10. Quantifying Spatial Structure of the Largest Regional Centersin Russia: General Patterns and Typological Features

Author

Saveleva, E. O.

Abstract

Abstract: The quantitative analysis of urban form has long become an important component of both academic research and practice contributing to a better understanding of how cities function and evolve. Despite the abundance of studies quantifying urban structures of the cities in developed countries, the reach of modern quantitative methods into studying the urban form of the Russian cities has been limited. This paper aims to fill in the knowledge gap of the quantified urban form characteristics of the largest regional centers in Russia presenting a GIS-based multivariate analysis of the similarities and differences between their urban structures. The results of the spatial modelling form the base for the development of the typology of urban structures produced via the k-means statistical clustering technique. Attributing the city to one of the three types of urban form identified—compact, discrete, or extended—allows obtaining a better understanding of the city’s spatial organisation that should in turn feed into the grounded strategy for its development.

Abstract

The features of fission fragments formed in the near barrier reaction 32 S + 197 Au ( E beam lab = 166 MeV ) are investigated. The measurement was performed at the ALTO facility of IPN Orsay, France, with the aim of clarifying the quantitative contribution of the quasi-fission process to the total fission events. The mass and total kinetic energy of the fission fragments were compared to the expectations of the liquid drop model, revealing an asymmetric fission component which may be traced back to a quasi-fission process mixed with the fusion–fission events. The γ -rays and neutrons measured in coincidence with the fission fragments were used to yield additional information for the discrimination of the two aforementioned mechanisms. All observed trends are consistent and fairly well reproduced by the statistical model. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: The Ear, Throat and Nose Pathology and hearing loss is a major problem in children case, as it can be the cause of mental and speech underdevelopment A child with hearing loss has difficulties adapting to society and at school Plus breathing and nasal disorder causes hypoxia, which leads to increasing problems in education Every age group has different hearing impairment With newborns and toddlers it is mainly sensorineural Pre-school and school age is characterized by a wider list of factors leading to hearing loss Acute and chronic diseases of ENT organs, especially during the cold seasons in Russia, can also cause hearing loss. Objective: To determine the prevalence of ENT organ pathology and hearing impairment among primary schoolage children in the autumn-spring seasons in two regions of Russia: Ufa and Novosibirsk. Methods: We evaluated 429 primary school-age children in Ufa and 216 from Novosibirsk A total of 645 schoolchildren (1 290 ears) were examined All of them were between 7 to 11 years old Classical examination ENT organs with otoscopy, tonal threshold audiometry, tympanometry, TE OAE was performed. Results: In 849 ears (65.8%) the middle ear pathology was not detected and the otoscopy, tympanometry, tonal threshold audiometry corresponded to a healthy ear The TE OAE was registered Still the TE OAE was not registed in 441 ears (34.2%) In these cases different abnormalities were found Otoscopic results in this group of children were: inflow eardrum (64 ears), immobility or stiffness of the eardrum (286 ears), exudate in the tympanic cavity (72 ears), 'air bubbles' (19 ears), adhesion or petrification of the tympanic membrane (23 ears) and persistent perforation (19 ears) The degree of hearing loss was assessed in accordance with the International classification: weak degree (26--40 dB), moderate (41--55 dB), moderate severity (56--70 dB, severe (71--90 dB) and deafness (more than 90 dB) The results of the tonal threshold audiometry found a unilateral hearing impairment in 67 children, binaural -- in 35 schoolchildren Often (264 ears) we observed an increase in the hearing threshold at one or more frequencies from 10 to 30 dB Hearing loss 1st, 2nd or 3rd degrees was detected in 137 ears Sensoneural hearing loss (SHL) was detected in 19 ears, conductive (CHL) in 87 ears, mixed (MHL) in 31 ears Two children had unilateral deafness The most often problems were revealed during ENT examination: acute infectious rhinitis and sinusitis (67 children), allergic rhinitis (23 children), chronic tonsillitis (34 children), hypertrophy of the adenoids (36 children) and other abnormalities (pathology of the nasal septum, vasomotor rhinitis, chronic sinusitis) Tympanometry showed that in 26.0% of cases, dysfunction of auditory tubes was detected (tympanogram type C) In 11.2% of cases, we observed exudative otitis with tympanogram type B We found that in 65% of cases, auditory tube dysfunction and exudative otitis were combined with various problems of the nasal cavity and nasopharynx. Conclusions: The data of the examination of schoolchildren show that the most common cause of hearing loss of primary school pupils is the pathology of the middle ear with conductive hearing loss Therefore, tympanometry is the most useful test that allows you to identify problems of the middle ear at an early stage We want to underline what the use of tonal threshold audiometry and TE OAE in the school is difficult due to the noise of the premises and the need for a soundproof cabin It is very important that none of the children actively complained about hearing loss or ear problems As a result parents were also not aware of the children's ear problems Teachers, on the other hand, often noted.

Abstract

International audience; The overlap in the mass symmetric region of the reaction products from fusion-fission and quasi-fission complicates the assignment of symmetric events to complete fusion on the basis of the mass distribution alone. Additional observables, besides mass distribution, should be used. The method proposed here relies on the fact that fusion-fission and quasifission are characterized by a different timescale. Within this framework we performed a detailed study to find out if timescales can be probed via angular momentum as measured via γ rays multiplicity. The proof of principle was carried out by measuring the γ rays in coincidence with two fragments in the reaction 32S + 197Au at beam energy near the Coulomb barrier. The experiment has been performed at the Tandem ALTO facility at IPN Orsay using a detection setup consisting of ORGAM and PARIS γ detector arrays coupled with the CORSET time-of-flight spectrometer. Preliminary results on the sensitivity of this method to distinguish reaction channels with different dynamics are discusses.

