The combination of high gain, low noise, high frequency response or, equivalently, ultra-fast response, and large area of collection has maintained photomultipliers an essential place in low light level spectroscopy, confocal microscopy, Raman spectroscopy, fluorescence spectroscopy, nuclear and particle physics, astronomy, medical diagnostics ...
In 2010, the pattern of AIPMT was changed. The examination was replaced by a two-tier or two-stage test – The AIPMT Prelims and the AIPMT Mains, in which the AIPMT Prelims was used to be objective exam and AIPMT Mains was used to be subjective exam. The candidates who could qualify the AIPMT Prelims were eligible to give the AIPMT Mains test.

Many extensions of the Standard Model of particle physics, including string theory, propose a sterile neutrino; in string theory this is made from a closed string. These could leak into extra dimensions before returning, making them appear to travel faster than the speed of light. An experiment to test this may be possible in the near future. [30]
The PG programme in Human Resources Management and Labour Relations offered at TISS campuses is at par with the management programmes offered by top MBA colleges in India. The entrance exam is held in CBT mode and the exam paper comprises questions from English Proficiency, Mathematical Skills & Logical Reasoning, and General Awareness.*
The journal is considered one of the most prestigious in the field of physics. Over a quarter of Physics Nobel Prize-winning papers between 1995 and 2017 were published in it. [1] PRL is published both online and as a print journal. Its focus is on short articles ("letters") intended for quick publication. The Lead Editor is Hugues Chaté.
Meanwhile, a laser beam which is perpendicular to the ultrasonic beam will also illuminate the scattering medium. Then, on the other side of the light source, the PMT, modulated by frequency signal sent through the first function generator will detect transmitted light signal within the tank and transfer the optical signal to electrical signal.
Hysteresis vs single-valued: Devices which have hysteresis; that is, in which the current–voltage relation depends not only on the present applied input but also on the past history of inputs, have I–V curves consisting of families of closed loops. Each branch of the loop is marked with a direction represented by an arrow.
