PSR B1919+21 is a pulsar with a period of 1.3373 seconds [4] and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell on 28 November 1967, it is the first discovered radio pulsar. [5]
Nightingale's theory was shown to be applicable during the Crimean War when she, along with other nurses she had trained, took care of injured soldiers by attending to their immediate needs, when communicable diseases and rapid spread of infections were rampant in this early period in the development of disease-capable medicines.
Ida Jean Orlando (August 12, 1926 – November 28, 2007) was an American nurse whose theory has significant relevance for nursing in many countries worldwide. [1]Orlando graduated as a nurse from New York Medical College in 1947.
Though some nurses and doctors were beginning to become skeptical of the miasma theory in the 19th century, there were no other prevailing explanations for epidemics and infections. Florence Nightingale, Ignaz Semmelweis, and John Snow understood that people could get sick from objects, water, or hands that were contaminated by bodily fluids or ...
This coupling is measured by the relative linear growth- or decay rate κ of the amplitude of a given normal mode in one pulsation cycle (period). For the regular variables (Cepheids, RR Lyrae, etc.) numerical stellar modeling and linear stability analysis show that κ is at most of the order of a couple of percent for the relevant, excited ...
In fluid dynamics, a flow with periodic variations is known as pulsatile flow, or as Womersley flow.The flow profiles was first derived by John R. Womersley (1907–1958) in his work with blood flow in arteries. [1]
Werner Theodor Otto Forßmann (Forssmann in English; German pronunciation: [ˈvɛʁnɐ ˈfɔʁsˌman] ⓘ; 29 August 1904 – 1 June 1979) was a German researcher and physician from Germany who shared the 1956 Nobel Prize in Medicine (with Andre Frederic Cournand and Dickinson W. Richards) for developing a procedure that allowed cardiac catheterization.
In fact, despite multiple suitors, she never married for fear it might interfere with her calling for nursing. Albert Finney referred to the effect as the "Florence Nightingale syndrome" in a 1982 interview, [ 1 ] and that phrase was used earlier to refer to health workers pursuing non-tangible rewards in their careers.
