Authors: Bebezov B. Kh. , Sultangaziev R. A. , Abdykadyrov T. A.
Published: July 2022

Background. Portal hypertension-triggered oesophageal and gastric variceal bleeding is the most dangerous and threatening complication, with an up to 50–70 % mortality at first episode. High-mortality repeated bleeding develops subsequently in 30–50 % patients, with the proved 100 % recurrence rate in the first two years following the first episode. The world experience dictates further research to continue towards developing new surgical methods and approaches.

Aim: to evaluate the treatment efficacy of pneumatic endoscopic band ligation of bleeding oesophageal varices (OV).

Materials and methods. The experience of applying pneumatic endoscopic ligation treatment in the patients managed at the General Surgery Unit of the Clinical Hospital of the Kyrgyz Republic Presidential Administration during 2017–2019 was analysed. Endoscopic ligation is a modern minimally invasive and less traumatic intervention used to markedly reduce mortality and improve quality of life in patients with portal hypertension syndrome. The evidence on 76 patients following endoscopic OV ligation was summarised. The patient age ranged from 11 to 70 years (mean 46.26 years); 40 men (52.6 %) and 36 women (47.4 %) were included. Among the 76 patients, portal hypertension was caused by viral cirrhosis in 38, hepatitis B in 5, delta agent hepatitis B in 18, hepatitis C in 13, a hepatitis B–C combination in 1 and a delta agent hepatitis B — hepatitis C combination in 1 patient. In 21 patients, cirrhosis was of unknown aetiology. A portal vein malformation was observed in 13 people of whom 4 had it combined with thrombosis.

Results. A total of 94 ligation procedures were performed in 76 patients with grade II–III OV. Some patients needed to undergo the procedure several times, 18 patients had 2 sessions. Two cases required 3 and 4 sessions each. Moderate oesophageal soreness was reported in 32 patients for 1–6 days following the ligation. No complications were registered during the operation. In early postoperative period, 2 patients developed recurrent bleeding, with haemostasis re-achieved by a repeated vein ligation below bleeding.

Conclusion. Hence, small invasiveness and minor traumatism coupled with high efficiency and lesser complications render endoscopic ligation the method of choice in primary and secondary prophylaxis and treatment of OV. Endoscopic ligation improves the patient’s quality of life, allows an extra time for conservative treatment and longer period to liver transplantation.

Published: July 2022

Background. Current issues in the cytological assessment of cervical epithelium can hamper differential diagnosis of high-grade squamous intraepithelial lesion (HSIL) and cervical cancer.

Aim. To determine the informativity of locally estimated values of odd-numbered higher fatty acids as differential markers in HSIL and cervical cancer.

Materials and methods. Previous original data on the higher fatty acids content in cervical biopsy of primary pre-treatment HSIL and cervical cancer patients were analysed retrospectively. The study cohorts: clinical cohort I — 30 HSIL patients; clinical cohort II — 45 primary stage I squamous cervical cancer patients. Statistical methods included the analyses of ROC curves, sensitivity (Se), specificity (Sp) and accuracy (Ac).

Results. Among all odd-numbered higher fatty acids, the following molecular markers (local thresholds) are differential for cervical cancer: C15:0 ≤1.91 %/cell (Se = 0.81; Sp = 0.84; Ac = 0.83; AUC = 0.81); C15:1 ≤1.72 %/cell (Se = 0.96; Sp = 0.91; Ac = 0.92; AUC = 0.96); C17:0 ≤2.95 %/cell (Se = 0.94; Sp = 0.93; Ac = 0.97; AUC = 0.97); C17:1 ≤1.11 %/cell (Se = 0.96; Sp = 0.98; Ac = 0.96; AUC = 1.0); C19:0 ≤1.17 %/cell (Se = 1.0; Sp = 1.0; Ac = 1.0; AUC = 1.0).

Discussion. Tumour cells are known to possess atypical metabolism, which produces large amounts of higher fatty acids with odd numbers of carbon atoms. The study focused on the value of locally estimated odd-numbered higher fatty acids as differential molecular markers in HSIL and cervical cancer.

Conclusion. The results suggest that C19:0 estimates are applicable in diagnosis of HSIL and cervical cancer.

