Tradición clásica y exégesis medieval en la literatura de emblemas hispana de temática profana. La iconografía de la Sirena
Authors: Lamarca Ruiz de Eguílaz Rafael
Published: September 2022

La uniformidad de la iconografía de la Sirena en los ejemplos que ilustraron los libros de emblemas hispanos, deriva de la rica tradición clásica y sobre todo medieval que ha llegado hasta nosotros gracias a los múltiples comentarios que su rareza cons­titutiva ha originado. La simbiosis entre animal y ser humano, en este caso la mujer, y los consiguientes significados peyorativos que de continuo la han acompañado, se han constituido desde siempre en un foco de atención para todas las culturas que han par­ticipado de su rica tradición.

Aproximación a la teoría estética del arte del computador (desde una perspectiva española)
Authors: Castaños Alés Enrique
Published: September 2022

El campo de estudio donde más se ha desarrollado la estética de la información, cuyos principales teóricos son el alemán Max Bense y el francés Abraham Moles, es el de la investigación de las formas artísticas generadas con la ayuda de la computadora, una difícil y compleja tarea que se ha centrado en la estética numérica, en la estética semiótica y en la estética generativa. Aspecto capital de la estética cibernética ha sido la primacía concedida al proceso de ela­boración de la obra en menoscabo de la consideración de ésta como realidad física material.
El efecto de trampantojo en la pintura andaluza del Siglo de Oro

Si el concepto tradicional de la pintura es el de figuración en una superficie de dos dimensiones del efecto espacial, acudiendo a las normas de la óptica y de la perspectiva, el trampantojo excede a esta intención, por cuanto busca la confusión del contemplador. Aunque el trampantojo se ha dado en todas las épocas, sin embargo, su uso alcanzar la mayor fama a partir de finales del siglo XVII y principios del XVIII. En España, ser a través de Sevilla, cuando se generalice su uso, sobre todo, hacia 1660. En este texto se realiza un dilatado «excursus» a través de los pin­tores que procuraron engaños a la vista en sus cuadros, durante el Siglo de Oro en Andalucía.

Authors: Aswia Pangsa Rizkina , Lestary Dwi , Masykur Firdaus , Putra Gilang Trio
Published: September 2022

A thorough investigation must be conducted in every aviation incident or accident to find the root cause so that recommendations can be drawn to prevent the same incident or accident from occurring again. This research is a descriptive analysis with quantitative methods. Data were collected from the final reports released by the KNKT from 2015 until 2019. The main causes were grouped using the SHELL Model analysis. The results showed that the most prevalent cause of aviation incidents/accidents in Indonesia was the mismatch between liveware-liveware of which the percentage reached 64%. Furthermore, this mismatch was caused by lack of supervision from management as many as 17 events or 74%; 5 events or 22% were caused by unavailability of rules; and lack of coordination with as many as 1 event or 4%. Within 17 events caused by lack of supervision from management, there were 3 phases of which the events occurred namely the landing phase comprising 59% or 10 events, the cruising phase comprising 18% or 3 events, and the approaching phase consisting of 24% or 4 events. Accidents and serious incidents may occur if latent causes such as lack of supervision from management, unavailability of rules and lack of coordination are not mitigated.

Tube-Based Model Predictive Control with Uncertainty Identification for Autonomous Spacecraft Maneuvers
Authors: Oestreich Charles E. , Linares Richard , Gondhalekar Ravi
Published: September 2022

