Magnesium and its alloys seem to be among the most appealing materials to design biodegradable stents.
Among the solutions proposed to overcome this drawback, the adoption of degradable materials coupled with new shapes of the device seems to be very promising.

According to Science Citation Index Expanded and Social Sciences Citation Index Database in web of science, only 12 records were found in related discipline when “keyphrase extraction” as search title.
The World Wide Web has been widely used by enormous students for acquiring information, learning materials and references.
In order to find reliable and trustworthy materials, students must sift through the millions of pages available on the web, thus Kilbride J and Mangina E. (2005) describe a system designed to assist students of a web-based learning environment to achieve either acting autonomously or assisting users to create queries.
