Economic dynamics

A literature survey focusing on the dynamic aspects of von Neumann and Ramsey deterministic many-commodity models. The main emphasis is on topics related to the existence, characterization, and asymptotics of various classes of paths.Translated from Itogi Nauki i Tekhniki, Seriya Sovremennye Problemy Matematiki, Vol. 19, pp. 59–110, 1982.     

Laser-Induced Photodissociation of Carboxyhemoglobin for the Purpose of Treatment of an Organism Poisoned with Carbon Monoxide

The action spectra of the complex of hemoglobin (Hb) with the ligand CO in cutaneous blood vessels have been determined. It is proposed to use the photodissociation of the HbCO complex for elimination of the poisoning action of the CO gas. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 3, pp. 422–424, May–June, 2005.     

Picosecond spectroscopy of dye solutions

Using picosecond spectroscopy technique the rotational relaxation time of rhodamine 4C in solutions both in the ground and excited states is measured to be the same and equal to 250 ps.

While anti-Stokes exciting of non-substituted rhodamine ethanol solution by a single 530 nm picosecond pulse, the blue shift of the gain spectrum on 6 nm over 350 ps after excitation was observed, the process being explained by the orientational solvate relaxation.     

Effect of strokes shift on the operating frequency of lasers

A probabilistic technique is used to compute the dependence of the generating frequency on the Stokes shift in the absorption and emission spectra of materials. It is shown that the generation frequency can vary over a broad range with varying resonator Q.     

The effect of an external mirror on the characteristics of an N2 laser-pumped distributed feedback dye laser

The effect of an external mirror on the DFB dye-laser parameters was investigated experimentally. When a 100% mirror was used, the output energy quadrupled, the divergence decreased to the diffraction limit. Besides the study of the improvement of laser parameters, the temporal behaviour of the amplified spontaneous emission and the DFB dye-laser action were simultaneously investigated.