Autonomous spacecraft must be robust toward uncertainty and disturbances in the system while achieving required levels of performance. As an example, robotic servicing spacecraft must intercept target objects with potentially unknown dynamic properties during active debris removal efforts. This work presents tube-based model predictive control (MPC) with uncertainty identification as a strategy to enhance performance while maintaining robustness in autonomous maneuvers. The proposed algorithm, which is an extension of the standard tube-based MPC framework, measures and predicts the exogenous input to the system (i.e., the uncertainty) online. This in turn enables the robust tube to be shrunk and grown appropriately as the trajectory progresses in both predicted time and actual time. The algorithm is demonstrated in a simulated intercept maneuver with a tumbling target whose inertia tensor is uncertain. Results indicate two improvements over the standard tube-based algorithm: first, better performance is obtained when the initial exogenous input bounds are overconservative, and, second, there is greater flexibility in encouraging robustness when the exogenous input bounds are overly optimistic since the robust tube is updated online. As such, tube-based MPC with uncertainty identification represents an incremental step in enhancing the flexibility of autonomous spacecraft in addressing uncertain scenarios and environments.
High-Resolution Continuous-Scan Beamforming
Authors: Morata David , Papamoschou Dimitri
Published: September 2022

The paper adapts the delay-and-sum beamforming method and related deconvolution techniques for microphone phased arrays comprising fixed and continuously scanning sensors. Processing of the nonstationary signals introduced by the scanning sensors requires division of all the signals into quasi-stationary blocks and application of a frequency-dependent window within each block. Three distinct approaches are developed: application of delay and sum to each block of the divided signals, followed by assembly of the outputs of the blocks; a cross-spectral matrix completion process; and a partial fields decomposition method. The last two approaches result in a unified cross-spectral matrix that facilitates deconvolution of the array output. The methodologies are applied to a synthetic noise source and to a supersonic underexpanded jet that presented the phenomenon of screech. Introduction of a single scanning sensor to a far-field array comprising 13 fixed sensors significantly improves the fidelity of beamforming. The deconvolved images of the jet noise source resolve fine shock-cell features for which the dimensions are similar to those imaged by optical techniques in past investigations.
Radiative Coefficients and Their Influence on In-Depth Heating of Porous Ablators
Authors: Banerjee Ayan , Yassin Ahmed H. , Davuluri Raghava S. C. , Martin Alexandre , Poovathingal Savio J.
Published: September 2022

High entry speeds and exotic planetary gases can result in significant radiative heat loads on space capsules. The mechanism behind the transport of radiative signatures is fundamentally different from the conductive mode of energy transport, and penetration of radiative signatures depends on the radiative coefficients of the thermal protection system (TPS) material that protects the space capsule. The radiative coefficients of carbon-based and silica-based fibrous materials have been computed as functions of wavelength using the photon path length Monte Carlo method by explicitly accounting for the microstructure of the material. Significant variations in the radiative coefficients are observed at wavelengths that are relevant to shock-layer emissions. Although carbon-based fibrous materials exhibit higher absorption coefficients in comparison to silica-based systems, the absorption coefficients of carbon-based material drop by two orders of magnitude in the range of 100–200 nm. The radiative coefficients of carbon-based fibrous material are seen to be dominated by scattering and absorption with minimal transmission. However, the transmission coefficients for the silica system dominated the radiative coefficients in the range of 100–1000 nm, which corresponds to most shock-layer emissions. The radiative coefficients are used to solve the radiative transfer equation using the P-1 approximation to obtain the in-depth radiative heat flux. The total energy equation for decomposing porous TPS materials is solved with the radiative heat flux from the P-1 approximation and the conductive heat flux using the Fourier law. It is observed that peak temperatures inside the material are higher when radiative transport is explicitly accounted for through the P-1 approximation. Small variations in the absorption coefficient of the silica-based materials also affected the in-depth temperature profiles. Additionally, a broader temperature distribution is obtained inside the material with a low absorption coefficient, and the charring density profiles are influenced by the radiative heat flux. This study demonstrates that it is important to include radiative transport in material response solvers, and radiative coefficients must be accurately computed by accounting for the microstructure of the material.
Global Reliability Sensitivity of the Structure Under Fuzzy Uncertainty and Its Estimations
Authors: Chen Zhuangbo , Lu Zhenzhou
Published: September 2022

