We examined the immediate and long-term impacts of military aircraft noise exposure on noise-induced hearing loss (NIHL) in fighter pilots and ground staff. We recruited 40 pilots, 40 ground staff, and 136 age-matched controls; all participants underwent hearing tests, including conventional pure-tone audiometry (PTA) (0.25–8.0 kHz), extended high-frequency (EHF) audiometry (9.0–18.0 kHz), and distortion-product otoacoustic emission (DPOAE) as a recent reference. A subsequent hearing test immediately after flight-mission noise exposure was requested. The results revealed higher recent hearing

This paper proposes an unsupervised multi-exposure image fusion (MEF) method via contrastive learning, termed as MEF-CL. It breaks exposure limits and performance bottleneck faced by existing methods. MEF-CL firstly designs similarity constraints to preserve contents in source images. It eliminates the need for ground truth (actually not exist and created artificially) and thus avoids negative impacts of inappropriate ground truth on performance and generalization. Moreover, we explore a latent feature space and apply contrastive learning in this space to guide fused image to approximate norma

An assessment of the risk of illness associated with Escherichia coli O157:H7 in ground beef was drafted in 2001. The exposure assessment considers farm, slaughter, and preparation factors that influence the likelihood of humans consuming ground beef servings containing E. coli O157:H7 and the number of cells in a contaminated serving. Apparent seasonal differences in prevalence of cattle infected with E. coli O157:H7 corresponded to seasonal differences in human exposure. The model predicts that on average 0.018% of servings consumed during June through September and 0.007% of servings consum

High figure-ground contrast usually results in more positive evaluations of visual stimuli. This may either reflect that high figure-ground contrast per se is a desirable attribute or that this attribute facilitates fluent processing. In the latter case, the influence of high figure-ground contrast should be most pronounced under short exposure times, that is, under conditions where the facilitative influence on perceptual fluency is most pronounced. Supporting this hypothesis, ratings of the prettiness of visual stimuli increased with figure-ground contrast under short exposure times (.3, 1,

The paper makes an analysis of the selected location and feasibility of the exposure test ground in the real marine environment, and the endurance test of the FRP- reinforced concrete built-up beam has been carried out on the exposure test ground. After 6 month and 12 month’s exposure test, the beams' mechanic performance and the chloride ion content in different depths have been determined. The results show that after the exposure test, the beams' ultimate capacity has been greatly decreased to a certain extent, and the FRP board can effectively prevent chloride from penetrating.

Named storms can cause substantial impacts on the habitat and reproductive output of threatened species, such as marine turtles. To determine the impacts of named storms on marine turtles and inform management, it is necessary to determine the exposure of marine turtle nesting grounds to recent storm activities. To address this, remote sensing information of named storm tracks coupled with nesting ground data were used to investigate the temporal and spatial overlap between nesting grounds for four species of marine turtles in the continental United States of America.

Noise exposure is one of the most common hazards in the work force. There are multiple occupations that experience large amounts of noise exposure to its employees on a regular basis. Flight ground crews and flight maintenance personnel are among the nosiest jobs that exist. Despite the mandatory hearing protection requirements for a job of this caliber, there still remains a chance of an over exposure to noise. Most of the exposure comes from the different types of loud repair equipment and tools, but the greatest exposure comes from a jet engine that can reach 140 decibels. Flight maintenanc

The health impact of environmental hazards can differ between populations. These differences arise from sensitivity to hazards, disparity in exposure to hazards and a combination of both. Sensitivity is due to a range of factors including higher rates of underlying illness, genetic factors, poor access to health care, or lower socioeconomic status (SES). Spatial distribution of exposure gives rise to disparities in exposure which can lead to higher exposure among people of lower SES. Combining sensitivity and higher exposure compounds the effects of environmental hazards. This is known as envi

