Comparison of Nitroaromatic Compounds Metabolites Types by Sequencing Performance of Anaerobic-Aerobic and Aerobic-Anaerobic Processes
Authors: Teimouri Fahimeh , Amin Mohammad Mehdi , Sadani Mohsen , Bina Bijan , Khanahmad Hossein
Published: December 2022

Introduction: Xenobiotic contamination is a global concern. Nitroaromatic compounds enter the environment through ammunition, ordnance disposal, burning the outdoors, and leakage of ammunition. Thirty percent of explosives enter the environment without any change, which can cause pollution of soil, water, and health concerns. So, effective remediation of the contaminated area is necessary.
Materials and Methods: Soil bioreactors consisted of plastic pans placed in larger pans. Explosives were analyzed using a High-Performance Liquid Chromatography (HPLC) system, Model 486 UV detector, and a Nova Pak C18 guard column. LC-MS detected intermediates on an RP18 analytical column equipped with a C18 guard column.
Results: Rhamnolipid significantly affected 2,4,6-trinitrotoluene (TNT) and Pentaerythritol tetranitrate (PETN) biodegradation rates with the help of indigenous bioaugmentation. The mentioned condition was also effective on the maximum bacterial growth in various nitroaromatics (S0) concentrations, in which the top change occurred. The specific growth rate was foremost in a setup containing microbial inoculated and biosurfactant (0.19) responding to 800 mg/kg TNT and 150 mg/kg PETN. The maximum bacterial enumeration of sludge and biosurfactant were 4.8 × 108 and 4.1 × 108 CFU/g, respectively. The aerobic-anaerobic sequence could be able to produce less harmful metabolites. In an aerobic-anaerobic sequence process, using the anaerobic process could help complete the azo compounds degradation in the aerobic stage.
Conclusion: Aerobic-anaerobic condition is suitable for bioremediation contaminated explosive sites and achieving complete mineralization. Generally, this proposed method is possible for in situ bioremediation.

Published: December 2022

The usage of Liquefied Petroleum Gas in households has been to increase in recent years. The energy used by households has proved difficult to forecast due to the nature of the independent variables. In recent years, deep learning models has been broadly utilized in the machine learning area to model time series data. Most noticeable is in the field of forecasting. In this work, Neural Network Autoregressive model (NNETAR), Naive forecasting and the Autoregressive Integrated Moving Average (ARIMA) models were used to model the price of Liquefied Petroleum Gas prices(LPG) of 37 states (including the FCT) in Nigeria, with input variables in the form of the price of refilling LPG for 12.5 kg from January 2016 to April 2019 covering a 1480 data points. The Mean Absolute Percentage Errors was used to measure the performance of the model. The result shows that Naive produced lower MAPE for more states compare to NNETAR and ARIMA models.
Evaluación de estilos de pensamiento de profesores en la escuela: Un estudio de caso
Authors: Rodríguez-Peralta Juan
Published: December 2022

Los estilos de pensamiento docente son un marco de referencia que forma parte de la psicología educativa y orienta la enseñanza y el aprendizaje. El objetivo de esta investigación fue analizar los estilos de pensamiento aplicados por los docentes del nivel de educación primaria. Se realizó un estudio transversal con el objetivo de conocer la prevalencia de los estilos de pensamiento docente de una cohorte de 107 docentes seleccionados aleatoriamente de seis escuelas primarias del área urbana de la ciudad de Cuenca en Ecuador, respectivamente: 2 públicas, 2 públicas/religiosas, y 2 privadas. Para recolectar la información se utilizó el Cuestionario Estilos de Pensamiento en la Enseñanza de Grigorenko y Sternberg, validado por Serrano (1994). La investigación revela que los docentes examinados aplican principalmente un estilo de pensamiento creativo (Tipo 1), estilo que corresponde a los lineamientos psicopedagógicas emitidos por el Ministerio de Educación para la orientación de la enseñanza. La investigación también mostró que el estilo de pensamiento de los docentes de las escuelas públicas tiende más hacia el estilo de pensamiento normativo (Tipo 2) en comparación con los docentes de las escuelas privadas. Factores como la edad, el género y el grado en el que labora el docente parecen no incidir en el estilo de pensamiento que emplean los profesores.

