Authors: Hayes Sandra C. , Newton Robert U. , Spence Rosalind R. , Galvão Daniel A.
Published: October 2023

Desde la primera publicación de la declaración de consenso sobre pautas de ejercicio para personas con cáncer, de la asociación Ejercicio y Ciencias del Deporte - Australia (ESSA, Exercise and Sports Science Australia), ha ocurrido un crecimiento exponencial en las investigaciones que evalúan el papel del ejercicio antes, durante y después del tratamiento del cáncer. El propósito de este reporte es utilizar la evidencia científica actual, junto a la experiencia clínica y los principios de las ciencias del ejercicio, para poner al día la declaración de consenso de ESSA sobre la prescripción de ejercicio específica para el cáncer. En esta declaración de consenso se reporta un resumen de los beneficios alcanzados mediante el ejercicio luego de un diagnóstico de cáncer, así como las fortalezas y limitaciones de la evidencia acumulada. Se propone, entonces, un marco de prescripción del ejercicio para permitir la aplicación de consideraciones específicas para el cáncer en la individualización, especificidad, seguridad, factibilidad y progresión del ejercicio para toda clase de pacientes. Se ofrecen consideraciones adicionales específicas para la prescripción del ejercicio cuando hay presencia de enfermedades hematológicas, osteomusculares, sistémicas, cardiovasculares, linfáticas, gastrointestinales, genitourinarias y neurológicas y preocupaciones relacionadas con su tratamiento, así como la presencia crónica de comorbilidades. Además, se identifican y comentan temas prácticos específicos y barreras que deben tomarse en cuenta para la prescripción del ejercicio. Si bien es cierto que el ejercicio multimodal de intensidad moderada a intensa será apropiado para la mayoría, no hay una prescripción establecida ni una dosificación semanal, que se puedan considerar basadas en la evidencia, para todos los pacientes de cáncer. Es necesaria una prescripción del ejercicio dirigida específicamente a esta población, que asegure el mayor beneficio (conforme lo defina cada paciente) a corto y largo plazo, con un bajo riesgo de perjuicio.

Although data on the decrease in ovarian function after hysterectomy (GE) are found in literature sources, the nature of changes in the hormonal and metabolic profile, its chronological sequence, the issue of the relationship with the development of metabolic syndrome (MS), even in the case of preservation of ovarian tissue, remain controversial and fragmented, which served as an impetus for conducting this study. Purpose - to assess the risk of metabolic disorders after GE during the menopausal transition. Materials and methods. A comprehensive assessment of the long-term consequences of GE was carried out in 160 women of the menopausal transition age. Metabolic homeostasis parameters were evaluated before surgery and in dynamics after surgical intervention (after 12 months). Risk factors were identified during a general clinical examination, based on anamnestic data. Indicators of carbohydrate and lipid metabolism were evaluated in the examined women. Inclusion criteria: the age of the menopausal transition, GE due to benign uterine pathology, the patient's consent to participate in the research. Results. Analysis of carbohydrate metabolism indicators showed an increase in the HOMA-IR index and postprandial glucose level, changes in the lipid profile. When comparing clinical symptoms and laboratory research methods, in 34.37% of cases, the formation of MS was noted one year after GE. Based on multivariate analysis using binary logistic regression, the following risk factors for metabolic disorders were found to be statistically significant: high body mass index, waist circumference above 80 cm, age older than 45, climacteric syndrome, GE. Conclusions. A high body mass index, a waist circumference greater than 80 cm, the presence of signs of the climacteric syndrome, GE and age older than 45 years show the association with the development of metabolic disorders in the distant postoperative period, and their combined effect increases the risk of their development. These factors at the preoperative stage can serve as prognostic markers of metabolic disorders in the distant postoperative period. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

