Detailed and accurate geomorphological historical landslide inventory maps
are an invaluable source of information for many research topics and
applications. Their systematic preparation worldwide ...has been advised by
many researchers as it may foster our knowledge on landslides, their spatial
and temporal distribution, their potential interaction with the built
environment, their contribution to landscape dynamics, and their response to climate change in the past. Due to the extreme variability of the
morphological and radiometric elements that can reveal historical
landslides, geomorphological historical landslide inventory maps are
produced by expert interpretation, which makes it a time-consuming and expensive process, which often discourages wide-area mapping activities. In this paper we present a new geomorphological historical landslide inventory
map for a 1460 km2 area in the Daunia Apennines, the north-western sector of the Apulia (Puglia) region, in southern Italy. The inventory
contains 17 437 landslides classified according to relative age, type of
movement, and estimated depth. Landslides were mapped according to rigorous and reproducible criteria applied by two teams of expert photo interpreters to two sets of stereoscopic aerial photographs taken in 1954/55 and 2003.

A precision measurement of the ratio RK of the rates of kaon leptonic decays K±→e±ν and K±→μ±ν with the full data sample collected by the NA62 experiment at CERN in 2007–2008 is reported. The result, ...obtained by analysing ∼150000 reconstructed K±→e±ν candidates with 11% background contamination, is RK=(2.488±0.010)×10−5, in agreement with the Standard Model expectation.
Abstract
Introduction
WHO stresses the need to implement multi-component interventions to raise coverage among healthcare workers (HCWs). We investigated different HCWs influenza immunization ...programs within Friuli Venezia Giulia (FVG) Region hospitals (Italy) during 2019-20 flu season with the aim of identifying the most effective strategies to tackle hesitancy.
Methods
In December 2019 we collected from FVG hospitals: number of employed HCWs, vaccination strategies against flu and refusers management during 2019-20 flu season. We obtained data about HCWs flu vaccination coverage from the regional database; Chi-square test was used to find correlation between strategies and coverage.
Results
We collected data from 7/7 hospitals for a total of employed HCWs of 12,557 (average 1,794; range 467-3,922); 2 hospitals being academic centers and 2 research institutions. All hospitals promoted flu vaccination using emails, notice on hospital website and posters display; 3/7 organized training courses. Vaccination was always provided within the hospital in a dedicated easy and free access room; most hospitals (5/7) also offered ward on-site sessions, some allowing ward self-administration (3/7) or organizing on demand extra-sessions (2/7). No countermeasures were taken in case of refusal. Regional HCWs flu vaccination coverage resulted to be 24.9% (range 17-33.3). Multi-component intervention including passive and active offer, communication and education activities was confirmed to be significantly associated with higher HCWs flu coverage (OR 1.7; CI 1.6-1.9; p < 0.01), as well as being the hospital an academic center or a research institution (OR 1.3; CI 1.2-1.5; p < 0.01).
Conclusions
Different strategies to foster HCWs vaccination were adopted in FVG Region during 2019-20 flu season. The multi-component approach producing the best results should be further analyzed in order to identify the most effective recipe to be shared both nationally and internationally.
Key messages
Investigating the relation between HCWs flu immunization strategies and their effect is crucial to identify best practices. A multi-component approach including passive and active offer, communication and education activities seems the most effective way to tackle influenza vaccine hesitancy among HCWs.
Lithological maps contain information about the different
lithotypes cropping out in an area. At variance with geological maps,
portraying geological formations, lithological maps may differ as a ...function of their purpose. Here, we describe the preparation of a lithological map of
Italy at the 1:100 000 scale, obtained from classification of a
comprehensive digital database and aimed at describing geomechanical properties. We first obtained the full database, containing about 300 000
georeferenced polygons, from the Italian Geological Survey. We grouped polygons according to a lithological classification by expert analysis of the 5456 original unique descriptions of polygons, following compositional and geomechanical criteria. The procedure resulted in a lithological map with a legend including 19 classes, and it is linked to a database allowing
ready interpretation of the classes in geomechanical properties and is amenable to further improvement. The map is mainly intended for statistical
and physically based modelling of slope stability assessment and geomorphological and geohydrological modelling. Other possible applications include geoenvironmental studies, evaluation of river chemical
composition, and estimation of raw material resources. The dataset is publicly available at https://doi.org/10.1594/PANGAEA.935673

