NOTE: Add Map 36: Division of Charlegmagne's Empire at Verdun in 843

Map taken from Reference 97.

As the old Frankish kingdom disintegrated in the early century, the separate duchies previously present reappeared as independent political units. These were the stem

From "Stamm", meaning "tribe"
duchies of Frisia (Lowlands), Saxony, Franconia (along the Maine), Swabia, Thuringia (between the Weser and Elbe) and Bavaria. These were based originally on ethnic unity and this particularism made unification of Germany forever difficult. (Ref. 184 )

In 857 there a serious outbreak of ergotism in which thousands of Germans died, poisoned by their daily rye bread which contained a fungus producing some 20 poisons (including LSD). The disease produced abdominal pain, delirium, gangrene and sometimes death, or alternately it caused an acute inflammation of the skin, driving people to insanity and giving it its common name of "Holy fire". (Ref. 211 ) The only physicians present were part of the monastic environment and much of their labor was devoted to prayer, laying on of hands, exorcising, use of amulets, holy oil, relics of saints and other elements of supernaturalism rather than to rational procedures. (Ref. 125 )

By treaty in 870 Germany was extended from the Rhine to the Elbe. The limits between the Germans and the Slavs generally followed the Elbe between the North Sea and the mountains of Bohemia. Although this line of demarcation did not last for long, it has through the centuries assumed some political, economic and social importance. As noted previously, to the west of the Elbe is old Germany, to the east is new Germany. The latter became the area of the Junkers, with large estates dominating a servile peasantry, with a large Slavic element in the population. A skeleton of imperial power continued even after Ludwig's death. The last of the direct Caroling ian line, Karl (Charles) the Fat, abdicated in 887. Three weak kings filled the next thirty year gap, until the rule was taken over in the next century by the Saxon kings.

Austria

Charlemagne's "Ostmark", bounded by the rivers Enns, Raab and Drau, with a fortress at Vienna, lasted until about 880, when the Frankish forces were defeated by the Magyars who had occupied Hungary and then moved into Austria. (Ref. 175 )

Hungary

In the early century Hungary was lightly held by the Bulgar Khanate, but near the end of the century when the Magyars were finally squeezed entirely out of Russia by the Patzinaks (Pechnegi), they swept through the upper Balkans and took over and settled Hungary. The "native" Szekels were few and scattered and offered little resistance. The Magyars were basically a Finnish people who had an infusion of Turkish blood which had been added while they were living on the Don River and were joined by three hordes of the Khazars from the Volga mouth. The Magyars were free horsemen, living in clans and tribes and using slaves taken from among the Slavs. They spoke the Ugric language of the Finno-Ugric group of Uralic languages. Formerly it was erroneously thought that these people were basically Mongolian or Hunnish, but this is not accurate and they came originally from the Ural Mountains area, not farther east. In Asia, they were called Ugri, from their Ugric language and from this has come our word "ogre". (Ref. 137 )

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