Global reliability sensitivity (GRS) index under fuzzy uncertainty is defined as the mean of the absolute difference between unconditional failure credibility and conditional failure credibility, which is important to quantify the effect of fuzzy inputs on failure credibility of the structure. The solution of this index requires nested analysis of conditional failure credibility and fuzzy mean, which introduces a large amount of computation. To efficiently estimate the GRS under fuzzy uncertainty, a method combining fuzzy simulation (FS) with fuzzy first-order and second moment (FS–FFOSM) method as well as a fuzzy sequential optimization and reliability assessment (FSORA) method are proposed. Compared with the direct double-loop FS method, in which both the conditional failure credibility and the fuzzy mean are estimated by FS, the proposed FS–FFOSM uses a more efficient FFOSM method to estimate the conditional failure credibility in the inner loop, which improves the computational efficiency of estimating GRS under fuzzy uncertainty. To further improve the computational efficiency, this paper also transforms the estimation of GRS into the solution of the optimization model under the constraint of failure credibility and establishes the FSORA method to solve the optimization model. The FSORA method uses a series of cycles of deterministic optimization and inverse design point analysis corresponding to the required fuzzy reliability index by GRS to reduce the iterations, and then the computational efficiency is further improved. Several examples illustrate the computational efficiency and accuracy of the proposed methods.
Sector Mode Assembling Reduction Technique for High-Fidelity Blisk Models with Geometry Mistuning
Authors: Zhou Biao , Zhao Jingchao , Ye Nan , Berruti Teresa M.
Published: September 2022

Blade mistuning in blisks arises primarily from the scatters of blade geometry profiles caused by manufacturing tolerance, in-service wear, blade repairs, etc. There is a recent trend to capture the blade-to-blade geometry variances through precise geometry measurements by a 3D optical scanning system in order to obtain an improved blade geometric mistuning evaluation capability. However, this usually leads to prohibitive computational costs due to the large-scale, high-fidelity industrial blisk finite element models. This paper develops an original model reduction approach, Sector Mode Assembling Reduction Technique (SMART), specifically for the high-fidelity blisk model fully mistuned by blade geometric variances, with either topologically compatible or incompatible blade meshes. The basic idea of SMART is to construct the sector-level reduction mode basis by strategically assembling the truncated cyclic modes independently computed for each “isolated” sector with assumed cyclic symmetry at the sector interfaces. Benefiting from the block structure of the SMART mode basis, the reduced-order models are derived by a series of sector-level projections with a relatively low memory requirement and computational cost. Another hidden benefit is that the SMART approach enables efficient structural modification predictions of the global blisk modes because only the modes of the sectors undergoing blade modification need to be re-evaluated and replaced in the SMART mode basis. The SMART approach is applied into a high-fidelity “as-measured model” of a blended blisk, constructed upon the geometry measurement by the state-of-the-art 3D optical scanning technology. It is fully demonstrated that the reduced-order model derived by SMART, featured by a minimal size, is able to reproduce the dynamics of the full-order as-measured blisk model with high accuracy.

Published: September 2022

A 38-year-old female patient complained of lip augmentation. With a preliminary diagnosis of RossolimoMelkerssonRosenthal syndrome (monosymptomatic form), chronic fissure of the lower lip, the patient was sent for examination in order to exclude tumor pathology and vascular malformation. According to the results of a comprehensive clinical and laboratory examination, it was found that lip enlargement is due to the formation of granulomas. Additional follow-up by a pulmonologist confirmed the presence of sarcoidosis of the lungs with involvement of the mediastinal lymph nodes. A comprehensive examination made it possible to verify the diagnosis of multisystem sarcoidosis in a patient with macrocheilitis. As a result of complex therapy using surgical methods and systemic glucocorticosteroids, a rapid dynamics of clinical symptoms was observed and remission was achieved. This clinical case demonstrates a combination of sarcoid lesions of the tissues of the mediastinal lymph nodes, lung parenchyma and lips. It was the presence of macrocheilitis that was the main reason for visiting a dermatovenereologist and was the reason for choosing the subsequent tactics of examination and treatment. As a result of complex therapy using surgical methods of treatment and systemic glucocorticosteroids, carried out entirely within the framework of the program of state guarantees of free medical care for citizens, a stable remission of the disease was achieved.
Splenic abscess presenting as diabetic ketoacidosis: A rare cause of DKA in Type 2 DM patient
Authors: Pradeep Anantha Krishnan , Mishra Mayank Kumar , Raina Rohit , Pathania Monika , Kant Ravi
Published: September 2022