Authors: Barros-Esquivel Katia , Cabrera-Barona Pablo , Durán-Saavedra Gustavo
Published: December 2022

La estigmatización territorial es un fenómeno que surge como resultado del etiquetamiento y estereotipación de un determinado lugar, y la consiguiente discriminación y pérdida de estatus. Este fenómeno está estrechamente relacionado con la disminución de los vínculos y las relaciones sociales de la población estigmatizada, y la concentración de barrios en condiciones de precariedad semejantes. La presente investigación estudia un barrio ampliamente estigmatizado de la periferia de la ciudad de Cuenca, Ecuador, mediante la aplicación de enfoques cuantitativos y cualitativos (entrevistas, grupos focales, modelos de regresión). Los resultados principales del estudio permiten concluir que la estigmatización territorial al estar vinculada con el aislamiento social de la población estigmatizada y la segregación residencial del barrio en general influye en la situación laboral de su población con respecto a las posibilidades de acceso al mercado laboral generando impactos negativos que se sobreponen a carencias previas.

El diagnóstico de pacientes con dispepsia representa un desafío ya que en la mayoría de los casos se requieren observaciones endoscópicas complejas y costosas. En este estudio, evaluamos el rol del diagnóstico de la calprotectina fecal en pacientes con dispepsia. Para ello, en el año 2019 se realizó un estudio observacional en 149 pacientes con dispepsia registrados en el Centro de Especialistas en Gastroenterología de la entidad privada Cuenca, Ecuador. Los datos disponibles abarcaron edad, sexo, signos de alarma, valores de calprotectina fecal (CF) y hallazgos endoscópicos. Los pacientes en el grupo de edad >65 años fueron los más representados, el 56.4% de la población eran del sexo femenino, el 48.57% eran CF positivos de los cuales el 86.8% poseían valores significativos de CF. CF+ se asoció significativamente con los hallazgos por EDA/colonoscopia (p<0.001). Las patologías más diagnósticas en pacientes con CF+ fueron gastropatía congestiva, metaplasia intestinal, giardiasis y poliposis. La CF se correlacionó positivamente con la presencia de hallazgos patológicos en las pruebas diagnósticas invasivas (r=0.298) y es un biomarcador no invasivo útil que se correlaciona positivamente con los hallazgos endoscópicos en el tracto gastrointestinal de pacientes con dispepsia.

Authors: Furashov A.S. , Arbekov A.N. , Vasenina P.M. , Mitrofovich V.V. , Semilet N.A.
Published: December 2022

The article considers a comparison of the methods for simulating the flow in the fan impeller with the meridional acceleration of the flow. The aim of this work is to compare the results of flow simulation obtained using the method of calculating the flow along axisymmetric current surfaces with variable thickness in relative motion with the solution obtained by the CFD method. The discrepancy between the results of determining the pressure for the test problem --- the flow in an elementary blade row is not exceeded 2 % with a continuous flow. The resulting distribution of velocity along the contour of the blade makes it possible to proceed to the calculation of the boundary layer on its surface and to take into account the profile losses in the rotor, as well as to clarify the location of the trailing points on the profile. The presented work shows the possibility of using the method of calculating the flow along axisymmetric current surfaces with variable thickness for profiling axial fans with meridional flow acceleration. The rotor was profiled using the method described in the article and a CFD calculation was performed, which confirmed the theoretical head coefficient Ht = 0.68 laid down during profiling at a given flow rate ca1 = 0.5, the total efficiency in the rotor was η∗f.i = 0.93
Convective Heat Transfer and Friction in a Thin Laminar-Turbulent Boundary Layer on the Permeable Surface of a Blunted Cone of Small Elongation
Authors: Gorskiy V.V. , Savvina A.G.
Published: December 2022

