Рroperties of wear resistance nickel-free steel with secondary curing for building up stamps of metal hot processing
Authors: Bagrov Valeriy , Hlushkova Diana
Published: September 2022

Problem. The problem, i.e. the reduction of energy and resource consumption during surfacing of a stamping tool can be solved by using dispersion-hardening alloys, limitedly alloyed with chromium (up to 3%), increasing the amount of carbide phase due to the introduction of carbide-forming elements, replacing nickel with manganese, and using surfacing with a de-current additive for their application. The purpose of the work is to increase the wear resistance and heat resistance of secondary hardening surfacing steels by improving the composition of alloying powder wires due to the optimization of the content of titanium, molybdenum and chromium. Methodology. Surfacing was performed with a TS-17M welding tractor under a flux of flux-cored wires with a de-energized additive fed into the main part of the welding bath. Surfacing modes – Iд≈300......320 A; Ud≈34...36 V; Un≈23.7 m/h; Up.e.≈93.75 m/h. The participation rate of the de-energized additive varied within 0...75%. Results. The increase in the content of the [TiC] phase contributed to the increase in the heat resistance of Cr-Mn-Ti alloys based on iron. The introduction of [Mo] stabilized the value of hardness at elevated temperatures, increased heat resistance and hardness during dispersion hardening and additional diffusion formation of the carbide phase during aging. Originality. To increase the alloying of the deposited metal, surfacing with de-current additive was proposed, which allowed to increase the assimilation coefficients of alloying elements. Practical significance. Production tests of stamps welded with these steels made it possible to increase their durability by 1.8 times compared to 5KHNM steel.

Authors: Dmitrik Vitaly , Syrenko Tatyana
Published: September 2022

Problem.  It is necessary to study the relationship of the structure of welded joints with the development of porosity to further obtain such structure, which is characterized by increased resistance to vapor formation. Goal. Study of the peculiarities of nulceation of pores in the metal of welded joints from heat-resistant perlite steels operating in creep conditions to reduce the intensity of pore formation. Methodology.  The structure of the metal of welded joints was studied using a macrostructural, microstructural, electron-microscopic, micro-X-spectral and radiographic method. The process of formation of micropores and microcracks was carried out by using electron and light microscopy. Carbide phases were studied by analysis of precipitation using the method of photometry. Results. It was found that creep at welded joints above 270000ch are initially born at the grain limit α – phase – coagulation carbide, and that the pore size of 0.03-0.07 μm, can be considered critical, which is confirmed by an intense increase in their size when working welded joints above 270000. Originality The formation of micropores in heat-resistant pearl steels, during long-term operation in creep conditions, is due to the compatible course of diffusion and deformation processes. Such processes in welded joints are due to their much greater structural heterogeneity.  Practical value.  In the practical plane, the task is to slow down the processes of deformation and diffusion in both steels and welded joints — by obtaining an initial structure with improved qualitative characteristics.
Developing a technological complex for restoring the properties of rolled rolls reduced in the process of grinding
Authors: Volkov Оleh
Published: September 2022

Problem. The problem of increasing the resource of equipment for rolling production is on time. Rolling mills are a piece of equipment for rolling objects made of metals and alloys. They work in difficult operating conditions: at considerable loading, friction and the raised temperatures. As a result, there is a rapid wear of their work surfaces, which leads to defects. Due to the predominantly high cost of rolled rolls, it is better to restore them than to replace with new ones. This is more profitable economically and can be realized by using different methods of influencing the structural condition of the products’ surface. The use of, for example, TFH technology [1,2] or other methods of surface strengthening is possible to solve such problems. Goal. The purpose of the work is to develop a technological complex to restore the properties of rolled rolls, which were reduced in the process of grinding. The subject of the research are the samples in the form of rolled rolls, which are made of 40X steel. To achieve this goal, heat treatment of natural samples was carried out in different modes. Metallographic analysis and measurement of hardness of natural samples after their heat treatment in different modes was made. The optimal mode was selected, which provided the necessary properties. Heat treatment of rolled rolls in need of restoration was carried out according to this mode. Methodology. Two heat treatment modes were used to restore the required hardness of the rolling rolls hardening with heating to 860ºC and cooling in water; hardening with heating to 860ºC and cooling in 10% aqueous NaCl salt solution. Results. The cooling properties of the saline solution are higher than those of water. This ensured greater completeness of the martensitic transformation and the formation of a fine-needle martensitic structure with a small amount of Cr carbides. Therefore, a technological complex for restoring the properties of rolled rolls, which were reduced during grinding, was proposed. It consists of quenching from a temperature of 860°C with cooling in 10% aqueous solution of NaCl salt. After hardening it is necessary to carry out low-temperature release at a temperature of 180ºC for 2 hours with accelerated cooling.
Studying the values of distribution of chromium-nickel steel microhardness using statistical methods
Authors: Dіakonenko Nina , Khatsko Natalia , Khatsko Kirill
Published: September 2022

