Ludwig Senfl. “Maria Zart”: On the Problem of Composition Techniques Interaction
Authors: Тарасевич Н.И.
Published: May 2021

Музыкальное искусство Ренессанса представлено тремя важнейшими техниками — cantus floridus (c. fl.), cantus firmus (c. f.) и техникой сквозного имитационного письма. Каждая из них располагает собственной «программой» работы с материалом: c. f. — ритмическим выделением напева, c. fl. — колорированным изложением первоисточника, сквозное имитационное письмо — богатой имитационной работой. Общей является функция первоисточника — тематической основы произведения. В обозначенном временнóм поле названные техники реализуются принципиально нелинейно. Возможно, это объясняет ситуацию с их взаимодействием: колорирование (примета c. fl.) проникает в c. f., в композициях на c. f. нередко встречается имитационное письмо, а в сквозном имитационном письме подчас ощутимы и c. f., и колорирование. Отмеченная особенность анализируется на примере сочинения «Maria zart» Людвига Зенфля. Взаимодействие техник актуально не только для Возрождения. В связи с музыкой рубежа ХХ–XXI веков Ю. Н. Холопов и В. С. Ценова отмечают: «Часто соединение разных техник становится сильнейшим смысловым стержнем, на котором держится конструкция сочинения». Таким образом, для эволюции музыкального искусства данный процесс в целом естествен. Поэтому сама постановка проблемы представляется актуальной.

The musical art of the Renaissance is represented by three major techniques: cantus floridus — (c.fl.), cantus firmus (c.f.) and continious imitation writing. Each of them implies its own “program” of working with the material: c.f — rhythmic accentuation of the melody, c.fl. — colorized presentation of the original source, continious imitation writing techniques — rich imitation work. Common for the three is the function of the original source, i. e. the thematic basis of the work. In the Renaissance time these techniques develop a fundamentally nonlinear way. This may explain their interaction: coloring (the sign of c.fl.) penetrates into c.f., in compositions with c.f. one can often find imitation writing, and in continious imitation writing both c.f. and coloring are often felt. The noted feature is analyzed on the example of the composition “Maria zart” by Ludwig Senfl. Interaction of the techniques is relevant not only for the Renaissance. Referring to the music of the turn of the XX–XXI centuries, Yuriy Kholopov and Valeriya Tsenova note: “Often the combination of different techniques becomes the strongest semantic core on which the composition structure rests”. Thus, for the evolution of musical art, this process is generally natural. Therefore, problem itself seems quite relevant.
Specifics of the Interpretation of the Canon in the Works of Luigi Dallapiccola in the 1940s and 1950s
Authors: Копосова И.В.
Published: May 2021

В творчестве Луиджи Даллапикколы канон как форма и прием изложения занимает важнейшее место. Трактовка канона композитором рассматривается в статье на примере одного из ключевых этапов творчества, который связан с установлением собственного типа серийного письма, — десятилетия от начала 1940-х до начала 1950-х годов. Объектом анализа стали две сходных по своему составу пары сочинений Даллапикколы, возникшие в начале и в конце обозначенного этапа: «Каноническая сонатина» (1942–1945) и «Шесть песен Алкея» (1943), а также «Музыкальная тетрадь Анналиберы» (1952–1953) и «Песни на стихи Гёте» (1953). Их сравнение показало целый ряд отличий в подходе композитора к канону. В более ранних циклах каноническое изложение охватывает все части, а виды используемых канонов необычайно разнообразны; в более поздних на каноническое письмо опирается только часть номеров, сам канон представлен теми формами, структура которых связана с идеей полипараметровости (ракоходный, в увеличении, в обращении). Эти, а также другие особенности циклов начала 1950-х (изменение концепции вертикали в сторону диссонантности; появление канонических закономерностей в виртуальном слое фактуры, на уровне серийной диспозиции), демонстрируют овладение Даллапикколы серийным мышлением и типом письма.