Diabetic ketoacidosis is a relatively common and potentially life-threatening complication of insulin deficiency. The prevalence of DKA is relatively common in patients with Type 1 diabetes mellitus in comparison with Type 2 diabetes mellitus. The prevalence of DKA is seen in 0–128 cases per thousand population in Type 1 diabetes mellitus while Type 2 DM has a prevalence of 18% of the total population. Abdominal pain is the most common and specific symptom of DKA which is reported at around 46%. The two most common infections precipitating DKA are community-acquired pneumonia and UTI which correspond to around 30–50% of the total burden. Meanwhile, any infection or sepsis can precipitate DKA, the splenic abscess is rare, and there have been reported only a few cases. In patients with poor glycemic control, absence of urinary tract infection, and community-acquired pneumonia, deep organ abscesses should be screened for. Here, we present a case report of patient with non-resolving DKA who presented with splenic abscess.
Temperature Dependence of the Relative Rates of Chlorination and Hydrolysis of N2O5 in NaCl-Water Solutions.

Published: September 2022

We have measured the temperature dependence of the ClNO2 product yield in competition with hydrolysis following N2O5 uptake to aqueous NaCl solutions. For NaCl-D2O solutions spanning 0.0054 to 0.21 M, the ClNO2 product yield decreases on average by only 5% from 5 to 25 ˚C. Less reproducible measurements at 0.54 and 2.4 M NaCl also fall within this range. The ratio of the rate constants for chlorination and hydrolysis of N2O5 in D2O is determined to be 1147 ± 65 at 25 °C, favoring chlorination. An Arrhenius analysis reveals that the activation energy for hydrolysis is just 3.0 ± 1.8 kJ/mol larger than for chlorination. In combination with the measured pre-exponential ratio favoring chlorination of 419 (-215) (+542), we conclude that the strong preference of N2O5 to undergo chlorination over hydrolysis is driven by dynamic and entropic, rather than enthalpic, factors. Molecular dynamics simulations elucidate the distinct solvation between strongly hydrated Cl- and the hydrophobically solvated N2O5. Combining this molecular picture with the Arrhenius analysis implicates the role of water in mediating interactions between such distinctly solvated species and suggests a role for diffusion limitations on the chlorination reaction.

Published: September 2022

Electrodeposited dendritic copper foams have been extensively studied as an electrocatalyst for CO2 reduction reaction (CO2RR). Many parameters, such as dendrite size, porosity, pore size, and crystal faceting, define the hierarchical properties of these structures and their subsequent bubble evolution and CO2RR capabilities. Here we studied the effects the electrodeposition conditions (potential, pH) have on the resulting crystallinity, microstructure, and macroporosity of the copper foam. We characterized these morphological differences and the corresponding effects on electrocatalytic activity. We showed that the composition of the electrodeposition bath can have significant effects on the mechanics of bubble formation and detachment at the surface during hydrogen evolution reaction (HER) in acidic solutions. Similarly, the electrodeposition conditions for the synthesis of the foam affected the product selectivity during CO2RR electrocatalysis. Foams deposited in alkaline electrodeposition solutions showed high faradaic efficiency and specificity towards C2H6, an uncommon product of CO2RR, at modest applied potentials (-0.8 V vs. RHE).

