Acute flaccid myelitis is a syndrome characterized as the development of acute flaccid paralysis of one or more limbs due to lesions of the anterior horns of the spinal cord, which occurs against the background of a viral infection. More than 300 acute flaccid paralysis cases are registered in the Russian Federation annually, most of them are of a non-infectious etiology. In some cases, patients develop a complex of symptoms similar to poliomyelitis, but without isolation of polioviruses from stool samples. Clinical characteristics of such cases include acute onset, fever, persistent peripheral asymmetric paresis/paralysis of predominantly proximal parts of the limbs, and absence of pathological reflexes, pelvic disturbances, or pyramidal symptoms. In literature, such complex of symptoms is referred as acute flaccid myelitis. We provide an analysis of 18 cases of acute flaccid myelitis detected in the Russian Federation in the period from 2015 to 2019. A clear seasonality of the disease from July to November was noted. Studies of faecal samples, cerebrospinal fluid and blood samples did not reveal the pathogen. In all patients, regardless of therapy, there was a positive trend, but complete recovery was not achieved: paresis of varying severity persisted, mainly in the proximal extremities Therefore, acute flaccid myelitis cases as acute flaccid paralysis cases of unknown etiology require an additional observation and an expanded algorithm of laboratory investigation aimed to finding a possible pathogen.

Craniofacial dysmorphia-deafness-anomalies of the upper limbs is a rare autosomal dominant syndrome caused by variants in the PAX3 gene. In contrast to the two main nosological forms – Waardenburg syndrome types 1 and 3, caused by variants in this gene, the syndrome of craniofacial dysmorphias-deafness-anomalies of the upper limbs is not characterized by the presence of hair hypopigmentation and heterochromia of the iris, while congenital contractures of the wrist and interphalangeal joints of the hands. There is a description in the literature of three patients from the same family with a syndrome caused by the c.141C>G(p.Asn47Lys) variant in the PAX3 gene. Aim of the work is to present the clinical and genetic characteristics of the first Russian patient with the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper extremities.

Molecular genetic analysis of a 1-year and 10-month-old proband with phenotypic signs of the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper limbs was carried out by direct automatic Sanger sequencing of the entire coding sequence of the PAX3 gene. Genotyping of parents was carried out by direct automatic sequencing according to Sanger. Sequencing was carried out on an ABIPrism3500хI instrument (Applied Biosystems) in accordance with the manufacturer’s protocol; primer sequences were selected according to the reference sequence of the target regions of the PAX3 gene (NM_181459.4).

In Russian proband 1 year 10 months-old, the phenotypic characteristics of the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper limbs did not differ from the description of sick family members presented in the literature. A molecular genetic study revealed a heterozygous variant c.141C>G(p.Asn47Lys) in the PAX3 gene in the presented patient.

Authors: Misikov V. K. , Kovalenko A. P. , Kondur A. A.
Published: November 2023

Dystonic scoliosis as one of the forms of generalized dystonia is a highly disabling form of dystonia, which can lead to damage to internal organs (lungs, heart) and the peripheral nervous system, including the spinal cord. Almost always, those muscles that are involved in the formation of a dystonic posture in generalized dystonia have not been studied in terms of the effectiveness of treatment with botulinum toxin type A and are not reflected in the instructions. As a result, there is no understanding of the general motor interaction with differentiation into targeted and non-targeted muscles, administration doses and control methods.

The aim of the work was to evaluate the efficacy and tolerability of high doses of botulinum toxin type A in dystonic scoliosis, as well as to present the introduction of botulinum toxin type A using ultrasound and electromyographic control. We have described a clinical case of a 19-year-old patient suffering from generalized dystonia with S-shaped dystonic scoliosis of the III degree. Deep brain stimulation was recommended as a treatment for the patient. During the waiting period for the timing of the operation, we attempted symptomatic therapy using the drug incobotulotoxin A. Over the next year and a half, 700 units of botulinum toxin type A were administered under ultrasound and electromyographic control every 3–4 months. As a result, treatment of trunk dystonia in the patient during the observation period led to a clinically significant decrease in the degree of curvature (from 37° to 27°, from III to II degree of scoliosis) in the absence of undesirable effects of the drug, including generalized muscle weakness. According to the repeated conclusion of the council of neurosurgeons, surgical intervention is not indicated for the patient due to the positive effect of the introduction of botulinum toxin type A.

