William Champion's brother, John, patented a process in 1758 for calcining zinc sulfide into an oxide usable in the retort process. Prior to this, only calamine could be used to produce zinc. In 1798, Johann Christian Ruberg improved on the smelting process by building the first horizontal retort smelter. Jean-Jacques Daniel Dony built a different kind of horizontal zinc smelter in Belgium, which processed even more zinc. Italian doctor Luigi Galvani discovered in 1780 that connecting the spinal cord of a freshly dissected frog to an iron rail attached by a brass hook caused the frog's leg to twitch. He incorrectly thought he had discovered an ability of nerves and muscles to create electricity and called the effect "animal electricity". The galvanic cell and the process of galvanization were both named for Luigi Galvani and these discoveries paved the way for electrical batteries, galvanization and cathodic protection.
Who first patented the process that creates an oxide usable in the retort process?
****
The answer: William Champion's brother, John,

Restrictions on media censorship were significantly eased in August 2012 following demonstrations by hundreds of protesters who wore shirts demanding that the government "Stop Killing the Press." The most significant change has come in the form that media organisations will no longer have to submit their content to a censorship board before publication. However, as explained by one editorial in the exiled press The Irrawaddy, this new "freedom" has caused some Burmese journalists to simply see the new law as an attempt to create an environment of self-censorship as journalists "are required to follow 16 guidelines towards protecting the three national causes — non-disintegration of the Union, non-disintegration of national solidarity, perpetuation of sovereignty — and "journalistic ethics" to ensure their stories are accurate and do not jeopardise national security." In July 2014 five journalists were sentenced to 10 years in jail after publishing a report saying the country was planning to build a new chemical weapons plant. Journalists described the jailings as a blow to the recently-won news media freedoms that had followed five decades of censorship and persecution.
What did demonstrators wear during the media rally?
****
The answer: wore shirts demanding that the government "Stop Killing the Press.

Francis Hutcheson, a moral philosopher, described the utilitarian and consequentialist principle that virtue is that which provides, in his words, "the greatest happiness for the greatest numbers". Much of what is incorporated in the scientific method (the nature of knowledge, evidence, experience, and causation) and some modern attitudes towards the relationship between science and religion were developed by his protégés David Hume and Adam Smith. Hume became a major figure in the skeptical philosophical and empiricist traditions of philosophy.
In what areas of philosophy did Hume become a major figure?
****
The answer: skeptical philosophical and empiricist traditions


The problem: Answer a question about this article:
Differences in pain perception and tolerance thresholds are associated with, among other factors, ethnicity, genetics, and sex. People of Mediterranean origin report as painful some radiant heat intensities that northern Europeans describe as nonpainful. And Italian women tolerate less intense electric shock than Jewish or Native American women. Some individuals in all cultures have significantly higher than normal pain perception and tolerance thresholds. For instance, patients who experience painless heart attacks have higher pain thresholds for electric shock, muscle cramp and heat.
Along with with ethnicity and genetics, what is the other factor associated with differences in pain perception?
****
The answer:
sex
