Thanks, studiot, for your knowledge and dedication to explain and share it.

Why flexible ? The generator should run at its suggested rpm. Use gearing. You need speed. ----> http://www.scienceforums.net/topic/65768-paddle-wheel-calculations-please/ ----> https://groups.google.com/forum/?hl=en#!searchin/sci.physics/%22how$20to$20calculate$20the$20force%22/sci.physics/iM108GzW6tI/KbDIS008fCgJ

Hi. A glue in its container, stays useable until applied, has no exposure to air or whatever makes it 'hard'. Closing the container after use, keeps it useable for still a long time. If the application is between two surfaces, were the glue is confined to similar 'air tight' conditions as it was in the container, it usually hardens as supposed to. What differs in both conditions, inside the container and inside joined impermeable parts ?

Hi. Instead of flame powered, an electric heating element. How does it compare to a plain AC household electric refrigerator, say one that consumes 250 Watts x 16 hours every day. (4000 Watthour) A 250 watt heating element attached to an absorption refrigerator, would have a reasonable household performance ?

Could this often ignored, abundant metal provide an energy source as hydrogen with economical sense ? Is its production too much energy demanding as to discard its potential ? Is there a specific voltage or method that could collect only calcium ions from seawater without other cathodic deposits ?

If seawater is ingested, read somewhere it works as a poison. Well, the poisonous effects have to manifest at a certain volume (that I do not know) ingested. Let's assume drinking a litre in 24 hours is really bad for the body. Perhaps lethal. If only the sodium chloride is removed from seawater, leaving all other natural elements present in seawater; will drinking a litre in 24 hours still be poisonous ? (Assume no bio-microorganisms presence in any case)

Very old thread, resurrected as I found something pertinent claiming an electronic method for desalination. - The use of the term "mediated" -what does it mean ? - If works in such small scale, what could prevent from making bigger ones instead of paralleling many tiny ones ? ----> http://www.ideaconnection.com/new-inventions/waterchip-provides-cheap-effective-desalination-08434.html

Aquarium hose tightly fitted in a drilled drain hole does it too. If the top hose end is inside a piece of sponge, avoids clogging.

Are impressive; looking for a formula to prepare such, the web shows to boil reduce corn syrup. Seems too simple. Anyone knows how to prepare it ? Seen fly trap ribbons formulas, with weaker glue based on honey/sugar. Stolen from somewhere... "Mix 1 qt. corn syrup mix and 1 qt. water in a pan. Bring the mixture to a boil. This will create a non drying sticky paste." Does the boil changes the chemical stickyness or just concentrates it by reducing ? If only concentrates it, why add water to start ?

Greg: That stair setup is ideal for cascading irrigation from the top planter drain to the next lower, successively.

A similar route, naturaly aspirated, no injection seems more promising. Gasification (or misting) frequency is not audio, but near 2MHz The wrongly called 'ultrasonic' 5 micron droplets fogger transducers are cheap and available at many vendors. ----> [http://www.youtube.com/watch?v=VKb7KWTYgdo] -remove brackets-

Hi. Pretending to be or learning to grow, on a tiny portion of 1 acre backyard for personal use. As far successful with garlic, onions, tomatoes, strawberries, lettuce, blueberries, cucumbers, bell pepper, parsley, coriander. Things easy for a beguinner. Unsuccessful with capers To avoid weeding, using black plastic. A very raised bed (1 m) helps the back... as my father said, he would had liked to be farmer, but the soil is way too low. ----> http://i588.photobucket.com/albums/ss323/Innernet/P1010395_zpsaa54b628.jpg ----> http://i588.photobucket.com/albums/ss323/Innernet/P1010396_zpsfe94b2c1.jpg ----> http://i588.photobucket.com/albums/ss323/Innernet/P1010141_zps48ce18d1.jpg

Studies I cannot help with. But have two junipers the exact same age, one in a closed test tube and one in an open small plastic pot. http://www.scienceforums.net/topic/78009-junipers-in-captivity-gardening/?hl=junipers The captive one in the test tube is ~3 cm tall, healthy, green, alive and happy (or bored) Seems to me the lack of air is what holds its growth, but no expert. There is no rubbing against the container, nor hitting the 'roof' A couple of other junipers are ~ 2 years old and not growing in larger closed containers, with some soil and moisture. Also green and healthy all year, kept indoors in good light but no direct sun.

My questionable formatted post was written with Gedit, on Linux Ubuntu + Gnome + Firefox and pasted here. If matters knowing. Was not typed on the reply window directly.