Solving the problem of calculating convective heat transfer and friction in the laminar-turbulent boundary layer involves the need for numerical integration of differential equations, supplemented by those or other semiempirical models of apparent turbulent viscosity, which should be validated on the results of experimental studies, carried out in conditions, providing simulation of the gas dynamic picture of body flowing by a gas stream. Unfortunately, at present, there are no literature data on studies of laminar-turbulent heat exchange on the permeable surface of a blunted body, and under these conditions, one has to go by the way of comparing the calculated data with the results of experiments carried out on sharp bodies. Literature sources describe the results of studies carried out for a hemisphere, in which one of the semi-empirical models of apparent turbulent viscosity is used, tested on the results of experiments carried out on the impermeable surface of such shaped body. In this case, it was possible to obtain a physically consistent picture of the influence exerted by blowing gas through the wall on the degree of blocking of the convective heat flow. In the absence of qualitative experimental data on this issue, it seems reasonable to apply in practice the considered semi-empirical model of apparent turbulent viscosity to estimate the degree of blocking of convective heat flow and friction under the specified conditions. This article is devoted to the solution of a similar problem for the lateral surface of a blunted cone

Published: December 2022

An installation for studying the dynamics and carrying capacity of a single-stage magnetic rotor suspension has been created. The evaluation of the proposed installation with regard to its potential use was carried out. The possibility of creating a rotor suspension based on hybrid active magnetic bearings was investigated with the help of the setup. If hybrid active magnetic bearings are used, the magnetic rotor suspension will allow to replace the existing classical active magnetic bearings used in vacuum, cryogenic and pumping equipment, reducing the energy costs without changing the geometric parameters of the existing units' housings. Experimental research of characteristics of axial active electromagnet is conducted (minimum power required to keep the rotor in vertical position is obtained). A finite-element model of the axial active magnetic bearing is created. The calculation results of the model are compared with the experimental data and the inductive transducer is calibrated. Experimental installation of a single-step rotor magnetic suspension is designed and manufactured. An electrical circuit for controlling the experimental setup is assembled. The program for PID-controller is given and its principle of operation is described with respect to the specified installation

Published: December 2022

The descent of a stabilized capsule from a low near-earth orbit along a ballistic trajectory is considered. The descent of a stabilized capsule from a low Earth orbit along a ballistic trajectory is considered. A reliable preliminary estimate of the intensity of the thermal impact of the air flow, which enters the surface of the capsule, is the equilibrium temperature of this surface. The value of the equilibrium temperature follows from the condition of equality of the density of the total heat flux brought to the surface and the density of the heat flux, removed due to the own radiation of this surface. Based on the peculiarities of the heat exchange process on the surface of the spherical blunt capsule three sections of the trajectory are distinguished. At free-molecular flowing of the blunt, at the section of descent the intensity of heat exchange is assumed to be proportional to the energy of the molecule flow. At the section corresponding to the continuum flow regime, the intensity of convective and radiative heat transfer is estimated by empirical dependences obtained by processing the calculated and experimental results. When combining laminar and turbulent flow modes on the attenuation surface, the highest of two local values of convective heat flux density is taken. At the intermediate section of the descent, the Knudsen number is taken as an argument determining the intensity of convective heat transfer, and empirical dependences are used to estimate the radiation component. A quantitative analysis of the change in the time of descent of the maximum value of the equilibrium temperature on the blunted surface for a ball capsule and a capsule with a ball segment was carried out. The results of such analysis are the purpose of the present work and allow to identify the most heat-stressed areas of the descent trajectory on the blunt surface at the preliminary stage of the design and to choose the acceptable materials of the thermal protection coating

Authors: Klishin A.N. , Kolesnikova D.S.
Published: December 2022

Creation of aircraft control systems that provide high quality guidance is an urgent task associated with increasing efficiency of the modern missile systems. Classical autonomous guidance systems without integration with any other external correction systems are making it impossible to ensure high-precision target engagement. An approach based on the use of adaptive guidance system is proposed. Besides, an approach to synthesis and analysis of the self-tuning aircraft control system that implements terminal homing is illustrated. A technique for forming the control system structure is presented ensuring the control quality constant level in all operating modes due to self-tuning of the constituent elements variable coefficients. Structural schemes and control equations were determined to correct the aircraft flight. Implementation of the developed technique on board the aircraft is proposed determining relationship between the aircraft control system parameters and the apparent acceleration. Adaptive system operation is demonstrated on a typical model of the aircraft flying in the atmosphere with guidance at the stationary target. Results of numerical simulation are presented, and high efficiency of the developed technique is revealed

