OBJECTIVES The aim of this study was to determine ultraviolet (UV) action spectra for cell killing of primary porcine lens epithelial cells (LECs) that can be used to establish guidelines for evaluation of the hazard of cataract due to UV exposure in the workplace. METHODS Primary porcine LECs were exposed to different doses (radiant exposure) of UV at 17 different wavelengths from 235 nm to ...

The purpose of this paper is to develop the argument that sentiments (including moral sentiments) are endemic to the building of knowledge about the economy, as well as the functioning of the economy itself. This contrasts with the mainstream treatment of sentiment as separable from rationality, such that it is seen (if at all) as requiring an ex post modification of rational choice theory. The...

Probabilistic Seismic Hazard Assessment (PSHA) was carried out for the administrative region of Attica (Greece). Peak Ground Acceleration (PGA) and Velocity (PGV) values were calculated return periods 475 950 years five sub-areas covering entire region. PGA hazard curves Uniform Spectra (UHS) in terms spectral acceleration (Sa) generated Athens, Methana, capitals each island (Salamina, Aegina, ...

Prevalent cohort studies are commonly conducted in many areas of research when incident deemed infeasible due to logistic or other constraints. While such cost effective, it is known that survival data collected on prevalent cases do not form a representative sample from the target population. When incidence (e.g. onset disease) arise stationary Poisson process, allows developing more efficient...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

ZnO nanorods (NRs) were synthesized using an in situ low-temperature hydrothermal method. In order to investigate the effect of different seed layers on quality of ZnO NRs arrays, alcoholic, alkaline and acidic seed solutions were deposited by spin coating on ITO-glass substrate. Experimental results revealed that the vertically ZnO NRs obtained from monoethanolamine-based seed layer is the...
