Published: December 2020

Aim: The random use of antimicrobials for years has led to bacterial DNA mutation and a result of that, bacteria have become resistant to antibiotics. Methicillin-resistant Staphylococcus aureus (MRSA) is among these types of resistant bacteria that can easily infect when the immune system of the host is suppressed, and it significantly delays the wound healing. Different treatment methods are being investigated to overcome this problem. Antimicrobial photodynamic therapy is a candidate to become an alternative treatment for the destruction of MRSA. The aim of this study was to investigate the effect of chlorin e6 for the photoinactivation of MRSA and the synergetic role of ethanol in this mechanism.
Methods: 655 nm laser light and Chlorin e6 as photosensitizer were examined for the photoinactivation of MRSA. Besides, 20% ethanol was used to increase the total antimicrobial efficacy with lower light energy densities and photosensitizer concentrations. The colony counting method was used to determine viable bacterial cells after each application.
Results: 25 J/cm2 energy density with 20 μM Chlorin e6 and 50 J/cm2 energy density with 10 μM Chlorin e6 showed the highest bactericidal activity. When 20% ethanol was used as an adjuvant, 25 J/cm2 energy dose with 2 μM Chlorin e6 resulted in a better killing effect.
Conclusion: Chlorin e6-mediated photodynamic therapy was successful to destroy MRSA and the addition of ethanol provided the opportunity to obtain higher antibacterial activity with lower light intensities and photosensitizer concentrations.

Published: December 2020

This paper studies the features of the circle of Willis and cerebral aneurysm in patients with cerebral aneurysms through films of Multi-slice Computed Tomography (MSCT) at the Department of Radiology, Bach Mai Hospital, from March 2017 to March 2018. The study results show that female/male ratio was 2.37: 1; the number of patients with only one aneurysm accounted for 90.68%; Saccular aneurysm was more common than lozenge-shaped aneurysm; the rate of aneurysm ruptures was 82.35%; the bulge was mainly distributed in the carotid artery (94.6%). The very small bulge (less than 3mm) and the small bulge (3-7mm) were most common and accounted for 33.33% and 49.62%, respectively. The variations of the circle of Willis were very diverse and complex, including 13 forms, four of which were the circle of Willis anterior part variants and nine transformations were the circle of Willis posterior variants. Abnormalities (aplasia, hypoplasia) of the anterior communicating arterial were 8.48% and abnormalities of the posterior communicating arterial were 82.6%. The paper concludes that the abnormal anatomical variations in the circle of Willis can facilitate the early diagnosis and treatment of cerebral aneurysm disease.

The study aimed at revealing the extent of achieving the goals of civic education in the light of the concept of globalizationin the curriculum of the civic and national education of high elementary schools from Aqaba teacher’s perspective. The study population consists of all the teachers of the social studies in elementary schools at Aqaba Governorate for the year (2019-2020). It consists of 49 teachers distributed in 17 schools. The study tried to answer the following questions:

To what degree the goals of civic education in the light of the concept of globalization in the curriculum of the civic and national education from Aqaba teacher’s perspective can be achieved?
Are there any statistical difference in the teacher’s evaluations to achieve thecurriculum of the civic and national education based on gender and level of education?

The study tools were a test and a questioner that measures the teachers’ view of the extent of achieving the goals of civic education in the light of the concept of globalization. Therefore it was divided into two parts one pertaining the citizenship values and the other one pertaining the goals of globalization. The researcher got the arithmetic averages and the standard deviations for each paragraph and for each field of the study. The stability coefficients of the study were measured individually in addition to the questioner coefficient of stability as a whole which was (0.78). The globalization stability coefficient was (0.78) and the civic education was (0.896) all of which are high and accepted stability coefficients. The arithmetic averages and the standard deviations were measured for the two parts of the study. It was noticed that the civic education got the lowest arithmetic average (3.01) and a standard deviation (0.91). As for the second part namely the globalization that got the highest arithmetic average (3.29) and a standard deviation (1.16). The researcher believes that the awareness of civic education and the goals of globalization are very important and should be included in the curriculum. Both come in accordance with the study conclusion.

