Published: November 2021

Betta (Betta sp.) is an anabantidae fish with sexual development that can be directed at the embryonic and larval stages. One way to direct the sex development of these fish is by using hormone therapy using natural ingredients. Coconut water is one of the natural ingredients that can be used because it contains high potassium. This potassium can convert cholesterol in fish body tissue to pregnenolone which will affect the increase in testosterone production. This study aims to determine the best dose and age group in directing the sex of Betta fish experimentally using a randomized block design (RBD) with 4 treatments and 3 replications. The immersion treatment of larvae in the age group of 3 days, 5 days, and 7 days for 15 hours with a dose of 0%, 10%, 20%, and 30% coconut water was carried out in a 3 L jar containing 30 larvae. The results showed that coconut water was able to influence the increase in the percentage of male betta fish (P <0.05) with the highest value at a dose of 30% as much as 86.26 ± 8.34% and the 3 day larvae age group of 72.78 ± 16.03, and have a different effect on other treatments. In addition, the survival calculated after immersion shows a value of 100%, meaning that coconut water does not have a harmful effect on fish. Based on the results of this study, the best treatment for directing the sex of betta fish is a dose of 30% coconut water with the 3 day age group

Authors: Gupta Nidhi , Taran Shachi Jain , Gupta Surabhi , Arora Kewal kishore
Published: November 2021

Introduction: Nearly 60-80% of the term and preterm neonates are affected due to rise in bilirubin levels during early postnatal days, and causes readmission of the neonate sometimes with severe jaundice, which can be reduced if neonatal hyperbilirubinemia can be predicted early. The study was conducted to evaluate the predictive values of cord blood albumin and bilirubin for neonatal hyperbilirubinemia and to evaluate the better predictor between them.
Method:  In this hospital based observational study, 152 healthy term newborns with birth weight more than 2.5 kg were included. Assessment of cord blood haemoglobin, blood group, albumin and bilirubin levels was done. Follow-up for first consecutive five days after birth was done and assessed daily to look for evidence of jaundice, sepsis or any other illness. Serum bilirubin was evaluated at 72-96 hours of life in all neonates and was done early, if clinically indicated. Receiver’s Operating Characteristics curves were used for calculating the cut-off values of cord blood albumin and bilirubin in relation to hyperbilirubinemia.
Result: The cut-off values obtained for albumin and bilirubin of cord blood was < 2.56 mg/dL and >2.33 mg/dL respectively at optimum sensitivity and specificity. Cord blood bilirubin was found to be highly sensitive for early recognition of significant neonatal hyperbilirubinemia as compared to cord blood albumin and can be used for screening purpose.
Conclusion: Cord blood albumin and bilirubin can be used for negating the development of NNHB, but for screening purpose, cord blood bilirubin is more predictive of neonatal hyperbilirubinemia.

Published: November 2021

Introduction: Diabetic Ketoacidosis (DKA) presents with spectrum of clinical manifestations and awareness regarding this amongst physicians is crucial. The study aimed to chronicle the clinical profile of DKA in type 1 diabetes mellitus (T1DM) children.
Methods: The study was conducted at a tertiary care hospital including patients with signs and symptoms of DKA with either debut or established T1DM (n = 38). Detailed clinical history, examination and laboratory investigations were carried out. Differences in frequency distribution concerning demographics and clinical data were analysed in R-studio software (v.1.2.5001).
Results: Kussmaul breathing (49.97%) was the commonest presentation. Infection (39.46%) and poor compliance due to inadvertent omission of insulin therapy (50%) were the commonest precipitating factors. Mild, moderate and severe dehydration was present in 44.74%, 39.47% and 15.79% respectively. Forty-five percent patients had moderate while 34.21% and 21.05% had mild and severe DKA respectively. Seventy-five percent and 52% patients were below 3rd percentile for height and weight respectively. High number of patients had past history of viral infections, were diagnosed in winter, belonged to 2nd or 3rd birth order and from lower middle class. Patients with poor compliance to insulin belonged to lower middle (40%), upper lower (53.33%) and lower class (6.67%).
Conclusions: DKA can be diagnosed early by identifying dehydration, Kussmaul breathing, polyuria and altered sensorium. Infection and poor compliance due to omission of insulin therapy were the commonest and preventable precipitating factor for DKA. Poor compliance to insulin can be attributed to lower socioeconomic class. Awareness among physicians concerning clinical profile of DKA is crucial.

