Competencias científicas desarrolladas en equipos de trabajo: estrategia para el aprendizaje colaborativo de la quimioluminiscencia
Authors: Ospina Medina Andrés Camilo , Posada Rubiano Nestor Camilo
Published: September 2020

La educación escolar, al igual que el trabajo científico, los desarrollan grupos de personas que comparten una misma finalidad, ya sea aprender o llevar a cabo una investigación. En estos dos contextos es usual hablar sobre el trabajo en equipo y las habilidades que exponen los individuos que los componen. Los aspectos axiológicos y de competencias son la base para un buen desarrollo de la ciencia y la educación, pero se presentan hechos que afectan la actividad escolar. Las distribuciones grupales, la diferenciación en las asignaturas, grupos numerosos, etc., son algunas de las razones por las cuales el desarrollo y fortalecimiento de las habilidades científicas individuales y grupales se ven afectadas. Lo anterior expone una posible desarticulación entre la estrategia de enseñanza y el proceder de los estudiantes en el desarrollo de las ciencias. Mediante una estrategia de aprendizaje aplicada en el grado noveno del colegio Champagnat de Bogotá, basada en una metodología de etapas frente la temática de quimioluminiscencia, se desea enfatizar y propiciar el trabajo en equipo y las habilidades científicas, fundamentadas en la búsqueda de la articulación entre estas, las cuales son identificadas y registradas con instrumentos de carácter cuantitativo.

Determination of Secondary School Students' Levels of Sensitivity towards Cyberbullying and Cyberbullying Behaviour
Authors: GÜNDÜZ Şemseddin , AKGÜN Fatma , ÖZGÜR Hasan
Published: September 2020

The development of technology and especially the changes and innovations experienced in the development of mobile technologies have increased the use of such technological devices in the society. Mobile technologies and smart phones among them have positive effects both in social life and academic life, as well as situations that cause some negative use as a result of intensive use of such technologies. Cyberbullying behaviour, which aims to harm others' lives by using technological devices, comes to the forefront among these problems. Therefore, this study aims to investigate engagement in cyberbullying behaviour and the sensitivity towards cyberbullying, which is a common behaviour especially among secondary school students. The study was carried out with 747 secondary school students studying in the 5th and 6th grades of public schools in the fall term of the 2019-2020 academic year. “Cyberbullying Scale” and “Sensitivity towards Cyberbullying Scale” were used for data collection. Descriptive statistics, Mann Whitney U and Kruskal Wallis H and Spearman rho tests were used to evaluate the data that were found not to show normal distribution. As a result of the study, it was determined that the students' levels of engagement in cyberbullying behaviour were “low”, whereas their sensitivity levels towards cyberbullying were “high”. In the study, it was revealed that the difference between students' engaging in cyberbullying behaviour and their sensitivity towards cyberbullying in terms of gender and grade variables, and the difference between their cyberbullying sensitivity levels and mother education level, father education level, computer ownership, tablet ownership variables, were found to be significant. However, it was determined that there was a negative and moderate relationship between their cyberbullying behaviour and their sensitivity towards cyberbullying.
The Relationship between Cultural Intelligence and the Attitudes towards Refugee Students: A Study on Primary School Teachers
Authors: ALEV Sedat , KARA Mevlüt
Published: September 2020

This study aimed to examine the relationship between the cultural intelligence levels of primary school teachers and their attitudes towards refugee students. The sample of the study, which was designed using the correlational survey model among the quantitative research methods, consisted of 386 teachers working at primary schools in Nizip district of Gaziantep in the academic year 2019-2020. The data were collected through the “Cultural Intelligence Scale” and “Refugee Student Attitude Scale”. During the analysis procedure, mean scores and standard deviation for the variables were estimated, and the correlation and stepwise multiple regression analyses were performed. Based on the research findings, the cultural intelligence levels of teachers and their attitudes towards refugee students were relatively high. Moreover, there was a positive and significant relationship between the cultural intelligence levels of teachers and their attitudes towards refugee students. As a result of the stepwise multiple regression analysis, it was determined that the cultural intelligence level of teachers was a significant predictor of their attitudes towards refugee students. The second model yielded that the rise in the metacognitive, cognitive and motivational sub-dimensions of cultural intelligence significantly predicted teachers’ attitudes towards refugee students. It is advisable to create an atmosphere that may improve the cultural intelligence level of teachers at schools and to contribute to their development of positive attitudes towards students. The present study was carried out through the quantitative research methodology, and it has been recommended to examine the relationship between the variables in detail with the studies to be designed with qualitative or mixed methods in future research.

