If the respiratory rate is low (for example 10 breaths per min, corresponding to a frequency of 0.17 Hz, very near to the upper limit of LF), some amount of HF band overlaps with the LF band, thus the exact estimation of both bands becomes difficult.
The estimation of energy band gap in nanostructural semiconductors is somewhat difficult because surface atoms edges of the valence and conduction bands are not abrupt and the tail states complicate the definition of the true optical gap [1, 2, 3, 4, 5, 6, 7, 8].
Lines represent the estimation of SPPC band gap using the Bragg conditions.
To characterize the physical properties of thin films without ambiguity and design interface with new functionalities, it is essential to have detailed knowledge of physical properties and appropriate estimation of the band profile of perovskite oxide substrates.
The most used method for the estimation of the band gap from optical measurement is the one proposed by Tauce [13].
However, if one is interested in estimation of the band gap, the precise choice of constants is less critical, as the difference in the calculated diameter from the actual value is small.
In-gel iron estimation of protein bands and the iron content of liver and spleen homogenates were performed by Ferene-S staining essentially as described [14].
