Summary form only given. Dermatophytes are the most common aetiological agents, which invade into keratinized tissues (skin, hair, nails) of humans and animals causing dermatophytosis (also known as ringworm or tinea). Swimming pools, fitness centers, barber shops, beauty parlors, saunas and steam baths are common places to pick up superficial fungal infections. Mycotic infections have become more...
Summary form only given. Aqueous environments are susceptible to contamination by bacteria, protozoa and viruses, which are the root cause of various illnesses. These contaminations are usually treated by chemical methods. Recently, attempts have been made to inactivate bacteria in water with non-thermal plasmas using various approaches, e.g., a pulsed streamer discharge plasma or a gliding arc discharge...
Optical emission spectroscopy and fast, time-resolved imaging are used to assess the plasma parameters in the plasma channel of a pulsed power electrical discharge in gas bubbles. Gas bubbles are produced at the tip of a needle electrode submerged in water. The discharge in Ar, O2, and air bubbles is generated by applying 1 ??s long, 8-20 kV rectangular voltage pulses to the needle electrode. Spectroscopic...
Summary form only given. Electrical discharges in gas bubbles in water are investigated by applying microsecond long rectangular pulses of 6-20 kV to needle-to-plane electrodes submerged in water. Ar or O2 bubbles; 1-5 mm in diameter, are introduced through the Pt needle that serves as the negative electrode. A bubble remains on the needle through numerous discharge processes. The voltage across the...