Aim: to identify specific associations between genes polymorphism associated with sex hormone-binding globulin (SHBG) level and breast cancer (BC) of various molecular biological subtypes.

Materials and Methods. The retrospective comparative study was conducted using specimens collected from 261 patients with BC of two molecular biological subtypes – luminal A/B (n = 153) and triple negative (n = 108) as well as 1140 women in control group. All study participants (n = 1401) underwent a molecular genetic study of four single nucleotide polymorphism (SNP) loci, which showed a relationship with circulating SHBG level in previously conducted genome-wide association study (GWAS): rs12150660 SHBG, rs10454142 PPP1R21, rs780093 GCKR, rs17496332 PRMT6.

Results. The analysis revealed an association between SHBG SNP candidate genes and a BC risk in patients with luminal A/B subtypes and lacked significant associations between the loci assessed and triple negative BC subtype. CC female genotype of rs10454142 PPP1R21 increased a risk of luminal A/B subtypes BC by more than 2-fold (recessive model [CC vs. TC+TT]; odds ratio = 2.07; 95 % confidence interval = 1.14–3.77; p = 0.017; pperm = 0.018). This SNP is localized in functionally "significant" regions of the genome (enhancers/active enhancers, promoters/active promoters) and affects methylation level in several hepatocyte DNA sites [cg15846641 (chr2:48541264)].

Conclusion. The genetic variant rs10454142 PPP1R21 is associated with the risk of developing ВС luminal A/B subtypes, but not with ВС triple negative subtype.

Published: November 2023

This study aims to report the epidemiological characterization, incidence, mortality and prognostic factors of tuberculosis in indigenous patients of Paraguay from 2018 to 2022. A retrospective cohort study was carried out with data extracted from the National Tuberculosis Program from January 2018 to June 2022. The clinical records of 1659 indigenous patients were included in the study. The indigenous population with tuberculosis in the period 2018-2022 was between 0 and 20 years old (25.4%), mostly female (54.6%), residing in Presidente Hayes (22.4%), and was from the rural area (74.3%), of the Mbya ethnic group (20.4%). The diagnosis was bacteriological in 69.2%, 96.1% had pulmonary location, 94.5% of the study population started treatment and 1.1% presented drug-resistance, while 88.3% corresponded to new cases. The highest number of new cases of tuberculosis in indigenous people was 336 in 2019. The incidence of tuberculosis was associated with age and area of residence, being more incident in the youngest and in the Presidente Hayes area. A total of 11.2% died, and the highest number of deaths occurred in 2019 with 47 cases (14%). We observed that the elderly, who did not start treatment, and who were coinfected with HIV were more likely to die from tuberculosis. The number of new cases and mortality from tuberculosis is high in the Paraguayan indigenous population. Age and coinfection with HIV continue to be risk factors for mortality.

Published: November 2023

Background: Aging, low literacy, and vascular risk factors are agents to boost or maintain the numbers, with more and more elevated costs for informal caregivers and society. Widely public health priority recognition implies changes and challenges in some European countries involving political engagement, needs that in dementia care are unmet. A preliminary diagnosis of the gaps and a prioritization of strategies to be implemented in Portugal should be addressed. The World Health Organization framework for meaningful engagement could work, as it has already done for other chronic diseases to reach some of the goals to improve healthcare. Methods: A review of the current situation and some of the initiatives delivered through healthcare professionals with recognized experience in dementia areas and patients’ associations, in a South Europe country over the last few years. In view of the remaining gaps, proposals from the literature will be provided to improve care experiences. Conclusion: We defend that is essential that Portugal deepen patient-centered care, integrated care pathways, and equal access for rural or marginalized populations to specialist assessment for an early diagnosis. Improving the quality of dementia care in care homes or managing a dementia care program to link resources for patients and caregivers, are key themes that need proactive preparation for the coming years. We present 8 recommendations for dementia care in Portugal.

