Modeling and managing separation for noise abatement arrival procedures
… to the growth of aviation. Advanced noise abatement approach and arrival procedures have been shown in previous studies and in limited implementation to be a cost effective means of achieving near- and medium-term noise reductions. Additionally, these procedures can be employed to reduce …

Wireless Dust Sensor Network for a Feedlot Dust Abatement Study
The mobilization of animals across Concentrated Animal Feeding Operations (CAFOs) generates large dust plumes causing visibility and human health issues. The ability to measure with many sampling points across a field and to have vertical measurements would aid in the characterization of dust …

Pollution Abatement Under Oligopoly With Free-Entry: Theory And Evidence
This research examines the role of the abatement subsidy as a potential environmental policy option under various scenarios. This is achieved through a combination of theoretical and empirical analyses. The main motivation for this work stems from the existing literature on the abatement subsidy …

Fundamental studies on copper zeolites for catalytic NO x abatement
… Catalytic Reduction (SCR) as the dominant NOx abatement technology in lean burn diesel engines. Standard SCR is a reaction of nitric oxide (NO) with ammonia (NH<sub>3</sub>), in the presence of oxygen (O<sub> 2</sub>) to form nitrogen (N<sub>2</sub>) and water (H<sub>2</sub>O). Copper …

Mechanisms governing the abatement of metal emissions from waste incineration.
A naturally occurring sorbent, kaolinite, is injected into a down-flow pilot scale combustor burning natural gas, doped with a surrogate metal containing waste (usually lead acetate). When sorbent is not introduced, lead vaporized in the flame ultimately forms a unimodal particle size distribution …

Market and bargaining approaches to nonpoint source pollution abatement problems
This research focuses upon the use of market incentives for environmental protection, with specific reference to nonpoint source pollution from agricultural land. The case when polluters contribute recursively rather than additively to environmental damages is investigated. While an optimal …

Sound Of “Di” Police: Community Policing and Crime Abatement in Post-Colonial Jamaica
<p><strong>Abstract</strong></p> <p>In 2007, the third largest island in the Caribbean, Jamaica, implemented a policing strategy known as community policing. With a population of just over 2.9 million, Jamaica is listed as number 10 out of 20 of the most dangerous places in the world. Additionally, …

A Data-Driven Approach to Departure and Arrival Noise Abatement Flight Procedure Development
An aircraft noise modeling framework is presented and used to perform a data-driven exploration of factors correlating with measured aircraft community noise and a model-based validation of the variables found to have the greatest noise impact. Aggregate departure and arrival noise and flight …

A Laboratory Investigation of Abatement of Airborne Diesel Particulate Matter Using Water Droplets
The term diesel particulate matter (DPM) is used to refer to the solid phase of diesel exhaust, which is mainly composed of elemental carbon and organic carbon. DPM is generally in the nano-size range (i.e., 10-1,000 nm). Occupational exposure is a health concern, with effects ranging from minor …
