The comprehensive land carrying capacities of seven cities in the Shandong Peninsula Blue Economic Zone between 2007&ndash, 2014 were assessed using a multi-criterion comprehensive evaluation approach and an index of 27 indicators, and cluster analysis was conducted to identify the spatial-temporal variations of the cities&rsquo, comprehensive land carrying capacities. The results showed that the carrying capacity of the water and soil resources of the cities had declined except Dongying City, in contrast, the carrying capacities of the eco-environment, the social resources and the economy and technology of the seven cities had all arisen. The carrying capacities of social resources of Dongying and Weihai were markedly higher than the other five cities. The carrying capacities of economy and technology of Qingdao and Dongying were high, the capacities of Weihai and Yantai were moderate, and the capacities of Weifang, Rizhao, and Binzhou were low. In general, the comprehensive land carrying capacities of the eastern cities were higher than those of the western cities, which was similar to the spatial pattern of the economy development of those cities. In addition, positive correlations were identified between the comprehensive land carrying capacity and the per capita land for construction, areal proportion of wetland to total land, percentage of green space to build up area, per capita public green space, comprehensive utilization rate of industrial solid waste residues, urbanization rate, area of per capita urban road, per capita GDP, economy density, fixed-assets investment per area, etc. However negative correlations were discovered between the comprehensive land carrying capacity and the discharge of industrial waste water per 10,000 Yuan RMB GDP, as well as the proportion of added value of the primary industry to total GDP. Finally, we discussed measures to improve the comprehensive land carrying capacities of the cities, such as elevating the intensive land utilization and economic development, decreasing the proportion of added value of the primary industry to total GDP, promoting energy saving and emission reduction, etc.

Embedded block coding with optimized truncation (EBCOT) with the wavelet shape of tree encoding structure is more flexible because it encodes each code block respectively by decomposing the subband into code blocks, so that the embedded code streams will come into being to support the mass classification, the hierarchical resolution and the random access. However the anti-missing performance via network of the algorithm is worse. The source signal has been divided into many code streams by multi-description coding (MDC) of image and video so that it will be transferred through the insecure transmission channel. Region of Interest (ROI) coding gives priority to the focus of doctor's interest generally occupies lesser part of entire medical image. In this paper, ROI coding, which combines MDC and EBCOT, has been done according to JPEG2000 ROI coding standard in medical images. The algorithm not only uses the hierarchical spatial resolution and random access to ROI of EBCOT, but also has improved the anti-missing performance via network, and formed robust code stream. The experimental results demonstrated that the coding method improved the system compression ratio without influence on the medical diagnosis.

Earlier studies from this laboratory demonstrated the ability of lens epithelium to synthesize new Na,K-adenosine triphosphatase (Na,K-ATPase) catalytic subunit (alpha) polypeptide under conditions of increased ion permeability. In the present study, the authors considered whether continuous synthesis of Na,K-ATPase protein is necessary for maintenance of Na,K-ATPase activity in lens cells.Na,K-ATPase activity was measured by quantifying the ouabain-sensitive rate of ATP hydrolysis in cultured human lens epithelial cells (HLE-B3) permeabilized with digitonin. The abundance of Na,K-ATPase alpha subunit was determined by Western blot analysis. Synthesis of Na,K-ATPase alpha1 polypeptide was investigated by measuring 35S-methionine incorporation.Na,K-ATPase activity was reduced to less than 20% of the control level in HLE-B3 cells exposed to 100 microM cycloheximide for 24 hours. However, as judged by Western blot density, the abundance of Na,K-ATPase alpha1 and alpha3 subunit in cycloheximide-treated cells was 90% and 84% of the control level, respectively. 35S-methionine incorporation experiments revealed detectable labeling of Na,K-ATPase alpha1 subunit polypeptide within 30 minutes, consistent with alpha1 polypeptide synthesis. Na,K-ATPase alpha1 polypeptide labeling was also detected in the epithelium of intact rat lenses that had been allowed to incorporate 35S-methionine. Cycloheximide abolished 35S-methionine incorporation into Na,K-ATPase alpha1 subunit polypeptide of HLE-B3 cells. When added during the chase phase of the experiment, cycloheximide was found to slow the disappearance of labeled alpha1 polypeptide, consistent with a reduced rate of polypeptide degradation.The results suggest that a continuous cycle of Na,K-ATPase alpha1 synthesis and degradation may occur in lens epithelial cells. Cycloheximide appeared to inhibit Na,K-ATPase protein synthesis and degradation. The observed reduction of Na,K-ATPase activity after treatment with cycloheximide indicates that even though Na,K-ATPase remains abundant, Na,K-ATPase becomes inactivated when protein synthesis is inhibited.