Canon as a form and principle occupied an important place in Luigi Dallapiccola’s creativity. In this paper the composer's interpretation of the canon is shown on the example of a pivotal moment of his creativity, which is related to establishment of his own type of 12-tone writing and spanned a decade from the early 1940s to the early 1950s. The object of the analysis is two similar pairs of works by Dallapiccola, which appeared at the beginning and at the end of the indicated stage: “Sonatina canonica” (1942–1945) and “Sex carmina Alcaei” (1943), “Quaderno musicale di Annalibera” (1952–1953) and “Goethe-Lieder” (1953). А comparison of these opuses showed a number of differences in the composer’s approach to the canon. The canonical exposition is present in all the movements; the types of canons are unusually diverse in the earlier cycles. In later works only a part of the movements is based on the canonical writing, the canon itself being represented by the forms, whose structure is associated with the idea of total serialism (in retrograde motion, in augmentation, in inversion). These and other features of the cycles of the early 1950s (for example, the change in the vertical towards the dissonance; the appearance of canonical principles in the texture and in serial disposition), show Dallapiccola’s mastery of serial thinking and type of composition.
Correlation Between Reduced Mass and Gibbs Energy Change of Reaction
Authors: Kawashima Masatoshi
Published: May 2021

The correlation between the Gibbs free energy change of reaction and the reduced mass was clarified. In the case of bond formation reactions, the computed Gibbs energy change of reaction increased in the positive direction as the reduced mass increased. In the case of dissociation equilibrium reactions, such as the dissociation of tetrahedral carbonyl addition compound, the computed Gibbs energy change of reaction also increased in the positive direction as the reducing mass increased, but the extent of the change was smaller than in the case of bond formation reactions. The results were in good agreement with those derived from the relationship between yield and reduced mass, indicating that was originated from the correlation between the Gibbs energy change and the reduced mass.

Authors: Brumboiu Iulia Emilia , Rehn Dirk R. , Dreuw Andreas , Rhee Young Min , Norman Patrick
Published: May 2021

Here we present a derivation of the analytical expressions required to determine nuclear gradients for core-excited states at the core-valence separated algebraic diagrammatic construction (CVS-ADC) theory level. Analytical gradients up to and including the extended CVS-ADC(2)-x order have been derived and implemented into a Python module, adc_gradient. The gradients were used to determine core-excited state optimized geometries and relaxed potential energy surfaces for the water, formic acid, and benzne molecules.
Kinetics of Plasmon-Driven Hydrosilylation of Silicon Surfaces: Photogenerated Charges Drive Silicon- Carbon Bond Formation
Authors: Rao Chengcheng , Olsen Brian , Luber Erik , Buriak Jillian
Published: May 2021

Optically transparent PDMS stamps coated with a layer of gold nanoparticles were employed as plasmonic stamps to drive surface chemistry on silicon surfaces. Illumination of a sandwich of plasmonic stamps, an alkene ink, and hydride-terminated silicon with green light of moderate intensity drives hydrosilylation on the surface. The key to the mechanism of the hydrosilylation is the presence of holes at the Si-H-terminated interface, which is followed by attack by a proximal alkene and formation of the silicon-carbon bond. In this work, detailed kinetic studies of the hydrosilylation on silicon with different doping levels, n++, p++, n, p, and intrinsic were carried out to provide further insight into the role of the metal-insulator-semiconductor (MIS) junction that is set up during the stamping.

This article investigates and analyzes the development of Japanese honorifics as well as to propose effective strategies for the implementation of the situational approach in this aspect, in hope to promote the progress of Japanese language education.
Bullying Victimization Among Junior High School Students in Aceh, Indonesia: Prevalence and its Differences in Gender, Grade, and Friendship Quality
Authors: Afriani Afriani , Denisa Denisa
Published: May 2021

