Consolidation behavior of cement- and lime/cement-mixed column foundations

The consolidation behavior of mixed in place cement- and lime/cement-mixed column was studied. Consolidation of the composite foundation was modeled as a three-dimensional axi-symmetric problem. The authors used the finite difference method to obtain the pore pressure variation with time at any location below the surface. A computer program developed by the authors was used to draw some interesting conclusions about the consolidation behaviors of cement- and lime/cement-mixed pile foundation. Finally, a combined model including the permeability coefficients of cement-mixed piles and soil, was studied and its feasibility was evaluated.

On“The Five-Step Method”in Teaching Junior English for China

Junior English for China' is based on the 'Five-Step' teaching method: Revision, Presentation, Drilling, Practice, Consolidation. Each step has its own particular methodology and requires the teacher to adopt a certain role. This paper is a discussion of the "Five-Step Method".     

Consolidation and protection by nanolime: Recent advances for the conservation of the graffiti,Carceri dello Steri Palermo and of the 18th century lunettes,SS. Giuda e Simone Cloister,Corniola (Empoli)

Nanolime dispersed in 2-propanol was extensively used for the consolidation of wall paintings. The knowledge of the advances of this methodology dealing with all the possible effects associated with the nanolime new material in conservation is fundamental to assess and improve the technique. In this paper, four different dispersions of Ca(OH)₂ nanoparticles were characterised by Small Angle X-rays Scattering technique (SAXS) and Transmission Electron Microscopy (TEM) in order to achieve information on size, shape, polydispersity, agglomeration, and crystal structure (by SAED patterns) of the particles. Once characterised, the dispersions were tested in two different case studies, the Carceri dello Steri in Palermo with their graffiti and the 18th century lunettes at the SS. Giuda e Simone Cloister, Corniola (Empoli) with their lime-based mural paintings. The treated samples were characterised in relationship to either their morphology and surface chemical composition by Scanning Electron Microscopy coupled with Energy Dispersive X-rays spectroscopy (SEM-EDX), or their water absorption and mechanical properties (resistance to material abrasion). The results obtained showed that all the dispersions were nanometrically structured and their application succeeded in recovering the mechanical properties of the painting or graffito layers, not altering their permeability to water and keeping perfectly the wall transpiration. However, the dispersions constituted of the nanoparticles obtained via a synthesis able to control size and shape of the Ca(OH)₂ particles resulted in a better performance in situ, even if the differences found by SAXS and TEM were slight.     

Abstraction and consolidation of the limit procept by means of instrumented schemes: the complementary role of three different frameworks

I investigate the contributions of three theoretical frameworks to a research process and the complementary role played by each. First, I describe the essence of each theory and then follow the analysis of their specific influence on the research process. The research process is on the conceptualization of the notion of limit by means of the discrete continuous interplay. I investigate the influence of the different perspectives on the research process and realize that the different theoretical approaches intertwine. Moreover, I realize that the research study demanded the contribution of more than one theoretical approach to the research process and that the differences between the frameworks could serve as a basis for complementarities.

检察一体化的价值定位

检察权是法律监督权。检察机关(或检察官)是检察权的载体所在,它以法律监督机关的形式呈现出来。检察一体化是检察机关行使检察权工作的表现形式。对检察权、检察机关与检察一体化的探讨均须立足于既有法律秩序进行阐述才更有现实意义。     

The Rise of the Small: The Effects of Industry Consolidation on Small Legal Publishers

Summary

The legal publishing industry has experienced waves of acquisition and consolidation, with almost all of the established players becoming affiliated with either Thomson or Reed Elsevier. A widespread assumption is that this consolidation is driving out the smaller participants in the market, especially in conjunction with the expansion of free Web sites for primary source material. It is presumed that the entrepreneurs who have smaller, profit-based companies are becoming less interested in the market due to financial pressures, increased difficulty of capturing market share, and threat of acquisition (friendly or hostile).

In order to confirm or refute this assumption, the author reviews the industry consolidations, describes the delineation of representative small legal publishers, and analyzes their responses to questions about how the recent industry changes have affected their strategies, markets and product lines. The resulting picture is of an environment much different than that painted by current media pundits. Contrary to the presumption of a disappearing landscape of small players, there is a positive perception of “ripe opportunity” pushing companies into this marketplace-companies armed with new technology tools and strong convictions that they can reach customers ready and willing to do old business in new ways. The small publishers seem to be weathering the climactic industry changes, and have expectations of growth and expansion.
