CANDELA a unit of luminous intensity, defined as 1/60 of the luminous intensity per square centimeter of a black-body radiator operating at the temperature of freezing platinum (1772 °C), Formerly known as a candle. The unit is abbreviated as Cd... [Pg.419]

Some specific metrics for mass have been found to be useful and are described elsewhere. In addition to reaction mass efficiency described elsewhere and in Chapter 4, a useful metrics is Mass Intensity, defined as ... [Pg.231]

The basis for the measurement of the strength of light absorption by a molecule at various wavelengths is shown in Fig. 3.11. A parallel monochromatic light beam of wavelength A and power P ] or intensity / , defined as the energy per second striking a unit area,... [Pg.53]

Therefore the scattering intensity defined in equation (5.20) is directly proportional to the osmotic compressibility ... [Pg.139]

Calibrator beads with known fluorescence intensity defined in terms of equivalent molecules of soluble fluorochrome (e.g., Quantum Beads, Flow Cytometry Standards Corporation). [Pg.325]

Gating obviously can be used to fine-tune between selectivity and sensitivity On increasing the gating time from 0 to 100 ps, the normalized intensity [defined as (F-Fo)/Fo] of all species is increased (Fig. 16b) except for KG. On increasing the gating time to 250 ps, oxaloacetate is widely suppressed and citrate is reduced by 40%, while isocitrate, fumarate, and malate remain much less affected. Obviously, L-malate and oxaloacetate, and citrate and isocitrate can be nicely discerned via different delay times. [Pg.69]

The value of the exchange modes of the magnetic resonance has the same order of a magnitude as triplet excitations in the dimerized state [5], These modes exist in both U- and D-AFM states. Furthermore, these modes excite by a high frequency magnetic field polarized perpendicular to easy axis. Their intensities define by the DM interactions. The spin oscillations in these modes respect to a violation of 3D AFM order along chains as well as between chains. Therefore, one can expect an amplification of their intensities under motion of boundaries between coexisting SP- and AFM states. The next experiments are necessary to make situation clear. [Pg.236]

The candela (cd) is the SI unit of luminous intensity, defined as follows In a given direction, 1 candela of a source emits monochromatic radiation of frequency v = 540 x 1012 hertz and has a radiant intensity in that direction of... [Pg.586]

As mentioned above, calculated absorbance values derived from peak height measurements are sensitive to matrix effects as well as changes in instrument properties. The integrated intensity defined as... [Pg.419]

Although the concept of radiance is the same as the intensity defined in Equation (7.3), it is commonly used in radiation thermometry. Therefore, both the term radiance and its symbol L are retained here. [Pg.587]

Developing the photographic plates, Becquerel observed an intensely defined silhouette on the first two plates, and a clear but considerably weaker silhouette on the third. Because he had double-boxed his plates inside his dark room and had placed the ensembles inside a drawer that he then closed, he was able to conclude that his mysterious rays were not related to phosphorescence and were not induced by stmfight. [Pg.139]

Drag coefficients may be affected by turbulence in the free-stream flow the drag crisis occurs at lower Reynolds numbers when the free stream is turbulent. Torobin and Guvin (AlChE J., 7,615-619 [1961]) found that the drag crisis Reynolds number decreases with increasing free-stream turbulence, reaching vdue of 400 when the relative turbulence intensity, defined as is 0.4. Here Vu is the rms... [Pg.681]

In pRISM theory, the MIST process is directly reflected in the normalized static structure factor, S(copolymer system is cooled and microdomains are forming, the peak scattering intensity grows in a mean-field maimer corresponding to the linear portion of the S(< ) curve in the coordinates Extrapolation of this linear portion to divergent intensity defines an apparent mean-field spinodal temperature. ... [Pg.712]

There is an issue yet to be resolved for the energy intensity defined in equation (2.3). The energy use ( ) for a process consists of fuel, steam, and electricity. They are not additive because they are different in energy forms and quality. However, if these energy forms can be traced back to fuel fired at the source of generation, which is the... [Pg.11]

Candela kan- de-b, - de-, - da- kan-do-b [L, candle] (1949) (cd) n. One of the six basic units of the SI system, the unit of luminous intensity, defined as the luminous intensity normal to the surface of 1/60 of a square centimeter of a black body at the temperature of freezing platinum (1772°C) under a pressure of 101.325 kPa. In older literature, the same abbreviation has been used for both candlepower and candle, which have different values. [Pg.151]
