- Abstract
Paleoclimate and paleoenvironmental stratigraphic reconstructions from temperate glaciers are hindered by surface melting and ice metamorphism, which cause mobilization and concentration of impurities, as well as their interaction through englacial reactions. Despite meltwater intrusions, other impurities such as pollen grains and other palynomorphs remain to their original depth of deposition thanks to their large grain size. Temperate glaciers close to vegetated areas, therefore, can include palynomorphs of different types that i) can be reliable annual markers for ice-core dating and, ii) allow reconstructing paleoenvironmental changes through time. The Adamello Glacier (Central Alps, Italy) is a temperate glacier that extends over ca 14.35 km2 (2020) at elevations ranging between 2560 and 3420 m a.s.l. In the framework of the CLIMADA Project, a 224 m long ice core (ADA 270) was recovered in 2021 from Pian di Neve, the summit plateau at about 3200 m a.s.l. in the accumulation area of the glacier. Preliminary estimates date the surface ice of the glacier to the 1980s while the bottom of the core might be Medieval in age. Radionuclide-based dating (3H, 14C, 137Cs, 210Pb) is in progress. The multiproxy approach adopted in this study includes black carbon, dust grain size and mineralogy, oxygen and hydrogen stable isotopes and palynomorphs, these last being the main object of this work. Given the site location, the palaeoecological signal is believed to be of regional significance. Despite the stratigraphy may not be preserved for some soluble chemical species, the core contains a high variety of palynomorphs, which allow the reconstruction of palaeoenvironmental and paleoclimatic variations at subannual resolution. The mean ice accumulation rate is about 0.9 m w.eq. yr-1. Consequently, the mean sampling resolution adopted for the palynomorph study is 0.1 m, increased to 0.01 m in specific intervals. Palynomorphs are mainly found in layers representing the spring-sum

- Abstract
Introduction: The International Commission for Mountain Emergency Medicine (ICAR MedCom) developed updated recommendations for the management of avalanche victims. Methods: ICAR MedCom created Population Intervention Comparator Outcome (PICO) questions and conducted a scoping review of the literature. We evaluated and graded the evidence using the American College of Chest Physicians system. Results: We included 120 studies including original data in the qualitative synthesis. There were 45 retrospective studies (38%), 44 case reports or case series (37%), and 18 prospective studies on volunteers (15%). The main cause of death from avalanche burial was asphyxia (range of all studies 65–100%). Trauma was the second most common cause of death (5–29%). Hypothermia accounted for few deaths (0–4%). Conclusions and recommendations: For a victim with a burial time ≤ 60 minutes without signs of life, presume asphyxia and provide rescue breaths as soon as possible, regardless of airway patency. For a victim with a burial time > 60 minutes, no signs of life but a patent airway or airway with unknown patency, presume that a primary hypothermic CA has occurred and initiate cardiopulmonary resuscitation (CPR) unless temperature can be measured to rule out hypothermic cardiac arrest. For a victim buried > 60 minutes without signs of life and with an obstructed airway, if core temperature cannot be measured, rescuers can presume asphyxia-induced CA, and should not initiate CPR. If core temperature can be measured, for a victim without signs of life, with a patent airway, and with a core temperature < 30 °C attempt resuscitation, regardless of burial duration.

- Abstract
Ice-covered surfaces of the planet are a pristine glimpse on the climate history of the Earth. Their capability to reflect the solar radiation affects the energy budget through time, so that paleoclimatic information recorded in polar and mountain glaciers tell a story about climate and environmental changes. Climate variations are a glaring reality due to a progressive climate warming that has been observed since the 1950s. The latest 2022 IPCC report [1], highlights the worrying state of the entire cryosphere health. Mid-latitude glaciers, e.g., are highly sensitive to the current atmospheric warming, which is seriously compromising the quality of the signal preserved in the ice. Mineral dust aerosol in atmosphere can alter the Earth’s energy budget interacting with the solar electromagnetic radiation. The dust settled on glaciers surfaces varies the ice capability to reflect the incident radiation, so that a major portion of it is absorbed as a function of Light Absorbing Impurity (LAI) concentration, mineralogical composition, LAI shapes etc. Depending on formation sites different minerals have different optical properties, affecting cryosphere mechanisms in a way that has to be further investigated. Ice core studies from mid-latitude mountain glaciers are essential to infer recent climate variability and anthropogenic impact on a regional scale. In the scientific literature, various imaging non-destructive systems extract e.g. information from visual stratigraphy of ice cores [2]. Advanced techniques can further be developed to improve the accuracy of ice cores measurements, pursuing the preservation of such precious achieves. The aim of this work is to apply different approaches to improve the understanding and climate simulation models regarding ice optical properties and feedback mechanisms, focusing on mineral dust and ice internal features. First, a non destructive system based on a hyperspectral imaging sensor is used to analyze optical properties of ice

