Stress Echocardiography and Strain in Aortic Regurgitation (SESAR protocol): Left ventricular contractile reserve and myocardial work in asymptomatic…
2020
Objectives: To analyze left ventricular (LV) myocardial deformation and contractile reserve (CR) in asymptomatic patients with severe aortic regurgitation (AR) at rest and during exercise, and their correlation with functional capacity. Background: The natural history of chronic AR is characterized by a prolonged silent phase before onset of symptoms and overt LV dysfunction. Assessment of LV systolic function and contractile reserve has an important role in the decision-making of AR asymptomatic patients. Methods: Standard echo, lung ultrasound, and LV 2D speckle tracking strain were performed at rest and during exercise in asymptomatic patients with severe AR and in age- and sex-comparabl…
Apraktās ielejas trīsdimensionāla modeļa izveide, izmantojot gravitācijas mērījumus
2020
Bakalaura darba “Apraktās ielejas trīsdimensionālā modeļa izveide, izmantojot gravitācijas mērījumus”, mērķis ir lokalizēt apraktās ielejas morfoloģiskās īpašības, veidojot trīsdimensionālu un divdimensionālus modeļus, veikt interpretāciju par tās ģenēzi, izmantojot gravitācijas lauka mērīšanas metodes. Pētījuma ietvaros veikti gravitācijas mērīšanas darbi, faktiskā materiāla apkopošana, laboratorijas darbi un kamerālie darbi. Rezultātā tika izveidots trīsdimensionāls un divdimensionāli modeļi no gravitācijas anomālijām. Pētījumā iegūtie rezultāti norāda, ka korelējot urbumu datus ar gravitācijas mērīšanas metodi ir iespējams noteikt apraktās ielejas morfoloģiju.
L'anfiteatro romano di Termini Imerese : ricostruzioni virtuali e vicende storico/architettoniche del sito urbano
2018
The work we present is inspired by the results of an architectural survey that was carried out on the architectural remains of the Roman Amphitheater of Termini Imerese, in order to its possible conjectural reconfiguration and three-dimensional remodeling in a VRML or augmented-reality context. All this has been thought to benefit the development of cultural and archaeological tourism in the site itself. The approach to the site and to the ancient building has, however, focused on urban and territorial analysis since the first inspections, considering mainly the peculiarities that distinguish the historical / architectural vicissitudes of the site. In the Medieval Age the Jewish Quarter was…
De la perception sensorielle à la consommation du vin. Partie 1/2 : Mécanisme de la perception sensorielle : reflet de la réalité
2010
National audience; Afin de percevoir son environnement et de pouvoir réagir en conséquence, l’être humain est équipé de capteurs sensoriels. Ces capteurs constituent une interface entre le sujet et le monde extérieur et quelle que soit la stimulation extérieure, ils mettent en jeu les mêmes mécanismes sensoriels. Lorsque les capteurs sensoriels rentrent en contact avec un stimulus, les informations engendrées sont amplifiées, puis transmises au système nerveux central sous forme de signaux électriques (Mac Leod et Sauvageot, 1986) après avoir été progressivement filtrées, réduites et stabilisées. Ces informations électriques sont caractérisées d’une part par une masse globale d’activité, co…
Dimensions of the Relationship between the Individual and Her Unique Worldview Construction
2021
Each individual constructs his own private worldview using elements from established worldview traditions. The biographical character of this formation makes this the individual’s “Unique Worldview Construction” (UWC). The purpose of this theoretical study is to analyse the dynamic relationship between the individual and her own UWC. It describes more how than what he believes in or denies. The variation is exceedingly complex. To make it accessible, the complexity is crystallized into seven dimensions: (1) The authority structure deals with the individual’s perception of herself as being superordinate/subordinate to her own UWC. (2) The importance dimension analyses the span from indiffere…
The impact of two-dimensional perfectionism on burnout and eating disorders in young Finnish athletes : comparison between males and females
2014
Matilda Sorkkila, 2014. The impact of two-dimensional perfectionism on burnout and eating disorders in young Finnish athletes: comparison between males and females. Master’s Thesis in Sport and Exercise Psychology. Department of Sport Sciences. University of Jyväskylä. 40 p. Even though it has been argued that perfectionistic strivings might be adaptive and perfectionistic concerns might be maladaptive in sports, only few studies have viewed these dimensions in relation to athletes’ mental health. Two mental health problems that have been found in elevated amounts in young elite athletes are burnout and eating disorders. It has been proposed that perfectionism might impact the development o…
Dimensioni di attaccamento e formazione delle visioni del mondo e delle ideologie
2013
The aim of this study was to investigate the role of attachment dimensions in framing worldviews and socio-political attitudes. A study on 178 Italian university students in Palermo was conducted. A causal model is tested where social conformity, toughmindedness, and insecure attachment dimensions were considered antecedents, and right-wing authoritarianism and social dominance orientation were the dependent variables. The structural equation modeling showed a good fit. The model evidenced the mediation role of worldviews in the relation between social conformity, toughmindedness, attachments, and socio-political attitudes. The avoidance attachment predicted world as competitive jungle, the…

Preparation and characterisation of optical and optoelectronic devices based in two-dimensional semiconductors
2020
In the Materials Science field, two-dimensional materials have gained the scientific community attention in recent years. The change and the appearance of novel properties when their thickness is reduced to nanometric scale has special interest for its fundamental properties study for, from this base, the design and its implementation in devices. The wide variety of materials with the possibility of being exfoliated at the two-dimensional level opens the field to different applications, from optoelectronic devices, detection and sensing, energy storage, catalysis, medical applications and quantum information technologies, among others. This thesis gathers results in both directions: a funda…
Secondary metabolites of the lichen-associated fungus Apiospora montagnei
2017
Abstract The endolichenic fungus Apiospora montagnei isolated from the lichen Cladonia sp. was cultured on solid rice medium, yielding the new diterpenoid libertellenone L (1), the new pyridine alkaloid, 23-O-acetyl-N-hydroxyapiosporamide (2) and the new xanthone derivative 8-hydroxy-3-hydroxymethyl-9-oxo-9H-xanthene-1-carboxylic acid methyl ether (3) together with 19 known compounds (4–22). The structures of the new compounds were elucidated by 1D and 2D NMR spectra as well as by HRESIMS data. The absolute configuration of the new 6,7-seco-libertellenone derivative 1 was determined by single-crystal X-ray diffraction. Four additional known compounds 23–26 were isolated when NaCl or NH4Cl w…
