Love `em or hate `em you can´t get away from trains in the UK. Everywhere you go from the biggest city to the most solitary spot you´re sure to find new generation rolling stock or ancient relics to remind you of Britain´s great railway heritage not too far away if you look hard enough. In Praise Of Rails is a collection of fifty railway-related poetic gems that will inspire you to find out more about the memorable locomotives, events, people and places that have shaped our island race''s unique obsession with all things trains, that began with the starch-shirted days of Stephenson''s Rocket and still survives today with the sleek and sexy Eurostar.*Cover illustrations by John Wardle.

Typewritten essay for History 132a, given in 1945-1946 by Sidney Fay.

In a salt marsh at the head of the Bay of Fundy, where the tidal range is 15 m, and the marsh is flooded only on highest tides, the above-ground annual production of Spartina alterniflora averaged 715 g m-2 dry weight, with a range of 324-1031g m-2. Puccinellia americana occupied the tops of the creek-side levees, and Spartina pectinata occupied the upland border where fresh water entered the marsh. The mean production for all species was 483 g m-2 yr-1 dry weight; this was lower than the production of marshes on the Atlantic and Gulf coasts of Nova Scotia where the tidal range is about 2 m and the marshes are flooded on every tide. Export was monitored by comparing similar quadrats at different times of year. Major export was during the winter by ice rafting; there was little export in the summer. Impoundment of areas of about 20 ha to encourage duck breeding resulted in death of the salt marsh plants and elimination of the export by ice rafting.

Papers of a Methodist missionary and pioneer who migrated to Oregon during the Great Reinforcement in 1840, and was involved in the formation of the Oregon provisional government in 1843. The collection includes: letters to and from Judson, 1829-1877, Adelia Leslie, Judson''s sister, and David Leslie, her husband, circa 1840-1890. Correspondents include Asahel Bush, Francis W. Pettygrove, and Elijah White.

"It has not been possible in the past to characterize a transistor or other semiconductor device with regard to its performance in a fast neutron (Eu003e10keV) environment when the device is operated at high (u003e100 MHz) frequencies. Using the scattering (s- ) parameter concept, which regards a device as a two-port "black box", a full characterization of the trends in the neutron bombarded high-frequency performance of a typical transistor can be made. Scattering parameters are not only an accurate means of describing the high-frequency performance of any device, but are now reasonably easily measured with the advent on the market of reliable, highly accurate s-parameter test sets. Methods which exist to permit the rapid design of high-frequency transistor circuits, once the device scattering parameters are known, are reviewed. The effects of neutron bombardment on a high-frequency transistor amplifier are found to be generally enhancing, rather than degrading as expected, if the device is operating near or above the published minimum f[subscript T]"--Abstract, leaf i.
