Детектирование терагерцевых электромагнитных волн с помощью проводящих антиферромагнетиков
Authors: Сафин А.Р. , Козлова Е.Е. , Калябин Д.В. , Никитов С.А.
Published: June 2021

We investigate a mathematical model of a terahertz electromagnetic wave detector based on a conducting antiferromagnet and a heavy metal. The mechanism of resonant straightening of oscillations is based on the inverse spin Hall effect in a heavy metal under spin pumping from an antiferromagnet. It is shown that the frequency dependence of the constant voltage of the detector has a resonant character with a peak corresponding to the frequency of antiferromagnetic resonance. The sensitivity to an alternating terahertz signal of the proposed detector structure is comparable to the sensitivity of modern detectors based on Schottky and Gunn diodes.

The current dependences of the output optical power and emission spectral characteristics, including their distribution (mapping) over the emitting surface, of vertical AlInGaN LEDs in a wide range of operating currents up to ~ 70A have been studied. Analysis of the current dependence of the LED optical power and emission spectrum reveals that, starting from a certain level of excitation, it is incorrect to use the value of the average current density when interpreting the ìefficiency dropî. The effect of ìcurrent crowdingî around the contacts becomes the main factor in reducing internal quantum and light extraction efficiency, limiting the energy capabilities of the LED.

The temperature dependences of the absorption coefficient of Al2O3, ZnO, TiO2 powders at a frequency of 527 GHz are investigated. A gyrotron with an output power of up to 240 W in CW mode was used as a radiation source for heating the samples. The power absorbed in the samples was measured in the temperature range from 300 to 1000 ° C (for some samples). Compared with experiments at a frequency of 263 GHz, a significant increase (by a factor of 4 - 6) in the absorption coefficient is observed. The results may be of interest to researchers involved in microwave heating of materials.

Consumer Wearables and the Integration of New Objective Measures in Oncology: Patient and Provider Perspectives
Authors: Fonseka Lakshan N , Woo Benjamin KP
Published: June 2021

With one in five adults in the United States owning a smartwatch or fitness tracker, these devices are poised to impact all aspects of medicine by offering a more objective approach to replace self-reported data. Oncology has proved to be a prototypical example, and wearables offer immediate benefits to patients and oncologists with the ability to track symptoms and health metrics in real time. We aimed to review the recent literature on consumer-grade wearables and its current applications in cancer from the perspective of both the patient and the provider. The relevant studies suggested that these devices offer benefits, such as improved medication adherence and accuracy of symptom tracking over self-reported data, as well as insights that increase patient empowerment. Physical activity is consistently correlated with stronger patient outcomes, and a patient’s real-time metrics were found to be capable of tracking medication side effects and toxicity. Studies have made associations between wearable data and telomere shortening, cardiovascular disease, alcohol consumption, sleep apnea, and other conditions. The objective data obtained by the wearable presents a more complete picture of an individual’s health than the snapshot of a 15-minute office visit and a single set of vital signs. Real-time metrics can be translated into a digital phenotype that identifies risk factors specific to each patient, and shared risk factors across one’s social network may uncover common environmental exposures detrimental to one’s health. Wearable data and its upcoming integration with social media will be the foundation for the next generation of personalized medicine.

Teachers’ Misbehaviours in Class and Students’ Reactions: A Case Study
Authors: Alkurdi Reem , Alghazo Sharif
Published: June 2021

This study aims to investigate English as a Foreign Language (EFL) teachers’ misbehaviours in class and their students’ reactions to these misbehaviours. Towards this end, 60 classroom observations of six English language teachers (N=10 each) were conducted at a public school in Jordan. Moreover, a survey was used to elicit 201 students’ reactions to their teachers’ misbehaviours by gauging their satisfaction with the teachers’ communication styles. Finally, the teacher participants were interviewed in order to more deeply understand why such misbehaviours occurred. Analysis of the data is grounded in the Expectancy Violation Theory. The results revealed that when the mean value of teachers’ communication style was more than 3 on a 5-point Likert Scale, the students often perceived their teachers as being positive, and the students compensated most of their teachers’ misbehaviours. However, when the mean value was below 3, the teachers were perceived as being negative, and the students reciprocated for most of the misbehaviours. The results also showed that the students are more tolerant towards their teachers’ misbehaviours as long as the teacher is perceived to be positive. The study provides insights into understanding the student-teacher relationship in EFL classes.

