Reduction of cogging force in linear generators for wave energy harvesting
2022
Due to huge energy potential of sea waves, many technologies have been proposed in the last few years. Some concepts have been developed and sometimes also tested in the open sea. Some prototypes use linear generators to directly convert the vertical motion of buoys into electrical energy. This solution minimizes the numbers of energy conversion steps, increasing the energy efficiency. At the same time, the limited numbers of components could also increase the reliability of the wave energy converter. For this reason, the development of linear generators is considered with great interest. This paper investigated the cogging force, a magnetic force due to the interaction between the magnets …

Fake news on Facebook and their impact on supply chain disruption during COVID-19
2022
AbstractSocial media (SM) fake news has become a serious concern especially during COVID-19. In this study, we develop a research model to investigate to what extent SM fake news contributes to supply chain disruption (SCD), and what are the different SM affordances that contribute to SM fake news. To test the derived hypotheses with survey data, we have applied partial least square based structural equation modelling (PLS-SEM) technique. Further, to identify how different configurations of SC resilience (SCR) capabilities reduce SCD, we have used fuzzy set qualitative comparative analysis (fsQCA). The results show that SM affordances lead to fake news, which increases consumer panic buying…
Human Duties and Rights in an Intercultural Perspective
2022
This paper reflects on the possibility of opening new ways of revaluing the role of human responsibilities and duties by establishing a relationship with rights that goes further than a simple correspondence between correlative terms. Approaching the interdependence between the language of rights and the language of duties from an intercultural perspective helps achieve an increasingly broader, but necessarily more complex, consensus. This analysis goes back to the Universal Declaration of Human Rights, which left duties in the background but showed the incipient presence of an intercultural purpose thanks to the work of UNESCO. The final part of the paper is devoted to those international …
Squaring Nemesis: Alexander’s Dream, the Oracle, and the Foundation of the New Smyrna
2022
In the 7th book of the Periegesis, Pausanias devotes a long digression to the Ionian migration in Asia Minor, focusing briefly on the story of Smyrna, whose territory originally belonged to the Aeolian settlers and was then occupied, at the beginning of the 7th century, by the Ionians from nearby Colophon. The arrival of Alexander the Great in the region marked the beginning of a new phase for Smyrna. Pausanias reports that the Macedonian king, on his way back from a hunting expedition on Mount Pagos, arrived at the sanctuary of the Nemeseis. There, the divinities appeared to him in a dream telling him to find a city and to bring there the inhabitants of the older polis. The Smyrnaeans then…
Plant products as biocides for conservation of cultural asset sustainable for human and environmental health
2022
In the last decades plants products are increasingly used also in defining innovative procedures for sustainable conservation of cultural heritage. Particularly, essential oils or hydro-alcoholic extracts have been fruitful applied to contrast microbial colonization on organic and inorganic artworks or insect infestation (Anobidae) having regard to the repellent action.
 In this paper, extracts from Asteraceae and Lamiaceae plant families are utilized to counteract widespread microbial colonization (bacteria, cyanobacteria, fungi) due to their antimicrobial activity. In order to define the adequate concentration correlating it to microbial species detected, the antimicrobial activity o…
Associations between teacher quality, instructional quality and student reading outcomes in Nordic PIRLS 2016 data
2022
AbstractProgress in International Reading Literacy Study (PIRLS) focuses on the reading proficiency of students mostly in the fourth year of schooling. A wide selection of studies has shown that family background and early literacy activities at home have substantial associations with student achievement in reading literacy. However, research focusing on teacher qualities and teaching processes is inadequate. In this study, we focus on associations of teacher quality (formal qualifications and professional identity) and instructional quality (classroom management, cognitive activation and teacher support) with cognitive and affective-motivational student outcomes (variables Reading Achievem…

Green Extraction of Polyphenols from Waste Bentonite to Produce Functional Antioxidant Excipients for Cosmetic and Pharmaceutical Purposes: A Waste-t…
2022
In an ever-growing perspective of circular economy, the development of conscious, sustainable and environmental-friendly strategies to recycle the waste products is the key point. The scope of this work was to validate the waste bentonite from the grape processing industries as a precious matrix to extract polyphenols by applying a waste-to-market approach aimed at producing novel functional excipients. The waste bentonite was recovered after the fining process and opportunely pre-treated. Subsequently, both the freeze dried and the so-called “wet” bentonites were subjected to maceration. PEG200 and Propylene Glycol were selected as solvents due to their ability to dissolve poly…
Mapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000–2018
2022
Abstract Background Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions.

