He published his results in

William Beaumont (1785-1853) experimented with the gastric juices of a patient with a permanent hole in his stomach. He published his results in 1833, and was the first to explain how the stomach conld digest food. Extracts from this publication are fascinating ... [Pg.69]

Professor Torbem Bergman had requested Scheele to investigate pyrolusite and he did so. In 1774 he published his results in an important paper [27.2]. This was of great importance in the history of element discoveries and for chemistry as a whole. [Pg.633]

That autumn, in Montreal, Rutherford began to make experimental measurements of the heat released by radioactive processes. From studies of the details of alpha emission he succeeded in identifying all the chain of decays through which U transmuted into a stable substance. He published his results in 1905 and, with that paper, the transmutation theory became a solid working hypothesis. It took account of what was known, explaining every variation in radioactivity that experiments could create. It established the new principle that a radioactive element could be identified by its half-life. [Pg.2]

Copenhagen in 1803 and applied to the university for a position as professor of physics, then called natural philosophy, but was refused. He continued lecturing at the university in the schools of medicine and pharmaceuticals, and at the same time managed the pharmacy, carried on electrochemical experiments, and published his results. In 1806 he was finally made a professor of physics at the University, although he not become a full professor until 1817. [Pg.896]

In 1975 Vannice published a comprehensive study of the kinetics of the methanation of carbon monoxide over various metals.45 He analysed his results in terms of a rate-determining step for the reaction involving the interaction of adsorbed CHOH species and adsorbed H atoms ... [Pg.40]

Stiiadecki discovered element 44 in 1808 while working with platinum ores from South America. After he published his results, other chemists tried to find the element as well. They were unsuccessful. Sniadecki became discouraged, dropped his claims of discovery, and did no further research on the element. [Pg.506]

The author of artificial hydraulic lime, produced by the burning of the interground mixture of choc and clay was L.J. Vicat, which published his results in 1818. He can be recognised as the predecessor of the technology of Portland cement production. [Pg.3]

The first indication of a connection between a diet-related elevated cholesterol exposure and heart disease in humans came from the Dutch physician Cornelis D. de Langen. In 1916, he reported from the Dutch East Indies (nowadays Indonesia), that the natives had a considerably lower cholesterol level than the Dutch colonists. He attributed this to their different dietary habits. Whereas the diet of the Dutch was very rich in meat, the natives lived mainly on vegetables and rice. Within the framework of an epidemiological study, he could prove that the cholesterol level of the latter rose by around 27 %, if they changed their diet to that of the Dutch. Regrettably, de Langen published his results in Dutch, in a journal, which received little attention from the experts. [Pg.409]

Biopotential recordings from the head reflect the bioelectric function of the brain. This recording is known as an electroencephalogram (EEG). The first systematic recording of the human EEG is attributed to the Austrian psychiatrist Dr. Hans Berger, who published his results in 1929. By using a primitive galvanometer and surface electrodes placed on his son s scalp, he showed the EEG as a rhythmic pattern of electrical oscillation. [Pg.435]

Despite its foundation in dubious hypothesis and its erroneous initial results, Dalton s theory was just the breakthrough that was needed. For the first time it allowed chemists to interpret mass relationships rationally. In 1808 he published his findings in his book New System of Chemical Philosophy, at the age of 42. [Pg.179]

Determination of the water composition became a major advance of the oxygen theory. In 1781 H. Cavendish observed that inflammable air upon combustion is transformed almost completely (together with dephlogisticated air) into pure water. But he published his results only in 1784. Lavoisier knew about these experiments and, after repeating them, he concluded that water is not a simple substance but a mixture of inflammable and invigorating air. Since the conclusion was made in 1783, Lavoisier is held by many to be the first one to have established the composition of water. In reality, however, H. Cavendish was the first. Determination of the composition of water made it possible to get an insight into the nature of hydrogen. [Pg.59]

Alfred Delville (88) also performed Monte Carlo simulations independently to study the clay-water interface and published his results in the same year as Skipper and coworkers. However, he used the water-water potential parameters... [Pg.76]

In the Menachan valley in Gregor s own parish he found and investigated a black sand and published his results in the German Science Journal Crell s Annalen in 1791. A summary ... [Pg.497]

A chemist has performed a chemical reaction and has captured a gas that forms, noticing that 68.2 mL of the gas formed at temperature of 25°C and a pressure of 753 torr. He wishes to publish his results in a chemistry journal but realizes that he must express this volume at STP. What is the volume at STP ... [Pg.243]

In a article " published in 1869, Mr. Lindelof recalls a principle stated in the work written jointly by him and Mr. Moigno, a principle which I menhoned in 81 he draws on the general formulas and the exact numbers relahng to the limiting height of the partial catenoid between bases whose diameters have between them an arbitrary raho, and he displays his results in two tables. [Pg.68]