Introduction. Myoid angioendothelioma of the spleen is an extremely rare form of a benign splenic tumor. There is no characteristic symptomatology for this disease. Case outline. We present four patients operated on for myoid angioendothelioma of the spleen. Three patients were without problems while one had nonspecific problems. Two patients underwent laparoscopic surgery and two underwent open splenectomy. In all patients, the definitive diagnosis was confirmed by histopathological examination. By reviewing the aforementioned medical databases of published papers in English, we found a total of eight cases of myoid angioendothelioma of the spleen. In addition to the mentioned number, we have added our series of cases. Conclusion. Twenty-one years after the discovery of myoid angioendothelioma of the spleen, the small number of cases presented in the literature is still a limiting factor in making conclusions and in learning lessons about this disease
Miért van szükségünk közösségalapú egészségfejlesztésre?
Authors: Benyó Béla
Published: June 2021

Összefoglaló: Az Ottawai Nyilatkozat lendületet és teret adott a közösségalapú egészségfejlesztési elméletek és gyakorlati politikák megfogalmazásának. Azóta számos elmélet és bizonyítottan hatásos beavatkozási módszer látott napvilágot e témakörben. Ezek közül néhány kiállta a gyakorlat próbáját és a jó gyakorlatok sorába került. A kutatók kimerítő vitát folytattak a közösségi bevonódás szintjeiről, módjairól, jellemzőiről, azok egymáshoz való kapcsolódásukról. Tisztázták a közösségi részvétel, felhatalmazottság mibenlétét és folyamatjellegét, amely végül munkadefinícióként a WHO Európai Regionális Irodája által is elfogadást nyert. A közösségi felhatalmazottság fogalmának tisztázása gyakorlati jelentőséggel bír, mert meghatározza a közösség szerepét az egészségfejlesztés során, melynek jelentőségét nehéz túlbecsülni. Ennek eredményeképpen válhat valósággá az az elv, hogy a közösség egészségét alapvetően meghatározza azt a tény, hogy milyen mértékben képes a közösség kontrollálni az egészségkockázati tényezők alakulását. A változás igénye elérte hazánkat is, a népegészségügy intézményrendszerének reformja a figyelem középpontjába helyezi a közösség szerepének értelmezését. Éppen ezért aktuálissá vált a téma elméleti áttekintése, összefoglalása. A cikk erre tesz kísérletet.

Training specialists in international relations: rethinking the new paradigm
Authors: Voevoda E. V.
Published: June 2021

The article considers new tasks of universities and faculties training students of international relations. The author analyzes the essence of the concept "paradigm" in education because paradigm serves as the basis of the educational process in universities. The content of professional education depends on the aims of professional education of specialists in international relations. The process of globalization, global changes, challenges and threats bring about the necessity to study specific features of international cooperation in ecology, psychology of conflict, psychology of leadership, etc. In the age of globalization, national economies are converging while national cultures are diverging. Representatives of different nations realize the importance of preserving cultural identity. It is of vital importance to instil tolerance in future specialists in international relations and prepare them for cross-cultural communication. At the same time, it is necessary that they should not only enjoy individual freedom and national cultural identity, but realize their own responsibility to the state. In the modern world, the axiological and educational functions of professional training are growing. At the same time, it is crucial to let the students build a number of professionally relevant competences that will make it possible for them to effectively perform their professional functions. It is the competence-based approach that makes the basis of Federal state education standards, including education standards for faculties of international relations. Another direction that needs developing is training and retraining lecturers for universities specializing in international relations. Foreign language training of lecturers in basic subjects will make it possible for the, to give lectures in foreign languages, particularly in English, which, in its turn, will help to make Russia's universities more competitive.