Problem. Mathematical statistical methods are used to solve material science problems. New phases may be formed that are inherent only in this type of external action in the process of mechanical tests. In the presence of a multiphase structure, the use of the microhardness method provides measurement results that do not always correspond to the phase composition. In this regard, modeling the distribution of microhardness of phase components is of interest, since it allows obtaining indirect data on the processes that occur. The simulation of the experimental data on the microhardness values of chromium-nickel steel in the initial, hardened state and after mechanical friction tests were carried out using mathematical methods of the Microsoft Excel software package.Calculations have shown that both in the initial and quenched states, the set of micro hardness values of the ferrite - martensite matrix is described by a normal distribution curve (A = 0). However, the distribution curve for the hardened sample has a large dispersion (in the initial state 29 in the hardened - 47). This experiment can be explained by the fact that only a part of the grains undergoes martensitic transformation because of hardening, and their microhardness increases. Another part of the grains retains the ferrite structure. The average value increases from 336 kg / mm2 in the initial state to 510 kg / mm2 in the hardened state. Distribution curves of microhardness values of specimens that have passed mechanical friction tests have a completely different form. For them, the distribution curves of microhardness values have some asymmetry. In this case, for ferrite-martensite matrices, the asymmetry is positive (A = 0.59), and for the white zone it is negative (A = -0.59). This indicates that the formation of the white zone is preceded by an increase in the stress state of the matrix to a certain level. The obtained results of modeling the distribution of microhardness can be used to determine the wear resistance of the friction unit, which largely depends on the metal structure formed during the runningin process.

Annotation. Problem. The problem is to obtain a database on the structure and properties of Pb-Sn solders, which are widely used in radio engineering. Target. The purpose of this work was to study the influence of the chemical composition of low-melting solders of the Pb-Sn system on the main mechanical properties and structure. Method. To achieve this goal, a complex of metallographic, mechanical and analytical studies of samples in the initial state was carried out. Results. The hardness of POS-40 and POS-61 solders turned out to be significantly higher compared to the hardness of the pure components from which they are formed. Mechanical studies have shown that the strength characteristics in POS-40 solder are lower, and ductility is higher than in POS-61. Both alloys had approximately the same relaxation properties and within 100 seconds the stress decreased by 70-80%. These data testify to the high ability of the materials that were studied to relieve stresses arising in the junction. Metallographic studies have shown that the structural state of the alloys that have been studied corresponds to the Pb-Sn diagram. The data obtained as a result of research on the properties and structure of POS-40 and POS-61 solders can be used in practice.
THE ESSENCE AND FEATURES OF THE MANIFESTATION OF DEFICIENCY AND IMBALANCE OF THE MEDICAL STAFF IN THE STATE HEALTHCARE SYSTEM (ON THE EXAMPLE OF THE VOLGA FEDERAL DISTRICT)
Authors:   Institute of Social and Economic Researches, MIGUNOVA YU.V.
Published: September 2022

