Microcystin-LR (MC-LR) and microcystin-RR (MC-RR) produced by harmful cyanobacterial blooms (HCBs) pose substantial threats to the ecosystem and public health due to their potential hepatotoxicity. Degradation of microcystins (MCs) by indigenous bacteria represents a promising method for removing MCs from fresh water without harming the aquatic environment,(More)
Microcystin-LR (MC-LR) and microcystin-RR (MC-RR) are the two most common microcystins (MCs) present in fresh water posing a direct threat to public health because of their hepatotoxicity. A novel MC-degrading bacterium designated MC-LTH1 capable of degrading MC-LR and -RR was isolated, and the degradation rates and mechanisms of MC-LR and -RR for this(More)
In order to improve the eye diagram performance of output current in vertical-cavity surface-emitting laser (VCSEL) driver, the influence made by bond wire on high speed output waveform is discussed in this paper, based on a practical VCSEL model with bond wire inductance. A technique based on pre-emphasis is used to compensate the output current waveform.(More)
This article presents the design of a driver system for vertical cavity surface emitting lasers (VCSELs), including limiting amplifier, delay circuit, driver circuit and 5-bits DAC. By adding a delayed pulse on the original data signal, the VCSEL driver adopts a new method to compensate the ringing generated by the bound-wire inductance, pad capacitance and(More)
Electrospun polymer nanofibres were used as novel solid-phase extraction (SPE) sorbents to extract and quantify the microcystins (MCs) including microcystin-RR (MC-RR) and microcystin-LR (MC-LR) from in-suit water samples. The parameters that influenced the extraction efficiency were studied, including the amount of nanofibre, eluted solvent, eluted volume,(More)
