There is Such a Thing as a Free Lunch: Freely Accessible Databases for the Public Sandy Lewis Sciences and Engineering Librarian & Library Instruction Coordinator University of California, Santa Barbaraslewis@library.ucsb.edu Introduction Most of us are aware that there are free bibliographic databases available on the web.
Carl UnCover, ERIC, Agricola, and all of the flavors of Medline are the ones that first come to mind. Many of our libraries are open to community users and if you've ever been the one to break the bad news, "I'm sorry, our databases are not accessible off-campus," or the real clincher, "Only (insert your school name here) faculty, staff and students are authorized to use our databases from off-campus," then you have probably seen reactions ranging from sad disappointment to outright indignation. The first time I compiled this list of databases, I included references sources such as InfoPlease and the patent databases.
Methodology The Databases AIDSLINE: Internet Archive: Universal Library. An early collection of books from the Indian scanning centers of the Universal Library Project, sometimes called the Million Books Project.

Alloy For Solder. Can we grow a stronger-than-steel 'wonder material' to save the world? It’s stiffer than Kevlar, thinner than paper, and in a few years, it may be mass-produced using only sunlight and water.
Scientists in the US this week announced a new, and potentially groundbreaking method for producing nanocellulose — a so-called "wonder material" derived from tree fiber that could be used to create ultra-thin displays, lightweight body armor, and a wide range of other products. Their key ingredient? Algae. Neo-Tribal "Epoxy"/AKA Cutler's Resin - The Knife Network Forums : Knife Making Discussions. A few minutes ago, I glued a blade in a piece of antler using the pine pitch glue.
My mix called for 3 parts pitch, 1 part bees wax, and 2 parts moose dung. The dried moose dung was hammer forged (cold) on the kitchen counter basically to a coarse powder. I melted the pitch and the wax in an old soup can, then stirred in the hand forged powdered dung to form the glue. I did this in my kitchen on the gas range. Pitch smokes a lot when melting.

L'huile de ricin est une huile végétale obtenue à partir des graines de ricin. Elle est incolore à jaune très clair. Les triglycérides (triples esters de glycérol et d'acides gras) dont elle est constituée comptent pour environ 90 % de ses acides gras un acide gras en C18, oméga-9 et hydroxylé : l'acide ricinoléique ou acide (R)-(+)-12-hydroxy-9Z-octadécénoïque. Utilisation[modifier | modifier le code] Toxicité[modifier | modifier le code] L'acide ricinoléique altère la muqueuse intestinale et provoque des pertes importantes en eau et en électrolytes (sels minéraux), d'où son action purgative intense et irritante.
Borax. Un article de Wikipédia, l'encyclopédie libre.
Le borax est une espèce minérale de formule (Na2B4O7•10H2O). C'est un minerai de bore appelé aussi tétraborate de sodium décahydraté ou borate de sodium. Silicon. Silicon is a chemical element with the symbol Si and atomic number 14.
It is a tetravalent metalloid, less reactive than its chemical analog carbon, the nonmetal directly above it in the periodic table, but more reactive than germanium, the metalloid directly below it in the table. Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823. In 1808, it was given the name silicium (from Latin: silex, hard stone or flint), with an -ium word-ending to suggest a metal, a name which the element retains in several non-English languages. Silly Putty. Silly Putty drooping through a hole Silly Putty is a toy based on silicone polymers which display unusual physical properties.