- Abstract
Mineral dust aerosol plays an important role in climate and biogeochemical processes by providing nutrients to marine and terrestrial ecosystems and by influencing the radiation balance of the atmosphere. In turn, mineral dust responds to natural and anthropogenic alterations of land cover and land use resulting from several environmental changes that occurred on different timescales. Contamination by aerosols is a very tangible threat to the cryosphere in the European Alps due to its proximity to highly urbanized areas, cultivated landscapes, and the largest hot desert in the world. We recently developed and assembled a continuous flow analysis system for studying the solid content of ice cores with a high time resolution, focusing on optical characterization methods based on light scattering. The line is designed to provide an integrated measurement of dust particles with Single-Particle Extinction and Scattering (SPES), digital holography, and an optical particle sizer (Abakus). Many of the particles found in ice are efficient scatterers and absorbers close to the size range of the visible light wavelength. We report some preliminary results from ice cores drilled during the ADA270 project, aiming at an in-depth characterization of the samples that provide essential information on the fast climate evolution, which is causing a severe degeneration of glaciers, among other consequences.

Paola Ferri,1 Monica Silvestri,1 Cecilia Artoni,2 Rosaria Di Lorenzo3 1Department of Diagnostic, Clinical and Public Health Medicine, School of Nursing, 2School of Psychiatry, University of Modena and Reggio, 3Department of Mental Health, Service of Psychiatric Diagnosis and Treatment, Modena, Italy Background: Workplace violence (WPV) against health professionals is a global problem with an increasing incidence. The aims of this study were as follows: 1) to examine the frequency and characteristics of WPV in different settings and professionals of a general hospital and 2) to identify the clinical and organizational factors related to this phenomenon. Methods: The study was cross-sectional. In a 1-month period, we administered the “Violent Incident Form” to 745 professionals (physicians, head nurses, nurses, nursing assistants), who worked in 15 wards of a general hospital in northern Italy. Results: With a response rate of 56%, 45% of professionals reported WPV. The most frequently assaulted were nurses (67%), followed by nursing assistants (18%) and physicians (12%). The first two categories were correlated, in a statistically significant way, with the risk of WPV (P=0.005, P=0.004, multiple logistic regression). The violent incidents more frequently occurred in psychiatry department (86%), emergency department (71%), and in geriatric wards (57%). The assailants more frequently were males whereas assaulted professionals more often were females. Men committed physical violence more frequently than women, in a statistically significant way (P=0.034, chi-squared test). Verbal violence (51%) was often committed by people in a lucid and normal state of consciousness; physical violence (49%) was most often perpetrated by assailants affected by dementia, mental retardation, drug and substance abuse, or other psychiatric disorders. The variables positively related to WPV were “calling for help during the attack” and “physical injuries suffered in violent attack” (P=0.02, P=0.03, multiple logistic regression).Conclusion: This study suggests that violence is a significant phenomenon and that all health workers, especially nurses, are at risk of suffering aggressive assaults. WPV presented specific characteristics related to the health care settings, where the aggression occurred. Prevention programs tailored to the different care needs are necessary to promote professional awareness for violence risk.

