A Guide to the Congestion Mitigation and Air Quality Improvement Program
Author: United States. Federal Highway AdministrationPublisher:
ISBN:
Category : Air
Languages : en
Pages : 48
Book Description
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) established the Congestion Mitigation and Air Quality Improvement (CMAQ) Program. The CMAQ Program emphasizes the importance of the link between transportation and air quality, by providing 6 billion dollars between 1992-1997 for transportation projects and programs to improve air quality. Consequently, many areas will be able to implement transportation control measures (TCMs), in compliance with the mandates of the Clean Air Act Amendments of 1990 (CAAA).

Variability of Blazars
Author: E. VALTAOJA (Ed)Publisher: Cambridge University Press
ISBN: 9780521413510
Category : Science
Languages : en
Pages : 484
Book Description
Blazars (also known as BL Lac objects), first discovered in 1978, are unusually energetic objects in the extragalactic universe. About 200 are known or suspected. They are radio sources with highly variable optical and radio emission, as well as high polarisation, and their optical spectra normally have no distinguishable features. It is generally accepted that they belong to that class of galaxies with active galactic nuclei, which are presumed to be driven by infall of matter to a supermassive black hole. In this book researchers give a complete summary of the observations of blazars and the theoretical interpretation. A comprehensive listing of confirmed and candidate objects is included. Mechanisms in which the variability can arise from shocks and relativistic jets are discussed. There are at least four different answers given to the question: what is a blazar? This book is a complete overview of the violent activity observed in these extreme active galactic nuclei.
