No full textSlovenski komorni zbor, ki se je leta 2015 preimenoval v Zbor Slovenske filharmonije, je v začetku marca 2016 praznoval 25-letnico delovanja. V svoji zgodovini se lahko pohvali z zavidljivimi dosežki, nepozabnimi dogodki in repertoarjem, katerega arhivska evidenca je že presegla število 3000.
Zbor je oživil in posnel dobršen del slovenske zborovske zapuščine in izvedel številne novitete tako slovenskih kot tujih skladateljev. Vrsto skladb iz svetovne zborovske zakladnice je v Ljubljani predstavil prvi.
Sodeloval je z eminentnimi glasbeniki z vsega sveta, med njimi so Eric Ericson, Tõnu Kaljuste, Stephen Layton, Kaspars Putninš, Riccardo Muti, Mariss Jansons, Valerij Gergijev, sir Nevill Marriner, Hartmut Haenchen in Ana Netrebko.
Zbor redno prireja koncerte v okviru Vokalnega abonmaja, koncertira po Sloveniji in Evropi, kot oratorijski zbor nastopa v abonmajih Orkestra Slovenske filharmonije in gostuje pri drugih orkestrih doma in na tujem. Je prejemnik številnih nagrad, največkrat na Hrvaškem, kjer je bil reden gost na Varaždinskih baročnih večerih in snemal hrvaško zborovsko antologijo. K tem uspehom so Slovenski komorni zbor vodili njegov ustanovitelj Mirko Cuderman, za njim pa Steffen Schreyer in Martina Batič, ki je njegova umetniška vodja še danes. Skupaj z zborom stremi k doseganju najvišjih kriterijev in uresničevanju poslanstva, ki mu je bilo zaupano pred 25 leti.Slovenian Chamber Choir, renamed Slovenian Philharmonic Choir in 2015, celebrated its 25th anniversary in March 2016.

INFLUENCE OF THE CAST IRON’S CHEMICAL COMPOSITION ON THE INTERPHASE DISTRIBUTION OF CR AFTER ANNEALING AT 690 °C
No full textPurpose. The article is aimed to determine effect of the chemical composition of Fe-C-Cr-Mn-Ni cast iron on the chromium content in the metallic base, carbides and the coefficient of interphase distribution of chromium after annealing at 690 ° С (КРСr690). Methodology. Cast irons containing 1.09–3.91% C; 11.43–25.57% Cr; 0.6–5.4% Mn; 0.19–3.01% Ni and 0.8–1.2% Si were investigated. The analysis of chromium distribution was carried out using mathematical statistics methods. Cast iron was melted in induction furnace with a capacity of 60 kg. Findings. The use of methods of active planning of the experiment 24-1 allowed us to establish regression dependencies of the chromium concentration in the base and carbides, as well as its interphase distribution coefficient on the С, Mn, Cr and Ni content in the cast iron. Chromium, after annealing, was mainly concentrated in carbides. The chromium content of the base varies from 3.94% at 3.23% C, 5.4% Mn, 11.43% Cr and 3.01% Ni to 17.43% at 1.09% C, 0.60% Mn, 25.57% Cr and 1.32% Ni. The minimum value of the distribution coefficient of CRC690 was 2.1 in cast iron, of composition 1.09% C, 0.6% Mn, 11.43% Cr and 0.19% Ni, maximum 9.4 at 3.91% C, 0, 6% Mn, 11.43% Cr and 3.01% Ni. The distribution of chromium was determined by the amount and type of carbides formed. During annealing, the carbides’ composition was formed as a result of carbide-forming elements contention and replacement of iron and manganese atoms by chromium atoms. Originality. Authors obtained regression dependences of the chromium content in the base, carbides and its interfacial distribution coefficient on the chemical composition of Fe-C-Cr-Mn-Ni cast iron after annealing at 690 ° C. Practical value. The obtained dependencies allow predicting the chromium content in the metallic base and may be used during the elaboration of the new wear resistant cast irons compositions, as well as in the choice of heat treatment regimes
THE INFLUENCE OF CHEMICAL COMPOSITION ON THE CORROSION RATE OF HIGH-CHROMIUM CAST IRON
No full textThe influence of the chemical composition on the corrosion rate of high-chromium cast iron was researched. During the castings’ cooling process the replacement of the atoms of nickel, iron and manganese by the atoms of chromium in the carbides took place. As a result, the areas with reduced chromium content were formed near carbides. After decreasing the chromium content in these areas below 12% the corrosion processes activated. Using the mathematical experimental design techniques the regression dependence between the corrosion rate of the cast irons and content of C, Cr, Mn and Ni in them was established. The conducted research showed that the minimum corrosion rate was observed in the cast iron containing: 1.09% C, 25.57% Cr, 0.6% Mn and 1.87% Ni. The obtained results allow predicting the corrosion rate of the high-chromium cast irons alloyed with Mn and Ni and may be used while establishing the new compositions of wear-resistant materials
INFLUENCE OF THE CAST IRON’S CHEMICAL COMPOSITION ON THE CONTENT OF CR IN THE BASE AFTER NORMALIZATION FROM 1050 C
