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.
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…
Reasoning of using causation and effectuation logic : implications on start-up performance and internationalization
2018
New start-up companies are the basis for expansive companies. Expansive companies are extremely important for employment and for business growth. For this reason, it is important to know the processes how start-up companies are built up. In this research, the relations between prior entrepreneurial experience, prior international experience, effectuation and causation, financial performance and degree of internationalization were studied among the Finnish knowledge intensive business services (KIBS) start-up companies. The research utilized mixed methods and comprised of two parts, qualitative and quantitative parts. The former part included setting the research propositions based on the li…
Modelo de competencia docente del profesor de medicina en la UNAM
2011
Resumen basado en el de la publicación Título, resumen y palabras clave en español e inglés Disponible la versión en inglés Se presenta un modelo de competencia docente del profesor de medicina. Fue generado a partir de un modelo conceptual preexistente: dicho modelo se sometió al juicio de expertos quienes seleccionaron las competencias de mayor impacto, construyéndose un perfil de competencias. Se generó un instrumento basado en la opinión de los estudiantes y otro de autoevaluación, siendo ambos validados por 18 expertos en evaluación y aplicándose a 2281 estudiantes y 107 profesores. Asimismo, se obtuvo un comportamiento psicométrico adecuado que permitió establecer un modelo acorde a l…
Proton Direct Ionization in Sub-Micron Technologies : Test Methodologies and Modelling
2023
Two different low energy proton (LEP) test methods, one with quasi-monoenergetic and the other with very wide proton beam energy spectra, have been studied. The two test methodologies have been applied to devices that were suggested from prior heavy-ion tests to be sensitive to proton direct ionization (PDI). The advantages and disadvantages of the two test methods are discussed. The test method using quasi-monoenergetic beams requires device preparation and high energy resolution beams, but delivers results that can be interpreted directly and can be used in various soft error rate (SER) calculation methods. The other method, using a heavily degraded high energy proton beam, requires littl…
Validation of a Work Engagement Scale. Profi les associated with high Performance and Job Satisfaction
2017
El objetivo principal de este estudio consistía en la validación de una escala para la evaluación del work engagement -compromiso con el trabajo-, considerado como una presencia psicológica en el rol que incluye atención, absorción y energía dirigida a tareas laborales. Mediante análisis factorial confirmatorio, estimación de la consistencia interna y evidencias de validez convergente y discriminante, se confirma que la Escala Argentina de Compromiso con el Trabajo es una prueba válida y confiable para su uso en población argentina. Además, se buscó analizar si existen diferencias en los niveles de work engagement de acuerdo con variables individuales y organizacionales. Se observaron mayor…
