Authors: Morozova Irina I. , Tikhonova Natalia V. , Timoshina Yulia A. , Voznesensky Emil F.
Published: December 2021

The article presents the results of a study on the functionalisation of synthetic textile materials with spherical activated carbon using an adhesive to create personal protective equipment based on Russian components. These materials are of particular relevance in the production of sorption and filtering personal protective equipment, which must have, along with high protective characteristics, high performance properties, vapour and air permeability. In the course of the work, the influence of the plasma of a capacitive high-frequency and low-pressure discharge on the modification of the base material was investigated. It has been proven that plasma treatment of polyester nonwoven material accelerates sorption processes, ensures uni-form coverage of fibres with a binder, which allows maintaining the material's air permeability. The results of studies of the material for the time of protective action on ammonia demonstrated the prospects for the development of Russian sorption-filtering textile material on a non-woven polyester base with a monolayer of granular activated carbon fixed on a polymer binder.

Authors: KAN Mehmet
Published: December 2021

Son zamanlarda nanoteknolojinin gelişmesi, baz akışkanların ısı transfer özelliklerini geliştirmek için kullanılması fikrinin kullanılmasında artış olmuştur. Özellikle ısı eşanjörlerinde nanoakışkanların kullanılması yaygınlaşmıştır. Bu çalışmada, spiral bir ısı eşanjöründe farklı Al2O3 su nanoakışkan karışımlarının termal davranışlarının karşılaştırılması nümerik olarak incelenmiştir. Spiral ısı eşanjöründeki ısı transferinin bilgisayar destekli analizi su ve su bazlı nanoakışkanlar üzerinde yapılmıştır. Nanoakışkanlar içerisindeki Al2O3 nanoparçacığının farklı hacim konsantrasyonları (%1, %2 ve %3) ve su özellikleri belirlenerek, spiral bir ısı eşanjöründe analizleri gerçekleştirilmiştir. Nanoakışkanların termo fiziksel özelliklerinin nanopartiküllerin hacim konsantrasyonlarına ve sıcaklığa bağlı olarak değişimi gözlemlenmiştir. Isı transferi ve ortalama ısı transfer katsayısı, nanopartiküllerin farklı hacim konsantrasyonları için sayısal olarak hesaplanmış ve elde edilen sonuçlar karşılaştırılmıştır. Çalışmadaki farklı hacim konsantrasyonları arasında en iyi sonuçlar %3 hacim konsantrasyonuna sahip nanoakışkanda elde dilmiştir. Ayrıca %3 hacim konsantrasyonuna sahip nanoakışkanda suya göre ısı transferinin %47 ve toplam ısı transfer katsayısının %24 daha iyi olduğu hesaplanmıştır.
Polimerik Bir Zincir Uzatıcının Geri Dönüştürülmüş Poli(Bütilen Tereftalat)’ın Özelliklerine Etkilerinin İncelenmesi
Authors: TUNA Başak
Published: December 2021

Poli(bütilen tereftalat) (PBT) günümüzde en fazla kullanılan poliesterlerdendir, ancak PBT atıkların geri dönüşüm kapsamında katma değerli ürünlere dönüşmesine yönelik girişimler hala sınırlıdır. PBT geri dönüşümünün en önemli zorluklarından birisi çoklu eriyik işleme döngüleri sırasındaki termal bozunma olup, polimerin molekül ağırlığı ve özelliklerinde kayıplara yol açmaktadır. Bu çalışmada geri dönüştürülmüş PBT (Gd. PBT) farklı yükleme oranındaki (%ağ. 0.5, 1, 1.5) polimerik bir zincir uzatıcı (Joncryl ADR 4368) ile çift vidalı ekstrüderde harmanlanmıştır. Örneklerin reolojik, mekanik ve termal özellikleri farklı karakterizasyon yöntemleri ile incelenmiştir. Reolojik sonuçlar zincir uzatıcının eklenmesiyle kopan zincirlerin tekrar bağlanarak Gd. PBT’nin viskoelastik özelliklerinin geliştiğini göstermiştir. Zincir uzatıcının Gd. PBT’nin özelliklerine olan önemli etkisi çekme testi sonuçlarından da doğrulanmıştır. Zincir uzatıcı içeren örneklerin elastik modül ve çekme dayanımları artış gösterirken, kopmadaki uzama değerleri zincir dallanmasına bağlı olarak düşmüştür. Zincir uzatıcının örneklerin dallanmış yapısına etkisi düşük kristalinite değerlerinden de gözlemlenmiştir. Termogravimetrik analiz zincir uzatıcının Gd. PBT’nin termal bozunma sıcaklığını arttırdığını göstermiştir. Zincir uzatıcı içeren örneklerin özelliklerindeki iyileşme artan zincir uzatıcı konsantrasyonu ile daha belirgin olmuştur.

