Mortality in the l'aquila (central Italy) earthquake of 6 april 2009.

This paper presents the results of an analysis of data on mortality in the magnitude 6.3 earthquake that struck the central Italian city and province of L'Aquila during the night of 6 April 2009. The aim is to create a profile of the deaths in terms of age, gender, location, behaviour during the tremors, and other aspects. This could help predict the pattern of casualties and priorities for protection in future earthquakes. To establish a basis for analysis, the literature on seismic mortality is surveyed. The conclusions of previous studies are synthesised regarding patterns of mortality, entrapment, survival times, self-protective behaviour, gender and age. These factors are investigated for the data set covering the 308 fatalities in the L'Aquila earthquake, with help from interview data on behavioural factors obtained from 250 survivors. In this data set, there is a strong bias towards victimisation of young people, the elderly and women. Part of this can be explained by geographical factors regarding building performance: the rest of the explanation refers to the vulnerability of the elderly and the relationship between perception and action among female victims, who tend to be more fatalistic than men and thus did not abandon their homes between a major foreshock and the main shock of the earthquake, three hours later. In terms of casualties, earthquakes commonly discriminate against the elderly and women. Age and gender biases need further investigation and should be taken into account in seismic mitigation initiatives

The reasons of this trend are clear: contributing to a reduction of gas emissions and dependency on fossil fuels. Hydrogen-based devices are of particular interest due to their significant efficiency and reliability. Reforming technologies are among the most economic and efficient ways of producing hydrogen. In this paper we consider the regulation of hydrogen outflow in an ethanol steam reformer (ESR). In particular, a fast model predictive control approach based on a finite step response model of the process is proposed. Simulations performed using a more realistic non-linear model show the effectiveness of the proposed approach in driving the ESR to different operating conditions while fulfilling input and output constraints.Peer ReviewedPostprint (author's final draft

Compensation of Thermal Gradients Effects on a Quartz Crystal Microbalance

Quartz Crystal Microbalances (QCM) are widely used instruments thanks to their stability, low mass, and low cost. Nevertheless, the sensitivity to temperature is their main drawback and is often a driver for their design. Though the crystal average temperature is mostly considered as the only disturbance, temperature affects the QCM measurements also through the in-plane temperature gradients, an effect identified in the past but mostly neglected. Recently, it has been shown that this effect can prevail over that of the average temperature in implementations where the heat for thermal control is released directly on the crystal through deposited film heaters. In this study, the effect of temperature gradients for this kind of crystal is analyzed, the sensitivity of frequency to the average temperature gradient on the electrode border is determined, and a correction is proposed and verified. A numerical thermal model of the QCM has been created to determine the temperature gradients on the electrode borders. The frequency versus temperature-gradient function has been experimentally determined in different thermal conditions. The correction function has been eventually applied to a QCM implementing a crystal of the same manufacturing lot as the one used for the characterization. The residual errors after the implementation of the correction of both average temperature and temperature gradients were always lower than 5% of the initial temperature disturbance. Moreover, using the correlation between the heater power dissipation and the generated temperature gradients, it has been shown that an effective correction strategy can be based on the measurement of the power delivered to the crystal without the determination of the temperature gradient

Barnacle colonization of shoes: Evaluation of a novel approach to estimate the time spent in water of human remains

Estimating the time since death (minimum Post Mortem Interval, minPMI) is a necessary part of a forensic investigation. Besides considering the typical signs of death, minPMI can be estimated using the insects and other arthropods that colonize the remains (forensic entomology). In an aquatic environment, both insects and crustaceans may provide information regarding the time spent in water of the remains (minimum Floating Interval, minFI and minimum Post Mortem Submersion Interval, minPMSI), and this can also assist in determining the minPMI. Barnacles (Crustacea: Cirripedia) are common crustaceans that colonize solid substrates in marine environments and they can be found in association with organic and inorganic remains recovered from the sea. Barnacles colonize both floating and submerged remains and their growth rate is temperature dependent. Despite their potential to be indicative of the minFI and/or minPMSI, only a few case studies have considered it for this purpose, and scant research has been conducted in this field. Assuming that the vast majority of the bodies found in the sea are clothed, this research is focused on the barnacle colonization of two different types of shoes placed in the sea, in order to 1) identify the colonizing species in the chosen environment; 2) identify the settlement preferences of the barnacles associated with the shoes; and 3) determine the factors affecting the growth rate of the barnacles associated with the shoes. In April 2016 64 sport shoes (SS) and 64 patent leather shoes (PLS) were placed in the Boston Harbor (MA-USA) at 8/10 meters below sea level. Four of each shoe type were collected every two weeks for seven months. Individual barnacles from each shoe were sampled and measured to determine species and age. The overall colonization density and settlement preference was statistically analyzed. Results show that a) Amphibalanus improvisus (Darwin) (Crustacea: Cirripedia: Sessilia) colonized the vast majority of shoes; b) colonization occurred in less than 30 days and continued throughout the research period; c) a significant difference in colonization densities was found between the SS and PLS, with PLS seeing higher densities; d) barnacles showed preferential colonization of specific sections on both shoe types; e) barnacle growth was found to be significantly affected by water temperature and shoe type but not by the time spent in water; f) time spent in water and shoe type had a highly significant effect on the total number of barnacles per shoe, whereas water temperature did not

