Published: December 2020

Background: Presence of biofilms in sinus mucosa of patients with chronic rhinosinusitis (CRS) remains controversial. Literature shows that biofilms may contribute to the recalcitrant nature of CRS and unfavourable outcome following surgery. This study was performed to evaluate the prevalence of biofilm and its clinical and histopathological impact in patients with chronic rhinosinusitis with nasal polyps (CRSwNP)

Methods: 41 patients of CRSwNP (study group) were included. SNOT-20(sinonasal outcome test-20) score, radiological and endoscopic findings of these patients were evaluated preoperatively. Sinonasal polypoidal tissues removed during surgery were studied for the presence of biofilm and evaluated histopathologically. Postoperatively SNOT-20 score and endoscopic finding were recorded. 41 patients undergoing septoplasty for deviated nasal septum (control group) were also included in the study. Sinonasal mucosal samples of these patients were analysed for the presence of biofilm.  

Results: 29 out of 41 (70.73%) samples in study group and 9 out of 41 (21.9%) samples in control group were positive for biofilm. We found a significant impact in preoperative SNOT-20 symptom scores in biofilm positive study group. But there is no significant impact in preoprerative endoscopic scores, radiological scores and postoperative SNOT-20 scores and endoscopic scores in study group patients irrespective of biofilm status.

Conclusions: Prevalence of biofilm in patients with CRSwNP was higher than normal population. Biofilms plays a major role in preoperative symptomatology. But biofilms have no endoscopic, radiological, and histopathological impact in CRSwNP. It was concluded that apart from biofilms, host and other environmental factors plays a major role in the pathogenesis of CRSwNP.

Background: Tinea corporis and cruris are estimated to affect 22% to 55% of the Indian population. This real-world study was conducted to evaluate the effectiveness and safety of eberconazole 1% cream among Indian patients.

Methods: In this prospective, single-arm, observational study, patients with Tinea corporis and cruris aged ≥18 years were prescribed eberconazole 1% cream (Ebernet®, Dr. Reddy’s Laboratory, India) for up to 3 weeks. The primary endpoint was proportion of patients with improvement in total signs and symptoms score with 2 weeks of treatment. The key secondary endpoint was mean percent reduction in individual signs and symptoms score (erythema, itching, scaling) from baseline to the end of the 1st, 2nd, and 3rd week. A post-hoc analysis was performed on a subgroup of patients (completer set [CS]) who reported application of eberconazole 1% cream for 3 weeks in the study. There were no adverse effects reported.

Results: Of 120 enrolled patients;104 (86.7%) were included in the full analysis set (FAS) and 76 (63.3%) patients were included in the CS. After 2 weeks of treatment, total signs and symptoms score<2 was achieved by 25% of patients in the FAS and 28.9% in the CS. After 3 weeks of treatment, mean percent reduction in total sign and symptom score was 60.3% for erythema, 61.2% for itching, and 76.8% for scaling.

Conclusions: The evidence from this real-world observational study and a post-hoc analysis suggests that eberconazole 1% cream is effective and safe treatment option in the management of Tinea corporis and cruris in Indian patients.

Целью исследований являлось обоснование режимов градиентного воздействия постоянного магнитного поля на листья табака, влияющих на процесс их сушки. Выдвинута рабочая гипотеза, что в зависимости от частоты и продолжительности градиентного воздействия постоянного магнитного поля скорость удаления влаги из табачных листьев может снижаться или увеличиваться. Установлено, что градиентное воздействие постоянного магнитного поля на среднюю жилку табачных листьев при высоте расположения магнитов Н = 65 мм оказывает разностороннее воздействие на процесс сушки. При частоте воздействия 0,178 Гц и продолжительности обработки 11,2 сек процесс сушки затормаживается, а при частоте воздействия 0,178 Гц и продолжительности обработки 44,8 сек процесс сушки листьев ускоряется. При высоте расположения магнитов Н = 25 мм наблюдалась тенденция ускорения процесс сушки на 28,8 % (частота воздействия 0,357 Гц; продолжительность обработки 112сек).

Authors:   Professor of the Department of Criminal Procedure of the Ural Law Institute of the Ministry of the Interior of the Russian Federation PhD (Law), Associate Professor, Stelmakh Vladimir Yu.
Published: December 2020

The article analyzes problematic aspects of representation of a legal entity in criminal proceedings. Representatives of a legal person may be all persons listed in the criminal procedure law, but the main representative is a member of the governing body, and the remaining persons are appointed by this body and are additional. Some decisions (for example, an application to initiate criminal proceedings on crimes listed in chapter 23 of the Criminal Code of the Russian Federation) are entitled to be submitted by the governing body as such, and not by its individual members. A distinction is made between the representation of a legal entity in unitary enterprises and joint-stock companies. The possibility of participation of representatives of the owner of a unitary enterprise as a representative of the victim is justified in cases where the director of the enterprise unsatisfactorily performs duties in criminal proceedings or is suspected of committing a crime.

