Authors: Paprotny Zbigniew
Published: September 2022

The paper sets out to attempt identification of all known plates used to print maps included in theAtlas Silesiaeand of all identified states of these maps. While the early states of theAtlasmaps are relatively well studied (though far not in every detail), printings pulled from the same though deeply reworked plates, published in Nurnberg in the first two decades of the 19thc., are not always recognised as the late states of the same maps. For each of twenty maps fromAtlas Silesiaelisted are all identified states together with the most distinctive differences between them. Eleven copies ofAtlas Silesiaewere also examined in search for possible regularities of their composition in terms of states of the included maps. Public collections with exemplary copies of theAtlasmaps in each state identified in the paper are listed in the Appendix.

Authors: Albatayneh Aiman
Published: September 2022

Jordan and many countries unfortunately have no up-to-date reliable data on the share of electrical energy consumption by end-use in its residential buildings. Therefore, to determine the share in Jordan’s middle district, detailed data was completed for around 350 buildings. The participants in this survey were engineering students in their final year of an energy auditing course in the German Jordanian University. The data were used to determine the primary share of electrical energy end-use in residential buildings. These data, the first of their kind in Jordan, were recorded by trained participants and are essential for the adoption of appropriate future energy efficiency programs in Jordan. These shares of electrical energy consumption by end use in residential buildings in Jordan are the first of their kind it is necessary to ensure adequate planning for future energy efficiency programs in Jordan and this will enable policymakers to support certain technologies and implement large-scale energy efficiency programs in the residential sector.

Published: September 2022

Background: The incidence and mortality of pulmonary tuberculosis (PTB) are rising globally in the coronavirus disease (COVID-19) era due to resource allocation and the deviation of global attention toward the pandemic. Hence, this study aimed to assess and evaluate the current knowledge and attitude toward PTB among the residents in Riyadh.
Methods: A cross-sectional study was conducted among Riyadh residents using a self-administered online questionnaire. The sample size was calculated as 385. A scoring system was developed to categorize the level of knowledge of PTB into poor, good, and excellent. The questionnaire also evaluated the attitude level.
Results: Out of 759 participants, the male-female ratio was almost equal, and nearly 80% had a university education level. The participants' scores were 31%, 39%, and 30% for poor, good, and excellent knowledge regarding PTB, respectively. There were significant statistical associations between the score (p = 0.012), the ability to identify PTB signs and symptoms (p = 0.002), and age; and also between the level of education and PTB knowledge (p = 0.03).
Conclusion: The overall level of knowledge was good, which could be attributed to age, level of education, and COVID-19 awareness campaigns. There was a lack of knowledge in essential PTB information with an insufficient attitude toward PTB patients. The public needs more positive enforcement and awareness of the disease's basic concepts. Further studies on less-educated groups and older adults are needed for better assessment.

Published: September 2022

Cijeruk known as a strategic location that is still very close to the Mount Salak area, but also close to the urban area of Bogor itself. This causes the area to have the potential to have good water absorption, but it also has the potential to be disturbed by water absorption due to internal and external factors in the research area. For this reason, it is necessary to know the water absorption and infiltration rate in order to see the advanced conditions of the research area. In order to know this, researchers need to obtain primary data by processing in the field using a Double Ring Infiltrometer (Indonesian National Standard, 7752:2012); while secondary data were obtained from previous researchers, as well as official bodies in Indonesia. The rainfall at the nearest Citeko station per 5 years reaches more than 3000mm, namely 3168.8mm, indicating that the research area has a very high potential for rainfall. In addition, it can be concluded that the research area has a type of overburden in the form of loamy sand with flat to steep areas in 4 observation locations, while the other 5 observation locations are flat to very steep. Then, the results obtained in the Cijeruk area obtained 2 units of infiltration rate, namely sufficient infiltration rate with an infiltration rate of 0.192 m/day to 0.312 m/day and a high infiltration rate with an infiltration rate of 1.08 m/day up to 5.04 m/day. indicates that the water catchment area is classified as good.

The Common Research Model with natural laminar flow (CRM-NLF) shows promising numerical and experimental results. This work aims at understanding the aerodynamic characteristics of the CRM-NLF wing under wind-tunnel conditions. The significant effects of turbulent wedges and static aeroelastic deformation are shown. Fluid–structure coupled simulations including laminar–turbulent transition with turbulent wedges show an improved agreement with wind-tunnel data made available by NASA when both effects are considered.
Uncertainty Inclusive Runway Balancing Using Convolutional Neural Network
Authors: Mori Ryota , Dalahaye Daniel
Published: September 2022

This paper proposes a new optimization scheme using neural networks for runway balancing to minimize departure and arrival aircraft delay. The delay prediction for runway balancing optimization is obtained by a neural network, only without any additional simulations. Developing an accurate simulation model under an uncertain environment is difficult, but the proposed neural network model can estimate the average delay without modeling uncertainty explicitly. In this paper, the effectiveness of the proposed method is validated through numerical simulations. First, simulations are used to generate the data, which are then used to train the neural network. Next, the runway balancing problem is solved via simulated annealing using the delay predicted by the neural network. The simulation result shows that the proposed approach outperforms the simulation-based method under an uncertainty environment. Therefore, the neural network is shown to accurately estimate the delay under the uncertainty environment, which makes the proposed neural-network-based method applicable to objective function calculations for optimization.
Convolution/Volterra Reduced-Order Modeling for Nonlinear Aeroelastic Limit Cycle Oscillation Analysis and Control
Authors: Brown Cameron , McGowan Greg , Cooley Kilian , Deese Joe , Josey Tim , Dowell Earl H. , Thomas Jeffrey P.
Published: September 2022

A methodology for leveraging a combination of linear (through convolution integrals) and nonlinear (through Volterra series) reduced-order modeling (ROM) development was demonstrated on both a two- and three-degree-of-freedom (2-DOF and 3-DOF, respectively) aeroelastic system. The linear/nonlinear ROM approach was demonstrated against previous work in the field for a 2-DOF system and subsequently extended to a 3-DOF (flapped airfoil) system. Excellent agreement was demonstrated at limit cycle oscillation (LCO) onset (flutter) prediction between computational fluid dynamics, linear ROMs, and nonlinear ROMs. Although linear ROMs were sufficient to predict LCO onset, the nonlinear Volterra correction was required to estimate the amplitude of post-LCOs. Corrections that accounted for more coupling between degrees of freedom predicted the amplitudes more accurately. A study was undertaken to determine the minimal training set required to produce reasonable LCO amplitude estimates of the 3-DOF airfoil. A controller was also implemented in an effort to mitigate LCO onset and flutter divergence and to demonstrate the usefulness and power of leveraging the ROM for control design. A full-state feedback controller, tuned via a linear quadratic regulator (LQR), was shown to be effective in controlling the system below LCO onset. However, beyond LCO onset, this specific linear controller structure was observed to be ineffective in controlling the system. Future work will evaluate nonlinear control methods in which the ROM can be deployed as a part of the control system to update the LQR gains in a fully coupled approach.

Order Versus Disorder in 1,2,3- and 1,2,6- Trimethylpyridinium Chlorocuprate(II) Salts
Authors: Al-Mashala Habeeb , MacAinsh Brendan , Bond Marcus
Published: September 2022

The vicinal trimethypyridinium (TMP) cations with 1,2,3- or 1,2,6- substitution form distinct compounds when crystallized from aqueous solution. (1,2,6-TMP)2CuCl4 forms asdark green crystals, in which the 1,2,6-TMP cation is ordered, that exhibit a thermochromic transition to a yellow phase above 60 degrees C. (1,2,3-TMP)CuCl3(H2O) forms as emerald green crystals, in which the 1,2,3-TMP cations are two-fold disordered by symmetry, that are non-thermochromic. In order to study the effect of disorder on the choice of compound, a successful attempt was made to prepare mixed cation crystals by slow evaporation of a solution containing a 1:1:1 ratio of 1,2,3-tmP:1,2,6-TMP:CuCl2. Dark green crystals with the characteristic color of the CuCl4 dianion compound were the only ones obtained. Structure determination on on of these crystals verified the presence of the CuCl4 dianion, but now with a mix of 1,2,3-TMP and !,2,6-TMP with occupancies of 0.85 and 0.15 respectively. Thus it appears that a small reduction of the positional disorder of the 1,2,3-TMP cation favors formation of the CuCl4 compound over the CuCl3(H2O) compound. Further, the presence of disorder now in the CuCl4 compound appears to stabilize the low temperature phase. Observation of thermal response of several different crystal to increasing temperature found the transition temperature dramatically higher than in pure (1,2,6-TMP)2CuCl4 or completely absent. The variation of thermal response by different crystal suggest the mixed cation crystals form as a solid solution rather than as a compound with a defined composition. These results suggest several different directions for future work.

SWIR dyes offer many advantages over their more common NIR congeners; however, the available options are limited. New SWIR imaging agents can be accessed by remodeling existing NIR molecules (i.e., hemicyanines (HD)). In this study, we syn-thesized SWIR-HD, a modified HD featuring silicon-dimethyl and benzo[cd]indolium groups that are designed to red-shift the absorbance and emission to 988 and 1126 nm, respectively. SWIR-HD was tested in three cell lines and shown to exhibit ex-cellent biocompatibility.

Authors: Olatayo Olahanmi , Ogunniyi Sunday , Olaluwoye Oladimeji
Published: September 2022

A major problem retarding the commercialization of biodiesel is the derivation of catalysts and feedstock from high-cost materials. Hence, in order to mitigate such challenge, the following objective is being put forward: to extract and characterize castor oil, synthesize and characterize cocoa pod ash as the base catalyst before and after use, and apply the base catalyst for biodiesel production. The cocoa pods were thermally treated at 600 ℃ for 35 minutes in a muffle furnace, then it was sieved to obtain ash that is uniform in size distribution. The yield of castor oil extracted was 42 %. Also, the catalyst synthesized was found to possess good features that are capable of transesterifying the extracted oil. Afterward, the castor oil was used for the production of biodiesel with the aid of cocoa pod ash as a catalyst under the reaction conditions, 88 % yield of biodiesel was obtained. Characterization methods such as XRD, SEM, and FTIR were performed on the catalyst to confirm the presence of the active sites. The physico-chemical properties of the castor oil produced are consistent with literature values.
BODIPY-labelled estrogens for fluorescence analysis of environmental microbial degradation
Authors: Felion Celeste , Lopez-Gonzalez Ricardo , Sewell Alan L. , Marquez Rodolfo , Gauchotte-Lindsay Caroline
Published: September 2022

Biodegradation of estrogen hormone micropollutants is a well-established approach towards their remediation. Fluorescently labelled substrates are used extensively for rapid, near real-time analysis of biological processes and are a potential tool for studying biodegradation processes faster and more efficiently than conventional approaches. However, it is important to understand how the fluorescently tagged surrogates compare with the natural substrate in terms of chemical analysis and the intended application. We derivatized three natural estrogens with BODIPY fluorophores by azide-alkyne cycloaddition click reaction and developed an analytical workflow based on simple liquid-liquid extraction and HPLC-PDA analysis. The developed methods allow for concurrent analysis of both fluorescent and natural estrogens with comparable recovery, accuracy, and precision. We then evaluated the use of BODIPY-labelled estrogens as surrogate substrates for studying biodegradation using a model bacterium for estrogen metabolism. The developed analytical methods were successfully employed to compare the biological transformation of 17β-estradiol (E2), with and without BODIPY fluorescent tag. Through measuring the complete degradation of E2 and the transformation of BODIPY-estradiol to BODIPY-estrone in the presence of a co-substrate, we found that BODIPY-labelled estrogens are biologically viable surrogates for investigating biodegradation in environmental bacteria.

Published: September 2022

Over the past few years, high external quantum efficiencies (EQE) have been achieved for blue, green, red, and near infrared perovskite light-emitting diodes (PeLEDs), and their energy efficiencies are approaching the efficiencies of III-V based LEDs. Beyond the visible regime, ultraviolet light offers great promise for many applications such as disinfection, which has become increasingly important since the COVID-19 pandemic. However, PeLEDs demonstrate poor performance in the violet/ultraviolet region, with reports of violet PeLED performance hindered by poor thin film quality. In this work, we improve the uniformity of perovskite film by adding water into the precursor solution to engineer the crystallization process of spin-coated 2D perovskite. The PeLEDs deliver bright violet emission at 408 nm, with a maximum external quantum efficiency of 0.41%, a fivefold increase over control devices. This work demonstrates viable steps towards cost-effective, efficient ultraviolet PeLEDs.
A Sulfoxide Reagent for One-Pot, Three-Component Syntheses of Sulfoxides and Sulfinamides
Authors: Saito Fumito
Published: September 2022

Sulfoxides and sulfinamides represent versatile sulfur functional groups found in ligands, chiral auxiliaries, and bioactive molecules. However, canonical two-component syntheses relying on substrates with a preinstalled C–S bond impede efficient and modular access to these sulfur motifs. Herein is presented the application of an easily prepared, bench stable sulfoxide reagent for one-pot, three-component syntheses of sulfoxides and sulfinamides. The sulfoxide reagent donates the SO unit upon the reaction with a Grignard reagent (RMgX) as a sulfenate anion (RSO–). While subsequent trapping reactions of this key intermediate with carbon electrophiles provide sulfoxides, a range of tertiary, secondary, and primary sulfinamides can be prepared by substitution reactions with electrophilic amines. The syntheses of sulfinamide analogs of amide- and sulfonamide-containing drugs illustrate the utility of the method for the rapid preparation of medicinally relevant molecules.
Particle Size and Pore Size Selection on Ordered Mesoporous Silica
Authors: Li Tianyu
Published: September 2022

Achieving particle size control and pore size control is crucial when utilizing mesoporous silica to perform fundamental studies. Pore size can be controlled by adjusting the reaction condition during the synthesis of mesoporous silica. Here Realizing that different sizes of particles fall at different speeds in the liquid, we achieve a narrow particle size selection through the sediment of the mesoporous silica in water. By applying particle size selection on mesoporous silica with different pore sizes, silica particles with the exact pore sizes but different particle sizes, or with varying sizes of pore but exact particle sizes are obtained.
In silico design of dihydroazulene/vinylheptafulvene photoswitches for solar-energy storage guided by an all-around performance descriptor
Authors: Arpa Enrique M. , Durbeej Bo
Published: September 2022

The possibility to use the reversible cycling of molecular photoswitches between isomeric forms as a means to store and release solar energy has stimulated the development of candidate systems based on several different core structures, such as the dihydroazulene/vinylheptafulvene (DHA/VHF) couple. However, a major challenge in these efforts is to simultaneously realize many of the performance criteria required of the switches for such applications. Here, we take on this challenge by first introducing an all-around performance descriptor that combines three key criteria (related to energy density, storage time and light-absorption characteristics), and by then using density functional theory (DFT) methods to calculate its values for 52 newly designed DHA/VHF switches. Through this approach, we are able to identify several switches with excellent overall properties that contain a structural motif absent in all DHA/VHF compounds considered for solar-energy storage in the existing literature. For some of these switches, we also provide retrosynthetic analyses for their preparation and perform DFT calculations to demonstrate that they form the energy-storing VHF isomer through a facile DHA  VHF photoisomerization reaction. All in all, we conclude that these switches show great promise for further development towards applications in solar-energy storage.
WS22 database: combining Wigner Sampling and geometry interpolation towards configurationally diverse molecular datasets
Authors: Pinheiro Jr Max , Zhang Shuang , O. Dral Pavlo , Barbatti Mario
Published: September 2022

Multidimensional surfaces of quantum chemical properties such as potential energies and dipole moments are common targets for machine learning, requiring the development of robust and diverse databases extensively exploring molecular configurational spaces. Here we composed the WS22 database covering several quantum mechanical (QM) properties (including potential energies, forces, dipole moments, polarizabilities, HOMO, and LUMO energies) for ten flexible organic molecules of increasing complexity and with up to 22 atoms. This database consists of 1.18~million equilibrium and non-equilibrium geometries carefully sampled from Wigner distributions centered at different equilibrium conformations (either at the ground or excited electronic states) and further augmented with interpolated structures. The diversity of our data sets is demonstrated by visualizing the geometries distribution with dimensionality reduction as well as via comparison of statistical features of the QM properties with those available in existing data sets. Our sampling targets broader quantum mechanical distribution of the configurational space than provided by commonly used sampling through classical molecular dynamics, upping the challenge for machine learning models.
Pathways to Statelessness and Parent-Child Separation among Uyghurs in Turkey
Authors: Melanson Marie-Ève
Published: September 2022

This article explores the self-reported experiences of Uyghur migrants in Turkey regarding the pathways that lead to statelessness and parent-child separation. First, I discuss statelessness among Uyghurs, including Uyghur children, living in Turkey. Second, I address the issue of parent-child separation during migration and resettlement, and the resulting “orphanhood” of Uyghur children. Finally, I turn to the role that Uyghur-led educational initiatives play in addressing Uyghur refugee children’s needs specifically, and the current crisis in the Uyghur homeland more generally. This paper contributes to the scholarship on refugee law and resettlement by exploring the ways in which the crisis in the Uyghur homeland has impacted and continues
The Cartography of Focus and Interrogative Projections in Ǹjò-Kóo
Authors:   Adekunle Ajasin University, Nigeria, S. Olaogun
Published: September 2022

Researches on cartography have made universal predictions on the hierarchies of functional projections in language. Based on this assumption, the structural maps established by Rizzi (1997, 2001b) for the left-peripheral elements suggest very strongly that Interrogative dominates Focus. Nevertheless, a straight-jacket adoption of this proposed hierarchical order to account for these left-peripheral projections in Ǹjò-Kóo would be counterintuitive. Therefore, leaning on empirical and theoretical evidence, the paper calls to question the universality of the cartographers’ claim, and argues that the opposite of the view is true of Ǹjò-Kóo. The paper adopts fieldwork method for data elicitation and descriptive approach as well as minimalist program for analysis of data. Data used in this study were elicited from purposively selected native speakers based on language proficiency. Data were acquired with syntactic checklist and structured interviews, and were subjected to interlinear and qualitative analysis.
An Optimality Theoretic Analysis of the Mid Tone in Isekírì
Authors:   University of Benin, Nigeria, O.R. Osewa , Evbuomwan O.O. ,   University of Benin, Nigeria
Published: September 2022

The asymmetric behaviour of the mid tone has been reported in the Yoruboid literature and previous accounts of tone behaviour in Iṣẹkírì suggest that a low tone is always deleted in favour of others at word boundary. However, synchronic data have shown that this is not the case. This paper investigates tonal asymmetry and the non-participation of the mid tone in some phonological processes in Iṣẹkírì. The study adopts an Optimality Theory (OT) version that incorporates the grounding conditions to develop constraints of implicational statements into faithfulness constraints. Data are elicited from eight speakers of the language, recordings are with the aid of a digital audio device and the tool used for our acoustic measurement is Praat 6.0.30. The analysis reveals that tonal asymmetry in this language always deletes the Mid-tone at word boundary and not the Low tone, also noting that the Low tone may be deleted in some cases. The lack of participation of the M tone in some phonological processes such as vowel elision, glide formation and vowel assimilation reveals the unstable nature of this tone in Iṣẹkírì.

Authors: Ali Raza
Published: September 2022

Cloud computing is one of the latest and greatest environments for delivering Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS) in digital communications infrastructure. Cloud computing helps the user remotely access the required service as needed through the Internet. But this technological advancement, due to its remote availability in the cloud, leads to new attacks. One of the biggest threats to cloud infrastructure is Distributed Denial of Service (DDoS) flooding attacks. DDoS flooding attacks are clearly trying to exploit the availability of services for a legitimate user. An attacker gains access to a large number of computers (i.e., botnets) by exploiting the vulnerabilities, and then uses the botnets to initiate an organized attack with a large number of targets. This paper analyses the latest methods for detecting and preventing Distributed Denial of Service (DDoS) attacks. It also provided methods and technologies for preventing, detecting, and responding to DDoS flood attacks.

Cloud computing plays a vital role in education, politics, religion, transportation, relationships, medical check-ups, and so on. In education, online courses are carried out with the help of cloud computing. In cloud computing, expert conversations and classes delivered through any electronic device are protected on the server. The user can collect any information from the server through any search engine. There are so many platforms for downloading information for users. Electronic devices are very popular in this digital world. Some companies or individuals are introducing many applications for mobile phones and computers. One of the most useful options is search engines. It is very common to collect existing information on a server and it is a good communicator between users and cloud computing systems. Prospective teachers are the future teachers who will shape future citizens. The aim of the paper is to raise awareness of cloud computing among prospective teachers. This paper used a survey method to determine cloud computing awareness among prospective teachers and includes 61 samples from the College of Education. It uses the Cloud Computing Awareness Checklist tool to collect data for the present study. Hypotheses related to family type, locality, father's profession, father's education, and parents' income were found to have no significant differences. Thus, the result showed that prospective teachers have little knowledge of cloud computing. The researcher concluded that background variables are not significant. The essential things are the funds provided and the desire to learn. This will develop awareness and finally, the educator and prospective teachers raise awareness among prospective teachers and students, respectively. Educators encourage future teachers to collect more information about cloud computing on its own or with the help of an external facilitator.
Interactive Forms Of Light

Published: September 2022

In the last few decades, computational technologies have arisen in architectural design. These technologies could create a new area of research that engages with design cognition, computation, and generative principles. To fully understand the potential of computer-aided architectural design, research should be carried out on the possibilities of implementing these technologies into a modern form of architectural expression.

To evaluate this, I must first understand the computational design strategies of interactive, kinetic, and biomimetic architecture. I will also consider climate-responsive buildings that enhance a building’s spatial and functional qualities. This is relevant as architecture moves towards energy-efficient design. I will also consider how materiality and lighting impact the integrity of these designs. I will then take these research areas and discuss possible opportunities for development.

Moving into my own work, I have sought to incorporate elements of biomimetic design in combination with climate-responsive conditions for a built form in the Coromandel Peninsula. During summer, the high number of visitors to the area makes it an ideal location for a small-scale architectural proposal. The warm climate and stunning natural surroundings also make it a desirable area for temporary accommodation. The proposed design will mimic local flora, creating an external kinetic structure that moves in accordance with sunlight. This will camouflage and conceal the built form from its natural surroundings and utilise sunlight for the maximum utility of its occupants.

How can these computational technologies become visually striking and an integral part of the design itself? How can they change how a building functions and feels? The work completed in this thesis represents a possible integration between computational literature and kinetic design concepts. This may shed light on how we think about representing architecture in the future.

