Abstract The optical module of the KM3NeT neutrino telescope is an innovative multi-faceted large area photodetection module. It contains 31 three-inch photomultiplier tubes in a single 0.44 m diameter pressure-resistant glass sphere. sensory device also comprising calibration instruments and electronics for power, readout data acquisition. capped with breakout-box connection to electro-optical...

Photons participate in most atomic and molecular interactions and changes in life regulation processes. In this respect, the development of photomultiplier tubes (PMT’s) in the early fifties of the last century was a key event in order to detect photons in biological tissue as reported by Colli et al. [1]. This practical discovery of light emission in cells by a highly sophisticated physical me...

PMT was assessed by manual palpation modified to include the use of a fingertip palpometer.IO·11 Five pericranial muscles (temporalis, masseter, suboccipital. posterior cervical. middle trapezius) were palpated bilaterally with a fingertip pressure of 500 g/cm2• The participant was asked to report tenderness for each palpation site on a scale of 0 (no pain) to 10 (worst pain imaginable). The su...

The purpose of the research presented in this paper is to help characterize and improve the photomultiplier tubes which go inside the Xenon dark matter detector. This paper discusses Dark Matter, the Xenon experiment, and the main project. The main project presented in this paper is the optimization of a parameter of photomultiplier tubes called linearity. Linearity means that the input and out...

Titanium based-perovskites have got surprising attraction due to their environmentfriendly photocatalysts behavior. The Rietveld refinement of X-ray diffraction (XRD) pattern authenticates the orthorhombic Pnma structure Pr2MgTiO6 (PMT). Pr3+-Ti4+ intervalence charge transfer process plays an important role inside PMT. dc conductivity shows a change in hopping mechanism from nearest-neighbor va...

We used a survey design to compare three social cognitive models in their ability to explain intentions of precautionary online behaviour. The models were protection motivation theory (PMT), the reasoned action approach (RAA) and an integrated model comprising variables of these models. Data from 1,200 Dutch users of online banking were analysed with partial-leastsquares path-modelling. The two...

Imaging air Cherenkov telescopes are usually triggered on a coincidence of two or sometimes more pixels, with discriminator thresholds in excess of 20 photoelectrons applied for each pixel. These thresholds required to suppress night-sky background are significantly higher than expected on the basis of a Poisson distribution in the number of night-sky photoelectrons generated during the charact...

Premotor time (PMT) and maximum tension (Fmax) produced by isometric contraction of the left and the right quadriceps femoris for rapid knee extension were examined in 10 normal male subjects at two positions of the left upper extremity, neutral and facilitating position for the triceps brachii. Compared to the neutral position, PMT of the both sides decreased and Fmax increased at the facilita...
