Effects of Ca2+ on nitrogen metabolism in wheat seedlings exposed to salt stress

Wang ZhiQiang,and Lin TongBao,

生态学报 , 2009,
Abstract: To seek ways for improving salt\|tolerance of wheat plants, experiments were conducted to examine the ameliorative effects of Ca2+ on nitrogen metabolism under salt stress using an ordinary wheat cultivar (Triticum aestivum L. cv. Yumai 34) as the material. The wheat seedlings were cultured in full nutrient solution. The first leaf being fully expanded, different treatments were initiated by culturing the plants in the nutrient solution without calcium. NaCl (150 mmol?L-1 and 300 mmol?L-1) and combinations of NaCl + Ca2+ (150 mmol?L-1 + 4 mmol?L-1 and 300 mmol?L-1 + 4 mmol?L-1) were applied to the growing plants using no salt\|stressed plants as control. After 5 days of treatments, the activities of nitrogen assimilation enzymes, the amount of nitrogen assimilation and the growth status of wheat seedlings were determined. The results showed that Ca2+ significantly alleviated the depressed\|growth of wheat seedlings under low salt stress, manifesting the enhanced fresh weight, chlorophyll and soluble protein contents; while Ca2+ did not show obvious ameliorative effects under high salt stress. Ca2+ promoted the nitrogen assimilation and improved the status of nitrogen nutrition in wheat plants exposed to low salt stress, which could be mainly due to the enhanced activities of nitrate reductase (NR), glutamine synthetase (GS) and NADP\|dependent isocitrate dehydrogenase (NADP\|ICDH). The minor ameliorative effects of Ca2+ on nitrogen assimilation in wheat seedlings under high salt stress could be explained by the insignificant increase of NADP\|ICDH activity.

On Building VSAT Backbone Network of SSTCC

Chen Tongbao Fu Qiang,

现代图书情报技术 , 1997,
Abstract: The National Scientific and Technical lnformation Network (STINet) has reached a certain size after two year development, But the developing speed is reduced due to the over-high telecommunication cost. So the State Science and Technology Committee of China (SSTCC) has decided to set up the VSAT backbone network which will provide STINet with a communication platform to reduce the telecommunication cost and provide a unified transferring platform for other systems and networks of SSTCC. The article introduces and analyses the current situation of STINet, the possibility and the structur of the above project, the VAST network of SSTCC.
Phase Identification Using Series of Selected Area Diffraction Patterns and Energy Dispersive Spectrometry within TEM  [PDF]
Kun-Lin Lin
Microscopy Research (MR) , 2014, DOI: 10.4236/mr.2014.24008
Abstract: Transmission electron microscopy (TEM) is a very powerful technique for materials characteriza-tion, providing information relating to morphology, composition, and crystal structure. Selected area diffraction patterns (SADPs) are crystallographic data that can be obtained using a TEM in-strument. Conventional identification through SADP/TEM is tricky and tedious, thereby increasing the difficulty of phase identification. To establish a procedure for phase identification of known and unknown phases, in this study we examined two samples: one, a known phase, was Si with <100> alignment; the other, unknown, was the TixOy phase at the 96.4Au-3Ni-0.6Ti interlayer/ yttria-stabilized zirconia (YSZ) interface of a steel/96.4Au-3Ni-0.6Ti interlayer/YSZ joint. The procedures for phase identification of the known and unknown phases are described herein using a series of SADPs and energy dispersive spectrometry within TEM that would be useful for general researchers.
Research on the Impact of Supply Chain Integration of Startups: Service Supply Chain Perspective  [PDF]
Han Lin, Qian Lin
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.64022
As the potential power of social economic development, the importance of startups has attracted more and more attention from academia. The service supply chain, led by the service integrator, can help the startups to improve the performance of the enterprise, achieve better supply chain integration, and go through their “infancy” period successfully. However, the research about the factors that influence the integration of service supply chain and how these factors affect the supply chain integration of startups remains to be explored. Based on the practical problems and theoretical research status above, this study constructs a theoretical hypothesis model of the relationship between interaction, supply chain finance and supply chain integration, and we take the survey data of 65 startups in Pearl River Delta of China as samples and use hierarchical regression analysis to carry out hypothesis testing. The result shows that, from the perspective of startups, interaction has a positive impact on supplier integration, internal integration and customer integration, and supply chain finance has a positive impact on internal integration. The main significance of this study is to make up for the vacancy on this part of the academic community in the service supply chain, and help provide some reference basis for start-up enterprises’ supply chain integration.
Influence of Dams on River Ecosystem and Its Countermeasures  [PDF]
Qicai Lin
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.31007
Abstract: Dam construction is an important engineering measure in dealing with the relationship between water and human being. However, with dam construction, some disadvantages to the river basin may be caused, including flow flux of downstream changed, flooded area reduced, river species and other organisms changed and substance sedimentation. Furthermore, it brings some diseases to human being and human residential areas reduced too. Based on the basic principles of ecohydralic engineering, some countermeasures to minimize the negative effects on rivers were put forward. They are reservoir ecological regulation, ecohydraulic engineering construction and comprehensive water pollution treatment.
Disciplinization of History Education in Modern China: A Study of History Education in the Imperial University of Peking (1898-1911)  [PDF]

Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34084
Abstract: Through a thorough investigation on the history education in the Imperial University of Peking from 1898 to 1911, this paper attempts to highlight the following findings. 1) The disciplinization of history education and the transformation of traditional historiography were concurrently incepted in the late Qing period. The Imperial University of Peking served as a pivotal platform for the realization of this synchronous process. 2) History instructors and students of this university can be regarded as initial participants in the new school system, as well as pioneering practitioners of the New History. 3) Zhongti xiyong, as the fundamental tenet of this university, in actual practice, was utilized as a slogan for justifying the introduction of Western learning. 4) Japan exerted tremendous influence on the history education at this university through sending history instructors and “re-exporting” new historical methods to China. 5) During the period discussed, there were in total twenty history instructors at this university. Their qualifications were commendable. 6) Regulations concerning history curriculum design, instruction and examination of the university assumed the task of alleviating the political and economic ordeals of China. Nonetheless, as with other reforms in the late Qing era, the government’s reformation efforts in this university could not rescue it from the predicament of “negative repercussions”.
Game Analysis of SME Financing  [PDF]

Journal of Financial Risk Management (JFRM) , 2012, DOI: 10.4236/jfrm.2012.14011
Abstract: The SMEs (small and medium-sized enterprises) play important role in the economy. However, the financing problem is a big difficulty, which has plagued the SMEs’ development. Information asymmetry is the main reason for the SMEs’ gaining funds so hard. The information asymmetry between banks and enterprises is that banks do not know the operating conditions and credit situation of SMEs. Then, to some extent, the banks are reluctant to support credit for businesses under the circumstance of lacking appropriate information, resulting in a “credit crunch” behavior. Therefore, the main measures of solving SMEs’ financing difficulty are to overcome the information asymmetry in the process of SME financing by establishing effective information mechanisms, the credibility and restraint mechanisms, strengthening the construction of credit rating agencies, and promoting the mutual exchange of information.
