Performance Analysis and Design of a Robotic Fish for In-Water Monitoring by Wenwen Yuan, Shaonan Hao, Zhiqiang Liu, Feng Zhou, Youchao Wu

“…In this study, a bionic greenfin fish robot is designed in detail, and a hydrodynamic simulation analysis of the designed bionic greenfin fish robot is carried out using STAR CCM+ and Fluent software to analyze the effects of different parameters on the propulsion performance of the pectoral fins, the steering of the caudal fins, and the emergency stop function. The swimming efficiency was found to be highest when the angle of attack was changed sinusoidally by 10° and the frequency was the same as that of the pectoral fin flutter. …”

Modern Tendencies in the Treatment of Strabismus in Children by E. Yu. Markova

“…A particularly difficult problem is forms of strabismus: paralytic, alphabetical (V, A, X) and other syndromes ( Duane, brown DVD, etc.) in which involved in the pathological process not only the muscles of the horizontal and vertical actions, but also one of the causes are functional disorders. In the syndrome of “V” and converging strabismus, the angle of deflection decreases when you look up and increases when looking down; in case of divergingstrabismus, the deviation is more when you look up and less when looking down. …”
