The pathology of the processus vaginalis of the peritoneum (inguinal hernia, hydrocele testis) is quite widespread among the pediatric population, both in our country and throughout the whole world. More than 99% of inguinal hernias in children are oblique, right-sided localization is more than 3 times more common than left-sided. High interest of scientists in the study of the pathology of the processus vaginalis of the peritoneum is caused by data on the appearance of infertility as a complication of inguinal hernias and dropsy of the testicles. In the structure of the causes of this situation, 30% belongs to the male factor, and this percentage has a constant tendency to increase. This became the reason for an additional study of the mathematical component of the prevalence of the pathology of the processus vaginalis of the peritoneum among the children’s population. Purpose - to create a mathematical model of the prevalence of pathology of the processus vaginalis of the peritoneum depending on age and gender among the children’s population. Materials and methods. 205 patients under the age of 18 who underwent surgical correction of the pathology of non-obliterated processus vaginalis of the peritoneum (inguinal hernia, hydrocele testis) took part in the conducted scientific study. For mathematical modeling, software built into Microsoft Excel was used (Trend line, polynomial regression equation of the 4th degree). Results. In the course of mathematical modeling, characteristic features were identified: they occur both in the female part of the pediatric population and in the male, similar fluctuations are noted in the general pediatric population, namely periods of increase in the frequency of pathology of the vaginal peritoneum, which alternate with periods of its decline. a rapid increase in the frequency of pathology of the vaginal peritoneum, and, accordingly, their surgical correction, in children under 3-4 years of age, followed by a decrease in frequency by the age of 11-13 years. The following slight increase in the frequency of diagnosis of pathology of the vaginal peritoneum and its surgical treatment was detected by the age of 15-16 years, followed by a gradual decrease in the frequency by the age of 18 years Conclusions. Therefore, there are two mathematically confirmed peaks of growth in the frequency of detection of the pathology of the processus vaginalis of the peritoneum, which fall on the age of verticalization of the child and the age of “specialized” loads. 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 participating institution.

Allergic rhinitis (AR) is a common immunoglobulin E (IgE) dependent disease among allergic patients worldwide. At the same time, the determination of specific IgE in the blood serum allows characterizing the relevant sensitizing allergens. Despite the existence of conditional thresholds for normal and elevated levels of total and specific IgE, there is no consensus in the literature on which IgE value unequivocally confirms the presence of atopy and what is the relationship between these levels and the severity of clinical manifestations. Purpose - to evaluate the levels of serum total and specific IgE and their relationship with severity and age in children with persistent AR and combined with bronchial asthma (BA) during sensitization to house dust mite (HDM) allergens. Materials and methods. A clinical, anamnestic and laboratory examination of 259 children aged 5 to 17 years with AR and combined AR with BA, who were sensitized to HDM allergens, was conducted. Results. In AR in children with sensitization to HDM, there is a dependence of serum total IgE level on the severity of AR and age of children. With increasing severity of AR manifestations, a significant (p<0.05) increase in total IgE levels was noted. It was found that the content of sIgE also increased with increasing severity of AR. Thus, statistically significantly (p<0.05) higher levels of sIgE were determined in sensitization to the major HDM molecules Der f 1, Der p 1, Der p 2, Der p 23 in children with severe AR. Sensitization to the tropomyosin Der p10 molecule, which usually has no effect on the clinical manifestations of respiratory allergy but indicates cross-reactivity to seafood, was significantly more common (p<0.05) in children aged 3-7 years compared to children aged 13-17 years. Conclusions. The data obtained partially define the pathogenetic features in the formation of sensitization to HDM and their individual molecules, confirming that this process begins at an early age, which may indicate the need to start allergen-specific immunotherapy in such children if clinically necessary. 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.

Pectus excavatum (PE) is the most common congenital chest deformities. For many patients, this defect caused significant psychological stress which occurs in adolescence and lead to anxiety, low self-esteem and withdrawal from social activities, which significantly affects the quality of life. The need of surgery often accompanied by a patient’s psychological trauma, especially for children. Purpose - to evaluate the role of correction of psycho-emotional disorders in children with PE before surgical intervention to improve treatment results. Materials and methods. Assessment of preoperative anxiety in 28 children aged 10 to 17 years was carried out. The Group I included 11 children who were psychologically ready for surgery, the Group II included 17 children who needed the help of a psychologist. Assessment was performed using the Preoperative Anxiety Scale (SAS) and the Anxiety Inventory for Children (STAIC). Psychotherapeutic correction included: information support, relaxation and physical exercises, game and art therapy. Statistical analysis was performed using SPSS 26.0. Results. After the preliminary survey, most of the children who agreed to the operation had a low or moderate level of anxiety, while the children who needed psychological help had a high level of anxiety. Before psychological correction, according to the results of the STAIC questionnaire, 64.3% of patients had a high level of situational anxiety and a high score of personal anxiety. After completing the course of psychological correction, personal anxiety in 57.1% of children decreased to a low level. Conclusions. Psychological therapy reduces psychological, psychosomatic and psychophysiological symptoms in patients, helps patients prepare for surgery. The research was carried out in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of the participating institution.