The immaturity of the organs and systems of preterm born children significantly complicates the differentiation between physiological and pathological changes in the brain. The etiology of brain damage in premature babies is complex and multifactorial, and even with the most favorable course of the neonatal period, they require additional respiratory support, a large number of invasive medical interventions and have a high risk of infectious complications. Sepsis-associated encephalopathy (SAE) is defined as diffuse or multifocal cerebral damage that is caused by a systemic response to infection even without clinical or laboratory evidence of direct brain infection. Purpose - to determine the clinical features of sepsis-associated brain damage in prematurely born children <32 weeks gestation with a birth weight <1500 g. Materials and methods. 38 prematurely born children, who were divided into two groups, were examined. The Group I (n=14) included children who were diagnosed with sepsis in the early neonatal period. The Group II (n=24) included prematurely born, in which no septic lesions were observed. Results. Children of both groups were born in a state of severe and moderate asphyxia. Analysis of associations between maternal, obstetric, and antenatal factors showed a significant prevalence of such factors as prelabor rupture of membranes, сervical weakness, rupture of the fetal bladder, and placement of an obstetric pessary in children with sepsis. All children with sepsis had pneumonia, acute kidney injury, and brain injury in the neonatal period. In the neurological status of children with very low birth weight who underwent SAE, the seizure syndrome, 3-4 grade intraventricular hemorrhages, periventricular leukomalacia, complications in the form of post-hemorrhagic ventriculomegaly were significantly more common. Conclusions. In children with very low birth weight who underwent SAE, convulsive syndrome, 3-4 grade intraventricular hemorrhages, and periventricular leukomalacia were significantly more common. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Tourniquet syndrome is a complex of pathological changes that occur in response to strangulation circular compression of part/parts of the body or organ, characterized by neurovascular disorders that can lead to the development of necrosis and gangrene. Strangulation of soft tissues can occur with various fibrous materials - wool, cotton, various cords, jewelry, Christmas tree decorations. In children, the most common cause of strangulation is hair and threads, in adults - jewelry. Purpose - to draw the attention of the medical community to a rare pathology, the tourniquet syndrome in children, which, despite its rather characteristic picture, is not always immediately recognized, which can lead to serious consequences. The leading etiological factor in the development of tourniquet syndrome can be postpartum telogen outflow in mothers, which is manifested by a large amount of hair prone to loss. The authors recognize the toes as the most frequent localization of the strangulation hair bundle in tourniquet syndrome, the II and III toes of the feet and hands are more often caught in the loop. Also, it is not uncommon for several fingers to be entwined. With tourniquet syndrome, a complication in the form of necrosis of the fingers, which requires their amputation, is about 7% of all cases of finger and foot pathology. Quick recognition and removal of the tourniquet for genitaltourniquet syndromeprevents devascularization of the clitoris and penis and their possible self-amputation. Conclusions. Hair bundle syndrome, or tourniquet syndrome, most often occurs in young children and can have serious consequences. To prevent this phenomenon, children’s clothes should be checked for the presence of threads and loops on the inside, the presence of piles of hair and threads in the “blind” parts of the clothes, turn the clothes inside out before washing, which helps prevent the accumulation of future bundles. It is also recommended that mother and child sleep separately. In case of injuries of the upper limbs, it is recommended to know jewelry from the fingers. Alertness about tourniquet syndrome will help avoid serious complications in children. It should also be remembered about the intentional cruel treatment of children with the imposition of potential bounties. No conflict of interests was declared by the authors.
Using conversation analysis to identify unresponsiveness in peer interactions in inclusive groups
Authors: Kilpiä Anni , Dindar Katja , Kärnä Eija , Räty Hannu , Kämäräinen Anniina , Suero Montero Calkin
Published: October 2023

Background: Previous research regarding unresponsiveness in peer interaction, including participants on the autism spectrum (AS), is mainly based on predefined categorizations of unresponsiveness; thus, there is a need for conversation analytic research to examine unresponsiveness from participants’ perspectives. Method: Multimodal conversation analysis (CA) was applied to examine unresponsiveness in task-focused multiparty peer interactions of an inclusive group, including one participant on the AS. Results: The results showed that it was not meaningful to analyze unresponsiveness in situations where there was no (aligning) response and all participants’ orientations revealed that a response was (not) needed. Instead, participants’ discrepant orientations to the response relevance made unresponsiveness a meaningful issue for participants to negotiate. Discussion/conclusion: The CA approach can be useful for examining unresponsiveness accurately. The combination of both the speaker and recipient(s) orientations to response relevance can be used as a conceptual tool to identify unresponsiveness when it is relevant for the participants.

