    The current thesis intends to deepen the role of errors in the organizational field, viewed as an informational feedback which can contribute to the improvement of perform-ance, to the effective managing of the negative consequences of errors and highlighting new ways to organize and realize the work. The current dissertation tests this new conceptualiza-tion of error in the organizational settings, especially in the complex organizations. The first study, carried out on cross cultural Italian sample, explored the validity of the Error Culture scale. Results confirmed the validity, uniqueness, and generalizability of the EC scale and its influence on several outcomes, namely organizational performance, in-novativeness, errors made. The second study, conducted among hospital workers, tested an overall model in-cluding antecedents (trustworthiness) and a series of outcomes (organizational performance, innovativeness, errors made). The tested model confirmed the influence of trustworthiness on the error culture and the mediating role of error culture dimensions on the outcomes. The third study, among the safety and professional staff of the Italian civil aviation au-thority, deepened the error aversion culture model in a high complexity organization, enriching it with the inclusion of the leadership variables in the error aversion reduction. Results confirmed the hypothesized model regarding the influence of leadership styles and organizational culture dimensions on the aversion approach to individual errors. Practical implications and suggestions for future research are discussed for each of the three studies here presented

    In this work, a supercritical CO2 (SC-CO2) drying process for the formation of 3-D PVDF-HFP loaded scaffolds was tested. Experiments at pressures ranging between 150 and 250 bar and at temperatures ranging between 35 and 55?C were performed. The PVDF-HFP- acetone-ethanol solution at 15% w/w polymer was selected as the base case. The drug (amoxicillin) concentration was varied from 20 to 30% w/w with respect to PVDF-HFP. SC- CO2 drying process was confirmed to be a valid alternative to generate loaded structures; indeed, scaffolds characterized by nanometric networks (with mean pore diameter of about 300 nm) with a homogeneous drug distribution were obtained. Drug controlled release experiments were also performed and a quasi-zero order release kinetic was observed

    BACKGROUND: Silver-loaded hydroxyapatite nanoparticles were incorporated into poly(vinyl alcohol) (PVA) membranes obtained by supercritical CO2 (SC-CO2) assisted phase inversion. Ag3PO4 crystals of 2.2 ± 0.6 nm were dispersed in synthesized needle-like hydroxyapatite nanoparticles (20 × 65 nm) and were uniformly deposited on the internal surfaces of the PVA membranes. Operative conditions to produce membranes by SC-CO2, PVA concentration and the effect on membrane porosity and morphology were studied. RESULTS: Solutions at 20% w/w PVA produced membranes with cellular morphology and nanoporous walls, whereas 30% and 50% w/w solutions produced nanostructured membranes. Silver ions were released from PVA membranes mainly by diffusion according to the Peppas–Sahlin model. Membranes obtained at 20% w/w PVA showed a significant E. coli inhibition at an Ag concentration of 9 ppm, reaching the minimal inhibitory concentration (MIC) and improving the bactericidal activity of the nanoparticles. CONCLUSION: A concentration of Ag3PO4 crystals of about 22 ppm was calculated as being capable of completely destroying these bacteria, reaching the minimum bactericidal concentration (MBC)

    We present a theoretical vectorial model, validated by experimental measurements, describing the dependence of the Figure-9 laser output power, operating in continuous wave, on the coupling ratio of the directional coupler

    Supercritical Fluid Processing of Polymers

    No full text
    The use of supercritical fluids instead of organic solvents has attracted the interest of numerous researchers, due to the unique peculiarities of supercritical fluids which are characterized by solvent powers comparable to those of liquid organic solvents, diffusivity comparable to those of gaseous substances and quasi-zero surface tension [...
