Beginnings of wetland science in Britain: Agnes Arber and William H. Pearsall
Authors: van der Valk Arnold
Published: September 2023

Agnes Arber (1879-1960) and William H. Pearsall (1891-1964) were two of England’s most influential antecedent wetland scientists. Arber was a plant anatomist specializing in monocotyledons, whose only major contribution to wetland science was her 1920 book, Water Plants. It was the first compendium of information on wetland plants in English and summarized the literature on their life histories, anatomies, ecologies, and evolution. It remained the standard reference on wetland plants for decades after its publication. William Pearsall began studying the ecology of wetland plants in the lakes of the English Lake District as a young man. This early research (1913-1920), which he did with the help of his school-teacher father, identified the environmental factors (substrate type, siltation rates, maximum light penetration, wave action, etc.) that determined the distribution of wetland plants and changes in the lake basins over time. In the late 1930s, Pearsall pioneered measuring electrical potential (redox) in soils to characterize their chemical status (oxidizing or reducing). He documented that soil electrical potentials became more negative as soils flooded and increased in organic matter. Pearsall also played a major role in the establishment (1929) and initial research program (Honorary Director, 1931-1937) of the Freshwater Biological Association, Britain’s first research organization dedicated to studying aquatic systems.

Great Meadows National Wildlife Refuge in eastern Massachusetts has been recognized as a Wetland of Distinction by the Society of Wetland Scientists. It provides essential habitat for migratory birds as well as for resident wildlife including state endangered birds: least bittern (Ixobrychus exilis), pied-billed grebe (Podilymbus podiceps), upland sandpiper (Bartramia longicauda), American bittern (Botaurus lentiginosus), and two state threatened species grasshopper sparrow (Ammodramus savannarum) and king rail (Rallus elegans). Great Meadows also harbors the largest genetically distinct populations of threatened Blanding’s turtle (Emydoidea blandingii) in the Northeast. The refuge also provides outdoor recreation opportunities (hunting, fishing, and nature observation) and a place for environmental education.
MODIFICATION OF THE SLUDGE FROM SODA PRODUCTION
Authors: Kuznecov D. V. , Astashina M. V. , Sinicin D. A.
Published: September 2023

The problem of disposal of sludge from soda production is relevant in the Republic of Bashkortostan. Sludge  from soda production are dumped into sludge collectors, which have a negative impact on the environment. There is a threat of contamination of groundwater with a highly mineralized still waste liquid. The increase of sludge in sludge reservoirs creates additional pressure and increases infiltration into groundwater. These processes are harmful for the ecological situation in the region.

In this paper modification of soda sludge produced by organosilicon liquid, sodium liquid glass and stearic acid. Dependencies of change of oil capacity index on gasoline with respect to time were investigated. Analysis of results was carried out and optimal formulation of sorbent based on soda sludge for utilization of liquid phase of oil sludge was revealed.

As a result of the studies of liquid glass as a hydrophobic compound it was found that small fractions of modified soda sludge repel water, creating a greasy sediment at the bottom, and granules, in turn, allow water to be absorbed and filtered without breaking their shape. To use modified soda sludge with liquid glass as a filter media in cassettes, granulation by extrusion is recommended. The resulting sorption materials based on the modification of soda sludge with sodium liquid glass can be recommended for use in facilities for the treatment of surface and waste water from heavy metal ions.
DEVELOPMENT OF A DIGITAL MODEL OF A PIPELINE IN PERMAFROST SOILS
Authors: Sultanmagomedov T. S. , Khalikov T. M.
Published: September 2023

The work is devoted to the study of the stress-strain state of a pipeline laid in permafrost soils. The essence of the study is the development and verification of a tool for assessing the stress-strain state of a pipeline when changing the properties of the soil around the pipeline.

The purpose of this study is to develop a computer model that takes into account the dependence  of  the  mechanical properties of permafrost soils on temperature when calculating the stress-strain state of the pipeline during the destruction of thermal insulation.

Research objectives:

1. development of a coupled thermal and mechanical model of a pipeline in permafrost soil in application software;

2. adding to the calculation model the dependence of soil properties on temperature;

3. adding to the calculation model a change in the volume of soil due to freezing of liquid in the soil. Adding properties of heaving soil.