Published: October 2023

Background: Asking patients who have been referred to memory clinics open questions about recent events has been shown to have diagnostic relevance. Method: We use conversation analysis to look at responses to questions about recent events. The interviewees are healthy control (HC) participants, people with mild cognitive impairment (MCI), and people with Alzheimer's disease (AD). Results: We show differences among the groups’ use of claims of memory problems, self-directed questions, and well-prefacing. Healthy control participants produce more talk in response to all of these, while people with MCI and AD either do not, or do so in demonstrably different ways from both HC participants and each other. Discussion/conclusion: Healthy control participants are both willing and able to ‘show off’ their memory, while people with AD are willing but generally unable to do so. People with MCI, in contrast, display themselves as both unwilling and unable to engage with the agent's questions as tests of memory.
Odpusty jako realna pomoc w przemianie życia
Authors: Kulik Bogdan
Published: October 2023

Nauka o odpustach należy do oficjalnego nauczania Kościoła. Konstytucja apostolska Indulgentiarum doctrina św. Pawła VI z 1967 roku pozostaje do dzisiaj impulsem do dalszej refleksji nad historią, teologią, praktyką odpustów, a także nad ich znaczeniem dla życia człowieka. Jednak do tej pory nie zostało bezpośrednio podjęte zagadnienie, jaki wpływ ma praktyka odpustów na konsekwencje przeszłości, teraźniejszość i przyszłość osób starających się odpusty zyskiwać. W związku z tym celem artykułu jest próba ukazania, w jaki sposób proszenie o odpusty może realnie przemieniać konsekwencje naszego „wczoraj” oraz nasze „dziś” i „jutro”. Refleksja będzie dotyczyła przede wszystkim definicji odpustu i warunków koniecznych do jego otrzymania. Studium zostanie zwieńczone wnioskami oraz propozycjami dalszego namysłu nad tym, jaki zachodzi związek między odpustami i życiem człowieka.

The article is devoted to the consideration of general approaches to automating the analysis of aqueous media, which are the main objects of chemical analysis including natural and waste waters, as well as technological media in various industries (microelectronics, biochemical industries, nuclear and thermal power engineering), which are the main consumers of high-purity water used for pre-start flushing of inline equipment to the required cleanliness of surfaces, for preparation of coolants that ensure the operation of nuclear and thermal power plants. In all these cases, the content of impurities in used or spent and intended for discharge aqueous media is strictly regulated. Changes in the content of impurities in controlled media often occur spontaneously due to equipment failure on the controlled objects. Prompt response to such changes and their timely elimination can be performed more efficiently if chemical and technological control of the normalized parameters of aqueous media of any named origin and destination is carried out in a continuous automatic, on-line, mode, which guarantees the exclusion of gaps or delays in obtaining information about equipment failure on a controlled facility in case of technological control or about unauthorized discharges of pollutants in case of environmental control. Possible methodological approaches to the development of systems for continuous chemical monitoring of quality or levels of contamination of aqueous media are considered on the basis of the above prerequisites, and applicability of various flow methods for these purposes is discussed in the order of their appearance in the arsenal of analytical chemists.

