Fifteen neuro-otological patients have been investigated for post-traumatic vertigo, hearing loss and tinnitus. Clinical examination and laboratory tests included audiometry and equilibriometry in all patients. Statistically significant findings are reported for tinnitus, vertigo, hearing loss. Correlations for vertigo with the type of head trauma, nystagmus frequency Slow Phase Velocity (SPV) ...

We report the observation of collective-emission-induced, velocity-dependent light forces. One-third of a falling sample containing 3 x 10(6) cesium atoms illuminated by a horizontal standing wave is stopped by cooperatively emitting light into a vertically oriented, confocal resonator. We observe decelerations up to 1500 m/s(2) and cooling to temperatures as low as 7 microK, well below the fre...

The purpose of this work is investigation changes in hydrodynamic parameters (absolute pressure, mass flow rates solution and secondary steam, steam velocity, irrigation density, pressure loss) along the length heat exchange tube a vertical falling film evaporator. obtained data distribution were used design evaporators.

Super water-repellent surfaces occur naturally on plants and aquatic insects and are created in the laboratory by combining micro or nano-scale surface topographic features with hydrophobic surface chemistry. When such types of water-repellent surfaces are submerged they can retain a film of air (a plastron). In this work, we report measurements of the terminal velocity of solid acrylic spheres...

We present a study the dynamic properties of EUV spicules. The selected data were obtained as time series in polar coronal holes by SUMER/SOHO. The short exposure time and the almost fixed position allow the analysis of the spicule properties such as: occurrence, lifetime, Doppler velocity, etc. Our data reveal that spicules occur repeatedly at the same location with a birth rate of around 0.1/...

An experimental study was done to determine the diameter and velocity of blood drops falling on a surface by measuring the size of bloodstains they produced and counting the number of radial spines projecting from them. Bloodstains were formed by releasing drops of pig blood with a range of diameters (3.0-4.3 mm) and impact velocities (2.4-4.9 m/s), onto four different flat surfaces (glass, ste...

The compatibility axiom in Ehlers, Pirani and Schild’s (EPS) constructive axiomatics of the space–time geometry that uses light rays and freely falling particles with high velocity, is replaced by several constructions with low velocity particles only. For that purpose we describe in a space–time with a conformal structure and an arbitrary path structure the radial acceleration, a Coriolis acce...

We compared psychophysical thresholds for biological and non-biological motion detection in adults with autism spectrum conditions (ASCs) and controls. Participants watched animations of a biological stimulus (a moving hand) or a non-biological stimulus (a falling tennis ball). The velocity profile of the movement was varied between 100% natural motion (minimum-jerk (MJ) for the hand; gravitati...

For a free falling particle moving in a media which has quadratic velocity force effect on the particle, two equivalent constants of motion, with units of energy, two Lagrangians, and two Hamiltonians are deduced. These quantities describe the dynamics of the same classical system. However, their quantization and the associated statistical mechanics (for an ensemble of particles) describe two c...
