Dead-time impact on the harmonic distortion and conversion efficiency in a three-phase five-level Cascaded H-Bridge inverter: mathematical formulatio…
2023
To avoid leg short-circuit in inverters, dead time must be introduced on leg gate signals. Dead time affects the inverter output voltage fundamental harmonic amplitude, voltage harmonic distortion and inverter efficiency by introducing additional voltage drops. In this regard, dead time effects have been widely investigated for traditional two-level three-phase voltage source inverters in the literature but not extensively for multilevel topology structures. This paper provides a detailed analysis of dead time impact on the harmonic distortion and efficiency of Cascaded H-Bridges Multilevel Inverters (CHBMIs). For this purpose, a general mathematical formulation to determine voltage drop du…

2023
Denne studien søker innsikt i to barnehagers arbeid med barn det er knyttet bekymring til, i en kommune i Agder ved bruk av BTI-modellen, som står for «Bedre Tverrfaglig Innsats». BTI-modellen er en samhandlingsmodell som kom som et tilskudd til Norge i 2012, med ønske om å forbedre den tverrfaglige samordningen i kommuner det var særlig behov for utbedring av tverrfaglig samarbeid. I tillegg er hensikten med modellen å fremme tidlig innsats og brukermedvirkning i tjenesters arbeid med både gravide, barn, unge og foreldre det er knyttet bekymring til. I Agder fylkeskommune kom BTI-modellen i 2017, som et tilskudd som del av et nasjonalt program for folkehelsearbeid i kommunene (folkehelsepr…
Mecanismos Bioquímicos y Moleculares de la Neurodegeneración en la Enfermedad de Alzheimer
2023
La enfermedad de Alzheimer se caracteriza por la presencia de placas amiloideas, hiperfosforilación de la proteína TAU e incremento de la inflamación cerebral. El uso de modelos animales de experimentación, como APP/PS1 (proteína precursora de amiloide/presenilina 1), permite observar los cambios producidos tanto a nivel de bioquímico como de biología molecular. Las células encargadas de intervenir en el proceso inflamatorio cerebral son los astrocitos y la microglía. Los resultados de esta tesis nos indican que los cambios en las quimiocinas y los receptores de quimiocinas son importantes debido a la implicación que podrían tener en la inflamación relacionada con la enfermedad de Alzheimer…
Informal learning and wellbeing outcomes of gameplay and their associations with gameplay motivation
2023
Educational functions of digital games are often seen only in the light of the serious and purposeful activities that aim for learning outcomes, in contrast with noneducational games that are designed for entertainment. The focus of this paper is in studying players’ learning outcomes from playing non-educational games, and how these relate to wellbeing outcomes of playing, and gaming motivation. The data for this study was collected via a survey (N = 1,202) in the United Kingdom and the United States. The survey respondents answered the question regarding what players perceive they have learnt by playing digital games. A generic datadriven qualitative content analysis of the responses to t…
The Yuck Factor : Reiterating Insect-Eating (and Otherness) Through Disgust
2023
In this chapter, representing critical cultural studies and visual studies, I consider insect-eating’s media portrayals by employing discourse analysis, semiology, and visual analysis methods. I conduct a qualitative analysis of the textual and visual elements in selected media portrayals of entomophagy. The focus is on Anglophone media iterations between 2013-2020, discovered online through Google searches Spring 2019 and Spring 2021. I am particularly interested in disgust’s role in mediating entomophagy to mass audiences. Through theories of this visceral emotion, I discuss the main ways historical Western representations of revulsion against insects and insect-eating resurface despite t…
Projekty citizen science jako metoda wzmocnienia świadomości społecznej o problemie antybiotykooporności
2023
Problem antybiotykooporności jest według WHO jednym z najbardziej donośnych zagrożeń XXI wieku. Z roku na rok umiera coraz więcej osób na skutek zakażenia bakterią, która jest oporna na znane antybiotyki. Aby zapobiegać rozwojowi antybiotykooporności konieczny jest wzrost świadomości społecznej o niekorzystnych skutkach nadużywania i niewłaściwego stosowania antybiotyków. W tym celu prowadzone są liczne kampanie i akcje społeczne. Aby dotrzeć z tymi informacjami także do młodzieży realizowane są projekty citizen science, w które zaangażowani są studenci i uczniowie. W artykule przedstawimy cele i zakres projektów citizen science oraz service learning podejmowanych w celu edukacji społeczeńs…

