— Although started as red indicator lights based on the GaP:N system, replacing only the nixie (Numeric Indicator eXperimental No. 1) tube, LEDs have become quite a high performance device of late and are revolutionizing the display and illumination sectors of our economy. Presently, the GaN based light emitters adorn the automobiles, traffic lights, moving(More)
Intervertebral disc (IVD) degeneration is considered a common cause of low back pain. In the degenerating IVD, the production of pro-inflammatory cytokines, including IL-1 and TNF-α, progressively increases, contributing to the degenerative process. Epoxyeicosatrienoic acids (EETs), synthesized from arachidonic acid by cytochrome P450 enzymes, act as(More)
Neuropathic pain (NP) is one of the most common complications after spinal cord injury (SCI), but no protein biomarkers has ever been introduced into clinical diagnosis. Previous studies implicated that toll-like receptor (TLR) 4 played a critical role in the development of NP in animal SCI models. Here, a total of 140 participants were recruited, 70 of(More)
The characteristics of current measuring methods of concrete pump discharge are analyzed, and the shortage of these methods is pointed out. According to the working principle of concrete pump, the mathematic model of the concrete pump discharge is established. The real-time measuring method of concrete pump discharge, which is based on pressure in the(More)
The measuring of the real-time discharge of concrete pump is an issue which must be solved urgently. The mathematic model of the concrete pump discharge is established based on the working principle of concrete pump. The measuring method based on pressure is put forward. By measuring and analyzing the pressure in the material cylinder, calculating the(More)
