Multidisciplinary Approach for Evaluating the Geochemical Degradation of Building Stone Related to Pollution Sources in the Historical Center of Napl…

2020

Natural stones have represented one of the main building materials since ancient times. In recent decades, a worsening in degradation phenomena related mostly to environmental pollution was observed, threatening their conservation. The present work is focused on the minero-petrographic and geochemical characterization of black crust (BC) samples taken from the historical center of Naples, after selecting two pilot monumental areas. The latter were chosen based on their historical importance, type of material, state of preservation and position in the urban context (i.e., high vehicular traffic area, limited traffic area, industrial area, etc.). The building materials used and their interact…

Covalently Binding of Bovine Serum Albumin to Unsaturated Poly(Globalide-Co-ε-Caprolactone) Nanoparticles by Thiol-Ene Reactions.

2019

When nanoparticles (NPs) are introduced to a biological fluid, different proteins (and other biomolecules) rapidly get adsorbed onto their surface, forming a protein corona capable of giving to the NPs a new "identity" and determine their biological fate. Protein-nanoparticle conjugation can be used in order to promote specific interactions between living systems and nanocarriers. Non-covalent conjugates are less stable and more susceptible to desorption in biological media, which makes the development of engineered nanoparticle surfaces by covalent attachment an interesting topic. In this work, the surface of poly(globalide-co-e-caprolactone) (PGlCL) nanoparticles containing double bonds i…

The New Life Of Exhausted Bentonite From The Grape Processing Industry: From Waste To Precious Resource To Produce Novel Raw Materials Enriched In Po…

Introduction: In an ever-growing perspective of circular economy, the development of conscious, sustainable and environmental-friendly strategies to recycle the waste products is the key point1. The exhausted bentonite, from the grape processing industries, could become a precious matrix to produce new pharmaceutical/cosmetic excipients enriched in functional polyphenols2. Materials & Methods: The exhausted bentonite recovered after the fining process (supplied by Bono&Ditta s.p.a., Campobello di Mazara TP, Italy) was stored at -20°C. Solid-liquid extractions on both freeze-dried and as-collected (wet) bentonite were carried out by using PEG200 or propylene glycol as solvents. The l…

Antioxidant activity of TunisianGeranium robertianumL. (Geraniaceae)

2013

The present investigation focuses on the methanolic extract obtained from Geranium robertianum L. (Geraniaceae) (Herb Robert), a herbal plant used in traditional medicine for the treatment of human and animal diseases. The antioxidant capacities of the extract were evaluated using 1,1-diphenyl-2- picrylhydrazyl radical, β-carotene/linoleic acid and reducing power and metal chelating activity assays. The amount of total phenolic content, flavonoids and condensed tannins was very high, and the correlation between the antioxidant activity potential and total phenolic level of the extract was pointed out.

Poverty as failed exercise of rights? Some theoretical problems

2007

A state of deprivation can be epitomised as a situation that implies not only a lack of resources but even a failed exercise of individual rights. Sometimes, if we consider poor exclusively those who have not enough money we may miss part of the picture or we may pursue inefficient and/or unjust policies. Let us think of handicapped persons that have a certain income; this sum may be enough for healthy people, but it is not the case for those who are not self-sufficient. Thus, we may have people poor and people not poor with the same amount of resources. Poverty, then, must be considered not as a lack of resources but as the difficulty of enjoying relevant opportunities (e.g. reading, writi…

A Sociocultural Approach to Children’s Visual Creations

2021

AbstractThis chapter locates the book within the research on children’s art. It explores interpretations of children’s visual creations throughout the twentieth century and situates the approach of the book within the research landscape. The authors take developmental psychological, educational, and aesthetic approaches to form a sociocultural view of children’s art, challenging many of the previous research assumptions. Through adopting the paradigm of the sociocultural approach, the authors embrace its view of children as competent cultural actors and active participants in cultural production. Thus, the discussion focuses on meaning-making: the authors analyze visual artifacts made by st…

Pluriversalizar los regímenes globales de conocimiento: ¿Puede el Análisis del Discurso sociológico contribuir a estudios Decoloniales?

2020

In this paper we discuss the perspective of Sociology of Knowledge Approach to Discourse (SKAD) as a possible strategy applicable to studies framed by decolonial thought. The reflection is approached by comparing key concepts of both perspectives, such as discourse, power and knowledge, as well as their methodological premises. The results allow us to point out potentials of SKAD as a conceptual-methodological reference for investigations towards decoloniality, e.g. the SKAD analysis dimensions patterns of interpretation and narrative structure. However, possible limitations of the SKAD with respect to the design and the realization of decolonial studies were also revealed, particularly in …

Approximate Bayesian Computation for Forecasting in Hydrological models

2018

Approximate Bayesian Computation (ABC) is a statistical tool for handling parameter inference in a range of challenging statistical problems, mostly characterized by an intractable likelihood function. In this paper, we focus on the application of ABC to hydrological models, not as a tool for parametric inference, but as a mechanism for generating probabilistic forecasts. This mechanism is referred as Approximate Bayesian Forecasting (ABF). The abcd water balance model is applied to a case study on Aipe river basin in Columbia to demonstrate the applicability of ABF. The predictivity of the ABF is compared with the predictivity of the MCMC algorithm. The results show that the ABF method as …

Urticaria in Pediatrics and During Pregnancy and Lactation: Highlights on Epidemiology, Diagnosis, and Management

2021

Chronic urticaria (CU) in children as in adults is characterized by the presence of itchy wheals, angioedema, or both daily or almost daily for at least 6 weeks. Most cases of urticaria in the pediatric age group are acute [1–4]. CU is sub-classified as spontaneous (occurring without a known trigger) or inducible. There are also cases of spontaneous and inducible forms that co-exist. The chronic subtypes occur continuously but also recurrently, often in association with infections. In this chapter we will touch briefly on the clinical presentation, diagnosis, and management of acute urticaria in children. However, our primary goal is to highlight key findings regarding the epidemiology, dia…

Prenatal diagnosis of cerebral malformation with an uncertain prognosis: a study concerning couple's information and consequences on pregnancy.

2004

Abstract Fetal ultrasound (FU) is used during almost all pregnancies and makes a large contribution to the identification of fetal malformation. It is particularly difficult to announce a malformation, particularly those affecting the brain, because there are often doubts concerning both the diagnosis and the prognosis. Aim. – The aim of this study was to analyze how imaging for prenatal screening is organized and how couples are managed and supported. We concentrated on the procedures used to inform couples: content, method of delivery and consequences. Method. –: Study amongst large multidisciplinary centers in Paris and the Paris region, by semi-directed interviews using a questionnaire.…
