A Model Modulated Predictive Current Control Algorithm for the Synchronous Reluctance Motor
2022
This paper proposes a Model Modulated Predictive Control (M2PC) specifically developed for Synchronous Reluctance Motors (SynRM) drives and based on a purposely developed magnetic model taking into account both self- and cross-saturation. The proposed M2PC exploits the discrete-time version of the dynamic model to compute the current prediction and the resulting predicted current error. The built-in PWM modulator chooses the optimal pair of voltage space-vector to be applied by the inverter to minimize the current error. The magnetic model permits obtaining good dynamic performance in every working condition.
Long-term changes in business models in inland and mountainous areas for the promotion of sustainable food systems
2022
For the management of inland and mountainous areas to be economically viable, business activities in these environments must provide sufficient income for the local population without jeopardising the interests of future generations. In purely economic terms, the management of these areas requires that the production of such goods and services that constitute utility flows for an ecosystem and its local population be economically viable. This management must be able to provide an income for the local population; it cannot only support the costs inevitably incurred for the conservation and production of goods and services provided by the activities that take place in the mountain area. This …
Decadal variability and trends in extratropical Rossby wave packet amplitude, phase, and phase speed
2022
The ongoing global yet spatially inhomogeneous warming prompts the inspection of decadal variability in the extratropical upper-tropospheric circulation properties. This study provides observational evidence in this regard by utilizing reanalysis data to examine the past interannual-to-decadal variability and unveil trends in the probability distribution of Rossby wave packet (RWP) amplitude (E), phase (Φ), and phase speed (cp). First, a comparison between the NE Pacific and N Atlantic regions indicates that the 300 hPa E probability distribution exhibits a seasonally and regionally varying decadal variability. No apparent discrepancy arises between different reanalysis datasets, except fro…
Clinical Significance of Tie-2-Expressing Monocytes/Macrophages and Angiopoietins in the Progression of Ovarian Cancer—State-of-the-Art
2022
Tumour growth and metastasis are specific to advanced stages of epithelial ovarian cancer (EOC). Tumour angiogenesis is an essential part of these processes. It is responsible for providing tumours with nutrients, metabolites, and cytokines and facilitates tumour and immune cell relocation. Destabilised vasculature, a distinctive feature of tumours, is also responsible for compromising drug delivery into the bulk. Angiogenesis is a complex process that largely depends on how the tumour microenvironment (TME) is composed and how a specific organ is formed. There are contrary reports on whether Tie-2-expressing monocytes/macrophages (TEMs) reported as the proangiogenic population of monocytes…

Levelling Of I-Umlaut in Classical and Post-Classical Old Frisian Nouns
2022
The paper discusses and evaluates the extent of i-umlaut levelling in classical (ca. 1300–1400) and post-classical (ca.1400–1550) Old Frisian nouns. In terms of the methodology, the main goal of the analysis is to identify the quantitative relation between the incidence of i-umlauted and umlautless root vowels in the nominal declension paradigms. In order to understand and assess the process of levelling of i-umlaut in Old Frisian, three aspects that may have had an impact on the presence or absence of i-mutated vowels are taken into account, namely: the presence of the i-mutation trigger *-ī and *-j and *-i, the establishment of whether i-mutation is noticeable in the entire paradigm or it…
Somatic embryogenesis in Abies nebrodensis, an endangered Sicilian fir
2022
AbstractSomatic embryogenesis, as a promising biotechnological tool for many conifer trees, has never been applied for the Abies nebrodensis species. Although all the encouraging results previously obtained by the EU LIFE (European LIFE program) funded projects in over ten years, the critically endangered Sicilian fir remains alarmingly close to extinction. In this study, we reported the first protocol of somatic embryogenesis obtained from mature zygotic embryos of the Abies nebrodensis. Seeds from Abies adult trees with specific identification numbers (IN) were collected and full seeds were identified by X-ray. Different experiments were carried out for callus initiation, from both zygoti…
Promuovere le character skills per la transizione scuola-università: una ricerca- intervento internazionale
2022
In this contribution, we want to describe methodological assumptions with which to promote some character skills that must be trained in the students attending high school in view of the transition from school to university. These abilities are related to the person’s character, emotional and psychosocial aspects of the personality like flexibility, creativity, open-mindedness, resilience, decision-making skill and self-image. These skills significantly contribute to the construction of the 16-18-year-old student’s identity and support the development of his professional maturity during the school education period. High school teachers can contribute to this development by applying didactic…
Colour Terms in Five Linguistic Images of the World: The Semantic Perspective
2022
Social and cultural factors shape the linguistic perception of colour. At the same time, colour terms co-create the linguistic image of the world, which allows us to interpret reality and profile our statements and beliefs. This paper presents six basic colour terms: white, black, red, green, yellow, and blue (both as adjectives and as nouns) in the five different linguistic images of the world of the following languages: English, French, Italian, Polish, and Japanese. The methodological framework is based on cultural linguistics theory and the basis of semantics. The study explores denotative and connotative meanings of colour terms with their collocations. The data gathered from monolingu…
Di nuovo schiave. Donne e distopia (2007-2022)
2022
Il saggio analizza le peculiarità e le costanti della narrativa distopica scritta da donne in Italia lungo un arco di tempo che va dal 2007 al 2022. Riallacciandosi a una tradizione mainstream che in ambito anglosassone ha prodotto libri di successo come The Handmaid’s Tale di Margaret Atwood, le distopie italiane degli ultimi anni mettono in scena un futuro in cui a dominare è una società marcatamente patriarcale che esercita un controllo violento sul corpo e sull’identità femminili. Il cupo futuro raccontato da Laura Pugno, Nicoletta Vallorani, Maria Rosa Cutrufelli, Laura Pariani e altre scrittrici italiane nasce dall’amplificazione di stereotipi sessuali radicati nel presente e vuole es…
Age-associated changes in circulatory fatty acids: new insights on adults and long-lived individuals
2022
Long-lived individuals (LLIs) are considered an ideal model to study healthy human aging. Blood fatty acid (FA) profile of a cohort of LLIs (90–111 years old, n = 49) from Sicily was compared to adults (18–64 years old, n = 69) and older adults (65–89 years old, n = 54) from the same area. Genetic variants in key enzymes related to FA biosynthesis and metabolism were also genotyped to investigate a potential genetic predisposition in determining the FA profile. Gas chromatography was employed to determine the FA profile, and genotyping was performed using high-resolution melt (HRM) analysis. Blood levels of total polyunsaturated FA (PUFA) and total trans-FA decreased with age, while the lev…

