Here we report the identification and analysis of a T-DNA insertion mutant of PDS3 gene. Functional complementation confirmed that both the albino and dwarfphenotypes ofthepds3 mutant resulted from functional disruption of the PDS3 gene. Chloroplast development was arrested at the proplastid stage in thepds3 mutant. Further analysis showed that high level ofphytoene was accumulated in the pds3 mutant. Addition of exogenous GA3 could partially rescue the dwarf phenotype, suggesting that the dwarf phenotype ofthepds3 mutant might be due to GA deficiency. Microarray and RT-PCR analysis showed that disrupting PDS3 gene resulted in gene expression changes involved in at least 20 metabolic pathways, including the inhibition of many genes in carotenoid, chlorophyll, and GA biosynthesis pathways. Our data suggest that the accumulated phytoene in the pds3 mutant might play an important role in certain negative feedbacks to affect gene expression of diverse cellular pathways.展开更多

Because of family miniaturization, core, and currently limited social accumulation are difficult to meet the demand of the elderly in long-term care.Community provides the elderly long-term care services, and provides the elderly all kinds of household helping services. They just make up for the inadequacy of the family and society.And how to make the community elderly long-term care services become more suitable for the needs of the elderly at home, provide better service for the elderly, are our current problems to be solved.展开更多

The results show teachers’ willingness to use TBLT. They adopt flexible teaching procedures, apply TBLT creatively, and explore task-based language assessment. The authors argue for inclusive non-doctrinaire approaches to TBLT, and propose to construct localized TBLT theory and practice with Chinese characteristics.展开更多

However, evidence shows that SMEs are increasingly internationalizing their activities in order to enrich their resource pool. In this regard, a reinterpretation of the OLI paradigm came out with a new perspective suggesting that "foreign direct investmenf' (FDI) is increasingly oriented toward asset augmentation. Correspondingly, the purpose of this theoretical paper is to suggest a set of principles that could inform on how global small and medium-sized enterprises grow in the international marketplace when investing abroad.展开更多

Meanwhile, due to various reasons, our enterprises have not yet fully out of the shadow of the economic crisis, the development of small and medium enterprises are facing various bottlenecks. In this study, incentive theory put forward a more systematic incentive policy from the perspective of positive psychology. On personal level, training employee's positive personality, inspiring their self-efficacy, providing multi-faceted training, all this can contribute to positive psychological capital. At the organizational level, by building a positive organizational culture and creating an organizational relationship full of love to contribute to good incentive effect.展开更多

This method can make the production fast and effective at small series or frequent manufacturing changes. The shop-floor control method, presented in this paper, offers a solution for the facing problem of fast and easy reconfiguration. The hardware of the controller designed modular with software components for online configuration. This solution allows sensor integration on different levels for every part of the manufacturing cell. With unified programming language and the machine specific controllers (post-processing) the cells can be defined easily by different types of human-machine interaction. The shop-floor control architecture is implemented and validated on an Adept SCARA (selective compliance assembly robot arm) robot. The robot is driven by standalone, low-level, interchangeable, software and hardware components.展开更多

If CAD technology is first innovation of information technology in construction industry, then the emergence of the BIM technology shall fully deserved to be treated as a second innovation in construction industry. As a new technology which have been introduced to China in recent years, BIM technology already had its major application in foreigner countries .This paper focuses on the current status of BIM technology application in our country, especially on some small and medium enterprises using the traditional BIM technology to handle the project which have complex usage,creative deign and cost limitation. Firstly,we take a deep analysis on the initial application situation. Then we go through the practical application and analyse what benefit can be given to a project from BIM technology. Finally, analyse the problems and solutions in BIM application with consideration of Chinese building engineering development. Only after a careful analysis, a deep understanding of BIM, we can fully understand this new technology and make BIM to give its value to construction project.展开更多