Published: November 2021

Introduction: Due to complex dosage calculations, requirement and different pharmacokinetics profile of drugs in paediatric population, there is a risk of development of drug resistance due to the excessive and inappropriate use of antibiotics. The aim of this study is to determine the antibiotic prescriptions pattern and analyse the rationale use of antibiotic in paediatric patient.
Methods: A prospective observational study was carried out for the period of six months. Data was obtained from the records of paediatric patients between six months to 12 years of age who visited the hospital for febrile illnesses. Appropriateness of the prescriptions was evaluated by considering various parameters like selection of antibiotics (adherence to standard treatment protocols of childhood febrile illnesses), dose, dosage form, route, frequency and duration of antibiotic administration. Quantitative data was analysed in terms of percentage and graphs.
Results: One hundred and fifty prescriptions in a successive manner from paediatric department were collected and analysed, out of which 40% were male & 60% were female cases. The mean age of the patients was 5.9 ± 3.3 years. The range of duration of antimicrobial therapy was 3 - 9 days (6.03 ± 3.53 days). Sixty six percent of paediatric patients were on single antibiotic and most of the paediatric patients were receiving parenteral preparation. The antibiotic treatment was given on the basis of definitive diagnosis in 52% and empirical therapy in 46% cases. Antibiotic prescribed were from class cephalosporin (80%) followed by penicillin (18%) and microcline (14%), glycopeptides (2%) and nitroimidazoles (2%).
Conclusions: Febrile children received antibiotics on an empirical basis, in accordance with standard treatment protocols. Cephalosporins are the major class of drugs prescribed.
Varied presentations of Wilson’s Disease in Childhood - A Case Series and Review of Literature
Authors: Chaudhary Richa , Lohiya Sham , Vagha Keta , Damke Sachin
Published: November 2021

Wilson’s disease is an autosomal recessive disorder of copper metabolism associated with deposition of copper in various organs including the heart and the brain. Hepatic manifestations are the commonest but various extrahepatic manifestations are known which include neuropsychiatric features, haemolytic anaemia, arthropathy etc. Knowledge of all these manifestations result in early clinical suspicion and the diagnosis of Wilson’s disease is confirmed by increased urinary copper levels and decreased serum cerruloplasmin level. Other tests which can be done to confirm the diagnosis include molecular testing and liver copper estimation. Once diagnosed, Wilson’s disease should be treated with chelating agents (e.g. d-penicillamine) and restriction of dietary copper. Timely treatment with zinc acetate or d-penicillamine prevents progression of the disease in asymptomatic children. Adequate chelation also results in good overall prognosis even in symptomatic children. Here we report a case series of nine children with different manifestations of Wilson’s disease throwing more light on the subject.

Authors: Y Ramesh Bhat , Kashyap Harish , Kini Pushpa , Hebbar Shrikiran
Published: November 2021

Introduction: Children with global developmental delay (GDD) are at greater risk to have hearing impairments. These impairments interfere with developmental progress or rehabilitation effects. Hearing impairments may be correctable and if so, may improve developmental outcomes. We aimed to study the incidence, characteristics and probable risk factors of hearing impairment in children aged six months to two years with GDD.
Methods: In this prospective study, an auditory evaluation was carried out by a trained audiologist in children with GDD. Transient evoked otoacoustic emissions (TEOAE) and brainstem auditory evoked response (BERA) were assessed in these children. Hearing loss was classified based on Goodmann's classification.
Results: Of 113 children with GDD assessed, hearing impairment was identified in 35 (30.9%) children. Of 35 children, 22 (62.8%) had isolated sensorineural hearing loss (SNHL). Conductive hearing loss was identified in four (11.5%) and combined hearing loss in nine (25.7%). Of 31 children with SNHL, hearing loss was bilateral in 25 (80.6%).  In SNHL, hearing loss was profound in one (3.2%), severe in 14 (45%), moderately severe in three (9.6%), and moderate in five (16.2%).  Hearing impairment was associated with 31.7% (20/63) children with cerebral palsy. Kernicterus was another predominant risk factor associated with SNHL. Metabolic disorders, otitis media, tuberous sclerosis, and metachromatic leukodystrophy were other conditions associated with hearing impairment.
Conclusions: Hearing impairment is accompanied by about a third of children with GDD. The hearing impairment in children with GDD tends to severe SNHL type in about 45% and bilateral in about 80%.

