  1. Thanks, fellows. Seems there is some interesting truth in the technique.

     

    Would the use of borax instead of an antibiotic produce similar results ?

     

    What other compounds you suggest that embedded in paint or epoxy will prevent the growth/attachment of marine life to a hull; without contaminating the sea - I mean, would be effective when the organism erodes the paint and reaches the toxin; but the toxin would not be washed itself by the sea.

  2. Are all warm blooded animals regulated at 37 C ?

     

    Why 37 ? Why fever does not go beyond 42 C ? Is it at 42 C the sickening microorganisms are 'killed' by the body thermal rise defense ?

     

    In occasions with near 42 C fever, I have had allucinations, and after that, a relief/cured sensation. What goes on ? Did the fever actually killed the 'illness' ?

  3. Thanks.

    The explanation I received is that barnacles and algae footings/rootings do erode the epoxy surface to secure attachment, and is when they become in contact with the until-then-preserved, embedded, still active antibiotic.

     

    And done that way because the cost of currently available commercial anti-fouling coatings is too high for the service time they provide. The light, poor attachment of algae that occurs even with this treatment just washes away by itself with boat motion.

  4. Someone I know mixes eritromycin with clear epoxy and paints the hull of his boat, a kilo in 10 litres.

    Says lasts over 10 years, with nothing attaching/growing on it.

    Any compound that would have the same effect ? At my location, antibiotics are not sold freely.

     

    Don't know if 'equivalent' can be twisted towards some kind of poison that could be a marine life permanent danger. The confinement status of a non decaying killer/contaminant product in epoxy can be arguable, I understand.

  5. In case is of help to anyone; buying an 'unpleasant' brand of cigarrettes does diminish the smoking; if does not give you also a nasty throat infection* that forces to not smoke for at least several days.

    That can be used as an opportunity to stretch the days and hold on to a non-smoking future, or change then to yet another brand.

     

    I have stopped two or three times for a year or so; and now am back on a much less intensity; but just because I am bored at work breaks, and do not now what to replace the habit with.

    Smoking gives me nothing, no high, no relax, no nothing, no shit. Just a sensation while smoking that cannot feel later nor lasts. If someone comes up with a similar harmless thing to aspire it would be good to switch to.

     

    *Seen it happening several times. A change in brand nests some different kind of resident microbes on the throat that we have built no defenses against ¿?

  6. Hello John.

    I came across a related document that may get similar effects if the poor quality fresh water has some dissolved minerals or a pinch of table salt added; or increasing current or time :

    Mokele:

    Yes, no doubt filtering works, not questioning that. But I have a problem with filters in general; as they capture all the undesirable nasty microbes piling them up putrefacting on a layer against the filter wall.

    And the next day the water to be filtered is forced to pass through it. :-( ---Yes, change the filter after every use - :confused:

  7. Hello.

     

    Application of electrical current for just a second from an electrode in a metal pot should destroy most if not all life in its water instantaneously.

    Why is such procedure not exploited ? At least I do not know of it being used to disinfect water :confused: Or is it ?

     

    The typical action is to boil the water; with huge amount of power used.

  8. Since day one I can remember as kid, Venus has been at about the same location by 8pm; by west and at the ~same elevation I have seen it along the years.

     

    Am I wrong? Isn't Venus a planet and by orbiting the sun it should gradually change its location ?

  9. Hi.

    A program I have displays the elevation and azimuth of the sun in real time for a chosen location, updated every second.

    How can I tap into that data to perform other basic calculations, send to parallel port and display the results in another window simultaneously ?

     

    Am not good at all with compfusers...:-(

  10. Yes. That was it. :)

     

    ...And how can I obtain the azimuth and elevation vectors of the sun from the observer (sidereal?) time, date and coordinates ? Do I have to use some tables or there is a formula ?

  11. Been a long time since the university years, no books on hand, and with terminology in another language, this may be hard to explain/ask...

     

    From a fixed point of view, say the tip of your tv antenna at the roof;

     

    -The street hydrant is at a fixed direction; elevation and azimuth. Do not care about the distance.

     

    -The sun is at another direction; elevation and azimuth.

     

    How is the (bisectriz) bisecting vector elevation and azimuth calculated ? Simply sums divided by 2 ?

  12. The New Element - Governmentium (Gv)

     

    Recent hurricanes and gasoline issues are proof of the existence of a new chemical element. Research has led to the discovery of the heaviest element yet known to science. The new element, Governmentium (Gv), has one neutron, 25 assistant neutrons, 88 deputy neutrons and 198 assistant deputy neutrons, giving it an atomic mass of 312.

     

    These 312 particles are held together by forces called morons, which are surrounded by vast quantities of lepton-like particles called peons. Since Governmentium has no electrons, it is inert; however, it can be detected, because it impedes every reaction with which it comes into contact.

     

    A minute amount of Governmentium can cause a reaction that would normally take less than a second to anytime from four days to four years to complete. Governmentium has a normal half-life of two-four years; It does not decay, but instead undergoes a reorganization in which a portion of the assistant neutrons and deputy neutrons exchange places.

     

    In fact, Governmentium's mass will actually increase over time, since each reorganization will cause more morons to become neutrons, forming isodopes. This characteristic of moron promotion leads some scientists to believe that Governmentium is formed whenever morons reach a critical concentration.

     

    This hypothetical quantity is referred to as critical morass. When catalyzed with money, Governmentium becomes Administratium (Ad), an element that radiates just as much energy as Governmentium, since it has half as many peons but twice as many morons.

  13. Hi.

    What would be the vertical motion amplitude at 5 metres below surface for a seawave of 0,5m amplitude (1 metre peak to trough) at surface?

    There is some formulas at wiki but unsure how to translate them into what I want to know :confused:
