Steel fibers recovered from recycled tires were considered for use as reinforcement in concrete to improve the tensile properties of concrete as well as being an economically viable and environmentally friendly alternative. This paper investigates the effect of purified and non-purified recycled tire steel fiber in concrete with a constant fiber proportion of 30 kg m−3 to determine properties in fresh and hardened concrete. The results indicate that concrete with purified tire fibers have better tensile properties than those with non-purified tire fibers. Density, strength, and toughness significantly increase but workability tends to decrease when using recycled tire steel fiber as reinforcement in concrete.

In this article, two important newspapers of the Habsburg monarchy – the Wiener Zeitung (previously: Wien[n]erisches Diarium) and the Preßburger Zeitung – are related to each other in several aspects. After a historical overview of the context in which these periodicals were created and taking into account the research literature already available, the first step was to look for parallels in their formal design. Since both newspapers have also been digitally made accessible in full text recently, it was also possible to determine approximately how frequent direct mutual references to the other periodical occur by means of so-called distant reading procedures. Close reading methods were then used to examine and interpret the corpus-based references. This comparative approach with digital methods allows the synoptic examination of individual text passages and thus offers new insights into the complex relationship between the Wiener Zeitung and the Preßburger Zeitung in the 18th century.
The phenomenon of transculturalism is capable of activating and generating meaning within various spaces, levels and layers of literature. The study discusses different levels of transculturalism through certain authors and texts in Slovakian Hungarian literature, along with transcultural authorial identity, the transcultural meaning-making machinery of texts, transcultural practices of the social context, and transcultural directions and gaps in reception. The purpose of the paper is to classify some of the transcultural phenomena we encounter and to unravel the relevant conceptual and interpretative levels.
The history of American-Hungarian relations has enjoyed renewed interest in the past thirty years. Despite this fact, there are still many uncovered or poorly documented episodes and persons concerning this academic territory. This article wishes to shed some light on one such character and period. It was in 1922 that the United States and Hungary established official diplomatic relations for the first time. Consequently the two countries exchanged ministers; thus, a long line of American ministers began to come and reside in Hungary. The very first of them was Theodore Brentano, who served five years in Budapest, between 1922 and 1927, but who seems to have disappeared from historical memory in both countries. Since 2022 marks the centenary of establishing diplomatic relations between the two countries, this article will introduce Theodore Brentano, the first American minister for Hungary and his work there. Brentano's years coincided with momentous events in Hungary in the post-Trianon era and were a time of relatively active relations between Washington and Budapest. Using primary and secondary sources alike, this article will hopefully illustrate a sorely missed part of the history of American-Hungarian history and rekindle interest in what took place a century ago.
In realizational theories of morphology, different opinions exist on the relationship between phonology and Vocabulary Insertion. On the one hand, there are separational theories like Distributed Morphology (Halle & Marantz 1993), which assume that Vocabulary Insertion does not interact with the phonological component of the grammar. These theories predict that the properties of a language's regular phonology never play a role when vocabulary items (VIs) are inserted. The opposite view is held by integrational theories as, for instance, proposed in Wolf (2008). These theories assume that the general phonology of a language can influence Vocabulary Insertion. Based on adjectival agreement in the language Vata, I propose an integrational model that assumes that Vocabulary Insertion applies in an Optimality-Theoretic (Prince & Smolensky 1993) phonology, where regular phonological constraints are active. I propose that the phonology consists of two levels: one level where VIs are inserted and one level for regular phonology.
The subject of this contribution is Alexander/Sándor Albrecht’s musical output from the 1920s in the context of the development of the composer’s musical style, his life and the social and political changes in Bratislava after 1918. Albrecht returned to Pressburg/Pozsony in 1908 after his studies in Budapest and devoted his organisational and artistic activity to the city; in 1921 he became the conductor at the Kirchenmusikverein (until 1952), a traditional music institution of the city. In 1920s Albrecht also achieved the creation of his own musical style. Coming out from a base of late Romanticism, Albrecht applied in that time the modernistic principles to his œuvre. In 1924 he wrote his mature Piano Suite, and in 1926 his Sonatina for 11 Instruments, an interesting piece of well-balanced formal and harmonic innovations, and one of the first pieces for chamber ensemble (after Schoenberg’s Kammersinfonie) in the Central European context. In 1929 Albrecht’s oratorio-like Marienleben: Three Poems after R. M. Rilke for soprano, mixed chorus and orchestra was successfully premiered. The present study contains detailed analyses of these three pieces, which are the most outstanding and distinctive works by the composer.