Ideal de cuerpo femenino y cultura de la dieta:
Authors: Barrera Carranza Yamile Zureyma
Published: December 2021

En todas las épocas, el ideal de cuerpo femenino está determinado por el concepto de belleza de cada cultura, según las tradiciones o problemas de la sociedad. Por ejemplo, en la cultura egipcia, se apreciaba a la mujer que tenía un cuerpo delgado, espalda angosta, cintura pequeña, piernas largas y rostro simétrico. Desde el año 2000 hasta la actualidad, el ideal de cuerpo femenino consiste también en mantener una complexión delgada, pero resaltando el área muscular del busto, glúteos, abdomen y muslos. Es por eso que la mujer actual intenta alcanzar este ideal de cuerpo femenino de distintas maneras, que pueden poner en riesgo la salud física y mental. Por un lado, manipula las fotografías que comparte en las redes sociales; y por otro, sigue distintas dietas de moda que no cumplen con las características de una alimentación correcta, o peor aún, adopta conductas alimentarias de riesgo. Es importante promover un estilo de vida saludable y no considerar la salud solamente como algo reduccionista, inmediato y pasajero; porque además la identidad de una mujer abarca lo físico, mental y social. Por ello, en esta revisión se recomienda practicar una salud integral, mediante el conocimiento de evidencia científica compatible con la mujer

Humerus Lateral Kondil Kırığı Olan İki Yaşındaki Pediatrik Hastada İnfraklavikular Blok Deneyimimiz: Olgu Sunumu
Authors: ŞENGEL Abdulhakim
Published: December 2021

Rejyonel anestezi yöntemi, pediatrik hastalarda erişkin hastalara nazaran daha az başvurulan bir anestezik yöntemdir. Ultrasonun klinik uygulamada artan popülaritesi ile beraber hedef sinirin ve lokal anestezik yayılımının doğrudan görüntülenebilmesi pediatrik hastalarda da rejyonel anestezi uygulamasına olanak sağlamıştır. Ancak klinik pratiğe ve literatür taramasına bakıldığında bu uygulamaların hala istenilen düzeyde olmadığı rahatlıkla söylenebilir. Bundan dolayı bu konudaki deneyimlerin bilimsel platformlarda daha çok tartışılıp paylaşılması gerektiğini düşünüyorum. Bu anlamda bir gün önce düşme sonucu Humerus lateral kondilinde kırık meydana gelen ve son bir haftada ağır bir üst solunum yolu hastalığı geçirme öyküsü olan 30 aylık bir çocukta ultrason rehberliğinde uyguladığım İnfraklavikular Brakiyal Pleksus bloğu yöntemi hakkındaki deneyimimi sunmak istedim.

Online Adaptation of Two-Parameter Inverter Model in Sensorless Motor Drives
Authors: Chen Jiahao , Mei Jie , Yuan Xin , Zuo Yuefei , Zhu Jingwei , Lee Christopher H. T.
Published: December 2021

This paper designs parameter adaptation algorithms for online simultaneous identification of a two-parameter sigmoid inverter model for compensating inverter nonlinearity to reduce the voltage error in flux estimation for a position sensorless motor drive. The inverter model has two parameters, a2 and a3, where a2 is “plateau voltage”, and a3 is a shape parameter that mainly accounts for the stray capacitor effect. Parameter a3 is identified by the (6k ± 1)-th order harmonics in measured current. Parameter a2 is identified by the amplitude mismatch of the estimated active flux. It is found that the classic linear flux estimator, i.e., the hybrid of voltage model and current model, cannot be used for a2 identification. This paper proposes to use a saturation function based nonlinear flux estimator to build an effective indicator for a2 error. The coupled identifiability of the two parameters is revealed and analyzed, which was not seen in literature. The concept of the low current region where the two-way coupling between a2 and a3 occurs is established. In theory, it is suggested to stop the inverter identification in the low current region. However, the experimental results in which dc bus voltage variation and load change are imposed, have shown the effectiveness of the proposed online inverter identification and compensation method, even in low current region.
Deep Optimized Electrodes and Frequency Bands in the Phase Space for Identification of Seizures
Authors: Rukhsar Salim , Panda Samhita , Tiwari Anil Kumar
Published: December 2021

