Determination of Greenhouse Gas Concentrations from the 16U CubeSat Spacecraft Using Fourier Transform Infrared Spectroscopy.

Greenhouse gases absorb the Earth's thermal radiation and partially return it to the Earth's surface. When accumulated in the atmosphere, greenhouse gases lead to an increase in the average global air temperature and, as a result, climate change. In this paper, an approach to measuring CO2 and CH4 concentrations using Fourier transform infrared spectroscopy (FTIR) is proposed.

[The index assessment of periodontal status in the combined treatment of patients with generalized periodontitis].

The authors compare the periodontal status in 94 patients with moderate periodontitis over the course of treatment making use of various splint designs and without splints. The status of the periodontium was assessed basing on the time course of indexes. Administration of various multiple-modality treatment schemes resulted in improvement of the periodontal clinical status in all the patients, though the efficacy of the therapeutic measures was different.