Objectives: The aim of the study was to examine, in a sample of Italian women, the rate of discontinuation of use of hormonal contraception.
Methods: In a retrospective cross-sectional study, data ...were collected from a chart review of 1809 women using or stopping the hormonal contraceptive prescribed by their physician. The name of the contraceptive and the reason for discontinuation were taken from the charts. The differences between the methods regarding reasons for discontinuation were analysed.
Results: Of the 1809 women examined, 34.9% had discontinued their hormonal contraception: 6.9% did so for non-method-related reasons, 20.5% due to minor side effects, 4.4% due to major side effects and 3.8% due to difficulties with compliance. Irregular bleeding, weight gain and headache were the main reasons reported for discontinuation. Pills containing 30 μg or 20 μg ethinylestradiol (EE) and the vaginal ring were the most used contraceptive methods. Women using the vaginal ring discontinued less frequently compared with pill users (p < .005). Pills containing 20 μg and 30 μg EE had the same discontinuation rate. Venous thrombosis was the most frequently reported major side effect leading to discontinuation.
Conclusion: About one-third of women who used modern hormonal contraceptives discontinued the method. Although the percentage of women who gave up as a result of minor side effects was lower than it used to be, and the use of low doses of EE by the vaginal route has decreased the rate of discontinuation, physicians should counsel women about the possibility of side effects and encourage them to seek advice before stopping.

A procedure is described by which nonlinear finite-element algorithms can be modified to enable the analysis of repaired or rehabilitated concrete structures, taking into account the chronology of ...the loading, damage, and repair. The method defines and employs plastic strain offsets in the context of a smeared rotating crack model. The ability to engage and disengage elements at various stages of loading, as well as the ability to carry forward strain measures representing previous loading and damage conditions, are key aspects in the analysis method. Analysis of beams and slabs repaired with fiber-reinforced plastics demonstrates the accuracy of the procedure in accounting for changes in strength, stiffness, ductility, and failure mode as a result of strengthening measures. Flexure-dominated and shear-dominated responses are equally well represented. The analysis of a repaired shear wall, subjected to reversed cyclic loads, illustrates the ability to model severely damaged structures where some portions must be removed and reconstructed. In all cases, the analysis procedure was numerically stable and efficient at all stages of loading.

The NA62 RICH detector Anzivino, G.; Bucci, F.; Carassiti, V. ...
2013 IEEE Nuclear Science Symposium and Medical Imaging Conference (2013 NSS/MIC),
10/2013
Conference Proceeding
The main goal of the NA62 experiment is the measurement of the K + → π + νν̅ branching ratio with a precision better than 10%. One of the key element of NA62 is the Ring Imaging CHerenkov detector ...(RICH). It will identify pions and muons in the momentum range between 15 and 35 GeV/c, with a muon rejection factor better than 10 -2 . The RICH will also measure the particle arrival time with a precision better than 100 ps to disentangle accidental time associations of beam particles with pions and will provide the reference time and a fast signal for the NA62 trigger system. We present the final design of the detector and the status of the construction. Finally, we recall the results of the beam tests of the RICH prototype.
Abstract
Issue
Influenza vaccination of Healthcare workers (HCW) has a key role in avoiding flu transmission among patients and HCWs and is annually recommended by health authorities. Despite the 75% ...target identified by WHO, coverage is still inadequate in many European countries.
Description of the problem
The Infection Control Team and Public Health Residents of a University Hospital annually cooperate to actively offer flu shots directly in the Units, but in 2017-18 campaign only 12,1% of HCWs took advantage of the service. From July to December 2018 a composite intervention was performed to increase immunization rates. In each Unit a medical doctor and a nurse (midwife for the Obstetrics unit) were identified as Link Professionals (LPs).Two educational meetings with Infectious Diseases and Public Health experts were organized for LPs to deal with their hesitancies and to engage them for the vaccination promotion among colleagues.The calendar (2/week ambulatory + 16 in-ward appointments), tailored to maximise the HCW accessibility, was sent to medical consultants and head of departments, to all physicians, and to head nurses for dissemination. Promotional posters and videos were displayed across the hospital.
Results
Educational meetings were attended by 130 LPs. A total of 772/3420 HCW took advantage of the 2018-19 active campaign (22,6%), with a significant increase from the previous year (+10,4%; 95%CI 8,7-12,2; p < 0,001). The immunization rates raised in all HCWs categories: 279/660 doctors (it was 167/660 in 2017-18; +17.0%; 95%CI 11,9-21.9; p < 0,001); 303/1615 nurses (150/1615 in 2017-18; +9.5%; 95%CI 7.1-11-9; p < 0,001); 13/43 midwives (2/43 in 2017-18; +25,6%; 95%CI 9.7-40.8; p = 0,002).
Lessons
Despite the significant increase,further efforts are necessary to reach the WHO target rate. All HCWs categories were positively affected by the multi-modal intervention. LPs seem to play an important role in promoting vaccination among colleagues, in a peer-to-peer trust relationship.
Key messages
Influenza vaccination rates needs to be increased in healthcare workers for their protection and for patient safety.
A well-structured multi-modal intervention programme involving prepared HCW promoters into wards is essential to increase compliance.
