Geophysical and geotechnical investigations to support the restoration project of the Roman ‘Villa del Casale’, Piazza Armerina, Sicily, Italy
2011
A multidisciplinary geophysical and geotechnical study, including some non-invasive geophysical applications, was carried out during the restoration of the ‘Villa del Casale’, a Roman villa discovered near Piazza Armerina (Sicily, Italy) in 1929, famous for its Roman floor mosaics. The project aims were to characterize the geology of the subsoil and provide information for solving the main building structural problems including the subsidence of some parts of the floor and the detachment of the tesserae (i.e., the tiles) of the mosaics. Another goal was the detailed study of the underground structures of the Corridor of the Great Hunt, a part of the villa strongly affected by subsidence and…
Psychological resilience and active aging among older people with mobility limitations.
2020
Active aging refers to striving for well-being through preferred activity and may be restricted with declining mobility. We investigated whether psychological resilience, i.e., the ability to tolerate hardship, can aid older people in being active despite mobility limitations. Participants were 961 community-dwelling persons aged 75, 80, or 85 years living in Jyväskylä, Central Finland. Mobility limitations were indicated as self-reported difficulty in walking 2 km. Categories were no difficulty (reference), difficulty, and unable to walk. Resilience was assessed with the 10-item Connor–Davidson Resilience Scale and active aging with the University of Jyvaskyla Active Aging scale. Data were…
Dual sensory loss and social participation in older Europeans
2013
The purpose of the study was to describe the prevalence of hearing difficulties, vision difficulties and dual sensory difficulties in 11 European countries, and to study whether sensory difficulties are associated with social inactivity in older Europeans. This cross-sectional study is based on the 2004 data collection of the Survey of Health, Ageing and Retirement in Europe comprising 27,536 men and women aged 50 years and older. Hearing and vision difficulties, as well as participation in seven different social activities were assessed using a structured computer-assisted personal interview. Logistic regression models were used for analyses. Altogether, 5.9 % of the participants reported …
Self-rated resilience and mobility limitations as predictors of change in active aging during COVID-19 restrictions in Finland : a longitudinal study
2021
AbstractSocial distancing during the COVID-19 pandemic decreased older people’s opportunities to lead an active life. The purpose of this study was to investigate whether walking difficulties predict changes in leading an active life during the COVID-19 social distancing recommendation compared to 2 years before, and whether self-rated resilience moderates this association among older people. Data were collected during social distancing recommendation in May and June 2020 and 2 years before (2017–18) among community-living AGNES study participants initially aged 75, 80, or 85 years (n = 809). Leading an active life was assessed with the University of Jyväskylä Active Aging Scale (UJACAS; to…
Models of long-term care use among older people with disabilities in Taiwan: institutional care, community care, live-in migrant care and family care
2014
The four main models of long-term care (LTC) for older people in Taiwan are institutional care, community & home-based care, live-in migrant care, and family care. This study aims to examine the factors associated with the four above-mentioned LTC models, using the Andersen model as its framework for analysis. Data were from the 2005 National Taiwanese Health Interview Survey (n=30,680) and in this study 592 over-65-year-old persons who require personal care in daily life were included. The findings showed that the majority of older people with care needs lived with family and were cared only by their family. The second largest group were those older people who were cared by migrant care wo…
Global distributions of diazotrophs abundance and biomass - Depth integrated values computed from a collection of source datasets - Contribution to t…
2013
The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedente…
Application of non-invasive seismic techniques for the characterisation of a gravity concrete dam
2020
The use of non-invasive investigation methods is becoming frequent as a support for the monitoring of water reservoirs and for the management of dam safety. In this context, geophysical techniques are much less invasive than geotechnical tests and allow to obtain two-dimensional or three-dimensional representations of the mechanical parameters of an engineering structure. A case of application of constrained inversion and joint interpretations of non-invasive seismic techniques is discussed, in order to monitor the Dirillo gravity concrete dam, in Sicily. To investigate the foundation soil, a stratigraphic borehole and a vertical seismic profile, carried out in the same hole, were used to c…
Klinisches Neugeborenenscreening zur Erfassung angeborener Fehlbildungen
2001
Epidemiologische Daten eines klinischen Neugeborenenscreenings sind die Grundlage, zeitliche und regionale Trends von Fehlbildungspravalenzen zu erfassen, Risikofaktoren und damit Ansatzpunkte fur Praventionsmasnahmen zu ermitteln, Praventionsmasnahmen zu veranlassen bzw. zu uberprufen sowie Forschungsprojekte zu initiieren. Zur Erfassung valider Daten und zur Vermeidung von Beobachter-, Definitions- und Selektionsverzerrungen sollten aktive Erfassungssysteme verwendet werden. 34.211 Lebendgeborene, Totgeborene und Aborte der populationsbezogenen Geburtenkohorte des aktiven Mainzer Geburtenregisters wurden nach einem standardisierten Schema klinisch und sonographisch untersucht und anamnest…
Regression of advanced rat and human gliomas by local or systemic treatment with oncolytic parvovirus H-1 in rat models
2010
Oncolytic virotherapy is a potential treatment modality under investigation for various malignancies including malignant brain tumors. Unlike some other natural or modified viruses that show oncolytic activity against cerebral neoplasms, the rodent parvovirus H-1 (H-1PV) is completely apathogenic in humans. H-1PV efficiently kills a number of tumor cells without harm to corresponding normal ones. In this study, the concept of H-1PV-based virotherapy of glioma was tested for rat (RG-2 cell-derived) and for human (U87 cell-derived) gliomas in immunocompetent and immunodeficient rat models, respectively. Large orthotopic rat and human glioma cell-derived tumors were treated with either single …
