微悬浮体预处理在活性染料冷轧堆染色中的应用

本文介绍了微悬浮体预处理工艺在活性染料冷轧堆染色中的应用.将经过预处理的纯棉织物与传统前处理的纯棉织物在相同染色条件下染色,与采用传统工艺所得染品相比,采用新工艺所得染品有明显的色泽增深效果,经济效益明显.采用新工艺染色可降低生产废水中的废弃染料量,可减轻环境污染,社会效益可观.     

"以人为本"之"人"的科学内涵探析

科学发展观的核心是以人为本。“以人为本”之“人”不是专指或特指一些行业或部门中的某些人或某类人,更不是指那些损公肥私、损人利己谋取不当利益的人,而是指创造历史、推动历史发展的人民群众。厘清并把握“以人为本”之“人”的科学内涵,是准确领会科学发展观的精神实质,是贯彻落实科学发展观的前提条件。     

Proteome changes in the plasma of Papilio xuthus (Lepidoptera: Papilionidae): effect of parasitization by the endoparasitic wasp Pteromalus puparum (Hymenoptera: Pteromalidae)

Although the biochemical dissection of parasitoid-host interactions is becoming well characterized, the molecular knowledge concerning them is minimal. In order to understand the molecular bases of the host immune response to parasitoid attack, we explored the response of Papilio xuthus parasitized by the endoparasitic wasp Pteromalus puparum using proteomic approach. By examining the differential expression of plasma proteins in the parasitized and unparasitized host pupae by two-dimensional (2D) electrophoresis, 16 proteins were found to vary in relation to parasitization compared with unparasitized control samples. All of them were submitted to identification by mass spectrometry coupled with a database search. The modulated proteins were found to fall into the following functional groups: humoral or cellular immunity, detoxification, energy metabolism, and others. This study contributes insights into the molecular mechanism of the relationships between parasitoids and their host insects.

科学发展观视域下的经济法探微

科学发展观是崭新的哲学理论，经济法是现代法律制度，虽然不在同一层次上，但是科学发展观与经济法具有一定的内在联系。科学发展观对经济法的立法、实施具有重要的指导意义，而经济法是实现科学发展观的主要制度性方法：

In-situ cosmogenic 36Cl denudation rates of carbonates in Guizhou karst area

This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic36Cl in China. Concentrations of natural Cl and in-situ cosmogenic36Cl in bare carbonates from Guizhou karst areas were measured with isotope dilution by accelerator mass spectrometer. The Cl concentration varied from 16 to 206 ppm. The 36Cl concentrations were in range of (0.8-2.4)106 atom g-1 , resulting in total denudation rates of 20-50 mm ka-1 that averaged over a 104-105 a timescale. The 36Cl-denudation rates showed roughly a negative correlation with the local mean temperature. This preliminary observation may suggest the variations of proportions of chemical weathering and physical erosion in denudation process, depending upon local climatic conditions.
