MOTIVATION: Lipids are a large and diverse group of biological molecules with roles in membrane formation, energy storage and signaling. Cellular lipidomes may contain tens of thousands of structures, a staggering degree of complexity whose significance is not yet fully understood. High-throughput mass spectrometry-based platforms provide a means to study this complexity, but the interpretation of lipidomic data and its integration with prior knowledge of lipid biology suffers from a lack of appropriate tools to manage the data and extract knowledge from it. RESULTS: To facilitate the description and exploration of lipidomic data and its integration with prior biological knowledge, we have developed a knowledge resource for lipids and their biology-SwissLipids. SwissLipids provides curated knowledge of lipid structures and metabolism which is used to generate an in silico library of feasible lipid structures. These are arranged in a hierarchical classification that links mass spectrometry analytical outputs to all possible lipid structures, metabolic reactions and enzymes. SwissLipids provides a reference namespace for lipidomic data publication, data exploration and hypothesis generation. The current version of SwissLipids includes over 244 000 known and theoretically possible lipid structures, over 800 proteins, and curated links to published knowledge from over 620 peer-reviewed publications. We are continually updating the SwissLipids hierarchy with new lipid categories and new expert curated knowledge. AVAILABILITY: SwissLipids is freely available at http://www.swisslipids.org/. CONTACT: alan.bridge@isb-sib.ch SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

The scope of this study involved the evaluation of the concentration of some volatile organic compounds in the internal environmental air of a naval shipyard in the State of Rio de Janeiro, during painting activities in enclosed, semi-enclosed and open areas. Xylene was the volatile compound found in greatest abundance (25.20 to 191.66 ppm) in the locations researched. Benzene in the air, which is a carcinogenic substance, attained levels of 3.34 ppm in semi-enclosed environments and the highest levels of toluene, xylene and n-butanol were found in the enclosed space of the ship. Results obtained highlight the need to establish air quality control programs in these internal areas, in order to safeguard the health of the workers.

Full title is "A Full and Correct Account of the Chief Naval Occurrences of the Late War Between Great Britain and the United States of America; preceded by a Cursory Examination of the American Accounts of their Naval Actions Fought Previous to that Period: to Which is Added an Appendix; with Plates" This is an expanded version of author William James' pamphlet "An Inquiry into the Merits of the Principal Naval Actions between Great Britain and the United States." (Halifax, Nova Scotia, 1816) In this work he discussed how American ships, during the War of 1812, were larger and more heavily armed and manned than those of the British. He therefore, stated that American victories were due only to their greater numerical force and not their superior seamanship. Naval Occurrences is a thorough documentation of the naval operations from the British perspective that addresses contradictions and inconsistencies within the American official documents as well as political and media accounts. This is perhaps his motivation for the words "Corrected Account" within the title. James' sentiments towards the US most likely sprouted from being held prisoner while visiting in 1812. (He was falsely accused of being a renegade seeking revenge on the US.) In 1813, he escaped to Halifax where he began writing on various naval topics. James became one of the leading authorities on British Naval History.
