Consequently, global meta-analyses of epidemiologic studies indicate that indoor air pollution from solid fuel use in China is responsible for approximately 420,000 premature deaths annually, more than the approximately 300,000 attributed to urban outdoor air pollution in the country.
Spectra for polycrystalline graphite usually show a narrow G peak (approximately 1,580 cm-1) atoributed to in-plane vibratiofs of crystalline graphite, and a smaller D peak (approximately 1,360 cm-1) atoributedisordereddered amorphous carbon [11].
The band at approximately 1,315 can1 can be assigned to the C-N mode [20], while the band at approximately 1,146 cm−1 is the characteristic band of the stretching vibration of quinoid, and the band appearing at approximately 820 cm−1 is attributed to an aromatic C-H out-of-plane bending vibration [19].
The loss in conductivity, as compared to the untethered salt complexes, corresponds approximately to that attributed to the anionic conductivity.
Featuring approximately twenty works attributed to Sittow, as well as paintings by his contemporaries, including Hans Memling and Juan de Flandes, this book provides an important opportunity to learn about Sittow's oeuvre and to appreciate it within the cultural context of his homeland as well as the broader milieu of early northern Renaissance art.
The peaks at approximately 400°C was attributed to NH3 desorption from the strong Brönsted acid sites [9, 10, 17, 18].
As shown in Figure 3, Al-MCM-48 has weak acidity because the peak at approximately 220°C was attributed to NH3 desorption from the weak acid.
The first weight loss, at approximately 144 °C, is attributed to the removal of loosely bound water molecules from the LDHs interlayer.
For the specific example, the runtime overhead increases 110 times approximately a phenomenon attributed to the high number of redundant re-optimizations that are performed.
The D peak is located at approximately 1,350 cm−1, attributed to the breathing mode of sp2 atoms, and originated by the existence of some defects such as edges, grain boundaries, functional groups, or structural disorders [23].