The introduction deals with digital and analytical coupled thermal, mechanical and hydraulic models. The choice of a software package for modeling processes is substantiated, and the relevance of such modeling is also shown.

The simulation of the pipeline defrosting process is carried out using the ANSYS software, which is based on the finite element method. The article shows the developed model of the pipeline, as well as the details of setting up such a model for thermal mechanical calculation. Features such as specifying loads and boundary conditions by steps, as well as setting the relationship of these steps are given.

Based on the results of the thermal calculation, it was revealed that the depth of thawing in case of violation of thermal insulation for given boundary conditions varies from three to five meters from the daytime surface of the soil. With such a spread of the boundaries of the thawing halo, the pipeline deflection varies from 0 to 300 mm, while the equivalent stresses increase from 10 to 140 MPa.

To improve the model, a method is proposed for setting the properties of soil heaving using the soil linear expansion coefficient. An experimental bench is proposed for determining the values of this coefficient depending on soil moisture and temperature difference.

Padres en la adolescencia en la pobreza urbana de Montevideo: una mirada desde el concepto de ética sexual
Authors: De Martino Bermúdez Mónica
Published: September 2023

Resumen. La investigación, de carácter exploratorio, tuvo como objetivo abordar e identificar algunos de los aspectos que asumen las experiencias de la paternidad en la adolescencia pobre. La estrategia metodológica fue de índole cualitativa y amparada en la aplicación de testimonios de vida a padres y madres adolescentes y entrevistas a agentes profesionales insertos en diversos programas sociales que abordan el tema. La investigación rescata a Foucault (1986) que otorga al ejercicio de la sexualidad la capacidad de constitución de un sujeto que a través de la sexualidad se constituye como tal y logra darle un sentido estético (estilo) a su vida. Algunos de los hallazgos indican que la ética sexual que rige a estos padres se asocia, en general, a masculinidades hegemónicas en diversos grados de pureza conceptual. La centralidad del trabajo, como elemento ordenador profundo de la vida, se asocia a ciertas dosis de flexibilidad de la masculinidad hegemónica.

Merits and Challenges of Comparing the EU and Canada
Authors: Hoppe Alexander , Thorlakson Lori , Gómez Johannes Müller
Published: September 2023

In the last decades, EU studies have increasingly broadened in terms of their theoretical and methodological approaches. By now, comparative concepts and theories are an integral part of studying the EU, which aids the study of its polity, politics, and policies. Despite the indisputable peculiarity of the EU as a political system, many scholars have stressed the value of using comparative approaches to study it. This thematic issue aims to investigate a specific case—the political system of Canada—as to its merit for comparison with the EU. While both systems have been described as sui generis in the past, forming a class of political system by themselves, recently the similarities between both have been stressed. This thematic issue gathers articles that compare different aspects of these two systems—focusing on polity, politics, and policy—to reap the benefits of the comparative approach and gain new insights into the functioning of both systems. The contributions to the thematic issue show the benefits that both Canadian political science and EU studies can gain from engaging in comparative exercises.
BUSINESS CYCLE TRENDS WITHIN THE EUROPEAN CORE AND PERIPHERY: IMPLICATIONS FOR UKRAINE
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Zholos Taras , Mazurenko Valerii ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: September 2023

Economic theory suggests that economic integration can promote business cycle co-movement, which in turn facilitates the institution of common counter-cyclical policies. However, evidence from empirical studies on co-movement within the EU and Europe as a whole is mixed, particularly concerning a so-called group of peripheral countries. This article argues that the existence of large international shocks and their heterogeneous impact on national economies changes the interpretation of co-movement. A decomposition of business cycles into common and country-specific components via a flexible Bayesian dynamic factor model with time-varying parameters and stochastic volatility reveals that the patterns of co-movement among the EU core and periphery are similar after common shocks – such as the Great Recession and the COVID-19 pandemic – and the upward bias introduced by the use of the Pearson correlation coefficient is accounted for. However, it is found that there is another important distinction between the EU core and periphery; that is, during the period of the Great Re-moderation that followed the Great Recession, the business cycles of the core EU countries converged to a lower level of volatility than those of the periphery. Moreover, it is shown that various standard measures of business cycle co-movement can conflate co-movement and volatility convergence, which alters their interpretation. Importantly, this article relates the experience of the EU core and periphery to that of Ukraine. In particular, it is found that the business cycle of Ukraine is similar to those of the EU periphery in terms of the level of its volatility and co-movement vis-à-vis the core EU countries, which has important implications for further development of Ukraine's European integration policy.

