater to form a mixture that is denser than the initial groundwater. The local increase in density triggers a gravitational instability at the boundary layer that further develops into columnar plumes of CO2-rich brine, ...

We review a memory-based buffer model of visual perception, that combines the lower and middle stages in the analysis of video. This model was originally developed for the detection of breaks between physical scene changes (“story units”). In this paper we show how this method can also be applied for shot detection. Moreover, it gives rise to a unified approach for detecting cuts and gradual ch...

A sample of tritiated lanthanum nickel aluminum alloy (LaNi4.25Al0.75 or LANA.75) similar to that used at the Savannah River Site Tritium Facilities was analyzed to estimate the particle size distribution of this metal tritide powder and the rate at which this material dissolves in the human respiratory tract after it is inhaled. This information is used to calculate the committed effective dos...

The use of natural gums, taken from the exudates and extracts of plants, has been given a strong impulse due to both the many and lucrative possibilities for industrialization and to the excellent international market. A gum or resin of a yellowish color, soluble in water, and which presents a great potential for industrialization, appears on the trunk and branches of the cashew tree; that is k...
