Abstract

Using a data sample collected with the BESIII detector operating at the BEPCII storage ring at a center-of-mass energy of $\sqrt{s}=4.600$ GeV, we search for the production of $e^{+}e^{-} \to \phi\chi_{c0,1,2}$ and the charmonium-like state $Y(4140)$ in the radiative transition $e^{+}e^{-} \to \gamma Y(4140)$ with $Y(4140)$ subsequently decaying into $\phi J/\psi$. The processes $e^{+}e^{-} \to \phi\chi_{c1}$ and $\phi\chi_{c2}$ are observed for the first time, each with a statistical significance of more than 10\sigma, and the Born cross sections are measured to be $(4.2^{+1.7}_{-1.0}\pm 0.3)$ pb and $(6.7^{+3.4}_{-1.7}\pm 0.5)$ pb, respectively, where the first uncertainties are statistical and the second systematic. No significant signals are observed for $e^{+}e^{-} \to \phi\chi_{c0}$ and $e^{+}e^{-} \to \gamma Y(4140)$ and upper limits on the Born cross sections at $90\%$ confidence level are provided at $\sqrt{s}=4.600$ GeV.

Abstract

An observation term was carried on in an MBT plant owned and run by a public Company to treat MSW left by separate collection. All observations and measurements were made without interfering with the ordinary operation rules, in order to assess the efficiency of one process cycle for a given batch of waste. Analytical data came from both a) process instruments and b) physical analysis of a batch of waste entering / exiting from a selected bio-cell. From the process mass losses (about 37% – including moisture evaporation – in that single process cycle) the theoretical amounts of water and carbon dioxide produced by biodegradation were calculated. A verification of the results was tried through a thermal balance, comparing the energy released by degradation with the energy losses from the bio-cell. The results showed a fair agreement, within 80%; what appeared critical is the knowledge of the chemical composition of fermentable waste (taken as cellulose as first attempt) and the actual amount of heat developed by biological oxidation.

23. Low-velocity impact behaviour of fibreglass-aluminium laminates

Author

CAPRINO, GIANCARLO, SPATARO G, DEL LUONGO S., Caprino, Giancarlo, Spataro, G, and DEL LUONGO, S.

Abstract

Low-velocity impact tests were performed on fibreglass–aluminium composites made of 2024 T3 sheets and S2-glass/epoxy prepreg layers, using an instrumented falling weight machine. For comparison purposes, similar tests were carried out on monolithic 2024 T3 sheets of equivalent thickness. In the tests, the impact speed, mass, and energy were varied, to ascertain the influence of these parameters on the material response. From the results obtained, the overall force–displacement curve only depends on the impact energy, rather than on the mass and speed separately. Further, the energy required for penetration is higher for monolithic aluminium than for the fibreglass– aluminium. However, the latter material seems to offer better performance than carbon fibre- and glass fibre-reinforced laminates in terms of penetration energy, damage resistance, and inspectability. The main failure modes of fibreglass – aluminium were assessed by both ultrasonic C-scan and chemical grinding of aluminium sheets. It was found that the energy required for first failure is very low, whereas the energy level resulting in first fibre failure is similar to that inducing first cracking in the 2024 T3 sheets. From the experimental data, simple empirical relationships were found for the calculation of maximum contact force, energy, and residual displacement as a function of the maximum displacement.

Abstract

The epidemiology of HDV infection in Italy was assessed in a retrospective study involving 1556 HBsAg chronic carriers on their first presentation at one of the 35 Liver Units in 1987. Total anti-HD was detected in 23.4% of HBsAg carriers and was significantly more frequent in southern than in northern Italy (26.6% vs. 19.1%, p less than 0.01). Age distribution showed that 73% of the anti-HD-positive subjects, but only 56% of the anti-HD-negative subjects, were under 40 years of age (p less than 0.01). Anti-HD prevalence increased with the severity of the liver disease from 3.8% in healthy carriers to 42.5% in cirrhosis. No geographical statistical difference was found among HBsAg healthy carriers or subjects with chronic persistent hepatitis (CPH), while among patients with chronic active hepatitis (CAH) or cirrhosis anti-HD prevalence was much higher in the south (p less than 0.01). The various potential risk factors were evaluated by multiple logistic regression analysis. HDV infection was independently related to young age, residence in the south, i.v. drug abuse, a large family and household contact with an anti-HD-positive carrier. No association was found with blood transfusion or male homosexuality. These findings confirm that HDV infection is endemic in Italy, particularly in some southern areas, where intrafamily contact probably at a young age may favour the spread of the infection.

