The heart of hibernating species is resistant to lethal ventricular fibrillation (VF) induced by hypothermia. Spatially discordant (SDA) cardiac alternans is a promising predictor of VF, yet its role in the mechanism of hypothermic arrhythmogenesis in both nonhibernating and hibernating mammals remains unclear. We optically mapped the posterior epicardial surface of Langendorff-perfused hearts ...

BACKGROUND Spatially discordant alternans (SDA) has been linked to life-threatening arrhythmias. The mechanisms underlying SDA development in cardiac tissue remain unclear. METHODS AND RESULTS We investigated the role of conduction velocity (CV) restitution and short-term memory in the organization and evolution of alternans in action potential duration using high-resolution optical mapping o...

AIM To review the role of multidisciplinary management in treating sporadic duodenal adenomas (SDA). METHODS SDA managed at North Shore Hospital between 2009-2014 were entered into a prospective database. Pathology, endoscopic and surgical management as well as follow up were reviewed. RESULTS Twenty-eight patients (14 male: Median age 68 years) presented with SDA [18 were classified as non...

Concrete durability, especially in water-logged environments might not be possible with conventional constituents of concrete. A combination mineral and chemical admixtures different proportions is used to study water absorption, sorptivity, permeability behavior The test were carried out using nine (9) trial mixes Calcined Clay (CC), Sawdust Ash (SDA), Crystalline Based Admixture (CBA), Superp...

There are some reports about the risk of manipulating wild hedgehogs since they can be reservoirs of potential zoonotic agents like dermatophytes. The aim of this study was to describe the integument mycobiota, with special attention to dermatophytes of wild European hedgehogs. Samples from spines and fur were cultured separately in Sabouraud dextrose agar (SDA) with antibiotic and dermatophyte...

Domain-specific languages improve the productivity of application engineers by raising the level at which they define domain instances. However, more support for designing and implementing these languages in practice is needed. The Software Design Automation (SDA) method is a specific approach for doing domain-specific language design and implementation based on a principled, semantics-based ap...

Solar photovoltaic power generation has become the focus of world energy market. However, weak continuity and variability solar data severely increase grid operating pressure. Therefore, it is necessary to propose a new refined targeted forecasting method broaden channels. In this paper, hybrid model (KM-SDA-ABWO-RBF) based on radial basis function neural networks (RBFNNs), adaptive black widow...

abstract in this paper,using a structural decomposition analysis (sda) and the latest available input-output tables we investigate the sources of labor productivity growth in norway, south korea and iran. then, the contribution of each source in the growth of labor productivity is discussed. the results show that among six factors, value added coefficient is the most influencing factoracross al...

This study shows that some species of fungi are affected by the magnetic field, which should be taken into account in studies airborne fungal and air quality. The aim this paper was to evaluate effect oscillating field (OMF) on behavior colonies three genus growth different culture mediums. stains were: Aspergillus niger, Cladosporium cladosporioides Penicillium citrinum were inoculated 90 mm P...

The germanosilicate ITQ-24 (IWR framework type) was synthesized in fluoride medium using 1,3,5-tris(1,2-dimethylimidazolium) benzene as the structure directing agent (SDA). A structure analysis of the as-synthesized ITQ-24 material using synchrotron powder diffraction data and difference electron density calculations have allowed the fluoride ions and the germanium atoms to be located and the c...
