Power Line Communication in Medium Voltage Systems: Characterization of MV Cables
2008
The aim of this paper is to illustrate the development of a theoretical and experimental study on the characterization of medium voltage (MV) cables in the frequency range 25-200 kHz. Two transmission line configurations, line-ground and line-line, were considered in order to evaluate the main parameters, such as the characteristic impedance and the attenuation constant alpha. A simplified model of the line-ground configuration is proposed which allows one to evaluate the characteristic impedance and the attenuation constant by means of geometrical dimensions. The model was verified by experimental measurements on commonly used MV cables, RG7H1R, with an aluminium core of different sections…
Design of a Hybrid Electric Power-Split Transmission for Braking Energy Recovery in a Drilling Rig
2022
Despite the promising potential of the hybrid electric power-split layout, its broader market penetration is prevented by the large number of feasible solutions and the constructive complexity, which overcomplicate the design process. Moreover, due to the lack of relevant literature references, the power-split transmissions design is even more difficult if concerning applications outside the automotive and agricultural sectors. In this paper, a general parametric model already available in the literature to design a single-mode power-split transmission with up to two planetary gear sets and six ordinary gear sets was applied to hybridize an oil drilling rig to recover energy braking during …
Phrasal Europeanisms in Llibre de paraules e dits de savis e filòsofs. A diachronic and comparative study.
2016
En aquest treball ens hem proposat analitzar alguns dels europeismes fràsics presents al Llibre de paraules e dits de savis e filòsofs (entre 1291 i 1295) de Jafudà Bonsenyor, metge jueu de Barcelona. Es tracta d’una obra escrita en llengua catalana, a partir de “llibres aràbics”, útil per a l’estudi de la transmissió sapiencial d’Orient a Occident, a través d’Al Àndalus i Catalunya. Per a l’anàlisi, hem aplicat el mètode de concordances fràsiques, a partir del qual hem seleccionat, descrit, documentat, contrastat i validat deu proverbis com a europeismes. Ens ha interessat sobretot la localització i comparació de les codificacions en llatí medieval i llengües europees de l’època estudiada …
Historie (nie)opowiedziane. Problemy przekazu międzypokoleniowego i socjalizacji historycznej w rodzinach na Śląsku Opolskim
2016
The article presents the research about the ntergenerational transmission in families in the Opole Silesia. This community co-creates the descendants of the native population, peoples displaced from the former eastem borderlands, and immigrants population from the central Polish and other regions. The aim of the study was to investigate the social and cultural determinants of intergenerational transmission and its’ contents and forms in families in the Opole Silesia. The generations which grew up during the post-war period are different from the previous ones by social and cultural factors, which are important for the continuity of intergenerational transmission, such as: family model, the …
RAB18 Loss Interferes With Lipid Droplet Catabolism and Provokes Autophagy Network Adaptations
2020
Autophagy is dependent on appropriate lipid supply for autophagosome formation. The regulation of lipid acquisition and the autophagy network response to lipid-limiting conditions are mostly elusive. Here, we show that the knockout of the RAB GTPase RAB18 interferes with lipid droplet catabolism, causing an impaired fatty acid release. The resulting reduced lipid-droplet-derived lipid availability influences autophagy and provokes adaptive modifications of the autophagy network. These adjustments include increased expression and phosphorylation of ATG2B as well as augmented formation of the ATG12-ATG5 conjugate. Moreover, ATG9A shows an enhanced phosphorylation at amino acid residues tyrosi…
Experimental Characterization and Acoustic Correction of a Multipurpose Performance Hall: The Italian Theatre “Cavallino Bianco”
2022
This study presents the retrofit acoustic dq1esign of the Italian theatre “Cavallino Bianco”. In its historical configuration, the hall had a curved roof with a pressed-plant fiber ceiling, which was demolished and replaced with a wooden roof without a false ceiling, leading to an increase in volume and a worsening of the reverberation time. This study proposed the realization of a wave ceiling and the application of sound-absorbing and reflecting panels on the walls, which have already been implemented. These modifications have affected the acoustic characterization of the theatre, as shown both through on-site measurements during the main construction phases and through numerical simulati…

Prenatalny okres życia człowieka
2020
Rozwój człowieka w prenatalnym okresie życia interesował ludzi już w czasach starożytności. I choć do dziś prowadzi się wiele dyskusji na temat początku ludzkiego życia, należy stwierdzić, że rozwój poczętego dziecka oraz jego kompetencje wskazują na to, że od początku swojego istnienia jest to osoba aktywna i samosterowalna, która czuje, zapamiętuje, uczy się, posiada pewien poziom świadomości. Radzi sobie z trudnościami hamującymi jego rozwój, przystosowuje do zmiennych warunków życia nie tylko wewnątrz-, ale i zewnątrzmacicznego, nabywa pewnych nawyków i przyzwyczajeń, reaguje w indywidualny, charakterystyczny dla siebie sposób

Is individual- and school-level teacher burnout reduced by proactive strategies?
2021
There is provisional evidence that burnout may be contagious within professional communities via the crossover effect, referring to an inter-individual transmission of stress or strain. However, our understanding of effective means for tackling stressors is scarce. We tested a two-level path model to explore the interrelation between teachers’ proactive self- and co-regulative strategies and experienced burnout. The study sample comprised 1531 Finnish in-service teachers from 75 schools. The results showed that burnout symptoms varied both between individual teachers and between professional communities. Self- and co-regulative strategies serve partly different functions in regulating teach…
