THE MUSICAL-DRAMATURGIC CONCEPT OF THE MONOOPERA ATEH BY GH. CIOBANU IN CORRELATION WITH THE LITERARY SOURCE
No full textThe article is devoted to the peculiarities of the musical embodiment of the literary source in the mono-opera-ballet „Ateh or the revelations of the Khazar princess” by Gh. Ciobanu, based on three fragments from the lexicon-novel „Dictionary of the Khazars” by M. Pavic, a reference work of art of the end of the 20th century. Following from the genre characteristics of modern mono-operas, on the one hand, and on the exceptional qualities of Ateh’s image in the novel, on the other hand, the author reveals the basic principles of the composer’s approach to the literary text — selectivity, economy of verbal means, simplification of the content plan by eliminating the text with symbolic and mystical components and increasing the role of musical-dramatic means. The author considers various types of semantic relation between the text and music in the mono-opera — convergence (illustration, parallelism, association and others) and divergence of meanings. The author comes to the conclusion that the semantic concepts of the monoopera by Gh. Ciobanu occur at the intersection of the self-reflection principle, on the one hand, on the other hand — of the idea of transformations that moves the musical-dramaturgical process

In: Simpozion Ştiinţific al Tinerilor Cercetători, (8-9 aprilie 2022) [online]: Culegere de lucrări ştiinţifice. Ediţia a 20-a. Chişinău: ASEM, 2022, vol. 1, pp. 191-194. ISBN 978-9975-3590-2-3 (PDF).This article presents the profit analysis and it was made based on the data of the financial statements of ,,Franzeluța” SA, 2019-2020. As methodological support of the investigation will serve the dialectical method of knowledge with its components: analysis, synthesis, deduction, observation, comparison, selection, grouping and scientific abstraction. As documents, I used the Financial Statements, National Accounting Standards(SNC), and a book, called ,, Analiza Rapoartelor Financiare”and as a source of information, I used the search engine, Google. Based on the profit and loss analysis, the author calculated the absolute deviation of the profit in comparison with the previous year and commented with subsequent conclusions. Consequently, the author found that in 2020 ,,Franzeluța”S.A presented a lower value of the profit, which has a negative impact on the economic activity of ,,Franzeluța”S.A. This problems could be solved with new development strategies and with an efficient organization of the company’s activity.

Sol-gel treatments on cotton fabrics for improving thermal and flame stability : effect of the structure of the alkoxysilane precursor
No full textSol-gel treatments have been performed on cotton fabrics in order to promote the formation of a surface silica insulating barrier, able to enhance their thermo-oxidative stability and flame retardancy. In particular, the role of several silica precursors, which differ as far as their structure (number and type of hydrolysable groups, presence of aromatic rings) is concerned, has been thoroughly investigated. The level of silica distribution and dispersion on and within the fabrics was found to depend on the type of precursor employed, as revealed by scanning electron microscopy and elemental analysis. All the precursors were able to favour the char formation in air below 360 °C, as stated by thermogravimetric analysis: in particular, the highest thermal stability was achieved in the presence of precursors bearing aromatic rings. Indeed, both flammability resistance and combustion behaviour of the treated fabrics were remarkably enhanced
Novel flame retardant finishing systems for cotton fabrics based on phosphorus-containing compounds and silica derived from sol-gel processes
No full textCotton fabrics have been subjected to sol-gel processes performed in the presence of phosphorus-based compounds, in order to prepare a novel flame retardant finishing system. The effect of the concurrent presence of phosphorus and silica on the flame retardancy and combustion behaviour of cotton has been assessed through flammability tests and cone calorimetry, respectively. Furthermore, the improved thermo-oxidative stability of the treated fabrics has been evaluated by thermogravimetric analysis in air. The obtained results have shown the efficiency of the novel flame retardant finishing system and its durability, as well
Cotton fabrics treated with hybrid organic-inorganic coatings obtained through dual-cure processes
No full textCotton fabrics were treated with a hybrid organic-inorganic coating obtained through a dual-cure process, i. e. a photopolymerization reaction followed by a thermal treatment for promoting the formation of silica phases through a sol-gel process. To this aim, different amounts of a silica precursor were added to an acrylic UV-curable formulation in the presence of a suitable coupling agent. The thermo-mechanical properties of the treated fabrics were investigated and correlated to the composition and morphology of the hybrid organic-inorganic system. Furthermore, their flame retardancy and combustion behavior were evaluated by flammability tests and cone calorimetry and compared with the performances of pure cotton
Thermal stability, flame retardancy and mechanical properties of cotton fabrics treated with inorganic coatings synthesized through sol-gel processes
No full textCotton was sol-gel treated employing several metal alkoxide precursors (namely, tetraethylortho-silicate, -titanate, -zirconate and aluminium isopropylate) in order to get inorganic phases able to improve the thermal stability and flame retardancy of the fabric, without changing its mechanical features. Indeed, after the sol-gel treatment the fibre/fabric surface was morphologically modified: a homogeneous and compact film located in the fibre interstices (warp and weft) and partially covering their walls was observed for all the systems investigated. These coatings turned out to be responsible of an overall enhancement of the thermal and fire stability of the fabrics preserving, at the same time, the original mechanical properties of the neat cotton in terms of tensile strength and deformation. In addition, such inorganic coatings increased the abrasion resistance of the cotton in a remarkable way
Sol-gel treatments for enhancing flame retardancy and thermal stability of cotton fabrics: optimisation of the process and evaluation of the durability
No full textCotton fabrics have been treated by sol-gel processes in order to create a silica compact coating on the fibres to enhance their thermal stability and flame retardancy. The effect of process parameters such as silica precursor:water molar ratio and drying conditions (temperature and time) has been thoroughly investigated, aiming at optimization of target properties. Thermogravimetry and cone calorimetry have been respectively used to assess thermal stability and combustion behaviour of treated fabrics. Coating durability to different washing programmes has been evaluated as well