This study aimed to describe the prevalence of bullying victimization and its differences in gender, grade level, and friendship quality among junior high school students in Aceh, Indonesia. The study also investigated the moderation effect of gender on the association between friendship quality and bullying victimization. A total of 360 students from four schools in Banda Aceh was selected using Cluster and Disproportionate Stratified random sampling. The Revised Olweus Victim Questionnaire and Friendship Qualities Scale were used to obtain data on bullying victimization and friendship quality, respectively. The results indicated that 46.9 % of the students were reported being victimized by peers “2 or 3 times a month” or more often. Verbal was the most common form of victimization reported by students. Significant differences in bullying victimization were found concerning gender and friendship quality. The study revealed that males were more likely to report being victimized than females, while students who have a good relationship with their friends reported fewer experiences of victimization than others. Further, regression analysis indicated that gender significantly moderated the relationship between friendship quality and bullying victimization. Preventive interventions regarding peer relationships and gender may be useful in reducing bullying victimization in schools.

Published: May 2021

As we delve deeper into the roots of knowledge, we discover more and more relationships between its particular spheres, and also its descriptions or interpretations. This prompts a search for shared, interdisciplinary areas. Furthermore, what is theoretical is easier to divide into particular spheres than what is practical. The paper undertakes an attempt to seek shared areas for education under constructivism and behaviourism, in issues which appear key to education and concerning knowledge, morality and human practical acts.

Published: May 2021

Modern aquaculture is rapidly developing. It includes food fish farming and decorative fish breeding. Like in any fast-growing livestock industry, there may be problems related to the health of fish. Carp is the main object in Russian fish farming, representing the basic type of unpretentious, omnivorous and fast-growing pond polyculture. Tilapia is one of the most preferred species of global aquaculture, due to its hardiness, rapid weight gain and ability to tolerate high planting density. Discus is the most popular of the ornamental fish species; it features a large number of color variations, interesting behavior and is cost-effective in breeding. The authors carried out comparative physiological assessment of bony fish of the cyprinid and cichlid families. Hematological parameters were determined – erythrocyte and leukocyte formulas (by means of differential analysis techniques); biochemical parameters of blood serum (with the analyzer), the average cytochemical coefficient of lysosomal cationic protein content in fish blood neutrophils. The research results showed specific features in the intensity of erythro- and leukopoiesis, the proportion 32 of granular cells of the myeloid series. It was revealed that the peculiarity of discus is the presence of blast forms of white blood cells in the blood: myeloblasts, promyelocytes, and myelocytes. In the blood of tilapia, in contrast to discus and carp, there is a high content of granulocytes: neutrophils, eosinophils and basophils of monocytes and lymphocytes in the leukogram. Differences between species were noted based on the results of the lysosomal cation test. The difference in a number of biochemical parameters can also be seen: in tilapia as compared with other species – in the content of albumins, alkaline phosphatase and ALT, in discus – in the activity of lactate and KK enzymes.

Published: May 2021

Field experiments with soft wheat and malting barley, conducted on sod-podzolic medium loamy soil showed that under the influence of increasing rates of nitrogen nutrition in the leaf juice in the first stem node phase, the concentration of amino acids decreases. This fact is confirmed by high correlation coefficients. There is also a close correlation between the concentration of amino acids in the leaf juice, plant productivity and grain quality indicators. Wheat showed a close negative correlation of the concentration of amino acids in the leaf juice with the weight of 1000 grains, the total content of proteins and gluten in the grain, as well as gliadin and glutenin proteins, and a close positive correlation with the content of water-soluble, non-extractable proteins in the grain and the activity of proteases. The concentration of amino acids in the malting barley leaf juice was negatively correlated with the total content of proteins in the grain, the amount of gordeins, the total activity of amylases, and positively correlated with the test value indicators, grain extractivity, and the content of water-soluble proteins in the grain. The research results indicate that the concentration of amino acids in the leaf juice in the first stem node phase provides for a fairly accurate diagnoctics of nitrogen nutrition and prediction of the quality of soft wheat and malting barley grains.