O câncer é uma enfermidade que evolui progressivamente todos os dias. Para obter um diagnóstico e, consequentemente, um tratamento desta doença, o médico precisa explorar uma quantidade enorme de dados. Muitas vezes a especificidade deste distúrbio celular é algo raro, o que exige elaborar um plano de tratamento mais agressivo, detalhado e inovador, realizado poucas vezes. Porém, a troca de informações sobre todas as ocorrências da doença sempre foi deficitária, já que o câncer se apresenta de forma multifacetada e em diferentes estágios. Sendo assim, este artigo tem por objetivo demonstrar a colaboração da tecnologia cognitiva no tratamento de tal enfermidade. Por meio da computação cognitiva é possível detectar e tratar um câncer, pois o computador recebe subsídios do prontuário do paciente, compreende tais informações, acessa a base de dados e entrega páginas de literatura médica referente ao caso específico e também de casos semelhantes, as quais servem de embasamento, tanto para a abordagem do tratamento, quanto para acompanhamento comparativo dos resultados de cada fase da doença, podendo elevar as chances de cura.

Published: November 2021

Natural disasters that cause tremendous material harm and threaten human lives, infrastructure, and economic and social activities become more frequent. While most
material and human casualties are the effects of sudden and brief natural disasters, it is not possible to disregard long-term disasters, most frequently triggered by climate change. Damage from long-term disasters is quite significant and hampers the sustainability of the economy and life in densely populated cities. Following climate change, it is concluded that special attention should be paid to coastal cities, cities along rivers and the potential risks of possible disasters should be reduced before they materialize. The reduction of disaster risk is an endeavor involving various professional fields, viewpoints, and stakeholders. An integrated approach that brings together all the necessary elements is therefore required. The planning for protection against natural disasters and in the very moments when it occurs, it is necessary to quickly obtain reliable data to coordinate activities in the field well. However, there are problems in the field with the availability, access, and spatial data use. In this sense, the Spatial Data Infrastructure (SDI) can provide an appropriate framework for sharing spatial data through the cooperation of administration, public, and private institutions and citizens.
Applying Simulation Modelling in Quantifying Optimization Results
Authors: Stanković Ratko , Božić Diana
Published: November 2021

Improvements achieved by applying linear programming models in solving optimization problems in logistics cannot always be expressed by physically measurable values (dimensions), but in non-dimensional values. Therefore, it may be difficult to present the actual benefits of the improvements to the stake holders of the system being optimized. In this article, a possibility of applying simulation modelling in quantifying results of optimizing cross dock terminal gates allocation is outlined. Optimal solution is obtained on the linear programming model by using MS Excel spreadsheet optimizer, while the results are quantified on the simulation model, by using Rockwell Automation simulation software. Input data are collected from a freight forwarding company in Zagreb, specialized in groupage transport (Less Than Truckload - LTL).

The introduction of precision agriculture increased the efficiency of plant production, while simultaneously reducing the production cost. Precision irrigation can be considered as the combination of sensors, computer software and irrigation systems. Precision irrigation has reduced water consumption and increased yields, and thus increased economic profits. The development of new crop monitoring technologies in precision irrigation has been made possible by the imaging and analysis of real-time crop condition data. The aim of this study was to describe the present state and possibilities of precision irrigation in practice in the EU and Croatia. An overview of the current precision irrigation technologies, as well as its adaptive management to the decision-making in agricultural water management, represents a fundamental basis for future practical studies in precision irrigation.
ON THE PHOTOGRAPH COLLECTIONS TAKEN BY AMERICAN MILITARY OF THE POLAR BEAR EXPEDITION ON THE NORTH OF RUSSIA DATED TO THE CIVIL WAR PERIOD 1918–1919
Authors:   Independent researcher, Krasnoyarsk, Vonog E.A.
Published: November 2021

