The Present State of the Problem of the Identification of Kinetic Models

“…The 6200 cm-l tuning range reported by the authors (Martin and Thomas 1967) implied the existence of a continuum extending over this frequency range and mainly on the low-frequency side of the laser. Failure to detect the continuum at that time can now be attributed to the use of semiconductor filters.…”

“…I n a previous paper (Martin and Thomas 1967), the rather low spectral resolution of our equipment led us to the conclusion that the splitting in the tunable output frequency was associated with the Raman frequencies of the non-linear mixing crystal. I n the present work, by using a high resolution spectrograph, we have shown beyond any reasonable doubt that the frequency splitting is, in fact, associated with the Raman frequencies of the liquid in which the continuum is generated.…”

“…Two recent papers (Carman et al 1967, andMartin andThomas 1967) have described tunable frequency sources which have resulted from the selective addition of a laser frequency to a frequency from an intense continuum. The intense continuum was generated by the laser in a liquid which was contained in a cell placed immediately in front of a nonlinear electro-optic crystal.…”

Effects of Glucosamine on Insulin and Glucagon Secretion in Dogs and Ducks

“…Secretion of glucagon is known to increase in a variety of conditions to decrease intracellular glucose utilization, such as starvation (Unger et al, 1963), hypoglycemia (Unger et al, 1962) and following administration of 2-deoxy-glucose and mannoheptulose (Muller et al, 1971). The inhibition of glucose phosphorylation in a-cells may play a role in glucagonogenic the activity of a-cells indirectly (Martin, 1967) by sending the message of glucopenia of the organism to the pancreas.…”

Parametric up-conversion from the infra-red

“…A superior detector for astronomical applications working in the 2.5 to 4.5 /~m region has recently been reported [14]. Optical up-conversion has been used to generate intense, tunable, laser-like radiation in the visible spectrum by up-converting from an I R continumn generated by self-focusing and beam trapping of a neodymium laser beam [39][40][41].…”