2022
Históricamente, la Fonética-Fonología es una disciplina que no solo ha estado al servicio de la especulación teórica, sino que también ha estado ligada a la formación de maestros y a la intervención logopédica. En concreto, en este estudio, se trata de describir cómo los avances en el método oral destinado a la población sordomuda en el siglo XIX supusieron también avances en la teoría fonológica. Con este objetivo, en primer lugar, se realiza una breve descripción de las obras clásicas grecolatinas, que suponen el punto de arranque de la historia de la Fonética-Fonología. En segundo lugar, se ofrece un breve resumen de las principales aportaciones fonéticas/fonológicas de los distintos gra…
Inferring directionality of coupled dynamical systems using Gaussian process priors: Application on neurovascular systems
2022
Dynamical system theory has recently shown promise for uncovering causality and directionality in complex systems, particularly using the method of convergent cross mapping (CCM). In spite of its success in the literature, the presence of process noise raises concern about CCM's ability to uncover coupling direction. Furthermore, CCM's capacity to detect indirect causal links may be challenged in simulated unidrectionally coupled Rossler-Lorenz systems. To overcome these limitations, we propose a method that places a Gaussian process prior on a cross mapping function (named GP-CCM) to impose constraints on local state space neighborhood comparisons. Bayesian posterior likelihood and…
Through Thick and Thin : The Meaning of Dementia for the Intimacy of Ageing Couples
2022
As the population ages, the number of people with dementia increases. An emerging body of research is focusing on living with dementia and understanding the experience of caring and the care burden. There is much less research on the meaning of dementia from the perspective of an older couple’s spousal relationship and related intimacy. This qualitative study explores the meanings of emotional and physical intimacy and the changes brought by dementia in the couplehood of persons with dementia and their spousal carers. The data comprise semi-structured interviews with 35 persons. The interviews were analysed using inductive qualitative content analysis. Four themes describing the meanings of…

SleepXAI: An explainable deep learning approach for multi-class sleep stage identification
2022
AbstractExtensive research has been conducted on the automatic classification of sleep stages utilizing deep neural networks and other neurophysiological markers. However, for sleep specialists to employ models as an assistive solution, it is necessary to comprehend how the models arrive at a particular outcome, necessitating the explainability of these models. This work proposes an explainable unified CNN-CRF approach (SleepXAI) for multi-class sleep stage classification designed explicitly for univariate time-series signals using modified gradient-weighted class activation mapping (Grad-CAM). The proposed approach significantly increases the overall accuracy of sleep stage classification …

Introduction: Influenza is an acute respiratory infection that usually causes a short-term and self-limiting illness. However, in high-risk populations, this can lead to several complications, with an increase in mortality. Aside from the well-known extrapulmonary complications, several studies have investigated the relationship between influenza and acute cardio and cerebrovascular events. Reviews of the thromboembolic complications associated with influenza are lacking. Objectives: the study aims to conduct a scoping review to analyze the epidemiological and clinical characteristics of patients suffering from influenza and thromboembolic complications. Materials and methods: A computerize…
Recovering Sicilian Silk Heritage through Digital Technologies: The Case of Piraino’s Collection
2022
Textile conservation has given rise to small and medium-sized museums, usually with scarce resources. In Sicily, the little evidence that remains of silk production and opulent imports by the rich and powerful local aristocracy is kept in museums, parishes, and other cultural institutions. The documentation, dissemination, and enhancement of such a fragile heritage is today possible by means of technological tools that provide novel means to preserve, analyze, and exploit digital information. In this paper, we present some outcomes of the SILKNOW project, a project that applies computing research to the needs of diverse users (museums, educational institutions, the tourism industry, creativ…
The Benign Side of the Abdominal Wall: A Pictorial Review of Non-Neoplastic Diseases.
2022
The abdominal wall is the location of a wide spectrum of pathological conditions, from benign to malignant ones. Imaging is often recommended for the evaluation of known palpable abdominal masses. However, abdominal wall pathologies are often incidentally discovered and represent a clinical and diagnostic challenge. Knowledge of the possible etiologies and complications, combined with clinical history and laboratory findings, is crucial for the correct management of these conditions. Specific imaging clues can help the radiologist narrow the differential diagnosis and distinguish between malignant and benign processes. In this pictorial review, we will focus on the non-neoplastic benign mas…
Assessment and strengthening of reinforced concrete bridges with half-joint deterioration
2022
Existing Niagara-type concrete cantilever bridges, which in Italy are called Gerber bridges, suffer from degradation due to reinforcement corrosion and a consequent reduced load-bearing capacity. The assessment of these structures is therefore an important part of the procedures for analyzing the state of existing bridges and any interventions required for their retrofitting. In particular, safety against failure of the half-joint must be evaluated with respect to the behavior of the entire bridge and its state of conservation, determining what the conditions are that lead to failure, in terms of loads, state of stress, and possibly cracking state. This evaluation has to be carried out cons…
Hamstring Graft Preparation for ACL Reconstruction
2022
Anterior cruciate ligament (ACL) reconstruction represents one of the most common procedures in orthopedic surgery. It usually involves the harvest of both gracilis and semitendinosus tendons from the ipsilateral knee. Different methods of hamstring graft preparation have been proposed in recent years, to create an adequate graft diameter reducing morbidity linked to gracilis tendon harvesting procedure. More recently, the use of only 1 of the tendons (semitendinosus) in a tripled or quadrupled arrangement has been described, especially in an all-inside type of reconstruction. Having a thicker tendon with a quadrupled semitendinosus (ST), instead of double gracilis and ST enables to have a …
Anemia in non-celiac wheat sensitivity: Prevalence and associated clinical and laboratory features.
2022
Background: Patients suffering from non-celiac wheat sensitivity (NCWS) frequently report extra- intestinal symptoms, such as anemia. Aims: We investigated the prevalence and associated clinical features of anemia in NCWS patients. Methods: Data from 244 NCWS patients, diagnosed by double-blind placebo-controlled wheat challenge, were retrospectively reviewed and compared with 2 control groups (celiac disease (CD) and irritable bowel syndrome (IBS)). Furthermore, 31 NCWS anemic patients were prospectively re-evaluated after at least 12 months on the “strict”wheat-free diet (WFD). Results: Anemia prevalence in NCWS patients was 34.8% (mean hemoglobin 10.4 ±1.4 g/dl), significantly higher tha…
IL-1 Superfamily Member (IL-1A, IL-1B and IL-18) Genetic Variants Influence Susceptibility and Clinical Course of Mediterranean Spotter Fever
2022
Mediterranean Spotted Fever (MSF) is one of the most common spotted fever Rickettsioses. Most cases of MSF follow a benign course, with a minority of cases being fatal. The severity of the infection depends on bacterial virulence, dose and host factors such as effective immune response and genetic background. Herein, we reported data on typing by competitive allele-specific PCR of functionally relevant polymorphisms of genes coding for MyD88 adapter-like (Mal/TIRAP) protein (rs8177374), interleukin(IL)-1 cluster (IL-1A rs1800587, IL-1B rs16944 and rs1143634) and IL-18 (rs187238), which might be crucial for an efficient immune response. The results enlighten the role that IL-1 gene cluster v…