The article is of a review nature, in which the dynamics of publication activity is analyzed and the possibilities of using quantum dots to solve various analytical problems are evaluated. The attention is paid to both traditional and relatively rare areas of analytical application of these nanostructures. A brief review of the types, advantages and disadvantages of synthesis methods, the influence of external factors on the band gap and luminescence intensity of inorganic nanosized phosphors, quantum dots of different nature, is presented. The areas of application and the main tasks solved with the use of quantum dots are systematized. Their analytical characteristics, operational properties and ways of regulating them are discussed. An effective way to control the analytical properties of the systems based on quantum dots is a directional change of the affinity for components by varying the nature of the stabilizing or modifying shell. Semiconductor colloidal quantum dots coated with a larger bandgap shell were selected for analytical use as the most commonly used systems due to their good photostability and fluorescence quantum yield. The advantages and disadvantages of other types of shells, as well as ways of modifying them, are shown. Solutions for organic analysis and medical diagnostics are considered. Systems of quantum dots used as biosensors with various guiding agents are considered, and their properties, advantages and disadvantages compared. Little studied issues and solutions in the direction of using quantum dots for developing sensor systems and their use for non-invasive analysis of living systems based on the results of detection of volatile organic compounds are identified.
Application of interval estimations of the total content of antioxidants for the analysis of juice products by the CUPRAC method using the Cu(II) – NC–PMM system

Сu(II) – neocuproinе indicator system (CUPRAC method, R. Apak) was used for spectrophotometric determination of the total content of antioxidant reductants (ΣAO) in juice products. Gallic acid, ascorbic acid, quercetin, luteolin, dihydroquercetin, which are typical for fruit and berry juices, as well as trolox, as a frequently used standard, were used as model compounds of antioxidant-reducing agents (AO). The polymethacrylate matrix (PMM) with immobilized reagents was immersed in the test solution for 20 minutes, and then photometrically measured at 450 nm. The aim of the work was to compare two methods for estimating ΣAO: a) in terms of the content of a standard substance (generally accepted method); b) in the form of an interval calculated taking into account the sensitivity coefficients when determining different AO at a selected wavelength (interval estimate according to V.I. Vershinin). It was established that the analytical signals of the model AO obeyed the Beer-Lambert-Bouguer law in the range of 10–6–2.10–5 mol/l, and were measured with a relative standard deviation not exceeding 10 %; deviations from the light absorption additivity of AO mixtures were statistically insignificant. As in the photometry of solutions, the sensitivity coefficients of different AO were different, and the differences decreased when using «normal» concentrations. The modulus of the relative error in estimating ΣAO in model mixtures, even when using optimal standards (luteolin), reached 17%. The possibility of interval estimation of ΣAO from generalized analytical signals measured by the CUPRAC method using PMM matrices was shown. The boundaries of the intervals practically did not depend on the standards used during the calculation. For all mixtures the actual values of ΣAO were within the boundaries of the corresponding intervals. The results of the group analysis of fruit and berry juices before and after their dilution confirmed the approximate correctness of the results obtained both by method (a), i.e. in terms of luteolin, and by method (b), i.e. in the interval form. Unfortunately, the width of the intervals that take into account the intragroup signal intensity was an order of magnitude larger than the width of the confidence intervals calculated from the results of repeated measurements of generalized signals (Student's test, n = 3, P = 0.95). This indicates the necessity of leveling the sensitivity coefficients for different AO. Thus, both methods of calculation are suitable for the group analysis of juice products, but method (b) leads to more reliable, more metrological correct, but less unambiguous estimates of the total content of the antioxidants.

In Republic of Belarus and the countries of the EACU, the synthetic dye E 127 (erythrosine) is prohibited for the use in the production of food products. To control the content of this additive, accurate and rapid methods of determination are required. In order to develop a methodology for determination of erythrosin in the presence of food synthetic dyes (E 102, E 104, E 110, E 122, E 123, E 124, E 128, E 129, E 131, E 132, E 133, E 142, E 143 , E 151, E 155) the extraction of dyes with organic solvents from aqueous solutions was studied and their distribution coefficients were determined. Based on the data obtained in the presence of the above dyes, a method for determining E 127 without the use of expensive chromatographic equipment was proposed. The technique is based on sample preparation, which consists of the selective extraction of E 127 from an aqueous solution of the food matrix (pH=2) using chloroform. Other synthetic dyes were not extracted. Next, the extract was evaporated, dissolved in a buffer solution at pH=9 and photometrically measured at the wavelength of 527 nm. In the presence of hydrophobic organic dyes (carotene, lycopene) in the food matrix, their preliminary extraction was carried out from the aqueous solution at pH=9 with chloroform; under these conditions all dyes, including E 127, were not extracted. The limit of quantitative determination by the proposed method for liquid food products was 0.05 mg/kg, for solid – 0.13 mg/kg, the standard deviation was 2–3 %.