Authors: Hernandez Rollan Cristina , Bach Falkenberg Kristoffer , Rennig Maja , Birk Bertelsen Andreas , Norholm Morten
Published: September 2020

E. coli is a gram-negative bacteria used mainly in academia and in some industrial scenarios, as a protein production workhorse. This is due to its ease of manipulation and the range of genetic tools available. This protocol describes how to express proteins in the periplasm E. coli with the strain BL21 (DE3) using a T7 expression system. Specifically, it describes a series of steps and tips to express "hard-to-express" proteins in E. coli, as for instance, LPMOs. The protocol is adapted from Hemsworth, G. R., Henrissat, B., Davies, G. J., and Walton, P. H. (2014) Discovery and characterization of a new family of lytic polysaccharide monooxygenases. Nat. Chem. Biol.10, 122–126. .

Authors: Popp Sarah , Dhounchak Sarita , Simeonovic Charmaine
Published: September 2020

Isolated mouse islets were dispersed into single cells using Accutase (Millipore; 250 µl/500 islets. 40,000 islet cells were transferred to individual wells of a 96 well culture plate (CELLSTAR) for staining and flow cytometry analysis or for culture. For intracellular staining, isolated islet cells were fixed and permeabilised using BD Fix/Perm (BD Biosciences) . After a blocking step, the cells were stained with primary antibodies (anti-mouse collagen type XVIII (Col18), anti-mouse CD138 (anti-syndecan-1 (SDC1), anti-mouse CD44, anti-human HS (10E4) or HP3/17 anti-human heparanase (HPSE)) and incubated with fluorescent secondary antibodies. Events were collected using a BD LSR Fortessa flow cytometer with BD FACS DIVA software (version 8). Data was analysed using FlowJo software (version10.0.7, TreeStar Inc.).
Kidney biopsy findings in vancomycin-induced acute kidney injury: a pooled analysis v1
Authors: Bellos Ioannis
Published: September 2020

Vancomycin represents a tricyclic glycopeptide that is widely administered to patients with Gram-positive infections. Acute kidney injury is considered as an important adverse effect, as it commonly leads to significant morbidity and high rates of treatment discontinuation. Vancomycin has been suggested to be associated with acute tubular necrosis and tubulointerstitial nephritis; however, evidence regarding kidney lesions is currently scattered, coming exclusively from case reports. The aim of this study is to accumulate literature studies with biopsy-proven cases of vancomycin-induced nephrotoxicity and assess the effects of histological findings on renal prognosis. Survival analysis is planned to be performed in order to identify which kidney lesions are linked to lower rates of renal recovery.
Negative Consequences of Innovation-Igniting Urban Developments: Empirical Evidence from Three US Cities
Authors: Zandiatashbar Ahoura , Kayanan Carla Maria
Published: September 2020

Emergent economic development policies reflect the challenges urban growth coalitions face in attracting the footloose tech-entrepreneurs of the global economy. This convergence between the focus on place and the harnessing of global capital has led to the proliferation of innovation-igniting urban developments (IIUD)—place-based economic development strategies to boost the local knowledge economy. Economic developers are using IIUD strategies to convert areas of the city into entrepreneurial “launch pads” for innovation. However, because these developments remain young, considerations to implement IIUDs lack an evidence-base to show the potential for negative consequences on the communities where they are embedded. This research addresses this gap through: 1) a review of studies of similar developments to identify negative consequences; and 2) using a quasi-experimental method composed of Propensity Score Matching and Average Treatment Effect analyses from IIUDs in three US cities (Boston, MA, St. Louis, MO, and Buffalo, NY). Combined, results demonstrate that the greatest implications of IIUDs are the increased polarized division of labor, housing unaffordability, and income inequality. As IIUDs gain in popularity, it is critical to correlate negative consequences with IIUDs to inform economic developers in assessing trade-offs.
Palaeoenvironmental Interpretation of the Upper Triassic Baluti Formation in two selected sections at Amediya District, Kurdistan Region- Iraq: Insights from Palynofacies Study
Authors: Azo Nahida , Hanna Majeed , Edilbi Ayad
Published: September 2020

