Opera for children and analysis of Iztok Kocen\u27s opera Veveriček posebne sorte
No full textMagistrsko delo vključuje zgodovinski pregled opere kot glasbene oblike, njenih značilnosti in razvoj skozi čas. Opera je umeščena tudi v slovenski kulturni prostor s posebnim poudarkom na otroški operi, ki postaja pri nas vse pogostejši in pomemben del glasbene vzgoje otrok. Predstavljene so vidnejše opere za otroke slovenskih skladateljev, ki so nastale po letu 2000. Ključni del naloge je posvečen analizi otroške opere Veveriček posebne sorte. Za boljše razumevanje je vključena tudi zgodba pravljice Veveriček posebne sorte pisateljice Svetlane Makarovič ter življenjepis skladatelja, kar omogoča celovitejši vpogled v ozadje nastanka te opere. The master\u27s thesis includes a historical overview of opera as a musical form, its characteristics and development over time. It also places opera within the Slovenian cultural context, with a special focus on children\u27s opera, which is becoming increasingly common in Slovenia and plays an important role in children’s music education. The thesis presents notable children\u27s operas by Slovenian composers after the year 2000. The central part of the thesis is dedicated to the analysis of the children\u27s opera Veveriček posebne sorte. For a better understanding, it also includes the story Veveriček posebne sorte by the author Svetlana Makarovič, as well as the biography of the composer, providing a more comprehensive insight into the background of this opera\u27s creation
TRAFFIC EDUCATION OF PRESCHOOL CHILDREN
No full textPredšolski otroci so med najbolj ogroženimi udeleženci v prometu. Zato je potrebno z izvajanjem prometne vzgoje začeti že zelo zgodaj. S prometno vzgojo morajo otroka naprej seznaniti starši, saj so oni otrokov največji zgled.
V diplomskem delu je predstavljena prometna vzgoja in varnost ter izvajanje prometne vzgoje v družini in v vrtcu. Na podlagi anketnega vprašalnika pa so obdelani podatki o prometni vzgoji predšolskih otrok v vrtcu Dramlje. Iz podatkov je bilo razvidno, da starši svoje otroke dobro osveščajo, vendar bi bilo potrebnih še več srečanj za starše in vzgojitelje, da bi bili starši še bolj informirani o prometni vzgoji.Preschool children are among the most vulnerable road userstherefore, traffic education should be implemented at an early age. Parents are child\u27s greatest example this is why they should be the first one to inform their children about traffic education.
In this thesis the concept of traffic safety, traffic education, and its implementation in the family and in kindergartens are defined. Lastly, the author analysed the data of the questionnaire, which was given to the parents of preschool children in Dramlje kindergarten. The data showed that children are well informed about traffic safety by their parentshowever, there should be more meetings of parents and teachers in order to increase the knowledge of traffic education among parents
Tailoring Ink–Substrate Interactions via Thin Polymeric Layers for High-Resolution Printing
No full textStrain-induced ferroelectricity in KTaO
No full textThis paper has been formally withdrawn on ethical grounds because six of the co-authors listed (V. Bobnar, Z. Kutnjak, S. Glinšek, B. Kužnik, B. Malič, M. Kosec) had no knowledge or discussion of the content of the article,
nor had given permission for it to be submitted, nor had given approval for inclusion of their names as co-authors.
EPL submission policy states quite clearly that: “If several persons are listed as authors, the corresponding author takes full responsibility that the co-authors agree with the submission and further processing of the manuscript.” It is unfortunate that this misconduct was not detected before going to press. My thanks to the scientists named above
for bringing this fact to my attention.
Strain-induced ferroelectricity was observed directly at low temperatures in KTaO3 thin films and the temperature-strain phase diagram was determined. The values of εmax and Tmax of the ε′(T) curves change with the measuring electrical signal. The temperature dependence of the dielectric constant is fitted by the Curie-Weiss law
Percolative dielectric behavior of titanium carbide MXene/cellulose nanofibrils composite films
No full textCellulose-based nanomaterials are fascinating renewable biosystems, yet low thermal conductivity and dielectric permittivity often limit their potential applications in flexible electronics. We report dielectric properties of composite films prepared by vacuum filtration or solvent casting method from the native (CNF) or carboxylated (TCNF) cellulose nanofibrils and high electrically and thermally conductive 2D titanium carbide (Ti3C2Tx) MXenes. Measurements over broad frequency and temperature ranges revealed the influence of preparation method and type of nanofibrils matrix on the overall dielectric response, as well as a notable impact of absorbed water, particularly on the cellulose’s secondary β and γ relaxations. A detailed investigation of material with the lowest amount of impurities, vacuum-filtered MXene/CNF composites, confirmed that the dielectric response follows the predictions of the percolation theory. The resulting strong enhancement of the dielectric permittivity on increasing MXene content demonstrates the potential of developed composites for applications in eco-friendly dielectric and piezoelectric devices
Crossover from glassy to inho‐ mogeneous-ferroelectric nonlinear dielectric response in relaxor ferroelectrics
No full textThe temperature dependence of the dielectric nonlinearities in a PMN single crystal and in 9͞65͞35 PLZT ceramics has been determined by measuring the first and third harmonic response as well as the dielectric behavior as a function of the dc electric field. In zero field a paraelectric-to-glass, and, in a high enough dc field, a glass-to-ferroelectriclike crossover in the temperature dependence of the nonlinear response have been observed. Both crossovers agree with the predictions of the spherical random-bond -random-field model. Relaxors thus undergo in zero field a transition to a spherical glass, while above the critical field a transition into a ferroelectric state occurs. PACS numbers: 78.20.Ci, 77.84.Dy The nature of the diffuse phase transition in relaxor ferroelectrics, which are typically characterized by a broad frequency dispersion in the complex dielectric constant and slowing dynamics In a system with centrosymmetrical cubic symmetry the relation between polarization P and electric field E can be written as a power series P ͑´1 2 1͒E 2´3E 3 1 . . . . This can be inverted into E a 1 P 1 a 3 P 3 1 . . . , where a 1 1͑͞´1 2 1͒ and a 3 ´3͑͞´1 2 1͒ 4 ഠ´3͞´4 1 . The temperature dependence of the dielectric nonlinearity a 3 may, in principle, provide an answer to the open question about the nature of the relaxor freezing process. The scaling theory of the second order phase transition predicts that the nonlinear dielectric coefficient a 3 should vanish at the ferroelectric transition Very recently, it has been shown that the temperature dependence of the Edwards-Anderson order parameter q EA and the dielectric nonlinearity a 3 in lead magnesium niobate (PMN) can be well described by the spherical randombond-random-field (SRBRF) model It has been pointed out In order to resolve this controversy we have conducted high resolution measurements of the temperature dependence of the dielectric nonlinearities a 3 andâ 3 measured at various frequencies and dc electric bias fields in a broad temperature range. In this Letter, we report experimental data on the dielectric nonlinearities obtained in lanthanum-modified lead zirconate titanate ceramics Pb 12x La x ͑Zr y Ti 12y ͒ 12x͞4 O 3 with x 0.09 and y 0.65 (denoted as 9͞65͞35 PLZT) and in a PMN single crystal. We show that in agreement with some previous results The 0.52-mm-thick platelet of 9͞65͞35 PLZT hot pressed ceramics was covered with evaporated gold electrodes having surface dimensions of 4.7 3 3.5 mm 2 . In the case of the PMN single crystal, where electrodes and dimensions were prepared similarly as in the PLZT 5892 0031-9007͞00͞84(25)͞5892(4)$15.0
