Inhibition Effect of Vanadate-replaced Polyoxometalates on Mushroom Tyrosinase

Numerical solutions of diode-pumped dual-loss-modulated Q-switched and mode-locked green laser with acousto-optic modulator and Cr4+: YAG saturable absorber

“…The relationship between the thermal focal length f T and the incident pump power P in could be expressed by f T = 2πK c δ n + α T n 1 ⋅ w 2 p ξP in η [21,22], where K c is the thermal conductivity of the active medium, δ n is the thermal chromatic dispersion coefficient of active medium, α T is the thermal expansion coefficient of active medium, ξ is the thermal load ratio between the power converted into heat and absorbed in the active medium, P in is the pump power, η is the absorptivity of the active medium, n 1 is the refractive indices of the active medium. According to the thermal lens length, the beam radius, which can be obtained by ABCD transmission matrix theory, versus the pump power in the middle of the laser crystal, AO modulator and the saturable absorber were calculated and shown in Fig.…”

Effects of Stale Refuse from Informal Landfill on Seed Germination of <i>Lolium perenne L.</i>

“…This is very harmful to the sustainable development of agriculture, especially in the land insufficiency areas of China, such as the Three Gorges Reservoir Areas. Therefore, the method of using aged refuse as lawn cultivation matrix can not only solve the problem of waste disposal, but also promote the sustainable development of agriculture, forestry and soil conservation [11,12]. And heavy metals do not enter the food chain of humans in this course.…”
