"The particulate matter that's in this haze is significant because it does irritate the bronchioles, or the small tubes that go down into your lungs and connect to the alveoli, which are the sacs that allow you to breathe," Dr. Bob Lahita, director of the Institute for Autoimmune and Rh...
Aerosol instruments provide more informative engine exhaust particulate matter (PM) data than the gravimetric filter and solid particle number methods prescribed by regulations. Yet their lack of conformity to the regulatory methods can limit their acceptance for vehicle development. This article examines ...
During the burning process, a second column of flame is fired up in a secondary chamber to burn off any particles or dust in the air leaving the retort, in order to reduce emissions, smoke and odors. Some retorts also have a wet scrubber in the emissions stack that sprays a mist of w...
Put the nasal prongs (cannula) in your nose and breathe normally. If you are unsure of whether oxygen is flowing, you can test it by placing the nasal prongs (cannula) in a glass of water. If you see bubbles, the oxygen is flowing. ...
5. Put the spare tire on Start by aligning the holes on the wheel to the lug posts, then push the tire in place. Apply pressure to ensure the wheel is on as far as it will go, careful not to push too hard. Then you can add one lug nut at a time — go in a diagonal or st...
We use "standardized" urban or indoor dust particles, which allows us to compare results with those from other labs who might also be using these particles (although realistic particles taken straight from the air around us are also sometimes used). We then put them in an aerosol cloud that...
Aerosol scientists always suspected SARS-CoV-2 was airborne, so studying the virus inside an aerosol provided an opportunity to back those suspicions with evidence. Taking the work her lab was already doing with aerosols and the work her lab was also doing with the virus, Amaro put two and ...
We didn’t know if we had what it takes to get in there. But there was also this thrill and excitement for the opportunity. What an amazing opportunity for a new business with a new innovation to be able to put it in front of the Sharks and all the people that would watch the ...
Here’s how to put all of your newfound knowledge to use. Pay attention because I will quiz you (jk, but could you imagine?): STEP 0: Final “reset” wash Wash your hair with a sulfate-filled clarifying shampoo to remove all silicone buildup. Repeat this step any time you accidentally...
Air massesIn addition to aerosol number concentration, aerosol size and composition are essential attributes needed to adequately represent aerosol-cloud interactions (ACI) in models. As the nature of ACI varies enormously with environmental conditions, global-scale constraints on particle properties are ...