Nowadays visual history and its significance characterized by a broad interdisciplinary approach cannot be overestimated. Since 1991 when the Austrian historian and researcher of images Gerhard Jagschitz (1940–2018) first used the term «visual history», photographs and, perhaps, film documents began to be perceived by the scientific world not only as illustrative material, but also as a storehouse of new, but somewhere forgotten information, for example, concerning the appearance of settlements and people living there, everyday life and imperatives of human behaviour, as well as events in certain historical periods. In this article the author presents the data concerning the American military that gathered collections of photographs from the Polar Bear Expedition of the period 1918–1919. During the First World War, this expedition was undertaken by the United States to the territory of the European part of the North of Russia in order to prevent the German Empire from encroaching on the resources of Russia, taking advantage of its weakness as a result of the political crisis. This military mission, carried out jointly with other allied states, in the history of Russia will be called a foreign military intervention, which, unfortunately, became a catalyst for a bloody civil confrontation. In the course of the study, not only the names of the founders were revealed, but also the modern holders of photo collections located in the United States, providing almost free access to all of them. Particular attention is paid to such an important component of attribution of photographic documents as the identification of the American photographers personalities involved in the creation of the visual image of the Civil War in the North of Russia.

The period of Soviet nationality policy was of the utmost importance for the Evenk National (Autonomous) District in the 1920–1970. This article analyzes in detail the place and role of the Evenk National District in the light of Soviet nationality policy. Critical analysis of scientific literature, quantitative and qualitative content analysis of archival material, including the use of the "VAAL" psycholinguistic expert system, were used as research methods. The research sample included the materials of the leading national newspaper of Evenkia — "Soviet Evenkia" for 1960. This material made it possible to reconstruct the history of the development of the Evenk National (Autonomous) District from the moment of its formation in 1930 to 1960 in the context of the Soviet nationality policy, as well as to identify the priority topics and problems that underlie the District's national policy. As a result of the analysis of 78 articles published in 64 issues of the newspaper "Soviet Evenkia" for 1960, the following conclusions were drawn: 1) the most frequently raised topic is the topic of collective farm life, considered in many respects from a material point of view; 2) the second important topic is the topic of the culture of the region, understood primarily as a developed party propaganda system. At the same time, great emphasis is placed on the elimination of illiteracy and the spread of reading among the population. The need for the development of national art is also mentioned, the distribution of cinema among the inhabitants of the district is supported; 3) the topic of education, touched upon in the articles, is the most problematic. It is mainly associated with solving the problem of forming a "national intelligentsia" in the district; 4) the dynamics of the development of the Evenk national district during the period of the Soviet nationality policy of 1920–1970 is obvious. Evenkia, which received an independent status in 1930, was given the opportunity to develop economically and culturally. The district's dynamic development took place within the framework of the general development policy of the Soviet state.
ORGANIZATION OF THE ARTISTIC LIFE OF BAIKAL SIBERIA BY THE SOCIETY FOR THE PROMOTION OF PUBLIC EDUCATION AND POPULAR ENTERTAINMENT (1900–1908)
Authors:   Irkutsk State University, Tkachev V.V.
Published: November 2021

The article reveals the history of the organization of artistic life in Baikal Siberia by the Society for the Dissemination of Public Education and Popular Entertainment in 1900–1908. At the moment, researchers have not studied in detail the activities of a public association in introducing residents to art, they have not analyzed the constituent and accompanying documents of the organization, which are part of the State Archives of the Irkutsk Region. A more detailed analysis and study of a wide range of sources makes it possible to imagine the process of introducing the inhabitants of Baikal Siberia to art in 1900–1908. The article showed that through historical sources it is possible to understand how this process took place. The society for the dissemination of public education and folk entertainment supported the development of artistic life in Baikal Siberia. A detailed study and analysis of materials from the collection of the State Archives of the Irkutsk Region, where records of active participants in public events have been preserved, proved that the organization actively participated in the process of introducing the inhabitants of Baikal Siberia to art in 1900–1908.
Infrastructure development in Africa (East African electricity sector)
Authors: Barinov Andrey K.
Published: November 2021