The publication deals with the issue of ensuring the stability of an unmanned aerial vehicle flight by speed. An analysis of the physical essence of the process of ensuring the unmanned aerial vehicle stability by speed is presented. Attention is paid to the flight modes in which the operator (external pilot) may encounter difficulties in the practical piloting of the unmanned aerial vehicle.
The possible causes of abnormal situations when flying the unmanned aerial vehicle at speeds close to the borderline low are analyzed. Possible actions of the operator (external pilot) to return the unmanned aerial vehicle to the operating speed range from the area of instability are considered.
The article shows the features of stability and controllability of an unmanned aerial vehicle in a route flight mode. Attention is paid to the complexity of piloting and safety of flight in the second modes. The article demonstrates the method of determining the boundary between the first and second flight modes. The features of unmanned aerial vehicle management and ensuring stability in the first and second modes are shown.
The issue of dynamic stability of the unmanned aerial vehicle is investigated. Numerical modeling of the longitudinal movement of the unmanned aerial vehicle in free, uncontrolled flight was carried out, trajectories for the unmanned aerial vehicle of the selected configuration with a change in speed and angle of inclination of the trajectory in time were obtained. Graphs of movement trajectories with changes in speed and height over time were constructed, graphs of transient processes were constructed for cases of stable and unstable flight modes. An analysis of the external factors that most affect the flight parameters in various conditions of unmanned aerial vehicle use was carried out.
MODELING OF INTELIGENT SOFTWARE FOR THE DIAGNOSIS AND MONITORING OF SHIP POWER PLANT COMPONENTS USING MARKOV CHAINS
Authors: Sharko Oleksandr , Yanenko Artem
Published: November 2023

The reliability and serviceability of metal structures depends on the quality of control over the technical condition and mechanical properties of materials in accordance with international standards. However, in the course of operation, deviations from the normative values of material properties occur due to the uncertain nature and magnitude of the loads, which necessitates periodic shutdowns of the equipment for the purpose of diagnostics. Uninterrupted operation of elements of power equipment of marine vessels depends on the quality of control of their technical condition by physical diagnostic methods. The most effective method of reducing operating costs and increasing the reliability of equipment is maintenance based on interactive monitoring of its condition, detection of malfunctions and forecasting of energy equipment parameters. This makes the tasks of control, diagnosis and forecasting of energy equipment parameters particularly relevant. At the same time, the use of various diagnostic methods does not allow taking into account all the features of real operating conditions. This problem is especially acute in conditions of various extreme situations and peak loads, which cannot be taken into account. Probabilistic methods, in particular Markov chains, are a promising area of research. The system of intelligent diagnostics and monitoring of ship power plant turbochargers using Markov chains is presented. The novelty of the developed methodology lies in replacing discrete time intervals of the diagnostic process with a sequence of states of technical objects. In this formulation, Markov chains represent a synthetic property that accumulates diverse factors. Randomization of stochastic diagnostic and monitoring processes of ship power plant components enables an increase in reliability of equipment under severe operating conditions. The results of calculations of digitalization of experimental data, calculations of transition matrices and construction of an orgraph allowing to study the kinetics of damage accumulation in real time are presented.