Anxiety disorders are the most prevalent psychiatric disorders and are associated with a high burden of illness. Combining synthetic and native-origin compounds in treating such disorders could provide true benefits in terms of therapeutic efficacy. In the present study, we combined triazolobenzodiazepine and motherwort (Leonurus cardiaca L.) dry extract for such applications.

The aim. The aim of this study was to develop aqueous polyethylene oxide (PEO) composite gels loaded with 1,2,3-triazolo-1,4-benzodiazepine nanofibers and a valine-modified motherwort herb dry extract for semi-solid extrusion (SSE) 3D printing. The printability of such gels and the physicochemical properties of the final 3D-printed drug preparations were investigated.

Materials and methods. A new drug substance, 1,2,3-triazolo-1,4-benzodiazepine (MA-253) was synthesized and used to formulate oleogels and electrospun nanofibers for 3D printing. The plant-origin dry extract was prepared from a motherwort tincture and valine. The aqueous PEO gels loaded with a synthetic drug (MA-253) containing nanofibers and a valine-modified motherwort extract were prepared and subsequently used in the SSE 3D printing experiments. The homogeneity, viscosity and 3D printability of composite PEO gels were verified. The phytochemical assay of flavonoids in the 3D-printed drug preparations was conducted with the European pharmacopoeia spectrophotometric method.

Research results. Three experimental gel formulations loaded with 1,2,3-triazolo-1,4-benzodiazepine nanofibers and a valine-modified motherwort dry extract were developed and tested for the SSE 3D printing applications. The present three gels showed good SSE 3D printability without any significant printing flaws. The SSE 3D-printed lattices prepared from the aqueous PEO gels containing 100 mg/ml of motherwort extract showed the most promising 3D printing performance. The 3D-printed drug preparations were entirely dissolved in purified water (22±2 °C) within 20 minutes, thus suggesting their applicability in oral administration.

Conclusions. Novel aqueous PEO gel formulations loaded with nanofibrous 1,2,3-triazolo-1,4-benzodiazepine nanofibers and valine-modified motherwort herb extract are feasible for pharmaceutical SSE 3D printing. The present composite PEO gels enable the preparation of printed oral immediate-release drug delivery systems for new triazolobenzodiazepine derivatives and a drug therapy supportive plant extract

Published: March 2024

The subject of the study is sustainable reverse engineering and conventional reverse engineering of aviation equipment (AE) samples. The object of the study is the geometric accuracy of the extracted portrait of a part of a complex shape in comparison with the constructed analytical standard (AS). The work is aimed at researching the methods of sustainable reverse engineering and conventional reverse engineering on the example of the digitization of the box of the AE steering machine, chosen as a part of a complex shape. For this, a portrait of the "*.stl" and AS format file was created and compared by performing a control operation with the determination of the time spent. A structural and technological analysis of the box of the AE steering machine was carried out, which showed that the box has through holes of various diameters (from 10 to 41.6 mm) and shapes (square, trapezoidal, round); thin walls between holes (up to 1.6 mm); right angles and their rounding radii (up to 1–4 mm); the thickness of the body walls is 2.4 mm, etc. 3D scanner – ARTEC SPACE SPIDER (Luxembourg) was selected and scanning was performed. According to the analysis of research methods of reverse engineering, it was established that the use of permanent and conventional reverse engineering allows, in the first case, to quickly manufacture a part by 3D printing or milling on CNC machines, and in the second case, to create its AS with the provision of the specified geometric accuracy. The difference in time between permanent and normal reverse engineering was 8 hours in favor of the former. Control of the ideal portrait according to the AS of the AE steering machine body showed the maximum deviations from –0.30 mm to +0.23 mm and the minimum deviations from –0.04 mm to +0.08 mm. The smallest indicators were observed on vertical and horizontal planes, and the largest - in cities with plane slopes, corners and small radii. This made it possible to establish that the existing capabilities of the Geomagic Design X software for correcting the received portrait of the "*.stl" format file currently do not guarantee the provision of geometric accuracy requirements (up to ±0.5 mm) for the manufacture of an experimental part of a complex shape – the AE steering machine body with 3D printing. The resulting ideal portrait can be used to manufacture a part by milling on CNC machines, taking into account deviations at the stage of process model formation, which can become the topic of further research.

