Seasonality of insect succession on exposed rabbit carrion in Guangzhou, China

引用

Insect Science 2009年第5期16卷 425-439页

作者： Yan-Wei Shi Xiao-shan Liu Hai-yang Wang Run-Jie Zhang State Key Lab for Bio-control and Institute of Entomology Sun Yat-Sen University Guangzhou China

Succession patterns for insect fauna, spanning four seasons, on rabbit carcasses were studied in Guangzhou China from 2006 to 2008. A total of 49 taxa belonging to three orders and 15 families were collected and identified. Four decomposition stages were recognized： fresh, bloated, decay and dry stage. Taxa diversity was higher in bloated and decay stages than fresh and dry stages. Internal and ambient temperatures were measured. Maximum internal temperature arrived earlier in warmer seasons. The sequence of insect succession in this study follows the same general patterns： the Diptera peaked initially, and the Coleoptera peaked later. Chrysomya megacephala was the dominant species in four seasons. Its time point of different development stages on carrion could be the most important indicators for PMI （postmortem interval） estimation in Guangzhou. Yearly and seasonal differences in activities of insects were compared. Alpha diversity indices were calculated. There were no significant differences in shannon-Wiener index, evenness （J） and dominance （C） between seasons and years. From the Jaccard similarity index, the highest similarity was between winter and spring, while the lowest was between summer and winter. Some species occurring exclusively in one season may be important to characterize different seasons. A list of the insect taxa associated with above-ground rabbit carrion during the four seasons was compiled, which can be used for estimating time since death in similar bio-climate areas.

Effect of Extrusion Strain Path on Microstructure and Properties of AZ31 Magnesium Alloy Sheet

引用

Acta Metallurgica Sinica(English Letters) 2015年第10期28卷 1257-1263页

作者： Qing-shan yang Bin Jiang Zu-Jian Yu Qing-Wei Dai Su-Qin Luo School of Metallurgy and Material Engineering Chongqing University of Science and Technology Chongqing Academy of Science and Technology

The mechanical properties of AZ31 magnesium alloy sheets processed by different extrusion strain paths were examined in correlation with concurrent microstructure and texture evolution. The conventional extrusion（CE） and asymmetric extrusion（ASE） paths were performed on Mg alloy sheets. The textures at near surface and mid-layer of ASE sheets were various throughout sheet thickness direction as a result of extra asymmetric shear strain. This can stimulate the orientation of（0002） basal planes to incline approximately 12° toward the shear direction. Moreover, the basal texture of ASE sheet was weakened compared with CE one. Enhancing the ambient formability of extruded Mg alloy sheet fabricated by ASE path was accomplished by the tilted weak basal texture.

Purification and Characterization of a Proteolytic Enzyme from Fig Latex

Chemical Research in Chinese Universities 2008年第3期24卷 348-352页

作者： HUANG Lu QU He-zhi ZHANG Lei DU shan-shan yang Shuo HAO Dong-yun WANG Xiao-ping Key Laboratory of Molecular Enzymology ＆ Engineering of Ministry of Educational Jilin University Changehun 130021 P. R. China

Ficin is an important component of plants in Ficus family such as fig latex. It is of special significance in medicine and industry because it exhibits activity throughout a wide range of temperature and pH values. In this work, we purified a component of ficin from the latex homogeneity of shandong fig trees, and the properties of the purified ficin were studied. The current findings revealed that heavy metal ions were able to inhibit ficin, while DTT, L-cysteine, and β-ME were found to promote ficin activity. It was also observed that the half life of ficin at 65 °C was longer than 1 h and the Michaelis constant（Km） for casein hydrolyzation was determined to be 1.56 mg/mL. Our study shows that this purified ficin is a cysteine protease.
