Histoire d'une greffe | La main d'Arja | ARTE
Arja, a patient who lost both hands and feet to septicemia following a minor cut and a broken rib, undergoes a complex double hand transplantation in Finland. The procedure involves microsurgical reattachment of bones, blood vessels, nerves, and tendons, followed by an intensive rehabilitation protocol to restore dexterity. Arja's recovery includes psychological adaptation to the new limbs and the development of a specific list of functional goals, such as using a power drill or applying makeup. The medical team manages high risks of rejection through strict anti-rejection treatments and coordinates a rapid response system for donor alerts to ensure surgical success within a 30-hour window.
Los Microondas Podrían Calentar Más... Pero Sería Ilegal
Operating microwave ovens at higher frequencies like 20 GHz instead of the standard 2.45 GHz would be illegal due to interference with mobile and GPS signals, as commercial devices are restricted to specific ISM bands. While increased frequency would theoretically allow water molecules to absorb more energy, the resulting waves would penetrate food too shallowly, causing burnt exteriors and cold interiors. Consequently, regulatory constraints and physical limitations make higher frequencies impractical for domestic cooking despite their potential energy absorption. The current 2.45 GHz standard balances legal compliance with effective heating depth to ensure food is cooked evenly.
