Prominent neurologists and movement disorders experts from around the world logically and systematically review the major movement disorder emergencies, instructing the reader on how optimally to recognize and manage these problems. The authors comprehensively cover a broad range of disorders, including acute dystonic reactions, neuroleptic malignant syndrome, startle syndromes, and tic emergencies, and stress the importance of certain obvious diagnoses such as Wilson's disease, dopa-responsive dystonia, and Whipple's disease, in which delayed diagnosis in less emergent situations can lead to slowly evolving and often irreversible neurologic damage with tragic consequences. Patient vignettes at the beginning of each chapter focus the reader's attention and highlight the urgency of the problem. Since astute clinical diagnosis of many movement disorders is still largely dependent on visual pattern recognition in the clinic, an accompanying CD-ROM illustrates virtually all of the movement disorders described in the text

Irradiation-induced impurity segregation to grain boundaries is one of the important radiation effects on materials. For this reason, phosphorus segregation to prior austenite grain boundaries in a P-doped 2.25Cr1Mo steel subjected to neutron irradiation is examined using field emission gun scanning transmission electron microscopy (FEGSTEM) with energy dispersive X-ray microanalysis (EDX). The steel samples are irradiated around 270 and 400℃, respectively. The irradiation dose rate and dose are -1.05×10-8 dpa/s and -0.042 dpa respectively for 270℃ irradiation, and 1.7×10-8 dpa/s and 0.13 dpa respectively for 400℃ irradiation. The FEGSTEM results indicate that there is no apparent phosphorus segregation during 270℃ irradiation but there is some during 400℃ irradiation.

China & World Economy 2007年第5期15卷 107-120页

作者： Xiuqing Zou Arie j. Oskam Associate Professor Jiangxi University of Finance and Economics Nanchang China Professor of Agricultural Economics and Rural Policy Wageningen University the Netherlands

This paper explores a new compensation standard for use in agricultural land conversion in China during the land-expropriation process, based on the market value definition. Assuming identical bargainingpower between the buyer and the seller, efficient and equitable compensation is obtained through a market transaction and bargaining negotiation mechanism, under the assumpation of a perfect market. From the state-of-the-art viewpoint of land appraising, a practical approximation of the theoretical optimal compensation will provide an effective solution for China, under the current collective-owned land property rights structure.

Three-dimensional Prussian blue (PB) nanostructures was obtained via a one-step hydrothermal method. Subsequently, two-dimensional tin disulfide (SnS2) nanosheets were grown onto PB through a facile hydrothermal synthesis. The as prepared SnS2/PB is further employed as the anode of sodium ion batteries (SIBs). S11S2/PB nanoarchitecture delivers a specific capacity of 725.7 mAh·g-1 at 50 mA·g-1. When put through more than 200 cycles, it achieved a stable cycling capacity of 400 m Ah·g^-1 at 200 m A·g^i. The stable Na^+ storage properties of SnS2/PB was attributed to the synergistic effect among the conductive PB carbon, used as the template in this work. These results obtained potentially paves the way for the development of excellent electrochemical performance with stable performance of SIBs.
