An Interdisciplinary Approach to the Significance of Digital Economy for Competitiveness in Romanian Rural Area Through E-agriculture

2014

Abstract The digital economy is the key factor in the recovery of the EU economy and especially the Romanian economy. Based on its strengths in technology and knowledge, Europe should exploit the full potential of the digital economy. The digital economy offers great opportunities for SMEs in the manufacturing and service sectors. Therefore, an ambitious Digital Agenda, providing concrete steps to complete the online single market will be a key to sustainable economic recovery and social development of Europe. The understanding of what makes them a success or failure, and how much impact they may have in contributing to the wider rural economy is still relatively poorly developed. What is c…

Linear ViscoElastic (LVE) Behaviour of Pure Bitumen via Fractional Model

2012

AbstractBy fitting experimental data from static creep/recovery carried out on pure bitumen, it is shown that the fractional model proposed enables the description of both creep and recovery behaviour with fewer parameters than those needed by other models in the literature. In particular, the model is fitted to experimental data of complex modulus |G*| and phase angle δ° obtained from Dynamic Mechanical Analysis. Lastly, it is demonstrated that when the fractional model is used, complex modulus isotherms for a range of frequencies can be created simply starting from isochronals at f = 1Hz.

Managing Municipal Solid Waste: Energetic and Environmetal Comparison among different options

2001

Goal. This research aims to assess the environmental effects of integrated strategies in a municipal waste management system. In particular, analysis is focused on a waste stream in Palermo, where landfill involves the prompt disposal of the most waste after collection. The current local management system is compared with two integrated waste management alternatives. Both the options comply with Italian regulations, but each one predicts adopting the available technologies in different ways. Methods and objectives. Energetic and environmental balances are carried out in each management system referring to local waste composition in order to quantify energy consumption, the recovery of mater…

Public procurement: current situation and points of improvement

2015

[ES] La construcción pública ha sido, es y será uno de los pilares fundamentales del sector construcción español, si bien la actual situación de crisis económica y la reducción de la inversión pública en nuevas infraestructuras ha generado un descenso de actividad hasta niveles similares a los años noventa. El retorno a índices de actividad más elevados no solo se conseguirá con la recuperación de la economía del país, sino que será necesario realizar ciertas mejoras en los procesos de licitación con objeto de conseguir una mayor funcionalidad y flexibilidad en la contratación pública de obras.

Sull’attuazione degli obblighi internazionali di risposta e ripresa a fronte della pandemia di Covid-19: una prospettiva italiana

2023

This work aims at offering a critical analysis of how Italy, as one of the most early-affected countries, has responded to and is currently recovering from the Covid-19 pandemic, in the framework of international and European obligations applicable to CBRN events at large. To this end, this article will first examine the main obligations concerning «response» to and «recovery» from a pandemic event, as stemming from relevant international and European law instruments. Then, it will look at how these obligations have been implemented by Italian central and local authorities vis-à-vis the Covid-19 pandemic, while also offering some conclusive remarks on the legal meaning of the «disaster mana…

Low-Head Hydropower for Energy Recovery in Wastewater Systems

2022

Hydraulic turbines for energy recovery in wastewater treatment plants, with relatively large discharges values and small head jumps, are usually screw Archimedes or Kaplan types. In the specific case of a small head jump (about 3 m) underlying a rectangular weir in the major Palermo (Italy) water treatment plant, a traditional Kaplan solution is compared with two other new proposals: a Hydrostatic Pressure Machine (HPM) located at the upstream channel and a cross-flow turbine (CFT) located in a specific underground room downstream of the same channel. The fluid mechanical formulations of the flow through these turbines are analyzed and the characteristic parameters are stated. Numerical ana…

Development and Preliminary Italian Validation of the Emergency Response and Psychological Adjustment Scale

2021

Evaluating the personal adaptation response to the emergency situations is very important for the prevention of mental distress, for the activation of network and community synergies and for the planning and implementation of appropriate psycho-social interventions. So far there are no short tools for the overall assessment of cognitive, emotional and behavioral responses of psychological adaptation to the emergency in the psychometric panorama. The Emergency Response and Psychological Adjustment Scale (ERPAS) was administered to a sample of 1,088 participants, while the concurrent validity was tested through a second administration to 600 participants along with the GSE (Generalized Self-E…

Recovery of aliphatic low-molecular-mass carboxylic acids from hardwood kraft black liquor

2015

Abstract During alkaline pulping of wood, substantial amounts of carbohydrates-derived aliphatic carboxylic acids (formic and acetic acids together with various hydroxy acids) are formed and dissolved into the cooking liquor (“black liquor”). These acids with low heating values are considered to be potential feedstocks for the chemical industry but, due to many factors, their straightforward recovery as free acids from black liquor (pH 13–14) is difficult. In this paper, we outlined the partial recovery of volatile formic and acetic acids from the acidified birch ( Betula pendula ) kraft black liquor (pH approximately 2.5) by distillation, and the partial recovery of significant low-molecul…
