Does polarimetry count as simple? I would expect that even a rudimentary polarimeter should be able to identify if significant amounts of sucrose had been added to a fructose/glucose mixÖYou couldn't use the stuff we normally call "sugar" to make fake honey; it's sucrose and honey is largely glucose and fructose.Depends how itís done. When there is a poor nectar flow - we are about to enter one - beekeepers feed sucrose solution to tide the bees over. The bees will invert the sucrose, but you end up with a diluted flavour so you canít (or rather shouldnít) extract it for sale.
We also use an invert syrup with same glucose/fructose mix as honey so the bees donít waste energy converting it, but same problem of saleability. Unscrupulous people could add the invert directly and I think this has been detected in imported honey.But you could use golden syrup- which is a partially inverted sugar (and thus is much more similar to honey).Honey police will get you
Golden syrup contains high amount of 5-hydroxy methyl furfural (HMF). Honey is tested for HMF as it is a sign that the honey has been overheated in processing and adding golden syrup would push it above the legal limit.
Most amateur beekeepers donít heat their honey in order to keep it as natural as possible.Testing for fakes is interesting enough as a piece of analytical chemistry, but more than a little off topic.That would be a very interesting topic. Particularly if you know a simple test to identify sucrose in honey.
Where is Administration thenakedscientists.com ??Paradoxically, it depends on where you are.
Light trapped by this monopole's singularity gravitational force also is without a wave dynamic, because of the monolithic nature of the monopoles gravity (no waves). So, with no Light waves...This post seems to be suggesting that there can be no light waves within a black hole (ie no light and no photons)?
@CliffordK I have to echo @Bill S comment.They don't. The graph shows distance vs. time. The shape shown for the the curves is an artifact of this.
That chart is fascinating. I knew some stars are getting closer, but didnít realise they had comet like tracks. The dynamics of this system would be interesting to know.
Excellent, context is always useful.
Although lead oxide is red Iím not sure that the tetraethyllead used in fuel produces a particulate which would reflect red, perhaps @chiralSPO could help here. I suspect that the haze is from other pollutants and lead is an indirect cause. As you know particulates are removed from car exhaust by the catalytic converter, unfortunately lead deposits stop the catalyst working so they canít be used in cars using leaded fuel, hence greater pollution.
From wine to recreational inhalants. Slippery slope.
That's because it is also called Ethanolic Acid.Close.
