Music-related motor skills in pianists - Predictors of skill acquisition in childhood and of maintenance in adulthood
2009
Background and Study Aims: Previous research on musical performance achievement has focused on the overall musical performance and on musical subskills. Two studies were conducted to identify predictors of motor skill acquisition in children pianists and of long-term development of motor skills in expert pianists in a relevant musical context. Methods: Motor skills at the piano were assessed in standardized C major scale playing. For each participant, overall temporal unevenness of note onsets was calculated as the median of the mean standard deviations of inter-onset intervals of both hands and playing directions. Study 1: Motor performance was tested in 30 piano playing children. Informat…
Characterization of thin plastic foils for applications in X-ray optics technology
2007
Thin plastic foils are being investigated to build shell optics for X-ray telescopes. Compared to polished glass optics, the advantage is in terms of increased collecting area, light weight and lower cost. Plastic material is also desirable to allow deformation into a complete surface of revolution. We collected plastic materials of common use for industrial applications and also specialty materials developed for the electronic industry. A comparative study was then performed to evaluate the optical quality of the selected plastic films. Surface analysis was carried out with topographic instruments to investigate the microroughness of our samples at different scan lengths. Preliminary resul…

The employee is not, as yet, separated from the working environment by their 'humanity'. The working environment becomes a kind of network, connected to other employees and the enterprise through invisible threads of dependencies and influences woven from personal data that can be algorithmically arranged and given new meaning and ownership. Authority and subordination are their physical representations. These interdependencies have one thing in common, regardless of the type of organised complexity. Each employee is equally subjected to informational authority, regardless of their profession, tion and industry. Everywhere, they are equally networked, subject to the same pressure and superv…
La revista Cuadernos de Ágora y sus relaciones con Latinoamérica
2014
Cuadernos de Agora (1956-1964) was a post-war magazine directed by the poet Concha Lagos. His short story (nearly eight years) was characterized by the independent and participatory spirit, also tended bridges to other magazines outside the Spanish territory, both in Europe and in Latin America. This text present one summary of poetic relationship between Spain and Latin America from the perspective of Cuadernos de Agora.
Od scenografii teatralnej do scenografii społeczno--politycznej
2020
The paper is an attempt at comprehensive conceptualization of the category of ‘social and political scenography’. The author’s reference point are artistic practices (institutional theater, field theater, happenings), various performances, rituals of social life (e.g. funerals), public assemblies, including religious ones, but also different forms of unconventional participation (manifestations, demonstrations). The concept of “performance” was adopted as the common denominator of all these practices. The author tried to prove the thesis, that the social scenography (just like contemporary theater scenography) was not only a decorative background for collective social activities, artistic p…
RILEM TC 279 WMR round robin study on waste polyethylene modified bituminous binders: advantages and challenges
2022
inter-laboratory experiments were designed to evaluate the impact of plas- tic waste blended directly in bitumen and to assess the properties, using conventional and advanced bituminous binder testing. The blends tar- geted 5% of plastic waste in 95% bitumen, using two types of polyethy- lene (PE) primary (pellets) and secondary (shreds) waste. The experiments showed that the addition of PE waste to bitumen does not alter the chem- istry of the bitumen, the blending is physical. The DSR results indicate a strong dependency on the testing temperature as at low temperatures the composite material bitumen and PE behave both elastically whereas, at higher temperatures, the bitumen becomes visco…
The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power …
2021
The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1+2.6 years, 100 m performance: 11.5+0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4]…
An Innovative Power Line Communication solution For Medium Voltage Smart Grids Applications
2018
This paper summarizes the authors research activity concerning the design, modeling and experimental characterization of a new coupling system for medium voltage (MV) narrow band power line communications (NB-PLC). The proposed solution has been patented by authors and it exploits the capacitive divider of voltage detecting systems (VDSs) normally used to reveal the mains voltage presence, thus avoiding the use of dedicated MV couplers. In the following, the modeling of the VDS capacitive divider is presented and the interface card design is described, based on simulation of the whole PLC transmission channel. Laboratory tests are also presented. Finally, the results are shown of an on-fiel…
I Symposium of Elite Performance in Combat Sports
2017
This report presents a summary of the I Symposium of Elite Performance in Combat Sports held in Madrid, May 27, 2017. The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Prezentācijas lai attīstītu vidusskolas skolēnu publiskās uzstāšanās prasmes
2019
21. gadsimts prasa, lai ikviens būtu komunikabls un pašpārliecināts. Prezentācijas ir labs līdzeklis, uz ko balstīties situācijās, kad skolēni nejūtas pašpārliecināti uzstājoties. Diplomdarba tēma ir prezentācijas lai attīstītu vidusskolu audzēkņu publiskās uzstāšanās prasmes. Teorētiskā daļā ir aprakstīti vidusskolas skolēni 21. gadsimta skolā, viņu uzstāšanās prasmes, uzstāšanās prasmju attīstība prezentāciju laikā un prezentāciju daudzveidība. Praktiskajā daļā autore analizē anketas par prezentācijām kā vidusskolas audzēkņu uzstāšanās prasmju attīstītājām. Rezultāti liecina, ka studenti un angļu valodas skolotāji novērtē prezentācijas kā uzstāšanās prasmju attīstītājas. Pētījums apstipri…