Kotiin jääneiden lasten huomiointi päiväkodeissa kevään 2020 covid-19-poikkeusolojen aikana
2022
Suomessa asetettiin keväällä 2020 covid-19-pandemiasta johtuen poikkeusolot, jolloin kunnat vapautettiin varhaiskasvatuksen järjestämisvastuusta ja suositeltiin lasten jäämistä kotiin varhaiskasvatuksesta, jos se perheille oli mahdollista. Enemmistö lapsista jäi kotiin ja heille järjestettävästä varhaiskasvatustoiminnasta tehtiin ratkaisuja paikallisesti. Tämä on saattanut asettaa lapsia eriarvoiseen asemaan. Tutkimuksessamme tarkastelemme, kuinka päiväkodit huomioivat poikkeusolojen aikana päiväkodista kotiin jääneitä lapsia sekä mitkä lapseen tai perheeseen liittyvät tai kontekstuaaliset tekijät selittivät huomioinnin todennäköisyyttä. Analysoimme 5-6-vuotiaiden lasten vanhemmilta syksyll…
Millainen johtaminen tuki peruskoulujen henkilöstön työhyvinvointia covid-19-pandemiasta johtuneen etäkoulun aikana?
2022
Henkilökunnan hyvinvointi on yhteydessä johtamiseen, mutta koulukontekstissa johtajuuden merkitystä henkilökunnan hyvinvoinnille (ja sitä kautta oppilaiden hyvinvoinnille) tunnetaan heikosti. Tässä tutkimuksessa keskitymme kolmeen johtajuusominaisuuteen, jotka kirjallisuuden perusteella näyttäytyvät potentiaalisina hyvinvointijohtamisen tekijöinä koulukontekstissa: palveleva johtaminen, henkilöstön hyvinvoinnista huolehtiminen ja jaettu vastuu. Tutkimme, ovatko nämä tammi-helmikuussa 2020 (n=437, 48 koulua) ennen etäkoulua Keski-Suomen koulujen henkilökunnan arvioimat johtajuustekijät yhteydessä heti etäkoulun päättyessä toukokuussa 2020 (n=270, 27 koulua) arvioituun henkilöstön hyvinvointi…

Combinatorial Vacuum-Deposition of Wide Bandgap Perovskite Films and Solar Cells
2022
The development of vacuum-deposited perovskite materials and devices is partially slowed down by the minor research effort in this direction, due to the high cost of the required research tools. But there is also another factor, thermal co-deposition in high vacuum involves the simultaneous sublimation of several precursors with an overall deposition rate in the range of few Å s−1 . This leads to a deposition time of hours with only a single set of process parameters per batch, hence to a long timeframe to optimize even a single perovskite composition. Here we report the combinatorial vacuum deposition of wide bandgap perovskites using 4 sources and a non-rotating sample holder. By using sm…

Comparaisons intensives en français médiéval : les noms d’animaux comme deuxième terme de la comparaison
2022
Nous étudions les comparaisons intensives du français médiéval (ancien et moyen français) dont le deuxième terme correspond à un nom d’animal (p. ex. ‘hardi comme un lion’, ‘humble comme un mouton’, ‘battre qqn comme un âne’). Nous envisageons successivement (en suivant une typologie zoologique d’inspiration médiévale) les noms génériques d’animaux, les noms de quadrupèdes (sauvages et domestiques), les oiseaux, les poissons et la vermine. Nous donnons de nombreux exemples issus de sources variées. Nous avons identifié une soixantaine de bases adjectivales et une quarantaine de bases verbales distinctes pour le type de comparaisons considérées. L’étude de ces comparaisons (présentant différ…
