Equally the unions are concerned about the impact of increasing levels of contributions and the reduced likelihood of their members being able to meet the high physical demands of the job up to age 60.
The experimental group, compared to the control group who did not receive any feedback, showed an increased amount of contributions.
This increase may be related to an increase of baroreflex contribution to the respiratory oscillations in HPV[3].
In addition, we also observe that the increase of the contribution of the dust mass growth (dot-dashed line) has a peak, after which, the increase slows down.
It shows a common feature of all samples observed for every applied hydrogenation, i.e. an increase of the contribution of the vibration at higher wavenumber (approximately 2,100 cm−1) to the stretching mode with increasing annealing time.
Nevertheless, the interpretation of experimental FTIR spectra can be based on the comparison of infrared spectra of ZrO2 [30] and GeO2 and their transformation with the increase of the contribution of high-k phase in solid solution.
Indeed, the intensity of this band decreases at T c ≥ 800 °C (Fig. 2) that correlates with the appearance and increase of the contribution of monoclinic phase (Fig. 1) containing less oxygen vacancies than Y- or Cu-stabilized tetragonal phase [36].
This dilution leads to a decrease of silane deposition rate and to a marked increase of the contribution to deposition of unsaturated species such as silylene SiH2.