Authors: Amir Mohd. , Singh Neetu , Upadhyay Rupa
Published: November 2023

Background: The role of soil solarization in suppression of soil borne pathogens and weeds has been established by several researchers around the globe It involves capturing solar radiations when the soil receives the maximum sunlight in May-June using a polythene mulch. Its effectiveness depends on ambient temperature, duration of the treatments and soil moisture. This not only acts as a soil disinfectant but also as soil decontamination. It includes various changes in the soil like physical, chemical and biological properties. Methods: The field to lab and vice-versal based investigations were carried during 2021-2022 at Amity Centre for Biocontrol and Plant Disease Management, Amity University, Uttar Pradesh, Noida and identified tomato nurseries of district G B Nagar where heavy infestation (10-12 J2/cc soil) of root knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood was recorded. The treatments comprised of sustainable components viz. deoiled seed cake of neem, a Arbuscular Mycorrhizal fungus Glomus intraradices and indigenous fungal strain of Trichoderma harzianum, (Th7) alone and together applied for evolving IPM module at solarized and unsolarized sets. Under microplot trials, the entire solarized treatments were carried out measuring 3 × 1 sq. meter each in which one set of all the treatments including control covered with clear transparent polythene sheet (400 ì gauge) for solarization. The treatments were replicated thrice in randomized block design. Result: The observations of solarized and unsolarized treatments clearly revealed that the soil solarization in treatments where the sun radiant energy was trapped by 400 µ transparent polysheets significantly reduced the root knot nematode Meloidogyne incognita population both in root and soil in comparison to unsolarized treatments where no solar energy trapping was done. The combined application of locally isolated Trichoderma harzianum (Th7) and VA mycorrhiza, Glomus intraredices enhanced germination and plant growth in nurseries. In the present investigation, the solarized IPM module- 4 comprising of other sustainable components viz. neem oil-seed cake, T. harzianum (Th-7) and Arbuscular Mycorrhizal (AM) fungus G. intraredices is proved to be an ideal one in root-knot nematode pest management in tomato nurseries.

Authors: Padhy Chitrasena , Reddy M. Devender , Raj Rabindra Kumar
Published: November 2023

Background: The cotton cultivation in India is influenced by high inputs and expenditure. But the farmers do not get sufficient access to institutional credit; hence the farmers borrow money at the higher interest from other sources. Higher risks due to the impacts of climate change furtherincrease the economic burden and uncertainty of getting reasonable income to the farmers. Furthermore, the crop suffers due to incidence of pests and diseases. Because of this situation, farmers encounter risks and pressures, yet they seldom openly reveal the psychological strain that accompanies their agricultural work. Hence, the current study was carried to identify strategies to be adopted by cotton growers to manage risk and stress in crop management, agricultural extension and input arrangement. Methods: The study was conducted by collecting information from 240 cotton growers of four blocks in Gajapati and Rayagada districts of Odisha. The opinion on socio-psychological, technological competency and input supply strategies to be adopted was collected individually through a semi-structured schedule and analyzed. Result: The opinion of cotton growing farmers on the strategies to be adopted in minimizing the risks and stresses in cotton production on socio-psychological, technological competency and input supply showed that the farmers preferred to have participatory decision on cluster approach, developing good drainage facility and advance supply of inputs and materials, periodical visits by extension officials’ to the farmers’ field and create awareness on latest varieties availablewith high yield and training on latest technologies and ensuring quality and timely input supply, providing information on market price and immediate payment for their produce.

Published: November 2023

This study discusses the Fuzzy Elimination Et Choix Traduisant La Realite (ELECTRE) method that can be applied to make a decision support. This method was chosen because it is one of the methods used to rank and determine the best alternative. This study aims to determine the results of the application of the fuzzy ELECTRE method which produces alternative solutions in determining employee performance appraisal ratings for the Education and Culture Office of Malang City. Some of the problems that often occur in employee performance evaluation at the Department of Education and Culture in the city of Malang are still ineffective and inaccurate because the calculation process is still manual. Based on this, the effort to reduce the problems above is to implement a Fuzzy Multi Attribute Decision Making decision support system with the fuzzy ELECTRE method. This method requires a process of normalizing the decision matrix (X) into a comparable scale, then weighting the normalized matrix, then determining the concordance and discordance indices for each alternative pair to calculate the concordance and discordance indices, the ranking process is used to choose the best alternative. This study is limited by several criteria used as linguistic variables with the Triangular Fuzzy Number scale, including SKP scores, service orientation, integrity, commitment, discipline, and cooperation. Based on employee performance appraisal data that has been calculated using the fuzzy ELECTRE method, the best alternative that occupies the top rank with the highest value is alternative 2 with a value of 55.9155. It is hoped that by using the fuzzy ELECTRE method, the ranking process can be more precise in identifying employees who will become outstanding employees.

