The nature of the bright upstream end of jets as seen in VLBI images, known as the core, is difficult to specify because it is only weakly resolved on the images. Here the author discusses evidence indicating that the core is either where the optical depth is of order unity or a standing shock somewhat farther downstream. The jet at this point is turbulent, causing the polarization to be low an...

[1] The Hawaii Scientific Drilling Project recovered 3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than 1 km were deposited below sea level and contain considerable fresh glass. We report electron microprobe analyses of 531 glasses from the submarine section of the core, providing a high-resolution record of petrogenesis over ca. 200 K...

To confirm the effect of melatonin on 3-nitropropionic acid (3-NP)-induced striatal interneuron injury in rats, behavioral test, histology, immunohistochemistry and Western blotting were respectively used to characterize the behavioral changes of experimental animals in motor and cognition, the morphological changes of striatal interneurons and the expression level of protein markers induced by...

it’s very difficult to differentiate the brands for companies in these days. because branding is not just market share but also share in mind and share in heart that is the core of experiential marketing. in this research using a research model and applying sem and pls, the effect of experiential marketing on brand commitment with the mediating role of brand attachment, brand trust and brand lo...

Secondary protein structure carries information about local structural arrangements, which include three major conformations: alpha-helices, beta-strands, and coils. Significant majority of successful methods for prediction of the secondary structure is based on multiple sequence alignment. However, multiple alignment fails to provide accurate results when a sequence comes from the twilight zon...

BACKGROUND Infarct heterogeneity, as assessed by determination of the peri-infarct zone (PIZ) by cardiac magnetic resonance imaging, has been shown to be an independent predictor for the development of cardiac arrhythmias and mortality post myocardial infarction (MI). The temporal evolution of the PIZ post MI is currently unknown. Thus, the main objective of our study was to describe the tempor...

Endogenous neural stem cells become "activated" after neuronal injury, but the activation sequence and fate of endogenous neural stem cells in focal cerebral ischemia model are little known. We evaluated the relationships between neural stem cells and hypoxia-inducible factor-1α and vascular endothelial growth factor expression in a photothromobotic rat stroke model using immunohistochemistry a...

In diesem Artikel wird ein Re-Ranking-Ansatz für Suchsysteme vorgestellt, der die Recherche nach wissenschaftlicher Literatur messbar verbessern kann. Das nicht-textorientierte Rankingverfahren Bradfordizing wird eingeführt und anschließend im empirischen Teil des Artikels bzgl. der Effektivität für typische fachbezogene Recherche-Topics evaluiert. Dem Bradford Law of Scattering (BLS), auf dem ...

Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...
