On the Interaction of Cohesive Field [PDF]
Progress of Theoretical Physics, 1951 To avoid the divergence difficulties of selfenergies, new field playing the role of cohesive force has been introduced by Pais!) and Sakata2). These theories gave approximately correct answers for the mass defect of the proton compared with neutron. But the mass of the cohesive field thus introduced is to be assumed about 100 times electron mass in ...

Advanced Engineering Materials, EarlyView.This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...

W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications
Advanced Engineering Materials, EarlyView.This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...

European „C” quest: community, competitiveness, convergence, cohesion. what should the “eu new comer romanians” aim for? [PDF]
Annals of the University of Oradea: Economic Science, 2008 The analyses carried out both at the centre (Brussels) and at the destination (member states) (ab)use of the principle that in public expenditure terms “spent money means well-spent money” and consider that absorption capacity equals economic performance

兩篇七年級「能量塔」文本之比較分析 Evaluating Two 7th Grade Texts of “Pyramid of Energy Flow”
Journal of Research in Education Sciences, 2011 本文旨在分析比較2 篇能量塔文本的語言特性及其差異。選取七年級X、Y版生態系單元與能量塔概念有關的內容為標的文本，以逐步文本分析系統分析比較2 篇文本的基本語言、漢語及科學語言等特性之差異。研究發現，2 篇文本的詞彙密度及科學詞彙密度未達顯著差異，而科學詞彙內容則有不同。從漢語特性來看，X版出現無訊息零代詞及不具分類意涵之含「的」的名詞組較Y 版多，可能會對閱讀X 版之讀者有較多閱讀理解之挑戰。從科學語言特性來看，Y版以具體事件逐漸抽象化的歷程來構作科學概念，符合技術建構歷程，並使用較多元的銜接關係 ...

Advanced Engineering Materials, EarlyView.Highly textured CeO2 nanowires and nanoporous thin films are successfully synthesized by water dissolution of Sr3Al2O6 (SAO) from the SAO:CeO2 vertically aligned nanocomposites (VANs). The morphology of CeO2 can be varied by VAN composition. It demonstrates a new method for synthesizing nanostructured CeO2 without chemical etching or complex micro ...