Authors: Timofeev G.A. , Yaminskiy N.A. , Samoilov D.E.
Published: December 2022

The development of automatic control systems, tracking systems and industrial robotics requires the creation of new generation drive systems with high efficiency, kinematic accuracy, reliability, durability with small axial and radial dimensions and weight. To implement tracking systems with power differentials, transmission mechanisms with two degrees of freedom are required to provide the transformation and summation of two movements of drive motors into the required movement of the drive output shaft. These requirements in single-channel tracking systems are well met by strain wave gears (SWG) with low-inertia disk and ring wave generators. They allow for wide layout possibilities, the ability to route cables through the hollow central shaft of the drive, high torsional rigidity and low moments of inertia, which are in the range of 250 to 400 times less than those of cam wave generators, thus ensuring high drive speed. There are practically no publications, except domestic ones, devoted to the study of SWG with ring wave generators. This scientific direction of research is carried out at the Bauman Moscow State Technical University. Structural schemes of SWG with ring generators of external deformation waves are considered, the features of the kinematics of these gears are studied, and recommendations for improving their quality indicatorsare proposed

Published: December 2022

The article presents the main results of an experimental study of the operation of a nitrogen rectification column of a high-pressure air separation unit TKDS-100V developed by JSC "NPO "Geliymash" as an alternative to the installations of the previous generation AKDS-70M. The declared productivity of these units is much higher in comparison with the predecessor, the concentration of the products obtained meets the requirements and is ensured by the use of efficient heat and mass transfer devices of its own production. However, the experience of operating the TKDS-100V air separation unit has revealed a number of significant disadvantages. The unstable operation of the air separation unit of the TKDS-100V unit, caused by both constructive miscalculations and errors in the operational documentation, leads to operational disadvantages. The evaluation of the mass productivity of the TKDS-100V unit in the mode of liquid nitrogen production has been carried out. Based on a detailed analysis of empirical data, the reason for the oscillatory nature of the processes occurring in the column has been established, which significantly complicate the operator’s work, exclude the possibility of maintaining a rational mode and often lead to emergency situations associated with the parameters going beyond the limits of acceptable values. Deficiencies in the design of the rectification column leading to a pulsating supply of reflux from the pockets of the condenser to the upper rectification plate are identified and solutions are proposed

Authors: Patil S.S. , Rathod B.S. , Pawar M.M. , Chaudhary A.B. , Modi C.P.
Published: December 2022

Background: Zinc is found in very high concentration in semen and male reproductive tract and acts as a hormone receptor modulator for testosterone production in Leydig cells. Thus, it plays a very important role in male reproduction. Moreover, Indian soils are very deficient in zinc as per earlier reports and recent studies have shown that supplementation of zinc has improved qualitative as well as the quantitative aspects of semen quality in bulls. So, a study has been planned to study the effect of organic zinc supplementation on semen production and quality in kankrej bulls. Methods: A total of 8 healthy Kankrej bulls under semen collection were selected for the study. Basal diet (concentrate mixture, green and dry fodder) was fed during pre-supplementation and zinc propionate @ 100 ppm/bull was supplemented to the basal diet during post-supplementation for a period of 60 days to complete one spermatogenic cycle. A total of 128 ejaculates (64 pre-supplementation and 64 post-supplementation) were collected. Result: Mean semen volume was non-significant (P greater than 0.05) between the treatment groups. Mean sperm concentration was 1325.68±80.08 and 2162.36±112.0 million/ml pre- and post-supplementation, respectively. Feeding of zinc propionate significantly (P less than 0.01) increased semen sperm concentration. The average mass motility of sperms was significantly (P less than 0.01) higher during post-supplementation (3.92%) than the pre-supplementation (3.78%). The overall live sperms were significantly (P less than 0.01) higher during post-supplementation (73.33±0.91%) than the pre-supplementation (63.53±1.03%). It may be concluded that supplementation of 100 ppm of zinc propionate in the diet of Kankrej bulls improved semen quality in terms of quantitative and qualitative characteristics of semen.