The electroencephalogram (EEG) has been extensively used to record brain signals for the analysis of neurological
diseases over several decades. Epilepsy is the one of the most common neurological disorder in the world. It is associated with seizures, which are a clinical manifestation of abnormal, excessive excitation and synchronisation of a population of cortical neurons, resulting in abrupt changes in consciousness, movement, behaviour, and feelings. Our goal in this letter is to propose a computationally efficient EEG based system that can detect seizures with improved detection performance. To deeply optimize the electrodes and frequency bands, we proposed a fast computational algorithm by finding the critical electrodes and optimal sub-bands of EEG signals. We used wavelet packet decomposition (WPD) to find optimal sub-bands and maximum relevance minimum redundancy (mRMR) method for electrodes selection. It is found that the portrait of the features in the phase space depicted promising discriminating ability to detect seizure efficiently. Experimental results show that the proposed method outperformed the state-of-art methods and provided 100% and 94.79% of detection accuracy on UBonn and CHB-MIT datasets, respectively, at a significantly reduced computational cost.

Published: December 2021

En este artículo, se desarrolló un algoritmo, basado en la técnica de enjambre de partículas (Siglas en inglés - PSO) para optimizar los procesos de fundición a presión y por compresión, utilizando modelos matemáticos para describir el comportamiento de ambos procesos. En la fundición por compresión el modelo matemático describe un problema con múltiples objetivos y restricciones, y en la fundición a presión el modelo describe un problema de un solo objetivo con restricciones. El desarrollo del algoritmo PSO se realizó con el software FORTRAN 90, y los resultados se compararon con los obtenidos usando un algoritmo de optimización basado en el proceso de enseñanza-aprendizaje (Siglas en inglés - TLBO), demostrando buenas capacidades en la optimización de parámetros en fundición a presión y por compresión. Se observó que con el algoritmo PSO se consigue una solución óptima en todos los procesos y los tiempos computacionales fueron mínimos.
Myocardial damage in new coronavirus infection (review)
Authors: Vakhnenko Yu. V. , Korotkikh A. V. , Bagdasaryan E. A.
Published: December 2021

Introduction.Myocardial damage characteristic of novel coronavirus infection is a confirmed risk factor for its severe course and high mortality. There are biomarkers of this condition correlating with an unfavorable prognosis for the patient. However, the information on the problem of myocardial damage in the available literature is not fully systematic. It concerns pathogenesis, differential diagnosis of its causes, routing of patients with acute coronary syndrome. All the above is very important for choosing the right tactics of examination and treatment of patients, who are often limited in time. Aim.To summarize the data available at the time of writing from domestic and foreign researchers on the problem of myocardial damage and its main causes (acute coronary syndrome, myocarditis, stress cardiomyopathy) in COVID-19. Materials and methods.This review summarizes the data from articles published over the past two years found in PubMed, Google Scholar and eLIBRARY. Results.The authors tried to form a generalized modern understanding of the causes and structure of cardiovascular pathology and risk factors of its destabilization in patients infected with SARS-CoV-2, the markers of increased risk of COVID-infected heart and vascular diseases, the tactics of examination and treatment of this category of patients, routing individuals with acute coronary syndrome and its differential diagnosis with non-coronary heart diseases. The questions of organization and availability of the medical care in the conditions of the pandemic and social aspects of the world cardiology problems in the current situation have been studied. Conclusion. Patients with cardiovascular disease have a more severe prognosis of the severity and outcome of COVID-19, which is explained by its pathogenesis. The group at highest risk of lethal events is composed of individuals with signs of myocardial damage, the causes of which are the above mentioned conditions. Their differential diagnosis is a difficult clinical task, which requires a systematic analysis of the dynamics of clinical syndromes and data of additional diagnostic methods from routine to the most modern (high-tech) and, of course, deep knowledge of the present problem. The correct determination of the cause of myocardial damage and the choice of the right patient’s route through the treatment network determines the effectiveness of treatment and, therefore, the prognosis of the patient’s life.