Palynofacies analysis was carried out on 28 outcrop samples from the Upper Triassic Baluti Formation from Zewa and Sararu Sections in south and northwestern of Amediya District respectively, Kurdistan Region- Iraq. Based on the studied palynofacies, both sections are quite different in terms of depositional environment. Four types of palynofacies were recognized as following: the palynofacies type IV (Pl.1) is observed in the lower, middle and upper portions of upper part of Zewa Section in which, is characterized by high amount of phytoclasts, medium percentage of amorphous organic matter (AOM) and palynomorphs. This facies is referred to a depositional area that is located relatively nearshore with an arid hinterland, the palynofacies type V (Pl.2) was observed in lowermost and middle portions of upper part of Zewa Section, which is characterized by high domination of palynomorphs (mainly bisaccates and monosaccate pollen grains) and a less amount of phytoclasts and AOM. This facies indicates the domination of shallow marine to continent environment. The palynofacies type VI (Pl.3) was observed in middle and upper portions of upper part of the Zewa Section and lower and upper parts of the Sararu Section. This facies showed less amount or absence of palynomorphs, and relatively high amount of AOM and phytoclasts. In addition to this, a remarkable percentage of dinoflagellate cysts in Sararu Section has been found in this facies. This facies indicates proximal suboxic-anoxic shelf, and palynofacies type IX (Pl.4) was observed in middle to upper part of Sararu Section and characterized by less amount or absence of palynomorphs with high amounts of AOM and phytoclasts, which represents a deep environment of deposition.
Computational study on molecular structure, vibrational spectrum analysis and acidity strength of P4On (n = 6-10) phosphorus oxides with cage structure
Authors: KARAKAŞ Duran
Published: September 2020

In this study, molecular structure, IR spectra and acidity strength of P4On (n = 6-10) type phosphorus oxides with cage structure were investigated at the PBE1PBE/6-311+G(2d) level. Structural parameters and IR spectra of oxides were obtained from optimized structures. From the structural parameters and IR spectra, P4O6 and P4O10 molecules were found in Td symmetry, P4O7 and P4O9 molecules in C3v symmetry and P4O8 molecule in C2v symmetry. Symmetry labeling of the peaks in the IR spectra of oxides was performed.To predict the acidity strength of the oxides in the gas phase, the protonated species were optimized at the PBE1PBE/6-311+G(2d) level. Proton affinity values were calculated using the total energies of neutral and protonated species. Acidity strength ranking according to proton affinity values was obtained as P4O6 < P4O7 < P4O8 < P4O9 < P4O10.
Summarising big data: public GitHub dataset for software engineering challenges
Authors: ŞEKER Abdulkadir , DİRİ Banu , ARSLAN Halil , AMASYALI Fatih
Published: September 2020

In open-source software development environments; textual, numerical, and relationship-based data generated are of interest to researchers. Various data sets are available for this data, which is frequently used in areas such as software engineering and natural language processing. However, since these data sets contain all the data in the environment, the problem arises in the terabytes of data processing. For this reason, almost all of the studies using GitHub data use filtered data according to certain criteria. In this context, using a different data set in each study makes a comparison of the accuracy of the studies quite difficult. In order to solve this problem, a common dataset was created and shared with the researchers, which would allow to work on many software engineering problems.
The comparison of inflammatory markers in pentylenetetrazole-induced acute epileptic seizure model and chronic epilepsy model in rats
Authors: TAŞKIRAN Ahmet Şevki , TAŞTEMUR Yaşar
Published: September 2020

Recent studies have provided important evidence that neuroinflammation has an effective role in epilepsy pathophysiology. However, it is not clear that the occurrence of neuroinflammation is related to one epileptic seizure or repeating seizures. Therefore, we aimed to investigate the comparison of inflammatory markers in pentylenetetrazole-induced acute epileptic seizure model and chronic epilepsy model in rats. In this study, 18 male Wistar albino rats were used. The animals divided into three groups as control, acute epileptic seizure model and chronic epilepsy model. Inflammatory markers (TNF-α, IL-1 β, COX-1, and COX-2) were measured by using ELISA methods in the cortical and hippocampal brain regions after completing the epileptic model procedure. Statistical evaluation of the data was performed by one-way ANOVA and multiple comparisons were determined by the Tukey test. Statistical significance was defined at p<0.05. Obtained data show that there was significant increase in inflamattory markers in chronic epilepsy model compared to the control and acute epileptic seizure model (p<0.05). In conlusion, this study may suggest that inflammatory sytem is related to epileptogenesis process rather than only one epileptic seizure.