Fuzzy Multi Criteria Decision Making (FMCDM) method is a method of making decisions based on certain criteria to determine the best alternative among several alternatives.  The purpose of the FMCDM method is to obtain the best alternative that is accurate and optimal. Poverty is a condition in which economic needs are not met against the average standard of living in the region. Poverty is a very important issue for the government or related agencies. This problem can be solved by determining the district/city area which is included in the poor category. So a method is needed that can be used to determine the existence of poverty in an area. The solution to overcome this problem is to use the FMCDM method. The solution to overcome this problem is to use the FMCDM method. The FMCDM process begins by determining objectives, alternative decisions, and a collection of criteria that will be used to determine poor districts/cities in East Java Province. The alternative decisions consist of 38 regencies/cities of East Java Province, while the set of criteria consists of the Percentage of Poor People, Human Development Index, Poverty Depth Index, and Poverty Severity Index. The next step evaluates the fuzzy set by aggregating the weight of the criteria and the degree of fit of each alternative to its criteria. The aggregation result is called the fuzzy match index which consists of three values, namely, the  value which represents the result of the lower limit aggregation, the  value which represents the middle bound, and the  value which represents the upper bound value. The three values are ranked using the ranking method for fuzzy numbers with degrees of optimasan. So that the total integral value for each alternative will be a decision from the highest priority to the lowest in determining the districts / cities included in the poor category and as an effort to reduce poverty in East Java Province.

Published: November 2023

Cet article analyse la dynamique des mutuelles d’assistance funéraire et de leur impact socioéconomique dans les espaces urbains en Côte d’Ivoire. En effet, Bouaké, à l’instar de certaines villes ivoiriennes s’illustre dans ces dernières années par un nombre croissant de mutuelles d’assistance funéraire. Ce travail de recherche a adopté les méthodes quantitatives et qualitatives. À cet effet, les entretiens et les questionnaires menés respectivement auprès des responsables des différentes structures et des mutualistes révèlent que dans les différentes mutuelles interrogées à Bouaké, de 2008 à 2022, le nombre total d’adhérents est passé de 1734 à 36642. Par ailleurs, le nombre de mutuelles d’assistance funéraire sur la même période est passé de 7 à 14. Aussi, les montants des assistances sont-ils passés de 100.000 F CFA à 1.000.000 F CFA par mutualiste. En somme, l’on constate une multiplication des adhésions dans l’ensemble de ces mutuelles enquêtées. Cet engouement autour de ces mutuelles s’explique par plusieurs raisons, entre autres, la spontanéité et l’importance des prestations financières consistantes. Ces mannes financières sont dans l’ensemble, réinvesties dans des activités génératrices de revenus ou l’immobilier.

 

This article analyzes the dynamics of funeral assistance mutuals and their socio-economic impact in urban spaces in Côte d'Ivoire.  Indeed, Bouaké, like some Ivorian towns, has distinguished itself in recent years by a growing number of mutual funeral assistance funds.  This research work adopted both quantitative and qualitative methods.  To this end, the interviews and questionnaires conducted respectively with the heads of the various structures and the mutualists reveal that in the various mutuals questioned in Bouaké, from 2008 to 2022, the total number of members increased from 1,734 to 36,642., the number of mutuals of funeral assistance over the same period rose from 7 to 14. Also, the amounts of assistance increased from 100,000 CFA francs to 1,000,000 CFA francs per mutualist.  In short, there is an increase in membership in all of the mutuals surveyed.  This enthusiasm for these mutuals can be explained by several reasons, among others, the spontaneity and the importance of consistent financial services. These financial windfalls are generally reinvested in income-generating activities or real estate.

