No full textStylistic design engineering (SDE) for an innovative green vehicle following QFD and triz applications
No full textWith this article, we intend to set the first strategic phase of the product development process, that is to say the one related to the conceptual project. In particular, this work refers to the installation of the project of an innovative, green, sustainable means of transport based on renewable energy, to move to the center of medium and large cities. The discussion presented presents a series of cutting-edge methods, in series of logical use, in order to make both strategic and technical decisions. Among the inputs of the methods, we will have an analysis of customer needs, competitive analysis, a series of technological objectives (or performances) as a result of the work in progress. In particular, we will first use the quality distribution method (QFD), then the method of analyzing competition through Benchmarking to identify the quantitative requirements that will give us the opportunity to create an innovative product, enhanced by a Top-Flop analysis to determine the number of requirements of the best product on the market, which will be the limit to be overcome to embody innovation in a new project. As for the QFD, the input values are the customer's requirements, obtained with the "Six questions" method; then applying an interrelationship of the QFD matrix, the outputs of the method described above were obtained, representing the classification of all the various urban transports, classified according to user preferences. The application of the competition-oriented method of competition analysis through the use of Benchmarking is applied after the QFD. The inputs are the quantitative specifications, that is the performance, of all the hoverboard models of all the brands on the market. The output, however, is a comparison graph that contains all the performance values for each model. Other inputs will be table data, other outputs, values (or ranges of values) for each performance, so as to obtain a technical specification with quantitative objectives to obtain an innovative product

Congenital melanotic macules of the tongue. A case report and brief review of the literature.
No full textCongenital melanotic macules of the tongue (CMMT) are a rare and benign condition that is probably underestimated. We report the case of an African infant with multiple congenital hyperpigmented macules of the tongue. To avoid a difficult-to-perform procedure such as a tongue biopsy, focused clinical monitoring was performed every 3 months for 30 months to detect significant changes. A clinical diagnosis of CMMT was made in the absence of concomitant systemic diseases using the clinical findings, the location on the tongue, the negative family history for melanoma, and the absence of drugs and toxic exposure. Clinical follow-up may be sufficient to monitor CMMT rather than performing a tongue biopsy
La farmacoterapia delle malattie cutanee allergiche in gravidanza
No full textBackground. The treatment of allergic skin diseases during pregnancy is extremely difficult due to a lack of literature data regarding both topical and systemic drugs suitable for these pathologies. In practice we resort to the few drugs known as 'safe' during pregnancy or to 'old' harmless remedies, according to suggestions contained in clinical pharmacology texts. There are two problems to cope with: pharmacological therapy during pregnancy and pregnancy during pharmacological therapy, a fairly common event considering the high incidence of allergic diseases in young women. Methods. From the literature data, different categories of drugs such as corticosteroids, antihistamines and DSCG for topical and systemic use are listed. Results. Topical steroids can be administered for long periods and during the first three months of pregnancy provided their effects on the axis of the hypothalamus-pituitary-suprarenal gland are born in mind. Conclusions. Systemic antihistamines should only be ..
Gas Solubility, Diffusivity, Permeability, and Selectivity in Mixed Matrix Membranes Based on PIM-1 and Fumed Silica
No full textThe effects of adding fumed silica (FS) nanoparticles on the gas permeability, solubility, diffusivity and selectivity of a polymer of intrinsic microporosity (PIM-1) are modeled considering the density of the composite matrix as the key input information. PIM-1 is treated as a homogeneous glassy polymer endowed with a specific free volume that increases with the amount of nanoparticles loaded, as indicated by the experimental values of mixed matrix density. The solubility isotherms of H2, He, O2, N2, CH4 and CO2 in matrices of PIM-1 with different FS loadings are calculated with the Nonequilibrium Lattice Fluid (NELF) model. The gas diffusivity and permeability variation due to FS addition are related to the fractional free volume of the polymer phase according to the semiempirical free volume theory equation. Remarkably, the coefficient amplifying the free volume effect increases with the molecular size of the gas, expressed by the van der Waals volume, thus allowing to estimate the transport properties of gases not investigated experimentally, such as methane. The behavior inspected differs from the one observed in Mixed Matrix Membranes (MMM) formed by PIM-1 and porous selective fillers, that show higher selectivity towards smaller penetrants than the pure polymer, because the effect of silica nanoparticles is only represented by an enhancement of the large free volume domains. The model allows to estimate the ideal selectivity together with its solubility and diffusivity contributions, at various FS contents, for several gas pairs (O2/N2, CO2/N2, CO2/CH4, CO2/H2), which are then compared to the experimental trends available
Sviluppo locale e turismo culturale. La Tabula Peutingeriana: un punto di partenza
No full textLa crescente richiesta di turismo culturale da parte del pubblico va di pari passo con la crisi del tradizionale turismo balneare. Il progetto europeo ROMIT che coinvolge diverse università dell'Unione europea si propone di progettare itinerari fondati sulla presenza di vestigia romane nelle diverse regioni. Nel caso dell'Emilia Romagna gli itinerari sono numerosi e possono essere inquadrati e in qualche modo unificati all'interno della rete stradale individuabile nella Tabula Peutingeriana, l'unica carta geografica romana giunta fino a noi, sia pure attraverso una copia del XII secolo. Le caratteristiche peculiari di questa rappresentazione e le sue vicende attraverso i secoli, come anche le riproduzioni a stampa che ne sono state realizzate nel passato, sono degne di interesse e di approfondimento anche ai fini della fruizione da parte di un pubblico colto, anche se non specializzato, come quello dei turisti