Introduction. The role of an alternative adenylate cyclase pathway of hormonal signal transmission under the action of synthetic glucocorticosteroids with the participation of endogenous stress-limiting activity of the adrenal cortex in conjunction with the adaptive capabilities of airway homeostasis in patients with asthma under conditions of osmotic stress has not been studied at present. Aim. To assess the dynamics of cortisol and cyclic adenosin monophosphate (cAMP) in asthma patients with different airway responses to hypoosmolar stimuli when using anti-inflammatory combination therapy with inhaled corticosteroids/long-acting β2 -agonists (ICS/LABA). Materials and methods. 96 patients diagnosed with asthma received combined anti-inflammatory therapy with ICS/LABA for 24 weeks. Group 1 included patients (n=18) with airway hyperresponsiveness to hypoosmolar stimulus, group 2 (n=78) – with no reaction of the bronchi to a 3-minute ultrasonic inhalation of distilled water. At baseline and at the end of treatment, the lung function was studied; to assess the regulatory function of glucocorticoids using non-genomic signaling pathways, the levels of cortisol in blood serum and cAMP in blood leukocytes were determined. Results. Patients of group 1 in comparison with the second one initially had a lower FEV1 ‒ 88.2±5.3 and 98.5±1.7%, respectively (p<0.05), after treatment in both groups there was a slight tendency to an increase in FEV1 (98.5±5.7 and 101.4±2.5%, respectively, p>0.05). The concentration of cortisol and cAMP at baseline and after 24 weeks of therapy in patients of group 1 was 588.7±32.0 and 495.0±48.7 nmol/L, 61.7±5.1 and 76.5±5, 2 pmol/106 cells (p<0.01); in group 2 − 610.5±20.1 and 522.2±15.60 nmol/L (p<0.001), 76.2±2.2 and 90.6±2.5 pmol/106 cells (p<0.001). Conclusion. In asthma patients with airway osmotic hyperresponsiveness, persistent adaptation to osmotic stress is traced, which is combined with a more significant impairment of the lung function and indicates insufficient therapeutic control over glucocorticoid regulation of osmotic stress by the selected volume of ICS/LABA therapy.

Aim. To study the functional state of the expiratory muscles in patients with type 2 diabetes mellitus on the basis of changes in their electrical activity when using a functional test with a static expiratory effort. Materials and methods. 47 patients with type 2 diabetes mellitus and 40 patients without disorders of carbohydrate metabolism were examined. To study the electrical activity of the expiratory muscles, surface electromyography (EMG) of the external oblique abdominal muscle (OAM), rectus abdominis muscle (RAM), and internal intercostal muscles (IIM) was performed using a functional test with a static expiratory effort. Results. When performing a functional test with a static expiratory effort in both groups, a decrease in the frequency and an increase in the amplitude of EMG was observed, however, in patients with type 2 diabetes mellitus, these changes were less pronounced. There were also differences in the dynamics of changes in EMG indicators. In patients with type 2 diabetes mellitus, the decrease in the frequency of EMG OAM began from 10 seconds of the test, IIM – from 15 seconds, in the comparison group – from 5 and 10 seconds, respectively. The OAM EMG amplitude in the main group did not change significantly, in the comparison group it increased from 5 seconds of expiratory effort. At the 10th second of the test, the amplitude index of the EMG OAM in patients with type 2 diabetes mellitus was 10.4% lower (p=0.027) than in the comparison group, and at the 15th second – by 10.5% (p=0.033). Conclusion: The change in the electrical activity of the expiratory muscles in patients with type 2 diabetes mellitus is due to the slowed down dynamics of the frequency-amplitude characteristics of the EMG OAM, uncompensated IIM fatigue, as well as lower values of the OAM EMG amplitude when performing a functional exercise test with a static expiratory effort.

Aim. To determine the structure and detection rate of some opportunistic infections in premature birth.Materials and methods. The study was carried out at the premises of the Research Institute of Maternity and Childhood Protection and the Pathology Department of the Khabarovsk Perinatal Center. We studied 62 placentas from women whose pregnancy ended prematurely and placentas and organ samples (heart, lungs, liver, and kidneys) from 14 premature infants who died in the early neonatal period. Thirty placentas of women who delivered full-term live babies were classified as a control group. Genomes of Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma species (Ureaplasma urealyticum + Ureaplasma parvum), Cytomegalovirus, Herpes simplex virus, Human herpesvirus 4 type, Human herpesvirus 6 type, Parvovirus B19, Listeria monocytogenes, Streptococcus agalactiae, Streptococcus species, Streptococcus pyogenes, Haemophilus influenza, Klebsiella pneumoniae, Candida albicans were detected by polymerase chain reaction (PCR) in samples of placental tissue and samples of internal organs of deceased newborns. Results. The rate of opportunistic agent detection in the placentas from women with preterm birth made 59.6% and in the sectional material from premature newborns who died in the early neonatal period (78.6%), which figures exceeded the same indicator in the control group (30.0%) respectively, by 2.0 (p=0.007) and 2.6 (p=0.002), respectively. In 47.9±7.2% of cases of all positive results, the material from women with preterm birth presented with various combinations of two, three, and four infectious agents, having common pathogenic links, which contributes to the aggravation of pathogenic processes, comorbidity or multimorbidity. According to the detection rates, in terms of total monoinfections and mixed infection components, pathogens detected during preterm birth were distributed as follows: U. urealyticum ‒ 34,2±5,4%; S. agalactiae ‒ 17,1±4,3%; M. hominis ‒ 15,8±4,1%; S. species (S. sanguis, S. salivarius, S. mitis, S. mutans) ‒ 13,1±3,8%; Cytomegalovirus ‒ 11,8±3,7%; Human herpesvirus 4 type – 9,2±3,3%; M. genitalium ‒ 2,6±1,8%. Conclusion. PCR testing showed that placentas from women whose pregnancy ended prematurely and samples of placenta and organs of premature infants who died in the early neonatal period presented with opportunistic agents colonizing female genital tract (streptococci, mycoplasmas) or ubiquitous herpesviruses persistent and reproduced in human lymphocytes (Cytomegalovirus, Human herpesvirus 4 type). Associations of microorganisms that cause comorbidity or multimorbidity account for a significant portion of the infectious agents detected. The context for a microbiota-integrated opportunistic agent to transform into a pathogenic strain, identification of transformation predictors, and possible tools to correct the disorders – all these require further research.

