Nomenclature is the compilation of descriptions of things and technical terms in a special field of knowledge, the vocabulary ofa technical language. In the history of chemistry, a systematic nomenclature became significant only rather late. In the early times of alchemy, the properties of the substance or its appearance played a major role in giving a compound a name. Libavius was the first person who tried to fix some kind of nomenclature in Alckeinia in 1,597. In essence, he gave names to chemical equipment and processes (methods, names that are often still valid in our times. [Pg.18]

Bromosafrole is a great stepping stone to final product and was, in fact, the exact precursor used by Merck who was the first person to synthesize MDMA. Until very recently it was the defacto method that most underground chemists started out with (Someone-Who-Is-Not-Strike included) because, at first glance, it seems so simple and uses basic chemicals and equipment. Once someone has the bromosafrole, all one has to do is just swap out that Br with simple ammonia or methylamine and the deed is done. [Pg.142]

Since completing my synthesis of safrole using the methods described here, I have learnt that I am the first person in the world to do so. There may be areas in my procedures that can be improved. What I am doing here is giving you my best shot as well as a fairly detailed account of my experiences. [Pg.235]

Henry Bessemer, the great Victorian ironmaster and the first person to mass-produce mild steel, was nearly bankrupted by this. When he changed his suppliers of iron ore, his steel began to crack in service. The new ore contained phosphorus, which we now know segregates badly to grain boundaries. Modern steels must contain less than =0.05% phosphorus as a result. [Pg.19]

Everyone has seen the demonstration in which you start off by telling a story to the first person in a group. The story is then passed on to the next person, and so on down the line. By the time the story gets back to the original storyteller, the message has changed. In this case, if they had a written script similar to a JHA, then the story would have been the same message around the room. [Pg.52]

You will greatly enhance the effectiveness of any communications medium if you are able to incorporate favorable anecdotes from participants in the pilot test. First-person accounts of positive experience lend considerable credibility, and you may wish to consider recruiting the test-site facility manager (or other personnel) to assist the team. [Pg.167]

William Thomas Brantle (17B8-1866) was born in London, England. Trained as an apothecary, he became a lecturer in chemistry at the University of London in 1808 and was a professor at the Royal Institution from 1813 to 1852. His scientific achievements were modest, although he was the first person to discover naphthalene, now used in mothballs. [Pg.2]

In 1903, the Curies received the Nobel Prize in physics (with Becquerel) for the discovery of radioactivity. Three years later, Pierre Curie died at the age of 46, the victim of a tragic accident. Fie stepped from behind a carriage in a busy Paris street and was run down by a horse-driven truck. That same year, Marie became the first woman instructor at the Sorbonne. In 1911, she won the Nobel Prize in chemistry for the discovery of radium and polonium, thereby becoming the first person to win two Nobel Prizes. [Pg.517]

The first person to identify a pattern in the lines of the visible region of the spectrum was Joseph Balmer, a Swiss schoolteacher. In 1885, he noticed that the frequencies of all the lines then known could be generated by the expression... [Pg.131]

The timing of the training session for each trainee group will again partly depend on the way you have organized your scheme. Thus, if the program co-ordinator needed any briefing at all, he or she would probably have been the first person to receive it and this would have occurred very early on in the life... [Pg.283]

Ernest Rutherford was the first person to observe a binuclear reaction, hi 1919, he exposed a sample of nitrogen to a particles from a naturally radioactive source. He observed the production of protons and deduced from the requirements of charge and mass balance that the other product was oxygen-17 ... [Pg.1574]

My first personal contact to Henk Timmerman happened on the wonderful island of Capri during a symposium on pharmaceutical sciences. Henk Timmerman headed one of the largest and most important departments of Medicinal Chemistry in European academia. It was very impressive to face his views on our research field, and his integrated and straightforward way to guide research projects. For several years I collaborated with his group and, as an added bonus, became a great fan of Amsterdam. [Pg.499]

