The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development(AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.

Objective. To investigate the peritoneum as a material using in the portal vein reconstruction. Methods. Twenty-one small healthy domestic pigs were used in the study, and divided into two groups. The observation period was twenty-four weeks, and divided into three stages. A section of portal vein about 2. 5- 3. 0 cm long was resected and replaced by autogenous peritoneum tube(APT)and autoge- nous vein *** liver function tests, bloodflow dynamic examination, patency and pathological changes of the grafts were. investigaed after the replacement. *** animals survived the operation and the subsequent observation. It showed that aspartate transminase (AST) were mlidly elevated just after operation but recovered quickly in both groups. Portal bloodflow index(PI)and portal pressure were both a little higher than those before operations but all within normal range. Portography revealed a total patency of eight out of thirteen grafts in the experiment group, whereas a total patency of six out of eight in the control group. During the observation, portograhpy re- vealed five out of thirteen APT grafts were occluded in the experiment group, whereas two out of eight grafts were occluded in the control group. No dilatation grafts were seen. Abundant collaterals were seen around the occlusive graft. After twelve weeks of reconstruction, scanning electron microscopy revealed that APT grafts were covered with a layer of endothelial--like cells with a certain arranging direction. Conclusion. Peritoneum is a perspective self-material for portal reconstruction. Long-term patency of the APT were a little lower than that of the autogenous vein. It is worth further studying.

Using an identical monolithic InGaN/GaN light emitting diode (LED) array as the sensing module and a well-designed data processing module, we demonstrate a small-size concentration sensing prototype. Overlap between the emission and the response spectra of the InGaN/GaN LED makes each pair of LEDs in the arrayed chip form a sensing channel. The changes in liquid concentration can be transformed into variation of photocurrent. The system's sensing properties are further optimized by varying the position, number of receivers, and packaging reflectors. With methyl orange as a tracer agent, the sensing system's resolution is 0.286 μmol/L with a linear measurement region below 40 μmol/L.

随着20世纪后半期以来,节庆以史无前例的规模复兴,在现代性的语境下,节庆与社区存续、复兴或衰亡的各种关系,成为文化地理关注的主题。文章从传统社区的延续与现代认同的重构、移民社区的再造与多元认同的杂糅、社区活力的再生与地方品牌的营销、社区秩序的重塑与地方权力的协商4个方面,对节庆与社区重构的关系进行分析。结论认为:节庆与社区重构之间具有紧密的关系,社区并没有被现代性力量所终结,而是以一种更加复杂化的形式存续和发展,或者延续传统的社区秩序,或者吸纳外来和创新要素重构出混杂的社区秩序,或者进行地方营销扩大社区影响;社区节庆则被全球化、市场化等现代性力量不断调整和创新。最后在此基础上进一步展望中国语境下的社区重构研究。