- Abstract
There is much information to be derived from the airborne dust that can be found in ice cores, especially about the aerosol composition and sources, including the characteristics of the atmosphere of several thousands of years ago. There is, in fact, much still to learn about both the data that can be retrieved and how to interpret them with appropriate models. One of the most striking aspects of these tiny particles is the effect their shape alone has on their scattering and absorption properties, which translate into a contribution to the Earth radiative transfer, especially at the wavelength scale. We show that aggregates of several particles behave differently from compact particles, and non-isometric compact particles can be clearly distinguished from isometric particles as their non-sphericity increases. We report the advances in this direction based on light scattering measurements on the dust content of ice cores drilled from Dome C and Dome B in Antarctica as part of the EPICA project, and provide a physical interpretation in terms of the known models in the field of light scattering by small particles.

- Abstract
We describe an optical approach based on Digital Holography for single-particle characterization of mineral dust and micrometric particles, focusing on the analysis of airborne particles in meltwater from Antarctic ice cores. We record the holograms formed by the superposition of the transilluminating reference beam and the waves scattered by single particles. Taking a cue from recent approaches in the field and holography methods, we process the holograms to recover both optical and morphological properties of single dust grains. As a considerable advantage over traditional light-scattering-based methods, holograms give the extinction cross section of each particle and, by numerically reconstructing the wavefront propagation, an unambiguous image of each particle whereby we derive its cross-sectional shape and size. Measurements have been carried out on samples collected from the recent EAIIST (East Antarctic International Ice Sheet Traverse) project, some of which show evidence of volcanic events. The vast majority of the detected particles show significant deviations from the isometric shape, as confirmed by both image reconstruction and extinction cross section analysis. By our analysis, we observe that experimental data have an extinction cross section up to 3 times lower than that of spherical particles with the same volume. Therefore, these deviations have an appreciable impact on the aerosol contribution to radiative forcing: retrieving particle shape may improve the modeling of the radiative properties of mineral dust and reduce the associated uncertainties.

Ferroelectric random access memory (FeRAM) is an attractive candidate technology for embedded nonvolatile memory, especially in applications where low power and high program speed are important. Market introduction of high-density FeRAM is, however, lagging behind standard complementary metal-oxide semiconductor (CMOS) because of the difficult integration technology. This paper discusses the major integration issues for high-density FeRAM, based on SrBi
2 Ta2 O9 (strontium bismuth tantalate or SBT), in relation to the fabrication of our stacked cell structure. We have worked in the previous years on the development of SBT-FeRAM integration technology, based on a so-called pseudo-three-dimensional (3D) cell, with a capacitor that can be scaled from quasi two-dimensional towards a true three-dimensional capacitor where the sidewalls will importantly contribute to the signal. In the first phase of our integration development, we integrated our FeRAM cell in a 0.35 μm CMOS technology. In a second phase, then, possibility of scaling of our cell is demonstrated in 0.18 μm technology. The excellent electrical and reliability properties of the small integrated ferroelectric capacitors prove the feasibility of the technology, while the verification of the potential 3D effect confirms the basic scaling potential of our concept beyond that of the single-mask capacitor. The paper outlines the different material and technological challenges, and working solutions are demonstrated. While some issues are specific to our own cell, many are applicable to different stacked FeRAM cell concepts, or will become more general concerns when more developments are moving into 3D structures.

calcareous nannofossils ,Triassic/Jurassic boundary ,stable isotopes ,Lombardy Basin - Abstract
In this work, calcareous nannofossils are identified for the first time in the uppermost Triassic sequence of the Lombardy Basin (Southern Calcareous Alps, Italy). Two zones are recognized, namely the NT2b (latest Triassic) and the NJT1 (earliest Jurassic). Two species resulted to be good markers to constrain the TJB interval: Prinsiosphaera triassica and Schizosphaerella punctulata. Nannofossil data are calibrated with C isotopic chemostratigraphy obtained for carbonate and organic matter. Size reduction of P. triassica and a decline in the abundance of Triassic nannofossils are detected soon after the "precursor Carbon Isotope Excursion (CIE) and culminated during the "initial negative CIE" characterized by lowest nannofossil abundances and small-sized P. triassica. The extinction of Triassic nannofossils occurred in distinctive steps within the "initial negative CIE", while the Jurassic S. punctulata is first observed at the base of the "main negative CIE". The latest Triassic nannofossil decline in abundance, size reduction and extinctions, represent a progressive deterioration associated to the Central Atlantic Magmatic Province (CAMP) volcanism. Our findings are consistent with nannofossil changes at supraregional scale and indicate that the massive CAMP flood basalts were preceded by initial volcanic pulses. We speculate that a combination of climate change, fertilization and ocean acidification started to influence the calcification process prior to the "initial negative CIE". Nannoplankton extinctions were not simultaneous and might imply limited capacity for adaptation in the early stages of evolutionary history. However, originations of new taxa soon after the disappearance of Triassic forms suggest the ability to rapidly overcame extreme stressing conditions.