Abstract Purpose of Review Boreal forests provide a wide range of ecosystem services that are important to society. The boreal biome is experiencing the highest rates of warming on the planet and increasing demand for forest products. Here, we review how changes in climate and its associated extreme events (e.g., windstorms) are putting at risk the capacity of these forests to continue providing ecosystem services. We further analyze the role of forest management to increase forest resilience to the combined effects of climate change and extreme events. Recent Findings Enhancing forest resilience recently gained a lot of interest from theoretical perspective. Yet, it remains unclear how to …
Perceived challenges living and integrating into Finnish society : A study among immigrants in Finland
2022
The number of immigrants living in Finland has significantly increased since the 1990s. It can be challenging to live and integrate into a new society. This study explores the challenges immigrants face living and integrating into Finnish society. Drawing on data collected from 103 immigrants living in Finland, this study shows that the challenges immigrants face integrating into Finnish society can be classified into four main categories: (1) language barrier, (2) discrimination in employment opportunities, (3) racism and inequality, and (4) fewer opportunities of integration. Implications and recommendations are briefly considered.
Vector Projection-based Sensorless Control of a SynRM Drive Including Self and Cross-Saturation
2022
This paper presents a sensorless technique for SynRM drives that is based on a vector projection method and takes into consideration the magnetic saturation of the motor, both the self and the cross-saturation. The proposed method is based on the dynamic equation of the SynRM including saturation, rewritten in integral form, and does not involve any high-frequency carrier injection. The technique has been tested in numerical simulation and experimentally on a suitably developed test set-up. Experimental results show a correct behavior of the sensorless SynRM drive, properly accomplishing speed transients in a wide speed range, including low speed, still maintaining a good accuracy in the sp…
Site-Coded Oral Squamous Cell Carcinoma Evaluation by Optical Coherence Tomography (OCT): A Descriptive Pilot Study
2022
Optical Coherence Tomography (OCT) is an emerging non-invasive method for oral diagnostics, proving to be a practicable device for epithelial and subepithelial evaluation. The potential validity of OCT in oral cancer assessment has been explored but, to date, there are very few investigations conducted with a systematic comparison between clinical/histological and OCT parameters, especially in strict reference to the anatomical site-codification of the oral mucosa. In this regard, our study performed a two-steps evaluation (in vivo OCT and histological investigations) of suspected OSCCs, progressively recruited, using as references the OCT images of the same site-coded healthy mucosa, to pr…
Industrial Symbiosis: A Mechanism to Guarantee the Implementation of Circular Economy Practices
2022
There is a growing concern regarding the scarcity of natural resources. The levels of resource exploitation generated by the current system of production and consumption has led the European Commission to develop a set of guidelines that aim to reduce the pressure on natural resources. The set of guidelines proposed by the European Union is based on the transformation of the current linear economic system into a circular system in which resources and materials remain in the production system for longer. However, for this change to take effect, practical measures are required. This paper presents an industrial symbiosis approach as a practical application of a circular economy model. The aim…
Combined effects of exploitation and environmental change on life history: a comparative analysis on Atlantic herring
2022
Abstract The consequences of fisheries-induced evolution on stock productivity and yield depend, to a large extent, on the general prospects for growth and survival. Here, we compare the selection pressures imposed by two distinct patterns of exploitation—principally targeting spawning or non-spawning aggregations—on age at maturity among 15 Canadian stocks of Atlantic herring (Clupea harengus) that have exhibited a consistent pattern of length-at-age responses to common large-scale environmental drivers since the 1960s. In accordance with expectations for maturity-dependent harvesting, the establishment of a spawner-targeted fishery in the southern Gulf of St. Lawrence coincided with a shi…

