We screened the bacteria with restoration and purification
functions in lake water and found that,Bacillus
subtilishad the highest water purification ability. Photosynthetic
bacteria, lactobacillus bacteria, nitrifying bacteria and oligotrophic bacteria
also showed different levels of lake water purification and restoration. L1873orthogonal experiments were designed to optimize the ratio of complex agents
to get the best ratio of various bacteria as 10g/LBacillus subtilis, 2g/L
photosynthetic bacteria, 0.8g/L lactobacillus, 0.6g/L nitrifying
bacteria 1, 0.4g/L nitrifying bacteria 2 and 0.6g/L oli-gotrophic
bacteria. When lake water was purified for 30 d under this ratio, total
phosphorus content decreased 85.90%, total nitrogen content decreased 70.96%, and
COD value decreased 81.19%.
Using sludge at the bottom of Hengshui Lake as samples,
and screened out the SJ-9 strain with PHA synthesis capability
by enrichment, purification, Nile blue staining, far-infrared spectroscopy and
gas qualitative and quantitative analysis. The infrared scanning of SJ-9
bacteria product showed that this product was middle chain PHA. Optimization of
SJ-9 fermentation conditions obtained the optimal conditions with optimal
carbon source of sodium butyrate, optimal C/N of 35, optimal fermentation time
of 120 h, and optimal initial pH for culture substrate of 7.0. 10 L fermenter
amplification culture under these conditions showed consistent results
with flask culture, and the bacteria and PHA had the highest yields at 120 h,
with the maximal yields of 6.81 and 2.36 g/L, respectively.
After about three years of the
sub-prime mortgage crisis, the American Congress passed its new financial
supervision bill on July 15, 2010, which is called Dodd-Frank Wall Street
Reform and Consumer Protection Act. This act was then singed to be in effect by
President Obama on July 21. This act is named as the most serious financial supervision act passed
ever since the Great Depression in 1933. This paper systematically reviews and
analyzes the background, major content, effect, and historical dimension of the
bill, and on this basis, it presents some implications to the financial governance
reform in emerging markets, such as the maintenance of a proper level of
financial deregulation, the
protection of interests of financial product consumers, the cultivation of ethical value and
social responsibility of financial executives or government leaders, etc.
It plays an important role in establishing and maintaining competitive advantages in multinational corporations (MNCs). MNCs transfer knowledge among parent corporations and foreign subsidiaries. While multinational firms tend to send outstanding expatriates to foreign subsidiaries to transfer knowledge. In this study, we theoretically indentify three dimensions during the knowledge transfer among expatriates and local staff: ability, motivation and seeking for the opportunities to transfer knowledge. Then we integrate the ability-motivation-opportunity with the absorptive capacity of corporations. The result shows that knowledge transfer from expatriates has indirect impact on performances of foreign subsidiaries, which will be stronger as the absorptive capacity of corporation becomes stronger.
With knowledge economy age’s coming, knowledge transfer is the significant method to make organization more competitive, and also help organizational innovation, which can help organization has its own core competence. Information processing is no longer the key bottleneck in the organization, the biggest challenge facing the organization, but the knowledge creation and transfer to promote a transnational knowledge transfer research in the ascendant. As in Taiwan, the economic downturn and the rising cost force Taiwan-funded enterprises to continue to find a way out, while the mainland has good infrastructure, abundant labor, and similar cultural background, so the mainland becomes the best choice of Taiwan businessmen. But even so, they still face the problem of the effectiveness of knowledge transfer. In this study, the relationship between the factors in the parent-subsidiary of Taiwan-funded starts to investigate the effectiveness of knowledge transfer from the communication channels, the level of trust, organizational distance and cultural distance four dimensions. Then we expand social communication channels to increase the knowledge, training, and the relevant recommendations to enhance the building of enterprise culture of high-tech enterprises.
With the rise and development of e-commerce, a huge impact is given on traditional retailing. Nowadays the retailing e-commerce competition is very fierce. In this paper nine possible developing directions of retailing e-commerce in future are discussed. By using interpretative structural modeling the direct correlation of these nine directions is analyzed, and then the development trend is divided into five stages involved the stage of mobile e-commerce retailing.
Using a sample of 252 R & D
teams in Guangzhou, Foshan, Shenzhen, the researcher empirically examines the
relationship between knowledge heterogeneity and knowledge innovation performance,
the mediating role of knowledge share. Results indicate that knowledge heterogeneity
is positively related to knowledge share, the same with knowledge share and
knowledge innovation performance. This paper analyzes the results comprehensively
and makes recommendations from multiple perspectives including building the
knowledge heterogeneous steams, advocating the collaborative spirit, building a
knowledge shared platform, improving the organizational structure, and grooming
