Investigation of Rotor Efficiency with Varying Rotor Pitch Angle for a Coaxial Drone
Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line.

Role of synaptic structural plasticity in impairments of spatial learning and memory induced by developmental lead exposure in Wistar rats. [PDF]
Lead (Pb) is found to impair cognitive function. Synaptic structural plasticity is considered to be the physiological basis of synaptic functional plasticity and has been recently found to play important roles in learning and memory.

Atomic Structure Calculations for Pb+70 and Pb+71
This paper describes a detailed theoretical analysis of energies, Lande g-factors, lifetimes for excited levels, and wavelengths, transition probabilities, and weighted oscillator strengths for electric dipole transitions for Mg- and Na-like lead. Recently, the accurate atomic knowledge of highly ionized heavy atoms has been attractive for many fields,

The Magnetic Entropy Changes in Pb Doped Ni-Mn-Cu-Ga Alloys [PDF]
Effect of Pb addition on magnetocaloric properties of Ni50Mn18,75Cu6,25-aPbaGa25 (a = 1, 2, 3, 4, 5) alloys was investigated experimentally. The magnetic measurements conducted at low field of 4 kA/m showed that addition of Pb led to separation of the ...
