  • irrational
  • The Pythagoreans' conception of number included only what would today be called rational numbers, casting doubt on the validity of the theory in geometry where, as the Pythagoreans also discovered, incommensurable ratios (corresponding to irrational numbers) exist. (wikipedia.org)
  • anion
  • Delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether a mixed acid base disorder (metabolic acidosis) is present. (wikipedia.org)
  • are oddities, mathematically speaking: Result 1: if there is a normal anion gap acidosis, the [ AG - 12 ] part of the equation will be close to zero, the delta ratio will be close to zero and there is no mixed acid-base disorder. (wikipedia.org)
  • Result 4: if the result of the ratio is greater than 2 in a high anion gap metabolic acidosis, it is usually because there was a pre-existing higher than normal bicarbonate level. (wikipedia.org)
  • radius ratio Radius of a cation divided by that of an anion . (encyclopedia.com)
  • Ions tend to pack closely together in a low-energy, stable state and the most stable arrangements are classified in terms of the cation-to-anion radius ratio. (encyclopedia.com)
  • Oxygen is the major anion in most minerals, so the radius ratio of various cations to oxygen is particularly important. (encyclopedia.com)
  • lengths
  • Vincenzo Galilei, father of Galileo, discovered that the ratio of an interval is proportional to string lengths, but varies as the square of the tension applied to the strings. (leeds.ac.uk)
  • nurse
  • The cooled treatment alcohol is occasional with dilute enough tag, ratio prednisolone 1 study, nurse and canada particularly with mg/m2 until valuable. (netibuy.com)
  • 36 bed cardiac interventional unit, 4 to 1 patient/nurse ratio, with 4 aides that split the unit. (allnurses.com)
  • Not a big fan of Florida anyway (no offense) and have no desire to work there, and seeing the nurse to patient ratio makes me realize another reason why I don't want to work there. (allnurses.com)
  • occasional
  • Our ICU has an ideal ratio of 2:1, with the occasional 3:1, and they also have their own monitor, MD, and do lots more with drip titration, etc, than any other unit. (allnurses.com)
  • means
  • If the proportional hazard assumption holds, a hazard ratio of one means equivalence in the hazard rate of the two groups, whereas a hazard ratio other than one indicates difference in hazard rates between groups. (wikipedia.org)
  • A contrast ratio of 2,500:1, for example, means that the display is capable of displaying whites that are 2,500 times as bright as the darkest black. (reference.com)
  • relative
  • Hazard ratios differ from relative risks and odds ratios in that RRs and ORs are cumulative over an entire study, using a defined endpoint, while HRs represent instantaneous risk over the study time period, or some subset thereof. (wikipedia.org)
  • A rate ratio (sometimes called an incidence density ratio) in epidemiology, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time. (wikipedia.org)
  • Delta
  • Since the anions are unable to diffuse out of the bloodstream, while bicarbonate and hydrogen ions diffuse with ease (as H₂CO₃, carbonic acid), the usual result will be closer to a delta ratio of 1 to 2. (wikipedia.org)
  • free
  • But factors with relevant chronic spreads, or a free partum of ratio drug prednisolone after insulin osteocytes, may be put on the information when they start their 20- service. (netibuy.com)
  • large
  • The existence of multiple theories seems unnecessarily complex to modern sensibility since ratios are, to a large extent, identified with quotients. (wikipedia.org)
  • already
  • Second, the lack of a widely used symbolism to replace the already established terminology of ratios delayed the full acceptance of fractions as alternative until the 16th century. (wikipedia.org)
  • study
  • In its simplest form, the hazard ratio can be interpreted as the chance of an event occurring in the treatment arm divided by the chance of the event occurring in the control arm, or vice versa, of a study. (wikipedia.org)
  • origin
  • It is impossible to trace the origin of the concept of ratio because the ideas from which it developed would have been familiar to preliterate cultures. (wikipedia.org)
  • However, it is possible to trace the origin of the word "ratio" to the Ancient Greek λόγος (logos). (wikipedia.org)
  • example
  • For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). (wikipedia.org)
  • relationship
  • The hazard ratio is simply the relationship between the instantaneous hazards in the two groups and represents, in a single number, the magnitude of distance between the Kaplan-Meier plots. (wikipedia.org)
  • amount
  • Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7). (wikipedia.org)
  • monitors
  • Contrast ratio is used for display devices, such as monitors or televisions, as a measurement between the darkest black displayable and the brightest white. (reference.com)
