This paper proposes a method for estimating emissions of carbon dioxide (CO2) and particulate matter (PM) from ships using Automatic Identification System (AIS) data. The method can be summarized in three steps : 1) capture of AIS data, 2) estimation of ships resistance, propulsion power, engine power and fuel consumption, 3) estimation of CO2 and PM emissions based on fuel consumption. The met...

The major concern with a recent study covering airborne particulate matter (PM) from cattle feeding facilities lies not within the research but with the conclusions drawn and much more with the distorted misrepresentations of those data that have been spread through the media. We will address this by briefly discussing three major points in the research and hopefully eliminate some of the confu...

Recent air quality legislation has placed increased pressure on agricultural producers in several states across the US. In particular, California removed the exemption for agricultural sources from air quality permitting in 2003. Through the use of inaccurate particulate matter emission factors, agricultural operations have been targeted as significant sources of particulate matter emissions. T...

Several collocated semicontinuous instruments measuring particulate matter with particle sizes < or =2.5 microm (PM2.5) sulfate (SO4(2-)) and nitrate (NO3-) were intercompared during two intensive field campaigns as part of the PM2.5 Technology Assessment and Characterization Study. The summer 2001 urban campaign in Queens, NY, and the summer 2002 rural campaign in upstate New York (Whiteface M...

SCOPE The major receptor for β(1-3)-glucans on immune cells is considered to be Dectin-1 receptor. Particulate β-glucans induce stronger immune responses than soluble β-glucans by clustering of Dectin-1 receptors. Here, it was hypothesized that activation of other pattern recognition receptors such as Toll-like receptor 4 (TLR4) can also contribute to enhanced activity of immune cells after exp...

Background: Particulate matter pollution has become a growing health concern over the past few decades globally. The problem is especially evident in China, where particulate matter levels prior to 2013 are publically unavailable. We conducted a systematic review of scientific literature that reported fine particulate matter (PM2.5) concentrations in different regions of China from 2005 to 2016...

The eruption of Mount St. Helens in Washington State on May 18th, 1980 resulted in a massive and unanticipated particulate air pollution shock. I use the incidence of the ash cloud fallout across Washington as a natural experiment to estimate the effect of a particulate shock on birth outcomes and infant mortality. I find that while there is no statistical effect on infant mortality, there were...

The spectral dependency of the particulate backscattering ratio is relevant in the fields of ocean color inversion, light field modeling, and inferring particle properties from optical measurements. Aside from theoretical predictions for spherical, homogeneous particles, we have very limited knowledge of the actual in situ spectral variability of the particulate backscattering ratio. This work ...

RIDGE PRESERVATION COMPARING THE CLINICAL AND HISTOLOGIC HEALING OF AN INTRASOCKET ALLOGRAFT VS. A FACIAL OVERLAY XENOGRAFT USING A BIORESORBABLE BARRIER MEMBRANE Evmenios Poulias, DDS September 17th, 2012 Aim. The efficacy of ridge preservation procedures using grafting materials and barrier membranes has been well established in the literature. However, the loss of horizontal width even with ...

The high efficiency of diesel engines, their low operating costs, high durability and reliability have provided them with a leadership role in the heavy-duty vehicle market. Recently, diesel engines also achieved a growing share of the light-duty vehicle market, especially in those areas where fuel costs are high. This trend of growth of the diesel market requires a careful evaluation of the re...