The effect of the subphase temperature on the formation of nickel arachinate clusters under a monolayer of arachidic acid was studied. The subphase temperature varied in the range from 10° to 30°C with a step of 4°C. The influence of temperature on the compressibility of the monolayer and the area occupied by one molecule in the Langmuir monolayer of nickel araquinate is demonstrated. The effect of temperature on the morphology of Langmuir-Blodgett films formed on their basis was also studied. It was found that, as the temperature changes, the number of nickel clusters increases and their sizes decrease. This is due to a change in the rate of growth and dissolution of clusters with a change in temperature. The distribution of clusters in the resulting film was random, however, they can be structured using external magnetic fields. Using the magnetic properties of NiArch clusters will make it possible to purposefully change the film structure by an external magnetic field. The results obtained are of great importance for practical applications in the creation of multilayer composite coatings with controlled magnetic properties. These films can be further used as touch coatings for acoustic and electronic sensors.

The work examined the sensor properties of a biofilm based on phospholipid molecules 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine with immobilized molecules of the enzyme alcohol oxidase to vapors of ethyl and isopropyl alcohols. The immobilization of alcohol oxidase enzyme molecules was carried out using a Langmuir monolayer process of phospholipid molecules. The sensor coating was obtained using the Langmuir-Schaeffer technology, in which the substrate is oriented parallel to the monolayer. The analysis of microimages of the film surface obtained by atomic force microscopy, allows to present of enzyme molecules in it was established. The study of the sensory properties of the formed coatings was carried out using acoustoelectronic technology. The presence of the enzyme in the sensor coating led to an increase in the amplitude and phase responses of the acoustic delay line when interacting with vapors of the detected substance. The maximum amplitude and phase responses were recorded when the film interacted with ethanol vapor and were 1.5 dB and 19°, respectively. The work showed that the formed sensor coating has selective sensitivity to ethanol vapor. This allows us to conclude that it is possible to use this sensor coating to create an acoustoelectronic ethanol biosensor. Increasing the sensitivity of such biosensors can be achieved by varying technological parameters such as the number of layers in the film, as well as the amount of immobilized enzyme in each layer.

Published: September 2023

The article analyzes the issues of risk distribution of failure to achieve results in the provision of medical services and concludes that the distribution of risks falls on the customer of such a service. The beneficial effect of the medical service is absorbed by the patient in its process. Despite the wording of the legislation on the protection of citizens’ health, quality assessment issues are solved not through the prism of determining the degree of achievement of any result, but through the ratio of performed actions (medical manipulations) in comparison with the prescriptions of the standard of medical care. The authors believe that the medical service itself never has a materialized result, the intangible result is also not guaranteed by the service provider, but only the proper fulfillment of the terms of the contract by him. It is revealed that the medical service does not have a materialized result, and the objects that are used in the process of medical manipulations arise from contractual relations and are used as things in the process of providing a medical service. It is concluded that such things become part of human tissues and organs as a result of their implantation and lose the properties of things, becoming an integral component of his body. The medical organization guarantees the proper performance of the service, which ensures a balance of interests of the participants in legal relations for the provision of medical services, in which each party is obliged to fulfill the terms of the contract properly.

Authors: Anisimov Viktor R. , Klimov Alexandr V.
Published: September 2023

BACKGROUND: Fuel cells are one of the promising directions in the development of electrified transport as it is capable of providing with mileage comparable to conventional vehicles powered by internal combustion engines, with no harmful emissions into the environment during the vehicle motion. The long-lasting process of development of fuel cells was associated with the inability to realize the potential of fuel cells and the availability of more accessible and reliable energy sources at that time. The present programs and measures to support electric vehicles and fuel cells set targets for reducing emissions of harmful gases and increasing the share of electric vehicles on the roads.
AIMS: The study of the history of the development of fuel cells and their relevance to the use in vehicles.
METHODS: The calculations to determine the specific parameters were performed with solving the differential equation of the force balance of vehicle motion using the numerical Euler method.
RESULTS: The results of the scientific research are the determination of specific parameters of power units and the analysis of the history of the development of fuel cells. By comparing the specific parameters, it was revealed that the most effective are combined power units on fuel cells. When using these power units, a 2.5-fold decrease in mass was recorded compared to other types of power units.
CONCLUSIONS: The use of fuel cells helps to reduce the weight of the power units and to improve the environmental safety of the vehicle. Fuel cells have undergone several long stages of development and reached their peak of development after the beginning of active space exploration. Currently, the development of hydrogen technologies is actively continuing, programs for the development of electrified transport have been issued in many countries, including the Russian Federation.
The authors note the relevance of scientific research in this area and assume that vehicles powered by electrochemical generators will receive their further development in the coming years.

