Study of phase transition in Bi3TiNbO9-BaBi2Nb2O9 ceramics
2016
Abstract The subject of the paper is lead free bismuth layer structure oxides (1-x)Bi3TiNbO9-xBaBi2Nb2O9 (x=0; 1; 2; 3 mol). The influence of Bi3TiNbO9/BaBi2Nb2O9 ratio on dielectric and structural properties was studied in a wide range of temperatures. Change in the ratio causes a decrease in the maximum value of dielectric permittivity and shifts the temperature of ε’max to low values, leading to linear decreasing of average grain size and linear increasing of ceramics density. These results indicate an augment of the packing degree and the participation of pores are significantly decreased with the increase of BaBi2Nb2O9 compound intake. Moreover, for 0.7Bi3TiNbO9-0.3BaBi2Nb2O9 ceramics …
Design and development of safety and control systems in ATLAS
2021
El gran colisionador de hadrones, o LHC, es el acelerador de partículas más grande y potente del mundo. Ha sido construido por el CERN, la Organización Europea para la Investigación Nuclear, entre 1998 y 2008 en Ginebra, Suiza. Sucesivas mejoras en el LHC supondrán a partir de mediados del 2027 un incremento de la luminosidad, cuando pasará a llamarse High Luminosity LHC (HL-LHC). Esta tesis se divide en dos partes, por una parte la seguridad y operación de la infraestructura y por otra los sistemas de control y toma de datos. La primera parte de la tesis se dedica a la seguridad y operación de la infraestructura. Después de más de 10 años de funcionamiento, el riesgo de posibles fallos en …
Towards the Learning Experience Technology Usability framework
2017
The availability of learning technology has increased over past decades; however, severe usability issues that cause adverse effects on the learning experience can be found in many available technologies. Learning solution usability is commonly evaluated by focusing on either technical or pedagogical usability and rarely both. This artificially separates the two important aspects of learning technology usability. This chapter provides a new framework for designing and evaluating learning solutions that synthesizes the above usability types to consider them a part of a complex and dynamic whole comprising of learning, technological design, content-related issues and context. The proposed Lea…
The dynamics of expertise acquisition in sport: The role of affective learning design
2015
Objectives: The aim of this position paper is to discuss the role of affect in designing learning experiences to enhance expertise acquisition in sport. The design of learning environments and athlete development programmes are predicated on the successful sampling and simulation of competitive performance conditions during practice. This premise is captured by the concept of representative learning design, founded on an ecological dynamics approach to developing skill in sport, and based on the individual-environment relationship. In this paper we discuss how the effective development of expertise in sport could be enhanced by the consideration of affective constraints in the representativ…
Prevalence of left ventricular hypertrophy in children and young people with primary hypertension: Meta-analysis and meta-regression
2022
BackgroundLeft ventricular hypertrophy (LVH) is the main marker of HMOD in children and young people (CYP). We aimed to assess the prevalence of LVH and its determinants in CYP with primary hypertension (PH).MethodsA meta-analysis of prevalence was performed. A literature search of articles reporting LVH in CYP with PH was conducted in Medline, Embase, and Cochrane databases. Studies with a primary focus on CYP (up to 21 years) with PH were included. Meta-regression was used to analyze factors explaining observed heterogeneity.ResultsThe search yielded a total of 2,200 articles, 153 of those underwent full-text review, and 47 reports were included. The reports evaluated 51 study cohorts inc…
Jurisdiction in cases of divorce, legal separation or marriage annulment
2021
The subject of coordination is fundamental for the functioning of jurisdictional rules of the Regulation n.2016/1103 on matrimonial property regimes and Regulation n.2016/1104 on the property consequences of registered partnerships. Both Property Regimes Regulations have the purpose of gathering litigation before the courts of one Member State and have the related procedures managed by the courts of the same Member State. Recital 34 of Regulation No. 2016/1103 specifies that matters of matrimonial property regime related to proceedings pending before the court of a member state hearing an application for divorce, legal separation or marriage annulment should be dealt with by the courts of t…
Liecības un eksperta atzinums kriminālprocesā
2015
Maģistra darbā „Liecības un eksperta atzinums kriminālprocesā” tiek apskatīta pierādījumu rašanās paralēli ar kriminālprocesa attīstību pasaulē. Tiek norādīti Latvijā pieļaujamie pierādījumu veidi, papildus atsevišķi aprakstot tieši liecības un eksperta atzinumu. Tiek norādītas arī konkrētas situācijas, kad esošais normatīvais regulējums rada problēmas vai pārkāpumus liecību un eksperta atzinuma piemērošanā. Pamatojoties uz darbā norādītajiem apskatītajiem Latvijas tiesību aktiem, Latvijas tiesu un Eiropas cilvēktiesību tiesas izdarītajiem secinājumiem, tiek sniegti priekšlikumi liecību un eksperta atzinuma normatīvā regulējuma uzlabošanai Latvijā, piemēram, papildus liecību nolasīšas kritē…
State of the art and prospects for halide perovskite nanocrystals
2021
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics and photocatalysis. The ease with which metal-halide perovskites can be synthesized in the form of brightly luminescent colloidal nanocrystals, as well as their tunable and intriguing optical and electronic properties, has attracted researchers from different disciplines of science and technology. In the last few years, there has been a significant progress in the shape-controlled synthesis of …
Ulomman reisilihaksen poikkipinta-alan kasvu 21 viikon voimaharjoittelujakson aikana harjoittelemattomilla 19-34 -vuotiailla miehillä : eri lihassolu…

Salmijärvi, Hanna 2008. Ulomman reisilihaksen poikkipinta-alan kasvu 21 viikon voimaharjoittelujakson aikana harjoittelemattomilla 19–34 vuotiailla miehillä; eri lihassolutyyppien vaikutus poikkipinta-alan kasvuun. Valmennus- ja testausopin kandidaatin tutkielma. Jyväskylän yliopisto. Liikuntabiologian laitos, 36s. Voimaharjoittelu harjoittelemattomilla saa ensin aikaan nopeaa voimatason nousua, mutta lihasten kasvua eli hypertrofiaa voidaan kuvantamismenetelmillä havaita vasta 16 harjoituksen jälkeen. Tyypin I lihassoluilla on kyky vastustaa väsymystä, mutta niiden voimantuotto on melko pientä. Tyypin IIa lihassolut ovat hyvin väsymystä vastustavia ja niiden voimantuotto on suurta. Tyypin …