Authors: Magauer Thomas , Paciorek Jan , Sokol Kevin , Hoefler Denis , Wurst Klaus
Published: September 2022

Here, we report a general synthetic entry to dihydrooxepine-spiroisoxazoline (DOSI) natural products that culminated in the first total synthesis of psammaplysin A. For the synthesis of the unique spirocyclic fragment we employed a strategy that features two key transformations: (1) The use of a diastereoselective Henry reaction/cyclization sequence granted access to the C7 hydroxylated isoxazoline scaffold in one step. (2) A regioselective Baeyer–Villiger ring expansion enabled selective installation of the fully substituted dihydrooxepine and avoided the risk of a previously observed oxepine-arene oxide rearrangement. The overall synthesis proceeds in 13 steps from inexpensive starting material.
Internecine War and Intra-Nicene Sin
Authors: Goodin David K.
Published: September 2022

The Russo-Ukrainian War, beginning with the invasion and illegal annexation of Crimea in 2014, witnessed a full-scale invasion of the entire nation in early 2022. As the renewed conflict enters into its seventh month, its repercussions threaten to impact other nations in myriad ways, ranging from radioactive catastrophes from attacks on civilian nuclear power plants to direct military aggression or spillover to other nations. One of these looming concerns is a famine in Ethiopia resulting from reduced access to Ukrainian wheat; the Black Sea shipping lanes are under threat by Russian warships and mines. This article offers a theological reflection on this conflict, and how famine is now being used as a weapon of war. The orations of Basil the Great are discussed in relation to economic analyses on the causes of famine by Nobel Laureate Amartya Sen. These are brought forward in relation to the Russo-Ukrainian War, which has become an internecine war within Orthodox Christianity.
Rule Ordering in Uvwie
Authors:   National Institute for Nigerian Languages, Nigeria, P.O. Ekiugbo
Published: September 2022

One of the assumptions underlying theories of phonological derivation is that the phonological architecture of any language consists of, at least, an abstract underlying form, its surface form and conditions which derive the surface form from its underlying form. It is further assumed that the conditions are serially ordered in frameworks which subscribe to the rule ordering such as orthodox generative phonology and lexical phonology. In the present study, these issues are engaged in the case of Uvwie. In particular, the study seeks to investigate the conditions (processes and rules) which derive surface forms from their corresponding underlying forms, and the order in which they apply. Thus the study will examine the different well-motivated phonological rules attested in the derivation of Uvwie formatives, and provide evidence for the order in which the processes apply. The study employe data documented in Ekiugbo (2016), and couched its analysis within rule ordering principle of generative phonology. The study identifies six rules, which are ordered thus: nasal assimilation > glide formation > vowel elision > tone fusion > vowel lengthening > consonant elision.
Valency Increasing in South Ethio-Semitic
Authors:   Addis Ababa University, Ethiopia, T.Y. Zeleke
Published: September 2022

The present paper focuses on a descriptive method of valency-increasing devices in five South Ethio-Semitic languages (Amharic, Harari, Kɨstane, Məsqan, and Endəgaɲ). The five languages were selected for two reasons. The first reason is that conducting a valency study on all South Ethio-Semitic languages would have been impossible. With limited resources and time, it will prove difficult to cover all languages. The second reason is that, except for Amharic, these languages are known for being the least studied. Most of them even lack sufficient recording and description. So this research needs to choose the representative language in each branch. As a result, no explicit theoretical framework is followed; data analysis is guided solely by a descriptive perspective. The study’s data was gathered by consulting native speakers via elicitation. Valency has been considered as both a semantic and syntactic notion. As a semantic notion, it is used to refer to the participants in an event; as a syntactic notion, it is used to indicate the number of arguments in a construction. There are different types of transitivity classes of verbs in the South Ethio-Semitic Language, which is spoken in Ethiopia: intransitive, transitive, and ditransitive. Apart from these, there are verbs that can be used both intransitively and transitively. The facts that provide clear evidence for grammatical relations in South Ethio-Semitic languages are crucial to the study of the concept of valency-increasing devices. As is the case in many languages, South Ethio-Semitic languages possess morphosyntactic means through which the valency of verbs can be adjusted. The application of these morphosyntactic processes decreases or increases the valency of verbs. This article looks at valency-increasing devices in Causative and Applicative South Ethio-Semitic languages.

