http://www.amser.org/SPT--Home.php AMSER (the Applied Math and Science Education Repository) provides educational resources and services built specifically for use by those in Community and Technical Colleges but free for anyone to use. http://amser.org//SPTUI--CWIS/images/cwis_logo.gif http://amser.org//SPTUI--CWIS/images/cwis_logo.gif 69 21 AMSER Logo en-us ealmasy@scout.wisc.edu ealmasy@scout.wisc.edu Thu, 28 Aug 2008 00:00:00 -0500 Wed, 27 Aug 2008 00:00:00 -0500 http://backend.userland.com/rss092 http://www.amser.org//SPT--FullRecord.php?ResourceId=7084 In this Web site, courtesy of Dr. Thurston Lacalli of the University of Saskatchewan, visitors will find an excellent collection of marine invertebrate larvae images. Consisting mainly of transmission electron micrographs, the image gallery may be accessed through a graphical or text-only menu. The phylogenetic tree layout of the graphical menu helps familiarize visitors with invertebrate classification. Lacalli also provides a brief tutorial intended for students new to the topic, which addresses basic features of marine invertebrate larvae and their phylogenetic significance. The sections on protostomes and deuterstomes include loads of helpful diagrams. Altogether, this visually appealing site would be a welcome addition to college-level courses in zoology or related subjects. 2008-08-28 03:00:04 http://www.amser.org//SPT--FullRecord.php?ResourceId=7524 The Agency for Toxic Substances and Disease Registry (ATSDR) is continually assembling toxicological profiles for hazardous substances. This site contains 256 online profiles listed alphabetically by chemical name. Each profile begins with a non-technical public health statement discussing the chemical, its environmental and health effects, and risk of human exposure. A more technical version of this information can also be downloaded in Adobe Acrobat (.pdf) format. 2008-08-28 03:00:04 http://www.amser.org//SPT--FullRecord.php?ResourceId=7529 The US Department of Agriculture's Plants Database is continually adding improvements. Most recently, the Web site has added an advanced query to allow users to search for specific plant data based on many different search characteristics. This new feature is also user friendly; by clicking on any of the fields, a definition of the field is displayed. Also new are targeted links that allow you to link directly from a queried plant profile to other Web sites with information on that plant. Links to county-level maps have also been included for a few states. 2008-08-28 03:00:04 http://www.amser.org//SPT--FullRecord.php?ResourceId=4698 Massachusetts Institute of Technology Professors Darrell Irvine and Nicola Marzari present this introductory course, which focuses on the "fundamentals of structure, energetics, and bonding that underpin materials science." Designed for undergraduate students, topics here include: thermodynamic functions, electronic bonding, stability, and magnetism of materials. Visitors are able to download all lecture notes, assignments, and exams from this course as PDF files, and the "Readings" section presents a helpful bibliography. In the "Recitations" section, users will find all the practice problems and solutions in structure bonding and thermodynamics used in the course. This is a useful resource for educators as it contains ready-made assignments and exams in materials science and technology from a respected institution that can bolster any syllabus. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7055 The Dolan DNA Learning Center of Cold Spring Harbor Laboratory invites visitors to explore their new online feature -- Our Neanderthal Reconstruction: A World First! The Web site introduces Neanderthal bone structure and guides visitors on a virtual tour of the reconstruction process. A series of annotated photos demonstrates how researchers and technicians recreated an adult Neanderthal skeleton, and includes a page listing the provenance of the fossil casts used for each bone. Visitors may also view side-by-side comparison sketches of the human and Neanderthal skeleton, and compare DNA sequences of the two hominids. Anyone interested in physical anthropology should enjoy the behind-the-scenes look at this first-ever Neanderthal reconstruction. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7049 This US Geological Survey database provides information on nonindigenous aquatic species for resource professionals and the general public. Distribution maps and species information for a variety of aquatic vertebrate, invertebrate, and plant species includes photos, description of the life cycle, native and non-native habitat range, and potential impacts the non-native species has on its habitat. The site is easy to navigate; users can find information by species name, state, or drainage basin. A number of links are provided for further information. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7316 This Web site from the United Nations Food and Agriculture Organization provides a vast amount of information on forestry and the state of the world's forests. Users can navigate through a forest cover map to select a country of interest. A report including geographic description, forest cover, ecological zones, and forest fire statistics is provided for each nation, along with forest management and forest product trade information. This site uses frames, which makes it easy to navigate through the large amount of information for each country. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7310 "DermNet, the award-winning Web site of the New Zealand Dermatological Society, aims to provide authoritative information about the skin for health professionals and patients with skin diseases." Information is organized separately for patients, general practitioners, and dermatologists. Some information is restricted to dermatologists who must register first, like the section of interesting cases. A useful part of the site is the skin conditions and treatments page. Over 250 skin conditions are described, most with photos, along with some general treatment options. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7540 Created by an enthusiast, this site is a unique compilation of botanical etymology from a broad range of sources. The list focuses on plants found in Southern California, but "many if not most of these names are in general use world-wide." A simple alphabetical listing of botanical words and their meanings and derivations allows for user-friendly navigation. A similar list of botanical terms enhances the usefulness of this resource. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=7536 The Website for GEBCO, the most comprehensive Bathymetric Chart of the world from UNESCO, and the International Hydrographic Organisation (IHO), now includes a gazetteer of undersea feature names. The downloadable Excel spreadsheet gives names and geographic data on undersea canyons, troughs, seamounts, banks, rises, channels, fracture zones, etc. The .pdf file gives the guidelines used in assigning undersea feature names, definitions of terms, and contact information for members of the GEBCO Sub-Committee on Undersea Feature Names and the Working Group on Maritime and Undersea Features of the United Nations Group of Experts on Geographical Names (UNGEGN). The 38 page text is in English and French. 2008-08-28 03:00:03 http://www.amser.org//SPT--FullRecord.php?ResourceId=5640 This animation illustrates the lumbosacral plexus including its origin, location, and distribution of main branches. This resource is from the Health Education Assets Library (HEAL). It requires the Flash plug-in. 2008-08-27 03:00:05 http://www.amser.org//SPT--FullRecord.php?ResourceId=5624 This animation portrays the process whereby chyme in the duodenum initiates inhibition of gastric secretion, by the same mechanisms which inhibit gastric motility. It supports understanding of the influence of gastric and intestinal factors on gastric secretion. Requires the Macromedia Flash plug-in. 2008-08-27 03:00:04 http://www.amser.org//SPT--FullRecord.php?ResourceId=5625 This animation portrays the sequence of events in hemostasis: 1. Adhesion; 2. Degranulation; 3. Aggregation; and 4. Consolidation.

Note that Ach is the transmitter secreted by all autonomic pre-ganglionic nerve terminals. Hence, all synapses between pre- and postganglionic fibers are cholinergic. 2008-08-27 03:00:04 http://www.amser.org//SPT--FullRecord.php?ResourceId=5628 This is a diagram if micturition from the Heath Eductaion Assets Library. This schematic diagram illustrates micturition or urinary bladder control, specifically the role of stretch receptors and neural messages to the brainstem and cortical centres. 2008-08-27 03:00:04