The Role of the Russian Soft Power in Eurasian Integration
Authors: Lebedeva M. M. , Kharkevich M. V.
Published: June 2021

Soft power is analyzed in the article as a resource of integration in the post-soviet area. The author shows that soft power today is an indispensable resource of any integration policy. The amount of soft power defines the depth of integration. Integration in Eurasia is a natural process and eventually it will be of interest for all the states in the region. Soft power will reduce the transaction costs of integration and increase the attractiveness of the project for other states over the long run. A resource of the Russian soft power which will foster the integration processes in the post-soviet region might and ought to be higher education and science. The development of national science may be not only an integration tool, but also a nation idea and a goal for modernization. The author argues that science and higher education will indeed help Russia deepen the Eurasian integration, overcome the lack of trust among its regional neighbors and channel the positive experience of economic integration in adjacent spheres of interstate relations in the post-soviet area.
Application of Securitization of Leasing Assets
Authors: Linev I. V.
Published: June 2021

Securitization of leasing assets was widely adopted abroad within the last decades. Securitization of leasing assets usually is meant as process of formation of a portfolio based on future leasing payments of one and (or) more leasing company and sale of securities to investors for the subsequent refinancing of leasing operations. These securities can be bonds, actions or bills. Thus the asset leased, acts as providing these papers. Nomenclature of property includes office, medical (first of all, stomatology), training, video the equipment, and also a car, motor-equipment, towers of cellular communication production of heavy mechanical engineering and computers. The essence of securitization of leasing assets consists in isolation of streams of leasing payments from risk of bankruptcy of the leasing company. As the considered mechanism has the greatest development in the USA, so far as consideration of experience of its application in this country is represented especially actual. The special attention is deserved by a question of decrease in credit risk of the investor. External and internal providing is applied to its decision in different types. Interest of participants in securitization of leasing assets consists in distribution of risks between them, emergence of a new source of financing, depreciation of attracted resources, increase of liquidity of a leasing portfolio and optimization by management by balance of the enterprise. Appeal of this tool to the leasing company in a case when it has no available own funds for business development, represents separate interest. Securitization allows the leasing company to expand sources of attraction of the capital and to receive a reserve for the future, and also to broaden the sphere of options of activity and to give it new opportunities for financing of projects. Widespread introduction of schemes of securitization in practice of the Russian leasing business, requires development, and on some aspects -creation of the corresponding legislative base. In the conditions of a tendency observed around the world to broad use of this tool, which gives a powerful impulse to development both bank, and real to sectors, Russia cannot stand aside from this process.
KING'S ENGLISH AND THE ARISTOCRATIC CODE OF COMMUNICATION IN MODERN BRITAIN
Authors: Ivushkina T. A.
Published: June 2021

All inaccuracies and distortions of the language use in modern British media, revealed by Simon Heffer in his book «Strictly English», enable the author of the article to draw a distinct demarcation line between King's English, the English of the press, on the one hand, and the English of the upper classes of Great Britain, on the other. The errors in the press, such as confusion of words similar in a sound form or spelling, the use of foreign words in the wrong meanings, distortions of names, etc. testify to the deterioration of education at some universities of Great Britain. They also point to the lack of a classical education based on the study of foreign languages, Greek and Latin, in the first place, which facilitates learning foreign words and mastering complicated grammar structures and subtleties of modality in the English language. The language of the press is clearly opposed to the language of the upper classes by methods of communication. If the former is characterized by direct and straightforward ways of communication, the latter manifests indirect and hidden ways of interaction. Cultivated by the upper classes and the aristocracy, this code is based on the categories of words which originate ambiguity in speech or texts and raise the eternal question «What is meant by this or that? ». In journalism these categories of words are labeled as «killers» of meaning. They include foreign words which considerably obscure understanding, abstract nouns that serve to create distance and insincerity in communication, adjectives which very often veil the real state of things, serve as a means of linguistic manipulation, especially when used to describe emotions, opinions and feelings. Here, also, belong euphemism and metaphorical meanings of nouns and verbs. The author concludes that, despite stringent prohibition for journalists to use these categories of words in the media, journalists and professional writers would only benefit if they were aware of them as well as of social connotations of words marked as U - non-U words in the book «Noblesse Oblige» by Alan Ross, Evelyn Waugh and Nancy Mitford. Heffer's book allows to clearly see the demarcation line between the English of the media and the English of the upper classes of Great Britain based on play upon words and various implications to express individuality and sense of humour, intellect and social exclusiveness.
FUNCTIONS OF HIGHER PROFESSIONAL FOREIGN LANGUAGE EDUCATION
Authors: Bogatyreova M. A.
Published: June 2021

