Transportation conformity is required under the Clean Air Act (CAA) Section 176(c) to ensure that Federally-supported transportation activities are consistent with (“conform to”) the purpose of a State Implementation Plan (SIP). Transportation conformity establishes the framework for improving air quality to protect public health and the environment. Conformity to the purpose of the SIP means Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) funding and approvals are given to highway and transit activities that will not cause new air quality violations, worsen existing air quality violations, or delay timely attainment of the relevant air quality standard, or any interim milestone. This Guide was prepared to help State and local officials understand transportation conformity and how conformity requirements relate to transportation investments in their communities. Specifically, the implications of conformity on metropolitan transportation plans, transportation improvement programs (TIPs), and transportation projects are discussed. The Guide provides overview information on the major elements of the conformity process and provides answers to basic questions. Several exhibits are included in the Guide to illustrate key elements of the conformity process. Appendices are also included that discuss the health effects of pollutants, options to reduce on-road mobile source emissions, and resource agency contacts.

This book presents the first detailed and comprehensive study of information highlighting in advanced learner language, echoing the increasing interest in questions of near-native competence in SLA research and contributing to the description of advanced interlanguages. It examines the production and comprehension of specific means of information highlighting in English by native speakers and German learners of English as a foreign language, presenting triangulated experimental and learner corpus data as corroborating evidence. The study focuses on learners' use of discourse-pragmatically motivated variations of the basic word order such as inversion, preposing, and it- and wh-clefts, an underexplored field in SLA research to date.The book also provides a critical re-assessment of the study of pragmatics within SLA. It has largely been neglected to date that L2 pragmatic knowledge includes more than the sociopragmatic and pragmalinguistic abilities for understanding and performing speech acts. Thus, the book argues for an extension of the scope of inquiry in interlanguage pragmatics beyond the cross-cultural investigation of speech acts. It also discusses pedagogical implications for foreign language teaching and will be of interest to applied linguists and SLA researchers, language teachers and curriculum designers.

The mechanics of closure, exhibited by ice tunnels, can be understood by considering the ice as a viscous solid. The viscous solid will flow, when subjected to a force, at a rate dependent on the magnitude of the force, the area of relief open for flow, and the apparent viscosity of the viscous solid. In the case of the ice tunnels, the force inducing the flow is the weight of the overburden; the area of relief open for flow is the tunnel opening; and apparent viscosity is the resistance to flow exhibited by the ice. The closure of a rectangular opening made in ice was measured. Maximum closure occurs at the center of unsupported roof, wall, or floor spans. The vertical closure rate decreases negligibly approximately 2% from the center of a room to approximately 6 ft from the wall. From the point about 6 ft from the wall to the wall, the closure rate decreases about 30%. Approximately 30% of vertical closure at the center of the span is due to flexure of the floor and roof. The remaining 70% is due to shortening of the wall height; the major portion of this wall closure occurs at the bottom of the wall. Over 80% of closure due to flexure of the floor and roof results from flexure of the floor. (Author).
