Leaded gas allowed the octane level to be increased and eliminated knock, which was a widespread problem in engines at the time. Since then Ethanol has mostly taken over from Leaded fuel, although it’s still sold for off-road equipment and aircraft.
Lead is bad for humans because it interferes with numerous enzymes inside the cells of these organs. This results in symptoms such as muscle and joint aches as well as constipation and overall fatigue. It damages our brains by interfering with how brain cells send messages and communicate
What is the biggest source of lead? Homes near busy streets may have higher levels of lead in the soil. Today, lead still comes from metal smelting, battery manufacturing, and other factories that use lead. This lead gets into the air and then mixes with the soil near homes, especially if the home is near one of these sources.
What is lead used for?
Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.
A: "Lead" has two specific meanings. As a noun, lead (pronounced like "bread") is a metallic element. It's labeled on the periodic table as "Pb" and sometimes found in really old paint. The U.S. government banned lead paint in 1978.
Leaded gasoline In December 1921, while working under the direction of Charles Kettering at Dayton Research Laboratories, a subsidiary of General Motors, Midgley discovered that the addition of tetraethyllead (TEL) to gasoline prevented "knocking" in internal combustion engines. Known for: Leaded petrol; CFCs Died: November 2, 1944 (aged 55); Worthington, Ohio
Who invented the two deadliest substance of the 20th century?
Thomas Midgely Jr. One Man Invented Two of the Deadliest Substances of the 20th Century. Thomas Midgely Jr. had, in the words of author Bill Bryson, “an instinct for the regrettable that was almost uncanny.” He is single-handedly responsible for creating two of the most destructive compounds in American history
Who discovered leaded gasoline? Thomas Midgley, Jr. (May 18, 1889 - November 2, 1944), an American chemist, developed the tetraethyl lead (TEL) additive for gasoline and chlorofluorocarbons (CFCs) and held over a hundred patents.
the bitter reality of today's world is, you need 2 things to survive here.. Power or money, even karma won't work if you don't have any one of them. The reality is people are double faced..We talk about the cruelty of world at home, among each other, on social media and do the same cruelties. Bad things are the truth of this world and good has now become just an exception.
when i heard this story of that poor lady in the foot path... i got.....
Got goosebumps…
I can't even imagine the pain they go through…unbearable.
Just because the lady (and that missing girl) are poor…and not privileged enough…doesn't mean their life doesn't count. They are equally valid. In fact, on the contrary, they need even more help since they have nowhere else to go for help and no one who can support them.
As much as I see the limitations from the police side to find the girl (due to a... lack of photograph)…if they actually wanted to help, they should've and could've found a way. Not just as a police, but as a normal person.
(Simply because there s no photo of the girl, the mother is seperated from her kid forever.)
but humanity is totally absent.
Depressing to hear of such incidents. We have the police force and courts and all systems in place …. but everything has rusted away and very creaky due to wrong practices and priorities by those in control and power! The ordinary man is so helpless without any “working" support system and has no one to turn to. High time we worked out a change for the better.
I dreamed I was walking along the beach with the Lord,(jesus) and Across the sky flashed scenes from my life. For each scene I noticed two sets of footprints in the sand; One belonged to me, and the other to the Lord. When the last scene of my life flashed before us, I looked back at the footprints in the
the sky flashed scenes from my life. For each scene I noticed two sets of footprints in the sand; One belonged to me, and the other to the Lord. When the last scene of my life flashed before us, I looked back at the footprints in the sand. I noticed that many times along the path of my life, There was only one set of footprints.
I also noticed that it happened at the very lowest and saddest times in my life This really bothered me, and I questioned the Lord about it. "Lord, you said that once I decided to follow you, You would walk with me all the way; But I have noticed that during the most troublesome times in my life, There is only one set of footprints. I don't understand why in times when I needed you the most, you should leave me.
The Lord replied, "My precious child. I love you, and I would never, ever leave you during your sufferings.... when you seen just one set of foot prints.... it was then .. that... i carried you... that is.... Jesus.