In a simulated adult trauma patient, can pelvic binders be applied accurately by paramedics and HEMS paramedics? A pilot observational study
Authors: McCreesh Samuel
Published: May 2021

Background: Pre-hospital treatment of suspected haemorrhagic pelvic fractures includes application of a purpose-made pelvic binder. Recent hospital studies identified poor accuracy of pelvic binder application, but there is little pre-hospital research to date.Methods:
A pilot observational study was conducted in an NHS ambulance service to examine the accuracy of landmark identification and pelvic binder application. Paramedics and Helicopter Emergency Medical Service (HEMS) paramedics were recruited via an internal advert. Participants were asked to name
and identify the landmarks (greater trochanters) on a simulated patient and apply the Prometheus pelvic splint. Participants read two clinical scenarios and indicated if they would apply a pelvic binder. Descriptive and inferential statistics were used in the analysis of results to compare
performance between the two groups.Results: Twenty-six paramedics were recruited. A total of 92.3% (n = 12) paramedics and 100% (n = 13) HEMS paramedics verbalised the correct landmarks. A total of 23.1% (n = 3) paramedics and 61.5% (n = 8) HEMS paramedics identified the correct
landmarks on both sides of the pelvis. A total of 15.4% (n = 2) paramedics and 61.5% (n = 8) HEMS paramedics applied the pelvic binder centrally over both greater trochanters. Clinical decision-making to apply a pelvic binder was largely in accordance with a local standard operating procedure.Conclusion:
This study supports existing research highlighting cases of inaccurate pelvic binder placement. HEMS paramedics were more accurate than paramedics, but only 39% of all binders placed in the study were applied correctly. Frequent exposure to major trauma and familiarity with pelvic binders
may have resulted in greater accuracy among HEMS paramedics. Further education and training around clinical assessment of the pelvis may improve the accuracy of pelvic binder application by all paramedics. This would subsequently improve the quality of patient care and ensure adequate haemorrhage
control is maintained.
Paramedic independent prescribing: a qualitative study of early adopters in the UK
Authors: Stenner Karen , van Even Suzanne , Collen Andy
Published: May 2021

Background: Paramedics working in advanced practice roles in the UK can now train to prescribe medicine. This is anticipated to benefit patient access to medicines and quality of care where there is a national shortage of doctors, particularly in primary care.Aim:
To explore the experience of paramedics who are early adopters of independent prescribing in a range of healthcare settings in the UK.Design and setting: A qualitative study involving interviews between May and August 2019, with paramedics in the UK who had completed a prescribing
programme.Methods: Individual interviews with a purposive sample of paramedics recruited via social media and regional paramedic networks. Interviews covered experiences, benefits and challenges of the prescribing role. A framework analysis approach was used to identify key themes.Results:
Participants were 18 advanced paramedics working in primary care, emergency departments, urgent care centres and rapid response units. All participants reported being adequately prepared to prescribe. Key benefits of prescribing included improving service capacity, efficiency and safety, and
facilitating advanced clinical roles. Challenges included technological problems, inability to prescribe controlled drugs and managing expectations about the prescribing role. Concerns were raised about support and role expectations, particularly in general practice.Conclusion:
Paramedic prescribing is most successful in settings with a high volume of same-day presentations and urgent and emergency care. It facilitated advanced roles within multidisciplinary teams. Concerns indicate that greater consideration for support infrastructure and workforce planning is required
within primary care to ensure paramedics meet the entry criteria for a prescribing role.

Authors: Shaaban Eman
Published: May 2021

This study investigated the perceptions of science and math educators and their students at the Lebanese University related to online teaching and learning during the Covid-19 lockdown. For this purpose, two questionnaires were elaborated and validated based on two theoretical frameworks: The Community of inquiry for online learning environments and the Online collaborative learning theory. 35 educators (14 math and 21 science) and 245 students (109 math and 136 science) participated. Results showed that both science and math educators, with no significant difference between them, adjusted their courses for online teaching utilizing new resources shared with students. Online teaching allowed them to create an interactive community that encouraged students to explore concepts, construct explanations, apply and reflect on their learning. Both science and math students agreed that online learning enabled them to be more independent to explore new ideas and reflect on them with the instructor playing the role of a tutor rather than a knowledge transformer. The findings imply that online environment can allow active learning, and can provide the opportunity for students to acquire skills like, problem solving, critical thinking and collaboration. Further research is recommended related to critical thinking in online environment.

