An easily integrable industrial system for gamma spectroscopic analysis and traceability of stones and building materials

In the building material and stones market, lots of restrictions are coming in different world zones. In Europe, a recent regulatory set up the maximum level of radiological emissions for materials intended for use in public and private building structures. For this reason, companies need to have a very efficient radiological measurements system in their production chain, in order to respect all the rules and to be competitive in the world market. This article describes CORSAIR, a Cloud-Oriented Measurement System for Radiological Investigation and Traceability of Stones. Our cyber-physical system consists of sensing nodes network connected to a data collection gateway through LoRaWAN protocol, and interfaces with a centralized cloud application. CORSAIR introduces a fast, repeatable, real-time and non-destructive method to measure radiological emissions and other parameters of each single building material item, uniquely identified by an applied RFID tag. The validity of this system is confirmed by in-situ measurement campaign compared with high-precision laboratory analysis. The results demonstrate the accuracy of the CORSAIR sensor and the possibility to easily integrate it in the company production chain without any change

Prevention of cardiovascular events in early menopause: a possible role for hormone replacement therapy

Heart disease is a major cause of illness and death in women. It is well known that there is an increase in cardiovascular disease and cardiovascular risk factors after the menopause, but it is still unclear whether the change in risk factors after the menopause is only related to the aging process or is principally due to estrogen deprivation. Observational studies suggest a protective role for estrogens, whereas recent randomized controlled trials report a negative effect of oral estrogens on primary and secondary prevention of cardiovascular events. The role of inflammation in the process of atherogenesis and in determining the cardiovascular disease risk in postmenopausal women has been focused only recently as well as the role of the estrogen receptor system in different tissues and the role of genetic susceptibility to adverse events during estrogen therapy. The objective of this work was to review the current understanding of the relationships between cardiovascular disease risk factors and hormonal age-related changes in postmenopausal women and particularly in early and surgical postmenopausal women, for a more appropriate evaluation of the expected effects of therapy with exogenous estrogens in a specific sample of the large population of postmenopausal women

Mini nutritional assessment (short form) and functional decline in older patients admitted to an acute medical ward

BACKGROUND AND AIMS: Protein and/or energy malnutrition is common in hospitalized older patients and is associated with poor outcomes. Among recommended nutritional screening tools, contrasting data exist about the usefulness of the Mini Nutritional Assessment Short-Form (MNA-SF). We evaluated whether the MNA-SF, alone or integrated with serum albumin levels, is a reliable predictor of functional decline in older patients. METHODS: We studied 275 elderly patients (mean age 76.5, 60.7% males) admitted to an acute medical ward of a tertiary-care teaching hospital over a 12-month period. In this observational study, we evaluated nutritional status, with the MNA-SF alone or integrated with albumin. Data were collected at admission and related to laboratory and geriatric assessment features, and length of stay (LOS). Functional decline (defined as a loss >or=10% in terms of Barthel Index score at discharge compared with 2 weeks before admission) was considered as outcome. RESULTS: The MNA-SF estimated 46% patients at risk of malnutrition. These subjects had worse clinical features (lower total cholesterol and albumin levels), longer LOS (13.3 vs 11.2 days, p=0.014) and considerable functional decline (OR 4.25, 95% CI 1.83-9.9, p=0.001). Integrating the MNA-SF with albumin values, we obtained an effective instrument to detect older inpatients with protein-energy malnutrition, at higher risk of undergoing functional decline (OR 16.19, 95% CI 4.68-56.03, p<0.0001). CONCLUSIONS: The MNA-SF is a useful screening tool for hospitalized elders at risk of malnutrition. It is associated with poor clinical outcomes and is able to predict functional decline. Together with hypoalbuminemia, it better identifies patients with true protein-energy malnutritio

2.5‐ MeV

A laptop neutron source suited for the most demanding field or laboratory applications is presented. It is based on laser ablation of CD2 primary targets, plasma acceleration of the D+ ions, and their irradiation of secondary CD2 targets. The deuterium–deuterium (D-D) fusion reaction is induced in the secondary target, according to the values of fusion cross-section versus deuteron energy, which show a significant probability also at relatively low ion energies. The experiments were completed in the PALS laboratory, Prague, detecting monoenergetic neutrons at 2.45 MeV with an emission flux of about 109 neutrons per laser shot. Other experiments demonstrating the possibility to induce D-D events were performed at IPPLM, Warsaw, and at INFN-LNS, Catania, where the deuterons were accelerated at about 4 MeV and 50 keV, respectively. In the last case, a low laser intensity and a post-ion acceleration system were employed. A special interaction chamber, under vacuum, is proposed to develop a new source of monochromatic neutrons or thermalized distribution of neutrons