Purpose ― The main objective of this study is to develop a comprehensive digital financial inclusion index (CDFII) that accounts for technology-driven financial inclusion and to compare it with a traditional financial inclusion index (TFII) to enhance the measurement of fintech-driven financial inclusion across countries.Methods ― The study employs a three-stage principal component analysis (PCA) to construct the CDFII and TFII using the latest available data from 31 developing countries during the period 2015-2021. The CDFII incorporates a new sub-index measuring individual literacy levels for using financial services, along with existing sub-indices capturing the penetration, availability, and usage of DFS. By integrating digital financial inclusion (DFII) and TFII, the overall CDFII is estimated.Findings ― The findings reveal that the levels of DFII and CDFII are higher than TFII for most of the economies examined. This indicates the significant impact of technology-driven financial inclusion in expanding access to formal banking and non-banking financial services for previously unbanked populations.Implication ― The study implies that policymakers and researchers should prioritize the integration of technology-driven financial inclusion indicators, such as the comprehensive digital financial inclusion index (CDFII), into their assessments and interventions to ensure a more accurate and effective approach to promoting inclusive and sustainable economic development.Originality ― This study introduces the CDFII as a novel comprehensive index that addresses the shortcomings of traditional financial inclusion indices. By incorporating individual skill levels and considering dimensions specific to DFS, the CDFII provides a more accurate representation of fintech-driven financial inclusion levels. This contributes to the existing literature on financial inclusion measurement and provides a valuable analytical tool for researchers and policymakers.
Exact Similarity Solutions of Unsteady Laminar Boundary Layer Flows
Authors: Sun Bohua
Published: November 2023

The studies of laminar unsteady boundary layer flows is crucial for understanding laminar-turbulence transition and origins of turbulence. However, the task of finding its solutions poses a significant challenge. In this paper, we propose a novel approach by introducing a similar transformation to convert the 2D unsteady laminar boundary layer equations into a single partial differential equation. By applying this transformation, we are able to obtain the "exact" similarity solutions for the 2D unsteady laminar boundary layer equations, specifically for the case of flat plate boundary flow. Notably, this is the first time that such an exact solution has been obtained. Application of this exact solution is being used to solve Stokes' first problem in 2D boundary layer. Perspectives on the transition fron Rayleigh solution to Blasius solution is provided.

Several factors, such as internal algorithm, sensor technology, and obsolescence might skew outcomes when comparing different gas analysers measurements during CPET. Besides aerosol borne infectious disease are a source of contamination during cardiopulmonary exercise tests (CPET). Thus, the main aim of this study was to determine the agreement degree between the Quark RMR and the Jaeger Oxycon Pro, using an antibacterial filter with the latter. Forty-two participants (19-54 years old) performed two non-consecutive maximal graded exercise tests on a cycle-ergometer on two counterbalance and different days using the Oxycon Pro and the Quark RMR in a randomized order. Differences between devices were tested using a generalized linear model adjusted by Bonferroni, and correlation and agreement was assessed using Pearson’s correlation coefficient (R), intraclass coefficient correlation (ICC), Lin’s concordance correlation coefficient (CCC) and Bland-Altman plots. No significant differences were found between devices in any of metabolic or ventilatory parameters for cardiorespiratory fitness assessment (VO2max: 3131.3±882.1 vs. 3189.8±894.8, p=0.071, VCO2max: 3436.3±936.0 vs. 3550.3±1043.2, p=0.071, for Quark RMR and Oxycon Pro, respectively). However, Bland-Altman plots showed a trivial tendency towards Oxycon Pro overestimation relative to Quark RMR as air flow volume increases. Both devices showed strong correlation and high level of agreement during maximal and submaximal exercise intensities (Pearson’s R: 0.974 & 0.977; ICC: 0.985 & 0.987; Lin’s CCC: 0.971 & 0.974, for VO2 and VCO2, respectively). Therefore, providing consistency to CPET data comparison between both devices, and insight into whether the use of these metabolic carts could be interchangeable or combined when a single device cannot be used for CPET assessment.

