COVID‐19 in older adults: What are the differences with younger patients?
2020
Aim The present study aimed both to gain knowledge on the distinctive clinical characteristics of older adults with coronavirus disease 2019 (COVID‐19), in comparison with those of younger patients, and to identify risk factors for mortality. Methods A retrospective observational study was carried out of patients consecutively admitted to Doctor Peset University Hospital, Valencia (Spain) for COVID‐19 from 11 March to 28 April 2020. Every case was diagnosed by reverse transcription polymerase chain reaction or by serology test to detect antibodies. Demographic details, clinical characteristics, laboratory findings on admission and complications of each case were collected from electronic me…
A Single-Center (Sibiu, Romania), Retrospective Study (March–November 2020) of COVID-19 Clinical and Epidemiological Features in Children
2021
The aim of this study was to describe and analyze epidemiological and clinical features of children screened for COVID-19 at Sibiu Pediatric Clinical Hospital during the first 9 months (March–November) of coronavirus disease pandemic in Romania. A total of 203 pediatric patients with a confirmed diagnosis of COVID-19 were included in the study. The median age of the patients was 121 (IQR 18–181) months and 52.22% had mild clinical type with pneumonia, 35.47% were moderate cases, 3.94% severe cases, 0.99% critically ill cases and 7.39% were asymptomatic. The most common symptoms were fever (n = 130, 64.03%), nasal congestion (n = 138, 67.98%), cough (n = 128, 63.05%) followed by sore throat …

Ainava un identitāte – Latvijas simtgades konteksts
2018
Tuvojas Latvijas simtgade. Ainavā var būt redzamas Latvijas identitātes izpausmes. Nacionālās ainavas Latvijā vēl nav noteiktas. Tajās var būt ainavas raksturīgās, unikālās iezīmes, simboli Latvijas dabai, kultūrai. Nacionālās ainavas var izvirzīt, apzinoties ainavu vērtības, ar tautas līdzdalību. Tās stāsta arī par latvieti, latvieša identitāti - vērtībām, kas ainavā uzrunā. Šīs ainavas var kalpot, piemēram, lai saliedētu tautu. Pētījuma mērķis- izmantojot pieteiktos “Ainavu dārgumus” un “Foreign stories in Latvia” intervijas, raksturot Latvijas tēlu. Galvenie rezultāti- latvieša identitātes iezīmes, ainavas iezīmes. Plašākai izpētei izvēlētā Latgales plānošanas reģiona “Ainavu dārgumu” pi…
Obtención de marcadores moleculares para la identificación de variedades de naranjas navel
2018
La mayor parte de variedades de naranja dulce que se cultivan en la actualidad proceden de mutaciones espontáneas de una variedad materna. Este fenómeno determina que las variedades derivadas sean en la práctica cuasi clones de la variedad materna, lo que desemboca en una dificultad para la identificación varietal tradicional mediante caracteres morfológicos. Una manera de mejorar la identificación varietal basada en caracteres morfológicos es complementarla con una identificación varietal basada en el uso de marcadores moleculares. Este trabajo consiste en la utilización de herramientas genómicas desarrolladas por el consorcio público-privado Citruseq-Citrusgenn en el Centro de Genómica de…
Study of Intumescent Coatings Growth for Fire Retardant Systems in Naval Applications: Experimental Test and Mathematical Model
2022
Onboard ships, fire is one of the most dangerous events that can occur. For both military and commercial ships, fire risks are the most worrying; for this reason they have an important impact on the design of the vessel. The intumescent coatings react when heated or in contact with a living flame, and a multi-layered insulating structure grows up, protecting the underlying structure. In this concern, the aim of the paper is to evaluate the intumescent capacity of different composite coatings coupling synergistically modeling and experimental tests. In particular, the experiments have been carried out on a new paint formulation, developed by Colorificio Atria S.r.l., in which the active comp…
The Impact of Grain Size Composition and Organic Matter Content on Magnetic Susceptibility of Anthropogenically Transformed Bottom Sediments, as Exem…
2018
The article presents the results of an analysis of the surface layer of bottom sediments in the naval harbour in Hel. During field work conducted in June 2013, 54 sediment samples were collected. The aim of the study was to examine magnetic susceptibility of harbour sediment as a parameter determining the degree of anthropopressure. As part of laboratory tests, grain size analysis was performed in order to determine organic matter content and magnetic susceptibility of the sediment. The study also measured the impact of environmental factors on fluctuations in the other studied parameters. The results demonstrate increased dynamics of sedimentary environment in the open part of the naval ha…
Peripersonal Visuospatial Abilities in Williams Syndrome Analyzed by a Table Radial Arm Maze Task
2020
Williams syndrome (WS) is a genetic deletion syndrome characterized by severe visuospatial deficits affecting spatial exploration and navigation abilities in extra-personal space.To date, little is known about spatial elaboration and reaching abilities in the peripersonal space in individuals with WS. The present study is aimed at evaluating the visuospatial abilities in individuals with WS and comparing their performances with those of mental age-matched typically developing (TD) children by using a highly sensitive ecological version of the Radial Arm Maze (table RAM). We evaluated 15 individuals with WS and 15 TD children in two different table RAM paradigms: the free-choice paradigm, ma…
A Navigation and Augmented Reality System for Visually Impaired People
2021
In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…
