According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, inc...
Some of them make it into our upper atmosphere, where they collide with atoms—with oxygen and nitrogen atoms. This collision causes the atoms to light up, to glow… different types of atoms glowing different colors. And this is what’s happening when we’re seeing an aurora. ...
Dark red, brown, or black period blood is typically red blood that has reacted with oxygen Talk to your healthcare provider if you have grayish or pink watery discharge, as this could be a sign of an infection or something more serious ...
While oxygen is essential to life itself, oxidation is the “dark side” of oxygen that most people don’t know about. Oxygen is chemically reactive and under normal biochemical reactions, can become unstable. It oxidizes neighboring molecules, causing them to be unstable. This is the same proc...
Another factor is that during large solar storms our atmosphere actually increases in size due to heating, allowing the oxygen to rise to higher altitudes and therefore be seen reacting over larger areas. The equinox periods are proven best for northern lights chances Solar storms occur more ...
When merged with controlled amounts of oxygen, the process produces syngas, a combination of hydrogen and carbon monoxide that can be used for heat, electricity, and transportation through biofuel. Biomass is the only renewable energy source that can be converted into liquid biofuels, elevating it...
Nitrogen is more common in the atmosphere than oxygen on Earth, but oxygen keeps us alive. On Earth, all the land is on tectonic planes constantly moving. They move so slowly that you do not notice. Sometimes, the movement causes an earthquake when you feel the Earth move. Earthquakes can...
There is a layer of oxygen, nitrogen, carbon dioxide, and other gases that surround the Earth which we call the atmosphere, i.e., the air. The hydrosphere This part includes all the bodies of water on our planet such as the oceans, rivers, lakes, and polar ice. It also includes cloud...
Heat radiates off of the dark roofs, and water rushes over the hard, hopefully impermeable surfaces. Yet, there is a new trend that breaks up the monotony of common roofs: the green roof. Long popular in Europe, green rooftops have begun to appeal to homeowners, businesses and even ...
