The researchers caution that this was an initial scoping study, in which they had to rely on health data available for outdoor air particles.

«Exposure to larger air particles linked to increased risk of asthma in children.»

«Our primary goal was to figure out what's happening in houses that leads to higher air particle levels and, in turn, to unhealthy environments for kids,» said study coauthor John Bellettiere, a graduate student in the SDSU - UCSD Joint Doctoral Program in Public Health.

In further tests, researchers stimulated sensitive long hairs on the spider's legs and body — previously known to pick up near - field airflow and vibrations — which generated a response in the same neurons that fired after hearing distant sounds, providing evidence the hairs are likely detecting nanoscale air particles that become excited from a sound wave.

«Missing piece of air particle equation hiding in the walls.»

Because sound is nothing more than vibrating air particles, it should, in theory, be able to transmit energy.

And while it's being directed to your eye, it's passing through the atmosphere, which has air particles scattering light along that direction.

It ranks fourth for short - term air particle pollution and seventh for ozone.

«At levels that the EPA considers to be generally safe, we found an important effect of ambient air particles, which is one of many pollutants in the air, but an important one,» says study coauthor Gregory A. Wellenius, Sc.D., an assistant professor of community health at Brown University Medical School, in Providence, R.I. Wellenius collaborated with researchers at Beth Israel Deaconess Medical Center and the Harvard School of Public Health, both in Boston.

The porous structure of charcoal bamboo provides countless tiny holes that effectively absorb odors, moisture and polluted air particles like formaldehyde, ammonia, and benzene.

The mixture formation itself is also enhanced by turbulences at the edges and inside the cone - shaped spray; these suck air particles into the fuel spray, forming an optimally ignitable mixture.

A new study by the National Oceanic and Atmospheric Administration and the University of Colorado, Boulder shows that the amount of particulate emissions caused by commercial shipping is equal to about half of all the world's cars: The study's authors say that this is the first global estimate of air particle pollution based on direct measurement of emissions.

In California, exposure to these fine air particles is associated with up to 24,000 deaths every year, according to a 2009 study by the California Air Resources Board, the majority of them in highly populated areas such as the San Francisco Bay, the San Joaquin Valley and the Los Angeles air basins.

It's a good idea to dust your plant leaves every so often to ensure proper absorption of air particles and toxins.

Using publically available data about wind speed and water vapor flux from real - world atmospheric rivers over the Atlantic, the scientists created a computer model consisting of thousands of moving virtual air particles and found a close match between the complex swirls — the Lagrangian coherent structures — made by the air particles and the patterns made by the real atmospheric rivers.

The sound wave originates from the vibrating object, such as a vocal chord, and travels through the medium (such as air) causing all of the air particles to vibrate at the frequency of the vocal chord.

These air particles subsequently bump against air particles next to them and so forth, so the wave travels from air particle to air particle — all at the same frequency as the vibration of the violin string.

The air particles speed up, in other words their temperature increases, the hotter air is less dense than colder air above and hence moves up (convection).