The first person to identify the hydrogen ion as a component of all atoms was Ernest Rutherford. Rutherford had his hand in virtually every aspect of atomic research. By 1919, he had discovered alpha and beta rays, found a new element (radon), won a Nobel Prize for his work with radioactive elements, and demonstrated that atoms had nuclei. For good measure, in 1914, he was knighted. However, still more discoveries and honors awaited him. [Pg.30]

Markus told me that Wayne was perhaps the first person to see the need to plan a special RM meeting, and that he and Markus had already met, in the 1970 s, before this meeting was organized. Markus said of those early days ... [Pg.293]

Robert Boyle (1627-1691), an Irish chemist, was the first person to classify certain chemicals as either acids or bases. Boyle based his classifications on their properties. He was unable to explain, however, why acids and bases have the properties that they do. It would be another 200 years before a scientist came along to answer that question. That scientist was the Swedish chemist Svante Arrhenius (1859-1927). [Pg.15]

Frankland discovered the fundamental principle of valency—the combining power of atoms to form compounds. He gave the chemical bond its name and popularized the notation we use today for writing chemical formulas. He codiscovered helium, helped found synthetic organic and structural chemistry, and was the father of organometallic chemistry. He was also the first person to thoroughly analyze the gases from different types of coal and—dieters take note—the first to measure the calories in food. [Pg.43]

In the early 1980s, the world witnessed the sale of the first personal computers. Its transition from the relatively bulky and slow first units to the sleek, speed demons has made the computer truly revolutionary. With each improvement in computers, however, comes the increasing problem of what to do with the ever increasing number of computer e-wastes. The U.S. EPA estimates that nearly 250 million computers will become obsolete in the next five years in the United States alone. Unfortunately, only approximately 10% of these old computers that are retired each year are being recycled. This presents a substantial concern because toxic elements such as lead, cadmium, mercury, barium, chromium, beryllium as well as flame retardant, and phosphor are contained in a typical computer and there would be potential harm if there was a release of these elements into the environment.1... [Pg.1230]

Writing equation (6) in logarithmic form results in equation (7). Again by convention, the log ionization ratio, log / = log(CfiH+ /Cb), is defined, with the ionized form on top. Equations (6) and (7) are thermodynamically exact the problem with them has always been what to do about the unknown activity coefficient ratio term. The first person to tackle this problem was Hammett,21 22 who defined an acidity function, H0, as in equation (8) ... [Pg.4]

Poul la Cour (1846-1908), a Danish pioneer who constructed the first wind turbine for the generation of electricity, was also probably the first person to supply an electrolyzer with electrical energy from wind turbines to produce hydrogen for gas light [46]. [Pg.177]

In December 1997, when the idea for this book was in its infancy, I saw Elizabeth Schuster s name and address on a list of new subscribers to an MCS newsletter. The listing caught my eye because she lives near my mother. Out of the blue I called Elizabeth to ask if I could interview her when I came to spend the holidays with my mother. She was the first person interviewed for this project, and I have since marveled at that good fortune. I found Elizabeth to be a woman of wonderful peace and grace. Hearing her story reconfirmed my belief in the healing power of stories, and strengthened my resolve to see this project to completion. [Pg.19]

That night we went to a hotel, and the next day I started making calls from my bed. The first person I contacted, at the health department, said, Your symptoms are consistent with a high level exposure to ozone. I called the EPA and anybody else I was referred to in every conversation. [Pg.160]

In the narrative that follows, Curt Schuster articulates some of the issues faced by spouses, and his style of coping. Although it wasn t planned, his wife Elizabeth was the first person interviewed for this collection and he was the last. In my opinion, I couldn t have chosen more appropriate bookends. ... [Pg.249]

With the aid of William Strunk and E.B. White in The Elements of Style and that of William Zinsser in On Writing Well, Rudolph Flesch in The ABC of Style, and D.L. Carson, whose comments appear in this book, I have tried to follow some principles of technical communication lately ignored in scientific texts use the first person, put yourself in the reader s place, and, the best for last, use the active voice and a personal subject. [Pg.333]

Billington, in fact, was the first person to commit any crime in the colony, as far as we know today. He was also the first to be executed by the state in the New World. Billington s crime was to shoot a man named John Newcomen, for reasons which are lost to history. [Pg.78]
