Relevance. It is known that endodontically treated teeth have a lower survival rate compared to vital teeth. This is due both to changes in the hard tissues of the tooth, and to the use of inadequate technologies for their restoration. Therefore, the methods of restoration of such teeth are very relevant. But their application should be conditioned by their scientific substantiation using fundamental research methods, which determined the relevance of this study.

Material and methods. The study of the structural and functional characteristics of the restoration was carried out by scanning electron microscopy in the area of the restoration border, the border of the material-pin insert, the ledge area and the surface of the restoration material. For this purpose, 60 periodontal removed teeth with an IROPZ index of 0.8 or more were used, of which 120 restoration samples were made from the standard form of the composite and 120 restorations from the core-composite using a fiber-optic pin in both groups.

Results and discussion. In the course of the study, it was found that the data obtained in the study of the morphology of the restoration in group No. 1 indicate insufficient adaptive properties of the traditional form of the composite (porosity, cohesive fractures, violation of the marginal fit); The results of SEM testify to the advantages of the core-composite, which has a homogeneous, micro-rough, adhesive surface free from technical impurities, suitable for the use of all currently used methods of fixing an orthopedic structure.

Authors: Usubova N. R.
Published: April 2022

Monolithic restorations are becoming increasingly popular due to the reduction of technical complications. The upper incisors are the most affected teeth due to their location and protrusion.

Aim. To determine the strength on models of incisors restored with monolithic crowns made of aluminum oxide and lithium disilicate.

Materials and methods. The finite element method created 2 models for the upper incisor. In the mesh model with an aluminum oxide monocrown, the number of nodes was 130185, the number of elements was 90934. In a mesh model with a lithium dioxide monocrown, the number of nodes was 130,000, the number of elements was 96,000. 3D models were built and analyzed in the ANSYS environment.

Results. In the alumina model, when loaded in the medial side (X), the horizontal and vertical forces were 0, in the vestibular side, the vertical force was -190 N, and the horizontal was 0, in the direction of the main axis of the tooth, the horizontal force was 15. In the lithium disilicate model, the maximum stresses mvM in dentin were 13.7 MPa, in cement – 18.5 MPa, in the crown – 61.8 MPa. Tensile, shear, and compression contact stresses at the adhesive interface between cement and dentin around the lithium crown and post were 11.9 MPa, 3.5 MPa, and 17.2 MPa, respectively.

Conclusions. A finite element analysis of an incisive endocrown based on aluminum oxide and lithium disilicate was successfully performed. Based on these results, an endocrown can be considered as an aesthetic and clinically feasible restorative approach for endodontic treatment of central incisors.

One of the express diagnostic methods is a crystallographic study of the oral fluid of this category of patients. Based on the quantitative and qualitative criteria of saliva obtained by the method of wedge dehydration, it is possible to non-invasively assess the effectiveness of the therapy and timely correct the prescribed treatment.

Aim. To conduct a comparative analysis of the crystallograms of the oral fluid in the dynamics of the treatment of patients with pathology of the oral mucosa.

Materials and methods. 90 patients were examined with a diagnosis of K12.00 aphthous stomatitis (small), chronic recurrent aphthous stomatitis (mild form). All patients were divided into 3 groups according to the methods of therapy 1:1:1 according to the principle of randomization. To assess the state of the oral fluid of patients with aphthous stomatitis against the background of various methods of treatment, the method of wedge-shaped dehydration was used, where the transition of a drying biological fluid into a solid state leads to a certain static order that can be observed and studied. Saliva was used as the material for the study.

Results. A qualitative analysis of the crystallograms revealed various types of structures with inclusions of bent prismatic crystals. Prismatic, fragmentary, curved, X-shaped, skeletal types of crystals were found throughout the entire field of view. At the same time, there was no clear structured picture as a result of a violation of the normal crystallization process.

