Brazing is where the filler and temperature is high enough that there i a significant amount of mixing of the base metal(s) to form a new alloy. Done right you can start off with a filler that is no longer present in the joint and a joint strength significantly higher than the filler material.
Yes, the base metal can 'melt' in the presence of fluxes (the filler can also act as a flux) that is a lower temperature than the base metal bulk melting temperature.
The whole system is a machine to make profit and keep pension funds ticking over.
Editors are seldom paid positions, similarly the peer review process is also not paid, researchers have to pay to submit papers and if they want the paper to be available to all they must pay extra, or it goes behind a pay wall.
The issue of fraudulent and or poor quality papers means a vast number of academics just do not respond to requests to provide a peer review and yet the institutions actively push for them to generate as many papers as possible with no regard given to providing peer review.
Many editors at the 'higher end' journals will ignore many papers that do not have someone significant on the author list or are submitted by an institution or country that does not meet their ideals, either ignoring or selecting for 'third world' depending on the field.
They will have charge in them, as part of the manufacturing process is to apply charge to form the surfaces (chemistry / texture) of the plates after initial assembly. The article does not mention if this is nickel (NMC) of iron (LFP) Lithium cells, the latter do not suffer from thermal runaway due to damage.
Whilst the use of per-revolutionary units does irk, I'm more confused by the grid connection and dynamo being a big thing.
Thermal power plants use turbines, and they have the power take off and grid connection part sorted.
If you have lower power requirements then you just use an inverter (with efficiencies of >98% so minimal losses), what's the big thing here? Other than replacing steam with CO2 which apparently provides some advantages in operational efficiencies. This is the second article discussing 'Sandia' does a relative work there? I've never come across the institution? before.
-> Thank you for confirming my point. I wrote that scientists are not always right. What a pity that the first groups of scientists who said such and such was safe can't be force fed the excrement they created.
Thalidomide is safe to those taking it (people still take it to treat leprosy), however it is not safe for fetus at a certain developmental point. Now how many pregnant women do you think were in the initial drug trials? same number as are in pretty much all drug trials - zero.
There is never zero risk, and sometimes the consequences are horrendous, but new information comes to light and conclusions change.
Slavery has not been completely abolished, it is still allowed for prisoners, hence the large numbers of such low cost workers.
"Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction"
No, you provide your evidence and references, if you are an expert.
This is a standard method / trick used by various virulent political parties and conspiracy theorists. The argument goes that if you disagree with them, then you should be able to spout chapter and verse of references to support your view. But in their case they will not say, X and Y because of this and this reference, because in that way they can easily be refuted.
Their aim here is to get you to provide references to the negative and then pick and argue for you to provide more against a particular part that they identify as incorrect.
The second objective is to get the less credulous to search for 'bellingcat is bad' and then start digging through the latrine of conspiracy theories.
So [The Chinese team developed an apparatus, dubbed Jiuzhang, that consists of a laser, mirrors, prisms, and photon detectors. The group reported that they achieved a sampling rate that's "~1014 faster than using the state-of-the-art simulation strategy and supercomputers."]
They built an experiment and were able to take measurments 10^14 time faster than simulating the physics in a computer. It is unclear what is new about this state of affairs, this is why most groups use experiments for this type of reaserch, rather than simulations.
Most americans think that slave labour was abolished by the 13th amendment. In actual fact by convicting someone you can then use them as slaves; "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction."
hmm, I wonder why there are so many people in jails? /sarcasm
Thre is enough information out there in research papers and company product documentation in combination with open source FEA tools to allow someone to make an engineering approximation of the mass, strength / stiffness and velocity required to breach any given structure. The redaction just weeds out the less competent.