Abstract

The so called scimitar syndrome is a congenital malformation characterized mainly by the anomalous venous return of the right lung in inferior vena cava. Many structure of the lung may be involved. Usually lobation and bronchial distribution are abnormal, the right pulmonary artery is hypoplastic or absent, a partial anomalous artery from aorta (pulmonary sequestration) may be present, the entire lung is small and various degree of displacement of the heart to the right is detectable. Associated congenital heart defects may also be present. The name of the syndrome comes from the presence of this vessel (scimitar's sign) on routine chest x-ray. This paper describes the clinical and angiographic reports of four cases, which may represent, according a unique embriological interpretation, a different instances of this syndrome. The anatomic characteristic, the sign of scimitar, could be also absent, as in cases 2 and 3. In the case 2 there was complete absence of right pulmonary artery and in the case 3 a severe hypoplastic right pulmonary artery with unique small venous return in left atrium. The authors opinion is that all the anomalies of lung vascular connections, that result from interference with the normal growth of the lung bud, its separation from systemic vascular channels, and the establishment of the lesser circulation should be included. Because the different components of thie malformation can be present in various combination, the sign of scimitar is not pathognomonic to define the syndrome.

Abstract

Suicidality among migrants represents a multifaceted and complex issue with significant implications and challenges for public mental health and policies. This narrative review aims to explore the factors contributing to suicidality within the migrant groups, consequently highlighting the need for tailored interventions and supporting strategies. Firstly, we reviewed the evidences on the prevalence of suicidal ideation, attempted suicides, and deaths by suicide among migrants. The results were extremely heterogeneous, mostly depending on the different migrant group considered. Significant differences in suicide risk have been found depending on the legal status of migrants and their country of origin/migration. The second section explored the protective and risk factors for suicidal ideation and behaviours in different migrant groups. The analysis concluded that a set of factors may interact in various ways, contributing to a heterogeneous and complex framework underpinning the phenomenon of suicide. Migration itself may be a challenging and traumatizing experience, characterized by social isolation, cultural dislocation and adjustment, as well as economic and financial distress, all of which may exacerbate pre-existing mental health vulnerabilities or trigger new mental disorders. Acculturative stress, discrimination, and language barriers further compound these challenges, often hindering access to mental health services.

44. Prominence of the Instability of a Stabilizing Agent in the Changes in Physical State of a Hybrid Nanomaterial.

Author

Abstract

Shaping ability of hybrid nanomaterials is a key point for their further use in devices. It is therefore crucial to control it. To this end, it is necessary that the macroscopic properties of the material remain constant over time. Here, we evidence by multinuclear Magic-Angle Spinning Nuclear Magnetic Resonance spectroscopic study including 17 O isotope exchange that for a ZnO-alkylamine hybrid material, the partial carbonation of amine into ammonium carbamate molecules is behind the conversion from highly viscous liquid to a powdery solid when exposed to air. This carbonation induces modification and reorganization of the organic shell around the nanocrystals and affects significantly the macroscopic properties of the material such as it physical state, its solubility and colloidal stability. This study, straightforwardly extendable, highlights that the nature of the functional chemical group allowing connecting the stabilizing agent (SA) to the surface of the nanoparticles is of tremendous importance especially if the SA is reactive with molecules present in the environment., (© 2020 Wiley-VCH GmbH.)

Abstract

Surgical site infections are the second major cause of hospital acquired infections, accounting for a large part of overall annual medical costs. Airborne particulate is known to be a potential carrier of pathogenic bacteria. We assessed a mobile air particle filter unit for improvement of air quality in an operating room (OR). A new mobile air decontamination and recirculation unit, equipped with a crystalline ultraviolet C (Illuvia® 500 UV) reactor and a HEPA filter, was tested in an OR. Airborne particulate was monitored in four consecutive phases: I) device OFF and OR at rest; II) device OFF and OR in operation; III) device ON and OR in operation; IV) device OFF and OR in operation. We used a particle counter to measure airborne particles of different sizes: ≥0.3, ≥0.5, ≥1, ≥3, ≥5, >10 µm. Activation of the device (phases III) produced a significant reduction (p < 0.05) in airborne particulate of all sizes. Switching the device OFF (phase IV) led to a statistically significant increase (p < 0.05) in the number of particles of most sizes: ≥0.3, ≥0.5, ≥1, ≥3 µm. The device significantly reduced airborne particulate in the OR, improving air quality and possibly lowering the probability of surgical site infections., Competing Interests: Conflicts of interest: This study was partly funded by Aerobiotix Inc.