Authors: KARATEPE Arzu , ÇETİN Ahmet
Published: September 2020

The present research was undertaken to determine the effect of substituted 2,2'-[(2R,3R)-2,3-dihydroxy-1,4-dioxobutane-1,4-diyl]bis(N-R-hydrazine-1-carbothioamide and (1R,2R)-1,2-bis[5-(R-amino)-1,3,4-thiadiazole-2-yl]ethane-1,2-diols on the antioxidant status of the yeast Saccharomyces cerevisiae cells. This cell serves a good eukaryotic model system for the study of molecular mechanisms of oxidative stress. The Saccharomyces cerevisiae yeast cells were treated a series of 1,2-diols and thiadiazoles compounds and the malondialdehyde (MDA) and antioxidant vitamins (A, E, C) levels in the medium were measured by HPLC-UV. In the comparison done among groups, the MDA which is an indicator of lipid peroxidation and Vitamin E concentrations were showed statistically changed in the samples. Exposure of yeaset cells to L9 showed an increase in MDA and decrease in vitamin E levels but L2 and L8 showed decrease in MDA and increase in vitamin E levels. The results showed that compounds L9 caused a considerable oxidative stress and L2 and L8 have antioxidant activity.

Authors: Sokolova N. A.
Published: September 2020

Ensuring security in the Arctic in various areas and the need for a better understanding of the natural processes occurring in this region require intensification of scientific and technological cooperation, which opens up opportunities for closer interaction to solve other problems, for example, environmental protection, adaptation to climate change, safe maritime navigation and so on. Scientific and technological cooperation in the Arctic is carried out in various formats. The Arctic Council continues to play a peculiar coordinating role in international scientific cooperation, which has proposed various initiatives related to the development of scientific cooperation. The author emphasizes the implementation of scientific cooperation in the context of the scientific diplomacy development as an integral process in the information society, when scientific data is important for diplomatic activity, when diplomacy provides conditions for the development of international scientific cooperation, and finally, when science affects the vectors of cooperation, ensuring the solution of problems in various areas. Particular attention is given to the analysis of the 2017 Agreement on Enhancing International Arctic Scientific Cooperation, since the problems existing in the Arctic region require coordinated and carefully planned collective actions. Issues related to the types of research activities, the specifics of the spatial scope of the Agreement and access to the established geographical areas are considered. Finally, some conclusions are proposed regarding the assessment of the Agreement. The agreement improves the quality of the legal environment for all 8 Arctic states simultaneously in terms of scientific cooperation, taking into account the relevant provisions of international law, including those related to marine scientific research.

Narodziny obowiązkowych ubezpieczeń nieruchomości kościelnych na ziemiach polskich
Authors: Bednaruk Waldemar
Published: September 2020

Idea obowiązkowego ubezpieczania budynków kościelnych od ognia została wprowadzona na ziemiach polskich na większą skalę w 1803 r. Jako pierwszy zastosował ją w praktyce zaborca pruski, jednak po utworzeniu Królestwa Polskiego zachowano przymusowe ubezpieczenia od pożarów na tych ziemiach podległych teraz władztwu rosyjskiemu. W ten sposób na znacznym obszarze ziem polskich pod zaborami rozciągnięto tytułowy obowiązek, przyzwyczajając ludność do nowych sposobów zabezpieczania swojego majątku przed skutkami nagłych i niespodziewanych zdarzeń losowych. Po utworzeniu niepodległego państwa polskiego obowiązkowe ubezpieczenia nieruchomości kościelnych od ognia zostały uznane za normę obowiązującą na przeważającym obszarze kraju. Wyjątkiem pozostawały ziemie dawnego zaboru pruskiego, które nie zostały objęte przymusem asekuracji budowli od ognia.

Celem artykułu jest analiza projektu prawa małżeńskiego Karola Lutostańskiego z 1929 r. przeprowadzona w ujęciu porównawczym z rozwiązaniami prawnymi obowiązującymi w Rosji Radzieckiej. Zasadność uwzględnienia komparatystyki uzasadnia powoływanie się przez obóz konserwatywny II Rzeczypospolitej na zbieżność treści i założeń projektu Lutostańskiego z bolszewickim ustawodawstwem małżeńskim. Stanowisko takie bezpośrednio stało się przyczyną tego, że projekt nie uzyskał mocy obowiązującej. Wyniki przeprowadzonych badań wskazują na istnienie istotnych rozbieżności tak w samych założeniach proponowanej regulacji, jak i w zredagowanych w niej przepisach kształtujących model małżeństwa i rodziny, a w konsekwencji państwa. W odróżnieniu od prawa obowiązującego w Rosji, polski projekt w zamierzeniu faktycznie chronił instytucje małżeństwa i rodziny.
Trajetórias e possibilidades: caminhos percorridos por fotógrafas imigrantes na cidade de São Paulo
Authors: Hallal Maria Clara Lysakowski
Published: September 2020

