Development of experimental procedure - GDV process standardisation

DEVELOPMENT OF EXPERIMENTAL PROCEDURE

GDV process standardisation
Various approaches and principles of Kirlian diagnostics have been developed in the world over the recent decades.

Difference between the approaches used, inconvenience of photoprocessing, darkening necessity and, above all, lack of quantitative criteria have hindered from serious application of the method to medicine and biology.

One of the steps in this direction is the standardisation of techniques, which use different methods (photo, xerox, TV). This approach is based on computer image processing for quantitative estimation of the image parameters. Thereby, we will be able to compare the results of several investigators. It is inexpedient to introduce restrictions on the applied frequencies, amplitudes or design of devices and methods of processing, it is advisable to search for the basis of comparison. Therefore, it is much better to develop the technique of comparison of the final result - the most gas-discharge image.

The standardisation task is to calculate the GDV image parameters of the test-object by means of standard computer processing and to estimate the state of Visualisation system as a single whole, including all its components. To accomplish this task it is necessary to choose standard object for visualisation and standard method of assessment.

Standard object should meet the following requirements:

Stable, invariable in time characteristics;
Independence from the environment;
Working convenience;
Simple parameters control;
Simple reproducibility (copying possibility);
Stability within the gas discharge, making maximum use of the parameters.

The research object selection.
Selection of various test-objects was carried out. Both metal and dielectric objects were investigated: metal wires, needles, spheres and cylinders, including those filled with the liquid solutions. The GDV-images taken were processed by computer to receive a set of parameters. The visualisation system parameters were kept at the accuracy level of 1%.

As a result of these investigations, it was found out that many materials, of which test-objects are made, change their characteristics in the course of time. This is associated with their oxidation within the GDV process. Hence, such materials can not be used for the production of test-objects, since their characteristics will not be stable and reproducible. Such test-objects do not satisfy the conditions stated above.
It was determined that the optimal test-object is the test-object, consisting of titanium and brass. Results of the experiments made showed that the titanium test-object satisfies all the conditions stated above. Its characteristics are stable and invariable in time. The disadvantage of this metal lies in the fact that it is very light. Therefore, for the test-object production this metal is combined with brass, which is much heavier.
The main subject of interest in the current research was water and liquids'. It was necessary to study water GDV characteristics to determine the level of parameters' stability and reproducibility in the GDV process.

Procedure of the research
In this work the following research types were put into practice:

Study the type of statistics and statistical error of the GDV method based on statistical processing of the GDV parameters of the standard test-object, measured consequently and in different days.
revealing the type of data population distribution according to the typical parameters. The objects for this investigation were distilled water and normal solution of extra-pure NaCl.
revealing statistically significant differences between distilled water, normal solution of extra-pure NaCl and their ionised analogues (10 and 5 times exposed to the GDV electromagnetic field, respectively); determination of the main conditions for GDV research.
revealing statistically significant differences between the solutions of various chemically pure electrolytes (NaCl, KCl, NaNO3, KNO3) under the concentration degree from normal to more than 16000 dilution of normal solution, and also on the problem of revealing the concentrations of these solutions, corresponding to the absence of statistically significant differences between them and distilled water.
Investigations using test-objects and several types of screens for detection of a new principles and development of new devices for GDV study.

The results of these investigations are given below.
GDV images of liquids were obtained with the help of a special device for liquids, in which the liquid was suspended in the form of a drop within 3 mm over the screen surface. All the images were taken by means of a special programme "GDV Grabber".

All the investigations were carried out under temperature span from 22,5 to 23,5oC and relative humidity from 42 to 44%.

All the study work were done with the device "GDV Camera" by "Kirlionics Technologies International".
