EVAPOTRANSPIRATION, CROP COEFFICIENTS AND WATER USE EFFICIENCY OF CYPERUS ALTERNIFOLIUS L. AND TYPHA LATIFOLIA L. IN A PILOT-SCALE HORIZONTAL SUBSURF…

2014

In constructed wetland systems (CWs) for wastewater treatment, the efficiency of the system is highly affected by the system’s water balance. This study shows the results of a series of water balance measurements obtained in 2013 from a pilot horizontal-subsurface flow (HSSF) system in the West of Sicily (Italy). The system included three separate units, one planted with Cyperus alternifolius L., one planted with Typha latifolia L. and an unplanted unit. The system was fed with urban wastewater from an activated-sludge wastewater treatment plant. The aim of the study was to compare evapotranspiration rates (ET), crop coefficients (Kc) and water use efficiency (WUE) of two root emergent macr…

Videowikis for improved problem-based collaborative learning: Engaging information systems science students

2013

The contemporary era of social media and web 2.0 has enabled a bottom-up on-line collaborative approach with easy content creation and subsequent knowledge sharing. The technically literate students of today and the changes in pedagogy towards a user-centred approach, where learners engage in the learning process by constructing new ideas and concepts based on their current or past knowledge facilitate the use of social media in learning environments. This paper describes the combination of a wiki and screen capture videos as a complementary addition to conventional lectures in an information management and information systems development course. The basis for our approach was collaborative…

Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor

2010

Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …

Upside-down ship’s kel-shaped vaults as a contemporary design criteria. The case of the Palace of the Dukes of Braganza in Guimarães (Portugal)

2015

A contemporary worldwide trend is exposing the structural elements of a building to create an articulate and complex architecture whose lines of force give robustness, stability and, at the same time, a sort of lightness and frivolity to the entire construction. However, the combination between the visual conception of architecture and the principles of statics is not new to the world of construction. Exposed structure as a design approach may be observed in many historical buildings, either public, religious or private, and in several cultural and geographical areas where exposed structures communicate power, solidity, and rigour along with an instance of economy and lightness. In this wor…

Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…

2014

The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…

The Relationship between Knowledge Characteristics’ Fit and Job Satisfaction and Job Performance: The Mediating Role of Work Engagement

Inspiriting Innovation: The Effects of Leader-Member Exchange (LMX) on Innovative Behavior as Mediated by Mindfulness and Work Engagement

2021

Continuous innovation has become a key to gaining a sustainable competitive advantage for organizations in the 21st century. By focusing on the underlying mechanisms (i.e., mindfulness and work engagement) by which it works, this study addresses the quality of leader–member relationships and their relevance for innovation in the workplace. Using a sample of 210 employees from 17 Spanish companies, a two-wave longitudinal design evaluated the mediational roles of mindfulness and engagement between leader–member exchange (LMX) quality and innovative work behavior (IWB) in an organizational context. Over the course of a year, two questionnaires were administered to measure LMX quality, mindful…

Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light

2017

Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
