Assembly, growth and conductive properties of tellurium nanorods produced by Rhodococcus aetherivorans BCP1
2018
AbstractTellurite (TeO32−) is a hazardous and toxic oxyanion for living organisms. However, several microorganisms can bioconvert TeO32− into the less toxic form of elemental tellurium (Te0). Here, Rhodococcus aetherivorans BCP1 resting (non-growing) cells showed the proficiency to produce tellurium-based nanoparticles (NPs) and nanorods (NRs) through the bioconversion of TeO32−, depending on the oxyanion initial concentration and time of cellular incubation. Te-nanostructures initially appeared in the cytoplasm of BCP1 cells as spherical NPs, which, as the exposure time increased, were converted into NRs. This observation suggested the existence of an intracellular mechanism of TeNRs assem…
Resting-state posterior alpha rhythms are abnormal in subjective memory complaint seniors with preclinical Alzheimer's neuropathology and high educat…
2020
International audience; Cognitive reserve is present in Alzheimer's disease (AD) seniors with high education attainment making them clinically resilient to extended brain neuropathology and neurodegeneration. Here, we tested whether subjective memory complaint (SMC) seniors with AD neuropathology and high education attainment of the prospective INSIGHT-preAD cohort (Paris) may present abnormal eyesclosed resting state posterior electroencephalographic rhythms around individual alpha frequency peak, typically altered in AD patients. The SMC participants negative to amyloid PET AD markers (SMCneg) with high (over low-moderate) education level showed higher posterior alpha 2 power density (pos…
La digitalizzazione del patrimonio come strumento per la conoscenza, un’esperienza sull’architettura ferroviaria siciliana
2022
The process of digitisation of the artistic and cultural heritage has enriched the possibilities of representation and communication of architecture, increasing the modes of reproduction, fruition as well as the possibilities of protection and preservation. The study of this research draws attention on the continuous progress of technology in the cultural field and highlights the important collaboration that exists between digital and analog representation, identifying, with this synergy, a virtuous path that allows, through the use of different methodologies, to be able to know and analyze the historical phases of a building. In particular, the attention was directed to the Caltanissetta C…
From Image to Investigation 3D Reconstruction with Perspective Restitution
2022
The memory of hundreds gone buildings is preserved by few photographic images. Perspective restitution with digital representation tools can be used today to reconstruct these buildings directly in 3D space. Digital representation has overcome many limitations that affected perspective restitution in the pre-digital era. In this paper the inner space of the church of San Michele in Trapani, destroyed at the end of the 50’, is reconstructed with the aid of three period photographic images. Some architectural elements that escaped destruction and are today located in a new church near Trapani have been surveyed with laser scanning and SfM photogrammetric techniques. Surveyed elements provided…
Resting Energy expenditure in type 2 diabetic patients and the effect of insulin bolus
2014
Aims: Resting energy expenditure (REE) plays a critical role in the regulation of body weight, with important implications in type 2 diabetes (T2D). However, the relationships between REE and T2D have not been extensively evaluated. We compared REE in persons with diabetes and in persons without diabetes. We also investigated the acute effect of insulin on REE and venous lactate, the latter an indirect measure of neoglucogenetic activity. Methods: REE was measured using indirect calorimetry in 14 newly diagnosed, untreated T2D adults and in 14 non-diabetic age-, gender- and body mass index-matched persons. The REE and lactate venous concentrations were also measured in a subgroup of 5 T2D p…
A ballistometer for the study of the plasto-elastic properties of skin.
1977
The ballistrometer is based on the "drop impact" of a body onto a stationary surface. A collision in one dimension is provoked by allowing a bard body to drop from a given height onto the skin surface to be tested. After the collision, the impacting body undergoes a variable number of rebounds decreasing in amplitude. By measuring the height of the rebounds, the amount of energy returned by the tissue is calculated in terms of coefficient of restitution e. The equipment, consisting of a hammer unit, a feeder-amplifier, and a plotter, is described. Ballistometry has been carried out on skin areas of 46 normal subjects ranging in age from 8 to 80 years, as well as on pathologic and cadaveric …
Metodi per la ricostruzione virtuale e la visualizzazione di opere d'architettura perdute
2022
Digital technologies for architecture representation have strongly modified uses and rules inherited from a millennial tradition. In the initial development period CAD tools worked as electronic drafting machines and digital drawings were almost similar to hand-made drawings; plans, fronts, sections and the like. In this period perspective and axonometric drawings were rarely executed because architects realized that these drawings had to be substituted by 3D digital models views, but modeling tools were not so familiar to professionals, both for software and hardware limitations. The evolution of architecture digital representation is still in progress, but it is possible to outline a prec…
Ladri di luce. Leonardo Sciascia e Piero Guccione tra bellezza e verità
2023
The unpublished correspondence between Leonardo Sciascia and Piero Guccione from 1975 to 1989 shows the profound charge of humanity that innervates the friendship between these two great Enlightenment leaders "upside down". A "correspondence of amorous senses", despite the inevitable ideological differences, which the letters reproduced here for the first time and the original contributions of the volume give us back, under the banner of the binomial "beauty-truth".
Optimal damping coefficient for a class of continuous contact models
2020
AbstractIn this study, we develop an analytical formula to approximate the damping coefficient as a function of the coefficient of restitution for a class of continuous contact models. The contact force is generated by a logical point-to-point force element consisting of a linear damper connected in parallel to a spring with Hertz force–penetration characteristic, while the exponent of deformation of the Hertz spring can vary between one and two. In this nonlinear model, it is assumed that the bodies start to separate when the contact force becomes zero. After separation, either the restitution continues or a permanent penetration is achieved. Therefore, this model is capable of addressing …
