Authors: A. Alzubaidy Ayad , M. K. Nissan Layth 
Published: January 2025

Background: This review aims to assess the enamel surface roughness change following brackets debonding and adhesive cleaning using two types of adhesive removal burs with and without wearing dental loupes. Material and Methods: Eighty human premolars were extracted before starting orthodontic treatment and used as the samples for the current study. All samples were attached with metal brackets and then divided at random into four groups (n=20) by wearing Loupes and using tungsten carbide bur (LT), wearing Loupes and using stainbuster bur (LS), using tungsten carbide bur without wearing loupes (WLT) and using stainbuster bur without wearing loupes (WLS). All groups were subjected to these methods by using low-speed handpiece. Enamel surface roughness (ESR) measurements were done using Stylus Profilometry (Surface roughness tester Time®3200) as (R1) before the bonding time point and (R2) after the adhesive cleaning time point.
Results: The outcomes were statistically analyzed via the Independent T-test (P ≤ 0.05). The results displayed statistically considerable differences between the resin cleaning methods related to enamel surface roughness by wearing loupes or not and using tungsten carbide or stainbuster burs. Conclusion: Wearing dental loupes during the debonding procedure could improve the quality of the adhesive removal technique. In addition, a stainbuster burs system showed a better adhesive removal method than tungsten carbide bur.

Published: January 2025

В статье рассматривается хоровой концерт «Печальные песни» современного композитора Валерия Васильевича Пьянкова (1940 г.р.), написанный на стихотворения Александра Блока. Произведение создавалось во второй половине 80-х годов ХХ века и явилось своего рода, реакцией, эмоциональным откликом музыканта на происходящие кардинальные перемены в жизни родного государства. Концерт состоит из одиннадцати хоров, названия которых соответствуют названиям блоковских произведений, написанных с 1905 по 1914 годы. Первые четыре хора повествуют о тревогах и лишениях после революции 1917 года в России. Три средних хора - это картины России, средневековой Европы, Испании. Последние четыре хора выражают стремление к христианским идеалам, к духовному Возрождению. В статье осваивается малоизученный в отечественном музыкознании материал, что обусловливает актуальность и научную новизну исследования. Цель работы - расширить представления музыкальной науки об отечественной хоровой музыке последних десятилетий, в частности о сочинениях для хора Валерия Пьянкова.
The article examines the choral concert «Sad Songs» by the modern composer Valery Vasilyevich Pyankov (born in 1940), written on poems by Alexander Blok. The work was created in the second half of the 80s of the twentieth century and was a kind of reaction, an emotional response of the musician to the cardinal changes taking place in the life of his native state. The concert consists of eleven choirs, the names of which correspond to the names of Blok's works created from 1905 to 1914. The first four choirs tell about the anxieties and hardships after the 1917 revolution in Russia. The three middle choirs are paintings of Russia, medieval Europe, and Spain. The last four choirs express the desire for Christian ideals, for spiritual Rebirth. The article examines the little-studied material in Russian musicology, which determines the relevance and scientific novelty of the study. The aim of the work is to expand the understanding of musical science about the Russian choral music of recent decades, in particular about the compositions for the choir by Valery Pyankov.

Published: January 2025

В статье исследуется роль фортепианного аккомпанемента как средства драматургии и эмоциональной выразительности в вокальном цикле Роберта Шумана. Рассматривается, как романтический аккомпанемент может выходить за рамки простой поддержки вокальной линии и становиться полноценным участником музыкального повествования. На примере цикла песен Шумана "Любовь поэта" раскрываются способы передачи сложных эмоциональных состояний посредством изменения в ритме, фактуре, тембре и динамике фортепианной партии. При этом акцентируется внимание на взаимосвязи музыкальных и поэтических элементов, углубляющей драматизм и эмоциональную напряженность произведений.
The article explores the role of piano accompaniment as a means of emotional expression in Romantic songs, with a special focus on the work of Robert Schumann. It considers how accompaniment can go beyond mere support of the vocal line and become a full-fledged participant in the musical narrative. Using the example of Schumann's song cycle "The Poet's Love", it reveals the ways in which complex emotional states can be conveyed through changes in the rhythm, timbre and dynamics of piano parts. The study also emphasizes the interrelation of musical and poetic elements that deepen the drama and emotional tension of the works.