MAUREL Raphaël (dir.), Nouveaux regards sur le droit européen des investissements, Dijon, LexisNexis, coll. du CREDIMI, 2023, 492 p.
2023
Les relations entre droit européen et droit des investissements ont donné lieu, ces dernières années, à des réflexions sur l’émergence d’un droit régional spécial, qui se caractériserait par une « approche européenne » des investissements. On pense par exemple à la volonté de « verdissement » des investissements, ou encore à la prise en compte des contestations de la société civile quant aux modes de règlement des différends relatifs aux investissements. Le thème est particulièrement d’actualité depuis l’arrêt Achmea en 2018, qui a constitué une petite révolution du droit des investissements sans que soient réglé l’ensemble des questions juridiques qu’il soulève – lui et ses suites. Cette d…
Measurement of inclusive and leading subjet fragmentation in pp and Pb–Pb collisions at √sNN = 5.02 TeV
2023
This article presents new measurements of the fragmentation properties of jets in both proton–proton (pp) and heavy-ion collisions with the ALICE experiment at the Large Hadron Collider (LHC). We report distributions of the fraction zr of transverse momentum carried by subjets of radius r within jets of radius R. Charged-particle jets are reconstructed at midrapidity using the anti-kT algorithm with jet radius R = 0.4, and subjets are reconstructed by reclustering the jet constituents using the anti-kT algorithm with radii r = 0.1 and r = 0.2. In proton–proton collisions, we measure both the inclusive and leading subjet distributions. We compare these measurements to perturbative calculatio…
Measurements of second-harmonic Fourier coefficients from azimuthal anisotropies in p+p, p+Au, d+Au, and 3He+Au collisions at √sNN = 200 GeV
2023
Recently, the PHENIX Collaboration has published second- and third-harmonic Fourier coefficients v2 and v3 for midrapidity (|η|<0.35) charged hadrons in 0%–5% central p+Au, d+Au, and 3He+Au collisions at √sNN=200 GeV, utilizing three sets of two-particle correlations for two detector combinations with different pseudorapidity acceptance [Acharya et al., Phys. Rev. C 105, 024901 (2022)]. This paper extends these measurements of v2 to all centralities in p+Au, d+Au, and 3He+Au collisions, as well as p+p collisions, as a function of transverse momentum (pT) and event multiplicity. The kinematic dependence of v2 is quantified as the ratio R of v2 between the two detector combinations as a funct…
L'architettura ed il pianeta malato
2023
Global warming and building activity are strictly tied.This should lead architects to reconsider their design attitudes. Yet this does not happen if not as mere technologal answer. The reasons for this inadequacy fall within an ample process tht dates back to Cartesio and that has been delineated by Husserl and existantialist thinkers. The problematic and meaningful contribution by Paolo Soleri and the Metabolists are analyzed to understand the reasons of the complex relation between scientism, technology and environmentalism.

El Derecho de Transmisión en el Derecho Sucesorio. Solución a la problemática entre la tesis de la adquisición directa y la tesis de la doble transmi…
2023
La institución del derecho de transmisión del artículo 1006 del Código Civil plantea la necesaria elección entre la tesis clásica o de la doble transmisión y la tesis moderna o de la adquisición directa, pues ambas conducen a resultados absolutamente diferentes en la práctica jurídica. La disyuntiva ha originado la existencia de dos corrientes doctrinales que con diversidad de argumentos han defendido de forma coherente ambas posiciones. La jurisprudencia, que tradicionalmente siguió la tesis de la doble transmisión, propició un fundamental giro con la sentencia del Tribunal Supremo de 11 de Septiembre de 2013, que optó por la tesis de la adquisición directa. La investigación de la evolució…
Laser-induced tuning of graphene field-effect transistors for pH sensing
2023
Here we demonstrate, using pulsed femtosecond laser-induced two-photon oxidation (2PO), a novel method of locally tuning the sensitivity of solution gated graphene field-effect transistors (GFETs) without sacrificing the integrity of the carbon network of chemical vapor deposition (CVD) grown graphene. The achieved sensitivity with 2PO was (25 ± 2) mV pH−1 in BIS-TRIS propane HCl (BTPH) buffer solution, when the oxidation level corresponded to the Raman peak intensity ratio I(D)/I(G) of 3.58. Sensitivity of non-oxidized, residual PMMA contaminated GFETs was 20–22 mV pH−1. The sensitivity decreased initially by 2PO to (19 ± 2) mV pH−1 (I(D)/I(G) = 0.64), presumably due to PMMA residue remova…