Published: December 2020

The article is devoted to the problems of professional training of Soviet judges during the new economic policy period. The legal normative base of the organization and functioning of legal courses is analyzed, the dynamics of the personnel of the courts by the level of education is traced. The training of justice staff was carried out at legal courses: the highest one-year, regional six-month, short-term (three-month). Circular orders of the Commissariat of Justice defined the content of the educational program of legal courses, the status of student and their material support. The training allowed students of legal courses to become a judge. The big need for judges and the high staff of the court turnover caused a deficit of student to fill the personnel of the courts. By 1929, only 10 percent of judges had theoretical training – graduated from legal courses.

Modeling and prediction of asphaltene-resin-paraffinic substances deposits in oil production wells
Authors: Martyushev Dmitriy A.
Published: December 2020

In the oil industry today, the issue of combating deposits of asphaltene-resin-paraffinic substances (ARPD) remains relevant. At the moment, the most common method in the Perm Territory for removing ARPD in wells operated by electric centrifugal pumps is mechanized (mechanical dewaxing units). This method is the main one in the fight against wax deposits, but does not provide absolute protection. The least costly way to deal with ARPD is the use of flushing with hot oil or water, but this also does not always provide sufficient efficiency. The effectiveness of technologies will depend on the depth of deposition, the intensity and thickness of the formed layer of paraffin deposits, respectively, to select an effective technology for each specific well, knowledge of these parameters is required. To solve this problem, computational hydraulic models were created, hydrodynamic modeling and simulation of paraffin deposits when lifting fluid in a well was carried out using the example of five wells of one of the oil fields of the Perm Territory. Based on the calculations, recommendations were given on the choice of the method for removing and preventing ARPD for the analyzed wells. The proposed measures have been implemented at the wells and to date have led to a reduction in the costs of their implementation and significantly reduced oil shortages. In three wells, the change in annular pressure led to a decrease in foaming and stabilization of the dynamic level, while the main problem was solved – ARPDs are not formed in the annulus.

One of the strategic ways in the development of multilayer fields is to identify the source of water inflow into the well production and, as a result, to eliminate it with subsequent optimization of the production of non-watered formations. A method for assessing the degree of water cut in formations based on the quantitative characteristics of the composition of the produced water is proposed in this article. The study of a wide collection of produced water samples made it possible to trace the change in its geochemical composition depending on the age of formation of the reservoir in the Volga-Ural region.The microelements and macro element composition of water, as well as its isotopic composition were investigated. The water of different layers differs in some of the elements, which are called «key elements». Using the methods of mathematical statistics at 2 reservoir objects operated by a common filter, the incoming water was divided into fractions depending on the geochemical composition. It is shown which of the layers has more water out. The feasibility of carrying out these geochemical studies was confirmed by blocking one of the production wells operating in 2 layers, the most watered interval according to geochemical studies, as a result of which the water cut of the well production decreased from an average of 75% to 4% and is observed for several months, the oil production rate increased from 1–2 t/day to 2.5–3 t/day and remains at a constant level.

Authors: ISIKTAS SAYILAR Emel , ÇELİK Sıla , İNCE Muhammed Emir , ERGÜN İhsan
Published: December 2020

Aim: The aim of this study was to evaluate the association of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with acute rejection after kidney transplantation.
Material and Methods: A total of 36 adult renal transplant recipients (33 males, 3 females) with a median age of 41 (range, 19-64) years were included in this retrospective study conducted between January 2016 and January 2019. Data on patient demographics and laboratory findings (neutrophil, lymphocyte, platelet, creatinine, eGFR, serum uric acid and C-reactive protein) were recorded. Acute rejection was defined via renal biopsy in accordance with Banff criteria.
Results: Acute rejection occurred in 16 (44.4%) patients. NLR (median 3.75 vs. 1.99, p=0.001) and PLR (median 125.59 vs. 99.23, p=0.008) values were significantly higher in the acute rejection group than in the control group. Area under the curve was calculated to be 0.822 for NLR and to be 0.759 for PLR. Cut-off values were determined to be >2.5 (75% sensitivity and 75% specificity) for NLR and to be >108 (81% sensitivity and 65% specificity) for PLR. Univariate analysis revealed a strong correlation of acute rejection both with NLR >2.5 (Odds Ratio (OR)=0.267, 95% Confidence Interval (CI)=0.089-0.803, p=0.019) and PLR >108 (OR=0.231, 95% CI=0.066-0.810, p=0.022).
Conclusion: In kidney transplant patients, there is a strong relationship between high NLR and PLR values and the development of acute rejection. As simple, easy-to-access, inexpensive and non-invasive methods, PLR, and particularly NLR, may be potential tests to diagnose post-transplant acute rejection.