No full textThe dependences of the influence of the chemical composition of cast iron in the Fe-Cr-Mn-Ni system on the chromium cotent in the metal base (Cr1050о) and carbides (Cr1050Cr) after normalization from 1050 °C with aging for 4.5 hours were established. During the heat treatment of the castings, a redistribution of the elements between the phases of the cast iron occurred. The maximum chromium concentration in the base after normalization was 19.7% at 1.09% C, 3.1% Mn, 25.5% Cr and 0.19% Ni, and the minimum 2.4% at 3.91% C, 0.6% Mn, 11.43% Cr and 0.19% Ni. The maximum amount of chromium in carbides 78.4% was observed in cast iron containing 1.09% C, 5.4% Mn, 3.01% Ni and 25.57% Cr, and the minimum 43.5% at 3.59% C, 5.4% Mn, 3.01% N and11.43% Cr. The obtained dependencies allow predicting the chromium content in the metallic base and can be used during the elaboration of new compositions for wear-resistant cast iron, as well as at choice of heat treatment regimes
INFLUENCE OF THE CAST IRON’S CHEMICAL COMPOSITION ON THE INTERPHASE DISTRIBUTION OF MN
No full textPurpose. This paper focuses on obtaining the dependencies of the manganese content in the metallic base (Mno) and its interphase distribution coefficient (KPMn) on the cast iron’s chemical composition in the system Fe–C–Cr – Ni –Mn. Methodology. The cast irons containing 1.09…3.91% С, 0.6…5.4 % Mn, 11.43…25.57 % Crand 0.19…3.01 % Ni have been studied. The active experiment design techniques were applied to build a mathematical model of manganese distribution. Cast iron was smelted in the induction furnace with the capacity of 60 kg, with basic lining.Findings.Manganese, being a carbide-forming element, distributed between carbides and the metallic base. With the use of the mathematical statistics methods, regression dependencies of the manganese concentration in the base and its interphase distribution coefficient on the С, Mn, Cr and Ni content in the cast iron were established. The manganese concentration in the base varied from 0.37 % at 1.09 % С, 0.6 % Mn, 11.43 % Cr and 3.01 % Ni to 5.79 % at1.09% С, 5.4 % Mn, 25.57 % Cr and 0.19 % Ni. The minimum value of the interphase distribution coefficient was 0.16 in the cast iron containing 1.09 % С, 0.6 % Mn, 25.57 % Cr and 3.01 % Ni. When the КРMn coefficient values were lower than 1, manganese concentrated predominantly in the metallic base. The maximum value of the КРMn coefficient was 2.48 at 3.91 % С, 0.6 % Mn, 11.43 % Cr and 0.19 % Ni. The manganese distribution pattern was determined by the carbides’ quantity and chromium and carbon ratio that determined the carbide type. The carbides’ composition was formed as a result of carbide-forming elements contention. Originality. Regression dependencies of the manganese content in the base and its interphase distribution coefficient on the cast iron’s chemical composition in the system Fe–C–Cr – Ni –Mn have been obtained. The dependency of the manganese distribution on the carbide forming processes has been established. Practical value. The obtained dependencies allow predicting the manganese content in the metallic base and may be used during the elaboration of the new wear resistant cast irons compositions
Morte, música e sexualidade na Ópera Turandot de Puccini
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.Esta dissertação pretende ser uma análise multiangular da ópera Turandot, de Giacomo Puccini (1858-1924). Deixada incompleta pelo compositor e encenada pela primeira vez em 1926, esta ópera é vista pelos musicólogos William Ashbrook e Harold Powers como marco do fim da grande tradição operística da Itália. O trabalho considera o entrelaçamento das convenções musicais e das convenções discursivas da partitura músico-textual de Turandot, a fim de esclarecer como analogias, referências e contradições musicais podem contribuir para a eficácia da narrativa verbal. O estudo de Turandot levou à reflexão da ópera como gênero e a dissertação está organizada pela gradual exploração das camadas da obra, da mais externa, a ópera em geral, até a reflexão sobre a psicologia de suas personagens, passando pela influência mútua entre música e narrativa nas idiossincrasias de Turandot como construção músico-literária singular. This paper intends to be an analysis from many angles of the opera Turandot, by Giacomo Puccini (1858-1924). Left incomplete by its composer and taken to the stage for the first time in 1926, this opera is regarded by musicologists William Ashbrook and Harold Powers as the ending of Italy's great operatic tradition. This work considers the intertwining of musical and speech conventions from Turandot's musical and textual score, with the objective of clarifying how musical analogies, references and contradictions may contribute to verbal narrative's effectiveness. The analysis of Turandot led to the reflection of opera as genre, so the paper is organized according to the gradual exploring of that opera's layers, from the most external - that is, the opera in general - to the reflection over its characters' psychology, passing by the mutual influence between music and narrative in Turandot's idiosyncrasies as a musical-literary unique construction
