The “raw material” for the measurements in question, may embrace rather wide circle of “mental elements,” including various kinds of knowledge and/or opinions (about everyday life, politics, science, art, literature, etc.), numerous feelings while perception, different creative abilities, and so forth (see, e.g., [3-6]).
In other words, the “raw material” may include all elements which relate to the sphere of “cultural wealth” of personality.

Abstract: 1, 10-phenanthroline and triethylamine modified palygorskites were prepared by microwave irradiation, and characterized with FT-IR technique.
In principle, solid material with a microporous structure such as zeolites, molecular sieves, clays, iron oxides and coal char can be used as an adsorbent.
Experimental 2.1 Materials and measurement Analytical grade of triethylamine, 1, 10-phenanthroline, hydrochloric acid, sodium hydroxide and manganese sulfate were were purchased from Shanghai Chemical Reagent Co.

Abstract.
Obviously, the material capability of the turbine blades limits this temperature.
Therefore improvements in creep strength through material development as well as single-crystalline casting and application of thermal barrier coatings increase the turbine efficiency [3].

Abstract.
Though a series of modified Z-A model were developed, such as Samantaray’s [11] model, the underlying physical process and the composition of the material components are not considered.
The various obstacles in the material have a contribution to the dislocation mean free path of slip, thus, the dislocation mean free path which combined the distance between the second-phase particles, the distance between the grain size and the distance to other dislocation is given by Engberg [18]
