FengShui – a systematic research of vernacular sustainable development In Ancient China and its lessons for future

Creating and keeping balance is the basic and the most important principle of Chinese traditional philosophy. It provides the fundamental philosophical basis for Chinese FengShui in pursuing coexistence between human and nature. Influenced by the traditional philosophy, Chinese FengShui displays the concept of balance, harmony and order in the design of ancient living environment and development of traditional settlement with many detailed manifestations that embody representative sustainable character. This paper discusses the principle of sustainability in FengShui practice from philosophical, environmental, ecological, socio-cultural and economic perspectives. It further intends to reveal the inherent connection between FengShui, traditional Chinese culture and the vernacular sustainable development of the agricultural society in ancient China

Modern interpretation of FengShui in contemporary sustainable residential design

The FengShui practice, through its core philosophy, has for centuries embraced sustainability in the design of traditional living environments and natural settlements in China. There are many encounters of sustainable FengShui manifestations in the ancient Chinese settlements, some of which have been studied in this research and interpreted from the theoretical, environmental, ecological, socio-cultural and economic perspectives. Based on the research findings and their contemporary interpretation, the link between the research and practice has been formed via undertaking the residential development design study on location in Shanghai. The results of the study thus far are reported in this paper in terms of their urban and design resolution, focusing on the pursuance of the balance between three main aspects – energy, environment and ecology. The unification between circulation of Qi and environmental elements is reflected in its modern context and represented in terms of master planning on the macro scale and consideration of shelter environmental qualities on the micro scale

The Glashow resonance as a discriminator of UHE cosmic neutrinos originating from p-gamma and p-p collisions

We re-examine the interesting possibility of utilizing the Glashow resonance (GR) channel nu_ebar + e^- to W^- to anything to discriminate between the UHE cosmic neutrinos originating from p-gamma and pp collisions in an optically thin source of cosmic rays. We propose a general parametrization of the initial neutrino flavor composition by allowing the ratios Phi^{p gamma}_{pi^-}/Phi^{p gamma}_{pi^+} and Phi^{pp}_{pi^-}/Phi^{pp}_{pi^+} to slightly deviate from their conventional values. A relationship between the typical source parameter kappa = (Phi^{p gamma}_{pi^+} + Phi^{p gamma}_{pi^-})/(Phi^{pp}_{pi^+} + Phi^{pp}_{pi^-} + Phi^{p gamma}_{pi^+} + Phi^{p gamma}_{pi^-}) and the working observable of the GR R_0 = Phi^T_{nu_ebar}/ (Phi^T_{nu_mu} + Phi^T_{nu_mu}) at a neutrino telescope is derived, and the numerical dependence of R_0 on kappa is illustrated by taking account of the latest experimental data on three neutrino mixing angles. It is shown that a measurement of R_0 is in principle possible to identify the pure p-gamma interaction (kappa =1), the pure pp interaction (kappa =0) or a mixture of both of them (0 < kappa < 1) at a given source of UHE cosmic neutrinos. The event rate of the GR signal against the background is also estimated.Comment: 13 pages, 6 figures, final version to appear in Phys. Rev.

High purity tetrahedral nanocrystals of CoO, with edge lengths of 4.4±0.2 nm, were synthesized and separated from Co nanocrystals, using a novel magnetic field phase-selection technique. Self-assembling of the faceted CoO nanocrystals forms ordered superlattices, the structures of which are determined

On the momentum-dependence of K−K^{-}-nuclear potentials

The momentum dependent $K^{-}$-nucleus optical potentials are obtained based on the relativistic mean-field theory. By considering the quarks coordinates of $K^-$ meson, we introduced a momentum-dependent "form factor" to modify the coupling vertexes. The parameters in the form factors are determined by fitting the experimental $K^{-}$-nucleus scattering data. It is found that the real part of the optical potentials decrease with increasing $K^-$ momenta, however the imaginary potentials increase at first with increasing momenta up to $P_k=450\sim 550$ MeV and then decrease. By comparing the calculated $K^-$ mean free paths with those from $K^-n$/$K^-p$ scattering data, we suggested that the real potential depth is $V_0\sim 80$ MeV, and the imaginary potential parameter is $W_0\sim 65$ MeV.Comment: 9 pages, 4 figure