Reproduksjon av ulikheter, eller utdanningsrettferdighet
2023
Ideen om en skole for alle har sine røtter langt tilbake i tid (Telhaug, 1994; Solstad, 2004: Bjørnsrud & Nilsen, 2021). Fra og med L97, har det blitt vektlagt inkluderende opplæring som viktig for alle barns utvikling og læring, men menneskeverd i denne utviklingen har også vært sentralt. Alle mennesker er like mye verdt uansett av hva det er som skiller oss fra hverandre. Lærerne blir rollemodellene i dette arbeidet. Når de selv viser omsorg og respekt og ser den enkelte eleve, annerkjennes deres verdighet (Utdanningsdirektoratet, 2020). Derfor vil jeg i lys av Læreplanverket overordnede del kap. 3. Prinsipper for skolens praksis, finne ut hvordan skolen og lærerne tilrettelegger for real…
Brisures du romaneque: 'La Malédiction de la Madone', ou d'une pratique ironique du docufiction.
2023
La Malédiction de la Madone, pubblicato nel 2022, è il primo romanzo in cui Philippe Vilain, scrittore tra i maggiori rappresentanti dell’autofinzione, ab- bandona la narrazione in prima persona per un “docufiction” in terza persona basato sulla vita della camorrista Pupetta Maresca. questo cambio di rotta, an- cor più sorprendente per un autore come Vilain che aveva sempre vilipeso que- sto genere letterario, è occasione di mettere in questione le sue concezioni del romanzo e della letteratura. Ne vien fuori una narrazione tesa tra l’aspirazione a far corpo unico con la sua precedente produzione letteraria e le condizioni im- poste dalla “docufinzionalizzazione” della storia. La Maléd…

Pragmatics, Metaphor Studies and the Challenge of Mental Imagery
2023
Metaphor is considered a figurative use of language, a term that seems to recall the imagistic dimension characterizing this kind of utterances. Tzvetan Todorov (1967) speaks of “figure” as “visibility of speech”: as a figure, metaphor provides a kind of figurability to what is communicated. As Paul Ricoeur wrote in La métaphore vive (Ricoeur, 1975), metaphor makes “speech appear”. Precisely because of the reliance on the idea of figure, it is therefore not surprising that discussions on metaphor often refer to the role that mental images play in their comprehension. A long tradition holds that the formation of a mental image is fundamental for the comprehension of certain kinds of metaphor…
The Personal Repertoire and Its Materiality : Resources, Means and Modalities of Languaging
2023
The chapter is a theoretical discussion of the concept of personal repertoire and its application in the context of applied linguistics, particularly in the study of language learning and development. It questions conceptualisations that understand language learning as acquisition of abstract, decontextual and disembodied language knowledge and argues that learners’ know-how is not based on any kind of ‘mental grammar’, but on a personal repertoire of different multimodal semiotic resources. Bringing together ‘old’ and ‘new’ arguments for materialism, personal repertoires are examined focussing on how embodied agentive activity is intertwined with the socially structured environments and th…

