3 years later I am still not clear on what types of cells in the body does the mRNA enter to produce the spike protein? I think you said the entire cell that produces the protein, not just the protein itself, gets destroyed by the immune system.
One has to be very skeptical watching this video, for what it avoids discussing as well as for basic errors. It comes across as a pitch for a grant funding sponsor, more than educational. The presented admits he made a most basic error of fact, as to HCl vs H2SO4. He does not mention that most LiIon batteries are thin film, either rolled as in 14500 or 18650 cells, or folded on rectangular thin flat packs. Only in Li (usually not LiIon) button cells of very low current capacity is a radial center membrane structure common. The comparison only with Tesla 21700 cells is telling, that this isn't about battery tech in general, but a pitch for a focused project. 21700 cells are rarely sold stand alone for flashlights or electronics. 1500 cycles is a quality spec, and 260 WHr equates to roughtly 6,000 mAHr, though that's hard to compare to common 18650's since eBay and ScAmazon have prolific spec fraud. (6 AH is more typical of 26650's, less common). The other two issues notably absent from this video are self discharge, and chemical ESR equivalent, or Equivalent Series Resistance. Those are huge factors in batteries that may alternately sit for extended periods, or power high peak load devices, be they power tools or cars. Resistive conductors like graphene, versus metallic electrodes as part of a battery process or to connect other chemical elements, are big deal issues. In a less detailed video as to chemistry, it might be easy to dismiss ignoring those as an attempt to simplify, but this goes into more detail over molecular chemistry, while ignoring those elephants behind the curtain. ESR of course equates to heat or ability to limit it, potential venting, and potential explosions or fires, and needs for charge-discharge smart management, or restricted current rates. Tesla quality and honesty of spec's is so high most of us likely have seen their car fires, as well as heard about a certain airplane model that was grounded until it was redesigned. Or heard about how useful ScAmazon's extreme legal budget is, to intimidate state AG's from fraud prosecutions, or run around people whose homes were burned down by reckless indifference to safe battery and related circuit designs. Ooops. Maybe literacy in more complex aspects of these issues matter? And some way to shut down predators who lie and cause serious hazards, and damages to consumer victims? This video does cover some useful info and ideas. However, it'd fail most peer reviews, as it's devious and evasive in how it reveals a conflict of interest that could be cited up front directly. It also focuses on select niche conditions and comparisons, while avoiding related core issues. That could be stated clearly up front, rather than leave users wondering if it's intended as deception by omission, or just careless presentation?
6:26 This frequency actually is not in the range of music, and is actually above the range of human hearing. The way some tesla coils play music is by switching the 20kHz signal on and off at a much slower frequency (e.g., like 440 Hz).
I am new to the nuclear industry. I am incredibly appreciative of this professor. His ability to teach complex subjects in a fun and insightful way is amazing! Thank you!
