Source: Alexander S Rattner; Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA Aircraft, rockets, and ships produce propulsion by accelerating surrounding fluid or high temperature combustion products to high velocity. Because of the principle of conservation of momentum, the increased fluid velocity results in an effective thrust force on the vehicle. The thrust capabilities of propulsion systems are often measured with static thrust tests.

Source: Prashin Sharma and Ella M. Atkins, Department of Aerospace Engineering, University of Michigan, Ann Arbor, MI Multicopters are becoming popular for a variety of hobby and commercial applications. They are commonly available as quadcopter (four thrusters), hexacopter (six thrusters), and octocopter (eight thrusters) configurations. Here, we describe an experimental process to characterize the multicopter performance. A modular small hexacopter platform providing propulsion unit...

This protocol designs a cannula that can be used to control the range of motion for the lifting and thrusting manipulation in acupuncture, thereby improving stability and safety. It can thus serve both the clinical application and scientific research of acupuncture treatment.
FAQs
Forward elevation of the mandible shifts the tongue and other soft tissues away from the posterior pharynx. This enlarges the available upper-airway passage and can relieve obstruction that interferes with ventilation. The maneuver therefore supports airflow during initial assessment and helps create a clearer route for rescue breathing or bag-mask ventilation.
Its key advantage in this situation is that it opens the airway without requiring head extension. By lifting the jaw forward rather than moving the head backward, the rescuer can address upper-airway obstruction while limiting unnecessary cervical spine movement. This makes the technique particularly relevant during emergency airway assessment after possible trauma.
The rescuer places the fingers behind the angles of the mandible and lifts the jaw forward. This directed movement is important because the intended effect comes from advancing the lower jaw and carrying obstructing tongue and soft tissues away from the posterior pharynx. The maneuver should therefore focus on forward mandibular elevation rather than head extension.
During the maneuver, the rescuer positions the fingers behind the angles of the mandible, then lifts the jaw forward without extending the head. The purpose of these steps is to move the tongue and other soft tissues away from the posterior pharynx. Once the airway is opened, the technique can support ventilation or further airway preparation.
Clinicians may use it while assessing an unresponsive patient, attempting rescue breathing, providing bag-mask ventilation, or preparing for advanced airway management. Its role is to improve access through the upper airway before or during these interventions. When cervical spine injury is suspected, the technique is especially useful because it limits unnecessary neck movement while addressing obstruction.
By moving obstructing tissues away from the posterior pharynx, the jaw thrust can improve the passage available for air during bag-mask ventilation or rescue breathing. This may help ventilation reach the patient more effectively and supports oxygen delivery. It can also provide a clearer airway during preparation for advanced airway management in emergency clinical settings.