Recently, in the economy, in connection with the transition to a digital economy, the terms digital platforms and ecosystems are often used. The concept of an ecosystem appeared in ecology to emphasize the role of the interconnectedness of all biological processes. However, it turned out that consistency and interconnectedness is important not only in nature, but also in business. The development of digital technologies has led to the description of business processes in the form of ecosystems. The article provides a systematic analysis of the concept of an ecosystem. Their classification is given, types and properties are described. The economic ecosystem is a collection of interconnected companies that form a single whole. Ecosystems include producers, suppliers and consumers united by collaborative processes. Digital ecosystems come together on a single digital platform. For digital ecosystems, the issue of their sustainability is considered. From the point of view of creating digital ecosystems, public and private ecosystems can be distinguished. In the digital age, the traditional collaboration networks of firms have gradually evolved into a new ecosystem with cross-industry and complementary characteristics. Digital ecosystems are often made up of multiple complementary firms that work together to achieve a common value proposition. The studies conducted in the article show that the creation of private ecosystems is more sustainable with state support for digital development. The technological features of transport ecosystems are also described. The transport ecosystem is the lifeblood of the city. The basis of the transport ecosystem of the city are railways and metro. Transport ecosystems are integrated with economic and reference ecosystems.

The article provides a comparative analysis of the effectiveness of the sphere of circulation and use of municipal solid waste in the Russian Federation and the Federal Republic of Germany. The characteristics of the legal regulation of both countries in the field of waste management are given. Legal acts adopted in the European Union are the basis of German legislation in the field of waste management. Comparison of the legislative framework of Russia and Germany revealed their significant difference. Noteworthy is the lack of a clear hierarchy in the handling, disposal and processing of MSW. Attention is drawn to the huge number of illegal landfills and waste incineration sites in Russia. In our country, composting has not become widespread enough, and it is usually used by the population in individual houses or garden plots. However, the composting process can also be centralized and carried out at special sites, which are organic waste processing plants. The end product of this process is compost, which can be used in various agricultural applications. The main ways of improving the legal regulation in the field of waste management are proposed. In particular, it is recommended to develop a complete waste management strategy and a roadmap for its implementation. The waste management strategy in Russia should be based on a model that takes into account the specifics and cost-effectively combines the collection, transportation, processing, recycling and disposal of waste. It is necessary to create universal centers that unite enterprises for the collection, storage, recycling, processing and marketing of garbage and materials produced from waste coming from the largest cities of Russia. In the short term, the key goal is to solve the problem of the formation of illegal dumps, as well as landfills near large cities.

Published: October 2023

In this work, aluminum oxide nanoparticles were fabricated by two physical methods: laser ablation in liquid medium and plasma discharge under the action of intensive ultrasonic cavitation. Dynamic light scattering, scanning electron microscopy, and electrokinetic potential measurements were employed to comparatively examine the nanoparticles obtained by both methods. It was found that the synthesized particles had spherical shapes with a size range of about 50-70 nm and relatively narrow particle size distributions and were stable to aggregation and sedimentation. The electrokinetic potential values of the pure particles and the effects of the presence of water-soluble polymer polyethylene glycol were used to examine the surface properties of the nanoparticles. This study demonstrates the
effect of ultrasonic action on particle surface activity.

