EPR and Time Resolved EPR of synthetic eumelanins
Eumelanins are the fundamental components of the mammalian pigmentary system. Their
biological functions, in all the different localization, e.g. the skin or the retinal pigment epithelium,
are influenced by uncommon physicochemical features [1]. Eumelanin properties include a
permanent EPR signal due to a number of intrinsic quinone/semiquinone like radicals and a
reversibly generated EPR signal under UV and visible irradiation, that suggests the formation of
additional extrinsic radicals. Recently, TR-EPR studies have demonstrated that in the
photoproduction of new melanin free radicals, they are generated as Radical Pairs from the triplet
manifold [2]. Here, we compare photoreactivity of a synthetic eumelanins as function of the
temperature in the range 290-140K. Moreover, we analyze the electron spin polarization of the EPR
signal in the presence and in the absence of oxygen. TR-EPR spectra of samples under vacuum
exhibit only a net emission after the exciting laser pulse, while for sample in equilibrium with
oxygen in the air an additional distinct pattern consisting of an enhanced absorption followed by
emission is present at the earliest times (delay<1ms). It is possible that the spin photochemistry of
melanin determines its observable photoreactivity
Seasonality in Site Response: An Example from Two Historical Earthquakes in Kazakhstan
During the past 150 yr, the city of Almaty (formerly Verny) in Kazakhstan has suffered significant damage due to several large earthquakes. The 9 June 1887 Mw 7.3 Verny earthquake occurred at a time when the city mainly consisted of adobe buildings with a population of 30,000, with it being nearly totally destroyed with 300 deaths. The 3 January 1911 Mw 7.8 Kemin earthquake caused 390 deaths, with 44 in Verny itself. Remarkably, this earthquake, which occurred around 40 km from Verny, caused significant soil deformation and ground failure in the city. A crucial step toward preparing for future events, mitigating against earthquake risk, and defining optimal engineering designs, involves undertaking site response studies. With regard to this, we investigate the possibility that the extreme ground failure observed after the 1911 Kemin earthquake could have been enhanced by the presence of a shallow frozen ground layer that may have inhibited the drainage of pore pressure excess through the surface, therefore inducing liquefaction at depth. We make use of information collected regarding the soil conditions around the city at the time of the earthquakes, the results from seismic noise analysis, borehole data, and surface temperature data. From these datasets, we estimated the necessary parameters for evaluating the dynamic properties of the soil in this area. We successively characterize the corresponding sediment layers at the sites of the observed liquefaction. Although the estimated soil parameters are not optimally constrained, the dynamic analysis, carried out using selected strong‐motion recordings that are expected to be compatible with the two considered events, indicated that the extensive ground failure that occurred during the Kemin event could be due to the presence of a superficial frozen soil layer. Our results indicate that for this region, possible seasonal effects should, therefore, be considered when undertaking site effect studies
A citizen science approach for supporting rapid earthquake impact assessments (International Journal of Disaster Risk Reduction)
After a strong earthquake, the rapid identification of the extent of the affected area is the most crucial task of civil protection authorities. The information provided by those directly affected by an event makes the difference since it offers the opportunity to take advantage of direct observations and, in the case alert systems are available, to verify if they worked properly. Thanks to the fruitful collaboration between the Regional Civil Protection of Friuli Venezia Giulia and the National Institute of Oceanography and Applied Geophysics – OGS in Italy, a procedure for collecting rapid information about the impact of an earthquake using an expert crowdsourcing approach has been in place for some years. The volunteers of the civil protection, appropriately trained, upon receipt of the seismic event notification, are asked to rapidly compile a specific questionnaire, describing the impact of the event. Data are rapidly coded, and the results are summarized in a seismic impact map showing the effect of the earthquake throughout the territory in a simplified way. This map complements the impact estimation provided by the analysis of recorded shaking data. This paper describes the results obtained by analyzing the “Trained Volunteers Seismic Evaluation” questionnaire (TVSE) completed by volunteers for some of the most significant events in recent years
