The later development of the legends of the Holy Grail and Joseph of Arimathea by Robert de Boron interconnected these legends with Glastonbury and with Avalon an identification which also seems to be made in Perlesvaus.

Boron is also involved in the carbohydrate metabolism in plants, protein synthesis, seed and cell wall formation, germination of pollen grains and growth of pollen tubes and sugar translocation.

Boron is an excellent neutron absorber ( and also undergoes some neutron scattering ) which decays into carbon or helium and produces virtually no gamma radiation, with boron carbide a commonly used shield where concrete would be cost prohibitive.

Boron is believed to be involved in carbohydrate transport in plants ; it also assists in metabolic regulation.

Robert de Boron ( also spelled in the manuscripts " Bouron ", " Beron ") was a French poet of the late 12th and early 13th centuries who is most notable as the author of the poems Joseph d ' Arimathe and Merlin.

Robert de Boron is also credited with introducing Merlin as the son of the Antichrist.

* in the late 12th or early 13th century, Robert de Boron associates the wizard Merlin with Brocéliande in his poem Merlin, also known as the Estoire de Merlin, or the Vulgate or Prose Merlin.

Boron can be combined with hydrogen, but Borane ( boron hydride ) forms dimers and clusters rather than a monomer.

Boron nitride exists as several forms ( polymorphs ).

Boron carbide, B < sub > 4 </ sub > C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms.

Perceval, although unfinished, was particularly popular: four separate continuations of the poem appeared over the next half century, with the notion of the Grail and its quest being developed by other writers such as Robert de Boron, a fact that helped accelerate the decline of Arthur in continental romance.

The company used the same logo, but with " Boron " as the brand name in other states.

Chrétien de Troyes wrote the first story of Perceval, le Conte du Graal ; Wolfram von Eschenbach's Parzival, Sir Thomas Malory's Le Morte d ' Arthur, and the now lost Perceval of Robert de Boron are other famous accounts of his adventures.

Boron is often used because its bond lengths are significantly shorter than that of other metals such as lithium, aluminium, or magnesium.

The mule is honored at Benson, N.C. ( Sept. 22, 23 ) and at Boron, Calif. ( Sept. 24 thru Oct. 1 ), while the legend of the Maid of the Mist is celebrated at Niagara Falls through the 24th.

Boron () is a chemical element with chemical symbol B and atomic number 5.

Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.

Boron polymers and ceramics play specialized roles as high-strength lightweight structural and refractory materials.

Boron compounds are used in silica-based glasses and ceramics to give them resistance to thermal shock.

Boron is essential to life.

Boron compounds were known thousands of years ago.

Boron compounds were relatively rarely used chemicals until the late 1800s when Francis Marion Smith's Pacific Coast Borax Company first popularized these compounds and made them in volume and hence cheap.

Boron was not recognized as an element until it was isolated by Sir Humphry Davy and by Joseph Louis Gay-Lussac and Louis Jacques Thénard.

Boron is similar to carbon in its capability to form stable covalently bonded molecular networks.

Other authors had their own ideas: Robert de Boron portrayed it as the vessel of the Last Supper ; and Peredur had no Grail per se, presenting the hero instead with a platter containing his kinsman's bloody, severed head.

Though Chrétien ’ s account is the earliest and most influential of all Grail texts, it was in the work of Robert de Boron that the Grail truly became the " Holy Grail " and assumed the form most familiar to modern readers.

* The Didot Perceval, named after the manuscript ’ s former owner, and purportedly a prosification of Robert de Boron ’ s sequel to Joseph d ’ Arimathie.

The occurrence locale was the US Borax Mine at Boron in the western Mojave Desert.

Boron is the most common etch-stop dopant.

Merlin reciting his poem s, as illustrated in the French book from the 13th century " Merlin ", by Robert de Boron.

Several decades later, the poet Robert de Boron retold this material in his poem Merlin.

Robert de Boron lays great emphasis on Merlin's power to shapeshift, on his joking personality, and on his connection to the Holy Grail.

Much of this work is summarized in a book by Gareth Eaton and William Lipscomb, NMR Studies of Boron Hydrides and Related Compounds, one of Lipscomb's two books.

* Boron can form intermetallic compounds and alloys with transition metals, of the composition M < sub > n </ sub > B, if n > 2.

Boron ( B ) deficiency is an uncommon disorder affecting plants growing in deficient soils and is often associated with areas of high rainfall and leached soils.

Excavations at the prehistoric site called Terra Amata, at the foot of Mount Boron in Nice, showed that in about 400, 000 B. C.

In the United States, one builder of modern, well-regarded double rifles in a variety of calibers is B. Searcy & Company of Boron, California.

* Boron trioxide ( B < sub > 2 </ sub > O < sub > 3 </ sub >)-the most common form

* Boron monoxide ( B < sub > 2 </ sub > O )

* Boron suboxide ( B < sub > 6 </ sub > O )

Boron ( B ) naturally occurs in two isotopes, < sup > 10 </ sup > B and < sup > 11 </ sup > B, the latter of which makes up about 80 % of natural boron.
