61thermodynamics — thermodynamicist, n. /therr moh duy nam iks/, n. (used with a sing. v.) the science concerned with the relations between heat and mechanical energy or work, and the conversion of one into the other: modern thermodynamics deals with the properties …
62roads and highways — ▪ transportation Introduction traveled way on which people, animals, or wheeled vehicles move. In modern usage the term road describes a rural, lesser traveled way, while the word street denotes an urban roadway. Highway refers to a major… …
63Chemical thermodynamics — is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. Chemical thermodynamics involves not only laboratory measurements of various… …
64Montreal Protocol — For other similarly named agreements, see Montreal Convention (disambiguation). The largest Antarctic ozone hole recorded as of September 2006 The Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention… …

66Radial velocity — is the velocity of an object in the direction of the line of sight (i.e. its speed straight towards you, or away from you). The light of an object with a substantial radial velocity will be subject to Doppler effect, so the frequency of the light …
67Diffuse interstellar band — Relative strengths of observed diffuse interstellar bands Diffuse interstellar bands (DIBs) are absorption features seen in the spectra of astronomical objects in our galaxy. They are caused by the absorption of light by the interstellar medium.… …
68Retroflex trill — The retroflex trill has been reported from the Dravidian language Toda, and confirmed with laboratory measurements. Peter Ladefoged transcribes it with the IPA symbol normally associated with the retroflex flap, IPA|ɽ. Although the tongue starts… …
69Doubly articulated consonant — Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner (both plosive, or both nasal, etc.). They are a subset of co articulated consonants. They are to be distinguished from co… …
70Gravitational shielding — The term gravitational shielding refers to a hypothetical process of shielding an object from the influence of a gravitational field. Such processes, if they existed, would have the effect of reducing the weight of an object. All experimental… …
