ScienceIndex.com is a Web 2.0 sciences social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Engineering Sciences, the site has now included the two new categories Industrial Engineering and Mechanical Engineering. While the Industrial Engineering category covers the design, improvement, and installation of integrated systems of people, materials, and equipment, the Mechanical Engineering category covers design, production, and use of machines and tools for generation and application of heat and mechanical power.
ScienceIndex.com’s Engineering Sciences Category covers the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems. Its eight subsections include Architecture, Chemical Engineering, Civil Engineering, Communication, Control Systems, Electronics, Industrial Engineering and Mechanical Engineering. Users can receive alerts if new content has been posted in this category by subscribing to ScienceIndex.com’s Engineering Sciences RSS feed.
ScienceIndex.com’s Industrial Engineering Sciences category covers the design, improvement, and installation of integrated systems of people, materials, and equipment. It currently contains 12,200 articles partly derived from nearly 100 scientific journals. The latest articles in this category are also available through a Industrial Engineering Sciences RSS feed. One of the latest additions covers use of geosynthetics to improve seismic performance of earth structures. The authors review seismic performance of earth structures based on case histories in Japan, demonstrate advantages of using geosynthetics in improving their seismic performance and highlight geosynthetic-reinforced soil retaining walls. They also introduce further applications of the reinforcement method using geosynthetics including application to bridge abutments and piers and application to ballasted railway tracks. Another recently published article in this category assesses laboratory sample preparation for fiber-reinforced sands. The authors investigate a new fabrication procedure for fiber reinforced samples using vibration of moist sand/fiber mixtures and assess its effects on the fiber orientations.
ScienceIndex.com’s Mechanical Engineering Sciences category covers design, production, and use of machines and tools for generation and application of heat and mechanical power. It currently contains nearly 13,000 articles partly derived from almost 60 scientific journals. The latest articles in this category are also available through a Mechanical Engineering Sciences RSS feed. One recently included article in this category presents effects of surface residual stress and surface elasticity on the overall yield surfaces of nanoporous materials with cylindrical nanovoids. The authors demonstrate that surface stress has a significant influence on the yielding of these materials with voids of radii smaller than 50 nm. Their results show that the effect of the surface residual stress is much more important than the surface elasticity effect, and that surface residual stress should be considered in estimating the yield strength of nano-heterogeneous materials. Another recently published article presents a novel mechanical bioreactor for concomitant fluid shear stress and substrate strain. This study presents the design of a multimodal loading device which can apply substrate stretch and fluid flow simultaneously while allowing for real-time cell imaging.
ScienceIndex.com currently contains over 1.44 million stories distributed among 75 categories. 75,777 users monitor nearly 8,400 journals covering the broad spectrum of sciences. They share circa 2,500 new articles every day. Since new science content is discovered in real-time, the delay between original publication and appearance at ScienceIndex.com is no more than two days. ScienceIndex.com provides an advanced search feature which suggests up to ten closely related articles for a search and also for a selected story. Other features include a “Life Traffic Feed”, a “Top Content” sidebar, Google Translate functionality, and RSS feeds for every category. ScienceIndex.com also maintains the new Twitter account @ScienceIndex_.
