Three new asymmetric photochromic diarylethenes bearing fluorine atoms at the ortho-, meta-, or para-position of one terminal phenyl group were synthesized, and their photochromism and kinetics of the photochromic cyclization/cycloreversion both in different solvents and in PMMA films were...

Construction of theme park has been launched since the early 1990s in Chengdu City, but ended up as a losing proposition after its short-term prosperity because of similar scale and theme with those in other cities. As more international well-known theme parks enter the market, theme parks in...

This paper makes a brief description of the definition and methods of data mining. It describes the characteristics of agricultural data (value delivery, specialization, spatio-temporal bidimensionality) and the status of application of data mining technology in agriculture.

This paper presents a new approach to modeling of heat transfer by ground heat exchangers, involving unsteady heat conduction in composite media together with complex geometry. Analytical solutions for continuous line and cylindrical-surface sources are developed based on Jaeger’s...

In this study we assess the impact of increased foreign competition on labour markets and income distribution in Canada, using a newly developed dynamic microsimulation computable general equilibrium (CGE) model. The main findings of the simulations conducted are that the decline in world prices...

Since Canada is a very open economy, globalisation and increased foreign competition may entail significant long-run labour market and distributional implications. Indeed, with increased foreign competition and China’s accession to the World Trade Organisation (WTO) in 2001, Canada is facing...

Based on practice of the land consolidation planning in Changfeng County of Hefei City, taking full account of reality of land consolidation and its significance as livelihood project, we analyzed map compilation procedure. In combination with actual effect of land consolidation, we carried out...

In this paper, an N-coupled nonlinear Schrödinger system in optical fibers with energy-exchanging and different self-phase modulation and cross-phase modulation terms is investigated. The system is found to be integrable in the sense of passing the Painlevé analysis. The Lax pair for the...

Heat transfer by borehole ground heat exchangers involves diverse time–space scales and thus imposes a significant challenge to geothermal engineers. In order to overcome this challenge, this paper develops an analytical full-scale model from the idea of matched asymptotic expansion. The...
