Aeromodelismo e Oxigénio

Eis um Objcto que pode servir de inspiração a muito Modelista, um Painel de Controlo para um Modelo de Avião feito através da Sculpteo:

Eis o Avião, do qual o Modelo foi feito:

Aeromodelling – 3D Printed Plane Dashboard Replica 
Posted on 2011/09/02 by sculpteo 
User “Tortilla”, from Dijon Flying Club, modeled this Robin DR400 dashboard ready to be 3D Printed. “The Robin DR400 is a wooden sport monoplane, conceived by Pierre Robin and Jean Délémontez. The Robin DR400 first flew in 1972 and was still in production in 2008. It has a tricycle undercarriage, and can carry four people. The DR400 aircraft have the ‘cranked wing’ configuration, in which the dihedral angle of the outer wing is much greater than the inboard, a configuration which they share with Jodel aircraft. This model is considered easy to fly by many and quiet during flight due to its wooden frame” (Wikipedia)

Miniature oxygen generator implants to boost effectiveness of cancer treatments 

By Darren Quick 

Some cancers, such as pancreatic and cervical cancers, are notoriously hypoxic, which means they contain low oxygen levels. Because radiation therapy needs oxygen to be effective, hypoxic areas of a tumor can be difficult to kill. To combat this, researchers at Purdue University have developed and tested a miniature electronic device that is designed to be implanted into solid tumors to generate oxygen and boost the effectiveness of radiation and chemotherapy treatments. Once implanted into a tumor, the new "implantable micro oxygen generator" uses ultrasonic signals to generate a small voltage to separate oxygen and hydrogen from water in a chemical process called water electrolysis. The devides are just under one centimeter (0.39-in) long and are inserted into tumors with a hypodermic biopsy needle.
