Our aim is to defend the Precautionary Principle (PP) against main theoretical and practical criticisms that it has raised by proposing a novel conception specific formulation of principle. We first address concerns idea there being principle precaution arguing for distinctively political PP as opposed moral one. claim rationale grounded in fact contemporary societies wish avoid morally unaccep...

This is part two of our study on the spreading properties Lotka-Volterra competition-diffusion systems with a stable coexistence state. We focus case when initial data are exponential decaying. By establishing comparison principle for Hamilton-Jacobi equations, we able to apply approach Fisher-KPP equation due Freidlin, Evans and Souganidis. As result, exact formulas speeds their dependence der...

Abstract To improve the quality of fiber optic wire wrapping, influence each parameter wrapping on stress distribution is studied, and mechanical properties are simulated based principle fine mechanics composite materials. Solid elements used for modeling through finite element analysis, problem using ANSYS to solve package initially solved by establishing a 1° model analysis calculation. The r...

Kyoto is a miniature of Japan; through centuries of experience and persistence, it has maintained the symbols of the country’s civil and cultural identity. The city has demonstrated a collection of Japan’s noble identity and characteristics through its material and spiritual heritage. Kyoto’s rich history and its position have gathered a collection of religion-based works, artistic innovations,...