Authors: Kuz’min A. Yu. 
Published: December 2020

The study is devoted to the development of accounting procedure and recording the financial results of bonds with a double currency denomination in accordance with International Financial Reporting standards (IFRS). The methodological base of the research includes system and dynamic-situational analysis, evaluation models of financial mathematics, accounting procedures of the theory of financial accounting. Based on the assumptions made at the formal mathematical level, this procedure is fully algorithmized, despite the ambiguity or impossibility of direct assessment of such basic accounting indicators as the initial estimate, the internal effective interest rate, and the amortized cost of a financial instrument. Considerable attention is paid to the issues of mathematical evaluation and reflection of financial results when preparing financial statements in accordance with the concept of amortized cost and effective interest rate, taking into account the impact of changes in the currency component in dynamics. The originality and uniqueness of the developed procedure is that it is applicable to the situations where coupon payments are paid several times a year. The theoretical and practical significance of the research is determined by the development of scientific and applied tools that include accounting and process models, evaluation algorithms and procedures that can be used by accounting and audit departments in practical work when solving problems of reporting in accordance with IFRS.
COUPLING OF TWO UNIFORM FLOWS

Published: December 2020

The authors consider the problem of coupling two two-dimensional in terms of turbulent potential uniform flows. The flow movement is considered in a smooth horizontal channel with relatively short length of watercourses, when the flow resistance forces can be ignored. The main task is to determine the most rational form of the side walls of the flow interface.
Radial spreading of a turbulent flow can be one of the main types of General flows for coupling various forms of flow. First, the flow is transferred through a simple expansion wave to a radial one, then through a simple compression wave it is transferred to a uniform flow. The solution of the problem with this formulation allowed us to improve and update the solution of problems on the coupling of flows.

Published: December 2020

Tracer technology has been used in the oil industry to investigate the fluid flow behavior into the reservoir. Using this technology is possible to obtain relevant data from the reservoir such as remaining oil accumulations, estimate volumetric sweep efficiency, define reservoir heterogeneities, identify flow channeling, and determine residual oil saturation (Sor).

This technology has been one of the most useful tools for reservoir characterization for several decades. The tracer is injected in the injector well and then monitored in the producer wells through the tracer concentration measurements. Although many tracer studies have been documented for reservoir characterization, the available information and methodologies related to the design, implementation, and interpretation of tracer tests are limited or confidential.
The goal of his article is to show a methodology for the design, execution, and interpretation of interwell tracer tests, which includes procedures for field implementation, sampling, and monitoring of these tests. Laboratory analysis using ultra-high-performance liquid chromatography is described in the experimental evaluation of tracer tests. Additionally, for a better understanding of the technology, examples of laboratory and field cases are presented.

Published: December 2020

Indian art is a vivid presentation of various forms of nature. In many ancient cultures trees are treated with acclaim and affection but in India treated with reverence and love. The concept of tree, as a symbol of life, of eternity and resumption is as old as humankind. The environmentalists evaluate their importance for the world's ecosystem as they are used in numerous ways in everyday life but their aspect is that they are the symbol of divinity of nature with beauty and cultural values.
Nature with its qualities helps the creatures in their survival. The beauty of nature can be perceived in its utility and man can pay his attributes with the awareness towards the protection of nature.

Questões energéticas e ambientais tornaram-se pautas bastante discutidas em reuniões ao redor do mundo devido às alterações climáticas que vêm crescendo com o passar dos anos. Após a revolução industrial, profissionais da construção civil se viram diante do surgimento de novos materiais e novas formas de se projetar. Nesse contexto surgiram muitas estruturas similares em todo lugar, como as edificações com fachadas espelhadas que se multiplicaram, contribuindo com a perda de identidade de alguns locais, uma vez que este tipo de projetar ignora as características climáticas e culturais de onde são realizadas as construções. Consequentemente, medidas precisaram ser adotadas para que os indivíduos desses locais conseguissem se sentir bem, com a adoção de sistemas de ar condicionado utilizados a fim de manter os usuários dessas megaestruturas satisfeitos termicamente. Porém, com as questões ambientais e mudanças climáticas é papel dos profissionais da Engenharia Civil e Arquitetura intervirem quanto à adequação das edificações ao conforto e, por conseguinte, à produtividade dos usuários, visando à eficiência energética desses locais em segundo plano. Assim, a análise do ambiente construído quanto ao desempenho térmico do mesmo tem como objetivo avaliar o ambiente interno, descobrir se encontra-se na zona de conforto, e em caso negativo, propor mudanças capazes de atenuar o estresse térmico que ali se encontra. O presente trabalho foi desenvolvido com o objetivo de avaliar o desempenho térmico da cozinha do Restaurante Universitário (RU) da Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM) - Campus Mucuri utilizando uma aplicação desenvolvida a partir do método Centre Scientifique et Technique du Batiment (CSTB). O resultado final da avaliação sugere a adoção de alternativas capazes de tornar o ambiente um local termicamente confortável para a realização das atividades ali executadas.
Analysis of Risk Factors for Acute Heart Failure in Patients with Dilated Cardiomyopathy and Persistent Severe Functional Mitral Regurgitation Despite Cardiac Resynchronization Therapy
Authors: Buriak R. V. , Rudenko K. V. , Krykunov O. A. 
Published: December 2020

