Problem: Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in MayAugust 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World).
Because of his conflicts with the emperors, how was he known?

Context and question: A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulphate, sulfoxide or disulfide poisoning), grapes and raisins, macadamia nuts, xylitol, as well as various plants and other potentially ingested materials. The nicotine in tobacco can also be dangerous. Dogs can get it by scavenging in garbage or ashtrays; eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are highly susceptible to theobromine poisoning, typically from ingestion of chocolate. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that even small amounts of chocolate can be fatal, especially dark chocolate.
What is the chemical in chocolate that is poisonous to dogs?
Answer: theobromine

Question: ASCII itself was first used commercially during 1963 as a seven-bit teleprinter code for American Telephone & Telegraph's TWX (TeletypeWriter eXchange) network. TWX originally used the earlier five-bit ITA2, which was also used by the competing Telex teleprinter system. Bob Bemer introduced features such as the escape sequence. His British colleague Hugh McGregor Ross helped to popularize this work according to Bemer, "so much so that the code that was to become ASCII was first called the Bemer-Ross Code in Europe". Because of his extensive work on ASCII, Bemer has been called "the father of ASCII."
Is there an answer to this question: What did TWX use because to counter slow loading times of ASCII?

It was at Port Said that Nasser saw a confrontation with the invading forces as being the strategic and psychological focal point of Egypt's defense. A third infantry battalion and hundreds of national guardsmen were sent to the city as reinforcements, while two regular companies were dispatched to organize popular resistance. Nasser and Boghdadi traveled to the canal zone to boost the morale of the armed volunteers. According to Boghdadi's memoirs, Nasser described the Egyptian Army as "shattered" as he saw the wreckage of Egyptian military equipment en route. When British and French forces landed in Port Said on 56 November, its local militia put up a stiff resistance, resulting in street-to-street fighting. The Egyptian Army commander in the city was preparing to request terms for a ceasefire, but Nasser ordered him to desist. The British-French forces managed to largely secure the city by 7 November. Between 750 and 1,000 Egyptians were killed in the battle for Port Said.
In what state was the Egyptian army after fighting the French and UK?
A:
shattered