Published: September 2023

BACKGROUND: Increasing energy efficiency of an electric vehicle is one of the most relevant issues at the current state of transport development. It is known that chemical current sources used in traction electric drive of vehicles have low specific power, low efficiency and high cost that makes the electric transport development difficult.
AIMS: Making the choice of strategy of manufacturing of electric vehicle with batteries.
METHODS: The mathematical models of various vehicle driving cycles, such as: the UNECE Regulation 83 urban cycle, NEDC, WLTC, JC08, EPA HWEET were used in the study that made possible to confirm adequacy of the developed structural model of the electric drive.
RESULTS: The structural layout of the traction electric drive of an electric vehicle with combined energy source has been developed; the algorithm of its operation in the urban driving cycle has been defined. Electric transport efficiency was assessed during the study. The analysis showed that vehicles with solely chemical on-board energy sources do not have any prospects due to unsatisfactory technical properties and consumer attributes. Review of capacitors was performed in order to define the possibility of using them as energy source for next-generation vehicles. The study revealed sufficient advantages of capacitors in many respects. Analysis of vehicle motion in urban cycle was performed in order to develop the optimal design. The electric drive layout with a lithium-ion traction battery as the main energy source and a capacitor as the additional energy source was chosen.
CONCLUSIONS: This solution makes it possible to develop the electric drive with optimal mass and dimensional parameters, to increase service life of energy storage and mileage without recharging of a vehicle. In addition, the combination of two electric energy accumulators and the developed algorithm of their operation makes it possible to achieve high efficiency of energy transferring.

BACKGROUND: Innovative technologies and design solutions aimed at using hydrogen in internal combustion engines and hydrogen power plants are reviewed in the paper. The advantages of hydrogen fuel are shown and the main problems that Western automakers face and which determine the ways to solve problems in road transport are identified. In this regard, the method of using hydrogen energy in internal combustion engines and hydrogen power plants becomes a decisive factor.
AIMS: Search for a reasonable and effective method of using hydrogen in transport.
METHODS: The technologies of hydrogen production with the electrolysis method and on-board generation of hydrogen using hydrogen-containing components are considered. It is proposed to use ammonia as a hydrogen carrier reagent for operation in dual-fuel diesel internal combustion engines.
RESULTS: It is noted that ammonia, with a high level of hydrogen content in the molecule, is relatively safe, has a low cost and a significant volume of production. It is easier to store and transport compared to hydrogen. For internal combustion engines operating on hydrocarbon fuel, the use of ammonia and hydrogen, its derivative product, is attractive due to the need to remove highly toxic nitrogen oxides containing in the exhaust gases of diesel internal combustion engines.
One of the main problems of creating an environmentally friendly diesel engine associated with reducing the NOx content to an environmentally safe level is considered. A positive factor of using ammonia is the on-board production of hydrogen in the thermal reactor, as well as the possibility of organizing an effective process of neutralizing nitrogen oxides in a diesel engine.
CONCLUSIONS: The use of ammonia to generate hydrogen allows the diesel engine to implement the process of selective reduction of nitrogen oxides when ammonia is injected into the combustion chamber at the exhaust stroke. This method will significantly increase the efficiency of NOx neutralization in a diesel internal combustion engine due to the possibility of temperature regulation of the NOx neutralization reaction directly in the cylinder and in the exhaust system of the internal combustion engine.

Dear Editor;

We read with interest the article titled “Use of methacoline challenge test to detect bronchial hyperresponsiveness in children with persistent rhinitis” published in Cukurova Medical Journal by Guc et al. [1].

