Complex power distribution analysis in plates covered with passive constrained layer damping patches
2012
International audience; The vibration of a plate partially covered with a passive constrained layer damping (PCLD) patch is studied from an energetic point of view. The damped plate is excited by an acoustic plane wave. The study is done with a numerical two-dimensional multilayer plate model. Results of the present model are compared to those obtained with three-dimensional finite element models. It is shown that the present model gives accurate results, even for the layer's inner behavior. It is less expansive in terms of computational cost; hence, it can simulate efficiently the structure for higher frequencies. Mathematical formulas for complex mechanical power are presented, and the li…
Data from: Assessing metabolic constraints on the maximum body size of actinopterygians: locomotion energetics of Leedsichthys problematicus (Actinop…
2019
Maximum sizes attained by living actinopterygians are much smaller than those reached by chondrichthyans. Several factors, including the high metabolic requirements of bony fishes, have been proposed as possible body-size constraints but no empirical approaches exist. Remarkably, fossil evidence has rarely been considered despite some extinct actinopterygians reaching sizes comparable to those of the largest living sharks. Here, we have assessed the locomotion energetics of Leedsichthys problematicus, an extinct gigantic suspension-feeder and the largest actinopterygian ever known, shedding light on the metabolic limits of body size in actinopterygians and the possible underlying factors th…
Attitudes of elementary school teachers towards inclusive education in Ecuador
2020
Resumen Las actitudes de los docentes hacia la inclusión son un factor relevante para permitir que las políticas educativas inclusivas puedan materializarse verdaderamente en prácticas inclusivas. Estas actitudes se ven influenciadas por diferentes variables, entre las que se encuentran la formación y experiencia en el ámbito de la inclusión y las condiciones y recursos disponibles para llevar a cabo prácticas educativas. El objetivo del presente trabajo es analizar las actitudes hacia la inclusión educativa en una muestra de 66 docentes de 15 centros educativos de la ciudad de Cuenca (Ecuador), mediante una escala tipo Likert de 23 ítems. Los resultados muestran que los docentes presentan …
Aequorin-expressing yeast emits light under electric control
2011
In this study, we show the use of direct external electrical stimulation of a jellyfish luminescent calcium-activated protein, aequorin, expressed in a transgenic yeast strain. Yeast cultures were electrically stimulated through two electrodes coupled to a standard power generator. Even low (1.5. V) electric pulses triggered a rapid light peak and serial light pulses were obtained after electric pulses were applied periodically, suggesting that the system is re-enacted after a short refraction time. These results open up a new scenario, in the very interphase between synthetic biology and cybernetics, in which complex cellular behavior might be subjected to electrical control.
Co-created training program to promote active ageing in people with Down syndrome
2020
Abstract Background Population ageing is a current challenge for the European society. Specifically, People with Down Syndrome (PDS) are living longer than before, reaching some of them around 60 years old. However, it is known that they show premature ageing that in some cases may be misled with Alzheimer first signs. Hence, it is crucial to promote an Active Ageing (AA) and healthy living in this specific population by keeping their cognitive, physical and emotional functions, and also promoting social activities such as community participation. In such way, their Quality of Life (QoL) will be increased. Objectives The main objective of this study was to co-design a Training Program (TP) …
Specific transfer effects following variable priority dual-task training in older adults
2016
International audience; Purpose: Past divided attention training studies in older adults have suggested that variable priority training (VPT) tends to show larger improvement than fixed priority training (FPT). However, it remains unclear whether VPT leads to larger transfer effects. Methods: In this study, eighty-three older adults aged between 55 and 65 received five 1-hour sessions of VPT, FPT or of an active placebo. VPT and FPT subjects trained on a complex dual-task condition with variable stimulus timings in order to promote more flexible and self-guided strategies with regard to attentional priority devoted to the concurrent tasks. Real-time individualized feedback was provided to e…
The determinants of subjective economic well-being: an analysis on Italian-Silc data
2011
Using Italian data on Income and living conditions for the year 2005, the paper investigates the main determinants of households’ subjective economic well-being by means of a Partial Proportional Ordered Logit Model. According to a joint subjective and objective perspective of analysis, we use as dependent variable the perceived ability of households to make ends meet. Whereas, we use as explanatory variables some objective aspects of living conditions relating to housing, financial equilibrium, possession of durables and quality of residence place and some socio-demographic characteristics. The empirical results show that the financial strain is the most relevant dimension of living condit…
Want to Impact Physical, Technical, and Tactical Performance during Basketball Small-Sided Games in Youth Athletes? Try Differential Learning Beforeh…
2020
This study aimed to analyze the acute effect of small-sided games, based on differential learning, on the physical, technical, and positioning performance of young basketball players. Eight basketball players under 13 (U13) participated in this study. A total of eight sessions involving half-court small-sided games (4 sets ×
Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…
2020
This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ±
2017
Creatine kinase (CK) is a marker for muscle cell damage with limited potential as marker for training load in strength training. Recent exercise studies identified cell free DNA (cfDNA) as a marker for aseptic inflammation and cell damage. Here we overserved in a pilot study the acute effects during strength exercise and chronic effects of regular strength training on cfDNA concentrations over a period of four weeks in three training groups applying conservation training (CT) at 60% of the 1 repetition maximum, high intensity-low repetition training (HT) at 90% of the 1 repetition maximum and differential training (DT) at 60% of the 1 repetition maximum. EDTA-plasma samples were collected b…
