EFFECT OF THE INTER-REPETITION REST LENGTH IN THE CAPACITY TO REPEAT PEAK POWER OUTPUT

2013

Background High volumes of work affect the movement technical quality, reducing the muscular capacity to develop high magnitudes of force. One of the most important parameters that we can use to regulate the training loads are the inter-repetition rests (IRR). The purpose of this study was to compare the Peak Power output (PP) magnitudes in three different inter-repetition length sets with Optimal Load (OL) in Bench Press (BP). Methods Our sample was formed by 16 male physical education students (age: 23.6±2.1 years; height: 178.2±6.9 cm; mass: 78.3±7.2 kg; 1RM: 90.2±13.9 kg; 1RM/mass: 1.15±0.16), who performed the BP test with different IRR with OL (48.8±7.2% of 1RM; 44.2±11.5 kg). After e…

A model explaining some bryozoan colonies

2008

AbstractAlthough the colonialism surely developed independently in Graptolithoidea and Bryozoa, both groups share similar patterns of astogeny. One of the common features is the presence of morphological gradients. Many attempts at its explanation were made for more than a half of the century. This paper discusses a new model of the late astogeny in some bryozoan colonies, showing a cyclic reappearance of secondary zones of astogenetic change and astogenetic repetition that cannot be explained by the single morphogen gradient theory.

The Influence of Hierarchical Masks on Masked Repetition Priming: Evidence From Event-Related Potential Investigation

2019

The discussion about relationship between prime and target has contributed to the mechanism of priming effect and object recognition. Nevertheless, the role of relationship between mask and target in those cognitive processes remains unquestioned. In the present study, we aim to investigate how mask-target hierarchical relationship may affect word priming and familiarity, by using the masked repetition paradigm and manipulating three hierarchical relationship between mask and target. It is hypothesized that a closer hierarchical relationship between mask and target is associated with a higher mask target similarity, and thereby it leads to a worse recognition performance. Our behavioral res…

Response of GAFChromic® HD-V2 film dosimeter in 10-300 Gy dose range for radiation testing of electronic devices

2019

The study reported in this paper aimed to investigate the response of a GAFChromic? HD-V2 film dosimeter in the dose range between 10 and 300 Gy, normally used to perform irradiation tests on electronic devices with a 60Co gamma-ray irradiator. The well-defined linearity of response in terms of absorbance as a function of absorbed dose, easiness of handling and data analysis of irradiated dosimeters, reproducibility, stability, and insensitivity to visible light and most of the environmental parameters, make HD-V2 film a flexible, inexpensive and reliable dose measurement device. The study has shown a fogging effect of the dosimeter response since its value changes over time. Strategies and…

Event-related brain potentials of masked repetition and semantic priming while listening to sentences.

2012

We combined for the first time electrophysiological measures and masked priming technique in sentential context, by setting up a cross-modal masked priming paradigm involving the auditory presentation of sentences. ERPs were time-locked to an auditorily presented word that was preceded by a repeated, related or unrelated pattern masked prime. We registered a two-way N400-difference between unrelated and related/repeated primes, followed by a late positive component (LPC) for repetition priming. Related primes appear to facilitate the lexical-semantic processing of the target to the same extent repeated primes do (equally attenuated N400). Repetition priming exerts additional demands (LPC), …

Predictores y efectos de la repetición de curso

2018

About a third of Spanish students will have repeated at least one school year by the time they reach 16. It is claimed that alternative policies top grade repetition should seek to provide individualised treatment and ensure early intervention. In Spain, while there is empirical evidence in support of the benefits of the former, there is little for the latter. Here, we fill this gap by combining data from two international assessments. We identify the profile of students who a) are at greatest risk of grade retention and b) are most negatively affected by the policy. Our results confirm the importance of early intervention and the need to rethink grade repetition as a one-size-fits-all poli…

Functional evaluation of a “lingual ring” oral device applied on patients affected by temporo-mandibular disorders tmds: A comparative clinical trial

2021

This study aims to evaluate the functional variations of the electromyographic response and clinical symptomatology in TMD patients. This study has been performed and compared before and after the application of a therapeutic protocol based on the use of an oral device working on the proper mandibular repositioning through the proprioceptive-based lingual re-education called “Lingual Ring”. Between January to December 2016, 32 TMD patients have been recruited out of a series of 321 individuals recruited at the Neurosensorial and Motorial Surgery Department, in Palermo (Italy). All the patients underwent the Surface Electromyography (sEMG) of Masseter and Temporal muscles, with different reg…

User Evaluation of the Smartphone Screen Reader VoiceOver with Visually Disabled Participants

2018

Touchscreen assistive technology is designed to support speech interaction between visually disabled people and mobile devices, allowing hand gestures to interact with a touch user interface. In a global perspective, the World Health Organisation estimates that around 285 million people are visually disabled with 2/3 of them over 50 years old. This paper presents the user evaluation of VoiceOver, a built-in screen reader in Apple Inc. products, with a detailed analysis of the gesture interaction, familiarity and training by visually disabled users and the system response. Six participants with prescribed visual disability took part in the tests in a usability laboratory under controlled con…
