The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]
William John Macquorn Rankine FRSE FRS (/ ˈ r æ ŋ k ɪ n /; 5 July 1820 – 24 December 1872) was a Scottish mathematician and physicist. He was a founding contributor, with Rudolf Clausius and William Thomson (Lord Kelvin), to the science of thermodynamics , particularly focusing on its First Law.
The use of preparations similar to opium in surgery is recorded in the Ebers Papyrus, an Egyptian medical papyrus written in the Eighteenth Dynasty. [43] [45] [48] However, it is questionable whether opium itself was known in ancient Egypt. [49] The Greek gods Hypnos (Sleep), Nyx (Night), and Thanatos (Death) were often depicted holding poppies ...
Rankine body an elliptical shape of significance in fluid dynamics, named for Rankine; Rankine scale, an absolute-temperature scale related to the Fahrenheit scale, named for Rankine; Rankine cycle, a thermodynamic heat-engine cycle, also named after Rankine; Rankine Lecture, a lecture delivered annually by an expert in the field of geotechnics
The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It has become the most widely used clinical outcome measure for stroke clinical trials. [1] [2]
In this way, medicine was intimately linked to priests, relegating surgery to a second-class medical specialty. [ 15 ] Nevertheless, the Sumerians developed several important medical techniques: in Ninevah archaeologists have discovered bronze instruments with sharpened obsidian resembling modern day scalpels, knives, trephines, etc.
The expression surgical instrumentation is somewhat interchangeably used with surgical instruments, [27] but its meaning in medical jargon is the activity of providing assistance to a surgeon with the proper handling of surgical instruments during an operation, by a specialized professional, usually a surgical technologist or sometimes a nurse ...
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or to resect and/or connect parts of an organ (e.g. bowels, stomach or lungs). The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close a defect. [1]
