Effects of Mooring-Design Parameters and Layout Configuration on the Dynamic Responses of Modular Floating Structures

open access: yes한국해양공학회지
Mooring systems for modular floating structures (MFSs) in shallow water require designs that account for a limited water depth, restricted footprint, and coupled responses among floaters, connectors, and mooring lines.

Tap Water vs. Bottled Water in a Footprint Integrated Approach [PDF]

open access: yes, 2009
A Footprint Integrated approach was used to assess and compare the impact on the environment and on the resources of tap water (TW) and pet-bottled natural mineral water (BW). A set of BW from six Italian companies was analyzed. This set covers about the

High‐Temperature Phase Transformation in a V‐9Si‐6.5B Alloy: The Kinetic and Crystallographic Pathway From V5SiB2 to V8SiB4

open access: yesAdvanced Engineering Materials, EarlyView.
In situ synchrotron high‐energy X‐ray diffraction reveals the real‐time high‐temperature phase evolution of a ternary V‐9Si‐6.5B alloy. The study uncovers a kinetically delayed V5SiB2 → V8SiB4 transformation governed by massive structural and chemical barriers.
