Two days later he felt discomfort in the chest and a skiagram showed re-accumulation of fluid in the right pleural cavity, and obliteration of the left costo-phrenic angle. Bilateral pleural drainage tubes were inserted and 3300 ml. of thin, whitish fluid on the right side, and 800 ml. of blood stained fluid on the left side were obtained on the first day. The left sided tube drained minimal am...

OBJECTIVE To investigate whether the low-tube-voltage (80-kVp), intermediate-tube-current (340-mAs) MDCT using the Iterative Reconstruction in Image Space (IRIS) algorithm improves lesion-to-liver contrast at reduced radiation dosage while maintaining acceptable image noise in the detection of hepatocellular carcinomas (HCC) in thin (mean body mass index, 24 ± 0.4 kg/m(2)) adults. SUBJECTS AN...

The steady state non-Newtonian flow, with strain rate dependent viscosity in a thin tube structure, no slip boundary condition, is considered. Applying the Banach fixed point theorem we prove existence and uniqueness of solution. An asymptotic approximation constructed justified by an error estimate.

Plate fin-tube heat exchangers are widely used in air conditioning and refrigeration systems other industry fields. Various errors made the manufacturing process can result formation of an gap between tube fin. Several numerical simulations were carried out for a symmetric section plate exchanger to study influence on transfer under periodic flow conditions. Different locations sizes spanning 1...

Secondary enhancement effects are well understood and accounted for in quantitative analysis of homogeneous bulk specimens and thin films in the conventional energy range. The “conventional energy range” is closely related to the spectral distribution of the primary radiation (generally from an x-ray tube), which extends with useful intensities roughly from a few keV to about 30-60keV depending...

(2) A thin acrylic plate is rigidly attached to this tube in such a way that the lumen of the tube opens onto the upper surface of the plate. This plate (8 mm. in diameter and approximately circular in outline) is curved to fit and firmly sutured to the sclera. When covered by a flap of conjunctiva and Tenon's capsule, the plate forms the floor of a blel) wvhich is in free communication with th...

Entangled networks of stiff biopolymers exhibit complex dynamic response, emerging from the topological constraints that neighboring filaments impose upon each other. We propose a class of reference models for entanglement dynamics of stiff polymers and provide a quantitative foundation of the tube concept for stiff polymers. For an infinitely thin needle exploring a planar course of point obst...