Conclusion. There is a clear need for further research into the molecular etiopathogenesis of these conditions, which should allow the identification of more specific molecular targets for the development of diagnostic tests and therapeutic intervention. Based on the data obtained, the wedge dehydration method used for crystallographic examination of the oral fluid objectively reflects the state of the oral mucosa and can be used as an additional non-invasive method for diagnosing inflammatory and destructive diseases of the oral mucosa, as well as for correcting the treatment plan and monitoring the results of therapy.

Published: April 2022

The medical literature speaks about the influence of the oral cavity environment on the orthodontic archwires containing nickel (Ni) in their structure, causing corrosion of the archwires with the release of nickel ions into the patient’s oral fluids leading to its ingestion. If the nickel content in the body exceeds certain proportions, it is considered hazardous and can cause negative effects on the patient’s body.

Aim. To assess whether the clinical application of round thermoactive nickel-titanium (NiTi) archwires will risk increasing the concentration of (Ni) ions in the patient’s oral fluids within first two months of the orthodontic treatment.

Materials and methods. The Research was conducted on 17 patients, aged 14 to 27 years, fixed metallic orthodontic appliances were used for treatment. Using an atomic absorption spectrophotometer, oral fluid Samples were analyzed to determine the preliminary рН. Oral fluid samples were gathered from all participants of the study groups during different periods of time, observation was as follows: Before installation of fixed appliances, immediately after fixing the braces and tying up the thermoactive NiTi archwires, in 7 days, one month and two months after fixation.

Results. There were no statistically significant differences in concentration of (Ni) ions in first two months of treatment. However, in (25 %) of samples taken from patients in 1-2 months after the beginning of treatment a small increase in concentration of Ni ions (by 7,5 %) was observed.

Conclusions. It is improbable that a thermoactive NiTi archwire has a significant additional Ni load for patients undergoing orthodontic treatment.

An Equivariant Quantum Pieri Rule for the Grassmannian on Cylindric Shapes
Authors: Anna Bertiger  , Dorian Ehrlich  , Milićević Elizabeth , Kaisa Taipale
Published: April 2022

The quantum cohomology ring of the Grassmannian is determined by the quantum Pieri rule for multiplying by Schubert classes indexed by row or column-shaped partitions. We provide a direct equivariant generalization of Postnikov's quantum Pieri rule for the Grassmannian in terms of cylindric shapes, complementing related work of Gorbounov and Korff in quantum integrable systems. The equivariant terms in our Graham-positive rule simply encode the positions of all possible addable boxes within one cylindric skew diagram. As such, unlike the earlier equivariant quantum Pieri rule of Huang and Li and known equivariant quantum Littlewood-Richardson rules, our formula does not require any calculations in a different Grassmannian or two-step flag variety.

Рассмотрено понятие прослеживаемости в законодательстве России, Евросоюза и США, различных стандартах. Главной проблемой при отслеживании прослеживаемости хлебобулочных изделий авторы считают сложности учета движения зернового сырья от поля до хлебопекарного производства. Проведен анализ зарубежного опыта в этой сфере, который позволяет сделать вывод, что в условиях крупного производства существующие методы пока не дают возможности решить эту задачу. Приведены примеры прослеживаемости хлебобулочных изделий в случае небольших хлебопекарных бизнесов в ограниченном региональном масштабе с использованием современных цифровых технологий. Анализ запросов в сети Интернет показывает растущий интерес российских потребителей к прослеживаемости продовольствия. Авторы на основе выполненного НИИ хлебопекарной промышленности (г. Москва) исследования делают вывод, что в ближайшей перспективе прослеживаемость может стать эффективным инструментом маркетинга, прежде всего, ориентированного на молодых потребителей, озабоченных проблемами устойчивого развития.

