PowerMV Molecular Viewer PowerMV: A software environment for statistical analysis, molecular viewing, descriptor generation, and similarity search. Jack Liu, Jun Feng, Atina Brooks and Stan Young National Institute of Statistical Sciences Basic Functions: • Supports MDL SDF format • Displays molecules in multiple columns. • Displays properties contained in SD file in a table. • Anti-alias technology for best picture quality. • Table of molecule pictures and properties can be exported to Excel (Office XP and above) to generate personalized reports. • Calculates three types of binary atom pair descriptors and continuous weighed burden numbers.
Images from the History of Medicine (IHM) Images from the History of Medicine (IHM) provides access to over 70,000 images in the collections of the History of Medicine Division (HMD) of the U.S National Library of Medicine (NLM). The collection includes portraits, photographs, caricatures, genre scenes, posters, and graphic art illustrating the social and historical aspects of medicine dated from the 15th to 21st century. The records from the Images from the History of Medicine database are also searchable in LocatorPlus. This database assists users in finding and viewing visual material for private study, scholarship, and research. This site contains some materials that may be protected by United States or foreign copyright laws.
Chemistry Freeware On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet. All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications. Unless otherwise noted, the programs are for Windows systems. PubChem Download Page This file contains the structures downloaded from the PubChem FTP site that have at least one assay result associated with them that was obtained in the context of the NIH Common Fund (previously: NIH Roadmap) Molecular Libraries Probe Production Centers Network (previously: Molecular Libraries Screening Center Network), part of the Common Fund’s Molecular Libraries and Imaging program . It is organized by unique chemical structures (“Compounds” in PubChem parlance), i.e. assay results for possibly multiple different samples (“Substances” in PubChem parlance) have been combined into the one record representing the unique chemical structure. Placeholder assays (assays containing a single record only) have been filtered out. Explanation of the property data fields in the SD file (note - properties present in the original PubChem files have been copied unchanged, for the explanation of those properties we point directly to the appropriate PubChem document ):
Find an Intentional Community - Communities Directory - Search The Intentional Communities Directory is part of the Intentional Communities website, a project of the Fellowship for Intentional Community (FIC). Intentional Communities can update their listings online so you get the most up to date information possible. You can add your community now. If you are looking for an intentional community, ecovillage, cohousing, commune, co-op, or other cooperative living arrangement, browse through our community lists – geographic, or by type of community (ecovillages, communes, cohousing, co-ops, or christian), look at our maps, or search our database.
Chemistry Labs Atomic Structure Series - Classifying Matter - Great Helpers View Now... Application of the Scientific Method - Apply Each Step - Form Experiments Chemical Library Enumeration Chemical Library Enumeration (This workflow can be found on the KNIME Workflow Public Server under 050_Applications/050001_ChemicalLibraryEnumeration Note that this workflow requires the installation of various nodes from the community update site!) The Workflow The workflow demonstrates how a chemist could create a virtual library of Amides based on a set of Acids and Amines.For the enumerated products, some molecular properties are then calculated and the products are filtered based on the Lipinski "rule of 5". In order to demonstrate the interoperability of the different community contributions, the workflow uses nodes from the RDKit, CDK, and Indigo integration.
Chemistry Demonstrations, Experiments, Labs & Projects These are tutorials for performing your own chemistry demonstrations, laboratory exercises, projects, and chemistry experiments. Photos and movies are available for some chemistry demos. Chemistry Laboratory Safety RulesMake your chemistry laboratory experience safe by following these simple rules. How to Write a Lab ReportLab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report, use that. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report.