Published: September 2022

Background: There have been system inefficiencies in the profiling and management of female breast cancer in Alexandria, Egypt. Aims: To identify barriers to full implementation of international guidelines for the management of female breast cancer patients. Methods: Female breast cancer data were extracted from records of 3 public oncology services in Alexandria, Egypt, from 2007 to 2016 and analysed. Results: A total of 5236 of the available 7125 records were usable. Median age of the patients was 54 years, and the median duration of pre-diagnosis complaint was 3.1 months. Some 522 (31.5%) of the patients had a family history of cancer. For tumour stage, 2527 (55.2%) were early, 1717 (37.6%) were locally advanced, and 331 (7.2%) were at stage IV. Estrogen receptor, progesterone receptor, and HER2 were positive in 3869 (85%), 3545 (78%), and 461 (15.3%) patients, respectively. Chemotherapy started after a median 1.03 months. Adjuvant chemotherapy was given to 3667 (91.7 %) patients and neoadjuvant chemotherapy to 333 (8.3%); 3686 (92.1%) received anthracycline-based combination chemotherapy, and 3613 (86%) received hormonal treatment. One hundred and eighty of 317 eligible patients received Trastuzumab. Local and/or distant recurrence was seen in 1109 (21.2%) patients. In nonmetastatic cases, median overall and disease-free survival were 149.1 and 77.1 months, respectively. In metastatic cases, median progression-free survival was 19.6 months. Conclusion: We observed defects in the record system, there was delay in diagnosis and treatment, and nonadherence to targeted therapy in many patients. Strengthening of national and hospital-based registries is needed in Alexandria, Egypt, with a robust patient navigation system and targeted information, education and communication strategies. Continuous outcomes monitoring and adaptation to implementation needs should be sustained.
Assessment of the stress state of round and annular cross-section beams made with different tensile and compressive properties materials
Authors: Kashelkin V. V. , Demidov A. S. , Kapustin E. A.
Published: September 2022

At present, there is great interest in carbon-based materials. They have high thermomechanical properties and mass characteristics, are quite technologically advanced. Such materials are widely used in aviation and space technology, for example, for the manufacture of load-bearing elements, beams, frames, as well as aircraft and rocket skin elements. The article considers the stress state of bent beams of circular and annular section made of carbon fiber reinforced plastics. When tested in tension and compression, such materials, called multi-modulus, exhibit different properties. Therefore, for strength calculations, it is necessary to use special strength models. A method is proposed for calculating the bending of beams of circular and annular cross-section made of M46 and IMS-65 carbon fiber reinforced plastics. Their tensile and compressive moduli and corresponding strengths were determined by testing on a ZDM-10 machine with an accuracy of ±1,25%. The examples show that in the calculations it is necessary to take into account the difference in tensile and compression properties, as well as the real position of the neutral axis of the bent beam section.

Tribo-Device to Quantify of Friction in Rake Face Using Line Contact Mechanism Under Different Machining Conditions. (c2021)
Authors:   ,   Lebanese American University, Al Fleety Al Hussein
Published: September 2022