This study showed that BHR positivity is high in children with allergic rhinitis. Allergic rhinitis can cause false positive BHR. In addition, smoking and COPD can cause false positives [2, 3]. COPD can occur in childhood [4]. We think that it would be appropriate to mention this in the discussion part of this study.

Purpose: Cardiac risk factors are among the most important determinants of postoperative outcomes in elderly surgical patients. This study aimed to determine the effect of perioperative cardiac risk factors on postoperative adverse outcomes in elderly patients undergoing total hip replacement surgery.

Materials and Methods: Patients aged 65 and older who underwent total hip replacement surgery at Cukurova University Hospital between 2014 and 2019 were analyzed retrospectively. The primary outcome measures were postoperative adverse outcomes and mortality rate.

Results: Two hundred twenty-three patients with total hip replacement surgery within five years of experience in our hospital were screened. 34.5% had postoperative cardiac, pulmonary, cerebral, and infectious morbidity and systemic inflammatory response syndrome, and the in-hospital mortality rate was 2.2%. On multivariate analysis, perioperative risk factors associated with postoperative adverse outcomes included American Society of Anesthesiologists (ASA) II physical status (aOR 5.63, 95% CI 1.75-18.11), preoperative poor functional capacity (aOR 9.50, 95% CI 3.14-28.79), traumatic fracture (aOR 2.75, 95% CI 1.22-6.24), preoperative anemia (aOR 2.15, 95% CI 1.05-4.37), and prolonged surgery (aOR 1.02, 95% CI 1.01-1.02).

Conclusion: A significant relationship was determined between preoperative poor functional capacity, pre-existing anemia, traumatic hip fracture, ASA II physical status, prolonged case duration and the risk of postoperative complications in elderly patients undergoing total hip replacement surgery.

Purpose: This study aimed to investigate the characteristics of abdominal crush injuries using multidetector computed tomography (MDCT) in survivors of earthquakes centered in Kahramanmaraş.

Materials and Methods: Retrospective evaluation was conducted on 255 patients who sustained injuries due to an earthquake centered in Kahramanmaraş and were treated at our hospital. Patients clinically suspected of having abdominal crush trauma underwent MDCT examinations. The presence of abdominal wall injuries, solid organ injuries, free fluid in the abdomen, pneumoperitoneum, and subcutaneous emphysema findings were examined.

Results: The median time between injury and MDCT examination was 3 days, ranging from 4 hours to 8 days. Among pediatric and adult age groups, males constituted 42.6% (52/122) and 47.4% (63/133), while females were 57.4% (70/122) and 52.6% (70/133), respectively. The mortality rates for pediatric and adult age groups were 0.4% (1/122) and 4.3% (11/133), respectively. Among patients with fatal outcomes, rates of acute kidney injury, subcutaneous emphysema, spleen injuries, and renal/perirenal injuries were 8.3% (1/12), liver and abdominal wall injuries were 16.7% (2/12), and free fluid in the abdomen was observed at a rate of 33.3% (4/12).

Conclusion: Abdominal wall injuries were the most frequently observed manifestations of crush injuries, with renal/perirenal injuries being the most common among solid organs, and liver injuries being commonly seen among intraperitoneal organs. These findings underscore important characteristics of abdominal crush trauma related to earthquakes.
X Kromozomu İnaktivasyonu ve İnaktivasyondan Kaçış
Authors: GÜNAŞTI Başak

X kromozomunun inaktivasyonu dişi memelilerde iki tane olan X kromozomlarından bir tanesinin inaktive edilmesidir. İnaktivasyona uğrayacak X kromozomu, heterokromatin şeklinde paketlenmektedir. Böylece bu X kromozomunun üzerindeki genlerin eksprese edilmeleri önlenmektedir. İnaktivasyon işlemi, bir adet X kromozomu bulunan erkekler ile iki adet X kromozomu bulunan dişiler arasındaki dengeyi sağlamaktadır. X kromozomu inaktivasyonu, inaktive edilecek tüm X kromozomunda gerçekleştiği düşünülse de, X kromozomunun üzerindeki genlerin tamamı inaktivasyona maruz kalmayıp bir kısmı inaktivasyondan kaçmaktadır. İnsanlarda X kromozomundan kodlanan genlerin yaklaşık %12 ile 20'si kadarı inaktivasyon işleminden kaçarak eksprese olabilmektedir. Derlemede, X inaktivasyonunun mekanizmaları ele alınarak, aktivasyon sürecini ve aktivasyondan kaçan genleri inceleyeceğiz.

