This paper presents evaluation of a plan for surveillance of and controlling the effects of heat-related mortality (PSCEHW), implemented in Madrid in 2004 through a time series analysis conducted with ARIMA modeling. From the public health point of view, prevention plans should be implemented as adaptive measures to heat waves. In 2003, the impact attributable to the heat wave was an increase i...
In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...
We show that the radiative heat transfer between two solid surfaces at short separation may increase by many order of magnitude when the surfaces are covered by adsorbates. In this case the heat transfer is determined by resonant photon tunneling between adsorbate vibra-tional modes. We propose an experiment to check the theory. It is well known that for bodies separated by d >> d T = c¯ h/k B ...
BACKGROUND As a result of climate change, the frequency of extreme temperature events is expected to increase, and such events are associated with increased morbidity and mortality. Vulnerability patterns, and corresponding adaptation strategies, are most usefully conceptualized at a local level. METHODS We used a case-only analysis to examine subject and neighborhood characteristics that mod...
Like other extreme weather events, heat waves are likely to occur more frequently worldwide as a consequence of climate change, and their impacts are likely to be borne disproportionately by developing countries. However, detailed data on health outcomes for developing countries over a sufficient period of time are not readily available. Instead, we use monthly panel data for more than 3000 U.S...
We examine the role of Alfvén wave damping in heating the plasma in the magnetic funnels of magnetospheric accretion models of young stars. We study four different damping mechanisms of the Alfvén waves: nonlinear, turbulent, viscous-resistive and collisional. Two different possible origins for the Alfvén waves are discussed: 1) Alfvén waves generated at the surface of the star by the shock pro...
The non-Fourier effect in heat conduction is important in strong thermal environments and thermal shock problems. Generally, commercial FE codes are not available for analysis of non-Fourier heat conduction. In this study, a meshless formulation is presented for the analysis of the non-Fourier heat conduction in the materials. The formulation is based on the symmetric local weak form of the sec...
Long-range forecasting of heat/cold waves is a topical issue nowadays. High computational complexity of numerical and statistical models’ design is a bottleneck for the forecast process. In this work, Windows Server 2012 R2 virtual machines are used as a high-performance tool for the speed-up of the computational process. Six D-series and one standard tier A-series virtual machines were hosted ...

The occurrences of extreme weather, particularly heat-waves can often result in significant costs in terms of human health, damage to infrastructure, increased stress of natural ecosystems and reduced economic activity. In Australia, temperature extremes, producing intermittent heat-waves silently kill almost as many people as do any other natural disasters (Granger and Berechree 2005). While t...
