A Hohlraum-like configuration is proposed for realizing a simple compact source for neutrons. A laser pulse enters a tiny thin-shelled hollow-sphere target through a small opening and is self-consistently trapped in the cavity. The electrons in the inner shell-wall region are expelled by the light pressure. The resulting space-charge field compresses the local ions into a thin layer that become...

Bochdalek hernia occurs from a congenital defect of the diaphragm, allowing the passage of abdominal structures into the thoracic cavity, limiting lung expansion and ventilatory function. Bochdalek hernia is common in neonates but rarely occur in adults; there are only 4 documented cases in the elderly population. We present a case of an 88-year-old woman with severe hypoxia and respiratory fai...

We have carried out a 3D ideal-MHD (Magnetohydrodynamic) simulation to study the evolution of laser generated plasma plume in moderate external magnetic field (0.13 T) oriented perpendicular flow direction plume. The shows that pushes lines outward expansion. This leads compression and bending lines.The force resulting from change shape density opposes expansion An elliptic layer shocked is for...

Rotationally-resolved spectra of the m16 band of 1,3,5-trioxane, centered near 1177 cm 1, have been obtained via cavity ringdown spectroscopy using a continuous-wave external-cavity quantum cascade laser and a slit expansion nozzle. 219 transitions were identified and fitted to determine the excited state rotational constants for this band. In addition to fundamental interest, these data could ...

INTRODUCTION Pleural empyema is a severe complication of various diseases. The essential is the inserting a drain into the pleural cavity and evacuation of the pus. Sometimes the pus is very thick and its evacuation and re-expansion of the lung is very difficult. METHODS We report a group of 10 patients with intrapleural administration of Pulmozyme (dornase alpha) in dosages of either 2.5 mg ...

We evaluate the finite-temperature Euclidean phase-space path integral for the generating functional of a scalar field inside a leaky cavity. Provided the source is confined to the cavity, one can first of all integrate out the fields on the outside to obtain an effective action for the cavity alone. Subsequently, one uses an expansion of the cavity field in terms of its quasinormal modes (QNMs...

Fish typically use a rostro-caudal wave of head expansion to generate suction, which is assumed to cause a uni-directional, anterior-to-posterior flow of water in the expanding head. However, compared with typical fish, syngnathid fishes have a remarkably different morphology (elongated snout, small hyoid, immobile pectoral girdle) and feeding strategy (pivot feeding: bringing the small mouth r...

We present an accurate and efficient method of modeling second-harmonic generation in two-dimensional structures by use of eigenmode expansion. By using the undepleted-pump approximation we uncouple the calculations for the fundamental and second harmonic. Expansion of the field in eigenmodes gives rise to a linear matrix formalism. The method includes reflections and is especially suited for p...
