Nonthermal Plasma Jet for Biomedical Applications
Low-temperature plasma has been successfully used in medicine for last 15 years. Cure of purulent wounds by means of discharge plasma with low gas temperature is a new method of medical drug-free treatment. A result of investigation of atmospheric pressure helium plasma-jet excited by capacitive discharges at various method of excitation is presented. Homogenous discharge of plasma jet and 34βC of gas temperature at helium flow 0.5L/min was achieved at short pulsed voltage excitation.

Intermediate ultraviolet (UVB) therapy is considered a relatively safe method of treating skin diseases with an autoimmune component in development compared to medical drug methods, including PUVA therapy. This is due to the small depth of penetration of the rays of this wavelength range into skin, which provides a purely local effect on the human body. Excimer lamps are an alternative to the expensive excimer laser for phototherapy of psoriasis or vitiligo. However, for effective phototherapy using UVB lamps, the distance from an emitter to a patientβs skin must be considered. In this paper, we report on treatment of patients using an excimer lamp, the control unit of which is equipped with an optical system for controlling of ultraviolet radiation dose, which allows automatically calculating the time for a set UVB dose. The article describes the results of phototherapy using an excimer lamp of several cases of psoriasis, vitiligo and other forms of dermatitis with a good therapeutic and cosmetic effect. When using an excimer lamp, not a single case of exacerbation of dermatological diseases was established.UVB ΡΠ΅ΡΠ°ΠΏΠΈΡ ΡΡΠΈΡΠ°Π΅ΡΡΡ ΠΎΡΠ½ΠΎΡΠΈΡΠ΅Π»ΡΠ½ΠΎ Π±Π΅Π·ΠΎΠΏΠ°ΡΠ½ΡΠΌ ΡΠΏΠΎΡΠΎΠ±ΠΎΠΌ Π»Π΅ΡΠ΅Π½ΠΈΡ ΠΊΠΎΠΆΠ½ΡΡ

Temperature Distribution of Particles in a Laser Beam
This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered
