PRESSURE AND VELOCITY VARIATION IN REMOTE-CONTROLLED PLANE USING CFD ANALYSIS
Authors: Velidi Gurunadh
Published: September 2022

Aircraft are significant because they transport people and commodities through a wide range of terrains in a short amount of time. Newton's third law states that thrust is created by fly motors due to the response powers provided by fume gases. In this paper, computational fluid dynamics (CFD) analysis of an aeroplane is used to create an ideal design. Prior to the time-consuming production of aircraft, qualitative and quantitative wing characterisation gives important information for verifying wing choices and design. Each wing was independently subjected to CFD study at various velocities. Each wing's lift, drag, pressure, and velocity were measured, and a comparison analysis revealed how little adjustments to the wing's pressure, drag, velocity lift may have a significant impact. Each wing's lift, drag, pressure, and velocity were measured, and a comparison analysis revealed how small adjustments to the wing's overall flow characteristics improved the overall flow characteristics.
DESIGN OF AN AIRFOIL BY MATHEMATICAL MODELLING USING DATABASE
Authors: Anastasiia Novokhatska
Published: September 2022

The aerodynamic performance of low Reynolds airfoils with a Reynolds number less than 105 is critical for a variety of applications, including unmanned aerial vehicles, micro air vehicles, and low-speed/high-altitude aircraft. In general, most airfoils with Reynolds numbers less than 106 cannot be considered to have constant lift and drag characteristics. XFLR5 is a tool for analysing low-Reynolds-number airfoils, wings, and aircraft. It comes with XFOIL's direct and inverse analysis tools. The lifting line theory, the vortex lattice approach, and the 3-D panel method are all used to build and analyse wings. The lift coefficient (Cl) and pressure distribution (Cp) are fundamental metrics that determine the behaviour of airfoils. The cornerstone of aerodynamic analysis during aircraft development is pressure distribution data.
DETECTION OF STRUCTURAL CRACKS OF AN AIRCRAFT USING DEEP NEURAL NETWORKS
Authors: Aleksandr G. NETKACHEV
Published: September 2022

Thanks to developments in machine learning (ML), particularly deep learning, which now has the greatest performance among algorithms, narrow artificial intelligence, often known as "weak AI," has progressed during the past few years. further machine learning for deep learning to provide potent model parameters that can forecast the occurrence of certain events in the future, massive volumes of data, also referred to as "big data” and must be rapidly collected. Such a big damage event dataset is not accessible in many other fields, such as visual inspection of aeroplanes, and this makes it difficult to train deep learning algorithms to work effectively. Good at spotting physical damage to aircraft structures. In order to reach this human-level intelligence in aircraft damage inspection, it is possible to include inductive bias into deep learning. This paper provides an illustration of how to incorporate expertise in aircraft engineering into the creation of deep learning algorithms. The effectiveness of our method, which builds a deep convolutional neural network that categorises crack lengths based on break propagation curves acquired from fatigue testing, was shown on aerospace grade aluminium samples.
LIFT AND DRAG FORCE PREDICTION USING CONVOLUTIONAL NEURAL NETWORKS
Authors: Obaid Ahmed J.
Published: September 2022

The adaptability of the convolutional neural network (CNN) technique is probed for aerodynamic meta- modeling task. The primary objective is to develop a suitable architecture for variable flow conditions and object geometry, in addition to identifying a sufficient data preparation process. Multiple CNN structures were trained to learn the lift coefficients of the airfoils with a variety of shapes in multiple flow Mach numbers, Reynolds numbers, and diverse angles of attack. This was conducted to illustrate the concept of the methodology. Multi-layered perceptron (MLP) solutions were also obtained and compared with the CNN results. The newly proposed meta-modeling concept has been found to be comparable with the MLP in learning capability; and more importantly, our CNN model exhibits a competitive prediction accuracy with minimal constraints in geometric representation.
PITCH MOVEMENT AND ANALYSIS OF AIRCRAFT USING OPENVSP
Authors: Sajaratuddur  , Hilda Lelya
Published: September 2022

There are many different design options available thanks to the growing number of customised solutions in the aircraft design process, which mostly rely on new technology at the component level. In addition, there is a rising need for a uniform, intelligible data model due to the process' increased complexity as well as the increasing number of possible fixed-wing aircraft configurations. Design is made simpler by the use of parametric geometry tools like Vehicle Sketch Pad (OpenVSP), which express geometry in language that are most familiar to designers. The development of new OpenVSP features and capabilities has been extensively covered in publications and presentations over the years, but use case studies and best practises are frequently not documented. To illustrate the use of OpenVSP in the design process, this paper provides examples of advanced OpenVSP templates best practises.
RECOGNITION OF AIRCRAFT IN REMOTE SENSING IMAGES USING CONVOLUTIONAL NEURAL NETWORK
Authors: Sahith Jai Krishna
Published: September 2022

Picture processing is a stand-alone, non-human image comprehension system that is one of the major breakthroughs (IUS). When one tries to explain what comprehension is, the effort of comprehending images becomes massive. In addition to classical signal processing, pattern recognition and artificial intelligence are applied. The early phases of the picture comprehension process might be called scene analysis methods that use edge and texture segmentation. As a result, putting a man in a signal processing loop at particular sensors, such as remotely piloted vehicles, satellites, and spacecraft, is not acceptable. Smart sensors and semi- automated procedures are being created as a result. Another major use of image processing is land remote sensing. With the debut of shows like Star Wars, this application has taken on a new level of relevance in the military's eyes. This study gives an overview of digital image processing and investigates the reach of remote sensing and IUS technology from the military's perspective. To demonstrate the significance of IUSs, a detailed description of a current autonomous car project in the United States is provided.
DESIGN AND STEADY STATE THERMAL ANALYSIS OF AIRCRAFT FUSELAGE
Authors: Kabir Muhammad Ashraful
Published: September 2022

Commercial aeroplanes conducting domestic flights in the US have an average age of 10.7 years, and this number is rising. The employment of robots and imaging technology in fuselage inspections has the potential to save costs, speed up the process, and raise inspection quality. The subject of several discussions and studies nowadays is power supply systems. Researchers look for answers in renewable natural or alternative resources for power supply because of the poor ecological state of many industrialised countries. There are still no affordable, mobile energy delivery methods. It is difficult to move the power factory quickly and safely to distant locations. Aircraft are the quickest mode of transportation, but how long can they fly before needing to refuel? Due to the increased requirement for aeronautical technology brought on by flights, the scientific and technical communities are also looking for answers in the area of energy supply. The main objective of contemporary integrated ecological systems is to address the issues of powering during flight and supply the extra power to other purposes. The steady state thermal analysis of an aeroplane fuselage and its application are covered in this work.

Authors: M. Bader Amjed , I Esraa K. , AL-Jawaheri A.A.M , O. Saba A.
Published: September 2022

Seawater has been used to immerse metals in several industrial applications. Axial loading is applied to these alloys. These alloys are prone to corrosion failures due to differences in environmental conditions. This research looked at the influence of submerged corrosion on the buckling behaviour of 304 stainless steel long column type and intermediate alloy under increasing compressive dynamic stresses. Compressive buckling experiments were performed on twenty-four 304 stainless steel alloy columns, twelve of which were non-corroded, and the tests were performed under increasing axial dynamical compression loads. Before testing, the remaining columns were submerged for 90 days. For the subterranean columns, a maximum decrease of percent in critical buckling loading was obtained. This work uses the Rankine, and Perry-Robertson formulas to calculate the critical buckling stress of non-corroded and corroded 304 stainless steel alloys. The theoretical conclusions of the critical buckling stress were in good accord with experimental data

Redefine Coaching & Athlete Development in Sports
Authors: Waddington Lee
Published: September 2022

Redefine Coaching & Athlete Development in Sports is the first book to combine academic research, professional experience, and applied practice to redefine the way in which sports coaching is delivered and how athletes are developed. Written by Lee Waddington, a leader in the field of soccer coaching—learning content creation and delivery—and currently a practicing coach, this book clearly and concisely introduces the academic evidence for how the Framework to Freedom system can be applied to practice, both on and off the field.

The Framework to Freedom system focuses on the child as a whole rather than playing abilities only. It examines four key areas: coaching, care, connectivity, and consumption. Using sport as the cornerstone, the system develops each individual child through a unique coaching program that uses a game-based approach underpinned by the science of learning.

Outlined in the chapters are current issues within sports coaching—such as blocked practice, individual rather than team development, and the 10,000-hour myth—as well as creative solutions for these issues. These solutions are supported by academic research from several disciplines such as neuroscience, sports science, and psychology.

Through its clear structure, the book allows coaches and parents the opportunity to gain a genuine understanding of the science of learning that underpins the Framework to Freedom system and the unique way in which they can deliver practice to support each individual athlete. The book is an essential resource for any sports coach, parent, or student wishing to develop a new way of using evidence-based theory and methodology to create practices that develop strong athletes and outstanding individuals.

Low Rates of Lung and Colorectal Cancer Screening Uptake Among a Safety-net Emergency Department Population
Authors: Pettit Nicholas , Ceppa DuyKhanh , Monahan Patrick
Published: September 2022

Introduction: A suspected diagnosis of cancer through an emergency department (ED) visit is associated with poor clinical outcomes. The purpose of this study was to explore the rate at which ED patients attend cancer screenings for lung, colorectal (CRC), and breast cancers based on national guidelines set forth by the United States Preventive Services Task Force (USPSTF).

Methods: This was a prospective cohort study. Patients were randomly approached in the Eskenazi Hospital ED between August 2019–February 2020 and were surveyed to determine whether they would be eligible and had attended lung, CRC, and breast cancer screenings, as well as their awareness of lung cancer screening with low-dose computed tomography (LDCT). Patients who were English-speaking and ≥18 years old, and who were not critically ill or intoxicated or being seen for acute decompensated psychiatric illness were offered enrollment. Enrolled subjects were surveyed to determine eligibility for lung, colorectal, and breast cancer screenings based on guidelines set by the USPSTF. No cancer screenings were actually done during the ED visit.

Results: A total of 500 patients were enrolled in this study. More participants were female (54.4%), and a majority were Black (53.0%). Most participants had both insurance (80.2%) and access to primary care (62.8%). Among the entire cohort, 63.0% identified as smokers, and 62.2% (140/225) of the 50- to 80-year-old participants qualified for lung cancer screening. No patients were screened for lung cancer in this cohort (0/225). Only 0.6% (3/500) were aware that LDCT was the preferred method for screening. Based on pack years, 35.5% (32/90) of the patients who were 40-49 years old and 6.7% (6/90) of those 30–39 years old would eventually qualify for screening. Regarding CRC screening, 43.6% (218/500) of the entire cohort was eligible. However, of those patients only 54% (118/218) had been screened. Comparatively, 77.7% (87/112) of the eligible females had been screened for breast cancer, but only 54.5% (61/112) had been screened in the prior two years.

Conclusion: Many ED patients are not screened for lung/colorectal/breast cancers even though many are eligible and have reported access to primary care. This study demonstrates an opportunity and a need to address cancer screening in the ED.
COVID-19 and Serious Bacterial Infection in Febrile Infants Less Than 60 Days Old
Authors: Guernsey David , Pfeffer Matthew , Kimpo James , Vazquez Hector , Zerzan Jessica
Published: September 2022

Introduction: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to the coronavirus disease 2019 (COVID-19) pandemic that drastically impacted the United States. The evidence was not clear on how SARS-CoV-2 infection impacted children, given the high prevalence of SAR-CoV-2 infection. Febrile infants less than 60 days old are an ongoing challenge to risk-stratify for serious bacterial infection (SBI), including urinary tract infection (UTI), bacteremia, and meningitis. We hypothesized there would be a lower rate of SBI in SARS-CoV-2 positive febrile infants compared to those SARS-CoV-2 negative.

Methods: This was a retrospective chart review with a nested, age-matched, case-control study performed from March 2020–June 2021. Infants less than 60 days old presenting with fever were assigned groups based on SARS-CoV-2 infection. Blood, urine, and cerebrospinal fluid cultures were used as the gold standard to diagnose SBI. We compared overall rate of SBI as well as individual rates of SBI between each group. We performed a subgroup analysis evaluating the age group 29-60 days old.

Results: A total of 164 subjects met criteria for analysis: 30 COVID-19 positive and 134 COVID-19 negative subjects. Rate of SBI was 17.9% (95% confidence interval [CI]: 11.8-25.5%) in the COVID-19 negative group compared to 0% (95% CI: 0.0%-11.1%) in the COVID-19 group, which demonstrated statistical significance (p = 0.008). In the age-matched data, we found statistical significance for any SBI (p = <0.001). For individual rates of SBI, we found statistical significance for UTI (p = <0.001) and bacteremia (p = <0.001). The 29- 60 days-old subgroup analysis did not achieve statistical significance (p = 0.11).

Conclusion: This study demonstrated the utility of including SARS-CoV-2 infection as part of the risk stratification of febrile infants less than 60 days old. While overall there is a low incidence of bacteremia and meningitis in this age group, these results can contribute to existing literature and potentially help decrease invasive testing and exposure to broad-spectrum antibiotics.

Published: September 2022

Introduction: Patients with tIPH (used here to refer to traumatic intraparenchymal hemorrhagic contusion) or intraparenchymal hemorrhage face high rates of mortality and persistent functional deficits. Prior studies have found an association between blood pressure variability (BPV) and neurologic outcomes in patients with spontaneous IPH. Our study investigated the association between BPV and discharge destination (a proxy for functional outcome) in patients with tIPH.

Methods: We retrospectively reviewed the charts of patients admitted to a Level I trauma center for ≥ 24 hours with tIPH. We examined variability in hourly BP measurements over the first 24 hours of hospitalization. Our outcome of interest was discharge destination (home vs facility). We performed 1:1 propensity score matching and multivariate regressions to identify demographic and clinical factors predictive of discharge home.

Results: We included 354 patients; 91 were discharged home and 263 to a location other than home. The mean age was 56 (SD 21), 260 (73%) were male, 22 (6%) were on anticoagulation, and 54 (15%) on antiplatelet therapy. Our propensity-matched cohorts included 76 patients who were discharged home and 76 who were discharged to a location other than home. One measure of BPV (successive variation in systolic BP) was identified as an independent predictor of discharge location in our propensity-matched cohorts (odds ratio 0.89, 95% confidence interval 0.8-0.98; P = 0.02). Our model demonstrated good goodness of fit (P-value for Hosmer-Lemeshow test = 0.88) and very good discriminatory capability (AUROC = 0.81). High Glasgow Coma Scale score at 24 hours and treatment with fresh frozen plasma were also associated with discharge home.

Conclusion: Our study suggests that increased BPV is associated with lower rates of discharge home after initial hospitalization among patients with tIPH. Additional research is needed to evaluate the impact of BP control on patient outcomes.
Emergency Services Capacity of a Rural Community in Guatemala
Authors: Hughes Matthew , Schmidt Jessica , Svenson James
Published: September 2022

Introduction: Access to emergency care is an essential part of the health system. Improving access to emergency services in low- and middle-income countries (LMIC) decreases mortality and reduces global disparities; however, few studies have assessed emergency services resources in LMICs. To guide future improvements in care, we performed a comprehensive assessment of the emergency services capacity of a rural community in Guatemala serving a mostly indigenous population.

Methods: We performed an exhaustively sampled cross-sectional survey of all healthcare facilities providing urgent and emergent care in the four largest cities surrounding Lake Atitlán using the Emergency Services Resource Assessment Tool (ESRAT).

Results: Of 17 identified facilities, 16 agreed to participate and were surveyed: nine private hospitals; four public clinics; and three public hospitals, including the region’s public departmental hospital. All facilities provided emergency services 24/7, and a dedicated emergency unit was available at 67% of hospitals and 75% of clinics. A dedicated physician was present in the emergency unit during the day at 67% of hospitals and 75% of clinics. Hospitals had a significantly higher percentage of available equipment compared to clinics (85% vs 54%, mean difference 31%; 95% confidence interval (CI) 23-37%; P = 0.004). There was no difference in availability of laboratory tests between public and private hospitals or between cities. Private hospitals had access to a significantly higher percentage of medications compared to clinics (56% vs 27%, mean difference 29%; 95% CI 9-49%; P = 0.024).

Conclusion: We found a high availability of emergency services and universal availability of personal protective equipment but a severe shortage of critical medications in clinics, and widespread shortage of pediatric equipment.

Severe, Progressive Meningoencephalitis in a Patient with Coexisting SARS-CoV-2 and Cytomegalovirus Infection: A Case Report
Authors: Alavi-Moghaddam Mostafa , Pirzade Moghaddam Nadia , Tajabadi Zohreh
Published: September 2022

: SARS-CoV-2, the pathogen responsible for COVID-19, has infected hundreds of millions since its emergence in late December 2019. Recently, concern has been raised due to the increased prevalence of co-infections with opportunistic pathogens among these patients. Though not common, co-infections may be associated with adverse outcomes and increased risk of morbidity and mortality among patients suffering from COVID-19. Cytomegalovirus (CMV) infection is a serious problem among immunocompromised and critically ill patients. So far, few cases of co-infection with COVID-19 and CMV have been reported. Here, we report the co-infection with COVID-19 and CMV in a young woman presenting with sudden, progressive fever, delusion, agitation, bizarre behavior, seizure, and loss of consciousness leading to death despite receiving appropriate anti-viral treatment. To the best of our knowledge, this is the first case of coexisting SARS-CoV-2 and CMV infection presenting with severe, progressive meningoencephalitis in the era of COVID-19.

Background: The application of methylprednisolone in ARDS patients has led to a sustained reduction in inflammatory plasma cytokines and chemokines and has recently been used in the treatment of patients with SARS-CoV-2 infection. Objectives: In this study, the effect of methylprednisolone on clinical symptoms and antioxidant changes of patients with COVID-19 has been investigated. Methods: In the present study, patients with moderate to severe COVID-19 who required hospitalization were entered into the study phase. Then, in addition to standard treatment, patients received methylprednisolone at a dose of 250 mg intravenously over three days. Necessary evaluations include analysis of arterial blood gases, pulse oximetry, monitoring of patient clinical signs, examination of inflammatory biomarkers, and also receiving 10 cc of peripheral blood samples to check for antioxidant changes, at the beginning of the study, after 24 hours, and 72 hours after receiving methylprednisolone was on the agenda. Results: Changes in fever, superoxide dismutase (SOD, Glutathione-S-Transferase (GST, the ferric reducing ability of plasma (FRAP, malondialdehyde (MDA, Nitric oxide, Ferritin, and TNF-α before treatment and 72 hours after treatment were significantly different between the two stages (P < 0.05). Conclusions: The use of methylprednisolone improves the balance of antioxidants and immunological factors in patients with COVID-19 and thus improves some clinical indicators in these patients.

: The number of reports of the extrapulmonary manifestations of the coronavirus disease 2019 (COVID-19) is increasing in the literature. The neurological manifestations of COVID-19 in pediatric patients, however, are not well studied. Acute transverse myelitis is among the neurological manifestations usually reported with viral infections. However, the development of transverse myelitis in pediatric patients following COVID-19 is extremely rare. We report a case of acute transverse myelitis in a previously healthy 11 years old female patient with COVID-19 who was asymptomatic before the onset of weakness.

Oral Product Development, Pharmaceutical Technology & Development, Operations, AstraZeneca, Macclesfield, UKEmail: zhc906@student.bham.ac.ukIntroductionA tablet consists of the active pharmaceutical ingredients (API), and the other components, excipients. A tablet needs to withstand coating, packing and shipping stresses whilst maintaining the dissolution time; therefore, the tensile strength is of great importance. Currently, there is a lack of understanding on why excipients improve the bulk powder properties and the bonding mechanisms of the powder during compression. This makes tablet formulation development an inefficient trial-and-error process that is required for every new API (1). Literature has shown that the surface energy of the powders contributes a significant amount towards the tablet tensile strength. Hydrophobic powders have a lower surface energy (2) and are seen to disrupt this tablet strength (3,4).Experimental Aim and MethodThe aim was to investigate the impact of the hydrophobicity of excipient powders on tabletability of microcrystalline cellulose. This was done by mixing powders of varying hydrophobicity with MCC at varying mass fractions. There was focus on a lower mass fraction (0.02-0.1 m/m) with increasing increments of 0.02 m/m of added additive as well as gaining a global picture (0.2-1 m/m) with increments of 0.2 m/m.ResultsIt was found that at low mass fractions (0.02-0.4 m/m) of additive added the hydrophobic powders disrupted the tablet strength more compared to hydrophilic powders which could be attributed to the levels of surface energy of the additive. In contrast, at higher mass fractions (0.6-0.8 m/m), the surface energy is not as important and it is hypothesised that the deformation mechanisms of the additives governs the tablet strength.1.

The subject of the research in the framework of the article is the international and national practice of regulation and implementation of activities in the field of tourism in the Central Ecological zone of the Baikal Natural Territory. As part of the analysis of the impact of tourism activities on the ecosystem of the World Heritage site "Lake Baikal", based on the materials of the authorities, conclusions are formulated about the possibility of deterioration of the ecological state of Lake Baikal and the emergence of social tension in the event of an increase in the number of tourists on its shores. The content of guidelines on the organization of tourism at UNESCO World Heritage sites is disclosed, the most successful international practices of tourism management are correlated with the implementation of regional programs for the development and organization of sustainable tourism. The conclusion is formulated about the importance of collecting information about the tourist infrastructure, statistical data. The program documents defining the policy in the field of tourism in the Central ecological zone of the Baikal Natural Territory are analyzed, the conclusion is made that there is no unified strategy for the development of Baikal as a World Heritage site. The factor of significant influence and participation of the local population in the implementation of tourist activities is noted, the need for the involvement of the local population in the planning of tourist activities is indicated. The analysis of the Global Code of Ethics of Tourism, the Framework Convention on the Ethics of Tourism. The main content of the Global Initiative to Reduce Plastic Consumption in Tourism and recommendations for improving procurement activities in the tourism sector are revealed. The problem of compliance with moral and ethical requirements by subjects of relations in the field of tourism is noted as one of the underestimated problems. The study resulted in recommendations both on the modernization of the existing domestic regulatory framework and the development of new documents in the field of sustainable tourism.
The Mythology of Time in Modern Foreign period dramas: between Retrotopia and Metamodern Sensibility
Authors: Linchenko Andrei Aleksandrovich
Published: September 2022

. The purpose of this article is to analyze the specifics of the mythologizing of time in the historical period dramas "Downton Abbey" and "The Crown" in the context of the transition from the postmodern paradigm to a new metamodern sensibility. The article summarizes the experience of domestic and foreign studies of the metamodern tendencies of the modern TV series and analyzes the theoretical issues of the mythological temporality of TV series production. On the basis of the theoretical concept of retrotopia by Z. Bauman, the concept of layers of cinematic temporality by N.E. Marievskaya and the critical discourse analysis of S. Jäger, the features of the mythologization of horizontal, vertical time, as well as the biographical time of characters in selected period dramas have been analyzed. The scientific novelty of the article lies in the problematization and analysis of the discursive environment of the deployment of the temporal mythology of the modern period drama. The modern historical period drama demonstrates the specifics of turning to retrotopia, as it seeks to represent the current problems of the present through an imaginary past. In the case of the “Downton Abbey”, this happens through the harmonization in the viewer's mind of nostalgia for an imaginary English aristocratic past and an unstable future. In the case of the “The Crown”, the presentation of the private life of the British royal family against the backdrop of historical events contributes to the formation of a more multidimensional image of the present and responds to the demands of the mass audience in the emotional representation of historical events. The result of this representation is a kind of mythology of time, which arises between the cultural demand for retrotopia and the development of modern technologies for the production of cinematographic products, which makes it possible to fully realize the intention of modern metamodernist discourse to achieve a “new sensibility”. This allows us to consider the modern historical period drama not only as a "commercial project", but also as a tool for the development of historical culture, an instrument of cultural orientation in social space and time.
The Muslim Population of Ufa. Analysis and Visualization of the Data of the "Religious Census" of the NKVD in 1923
Authors: Iunusova Aislu Bilalovna
Published: September 2022

The subject of the analysis is the materials of the 1923 census of Muslim religious organizations in Ufa, compiled by the author into database «Muslims of Ufa according to the 1923 NKVD census». The issues of socio-territorial localization of the Muslim population are considered in the context of the functioning of a religious parish as an element of the urban structure. NKVD census (1923) testifies the territorial distribution of Ufa Muslims in accordance with the social characteristics of the parishioners, the most distinctive of which are class affiliation, type of labor activity, knowledge of the Russian language. Muslim parishes of the 1920 differ from modern ones. The former socio-territorial confessional organization turned into an ethno-confessional association without territorial boundaries and social homogeneity. Main conclusions: 1) the materials of the «religious census» of the NKVD (1923) have a high information potential for historical, socio-anthropological, religious studies; 2) 1923 data fixed social homogeneity of Muslim parishes in Ufa. A hundred years ago, the urban parish was the same organizational unit of the Muslim population as the rural one, uniting Muslims of a certain territory, social status, types of work, lifestyle, language of communication; 3) the materials of the «religious census» of the NKVD are important as a source for studying the social topography of the city, the history of religious organizations. The results of the analysis can be used in the study of ethno-confessional processes, in the teaching of history.