Abstract

International audience; Compound nucleus fission and quasi-fission are both binary decay channels whose common properties make the experimental separation between them difficult. A way to achieve this separation could be to probe the angular momentum of the binary fragments. This can be done detecting gamma rays in coincidence with the two fragments. As a case study, the reaction 32S + 197Au near the Coulomb barrier has been performed at the Tandem ALTO facility at IPN ORSAY. ORGAM and PARIS, two different gamma detectors arrays, are coupled with the CORSET detector, a two-arm time-of-flight spectrometer. TOF-TOF data were analyzed to reconstruct the mass-energy distribution of the primary fragments coupled with gamma multiplicity and spectroscopic analysis. Preliminary results of will be shown.

Abstract

Sensitivity analysis answers questions about the influence of parameters on the simulation results and plays a significant role in the development of environmental models by helping to understand the relations within the model and test its adequacy. Comparison of various sensitivity analysis approaches is often also quite useful because different methods employ different measures for ranking model parameters and their unconformities and disagreements provide additional information on model behavior. The visual representation of numerical results is crucial for their correct interpretation, and at first sight, the visualizations for the sensitivity analysis should be quite universal because in most cases an outcome of sensitivity analysis is the same: a set of indices measuring the significance of model inputs for the selected output. Surprisingly, it is not so straightforward. This paper compares visualization types suitable for the graphical representation of the sensitivity indices and demonstrates their benefits and caveats in different cases., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Abstract

Background: The present study reports the antibacterial potential of phyto-nano-hybrid particles Ag-CuO (silver-copper oxide) against drug-resistant pathogens isolated from a Russian hospital in Krasnoyarsk, Siberia. The synthesis of nano-hybrid was achieved by phytogenic source by using leaves of Murraya koenigii. The nano-hybrid particles were well characterized using hyphenated techniques and results of the antibacterial assay was tabulated., Results: The UV-visible spectra displayed absorption at 420 nm with the shoulder peak at 355 nm indicating the hybridization. The FTIR analysis revealed the presence of phenol, amine, methyl, carbohydrate and aromatic as major functional groups. The XRD analysis revealed the presence of Bragg's intensities at 2 theta angle depicting the crystalline nature of Ag-CuO nano-hybrid. The TEM analysis displayed the polydispered properties of Ag-CuO nano-hybrid with the size in the range of 60-80 nm exhibiting different shapes ranging from spherical, rod and oval. The antibacterial activity of Ag-CuO nano-hybrid was tested against multidrug-resistant pathogens that resulted in highest activity against P. aeruginosa strain with an inhibition zone of 14 mm in diameter. The MIC concentrations ranged from 0.3125 to 2.5 μg/ml and broth dilution assay displayed dose-dependent properties of Ag-CuO nano-hybrid particles., Conclusion: The obtained results are interesting to report the preliminary insight to develop biocompatible hybrid particles to combat drug-resistant pathogens. The developed nano-hybrid particles displayed activity against all the test pathogens investigated against both Gram-positive and Gram-negative bacteria. Thus, the study forms preliminary investigation to report nano-hybrid particles as broad spectrum antibacterial agents.

Abstract

Inhibition of the apical sodium-dependent bile acid transporter (ASBT, also known as IBAT - ileal bile acid transporter, SLC10A2) leads to disruption of the enterohepatic circulation of bile acids and their excretion with fecal masses. This is accompanied by cholesterol utilization for synthesis of new bile acids. ASBT inhibitors are promising drugs for the treatment of such diseases as non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, type 2 diabetes mellitus, necrotic enterocolitis, chronic constipation, atherosclerosis. To date the most known chemically synthesized inhibitors are: A3309, SHP626, A4250, 264W94, GSK2330672, SC-435. All of them are at different stages of clinical trials, which confirm the high efficacy and good tolerance of these inhibitors. Current trends in this field also include directed chemical synthesis of ASBT inhibitors, as well as their search among substances of plant origin.

Abstract

Meta- and pooled analyses are increasingly applied to aggregate the results of a number of studies, especially in health sciences. A typical difficulty is the presence of a publication bias. Usually Egger's regression test and funnel plots are applied to detect such a publication bias. A simulation study was conducted to investigate the quantity of null and negative results required to be omitted to detect a publication bias. In particular, the performance of Egger's test and funnel plots was considered in two scenarios with binary outcomes and expected odds ratios (OR) of 1 and 2, respectively. For both scenarios Egger's test detected only a small fraction of publication biases if few studies were deleted, corresponding to the results of a random deletion. Moreover, if a true null effect is present Egger's test is quite unlikely to detect a publication bias even if a considerable proportion of the null results are missing. Generally, the detection of a publication bias using Egger's test is only likely if both the "true" effect and the bias are large enough. Visual inspection of the funnel plots resulted in a higher fraction of detected publication biases in cases where a bias was present and in cases where studies were randomly deleted, revealing the arbitrariness of this method. Evidence indicates that standard methods for detection of a publication bias do not necessarily detect such a bias; thus, additional tests for publication bias need to be applied.
