Hypersonic viscous flow over an inclined wedge with heat transfer
The hypersonic viscous flow over an inclined wedge with heat transfer has been investigated by a generalized von Karman integral method for the boundary layer equations of a compressible fluid. With the introduct...

An Evaluation of the Thermal Rossby Number in the Pleistocene
The variations in incoming solar radiation (outside the earth’s atmosphere) produced by changes in the eccentricity of the earth’s orbit, earth obliquity and longitude of perihelion have been recalculated for ...

Heuristic Techniques for Solving Large Combinatorial Problems on a Computer
Many problems of optimization, search, or decision-making are combinatorial in nature and basically non-numerical. The advent of the modern high-speed digital computer has opened the way for us to solve many o...

Influence of Morphology on the Viscoelastic Behavior of a Solvent-Cast S-B-S Block Copolymer
It has recently been demonstrated in the literature that styrene block copolymers give rise to different morphological structures depending on the condition of sample preparation. Thus polymers cast from benze...

Nonlinear Optical Effects
Third-harmonic generation in cholesteric liquid crystals, far-infrared generation by ultrashort pulses, and self-focusing of light in nonlinear media are taken as examples for illustration of nonlinear optical...

Interfacial Morphology and Autohesion of A-B-A Triblock Copolymers
The tensile-recovery response, optical transparency, and autohesion properties of an A-B-A triblock copolymer where A is polystyrene and B is polybutadiene have been analyzed in terms of the interfacial mechan...

Weighting Function Estimation in Distributed-Parameter Systems
An accelerated stochastic approximation algorithm is developed for the identification of weighting function associated with boundary control in one-dimensional linear distributed-parameter systems. The weighti...

Thermoelasticity of Crosslinked Rubber Networks
In recent publications we have demonstrated that by using a new equation, which is based on the temperature coefficient of shear modulus, the relative energy contribution (fu/f) to rubber elasticity can be shown ...

Chapter
Catecholamines and 5-Hydroxytryptamine
Numerous attempts have been made to implicate the pharmacologic effects of morphine or its surrogates with the biogenic amines in the brain. Such premises are the natural consequences of the facts that the ami...

Studies on the Mode of Action of Non-Steroidal Anti-Inflammatory Agents
The recent proposal by Vane and his associates at the Royal College of Surgeons in London (Vane, 1971; Smith and Willis, 1971; Ferreira et al, 1971) that the antiinflammatory activity of indomethacin may be relat...

Viscoelastic and Dielectric Properties of A-B-A Type Block Copolymers
The viscoelastic and dielectric properties of two A-B-A type block copolymers were determined. One contains styrene-butadiene- styrene (SBS) blocks and the other styrene-isoprene-styrene (SIS) blocks. Samples ...

Chapter
Nonequilibrium Phenomena in Cryogenic Two-Phase Flow
Analytical solutions are rare in two-phase flow problems, and for many practical ases empirical methods are used. Lockhart and Martinelli [1] applied an empirical correlation to the flow of air-water mixtures. Ma...

Chapter
Time-Temperature Superposition in Heterophase Block Copolymers
The viscoelastic behavior of a styrene-butadiene-styrene block copolymer cast from several different solvents was studied in order to examine the validity of the time-temperature superposition principle in het...

Concentration Dependence of the Kondo Effect in a Random Impurity Potential
In a recent paper Tsay and Klein1,2 examined the two-impurity Kondo effect3 in the presence of an s—d Hamiltonian4,5 and an impurity—impurity exchange interaction of the form W01S0 · S1where W 01 ...

Effect of Do** on the Resonance Raman Scattering in InSb Near the E1 Transition
Resonant Raman Scattering (RRS) of highly doped InSb at the E1 transition has been measured. Increase in impurity concentration broadens and shifts the RRS peaks towards lower energies and changes the peak height...

Exciton Enhanced Raman Scattering of LO Phonons in Trigonal Se
Resonance enhancements in the Raman cross-section of longitudinal optical (LO) phonons in trigonal Se have been measured around its excitonic absorption edge at low temperatures. Our results are explained in t...

The Scattering of Low-Energy Helium Atoms at the Surface of Liquid Helium
We have designed an atomic beam experiment to be performed at low temperature in order to study the scattering of helium atoms at the liquid surface. This work has been partly stimulated by the theoretical pap...

Recent Experiments on the Surface of Liquid 4He: Elastic Scattering of 4He Atoms
The first part of the paper concerns the experimental determination of the two-dimensional effective interaction potential between 3He atoms adsorbed on the surface of liquid 4He. Measurements of the velocity of ...

Stimulated Raman Scattering
Stimulated Raman scattering was accidentally discovered by Woodbury and Ng in 1962 [7.1]. In studying Q-switching of a ruby laser by a nitrobenzene Kerr cell, they detected intense infrared radiation emitted from...

Comment
In my opinion, there is clear physical distinction between resonant Raman scattering (RRS) and hot luminescence (HL) if we believe there is clear distinction between transverse and longitudinal resonant excita...
