The purpose of this chapter is (i) to describe some currently available analytical methods for using individual level epidemiological data to estimate the impact of multiple risk factor interventions on health and (ii) to carefully review the conditions under which these methods deliver unbiased estimates of impact. The chapter is organized as follows. In sections 2 and 3, we discuss estimation...

In this paper, we perform a detailed study of the spectral response of the gold U-shaped nano-structures for different geometrical parameters and polarizations in order to obtain significant localization factor in the wavelength 1.55 μm. The obtained near-field distribution of electric fields reveals that resonances in these nano-structures correspond to the even and odd plasmonic modes dependi...

based on, historical seismicity, position of 19-century instrumental epicenters, fault zones, relation of seismicity with active faults, and structural geology, statistics of earthquake activites, model studies for estimation of acceleration, and other information of intensities of iranian earthquakes, and for simplicity in the usage, the country is divided into two intensity provinces. in the ...