Error Inherent in Simulating Planetary Thermal Effect on the Spacecraft Surface by using Isotropic Planetary Radiation Intensity Field Model Instead of Anisotropic
Authors: Kolesnikov A.V. , Pronina P.F. , Paleshkin A.V.
Published: December 2020

In order to mathematically simulate the thermal effect that radiation emitted by planets has on spacecraft, two intensity field models describing planetary radiation may be used depending on the emitter specifics: isotropic and anisotropic. The isotropic model is based on the assumption that the local surface density of outgoing radiation flux is the same for all surface regions visible from orbit. In the case of the anisotropic model this value is assumed to be proportional to the zenith angle cosine for each surface element on the side of the planet that is illuminated by the Sun. Published results of studies concerning developing planetary radiation field simulators indicate that thermal vacuum installations where the working volume is comparable to the total installation volume can only reproduce the sotropic planetary radiation intensity field model. It is a pressing issue to determine whether and when it is possible to replace the anisotropic model with an isotropic one when physically simulating the effect that the solar radiation reflected from a planet and intrinsic radiation flows generated by planets with no atmosphere have on spacecraft. The investigation that we conducted regarding this issue was based on comparing the results of computing the irradiance of spacecraft elements using the models under consideration. These computation results allowed us to conclude that it is possible to physically simulate the effect of solar radiation flows reflected from planets combined with intrinsic (infrared) radiation flows generated by planets with no atmosphere by means of using simulators reproducing isotropic radiation fields in their working volumes

Authors: Nikolov Valeri , Petkova Miroslava , Nikolov Emil
Published: December 2020

Hypertension is one of the leading diseases of the cardiovascular system. It is manifested by changes in arterial stiffness. Cardiovascular reactivity, especially blood pressure (BP), changes during the cold pressor test (CPT) depending on various factors. Undoubtedly, stress is one of the most important factors. The aim of this study is to investigate the various effects of CPT on cardiovascular responses in healthy young subjects. A total of 56 healthy individuals aged between 21 and 26 years were investigated. The cardiovascular responses (BP, heart rate and aortic pulse wave velocity) to CPT were recorded by using the applanation tonometry. The Medical Outcomes Study Sleep Scale and the State-Trait Anxiety Inventory were used. 32.14% (n = 18) of the individuals who showed differences in systolic BP more than 22 mm Hg and differences in diastolic BP more than 18 mm Hg after the CPT were defined as hyperreactors. Hyperreactors showed a significantly higher increase in sleep disturbances (p > 0.01) and anxiety when compared to normoreactors. The CPT used to diagnose cardiovascular reactivity in young individuals and the assessment of perceived stress can help identify candidates who are at risk of hypertonic disease in the future.

 

Keywords: Cold pressor test, cardiovascular reactivity, applanation tonometry, blood pressure, stress.

The forest tree species that are widely grown to produce pulp and paper raw materials are Acacia spp. and Eucalyptus spp. One alternative species is binuang bini (Octomeles sumatrana) which can be developed for plantations. To maintain high seed viability, it is necessary to know the handling of seeds and control of seed-borne diseases during storage. The purpose of this study was to determine the method of the effective technique to control the seed-borne diseases of binuang bini during seed storage. The techniques for Seed disease kontrol methods in seed storage are carried out using chemical and natural fungicide. The results showed that the pure live seed was influenced by a single factor of fungicide and storage room, interactions between fungicides and storage room, interactions between fungicides and storage periods as well as interactions between fungicides and storage space and storage periods. Seed handling of binuang bini can be conducted effectively and efficiently by storing the seed in refrigerator for 3 months without using fungicides, but it will be better if the seed is given benomil fungicide and stored in airconditioned room (temperature of 18℃-20℃ and relative humidity of 50%-60 %).