Authors: Rani Marlon Brando , Kayang Highland
Published: December 2022

Background: The rhizosphere contains many beneficial microorganisms which have a positive action on plant growth and development. In both natural and controlled ecosystems, beneficial plant-associated bacteria play a key role in supporting and increasing plant health and growth. Methods: In this study, plant growth promoting Bacillus isolates associated with the rhizosphere of black pepper (Piper nigrum) were selected and used for bioassay experiments for the host plant as well as for two test plants viz. French bean (Phaseolus vulgaris) and Pea plant (Pisum sativum). Result: This investigation revealed that the isolates chosen for the study exert a positive effect on the growth of inoculated black pepper plants and the test plants as compared to uninoculated control. Molecular identification of the selected isolates was done based on 16S rRNA gene analysis. All the four isolates exerted a considerable influence on the growth of black pepper cuttings and there is a significant increase in the shoot height and root length compared to untreated cuttings. Seed bacterization of the two test plants resulted in the increment of plant height and a heavier fresh weight and dry weight when compared to control plants. Based on these findings, it is evident that the isolates can be employed to enhance the growth not only of black pepper but of the test plants as well. Hence, according to this study, the selected isolates could be used as plant growth-promoting inoculants to attain the desired results of stem cuttings and seed bacterization.
Evaluation of the Effectiveness of Realistic Mathematics Education: Meta-Thematic Analysis / Gerçekçi Matematik Eğitiminin Etkililiğinin Değerlendirilmesi: Meta-Tematik Analiz
Authors: ELALDI Şenel
Published: December 2022

This study was aimed to determine the effectiveness of the Realistic Mathematics Education (RME) used in mathematics teaching. For this aim, studies including participant views on the use of RME were examined in accordance with the PRISMA flow chart and in line with the inclusion criteria determined by the researcher. These criteria were determined as “studies involving the RME application in the field of mathematics, studies conducted between 2012-2022 (last ten years), studies containing qualitative participant views, and studies published in Turkish or English”. A total of 146 studies reached were evaluated according to these criteria, and the remaining 24 studies were included in the meta-thematic analysis. The data on the examination of the use of RME were obtained by the document analysis and analyzed by the content analysis through the use of the Maxqda-11 qualitative data analysis program. The themes that emerged from the analysis were: contribution to the delivery of course, making connections with daily life, contribution to the attitude towards mathematics and contribution to thinking skills. These themes and codes were interpreted separately. In addition, direct quotations from the sources were included to support the presentation of the relevant themes and codes. Analysis results showed that RME has contributed positively to math teaching in many ways. On the other hand, the negative contribution of RME to math attitude emerged with codes such as inefficient use of time, noise, negative group synergy and intra-group conflicts. It is suggested to include more RME practices in order to adopt the principle of "mathematics for all" on Freudenthal's discourse, to develop a positive attitude towards mathematics and to associate it with real life.

Ulusal kimlik özünde sosyal olarak inşa edilmiş bir fenomendir. Ulus bilinci bir toplum tarafından paylaşılan bir ulusal kimlik duygusunu ifade eder, bu bakımdan bireyin kolektif farkındalık düzeyini gösterir. Paylaşılan inançlar, ortak değerler ve müşterek beklentiler ulus bilincinin gelişmesine katkı sağlayan sosyalizasyon araçlarıdır. Ulus bilinci halkların kontrol ve denetim altına alınmaları ile değil, bilakis, değerli birer varlık olarak yüceltilmeleri ile oluşur. Yalnızca belirli bir gruba ait olma bilinci, grup hakkında olumlu duygular uyandırır ve diğer grup üyeleri bazen kişisel olarak bilinmese bile, o grup adına hareket etme eğilimine yol açar. Ulusal kimlik, bir kendi kendini kategorizasyon sürecidir. Bu süreç, hem kişinin ulusuyla özdeşleşme, hem de diğer uluslarla farklılaşmasını içerir. Bu çalışmada ulusal kimlik, ulus bilinci ve gelişimi, kültürel izomorfizm, müşterek ve kolektif ulus bilincinin tesisi üzerine özgür ve çoğulcu bir toplum paradigması bağlamında bir inceleme gerçekleştirilmektedir.

