6.3V is the standard voltage of a farm tractor battery --these vacuum tube heaters were designed to use them.
12.6V is two farm tractor batteries (one car battery), which is why our computer industry uses 12V for motherboards (12 volts - 0.6V reverse protection diode).
Early computer power supplies used voltage regulators that were designed for car radios, originally.
Farm tractors and cars switched from 6 volt to 12 volt at about the same time, and for the same reasons. However the old 6 volt farm tractors are still around and used for framing, while 6 volt cars are rare collectors items (even though there were more of them).
Some people in the auto industry want to double the voltage again (for efficiency and to reduce the weight/complexity requirements for all the wiring, especially in EVs) but the 12 volt standard is pretty entrenched.
(Note that I'm talking about the voltage used for everything outside of the internal engine/li-ion electrical systems, which already use higher voltages as needed.)
not even close. I'm not aware of a single vehicle still in production with a 6 volt battery system.
Many kick-start and pull-start engines do not have a specific voltage but may use an alternator wound with a number of different coils to produce different voltages.
….As part of a bank of batteries producing a higher voltage. I haven’t seen any 6v equipment manufactured for any engine based equipment larger than a couple of KW for a very, very long time (mid 1960s). Lower voltage means higher amperage means more weight, more cost, more heat, more failures. Objectively, the world would be a significantly better place if we had fully transitioned to 24v or higher (up to 48v anyway) much sooner than later.
Interestingly, micro-miniaturization has reversed the trend of higher voltage = higher efficiency, at least for computing.
yes, because the underlying cell voltage is much lower than that. Many 6 volt batteries still exist because they are used in series to make the desired voltage. They are easier to move around and transport when they aren't build as all the cells in one unit.
But don't 12V lead-acid batteries have a wide voltage range between charged (~14.5V) and discharged (~10V)? I don't think they would provide exactly 12.6V very often, or for very long.
The adjective form of nouns that refer to animals is usually singular when acting as adjectives (goose liver, dog food, rat race). So, it would be two horse asses. The preference for singular is likely to avoid confusion with the possessive form, which in this case would be missing an apostrophe or of for possession: two horses' asses or the asses of [those (specific / in context)] two horses.
This review describes investigations of specific topics that lie within the general subject of HSV1’s role in AD/dementia, published in the last couple of years. They include studies on the following: relationship of HSV1 to AD using neural stem cells; the apparent protective effects of treatment of HSV1 infection or of VZV infection with antivirals prior to the onset of dementia; the putative involvement of VZV in AD/dementia; the possible role of human herpes virus 6 (HHV6) in AD; the seemingly reduced risk of dementia after vaccination with diverse types of vaccine, and the association shown in some vaccine studies with reduced frequency of HSV1 reactivation; anti-HSV serum antibodies supporting the linkage of HSV1 in brain with AD in APOE-ε4 carriers, and the association between APOE and cognition, and association of APOE and infection with AD/dementia. The conclusions are that there is now overwhelming evidence for HSV1’s role—probably causal—in AD, when it is present in brain of APOE-ε4 carriers, and that further investigations should be made on possible prevention of the disease by vaccination, or by prolonged antiviral treatment of HSV1 infection in APOE-ε4 carriers, before disease onset.
The author of the publication suggests that herpes (HSV1, but also others) is a likely cause of dementia and Alzheimer’s. Especially in carriers of the APOE-4 gene.
Also speculates that taking antiviral treatments, even short courses, might delay or prevent the virus progressing from peripheral to central nervous system.
As naive as it may sound, start your own little health care facility, with physicians and individuals who see the problems that plague mainstream. The facility can be either be a secret or out in the sea, outside the jurisdiction of most governments. The rot in mainstream medicine (as with some other aspects of life) is so deep and entrenched that no amount of attempting to fix it by individuals (or even groups) will work.
I guess creating startups that offer polished ctDNA solutions or pressing local governments to make healthcare more streamlined, perhaps even with healthcare IT startups too.
The problem is that most healthcare systems are too fragmented and not geared towards prevention. Hence, one faces a huge uphill battle.