Investigation of Some Pesticides’s Effects on Lipase Under In vitro Conditions
Authors: PALÜZAR Hatice
Published: May 2021

It is known that the enzyme activities of non-target organisms are influenced in vivo or in vitro by pesticides that play a major role to obtain higher yields in the field of agriculture. It is foreseen that the pesticides used for various purposes may negatively affect lipase, an enzyme of the digestive system, of the non target organisms. Therefore, in this study, in vitro effect of diazinon (organophosphate class) and carbaryl (carbamate class) pesticides, which are known to be widely used in agriculture, was investigated and an effective dosage range of these pesticides on lipase enzyme was determined. It was observed that the lipase enzyme treated with diazinon and carbaryl in the concentration range of 100-2500 ppm was inhibited. Lipase enzyme activity at maximum diazinon concentration was calculated as 2.05%. Carbaryl completely inhibited lipase at maximum concentration The Kinetics conformed to the Michaelis-Menten model and a Lineweaver-Burk graph of the lipase was drawn. Carbaryl showed the strongest inhibitory effect against lipase (Ki: 460.96±28.25 mM; IC50: 2.5±1.3 µM) in comparison to diazinon. In the case of diazinon, Ki and IC50 value were found as 481.32±45.18mM and 3.6±0.9 µM for the lipase, respectively. The results showed that C. rugosa lipase are inhibited by diazinon and carbryl in vitro. It was shown that the catalytic activity of C. rugosa lipase is inhibited competitively by carbaryl but noncompetitively by diazinon.Keywords: Lipase, Diazinon, Carbaryl, Pesticide, Inhibition kinetics

Bu çalışmada Praseodimyum(Pr3+) katkılı ZnO [Zn1-xPrxO(x=0.01,0.02,0.03,0.04,0.05)] nanoparçacıklar kolay, hızlı ve verimli bir yöntem olan hidrotermal yöntem ile sentezlenmiştir. Sentezlenen nanoparçacıkların, kristal yapıları X-ışını kırınımıyla (XRD), yüzey morfolojileri taramalı elektron mikroskobu (SEM) ve enerji dağıtıcı X-ışını dağılımlarıyla (EDX), optik özellikleri ise dağılma yansıma (DRS UV-VIS) spektroskopisi kullanılarak karakterize edilmiştir. XRD karakterizasyonunda tüm Pr3+katkılı ZnO örneklerinin hekzagonal (wurzite) yapıda oluştuğu, praseodimyum veya praseodimyumoksit’e ait herhangi bir kırınım pikinin oluşmadığı gözlemlenmiştir. SEM görüntülerinden ZnO'in kristal yapısında Pr konsantrasyonu arttıkça daha yoğun ve daha kompakt halde olduğu görülmüştür. EDX sonuçlarından ise, sentezlenen örneklerin bileşiminde Zn, O ve Pr piklerinin varlığı tespit edilmiştir. Tüm numunelerin optik ölçümlerinden enerji bant aralıkları hesaplanmış ve hesaplanan enerji bant aralığı değerlerinin, praseodimyum konsantrasyonu ile arttığı görülmüştür.

