Analysis of Protected Accidental Transients in the EFIT Reactor With the RELAP5 Thermal-Hydraulic Code

2008

The European Facility for Industrial Transmutation (EFIT) is aimed at demonstrating the feasibility of transmutation process through the Accelerator Driven System (ADS) route on an industrial scale. The conceptual design of this reactor of about 400 MW thermal power is under development in the frame of the European EUROTRANS Integrated Project of the EURATOM Sixth Framework Program (FP6). EFIT is a pool-type reactor cooled by forced circulation of lead in the primary system where the heat is removed by steam generators installed inside the reactor vessel. The reactor power is sustained by a spallation neutron source supplied by a proton beam impinging on a lead target at the core centre. A …

Uso de medicamentos associados ao risco de quedas em idosos não institucionalizados

2018

RESUMEN Objetivo: Determinar qué número de medicamentos consumidos diariamente es influyente en el riesgo de caídas en ancianos no institucionalizados y con historial de caídas en el último año. Método: Estudio descriptivo mediante muestreo aleatorio con la utilización de los siguientes instrumentos de medida: cuestionario de la OMS para el estudio de caídas en el anciano, escala de marcha y escala depresión geriátrica y escala de marcha y equilibrio. El análisis univariante, bivariante con prueba no paramétrica de Chi-cuadrado y regresión logística binaria se ellevó a cabo con el programa estadístico SPSS versión 21.0. Resultados: Participaron del estudio 213 personas. El consumo ≥ a 4 med…

Transient response of a TLP-type floating offshore wind turbine under tendon failure conditions

2021

Abstract Among various types of floating offshore wind turbines (FOWTs), the tension leg platform (TLP) floating wind turbines have relatively small motions due to stiff tendons. Similar to TLP applications in the offshore industry, tendon failure may lead to deteriorated stability and large transient responses, which should be considered as part of accidental limit state (ALS) checks at the design stage of the TLP FOWTs. This paper takes the WindStar TLP system as a representative and investigates the transient effects of one-tendon failure on the system responses. A coupled numerical model is first established using the aero-hydro-servo-elastic simulation tool FAST. Subsequent numerical s…

FIRST RECORD IN ITALY OF PSYLLAEPHAGUS BLITEUS RIEK (Hymenoptera Encyrtidae) PARASITOID OF GLYCASPIS BRIMBLECOMBEI MOORE (Hemiptera Psyllidae)

2011

Psyllaephagus bliteus Riek (Hymenoptera Encyrtidae), parasitoid of the red gum lerp psyllid Glycaspis brimblecombei Moore (Hemiptera Psyllidae), has been recorded for the first time in Italy in September 2011. The arrival of P. bliteus in Sicily is due to an accidental introduction, probably together with its host, as already happened in New Zealand, Brazil, Spain and Morocco.

Virtual simulation of an osseointegrated trans-humeral prosthesis: A falling scenario

2018

Abstract Introduction Traditional prosthetic solutions expose the amputee to numerous problems that limit his ability to safely perform the normal activities of daily life. In order to eliminate the problems related to the use of the traditional prosthesis with socket, a new technique was developed for fixing the prosthesis to the amputees based on the principle of osseointegration. The aim of this paper is to study and analyze the stress distribution on the interface between a trans-humeral osseointegrated prosthetic implant and the residual bone, identifying the most stressed areas and thus foreseeing possible failure phenomena of the entire prosthetic system and, after, to compare the st…

Factors associated with fear of falling among frail older adults

2021

Some factors increase the fear of falling in frail older adults. Our aim is to quantify the influence of these factors. This cross-sectional study involved 229 community-dwelling prefrail and frail older adults aged 70 years and older. Fear of falling was moderate in 38.9% of our sample and high in 12.2%. Higher values were observed in women, those living alone, and those meeting criteria for slowness and feelings of exhaustion. A linear regression showed that being a woman, a history of falls, and depressive symptoms were related to higher fear of falling, while high levels of independence in basic and instrumental activities of daily living, along with good gait and balance, were associat…

A comprehensive fracture prevention strategy in older adults : The European union geriatric medicine society (EUGMS) statement

2016

Published also in Aging Clinical and Experimental Research, Vol.28, No.4, WOS: 000379034800030 Prevention of fragility fractures in older people has become a public health priority, although the most appropriate and cost-effective strategy remains unclear. In the present statement, the Interest group on falls and fracture prevention of the European union geriatric medicine society (EUGMS), in collaboration with the International association of gerontology and geriatrics for the European region (IAGG-ER), the European union of medical specialists (EUMS), the Fragility fracture network (FFN), the International osteoporosis foundation (IOF) - European society for clinical and economic aspects …

Clinical features of prefrail older individuals and emerging peripheral biomarkers: A systematic review

2013

Frailty is a geriatric syndrome characterized by the clinical presentation of identifiable physical alterations such as loss of muscle mass and strength, energy and exercise tolerance, and decreased physiological reserve. Individuals with one or two of these alterations are defined as prefrail. The clinical features of prefrail older individuals have been investigated to a lesser extent compared to the frail population, even though this intermediate stage may provide insights into the mechanisms involved in the physical decline associated with aging and it is considered to be potentially reversible. We performed searches in the Medline, Embase, Scopus, Cinahl, and Cochrane databases from Ja…

Fall incidence in frail older women after individualized visual feedback-based balance training.

2003

<i>Background:</i> The knowledge concerning balance training actually lowering fall rates among frail older persons is limited. <i>Objective:</i> The aim of this study was to examine the effects of a 4-week individualized visual feedback-based balance training on the fall incidence during 1-year follow-up among frail older women living in residential care. <i>Methods:</i> Twenty-seven older women from 2 residential care homes were randomized into exercise (n = 20) and control (n = 7) groups. Balance measurements were carried out before and after a 4-week training period and falls were monitored by monthly diaries for 1 year. An interview about fear of fal…
