They were tested 9 times for a period of 45 minutes. It would be better to do it 9 separate days because then you can see if the results are consistent and what effects other variables might have on the results.

The hull shell that is physically connected to the water outside shouldn't much exceed the boiling point of water if heat was directly applied to it. Think of a non-electric kettle with a heat source directly heating the metal. Maybe you are too young to remember them.

The social neuroscience of cannabis smoking
StringJunky replied to tkadm30's topic in Anatomy, Physiology and Neuroscience
Now you need to support your hypothesis with evidence because you've posted in a conventional science section that requires such support. -
Sweaty cheeks when eating cheese
StringJunky replied to trickrick's topic in Anatomy, Physiology and Neuroscience
A casual search found this: -
No, the intensity diminishes i.e. there are less photons per unit area as the distance increases.
-
That experiment was done in the dark. In your fly example there will be much more noise from other photons coming in from elsewhere.

For those of you lot who actually work in a lab of some sort...

Should have been EOD. -
It would vanish to us because of the limits our eyes but not to more sensitive instruments; photons will travel indefinitely in a vacuum.
-
No, there will still be a 'line' of photons reaching you which can excite a sensor cell. When you see stars in the sky, that is not their apparent size, it is the size of one of your rods on your retina, which has been excited by a photon
-
No, I don't think it makes any difference, in theory, when we assume nothing is in the way to absorb the photons. A bigger light source can chuck out more photons but the effect will be the same on each photon, whether from a large source or smaller source

You can only see as far as your own bubble allows.

To expand what Strange said on the OU. You are at the centre of the sphere and it moves with you, so, if you went 100LYRS out from Earth, your OU would extend 100LYRS futher than us on Earth but you wouldn't see as far behind you as us because your sphere has moved.

Lactobacillus and Bifidobacteria metabolism
StringJunky replied to StringJunky's topic in Biochemistry and Molecular Biology
Thanks. Your comments are good pointers. I know the area I'm interested in but I appreciate I need the fundamentals first. Hopefully, that book will get me started. Forty to fifty quid, after a casual browse, seems about right for a book like that. I'm kind of seeing humans and their commensal organisms as subsets of higher organism... we can't function optimally without them... if I can put it that way. What we call humans is the totality of everything that resides and functions as a unit in the space that is a person. I've found a copy to download. If it's up my street I'll buy the physical book as it looks to be a definitive first year student text going by reviews.... not surprising, coming from you. -
Gluing Rubber to Glass for a strong flexible bond
StringJunky replied to Jmanm's topic in Applied Chemistry
I think so too. I've used some very strong pads but can't remember the name or source. I would think my link to 3M has something. -
Jack, in that context, I think, means a common person that can do several things but has no guild membership of any particular trade.

Lactobacillus and Bifidobacteria metabolism
StringJunky replied to StringJunky's topic in Biochemistry and Molecular Biology
Yeah, I thought other micro-organisms could use them but i'm interested in those two in particular as commensal organisms.Do they secrete the enzyme then absorb the glucose so their is competition for what they produce? Are hydrogen and methane byproducts of their metabolism ? I find myself interested in the gut flora; about the symbiotic relationships between them and their hosts. Also, how they affect the immune system. I thought understanding their metabolism and ecological niches would the place to start. I've just chosen those two organisms arbitrarly because they are populous in the gut and seem to be major players in human-bacteria symbiosis. Do you know any resources or books that would get me started? I have a basic level of carbon chemistry knowledge and could learn more. -
'jack-o-lantern' is derived from a story, it appears. It could, also be a source of jackass because the character was a bad person

Gluing Rubber to Glass for a strong flexible bond
StringJunky replied to Jmanm's topic in Applied Chemistry
I don't know where you are but this seems to meet your spec. Note the exceptions though lower down. If you know it's urethane though it won't work http://www.loctiteproducts.com/p/cntct_vnylpl/overview/Loctite-Vinyl-Fabric-&-Plastic-Flexible-Adhesive.htm Perhaps looking into strong, double-sided adhesive pads/tape may be better. http://solutions.3m.co.uk/wps/portal/3M/en_GB/tapes-adhesives/-/tapes/double-sided-tape/ If the right one is not wide enough, place pieces side-by-side on grip then cut flush with a sharp knife, peel the other side and stick it on the screen. Make sure the adhering surfaces are spotless. -
It is a prefix or suffix with a meaning that can mean 'male', 'large', 'heavy' or 'lift'.

What are good, scientific sources about human vaccines ?
StringJunky replied to koti's topic in Biology
CharonY wouldn't say anything unless he knew he could back it up and would state the degree of confidence, especially in a matter like this.