Статья посвящена исследованию физико-химических показателей качества муки ржаной обдирной и ее пенообразующей способности. Пенообразующая способность ржаной муки не нормируется в ГОСТе, но является важным показателем, отражающим технологические свойства муки в закваске, поскольку повышенное пенообразование отрицательно сказывается на работе насосов, дозаторов и расходе закваски при замесе теста. Исследования проводились в Санкт-Петербургском филиале ФГАНУ «НИИХП». Объектами исследования являлись три партии муки ржаной обдирной трех российских производителей из разных регионов. Физико-химические показатели качества муки определяли общепринятыми в хлебопекарной отрасли методами. Определение пенообразующей способности и стойкости пены проводили по методике, предложенной отделом растительных белков и биотехнологии ВНИИЖ. В результате исследований установлены физико-химические показатели качества трех проб муки. Установлено, что все пробы муки имели довольно высокое значение показателя ЧП, а одна проба № 1 была отнесена к муке с пониженной ферментативной активностью. Технологические испытания ржаной муки при выведении жидкой закваски влажностью 70% показали, что все закваски существенно увеличивались в объеме (в 0,9–2,5 раза), причем закваски из муки первой и третьей проб давали стойкую неоседающую пену. Установлено, что увеличение содержания белка в муке ржаной обдирной привело к повышенной пенообразующей способности в водно-мучных суспензиях, а также оказало влияние на стойкость пены. Показатели качества муки ржаной обдирной, регламентируемые ГОСТом, не отражают в полной мере технологические свойства муки, проявляющиеся в процессе приготовления заквасок.

Economic and social development of both the country as a whole and its individual regions is impossible without maintaining the required level of development and technical condition of the road network. This also applies directly to agricultural producers. Despite the fact that considerable funds are allocated for the construction and repair of roads, the service life of roads often does not meet the standard values. One of the reasons for the low service life of road structures are design errors related to the lack of data on the thermal conductivity of road construction materials, seasonal freezing of the roadbed, which together with unsatisfactory soil and hydrological conditions contribute to significant deformations. One of the main problems in the road industry at present is insufficient consideration of soil and hydrological conditions of the area, which are estimated approximately from topographic maps and materials of old documents or, at best, from the results of reconnaissance surveys. At the same time, it is often difficult to provide the required load-bearing capacity and frost resistance of road structures with an unsuccessfully selected, even short route, since when designing the roadbed, soil and hydrological conditions are secondary, and the choice of the route location is primary. It is well known effect when periodic freezing and thawing of the road surface leads to the appearance of alternating stresses, which significantly accelerate the destruction of the road surface and sometimes the foundation. A thorough understanding of the processes of freezing and thawing of the roadbed makes it possible to avoid design errors, and the significant financial losses associated with them, in the construction of long-distance forest roads. The article presents the features of processes occurring in the layers of road construction during seasonal freezing. Hypotheses about the processes of moisture migration in seasonally frozen soils, the influence of heat capacity and thermal conductivity of road construction materials on the course of these processes, as well as methods for modeling processes occurring in road structures under the influence of natural and climatic conditions are considered, and the results of the field experimental studies are presented.
Formation of Coaxial Fields of Residual Stresses in the Circular Saw Blade