Introduction: According to the WHO, detainees attempt suicide ten times more than the general population. Objectives: To investigate the impact of migration traumas on suicide behaviours of migrants in jail and to explore how substance use and other psychiatric features affect this relation. Methods: Prospective cohort study, conducted at "Sant'Anna" jail in Modena (Italy). Socio-demographic, psychiatric features and previous suicide attempts were collected, and traumas assessed with the LiMEs (List of Migration Experiences) checklist. Every participant was followed-up until an episode of suicide behaviour or to September 2019 (end of study). Survival analysis was performed. Cox's Hazard Ratios were used as a measure of association for the comparison between groups. Results: We recruited 113 subject, 96% male, median age 33. Prevalence of mental disorders was 26% and substance abuse 59%. History of self-harm was present in 36% of the sample. Median follow-up time was 80 days. During follow-up, 11 events were observed (8 self-harm and 3 suicide attempts); cumulative survival probability was 85% (Figure 1). Having experienced traumas related to wars was significantly associated with suicide behaviours, HR: 5.168 (Figure 2, Figure 3). Interestingly, no subject without substance abuse presented the outcome. Conclusions: Migrants in custody who experienced traumas in the post-migration periods, attempt suicide 5 timesmore frequently than those without traumas at any time. War traumas seem to be more strongly associated with suicide attempts, also controlling for psychiatric diagnosis, ongoing psychopharmacological therapy and substance abuse. Further research and possible intervention programs should focus on addressing post-migration living-difficulties. [ABSTRACT FROM AUTHOR]

This paper reports on the integration of MOCVD SBT based stacked ferroelectric capacitors in a 0.35 μm CMOS technology for embedded FeRAM, using a ferroelectric capacitor (FeCap) that is scalable to a 3D configuration. The electrical parameters of the CMOS devices with and without FeCap integration are presented. No significant shifts of the CMOS characteristics are noticed after FeCap integration. Also the effects of the CMOS processing on the FeCaps are discussed. There is no degradation of the hysteresis loops of the FeCaps throughout the CMOS back-end-of-line processing, which proves that the integrated encapsulation layer effectively prevents any hydrogen induced damage. Another key element in the successful integration of stacked ferroelectric devices is the conductive oxygen barrier, which protects the plugs from oxidation. A low contact resistance and a high yield are obtained on plug contacts covered by the oxygen barrier. Also damage free etching is a critical issue in FeRAM integration. Excellent results are presented for the etch process to form the contacts to the electrodes. [ABSTRACT FROM AUTHOR]

