Magnetostratigraphic study of Cretaceous depositional succession in the northern Kuqa Depression, Northwest China

Stratigraphic studies on the depositional succession in the Kuqa Depression can be traced back to as early as 1950s[1], however, there are still some disputes about chronostratigraphic division of the Bashenjiqike For- mation because of the paucity of fos…     

A local positive feedback of the tropical Pacific ocean-atmosphere system on interdecadal timescales

SINCE THE 1990S, THE CLIMATIC VARIABILITY ON INTERDE- CADAL TIME SCALES BECAME THE FOCUS OF THE INTERNATIONAL CLIMATOLOGY RESEARCH MISSIONS[1―3]. ON TIME SCALES OF A DECADE OR MORE, THE OCEAN CIRCULATION PREDOMINATEDHEAT BALANCE AND HYDROLOGICAL CYCLE, S…     

Effects of stem structure and cell wall components on bending strength in wheat

Stem is an important organ consisting of storage, transportation and mechanical tissues and is closely related to yield. There is an irregular cavity in the ce- real crop stems and the lower the location, the shorter and thicker the walls of the internode…     

Rapid dendrite growth in quaternary Ni-based alloys

Dendritic growth is one of the most common micro-structural formation mechanisms during crystal growth. Its morphology provides the kinetics information of crystal growth. Therefore, it is valuable to perform the research on rapid dendrite growth in order…     

Using of the surface plasmon resonance cytosensor for real-time and non-invasive monitoring of cellular effects in living C6 cells induced by PMA

By cell and molecular biology, the traditional life science research has been improved into modern ex-perimental science. Because cell is the basic structural and functional unit of the mysterious life, the study of life phenomena will be ultimately embodied into the study of cell biology. How to acquire a dynamic knowledge of the intricate biomolecular reactivity and process in living cells has become one of the hotspots in recent biological researches. For the complexity of cellular effects,…     

Genetic analysis and molecular mapping of a presenescing leaf gene psll in rice （Oryza sativa L.）

A rice psl1 （presenescing leaf） mutant was obtained from a japonica variety Zhonghua 11 via radiation of ^60Co-γ in M2 generation. Every leaf of the mutant began to wither after it reached the biggest length, while the leaves of the wild variety could keep green for 25--35 d. In this study, genetic analysis and gene mapping were carried out for the mutant identified. The SSR marker analysis showed that the mutant was controlled by a single recessive gene （psl1） located on chromosome 2. Fine mapping of the psl1 locus was conducted with 34 new STS markers developed around psl1 anchored region based on the sequence diversity between Nipponbare and 93-11. The psl1 was further mapped between two STS markers, STS2-19 and STS2-26, with genetic distances of 0.43 and 0.11 cM, respectively, while cosegregated with STS2-25. A BAC contig was found to span the psl1 locus, the region being delimited to 48 kb. This result was very useful for cloning of the psl1 gene.     

土木工程词典

本词典非常全面地涉及了土木工程中的各种术语，是公共建设工程史上的一座里程碑。很早，人类就开始想办法驱除自然界中的各种障碍：一根树干被横跨在河的两边，人们就试图改善它的结构，建造桥梁，以便行动更迅速；轮子的发明．不但满足了人类的征服欲，还增加了运输的方便与舒适性；随着人类开始建造木制和石制建筑的需求，出现了钢筋混凝土；工业革命和钢铁工业的迅速发展。铁路的需要和公路网的改进，使高架桥和隧道等大型横跨工程随之产生；

面向方面的数据库系统

数据库系统是当今大多数组织与系统运行的中心。近几年来主要有：面向对象的技术、正在形成的面向方面的软件开发技术集合。这些技术可以提供系统化的手段去管理（例如分布、安全性和持续性这样的横切关心），但是，利用面向对象这样的常规技术不能够模块化。