Published: March 2024

The establishment of a new metallurgical complex in Bellara, located in El-Milia in the Jijel region, is geographically advantageous due to its proximity to the Sidi Maarouf deposit (Algeria). This proximity has been a fundamental motivation for the completion of the current study. The object of research is the quality of iron products from Sidi Maarouf. The research is aimed at developing a treatment process aimed at improving the quality of iron products from Sidi Maarouf, while reducing the impurities of quartz and clay present in this ore. This approach will be based on an approved technological treatment scheme, implemented through an experimental approach to ensure reliable results that meet the requirements of the steel industry. The problem issue revolves around the difficulties encountered in the production of steels due to the natural characteristics of the raw material.
In the absence of a physico-chemical characterization of the Sidi Maarouf iron ore deposit, samples taken undergo a series of thorough analyses, including microscopic examinations, X-ray diffraction (XRD), as well as additional chemical analyses using X-ray fluorescence (XRF). The identified minerals are predominantly composed of hematite in terms of iron. As for the gangue, it is mainly composed of calcite and quartz. Through to the pre-treatment process involving washing, we have successfully removed lightweight particles, resulting in a concentrate containing dense particles. This approach was crucial in achieving satisfactory results during the high-intensity dry magnetic separation. As a result of the research it is shown that the enrichment of the Sidi Maarouf iron ore through high-intensity dry magnetic separation, a final concentrate was obtained with a Fe2O3 content exceeding 67 %, along with a significant reduction in silica impurities to 0.92 % and alumina to 0.77 %. It was concluded that this concentrate, derived from the -1+0.5 mm fraction and obtained under a current intensity of 12 A, meets the requirements of the steel industry.
Following the work carried out, it is found that the methods of valorization of iron ore through mineralogical processes consistently require a high level of efficiency and performance in terms of equipment and characterization of the products obtained. In the future, iron ore processing will be conducted using innovative methods, integrating advanced technologies to enhance its characteristics while adopting environmentally friendly practices.

The results of the work include the concept of designing aircraft with a transonic truss-braced wing, the main advantages of such a scheme, the process of determining the geometric parameters of the truss-braced, features of the preliminary design of an aircraft with an extremely high aspect ratio truss-braced wing, possible approaches to the arrangement of units and their mutual arrangement. The results are explained by the difference in the design model (the cantilever beam is replaced by a beam on two supports) in mass analysis and the increased wing aspect ratio in aerodynamic calculation. The final data are based on a statistical study to determine the basic geometric parameters of assemblies of modern mainline passenger aircraft, synthesis of parameters of analog aircraft. For example, an aircraft capable of carrying 250 passengers over a distance of 13.000 km is considered. In the design process, values of aspect ratio, taper ratio, wing area, vertical tail and horizontal tail area ratio, and fuselage dimensions are accepted. Drawings of the general appearance of the aircraft have been developed and, based on it, a master geometry of the theoretical contour has been constructed. Graphs of first-order polar and maximum lift-to-drag ratio have been plotted, the reduction of aerodynamic drag in percentage terms has been determined, and the increase in aerodynamic lift-to-drag ratio in percentage terms for an aircraft with an extremely high aspect ratio truss-braced wing compared to similar characteristics of an aircraft with a conventional non-braced wing has been calculated. The approximate mass savings when using a truss-braced wing on the aircraft are determined in percentage terms. The expediency of using wings of greater aspect ratio, than modern aircraft currently have, has been justified. The expediency of using a brace for the aircraft with an extremely high aspect ratio wing has been justified. The obtained results can be used in practice in the process of developing the preliminary design of an aircraft with a truss-braced wing or in the modifications of existing aircraft to increase their fuel efficiency or increase the durability of wing elements due to reduced loads acting on them.

