Tin plate is now sold both on a weight per unit area basis and on a thickness basis. The old unit of area is the base box, equal to the area of 112 sheets, 14 by 20 inches, or 31 360 square inches(217. 78 square feet). The new unit of thickness is the millimetre and the corresponding area designation for pricing and weight or area calculations is the SITA(System International Tin Plate Area) which equals 100 square metres or 4. 9426 base boxes.... The use of symbols to designate gage was displaced by the use of base weights(or basis weights) expressed in pounds per base box that also indicated the approximate thickness of the tin-mill product...

Tinplate sheets used to manufacture cans and boxes were originally packed into wooden boxes in order to protect the polished tin surface. Sheets cut to 35 cm X 50 cm (14 X 20 in) and of 0.3 mm thickness weighed approx. 454 g (1 lb) and 112 were packed into a box, known as the "basis box". Variation in thickness of sheet cut to the same size would vary the weight, and larger sizes were made, although these were then called "tinned sheets". Modern production techniques favour reeling into rools for shipment, and protection with interleaving of paper or plastic where necessary.  3, record 2, English, - base%20box

... a soil/duff drought index [developed by Keetch and Byram (1968]) that ranges from 0 (no drought) to 800 (extreme drought) and is based on soil capacity of 8 inches of water. Factors in the index are maximum daily temperature, daily precipitation, antecedent precipitation, and annual precipitation.  4, record 3, English, - Keetch%2DByram%20drought%20index

The Keetch Byram Drought Index (KBDI) provides a daily measure of soil dryness, which, in turn, gives an indication of water stress in plants. The KBDI represents the net effect of precipitation and evapotranspiration in producing cumulative moisture deficiency in deep duff or upper soil layers. The KBDI has a range from 0 (no drought or soil moisture deficiency, i.e. soil at field capacity) to 2000 (extreme drought, maximum soil moisture deficiency possible). The index can be viewed as the amount of rain needed to bring the soil back to saturation, with one mm of rain reducing the index by 10 points. The 0-2000 point scale is divided into three drought classes: 0-999 = Low; 1000-1499 = Moderate; 1500 - 2000 = High. The KBDI is simple to calculate as it uses only two, daily weather observations - maximum temperature and 24-hour rainfall. The system functions in a book-keeping fashion where estimates of daily evapo-transpiration and measurements of precipitation increase or decrease the value of yesterdays index. The KBDI by itself is not a Fire Danger Rating System as it gives no indicate of the ease of ignition of the vegetation, or of the rate of fire spread, fire intensity and difficulty of control. It does however serve as a useful measure of drought occurrence.  7, record 3, English, - Keetch%2DByram%20drought%20index

Keetch-Byram Drought Index (KBDI): ... 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity. Typical of spring dormant season following winter precipitation. 200 - 400: Typical of late spring, early growing season. Lower litter and duff layers are drying and beginning to contribute to fire intensity. 400 - 600: Typical of late summer, early fall. Lower litter and duff layers actively contribute to fire intensity and will burn actively. 600 - 800: Often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.  9, record 3, English, - Keetch%2DByram%20drought%20index

Record number: 4, Textual support number: 2 CONT

The speed of light in a vacuum is an important physical constant denoted by the letter c for "constant" or the Latin word "celeritas" meaning "swiftness". It is the speed of all electromagnetic radiations, including visible light, in a vacuum. More generally, it is the speed of anything having zero rest mass.... In metric units, the speed of light is exactly 299, 792, 458 metres per second(1, 079, 252, 848. 8 km/h). The fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299, 792, 458 of a second; any increase in the precision of the measurement of the speed of light would refine the definition of the metre, but not alter the numerical value of c. The approximate value of 3x10⁸ m/s is commonly used in rough estimates. In imperial units, the speed of light is about 670, 616, 629. 2 miles per hour or 983, 571, 056 feet per second, which is about 186, 282, 397 miles per second, or roughly one foot per nanosecond. The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity is called the refractive index of the medium.  5, record 4, English, - speed%20of%20light