Ausencia de varones en Educación Infantil: una cuestión de masculinidades
Authors: Martín Vidaña David
Published: October 2023

Actualmente, la escasa presencia de varones maestros en Educación Infantil comprende una realidad fácilmente constatable. Los datos ofrecidos por la Organización para la Cooperación y el Desarrollo Económico (2023) indican que España no supera el 6% de profesionales varones dedicados a este sector. No obstante, las transformaciones sociales proclamadas en materia de igualdad de género han permitido incorporar a un número reducido de hombres en el universo de los cuidados. El objetivo de la presente investigación consiste en mostrar una panorámica general de la situación que ocupan los varones maestros de Educación Infantil en el contexto actual, marcada por resistencias de carácter sociocultural e ideológico. Para ello, se parte de literatura científica que permita conocer la situación actual que atraviesa esta profesión, altamente feminizada y desprofesionalizada, y se analizan los datos ofrecidos por la OCDE, el Instituto Nacional de Estadística y los anuarios de las Universidades de Granada y Jaén. Como conclusión, cabe destacar la necesidad de poner en tela de juicio los prejuicios, comportamientos y actitudes existentes que limitan la incorporación de varones en centros de Educación Infantil, así como analizar las expectativas y mejoras que producen su incorporación para la profesionalización de este sector.

Esta investigación trata de resolver si el valor predictivo de la orientación en el último curso de bachillerato se da a partir del aspecto multicultural y socioeconómicos influyentes. la calidad educativa del centro, el género del alumnado y las influencias de las variables socio-académicas de los progenitores en sus hijos. La desorientación vocacional, la deserción del alumnado cuando llega a estudios superiores, la falta de información en la elección de la carrera académica, están siendo cada vez más acuciantes. La importancia social de la cuestión radica en el lugar clave que ocupa la calidad de la orientación educativa en este tránsito y máxime, en contextos multiculturales. La muestra es de 437 alumnos de diferentes institutos de la Ciudad Autónoma de Melilla. Se utilizó la técnica del modelo de regresión múltiple lineal. Los análisis muestran que el modelo tiene un coeficiente de bondad de ajuste de R2 corregida: 0.368 con p < 0.05. Se ha obtenido como resultados que el aspecto multicultural es la variable predictiva más destacada, seguida de la calidad de la enseñanza del centro y la influencia socio-académica de los padres y madres quedando excluida la variable género en el modelo predictivo.

Aim. To study the features of the course of COVID-19 in pregnant women, the outcomes of a new coronavirus infection and pregnancy, the effect of concomitant pathology on the severity of the course and the frequency of complications of COVID-19.

Materials and methods. In the course of the work, a retrospective analysis of 109 medical histories of pregnant women who were treated in the infectious diseases department in 2021 with a diagnosis of COVID-19 was carried out. Anamnesis, concomitant pathology, results of objective examination, laboratory and instrumental methods of research, therapy, complications, outcomes of COVID-19 and pregnancy were evaluated.

Results. The majority of pregnant women had moderate – 55 % and severe – 24 % COVID-19, 7 % – extremely severe and only 14 % – mild. A third of pregnant women had concomitant pathology, arterial hypertension was the most common; 80 % of pregnant women had complications of COVID-19: cytokine storm – in 50 % of patients, acute respiratory distress syndrome – in 17 %, of which 5 % required artificial lung ventilation. The mortality rate was 4.6 %. The structure of pregnancy complications was dominated by gestational hypertension, gestational diabetes, premature placental abruption, preeclampsia. Complications of childbirth – premature birth and premature discharge of amniotic fluid. However, in most cases, pregnancy (75 %) and childbirth (71 %) proceeded without complications. Women in 95 % of cases were discharged from the hospital with recovery or significant clinical improvement.

Conclusion. Despite the prevalence of moderate and severe forms of COVID-19 in pregnant women, a high percentage of concomitant pathology and complications, in most cases favorable outcomes of both COVID-19 and pregnancy were noted. The presence of hypertension syndrome should probably be considered as a prognostically unfavorable marker of severe course and adverse outcomes of COVID-19 in pregnant women.

