BACKGROUND Airway collapse is a common finding in dogs with chronic cough, yet the diagnosis can be difficult to confirm without specialty equipment. HYPOTHESIS Bronchoscopic documentation of tracheobronchial collapse will show better agreement with fluoroscopic imaging than with standard radiography. ANIMALS Forty-two dogs prospectively evaluated for chronic cough. METHODS In this prospe...

The progressive collapse of the building structures due to accidents has become a hot research topic of civil engineering all around the world. The researches and designs on progressive collapse are based on accurately simulation for the failure process of whole structural systems. However, due to the complicated material and geometric nonlinearity and large computational workload in collapse s...

Bulk metallic glass alloys were processed into foam by several synthesis routes. These methods utilize the thermodynamic stability and thermoplastic formability of the supercooled liquid state to produce low-density homogeneous foams. The cellular structure is shown to evolve by growth of randomly distributed spherical bubbles towards polyhedral-like cells separated by microscopic intracellular...

To evaluate the potential utility of a self-expandable intratracheal nitinol stent with flared ends for the treatment of tracheal collapse in dogs, endotracheal stenting therapy was performed under fluoroscopic guidance in four dogs with severe tracheal collapse. During the 4 to 7 month followup, after stent implantation, clinical signs, including dyspnea and respiratory distress, dramatically ...

Background. Cardiac tamponade after cardiac surgical procedures is often associated with hemodynamically significant localized pericardial effusions. The localized collection of pericardial effusion in the postoperative period and the atypical presentation of cardiac tamponade limit the use of conventional clinical and echocardiographic signs usually seen with a circumferential pericardial effu...

Progressive collapse of building structures is generally triggered by a local failure due to accidental actions, followed by subsequent chain effect of the structures which may result in wide range failure or even collapse of the entire buildings. Since the “911” event, progressive collapse of building structures has been widely concerned by engineers and researchers. This paper assesses the cu...

To explore the collapse of eucalyptus wood cells during the drying process, continuous and intermittent drying were carried out on Eucalyptus urophylla. The shrinkage throughout the intermittent drying process was less than that of continuous drying. According to observations of cells made using scanning electron microscopy (SEM), there was a large difference in the degree of cell collapse betw...

This paper studies the gravitational collapse of a complex scalar Beld at the threshold for black hole formation, assuming that the collapse is spherically symmetric and continuously self-similar. A new solution of the coupled Einstein-scalar Beld equations is derived, after a small amount of numerical work with ordinary difFerential equations. The universal scaling and echoing behavior discove...

We review realistic models that reproduce quantum theory in some limit and yield potentially new physics outside that limit. In particular, we consider deterministic hidden-variables theories (such as the pilot-wave model) and their extension to “quantum nonequilibrium,” and we consider the continuous spontaneous localization model of wave function collapse. Other models are briefly discussed.

In view of the increasing advances in our knowledge of pulmonary tuberculosis it is indeed timely that we should, while none the less maintaining a progressive outlook, 'go wisely and slow-they stumble that run faster.' In other words, we should now pause to assess the situation in so far as the position of artificial pneumothorax in the sphere of collapse therapy is concerned, and ask ourselve...
