The development of Fe73.5Si13.5B9Nb3Cu1 ~FINEMET! by Yoshizawa et al. and Fe88Zr7B4Cu1 ~NANOPERM! by Inoue et al. have shown that nanocrystalline microstructures can play an important role in the production of materials with outstanding soft magnetic properties. The FINEMET and NANOPERM materials rely on nanocrystalline a-Fe3Si and a-Fe, respectively, for their soft magnetic properties. The mag...

The ground state potential energy surface of the GeC2 molecule has been investigated at highly correlated coupled cluster levels of theory. Large basis sets including diffuse functions and functions to describe core correlation effects were employed in order to predict the true equilibrium geometry for GeC2. Like the much-studied valence isoelectronic SiC2, the linear ( (), L-shaped (A8), and T...

A 78-year old male previously diagnosed with a chronic pulmonary embolism experienced difficulty in breathing. Perfusion scan showed a segmental perfusion defect in the A6–8 area (Fig. 1A and B). Computed tomography could not reveal any massive thrombus in the major pulmonary artery. A pulmonary angiography was performed to detect abnormal lesions in the peripheral pulmonary artery. Rotation an...

Nocardia mediterranei produces the antibiotic rifamycin B, which belongs to the ansamycin group. The structure of rifamycin consists of the ansa chain and the chromophore. One part of this chromophore, the seven-carbon amino unit, which initiates ansa chain formation in ansamycins, has been identified as 3-amino-5-hydroxybenzoic acid. Kibby et al. 1] synthesized [carboxy-14C]3-amino-5hydroxyben...

Antiviral strategies targeting hijacked cellular processes are less easily evaded by the virus than viral targets. If selective for viral functions, they can have a high therapeutic index. We used RNA trans-splicing to deliver the herpes simplex virus thymidine kinase-ganciclovir (HSV-tk/GCV) cell suicide system into HIV-producing cells. Using an extensive in silico bioinformatics and RNA struc...

To a simple graph we associate so-called series, which can be viewed as the Hilbert–Poincaré series of certain infinite jet scheme. We study new q-representations and examine modular properties several examples including Dynkin diagrams finite affine type. Notably, obtain formulas for type A7 A8 in terms “sum tails” D4 D5 form indefinite theta functions signature (1,1). also related to sums pow...

in order to study different arrangements and weed controls effects on mung bean (vigna radiate l. wilczek) – black cumin (nigella sativa l.) intercropping an experiment was conducted at the research station of faculty of agriculture, ferdowsi university of mashhad, iran, during growing season 2005 – 2006. sixteen treatments comprising combinations of eight sowing patterns [a1: sole black cumin,...

PURPOSE The pathogenesis of pterygia is still not well understood. Recent studies suggest that it may be associated with inflammation and progressive proliferation triggered by ultraviolet radiation. In this study the authors determined that the inflammatory nature of pterygium is reflected in the protein components of tears. METHODS Consent for this study was obtained from 12 patients (avera...