The green revolution movement is an action to change people's behavior quickly and precisely to care for environment quality through planting activities in South Kalimantan Province. This movement requires the quality forest tree seed supply, thus requiring research to determine an integrated and systematic strategy for developing forest tree seed programs in South Kalimantan in the next 10 years. SWOT analysis (strengths, weaknesses, opportunities, threats) with the analytical hierarchy process approach is used to determine the planning strategy. The results of the analysis show that the position of forest tree seed implementation programs is in an investment position, which shows a big opportunity but still has internal constraints/weaknesses. Weakness-opportunities strategies were chosen with 6 programs, i.e.: increasing the human resources competence; construction of facilities and infrastructure for seeds and seedlings certification; organizing certification of seed sources, seedling quality and seed quality; development of superior seed sources; strengthening of quality seed and seed production systems; and the provision of technological information, documentation and supervision systems of the seed and seedling distribution. This strategy can be described in a work program which is expected to be able to improve the performance of the forest tree seed implementation in order to provide quality seeds and seedlings and to become a community economic generator from the forest tree seed sector in South Kalimantan.

Published: December 2020

In this article we discuss homology learning that teachers in initial training, participating in the Institutional Program for Teaching Initiation Scholarships - PIBID, achieve in the relationship they establish with teachers of the basic school. The central objective aimed to understand homological learning in the process of teacher education for undergraduate students in Pedagogy, considering the insertion in the school routine, in which educational experiences are learned and apprehended through the process of relating to the other. As a theoretical framework for carrying out the work, we anchor the analytical perspective from the contributions of Silva (2016), Silva (2017), Nóvoa (2002), Tardif (2003), among others. The study is affiliated with the (auto) biographical approach, in which narratives are central elements for understanding what is lived and learned. We use narrative interviews with information collection devices. The results indicate that the licensee who experiences educational practices in school daily life, while participating in PIBID, has the possibility of generating teaching learning, revealing knowledge about his personal / professional development. It is also evident the production of knowledge that emerges from the experience, from the very insertion of the student in the school routine, in which the relationship that the teacher in initial training establishes with teachers in service generates conditions of learning through homology.

To date, in the field of monitoring deformations of the earth’s surface in the area of opencast mining, there is almost no current regulatory and methodological documentation that regulates the conduct of observations and at the same time takes into account the features of existing mining facilities of opencast mining and the possibilities of modern survey technologies. The paper gives an approach to determining a set of methods for deformation monitoring within the territory of mining enterprises engaged in open-pit mining, based on the results of the typification of mining facilities. The developed typification makes it possible to estimate the degree of complexity of mining-engineering facilities, taking into account their size, features of engineering-geological, hydrogeological and orographic conditions, geodynamic processes. To increase the information content of mine surveying, as well as the quality and accuracy of deformation monitoring as a whole, it is proposed to include technologies for Earth remote sensing from space, namely, satellite-based synthetic aperture radar (SAR) interferometry, used within the proposed concept for areal monitoring of deformations and detection potentially hazardous areas at complex and particularly complex opencast mining facilities. The proposed approach to the organization of deformation monitoring was tested within the territory of the Khibiny apatite-nepheline deposit of the Rasvumchorr Plateau: the complexity of conditions for the development of the Tsentralny open pit was evaluated and recommendations were formulated for conducting mine surveying of deformations of the earth’s surface in its territory using satellite-based SAR interferometry. This method was used to analyze deformations of the earth’s surface for the periods from 2007 to 2011 and from 2015 to 2016 according to data from the ALOS PALSAR, TerraSAR-X and Sentinel-1 satellites.

Dust suppression is the most popular method for depositing dust from the air to blast isolation. Improving the isolation system for probable coal dust explosions is an integral part of the problem of dust explosion protection of mining enterprises, the solution of which is one of the most important tasks in the field of occupational safety and health. Purpose: study of physics of the process and the construction of a mathematical model of the movement of aerosols in mine workings in a wide range of changes in the inertial kinematic parameters of the air flow. Research methods. Based on the Boussinesq equation, the Fourier rule and the similarity theorem of complex systems, the analogy of vorticity dispersion and kinematic viscosity, a mathematical model of the movement of dust aerosols under hydro-vortex coagulation conditions is constructed. Some similarity criteria are obtained that ensure the identity of experimental studies and real aerological processes in mines, as well as criterion equations for calculating the coefficient of aerodynamic drag and the time of unsteady inertial motion. Results. Equations are obtained that make it possible to identify aerodynamic processes of aerosol motion under hydro-cyclonic dust suppression through the criteria of Reynolds, Euler and Archimedes, corresponding to the overStokes and Stokes flow regimes. The possibility of reducing the aerodynamic resistance to 20% during hydro-vortex coagulation has been confirmed, which makes it possible to increase the energy efficiency of dust suppression by up to 15% and to increase the turbulization coefficient by at least 20%, thereby reducing the likelihood of a hazardous concentration of dust aerosols. Application. The use of the proposed mathematical model will make it possible to better calculate local aerological processes in mine workings and, as a consequence, to increase the efficiency of turbulization and dust suppression process control at mining enterprises.
