So, grazing sheep on a cool-season grass pasture is a balancing act between the first flush of spring growth, grass going to seed later in the spring, and the hot weather dormancy.... Put the sheep into a field when the grass is about 6-8 inches high, and move them to the next field when they’ve grazed the first to about 3-4 inches. Keep moving them, but also watch your other paddocks. In the spring, it's easy for the growth to get ahead of your sheep. You may need to mow a paddock or two to make sure they don’t go to seed before they are grazed. 3, record 3, English, - grass%20pasture

An elementary and unschooled way of propelling oneself in the water : imperfect prone position, head out of the water facing straight ahead, arms alternately and nervously moving forward and backward under the water, away from the body and without a complete extension forward nor a full traction and pull along the body backward, legs beating in a bending-and-unbending motion of the knees rather than in an effective beat of the extended legs on the surface of the water. 2, record 8, English, - dog%20paddle
Record number: 8, Textual support number: 1 OBS
The unschooled way a human propels himself through the water. Children’s paddling is often more chaotic, with the arms alternately clawing at the water to move forward; breathing is irregular, legs thrashing and inconsistent. A more mature dog paddle can be rhythmic and steady, but the arms never go out of the water and the head is never submerged. Thus the stroke closely resembles a dog moving through the water. 3, record 8, English, - dog%20paddle

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead]. 2, record 13, English, - laser%20velocimeter

Le principe de fonctionnement du vélocimètre à laser (ou lidar) est exactement le même que celui des radars météorologiques Doppler de bord, qui doivent être mis en service prochainement pour la détection des turbulences dans les systèmes d'orages. 1, record 13, French, - v%C3%A9locim%C3%A8tre%20%C3%A0%20laser