Published: December 2021

Introduction. The physicochemical properties and the impact on living organisms of nanoparticles and components that make up nanoparticles may differ radically, however, insufficient attention is paid to a comparative study of the toxicity of nanoparticles and constituents of nanoparticles. Material and methods. Biochemical and hematological parameters in the blood of 50 male Wistar rats were determined after a single, seven-fold and thirty-fold intramuscular injection of an aqueous solution of iron-molybdenum nanocluster polyoxometalates (POM) and a mixture of the POM components at a dose of 1.5 mg/kg. A solution of a POM components’ mixture was obtained by the destruction of POM with an increase in pH, followed by neutralization, since POM are unstable in an alkaline medium. Results. The introduction of POM did not cause deviations from the norm in the activity of AST, ALT, total alkaline phosphatase and its bone isoenzyme, α-amylase, protein content, urea and creatinine, which indicates the absence of cytolytic syndrome, including in the liver and myocardium, no damage to the acinar part of pancreas, changes in bone tissue, preservation of the protein-synthetic function of the liver and the filtering ability of the kidneys. The introduction of a solution of POM components (molybdenum, iron) was accompanied by an increase in the activity of AST, alkaline phosphatase, the AST / ALT ratio after 7 injections and an increase in the last two parameters after 30 injections. The impact of POM is characterized by an increase in the content of hemoglobin and erythrocytes in the blood and less pronounced leukopenia, in contrast to the mixture of POM components. Conclusion. A less pronounced deviation from the norm of biochemical parameters and a lower degree of leukopenia make it possible to assess the effect of POM nanoparticles as less toxic than the action of POM components not organized into nanoparticles.

FEATURES OF THE METHODOLOGY FOR CALCULATING THE VALUATION OF ECOSYSTEM RESOURCES
Authors: Suhina Olena
Published: December 2021

Valuation of natural resources, in particular ecosystem resources, occupies one of the leading places in modern economic theory. It should be noted that all methodological and methodical approaches used in world practice to determine the value of natural resources, in their economic essence evaluate each object of using the nature as a commodity that can be bought, sold, leased, etc. This approach is based on an economic point of view and does not take into account the ecological properties of this resource (for example, forest is evaluated exclusively as wood – raw material for the woodworking industry, and its assimilative and oxygen-producing properties are not taken into account).
In the article we propose a methodological approach to the valuation of ecosystem assets of territorial communities that provide assimilation and oxygen production services to society, which is based on the ecological-economic point of view. The essence of this method is that the valuation of ecosystem resources is determined by the cost of their ecosystem services that they provide to society throughout its life cycle. Moreover, when carrying out a summary valuation of various ecosystem assets (forest, water, land), the latter must be valued by the same (identical) method.
The paper proposes an algorithm and a specific mathematical apparatus that allows to determine the value of any ecosystem resource and on its basis to determine the complex value of ecosystems owned by local communities. Tables of data on the volumes of carbon dioxide absorption by plants of Ukraine, which most intensively assimilate carbon dioxide, on indicators of oxygen release by plants and on the duration of the life cycle of certain species of trees and shrubs. It is these indicators can be used as performance characteristics in the proposed mathematical apparatus in the valuation of ecosystem assets. It is noted that the availability of valuation of ecosystem assets will allow, both at the state and local levels, to make appropriate management decisions on their effective use.
