In the absence of such a criterion the speed of light cannot be, as Lorentz supposed, empirically measured against the background of an inertial frame; in that case the only empirically sound definition of an inertial frame is the one that appeals to the speed of light.
Effusions were classified as benign (i.e., nonmalignant) on the basis of cytological and immunohistochemical features, and further classified as exudates or transudates on the basis of Light's criteria (Light et al, 1972).
Two of the often used, and sometimes misused, Bradford Hill "criteria," consistency and temporality, are critically reviewed in light of multicausality, thereby illustrating the need to review all of the criteria in light of 40 years of progress in science and policymaking.
Figure 3 summarises the criteria for light microscopic evaluation, cell counting and reporting of results.
The usefulness of biochemical criteria to separate pleural transudates from exudates is controversial, and the limitations of Light's criteria in patients receiving diuretic therapy is of general concern.
In all included studies, most studies took into account the limitations of Light's criteria and therefore diagnosed exudative pleural effusion by combining Light's criteria with clinical information, treatment response, and other data, which is widely considered an acceptable basis for exudate diagnosis.
A set of realistic design criteria for lighting power density, occupation density, and appliances' load-intensity for various types of premises have been established based on data obtained in walk-through surveys of energy end-uses in 31 Hong Kong office buildings.
This phenomenon is one of the limiting criteria in the design and operation of light water reactors.
Together, Wittgenstein's finitism and his criterion of algorithmic decidability shed considerable light on his highly controversial remarks about putatively meaningful conjectures such as FLT and GC.
The aim of this study is to define such objectives and criteria in the light of large sets of EQ-5D data collected from residents of the UK and four other European countries, and to illustrate how they may be applied to identify more relevant and efficient sampling schemes.
