Extraction of Triterpenoids with Antioxidant and Anti-tumor Activity from Agrocybe aegerita Mycelium and Spent Culture Medium

Different organic solvents (petroleum ether, ethyl acetate and ethanol) were used to extract A. aegerita mycelium and spent culture medium following growth of the fungus in submerged culture. All the extracts exhibited antioxidant and anti-tumor activity that may be linked to triterpenoids present in the extracts.     

荔枝根、茎温度对芽休眠和花诱导的影响

荔枝常因初花少而出现结果数低而不稳的情况。初花少的主要原因是出芽前茎没有休眠的缘故。在正常情况下持续休眠是由低温或水分胁迫诱导的，只是没有低温的情况下，水分胁迫诱导的休眠并不足以诱导开花。尚未见荔枝根、茎温度对芽休眠和茎发育的影     

黄杨绢野螟发生期的预测

黄杨绢野螟危害爪子黄杨,雀舌黄杨叶片,嫩芽,影响其生长和观赏,严重时,造成整株枯死。能否准确预报出该虫各虫态的发生期,是防治该虫成几的关键。经室内多代变温饲养测定结果是：越冬代蛹期Ｃ＝１３．４０±１．２４（℃）,Ｋ＝１１５．８７±１３．５０（ＤＤ）;第１代;卵期Ｃ＝１３．８７±１．７９（℃）,Ｋ＝４２．６４±６．５９（ＤＤ）;幼虫期Ｃ＝１３．４０±０．１０（Ｃ）,Ｋ＝３２７．４５±６７．７６（ＤＤ     

A time-varying signal processing method for Coriolis mass flowmeter

The mass flowrate of Coriolis mass flowmeter in practical application has slow changes with time. To solve the problem, an improved time-varying signal model whose frequency, amplitude and phase are time-varying based on the random walk model is established firstly. A new algorithm of adaptive notch filter with the capability of tracking frequency variation is applied to filter the sensor output signal of Coriolis mass flowmeter and its frequency is calculated next. An adaptive line enhancer based on the mentioned notch filter extracts fundamental frequency signal from noisy data. Then, by short window intercepting, the revised sliding DTFT recursive algorithm is introduced to calculate the real-time phase difference between two enhanced signals. With the frequency and phase difference obtained, the time interval between the two signals is calculated and then the mass flowrate is derived. The simulations and field test results show that the proposed method can not only track the change of frequency and phase, but also ensure the calculation accuracy when measuring small phase difference. The computational load of the algorithm is simple so that it can be applied to real-time signal processing for Coriolis mass flowmeter.