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used as an electron donor to TiO2 nanoparticles and uses an electrolyte as an electron transport medium. One of the dye extracts of purple spinach and moringa leaves used as a photosensitizer is chlorophyll extract or anthocyanin. The nature of chlorophyll which is able to absorb light is a function of the dye in DSSC. Making Moringa leaf and red spinach leaf dye after being blended, dried and ground into powder. Then the Moringa leaf powder was mixed with 70% ethanol with the ratio of Moringa leaves and ethanol, namely 1:2, 1:3, and 1:4. Meanwhile, red spinach leaf powder was mixed with ethanol solution in a ratio of 1:3. DSSC fabrication shows that the voltage, current, and power produced increases with the increasing amount of ethanol used, namely 1.879 mW, 1.573 mW, and 1.98 mW. Meanwhile, red spinach leaves mixed with ethanol in a ratio of 1:3 showed that the results were higher than Moringa leaves. So from the results of DSSC Solar Cell fabrication using Moringa leaves and red spinach leaves, it shows that there is light absorption from these materials and an increase in the conductive properties of Moringa and red spinach DSSCs.

The pyrolysis reactor is a tool that functions to decompose organic compounds from biomass materials which is carried out by a heating process without or little air with temperatures ranging from 300-600°C. The results obtained from the pyrolysis reactor process are charcoal and liquid smoke. The existing air will accelerate the process of biomass oxidation, but if there is excess air it will cause combustion of the biomass so that most of it will be oxidized and decomposed into smoke and this will cause less charcoal yield. However, without air, the pyrolysis process will take longer. Therefore, an ideal air requirement is needed so that the effectiveness of this biomass pyrolysis process can be maintained because it will produce optimal charcoal and liquid smoke. The purpose of this research is to find out how many air pipes for the pyrolysis reactor are needed in this combustion process and how long the time and temperature of the pyrolysis process combustion and how much charcoal and liquid smoke are obtained. This research was conducted at the Mechanical Engineering Laboratory of the University of Muhammadiyah Metro, this study used a pyrolysis reactor with a diameter of 40 cm, height 50 cm, air pipe diameter inch with variations in the number of 1,3 and 5. Using 8 kg of corncob biomass. Straight pipe condenser with 12 mm diameter copper material 3 m long, outer pipe diameter 4 inch. The results showed that the highest pyrolysis temperature in air pipe 5 was 485°C with a pyrolysis process time of 120 minutes and the lowest temperature in pipe 1 was 353°C with a pyrolysis process time of 185 minutes. The results of the most liquid smoke in air pipe 5 are 0.5 liters or 6.25% and the least liquid smoke results are in air pipes 1 as much as 0.32 liters or 4.0% For the highest charcoal yields in air pipes 1 weighing 4 kg or 50% and for charcoal yields at least on air pipe 5 of 3.2 kg or 42.5%. The highest pH level in the air pipe 1 is 3.43 and the lowest level in the air pipe is 3.11.

"The subject of this article aims to put in the mirror two fundamentally different musical genres. It is the stylistic difference that seems interesting, so in the following pages, I chose to analyze rock creations that quoted or processed classical music. Rock music, a genre that appeared in the second half of the twentieth century, could not escape the influence of classical music, so, as we will see throughout the paper, there are many rock pieces influenced by classical scores, works that remained in the top of the preferences of rock music listeners. Some of the rock musicians chose to quote classical fragments, others chose to process them, or to be inspired by certain elements of their composition, such as melody, harmony, and rhythm. I believe that this type of comparative analysis is helpful in the case of music education teachers who want to introduce the classical genre in the students' favorite repertoire, through the medium of rock music. Thus, the second objective of this article is to propose an alternative to traditional music auditioning. Keywords: rock, comparative analysis, rock cover, audition. "

"Significantly penetrating the years between the two world wars, this situation testifies to the long process of uneven development of Serbian music. Despite the founding of the Belgrade Opera (1920), the gradual growth of performing qualities, the expansion of the repertoire, the premiere of the first Serbian musical and dramatic achievements of modern expression, the influence of popular music remains an almost exclusive privilege of traditional national forms of music. In order to establish internal continuity, they modernized and expanded the existing tradition with new genres, appreciating that sudden new leaps in language can be accepted primarily in those genres that have already gained some continuity in national music. Keywords: modernism, serbian, tradition, nationalism, genres. "

