Good day to all. A couple more questions... Is it known if a patient that survives this new virus, remains immune to it or can contract it later again ? What happens to donor antibodies on a blood transfusion into the recipient patient ? Die, stay or start renewal/multiplication ?

Thanks, gentlemen. Searched with not enough success... Is there any commercial/municipal radioactive treatment for potable water ? Seen it is done at some food packing factories, but the web mentions mostly the reverse, removal of radiation contaminants from water. And what would such ionizing irradiation get rid of in water ? How does the medicine industry purifies their water for manufacturing/research purposes ?

Hi all. I see the act of installing filters to improve drinking water a double edge sword. It may stop some microorganisms, minerals, debris, perhaps toxins from drinking. But right now and during all the time you are not serving a glass of filtered water, inside the filter there is a multitude of undesirables that were previously captured and held in, as intimate soup with the water for the next glass you will serve. Water that can be in a reasonably good condition being forced to pass trough the rotting filter accumulations. What are the alternatives ? What process to improve drinking water for better and more convincing methods that does not use filters ? Ultraviolet? Boiling? Chemicals? ...?

Thanks, Charon. Another stupid question... Assuming inventing the word "singlill" -or whatever you want- to refer to illnesses that are contracted only once; can persons who are cured from, or survive an "singlill" infection episode provide microbiologic basis or sample for a vaccine ? Like replication of chosen/picked antibodies by another host ?

Hi. Is there a proper term for the kind of illnesses that can be contracted only once as the body creates the correct antibody defenses ?

From Wikipedia about chloroquine: It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system.[5] It is available as a generic medication.[1] The wholesale cost in the developing world is about US$0.04.[6] In the United States, it costs about US$5.30 per dose.[1] Does not matter if cheap, will squeeze wallets no matter what :

Thanks, iNow. Depending on the interpretation of 'utensils' , sneezed-upon products arrived imported from China could complicate the entire global commerce and health with unexplainable origin 😒 That was a good link from an authority voice we should respect away from speculations and social nets.

Is it known if this virus is also disseminated by pets, clothing, utensils ?

Welcome. Am using bourbon as it is approved for internal and external use, cheaper and smoother than the camping type.

Cannot confirm, do not have the books myself. Perhaps from hundreds writing crap, some may guess it near right. A 2008 book : ========================================================================== A 1981 book: - Please delete if improper -

More worrying is hysteria + virus + wait until this point is in the past.

The original ancient quarantine was quaranta (40) days, not 14. No one knows the exact proven figures for the incubation of the new illnesses. Left to guess if it will work ? The ones you say are the major risk are the ones without detectable symptoms = the ones incubating for unknown lapses = Trojan horses = the ones being brought to the country ?

The corona virus spreading; there is no recommendation to prepare the body for a better chance to fight the illness. In lack of a vaccine, what medicines taken now have any chance of preventing/diminishing the roulette of contracting/getting infected from someone we come across ? The U.S. citizens overseas, with positive symptoms being transported risking spread of the illness, is that the right thing to do, to bring the infected to US soil for an unclear/unproven treatment ?

When any of you find a way to explain this in other words, please do. ----> https://scitechdaily.com/new-droplet-based-electricity-generator-a-drop-of-water-can-light-up-100-led-bulbs/

The coil magnetic strength is proportional from multiplying Amperes times turns. The force formula has d2 on denominator for the distance between the interacting magnetic poles (which can never be zero); then, the closer they are, the stronger the push (or pull)

Hi. Planning to extend coverage of the back yard with ~40mm high gravel for an area automobiles park. Already did a section using about 25 mm sized gravel; the quarry has finer sizes, like 12 and 8 mm. Which should provide better traction? There is a mild slope, like 5 degrees. Gravel goes on top of polyethilene film placed over the soil (to prevent weeds from poking trough).

Hi. Can you suggest which jobs of what branches will have less chance to be wiped out by artificial intelligence robots ? Please do not mention politician... 😧

Thanks. Mass times velocity to get the most distance. OK. On the wrong-here octopus biology, I guess the increasing muscular force and body mass of a growing specimen governs the jet orifice size to obtain greater propulsion. As a grown octopus does not keep the small jet youth orifice.

Hi. What is PVC natural color ? Is there a clear, transparent rigid true PVC? Not just named 'clear PVC pipe' as found in products. Is it pigmented usually white when manufacturing pipes or is it natural white ? ----> https://www.usplastic.com/catalog/default.aspx?catid=592&parentcatid=728&clickid=leftnav

Hello all. Squeezing with a fixed force a water filled bladder, water exiting trough a orifice causing underwater propulsion as a squid/octopus does. If the orifice is small, the jet exit velocity is faster and the time to deplete the bladder is longer. A larger jet exit orifice produces a slower jet velocity of larger mass for a shorter time until the bladder depletes. Which orifice provides more propulsion (as to reach further, not faster ?) How does nature selected the optimal orifice size for the octopus need ? Proportionally to the size/mass of the growing octopus ?

That is a great "wake-up, brain!" Thanks.

Hi all. A spear mass is 1 Kg. If gravity g is 9.81 m/s² on this planet, its weight is F=mg = 1 x 9.81 = 9.81 Newtons. Is that right so far ? That same spear of 1 Kg underwater weighs 5 Newtons. Does it mean that the acceleration of gravity is not exactly constant in this planet as it would be then, g = F/m = 5/9.81 = 0.51 m/s² because differs underwater, part of this same planet ?

😖 No way to find 1 inch lumber at Lowe's. Looked and asked the personnel there...🙄 Suspect will be the same at Home Depot, etc. The 'actual' labeling may not be at other stores.

In need to make a jig for manufacturing something, went to a (U.S.) Lowe's store. In the land ruled by medieval inches, cannot buy a ONE INCH wide/thick piece of wood. Told to buy something else and 'rip'/cut to needs. Tried also to buy a HALF inch plywood sheet... No such thing. There is one they CALL half inch, being actual 15/32" or something like that... The 'two by four' studs aren't even 1 1/2" x 3 1/2" x 96" if measured carefully. What is going/gone wrong here ? Why this habit of misleading ? Or is that the system went metric and kept in hiding from the public ? How is wood dimensions sold in Europe ? I know a few years ago, Lowe's lost some millions on a suit from mislabeling dimensions. Now they label as 'nominal' and 'real'...

Hi all. Comparing the nutritional value of a meal with protein, carbohydrates, lipids, vitamins and all the rest together, that was cooked with a microwave oven and one equal cooked with a convection, conduction method for cooking; should differ ? Is there a study about such, away from speculations ? Can different heat energy sources from radiant fire, microwaves, immersion in boiling, even concentrated solar radiation cookers or any other, alter nutrition or create more or less toxins ?
