Switzerland travel

After a fire in a chemical storehouse at Schweizerhalle, Switzerland, in November 1986, several tons of various pesticides, solvents, dyes, and other raw and intermediate chemicals were flushed into the Rhine River (Capel et al., 1988 Wanner et al., 1989). Among these chemicals was the insecticide disulfoton, of which 3500 kg were introduced into the river water (11°C, pH 7.5). During the 8 days travel time from Schweizerhalle to the Dutch border, 2500 kg of this compound were eliminated from the river water. Somebody wants to know how much of this elimination was due to abiotic hydrolysis. Since in the literature you do not find any good kinetic data for the hydrolysis of disulfoton, you make your own measurements in the laboratory. Under all selected experimental conditions, you observe (pseudo)first-order kinetics, and you get the results given below. 

At age 12, Robert was sent (with his brother and an academic tutor) on a European tour that was to have a strong formative influence. His keen interest in mathematical studies was first kindled by travels in France and Switzerland. At age 13, he also experi-led to intense religious conversion and convictions that he maintained throughout life in the words of a biographer,... 

Not only did Freund move freely about campus, but she became a fervent traveller, wheelchairing her way around England, Scotland, Germany, Austria, Switzerland, and Italy. 

Fritz, meanwhile, was startled to discover that his wife wasn t happy just minding her own business at home with an adolescent stepson and newborn daughter. He was upset when she announced her plans, on just a few days notice, to travel to a resort in Switzerland. When Haber became crippled by one of his periodic nervous breakdowns, he blamed his wife, calling her demands thumbscrews of the soul. ... 

Haber felt himself growing weaker and blamed the damp English climate. As so often, he sought to escape from his agonies through travel. He wrote to Rudolf Stern, asking his friend and doctor to accompany him to a sanatorium in Locarno, Switzerland. The two arranged to meet in Basel. 

From Enkhuisen Seton traveled to Amsterdam and Rotterdam, giving demonstrations of his skill in both cities. He took a ship from Rotterdam, disappearing for over a year. We next pick up his trail in Zurich, Switzerland, where he obtained a letter of introduction to the scientist Dr. Jacob Zwinger of Basel. He traveled to Basel in the company of Professor Wolfgang Dienheim of Freiburg, who wrote a detailed record of everything that took place. Part of this report follows ... 

H.U.S. wishes to thank the DAAD and for a travel grant under the Project 313/S-PPP-3/95. Some of the calculations were performed at the Centro Svizzero di Calcolo Scientifico (CSCS) in Manno (Switzerland). 

Cleve s early schooling was in Stockholm, and after passing final examinations he went to Uppsala, Sweden, to study mineralogy and other sciences. Cleve earned a master s degree (M.Sc.) at the age of twenty-two years and completed his doctorate (Ph.D.) just one year later. During these years he received several travel grants that enabled him to visit laboratories in France, England, Italy, and Switzerland. 

In the autumn of 1929, Wolfrom was appointed Instructor in Chemistry at The Ohio State University, and one year later was raised to the rank of Assistant Professor. He remained on the faculty of the Department of Chemistry at Ohio State for the whole of his career, becoming Associate Professor in 1936, and Professor in 1940. In 1939, he was awarded a Fellowship by the John Simon Guggenheim Memorial Foundation, and, in February of that year, he travelled to Switzerland, to work in the laboratory of Professor P. Karrer of the University of Zurich, but he returned to the United States at the outbreak of hostilities in Western Europe.

John Ulric Nef (Herisau, Switzerland, 14 June i862 Carmel, California, 13 August 1915) was taken in 1864 to the United States. He entered Harvard University in 1884 but in the same year went to, Europe with a travelling scholarship and studied with Baeyer in Munich, taking his Ph.D. in 1886. In 1887 he was appointed in Purdue University, Indiana, in 1889 at Clark University, Worcester, Mass., and in 1892 as professor in the new University of Chicago, where he spent the rest of his life. Nearly all his work he carried out himself with one assistant, and he published over 30 papers in his own name. Nef supposed that chemical reactivity depends on dissociation and on the additive power of the substituting molecule in virtue of its residual affinities ... 

I The Gotthard Base Tunnel network is being built under the Alps from Switzerland to Milan, Italy. At about 35 miles, the two-way tunnel will be the longest in the world and will reduce the time to make the trip by automobile from 3.5 hours to 1 hour. High-speed trains traveling at speeds of 155 miles per hour will make more than two hundred trips through the tunnel per day. 

Erringtons schedule in the summer and autumn of 1947 provides a representative portrait of his day-to-day activities in this period. In the summer he travelled to England, France, Switzerland, and Italy to line up sales agents to handle Eldorado s radium business abroad. By September he had negotiations under way with potential agents in Argentina, Brazil, India, Mexico, Norway, Switzerland, and South Africa. Later Australia and China were added to the list.
