Informatization is one of the most important city development strategies when Beijing oriented toward the 21st century and the information society. The purpose of the informatization is to spur industrialization and modernization through informatization, while developing the capital economy with knowledge economy as its main content, and strengthening the competitiveness of the city and improvi...

The aim of this paper is to showcase recent developments in the UK arts and humanities e-Science initiative. A specific grass-roots research agenda in arts and humanities e-Science has been developing over the past few years in the UK. In this paper, we will look at the new research questions and institutions emerging in the many e-Science grass-roots activities.

Acyl carrier protein (ACP) is a small (9kDa) protein which is essential for fatty acid synthesis. In bacteria [ l ] and plants [2] which use type I1 dissociable fatty acid synthetases, acyl chains are esterified to ACP through the 4'-phosphopantetheine prosthetic group, and ACP acts as a carrier during fatty acid synthesis. ACPs from bacteria and plants are very similar. All are small acidic pr...

Effective population size (N(e)) is the key parameter for predicting genetic drift associated with germplasm regeneration. A major factor reducing N(e) below the census population size (N(c)) is variation in seed production among plants in a given population. The objectives of this study were to estimate N(e)/N(c) associated with variation in seed production in three model wind pollinated, pere...

This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...

Soil and plant hydraulics constrain ecosystem productivity by setting physical limits to water transport and hence carbon uptake by leaves. While more negative xylem water potentials provide a larger driving force for water transport, they also cause cavitation that limits hydraulic conductivity. An optimum balance between driving force and cavitation occurs at intermediate water potentials, th...

Human activities have continuously increased the level of heavy metal ions circulating in the environment. It is important to understand the tolerance of plant species to high concentrations of heavy metals. Very little is known on the response of Eucalyptus species to Zn and Cu toxic concentrations Eucalyptus camaldulensis, E. microtheca, and E. occidentalis seeds were grown in silt and irriga...

The objective of this study was to evaluate the dynamics of tocopherols in cotyledons and radicles from sunflower seeds with high and low total tocopherol content, mainly in the α-tocopherol form, and from seeds with increased proportions of β-, γ-, and δ-tocopherol, both under dark and light conditions. Tocopherol content was measured every 24 h from 1 to 12 days after sowing. In all cases, th...