Araştırmada ilk olarak ölçüm değişmezliği test edilerek genel modelin güçlü değişmezliğe, işyeri sosyal cesaret ölçeğinin ise katı değişmezliğe sahip olduğu tespit edilmiştir. Kadın ve erkekler üzerinde yapılan bağımsız gruplar t testi, erkeklerin kadınlara göre daha yüksek sosyal cesaret ve etkileşim adaleti algısı olduğunu göstermektedir. En çok olabilirlik yöntemi ile gerçekleştirilen çoklu grup yapısal model analizi etkileşim adaletinin işyeri sosyal cesaretini anlamlı ve pozitif olarak yordadığını göstermektedir. Bu etki kadınlarda erkeklere göre daha fazladır.

Published: December 2022

Bu çalışma proaktif kişiliğin iş çıktıları üzerindeki etkisinde lider-üye etkileşiminin aracı etkisini belirlemeyi amaçlamaktadır. Literatürde çoğunlukla proaktif kişiliğin olumlu iş çıktılarına etkileri incelenmiştir. Çevresini etkilemek için inisiyatif kullanma eğiliminde olan proaktif kişiliğe sahip çalışanlar, olumsuzluklardan daha az proaktif özelliklere sahip çalışanlara göre daha yüksek oranda etkilenecektir. Bu bağlamda proaktif kişilik özelliklerine sahip çalışanların örgütün etkinliğine katkı sunmalarında ve olumsuzluklardan daha az etkilenmelerinde liderlerin rolü, lider ile takipçilerin uyumu ve lider-üye etkileşiminin kalitesi önemli bir etkendir. Proaktif kişiliğin olumsuz iş çıktıları üzerinde etkisi kapsamında işten ayrılma niyeti ile tükenmişlik alt boyutlarından duygusal tükenme, duyarsızlaşma ve kişisel başarı hissi azalması alt boyutları bu çalışmada değerlendirilmiştir. Araştırma kapsamında Ankara’da bir özel güvenlik firmasında çalışan 116 özel güvenlik personeline olasılığa dayalı olmayan kolayda örnekleme yöntemi ile anket uygulanmıştır. Anket sonuçları SPSS 24 ve AMOS 24 programları kullanılarak analiz edilmiştir. Yapılan analiz sonucunda proaktif kişilik ile lider-üye etkileşimi arasında pozitif etki varken, proaktif kişiliğin ve lider-üye etkileşiminin kişisel başarı hissi azalması üzerinde negatif etkisi tespit edilmiştir. Bununla birlikte proaktif kişiliğin kişisel başarı hissi azalması alt boyutu üzerindeki etkisinde lider-üye etkileşiminin kısmi aracılık etkisi tespit edilmiştir.

