Faraday effect in standard optical fibers: dispersion of the effective Verdet constant

1996

We have measured the Faraday effect in silica standard optical fibers in the wavelength range 458-1523 nm. An effective Verdet constant Vef that exhibits a linear dependence on the square of the optical frequency ν is defined: V(ef) = (0.142 ± 0.004) × 10(-28) ν(2) rad T(-1) m(-1). We demonstrate that the negative effects of a small linear birefringence can be minimized by adjustment of the input polarization to an optimum state.

Optical rotary power at the resonance of the Terbium 7F6→5D4 line in Terbium Gallium Garnet

1998

Abstract The Tb 3+ absorption line 7 F 6 → 5 D 4 of the Terbium Gallium Garnet crystal is excited with an Argon ion laser. The Verdet's constant has been determined and reported against 1/ λ 2 , showing no significant resonant behaviour at absorption resonance. The utility and the constraints of the crystal at this particular resonant wavelength are pointed out.

TOWARD A SOLUTION OF ALLOCATION IN LIFE CYCLE INVENTORIES: THE USE OF LEAST SQUARES TECHNIQUES

2010

Purpose: The matrix method for the solution of the so-called inventory problem in LCA generally determines the inventory vector related to a specific system of processes by solving a system of linear equations. The paper proposes a new approach to deal with systems characterized by a rectangular (and thus non-invertible) coefficients matrix. The approach, based on the application of regression techniques, allows solving the system without using computational expedients such as the allocation procedure. Methods: The regression techniques used in the paper are (besides the ordinary least squares, OLS) total least squares (TLS) and data least squares (DLS). In this paper, the authors present t…

A rigidity problem on the round sphere

2015

We consider a class of overdetermined problems in rotationally symmetric spaces, which reduce to the classical Serrin's overdetermined problem in the case of the Euclidean space. We prove some general integral identities for rotationally symmetric spaces which imply a rigidity result in the case of the round sphere.

The method of moving planes: a quantitative approach

2018

We review classical results where the method of the moving planes has been used to prove symmetry properties for overdetermined PDE's boundary value problems (such as Serrin's overdetermined problem) and for rigidity problems in geometric analysis (like Alexandrov soap bubble Theorem), and we give an overview of some recent results related to quantitative studies of the method of moving planes, where quantitative approximate symmetry results are obtained.

Installazione di un tetto verde multistrato in un tipico ambiente urbano del sud Italia

Il verde pensile è un sistema tecnologico che prevede l’utilizzo della vegetazione come strato superiore della copertura di un edificio, impiegato sia per le sue funzioni ambientali che per le sue caratteristiche estetiche (Cascone, 2019). Infatti, la realizzazione di un tetto verde, oltre al suo intrinseco valore ecologico, consente numerosi vantaggi economici ed ambientali rispetto alle coperture tradizionali (Berardi & Ghaffarianhoseini, 2014). Nel tempo, l’interesse nei confronti dei tetti verdi è sempre più cresciuto, sia per i benefici conseguibili che rispondono a molti degli obiettivi delle diverse politiche nazionali, europee e internazionali per la mitigazione e l’adattamento …

Palermo, Giovan Battista Nolli e una pianta del verde

2021

L’infezione su scala globale, generata dal virus SARS–Cov–2, ha evidenziato questioni inevase da qualche tempo causate dagli effetti di un costante ed inesorabile processo di inurbamento e dalla conseguente difficile interazione tra centri urbani e campagna. Rispetto alla prima questione con la pandemia sembra, per la prima volta, dalla rivoluzione industriale, alterarsi la “gravità terrestre” dando vita ad una dinamica che modifica quel movimento a senso unico verso i grandi centri. Si profila una nuova e differente dispersione che scaturisce dalla esigenza di vivere in luoghi più salubri preferendo abitazioni forse non necessariamente unifamiliari ma incluse in sistemi insediativi lontani…
