Iron (Fe) is an essential micronutrient that participates in various biological processes important for plant growth. Ethylene production induced by Fe deficiency plays important roles in plant tolerance to stress induced by Fe deficiency. However, the activation and regulatory mechanisms of 1-Aminocyclopropane-1-carboxylic acid synthase (ACS) genes in this(More)
Nesfatin-1 is a novel anorexigenic hormone which has close relationship with diabetes, obese, anorexia nervosa, psychiatric disorders and neurogenic diseases. The aim of our study was to evaluate levels of plasma nesfatin-1 among patients presenting with coronary artery disease and the correlation between nesfatin-1 levels and other clinical parameters.(More)
The characteristic of broadband satellite communication system is introduced simply and the significance of channel simulator is analyzed. The broadband satellite channel model is established which puts on emphasis upon the effects of power amplifier nonlinearity, rain attenuation and propagation delay. Finally the hardware implementation of a kind of(More)
The nonlinearity characteristic in satellite channel will causes spectrum regrowth and adjacent channel interference, which may have bad influence on communication system. In order to compensate for nonlinear distortion in satellite channel, combining with 16APSK, a digital baseband predistortion method based on Look-Up Table (LUT) is studied. Simulation(More)
