Science 2.0 Gains Another Search Engine: Q-Sensei From Lalisio

.: Barbara Quint reports in the 21 August 2008 InfoToday about another new search engine that has joined the ranks of other like Scirus and Google Scholar, to be used for searching topics in science and technology. Excerpt from her article:

Another sci-tech search engine has joined others to serve the needs and tastes of scientists. This one comes from a small company whose main service is the Lalisio social network for scientists. While the 2 million-plus article content nowhere near reaches the size and scope of behemoths such as Elsevier’s Scirus or Google Scholar, the Q-Sensei search engine (http://literature.lalisio.com/oai.html) has a metadata orientation that offers some interesting search capabilities. It can suggest alternative search strategies and allows searchers to narrow and focus their search results in a manner familiar to traditional searchers. At this point, it only searches open access content from ArXiv and PubMed Central, but parallel services also reach IngentaConnect and a series of book citation sources.

The arXiv database focuses on papers in physics, mathematics, nonlinear science, computer science, quantitative biology, and statistics. PubMed Central, from the National Library of Medicine, archives biomedical and life science journals. Under recent regulations, NIH-funded research must emerge—in time—into open access on PubMed Central. The National Institutes of Health are among the largest funders of medical research worldwide. In handling PubMed Central content, Lalisio uses MeSH thesaurus headings.

In addition to suggesting search strategies and terms, Q-Sensei lets users search within the search suggestions. It structures searches within categories, e.g., author, keyword, publisher, language, and year of publication. Users can remove search suggestions as well as adding them to focus search results. The service analyzes search results into different metadata categories, such as author, keyword, or document type, and displays terms in these categories that appear most often.

ICIS Chemical Business Updates Its August 2006 Bulk Chemical Prices

.: Good news to those of us who need access to current bulk chemical prices. Simon Robinson of ICIS Chemical Business in London confirmed in an e-mail today that 62 of the chemical prices on the 26 August 2006 list of indicative chemical prices, which was the last full list of bulk chemical prices published by ICIS in the final issue of Chemical Market Reporter, have been updated to reflect 2008 prices. Simon writes:

...we have managed to give updated prices on 62 materials in the list, which is effectively all of the prices that we cover in that list now. Our portfolio of pricing information is rather more focused on the petrochemicals sector than the fine and specialty businesses, especially since the merger of ICIS Chemical Business Americas and Europe into a single publication.

One of the features of the new list is that several prices are quoted over quite wide ranges. This is because there have been considerable variations in the price of a number of oil-based commodities. It might add a little verisimilitude to your students’ projections of profitability to see if they can find the minimum price at which their processes are profitable.
