The XII century towers, a benchmark of the Rome countryside almost cancelled. The safeguard plan by low cost uav and terrestrial DSM photogrammetry surveying and 3D Web GIS applications
âGiving a bird-fly look at the Rome countryside, throughout the Middle Age central period, it would show as if the multiple city
towers has been widely spread around the territoryâ on a radial range of maximum thirty kilometers far from the Capitol Hill center
(Carocci and Vendittelli, 2004).
This is the consequence of the phenomenon identified with the âIncasalamentoâ neologism, described in depth in the following
paper, intended as the general process of expansion of the urban society interests outside the downtown limits, started from the half
of the XII and developed through all the XIII century, slowing down and ending in the following years. From the XIX century till
today the architectural finds of this reality have raised the interest of many national and international scientists, which aimed to study
and catalog them all to create a complete framework that, cause of its extension, didnât allow yet attempting any element by element
detailed analysis. From the described situation has started our plan of intervention, we will apply integrated survey methods and
technologies of terrestrial and UAV near stereo-photogrammetry, by the use of low cost drones, more than action cameras and reflex
on extensible rods, integrated and referenced with GPS and topographic survey. In the final project we intend to produce some 3D
scaled and textured surface models of any artifact (almost two hundreds were firstly observed still standing), to singularly study the
dimensions and structure, to analyze the building materials and details and to formulate an hypothesis about any function, based even
on the position along the territory. These models, successively georeferenced, will be imported into a 2D and 3D WebGIS and
organized in layers made visible on basemaps of reference, as much as on historical maps
Asymptotic stability of the Cauchy and Jensen functional equations
The aim of this note is to investigate the asymptotic stability behaviour of
the Cauchy and Jensen functional equations. Our main results show that if these
equations hold for large arguments with small error, then they are also valid
everywhere with a new error term which is a constant multiple of the original
error term. As consequences, we also obtain results of hyperstability character
for these two functional equations
VOICe THeRApy FOR LARyNgeAL HeMIpLegIA: THe ROLe OF TIMINg OF INITIATION OF THeRApy
Objective: Laryngeal hemiplegia, also known as vocal fold paralysis, causes severe communicative disability. Although voice therapy is commonly considered to be beneficial for improving the voice quality in several voice disorders, there are only a few papers that present scientific evidence of the effectiveness of voice therapy in treating the disabilities of laryngeal hemiplegia. The aim of this study was to evaluate the outcomes of voice therapy in patients with laryngeal hemiplegia and to evaluate the role of the time gap between onset of laryngeal hemiplegia and initiation of therapy. Design: A prospective study comparing subjects treated either within or more than 3 months after the onset of laryngeal hemiplegia. Subjects: The study involved 30 laryngeal patients with hemiplegia (16 males, 14 females, age range 15â80 years). Methods: All patients underwent videolaryngostroboscopy, maximum phonation time measurement, GIRBAS perceptual evaluation, Voice Handicap Index self-assessment and Multi-Dimensional Voice Program voice analysis before and after therapy. Results: In all tests, there were significant improvements in voice quality, both in the group treated within 3 months after the onset of laryngeal hemiplegia and in the group treated after this time. Conclusion: Voice therapy is effective in treating laryn geal hemiplegia even if treatment is delayed by more than 3 months from onset of laryngeal hemiplegia
Measurement of the Charge Collection Efficiency after Heavy Non-Uniform Irradiation in BaBar Silicon Detectors
We have investigated the depletion voltage changes, the leakage current
increase and the charge collection efficiency of a silicon microstrip detector
identical to those used in the inner layers of the BaBar Silicon Vertex Tracker
(SVT) after heavy non-uniform irradiation. A full SVT module with the front-end
electronics connected has been irradiated with a 0.9 GeV electron beam up to a
peak fluence of 3.5 x 10^14 e^-/cm^2, well beyond the level causing substrate
type inversion. We irradiated one of the two sensors composing the module with
a non-uniform profile with sigma=1.4 mm that simulates the conditions
encountered in the BaBar experiment by the modules intersecting the horizontal
machine plane. The position dependence of the charge collection properties and
the depletion voltage have been investigated in detail using a 1060 nm LED and
an innovative measuring technique based only on the digital output of the chip.Comment: 7 pages, 13 figures. Presented at the 2004 IEEE Nuclear Science

Microwave Assisted Synthesis, Characterization and Antibacterial Study of Some Novel Schiff's Bases, Thaizolidinone and Chalcone Compounds Derived from Mefenamic Acid
This work involves synthesis of some new heterocyclic compounds including thaizolidinone compounds. The new Schiff bases derived from mefenamic acid, which was synthesized by microwave irradiation of mefenamic acid with hydrazine hydrate in absolute ethanol and this amino compound condensation with different aromatic aldehydes in absolute ethanol. Thaizolidinone compounds were synthesized by cycloaddition reaction of mercapto acetic acid to imine group of Schiff bases in dry benzene. The new chalcone derivatives synthesized by the reaction aldehyde with their compounds. M.P., TLC, CHN, UV, FTIR and NMR spectroscopy has characterized all the synthesized compounds. The biological screening data of the synthesized compounds were also studied. Keywords: Schiff bases, thaizolidinone, chalcone, antibacterial