Based on the selected indicators - the provision of the population with medical personnel, their distribution by specialties in accordance with the calculation methodology of the Ministry of Health of the Russian Federation - a study of the problems of shortage and imbalance of medical personnel at all levels of the public health system was carried out. The study involves the study of statistical data based on indicators characterizing the employment of medical personnel with higher education in the period 2010-2019. According to the results of statistical analysis, the provision of doctors in Russia decreased by 2.8% from 50.1 people for 10 000 people population up to 48.7. The same trends can be traced when analyzing the indicator in the Volga Federal District from 1. people for 10 000 people population up to 46.7 in 2019. The study of the provision of doctors by specialty in the Republic of Bashkortostan was carried out in accordance with the methodology developed by the Ministry of Health of the Russian Federation. As a result, a serious shortage of personnel was revealed for such specialists as surgeons, therapists, psychiatrists, pediatricians, etc., as well as a structural imbalance of personnel among phthisiatricians, traumatologists, orthopedists and endocrinologists. To solve the problem of a shortage and imbalance of personnel in the health care system, it is first of all necessary to change the approach not only to the methodology for calculating the need for doctors, but also to understanding the role and place of a doctor in modern society. The issues of regulation and training of medical personnel should not depend solely on market mechanisms, commercial demand for certain specialties. The provision of the population with medical personnel is a national task, therefore there is a need to create a mechanism under which students of those medical specialties will be trained on a budgetary basis, the need for which is dictated by the interests of the population in providing high-quality medical care and the capabilities of the public health system itself as a whole. In order to meet the current and future needs of this area, it is proposed to create employment centers at medical colleges and universities, as well as develop retraining programs for specialists with medical education in order to satisfy staff shortages in the healthcare sector and even out the imbalance in individual specialties.

In the process of extraction of hydrocarbon raw materials, in addition to mechanical disturbance of the soil cover, it is chemically contaminated with hydrocarbons and heavy metals contained in oil and oilfield wastewater, mainly of sodium chloride composition. Combined pollution has a more pronounced adverse effect on plants and soil biocenosis than each pollutant alone and leads to a very rapid loss of soil fertility. The aim of this work was to screen for new strains of hydrocarbon-oxidizing microorganisms resistant to elevated concentrations of sodium chloride and heavy metals. Isolation of strains of microorganisms from samples of technogenically contaminated soils from the territory of the Republic of Bashkortostan was carried out by the method of enrichment cultures on a liquid mineral medium of Raymond with oil. The hydrocarbon-oxidizing activity of the isolates was determined by the degree of destruction of the aliphatic oil fraction by the gas chromatographic method after extraction with hexane. The resistance of strains to the presence of sodium chloride and heavy metals (Zn, Co, Cd, Cu, Pb, Ni) was established by their growth on meat-peptone agar with various concentrations of NaCl or salts of these metals. Of the 14 isolated strains, 6 were selected, most actively growing on a solid medium with oil. The highest abundance and the most significant hydrocarbon-oxidizing activity during cultivation in a liquid medium with oil was found in strain 22 (the degree of oil biodegradation was 93.0%). All microorganisms were halotolerant and grew at 5 and 7% sodium chloride in the medium, but cultures 11 and 41, which withstood a NaCl concentration of 10%, turned out to be the most resistant to salinity. Strains 33.1 and 33.2 had the highest resistance to the action of metals. Lead and zinc were the least toxic to microorganisms. The results obtained should be considered preliminary, and the isolates themselves need further research with a view to their possible application in ecobiotechnology.

Published: September 2022

In the process of increasing destructive anthropogenic pressure on the geobiocenoses of our planet, the protection and preservation of wild ungulates populations through the introduction of new biotechnical technologies is an increasingly significant and urgent environmental task. The development of biotechnical innovations adequate to the current state of nature requires a multi-vector approach and, first of all, a constructive analysis of foreign experience in the biotechnical arrangement of national natural territories. These studies are an effective methodological contribution for implementation in specially protected natural areas (protected areas) Of Russia. A biologically cost-effective example of this symbiotic process is the biotechnical experience of the state nature reserve of federal significance "Kirzinsky" (Novosibirsk region, Barabinsky, Chanovsky districts). Here, in a scientific format, the most productive biotechnical systems in such important countries as England, the USA, Poland, etc. were studied, which demonstrated the progressive dynamics of conservation and increase in the number of wild ungulates. Taking into account the application of some foreign biotechnical techniques, the reserve has developed and implemented its own integrated concept for the conservation of Siberian roe deer (Capreolus pygargus) in winter. This biotechnical innovation has led to a qualitative biological result. The number of Siberian roe deer has increased more than 10 times over the past 12 years: from 156 individuals to 2144.