Published: July 2022

"Jeux d’eau, created in 1901, is Ravel’s first piano masterpiece, that of a 26-year-old composer who has just left the Conservatoire. The work surprises with the charm of writing, the playfulness of expression, the maturity of creative thinking and the complexity of elaboration. Beyond the fact that it marks a turning point in Ravel’s career, it is no exaggeration to say that it is both a milestone for piano literature in general and for the impressionist one. Our study focuses on the analysis of Ravel’s writing style and construction in the mirror of musical Impressionism, pointing out, where appropriate, the innovations that foreshadow representative compositional solutions for the avant-garde of the first half of the 20th century and beyond.

Si algo recordamos de nuestros momentos infantiles esos son los cuentos. En el presente trabajo se presenta una intervención educativa desarrollada con alumnos del Grado de Educación Infantil de la Universidad de Valladolid puesta en práctica en el curso 2019-2020. Dicha práctica tenía doble intención. Por un lado, desarrollar el conocimiento del contenido matemático que los futuros profesores de Educación Infantil deben dominar y, por otro, mostrar nuevas formas de presentación de la materia adaptadas a los tiempos actuales sin olvidar lo que se ha trabajado, con buenos resultados, ahora y siempre. Hemos trabajado con la herramienta Twitter, una red social, que permite ofrecer a los padres una continuación del trabajo en el aula. Como resultados, 9 cuentos donde el contenido matemático desarrollado toca todos los contenidos del Real Decreto anterior con cierta tendencia a evitar el contenido de la medida y donde los dibujos son adecuados en los momentos iniciales del desarrollo del cuento, pero no así en los momentos finales en donde la información visual debe informar sobre el porqué del error.

Obviamente, Barrio Sésamo y sus inseparables Teleñecos (Muppets), no entra dentro de lo que se consideran dibujos animados en el sentido estricto. Sin embargo, fue la primera producción televisiva orientada al público infantil con un objetivo educativo serio y la sección quedaría huérfana sin haberse acercado a ella. No en vano, en su diseño y guionización participaron expertos e investigadores desde el comienzo. Aunque son varios los Teleñecos que abordan cuestiones matemáticas, dedicaremos el artículo al Conde Draco (Count von Count), especialista en todo lo relativo al conteo.

Utilizing case study to understand elementary geometry: A practical approach
Authors: Notolegowo Hantoro Ksaid
Published: July 2022

In contrast to the branches of mathematics in general that require only analytical skills through formula calculation, geometry requires other skills in the form of visual ability to understand. The student's analytical skills can be enhanced by theoretical learning methods. However, theoretical learning method will not be optimal in improving the visual ability. Another method is required that can encourage students' analytical and visual abilities. The learning method that suits these needs is a case study. The case study method in geometry lessons can be applied by creating scenarios that are divided into two stages: the preparation stage and the implementation stage. The preparation stage is related to the formulation of scenarios of case studies that will be conducted by the students in the field, while in the implementation stage the students conduct direct observation in the field based on the case study scenario at the preparation stage and then present the observation result through the presentation, accompanied by suggestion and evaluation from teachers.

Published: July 2022

Current studies in operating systems focuses on either security or on reliability. However, current or modern OS platforms call for answers that match both styles of requirements. If we build not only best applications but also middleware and OS in a similar way, we can construct systems that not only are inherently stable however also can resist attacks from malicious programs and face up to errors. In this paper, we conduct an exploratory study on Modern OS reliability and security. We examine many real OS failure facts collected from distinct administrative and real time environments and present the results which show a number of the primary reasons of OS failures.