Klynger og grønn omstilling av entreprenørielle økosystemer - En caseundersøkelse av GCE NODE og Agder
2023
Som et resultat av klimaendringer er vi nødt til å omstille oss til et samfunn med betydelig mindre negative konsekvenser for klima og miljø. I denne oppgaven har jeg sett på følgende forskerspørsmål; Hvordan kan en klynge bidra til å omstille et entreprenørielt økosystem i grønn retning? I teoridelen har jeg valgt å lene meg på teorier om klynger, grønn omstilling, entreprenørielle økosystemer og ressurser. Disse teoriene har jeg valgt fordi de kan på ulikt vis bidra til å kaste lys over problemstillingen. I korte trekk sier teorien at klynger kan bidra til grønn omstilling gjennom å oppgradere ulike ressurser på bedrifts- og systemnivå. Mulighetsrommet for grønn omstilling avhenger i stor…

Information Security Risk Assessments following Cybersecurity Breaches : The Mediating Role of Top Management Attention to Cybersecurity
2023
Information Systems (IS) research on managerial response to cybersecurity breaches has largely focused on externally oriented actions such as customer redressal and crisis response. Within the firm itself, a breach may be a symptom of systematic problems, and a narrow, siloed focus on only fixing immediate issues through technical fixes and controls might preclude other managerial actions to ensure future cybersecurity. Towards this end, Information Security Risk Assessments (ISRA) can help surface other vulnerabilities following a breach. While the role of governance in such exercises is emphasized in standards, it is undertheorized in IS research and lacks empirical evidence. We draw on t…

Computer-aided-diagnosis for ocular abnormalities from a single color fundus photography with deep learning
2023
Any damage to the retina can lead to severe consequences like blindness. This visual impairment is preventable by early detection of ocular abnormalities. Computer-aided diagnosis (CAD) for ocular abnormalities is built by analyzing retinal imaging modalities, for instance, Color Fundus Photography (CFP). The main objectives of this thesis are to build two CAD models, one to detect the microaneurysms (MAs), the first visible symptom of diabetic retinopathy, and the other for multi-label detection of 28 ocular abnormalities consisting of frequent and rare abnormalities from a single CFP by using deep learning-based approaches. Two methods were proposed for MAs detection: ensemble-based and c…

Oral decay prior to a hospital medical-surgical procedure is a risk factor for the development of postoperative complications. However, perioperative oral practices as a protective factor have not been studied. This review aims to evaluate the effectiveness of perioperative oral practices in the reduction of risk of developing postoperative complications in in-hospital medical surgical procedures. This review and meta-analysis was conducted according to Cochrane guidelines. Medline, Scopus, Scielo, and Cochrane were consulted. Articles of the previous 10 years concerning adult patients undergoing perioperative oral practices prior to hospital medical-surgical procedures, were included. Dat…
Alkynyl‐Protected Chiral Bimetallic Ag22Cu7 Superatom with Multiple Chirality Origins
2023
Understanding the origin of chirality in the nanostructured materials is essential for chiroptical and catalytic applications. Here we report a chiral AgCu superatomic cluster, [Ag22Cu7(C≡CR)16(PPh3)5Cl6](PPh4), Ag22Cu7, protected by an achiral alkynyl ligand (HC≡CR: 3,5-bis(trifluoromethyl)phenylacetylene). Its crystal structure comprises a rare interpenetrating biicosahedral Ag17Cu2 core, which is stabilized by four different types of motifs: one Cu(C≡CR)2, four -C≡CR, two chlorides and one helical Ag5Cu4(C≡CR)10(PPh3)5Cl4. Structural analysis reveals that Ag22Cu7 exhibits multiple chirality origins, including the metal core, the metal-ligand interface and the ligand layer. Furthermore, t…

A long-term vision for rural areas: a case study of Sicilian farms
2023
In line with internationally defined goals of sustainable development, European agricultural policies today have a far-sighted vision for rural areas. Using a case study approach, this paper explores how receptive rural farms in Sicily are to a long-term vision of development. The study focuses on three key factors of a long-term vision, that is, digitalisation, innovation and sustainability, to examine not only whether farms have invested in these areas but also how they perceive their role in the post-pandemic era. Empirical results provide insights into the concentration of farms in the central inland areas of Sicily without any real long-term vision of development. Nevertheless, the ana…