Authors:   R.G. Kuzeev Institute for Ethnological Studies, GALIEVA F.G.
Published: September 2022

The relevance of the work lies in the demand for materials characterizing the peoples of the Southern Urals and the Urals in the XIX century to reconstruct the history and culture of the region. The purpose of the article is to identify ethnographic materials about the Russian population, which over the past centuries formed the demographic majority and largely determined the ethnic processes in the region. The method of research is a historical and comparative analysis of information about the Russian population of the past centuries with the field materials of the author of the article collected in recent decades. It is revealed that the materials of V.S. Russian Russians of the Zlatoust district of Ufa province, immigrants from Kungursky district of Perm province, that is, representatives of the North Russian ethno-cultural tradition. M.V. Kolesnikov in the late 1880s described the customs and customs of the Russian population of Belebeyevsky and Ufa counties, whose ethnic culture formed by the fusion of traditions of immigrants from different provinces of Russia, especially the Central Russian strip, and interaction with local peoples. Priest K. Yevlantiev in 1878 described the economic activities of the Belebeyevsky district, and the priest M.V. Burdukov in 1905 - the Menzelinsky district of the Ufa province. Their materials allow us to study the process of adaptation of the Russian population to local conditions. Since the 1840s, the newspaper has published information about folk and religious holidays held in villages and cities, where representatives of different ethnic groups, estates, confessions gathered. In the 1860s - 1870s, R.G. Ignatiev presented information about the days of Semik, Trinity, Annunciation, St. George's Day, which were special for the peasants of the Ufa province. Thus, the newspaper's materials provide a variety of information on the ethnic history, economic activity, material and spiritual culture of the Russian population of different counties, their regional features in chronological frames from the 1840s to 1905, ethnocultural processes in the region. Field studies show the preservation of some customs in villages remote from the centers of urbanization.
SOME SOCIAL AND RELIGIOUS IDENTITIES OF UKRAINIAN PROTESTANTS OF THE URAL REGION
Authors:   R.G. Kuzeev Institute for Ethnological Studies, KLYASHEV A.N.
Published: September 2022

This work is devoted to revealing the ranking of the components of social and religious identities according to the degree of importance among Ukrainians - members of Protestant religious organizations operating in the Southern, Middle and Polar Urals. Ukrainians are the largest group of Protestants in the studied regions, having a "foreign" origin. The materials are presented in comparison with data on the general sample of believers. It was found that the systems of identities in the representatives of both control groups are similar; the most important are religious and family identities, the last place in terms of importance is occupied by ethnic identity. At the same time, the results of the research showed that for Ukrainian respondents, religious and family identities are of greater importance, while civil and ethnic identities are of less importance, compared to respondents from the general sample. The greater commitment of Ukrainians to biblical values may be due to the fact that evangelical Christianity historically has more rooted traditions in Ukraine than in Russia; believers who were born and lived for some time on the territory of Ukraine realize evangelical paradigms more fully in their lives.

Authors: Gladden James D. , Gulati Rajiv , Sandoval Yader
Published: September 2022

Safe and efficient arterial access is critical for optimal patient outcomes and procedural success in the cardiac catheterization laboratory. Because of the lower risk for vascular and bleeding complications, as well as patient comfort, transradial access has become the predominant approach for diagnostic coronary angiography and percutaneous coronary intervention. Transfemoral access, however, is still required for selected complex percutaneous coronary interventions, mechanical circulatory support, and structural heart procedures. The use of adjunctive technology and techniques such as ultrasound guidance and micropuncture can be combined with fluoroscopy and palpation to improve outcomes associated with vascular access. The importance of optimal access techniques has augmented due to increasing volume of structural heart and mechanical circulatory support procedures requiring large bore sheaths. In this document we review the contemporary techniques for femoral and radial access in the cardiac catheterization laboratory.

