Problem: A trend in the late 20th century was for breweries to run their pubs directly, using managers rather than tenants. Most such breweries, such as the regional brewery Shepherd Neame in Kent and Young's and Fuller's in London, control hundreds of pubs in a particular region of the UK, while a few, such as Greene King, are spread nationally. The landlord of a tied pub may be an employee of the breweryin which case he/she would be a manager of a managed house, or a self-employed tenant who has entered into a lease agreement with a brewery, a condition of which is the legal obligation (trade tie) only to purchase that brewery's beer. The beer selection is mainly limited to beers brewed by that particular company. The Beer Orders, passed in 1989, were aimed at getting tied houses to offer at least one alternative beer, known as a guest beer, from another brewery. This law has now been repealed but while in force it dramatically altered the industry. Some pubs still offer a regularly changing selection of guest beers.
What is a notable brewery in Kent that owns hundreds of pubs?
The answer is the following: Shepherd Neame

Input: Compact disc
Heitaro Nakajima, who developed an early digital audio recorder within Japan's national public broadcasting organization NHK in 1970, became general manager of Sony's audio department in 1971. His team developed a digital PCM adaptor audio tape recorder using a Betamax video recorder in 1973. After this, in 1974 the leap to storing digital audio on an optical disc was easily made. Sony first publicly demonstrated an optical digital audio disc in September 1976. A year later, in September 1977, Sony showed the press a 30 cm disc that could play 60 minutes of digital audio (44,100 Hz sampling rate and 16-bit resolution) using MFM modulation. In September 1978, the company demonstrated an optical digital audio disc with a 150-minute playing time, 44,056 Hz sampling rate, 16-bit linear resolution, and cross-interleaved error correction codespecifications similar to those later settled upon for the standard Compact Disc format in 1980. Technical details of Sony's digital audio disc were presented during the 62nd AES Convention, held on 1316 March 1979, in Brussels. Sony's AES technical paper was published on 1 March 1979. A week later, on 8 March, Philips publicly demonstrated a prototype of an optical digital audio disc at a press conference called "Philips Introduce Compact Disc" in Eindhoven, Netherlands.

When did Sony release it's AES technical paper?
Output: 1 March 1979

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.

Invalidation is separate from withdrawal, suspension, or termination (addressed above), which all involve an alteration in the consent of the parties of a previously valid treaty rather than the invalidation of that consent in the first place.
A treaty might be considered what if it's considered unenforceable and void under international law?

invalidated