Günümüz dünyasında örgütler, başarılı oldukları sürece, büyümeye ve varlıklarını sürdürmeye devam edebilmektedirler. Örgütleri daha başarılı hale getirmesi beklenen liderler, bu açıdan önemli görülmektedir. Bu bağlamda davranışları ve söylemleri ile takipçilerini etkileyerek onlara yol gösteren ve örgütsel başarıyı yakalayan liderlerin yanında, çalışanlarının motivasyonlarını düşüren, onları değersizleştiren ve başarısızlığa sürükleyen liderler de vardır. Liderlerde görülen bu olumsuz davranışlar, onların baskıladıkları ve kontrol altında tuttukları karanlık taraflarının ortaya çıkmasıyla görülmektedir. Lider, karanlık tarafının ortaya çıkmasıyla örgütü ve çalışanları derinden etkileyen olumsuz ve yıkıcı davranışlar sergilemektedir. Bu olumsuz davranışların başında, karanlık liderlik ve kayırmacılık gelmektedir. Bu çalışmanın amacı, karanlık liderliğin kayırmacılık üzerine etkisini tekstil sektöründeki çalışanların a,lgıları bağlamında araştırmaktır. Araştırmanın örneklemi, Malatya ilinde I. ve II. Organize Sanayi Bölgelerindeki orta ve büyük ölçekli tekstil işletmelerinin çalışanlarından seçilmiştir. Araştırma verilerinin toplanmasında anket tekniği kullanılmış olup 513 katılımcıya ait anket değerlendirmeye alınmıştır. Araştırmanın sonuçlarına göre tekstil sektöründeki çalışanların algıları bağlamında karanlık liderliğin kayırmacılık üzerinde anlamlı bir etkisi olduğu saptanmıştır. Erişilen bulguların işletme yöneticilerine ve yazındaki kuramsal çalışmalara katkı sağlayabileceği düşünülmektedir.

Published: December 2022

—This paper presents the results of 3D inversion of magnetovariational tippers obtained at the Cape Schmidt observatory via digital processing of geomagnetic variation records performed by the MAGDAS-I magnetometer. 3D tipper frequency inversion is carried out using the ModEM software. The result is horizontal and vertical sections in the coastal strip of the Chukchi Sea in a spatial region with a dimension of 300 × 300 × 200 km along the X, Y, and Z axes, respectively. The geoelectric section of the investigated region contains both surface and deep conductive blocks located at different azimuths relative to a measurement point. The surface conductive anomaly near the observatory with a resistivity of ≈3 Ohm·m is located in the southeast direction at depths of a few hundred meters. The other conducting inhomogeneity is larger and located in the same direction, but at a distance of about 25–30 km and depths of 4–16 km. The resistivity of its central region at a depth of 8 km is equal to 1 Ohm·m. From the side of the South Chukchi Depression, there is an inclined conductive block in the Chukchi Sea, located closer to the coast to the bottom of the Earth’s crust, and the maximum resistivity of this block in the central part at a depth of 20 km is equal to ≈7 Ohm·m. The most noticeable feature of the section is a massive upper-mantle conductive block under the continent at depths of 50–120 km with a resistivity of 3–4 Ohm·m in the central part at depths of 70–85 km. Deeper into the continent, the block is slightly inclined to the southeast. There are visible conductive regions that connect this block with upstream conductive formations. The epicenters of weak crustal earthquakes recorded in the region are located above the northwestern marginal part of the upper-mantle block, including its central region. Possible mechanisms of high electrical conductivity of anomalous blocks are discussed.

Localisation of impacted teeth is essential for surgical and orthodontic management. The study objective was to evaluate the prevalence and type of tooth impaction in the jaws using cone beam computed tomography (CBCT). The CBCT records of subjects between 2018 and 2020 were retrieved from our institution archives and examined by two oral radiologists. A total of 760 CBCT scans were evaluated, of which 140 (18.4%) scans had impacted teeth. From the 140 CBCT scans, 216 impacted teeth were identified. Maximum impactions were in the age group of 21–30 years. Third molars were the most commonly impacted teeth (66.2%), followed by canines (23.6%), supernumerary teeth (4.6%), premolars (3.2%), incisors (1.4%), and second molars (0.9%). Among the impacted canines, 53% were buccally impacted, 43% were palatally impacted and other impactions were 4%. Among the third molars, mesioangular impactions were the most frequent (41.2%), followed by horizontal (28%), vertical (16.7%) and distoangular impaction (4.1%). The most frequently impacted teeth were the third molars, followed by canines. Canine impactions were more frequent in the maxilla, while third molar impactions were thrice as common in the mandible compared to the maxilla. Mesioangular third molar impactions were the commonest, followed by horizontal, vertical and distoangular.