The Faina gold deposit, located in the Pitangui Greenstone Belt, NW of the Quadrilátero Ferrífero, Brazil, has produced gold from the oxidized portion of the deposit between June 2010 and June 2013. However, the deeper hypogene (sulfide-rich) section of the deposit has shown lower-than-expected recovery rates after direct leaching, leading to the interruption of gold production. This research presents a multi-methodological approach (drill core description, multi-element geochemical analyses and mineral characterization using microscopy and X-ray diffraction) to investigate describe the Faina gold deposit and identify the cause of low recoveries from the hypogene zone. The stratigraphy at Faina consists of a sequence of meta-mafic and meta-sedimentary rocks, with a thick (>40m) saprolite horizon (oxidized portion). Both the meta-mafic rocks and saprolite host gold mineralization, which is identified by distinct geochemical and mineral signatures: 1) Au-As-W in the hypogene zone, with gold associated with sulfides or as disseminations in silicates and 2) Au-As-W in the oxide-rich shallower section with free-milling gold associated with quartz, iron oxide-hydroxides and clay minerals. Geochemical, mineral and textural relationships in the hypogene zone show that submicroscopic gold particles associated with minerals, that consume leaching solution minerals (arsenopyrite, pyrrhotite and berthierite) may cause refractoriness during direct leaching. Separation of gold from these mineral phases, in addition to concentration methods during ore processing may increase gold recovery. The results presented in this research emphasize the importance of a detailed geochemical and mineral characterization to reveal the contrasting mineral and chemical compositions between hypogene and oxidized zone, which may influence gold recovery.

Published: January 2025

This article explores the dynamics of Turkism usage in the English language, leveraging Google Ngram data to analyze historical and contemporary trends. It investigates the origins, dissemination, and impact of these borrowings, which arose from cultural exchanges, trade routes, and historical interactions between Turkic peoples and English-speaking communities. Turkisms are categorized into several domains: toponyms (e.g., Caspian Sea, Khiva), terms related to social structures and titles (e.g., khan, bey), culinary terms (e.g., kebab, yogurt), and others. The study examines their etymology, semantic transformations, and roles in enriching the English lexicon, reflecting the significance of linguistic and cultural connections over centuries. The research employs a multidisciplinary approach, combining statistical analysis using Google Ngram with historical and sociolinguistic perspectives. It identifies patterns in the integration of Turkisms, highlighting their persistence and adaptability within the English language. Key findings reveal how these borrowings have become deeply embedded in various aspects of English vocabulary, symbolizing cultural interaction and historical ties. Examples such as "kebab" and "yurt" illustrate the influence of Turkic traditions on global linguistic systems, particularly in areas such as cuisine, geography, and governance. The article emphasizes the importance of further studies on borrowings to better understand their contributions to the development of global languages. It concludes that Turkisms are not only markers of historical and cultural exchange but also play an ongoing role in shaping linguistic identity in the context of globalization.
Including Historic Maps in School Atlases: Potential and Limitations
Authors: HEGYESI Dóra 
Published: January 2025

Ever since printing allowed the mass distribution of documents, we have accumulated an abundance of historic maps. These mapsallow for the thorough analysis of spatial processes, taking the changes of historical context into consideration. However, these resources are rarely included in school atlases, thus these mainly show the contemporary state of our environment. This study aims to explore the differences and similarities between the atlas design of Hungary, where history and geography are taught separately; and France, where these subjects are taught as one synthetizing subject. The primary focus is on the inclusion (or rather omission) of historic maps in these publications. Nonetheless, some other interesting approaches in atlas structure and design could be explored throughout the document analysis process.

Published: January 2025

A földmérési gyakorlatban már több évtizede használjuk a permanens GNSS-állomásokat a nagy pontosságú helymeghatározási feladatainkhoz. Ismeretes, hogy a GNSS-észlelések alapvető mérési eredménye, a műhold–vevő távolság számos szabályos hibával terhelt. A pálya és órahibák mellett a jelterjedéshez kapcsolódó hibák, különösen az ionoszféra és a troposzféra sebességmódosító hatása terheli még a permanens állomások méréseit is. Megfelelő feldolgozási eljárással a troposzférikus késleltetés kivételével ezen hibák jelentős része kiküszöbölhető vagy hatásuk jelentősen csökkenthető. Az állomások koordinátáinak ismeretében azonban lehetőségünk nyílik a műhold–vevő távolságokat terhelő troposzférikus hatások meghatározására.A troposzférikus hatások egyik összetevője a légköri vízpára mennyiségével áll kapcsolatban. Mivel a műhold–vevő vektorok a légkört számos helyen és különböző irányokban metszik, a számítógépes tomográfia eljárását alkalmazva a légköri vízpára térbeli eloszlására vonatkozóan nyerhetünk információt.Cikkünkben egy olyan GNSS-feldolgozórendszert mutatunk be, amellyel óránként határozzuk meg a Kárpát-medencében a légköri vízgőzsűrűség térbeli eloszlását. Eredményeinket több rádiószonda-állomás észleléseivel vetjük össze. Az eredmények alapján látható, hogy a GNSS-adatokból nem csak a vertikálisan integrált vízgőztartalomra, hanem annak térbeli eloszlására vonatkozóan isnyerhetünk információt a GNSS-adatok feldolgozásával, ami új távlatokat nyithat meg a GNSS-észlelések meteorológiai felhasználásaterén.