In this work, calcareous nannofossils are identified for the first time in the uppermost Triassic sequence of the Lombardy Basin (Southern Calcareous Alps, Italy). Two zones are recognized, namely the NT2b (latest Triassic) and the NJT1 (earliest Jurassic). Two species resulted to be good markers to constrain the TJB interval: Prinsiosphaera triassica and Schizosphaerella punctulata. Nannofossil data are calibrated with C isotopic chemostratigraphy obtained for carbonate and organic matter. Size reduction of P. triassica and a decline in the abundance of Triassic nannofossils are detected soon after the “precursor Carbon Isotope Excursion (CIE) and culminated during the “initial negative CIE” characterized by lowest nannofossil abundances and small-sized P. triassica. The extinction of Triassic nannofossils occurred in distinctive steps within the “initial negative CIE”, while the Jurassic S. punctulata is first observed at the base of the “main negative CIE”. The latest Triassic nannofossil decline in abundance, size reduction and extinctions, represent a progressive deterioration associated to the Central Atlantic Magmatic Province (CAMP) volcanism. Our findings are consistent with nannofossil changes at supraregional scale and indicate that the massive CAMP flood basalts were preceded by initial volcanic pulses. We speculate that a combination of climate change, fertilization and ocean acidification started to influence the calcification process prior to the “initial negative CIE”. Nannoplankton extinctions were not simultaneous and might imply limited capacity for adaptation in the early stages of evolutionary history. However, originations of new taxa soon after the disappearance of Triassic forms suggest the ability to rapidly overcame extreme stressing conditions., Rivista Italiana di Paleontologia e Stratigrafia (Research In Paleontology and Stratigraphy), Vol 122, No 3 (2016)

We describe an optical approach based on Digital Holography for single-particle characterization of mineral dust and micrometric particles, focusing on the analysis of airborne particles in meltwater from Antarctic ice cores. We record the holograms formed by the superposition of the transilluminating reference beam and the waves scattered by single particles. Taking a cue from recent approaches in the field and holography methods, we process the holograms to recover both optical and morphological properties of single dust grains. As a considerable advantage over traditional light-scattering-based methods, holograms give the extinction cross section of each particle and, by numerically reconstructing the wavefront propagation, an unambiguous image of each particle whereby we derive its cross-sectional shape and size. Measurements have been carried out on samples collected from the recent EAIIST (East Antarctic International Ice Sheet Traverse) project, some of which show evidence of volcanic events. The vast majority of the detected particles show significant deviations from the isometric shape, as confirmed by both image reconstruction and extinction cross section analysis. By our analysis, we observe that experimental data have an extinction cross section up to 3 times lower than that of spherical particles with the same volume. Therefore, these deviations have an appreciable impact on the aerosol contribution to radiative forcing: retrieving particle shape may improve the modeling of the radiative properties of mineral dust and reduce the associated uncertainties.

- Abstract
Background: According to the WHO, detainees attempt suicide ten times more than the general population., Aims: To investigate the impact of migration trauma on Suicidal and Self-Harm Behaviours (SSHB) of migrants in jail and to explore how substance use and other psychiatric features affect this relationship., Methods: Prospective cohort study, conducted at the 'Sant'Anna' jail in Modena (Italy) between February 2017 and September 2019. Socio-demographic, psychiatric features and records of previous SSHB were collected. Experience of migration-related trauma was assessed with the LiMEs (List of Migration Experiences) checklist. Participants were followed-up for the occurrence of further SSHB. Survival analysis was performed and Cox's Hazard Ratios (HR) were used as a measure of association of comparisons., Results: Amongst the 112 subjects (96% male, median age 33), the prevalence of any mental disorder was 26% and of substance abuse 59%. History of SSHB was present in 36% of the sample. Median follow-up time was 80 days. During follow-up, 11 events were observed (of which three were suicide attempts). Cumulative survival probability was 85%. Having experienced trauma related to war and violence was significantly associated with SSHB, HR: 7.05. No SSHB were recorded amongst subjects without substance abuse., Conclusions: Migrants in custody who experienced trauma in the post-migration period, attempt SSHB seven times more frequently than those without traumas at any time. War trauma and post-migration trauma due to exposure to violence seem to be more strongly associated with SSHB, also controlling for psychiatric diagnosis, ongoing psychopharmacological therapy and substance abuse. Further research and possible intervention programs should focus on addressing post-migration living-difficulties.

- Abstract
The current treatment of distal femur fractures includes locking plating and retrograde intramedullary nailing. These fractures are difficult to manage also for experienced surgeons, with results not always satisfactory. Reported nonunion rates now range from 0 to 34%. Factors associated with nonunion include comorbidities, such as obesity and diabetes, as well as the presence of open fractures, medial bone defects and comminuted fractures. This case report summarizes all of these assumptions and it concerns a 58 years old patient who underwent to 6 surgical procedures before to arrive to bone healing.

