Supra-aggregates of fiber-forming anisotropic molecules.
2006
In this paper, the self-organization of fiber-forming anisotropic molecules is inspected both theoretically and experimentally. In the first part, a theoretical model which extends the de Gennes theory of thin films to assemblies of strongly anisotropic molecules is reported. The model predicts that solid supported thin films made up of fiber-forming discotic molecules can grow with both tangential and radial arrangement of the fibers, respectively leading to the formation of compact and holed supra- aggregates. These last systems form according to the following picture. The tangential growth minimizes the number of unfavorable free ends but introduces elastic strain especially in the centr…
A Comparative Study of Soil Suction Measurement Using Two Different High-Range Psychrometers
2007
An extensive experimental study was performed to compare the measurement capabilities within different ranges of two total suction measurement equipment: SMI transistor psychrometers and a chilled-mirror dew-point psychrometer (WP4 Dewpoint PotentiaMeter). The equipment were used in a systematic way to determine the relative humidity of the environment surrounding different compacted clayey soils along drying paths and covering a wide total suction range (0.1 to 70 MPa). The equipment description and the calibration protocols followed are presented, as well as suggestions regarding the improvement of their performance. The water retention curves of two different compacted clayey soils are p…
Temperature dependence of surface reorganization characteristics of amphiphilic block copolymer in air and in water studied by scanning force microsc…
2015
We have investigated the surface reorganization characteristics of a novel amphiphilic diblock copolymer, poly(acetic acid-2-(2-(4-vinyl-phenoxy)-ethoxy)-ethylester)-block-polystyrene (PAEES-b-PS), in response to varying interfaces from air to water and vice-versa at various temperatures. The surface reorganization characteristics of the block copolymer films was monitored by scanning force microscopy, in order to delineate the kinetically controlled morphological process of surface reorganization of a diblock copolymer, with a particular emphasis on the phase contrast signal which allowed the determination of local composition patterns of PAEES-b-PS at the surface. Upon heating a water-an…
Deep Gaussian Processes for Geophysical Parameter Retrieval
2018
This paper introduces deep Gaussian processes (DGPs) for geophysical parameter retrieval. Unlike the standard full GP model, the DGP accounts for complicated (modular, hierarchical) processes, provides an efficient solution that scales well to large datasets, and improves prediction accuracy over standard full and sparse GP models. We give empirical evidence of performance for estimation of surface dew point temperature from infrared sounding data.
On dewetting dynamics of solid films of hydrogen isotopes and its influence on tritium [Beta] spectroscopy
2000
The dewetting dynamics of solid films of hydrogen isotopes, quench-condensed on a graphite substrate, was measured at various temperatures below desorption by observing the stray light from the film. A schematic model describing the dewetting process by surface diffusion is presented, which agrees qualitatively with our data. The activation energies of different hydrogen isotopes for surface diffusion were determined. The time constant for dewetting of a quench-condensed T2 film at the working temperature of 1.86 K of the mainz neutrino mass experiment was extrapolated.
Editorial: Sustainable development of energy, Water and Environment Systems
2020
In 2018 the Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES) was held in three different locations and periods, so as to offer to the scientific community working in the field several opportunities to share and discuss new ideas and disseminate results of research activities. The 1st Latin American SDEWES Conference was held in Rio de Janeiro (Brasil) in January 28–31 and attracted 180 scientists from 35 countries, with a high number of contributions mainly from Southern American and European academics and professionals, who reciprocally enriched about emerging issues in the field of sustainable development in these continents. Also, the participants a…
Sustainable and cost-efficient energy supply and utilisation through innovative concepts and technologies at regional, urban and single-user scales
2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
Reflektiivisyys ja ajattelun ajatteleminen lukiofilosofiassa
2023
Filosofian oppiaineeseen on aina liitetty lupaus ajattelutaitojen ja itsereflektiivisen ajattelun harjaannuttamisesta. Myös kasvatuksen teoriassa kriittiselle itsereflektiolle on annettu suuri merkitys niin oppimisessa yleisesti kuin uskomusten ja tottumusten uudistumiseen vaikuttavassa kokemuksellisessa oppimisessa erityisesti. Perustelemme reflektiivisyyden tärkeyttä filosofianopetuksessa John Deweyn ja Jack Mezirowin näkemyksillä. Filosofian opettajille on ollut tarjolla vain vähän ainedidaktisia välineitä tukea opiskelijoiden ajattelun itsereflektiota. Analysoimme artikkelissa filosofianopetuksen kokeilua, jossa lukiolaisia ohjattiin ajattelutaitojen itsereflektioon käyttämällä filosofi…

L’università italiana verso Europa 2020
2013
L'università italiana e la sfida di Europa2020" intende realizzare un'indagine approfondita dei processi di riforma e di adattamento al contesto europeo e internazionale intrapresi dal sistema universitario italiano a partire dagli anni '90, processi culminati nella L. 240/2010 "Norme in materia di organizzazione delle Università, di personale accademico e reclutamento, nonché delega al Governo per incentivare la qualità e l'efficienza del sistema universitario", e più in generale nell'esigenza di ridisegno del sistema secondo principi di efficacia, efficienza e coesione. Il volume studia il percorso di implementazione della riforma da parte degli atenei e l'inserimento nel sistema italiano…
