Kształtowanie intuicji matematycznych w trakcie pozaszkolnej aktywności dziecka
2016
Rodzice jako partnerzy procesu rozbudzania dziecięcej aktywności matematycznej
2017
Children learn in a spontaneous and continuous way: when they look at an object, paying more attention to it, or when they notice something accidentally, when they perform simple actions of daily routine, or even when they turn to a grown-up with a question. Therefore, forming proper mathematical intuition should not be limited merely to activities at school, but should proceed natural, also during everyday activities, while playing games or talking to other children or the parents. The individual’s own activity plays a particular role in the development of mathematical skills in children. And it is parents who have the greatest say as regards the lines along which the child’s activity is d…

Complete One-Loop Renormalization of the Higgs-Electroweak Chiral Lagrangian
2018
The electroweak sector of the Standard Model can be formulated in a way similar to Chiral Perturbation Theory (ChPT), but extended by a singlet scalar. The resulting effective field theory (EFT) is called Higgs-Electroweak Chiral Lagrangian (EWCh$\mathcal{L}$) and is the most general approach to new physics in the Higgs sector. It solely assumes the pattern of symmetry breaking leading to the three electroweak Goldstone bosons (i.e. massive $W$ and $Z$) and the existence of a Higgs-like scalar particle. The power counting of the EWCh$\mathcal{L}$ is given by a generalization of the momentum expansion of ChPT. It is connected to a loop expansion, making the theory renormalizable order by ord…
Exploring the explosive‐effusive transition using permanent ultra‐violet cameras
2017
Understanding the mechanisms that cause effusive eruptions is the key to mitigating their associated hazard. Here we combine results from permanent ultraviolet (UV) cameras, and from other geophysical observations (seismic very long period, thermal, and infrasonic activity), to characterize volcanic SO2 flux regime in the period prior, during, and after Stromboli's August–November 2014 effusive eruption. We show that, in the 2 months prior to effusion onset, the SO2 flux levels are 2 times average level. We explain this anomalously high SO2 regime as primarily determined by venting of rapidly rising, pressurized SO2-rich gas pockets produced by strombolian explosions being more frequent and…
The efficacy and safety of nutrient supplements in the treatment of mental disorders: a meta‐review of meta‐analyses of randomized controlled trials
2019
The role of nutrition in mental health is becoming increasingly acknowledged. Along with dietary intake, nutrition can also be obtained from "nutrient supplements", such as polyunsaturated fatty acids (PUFAs), vitamins, minerals, antioxidants, amino acids and pre/probiotic supplements. Recently, a large number of meta-analyses have emerged examining nutrient supplements in the treatment of mental disorders. To produce a meta-review of this top-tier evidence, we identified, synthesized and appraised all meta-analyses of randomized controlled trials (RCTs) reporting on the efficacy and safety of nutrient supplements in common and severe mental disorders. Our systematic search identified 33 me…

Métodos de entrenamiento de fuerza alternativos para incrementar la activación muscular en ejercicios de empuje
2016
Introducción. Los movimientos en los que se empuja o presiona con los brazos a una resistencia externa constituyen un elemento clásico dentro de los programas de entrenamiento de la fuerza. Tradicionalmente se han empleado ejercicios convencionales con pesos libres y máquinas con los que se conseguía alcanzar intensidades de activación muscular altas. Sin embargo, tratando de incrementar en mayor medida la intensidad en este tipo de ejercicios, durante los últimos años se han comenzado a utilizar nuevos medios y métodos alternativos (por ejemplo utilizando dispositivos de suspensión, resistencia elástica o tratando de activar músculos de forma selectiva). No obstante, es escasa la evidencia…

Six-dimensional measurements of trains of high brightness electron bunches
2015
Trains of ultrashort electron pulses with THz repetition rate, so-called comblike beams, are assuming an ever growing interest in plasma-based acceleration. In particle-driven plasma wakefield acceleration (PWFA), a train of driver bunches with separation of the order of plasma wavelength, i.e., 300 μm, resonantly excites a plasma wake, which accelerates a trailing witness bunch, injected at the accelerating phase. Comblike beams have great potentialities in different fields of applications. In particular, radiation sources, such as free-electron lasers and THz radiation, take advantage from the possibility to tailor electron beams modulated both in time and energy, to customize emission ba…
