Bu Buda & Pest- the charming twins on the banks of Danube

The international airport was going through refurbishing when we flew into Budapest in October 2019. We had to directly walk across to the terminal after deboarding our flight - rather literally rush in the face of soft sprays of drizzles and cold wind on our way. Strange it may seem, but on our left, a long chain of passengers was moving towards their boarding gate housed in a small temporary cubicle. They were separated from us by a barricade made of wire mesh. A scene identical to images of European Jews being herded by the Nazis for deportation by holocaust trains. Outside, Mr. Gabor (one of the partners of Lichtenstein Apartments) was waiting to pick us up as our apartment was about 15 km away from the airport. Lichtenstein Apartment complex is centrally located, on a lane leading to the hub of Jewish Quarters in District 7. The apartments are cut out from century-old building interiors with very high ceilings and tall w…

An Invisible War – Overview on the role of UV-C in fighting COVID-19

UV-C vs COVID 19 The invisible pathogen COVID 19 has suddenly taken our entire planet by surprise at the beginning of 2020. The invasion was so sudden that even the World Health Organization (WHO) took time to declare this as a pandemic. At a time when the entire world is trying to arrive at plausible solutions to arrest the spread of this rampaging virus, our Lighting fraternity has joined the fight by concentrating more on studies of non-visual impacts of light. An invisible part of the optical radiation spectrum, ultraviolet radiation has more energy than its visible counterpart due to its shorter wavelengths. The ultraviolet spectrum comprises UV-A (400 nm to 315 nm); UV-B (315 nm to 280 nm); UV-C (280 nm to 100 nm) – classification as defined by CIE. Whenever ultraviolet radiation is used for germicidal purposes, it is known as GUV (Germicidal Ultraviolet ) radiation. It has been found to be highly effective in deactivating or killing viruses, bacteria, fung…
