English

Subject field(s)
  • Symptoms (Medicine)
  • The Lungs
CONT

A pulmonary shunt refers to the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of the lungs are perfused with blood as normal, but ventilation(the supply of air) fails to supply the perfused region. In other words, the ventilation/perfusion ratio(the ratio of air reaching the alveoli to blood perfusing them) is zero.

The train was equipped with a train information and braking system(TIBS) consisting of a sense and brake unit(SBU) mounted on the last car of the equipment left standing on the main track and an input and display unit(IDU) in the locomotive cab. The IDU displays the pressure in the brake pipe, emits an audible alarm when pressure drops below 48 pounds per square inch, and warns of zero brake pipe pressure. Also, movement of standing cars causes the display on the IDU to indicate the direction of movement of the car on which the IDU is mounted.... The TIBS is equipped with an emergency braking feature that can be used to remotely trigger an emergency brake application.

... a system of mutually perpendicular reference axes fixed in an aircraft ... and moving with it.

CONT

A good understanding of the basic axis system used to describe aircraft motion is necessary to fully appreciate flight test data, since all measurements are referenced to this axis system. Aircraft translational motion is described in terms of motion in three different directions, each direction being perpendicular to the other two(orthogonal). Motion in the X direction is forward and aft velocity. The Y direction produces sideways motion to the left and right, and up and down motion is in the Z direction... There are several slightly different versions of the basic axis system just described. They differ primarily in the exact placement of the zero reference lines, but are generally similar in their directions.(For example, the body-axis system uses the fuselage center line as the x axis, while a wind-axis system uses the direction that the aircraft is moving through the air as the x axis.)

The heavy black line on the artificial horizon represents the horizon line. If the airplane is above the horizon, it is climbing. If it is below the horizon, it is diving. The greater amount of climb or dive, the farther up or down the horizon line is seen. The artificial horizon dial also has a black arrowhead showing the degree of bank to left or right. If the airplane is banked to the right, the arrowhead points to the left of zero.

OBS

bank: The lateral inward inclination of an airplane when it rounds a curve.

L'horizon artificiel [...] sert à indiquer la position d'un avion par rapport à l'horizon terrestre symbolisé par une ligne séparant deux zones de couleurs différentes, l'une indiquant le ciel, l'autre la terre. L'attitude de l'avion est déduite de la position de cette ligne qui fournit des précisions sur le roulis et le tangage. Des marques sur les côtés précisent le degré d'inclinaison de l'avion et une bille située dans la partie inférieure informe le pilote du niveau de vol en dérapage.

Subject field(s)
  • Chemical Elements and Compounds
CONT

In reference to monohydric alcohols, amines, and a few related compounds, this term [primary], together with secondary and tertiary, describes the molecular structure of isomeric or chemically similar individuals. Monohydric alcohols are based on the methanol group,-C-OH, in which three of the bonds [up, down and left side] of the methanol carbon may be attached either to hydrogen atoms or to alkyl groups.... A secondary alcohol has two alkyl groups and one hydrogen.... The three types can be readily identified by the number of hydrogen atoms attached to the central(methanol) carbon atom : if it is 2 or more, the alcohol is primary; if 1, it is secondary; and if zero, it is tertiary. For example, CH3CH2OH; is primary;(CH3) CHOH; is secondary;(CH3) 3COH is tertiary.

Subject field(s)
  • Statistical Graphs and Diagrams
CONT

Basically, charts are drawn according to the system of rectangular co-ordinates. Rectangular co-ordinates are based on two straight reference lines perpendicular to each other in a plane(...) The horizontal line is usually referred to as the X-axis, or the abscissa, whereas the vertical line is referred to as the Y-axis, or the ordinate. The two lines divide the plane into four parts called quadrants(...) The point of intersection of the two lines is called the origin, or zero point. Scales are labeled along the two axes, beginning at the point of origin. The abscissas(...) to the right of the origin are conventionally designated as positive, whereas those to the left of the origin are negative. The ordinates(...) above the origin are positive, and those below the origin are negative. Any point on the plane may refer to two values according to the two scales.

CONT

La base de la représentation [graphique] est un système de coordonnées par rapport auquel on situe les points et les lignes. Le plus employé est le système de coordonnées rectangulaires ou (...) cartésiennes. Les points sont repérés par rapport à deux axes, l'un horizontal, dit des abscisses, l'autre vertical, dit des ordonnées. Le point 0 où ils se coupent est l'origine à partir de laquelle on compte les grandeurs positivement vers le haut et vers la droite, négativement vers le bas et vers la gauche.