Published: September 2022

Background: The classic electrocardiogram (ECG) criteria have been applied to left ventricular hypertrophy (LVH) screening but have low sensitivity. Recently, the newly proposed Peguero-Lo Presti criterion has been proven to be more sensitive in detecting LVH in patients with hypertension than several current ECG criteria. The diagnostic value of the Peguero-Lo Presti criterion in hypertrophic cardiomyopathy (HCM) patients has not been fully evaluated. This study aims to test whether the new Peguero-Lo Presti criterion can improve the diagnostic performance in patients with HCM. Methods: This study included HCM patients and sex-and age-matched healthy control subjects. The diagnostic performance of the Peguero-Lo Presti criterion was evaluated along with the Sokolow-Lyon criterion, Cornell criterion, and total 12-lead voltage criterion. Results: Overall, 63 HCM patients and 63 controls were enrolled. The diagnostic accuracy, sensitivity and specificity of Peguero-Lo Presti criterion were 74.6%, 73.0% and 76.2%, respectively. The Peguero-Lo Presti criterion had the highest sensitivity, while the Cornell criterion and Sokolow-Lyon criterion had the highest specificity (96.8%). The area under the curve (AUC) showed that the Peguero-Lo Presti criterion was 0.809 (95% CI, 0.730–0.874; p < 0.0001), Sokolow-Lyon criterion was 0.841 (95% CI, 0.766–0.900) and total 12-lead voltage criterion was 0.814 (95% CI, 0.735–0.878). There was no significant difference in AUC between Peguero-Lo Presti criterion and Sokolow-Lyon criterion (p = 0.533), or Peguero-Lo Presti criterion and total 12-lead voltage criterion (p = 0.908). Receiver operator characteristic curve analysis of the Peguero-Lo Presti criterion showed an optimal cutoff of >3.15 mV for men (sensitivity: 63.9%; specificity: 80.0%) and >2.29 mV for women (sensitivity: 78.6%; specificity: 85.7%). Conclusions: The Peguero-Lo Presti criterion provides high sensitivity for ECG diagnosis of HCM patients and can be considered when applicable but this needs to be verified in a larger population.
Warfarin-Induced Calcification: Potential Prevention and Treatment Strategies
Authors: Wang Xiaowu , Peng Langang , Ma Jipeng , Zhang Liyun , Liu Jincheng
Published: September 2022

Warfarin is clinically used as the first choice for long-term anticoagulant therapy, and for the prevention of thromboembolic events. However, when used at low doses in the long term or high doses in the short term, warfarin treatment may result in tissue calcifications—such as calcifications in the coronary arteries, peripheral vascular system, blood vessels of patients with atrial fibrillation and chronic kidney disease, and vascular valves—and atherosclerotic plaque calcification. These warfarin-induced calcifications may affect cardiovascular function and exacerbate diseases such as diabetes and hypertension. Studies have shown that quercetin, osteoprotegerin, sclerosin, and sodium thiosulfate may alleviate these effects by interfering in the Wnt/β-catenin, TG2/β-catenin, Bone Morphogenetic Protein 2 (BMP2), and Eicosapentaenoic Acid/Matrix Metallopeptidase-9 (EPA/MMP-9) pathways, respectively. Nevertheless, the mechanism underlying warfarin-induced calcification remains unknown. Therefore, the question as to how to effectively attenuate the calcification induced by warfarin and ensure its anticoagulant effect remains an urgent clinical problem that needs to be resolved. To utilize warfarin rationally and to effectively attenuate the calcifications, we focused on the clinical phenomena, molecular mechanisms, and potential strategies to prevent calcification. Highlighting these aspects could provide new insights into the effective utilization of warfarin and the reduction of its associated calcification effects.