Published: September 2023

Sinir sistemindeki nöronal ağlar, canlılar için hayati önem taşıyan; hareket, nefes alma, duruş ve denge gibi çeşitli davranışların yönetiminde merkezi rol oynar. Gelişim sırasında farklı nöron tipleri arasındaki sinaptik bağlantılar, bu hayati işlevleri kolaylaştıran sinir ağlarının temel mimarisini oluşturur. Spinal kord, bu nöronal ağları oluşturmak üzere birbirine bağlanan dengeli sayıda eksitator (Glutamaterjik) ve inhibitör (GABAerjik) nöronları içerir. Bugüne kadar yapılan çalışmalarda, spinal korddaki çeşitli nöron popülasyonlarının gelişimini tanımlamak ve yönlendirmek için merkezi sinir sistemi (MSS) gelişimi boyunca eksprese olan ve fonksiyon gören transkripsiyon faktör (TF) ağları araştırılmıştır. Dorsal spinal kordda eksitatör ve inhibitör nöronlar arasındaki dengenin, erken gelişim aşamasında temel sarmal-döngü-sarmal (bHLH) transkripsiyon aktivatörleri ve PRDM13 repressörü arasındaki etkileşim süreciyle belirlenir. bHLH TF'leri olan ASCL1 ve PTF1A, sırasıyla eksitatör ve inhibitör nöron gen ekspresyon programlarını başlatırken, PRDM13, alternatif hücre kaderlerini susturmak için gereklidir. Burada kilit nokta, bHLH ve PRDM faktörlerinin, embriyogenez boyunca progenitör hücrelerde (öncü hücre) nöron çeşitliliğini oluşturmak üzere kritik kader seçim noktalarında eksprese olmasıdır. Nöron alt tiplerinin belirlenmesinde bu faktörlerin işlevleri konusunda önemli ilerlemeler kaydedilmiş olmasına rağmen, belirli gen programlarını nasıl düzenlediği ile ilgili mekanizmalar henüz açık değildir. Bu mekanizmaların ortaya çıkarılması, gelecekte sinir sistemi gelişimindeki bozuklukların çözümüne ve gelişim anomalileri sonucu oluşan klinik problemlerin tedavisine yönelik araştırmalara ışık tutacaktır.
Kutb-i Nâyî Osman Dede’ye Göre İran Klasik Müziğinde “Heft Destgâh”
Authors: HÜSEYNİ Seyid Muhammed Taki
Published: September 2023

Mûsikî ilmi ve sanatı, tarih boyunca çeşitli etkenlerden dolayı sürekli değişimlerde olduğu gibi, İran klasik müziği de zamanla değişmiştir. İslâmiyet öncesi “râh” sisteminde uygulanan İran musikisi, İslâmiyet sonrası yerini “edvâr” ve “makam” sistemlerine vermiştir. Bu sistemler zamanla yine değişmiş ve günümüzde “destgâh” adı ile anılmaya başlamıştır. “Heft (yedi) Destgâh” sistemine geçiş sebepleri, tarihî süreci, kavramı ve neden yedi olduğu ile ilgili mûsikî risâlelerinde ve tarihî kaynaklarda her hangi bir net açıklamayla karşılanmamıştır. Çağımızdakı müzikologların ve araştırmacıların çalışmaları neticesinde de kesin bir açıklama yapılmamıştır. Destgâh ile ilgili araştırmamıza göre, en eski açıklama Kutb-i Nâyî Osman Dede’nin mûsikî konusunda yazdığı Farsça manzum Rabt-ı Tağyîrât-ı Mûsikî adlı eserinde bulunmaktadır. Osman Dede, İran’da uygulanan sistemden “Heftgâne” (yedili) tabiri ile söz ederek görüşünü aktarmıştır. Bu makalede İran mûsikîsi ve “destgâh” sistemi ile ilgili bilgiler verdikten sonra Osman Dede’nin hayatı, eserleri ve Rabt-ı Tağyîrât-ı Mûsikî‘sinde İran mûsikîsi ve “destgâh” sistemi ile ilgili yorumlarına yer verilmiş ve değerlendirilmiştir.
