10 of the Most Dangerous Chemicals in the World

10 of the Most Dangerous Chemicals in the World
Interesting — when I was in the Army, it was called CBR (chemical, biological, radioactive). I wonder why they changed the order and the initials? Pressure from Jay Leno? NBC was for Nuclear, Biological, Radiological. I think it might have been for memory's sake, which might have something to do with the tv studio indeed - but maybe just for giggles. When were you in? I was in back in the late 70s. I remember atropine was one of the drugs that was used to treat the immediate effects of nerve gas exposure. And we're supposed to believe that our benevolent government has truly decided to destroy all our VX stockpiles. I dunno, we've got much more targeted, devastating methods of wiping ourselves off the planet these days. I was in in the 90's. The husband, Mr. Related:  Chimica

Lucid Dream Inducing Plants by Krystle Cole by Krystle Cole Plants have been used for thousands of years to induce states of lucid dreaming by shaman throughout the world. These plants are often classified as oneirogens. Silene capensis Silene capensis, also known as African Dream Root, is a plant native to the Eastern Cape of South Africa, where it is regarded by the Xhosa people as a sacred plant. It is suspected that this sacred plant’s oneirogenic activity is due to triterpenoid saponins contained within its roots, although the exact pharmacological action is still unknown. Calea zacatechichi Calea zacatechichi, also known as Dream Herb, is a plant used by the indigenous Chontal of the Mexican state of Oaxaca. Its oneirogenic activity lies within its leaves which are usually boiled with water to make a tea and then drank directly before going to sleep. Entada rheedii Entada rheedii, also known as African Dream Herb, is a large woody liana or climber. References Bouncing Bear Botanicals. (2008). Mayagoitia, L., J.

WebElements Periodic Table of the Elements Nanoputian NanoPutians are a series of organic molecules whose structural formulae resemble human forms.[1] James Tour et al. (Rice University) designed and synthesized these compounds in 2003 as a part of a sequence of chemical education for young students.[2] The compounds consist of two benzene rings connected via a few carbon atoms as the body, four acetylene units each carrying an alkyl group at their ends which represents the hands and legs, and a 1,3-dioxolane ring as the head. Tour and his team at Rice University used the NanoPutians in their NanoKids educational outreach program. The goal of this program was to educate children in the sciences in an effective and enjoyable manner. They have made several videos featuring the NanoPutians as anthropomorphic animated characters. Construction of the structures depends on Sonogashira coupling and other synthetic techniques.

Presentata a San Diego la plastica che sanguina Un nuovo tipo di plastica "sanguina" quando viene danneggiata: imita la capacità della pelle umana di segnalare quando subisce danni e come la pelle sa autoripararsi. Il nuovo materiale, che si colora di rosso se si rompe ed è in grado di aggiustarsi da solo se viene esposto alla luce, è stato presentato al congresso della Società Americana di chimica in corso a San Diego. Lo ha messo a punto il gruppo della della University of Southern Mississippi coordinato da Marek Urban. Le potenziali applicazioni sono moltissime, vanno dai telefoni cellulari, ai computer portatili alle automobili. Per esempio i graffi sui paraurti delle automobili, potrebbero essere riparati semplicemente esponendo il graffio alla luce del sole e parti strutturali critiche degli aerei potrebbero invece avvertire di eventuali danni subiti. «Alcune autoriparazioni - ha proseguito - sono invisibili, ma ci aiutano a mantenerci vivi e in salute come il sistema che il Dna usa per riparare danni subiti dai geni.

John Conway's Game of Life The Game The Game of Life is not your typical computer game. It is a 'cellular automaton', and was invented by Cambridge mathematician John Conway. This game became widely known when it was mentioned in an article published by Scientific American in 1970. The Simulation The Rules For a space that is 'populated': Each cell with one or no neighbors dies, as if by solitude. Each cell with four or more neighbors dies, as if by overpopulation. Each cell with two or three neighbors survives. For a space that is 'empty' or 'unpopulated' Each cell with three neighbors becomes populated. The Controls Choose a figure from the pull-down menu or make one yourself by clicking on the cells with a mouse. Java version This page initially contained a Java applet and a Java application you can download. Game of Life Java applet Life is a bit - Edwin Martin <edwin@bitstorm.org>

How to Trick Your Brain for Happiness This month, we feature videos of a Greater Good presentation by Rick Hanson, the best-selling author and trailblazing psychologist. In this excerpt from his talk, Dr. Hanson explains how we can take advantage of the brain’s natural “plasticity”—it’s ability to change shape over time. gobyg There’s this great line by Ani Tenzin Palmo, an English woman who spent 12 years in a cave in Tibet: “We do not know what a thought is, yet we’re thinking them all the time.” It’s true. In recent years, though, we have started to better understand the neural bases of states like happiness, gratitude, resilience, love, compassion, and so forth. Ultimately, what this can mean is that with proper practice, we can increasingly trick our neural machinery to cultivate positive states of mind. But in order to understand how, you need to understand three important facts about the brain. Fact one: As the brain changes, the mind changes, for better or worse. Fact two: As the mind changes, the brain changes. 1. 2. 3.

Return to pictures of PVC projects CHIMICA sperimentale - Esperienze in home-lab: considerazioni di chimica sperimentale e altro "Alchimie nell'arte" è il titolo di un bellissimo saggio in un volumetto di 235 pagine del prof. Adriano Zecchina che si legge tutto d'un fiato e non lo si vorrebbe finire così presto. La presentazione in quarta di copertina così si conclude: -...questo libro cambierà il vostro modo di guardare ai colori utilizzati nelle opere d'arte. Naturalmente la frase è rivolta al gran pubblico, proverbialmente digiunissimo di chimica, e di chimica sperimentale ancor più; a me non ha certo cambiato il modo di guardare ai colori poichè fin da piccolo sempre li ho guardati e visti nelle loro due anime: quella cromatica e quella chimica; sono due anime per me indissolubili e sempre intrecciate. ---°°°OOO°°°--- Precipitando in laboratorio un sale solubile di mercurio con un solfuro esso si presenta sempre di colore nero (come tantissimi solfuri di metalli comuni), sotto la forma cristallina cubica. Così parlò il Maestro e così ho fatto io, con fiducia ed eccessivo ottimismo.
