It has been shown that a nonchiral anisotropic macromolecule embedded in a chiral dielectric solvent possesses an effective optical activity proportional to the optical activity of the solvent.As a result, there exists an effective chiral interaction between the macromolecules, which creates a B-12 Methylcobalamin torque acting on the primary axes

This paper presents a numerical model for the smart detection of synchronous and parametric roll resonance of a ship.The Seats model implements manoeuvring equations superimposed onto ship dynamics in waves.It also features suited autopilot and rudder actuator models, aiming at a fair depiction of the control delay.The developed method is able to i

Micromechanical oscillators provide periodic output signals for clocks and sensors by vibrating in a single mechanical mode.The mode is conventionally excited into self-sustained oscillations and stabilized with an external electronic feedback loop.A paradigm is emerging for sustaining vibrations by coupling the mechanical mode with internal degree
