Construction of the Online Course “Automotive Engine Structure and Principles” under the Background of Building a First Class Undergraduate Program

Guided by the concept of “first-class undergraduate education” and centered on “students”, the original teaching curriculum system, course introduction, teaching outline, teaching plan, teaching contents, multimedia courseware and other teaching resources of “Automotive Engine Structure and Principles” course are optimized and reconstructed in this paper. At the same time, due to the limited teaching hours and resources of offline course, all of the optimized and restructured electronic resources of this course and teaching videos will be upload to the network platform to establish high-quality online course, so that students can review the course to learn the key and difficult knowledge points contrapuntally at anytime and anywhere

Online Cataloging Tools versus Print Cataloging Tools

In the Bibliographic Services Department of The University of Southern Mississippi’s Libraries, the department not only maintains up-to-date print cataloging tools, but also subscribes to most of the online cataloging tools. The five catalogers in our department have different preferences in choosing the online or print versions when cataloging: one uses only print, one uses only online when possible, and the rest use both as needed. It appears that migrating totally from the print to online cataloging tools is not a preferred process for many of our catalogers, even though the benefits of using the online tools are substantial in saving time, accuracy, and uniformity. The authors’ experience with colleagues raised questions about what prompts some catalogers to prefer online to print and vice versa at libraries in the southeast region of the United States

Interplay between Quantum Size Effect and Strain Effect on Growth of Nanoscale Metal Thin Film

We develop a theoretical framework to investigate the interplay between quantum size effect (QSE) and strain effect on the stability of metal nanofilms. The QSE and strain effect are shown to be coupled through the concept of "quantum electronic stress. First-principles calculations reveal large quantum oscillations in the surface stress of metal nanofilms as a function of film thickness. This adds extrinsically additional strain-coupled quantum oscillations to surface energy of strained metal nanofilms. Our theory enables a quantitative estimation of the amount of strain in experimental samples, and suggests strain be an important factor contributing to the discrepancies between the existing theories and experiments
