In this second volume of Hanover, the trials, tribulations, and celebrations of the area are presented through extremely rare postcards. Among the events covered is the greatest test of the fortitude of the small town's residents: the August 21, 1915, tornado that caused enormous devastation and debris. Without the benefit of modern mechanized equipment, the community set out to clean up with a conviction to continue on with plans to celebrate Hanover's centennial only weeks later. Another milestone event occurred on June 14, 1932, when Hanover's residents celebrated the 200th anniversary of the birth of George Washington. Hanover Milestones also features scenes of industrial fires, celebrations marking the end of World War I, and the Hanover Fair.
More than a half-century ago, C. G. Chamberlayne, under the sponsorship of the Virginia State Library, transcribed, edited, and indexed a number of original Virginia parish vestry books, four of which are reprinted here. While the dates of coverage and lengths of the volumes vary, they are nonetheless similar in terms of scope and content. Each volume contains the oldest known records pertaining to that parish, in most cases beginning only a few years following the parish's date of formation. Mr. Chamberlayne begins each vestry book with an Introduction that pieces together the formation of the parish and important milestones in its history from published and original sources. Facsimilies of pages from the original vestry books, maps, and photographs help to put each volume into greater context, moreover. Appended to the vestry books are brief lists of the various parish ministers, with an indication of their earliest date of service as found in the records. The transcriptions themselves, ranging from about 250 to more than 600 pages of text, relate to the following issues growing out of the business affairs of colonial parish vestries; namely, payments to persons for services rendered to the parish, oaths and lists of oath-takers, news of the arrival of ministers, the appointment of church wardens, issues related to indentured servants, lists of tithables, payment of salaries and other obligations, the formation of parish precincts with the names of the families apportioned therein, the warding of children, and so on. In each case, these four scarce collections of colonial church records establish the existence of thousands of Virginia inhabitants, each of whom is easily found in the index or indexes at the back of the book.
When Santiago Ramón y Cajal started to unravel the fine structure of the nervous system in the last decades of the XIXth century maybe only his unbeatable soul of brave Spaniard imagined that most of the descriptions were scientific truths that lasted to date. Simple histological stainings, curiosity to ameliorate these, monocular microscopes, patience for drawing his observations and a rich imaginative open mind: this is the recipy for Cajal success. His descriptions of connectivity in the nervous system, compiled in Cajal's opus magna published in 1904 ("Textura del sistema nervioso del hombre y los vertebrados") and 1911 ("Histologie du systeme nerveux"), have been corroborated by modern techniques decade after decade. Even more, the main hypothesis that Cajal raised are universally recognised as biological laws, today: the neuron theory, the law on the dynamic polarization of the neuron and the chemotropic hypothesis. That is: the nervous system is not a sincitial network but is formed by individual cells; the transmission of the nerve impulses follow a main direction within a given neuron; the axons are guided by chemical substances in a chemotropic way, till form synapses with their targets. Attracted by Cajal's strong personality and scientific success, a number of medical students and doctors join him in the crusade to explore the nervous system. And the seed planted by the universal savant was really successful: Francisco Tello described interesting aspects of the regeneration of peripheral nerves which are very useful for neuroscientist currently working in this topic; Nicolás Achúcarro significantly contributed to study neuroglia and future microglia; Pío del Río-Hortega identified two out of the four main nervous cell types, the oligodendrocytes and microglia, and proposed an almost still valid classification for the CNS tumours; Fernando de Castro made was the first description of arterial chemoreceptors in the carotid body; Rafael Lorente de Nó was a dominant figure of Neuroscience for decades after the IInd World War, first describing the columnar organization of the cerebral cortex well before Mountcastle, Hubbel and Wiesel. Even less recognised co-workers and disciples of Cajal (his brother Pedro Ramón y Cajal, Domingo Sánchez, the neurologist Rodríguez-Lafora... protagonised discoveries that are consolidated scientific truths today). Altogether, it is difficult (if not impossible) to find a school in biology contributing in such a fundamental and variated way to the common acervo like the collectively known as Cajal School or Spanish Neurological School. Although the particular way to work of the Maestro, selecting a pleiade of brilliant collaborators with whom accomplish such a titanic feat, giving them freedom for their studies, has been recognised and confronted to antagonic systems followed by other relevant scientists and scientific schools, the general recognition of such a significant major milestones for Neuroscience and their vigency in the well-marched XXIst century is not: this is the purpose of this Ebook, to remind all these examples of how successful can be the scientific work when it is minutious, constant and performed by brilliant, imaginative and skilled scientists with a minimal conditions supporting their efforts.
This volume contains about 180 papers including seven keynotes presented at the 7th NUMIFORM Conference. It reflects the state-of-the-art of simulation of industrial forming processes such as rolling, forging, sheet metal forming, injection moulding and casting.
This Third Edition is the first English-language edition of the award-winning Meilensteine der Rechentechnik; illustrated in full color throughout in two volumes. The Third Edition is devoted to both analog and digital computing devices, as well as the world's most magnificient historical automatons and select scientific instruments (employed in astronomy, surveying, time measurement, etc.). It also features detailed instructions for analog and digital mechanical calculating machines and instruments, and is the only such historical book with comprehensive technical glossaries of terms not found in print or in online dictionaries. The book also includes a very extensive bibliography based on the literature of numerous countries around the world. Meticulously researched, the author conducted a worldwide survey of science, technology and art museums with their main holdings of analog and digital calculating and computing machines and devices, historical automatons and selected scientific instruments in order to describe a broad range of masterful technical achievements. Also covering the history of mathematics and computer science, this work documents the cultural heritage of technology as well.
