Full textpurpose: To assess RNFL thickness in patients affected by multiple sclerosis, cis type and a disease-free control group by oct and gdxpro and to correlate the results of this two diagnostic tools. material and methods: 36 patients (72 eyes) affected by multiple sclerosis, cis type and 26 (52 eyes) disease-free patients were enrolled in the study; all the patients underwent RNFL thickness by OCT (OCT-3, OCT 4.0 software; Carl Zeiss Meditec, Dublin, California) and GDxPRO with variable corneal compensation (software 5.5.1, Carl Zeiss Meditec). results: mean (SD) rnfl thickness measured by oct was 100,4 à µ (12,2 à µ) in patients affected by CIS and 103,1 à µ (7,8 à µ) in the disease-free group, with no significative difference between the two groups (p = NS; t test). mean (SD) rnfl thickness measured by gdxpro was 51,6 à µ (4,1 à µ) in patients affected by CIS and 51,3 à µ (3,2 à µ) in the disease-free group, with no significative difference between the two groups (p = NS; t test). in cis group a significative correlation between mean rnfl thickness measured by oct and gdx (r = 0,40; p < 0,001) was demonstrated. In cis group mean rnfl measured by oct were normal in 64 eyes (88,8%) and reduced in 8 eyes (11.2%). in the disease-free group normal results were demonstrated in all eyes (100%). In cis group mean rnfl measured by gdxpro were normal in 65 eyes (90.3%) and reduced in 7 eyes (9.7%). in the desease-free mean rnfl were normal in 49 (94.3%) eyes and reduced in 3 (5.7%). conclusion: no significative difference in rnfl thickness between the two groups, measured by oct and gdx, was demonstrated; oct was more sensible in detecting a subtle rnfl atrophy.

Full textBragg gratings optical filters can be considered one of the key elements in many integrated optical devices such as wavelength-division multiplexing (WDM), optical fibre sensors, gain-flattening filters and add-drop multiplexers (OADM’s), optical couplers, resonators and modulators. Over the past decade, extensive research has been conducted in order to improve the unconventional fabrication techniques to obtain low-cost optical devices. Several Bragg gratings-based optical devices have been obtained by merging conventional and unconventional fabrication techniques. In my Phd, the device consists of a hybrid titanium (organic/inorganic Sol-Gel material) optical filter for the third’s telecommunication optical windows (1550 nm) based on Bragg gratings loaded channel waveguide. The fabrication of the device is obtained by merging conventional and unconventional technique. The unconventional fabrication technique is the Soft-Litography, a very innovative process based on Replica-molding and UV-nanoimprinting for micro- and nano- fabrication. This process is characterized by low cost and fast processing using relatively inexpensive tools. Starting from sub-micrometric gratings (master) fabricated on Silicon wafer by means of standard Electron Beam Lithography (EBL) a soft mold (stamp) has been produced by replica-molding. Using the stamp, the initial master structures (Bragg gratings) were replicated onto sol-gel photosensitive films by Uv-nanoimprinting. The resulting films underwent a further photolithographic step combined with Reactive Ion Etching (RIE), thus producing a channel waveguide with Bragg gratings on the top. This wavelength filter have been optically characterized by transmission measurements in the range 1450 nm – 1590 nm by a tuneable IR diode laser. The efficiency was about -10 dB and the bandwidth at Full Width Half Maximum (FWHM) 1,7 nm. So, Titanium based wavelength filters, obtained by the merging of conventional photolithography and Soft-Lithography, have been demonstrated. The use of sol-gel technology with S-L methods makes thus possible to produce passive optical devices starting from a hard silicon master. Furthermore, thanks to high versatility of S-L process, a consistent replica of the master optical filter (i.e. channel with Bragg gratings) allows to replicate the pattern (at the nanometric scale) directly on a new sol-gel planar film. The morphological characterization by Atomic force microscopy of the replicated structure (optical filter), shows a good agreement with the Master. In conclusion, this means that we have obtained a simple process, low cost and industrially advantageous, to fabricate nanostructures on Sol-Gel matrix.

Full textAim of the thesis was a detailed study of optical trapping of low index particles dispersed in liquid crystals. This phenomenon is completely different from conventional optical manipulation in isotropic media, related to intensity gradient forces. It is due, in fact, to the interaction, by means of elasticity of liquid crystals, between an optically distorted region around the trap and the colloid. The attractive force shows peculiar properties that come from the medium: it is anisotropic in space and characterized by a very long-range action. The analysis, carried out under experimental conditions that prevent the effect of conventional trapping, has highlighted the role of the nonlocality of optical reorientation by showing the dependence of the trapping force on the size of the reoriented area. A model for director configuration was proposed, based on the actual form of the Gaussian focused beam on the liquid-crystalline medium, with good agreement with experimental data.

Full textThe subject of this thesis concerns the Ottieriâ s literary work from his first novel Memorie dellâ incoscienza (1954) to Una irata sensazione di peggioramento (2002), analysing three themes which come over his poetry: industry, sanatorium and politics. The thesis is planned on seven chapters. In the introduction, the characteristics of Ottieriâ s novels are developed: original and unclassifiable, Ottieri has organized an extensive literary project through thirty works connected by a continuous plot of themes and leitmotivs which are linked on different subject as Italian and European literature, history, psychiatry, art, politics. In the first chapter, the Ottieriâ s youthful devotion to fascism is analysed in the light of his own memories (Memorie dellâ incoscienza), an autobiographic novel in which an alter ego (Lorenzo Bandini) analyses the dramatic issues of Italy during the Second World War. In the second chapter the emergent theme concerns the industrial world through four works (two novels: Tempi stretti and Donnarumma allâ assalto, the diary La linea gotica and the play I venditori di Milano) which allow him to be the â pioneerâ of Italian industrial literature. From the third to the fifth chapter, the principal theme which comes over is mental illness; depression, schizophrenia, alienation are bound to be the centre of his literary works and not only of his life. The sixth chapter studies two novels, La storia del PSI and Il poema osceno, which are the summary of his political ideas. The seventh chapter is about the last works of Ottieri; aware of his imminent death, the poet describes his life as a borderline individual and as an unsuccessful writer.
