Carbon isotope ratios were used to survey the distribution of photosynthetic pathways among taxa, the relationship between photosynthetic pathway and habitat light levels, and the relationship between intercellular CO2 levels of C3 plants and habitat light levels within a subtropical monsoon forest in southern China. Of 128 species, most (94) possessed the(More)
Over the past decade there have been dramatic improvements in lidar technologies and the technology has been used successfully to estimate many forest parameters. While airborne small footprint lidar systems have been operational used in forest inventory and topographic mapping, large footprint lidar systems have demonstrated very potential results in(More)
A series of new palmatine derivatives with alkyl or alkyl with N-heterocyclic structures were designed and synthesized at C-9-O according to the principle of association. These compounds were characterised by (1)H NMR, (13)C NMR, ESI-MS and elemental analysis, and tested for their antimicrobial activity in vitro to evaluate structure-activity relationships.(More)
We present a model and applications analysis of the switching characteristic of electrolyte-oxide-semiconductor (EOS) structure diodes. The EOS structure consists of a heavily-doped silicon layer, an SiO<sub>2</sub> layer, and an electrolyte-solution layer, and exhibits diode characteristics when a sweeping voltage is applied. A conduction model of the(More)
We find that the Electrolyte-Oxide-Semiconductor (EOS) structure, which is utilized a lot in micro/nanofluidic devices, is not perfectly insulated as previously believed. There is a significant leakage current through the insulator, and the I-V relationship shows one-way conductivity like a diode. We build a model considering the implantation of ions under(More)
A general procedure for the determination of the first double bond position in the side-chain of a phenolic lipid has been investigated and, in the first place, the phenols of natural cashew nut-shell liquid (Anacardium occidentale) have been examined. An improved oxidative degradation procedure has been applied consisting of methylation by the phase(More)
