A multi-generational study on low-dose BPA exposure in Wistar rats: Effects on maternal behavior, flavor intake and development
2012
Bisphenol A (BPA) is a common endocrine disruptor found as an environmental and food contaminant. It exerts both developmental and behavioral effects, mainly when exposure occurs in early life. The aim of this study was to determine the multi-generational effects of chronic, human-relevant low-dose exposure to BPA on development, maternal behavior and flavor preference in Wistar rats. BPA was orally administered at a daily dose of 5 mu g/kg body weight to FO pregnant dams from the first day of gestation (GD 1) until the last day of lactation (LD 21), and then to Fl offspring from weaning (PND 21) to adulthood (PND 100). F2 offspring were not exposed. Development and clinical signs of toxici…
The long-term outcome of 2 family intervention strategies in schizophrenia.
2006
The different family-based interventions that have proven to be effective in treating people with schizophrenia present some therapeutic elements in common and differ in certain other respects, although to date, none of the proposed approaches have demonstrated to be clearly superior to each other in reduced relapse and readmission rates. Although the approaches based on relatives group therapies save considerable amounts of time, some data reveal better short-term results when the intervention focuses on the family unit and the participant patient. Objective: The aim of this study was to determine whether the clinical and social benefits observed in the short term would be maintained 5 yea…
Eco depletion: The impact of hunger on prosociality by means of environmentally friendly attitudes and behavior
2021
Abstract The present research investigated the impact of hunger on prosociality in a consumer choice context by means of environmentally friendly attitudes and behavior. Two eye-tracking studies were conducted with hunger measured (Study 1) and manipulated (Study 2). The data were analyzed through bivariate correlations, Pearson's chi-square tests, and analyses of variance (ANOVAs). Our findings, based on cross-sectional and experimental evidence from field and lab settings, revealed that hungry consumers express more prosocial attitudes than their satiated counterparts in terms of general environmental concerns and importance ratings of buying eco-labeled products. However, we found no sig…
Biodegradable Polymers for the Production of Nets for Agricultural Product Packaging
2021
It is well known that the need for more environmentally friendly materials concerns, among other fields, the food packaging industry. This regards also, for instance, nets used for agricultural product (e.g., citrus fruits, potatoes) packaging. These nets are typically manufactured by film blowing technique, with subsequent slicing of the films and cold drawing of the obtained strips, made from traditional, non-biodegradable polymer systems. In this work, two biodegradable polymer systems were characterized from rheological, processability, and mechanical points of view, in order to evaluate their suitability to replace polyethylene-based polymer systems typically used for agricultural prod…
A New Environmentally-Friendly Colorimetric Probe for Formaldehyde Gas Detection under Real Conditions
2018
[EN] A new environmentally-friendly, simple, selective and sensitive probe for detecting formaldehyde, based on naturally-occurring compounds, through either colorimetric or fluorescence changes, is described. The probe is able to detect formaldehyde in both solution and the gas phase with limits of detection of 0.24 mM and 0.7 ppm, respectively. The probe has been tested to study formaldehyde emission in contaminated real atmospheres. The supported probe is easy to use and to dispose, and is safe and suitable as an individual chemodosimeter.
Hydrothermal synthesis of nanostructured zirconia materials: Present state and future prospects
2005
Abstract Hydrothermal procedures for the synthesis of zirconia-doped nanocrystalline powders show important advantages from the thermodynamic and kinetic point of view (larger domain stability of solid species, faster kinetics crystallisation) as well as from technological point of view (one-step synthesis process at low temperatures, better control of the crystallisation and grain sizes with possibilities to obtain nanocrystalline materials, versatility, environmental friendly technology). Establishment of the conditions for obtaining ZrO2-doped with different oxides is based on thermodynamic predictions. Kinetic modelling of the hydrothermal synthesis of zirconia nanopowders is presented.…
Quality Control of Agrochemical Formulations by Diffuse Reflectance near Infrared Spectrometry
2008
A near infrared (NIR)-based methodology has been developed for the determination of 11 pesticides in commercially available formulations. This solvent free, fast and environmentally friendly method was based on the direct measurement of the diffuse reflectance spectra of solid samples, a hierarchical cluster classification and the use of multivariate calibration models to determine each considered active principle in agrochemicals. The proposed partial least squares (PLS) models used for quantification of each compound were built from specific calibration sets composed of nine spectra corresponding to triplicate measurements of a single well characterised commercial sample and two addition…
Pickering Emulsions Based on Wax and Halloysite Nanotubes: An Ecofriendly Protocol for the Treatment of Archeological Woods
2020
A novel green protocol for the consolidation and protection of waterlogged archeological woods with wax microparticles has been designed. First, we focused on the development of halloysite nanotubes (HNTs) based Pickering emulsions using wax as the inner phase of the oil-in-water droplets. The optimization of the preparation strategy was supported by both optical microscopy and scanning electron microscopy, which allowed us to show the morphological features of the prepared hybrid systems and their structural properties, i.e., the distribution of the clay at the interface. Also, the dependence of the overall dimensions of the prepared systems on the halloysite content was demonstrated. Micr…
Hell on earth: Textual reflections on the experience of mental illness
2012
Background: Some people who by themselves or by others are understood as having mental health problems have written autobiographies about their experiences. Aims: The aim of this study is to explore how people write about their experiences of being mentally ill. Method: Twelve Scandinavian autobiographies were studied using content analysis based on phenomenology and hermeneutics. Results: Three themes were identified: feeling like a stranger in life and places, the transformation of life experiences into questions of disease and feeling ashamed. Conclusions: People’s experiences of being mentally ill might be understood as the result of medical constructions unsuitable for the persons them…
Scalable and effective multi-level entangled photon states: a promising tool to boost quantum technologies
2021
Abstract Multi-level (qudit) entangled photon states are a key resource for both fundamental physics and advanced applied science, as they can significantly boost the capabilities of novel technologies such as quantum communications, cryptography, sensing, metrology, and computing. The benefits of using photons for advanced applications draw on their unique properties: photons can propagate over long distances while preserving state coherence, and they possess multiple degrees of freedom (such as time and frequency) that allow scalable access to higher dimensional state encoding, all while maintaining low platform footprint and complexity. In the context of out-of-lab use, photon generation…
