In December 2005, Imperial announced a science park programme at the Wye campus, with extensive housing; however, this was abandoned in September 2006 following complaints that the proposal infringed on Areas of Outstanding Natural Beauty, and that the true scale of the scheme, which could have raised 110m for the College, was known to Kent and Ashford Councils and their consultants but concealed from the public. One commentator observed that Imperial's scheme reflected "the state of democracy in Kent, the transformation of a renowned scientific college into a grasping, highly aggressive, neo-corporate institution, and the defence of the status of an Area of Outstanding Natural Beauty throughout England, not just Wye against rampant greed backed by the connivance of two important local authorities. Wye College campus was finally closed in September 2009.
How much money could the science park programme have raised for the college?
110m

New Haven has been depicted in a number of movies. Scenes in the film All About Eve (1950) are set at the Taft Hotel (now Taft Apartments) on the corner of College and Chapel streets, and the history of New Haven theaters as Broadway "tryouts" is depicted in the Fred Astaire film The Band Wagon (1953). The city was fictionally portrayed in the Steven Spielberg movie Amistad (1997) concerning the events around the mutiny trial of that ship's rebelling captives. New Haven was also fictionalized in the movie The Skulls (2000), which focused on conspiracy theories surrounding the real-life Skull and Bones secret society which is located in New Haven.
The fim Amistad uses references to New Haven in the movie, who was the director of Amistad?
Steven Spielberg

Ion gauges are used in ultrahigh vacuum. They come in two types: hot cathode and cold cathode. In the hot cathode version an electrically heated filament produces an electron beam. The electrons travel through the gauge and ionize gas molecules around them. The resulting ions are collected at a negative electrode. The current depends on the number of ions, which depends on the pressure in the gauge. Hot cathode gauges are accurate from 103 torr to 1010 torr. The principle behind cold cathode version is the same, except that electrons are produced in a discharge created by a high voltage electrical discharge. Cold cathode gauges are accurate from 102 torr to 109 torr. Ionization gauge calibration is very sensitive to construction geometry, chemical composition of gases being measured, corrosion and surface deposits. Their calibration can be invalidated by activation at atmospheric pressure or low vacuum. The composition of gases at high vacuums will usually be unpredictable, so a mass spectrometer must be used in conjunction with the ionization gauge for accurate measurement.
What are the two types of Ion gauges?
hot cathode and cold cathode.
