    This paper presents a methodology for assessing and monitoring the cleaning state of a heating, ventilation, and air conditioning (HVAC) system of a building. It consists of a noninvasive method for measuring the amount of dust in the whole ventilation system, that is, the set of filters and air ducts. Specifically, it defines the minimum amount of measurements, their time table, locations, and acquisition conditions. The proposed method promotes early intervention on the system and it guarantees high indoor air quality and proper HVAC working conditions. The effectiveness of the method is proved by some experimental results on different study cases

    The economic impact of moderate stage Alzheimer's disease in Italy: Evidence from the UP-TECH randomized trial

    Background: There is consensus that dementia is the most burdensome disease for modern societies. Few cost-of-illness studies examined the complexity of Alzheimer's disease (AD) burden, considering at the same time health and social care, cash allowances, informal care, and out-of-pocket expenditure by families. Methods: This is a comprehensive cost-of-illness study based on the baseline data from a randomized controlled trial (UP-TECH) enrolling 438 patients with moderate AD and their primary caregiver living in the community. Results: The societal burden of AD, composed of public, patient, and informal care costs, was about �20,000/yr. Out of this, the cost borne by the public sector was �4,534/yr. The main driver of public cost was the national cash-for-care allowance (�2,324/yr), followed by drug prescriptions (�1,402/yr). Out-of-pocket expenditure predominantly concerned the cost of private care workers. The value of informal care peaked at �13,590/yr. Socioeconomic factors do not influence AD public cost, but do affect the level of out-of-pocket expenditure. Conclusion: The burden of AD reflects the structure of Italian welfare. The families predominantly manage AD patients. The public expenditure is mostly for drugs and cash-for-care benefits. From a State perspective in the short term, the advantage of these care arrangements is clear, compared to the cost of residential care. However, if caregivers are not adequately supported, savings may be soon offset by higher risk of caregiver morbidity and mortality produced by high burden and stress.

    Socioeconomic Predictors of the Employment of Migrant Care Workers by Italian Families Assisting Older Alzheimer's Disease Patients: Evidence from the Up-Tech Study

    Get PDF
    Background: The availability of family caregivers of older people is decreasing in Italy as the number of migrant care workers (MCWs) hired by families increases. There is little evidence on the influence of socioeconomic factors in the employment of MCWs. Method: We analyzed baseline data from 438 older people with moderate Alzheimer's disease (AD), and their family caregivers enrolled in the Up-Tech trial. We used bivariate analysis and multilevel regressions to investigate the association between independent variables - education, social class, and the availability of a care allowance - and three outcomes - employment of a MCW, hours of care provided by the primary family caregiver, and by the family network (primary and other family caregivers). Results: The availability of a care allowance and the educational level were independently associated with employing MCWs. A significant interaction between education and care allowance was found, suggesting that more educated families are more likely to spend the care allowance to hire a MCW. Discussion: Socioeconomic inequalities negatively influenced access both to private care and to care allowance, leading disadvantaged families to directly provide more assistance to AD patients. Care allowance entitlement needs to be reformed in Italy and in countries with similar long-term care and migration systems. � 2015 The Author 2015.

    The present description relates to a method for preparing a biocide enriched in oxygen-centred free radicals through UV radiation, a biocide enriched in oxygen- centred free radicals thus obtained, a method for sterilizing waters, a method for controlling the colonisation of micro-organisms in treated waters, as well as a method for controlling and/or for controlling and preventing the colonisation on the surfaces of submerged structures by aquatic filtering organisms that use said biocide enriched in oxygen-centred free radicals and plants suitable for implementing said methods

    The Effect of Morphometry, Land-Use and Lithology on Landslides Susceptibility: An Exploratory Analysis

    No full text
    GIS features provide simple and useful tools for landslides susceptibility and hazard studies, allowing the identification and the quantification of predisposing factors, and their relative importance. In lithologically homogeneous areas, the most influent factor of landslides is slope morphometry, in particular inclination, height and form. Moreover, within a hydrographic basin, landslides are coupled with drainage network. In fact landslides density and drainage density are positively correlated. Furthermore, human activity strongly influences the development of landslides. In our previous works, we introduced MSI (Morphometric Slope Index) as general index for slope morphometry, combining the main linear and areal morphometric features (area, form, length, inclination, width). Its formula is: MSI=A3D/A2D·L·Rc (where A3D is the three-dimensional area of the slope, A2D is its plan area, L is the slope length and Rc is the circularity ratio). We tested MSI as driver of different erosion landforms, demonstrating its influence in determining, on the one hand, the development and the final arrangement of calanchi drainage network (the typical Italian badlands), and, on the other hand, the erosion processes within them, mainly gullies and landslides. The present study is an exploratory application of this index to landslides susceptibility, aimed to analyze the combined effect of slope morphometry (summarized in MSI), lithology and land-use on the distribution of landslides in small catchments. The study is located in the Italian periadriatic foredeep, in the Abruzzo Region. This study has reinforced our perspective about the validity of the application of the techniques of geomorphometric analysis to the landslides susceptibility. Especially we consider this approach an efficient tool to summarize different controlling factors

    Late quaternary geomorphological evolution and erosion rates in the clayey peri-Adriatic belt (central Italy).

    This study analyses the geomorphological evolution during the last 20000 years in two areas representative of the peri-Adriatic belt of central Italy: Mt. Ascensione in the high hilly sector (600–1100 m a.s.l.) and the Atri district in the hilly-coastal sector (up to ca. 500 m a.s.l.). In both areas the lithostructural setting is characterized by an east-verging monocline mainly composed of clayey formations. The two areas are compared in relation to their morpho chronological aspects and geomorphological dynamics. The results suggest two fundamental evolutionary phases: 1) About 20000 yr BP sedimentation occurred along the main valleys when the middle to upper portions of slopes were covered by colluvial deposits; and 2) At the beginning of the Holocene, the climatic improvement triggered erosion along rivers, producing deep and narrow valleys. Estimated denudation rates during the last 20000 yr are 7.8 mm yr−1 for the Mt. Ascensione area and 2.4–3.0 mm yr−1 for the Atri district, reflecting frequent landslides and fluvial erosion. The rates are consistent with the data available in literature. Denudation rates double if we assume most of the erosion process took place after the beginning of the Holocenic warming phase