Este trabalho tem como objetivo analisar a relação entre ser imigrante e a influência dessa situação no reportório fotográfico das fotografas Madalena Schwartz e Claudia Andujar, ambas imigrantes, vieram para o Brasil nas décadas de 1960 e 1955, respetivamente. Para a realização do trabalho, foram selecionadas quatro fotografias, duas de cada profissional. A metodologia utilizada é baseada em Augusto Pieroni (2003), que conceitua a divisão da análise fotográfica em: contextos internos (película, arquivos de negativo, trabalhos publicados) e externos (agenciamentos), formas (enquadramentos, planos focais, cores, linhas) e conteúdos (temas, referencias intencionais, sentidos). Por meio da análise imagética, foi possível perceber certo estranhamento ao diferente e desconhecido, fruto da vivência associada aos imigrantes e retratada nas imagens selecionadas. Dessa forma, podemos entender que as fotógrafas viam a si mesmas; o ato de imigrar, os desafios da mudança de seus países de origem, as questões de gênero presentes e as tensões decorrentes disso são questões que se refletem nas fotografias obtidas.

The effect of syngas dilution with nitrogen on the activity, selectivity and capacity of the Fischer–Tropsch reactor with a fixed granulated catalyst bed was studied during the synthesis at the integrated pilot plant for conversion of natural gas to syncrude. Experimental data were obtained at different nitrogen content in syngas: up to 2, 50 and 70 %. The analysis of experimental data shows that the dilution of syngas increases the selectivity to C5+ and decreases the selectivity to methane. The decrease in the reactor capacity observed upon dilution of syngas can be compensated by increasing the syngas flow rate. A decrease in the pressure of the Fischer–Tropsch synthesis from 2 to 1.5 and 1.0 MPa was shown to exert a detrimental effect on the catalytic performance of the process carried out with a twofold dilution of syngas at its hourly space velocity of 4000 h–1.

Published: September 2020

Analysis of agricultural products is an important area that is widely emphasized today. In this context, with the development of technology, computer-aided analysis systems are also being developed. In this study, a system has been proposed for classifying maize seeds as haploid and diploid using pre-trained convolutional neural networks. For this purpose, AlexNet, GoogLeNet, ResNet-18, ResNet-50, and VGG-16 pre-trained models have been used as feature extractors for the haploid and diploid seed classification process. In the first stage, the deep features of haploid and diploid maize seeds have been obtained in these models. The features have been taken from different layers of network architecture. Instead of softmax classifier in the last layer of the network, classifiers based on decision tree, k-nearest neighbor, and support vector machine have been used. According to the classification results with these features, the achievements in network architectures and classifier methods have been observed. The experiments have been carried out on a publicly available dataset consisting of 3000 haploid and diploid maize seed images. The experimental results revealed that the developed classification systems demonstrate a remarkable performance.
Effect of emulsion formulation on characteristics of pea protein-stabilized oil-in-water emulsions
Authors: CAN KARAÇA Aslı
Published: September 2020

The goal of this study was to investigate the effect of emulsion formulation on characteristics of oil-in-water emulsions. Varying concentrations of biopolymers including maltodextrin, gum arabic and pea protein were used in the formulation of emulsions created according to an extreme vertices design. Mean droplet size of oil-in-water emulsions changed between 0.9-2.5 µm and decreased with increasing pea protein concentration. Creaming stability ranged between 9-100% and increased as the concentration of pea protein increased. The results of this research suggest that pea protein can be utilized as an emulsifier for oil-in-water emulsions with low oil concentration as it has the ability to decrease the mean droplet size and increase creaming stability of the emulsions.
Socio-Political Mechanisms of Constructing Contemporary Regional Myth: The New Past for the Republic of Tatarstan
Authors: Ovchinnikov Alexander
Published: September 2020