Published: September 2022

This paper presents an analysis of various designs of transformable membrane reflector antennas for spacecrafts, considers the dependence of the surface accuracy on the operating frequency of the antenna and the requirements imposed on deviations of the antenna surface from the paraboloid. A classification of membrane transformable antennas is presented depending on the presence or absence of supporting elements and stiffeners. Structural schemes for opening membrane antennas are described, from the classical umbrella opening scheme to original schemes for winding ribs on a central hub, tension supporting elements, winding paraboloid segments on a central hub, and folding the reflector surface using origami methods. The design of an offset membrane transformable antenna is considered. Modern materials for the manufacture of reflectors of membrane antennas, such as polymer composite materials with triaxial weaving of carbon fabric with a silicone matrix, polyamide and polyimide films with and without reinforcement, are considered. Materials with shape memory for opening membrane antennas are considered. Calculations of structures for natural vibration frequencies, calculations for bending of folds are described. A description of ground-based experimental testing, in particular, for the disclosure of various types of membrane antennas, was carried out.

El escultismo es un movimiento lúdico-social que permite formar a niños y jóvenes en los valores preponderantes de una sociedad. El objetivo de esta investigación es identificar las características socioculturales y emocionales de los niños y jóvenes que ingresan y permanecen en un grupo scout de la ciudad de Bogotá. Metodológicamente la investigación se abordó desde una perspectiva cuantitativa, transversal, descriptiva. Se utilizaron dos instrumentos, el primero es la encuesta TMMS-24 (Trait-Meta Mood Scale), que permite determinar la inteligencia emocional de los participantes; el segundo es un instrumento creado por los autores que determina aspectos socioculturales de la población a estudiar. Como hallazgo principal, se pudo evidenciar la importancia de los padres y/o familiares cercanos en el proceso de formación y apoyo que se le brindan a niños y jóvenes. Se muestra determinante el compromiso de los padres en la decisión del niño o joven de permanecer en el grupo.

Abstract. Allergic rhinitis (AR) is one of the most urgent problems of allergology and immunology, since, despite the improvement in diagnostic and treatment approaches, the number of patients suffering from allergic diseases of the respiratory tract remains very significant. AR is a common allergic disease of the upper respiratory tract in children living in the Moscow, Yaroslavl, Tver, Vologda and Vladimir regions, with a frequency of occurrence in 2021 from 1.472% to 2.684% (mean random effect 2.143 with CI: 1.599-2.763). There is an annual increase in patients with AR in each region, but at the same time, the heterogeneity of the samples allows us to state that in each specific region, the increase in AR occurs under the influence of various risk factors specific to a particular region, ignorance of which leads to an increase in the total number of patients with AR, the number children with late diagnoses, as well as a decrease in the quality of life of patients and their families, which has significant socio-economic consequences. At present, as far as we know, there have been no works devoted to a one-time analysis of statistical data on the assessment of the prevalence and incidence of AR in a multicenter study in Russia.

Abstract. The distribution of plant species containing at least one individual chemical compound with an experimentally established antibacterial effect in sets of plant species usedin traditional medicine in bacterial diseases is considered. Compounds are grouped. 9 groups of compounds (flavonoids, terpenoids, quinones, alkaloids, phenols, coumarins, lactones, iridoids, xanthones) and 37 diseases (pulmonary tuberculosis, dysentery, scrofula, pneumonia, tonsillitis, purulent wounds, abscesses, syphilis, nephritis, cystitis, laryngitis, whooping cough, gonorrhea, erysipelas, anthrax, leprosy, diphtheria, scarlet fever, pharyngitis, skin tuberculosis, sepsis, urethritis, gangrene, cholera, bone tuberculosis, typhus, pyelonephritis, typhoid fever, tuberculosis of the lymph nodes, pyelitis, lung abscess, meningitis, tetanus, brucellosis, plague, infectious-allergic polyarthritis, tuberculosis of the throat) were taken into account. To analyze the distribution, Student's mathematical-statistical test was used. It was noted that in the sets of plant species used for these diseases, in most cases, the occurrence of plant species containing antibacterial compounds from more than one of the groups under consideration was significantly increased.
