A New Theoretical Approach on Teenage Cyclist-Vehicle Crash
2016
Data obtained in teenage cyclist impact against three vehicles (sedan, SUV and Pick Up), tested in previous works, are analyzed to verify the theoretical results by the coupling of momentum conservation principle and energy conservation principle. The speed of vehicle and thorax are compared with theoretical ones, obtaining an excellent agreement. Following the results found in the literature, particular emphasis is done on teenager cyclist thorax and head speeds, indicating that the cyclist speed can be theoretically until 1,41 times the impact speed, while greater values, until 2, are obtained in the simulations. A small slowing of the vehicle is found theoretically and in the simulations…
Device-based physical activity levels among Finnish adolescents with functional limitations
2019
Background Monitoring physical activity among young adolescents with disabilities is a top academic priority. People with disabilities are a diverse group with various abilities in different human functioning. Therefore, we used a novel approach through functional limitations as a marker for disabilities and examined physical activity levels. Objective To investigate the levels and differences in light (LPA) and moderate-to-vigorous (MVPA) intensity physical activity between young adolescents with and without functional limitations. Methods The study included young adolescents (n = 1436) aged 11–15 years olds who attended general schools that were part of the 2016 Finnish School-aged Physic…
CCTVCV: Computer Vision model/dataset supporting CCTV forensics and privacy applications
2022
The increased, widespread, unwarranted, and unaccountable use of Closed-Circuit TeleVision (CCTV) cameras globally has raised concerns about privacy risks for the last several decades. Recent technological advances implemented in CCTV cameras, such as Artificial Intelligence (AI)-based facial recognition and Internet of Things (IoT) connectivity, fuel further concerns among privacy advocates. Machine learning and computer vision automated solutions may prove necessary and efficient to assist CCTV forensics of various types. In this paper, we introduce and release the first and only computer vision models are compatible with Microsoft common object in context (MS COCO) and capable of accurately…
La violència de gènere en el discurs televisiu. Procés de producció i representació mediàtica
2015
El principal objectiu de la tesi doctoral és analitzar com i per què es representa la violència de gènere en els informatius a l’Estat espanyol. L’atenció a la representació mediàtica de la violència de gènere ha estat un vast camp d’estudi en les darreres dècades. Donada la seua importància per situar els horitzons interpretatius dels fenòmens socials, els mitjans de comunicació esdevenen un camp privilegiat per estudiar la lògica de la producció, acumulació i circulació discursiva ja que es fonamenten en valors i percepcions d’un determinat ordre simbòlic. Les transformacions que ha viscut la representació mediàtica de la violència de gènere al llarg dels darrers 15 anys ens permeten prob…
Taxonomy and ecology of metazoan parasites of otariids from Patagonia, Argentina : adult and infective stages
2013
At present, the metazoan parasite fauna of most species of otariids is generally poorly known, in part because these marine mammals are mostly protected and, therefore, sampling is limited to specimens stranded on the coast or captured as by-catch in fisheries. Similar problems also occur for the larval stages of gastrointestinal helminths of otariids. For most of these parasite species, the specific identity of the intermediate/paratenic of hosts is unknown and, therefore, many stages of their life cycles remain to be described. Similarly, little is known about the routes of transmission of these parasites between intermediate/paratenic hosts to their otariids definitive hosts. The present…

Child socioemotional behavior and adult temperament as predictors of physical activity and sedentary behavior in late adulthood
2023
Background Most studies investigating the association of temperament with physical activity and sedentary behavior have examined children or adolescents, employed cross-sectional or longitudinal designs that do not extend from childhood into adulthood, and utilized self- or parent-reported data on physical activity and sedentary behavior. This longitudinal study investigated whether socioemotional behavior in childhood and temperament in middle adulthood predict accelerometer-measured physical activity and sedentary behavior in late adulthood. Methods This study was based on the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). Socioemotional behavior (behavioral ac…
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
The Case of Insertional Adductor Tendinopathy of an International-Level 3,000-m Steeplechase Runner
2021
Background: Groin pain is a frequent condition among athletes. One of the causes of groin pain is tendinopathy, a frequently diagnosed medical condition, which can also occur in the adductor muscles. Despite the high prevalence of this medical condition among athletes, it is infrequent to observe tendinopathic groin pain in steeplechase runners. The aim of this case study is to describe the case of an international-level 3,000-m steeplechase runner with groin pain, who was subsequently diagnosed with adductor insertional tendinopathy.Case Presentation: We present the case of an Italian 3,000-m steeplechase and long distance runner, Ala Zoghlami (180 cm, 57 kg), with groin pain, diagnosed as…
Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications
2015
The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…
