Refimprove date October 2010 The Baum scale is a pair of hydrometer scales developed by French pharmacist Antoine Baum in 1768 to measure density of various liquids. The unit of the Baum scale has been notated variously as degrees Baum , B , B and simply Baum the accent is not always present . One scale measures the density of liquids heavier than water and the other, liquids lighter than water. The Baum of distilled water would be 0. Conversions At convert 20 C , the relationship between specific gravity s.g. relative density and degrees Baum is For liquids more dense than water s.g. 145 145 degrees Baum For liquids less dense than water s.g. 140 degrees Baum 130 . An older version of the scale for liquids heavier than water, at a reference temperature of convert 15.5 C , uses 144.32 rather than 145. Definitions Baum degrees heavy originally represented the percent by mass of sodium chloride in water at convert 60 F . Baum degrees light was calibrated with 0 B light being the density of 10 NaCl in water by mass and 10 B light set to the density of water. Other scales Because of vague instructions or errors in translation a large margin of error was introduced when the scale was adopted. The API gravity scale is a result of adapting to the subsequent errors from the Baum scale. The Baum scale is related to the Balling, Brix , Plato scale Plato and Gravity beer specific gravity times 1000 scales. Use Before standardisation on specific gravity around the time of World War II the Baum scale was generally used in industrial chemistry and pharmacology for the measurement of density of liquids. Today the Baum scale is still used in various industries such as brewing, sugar beet Processing sugar beet processing , ophthalmics, starch industry, and winemaking.

orphan date March 2010 The Bovis scale , named after French Radiesthesia radiesthesist Andr Bovis 1871 1947 also referred to as either Antoine or Alfred by some authors , is a concept used by Dowsing dowsers and adherents of geomancy to quantify the strength of a postulated cosmo telluric energy inherent in a location. The attribution to Bovis is due to his grandson, the self designated geobiologist Jacques Bovis. The concept was further developed by one Andr Simoneton 1949 , who introduced the term radio vitality radiovitalit . Simoneton s scale was in turn developed into a modern Bovis scale by Swiss geobiologist and former Vaud cantonal parliament member Blanche Merz 1919 2002 , who founded an Institut de recherches en g obiologie at Chardonne in 1979 and whose self published books appeared from the 1980s. Merz books enjoyed some popularity in French speaking Switzerland and were reprinted by commercial publishers in the later 1980s and 1990s, in translation also reaching German speaking Europe . Merz 1983 Hauts Lieux Cosmo T lluriques in 1987 was also published in English translation. The unit of the Bovis scale is the Angstrom 1 0,1 nm or 10 sup 10 sup m . The measurement consists of the operator placing a detecting device on or near the Bovis scale diagram and noting the Bovis number. A number of 6,500 fresh, raw, vegetable foods is considered sufficient to keep the energetic balance , lower figures negatively affect human life and body functioning, higher numbers as detected in fresh, ripe fruit and freshly pressed juices, seeds and sprouts, which score 8,000 10,000 on the Bovis scale have positive effects aiding physiological functions.

unsourced date February 2011 temperature The Delisle scale D is a temperature scale invented in 1732 by the French astronomer Joseph Nicolas Delisle 1688&ndash 1768 . Delisle was the author of M moires pour servir l histoire et aux progr s de l Astronomie, de la G ographie et de la Physique 1738 . He had been invited to Russia by Peter I of Russia Peter the Great . In 1732 he built a thermometer that used mercury element mercury as a working fluid. Delisle chose his scale using the temperature of boiling water as the fixed zero point and measured the contraction of the mercury with lower temperatures in hundred thousandths. The Celsius scale, likewise, originally ran from zero for boiling water down to 100 for freezing water. This was reversed to its modern order some time after his death, in part at the instigation of Daniel Ekstr m , the manufacturer of most of the thermometers used by Celsius. The Delisle thermometers usually had 2400 graduations, appropriate to the winter in Saint Petersburg St. Petersburg . In 1738 Josias Weitbrecht nowrap 1702&ndash 47 recalibrated the Delisle thermometer with 0 degrees as the boiling point and 150 degrees as the freezing point of water. The Delisle thermometer remained in use for almost 100 years in Russia.

The Oechsle Scale is a hydrometer scale measuring the density of grape must , ref By a slight abuse of physical terminology one says in German that the Mostgewicht must weight is measured rather than the must s density. ref which is an indication of grape ripeness and sugar content used in wine making . It is named for Ferdinand Oechsle 1774 1852 and it is widely used in the German wine German , Switzerland Swiss and Luxembourg ish wine making industries. On the Oechsle scale, one degree Oechsle Oe corresponds to one gram of the difference between the mass of one litre of must at 20 Celsius C and 1 kg the mass of 1 litre of water . For example, must with a density specific mass of 1084 grams per litre has 84 Oe. Overview The mass difference between equivalent volumes of must and water is almost entirely due to the dissolved sugar in the must. Since the alcohol in wine is produced by Fermentation wine fermentation of the sugar, the Oechsle scale is used to predict the maximal possible alcohol content of the finished wine.

Scale relativity is a theory of space time initially developed by Laurent Nottale , working at the French observatory of Meudon, near Paris. It is an extension of the concept of Theory of relativity relativity found the special relativity and general relativity to physical scale spatial scale s time, length, energy, or momentum scales . If scales in nature are always relative, an absolute scale cannot exist. As a consequence, fundamental physical laws need to be scale invariant . While differential trajectories found in standard physics are automatically scale invariant, it is the main insight of the theory that also certain non differential trajectories which explicitly depend on the scale of the observer can be scale invariant and new tools are developed to treat such trajectories.

It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1 152. It is, therefore, similar in size to the slightly larger British N scale at 1 148 and the slightly smaller European American N scale at 1 160 it predates both versions of N scale. The track rail gauge gauge used is RailGauge 9.42mm , wider than commercial N scale. Track and wheels are closer to scale replicas than commercial N the track is only 1 mm high. No ready to run models are available in this scale, and although there is some availability of kits and components, some modelmaking skill is required. With such skill, however, excellent models can be produced in a very tiny size.