Synthesis of the presentation of INSPYRE results to the User Group

INSPYRE created a user group composed of key customers for the project’s results, which included representatives of the designers of the ESNII reactor concepts (ASTRID, MYRRHA, ALFRED, ALLEGRO), as well as of fuel manufacturers and utilities (ORANO, EDF). A first meeting had been organized in August 2018 to present the INSPYRE approach and activities to the users and discuss their needs in the area covered by INSPYRE activities. The synthesis of the meeting is reported in INSPYRE Deliverable D9.4. Three meetings with the user group were then organised throughout the project to present the approach and results of the project to the Users, get their feedback on these results and discuss follow-up activities. - The Second User Group meeting took place on January 17th, 2020 and was dedicated to the developments made in the fuel performance codes considered in the project and their assessment against the selected fast reactor irradiation experiments - The third User Group meeting was held on May 31st, 2021 and was dedicated to the simulation of the fuel elements in normal operating conditions of the ASTRID reactor concept - The final User Group meeting was organised jointly with the second Scientific Advisory Committee meeting on May 24th, 2022 and concerned the overall scientific outcomes of INSPYRE. The present deliverable reports the presentations made during the meetings and the synthesis of the exchanges that followed

Apparent digestibility of three diets in the Amiata breed donkey during lactation

The aim of the trial was to evaluate the apparent digestibility of three isonitrogenous and isocaloric diets for lactating donkeys: a diet with 8 kg of hay and 1.5 kg of commercial flaked mixed feed (CM) (Diet 1); a diet with 7 kg of hay and a 2.2 kg of CM (Diet 2) and a diet with 7 kg of hay, 1.5 kg of CM, 200 ml of corn oil and 0.2 kg of soybean meal (Diet 3). Four pluriparous donkeys (309±12 kg BW) at approximately 2-4 months of lactation were used. The trial was conducted according to a 3x3 Latin Square design with 1 or 2 subject per each cell. Feed and faeces samples were analysed for DM, OM, CP, EE, CF, NDF, ADF and gross energy. Acid insoluble ash was used as marker to calculate the apparent digestibility. The apparent digestibility of the main dietary components showed not significant differences among the three diets but generally they were lower in Diet 3. DM intakes of every diet exceeded the esti- mated energy requirement, whereas protein requirements were not significantly satisfied by Diet 1

Effect of different oils administration on oleic and linoleic serum profile in horses during standardised exercise test on treadmill

Because of its energy density, fat is often added to the diet for exercising horses; however, little attention has been given to the effect of dietary fatty acid composition. The aims of this study were to compare the effect of two diets containing different oils on the fatty acids haematic profile during and after an aerobic exercise test on treadmill. Four adult trained gelding Standardbred (mean BW=481±27 kg) were used in a two replicated 2x2 Latin Square design. Mixed hay-concentrate diets contained corn oil (CORN) or a mix of mono-di and triglycerides of olive oil (MDTO) were administrated. The horses received the diets for a period of four weeks. At the end of the adaptation period an aerobic exercise test on treadmill (30-min long) was carried on. Blood samples were collected at rest, after 15' and 30' of exercise and during recovery period (at 10', 30' and 60'). Serum fatty acid concentration was determined. MDTO supplemented horses showed an higher percentage of Oleic acid during and after the exercise test; whereas Linoleic acid showed a significant difference (P<0.05) between groups with the highest value at 10' and 30' after exercise in the CORN supplemented group

Synthesis of INSPYRE results

This document presents a synthesis of the results of the INSPYRE H2020 European Project, which was dedicated to the investigation and simulation of uranium-plutonium mixed oxide (MOX) fuels for fast reactors and their behaviour under irradiation. It first describes the progress in the understanding and description of the behaviour of MOX fuels obtained thanks to the combination of basic research (multiscale modelling and separate effect experiments) and examination of fuels irradiated in reactors in past experiments. Four operational issues were particularly studied: margin to fuel melting; irradiated fuel thermochemistry and interaction with the cladding; self-diffusion properties and inert gas behaviour; evolution of mechanical properties under irradiation. Second, the advances made in the simulation of fast reactor MOX fuels thanks to the development of more physically justified models and their implementations in three European fuel performance codes are presented. Then, the results of the simulation of two ESNII reactor cores are shown: normal operation conditions in the ASTRID sodium fast reactor prototype and normal and transient conditions in the lead-bismuth cooled reactor of the MYRRHA accelerator driven system. Finally, the activities conducted concerning education and training, dissemination, exploitation and communication are summarized