Published: September 2022

The use of systematic reviews to collate and summarise evidence is considered one of the great intellectual achievements of recent times. Evidence synthesis has had far-reaching impacts and has helped to inform decision-making in multiple fields. However, it also faces three problems: (i) reviews cannot be relevant to everyone, hampering decision-making, (ii) multiple conflicting review are often produced, and (iii) reviews can become out-of-date rapidly. Here we present a solution to these problems that we term 'dynamic meta-analysis.' With a tool we have developed, users can filter and weight evidence depending on their interests to produce analyses that are highly relevant to their needs.

Seeing One Another: The Creation of The Sawubona Healing Circles
Authors: Auguste Evan , Lodge Tania , Carrenard Niara , Onwong'a Jana Robina , Zollicoffer Ashley , Collins Dana , London Laneay
Published: September 2022

In 2020, The Association of Black Psychologists (ABPsi) drew attention to how the history of racism in the U.S. had created and exacerbated extant medical racial inequities to the detriment of Black people. In recognition that solutions based solely in Western frameworks cannot fully address the mental health needs of Black people, ABPsi began devoting collaborative efforts to develop culturally-grounded healing responses for the unique experiences of race-based invisibility and trauma. Amid the pandemic, people of African-descent also experienced a number of other mass racial traumas, including a wave of widely publicized police violence. Beginning with COVID-19, these intersecting pandemics of racism elucidated the need for healing, particularly culturally-grounding healing. In consultation with the Black Family Summit, ABPsi developed a pilot investigation, the Sawubona Healing Circle (SHC) initiative, which are culturally-grounding healing circles to support Black first-responders. Using an African-centered worldview, the circles recognize and validate the specific constellation of anti- Black traumas and stressors, and equip them with African-centered healing methods. This paper outlines the theory, development, implementation, and initial evaluation of the SHC intervention.

Published: September 2022

Substantial race-based disparities exist in federal criminal sentencing. We analyze 380,000 recent (2006-2019) sentences in the JUSTFAIR database and show that these disparities are large and vary considerably across judges. Judges assign white defendants sentences 13% shorter than Black defendants’ and 19% shorter than Hispanic defendants’, on average, conditional on case characteristics and district. Judges one standard deviation above average in their estimated Black-white disparity give Black defendants sentences 39% conditionally longer than white defendants’, vis-à-vis an average disparity of 13%. Judges one standard deviation above average in their estimated Hispanic-white disparity give Hispanic defendants sentences 49% conditionally longer than white defendants’, compared to the average disparity of 19%.

Published: September 2022

Background: Anesthesia as a distinct specialty has evolved much beyond the boundaries of operation theater but the services are yet under-recognized. This may be partly because of the lack of knowledge about anesthesia and anesthesiologist in general public and also due to lack of effort to raise awareness among the general public. This study was done to assess the knowledge and perception about anesthesia and anesthesiologist in patients undergoing surgery in Nepal.
Material and Methods: A total of 719 patients scheduled for elective or emergency surgery in eight hospitals of Nepal were consecutively recruited and interviewed using questionnaire at pre-operative period before evaluation by anesthesiologist or anesthesiology resident. Individual response to each question was graded using three point scale.
Results: The age of the patients ranged from 16 to 87 with a mean of 39.5±15.7 years. Only 31.6% and 28.2% had previous surgery and anesthetic exposure respectively. The majority (69.4% and 49.8% respectively) had good knowledge about health care workers present in operation theater and the ones delivering anesthesia. However, knowledge about anesthesia types and anesthetic agents was poor in 48.4% and 51.9% respectively. The knowledge was poor about person responsible for monitoring and maintaining homeostasis (49%), person responsible for resuscitation (46.5%) and management of anesthesia related complications (49.5%). Remarkably, 48.3% of the respondents had average knowledge about who manages post-operative pain. The mean knowledge score for individual patient was calculated and, 11.1%, 83.4% and 5.4% had poor, average and good knowledge respectively.
Conclusion: Majority of patients undergoing surgery had average knowledge and perception about anesthesia and anesthesiologist.

