Sudden Stop

The lower part of a skyscraper possesses enormous weight giving the gravity of the total building, whereas the upper part is smaller in mass. Upon a gust of wind or other factors, the lower part accelerates and decelerates more slowly than the upper part, and then the upper part moves backwards first and then forwards. It resembles a traveling bus, the standing passengers move backwards and forwards upon vehicle starting from standing-still or a sudden stop.

Caloric Deficit

Post-headshake nystagmus (PHN) has recently been described as a clinically useful physical sign implying uncompensated asymmetric input from the vestibular end organs. A rapid 20-second headshake and sudden stop produces a jerk nystagmus of 5- to 20-second duration in certain individuals with symptoms suggestive of a peripheral vestibulopathy. This retrospective review of 214 patient evaluations was undertaken to study the associations between post-headshake nystagmus, caloric deficits after bi-thermal binaural irrigation, and the presence of vertigo. Both clinical observation of the nystagmus with eyes open (PHN-OBS) and routine EOG recording with eyes closed (PHN-EOG) were used. In patients with unilateral caloric deficits, 42% (18 of 43) had PHN-EOG, compared with 18% (3 of 17) in patients with bilateral dysfunction and 15% (23 of 154) in patients with normal calorics (p < 0.001H). In similar fashion, 26% (32 of 124) of patients with vertigo (recent or past) had PHN-EOG compared to 13% (12 of 90) of patients without vertigo (p < 0.03). Finally, of 110 cases with both PHN-EOG and PHN-OBS performed, 45% (9 of 20) with PHN-EOG also had PHN-OBS, as opposed to only 4% (4 of 90) without PHN-EOG displaying PHN-OBS (p < 0.0001). We conclude that the prevalence of post-headshake nystagmus is increased in patients with either a unilateral caloric deficit or a history of true vertigo, and is best detected in the absence of vision.

The Relationship

Using a sample of 110 developed and developing countries for the period 1990-2004, the chapter claims that a small supply of tradable goods relative to their domestic absorption, and large foreign-exchange denominated debts towards the domestic banking system, denoted Domestic Liability Dollarization, are key determinants of the probability of Systemic Sudden Stop (3S). Moreover, the larger is financial integration, the larger is likely to be the probability of 3S; however, beyond a critical point the relationship gets a sign reversion.

At one time it was generally assumed, even by distinguished Byzantinists, that the Turkish conquest of Constantinople in 1453 put a sudden stop to the production of all objects of quality in the East Christian world, and that after that date Byzantine art at once degenerated into a peasant art throughout the whole of the area touched by the Turks. Recent research has, however, led to some modification of this view, and though work of the same superb quality as that produced in the great middle period of Byzantine art was not executed, we now know that in addition to painted icons, such things as embroideries, carved reliquaries, crosses of chased metal work or champlevé enamel and objects in bone or even ivory, were produced, which were by no means negligible from the artistic standpoint. Their production continued, moreover, through the sixteenth and earlier seventeenth centuries; only after that date did Christian art in Greece and the Balkans assume an essentially ‘peasant’ character. It is indeed to the sixteenth century that the greater number of painted icons that are now to be found in museums and private collections in Greece are to be assigned, and though there was much hack-work, paintings of very high quality were also produced amongst them.

Child’S Weight

Each year 1,000 children under the age of 5 are killed riding in automobiles and another 60,000 suffer disabling injuries. Crash protection does not mean holding a child on the lap of the parent. If an automobile strikes a solid object or comes to a sudden stop the unrestrained passenger continues forward at the rate of speed of the car until stopped by a surface within the vehicle or ejected through the windshield. The geometric increase of the child's weight would not allow the parent's arms to restrain the child.

Abstract An insulated container consisting of two ideal gas atoms are used. It is shown using rectilinear motion and elastic collisions with the walls of the container how the root mean square speed of the atoms change during acceleration of the container and after the container comes to a sudden stop.

The Right

This chapter looks at turns on the move with the right or left shoulder aligned with the corresponding ski. It distinguishes three important techniques that have gained currency in the world of sport. One of them pertains only to running skis while the other two require mountain skis with stable bindings. The first is the method for turning in place, used while descending from a mountain or over flat terrain on running skis, or on any skis that lack a stable binding and have a posterior center of balance. The next is the Christiania turn, which is carried out on the inner ski, that is, on the right ski when the turn is done to the right-hand side. Finally, the Telemark turn allows a skier to make a sudden stop as they are descending.
