The source of the seaweed used to make laverbread was historically the Gower coastline. There are still small producers of Gower laverbread (Welsh: BARA LAWNR), but most commercial laverbread is now made from seaweed gathered from western Scotland. In addition to Wales, laverbread is eaten across the Bristol Channel in North Devon, especially around the Exmoor coast around Lynmouth and Combe Martin.

Here is the answer: United Kingdom 58.53% (59.62%); United States 11.21% (10.95%); Australia 3.14% (3.18%); France 2.60% (2.79%); Netherlands 2.19% (2.07%); Japan 1.26% (1.35%); Germany 1.17% (1.18%); Ireland 1.07% (1.13%); New Zealand 1.00% (1.03%); Canada 0.97% (1.01%). The numbers in paratheses are the previous percentages. Her popularity will continue to rise in the U.S. and probably in France and the Netherlands. In New Zealand, she has to compete with Yulia MacLean, who brings everyone to tears.
Unlike other singers who are popular because of the songs they sing, the songs that Katherine and Yulia sing become popular because they sing them. Some people who think they are tone deaf and don't like music and religion can't help loving Hallelujah after Katherine sings it.

There are various ways of creating the necessary double degeneracy for encoding a qubit.
In another variant, a d-wave Josephson junction could be tuned to create the doubly degenerate ground states. Other variants have also been by proposed by Guido Burkard's team at the University of Konstanz and others.

Today’s technology does allow the construction rudimentary electromagnetic sensors and associated signal processing capability. The “spin filters” in the disk drive of current day laptop computers are only ones that people are generally aware of. This is seen as the starting point of where technology could go. Graphene provides not only a variety of for constructing such spin filters, but allows the possibility of other types of sensors, such as electrostatic, thermodynamic, etc.
Spin filters are constructed out of more primitive devices that can be fabricated from graphene. These include nanodisks, quantum dots, functionalized subwavelength quantum dots, etc. Using valley filters provides a sensor in the electrostatic domain complementary to the electromagnetic ones. Similarly, the techniques of electron counting spectroscopy permit the construction of probes to explore thermodynamic properties, such as thermal gradients and other statistical properties leading to the construction of motors controllable on a subnanometer scale, etc. In summary, graphene provides the new types of devices needed to construct sensors, processors, and a radical new type of technology.

The total magnetic moment of graphene is zero when there are equal numbers of carbon atoms in its 2-brane and chiral complement. In the general case the total magnetic moment is half the difference between the numbers of atom populating the 2-branes. The magnetization in a zigzag edge has ferromagnetic ordering on each edge, but anti-ferromagnetic coupling between the edges. A single layer of graphene under low magnetic field oscillations has a Berry phase of pi while two layer systems display a Berry phase of 2pi. Similarly, a single layer has almost negligible magnetoresistance, while more than one layer has more conventional properties. Two layer graphene is most notable with respect to its noise cancelling properties.
Internal and external migration of carbon atoms forming pentagons and heptagons can warp the shape of the 2-brane without affecting the threefold coordination of the carbon atoms.
When a single carbon atom is missing from an internal hexagon, the resulting pentagon has “weak” and “gravitational” effects:
1. It exchanges the amplitudes of the two lattices.
2. It exchanges the two Fermi points.
3. It induces a phase coupling proportional to the deficit angle.
4. It induces local (4nm) “gravitational” curvature in spacetime and thus in the sheet. Spin connections provide a generalization of gauge fields used to model spacetime.
The resulting heptagon is paired with a pentagon. The pair acts as a diplole. The pentagon attracts charge and the heptagon repels charge. The heptagon induces negative “gravitational” curvature.

Can you imagine two different time orderings giving rise to the same physical observable event as in the Feynman - Stuckelberg interpretation?
How do you visualize entanglement?
Is a hydrogen atom entangled with anti-particles a more tractible problem?
Does soaking the hydrogen atom in a sea of electrons make it easier to peal back the layers, like soaking a nut in water?

My favorite quotes from the world's greatest living mathematician:
Vous soulignez, a juste titre, la difficulte psychique de la creation solitaire...C’est la la situation qui a ete la mienne plus ou moins pendant toute ma vie, depuis mon enfance, tant sur le plan de la creation mathematique, que dans mon itineraire spirituel... Et sans cela, rien de grand ne s'accomplit, ni dans l’aventure individuelle, ni dans l’aventure collective – que ce soit au plan intellectuel, ou au plan spirituel... Au niveau spirituel, la plus grande ouevre (a mes yeux) qu’un homme ait accomplie, etait la Passion du Christ et sa mort sur la croix... Cette oeuvre etait et ne pouvait etre que solitaire. Et meme c’etait la solitude supreme, car Dieu Lui-meme s’est retire, pour que l’Oeuvre s’accomplisse sans le secours d’une consolation.
Les lois mathematiques peuvent etre d´ecouvertes par l’homme, mais elles ne sont crees ni par l’homme ni meme par Dieu. Que deux plus deux egale quatre n’est pas un d´ecret de Dieu, qu’Il aurait ete libre de changer en deux plus deux egale trois, ou cinq. Je sens les lois mathematiques comme faisant partie de la nature meme de Dieu – une partie infime, certes, la plus superficielle en quelque sorte, et la seule qui soit accesible a la seule raison.

The panel discussion at the 2005: Environmental Epigenomics, Imprinting and Disease Susceptibility Conference available on video touched on this. Note that some of the remarks by the panel are merely intended to be humorous. The videos of all conference presentations as well as links to those for six other conferences are at http://www.geneimprint.com/site/meetings/2005-durham.
Food is now grown in areas in the U.S. like cotton fields, etc., that were formerly treated with arsenic. Water supplies contaminated with arsenic are a problem in many areas of the world.

It is not the lead content of your food that is paramount. It is the amount that absorbed and used in toxic ways by the body. Listen to the advice on cleaning up the environment and proper nutrition from the researchers. Complain to the authorities about the convicted felons running the scams to defraud the public.
The rate at which the human body absorbs and removes lead depends on the state of nutrition. Adequate calcium, iron, phosphorus, vitamin C, D and various trace minerals are needed by the body to minimize the adsorption of lead and to remove it from the body. The body has numerous mechanisms for removing lead. These range from the various forms of excrement and the normal replacement of cells to the not so obvious ones like the breakdown of hemoglobin by the gall bladder and natural chelating processes. The important thing to remember is the body can deal with most environmental factors providing it has an adequate supply of the critical nutrients. The best defense is to help clean up or neutralize the contamination and to make sure each meal is balanced in the proper manner for human nutrition.

2. Make the world wealthy. I am asking everyone to sign up to start earning residual income to secure their financial future. You can sign up for free at http://www.mypowermall.com/Biz/Home/98284.
3. Make the world one community. I am asking everyone to join religious groups and professional societies in order to work together. Most of the professional societies like IEEE and ACM that I belong to, offer online courses that more than offset the cost of membership. Almost no one attends the chapter meetings and dinners. So please join and attend. I invite anyone to join me at Sunset Beach Christian Church in Hawaii for worship and fellowship. Please pray for us to find a pastor to guide us in setting a good example and making a real difference in the world. Give everyone a smile, a friendly gesture with the love and real communication everyone deserves.
