QUES: Bitumen was used in early photographic technology. In 1826 or 1827, it was used by French scientist Joseph Nicephore Niepce to make the oldest surviving photograph from nature. The bitumen was thinly coated onto a pewter plate which was then exposed in a camera. Exposure to light hardened the bitumen and made it insoluble, so that when it was subsequently rinsed with a solvent only the sufficiently light-struck areas remained. Many hours of exposure in the camera were required, making bitumen impractical for ordinary photography, but from the 1850s to the 1920s it was in common use as a photoresist in the production of printing plates for various photomechanical printing processes.[not in citation given]

QUES: Comcast was given an "F" for its corporate governance practices in 2010, by Corporate Library, an independent shareholder-research organization. According to Corporate Library, Comcast's board of directors ability to oversee and control management was severely compromised (at least in 2010) by the fact that several of the directors either worked for the company or had business ties to it (making them susceptible to management pressure), and a third of the directors were over 70 years of age. According to the Wall Street Journal nearly two-thirds of the flights of Comcast's $40 million corporate jet purchased for business travel related to the NBCU acquisition, were to CEO Brian Roberts' private homes or to resorts.

What organization gave Comcast an "F" rating in 2010?

QUES: Breakthrough pain is transitory acute pain that comes on suddenly and is not alleviated by the patient's normal pain management. It is common in cancer patients who often have background pain that is generally well-controlled by medications, but who also sometimes experience bouts of severe pain that from time to time "breaks through" the medication. The characteristics of breakthrough cancer pain vary from person to person and according to the cause. Management of breakthrough pain can entail intensive use of opioids, including fentanyl.

What activity in relation to breakthrough pain requires heavy use of opiods?
