A discussion covers technical and regulatory challenges involved in addressing fugitive sources in terms of emission quantification, transport modeling and impact assessment, with emphasis on measurement and modeling of emissions from upstream oil and gas production, industrial flares, and fugitive dust sources. This is an abstract of a paper presented at the 106th AWMA Annual Conference and Exhibition (Chicago, IL 6/25-28/2013).

Concerns of infectious disease outbreaks have recently reached the forefront of global security issues and resulted in new engagements among foreign science advisors, host country scientists, and officials. There are lessons to be learned from the numerous organizations working in global regions of endemic disease who are building capacity to survey pathogens and prevent and contain epidemics. Working with foreign scientists, health professionals, and administrators can be challenging; building partnerships based on respect and mutual trust is key to achieve effective change. Engendering ownership, working towards mutual success, paying close attention to cultural norms and the local regulatory climate, close collaboration with other stakeholders, and imaginative problem solving all contribute to mission success. © 2015 Horn.

Across the nation, open sources account for the majority of directly emitted PM10, and for emissions of gases, e.g., NH3, biogenic species, and other pollutants of regulatory concern. The use of vehicle-mounted continuous pollutant concentration monitors for mapping at "ground level" the locations and lateral structures of plumes crossing roadways downwind of emission release points was studied. One of the key ad vantages of this approach is the much lower cost of implementation in comparison with other monitoring strategies. This is an abstract of a paper presented at the 105th AWMA Annual Conference and Exhibition (San Antonio, TX 6/19-22/2012).

Amid changing attitudes about the environment and emerging sustainability concerns in the late 1960s and 1970s, countries around the world began regulating multiple aspects of solid and hazardous wastes. Initial regulations and those occurring since all share the broader goal of curbing waste generation, especially that of hazardous wastes; but with few signs of progress. Using an input-output accounting framework that focuses on the domestic economy, data on the economy and hazardous waste generation are combined to provide a more complete picture of hazardous waste generation in the United States. The framework developed in this paper can be used to inform decisionmakers of the current state of the "hazardous waste economy" and can also be extended to account for other types of environmental factors. © 2012 Elsevier B.V.

The safety effects of horizontal curves and grades on highways have been quantified separately, but it is not currently known whether or how the safety performance of horizontal curves interacts with that of grades. Although the first edition of the AASHTO Highway Safety Manual provides crash modification factors for the safety effects of horizontal curvature and percent grade on rural two-lane highways, the manual does not have a method for accounting for the interactions between these effects. In other words, in the Highway Safety Manual procedures for rural two-lane highways, the safety effect of a horizontal curve is the same whether the curve is located on a level roadway, a straight grade, or a vertical curve. Similarly, the safety effect of a straight grade is the same whether it is located on a tangent roadway or horizontal curve. Researchers have always supposed that there are interactions between the safety effects of horizontal and vertical alignments, but these interactions have not been demonstrated in a form useful for safety prediction. The results of research undertaken to quantify the safety effects of five types of horizontal and vertical alignment combinations based on Highway Safety Information System data and crash records from 2003 to 2008 in Washington State are summarized. The outcome is a set of safety prediction models for fatal and injury and property-damage-only crashes. To present the results in a form suitable for incorporation into the Highway Safety Manual, crash modification factors representing safety performance relative to level tangents were developed from these models for each of the five combinations.

A particle collector for collecting biological material using electrostatic precipitator (ESP) technology including a removable ESP collection tube having an electrode wire suspended therein, a high voltage power supply coupled to the electrode wire for generating an ionization field within the collection tube causing smaller particles entering the collection tube to precipitate onto the walls of the collection tube, electronics including a microcontroller for controlling the operation of the collector, and a housing assembly for housing the collection tube, the high voltage power supply and the electronics. Some embodiments include an interlock system for disabling high voltage to the electrode wire if certain system parameters are not met, a static discharge mechanism for dissipating excess electrostatic charge which may accumulate on the collection tube during operation, and an altitude adjustment mechanism for adjusting the amount of high voltage supplied to the electrode wire based upon the altitude at which the collector is being used. A portable hand-held embodiment of the particle collector is also disclosed.

A method of culturing fastidious bacteria where a conditioned cell culture medium is prepared in which eukaryotic cells have been cultured, but where the medium is substantially free of the cultured cells. Fastidious bacteria are cultured in the medium. The conditioned cell culture medium can contain secreted factors from the cells. These factors promote the growth of the fastidious bacteria. The fastidious bacterial culture is maintained for a time period sufficient for the fastidious bacteria to multiply. The fastidious bacteria are analyzed using PCR, DNA sequencing or microbiology characterization.

Phosgene Oxime (CX), an urticant or nettle agent categorized as a vesicant, is a potential chemical warfare and terrorist weapon. Its exposure can result in widespread and devastating effects including high mortality due to its fast penetration and ability to cause immediate severe cutaneous injury. It is one of the least studied chemical warfare agents with no effective therapy available. Thus, our goal was to examine the acute effects of CX following its cutaneous exposure in SKH-1 hairless mice to help establish a relevant injury model. Results from our study show that topical cutaneous exposure to CX vapor causes blanching of exposed skin with an erythematous ring, necrosis, edema, mild urticaria and erythema within minutes after exposure out to 8h post-exposure. These clinical skin manifestations were accompanied with increases in skin thickness, apoptotic cell death, mast cell degranulation, myeloperoxidase activity indicating neutrophil infiltration, p53 phosphorylation and accumulation, and an increase in COX-2 and TNF levels. Topical CX-exposure also resulted in the dilatation of the peripheral vessels with a robust increase in RBCs in vessels of the liver, spleen, kidney, lungs and heart tissues. These events could cause a drop in blood pressure leading to shock, hypoxia and death. Together, this is the first report on effects of CX cutaneous exposure, which could help design further comprehensive studies evaluating the acute and chronic skin injuries from CX topical exposure and elucidate the related mechanism of action to aid in the identification of therapeutic targets and mitigation of injury.