Acid in-situ leaching (ISL) is a common approach to the recovery of uranium in the subsurface. As some toxic and harmful substances might be produced by the chemical reactions among the injected sulphuric acid, the groundwater, and the porous media during leaching processes, the pollution control of the mining plan for ISL is important. In this study, a three-dimensional reactive transport modeling (3DRTM) was applied to decide the pollution control mining plan, considering the partial penetration through wellbore in confined aquifer and complex chemical reactions between main minerals. Based on the 3DRTM, different pumping ratio and non-uniform injection schemes were compared. The results show that the preferential pollution control mining plan is non-uniform injection ratio equal 0.1. By analyzing the characteristics of water table and streamline, it is concluded that the scheme has a strong hydraulic capture effect. In this scheme, the concentration of UO22+, H+, SO42- obtained by 3DRTM is lower. The inner well injection rate is 194.09 m3/d, the outer well injection rate is 158.89 m3/d, and the pumping rate is 264.00 m3/d. A reasonable suggestion is to adopt non-uniform injection mining mode in ISL.
Evaluation of In Vitro and Anti-inflammatory Activity of Products Containing a Breath Mask and Filter Based on Polyurethane and Polyvinylidene Fluoride Nanofibers

Published: November 2023

Nanofiber (NF) products exhibit outstanding performances in the materials science, textile, and medical fields, which cannot be realized using conventional technologies. However, the safety of such products is debated because of the potential risk of nanomaterials and lack of standardized guidelines for safely evaluating NF products. The global safety evaluations of nanomaterials focused on evaluating the cytotoxicity of zero-dimensional materials including nanoparticles and nanotubes based on OECD criteria. The NFs are one-dimensional materials with nanometer diameters and considerable lengths. Many fibers are applied in a densely woven web-like form, and therefore, assessing cellular penetration and fiber toxicity using the same methods is inappropriate. This study verifies the safety of polyurethane (PU) and polyvinylidene fluoride (PVDF) polymers, which are currently applied in filters and masks. To this end, polymer NFs were collected from each product, and the NFs were compared with reference samples considering their physical properties using FT-IR and Raman spectroscopy. For the safety evaluation, DMSO stocks of varying concentrations of PVDF and PU NFs (at 0.5, 1, 5, and 10 μg/mL) were prepared, and the cytotoxicity and inhibitory effects on nitric oxide production and protein expression obtained via Western blot were identified.

The conducted investigation encompassed the comprehensive integration of mechanical, envi-ronmental, chemical, and microstructural evaluations of a composite amalgamating sandy soil and a synthetic polymer at two distinct concentrations (2.5% and %) across multiple curing in-tervals (0, 1, 2, 4, 7, 15, 30, and 45 days). The studied soil originates from an environmentally sig-nificant protected area in Brazil. The implementation of mechanisms for soil improvement in the region must adhere to technical criteria without causing environmental harm. Direct shear testing was conducted, permeability was assessed, and microstructure analysis and XRD and XRF/EDX studies of both the soil and composites were conducted. It was observed that longer curing times yielded improved results in shear stress, friction angle, and cohesive intercept, with SP_5% exhibiting the highest values compared to the soil and SP_2.5%. Adding the polymeric so-lution to the soil contributed to cementation and cohesion gains in the substrate. Through mi-crostructural characterization, the polymer's role as a cementing agent for the grains is evident, forming a film on the grains and binding them together. Based on the analyses and studies con-ducted in the research, it can be concluded that there is technical feasibility for applying the pol-ymeric solution at both dosages in geotechnical projects.

Spray technology is widely used in various industries, including medicine, food production, mechanical engineering, and nanopowder manufacturing. Achieving high dispersion and a narrow particle size distribution is crucial for many applications. Ultrasonic spraying is commonly used to achieve this. On other hand, hydraulic nozzles provide high atomization performance. Combining these two technologies promises to offer significant benefits, but the complex processes that occur simultaneously in such a device require careful study. This work proposes a fundamental design for an acoustic-hydraulic nozzle and investigates the physical processes when a liquid is sprayed using this nozzle, both theoretically and experimentally. The study identifies the critical modes of spraying and confirms that the simultaneous use of ultrasound and hydraulic pressure can produce a fine spray (droplet size less than 50 μm) with high productivity (5-10 ml/s). This approach has significant potential for modern industries and technologies.
