Structure and IR Spectra of 3(5)-Aminopyrazoles and UV-induced tautomerization in argon matrix

The prototropic tautomerism in 3(5)-aminopyrazoles was investigated by matrix isolation infrared (IR) spectroscopy, supported by DFT(B3LYP)/6-311++G(d,p) calculations. In consonance with the experimental data, the calculations predict tautomer 3-aminopyrazole (3AP) to be more stable than the 5-aminopyrazole (5AP) tautomer (calculated energy difference: 10.7 kJ mol−1 ; Gibbs free energy difference: 9.8 kJ mol−1 ). The obtained matrix isolation IR spectra (in both argon and xenon matrices) were interpreted, and the observed bands were assigned to the tautomeric forms with help of vibrational calculations carried out at both harmonic and anharmonic levels. The matrix-isolated compound (in argon matrix) was then subjected to in situ broadband UV irradiation (λ > 235 nm), and the UV-induced transformations were followed by IR spectroscopy. Phototautomerization of the 3AP tautomer into the 5AP form was observed as the strongly prevalent reaction.UI0313B/QUI/2020, UI0313P/QUI/2020info:eu-repo/semantics/publishedVersio

System sonares extension for extreme cases

Statistics shows that in cases of natural disasters, catastrophes and accidents about 70% of affected persons need specific healthcare approach limited in time. In all these cases the people life-saving depends on the actions of emergency services. Net of the centers of urgent medical help assures the assistance which is efficient enough in the cases when the number of victims is not large. But if the number of victims is large (mass casualty and disaster setting) the new methods are necessary which will determine quickly the lesion location, first aid measures at the place of accident and the help that should be provided for victims to be transported to specialized clinics. To assure adequate and efficient measures of providing of urgent medical help to victims the efficient on-the-fly diagnostics methods are necessary

Device for command and controlling of temperature in stratification installations

În curs de brevetare.Dispozitivul conţine un traductor de temperatură şi un bloc de comandă cu încălzitorul. Funcţionarea dispozitivului se bazează pe măsurarea temperaturii compusului care înlocuieşte solul şi comanda cu încălzitorul de tensiune joasă. Astfel, este exclusă supraîncălzirea zonei altoirii pomilor şi este asigurată o dinamică prestabilită a temperaturii de tratament. Este confecţionat în baza unui microcontroler din familia ATmega şi traductor de temperatură digital DS18B20, conţine un panou de comandă asamblat prin metoda Q-touch. Urmăreşte ruptura sau scurtcircuitul în circuitul încălzitorului, generează semnale sonore şi luminoase de alarmă. Este posibil de utilizat în regim de funcţionare autonom sau în componenţa unei reţele locale.The device is consisted of a temperature sensor as well as a block for controlling the heater. The device operation is based on temperature measurement of substitute soil and control of low voltage heater.
