Reconstruction was performed using only a rectus abdominis musculocutaneous flap. No patient developed circulation problems in the flap or severe flail chest, and we had successful results in ...

A core structure comprising a plurality of graphite blocks with coolant channels is designed so that misalignment of the channels due to irradiation is prevented even in the case of both growth and shrinkage. The structure has tubular spacers between adjacent pairs of blocks, the cers being disposed in mutually perpendicular directions in ...

This is the most common of the bifascicular blocks. RBBB is most easily recognized in the precordial leads by the rSR' in V1 and the wide S wave in V6 (i.e., terminal QRS forces oriented rightwards and anterior). LAFB is best seen in the frontal plane leads as evidenced by left axis deviation (-50 degrees), rS complexes in II, III, aVF,and the small q in ...

An experimental investigation into the behavior of unreinforced, ungrouted concrete block masonry walls subjected to repeated in-plane cyclic displacements was undertaken. A total of 15 walls were tested of which 10 were 64 in. x 64 in. planar walls and 5...

A solid moderator core structure is designed for gascooled graphite- moderated reactors. The structure comprises an assembly of spaced vertical columns of graphite blocks within a constrained framework. The columns are divided into static columns and dynamic columns in which clocks can move vertically. The columns are arranged so that each dynamic column is ...

The skeletal muscle relaxant properties of an aqueous extract of Portulaca oleracea were examined on the twitch and tetanus tension evoked by electrical stimulation using the rat phrenic nerve-hemidiaphragm and frog sciatic nerve-sartorius muscle preparations and on contractures induced by nicotinic agonists using the rat rectus abdominis muscle preparation. The extract (5-50 ...

This patent describes a location method for locating unknown location ultrasonic reflectors in three dimensions in a rotor using a transducer in a bore of the rotor. It comprises the steps of: recording calibration transit times of an ultrasonic wave reflected from holes located at known axial, radial and circumferential positions in a calibration block having a diameter, ...

The combination of left bundle-branch block with right ventricular hypertrophy is said to be exceptional. Faced with this possibility, many authors consider a diagnosis of right ventricular hypertrophy as impossible. The two cases reported were found in a total of approximately 10,000 vectorcardiograms. Starting in 1950, Laham drew attention to the special morphology of ...

In order to increase the strengih of moderator blocks and to economize material the blocks are machined starting from a cylindrical rod. The rod has a diameter slightly smaller than that of the cylinder passing through the longitudinal edges of the virtual prism that would forra with sirailar ones a lattice without interspaces having the desired ...

A multi-spectral detection system for detecting radiation within frequency bands that are in diverse portions of the electromagnetic spectrum is disclosed. The preferred embodiment is a cassegrain system including a primary reflector for reflecting radiant energy in the radio frequency and infrared portions of the electromagnetic spectrum; a subreflector positioned along the axis of the primary ...

This is an interactive homework problem for introductory physics students relating to tension forces in a system featuring an incline plane with a 30-degree angle, two blocks of known mass, and an ideal pulley. Students are required to determine the acceleration of the block moving up the incline. A user-activated "help" sequence is ...

We present epitaxial structures made of twin nickel blocks with perpendicular magnetic anisotropy separated by a copper layer which, for some values of this interleaving layer, show domain structures with four levels of contrast in magnetic force microscopy images. This manifold domain structure implies that the magnetization in the Ni blocks, in addition ...

An order-order transition (OOT) from the bicontinuous double-gyroid (G)structure to the hexagonally-packed cylindrical (C) structure in a poly(styrene-block-isoprene) (SI) block copolymer was investigated by transmission electron microtomography (TEMT). The coexistence of the G and C microdomains during the OOT was observed. The boundary structures between ...

In a differential laser gyro system including a ring laser in the form of a figure eight incorporated in a solid block, optical readout is accomplished by mounting the readout optics to the block in a manner similar to that employed for the laser optics. The laser optics comprises four mirrors mounted on the outer face of the block, ...
