Balagula Roman Bobylev Alexander Svensson Stefan Carrier lifetime in InAs / GaSb superlattice structures The time-resolved photoluminescence (PL) data are studied for strained-layer InAs / GaSb superlattice structures at different excitation powers. Photoluminescence and absorption spectra are obtained. The minority carrier lifetime is obtained from PL frequency response to sin-wave modulated excitation. Similar results follow from analysis of the time-resolved PL data. It has been concluded that the minority carrier lifetime is limited by Shockley-Read-Hall recombination. 535.3 SUPERLATTICE OPTICAL ABSORPTION CARRIER LIFETIME INFRARED LIGHT https://physmath.spbstu.ru/article/2013.19.2/ 02.pdf

In this work we show that the non-specific aggregation of the protein can be effectively countered by 0.05–0.10 % concentrations of a detergent Triton-X100. We also show that addition of the detergent destroys aggregates formed already that allows us to isolate oligomeric forms of the protein which may have biological significance. When combined, the results of small angle X-ray scattering and dynamic light scattering experiments suggest that TIP49A aggregation observed in vitro is reversible with the protein oligomerization in two different types of stable filamentous structures. 577.3 TIP49 proteins small angle X-Ray scattering light scattering https://physmath.spbstu.ru/article/2013.19.21/ 21.pdf

The functional relationship between the plumb-in line deviation and the Moon’s perigee position has been established for an arbitrary point on the rotating the Earth surface. This relationship manifests itself as variations in the gravitational acceleration vector direction and magnitude at the observation point or, in other words, as periodical deviations of the plumb-in line (local vertical).
