Definition of a sensory lexicon and development of sensory wheels of eighteen monovarietal Italian white wines
No full textBACKGROUND: Italy harbors one of the richest grapevine biodiversities worldwide, yet the sensory identity of wines from many native cultivars remains poorly defined despite their relevance on the market at regional, national, or international levels. This study provides a systematic sensory characterization of 18 Italian monovarietal white wines, analyzed across 246 commercial samples, including wines never investigated before by sensory analysis. Analysis of variance, hierarchical cluster analysis, and principal component analysis were applied to Rate-All-That-Apply (RATA) data performed by trained panelists to define a lexicon and identify the sensory attributes characterizing and discriminating the 18 wine types. RESULTS: A statistically based lexicon comprising 29 olfactory and seven taste/mouthfeel descriptors was defined. Multivariate statistics showed that the 18 monovarietal wine types belong to four main olfactory dimensions, labeled as fruity–balsamic, thiolic–mineral, floral–sweet, and toasty–dried. A three-dimensional space was defined along the four olfactory directions. Müller Thurgau, Gewürztraminer, Albana, and Falanghina emerged as the most representative wines in these directions, outlining the vertices of a spatial framework within and around which the other wines are distributed. Sensory wheels representing structured visual synthesis of the most relevant attributes (odor, taste, mouthfeel) were developed as ‘identity models’, providing systematic tools for defining wines' varietal typicality. CONCLUSION: Results are relevant for enologists and wine sellers as standardized reference sensory models for production and communication, as benchmarks for PDO/PGI quality control and disciplinary improvement, for researchers to advance modeling of wine sensory quality through sensometabolomic wine studies. Results also support the international recognition and valorization of Italian grapevine biodiversity according to Agenda 2030 sustainable development goals

No full textSignificant Impact of Schmallenberg Virus in Three Ruminant Farms: A Laboratory Experience
No full textSchmallenberg virus (SBV) is endemic in Europe and other parts of the world and represents an underestimated and under-diagnosed cause of abortion and economic losses for livestock farms. In the present study, we evaluated SBV’s impact on threeruminant farms, in particular, two dairy cattle farms with reproductive problems (including abortions, stillbirths, and mal-formations) and a clinically healthy bufalo farm involved in oocyte collection through ovum pick-up (OPU) for in vitro embryoproduction and commercial sale. All sampled animals were subjected to serological assays against the main infectious agentsresponsible for reproductive disorders in ruminants: SBV, bluetongue virus (BTV), Coxiella burnetii (C. burnetii), bovineherpesvirus type 1 (BHV-1), bovine viral diarrhea virus (BVDV), and Brucella abortus (B. abortus). Te frst herd with re-productive disorders had a high (78%) seroprevalence for SBV (considered to be the cause of reproductive problems), while theprevalence observed for BTV was modest (16.7%). Although free from B. abortus, the second dairy farm had only a few animalsthat were seropositive for C. burnetii and BTV (1/22 and 2/22, respectively), but a prevalence of 72.7% for SBV. Te bufalo farmhad several animals seropositive for C. burnetii (9/52), BTV (10/52), and SBV (12/52). Almost half of the sampled animals wereexposed to at least one pathogen (26/52). Seropositive animals were excluded from oocyte collection in compliance withregulatory health requirements. One month later, seronegative animals were retested, revealing the seroconversion of anotheranimal for SBV, which was also excluded. Tis study has described, through seroprevalence testing, the direct impact of SBV onlivestock (clinical impact) and how it afects the selection of animals for the trade of genetic material (indirect impact

Poroelasticity in the presence of active fluids
No full textThis work presents a model for characterizing porous, deformable media embedded with magnetorheological fluids (MRFs). These active fluids exhibit tunable mechanical and rheological properties that can be controlled through the application of a magnetic field, which induces a phase transition from a liquid to a solid-like state. This transition profoundly affects both stress transmission and fluid flow within the composite, leading to a behaviour governed by a well-defined threshold that depends on the ratio between the pore size and the characteristic size of clusters of magnetic particles, and can be triggered by adjusting the magnetic field intensity. These effects were confirmed through an experimental campaign conducted on a prototype composite obtained by imbibing a selected MRF into commercial sponges. To design and optimize this new class of materials, a linear poroelastic formulation is proposed and validated through comparison with experimental results. The constitutive relationships, i.e. overall elastic constitutive tensor and permeability, of the model are updated from phenomenological observations, exploiting the experimental data obtained for both the pure fluid and the composite material. The findings demonstrate that the proposed simplified formulation is sufficiently robust to predict and optimize the behaviour of porous media containing MRFs. Such materials hold significant promise for a wide range of engineering applications, including adaptive exosuits for human tissue and joint rehabilitation, as well as innovative structural systems
A stage for the sovereignty. Culture and Power in Mediaeval Age, in The Routledge Handbook of the History of Naples since the Late Middle Ages
No full textThe article explores the history of culture in Naples in 4 moments: 1) the Ducal and Byzantine period, between the Late Antique and Early Medieval ages (VI-XI cent.); 2) the Norman-Swabian period (XII-XIII cent.), in which Naples becomes the first state university in history, founded by Emperor Frederick II Hohenstaufen; 3) the Angevin age (XIII-XV cent.), in which the city (especially with Charles II of Anjou) assumes the characters of the capital of the Kingdom of southern Italy and sees the development of literature in the Italian vernacular (with the presence of Giovanni Boccaccio); 4) the Aragonese age (second half of the XV cent.) in which the city becomes the capital of the “Catalan-Aragonese empire” and the propulsive center of an innovative monarchical and Mediterranean Renaissance
