Experimental evaluation of plasters durability aimed at maintenance planning and scheduling

2011

The phase of building management has a strategic importance because of the necessary scheduling of maintenance during executive planning. Moreover, in order to obtain the greatest sustainability of the intervention, a reasonable duration of service life must be balanced with global quality-cost ratio. A contribution towards this objective is given by the reduction in the achievable resources and raw materials consumption through the improvement of the durability requirement of building and its parts. This is true even for the interventions on the existing public building stock, especially if there is lacking of maintenance planning and scheduling. This work, taking cues from a maintenance i…

Il colore delle idee

2018

The myth of white in architecture has ancient roots partially sprouting from a classic ideal revived by modernism that now seems to acquire new values. Also in light of its current global dissemination – from the US to Europe and Japan – white architecture cannot be considered as a fad, nor can it be reduced to a mere Mediterranean character. Fran Silvestre Arquitectos’ production exemplifies the complexity of this phenomenon with its presence in the contemporary international scene and a range of works, mostly housing designs, of remarkable quality. The trajectory illustrated in this book partially results from the re-reading of the modern as well as Mediterranean architectural tradition, …

Indoor lighting quality: Effects of different wall colours

2016

This paper reports the results of measurements performed in a test room to investigate the impact of using different wall colours and light scenes on indoor lighting quality. Eye level spectral irradiances were measured for a user located inside the room and seated at a desk. These measurements allow the use of the Irradiance Toolbox, which makes it possible to calculate equivalent illuminances for the photopigments in the human eye. Moreover, the CIECAM02 colour appearance model was used to investigate the variations in hue and chroma values of the different wall colours when changing the light scene. The results demonstrate that there are significant variations in eye level spectral irra…

Analisys on the feasibility to modulate lighting systems load: the case study of Palermo

2022

The feasibility to shift and/or modulating the loads that characterize buildings can be useful to improve the performance of smart grids. As known, it is not possible to shift in the time the operating time of the lighting system, but it is possible to modulate the needed electric power. In this paper, the first set of data and a preliminary analysis conducted in the Solarlab of the University of Palermo are presented. The innovative lighting system was designed, sized and installed with the aim of evaluating the consumption of an island user that can be controlled by the DSO or an aggregator. In order to do this, the lighting system load was modulated by applying different strategies: vary…

Missense and nonsense mutations in melanocortin 1 receptor (MC1R) gene of different goat breeds: association with red and black coat colour phenotype…

2009

Abstract Background Agouti and Extension loci control the relative amount of eumelanin and pheomelanin production in melanocytes that, in turn, affects pigmentation of skin and hair. The Extension locus encodes the melanocortin 1 receptor (MC1R) whose permanent activation, caused by functional mutations, results in black coat colour, whereas other inactivating mutations cause red coat colour in different mammals. Results The whole coding region of the MC1R gene was sequenced in goats of six different breeds showing different coat colours (Girgentana, white cream with usually small red spots in the face; Maltese, white with black cheeks and ears; Derivata di Siria, solid red; Murciano-Granad…

Relationship between socioeconomic factors and intelligence of preschoolers: A cohort study in the Serbian context

2020

The aim of the current research is to analyse the relationship between the socioeconomic status (SES) of parents and intellectual abilities (IQ) of preschool children of Serbian territory, and in particular how SES factors relate to preschool children’s IQ measured with Raven’s Coloured Progressive Matrices (CPM), in the different age groups. The research included 430 parents and 430 preschool children. A confirmatory factor analysis of the SES questionnaire revealed five factors: educational and professional status of father and mother, residential and educational status of the family, sport status of parents and comfort of family housing. No gender differences in IQ levels were found in c…

Seven Shades of Grey: A Follow-Up Study on the Molecular Basis of Coat Colour in Indicine Grey Cattle Using Genome-Wide SNP Data

2022

Shades of grey and brown are a dominant component in mammal coat colours, representing a fundamental trait involved in a great number of processes including cryptism, sexual selection and signalling. The genetic mechanisms of the grey colouration in mammals are very complex and controlled by hundreds of genes whose effects and interactions are still largely unclear. In this study, we adopted a robust multi-cohort Fst outlier approach based on pairwise contrasts between seven grey indicine cattle breeds and both taurine and indicine non-grey cattle breeds in order to find genomic regions potentially related to the grey colouration. On the basis of three main drawn settings, built in order to…
