  • substance
  • three of which H. W. B. Roozeboom had distinguished by the year 1899: Conglomerate (sometimes racemic conglomerate) If the 'molecules' of the substance have a much greater affinity for the same enantiomer than for the opposite one, a mechanical mixture of enantiomerically pure crystals will result. (wikipedia.org)
  • ammonium
  • One of the first such racemates studied, by Pasteur in 1853, forms from a 1:2 mixture of the bis ammonium salt of (+)-tartaric acid and the bis ammonium salt of (−)-malic acid in water. (wikipedia.org)
  • Re-investigated in 2008, the crystals formed are dumbbell-shape with the central part consisting of ammonium (+)-bitartrate, whereas the outer parts are a quasiracemic mixture of ammonium (+)-bitartrate and ammonium (−)-bimalate. (wikipedia.org)
  • amounts
  • In chemistry, a racemic mixture, or racemate /reɪˈsimeɪt/, is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. (wikipedia.org)
  • racemic
  • The information on this card is for the racemic mixture. (inchem.org)
  • In chemistry, a racemic mixture, or racemate /reɪˈsimeɪt/, is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule. (wikipedia.org)
  • The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. (wikipedia.org)
  • A racemic mixture is denoted by the prefix (±)- or dl- (for sugars the prefix dl- may be used), indicating an equal (1:1) mixture of dextro and levo isomers. (wikipedia.org)

  • The reagents of, and the reactions that produce, racemic mixtures are said to be "not stereospecific" or "not stereoselective", for their indecision in a particular stereoisomerism. (wikipedia.org)
  • Dolly Mixture
  • Dolly Mixture! (behance.net)
  • Dolly Mixture is a British confection, consisting of a variety of multi-coloured fondant shapes, such as cubes and cylinders, with subtle flavourings. (wikipedia.org)
  • Over time the name Dhal Mixture is thought to have led to the name Dolly Mixture. (wikipedia.org)
  • The Goon Show character Bluebottle was frequently rewarded, or able to be bribed, with a quantity of dolly mixture, jelly babies, or similar sweets. (wikipedia.org)
  • Dolly Mixture were an English band formed in 1978 by bassist and vocalist Debsey Wykes (born 21 December 1960, Hammersmith, London, England), guitarist and vocalist Rachel Bor (born 16 May 1963, Wales), and drummer Hester Smith (born 28 October 1960, East Africa). (wikipedia.org)
  • Dolly Mixture supported The Undertones on one of their first UK tours. (wikipedia.org)
  • After Sensible had a hit with "Happy Talk" in 1982 (featuring Dolly Mixture, credited as "Dolly Mixtures" on the single, and also in the song's video) and following various appearances on the television show Top of the Pops, Dolly Mixture - as a separate entity from Captain Sensible - performed extensively. (wikipedia.org)
  • It was produced by Dolly Mixture and Andrew Fryer. (wikipedia.org)
  • In 2010, Dolly Mixture release a three CD box set including the Demonstration Tapes album, all of the band's singles plus a complete disc of additional demos and live recordings, many of which are available for the first time. (wikipedia.org)
  • Soda
  • Similar to the Bordeaux mixture, one of the earliest fungicides in use, Burgundy mixture, also known as "sal soda Bordeaux", is used as a fungus preventative applicant on plants before fungi have appeared. (wikipedia.org)
  • ions
  • Bordeaux mixture achieves its effect by means of the copper ions (Cu2+) of the mixture. (wikipedia.org)
  • Unfortunately, the mechanism for copper antifungal properties is not well understood, though it is thought that interactions between the copper and negatively charged portions of the cellular membranes of the fungi promote an altered shape and increased membrane permeability, which alters the homeostasis of the cell and can lead to insufficient uptake and storage of essential nutrients and ions.Use Bordeaux mixture than this it is effective. (wikipedia.org)
  • temperature
  • A frigorific mixture is a mixture of two or more phases in a chemical system that, so long as none of the phases is consumed during equilibration, reaches an equilibrium temperature that is independent of the starting temperature of the phases before they are mixed. (wikipedia.org)
  • When ammonium chloride salt is placed on ice when the ambient temperature is greater than −17.8 °C (0 °F), the salt melts some of the ice and the temperature drops to −17.8 °C. Since the mixture is colder than the ambient temperature , heat is absorbed and the temperature rises. (wikipedia.org)
  • This results in little to no net cooling capacity at the desired temperatures and an end mixture temperature that is higher than it was to begin with. (wikipedia.org)
  • Temperature variation and heat transfer phenomena in the intake port of a spark ignition engine with port injection play a significant role in the mixture preparation process, especially during the warm up period. (sae.org)
  • The droplet, liquid film and gas-phase mixture temperature variations and the effects of charge air, initial fuel and port wall temperatures involved in generating the air-fuel mixture are examined. (sae.org)
  • powders
  • Cookbooks of the 19th century began to record curry powders (from recipes sent home by colonial administrators) and mixtures that were often called kitchen pepper. (msn.com)
  • If two different powders are mixed perfectly, three theoretical powder mixtures can be obtained: the random mixture, the ordered mixture or the interactive mixture. (wikipedia.org)
  • Liquid
  • When a liquid mixture is heated, the liquid with the lower boiling point evaporates (becomes a vapor), leaving behind the liquid with the higher boiling point. (factmonster.com)
  • model
  • In this work, a one-dimensional, unsteady, multicomponent, multiphase flow model has been developed to study the mixture formation process in the intake port for a modern, multipoint-fuel-injection, gasoline engine. (sae.org)
  • The model not only quantitatively identifies the effects of each parameter on the final mixture but also shows the interactive influences of three phases of the mixture during the process. (sae.org)
  • weights
  • Some ways of implementing mixture models involve steps that attribute postulated sub-population-identities to individual observations (or weights towards such sub-populations), in which case these can be regarded as types of unsupervised learning or clustering procedures. (wikipedia.org)

  • Ham's Nutrient Mixtures were originally developed to support growth of several clones of Chinese hamster ovary (CHO) cells, as well as clones of HeLa and mouse L-cells. (sigmaaldrich.com)
  • The Penning mixture used in plasma displays is usually helium or neon with small percentage of xenon, at several hundred torr. (wikipedia.org)
  • often
  • Mixtures relying on the use of acid base slushes are of limited practical value beyond producing melting point references as the enthalpy of dissolution for the melting point depressant is often significantly greater (e.g. (wikipedia.org)
  • Dal or dahl is an Indian mixture of beans, peas, or legumes which are often made up of different sizes and colours. (wikipedia.org)