Congestive heart failure resulting from non-ischemic dilated cardiomyopathy (DCM) with secondary functional mitral regurgitation (FMR) is associated with poor prognosis. Medical treatment results in a 1-year survival of 52% to 87% and a 5-year survival of 22% to 54%, with highest survivals observed in more recent years, probably reflecting improvements in medical therapy. Non-surgical interventions involve cardiac resynchronization therapy. In addition to medical treatment, cardiac resynchronization therapy (CRT) should be considered in patients with New York Heart Association (NYHA) class II– IV HF, left ventricular ejection fraction (LVEF) =35%, normal sinus rhythm and left bundle branch block with QRS >150 ms. In these patients, CRT can also facilitate left ventricular (LV) reverse remodeling and reduce associated FMR.
The aim of this study was to investigate the features of symptomatology and to analyze the risk factors for acute heart failure (AHF) in patients with DCM and persistent severe functional mitral regurgitation despite CRT and optimal guideline-directed medical therapy (GDMT).
Materials and methods. After providing informed consent, 144 patients with severe FMR were involved in the study. Concomitant tricuspid valve regurgitation was registered in 142 (98.6%) cases. The median LVEF was 27.0 (23.0-31.6)%. 40 (27.8%) patients had a permanent form of atrial fibrillation, and 24 (16.7%) patients had a first-degree atrioventricular node block. The median NT-proBNP was 2600 (2133-3200) pg/ml, indicating the presence of severe chronic heart failure.
Results. The median term after CRT device implantation was 36 (3.5-60) months. A comparative analysis between DCM patients with and without CRT revealed statistically significant differences between clinical characteristics, namely: age (p=0.020), lower heart rate (p=0.004), lower hemoglobin (p=0.017), higher erythrocyte sedimentation rate (ESR) (p=0.000) and more frequent AHF at the hospital stage (p=0.030). The incidence of AHF at the hospital stage was 13.8% in patients with CRT and 3.5% in those without CRT. The calculated odds ratio of AHF was 4.44 (95% confidence interval (CI) 1.039-18.971), and the relative risk of AHF was 3.966 (95% CI 1.054-14.915).
Discussion. FMR has been reported to persist in about 20% to 25% of CRT patients and, in an additional 10% to 15%, it may actually worsen after CRT. In this subset of CRT non-responders, reduced reverse remodeling, increased morbidity, and increased mortality have been reported compared with CRT patients in whom FMR was significantly reduced or abolished.
Conclusions. The results of our study demonstrate that severe functional mitral regurgitation despite cardiac resynchronization therapy in patients with dilated cardiomyopathy is a significant risk factor for AHF and subsequent hospitalizations for heart failure.
Case Study: Using 3D Speckle Tracking Echocardiography for Left Ventricular Aneurysm Diagnosis

Published: December 2020

Nowadays magnetic resonance imaging (MRI) is a gold standard for diagnosing abnormalities of left ventricular geometry and function, however, it is not universally accessible. Furthermore, MRI is not compatible with pacemakers and similar devices. 3D speckle tracking echocardiography (3D STE) is a cutting-edge echocardiography imaging technique for myocardial deformation assessment. As such, 3D STE looks very promising for diagnosing structural complications of myocardial infarction (MI) and choosing the optimal surgical techniques.
In this case study, we used 3D STE to assess left ventricular function in a patient with left ventricular aneurysm.
The patient was admitted to National Amosov Institute of Cardiovascular Surgery three weeks after having a second MI (the first MI was reported 4 years ago). His coronary angiography showed diffuse coronary artery disease. 2D echocardiography (performed on Toshiba Artida) results: end-diastolic volume (EDV) 206 ml, end-systolic volume (ESV) 141 ml, ejection fraction (EF) (Simpson’s method) 31%. An object sized 2.2*1.6 cm was discovered in the apical region (left ventricular thrombus). 3D STE results: EDV 209 ml, ESV 182 ml, EF 13%. Global area strain (GAS) was considerably decreased (–13.7 %) showing the pattern of ischemic cardiomyopathy with multivessel disease. Due to several reasons, it was impossible to obtain an MRI scan, so a CT coronary angiography was performed (Toshiba Aquilion One). The results of multi-slice computed tomography (MSCT) were consistent with those of echocardiography.
According to the results, the initial plan to resect the apical akinesia region was ruled out. The patient underwent coronary artery bypass grafting (CABG) (4 shunts), the removal of thrombi from the left ventricle (additional fresh thrombi were discovered during the surgical intervention), and left ventricular aneurysm repair under cardiopulmonary bypass. Post-treatment 3D STE results: EDV dropped to 135 ml, EF rose from 13% to 32%. GAS increased up to –20.4 %, while the strains of all segments increased to subnormal levels. The overall dynamics was positive, and the patient was discharged to undergo postoperative rehabilitation.
The case shows that 3D STE data is consistent with CT data in patients with abnormal ventricular remodeling. 3D STE is a good method for differentiation between akinetic scar tissue and a dyskinetic left ventricular aneurysm.
