Multivariate geophysical survey to detect a shallow fault zone in a landfill project area
2018
An integrated analysis of 2D high-resolution shallow seismic refraction tomographies (SRT) and electrical resistivity tomographies (ERT) has been carried out along a slope where the presence of a fault zone was assumed. It was also applied a post-inversion k-means cluster analysis of the P-wave velocity, the density of the seismic rays and the electrical resistivity of the interpretation models. Distribution maps of the cluster in multi-space were built, allowing to better definethe lateral geometry of a NE-SW directed band composed of intensely tectonized carbonate breccias. Finally, the fracturing and kinematic analysis on fault planes observed along the trenches, highlighted systems of l…

On cosmetically treated hair — aspects and pitfalls of interpretation
1997
Popular hair cosmetic treatments like bleaching or permanent waving were found to affect the stability of incorporated drugs and to cause alterations of the fibers at an ultrastructural level. This may result in a partial or complete loss of drug substances, depending on the particular drug molecule and on its concentration prior to the cosmetic treatment. Moreover, from literature, there is some evidence that drug molecules are not only incorporated into the growing fiber by passive diffusion from blood into the matrix cells and melanocytes, but that the substances enter the hair also via perspiration such as sweat and sebum. Since permed and bleached hair shows an enhanced sorption capaci…
Stability of opiates in hair fibers after exposure to cosmetic treatment.
1996
Abstract The stability of opiates in clipped natural human hair was investigated. Hair fibers were incubated with defined solutions of morphine, codeine and dihydrocodeine (pH 7.4) until saturated. Original opiate-positive hair samples collected from drug addicts also were examined. Commercially available bleaching as well as perming formulas (Poly Blonde Ultra®, Poly Lock®; Henkel, Dusseldorf, Germany) were applied in vitro to the hair strands of both groups under investigation. After these treatments, the drug concentration had decreased for both bleaching and permanent waving. In the spiked hair, only 2–18% of the starting solution could be found after bleaching. About 20–30% of the drug…
Kairos, the decisive moment
2015
En este artículo haremos un recorrido conceptual por el término y las problemáticas de la fotografía, utilizando la figura de Cartier-Bresson como hilo conductor. Tras intentar determinar las características que la definen, analizaremos la relación de la misma con la pintura; trataremos de ver, a continuación, diferentes opiniones y posturas acerca de si puede o no considerarse arte; y apuntaremos, en última instancia, ciertos cambios en el concepto de belleza que ha conllevado esta nueva forma de reproducir el mundo. : In this article we will explore the concept and problems of photography, using the figure of Cartier-Bresson as the thread that runs through the entire essay. After trying t…

I Peralta e il Val di Mazara nel XIV e XV secolo: sistema di potere, strategie familiari e controllo territoriale
2003
Il volume apre nuove valutazioni sulla situazione socio-politica della Sicilia del XIV-XV secolo offrendo uno spaccato di un'epoca ambigua che vede, accanto alla presenza quanto meno nominale della monarchia, il nascere di signorie che gestiscono il potere. Attraverso l’esame di documenti inediti di archivi pubblici e privati, il libro ricostruisce la genealogia e la storia di una famiglia che, trapiantatasi in Sicilia nei primi del Trecento, forte della consanguineità con i regnanti, si è radicata nel territorio isolano attraverso un’oculata politica matrimoniale, riuscendo ad assumere un ruolo sempre più determinate nelle vicende isolane e creando una “signoria”, dotata di una propria cor…

ERT and IPT surveys to check the integrity of the geomembrane in the landfill of Bellolampo (Palermo, Italy)
2016
In landfills, changes in resistivity and chargeability can be related to the characteristics of the waste and they can be abrupt and considerable within short distances. These physical properties are function of generation, mobility and degree of saturation of the leachate, gas generation, compaction density and variability. These relationships mean that it can be possible to get an overall image of the quantity and characteristics of the waste from surface electrical measurements over the landfill. In this paper, we present and discuss the results of three electrical tomographies carried out in the landfill site of Bellolampo (Palermo, Italy). The main aim of these surveys was to check the…
Lack of antiandrogenic effects of topical bifonazole on sebaceous glands and hairs in the hamster flank organ.
1993
The activity of topically applied bifonazole was evaluated in vivo in the three androgen-dependent structures of the hamster flank organ, i.e. the pigmented spot, sebaceous glands and hairs. Topical bifonazole in our experience did not demonstrate any morphological effect on sebaceous gland and hair even when applied in the dosage of 3 mg/cm<sup>2</sup>/day. On the basis of our morphometric results we can conclude that topically applied bifonazole does not interfere with cutaneous androgen metabolic transformations in the pilosebaceous unit of the flank organ.
