The killing of a considerable number of human beings under circumstances of atrocity or cruelty, or contrary to the usages of civilized people; as, the massacre on St. Bartholomew's Day. 2. Murder. Synonym: Massacre, Butchery, Carnage. Massacre denotes the promiscuous slaughter of many who can not make resistance, or much resistance. Butchery refers to cold-blooded cruelty in the killing of men as if they were brute beasts. Carnage points to slaughter as producing the heaped-up bodies of the slain. "I'll find a day to massacre them all, And raze their faction and their family." (Shak) "If thou delight to view thy heinous deeds, Brhold this pattern of thy butcheries." (Shak) "Such a scent I draw Of carnage, prey innumerable !" (Milton) Origin: F, fr. LL. Mazacrium; cf. Prov. G. Metzgern, metzgen, to kill cattle, G. Metzger a butcher, and LG. Matsken to cut, hew, OHG. Meizan to cut, Goth. Maitan. Source: Websters Dictionary (01 Mar 1998) |

| spectrometry, mass, fast atom bombardment | A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information. (12 Dec 1998) |
| spectrometry, mass, matrix-assisted laser desorption-ionization | A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis. (12 Dec 1998) |
| spectrometry, mass, secondary ion | A mass-spectrometric technique that is used for microscopic chemical analysis. A beam of primary ions with an energy of 5-20 kiloelectronvolts (kev) bombards a small spot on the surface of the sample under ultra-high vacuum conditions. Positive and negative secondary ions sputtered from the surface are analyzed in a mass spectrometer in regards to their mass-to-charge ratio. (12 Dec 1998) |
| spectrum analysis, mass | Analysis of the mass of an object through means of determining the wave length(s) at which electromagnetic energy is absorbed by that object. (12 Dec 1998) |
| injection mass | Coloured solutions or suspensions injected into the vascular system to render vessels and their walls prominent; useful for gross preparations and for study under low magnification after clearing; most fluids contain warm gelatin and the colouring materials are carmine, Berlin blue, or carbon. (05 Mar 2000) |
| inner cell mass | A group of cells found in the mammalian blastocyst that give rise to the embryo and are potentially capable of forming all tissues, embryonic and extra embryonic, except the trophoblast. (18 Nov 1997) |
