A case of pulmonary artery perforation by a flow-directed balloon-tipped catheter necessitated pneumonectomy. Predisposing conditions are discussed and conclusions made on the basis of this case and previous reports. The flow-directed balloon-tipped catheter has been widely used in cardiac surgical patients (Katz et al, 1977) in patients undergoing major surgical procedures and in emergencies f...

Over 160 cases of injury to the heart by pins and needles have been reported (Hermoni et al., 1986). These objects reached the heart by a number of routes including embolization and penetration from adjacent organs after ingestion. However the most common mode of injury was by direct transthoracic penetration and the majority of these were accidental in nature. We present the history of a 22-ye...

The aim of this paper is to present a streamlined and fully three-dimensional version of the quasicontinuum (QC) theory of Tadmor et al. [18, 19] and to analyze its accuracy and convergence characteristics. Specifically, we assess the effect of the summation rules on accuracy; we determine the rate of convergence of the method in the presence of strong singularities, such as point loads; and we...

We analyse the photodisintegration of nuclei near the center of blazars, in particular PKS 0528+134. We show that this process could explain the recent observation of a high Al/Si ratio in a cloud on the line of sight of a distant quasar and we calculate the effect of this gamma irradiation on the abundance of deuterium, an isotope of the highest cosmological interest since it is sensitive to t...

Highly purified HindIII restriction fragments of Xenopus laevis 5S DNA and of Psammechinus miliaris histone DNA have been covalently inserted into a derivative of phage lambda. This phage, genetically constructed by Murray et al. (1), contains only a single target for HindIII in the cI gene. Viable hybrid molecules were detected as clear plaque-forming phage after transfection of E. coli, the v...

It is shown, for the first time, that the transmittivity of wave guides created as rectilinear defects in periodic elastic band-gap materials oscillates as a function of frequency. The results are obtained using the finite difference time domain method for elastic waves propagating in two-dimensional inhomogeneous media. The oscillations of the transmittivity are due to the richness of modes in...

Technical Appendix Figure. Whole-genome, short-sequencing reads of Mycobacterium tuberculosis strain 4542 mapped to complete genome of reference strain H37Rv (NC_00962.3) by using Geneious 9.0 package: genome locus of spacers 7–9 in DR/CRISPR locus. Spacer numbers are given according to 43-spoligotyping (1). DR/CRISPR locus in M. tuberculosis is located on complementary strand, whereas spacers ...

one of the important subjects of comparative literature_ in french school_ is studying common contents between literature of different languages and separating literati’s initiatives and borrowing from other authors in the same or another language by them. with this aspect. using analytic – comparative metod, this study compares poems of abu tayyib al-muttanabbi_ as one of the most impressive a...