Published: April 2022

The working tool of machines with circular cutting units is a circular saw, the condition of which largely determines the quality of material processing. Circular saw blades in the process of operation are subjected to a complex effect of force and temperature factors that cause elongation and deformation of the saw blade, and the occurrence of internal stresses that take it out of the flat form of elastic balance and reduce the tool’s performance. The ability of saws to resist these factors is determined by the rigidity and stability of the saw blade. It is customary to consider a circular saw blade consisting of three zones: peripheral, middle and central. The middle part has the greatest influence on the stability of the saw blade. Initially, after manufacturing, the saw blade has a flat shape of balance, which can be disturbed by any external impact on the saw during the cutting process. The balance disturbance causes the blade and the cutting edge of the saw to deviate from the initial operating condition and reduce the accuracy and quality of wood processing. In order to prevent the influence of external forces, coaxial zones of plastic deformation of a certain width are formed in the middle part of the blade. In this case, under the influence of the created stresses, the effect of web tension appears. In world practice, two methods of forming such zones are used: forging and rolling. The creation of normalized stresses in the circular saw blade is carried out by local mechanical contact action of the working body of the saw tool on the steel saw blade in certain places of the middle zone. Compressive stresses compensating the forces of centrifugal acceleration, the thermal heating of individual zones of the saw blade, the external longitudinal and transverse bending forces that occur in the blade during wood processing are formed in the treated annular zones. The considered methods for creating annular zones of plastic deformation fields involving mechanical action on the saw blade have significant drawbacks, the elimination of which requires fundamentally new technical solutions. It is proposed to form coaxial fields of residual stresses of the saw blade by thermoplastic action consisting in creation of normalized residual stresses in the saw blade by concentrated thermal action on local annular zones coaxially located along the saw blade for the entire thickness of the saw. The formation of coaxial circular fields of residual stresses in the circular saw blade is simulated. The considered method of saw preparation will increase its stability in the process of operation.
Features of the Horizontal Structure of Forests of Spruce Formations in the European Taiga of Russia
Authors:   Institute of Forest Science RAS, Storozhenko Vladimir G.
Published: April 2022

The article highlights the issues of studying the structure of indigenous forests of different ages as a model of sustainable forest formations. The research purpose is to study the patterns of horizontal structure formation of indigenous virgin spruce forests of the northern, middle and southern taiga subzones of European Russia. We consider the nature of the horizontal structure as one of the most important signs of sustainability of forest communities developed over the evolution. Indigenous virgin spruce forests in each of the taiga subzones of European Russia were adopted as research objects: spruce forests of the Severodvinsk forestry of the Arkhangelsk region in the northern taiga subzone; spruce forests of the Vepsky forest reserve in the middle taiga subzone; spruce forests of the Central Forest Nature Reserve in the southern taiga subzone. Sample plots were laid out in biogeocenoses, where we studied the age, horizontal, and pathological characteristics of spruce forests. Continuous tree drilling was carried out to determine the age of trees and their infestation by wood-destroying fungi of the biotrophic complex. The mosaics of age generations were identified on the plans of sample plots; the area of each of them, the volume of trees in the mosaics and the homogeneity by age, and the amount of natural regeneration were determined. Indigenous spruce fir forests of the taiga of European Russia have a different age structure with a different number of age generations in the age series and various dynamic indicators of biogeocenoses. All of them have a mosaic arrangement of trees grouped by different age generations, growing in different sized areas and distinguished by an unequal degree of homogeneity in terms of age. This defines a complex age horizontal and vertical structure of biogeocenoses; the most important condition for sustainability of forest communities. Accounting of spruce natural regeneration showed significant differences in the number of undergrowth in spruce forests of different taiga subzones, which refers to a variety of horizontal structures of such forests. The ratio of the number of spruce undergrowth growing on decaying trunks of woody debris and on the ground is as follows: the number of 0.5 m high undergrowth in both growing conditions is almost equal, the number of over 3 m high undergrowth on deadwood trunks is less compared to the number of undergrowth of this height category on the ground.
The Potential Impact of Climate Change on the Distribution of Norway Spruce (Picea abies Karst.) in Bosnia and Herzegovina

Published: April 2022

As forests in Bosnia and Herzegovina cover 2,904,600 ha or 56.7 % of its total area, and since the meteorological data analysis for the period 1961–2014 shows that the mean annual temperature maintains a continuous rise, сlose attention should be paid to these fragile ecosystems. It is important to note that one of the most economically valuable species for forestry in Bosnia and Herzegovina, Norway spruce, is particularly endangered due to its very low drought resistance and spread of various diseases. Comparing the last climate sequence (1991–2019) with the previous one (1961–1990) we found that the spruce-inhabited areas showed an average increase in the values of the Forest Aridity Index of 0.929. As for the Ellenberg’s climate quotient, it is noticeable that climate change is not as strong as in the case of the Forest Aridity Index. Based on projections for the mid- (2041–2070) and late-century (2071–2100) under the RCP 4.5, there will be no change that is likely to significantly affect the distribution of spruce. The predicted rates of decline and altitudinal shifts of favorable habitats are negligible. On the contrary, projections under the RCP 8.5 predict a significant reduction of suitable habitats, both for the existing range of Norway spruce and the entire territory of Bosnia and Herzegovina. Particularly, late-century projection under the RCP 8.5 predicts an almost complete reduction of suitable habitats, while small areas of suitable habitats at higher elevations will remain intact.

