Dr. László Végh (born in 1931), composer and radiologist played a decisively influential role in forming of the underground art scene of the Sixties. He presented (from 1958) the first local examples of concrete and electronic music compositions for the living representatives of Hungarian modernism and for the new generation of the neo-avant-garde in the quasidemocratic communities of private spaces. Due to this mediating cultural activity, his non-conformist personality and appearance, impressive network across the generations, Dr. Végh offered a new model of alternative living and the continuity of modernism behind the iron curtain. His soirées and proto-actions — for which I would introduce the term ‘intuitive actions’ – were performed with young artists of the subculture, and led to deconstruction of traditional art forms through pieces of avant-garde and experimental music, while opened up the way for happening and fluxus.
A program is described which enables performing of genetic algorithms for the determination of two positive real parameters.
These new types of procedures are tested on a software of determination of flame temperatures previously developed in a fully
classic way. The genetic operators used are crossover and mutation. They perform operations on a binary coded form of the
parameters. The goal of the present study consists in developing and optimizing a genetic determination of the parameters
at a given temperature. We succeed in selecting the general architecture of the procedure and implementing it in our main
software of calculation of flame temperature. We have chosen this pyrotechnic field of application because we knew the behaviour
of the real parameters, so the debugging operations were easier.

A report is given on the various research activities concerning radioanalytical chemistry performed in the following fields;
(a) radiochemistry; (b) non-nuclear methods; (c) instrumental neutron activation analysis; (d) computer analysis of γ-ray
spectra. All these activities are carried on in the frame of two surveys extended to the whole Italian territory: the first
one on the radioactive environmental contamination both of natural and of artificial origin; the second one on a number of
non-radioactive trace elements, with a particular emphasis upon their presence, as contaminants, in the food-chain and upon
their uptake by man.

In this study we show that the NAA technique can be used to perform clinical analyses of blood and urine, with many advantages towards the conventional methods. From the knowledge of the neutron flux and the induced activity, the concentration ofelements were obtained. In comparison to the conventional techniques, this methodology uses smaller quantities of biological material and allows the simultaneous evaluation of the concentrations of several elements in biological samples at once, something not always possible in the conventional clinical analysis. Another important advantage is that it eliminates the use of standard materials, thus making the analyzing process practical and economic.

With the introduction of falloposcopy, an in vivo image of the inner surface of the Fallopian tubes has become available. The tubal factor in subfertile couples also provides specific, clinically relevant, and valuable prognostic information by clearly demonstrating the presence or absence of even minor anatomical abnormalities. We introduced falloposcopy to our clinical practice at the end of 1999.
To perform tuboscopy in the evaluation of infertility.
Patients and methods
The examination was performed under general anesthesia, using the transcervical (via hysteroscopy) “guide wire” catheterization system and a 0.5-mm falloposcope with 3000 pixels, under laparoscopic control. We attempted this examination in 22 cases.
Differences were found in the falloposcopic image and in the previous finding of hysterosalpingography. We succeeded in cannulating the Fallopian tube even in cases with intramural occlusion showed by hysterosalpingography. In our series, fever was not observed and only one perforation occurred. Submucosal interstitial edema was observed in one of the Fallopian tubes. The mean operational time including the cervical dilatation, hysteroscopic procedure, and laparoscopic CO2 insufflation was 50 min.
After the first introduction of falloposcopy in Hungary, we need to find its place in evaluating infertility and to discuss its indication. Furthermore, the technical difficulties should also be taken into consideration. We recommend incorporating the falloposcopic examination into the screening of infertility.
