The Asian corn borer (ACB), Ostrinia furnacalis, (Lepidoptera: Crambidae), a significant threat to corn crops, necessitates comprehensive research on its populations, across multiple clades. This study addresses the efficacy of various diets, such as an antibiotic mixed diet of amoxicillin mixed with artificial diet, wheat germ flour artificial diet and fresh corn leaves, for the successful mass rearing...
A new architecture of cable-free seismometers is designed based on advanced wireless network technology. The system is based on Wi-Fi and GPS by improvement of traditional cable based seismic exploration system. According to the specification, the protocol of application layer is designed. The interface of seismometer and wireless module is designed. Experiment shows that the system can work effectively.
With the purpose of investigating the thermal efficiency of steam-injection boiler, the thermal efficiency calculation model was built. Basing on the measured data from Xianhe oil production plant in Shengli oil filed, both energy efficiency and exergy efficiency were calculated and the boiler operation state was analyzed. Moreover, the influences of smoke temperature, excess air ratio and steam quality...
Based on the Navier-Stokes equations and the k-ɛ turbulent flow model, the numerical simulation was carried out for the water flows by using CFD program FLUENT. A new corrugated board structure in the oxidation ditch is proposed and the flow pattern and flow velocity distribution is calculated by using numerical simulation. The extended guide wall and the non-extended guide wall are also compared...
Considering the characteristics of complex structures in the oxidation ditch with eccentricity diversion wall,a numerical simulation was carried out for the water flows by using CFD program FLUENT. The radial eccentricity along the diversion wall from 0~1.0m and 0.25m interval for changes in the location of the eccentricity, the velocity of the flow field in the oxidation ditch are computed and analyzed...
