New trends In urban and regional governance in the Pearl River Region

Parallel Session 3: 3.1 UrbanizationThe impacts of globalization and the collapse of the global credit market, along with the shift in economic production, forced economic restructurings, are greatly affecting and stimulating the trajectories of China's economic developments. Under these circumstances, urban and regional governance is changing rapidly with complicated relations between government, the economy and the emerging civil society. The Outline of the Plan for the Reform and Development of the PRD 2008-2020 and other national plans for revitalizing key industries provide impetus for possible mid-term regional economic development and transformation in south China.published_or_final_versio

Analysis of stray current induced by cathodic protection on steel-framed masonry structures

Cathodic protection (CP) has been successfully employed to protect steel-framed masonry buildings from corrosion related damage. When a CP system is installed to protect the structural members, other metallic items which are within the fabric of the structure but are not in direct electrical continuity may suffer from stray current interactions, resulting in accelerated corrosion of the discontinuous items. Therefore, these must be considered when CP systems are designed prior to installation. This paper presents both experimental and numerical studies into the risk and extent of stray current corrosion in steel-framed masonry structures when subject to impressed current cathodic protection. The objective is to allow CP systems to be optimised so that interference is minimised without compromising the technical or cost benefits of this method of corrosion control

1-D modelling and 3-D simulation of confined bubble formation and formation and pressure fluctuations during flow boiling in a microchannel with a rectangular cross-section of high aspect ratio

Copyright @ 2009 ASMEA simple 1-D model with low requirements for computing time is required to investigate parametric influences on the potentially adverse effects of pressure fluctuations driven by confined vapour bubble growth in microchannel evaporative cooling systems operating at high heat fluxes. A model is developed in this paper for the particular conditions of a channel of rectangular cross-section with high aspect ratio with a constant inlet flow rate (zero upstream compressibility). (The model will later be extended to the conditions of finite upstream compressibility that lead to transient flow reversal). Some parametric trends predicted by the model are presented. The simplifying assumptions in the model are examined in the light of a 3-D simulation by a commercial CFD code, described in an accompanying paper by the same authors. The predictions of pressure changes are in reasonable agreement. It is suggested that the 1-D model will be a useful design tool.This work is supported by the UK Engineering and Physical Sciences Research Council (EPSRC) under grants EP/D500095/1 and EP/D500125/1

TGF-β signaling links E-cadherin loss to suppression of nucleotide excision repair.

E-cadherin is a cell adhesion molecule best known for its function in suppressing tumor progression and metastasis. Here we show that E-cadherin promotes nucleotide excision repair through positively regulating the expression of xeroderma pigmentosum complementation group C (XPC) and DNA damage-binding protein 1 (DDB1). Loss of E-cadherin activates the E2F4 and p130/107 transcription repressor complexes to suppress the transcription of both XPC and DDB1 through activating the transforming growth factor-β (TGF-β) pathway. Adding XPC or DDB1, or inhibiting the TGF-β pathway, increases the repair of ultraviolet (UV)-induced DNA damage in E-cadherin-inhibited cells. In the mouse skin and skin tumors, UVB radiation downregulates E-cadherin. In sun-associated premalignant and malignant skin neoplasia, E-cadherin is downregulated in association with reduced XPC and DDB1 levels. These findings demonstrate a crucial role of E-cadherin in efficient DNA repair of UV-induced DNA damage, identify a new link between epithelial adhesion and DNA repair and suggest a mechanistic link of early E-cadherin loss in tumor initiation

New neighborhood based rough sets

Neighborhood based rough sets are important generalizations of the classical rough sets of Pawlak, as neighborhood operators generalize equivalence classes. In this article, we introduce nine neighborhood based operators and we study the partial order relations between twenty-two different neighborhood operators obtained from one covering. Seven neighborhood operators result in new rough set approximation operators. We study how these operators are related to the other fifteen neighborhood based approximation operators in terms of partial order relations, as well as to seven non-neighborhood-based rough set approximation operators

Using anomalous data to foster conceptual change in security awareness

Users are often regarded as the weakest link in an information system. To this, information security awareness nowadays gains much attention in organizations, schools, and universities. Since the practice of safe computing involves individual perception, effective pedagogy that can deliver a proper message about security awareness is vital for information security education. This article reports an experiment conducted on 102 university students which determined if anomalous data can provoke conceptual change, and whether anomaly can affect the perception of information security of the students. With evidences found from the experiment, it is concluded that conceptual change fostered by anomalous data is an effective pedagogy for information security education. ©2009 IEEE.published_or_final_versionThe IEEE International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS 2009), Kanazawa, Japan, 7-9 January 2009.