The article analyzes socio-political conditions in which contemporary myths about the regional past are constructed. It focuses on ethno-national histories, which are integral to the current ideologies of ‘national republics’ in the Russian Federation. In the 1990s, the Republic of Tatarstan, situated in the middle Volga region, epitomized the ‘parade of sovereignties’ of ethnic regions of Russia. The political drift towards sovereignty was reproduced in regional history writing. Since the early 2000s, however, as the ‘vertical of power’ has been strengthened, attempts were made to develop a unified historical canon for the whole of Russia. At present Tatarstan’s historical narrative follows the preferences of the regional political elite, which aims at creating a separate segment in the puzzle of Russia’s ‘new past’ while mitigating conflictual entanglements of common history. Nevertheless, the  History of  Tatarstan was not subsumed by the  History of Russia, and this disciplinary independence – inherited from the History of  Tatar  Soviet Socialist Republic – facilitated the fast ‘sovereignization’ of regional history. The separate historical narrative of Tatarstan persistently brings up the concept of ‘Tatar world, which competes in a way with its Russian counterpart – ‘Russian world’. The competition between the federal and regional levels of history writing is caused by the administrative and territorial division of Russia rather than by the genuine ‘struggle of ideas’ and it reflects the complexity of imperial legacy rather than confirms the emergence of a civic nation.
Keywords: myth, ethno-national history, Tatarstan, Bolğar, ‘Tatar world’
Descrição lexical histórico-comparativa de mudanças fonológicas dos sinais da língua francesa para as línguas americana e brasileira de sinais
Authors: Abreu Walber Gonçalves de , Salvador Carlene Ferreira Nunes
Published: September 2020

O interesse dos franceses em educar os surdos possibilitou que a língua de sinais francesa – LSF se desenvolvesse e influenciasse o surgimento de outras línguas de sinais como a Americana – ASL e a Brasileira – Libras, estabelecendo, portanto, um grau de parentesco entre essas línguas. Diante disso, o objetivo deste trabalho é descrever as mudanças ocorridas da LSF para a ASL e a Libras e demonstrar quais os processos fonológicos envolvidos nessas mudanças. Selecionamos 21 sinais, 7 de cada língua de sinais que identificamos terem semelhanças paramétricas. Após seleção e organização dos dados, analisamos esses sinais qualitativamente e então, identificamos tendências gerais de mudanças fonológicas. Concluímos que os sinais da ASL sofreram mudanças mais consideráveis do que da Libras e que na ASL houve uma tendência em deslocar os sinais que eram realizados na locação boca, na Libras isso ocorreu apenas em 2 sinais, os demais sofreram apenas algumas mudanças simples em sua constituição paramétrica. A partir dos dados, identificamos três tendências gerais de mudanças.

The article discusses typical tasks of quantitative comparison and analysis of efficacy of diagnostic medical technologies. The authors discuss the indicators of clinical informativeness of diagnostic methods in otorhinolaryngology, the quantitative methods for their calculation and interpretation, their importance for making diagnostic decisions. Using one of the diagnostic methods as an example, they describe the algorithms for comparison of the studied diagnostic test with the “gold standard” test according to clinical information indicators: sensitivity, specificity, positive and negative predictive value, accuracy, the ratio of positive and negative test result likelihood. The authors consider the problems of constructing ROC (receiver operating characteristic) curves using the example of diagnostic indicators of nasal obstruction: airflow and pressure, as well as the calculation and presentation of AUC (area under curve, in one figure), finding diagnostic threshold points for two tests (the changes in flow and resistance), and testing the statistical hypothesis about the equality of AUC of these two tests, building of nomogram for calculation the post-test disease probability of disease. It is shown how all the standard operational characteristics of diagnostic medical technologies and additional useful indicators can be efficiently calculated using the presented method. All calculations were performed in the statistical program R. The text of the article contains program codes of the R language with explanations.

The obstruction of nasal breathing due to vasomotor rhinitis is quite a common cause of visits to the ENT doctor. Today, it is believed that therapeutic measures should begin with the identification of possible causes that result in the formation of nasal hyperreactivity, and the treatment of the underlying disease. Medical treatment of vasomotor rhinitis can begin with the prescription of topical corticosteroids and antihistamines. The long-term observations have shown that the use of decongestants and topical steroids in the preoperative period reduces reactive phenomena in the nasal cavity after surgical treatment. To objectify the empirical observations, the authors have examined 20 patients after surgical intervention for vasomotor rhinitis in the scope of submucosal vasotomy. In the postoperative period, the patients were recommended regiminal and restrictive measures, and prescribed antihistamines and local irrigation therapy with warm saline. The authors assessed the transport function of the nasal cavity mucous membrane by the study of mucociliary transport rate in the test with coal dust and the respiratory function of the nasal cavity by the volumetric flow rate using anterior active rhinomanometry. The study revealed that the use of decongestants and topical steroids in the preoperative period reduces the reactive events in the postoperative period and shortens the patient’s rehabilitation period.
