A laccase was purified from Trametes hirsuta. This laccase was classified as a “white” or “yellow” laccase. pH 2.4 was optimal for the oxidation of ABTS and pH 2.5 for DMP. DMP oxidation was optimal at 85°C. The half-life of this laccase was 70 min at 75°C, and 5 h at 65°C. Non-phenolic dyes, such as Methyl Red, were oxidized by purified laccase without(More)
A new image fusion algorithm based on wavelet transform is proposed, according to the directional characteristics of the high-frequency. Using wavelet transform decomposes an image into low-frequency sub-bands and high-frequency sub-bands in different scale, low-frequency sub-band using the correlation coefficients based on spatial frequency to determine(More)
The pepsin and trypsin activities and some of the properties of the two enzymes of southern sheatfish larvae were studied. The results were as follows: the highest level of trypsin activity is in the foregut in all measured tissues; from foregut to hindgut, trypsin activities decrease; the pH optimum of trypsin activity is pH9.0; the strongest pepsin(More)

Since their discovery nearly thirty years ago, γ-ray bursts (GRBs) have made one of the biggest mysteries in astrophysics, primarily because they have remained invisible at wavelengths other than γ-rays so that the distances are unknown. The recent detection of X-ray, optical and even radio afterglows from some GRBs located by the Italian-Dutch BeppoSAX(More)
Various dust patterns are observed in an rf discharge dusty plasma system. According to the dust growth process from small to large in size, the formation of different dust patterns can be divided into two stages: the small-particle stage (or dust cloud stage), and the large-particle stage (or dust crystal stage). The evolution relations between different(More)