A conger eel (Anguilliformes, Congridae) is described from the lower Lutetian concretionary nodules of the Lillebælt Clay Formation exposed at Trelde Næs, eastern Jutland, based on two partially complete articulated cranial skeletons. One of the cranial specimens exhibits an otolith void from which a cast was taken, used by Schwarzhans (2007) to describe the extinct Pseudoxenomystax treldeensis, which is placed herein within the new genus Smithconger gen. nov. Smithconger treldeensis (Schwarzhans, 2007) is characterized by well-developed lateral processes on the frontals, supraoccipital crest absent, sphenotic spine rather large, anteriorly pointed and exposed on the flattened surface of the skull roof, otic bullae considerably reduced, maxilla almost straight and distally pointed, maxillary and dentary teeth numerous and arranged in multiple rows, dentary with slightly convex ventral profile, opercle with smooth posterior margin and subopercle short. The otoliths of Smithconger treldeensis show high dorsal rim, broad and deep dorsal depression, no ventral furrow, sulcus straight, shallow, centrally positioned with anteriorly reduced colliculum, and ostial channel at anterior tip of colliculum short, not reaching the predorsal rim. The otolith-based species Bathycongrus waihaoensis Schwarzhans, 2019 from the Kaiatan (Bartonian/Priabonian) of New Zealand is also assigned to the genus Smithconger. Smithconger is tentatively referred to the congrid subfamily Congrinae due to the lack of hypohyals in the hyoid bar. This new Eocene genus of conger eel shows a certain degree of similarity with the extant Bassanago. The diversity and relationships of other Eocene congrids is also briefly discussed.
Informatization as an attribute of the information society: from retrospection to modern reflection
Authors: DANILYAN O. , DZOBAN O.
Published: April 2022

It is argued that the process of informatization of society should include at least three complementary elements: mediatization as a process of improving the means of working with information, computerization as a process of improving the means of information processing and intellectualization as a process of improving human knowledge and abilities to generate and perceive information. The ambiguity of the social consequences of informatization is proven. It is argued that informatization in itself is not a guarantee of success and social progress, it must be organically integrated into the overall system of social activities.

Metagraphs for ontological engineering of complex systems
Authors:   Inter-state Educational Institution of Higher Education ", Misnik Anton Е. ,   Belarusian-Russian University"
Published: April 2022

The article deals with the issues of ontological engineering of complex systems. Ontological engineering includes the processes of designing and building ontologies, technologically combining object-oriented and structural analysis. Ontological engineering aims to ensure the adoption of high-quality management decisions by increasing the level of integration of the necessary information, improving search capabilities in databases and knowledge bases, providing the possibility of joint processing of knowledge based on a single semantic description of the knowledge space. This process is carried out within the framework of the proposed approach to managing complex systems. The ontology obtained as a result of engineering is subject to the requirements of convenience and flexibility, which is necessary for modeling system processes and ensuring the functioning of information and analytical processes in a complex system. The application of ordinary graphs, hypergraphs and metagraphs in ontological engineering is described. The use of metagraphs in the construction of hierarchical ontologies is substantiated. Metagraphs are considered as the basis for building an applied ontology of a complex system. A modification of the metagraph is proposed, which makes it possible to include events and data processing methods in the ontology. Such a modification integrates the process component into the ontological model of the system as an integral part of it, which makes it possible to flexibly and with less time to form process models based on the metagraph subgraphs of the general ontological model. An approach and an example of the implementation of the software-instrumental environment of ontological engineering and further construction of models of processes of a complex system are described. The technology used to implement the ontology in the PostgreSQL database management system and the database structure for storing the ontology are described