46. Nanocrystal-ligand interactions deciphered: the influence of HSAB and p K a in the case of luminescent ZnO.

Author

Champouret Y, Spataro G, Coppel Y, Gauffre F, and Kahn ML

Abstract

Despite all the efforts made by the scientific community to rationalize the interaction of organic molecules with nanocrystals (Ncs), we are still at the level of the empirical recipe when the material behavior in solution is concerned. In an effort to address this issue, the analysis of the luminescence measurements of ZnO Ncs in the presence of various organic substrates using a Langmuir adsorption model was carried out to determine for the first time the affinity constants and the number of binding sites as well as to rank the interaction strengths of these substrates with regard to ZnO Ncs. The results were confirmed by NMR spectroscopic studies, which, besides, provided a deep understanding of the substrate-ZnO Nc interactions. Analysis of the results using p K a and HSAB theory demonstrates that the interaction of a given substrate can be determined by its p K a versus the p K a of the organic molecules present at the surface of pristine Ncs and that the hard or soft character of the substrates can govern the emission intensity of the ZnO Ncs., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

Abstract

Background: Control of airborne microbial contamination is important in operating rooms (ORs). To keep airborne contamination low, guidelines should highlight the importance of air turnover. The aims of the study were: (1) to verify the association between air turnover and airborne contamination in ORs; and (2) to identify a statistical relationship between air turnover and airborne microbial contamination., Methods: A cross sectional study was carried out from November 2014 to July 2017 in the teaching Hospital of Siena. Nineteen ORs (14 with turbulent and 5 with laminar flow ventilation) were surveyed a total of 59 times under operating conditions. Air samples were collected with an air sampler. Petri dishes, incubated at 36 °C for 48 h, were used to quantify colony forming units in the samples (CFU). The data was transformed to evaluate several statistically significant nonlinear associations between air turnover, quantified as air changes per hour (ACH) and CFU per cubic meter of air (p < 0.05)., Results: A log-linear regression model provided the best fit between ACH and CFU for laminar (p = 0.013; R 2  = 0.3911) and turbulent flow systems (p = 0.002; R 2  = 0.3443). The corresponding model was: ln(CFU) = (a - b*ACH), where the regression parameters were estimated at a = 4.02 and b = 0.037 for laminar flow and a = 5.24 and b = 0.067 for turbulent flow., Conclusions: Italian guidelines indicate microbial load limits of 20 and 180 CFU/m 3 for operating rooms with laminar and turbulent flow ventilation, respectively. The model allowed us to evaluate the minimum number of ACHs to keep CFU within these limits. Ad hoc measurements in other environments can be used to calibrate the relationship between ACH and CFU., (Copyright © 2019 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Abstract

Background: The stethoscope is the most widely used instrument in healthcare. Studies have found similar rates of contamination on the stethoscope diaphragm and on physician fingertips after a single examination. Our aim was to test the effectiveness of an innovative portable device for disinfecting stethoscope membranes., Methods: From November 2016 to May 2017, a cross-sectional study was conducted in four wards of a private clinic: General Ward (GW), Internal Medicine Ward (IMW), Post-Operative Observation Ward (POW) and Permanent Vegetative State Ward (PVSW). Five wearable medical devices, designed to disinfect stethoscope membranes automatically by means of UV-C radiation, were provided to operators. Spot checks were made for microbial counts of stethoscope membranes, classified as treated or otherwise on the basis of whether they were found coupled or otherwise with the devices. The percentage reduction in colony forming units (CFU) was calculated between the two groups., Results: The number of tests of stethoscopes treated with the device was 116 out of 272. Untreated samples had a mean contamination of 132.2 CFU versus 6.9 CFU of treated samples: a 94.8% reduction (95% CI 91.3%-97.7). Highly significant statistical differences in CFU were found between untreated and treated membranes (p < 0.001). In particular, microbial contamination showed a reduction of 88.7% (CI 77.5%-96.05%) in PVSW, 95.9% (CI 88.2%-98.5%) in GW, 84.5% (CI 76.4%-90.5%) in IMW and 95.8% (CI 90.3%-98.1%) in POW., Conclusion: The devices proved effective and efficient in reducing the microbial load of stethoscope membranes. Wearing the device on the coat may act as a reminder of the need for hygiene., (Copyright © 2018 Australasian College for Infection Prevention and Control. Published by Elsevier B.V.
