| 1 | Bioaccumulation of Heavy Metal in Wild Growing Mushrooms from Liangshan Yi Nationality Autonomous Prefecture,China显示文摘The heavy metal bioaccumulation levels of 13 species of mushrooms were studied. 13 different species of wild mush-rooms growing in China were analyzed for Cu, Zn, Pb, Cd, and As. Contents of Cu, Zn, Cd and Pb in mushroom and Cu, Zn in soil were tested by atomic absorption spectrometer (AAS), and As in samples by atomic fluorescent light (AFL). Contents of Cd and Pb in soil were analyzed by graphite furnace AAS. The results showed that contents of Cu, Pb, Cd, and As in Termitomyces microcarpus were the highest in the tested mushroom samples, which were 135.00, 13.28, 65.30, and 1.60 mg·kg-1 (dry biomass) respectively, and the corresponding bioconcentration factor (BCF) for Cu and Cd was 57 and 1 674 separately, which was the highest data in 13 mushroom species. The capability of Boletus griseus for Cd accumulation was very strong with BCF of 300. when people consume the wild edible mushrooms, contents of Cd and Pb should be greatly considered. | ZHANG Dan GAO Tingyan MA Pei LUO Ying SU Pengcheng | 2008 | Wuhan University Journal of Natural Sciences2008，13，3： | 9 |
| 2 | A Probabilistic View of Debris Flow显示文摘Most debris flows occur in valleys of area smaller than 50 km2. While associated with a valley, debris flow is by no means a full-valley event but originates from parts of the valley, i.e., the tributary sources. We propose that debris flow develops by extending from tributaries to the mainstream. The debris flow observed in the mainstream is the confluence of the tributary flows and the process of the confluence can be considered as a combination of the tributary elements. The frequency distribution of tributaries is found subject to the Weibull form (or its generalizations). And the same distribution form applies to the discharge of debris flow. Then the process of debris flow is related to the geometric structure of the valley. Moreover, viewed from a large scale of water system, all valleys are tributaries, which have been found to assume the same distribution. With each valley corresponding to a debris flow, the distribution can be taken as the frequency distribution of debris flow and therefore provides a quantitative description of the fact that debris flow is inclined to occur at valley of small size. Furthermore, different parameters appear in different regions, suggesting the regional differentials of debris flow potential. We can use the failure rate, instead of the size per se, to describe the risk of a valley of a given area. Finally we claim that the valleys of debris flow in different regions are in the similar episode of evolution. | LI Yong SU Pengcheng CUI Peng HU Kaiheng | 2008 | Journal of Mountain Science2008，5，2： | 7 |
| 3 | An α-expansin, VfEXPA1, is involved in regulation of stomatal movement in Vicia faba L.显示文摘The wall loosening of guard cells differs from other types of plant cells. However, the regulation of wall loosening during stomatal movement is poorly understood. VfEXPA1 is an α-expansin gene cloned from Vicia faba epidermal strips. Expression of VfEXPA1 is regulated by darkness and submergence, and is not affected by light and abscisic acid (ABA). In situ hybridization showed that VfEXPA1 is expressed primarily in the guard cells. Overexpression of VfEXPA1 in transgenic tobacco accelerated light-induced stomatal opening, and increased both transpiration and photosynthetic rates under favorable growth conditions. Our results indicate the guard cell-expressed expansin VfEXPA1 plays an important role in regulation of stomatal opening. | WEI PengCheng CHEN Su ZHANG XiuQing ZHAO Ping XIONG YanMei WANG WenLong CHEN Jia WANG XueChen | 2011 | Chinese Science Bulletin2011，56，33： | 4 |
| 4 | Unveiling the underlying mechanism of forming edge cracks upon high strain-rate rolling of magnesium alloy显示文摘In the current study,high strain-rate rolling(≥10 s-1) has been successfully employed to produce Mg-3 A1-1 Zn alloy sheets to a high reduction of 82% with a fine grain structure in a single pass.The underlying mechanism of forming primary and secondary edge cracks has been investigated.It is found that dynamic recrystallization(DRX) induced by subgrains tends to blunt cracks,while twinning-induced D RX is mainly observed around sharp crack tips.The motion of emitted dislocations from blunted cracks is inhibited by the DRX grain boundaries.This,on one hand,increases local work hardening,and on the other hand,causes stress concentration alo ng grain boundaries especially in the triple junctions leading to the formation of secondary cracks. | Biwu Zhu Xiao Liu Chao Xie Jing Su Pengcheng Guo Changping Tang Wenhui Liu | 2020 | Journal of Materials Science & Technology2020，47，15： | 2 |
| 5 | Seizures dynamics in a neural field model of cortical-thalamic circuitry显示文摘The focus of this study is to explore the mechanisms during seizure behavior using a physiologically motivated by corticothalamic circuity. The model is based on the assumption that, the inhibitory projects from thalamus reticular nucleus(TRN) to specific relay nuclei(SRN) are mediated by GABAA and GABAB receptors which react different time scales in synaptic transmission.Secondly, we include the effects of slow modulation on the threshold current of TRN population that were found to generate bursting behavior. Our model can reproduce healthy and pathological dynamics including wake, spindle, deep sleep, and also seizure states. In addition, contour maps are used to explore the transition of different activity states. It is worthy to point out seizure duration is significantly affected by a time-varying delay as illustrated in our numerical simulation. Finally, a reduced model ignoring the cerebral cortex mass can also capture the feature of spike wave discharge as generated in the full network. | ZHANG HongHui ZHENG YanHong SU JianZhong XIAO PengCheng | 2017 | Science China(Technological Sciences)2017，60，7： | 2 |
