Ceradyne , Incorporated is a wholly owned subsidiary of the British company, Avon Rubber. Ceradyne, Inc. is a manufacturer of advanced ceramic systems and components and involved in many technical industries including nuclear power , oil and gas , solar energy , automotive , and defense.
61-492: Ceradyne was founded in 1967 and in late 2004, the company added new product lines by acquiring ESK Ceramics of Kempten, Germany . In addition to producing ceramic components for industrial processes such as silicon foundries and ceramic fuel pellets for nuclear reactors, Ceradyne researched and produced varieties of ballistic armour for both personnel and vehicles. The ceramic armor was lighter than regular steel plate armor facilitating greater mobility. On September 16, 2007,

Regardless of whether he was actually able to take them in combat, however, Drusus' untimely death would prevent him from ever going through with the official ceremony. Notably, after Drusus' death, Augustus deposited the laurels from his fasces not in the Temple of Jupiter Optimus Maximus as he had done in the past, but in

Lindsay Powell believes that Drusus personally (despite his young age) may have changed his name directly after his father's death to preserve and honor his memory. In her opinion another motivation for the boy may have been the meaning of

After Drusus' death, Antonia never remarried, though she outlived him by nearly five decades. Three emperors were direct descendants of Drusus: his son Claudius , his grandson Caligula , and his great-grandson Nero . Augustus bestowed many honors on his stepsons. In 19 BC, Drusus was granted the ability to hold all public offices five years before

Suetonius reports that he had refused to return to Rome just before his death. Drusus' body was brought back to the city, and his ashes were deposited in the Mausoleum of Augustus . He remained extremely popular with the legionaries , who erected

The Senate raised an arch on the Appian Way in his memory (unrelated to the Arch of Drusus ) which read "DE GERM" and depicted his Elbe trophy as well as him fighting on horseback, a testament to his personal bravery. They also posthumously granted him the hereditary honorific title "Germanicus", which

Drusus was given the honor of an ovation , and for the third time, Augustus closed the doors of the Temple of Janus , signifying that the whole Roman world was then at peace. Drusus was granted the office of proconsul for the following year. In 10 BC, the Chatti joined with the Sicambri and attacked Drusus' camp, but they were driven back. Drusus pursued them, proceeding from

In 15 BC Roman troops led by Nero Claudius Drusus and his brother Tiberius conquered and destroyed the existing Celtic settlement. In the following years the city, whose name was Latinized as Cambodunum , was rebuilt on a classical Roman city plan with baths, forum and temples. Initially in wood,
610-541: Is incompatible with Suetonius account as he cannot accept that Livia and Octavian (once married) would have allowed the adoption of the boy to take place at all, due to Gallius opposition of Octavian. Since Seutonius makes it clear that Tiberius did use Gallius name (although briefly) but dropped it out of respect for his step-father the adoption must have happened before Drusus was born. Jean Mottershead proposed in her commentary of Suetonius 's Divus Claudius that Drusus' praenomen derived from his father's maternal side of

His death slowed the northward expansion of the Roman Empire, and foreshadowed the disastrous Battle of the Teutoburg Forest . He was enormously popular among his men, who erected the Drususstein in his honor; his memory was elevated during the reign of his son Claudius. Drusus' accomplishments in battle were considerable.

This time, he assembled a force consisting of all or part of five legions in addition to auxiliaries and, setting out from Vetera on

As governor of Gaul, Drusus made his headquarters at Lugdunum, where he decided to establish the concilium Galliarum or ‘council of the Gaulish provinces’ sometime between 14 and 12 BC. This council would elect from its members a priest to celebrate games and venerate Rome and Augustus as deities every 1 August at the altar of the three Gauls that Drusus established at Condate in 10 BC. Drusus' son Tiberius—the future emperor Claudius —was born in Lugdunum on

He reached the Werra Valley before deciding to turn back for the season, as winter was coming on, supplies were dwindling, and the omens were unfavorable. While his forces were making their way back through the territory of the Cherusci , the latter tribe laid an ambush for them at Arbalo. The Cherusci failed to capitalize on their initial advantage, whereupon

To show his continued mastery of the ground, Drusus garrisoned a number of positions within Germania during the winter of 11–10 BC, including one somewhere in Hesse and one in Cheruscan territory, probably either the camp at Haltern or that at Bergkamen-Oberaden , both in present-day North Rhine–Westphalia .

The surviving Latin work Consolatio ad Liviam is framed as an Ovidian message of consolation to Livia on this occasion, though it is generally considered a literary exercise "composed between the death of Livia [AD 29] and that of Tiberius [AD 37]".

Simpson stated that in his opinion Livia chose the names Decimus and Drusus for her younger son to minimize association with her ex-husband after she married Octavian due to

While the furthest extent of territorial gains would be realized the year after his death, under Tiberius, Drusus' death marked a slowing of Roman expansion. Drusus' successors would prove unfit for the task of conquering Germania, with disastrous results.

Historian Michael McNally considers Drusus to have been

Starting in 14 BC, Drusus built a string of military bases along the Rhine—fifty according to Florus —and established an alliance with the Batavi in preparation for military action in Germania Libera. He is likely to have had seven legions under his command. In spring of 12 BC, he embarked an expeditionary force, perhaps consisting of the Legiones I Germanica and V Alaudae , by ship from

In summer of 10 BC, Drusus left the field in order to return to Lugdunum , where he inaugurated the sanctuary of the Three Gaulish provinces at Condate on 1 August.

His consulship conferred the chance for Drusus to attain Rome's highest and rarest military honor, the spolia opima , or spoils of an enemy chieftain slain personally by an opposing Roman general who was fighting (as consuls did) under his own auspices.

Drusus was the youngest son of Livia Drusilla from her marriage to Tiberius Claudius Nero , who was legally declared his father before the couple divorced. Drusus was born between mid-March and mid-April 38 BC, three months after Livia married Augustus on 17 January. Gerhard Radke has proposed

Simpson personally argued against the time of adoption of his brother as a plausible time for his name change since Simpson believed
