Q: Sumerian cities during the Uruk period were probably theocratic and were most likely headed by a priest-king (ensi), assisted by a council of elders, including both men and women. It is quite possible that the later Sumerian pantheon was modeled upon this political structure. There was little evidence of organized warfare or professional soldiers during the Uruk period, and towns were generally unwalled. During this period Uruk became the most urbanized city in the world, surpassing for the first time 50,000 inhabitants.

A: What is an "ensi"?

Q: In cpDNA, there are several A → G deamination gradients. DNA becomes susceptible to deamination events when it is single stranded. When replication forks form, the strand not being copied is single stranded, and thus at risk for A → G deamination. Therefore, gradients in deamination indicate that replication forks were most likely present and the direction that they initially opened (the highest gradient is most likely nearest the start site because it was single stranded for the longest amount of time). This mechanism is still the leading theory today; however, a second theory suggests that most cpDNA is actually linear and replicates through homologous recombination. It further contends that only a minority of the genetic material is kept in circular chromosomes while the rest is in branched, linear, or other complex structures.

A: What kind of gradients does cpDNA have?

Q: In 2008 the Government of Canada made efforts, through the Canada First Defence Strategy, to modernize the Canadian Armed Forces, through the purchase of new equipment, improved training and readiness, as well as the establishment of the Canadian Special Operations Regiment. More funds were also put towards recruitment, which had been dwindling throughout the 1980s and '90s, possibly because the Canadian populace had come to perceive the CAF as peacekeepers rather than as soldiers, as shown in a 2008 survey conducted for the Department of National Defence. The poll found that nearly two thirds of Canadians agreed with the country's participation in the invasion of Afghanistan, and that the military should be stronger, but also that the purpose of the forces should be different, such as more focused on responding to natural disasters. Then CDS, Walter Natynczyk, said later that year that while recruiting has become more successful, the CF was facing a problem with its rate of loss of existing members, which increased between 2006 and 2008 from 6% to 9.2% annually.

A:
What was the effort called to upgrade the Canadian Forces?
