Abdominal thrusts and upwards". They argue that this may be easier to perform with less concern about injury to ribcage or upper abdominal organs. Self-administered abdominal thrusts by study participants produced similar pressures to those generated by first aiders. The highest pressures were produced by participants performing an abdominal thrust onto the back of a chair (115 cmHO). Abdominal thrusts Abdominal thrusts (also called the Heimlich maneuver or Heimlich manoeuvre, ) is a first aid procedure used to treat upper airway obstructions (or choking) by foreign objects. The term Heimlich maneuver is named after Dr. Henry Heimlich, who first described it in
What Is Life? can be viewed as a well-reasoned theoretical prediction of what biologists should have been looking for during their search for genetic material. Both James D. Watson, and Francis Crick, who jointly proposed the double helix structure of DNA based on X-ray diffraction experiments by Rosalind Franklin, credited Schrödinger's book with presenting an early theoretical description of how the storage of genetic information would work, and each independently acknowledged the book as a source of inspiration for their initial researches. The book is based on lectures delivered under the auspices of the Institute at Trinity College, Dublin, in February 1943 and
