|March 25, 2010
Summary
Dust and debris clouds from explosions and vehicles show no consistent wavelength-dependent transmittance. Extinction coefficients were related between infrared and visible regions for specific conditions.
Area of Science:
- Atmospheric optics
- Environmental science
- Explosion dynamics
Background:
- Dust and debris clouds significantly impact visibility and light transmittance.
- Understanding transmittance properties is crucial for applications like remote sensing and military operations.
Purpose of the Study:
- To analyze transmittance through dust and debris clouds generated by explosions and vehicles.
- To determine the wavelength dependency of transmittance.
- To establish relationships between extinction coefficients in different spectral regions.
Main Methods:
- Analysis of transmittance measurements from 120 trials across five field tests.
- Statistical testing to assess wavelength dependency of transmittance reduction over time.
- Correlation analysis between extinction coefficients in IR and visible spectra.
Main Results:
- No consistent wavelength dependence was found for transmittance reduction in dust and debris clouds.
- Transmittance reduction levels did not significantly differ across various wavelengths.
- Relationships between extinction coefficients in infrared and visible regions were established for specific explosive types and soil conditions.
Conclusions:
- Wavelength independence is a key characteristic of transmittance through explosion-generated dust and debris.
- Established relationships between IR and visible extinction coefficients offer insights for modeling and prediction.
- Findings have implications for visibility assessment in dynamic environments.

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:17Radiation: Applications
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

01:27Microbes and Climate Change
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
01:17Passive Diffusion: Overview and Kinetics
Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
When administered orally, drugs establish a substantial concentration gradient between the gastrointestinal (GI) lumen and the bloodstream, expediting their diffusion into...

01:24Transmission of Pathogens
Pathogens spread from their reservoirs to susceptible hosts through three main routes: contact transmission, vehicle transmission, and vector transmission. Each route involves distinct mechanisms of transfer.Contact TransmissionThis category includes direct contact, indirect contact, and droplet transmission:Direct contact involves immediate physical interaction between individuals—such as a handshake—which can spread pathogens like Streptococcus pyogenes, the bacterium responsible for...