The object of this research is the role of organizational tools in enhancing the efficiency, productivity, and overall performance of marketing teams.
Despite the immense potential of organizational tools to revolutionize marketing operations, many teams fail to take full advantage of their benefits. This is due to a combination of factors, including lack of awareness, where a significant proportion of marketing teams are unaware of the vast array of organizational tools available and their potential to improve productivity. And a lack of training, where even when teams are aware of these tools, they often lack adequate training or guidance on how to integrate and use them effectively. And cost concerns, where the perceived high cost of organizational tools often deters teams from investing in these technologies.
The research indicates that organizational tools provide significant benefits to marketing teams, including improved efficiency through task automation, streamlined workflows, and centralized information access, as well as enhanced productivity through improved collaboration, data-driven decision-making, and project management capabilities. Effective marketing efforts supported by organizational tools can boost performance, resulting in improved customer engagement, increased ROI, and overall business growth.
This paper aimed to provide marketing teams with a comprehensive insight into the benefits and applications of organizational tools. It is examined the wide range of organizational tools available and provides guidance on selecting the most appropriate tools to meet specific marketing needs. In addition, the paper addressed common challenges that marketing teams face in adopting and maximizing the effectiveness of organizational tools.

The object of the research is the response of a structure in time between formulations, namely force-based (flexibility-based) and displacement-based.
An existing two-story reinforced concrete structure subjected to three earthquakes separately is presented in order to carry out a comparative study in terms of time history structure response between the two formulations cited above namely force based (flexibility based) and displacement based.
This research aimed to compare between two formulations namely displacement based and force-based (flexibility-based), in order to show the accuracy and the reliability of the second one. In the case of nonlinear time history response of a residential two-storey reinforced concrete building, which is representative of typical residential building construction in Italy in the 1970’s and 1980’s with the aim of taking advantages of flexibility-based formulation if the comparison proves conclusive.
In the course of the research, the former approach is a classical two-node, displacement-based, Euler-Bernoulli frame element with the disadvantage of discretizing the structure thus increasing the number of degrees of freedom and equation, in order to achieve the required precision. The latter is a two-node, force-based, Euler Bernoulli frame element. The main advantage of the second element is that it is «exact» within the relevant frame element theory. This implies that one element per frame member (beam or column) is used in preparing the frame mesh, thus leading to a reduction of the global number of degrees of freedom. Therefore, a reduction in number of equations to solve, resulting in a saving of time with increased precision.
An existing two-story reinforced concrete structure subjected to three earthquakes separately is presented in order to carry out a comparative study in terms of time history structure response between the two formulations cited above namely force based (flexibility-based) and displacement-based. As a result of the research, it is shown that with flexibility-based approach no discretization error occurs and all governing equations are satisfied exactly, making a possibility of simpler and faster numerical modeling. In the proposed approach will be of great use in the field of numerical modeling due to its ease and accuracy. This elegant formulation is promising for future work thanks to its advantages.

Access to transportation may be required for many daily tasks, including going to work, health care visits, and obtaining groceries. Previous research suggests that a lack of transportation, especially among adults who are older, uninsured, and have lower incomes, leads to reduced access to health care, which may then lead to adverse health outcomes (1,2). Using data from the 2022 National Health Interview Survey, this report describes the percentage of adults who lacked reliable transportation for daily living in the past 12 months by selected sociodemographic and geographic characteristics. Key findings Data from the National Health Interview Survey ● In 2022, 5.7% of adults lacked reliable transportation for daily living in the past 12 months. Women (6.1%) were more likely than men (5.3%) to lack reliable transportation. ● The percentage of adults who lacked reliable transportation was lowest among Asian non-Hispanic adults (3.6%) compared with other race and Hispanic origin groups. ● Lack of reliable transportation decreased with increasing education level and family income. ● Adults living in the West North Central region of the United States (7.5%) were more likely to lack reliable transportation than the national average (5.7%), while adults in New England (4.1%) were less likely

We concur with the authors of the two target articles that Open Science practices can help combat the ongoing reproducibility and replicability crisis in psychological science and should hence be acknowledged as responsible research practices in hiring and promotion decisions. However, we emphasize that another crisis is equally threatening the credibility of psychological science in Germany: The sampling or generalizability crisis. We suggest that scientists’ efforts to contextualize their research, reflect upon, and increase its generalizability should be incentivized as responsible research practices in hiring and promotion decisions. To that end, we present concrete suggestions for how efforts to combat the additional generalizability crisis could be operationalized within Gärtner et al. (2022) evaluation scheme. Tackling the replicability and the generalizability crises in tandem will advance the credibility and quality of psychological science and teaching in Germany.