The era of the Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) virus has shown that non-core specialists can be involved in the treatment of epidemic diseases. However, the entire burden for the prevention and treatment of venous thromboembolism (VTE) falls on doctors – cardiovascular surgeons, phlebologists. It should be borne in mind that most of the thromboses – more than 2 million cases per year – are asymptomatic, and only a small part has pulmonary embolism, pulmonary hypertension, and death. The survival rate of patients with deep vein thrombosis (DVT) for 8 years is 65 %, with a combination of DVT with pulmonary embolism; the survival rate does not exceed 34 %, so a doctor of any specialty should know how to suspect VTE. The clinical picture of DVT is not always pronounced. Most often, with DVT, patients complain of swelling and pain in the affected lower limb, a decrease in the volume of active movements, and skin cyanosis. Diagnosis of DVT and thromboembolic complications at the non-specialized level should initially consist of assessing the risk of VTE using special scales, among which the Wales scale is of the greatest importance. The gold standard for diagnosing DVT is duplex ultrasound. Among the main indicators for hospitalization is not the fact of the established diagnosis of DVT, but the presence of comorbid pathology, chronic lung diseases, and old age. Additional risk factors include extended DVT, suspected pulmonary embolism, and pregnancy. The goal of anticoagulant therapy is to stop the process of pathological hypercoagulability, the progression of thrombus formation and create conditions for restoring vascular patency, while the pathological idea is that anticoagulants “dissolve the thrombus”. In this regard, anticoagulant therapy is the mainstay of treatment for DVT. To determine the duration of anticoagulant therapy, the etiology of thrombosis is of particular importance – the trigger that led to the formation of thrombotic masses.

The article proposes an algorithm for the synthesis of reconnaissance and fire systems. Which allows you to justify the need for weapons samples for the completion of subsystems of fire damage and reconnaissance of the specified systems. The essence of the algorithm is to organize the stages of determining the need for weapons samples to ensure the effective functioning of reconnaissance and fire systems. The advantage of the algorithm is that it allows you to take into account the stability of functioning and the capabilities of each type of weapon based on the tasks that rely on the reconnaissance and fire system. This ensures the optimal distribution of weapons and prevents overspending of resources. At the same time, the algorithm is universal and ensures work with all types of means of fire damage and reconnaissance that are in service in the missile forces and artillery of the Armed Forces of Ukraine, taking into account those that are being modernized or developed, as well as those that come as aid from Western countries - partners. In addition to the fact that the proposed algorithm determines the need for weapons when creating new reconnaissance and fire systems, taking into account the given degree of task performance, it also allows determining the degree of performance of assigned tasks, taking into account the available forces and means. The algorithm is based on an improved method of nonlinear programming (two functions), which allows you to take into account both the heterogeneity of types of weapons and military equipment, and the heterogeneity of targets. The improvement consists in determining the "weight" of the types of fire weapons depending on the "weight" of the targets to be hit they are involved. And in the future, normalized fractions of this "weight" are used as weighting coefficients. This makes it possible to justify the need for weapons samples taking into account the given level of performance of the assigned tasks. The defined algorithm allows taking into account the nonlinearity of the functions that describe different types of weapons and targets.

The article analyzes the effectiveness of the neural network control system, which together with the PIDcontroller implements the principle of parallel control of a dynamic object. As a rule, most industrialfacilities are characterized by non-linear dependencies, the presence of uncontrolled noise anddisturbances, frequent changes in equipment operating modes, and the presence of significant non-linearities. The model of the blowing subsystem of a water-tube steam boiler was used as an object ofresearch. The training of the neural network controller (NMC) and neuroemulator (emulator) was carriedout on the ACS model with a PID controller using the method of expert adjustment of tuning coefficients:proportionality, constant integration and differentiation based on the analysis of the quality indicators ofthe transition process. The change in the values of the object model parameters along the control anddisturbance channels corresponded to the dynamic modes of operation of the steam boiler in the range ofsteam load (25-110%) from the nominal one. The analysis of transient processes obtained on the basis ofcomputer modeling allows us to assert that the trained neural network control system compensates fordisturbances over the entire range of changes in the values of the object parameters along the control anddisturbance channels (simulation of changes in the steam load), as well as when the parameter values ofthe models go beyond the range study sample. Thus, the neural network controller can successfully perform the functions of an adaptive circuit tuned tothe most unfavorable disturbances in the ACS of parallel action by a complex production facility. And theimplementation of a neural network system of parallel action together with typical regulators in thetechnological processes of heat energy can reduce emergency situations associated with frequent changesin the steam load of power units caused by military actions in our country.
Una aproximación a la fiscalidad sobre la vivienda en Roma
Authors: Azaustre Fernández María José
Published: October 2023