Günümüzde yaygın olarak kullanılan yenilenemeyen enerji kaynaklarının (kömür, doğalgaz, petrol vb.) çevre üzerinde zararlı etkileri bulunmaktadır. Ayrıca bu tür kaynaklar kullanıldıkça tükenme sorunuyla karşılaşmaktadırlar. Dünyanın enerji ihtiyacını, doğaya zarar vermeden ve sürdürülebilir bir formda üretebilmek için yenilenemeyen enerji kaynakları yerine yenilenebilir enerji kaynaklarının kullanımı yaygınlaştırılmalıdır. Potansiyeli en yüksek olan yenilenebilir enerji kaynağı güneştir. Bu bağlamda güneşten enerji elde edebilmek için de güneş pilleri kullanılmaktadır. Literatürde güneş enerjisinden enerji elde edebilmek için çoğunlukla silisyum bazlı güneş pillerinin kullanıldığı belirtilmektedir. Ama bu silisyum bazlı güneş pillerinin üretimi oldukça zor ve maliyetlidir. Bu güneş pillerinin olumsuzluklarını ortadan kaldırmak için literatürde güneş pilleri üzerine çalışmaların yapıldığı görülmektedir. Bu bağlamda organik güneş pillerinden biri olan perovskit güneş pilleri üzerinde birçok araştırma yapılmıştır. Perovskit güneş pillerinin verimi, ilk üretimlerinden çok kısa bir süre sonra diğer güneş pilleri ile rekabet edebilecek seviyeye çıkmıştır. Ayrıca bu güneş pillerinin maliyeti de oldukça düşüktür. Ancak perovskit güneş pilleri üretildikten sonra kararsızlık problemleri ile karşılaşmaktadırlar. Bu makalede, güneş enerjisi ve güneş pilleri ile ilgili literatürdeki makalelerin derlemesi ve değerlendirilmesi yapılmıştır.

The coronavirus, which appeared in Wuhan city of China and named COVID-19 , spread rapidly and caused the death of many people. Early diagnosis is very important to prevent or slow the spread. The first preferred method by clinicians is real-time reverse transcription-polymerase chain reaction (RT-PCR). However, expected accuracy values cannot be obtained in the diagnosis of patients in the incubation period. Therefore, common lung devastation in COVID-19 patients were considered and radiological lung images were used to diagnose. In this study, automatic COVID-19 diagnosis was made from posteroanterior (PA) chest X-Ray images by deep learning method. In the study, using two different deep learning methods, classification was made with different dataset combinations consisting of healthy, COVID, bacterial pneumonia and viral pneumonia X-ray images. The results show that the proposed deep learning-based system can be used in the clinical setting as a supplement to RT-PCR test for early diagnosis

Published: May 2021

Bu çalışma, çelik gömmeli kompozit kolonların, beton dayanımı ile boyuna donatı oranının değişimine göre eksenel basınç kuvveti etkisindeki davranışını açıklamaktadır. Bu sebeple, dört farklı boyuna donatı (ϕ16-20-24-30), beton sınıfı (C40-50-60-70) ve yapısal çelik yüzdesi (%1-2-4-8) için on altı farklı grup olmak üzere toplamda altmış dört model oluşturulmuştur. Her bir model için önce Çelik Yapıların Tasarım, Hesap ve Yapımına Dair Esasları (ÇYTHYE-2016) ve American Institute of Steel Construction (AISC 360-16) standartlarında tanımlanan eksenel kuvvet-moment etkileşim grafikleri elde edilmiştir. Bu grafiklerden her farklı grup için taşıyabileceği maksimum eksenel basınç kuvveti hesaplanmıştır. Oluşturulan modellerdeki beton, yapısal çelik ve boyuna donatıya ait eksenel basınç kuvvetleri, yerdeğiştirmeler, şekil değiştirmeler, akma noktaları ANSYS sonlu elemanlar programı kullanılarak elde edilmiştir. Beton basınç değeri arttıkça eksenel taşıma kapasitesinin arttığını fakat eğilme momenti değerinin birbirlerine çok yakın gerçekleştiği ve sadece çelik oranı değiştirildiğinde ise eksenel basınç dayanımının sabit kaldığı, eğilme moment değerlerinin arttığı görülmüştür. Yönetmeliklerde verilen ampirik ifadeler kullanılarak hesaplanan en büyük eksenel basınç kuvveti değeri ile ANSYS’den elde edilen değerler birbirleri ile uyumlu çıkmışlardır. Analizlerin göstermiş olduğu en önemli sonuç çelik gömmeli kesitlerde kullanılan çelik profilin taşıma kapasitesinin tamamının kullanılabildiğidir.
