altitude [al′tito̅o̅d] Etymology: L, altitudo, height the level of elevation of any location on earth with reference to a fixed surface point, which is usually sea level. Several types of health effects are associated with altitude extremes, including a greater intensity of ultraviolet radiation that results from a thinner atmosphere. Barometric pressure decreases as altitude increases, so there are fewer molecules of oxygen. Thus breathing becomes faster & deeper, although demands of physical effort and cellular respiration are the same as at a lower altitude. High-altitude cardiac intolerance is usually worse in people with blood or pulmonary disorders. See also altitude sickness. altitude, n pertaining to any location on earth with reference to a fixed surface point, which is usually sea level. The higher the altitude, the lower the oxygen concentration and the greater the ultraviolet radiation, both of which can cause health problems. How to thank TFD for its existence?

The Institute plans featured research
work concerning the designing and improvement of the Earth surface
aerial photography methods, the analytically supported vast-scale
topographical plotting, the methods of third- and fourth-order levelling
and the elaboration of altitudinal theodolite traverses, the working out
of guidelines and manuals for conducting various geodetic and
topographical work. Negative altitudinal patterns of
professionals toward individuals with psychiatric disabilities serve to
undermine the therapeutic relationship (Thorne, Nyhlin, & Paterson,
2000) and such tendencies on the part of professionals' serves to
further diminish the rehabilitation and recovery of the person with a
psychiatric disability (Singer, 2001). However,
all were given fields for subsistence production, even where the
settlements were near the altitudinal limits of agriculture and had to
be supplemented with food production from lowland colonies. |