Agree. English is very imprecise, because is being constantly deformed by mostly laziness of the writers/speakers, beyond its already crooked birth. There is no regulator for the language, as shown here : ----> http://en.wikipedia.org/wiki/List_of_language_regulators They want a dictionary publisher to be the ruler. And there is more than one. So if a few want to respect the language, there is no support. The habitual "excuse me !". When I answer "Yes, I excuse you !" You have to see their faces. Mail and male pronounced the same. Then why write them different ? Responding with a dozen 'you know' per minute when asked a question. Useless k in knife, knock, knight... People born in U.S. believe they are not 'native Americans' Not even educated scientists say gasoline, Amperes, advertisement, identification, mathematics, demonstration, temporary, temperature, carburetor, carbohydrate, laboratory, hippopothamus, rhinoceros, application or petroleum any more, from pure laziness. Terrific can be a good thing now. Laziness is saying oh instead of zero. Law could be better written lo, and Phoenix as finix The stupidity of babbling mrs or ma'am instead of just saying mistress or madam -or is it madame?-. Footage ? Snow tires... Rubber ones would not melt. Wood screws... metal ones are better. And what is the business of putting an u in bisnes or bisy In permanent addiction to acronyms England yes, but never got why writing the adjective english muffins with upper case. Whoever decides bootup, software, googling are words have lamb followers and claim to 'coin' those with no relation to coins. The laughable 12:20 AM. There is no such thing; it is 00:20 ! And it never ends... It is beyond fixing. http://montreal.ctvnews.ca/drop-the-english-dictionary-quebec-comedians-parody-language-police-1.1208033 http://ddeubel.edublogs.org/2011/10/28/top-5-funniest-videos-about-teaching-english/ ----> Smile, tomorrow will be worse !

Thanks, gentlemen. It is my third summer playing with plants and successful/happy so far but the oxheart tomato plants could had been much better in the past, now I will do drip irrigation instead of sprinklers to see if fungi (early blight) can be left out of the fight. No more corn again, fully destroyed by deer. And planning to drown slugs in beer to keep the strawberries for me. Yes, can be done as you suggest without sweating the small stuff, but always curious of learning the hidden details for success. Small details always make a difference -sometimes big- and more knowledge won't harm.

It is never ok to steal anything anywhere. Just remember ideas are worth "a penny a bale in 10 bale lots" Instead, put it to work now for the advance of science, as you say.

Hi. Amateur gardener learning, been told/read that higher temperatures (to a limit, and unrelated to sunlight amount) are more convenient for plant growth -at least for garden vegetables- But roots should be kept cooler ? Irrigation in form of artificial rain, as sprinklers/misters can promote undesired fungus, better water only the soil sorrounding* the plant. Irrigation in form of artificial rain, as sprinklers/misters will reduce the plants temperature they prefer for optimal growth, specially when the water source is colder than ambient. * Surrounding somewhat far from stems to promote roots expansion seeking moisture. Do you share the opinion then, that natural/artificial rain is not the best of irrigation systems ? Drip irrigation being more convenient ? [unsure if this should be under another forum; please act accordingly moving if needed]

The most noticeable difference is under their fingernails.

Magnetrons and transmitters can be as efficient as you wish, but propagation losses of radio frequencies render any long distance delivery unuseable.

Thanks all. Endy : Your post does not convince nor impress a bit. Those are percentages of air composition. Air content in soil is greatly lower than atmosphere. In one cubic metre of air there is one million cubic centimetres of air. In one cubic metre of soil, being lucky, there will be a few cubic centimetres of air; comparatively nearly nothing. 20.6% of nearly nothing is still nearly nothing for the roots to gather, when above the soil there is plenty. The amount of oxygen a species need may be genetic, some needing less. If it was critical for the roots, evolution should had developed another approach to gather oxygen. That is the origin of my question.

It is known plants need their roots to absorb oxygen for proper development. -I think- Seems to me the amount of oxygen available deep in packed soils should be minimal or near to nothing, but, there is still some availability. I would like to know if such oxygen is necessary for the root itself or for the general development of the rest of the plant. If the oxygen is to develop roots, something does not click in the evolution, where plants could had developed some above ground tissues for capturing it or exposing some of their roots to air. If the little oxygen available in the soil is to develop general above-the-soil tissue growth, well, same situation; with so much air exposed surfaces, why evolution did not grab it from the air ? If some roots are exposed on purpose by excavation, or by soil erosion/landslides; would that bring a healthier growth ?

Dismantling those may be too damaging. Easier source are computer fans. If you do not know how to dismantle one (remove label and tiny circlip) It is on the circuit board. Shown here----> http://www.pcbheaven.com/wikipages/images/thumbs/howbrushlessmotorswork_1269516340.jpg

Thanks, Greg. Yes, tried several ways, including rubbery undercoating spray instead of the foam : not rigid result. The foam-in-a-can product does not 'spray' out of the can, that is the problem. It just flows slowly out of its dispenser tube and it is totally unmanageable, untouchable until set. Dressed a plastic film on top of item, covered/conformed with the net, and applied the foam : untrowelable. The item to be made is 6' x4', somewhat convoluted.
