The commercial application results showed that the polymetallic reforming catalysts PRT exhibited high activity, good selectivity and stability. The performance of said catalysts could be restored completely through regeneration. After long period of operation, the activity of said catalysts still exhibited good sensitivity to temperature rise. Compared with the PR series catalysts, the PRT series catalysts had obviously better stability and lower coking rate. 展开更多

It has various parameters, and as yet has not been ex- tensively tested. The general applicability of the al- gorithm to a variety of problems is d. The aim of this work is to demonstrate the feas^ility and ro- bustness of the algorithm, and the sensitivity to the change of various parameters in a series of experi- ments for Nmap portscan detection by using DCA. Experiment results show that the algorithm per- forms well on the task of detecting a ping based Nmap portscan. Sensitivity analysis is also per- formed. True positive rate is higher for the detec- tion of anomaly processes and false positive rate is lower for the detection of normal orocesses. 展开更多

Edible mushrooms are considered as healthy food because they are low in calories and fat but rich in proteins minerals and dietary fiber(DF). Edible mushrooms are recognized as new potential resource of DF since the components of edible mushroom dietary fiber(EMDF) have shown special physiological and pharmacological effects on human and animals. In this article,the soluble and insoluble fractions of DF in different edible mushroom species have been evaluated. Biological effects of EMDF are related to promoting desired responses,for example,reducing blood cholesterol,protecting cells from free radicals attack by antioxidative effects,attenuating levels and fluctuations of blood glucose and selectively supporting the growth of beneficial gut bacteria. The EMDF plays an important role in reducing risk of cardiovascular diseases,diabetes mellitus and intestinal diseases. The non-starch polysaccharides(NSP),a kind of EMDF,is the best known and most potent mushroom-derived substances with antitumor and immunomodulatory properties. EMDF has also been reported to take part in the control of body weight,lipid homeostasis and insulin sensitivity due to its effect on specific chemical structures and physical properties. Many pharmaceutical substances with potent and unique health- enhancing properties were isolated recently from edible mushrooms and distributed worldwide. Mushroom-based dietary supplements(DSs) with potential therapeutic effects are produced from the mycelia or the fruiting bodies of mushrooms,and are consumed in the forms of capsules,tablets,or extracts. The EMDF, based on its special physiological functions on human health,shows a wide range of potential application prospects. 展开更多