In the article, the authors analyze the current state and prospects for the development of the energy infrastructure in the countries of East Africa. They provide data from various sources on the facilities under construction in the field of electricity generation. Today, Africa is a dynamically developing continent with powerful potential that will have a tangible impact on world development in the 21st century. The large-scale transformations that are taking place on the continent require an outstripping pace of infrastructure development, which, despite the success achieved, still does not meet its needs. Africa is the least electrified continent in the world, where half of the population does not have access to electricity.
The authors come to the conclusion that a surplus of installed capacity already exists in certain states of East Africa, and in the medium term will reach regional proportions when all power plants under construction are put into operation. To effectively use the excess of electricity, as well as to unlock the potential of both regional and interregional trade, it is necessary to develop transmission and distribution networks. Their underdevelopment is a serious obstacle to expanding the population's access to electricity.
Companies from both traditional and new partner countries are actively involved in electricity projects in East Africa. The participation of companies from Russia at the moment is very limited, despite the existing experience and technological base. The COVID-19 pandemic that swept the world in 2020 will undoubtedly have a negative impact on global financial flows and the implementation of electricity projects (the suspension of several projects has already been announced). However, according to the authors, the negative impact will not be so large-scale due to the long-term nature of the contracts, as well as the socio-economic significance of the projects.
«Et ma tristesse est claire...» (les notes sur l’œuvre du poete tunisien Tahar Bekri)
Authors: Prozhogina Svetlana V.

Intitulées par la strophe pouchkinienne les notes publiées - sont le temoignage des œuvres des Maghrebins vivant en émigration forcée et la sentant comme l’exil occidental surmontant et la déchirure avec la patrie et les difficultées pénibles des partucularitées de l’hospitalité française. Le tunisien Tahar Bekri a supporté la vie assez dure dans son pays natal étant emprisonné pour sa participation dans la manifestation avec les étudiants défensant la liberté dans les années 70. Apres il est parti en France où il a decidé de triouver ses ideaux, mais il rencontré beaucoup d’autres maleurs.
Malgrès tout T.Bekri a obtenu la reconnaissece et dans son activité scientifique consacrée à l’histoire de la littérature arabe et maghrébine et dans son activite sociale lisant la poésie devant ses compatriotes nombreux, traduisant ses vers en langue arabe. Voyageant partout, il a obtenu les succès et en Tunisie où son ouevre on etudie dans son Université natal et ses livres sont publiés en arabe et en français. Marqué par les Prix litteraires significatives en Europe, traduite en plusieures langues y compris le russe, la poésie de T.Bekri est pleine d’energie de vaincre de l’obscurité dans la vie.
Ce n’est pas par hasard que le poète en son debut s’est nommé comme «Laboureur du Soleil» . Mais si par hasard ce soleil commence à s’eteindre sous les pressions des peines de vies des hommes et la réalité terrestre, dans sa poesie apparaisse toujours la tentative des recherches de ses rayons comme les mirages dan le desert. Le «Chant» publié ci-dessous - est la preuve de l’espoire du poète qui tente a dissiper des crépuscules de sa tristesse de la vie bornée des nombreuses frontières d’aujourd’hui, et desire les changements vers le Meilleur que deviient très actuel à notre temps.
DIFFUSION NUCLEATION OF CAVITIES IN GRAIN JUNCTIONS OF SUBMICROCRYSTALLINE MATERIALS