El presente artículo aborda el estudio de los diferentes impuestos que grabaron la vivienda a lo largo del Derecho romano, tanto los que afectaron a su adquisición -inter vivos y mortis causa- como los derivados de su tenencia, incluyendo aquellos impuestos que recaían sobre algunos de sus elementos constructivos, y teniendo en cuenta, respecto a todo ello, las diferentes etapas del ordenamiento jurídico romano, así como la ubicación de la vivienda en suelo itálico o provincial.
Dos avances jurídicos importantes de la civilización romana, en materia de obligación
Authors: Suárez Blázquez Guillermo
Published: October 2023

Con este estudio investigamos las causas histórico – jurídicas que hicieron surgir y evolucionar el concepto jurídico corporal al concepto jurídico abstracto de obligación. Este último supuso la eliminación de la idea de un poder personal del acreedor y de presidio, cadenas y sujeción corporal del deudor. Analizamos, además, el desarrollo de la ejecución personal del sometido, su esclavitud, e incluso muerte para satisfacer la pretensión de su acreedor, así como el cambio hacía un sistema de responsabilidad exclusivamente patrimonial y universal. Ambos avances fueron fruto del “pensamiento de la civilización jurídica romana”, quien actuó, durante siglos, en diversas direcciones, legislativa, procesal y jurisprudencial. Estas bases, sólidas e imperecederas, del derecho de obligaciones han pasado a nuestros ordenamientos civiles modernos. Concretamente, el artículo 1008 de nuestro Código Civil dispone: “Toda obligación consiste en dar, hacer o no hacer alguna cosa”; Y el artículo 1911: “Del cumplimiento de las obligaciones responde el deudor con todos sus bienes presentes y futuro”.
La reserva de la cuarta parte en la legislación justinianea: la cuarta falcidia y la portio debita
Authors: Vázquez Lemos Ana
Published: October 2023

La promulgación de la Ley Falcidia en la etapa clásica no dio lugar a la aparición de los herederos forzosos en Roma, lo que se impuso fue una reserva obligatoria de una cuarta parte de la herencia para garantizar su aceptación del heredero instituido en el testamento. Esta interpretación se mantuvo en la época postclásica justinianea donde además, aparecieron otros casos de reserva de la cuarta parte como la cuarta fiscal en el caso de matrimonios  entre parientes  o la cuarta curial, de acuerdo con la cual, una cuarta parte de la herencia de los decuriones debía ir a parar necesariamente a la Curia. La institución de heredero era totalmente libre, no obstante, en algunos casos, cuando se instituía colectivamente herederos a los hijos o nietos, estos tenían derecho a una porción en esa cuarta parte en función de su número. Esta fue la portio debita iure naturae. Y Justiniano aumentó la porción global que le correspondía a los hijos cuando eran nombrados colectivamente, dependiendo de si eran más o menos de cuatro.

El mecanismo de cuello robótico presentado en este trabajo tiene como elemento principal un eslabón blando que emula un cuello humano con dos grados de libertad (DOF) (flexión, extensión y flexión lateral). El dispositivo se basa en un Mecanismo Paralelo Accionado por Cable (CDPM). Se desarrolla una cinemática directa a partir del sistema estático y la distribución geométrica del mecanismo, y se presentan ecuaciones lineales que permiten conocer fácilmente la longitud de los cables para hallar la posición del cuello, tanto en ángulos de inclinación como de orientación. Para el control del motor se utiliza un controlador PI de orden fraccionario (FOPI).