Optical spectral methods in the ultraviolet and visible regions can be used to develop transformer oil control technologies based on deep learning neural network models. The aim of the research is to identify informative spectral ranges of luminescent diagnostics for the automation system for monitoring the characteristics and parameters of transformer oil using deep learning neural networks. Measurements of the spectral characteristics of pure and spent transformer oil in the range of 180-700 nm were carried out on a diffraction spectrofluorimeter "Fluorat-02-Panorama". A qualitative and quantitative difference in the excitation spectra has been established: for waste oil, the spectra are shifted to the right and reduced by about four times to the maximum. The excitation maxima are located at wavelengths of 300, 322, 370 nm for pure and 388, 416 and 486 nm for waste oil. The photoluminescence spectra of pure oil at 300 nm excitation are a superposition of at least three curves, the largest of which has a maximum at 382 nm. For excitation of 370 nm, the spectrum is significantly wider and has maxima at wavelengths of 387, 405, 433-439 and 475-479 nm. The photoluminescence spectra of used oil are several times lower and have maxima at 446, 483 and 520-540 nm. The established excitation and luminescence ranges will be used when creating a methodology and installing quality control parameters of transformer oil during its operation. A deep learning neural network model based on the use of a self-organizing Kohonen map was also developed, which made it possible to predict the spectral characteristics of excitation based on the photoluminescence flow of transformer oil and, as a result, to determine the efficiency of the described method in industry through a decision-making system.

The article is devoted to the issues of modeling and designing information-analytical processes corresponding to the production and technological processes at the enterprise. In the modern conditions of the functioning of the market, the enterprise faces important tasks of embedding in global supply chains, responding to an increase in the need for personalized products and, most importantly, reducing costs and improving product quality. In addition to solving these problems, the enterprise has to deal with such problems as: overproduction, waiting and wasted time, defects and marriage. Despite the fact that economic efficiency is put at the forefront, in order to ensure the sustainable development of an enterprise, it is necessary the criteria of environmental friendliness, accident-free operation and social efficiency. Enterprises, whose competitive advantages are flexibility and response speed to market needs, require tools for the operational management of production and technological processes. For effective functioning within a complex system, planning and implementation of production and technological processes must be supported by appropriate information-analytical processes that provide the collection and analysis of information, as well as modeling and making control decisions for the production and technological process. Production management is carried out in the form of strategic, tactical and operational planning, which puts forward additional requirements for modeling tools and management decision support. A variety of neuro-fuzzy Petri nets with temporal fuzzy neurons is proposed. An example of building a model of the production process and the corresponding information-analytical processes is considered. The developed specialized software for modeling production and technological processes and the implementation of information- analytical processes, including modules for forming an ontological model of a complex system and processes, obtaining data, a neural network supervisor, building a model of a production- technological process and corresponding information-analytical processes using the mechanism constructors based on neuro-fuzzy temporal Petri nets is considered.

