First, an integrated advanced geological predic- tion was developed for tunneling in karst area. Then, a new system of ventilation by involving the dedusting technol- ogy was proposed and used in the field, which received a good air quality. Finally, a method to minimize the dis- tance between the working face and the invert installation was proposed by optimizing the invert installation and adopting the micro bench method. Applying the method to the project obtained an excellent result. The achievement obtained for this study would be able to provide a valuable reference to similar projects in the future.展开更多

It has benefited greatly from the recent technological advances in the field of systems biology. DNA microarray, phenome, interactome and transcriptome mapping, the new generation of deep sequencing technologies, and faster and better computational and modeling approaches have opened new frontiers for both systems biologists and developmental biologists to reexamine the old developmental biology questions, such as pattern formation, and to tackle new problems, such as stem cell reprogramming. As showcased in the International Developmental Systems Biology Symposium organized by Chinese Academy of Sciences, developmental systems biology is flourishing in many perspectives, from the evolution of developmental systems, to the underlying genetic and molecular pathways and networks, to the genomic, epigenomic and noncoding levels, to the computational analysis and modeling. We believe that the field will continue to reap rewards into the future with these new approaches.展开更多

This is not conducive to the sustainable and healthy development of the construction industry and even the national economy. Therefore, the construction industry needs to implement energy conservation and consumption reduction, strengthen the application of new energy-saving materials and processes, improve the application level of new building materials and processes, optimize the overall building quality, and comprehensively promote the development of China's construction field. Therefore, it is necessary to strengthen research, improvement, innovation, promotion and application of energy-saving materials and processes to realize the sustainable and healthy development of China's construction industry.展开更多

Agricultural machinery management and the promotion of new technologies can provide impetus for the development of agriculture. However, in the actual process of management and application of technology, there are still deficiencies. Yunnan Province has a large number of agricultural workers. In order to promote the development of local agricultural mechanization, it is necessary to actively promote the management of agricultural machinery and the promotion and application of new technologies in combination with local conditions. Therefore, this paper analyzes and discusses the management of agricultural machinery and the popularization and application of new agricultural machinery technologies in Yunnan.展开更多

This paper aims to study the impact of information and communication technologies (ICTs) on remoteness and exclusion. It utilises two models - the resource movement framework,and the "information chain" - to analyse a telecentre in one district of mountainous Huancavelica,Peru's poorest region,set in the high Andes. It finds ICTs enabling new and positive resource flows for the two key user groups:teenaged school students and young farmers. These help to maintain social networks. They also support information searches that have improved agricultural practice where other information chain resources have been available. But non-use and ineffective use of the telecentre are found where information chain resources are lacking. ICTs have some impacts on intangible elements of remoteness. In this particular example,they also offer access to some previously-excluded resources. But they have not really addressed the systematic exclusions faced by mountain communities. And they so far appear to be a technology of inequality; favouring those residents who begin with better resource endowments.The paper concludes by offering some recommendations for mountain ICT project practice.展开更多
