The specific objectives are to (1) develop railroad energy efficiency models that describe differences... This study examines the impacts of the Clean Air Act Amendments of 1990 (CAAA90) on coal production and coal flows. The CAAA90 take a markedly different approach to pollution control from stationary sources when compared to past 'clean air' legislation. The new approach to limiting sulfur dioxide emissions... Public concern about hazardous materials, such as agricultural fertilizers, has steadily increased. Thus, North Dakota created Recommended Management Practices for The Primary and Secondary Containment of Fertilizers (RMP).
This study attempted to determine how compliance with RMP guidelines affects... The objectives of this projects were to: 1) develop a load test facility which can be used to perform static lateral load tests on model piles, 2) establish a prototype pile and a corresponding model pile, 3) design and implement the instrumentation for the model pile, 4) calibrate the model piles, 5)... The United States food processing industry is under increasing economic pressure to remain competitive internationally. Consequently, American firms are evolving from an adversarial to a close procurement relationship, with many adopting preferred supplier or partnership programs to decrease costs. A... The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent... This report covers the first year of a two-year study of unpaved roads. Maintenance and reconstruction models of unpaved roads are reviewed. These models are based upon empirical and mechanistic methods, and they have the objective of evaluating deterioration, roughness propagation parameters, scraping... This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different... This study examines consolidation of road services by local governments, and explores the optimal mix of roads for rural counties. A methodology for measuring economies in the provision of local road services is presented. This methodology is unique in two ways; 1) it better accounts for relevant variables... This report describes a study to evaluate the use of subgrade resilient modulus for the design of flexible pavements. The objectives of this initial study were to: a) investigate the relationship between resilient modulus and R-value, and b) develop a predictive equation for resilient modulus based on... |