The paper deals with the first recording of Richard Strauss’s tone poem Don Juan, of which the first half (i.e. the first two of a total four sides of this 1916 78-rpm recording) has repeatedly been said to be conducted not by Richard Strauss, but by George Szell who served as Strauss’s assistant at the Berlin court opera at that time. By a close examination of written accounts, I wish to clarify the background of this narrative which Peter Morse, somehow misleadingly, has called an “old story” as early as in 1977, though it seems that it was not given currency prior to the late 1960s when Szell himself mentioned the recording en passant during an interview. In a second step, comparative analyses of certain sections from both this 1916 and Strauss’s later recordings of Don Juan will not only proof Szell’s participation, but aim at determining the respective interpretational concepts in their differing performance choices. Finally, further comparison between Szell’s later Don Juan recordings (1943, 1957, 1969) and selected performances by contemporary conductors intends to help situate Szell within the Austro-German Espressivo tradition, whereby the detailed analysis of tempo-dramaturgical strategies in these recordings will itself contribute to a differentiation of the frequently simplified notion of “Espressivo.”

This study establishes a method for rapid detection of clonidine and cyproheptadine in foods of animal origin. In order to obtain the best detection method, capillary zone electrophoresis (CZE), large volume sample stacking (LVSS), and sweeping-micellar electrokinetic capillary chromatography (sweeping-MEKC) were used respectively. The limits of detection (LODs) of clonidine and cyproheptadine by LVSS-CZE were 0.028 μg mL−1 and 0.034 μg mL−1, and those by sweeping-MEKC were 0.023 μg mL−1 and 0.031 μg mL−1, respectively. Compared with the CZE method, the two online pre-concentration technologies have greatly improved the detection sensitivity and achieved good enrichment results. However, compared with the sweeping-MEKC system, the LVSS system consumed a longer time and was greatly affected by the actual sample matrix. The sweeping-MEKC method was proved to be suitable for real sample analysis. Under the best sweeping-MEKC conditions, clonidine and cyproheptadine could be well separated within 8 min and good linear relationships in the range of 0.1–1.0 μg mL−1 (r2 > 0.99) were obtained. This method was successfully applied to the determination of clonidine and cyproheptadine in animal-derived foods with the recoveries of 82.3%–90.1% and the relative standard deviations (RSDs) less than 3.11%. The sweeping-MEKC method is simple to operate and has great potential in the rapid detection of clonidine and cyproheptadine in animal-derived foods.
Taiwan government consolidated the kindergarten and daycare systems in 2012, and launched a new national curriculum framework, Early Childhood Education & Care Curriculum Framework (ECECCF), as a guidance for quality early childhood education programs. Research has shown that the effects of a new educational program highly depended on the fidelity of its implementation. It has thus been suggested that the degree of implantation of a program needs be evaluated before conducting further program evaluation.
Thus, the purpose of this study was to construct an Early Childhood Education Curriculum Framework Implementation Scale (ECECCF Implementation Scale) for Taiwanese preschool programs. 216 preschool classes in Taiwan were involved. The study consisted of two stages: In Stage 1, the exploratory factor analysis showed that the implementation of ECECCF could mostly be explained by four factors, and all the factors extracted had acceptable reliability and validity. In Stage 2, rubrics were constructed for each item and factor analysis was re-conducted, resulting in a 19-item scale of four factors (Awareness and Adjustment, Learning Centers Arrangement, Teaching Guidance and Curriculum Development). The reliability and validity tests shows that: (1) the final version of the ECECCF Implementation Scale is a valid and reliable instrument, explaining 62.9% of the total variance; (2) the criterion validity indicated that the ECECCF scale can not only be used for assessing the implementation of ECECCF, but also can be used for understanding teachers’ needs in instructional and operational curriculum for further professional development.