Effects of green tea catechins and exercise training on body composition parameters
2022
The impact of phytochemicals, as green tea catechins, on body composition measures has become a relevant topic as ongoing epidemiological evidence suggests their potential role in weight loss. Although catechins have been shown to modulate fat and energy metabolism, clinical effects of green tea consumption still remain controversial. Given the role played by physical exercise in weight management, it is important to determine whether the association of catechins and exercise is able to improve outcomes over and above the beneficial effects of exercise alone. Considering that scientific findings on this topic are not entirely consistent, aim of the present review was to assess the current s…

Salphen metal complexes as potential anticancer agents: interaction profile and selectivity studies toward the three G-quadruplex units in the KIT pr…
2022
DNA G-rich sequences can organize in four-stranded structures called G-quadruplexes (G4s). These motifs are enriched in significant sites within the human genomes, including telomeres and promoters of cancer related genes. For instance, KIT proto-oncogene promoter, associated with diverse cancers, contains three adjacent G4 units, namely Kit2, SP, and Kitt. Aiming at finding new and selective G-quadruplex binders, we have synthesized and characterized five non-charged metal complexes of Pt(II), Pd(II), Ni(II), Cu(II) and Zn(II) of a chlorine substituted Salphen ligand. The crystal structure of the Pt(II) and Pd(II) complexes was determined by XRPD. FRET measurements indicated that Pt(II) an…
The Role of the Coagulation System in Peripheral Arterial Disease: Interactions with the Arterial Wall and Its Vascular Microenvironment and Implicat…
2022
Peripheral artery disease (PAD) is a clinical manifestation of atherosclerotic disease with a large-scale impact on the economy and global health. Despite the role played by platelets in the process of atherogenesis being well recognized, evidence has been increasing on the contribution of the coagulation system to the atherosclerosis formation and PAD development, with important repercussions for the therapeutic approach. Histopathological analysis and some clinical studies conducted on atherosclerotic plaques testify to the existence of different types of plaques. Likely, the role of coagulation in each specific type of plaque can be an important determinant in the histopathological compo…

How Ionic Liquid Gels Work on the Removal of Bisphenol A from Wastewater
2022
The occurrence of emerging pollutants in water bodies is a pressing issue of modern society and identifying materials to remove them is the main target of current research. In this work, we prepared and characterized supramolecular gels of 1,3:2,4-dibenzylidene-d-sorbitol (DBS) in ionic liquids differing for the anion and the aliphatic or aromatic nature of the cation. We characterized our gels for their thermal stability and mechanical properties. We also found that all gels self-heal in 24 h after being cut by a razor blade. We then used our gels as sorbents to remove bisphenol A, an endocrine disruptor compound, from aqueous solutions. All gels adsorb BPA with high removal efficiencies, …
Enhancing Speed Loop PI Controllers with Adaptive Feed-forward Neural Networks: Application to Induction Motor Drives
2022
This paper proposes the idea to improve the performance of the speed loop PI controller by using feed-forward and adaptive control actions. Indeed, when the system to be controlled is required to track a rapidly changing reference frame, higher bandwidth is usually required, making the system more sensitive to noise and consequently less robust. In such cases, to achieve a better performance in reference tracking while keeping noise rejection capacity, one idea is to use a feed-forward controller, employed to enhance the required tracking, leaving the feedback action to stabilize the system and suppress higher frequency disturbance. As such, this paper analysis the classical PI based field …
Deformation Imaging by Strain in Chronic Heart Failure Over Sacubitril-Valsartan: A Multicenter Echocardiographic Registry