Potential Impacts of Shade Treatments on Dormancy of Overwintering Redbud (Cercis canadensis L.) Trees at Southeastern Nurseries
Authors: Werle C. T. , Witcher A. L.
Published: July 2022

Dormancy accrual is an important process in mitigating the abiotic stressors of overwintering trees at ornamental nurseries, with frost-injured tree crops at heightened risk of ensuing biotic insect and disease attack. As mean global temperatures rise, overwintering nursery crops may lose dormancy earlier. Using potted eastern redbud (Cercis canadensis L.) trees placed under two types of shade cloth, under full sun, or in walk-in coolers, we measured stem, air and root zone temperatures, accrual of chill hours and mean time to bud break at two sites. While there was no significant difference between the two shade treatments, shade cloths did moderate both high and low temperatures to which trees were exposed. Differences in mean time to first bud break were observed from shaded trees versus those in full sun at each site. It may be useful to alter our shading design to continue protection from overnight lows while preventing excess warming from daytime highs, and thus promoting dormancy and preventing frost exposure in some regions, but further tests will be required.

Species used in this study: eastern redbud (Cercis canadensis L.).

Introducción: La ergometría deportiva realizada a los boxeadores permite valorar los parámetros fisiológicos, utilizados como indicadores del rendimiento físico. Objetivos: Rediseñar protocolos ergométricos específicos para el boxeo y aplicar el software CARDIOTRAINING_CIDC, en beneficio de la planificación deportiva individualizada. Material y método: Estudio retrospectivo longitudinal, entre abril de 2020 y abril de 2021; muestra: 14 boxeadores del Equipo Nacional cubano; edad: 24 a 31 años, todos del sexo masculino. Se realizaron dos tipos de pruebas de esfuerzo máximas sobre estera rodante: una convencional y otra específica para boxeo. Se utilizó un software, el CARDIOTARINING_CIDC, una macro VBA de Excel, para calcular y archivar los valores de la frecuencia cardíaca. Resultados: Se registraron en la primera y segunda ergometrías: la frecuencia cardíaca máxima y su porcentaje respecto a la estimada; el consumo máximo de oxígeno (medias: 45 y 61,4 ml/kg/min), el consumo miocárdico de oxígeno (30,3 ml/min y 41,8 ml/min) y el equivalente metabólico (medias: 12,8 METS y 17,6 METS). Tres de estos indicadores tuvieron relación estadística significativas (p<0,01) en la ergometría diseñada para el estudio, respecto a la convencional. Conclusiones: El rediseño específico de la ergometría para el boxeo resultó más efectivo en la realización de las pruebas de esfuerzo máximas cardiopulmonares.

Authors: Sarafoleanu Codrut , Bejenariu Andreea , Enache Raluca , Patrascu Elena
Published: July 2022

Paragangliomas are tumors of the neuroendocrine system, which arise from the neural crest and chemoreceptor cells. They can be found in the adrenal gland, in the aortic arch, in the jugular bulb or at the level of the cochlear promoter. Glomus tumors grow slowly, are well vascularized, invasive and locally aggressive. Because of their anatomic relation with the jugular bulb, the internal carotid artery, the facial nerve and the cranial nerves IX, X, XI, XII, the patients may develop important complications. Therapeutic options for head and neck paragangliomas are surgical treatment with endovascular embolization, conventional radiotherapy, stereotactic radiosurgery or a combination of these therapeutic methods.

In case of paragangliomas, it is essential to take into consideration the size and localization of the tumor, in order to establish the proper therapeutic approach, either conservative, radiotherapy or surgical, due to the risk of postoperative nerve palsies, details that we try to cover in this review.

In order to emphasise the importance of correct diagnosis, proper treatment, postoperative complications and postoperative functional recovery in the case of glomus tumors, we present the case of a 35-year-old female who was diagnosed and surgically treated for a right jugulotympanic paraganglioma. The postoperative cranial nerve injuries involved VII, IX and X nerves and the patient followed multiple protocols of functional recovery for the affected nerves. After specific therapy, the patient partially recovered the function of the right facial nerve; deglutition and voice were significantly improved.

Published: July 2022

The objective was to conduct a comparative analysis of the dynamics of biomarkers of apoptosis and autophagy in the eripheral blood of patients in the acute period of ischemic stroke (IS) and compare it with the dynamics of the severity of neurological deficit according to the NIHSS (National Institutes of Health Stroke Scale) and the volume of the brain lesion according to the results of magnetic resonance imaging (MRI). To assess the role of the studied parameters in the prognosis of the outcome of the acute period of the disease.

