Download or read book A Modified Decade Scaler written by George N. Rupert and published by . This book was released on 1949 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automatic decade scaler which operates for a fixed number of counts has been developed for use with a Geiger tube. The elapsed counting time is read by a 115V AC clock to 0.01 minute. Manual operation is provided to allow the scaler to be run for a fixed time interval in which case every 10,000 counts are recorded by a Cyclotron recording meter. The instrument has a two pulse resolution time of 25 microseconds. Four decades in cascade are used in the scaler, one of which has a resolution time of 8 microseconds; the other three, a resolution time of 30 microseconds. Ten neon bulbs are used in each decade to indicate the count.

This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the conference on "Atomic and Nanometer Scale Modification of Materials: Fundamentals and Applications" which was co-sponsored by NATO and the Engineering Foundation, and took place in Ventura, California in August 1992. The goal of the organizers was to bring together and facilitate the exchange of information and ideas between researchers involved in the development of techniques for nanometer-scale modification and manipulation. theorists investigating the fundamental mech anisms of the processes involved in modification, and scientists studying the properties and applications of nanostructures. About seventy scientists from all over the world participated in the conference. It has been more than 30 years since Richard Feynman wrote his prophetic article: ''There is Plenty of Room at the Bottom" (Science and Engineering, 23, 22, 1960). In it he predicted that some day we should be able to store bits of information in structures composed of only 100 atoms or so, and thus be able to write all the information accumulated in all the books in the world in a cube of material one two-hundredths of an inch high. He went on to say, "the prin ciples of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. " Since that time there has been significant progress towards the realization of Feynman's dreams.
Download or read book Natural Climate Variability on Decade to Century Time Scales written by Climate Research Committee and published by National Academies Press. This book was released on 1996-09-13 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reflects the current state of scientific knowledge about natural climate variability on decade-to-century time scales. It covers a wide range of relevant subjects, including the characteristics of the atmosphere and ocean environments as well as the methods used to describe and analyze them, such as proxy data and numerical models. They clearly demonstrate the range, persistence, and magnitude of climate variability as represented by many different indicators. Not only do natural climate variations have important socioeconomic effects, but they must be better understood before possible anthropogenic effects (from greenhouse gas emissions, for instance) can be evaluated. A topical essay introduces each of the disciplines represented, providing the nonscientist with a perspective on the field and linking the papers to the larger issues in climate research. In its conclusions section, the book evaluates progress in the different areas and makes recommendations for the direction and conduct of future climate research. This book, while consisting of technical papers, is also accessible to the interested layperson.

Download or read book Small Scale Soil less Urban Agriculture in Europe written by Silvio Caputo and published by Springer Nature. This book was released on 2022-06-01 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Monograph focuses on the new approaches that urban agriculture offers to grow food in cities. The author paints a dynamic picture of soil-less and indoor techniques that are currently emerging. A growing number of small scale community-led and entrepreneurial initiatives are using such techniques for diverse objectives: to increase resource efficiency; to strengthen food security; to educate and inform or to exploit new market opportunities. The described studies demonstrate how technologies that are typically used in high-tech food production can also be harnessed in small projects to generate social and economic benefits at a local level. The author puts a focus on three aspects: to outline the context within which small scale soil-less urban agriculture is developing in Europe; to give an overview of the state-of-the-art of projects focusing on this area through case study analysis and to elaborate on emerging questions. Such questions include: is the use of soil-less urban agriculture changing the relationship with, and perception of, what is natural and sustainable for urban farmers and small enterprises working in this sector? What is the perceived potential of these soil-less and indoor forms of urban agriculture to meet environmental, social and economic goals? By answering these and other questions, the volume is a valuable resource for researchers in agriculture and sustainability, as well as urban farmers.

Download or read book New Strategies for America s Watersheds written by National Research Council and published by National Academies Press. This book was released on 1999-04-28 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emergence of a toxic organism like pfisteria in tributaries of the Chesapeake Bay has focused public attention on potential hazards in our water. More importantly, it has reminded us of the importance of the entire watershed to the health of any body of water and how political boundaries complicate watershed management. New Strategies for America's Watersheds provides a timely and comprehensive look at the rise of "watershed thinking" among scientists and policymakers and recommends ways to steer the nation toward improved watershed management. The volume defines important terms, identifies fundamental issues, and explores reasons why now is the time to bring watersheds to the forefront of ecosystem management. In a discussion of scale and scope, the committee examines how to expand the watershed from a topographic unit to a framework for integrating natural, social, and economic perspectives as they share the same geographic space. The volume discusses: Regional variations in climate, topography, demographics, institutions, land use, culture, and law. Roles and interaction of federal, state, and local agencies. Availability or lack of pertinent data. Options for financing. The committee identifies critical points in watershed planning to ensure appropriate stakeholder involvement and integration of science, policy, and environmental ethics.
