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 ): Igor Filippov
Corkboard Connections: Hands-on Water Cycle Fun! Now that I'm retired, I often miss working with children; children are my inspiration and the classroom is my laboratory! Recently I accepted a position at a local school to work with kids during their year round intersession program, and I had the pleasure of teaching science to 5th graders for 3 days. I had a wonderful time teaching them about the water cycle and weather, especially since I was able to incorporate a hands-on activity and an exciting demonstration into our lessons. One activity was adapted from a terrific idea shared with me by Pat Calfee, a former elementary teacher who is now an educational consultant. When Pat was teaching 2nd grade, she used plastic rotisserie chicken containers to have her students create mini water cycles. Because 5th graders need to know the full water cycle including transpiration and run-off, we modified our mini water cycles slightly. Those containers were a super way to give students hands-on experience creating a water cycle.
SPECAMP : spectres UV-Visible, IR et RMN SPECAMP est un logiciel gratuit (réalisé par Serge LAGIER) permettant de visualiser, exploiter et enregistrer des spectres UV/Visible, IR et RMN du proton. SPECAMP exploite les fichiers au format JCAMP (Joint Committee on Atomic and Molecular Physical Data), qui est un format standard d’échange de données chimiques et spectroscopiques. JCAMP a été officiellement utilisé dès 1988 ; depuis 1995, l’IUPAC (International Union of Pure and Applied Chemistry) gère ce format et le dernier protocole date de 2005. Le format JCAMP-DX est un format ouvert et les données d’un fichier (extension .jdx) peuvent être visualisées, corrigées et annotées avec un simple éditeur de texte. De nombreux exercices interactifs sont également proposés. Où télécharger le logiciel SPECAMP ? Vous pouvez télécharger le logiciel SPECAMP ici : Une notice d’utilisation à destination du professeur est disponible ici : Le fichier d’aide de SPECAMP est disponible ici : 1.
NCI/CADD Group Chemoinformatics Tools and User Services Budapest, Hungary | Sighting Opportunity | Spot The Station | NASA How do I Spot The Station? What does all this sighting information mean? Time is when the sighting opportunity will begin in your local time zone. All sightings will occur within a few hours before or after sunrise or sunset. This is the optimum viewing period as the sun reflects off the space station and contrasts against the darker sky. Visible is the maximum time period the space station is visible before crossing back below the horizon. Max Height is measured in degrees (also known as elevation). Appears is the location in the sky where the station will be visible first. Disappears represents where in the night sky the International Space Station will leave your field of view.

11 Elképesztő matek trükk, amit nem tanítanak az iskolában! A matematika nem tartozik a legkönnyebb tantárgyak közé, ráadásul a matektanárok is minden más tantárgynál jobban szeretik túlbonyolítani még az egészen egyszerű alapokat is, így nem csoda, ha a gyerekek már egészen fiatal korukban megutálnak mindent ami a számokkal kapcsolatos. Pedig nem feltétlenül kellene, mert még ha sablon szövegnek is tűnik, a matematikának bizony megvan a maga szépsége, és még az egyébként nehezebb törteket is képesek lehetünk pofonegyszerű módszerekkel, fejben kiszámolni. Ehhez persze ismerni kell magukat a módszereket, amiket sajnos sokszor nem, vagy nem kellően tanítanak meg a diákoknak. Most 11 fantasztikus matek trükköt szedtünk össze nektek az internetről, melyek ha nem is megszerettetik majd mindenkivel a matekot, de garantáltan egy kis érdeklődést keltenek majd mindenkiben akik nem kattintottak el rögtön a ,,matek” szó hallatán! Hogyan váltsunk át Celsius fokról Fahrenheit-re és vissza Hogyan szorozzunk nagy számokat, gyorsan, fejben
Online chemical modeling environment (OCHEM): web platform for data storage, model development and publishing of chemical information Gravitációs hullám ChemSpider - Database of Chemical Structures and Property Predictions If the Moon Were Only 1 Pixel - A tediously accurate map of the solar system Mercury Venus Earth You Are Here Moon Mars Jupiter Io Europa Ganymede Callisto Saturn Titan Uranus Neptune Pluto(we still love you) That was about 10 million km (6,213,710 mi) just now. Pretty empty out here. Here comes our first planet... As it turns out, things are pretty far apart. We’ll be coming up on a new planet soon. Most of space is just space. Halfway home. Destination: Mars! It would take about seven months to travel this distance in a spaceship. Sit back and relax. When are we gonna be there? Seriously. This is where we might at least see some asteroids to wake us up. I spy, with my little eye... something black. If you were on a road trip, driving at 75mi/hr, it would have taken you over 500 years to get here from earth. All these distances are just averages, mind you. If you plan it right, you can actually move relatively quickly between planets. Pretty close to Jupiter now. Sorry. Lots of time to think out here... Pop the champagne! We're always trying to come up with metaphors for big numbers.
