The light absorption coefficient of water is dependent on temperature and concentration of ions, i.e. the salinity in seawater. Accurate knowledge of the water absorption coefficient, a, and/or its temperature and salinity correction coefficients, Ψ(T) and Ψ(S), respectively, is essential for a wide range of optical applications. Values are available from published data only at specific narrow ...

This article reveals the leading role of standards in Industrial Ecology. It describes the tendency for the modern stage of world development to introduce widely accepted international standards. Along with this, each country has it own system of standards and respective specifics. A number of significant standards are available for practical operations of industries and institutions, e.g. the ...

Enamel anomalies – amelogenesis imperfecta, 1: 14000, several types with different heredity. Most frequent type is AD with hypomineralisation. Enamel matrix is normaly created, but the mineralisation is insufficient. The enamel is soft,peels off. Teeth are yellowbrown. Open bite is common. Reduction of pulp chamber occurs relatively early, so the reconstruction with crowns could be provided bef...

We establish a …rst order asymptotic for the entropy integrals Z I pn log pn W 2 and Z I pn log (pnW ) 2 W 2 where fpngn=0 are the orthonormal polynomials associated with the exponential weight W . 1 The Result Let I = (c; d) be a real interval, where 1 c < 0 < d 1; and let Q : I ! [0;1) be convex. Let W := exp ( Q) and assume that all power moments Z I xW (x)dx; n = 0; 1; 2; 3; ::: are …nite. ...

It is important to consider discomfort glare in designing comfortable office environment. Architectural Institute of Japan has set UGR and PGSV as design criteria for glare, but those indicators do not completely reflect the needs lighting environments due differences work behavior. For example, when performing a task that requires concentration, worker may prefer environment increase one's lev...
