Moon to Mars Planetary Autonomous Construction Technology’s (MMPACT) Microwave Structure Construction Capability (MSCC) team is developing the ability to prepare the lunar regolith and densify it into glass-ceramic landing pads and horizontal infrastructure. Microwave energy will be utilized to densify the lunar regolith. Some of the concept of operations, simulant and synthetic minerals, site preparation, design, microwave sintering, testing, & ancillary instrument technical challenges were listed. A current status of the MSCC project is also provided.
Considering the disadvantage of conventional huge and expensive bioelectrical impedance spectroscopy device,a rapid portable and inexpensive bioelectrical impedance spectroscopy device was developed.It consisted of a signal generator unit to outpu a sine wave,a detection unit,display and communicating units.The device could scan frequencies automatically which is range from 0.1 to 500 kHz.The device contacted the computer through RS232.Software was developed to obtain phase position,range,real par of impedance,imagery part of impedance and characteristic parameters of impedance.Coefficients of variability(CV) were applied to assess the stability of the system.Furthermore,84 porcine meat samples were selected to measure the bioelectrical impedance parameters using the device.In consequence,the results show good correlation(coefficient of determination R2 =0.75) between the impedance parameters and the moisture content value determined by standard chemical methods.It proved that the device we devel oped is one of the potential methods to predict moisture content of porcine meat.
Compared with other processes,CASS process has more variables to be controlled due to its complicated operation procedures.The automatic control system must be adopted to ensure the safety,reliability and continuity of wastewater treatment,meet the requirement of wastewater treatment process,and reduce the energy consumption and chemical consumption of the system effectively.The control strategies for coarse bar screen chamber,lifting pump station,fine bar screen chamber,cyclone-flow grit chamber,CASS reaction tank and air blowers are mainly introduced.