In typical body contact, the friction force is proportional to the load between the two surfaces. However, in cutting conditions, it is more complicated due to the presence of sliding and shearing actions on the interface. The purpose of this research is to introduce and evaluate a new Tribo-Device aims to isolate the aggressive contact on the rake face in order to better understand the high-pressure contact effect on it. The device that is based on line-contact mechanism mimics the normal force applied on the rake face to associate a pressure field results in friction forces, which represents accurately the contact zone. The design validation process depends on a comparison of forces between the experiments, conventional cutting simulation and another finite element model that simulates the functionality of the introduced device. The friction factor used in the simulations is calculated using the experimental analysis. The stress maps generated at the contact of the two FEM models are also compared. The results show that the new device has high potentials in simulating high contact pressure on the rake face. The research will give an enhanced understanding of the tribological properties at the tool-chip interface under high contact pressure. The introduced device is also used to evaluate the effect of sliding speed, normal load, cryogenic coolant and solid lubricants on the tribological properties occurred at the interface. The results show that sliding speed and normal load have a notable influence on friction factor, wear mechanisms and tool life. In addition, it was shown that solid lubricants are mainly useful in reducing friction forces generated at the interface, therefore, improve tool life by protecting it from the aggressive mechanical load. On the other hance, cryogenic gases can be considered as a coolant and lubricant. However, its best performance is at high temperature zones. The results of this research can be used to make corrective actions on cutting simulation, test cutting tool coatings under aggressive wear condition and evaluate new types of metal cutting lubricants.

Abstract. The study and analysis of natural objects makes it possible to form an ecological idea of the research area and identify some patterns of the organization of plant communities, filling in information about certain plant species with their specific features of growth and distribution. This study is devoted to the study and analysis of the flora of the village of Pribelsky, Karmaskalinsky district, located in the center of the Republic of Bashkortostan on the left bank of the Belaya River. 225 plant species from 180 genera and 66 families were discovered and analyzed by the route method of research. During the analysis, generally accepted methods for determining the material were used. As a result of a detailed acquaintance, it was revealed that the predominant family in the flora of the studied territory is the Asteraceae family, which includes 39 plant species (17.3 %). Ecological analysis conducted to identify the quantitative composition of plants by such factors as moisture, light and soil nutrition showed that mesophytes (70.2 %) are most represented in the flora of the first category, light–loving plants (87.1 %) from the second and mesotrophs (72 %) from the last. The distribution of species into ecological groups was caused by their unequal adaptability to the above environmental factors. The biological and morphological analysis of plant life forms carried out according to the Raunkier system showed that hemicryptophytes are most represented in the flora (55.5 %). The presented results are quantitative and qualitative indicators of resources in the system of monitoring the state of the environment and environmental protection activities, which in turn is the basis for comparing the analyzed plants with plants of other territories by their key characteristics.

Abstract. The study shows the values of heart rate variability in patients with paroxysmal atrial fibrillation treated with allapinin monotherapy and a combination of allapinin with metoprolol, allapinin with sotahexal and allapinin with diltiazem with preventive antiarrhythmic therapy. Analysis of heart rate variability allows you to determine the state of the autonomic nervous system. A high probability of an unfavorable outcome of diseases of the cardiovascular system is observed with the predominance of the tone of the sympathetic nervous system and a decrease in the tone of the parasympathetic nervous system. A decrease in heart rate variability and a predominance of sympathetic nervous system tone are predictors of the occurrence of another paroxysm in patients with paroxysmal atrial fibrillation. Indicators of heart rate variability are of great importance in the selection of antiarrhythmic therapy. The initial predominance of the tone of the parasympathetic nervous system in comparison with healthy ones and the absence of negative dynamics after 1 year was recorded in patients with paroxysmal atrial fibrillation with allapinin monotherapy. Patients treated with a combination of allapinin and metoprolol had a predominance of the tone of the parasympathetic nervous system initially compared with the healthy group and a transition to sympathicotonia after 1 year compared with healthy, control and their own baseline values. Patients receiving allapinin and sotahexal had no significant differences either at the beginning of the study or after 1 year. Predominance of sympathetic nervous system tone was registered in patients treated with allapinin and diltiazem by the end of 1 year of the study in comparison with a group of healthy.

