EVALUATION OF POROUS MATERIALS BY MEASURING THE COEFFICIENT OF REDUCTION SCATTERING ^{[№ 9 ' 2012]}
We propose to evaluate the porosity of bulk samples of materials to the value of the reduced scattering coefficient. Submitted by X-ray diagram of the measurement method and the block diagram of the experimental equipment. It is shown that the reduced scattering coefficient depends linearly on the porosity.

GERONTOLOGICAL THEORIES OF PEOPLE ACTIVITY IN MIDDLE AGE ^{[№ 4 ' 2003]}
Old age is peculiar age-psychological period, which attracts great changes. Traditionally old age is interpreted as process of degradation and decline, however development of a man takes place in this period too. Twenty-thirty age, which a man lives in old age, is enough term for acquisition of new knowledge and skills. In many cases, life activation is necessary condition for life quality improvement.