AbstractThe performance of adaptation measures depends on their robustness against various possible futures, with varying climate change impacts. Such impacts are driven by both climatic as well as non-climatic drivers. Risk dynamics are then important, as the avoided risk will determine the benefits of adaptation actions. It is argued that the integration of information on changing exposure and vulnerability is needed to make projections of future climate risk more realistic. In addition, many impact and vulnerability studies have used a top-down rather a technical approach. Whether adaptatio

Abstract The model for the degradation of the containers for nuclear waste includes three modes of corrosion, namely general corrosion, localized corrosion and environmentally assisted cracking (EAC). The objective of the current research was to quantify the susceptibility of five nickel alloys to EAC in several environmental conditions with varying solution composition, temperature and electrochemical potential. These alloys included: Alloy 22 (N06022), Alloy C-4 (N06455), Alloy 625 (N06625), Alloy G-3 (N06985) and Alloy 825 (N08825). The susceptibility to EAC was evaluated using constant def

Natural hazard threats occur in areas of the built environment where buildings, people, and related financial assets are exposed to the physical effects of earth system processes that have a potential to cause damage, injuries, losses, and related socioeconomic disruption. As cities, towns, and villages continue to expand and densify in response to the pressures of urban growth and development, so too do the levels of exposure and susceptibility to natural hazard threat. While our understanding of natural hazard processes has increased significantly over the last few decades, the ability to as

A set of experiments was conducted to expose different types of energized electrical cords for lamps, office equipment, and appliances to a developing room fire exposure. All of the cords were positioned on the floor and arranged in a manner to receive a similar thermal exposure. Six types of cords commonly used as power supply cords, extension cords, and as part of residential electrical wiring systems were chosen for the experiments. The non-metallic sheathed cables (NMB) typically found in residential electrical branch wiring were included to provide a link to previous research. The basic t

Environmental RNA (eRNA) is gaining ground as an environmental monitoring and assessment tool. Whereas environmental DNA is mainly utilized for species detection, and sometimes population size estimation, eRNA potentially provides additional scales or classes of inference. eRNA’s comparatively more rapid signal decay rates provide narrower temporal windows for species presence, while detection of messenger RNAs or other cell regulatory RNAs in environmental samples could provide evidence of genomic responses to environmental stressors. We tested select environmental messenger RNAs (e-mRNAs) of

Liquid pipeline companies operate a number of different facilities, such as pump stations, that are part of the transport stream of hazardous liquids. Many of these facilities are typically unmanned and have a number of sources (e.g., flanges, valves, tanks, etc.) that can leak. The consequences of such a leak are heightened as the amount of time passes until the leak is detected. There is a need for a technology (or group of technologies) to be deployed at such sites to autonomously detect and raise an alarm in the event of a leak. A project was conducted to identify and evaluate (on paper) p

Previous FSRI led research projects have focused on examining the fire environment with regards to current building construction methods, synthetic fuel loading, and best-practices in firefighting strategies and tactics. More than 50 experiments have been previously conducted utilizing furniture to produce vent-limited fire conditions, replicating the residential fire environment, and studying the methods of horizontal ventilation, vertical ventilation, and positive pressure attack. Tactical considerations generated from the research are intended to provide fire departments with information to

The goal of this study was to review the available literature to develop a quantitative description of the thermal conditions firefighters and their equipment are exposed to in a structural fire environment. The thermal exposure from the modern fire environment was characterized through the review of fire research studies and fire-ground incidents that provided insight and data to develop a range of quantification. This information was compared with existing standards for firefighting protective equipment to generate a sense of the gap between known information and the need for improved unders

As research continues into how fire department interventions affect fire dynamics in the modern fire environment, questions continue to arise on the impact and implications of interior versus exterior fire attack on both firefighter safety and occupant survivability. Previous research into various types of fire ground ventilation, flow paths, and exterior fire streams has provided the fire service with an increased understanding of fire dynamics. However, in some instances, the information from the studies did not support current, experience-based practices. This gap between the research to da
