I circoli di studio come dispositivo formativo e partecipativo nella promozione del turismo lento
No full textLa progettualità a livello europeo, nazionale e locale richiede una particolare attenzione nel coinvolgimento dei beneficiari sia in fase progettuale e sia in quella realizzativa. I circoli di studio si creano tra soggetti propositivi e motivati a confrontarsi, trovare soluzioni comuni e implementare le proprie idee; nascono in contesti locali ai quali poi vengono restituiti i risultati del lavoro. L’autore descrive l’esperienza dei circoli di studio nella programmazione transfrontaliera Italia-Slovenia, con particolare riferimento alla progettazione di territori e prodotti per un turismo lento: dalla promozione di prodotti agroalimentari tipici alla creazione di itinerari tematici
Planning for Proximity: Who, What, Where, When, Why (and How)
No full textProximity is a recurring concept in urban planning. Neighbourhood units (as defined by Clarence Perry), pedestrian pockets (proposed by Peter Calthorpe) and 15-minute cities (coined by Carlos Moreno) are just some of the definitions under which the idea of promoting places and lifestyles based on proximity emerges now and then in the academic, professional and public debate. Nonetheless, to imple-ment such an urban model through urban plans and policies, it is necessary to address several dimensions, deal with potentially tricky definitions and recognize the range of action of proximity. We intend to introduce them briefly, discussing the who, what, where, when (and how) of strategies intended to promote sustainable neighbourhoods, cities and regions through proximity
P Values and Statistical Significance
No full textThis resource, created by author Will G. Hopkins, defines what a p-value is, why .05 is significant, and when to use it. It also covers related topics such as one-tailed/two-tailed tests and hypothesis testing. Overall, this is a wonderful resource for students wanting to learn more about statistics, and more specially, significant testing
Preparation and quantitative study of gold nanoparticles forSERS biolabelling
No full textSERS probes based on gold nanoparticles – organic dyes nanocomposites are intensively investigated for in vitro and in vivo labelling or for bio-analytical applications. Their main advantages are: biocompatibility, enormous Raman scattering cross section, analysis at wavelengths in the transparency window of biological tissues, multiplex analysis based on the distinctive fingerprint of each label. Here we report about the preparation of AuNP obtained by laser ablation synthesis in solution (LASiS)1-5 and their functionalization with a series of Raman labels with different properties. The Raman scattering cross section and the minimum number of AuNP observable by Raman spectroscopy in different conditions were measured and used for quantitative comparison of the different labels. Optical microscopy and transmission electron microscopy were coupled to Raman analysis for this purpose. Calibration studies were applied to the quantification of cell uptake studies of nanoparticles. The results suggests that, in the best cases, about ten AuNP in the analysis volume are enough for practical application with common Raman spectrometers.

Genetic structure and fungicide sensitivity of Botrytis cinerea populations isolated from grapevine in northern Italy
No full textGrey mould, caused by Botrytis cinerea, is a disease severely affecting grape production in northern Italy. However, little information is available on the variability of B. cinerea populations associated with grapevine. The mode of reproduction, sensitivity to fungicides, and for the first time in Italy, the genetic structure of B. cinerea populations isolated from grapevine in a northern Italian region are reported. Botrytis cinerea isolates (317) were completely genotyped for six microsatellite loci and characterized for the presence of the transposable elements Boty and Flipper, for the mating type and for resistance to cyprodinil, fludioxonil, boscalid and fenhexamid. All the isolates were found to belong to B. cinerea Group II, indicating the absence of B. pseudocinerea in the investigated areas. The populations possess a high genotypic diversity, different frequencies of transposable elements and a mixed mode of reproduction. At a regional level, B. cinerea populations belong to a large and interconnected pathogen population that includes the major grape-growing districts. The populations were generally sensitive to fungicides, with a low proportion (8%) of isolates resistant to cyprodinil, fludioxonil and boscalid. A small genetic distance was found between B. cinerea populations. However, the populations geographically isolated from the others by a mountain range showed a small but statistically significant genetic differentiation and a different pattern of fungicide resistance. The results show that northern Italian B. cinerea populations possess a high evolutionary potential and adaptive capacity

Madrid 34: 156 (2010) Figs. 1A–F</p> <p>Sporophores sporocarpic, dispersed or in groups. Sporocarps stalked, sometimes sub-sessile, 0.25–0.8 mm in total height. Hypothallus inconspicuous. Stalk thick and black (0.1–0.3 mm long, 0.05–0.1 mm wide). Sporotheca 0.15– 0.4(–0.5) mm diam., dark brown to black, shining, with distinct pale lines of dehiscence that form a cross at the apex. Peridium double, outer layer of refuse material and the inner layer membranous, closely adhering together; dehiscence by fragmenting into polygonal plates leaving a basal calyculus at the union with the stalk. Spores free, dark brown in mass, olivaceous to olive brown by TL, with a thinner area by TL, subglobose, (14–)15–17 µm diam., smooth. By SEM the inner peridium is densely warted, the platelet margins are warted and paler with fewer inclusions; the epispore is verrucate with small dense warts and larger warts.</p> <p> <i>Material examined</i>: Holotypus.

The reason to include this normally stipitate species is that it dehisces into platelets, and sub-sessile sporocarps may be confused with sessile species. In addition it was not included in our study of the stalked <i>Licea</i> species (Wrigley de Basanta & Lado 2005). The edges of the platelets in this species have many small warts and less refuse material on the outer surface. The pale dehiscence lines were not as obvious in some sporocarps. Because of its habitat, with its host plant covered in winter and spring by snow, this is a nivicolous species and in fact it looks like a really minute <i>Lamproderma</i> under the stereoscope. The nivicolous habitat, clear silvery dehiscence lines and large spores easily distinguish this species. All these are different from its nearest stipitate species <i>L. pedicellata</i> (H. C. Gilbert) H. C. Gilbert. It is clearly distinguished from <i>L. eremophila</i> D. Wrigley, Lado & Estrada by the larger globose vs. angular spores. The excellent SEM images in the original publication (Moreno <i>et al.</i> 2010) obviated the need to repeat them.</p>Published as part of <i>Basanta, Diana Wrigley De, Mier, Carlos De & Lado, Carlos, 2023, A taxonomic revision of the species of Licea subg.

Flatness-based adaptive control of synchronous reluctance machines with output feedback
No full textThe present article proposes an adaptive neurofuzzy control method that is capable of compensating for model uncertainty and parametric changes of Synchronous Reluctance Machines (SRMs), as well as for lack of measurements for the SRMs state vector elements. First it is proven that the SRM's model is a differentially flat one. This means that all its state variables and its control inputs can be written as differential functions of key state variables which are the so-called flat outputs. Moreover, this implies that the flat output and its derivatives are linearly independent. By exploiting differential flatness properties it is shown that the 4-th order SRM model can be transformed into the linear canonical form. For the latter description, the new control inputs comprise unknown nonlinear functions which can be identified with the use of neurofuzzy approximators. The estimated dynamics of the electric machine is used by a feedback controller thus establishing an indirect adaptive control scheme. Moreover, to improve the robustness of the control loop a supplementary control term is computed using H-infinity control theory. Another problem that has to be dealt with comes from the inability to measure the complete state vector of the SRM. Thus, a state-observer is implemented in the control loop. The stability of the considered observer-based adaptive control approach is proven using Lyapunov analysis
