Anything in the room that is not yellow appears to be in black and white. [link] [comments]  |

| Why is most of the ozone present in one small layer? Posted: 08 Jan 2021 03:15 AM PST Why is it that almost all the ozone is present in that one layer? While all the other gasses are mixed evenly throughout the atmosphere. I have tried Google Google this but I didn't get much. All I got was results telling me how ozone was formed, but nothing about why it is almost exclusively in one layer. [link] [comments]  |
| How much Corona Virus needs to be present for detection in local wastewater treatment systems? Posted: 07 Jan 2021 09:17 PM PST Our news outlets have reporting that traces of Corona virus have been detected in some cities wastewater. My Question is, how much of the virus would need to be present in the wastewater treatment system to be detected and how does that translate to potential infection rates in the community?

| What’s the reason for the difference in covid vs flu ICU admissions? Posted: 07 Jan 2021 03:58 PM PST Is the number of admissions to ICU, due to covid much higher than admission due to flu in previous years, because there is more people contracting covid than contract flu, or because covid is a worse illness to contract?

| Does Covid19 convalescent plasma treatment depend on the nucleocapsid antibody? Posted: 07 Jan 2021 05:24 PM PST This news article (https://www.azfamily.com/news/continuing_coverage/coronavirus_coverage/people-vaccinated-cant-donate-convalescent-plasma-after-donations-are-needed-now/article_7165b902-44b9-11eb-958a-0bbf419b8600.html) states that vaccine recipients aren't useful for convalescent plasma donation not because of the experimental vaccine disqualification, but because the treatment relies on the nucleocapsid antibodies:
Is that the case? If so, what drives the requirement and why would the vaccine work and this this not? [link] [comments]  |

| Where are the highest concentrations of capillaries in human skin? Posted: 07 Jan 2021 09:42 AM PST I'm experimenting with a homemade Photoplethysmogram device and I am getting different pulse strengths from different parts of my body. Supposedly it is the skin capillaries that impact how good the PPG signal is. From online sources, I know fingers, earlobes, foreheads, and toes supposedly have a lot of capillaries that are good for measuring, but this is not very descriptive. Interestingly I can't find any sort of diagram of the human body that shows this information. Follow-up questions: - Does skin capillary density vary from person to person? - For those that are familiar with PPG, is it actually capillary density that is impacting my readings, or is it something else?

| Where does all of the material that eventually covers artifacts come from? Posted: 06 Jan 2021 09:56 PM PST I understand the general concept behind stratification: The deeper an item is, the older is must be compared to items found closer to the surface. My question is: Where does all of that rock and dirt come from? It seems to me that if the diameter of the Earth was growing, then it would make sense that material would be laid down in an even layer around the world and would lead to the clear banding we see in the geological record. But isn't the Earth a closed system? New rock is only pushed out in lava flows and a small amount does come from outer space in the form of asteroids, but I have a hard time believing that is a significant amount. Places that are part of flood planes or other more direct forms of sedimentation totally would bury items rather quickly. What about other areas free from the actions of water? Thank you in advance for any replies. This question has been itching at the back of my mind for a long time. [link] [comments]  |
| How does Power Level work on my microwave? Posted: 06 Jan 2021 06:37 PM PST Is it really lower power or is it on/off periodically? Both? Something else? [link] [comments]  |