- Abstract
Background and Aim: Pelvic ring fractures represent a challenge for orthopaedic surgeon. Their management depends on patient's condition, pattern of fracture and associated injuries. Optimal timing for synthesis is not yet clear. The aim of this study was to define if surgical timing influenced clinic and radiographic outcomes following open reduction and internal fixation for Tile B and C fractures., Materials and Methods: 38 patients were included. Patients underwent a clinical examination with the Majeed Score, Iowa Pelvic Score and Orlando Pelvic Score. The radiographic assessment was performed according to Matta Pelvic Score. A statistical analysis of the data compared patients who were operated within 3 weeks (group 1) and those operated later (group 2)., Results: Both clinical and radiological outcomes were influenced by timing of surgery., Conclusion: Pelvic ring fractures interest many polytrauma patients and, therefore, their surgical orthopedic approach is frequently delayed as consequence of the severity of the associated clinical conditions. An early surgery of pelvic rong fractures allows a better quality of reduction and osteosynthesis.

- Abstract
Background and Aim: There is a wide debate about the number, diameter and length of the syndesmotic screw and necessity and timing for its removal. The aim of this study is to determine whether functional and radiological outcomes differ in patients operated for Weber type B and C ankle fractures who had syndesmotic screws removed (group 1) compared to those who did not (group 2). Furthermore, authors want to define if it is really necessary to remove this device and its correct timing., Materials and Methods: 90 patients were eligible for the study. The functional outcomes were analyzed 1 year after surgery using OMAS and AOFAS scores. Radiographic evaluation assessed the tibiofibular distance immediately and 12 months after surgery and fracture's healing., Results: Clinical and x-rays results were similar in both groups at follow-up., Discussion: Fractures with interruption of syndesmosis are lesions that, if not well treated, are complicated by joint stiffness, residual pain and post-traumatic osteoarthritis. Syndesmotic screw removal is not routinely performed, thus accepting the risk of rupture but avoiding a new surgery., Conclusions: Results observed suggest that syndesmotic screw removal is not necessary. If surgeon decide to remove this device correct timing is mandatory in order to obtain satisfactory long-term results.

- Abstract
Background: In Italy, psychiatric compulsory treatments are regulated by Law 180 of 13-5-1978 that establishes three criteria: 1) acute psychiatric conditions requiring urgent treatment, 2) patient's refusal of treatment, 3) inpatient treatment is necessary and cannot be postponed., Aim: To highlight demographic and clinical risk factors for involuntary treatments., Methods: We retrospectively collected all hospitalizations in the Service of Psychiatric Diagnosis and Treatment of a northern Italian town from 1-1-2015 to 31-12-2015. We statistically compared demographic and clinical variables related to voluntarily and involuntarily admitted patients and their hospitalizations., Results: We divided our sample into patients voluntarily hospitalized (PVH=236) and involuntarily (PIH=160) according to their voluntary (VH= 304) and involuntary (IH=197) hospitalizations. PIH were older than PVH and, more frequently, lived alone and were unemployed (p<0.001). "Acute worsening of psychopathology" for IH and "Suicidality" for VH were the prevalent reasons (p<0.001). IH was longer than VH (p<0.001). Among PIH, the most frequent diagnoses were "Schizophrenia and Other Psychosis" (ICD-9-CM) and "Ineffective Impulse Control + Disturbed Personal Identity" (NANDA-I) (p<0.001). During hospitalizations, PIH more often than PVH presented aggressive behavior (p<0.001). At discharge, PIH were more frequently sent to another psychiatric ward or protected facility with long-acting injectable antipsychotics (p<0.001)., Conclusions: Our involuntarily admitted patients were affected by severe psychiatric disorders with social maladjustment and required complex therapeutic and rehabilitative programs to counteract aggressive behaviour, poor therapeutic compliance and prolonged hospitalizations. The assessment of patients' characteristics can help clinicians recognize who are at risk for compulsory treatment and prevent it.
