SUMMARY Fifteen anaesthetists attempted to intubate the trachea of a manikin lying supine on the ground using the Airway Scope, Airtraq or Macintosh laryngoscope in three simulated conditions: (1) in room light; (2) in the dark and (3) in daylight. The main outcome measure was the time to ventilate the lungs after successful intubation; the secondary outcome was the success rate of ventilation ...

PURPOSE To evaluate the stability of human binocular alignment under conditions of altered fixation and luminance. METHODS Horizontal binocular alignment in 8 healthy orthotropic subjects was measured using infrared video-oculography (VOG) under conditions of binocular fixation and luminance change. Each testing condition was preceded by a binocular fixation period in room light (475 lux) to ...

Unilateral blue light administered to corn coleoptile segments produces no alteration of transmembrane potential on the light side, and only a small and slow hyperpolarization on the dark side. Red light causes a 5-15 millivolt depolarization in cells on the light side causes and somewhat smaller effects on the dark side. Blue given after red causes a rapid hyperpolarization on both sides of th...

Working women is not a recent phenomenon but in India they still face bias and prejudice against them. This stereotyping can also be traced into the works of literature. paper aims to analyze depiction some working women’s characters early Indian English novels by R.K Narayan. It will try throw light on patriarchal ideology narration projection select novels. How are often put under certain lab...

The active place avoidance task is a dry-arena task used to assess spatial navigation and memory in rodents. In this task, a subject is put on a rotating circular arena and avoids an invisible sector that is stable in relation to the room. Rotation of the arena means that the subject's avoidance must be active, otherwise the subject will be moved in the to-be-avoided sector by the rotation of t...

Si and GaAs metal-semiconductor-metal photodetectors with finger spacing as small as 0.25 mm are studied for 1.3 mm wavelength operation. It was found that the detectors have an external quantum efficiency as high as 0.5% for 1.3 mm light and a low dark current at room temperature. Increasing the Schottky barrier height reduces the responsivity of the detectors, but reduces the dark current mor...

Context. The sterile neutrino is an excellent dark matter candidate, which can be searched for in a wide range of astrophysical sites. It has previously been shown that the optimal search strategy is to consider dwarf galaxies belonging to the Milky Way. Aims. We search for line emission from decaying dark matter. Methods. We analyse publicly available Chandra X-ray observations of the dwarf ga...

A 512 512 CMOS active pixel sensor (APS) was designed and fabricated in a standard 0.5m technology. The radiation tolerance of the sensor has been evaluated with Co-60 and proton irradiation with proton energies ranging from 11.7 to 59 MeV. The most pronounced radiation effect is the increase of the dark current. However, the total ionizing dose-induced dark current increase is orders of magnit...

In photon counting imaging applications a focal plane array consisting of a detector and readout integrated circuit (ROIC) array must both be low noise. At room temperature, InGaAs PIN detector arrays are most suitable because the required signal bandwidth is fairly modest and the first stage input amplifiers on the ROIC can be very low noise. However, in many applications relatively long integ...