Published: November 2021

The conditions of diffusional cavity nucleation in submicrocrystalline materials processed by the methods of intensive plastic deformation (equal-channel angular pressing, multiaxial forging, high pressure torsion, etc.) are analyzed. To date, the question of the mechanism of nucleation of cavities in such materials remains debatable due to the fact that the processing of materials by the methods of intensive plastic deformation is carried out at high hydrostatic pressures that prevent the appearance of pores. The possibility of diffusive nucleation of nanopores in the region of triple junctions of grains containing negative strain-induced wedge disclinations, generating high tensile stresses in the vicinity of triple junctions, comparable in magnitude to external hydrostatic pressure, is shown. Such junction disclinations inevitably occur at the grain junctions due to the heterogeneity of the plastic deformation through the ensemble of polycrystal grains. It is shown that an important condition for the nucleation of cavities is not only the presence of high internal tensile stresses from junction disclinations, but also an extremely high concentration of nonequilibrium strain-induced vacancies characteristic of submicrocrystalline metals, comparable in values to the vacancy concentration, at temperatures close to solidus. The influence of the strength of junction disclinations, the value of external hydrostatic pressure and the degree of supersaturation of the material by nonequilibriumstrain-induced vacancies on the rate of diffusional nucleation and the volume of critical pore nuclei is analyzed. It is established that in order to effectively suppress the process of pore formation in the grain boundary triple junctions, it is necessary to apply an external hydrostatic pressure that compensates for internal elastic fields from junction disclinations.
INVESTIGATION OF THE INFLUENCE OF JUNCTION DISCLINATIONS ON PLASTIC FLOW STRESS OF POLYCRYSTALS

Published: November 2021

Plastic deformation of polycrystalline solids is accompanied by the appearance of linear rotational-type mesodefects at grain boundary ledges and triple junction of grains, such as starin induced junction disclinations. Junction disclinations generate long-range spatially inhomogeneous fields of elastic stresses, which significantly influence on the structure formation, strain hardening and fracture of materials. In present work a comparative analysis of the contributions of junction disclinations of different sign and strength to the plastic flow stress of a polycrystal is performed. The results of calculationsshow, that when a pile-up of lattice dislocations passes through the elastic field of disclinations, general regularities are observed.Regardless of the sign of disclination, it has a retarding effect on the plastic shear. The equilibrium distributions of the linear density and the density of the Burgers vector of dislocations pile-upretarded by the elastic field of disclination are calculated.It is shown that the largest number of dislocations is concentrated not in the pile-up head, as in classical dislocation pile-upsstoped near impenetrable barriers, but in its central part. The dependences of the critical stress of the passage of the head dislocation of the pile-up through the force barrier of disclination are calculated depending on the strength and sign of disclination, the number of dislocations in the pile-up, and the distance between the disclination and the slip plane of lattice dislocations.It is shown that the change in the sign of disclination significantly influences on the form of the equilibrium distribution of dislocations along the length of the pile-up, but practically does not affect the value of the critical shear stress. It is shown that for a fixed number of dislocations in the pile-up, the critical shear stress increases with the distance between the slip plane and disclination. Thus, when plastic deformation is localized, the greatest strengthening effect from the elastic field of junction disclination is achieved not near the boundary, but far from it.
THE RESEARCH OF STABILITY OF STATIONARY ROTATION A ROTOR SYSTEM WITH A LIQUID, THE AXLE OF WHICH IS LOCATED IN ANISOTROPIC FIXINGS

Published: November 2021

Earlier, one of the authors proposed and developed (together with coworkers) an original method to study the stability of stationary rotation of rotary systems containing a viscous liquid and having a drive that maintains the angular velocity of rotation constant. It was assumed that the rotor has axial symmetry, the anchors of its axis are isotropic. The method is based on two theorems, according to which a change in the degree of instability is associated with the possibility of a perturbed motion of the circular precession type. This motion has a remarkable property: the velocity field and the shape of the liquid surface do not depend on time in a specially selected non-inertial reference frame associated with the line of centers. Finding the conditions for the feasibility of circular precession makes it possible to effectively construct the boundaries of the stability regions of the stationary rotation regime in the space of problem parameters. In addition, the study of the occurrence of circular precession allows us to find the conditions under which a subcritical (supercritical) Andronov-Hopf bifurcation takes place in the rotor system and to identify "dangerous" (“safe”) sections of the boundaries of the stability regions. In this paper, the previously proposed method of stability research applies to systems in which the rotor axis is located in anisotropic Laval type anchors. In the study of rotary systems of this type, it is possible to link the change in the degree of instability with the feasibility of perturbed movements of the elliptical precession type. It can be shown that the imaginary characteristic numbers of the equations in deviations from the stationary rotation mode are possible only in the case when there is a perturbed motion in the form of an elliptical precession. An example of a study of the stability of stationary rotation of a typical rotary system is given. Mechanical effects caused by the fact that gyroscopic stabilization becomes impossible with anisotropic fixing of the rotor axis are noted.
