Water detection in skin by dual-band photodiodes
2013
Purpose of this study was to develop a simple model for possibilities to detect water in skin by diffuse reflectance spectra. The model is based on comparison of diffuse reflectance spectra when illuminating water sample with LEDs of different wavelengths (1200 nm, and 1450 nm). The illumination LEDs were chosen due to water absorption differences in near-infrared spectral range. For detection, dual-band photodiode DSD2 by Thorlabs was used. Due to differences of water absorption at different wavelengths in the near-infrared spectral region, this correlation could be used for mapping of water content in skin or, in other words, determine relative moisture level in skin. Simple experimental …
Aryl hydrocarbon receptor-dependent cell cycle arrest in isolated mouse oval cells
2013
The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor, which mediates toxic responses to environmental pollutants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related compounds. Besides its well known role in induction of xenobiotic metabolizing enzymes, for instance CYP1A1, the AhR is also involved in tumor promotion in rodents although the underlying mechanisms are still poorly understood. Additionally, the AhR is known to regulate cellular proliferation, which might result in either inhibition or stimulation of proliferation depending on the cell-type studied. Potential targets in hepatocarcinogenesis are liver oval (stem/progenitor) cells. In the pres…

Modification of a commercial atomic force microscopy for low-noise, high-resolution frequency-modulation imaging in liquid environment.
2011
A key issue for high-resolution frequency-modulation atomic force microscopy imaging in liquids is minimizing the frequency noise, which requires a detailed analysis of the corresponding noise contributions. In this paper, we present a detailed description for modifying a commercial atomic force microscope (Bruker MultiMode V with Nanoscope V controller), aiming at atomic-resolution frequency-modulation imaging in ambient and in liquid environment. Care was taken to maintain the AFMs original stability and ease of operation. The new system builds upon an optimized light source, a new photodiode and an entirely new amplifier. Moreover, we introduce a home-built liquid cell and sample holder …
La passione dell’odio e la violenza correttiva. Greci e Cartaginesi in Sicilia (409-396 a.C.)
2010
Gli sguardi sul passato e sul presente sono sempre legati tra loro e condizionati dai rapporti di forza prevalenti nelle società che li producono. Ci si sofferma sul gioco del ≪va e vieni≫ tra il passato, oggetto della narrazione, e lo sguardo che a quel passato rivolge Diodoro. E a questi due livelli inseparabili che si colloca, a mio avviso, il senso di un insieme di narrazioni relative agli assedi di Selinunte e Mozia, tra V e IV sec. a.C., che mirano a chiarire al pubblico della Biblioteca questo legame tra passato e presente. Ci si concentra sul problema del confine e della separazione: confini dissolti dall’assedio, dalla crudeltà, dall’oltraggio, dalla confusione tra dentro e fuori, …

THE SILICON PHOTOMULTIPLIER:AN IN-DEPTH ANALYSIS IN THE CONTINUOUS WAVE REGIME
2014
The Silicon Photomultiplier (SiPM) is a novel solid state photon counting detector consisting of a parallel array of avalanche photodiodes biased beyond their breakdown voltage. It has known a fast development in the last few years as a possible alternative to vacuum photomultiplier tubes (PMTs) and conventional avalanche photodiodes (APDs). Indeed, current research in photodetectors is directed toward an increasing miniaturization of the pixel size, thus both improving the spatial resolution and reducing the device dimensions. SiPMs show high photon detection efficiency in the visible and near infrared range, low power consumption, high gain, ruggedness, compact size, excellent single-phot…
Le parole dell'odio. Dal lessico alle pratiche verbali
2017
Argomento dell'articolo è il fenomeno dello "hate speech" (discorso d’odio). La tesi che si sostiene è che tale fenomeno può essere meglio compreso se si parte dal mettere in discussione la netta distinzione tra una tra forma di violenza puramente ‘fisica’ e una puramente ‘verbale’ e si cerca, invece, di mettere a fuoco l’intreccio tra verbalità e violenza nell’essere umano, domandandosi se, ed eventualmente in che modo, il fatto di essere" animali parlanti" modifichi anche il nostro modo di essere violenti. Per fare questo, occorre superare un approccio puramente lessicale o semantico al fenomeno e inserire invece le parole d'odio nelle concrete pratiche verbali nelle quali esse sono utili…
Prolonged stigma and flower lifespan in females of the gynodioecious plant Geranium sylvaticum
2017
In gynodioecious plants females need a reproductive advantage over hermaphrodites to be maintained in the same population. Generally, three main proximate causes for a female advantage are considered: inbreeding avoidance, different resource allocation patterns, and differences in ecological interactions. A mechanism potentially causing a female advantage that is rarely discussed is a difference in floral longevity between the genders. Females may have a longer stigma lifespan than hermaphrodites, which can affect pollination. Stigma and flower lifespan are rarely documented in gynodioecious species, although it is a common observation in dioecious species that female plants flower longer t…