Abstract. Relevance: Squat cloudberry (Rubus chamaemorus) has a sufficiently wide range of therapeutic effects for various diseases. At the same time, it does not refer to pharmacopoeia medicinal plants, but is used as folk medicine. Tannins (plant tannins) detected in Rubus chamaemorus hold a special place among the other biologically active substances of this plant. They have anti-inflammatory, antimicrobial, antioxidant and anti-cancer activity. Also, their properties are applicable in the prevention of cardiovascular and metabolic diseases. The aim of the study is to establish the presence of tannins and their quantitative determination in the leafs of Cloudberry squat, growing in the Vologda region for the possible determination of the raw materials of this plant as medicinal. Materials and methods: the presence and quantitative content of tannins in the raw materials of the squat cloudberry (leaves) growing on the territory of the Vologda region was determined using various methods of chemical analysis. Results of the study: qualitative samples confirmed the presence of tannins in the leaves of the studied plant (gelatin sample), as well as the sufficient presence of their hydrolyzable forms (iron-ammonium alum sample); quantitative (by permanganatometry) determined the content of tannins relative to the total dry weight of raw materials, it was 15.03 ± 1.14% (95% confidence interval = 14.12-15.95). The results obtained are consistent with the data of other researchers, the average relative proportion of tannins in relation to the total mass of the dry plant correlates to the average scientific results. The conclusion is made about the possibility of attributing Rubus chamaemorus, which grows in the Vologda region, to medicinal plants potentially recommended for use in the pharmaceutical industry.

Abstract. The article presents the results of the analysis of the production and economic activities of Russian and foreign pharmaceutical companies in order to study modern approaches to risk management within the quality management system. Pharmaceutical enterprises are now actively implementing a quality management system, as this allows you to ensure and control quality at the required level throughout the entire life cycle of a medicinal product. Risk management in the pharmaceutical industry is an important component of the pharmaceutical quality system. Analysis of the position of risk management in the pharmaceutical industry in order to form the basis for the development of guidelines for effective risk management is an important area of research. The purpose of this article was to develop competent organizational solutions for the effective operation of a pharmaceutical enterprise related to the improvement of the quality management system through the implementation of effective risk management. The annual reports of pharmaceutical manufacturers of medicines for medical and veterinary use, pharmaceutical substances and substances used in pharmaceutical production were selected as research materials. The methods of information analysis, induction and synthesis were used as research methods. As a result of the work, a diverse approach of pharmaceutical enterprises to the categorization of risks, an uneven distribution of attention to different categories of risks, their underestimation and the need to develop a risk management manual were established, and measures were proposed to introduce this manual into the activities of pharmaceutical enterprises, including conferences and training courses to improve the competence of organizations in the processes of risk management and the involvement of government agencies in the implementation of risk management.

Abstract. Currently, the low efficiency of treatment of women with infertility with a low ovarian reserve (decrease in the number and quality of eggs) remains an urgent problem in practical healthcare. Every fifth married couple faces the problem of infertility, while the number of cycles of assisted reproductive technologies, both in our country and abroad, increases annually. A decrease in the ovarian reserve naturally occurs in women after 35 years, but this is not only a problem of late reproductive age, in young women it occurs after inflammatory diseases of the ovaries; transferred operations on the ovaries for cysts, endometriosis; intoxications of various etiologies. The study is devoted to the development and evaluation of the effectiveness of the program of medical and organizational measures for women with infertility and low ovarian reserve, when using assisted reproductive technologies. The following methods were used: analytical, sociological, statistical, organizational experiment. The object of the study is the organization of medical care for women with infertility who have a low ovarian reserve. The subject of the study is the indicators of gynecological morbidity, medical activity of women with infertility and low ovarian reserve; the effectiveness of the use of specialized medical care using assisted reproductive technologies for this group of patients. The main group included 150 women (age 37,3 + 0,23 years), 120 women - the comparison group (age 37,4 + 0,35 years). Results: a program of medical and organizational measures was developed for women suffering from infertility and having a low ovarian reserve, which can significantly increase the effectiveness of infertility treatment by 2.6 times, recommended for implementation.