This is how Mr Viktor Nemkov, the deputy principal of a school in southern Belarus, experienced those crucial days in 1986. Well-worth a read: May 1. There are some rumours that something had happened at the Chernobyl nuclear power plant in Ukraine, but there was no official information. May 2. At news time on television, we were all in front of the TV set. And what do we see? Footage of the Chernobyl nuclear power plant shot from a helicopter, I don't know in which year. They explained that nothing had happened, that the plant was functioning perfectly, and that the alarm in the foreign press was just enemy propaganda. At night, I turned on the radio and found the Voice of America station (this was prohibited in the USSR and classified as "anti-Soviet activity"). I learned that there had been an explosion at the fourth unit of the Chernobyl nuclear power plant and that it was completely destroyed. May 3. The national holiday "Victory Day" on May 9 was approaching. Our school had to prepare the sports part of the celebration. Approximately 1,200 children aged 10 to 16 participated. It was very hot. Many children felt unwell; some fainted. The nurse took care of them, and we continued rehearsing. You have to be born in the Soviet Union to understand what we were doing. When I recall those days, my cheeks burn with shame every time. May 4. After 5 or 6 children fainted during rehearsal, I couldn't take it anymore and called the regional party committee (the principal had refused to call). I was bluntly told that the issue was not my concern, that I had to follow orders without question, and that I should not forget about party discipline. Then, I understood why the principal didn't want to make the phone call. May 5. Gorbachev, the General Secretary of the Communist Party of the Soviet Union, appeared on television. Gorbachev declared that a breakdown had occurred at the Chernobyl nuclear plant, that necessary measures were being taken, that the plant was still operational, and that there was no danger. He again repeated accusations that journalists were seeking sensationalism, etc. However, he did not mention that the population within a 30 km radius of Chernobyl had already been evacuated, nor did he mention that firefighters who had arrived first at the site of the explosion were already beginning to die. Meanwhile, school staff and students continued training and rehearsing in the schoolyard despite these issues. May 6. We finally received a telephone message from the city council ordering us to seal the windows in the classrooms and hallways and to not allow students to go outside during breaks. However, we had already received radioactive iodine in its highest concentrations during the first 7 days after the explosion. Thus, locked in our classrooms, we continued the lessons for two more weeks although rumours circulated that the city's party leaders had already evacuated their children to the northern part of the country. May 24. All our students were boarded onto trains that had arrived to transport them to different parts of Russia. Simultaneously, more than 10,000 people (children with their parents) crowded the railway station. Initially, everything proceeded in an orderly manner but as the first groups moved to board the wagons, chaos erupted. Despite the police deploying all their forces to the station, they could not control the situation. People listened only to us, the teachers. I will never forget that day because I have never seen so many desperate people in my life, looking at me with pain. I had never seen so many women and children crying. That day took a toll on my health and robbed me several years of life. Mr Nemkov died in 2009, aged 58 due to radiation exposure related illness barely 2 year after writing his testimony.
Good video on DU. I would prefer we were using it and spent fuel in breeders to make more energy instead of bullets. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ksBYsBy3GD8.html
15:55 ... Elon still saying he's already got a viable 18 wheeler truck -- which he does not -- just said so at his shareholder mega payday meeting. So, is the professor contradicting Elon? P.S. 18 wheelers can & do go millions of miles.
1:32 the electrolyte in a lead acid battery is sulphuric acid not hydrochloric,,, that is unlrss something recently changed and he's let it slip ; is his team working on something?
And THAT folks is how you convey a complex message to a general audience. The topic is still highly technical but this excellent presentation gives us the best chance of understanding the subject.
hinkley point c with 3,260 mw of power will be costing about usd 50 bn. in your calculation that would be ca. usd 15 bn for 1,000 mw of power … the newest finnish nuclear powerplant cost usd 11 bn for 1,600 mw of power - usd 7 bn for 1,000 mw of power …
PLEASE MAKE A VIDEO ABOUT USING WASTE U238 FROM PRESSURIZED LIGHT WATER REACTORS IN HEAVY WATER REACTORS AND PLEASE MENTION IF IT IS COST EFFECTIVE TO IT. INDIAs EX- TOP NUCLEAR SCIENTEST SAYS IT IS SO.
Professor, with all respect I have a question; I'm asking to myself how a containment building can be sturdy enough to contain a 2,000 ton reactor lid blowing through the air.
I believe the egyptians were the greatest scientist ever they could pull electricy from the sky and they made the perimeter of the pyramids the speed of light
It's a well known information that the night shift had less experienced people and they've managed to drop the power level to 30 mwe instead of holding 700 mwe that was required for the experiment by the guidelines. The wrong button might be a satire but they indeed fucked up. They've made a lot of mistakes that led to the explosion. The reactor might not be safe and not as properly designed as the Western ones and more modern ones, but the operators fucked up big time that night.
Fukushima happened because of tsunami and earthquake (afaik). It was not even remotely as bad as the explosion in Chernobyl's reactor. They surely poisoned the ocean around but it didn't blow up the same way as Chernobyl.
Thank you for making these videos. The general public knows so little about these technologies that we all interact with every day. This helps us understand these, which is important!
