Salt stress has become a major problem in the tomato planting process, of which peroxidase (POD) activity is an important parameter reflecting antioxidant capacity plants. In order to explore dynamic changes catalase leaves under different concentrations NaCl stress, it necessary establish rapid detection technology for POD micro-areas leaves. this study, total 139 microscopic images were obtai...

In 1923, Arthur Holly Compton introduced what today is known as the wavelength. Even if scattering derivation by relativistic in sense that it takes into account momentum of photons traveling at speed light, original indirectly assumes electron stationary moment scattered electrons, but not after has been hit photons. Here, we extend this to derive for case when initially moving a velocity v.

Design methods in the reciprocal space allow one to obtain structures with desired properties. Quasicrystalline photonic structures, which ensure selective scattering of an electromagnetic wave incident on sample, have been designed. The maxima Fourier transform distribution permittivity are located along two arcs Ewald sphere, corresponds required wavelength and angle incidence. material has d...
