Problem: Infection:

Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen. The antigen, usually a protein or carbohydrate made by an infectious agent, is bound by the antibody. This binding then sets off a chain of events that can be visibly obvious in various ways, dependent upon the test. For example, "Strep throat" is often diagnosed within minutes, and is based on the appearance of antigens made by the causative agent, S. pyogenes, that is retrieved from a patients throat with a cotton swab. Serological tests, if available, are usually the preferred route of identification, however the tests are costly to develop and the reagents used in the test often require refrigeration. Some serological methods are extremely costly, although when commonly used, such as with the "strep test", they can be inexpensive.

A: Serological


Problem: Comcast:

Media outlets began reporting in late September 2009 that Comcast was in talks to buy NBCUniversal. Comcast denied the rumors at first, while NBC would not comment on them. However, CNBC itself reported on October 1 that General Electric was considering spinning NBCUniversal off into a separate company that would merge the NBC television network and its cable properties such as USA Network, Syfy and MSNBC with Comcast's content assets. GE would maintain 49% control of the new company, while Comcast owned 51%. Vivendi, which owns 20%, would have to sell its stake to GE. It was reported that under the current deal with GE that it would happen in November or December. It was also reported that Time Warner would be interested in placing a bid, until CEO Jeffrey L. Bewkes directly denied interest, leaving Comcast the sole bidder. On November 1, 2009, The New York Times reported Comcast had moved closer to a deal to purchase NBCUniversal and that a formal announcement could be made sometime the following week.

Problem: Queen (band):

On 15 August 2006, Brian May confirmed through his website and fan club that Queen + Paul Rodgers would begin producing their first studio album beginning in October, to be recorded at a "secret location". Queen + Paul Rodgers performed at the Nelson Mandela 90th Birthday Tribute held in Hyde Park, London on 27 June 2008, to commemorate Mandela's ninetieth birthday, and again promote awareness of the HIV/AIDS pandemic. The first Queen + Paul Rodgers album, titled The Cosmos Rocks, was released in Europe on 12 September 2008 and in the United States on 28 October 2008. Following the release of the album, the band again went on a tour through Europe, opening on Kharkiv's Freedom Square in front of 350,000 Ukrainian fans. The Kharkiv concert was later released on DVD. The tour then moved to Russia, and the band performed two sold-out shows at the Moscow Arena. Having completed the first leg of its extensive European tour, which saw the band play 15 sold-out dates across nine countries, the UK leg of the tour sold out within 90 minutes of going on sale and included three London dates, the first of which was The O2 on 13 October. The last leg of the tour took place in South America, and included a sold-out concert at the Estadio José Amalfitani, Buenos Aires.

Problem: Incandescent light bulb:

In manufacturing the glass bulb, a type of "ribbon machine" is used. A continuous ribbon of glass is passed along a conveyor belt, heated in a furnace, and then blown by precisely aligned air nozzles through holes in the conveyor belt into molds. Thus the glass bulbs are created. After the bulbs are blown, and cooled, they are cut off the ribbon machine; a typical machine of this sort produces 50,000 bulbs per hour. The filament and its supports are assembled on a glass stem, which is fused to the bulb. The air is pumped out of the bulb, and the evacuation tube in the stem press is sealed by a flame. The bulb is then inserted into the lamp base, and the whole assembly tested.

How is the evacuation tube sealed?

A:
by a flame