Published: September 2022

Background: Gallbladder adenocarcinoma is the most common malignant tumor of the biliary tract. Most of gall bladder cancers are detected incidentally only after pathological examination of the excised surgical specimens. In this study we investigated the characteristics of incidental gallbladder cancers in our center. 
Material & methods: We retrospectively reviewed all of the cholecystectomy specimens in sent for histopathology following laparoscopic cholecystectomy in the study period from January 2015 to October 2019. Clinicopathological characteristics were extracted from the patients' clinical charts, which included symptoms, radiological findings, laboratory data, and surgical procedures as well as outcome.
Results: We identified 6 cases of incidental gall bladder cancer, consisting of 4 women and 2 men ranging in age from 28 to 77 years (mean age 60.5 after pathological study of 1530 resected gall bladders. Out of the 6 cases, 1 case was carcinoma in situ of gall bladder, 1 was T1b  and other 4 cases were T2 carcinoma.
Conclusions: The rate of incidental gallbladder carcinoma in our study was 0.39%. This lower incidence could in part be due to increasing use of routine laparoscopic cholecystectomy for symptomatic gallbladder. This strategy of increased early intervention further adds to the advantage of higher chances of gallbladder cancer detection in early stages, and thus better prognosis.

Published: September 2022

The idea of nationalism is a modern idea which has its roots in modern European Renaissance. However, in a country like India, it emerged and developed during the anti-colonial struggle which marks a new beginning of social and political awakening. Generally, we identify Indian nationalism with the ideas of great freedom fighters like Gandhi, Nehru, Subhash, Patel and lokmanya tilak. These great leaders emphasized upon a particular brand of Indian nationalism that looks at Indian civilization as the greatest Civilization on earth. It ignores the operation and suppression of Dalits and other down roden sections of Indian society which has been going on in India for centuries. The dominant Indian nationalism is the based upon the ideas of Brahmanism, manuvad and Aryan racial superiority. It bypasses the nationalist perspectives of Dravidians, communist and the subalterns. It was doctor BR Ambedkar who gave a new definition of Indian nationalism. His nationalism stands for the salvation of Dalits and backward sections of Indian society. The present paper will analyse Ambedkar’s ideas on Indian nationalism and will differentiate it from other brands of nationalism prevailing in India for the last two centuries.

 

Abstract in Hindi Language:

राष्ट्रवाद का विचार एक आधुनिक विचार है जिसकी जड़ें आधुनिक यूरोपीय पुनर्जागरण में हैं। हालाँकि, भारत जैसे देश में, यह उपनिवेश विरोधी संघर्ष के दौरान उभरा और विकसित हुआ जो सामाजिक और राजनीतिक जागरण की एक नई शुरुआत का प्रतीक है। आम तौर पर, हम भारतीय राष्ट्रवाद की पहचान गांधी, नेहरू, सुभाष, पटेल और लोकमान्य तिलक जैसे महान स्वतंत्रता सेनानियों के विचारों से करते हैं। इन महान नेताओं ने भारतीय राष्ट्रवाद के एक विशेष प्रकार पर जोर दिया जो भारतीय सभ्यता को पृथ्वी पर सबसे बड़ी सभ्यता के रूप में देखता है। यह दलितों और भारतीय समाज के अन्य दबे कुचले वर्गों के संचालन और दमन की उपेक्षा करता है जो सदियों से भारत में चल रहा है। प्रमुख भारतीय राष्ट्रवाद ब्राह्मणवाद, मनुवाद और आर्य नस्लीय श्रेष्ठता के विचारों पर आधारित है। यह द्रविड़ों, कम्युनिस्टों और निम्नवर्गों के राष्ट्रवादी दृष्टिकोणों को पारित करता है। डॉक्टर बीआर अंबेडकर ही थे जिन्होंने भारतीय राष्ट्रवाद की नई परिभाषा दी। उनका राष्ट्रवाद भारतीय समाज के दलितों और पिछड़े वर्गों के उद्धार के लिए खड़ा है। वर्तमान पेपर भारतीय राष्ट्रवाद पर अम्बेडकर के विचारों का विश्लेषण करेगा और इसे पिछली दो शताब्दियों से भारत में प्रचलित राष्ट्रवाद के अन्य प्रकारों से अलग करेगा।