Methods and material. We examined 56 patients in the acute period of newly developed atherothrombotic IS. The control group consisted of 29 healthy donors. Patients underwent a dynamic clinical and neurological examination on the 1st, 7th and 14th days from the onset of the disease. At the same time intervals, the dynamics of the expression of biomarkers of apoptosis and autophagy in peripheral blood was evaluated by flow cytometry and compared with neurological status indicators on the 1st, 7th, and 14th  days, respectively, using correlation analysis.

Results. A statistically significant increase in the expression of annexin V and caspase-3 compared with the control group was observed throughout the study in all populations of leukocytes with a maximum increase in the first 24 hours. Increased expression levels of annexin V and caspase-3 positively correlated with the severity of neurological deficit and the amount of brain damage on the 1st and 7th days. A direct correlation was found between increased values of autophagy biomarkers LC3, Cyto-ID, the amount of brain damage, and the severity of neurological deficit on the 7th day.

Conclusion. A statistically significant increase in biomarkers of apoptosis and autophagy in the peripheral blood in the acute period of IS correlates with the severity of clinical and neurological parameters. The role of a significant increase in caspase-3 as a predictor of adverse disease outcome requires further study.
Developing the theory of formation of enterprise’s efficient portfolio of financial resources on the basis of clustering the elements of its structure
Authors: KHLYNIN Eduard V. , VASIN Aleksandr S. , SABININA Anna L.
Published: July 2022

Subject. We consider a portfolio of financial resources as a complex money system generated from various sources of economic activity financing. It is used to fund business goals of the enterprise and includes financial resources with various cost characteristics, level of financial risk, term of use, and other key parameters.
Objectives. The aim is to underpin the viability of cluster approach as a methodological tool for developing the theory of formation of efficient portfolio of financial resources through formulation of tenets and theoretical trajectories of movement for various clusters of financial resources.
Methods. The study rests on the cluster approach to simulate the process of financial portfolio formation. We apply basic provisions of the systems theory and the theory of economic growth and development.
Results. We performed clustering of financial resources by type of sources of finance, formed a structure of clustering matrix, and formulated criteria of positioning the financial portfolio of the enterprise. The paper determines trajectories of movement of typical clusters of financial resources and possible alternative financial strategies, resulting in changes in the key parameters.
Conclusions. If implemented, the cluster approach enables to expand the theoretical base used by financial managers for building an efficient portfolio of financial resources, and to meet the requirements for cost, risk, and stability of the latter, during the entire period of formation.
Production and Reserves of the World's Leading Publicly Traded Oil and Gas Corporations
Authors: SHIMKO Oleg V.
Published: July 2022

Subject. The article considers the production and proved reserves of the twenty five leading publicly traded oil and gas companies from 2006 through 2018.
Objectives. The aim of the study is to determine the current level of values of the production and proved reserves of leading publicly traded oil and gas companies, as well as to identify key trends in their changes during the study period, to establish the factors that led to the changes.
Methods. The study rests on methods of comparative and financial-economic analysis, as well as generalization of materials of consolidated income statements.
Results. The paper established a practically commensurate growth in the production of liquid hydrocarbons and natural gas. It determined that most of the total production fell on liquid hydrocarbons. There was an increase in proved reserves, and the component of liquid hydrocarbons gradually reached almost two-thirds in the structure. The growth in the production of liquid hydrocarbons and natural gas outpaced the growth of the corresponding proved reserves in terms of its pace at the level of the world's leading publicly traded oil and gas corporations, and, therefore, there was a general decrease in the level of reserves to production ratio of companies. The indicators of proved reserves to production ratio inherent in the stock market sector of the oil and gas industry are mainly from 10 to 15 years. Therefore, the specified time range is a guideline in assessing the value of proved reserves life of liquid hydrocarbons and natural gas of publicly traded oil and gas corporations. It was determined that the largest publicly traded oil and gas corporations from Russia and Canada managed to strengthen their position in terms of operating indicators in the industry. The situation with production and proven reserves has become noticeably worse for most independent companies from the United States and corporations from China.
Conclusions. It becomes difficult for most independent companies to maintain an acceptable level of proved reserves to production ratio in the face of increasing production by leading oil and gas corporations at current prices for raw materials.
