Brain surgery has come far from the primitive methods used thousands of years ago.In the last hundred years alone, we have come across countless breakthroughs like the invention of bipolar coagulation, the surgical microscope, microsurgical techniques and a large variety of surgical instruments.The latest years have brought us neuro-navigation, int
Two new species of the genus Parentia Hardy, 1935 from South Africa are described.An identification key to males of seven Afrotropical species Dining Room Tables is compiled for the first time.Parentia magnicornis sp.n.male differs reliably from other Afrotropical species of the genus in enlarged antennal postpedicel and modified 2nd segment of the
An aero-structural algorithm to reduce the energy consumption of a propeller-driven aircraft is developed through a propeller design method coupled with a Particle Swarm Optimization (PSO).A wide range of propeller parameters is considered in the optimization, including the geometry of the airfoil at each propeller section.The propeller performance