One of the most often used folk medicines is Sesbania grandiflora, better known as the Agati or Hummingbird tree. Anemia, bacterial infections, TB, and other illnesses can be treated with the plant's pharmacological properties. Agati's anticancer and hepatoprotective properties are attributable to the presence of phytochemical ingredients. Sesbania grandiflora's therapeutic characteristics are the topic of this article. Normal psychological functioning and behavioural patterns are disrupted by dementia. One to four percent of the world's population over the age of 65 is affected by dementia, which is a neurological disease. Dementia is caused by a number of different factors. Because dementia is more common in those who have cardiovascular and neurodegenerative conditions (such hypertension, hypercholesterolemia, diabetes and cerebral ischemia), these people are more likely to develop it. In addition to alcohol and tobacco use, these conditions are exacerbated. Alzheimer's dementia, vascular dementia, frontotemporal dementia, semantic dementia, and dementia with Lewy bodies are the most frequent kinds of dementia. As we get older, Alzheimer's and Lewy body dementias become more common. It is the second most frequent kind of dementia after Alzheimer's disease (AD), and it can be caused by long-term cardiovascular disease (CVD). Deterioration in semantic memory is a hallmark of semantic dementia (knowledge of objects, people, concepts and words). synuclein aggregation in Lewy body dementia (LBD) impairs neuronal growth and has a significant impact on the disease aetiology. Alzheimer's disease, Parkinson's disease, schizophrenia, and other neurodegenerative diseases all have a strong genetic component, as do frontotemporal dementia and Alzheimer's disease. An important part of this study is the discussion of the role of glutathione (GSH), SOD, GPx, and Catalase (Cat) during oxidative stress and the link between mitochondrial dysfunction and many disorders, including dementia. The purpose of this review is to examine the types, risk factors, and underlying mechanisms of dementia, as well as new therapy techniques, in order to maximise the chances of finding new and effective therapeutic strategies

The Yamburg oil and gas condensate field, like many northwestern fields, is at the final stage of production. The consequence is that the large amount of formation water in the inflow may accumulate in particular in well bottom hole. The response surface analysis is used as a new technique for gaining detailed understanding of the relationships between combinations of two predictor variables and a result variable. This approach was applied to the Yamburg field in order to estimate the time of gas-water contact lift considering the lithological characteristics of the reservoirs. The results of the predicted gas-water contact time were compared to the expected gas-water contact time, the data of which were considered for the study. Using the parameters of the model as well as the three-dimensional response surface, which was built to facilitate and improve the interpretation of the results, it was possible to predict the gas-water contact time under certain conditions.
Effects of Variable Thermal Conductivity and Grashof Number on Non-Darcian Natural Convection Flow of Viscoelastic Fluids with Non Linear Radiation and Dissipations
Authors: Karem Mahmoud Ewis
Published: April 2022

Effects of variable thermal conductivity, porosity and Grashof number on natural convection of viscoelastic fluid flow and heat transfer are studied and discussed. The nonlinear radiation and dissipations are taken into consideration. The fluid flows through non-Darcy porous medium which lies between two heated vertical plates that are kept at constant, but different, temperatures. High order accurate finite difference schemes are introduced to solve the governing equations. The coupled nonlinear differential equations are linearized and iterations are used to approximate that linearized terms. The finite difference method transforms the coupled linearized differential (momentum and energy) equations to a linear system of algebraic equations. An error analysis is introduced by refinement of mesh size and comparisons with available previous results. Effects of fluid and heat parameters on the velocity field, temperature, skin friction factor and Nusselt number are tabulated and plotted. The present results and comparisons show that the numerical solution is of excellent agreement with previous analytical and numerical solution.

Polarization Tensor (PT) has been widely used in some of the applications of electric and electromagnetic such as electrical imaging, metal detection and electrosensing fish. Furthermore, in these applications, polarization tensors can capture significant information such as material, shape and orientation about the related objects (medical images in electrical imaging or metallic target in metal detection). Some physical information about the unknown objects can then be characterized from the given first order polarization tensor that representing the object. Therefore, it is beneficial to determine an ellipsoid based on the given first order polarization tensor due to the possible similarities between the ellipsoid and the unknown object. The main objective of this study is to present a method in order to determine the semi axes of the spheroid, which is an ellipsoid with two identical axes. The method is an extension of the previous method which is only applicable to two types of spheroid. Using the rotation of the first order polarization tensor, we will show that this extended method can be used to determine all semi axes for any types of spheroid, depending on the given first order PT. After that, some numerical examples are provided specifically to compare between the first order PT for the spheroid with the given first order PT for verifying the results obtained. It is expected that the computed first order PT for the spheroid will be almost similar to the given first order PT.
