Theoretical and experimental basis of biostimulation
نویسنده
چکیده
There are a great number of mutually contradictory theories attempting to explain the biostimulating effect of laser light; however, none of them provide a scientifically acceptable explanation. This is the main reason why laser light has not come into general use to the extent which its efficiency would seem to deserve. Other reasons might be that a continuously operating laser providing the required output and beam diameter is rather complex, and that special skills are required during handling.

Absorption of DCM Dye in Ethanol: Experimental and Time Dependent Density Functional Study
Experimental and theoretical absorption spectra of [2-[2-[4-(dimethylamino) phenyl]ethenyl]-6-methyl-4H- pyran-4-ylidene]-propanedinitrile (DCM) have been studied. UV-Visible (UV-Vis.) absorption spectrum of DCM has been reported after its synthesis. Two relatively intense peaks appeared at 473 and 362 nm respectively. A theoretical investigation on the electronic structure of DCM is presented ...

متن کاملTheoretical and Experimental Studies of Upright Perforated Wave Filters
Liu et al. (1987) proposed a theoretical solution for scattering of waves through a permeable dissipation region. On the basis of bulk dissipation of the incident wave energy, this method is extended to evaluate the reflection and transmission coefficients of waves through a wave filter composed of rows of perforated sheets aligned normally to the direction of wave propagation. The results of t...

The kinetics of the reactions between triphenylphosphine 1 and dialkyl acetylenedicarboxylates 2, in the presence of a NH-acid such as 5-nitroindazole 3,were studied. Corresponding kinetic parameters to all reactions were evaluated, with the second order rate constant (k) values calculated. Effects of solvent, temperature, and reactant...