Application of Human Capital Theory to Understand Funding Inequities in Dual Language Programs
Authors: Doane Jenna
Published: September 2022

Language is a form of human capital. Human capital refers to skills an individual needs to succeed within the labor market. Originating from The Bilingual Education Act of 1968 (Title VII of the Elementary and Secondary Education Act of 1968), one of many purposes of dual language programs (DLPs) was to provide equal access to classroom opportunities for all students, regardless of their native language. The goal of bilingual programs is to promote the literacy of the English language and their home language. Two-way DLPs in schools were created to help strengthen the English literacy of non-native-English-speaking students, while simultaneously supporting their performance in school. English-speaking students are also within the classroom, while instruction is split between English and the home language of the non-native English speakers. Despite the original focus of equity in these programs, there seems to have been a growing interest in DLPs from native English speakers whose goals are most closely related to human capital and globalization views. In addition, disparities in funding highlight the lack of value placed on DLPs when it comes to equity for non-native English speakers, which are ultimately rooted in the history of oppressive bilingual education policies. The globalization view, coupled with funding inequities, could lead to resource hoarding among certain groups, ultimately negatively affecting English learners’ labor market outcomes later in life due to an inability to access DLPs and utilize the benefits that come from them.

A pesquisa utilizou uma rotina de confecção de rede de drenagem por meio de Sistemas de Informações Geográficas para detecção e dimensionamento de erosões lineares em área de pastagem degradada, a partir de imagens derivadas de um drone. Numa área de pastagem de 77 hectares, situada em Rondonópolis, Mato Grosso, no bioma Cerrado, a partir de missões com RPA foi possível a captura de 478 imagens aéreas com alta resolução espacial (2cm por pixel), que foram processadas para a geração de um ortomosaico de fotografias aéreas, e confecção do Modelo Digital de Elevação - MDE. Na sequência, por meio do MDE houve a extração da rede de drenagem, incluindo a formação de ravinas no terreno, que, quando confrontado com a inspeção do mosaico, permitiu a identificação de processos erosivos lineares. Foram identificados 7 processos erosivos, que possuíam área média de 1.473 m2. O uso das ferramentas de hidrologia no processamento do MDE evidenciou os processos erosivos da área, classificando-os como rede de drenagem e a sobreposição das curvas de nível permitiu observar a direção de evolução desses impactos. A junção dessas análises favoreceu uma análise individual de cada processo erosivo, facilitando assim o planejamento particularizado de medidas e intervenção individualizada.

Identification of erosion processes through hydrological models and high resolution aerial images
 
ABSTRACT: The research used a routine of making a drainage network through Geographic Information Systems for detection and dimensioning of linear erosions in a degraded pasture area, from images derived from a drone. In a pasture area of ​​77 hectares, located in Rondonópolis, Mato Grosso, in the Cerrado biome, from RPA missions it was possible to capture 478 aerial images with high spatial resolution (2cm per pixel), which were processed to generate an orthomosaic of aerial photographs, and creation of the Digital Elevation Model - MDE. Subsequently, through the MDE, the drainage network was extracted, including the formation of ravines on the ground, which, when confronted with the inspection of the mosaic, allowed the identification of linear erosive processes. Seven erosive processes were identified, which had an average area of ​​1,473 m2. The use of hydrology tools in the MDE processing evidenced the erosive processes in the area, classifying them as a drainage network and the superposition of the contour lines made it possible to observe the direction of evolution of these impacts. The combination of these analyzes favored an individual analysis of each erosive process, thus facilitating the individualized planning of measures and individualized intervention.
