The knowledge of the discriminating power of analytical techniques used for the differentiation of writing inks can be useful when interpreting results. Ultraviolet-visible (UV-VIS) spectrophotometry, thin layer chromatography (TLC), and diffuse reflectance Fourier transform infrared spectroscopy (FT-IR) were used to examine a population of 21 black and 12(More)
— In this paper, we consider the problem of steering complex dynamical systems among equilibria in their state space in efficient ways. Efficiency is considered as the possibility of compactly representing the (typically very large, or infinite) set of reachable equilibria and quickly computing plans to move among them. To this purpose, we consider the(More)
In this paper, we investigate the advantages and disadvantages of a proposed decentralized Air Traac Management A TM system, in which aircraft are allowed a larger degree of autonomy in deciding their route "free ight" instead of following prespeciied "sky freeways". A decentralized management s c heme is described, which incorporates a hybrid control(More)
Polyvinyl alcohol (PVA) electrospun nanofibers containing Ag nanoparticles (NPs) have been deposited on glass substrates. The aim of the work was to test the feasibility of this approach for the detection of biogenic amines by using either the Ag localized surface plasmon resonance quenching caused by the adsorption of amines on Ag NPs or by detecting the(More)
Nanocomposites based on isotactic polypropylene/ethylene propylene rubber (iPP/EPR) were prepared adding different amounts of montmorillonite and maleated polypropylene. The structure and morphology of the samples were characterized by small angle X-ray scattering, wide angle X-ray diffraction, electronic and optical microscopy and differential scanning(More)
Latex gloves are quite frequently employed by felons, when committing crimes, if they want to avoid shedding fingerprints or biological traces. Less forensic aware crime committers, though, may discard the gloves at the crime scene or nearby. If found and properly analyzed, these items may therefore provide useful information to investigators. An analytical(More)
Nanocomposites based on a copolymer of 1-butene and ethylene filled with montmorillonite (Cloisite 15A) were studied, obtaining for the first time crystallization from the melt directly into phase I. The polymorphism of the polymer and the dispersion of the filler in the matrix were investigated. The effect of the compatibilizer (PB-g-MA) on these(More)
Fiber evidence found on a suspect vehicle was the only useful trace to reconstruct the dynamics of the transportation of two corpses. Optical microscopy, UV-Vis microspectrophotometry and infrared analysis were employed to compare fibers recovered in the trunk of a car to those of the blankets composing the wrapping in which the victims had been hidden. A(More)
Agenesis of the bladder is a rare congenital anomaly, recorded most often in stillborn infants. Renal agenesis and other severe malformations are frequently associated. An apparent failure of the infraureteral tissue of the mesonephric duct to develop into trigone and proximal urethra seems to be the cause of this anomaly. We report a case of bladder(More)