The article is about the functions of professional higher education dealing with the sphere of foreign languages (FL). There are all indications that these functions are mainly determined by the higher education objectives, the dominating role that foreign languages play in modern society and politics. The analysis of existing linguistic concepts (up to the ХХ-th century) as well as the current state of FL educational system, testifies to the fact that a number of urgent and indispensable changes are needed. The desirable transformations are aimed to amplify the contents of the functional burden of professional FL education. According to the provisions of the latest state standards, the transmission to new paradigms of thinking is primarily provided by the innovation modus, that is intended to steadily develop sociocultural technologies, improve the contents of FL education, increase the effectiveness of students' achievements, work out a new system of monitoring, controlling and assessing academic results. However, multi-media techniques and strategies should be associated with the anthropological paradigm, capable of driving in motion the "front-running" mechanism of sociocultural reproduction. That means that graduates' FL proficiency, alongside with influence, property and benefit, is becoming the most important indicator of social status in modern society. Consequently, multifunctional FL education is supposed to reflect the formation of axiological values of students, their inner motives and personal attitudes that, being embodied in the creative products of speech, exercise an essential impact on valuable society orientations. Evidently, society is intellectual to an extent it applies knowledge which was accumulated in the cultural gene pool of humanity. It is just through the educational channel that the basic value of culture performs the function of adjusting objective reality to individuals' goals and their meaningful implications. The language conjures a subjective image of the objective world, and in the context of individual approach it does not only mean building one's own trajectory of covering the academic material, but also developing strategies of transforming the world. According to the culture-centred principle, which underlies educational functions, the latter tend to unfold logically in any separate classification of functions.
Patriotic Enthusiasm at the Beginning of the First World War
Authors: Yudin N. V.
Published: June 2021

In the present paper from the constructionist perspective is examined one of the most controversial issues of the modern western historiography of the First World War - the issue of patriotic enthusiasm of 1914, its scopes and nature. On the basis of a wide range of primary sources, including Russian and foreign archives, memoirs and letters of contemporaries the author carries out a comparative analysis of the response to the beginning of the war of urban and rural population of Great Britain, France and Russia. Against the backdrop of numerous patriotic demonstrations in large cities, the rural population's response looked much more constrained and passive. At the same time the latter attests rather to the peculiarities of rural culture than to the absence of patriotic upsurge. The author points out that besides apparent distinctions there was a lot of similarities in the urban and rural population's reaction to the beginning of the war. This refers to an immensely successful mobilization of continental armies, a rush of volunteers to the British army, and a drop of the labor movement in all European countries. The author comes to the conclusion that the patriotic upsurge in Europe in 1914 was not founded on a momentary outburst of chauvinism, but reflected a broad popular consensus on the war.
Synergetic Paradigm of Geopolitical Confrontation in the Postmodern Era
Authors: Teplyakov S. N.
Published: June 2021

The article analyzes current state and mechanisms of geopolitical struggle in postmodern information age that has come. The author judges from assumption that entirely new postmodern society appeared with expansion of information technology, accompanied by cardinal changes in mechanisms of political power. Information technologies have become one of the most important factors contributing to the transformation of modern society from industrial to informational (post-industrial). In modern conditions, ensuring national and global security is a comprehensive process that includes not only measures to ensure information and economic security individually, but also such an integrated component as providing both information and economic security. The author suggests that modem geopolitical confrontation is carried out based on the synergetic paradigm. The main tool is information and energy influence on enemy system weaknesses using information space control, organizing negative information campaigns and applying economic sanctions. If the main focus of geopolitical struggle in modern era was forced expansion of the territory, in information postmodern age control over economic and information space has become priority among forms of geopolitical struggle. Military expansion of modern era becomes substituted by information and economic expansionism of postmodern using synergetic paradigm of geopolitical confrontation in order to control and capture the opponent's political space.
Philosophy and Sociology Studies
Authors: Kravchenko S. A. , Shestopal A. V.
Published: June 2021

Philosophy and Social science school of MGIMO has received both nationwide and international recognition. The traditions of the school were laid by two highly respected scientists and science managers, George P. Frantsev, who was the rector MGIMO during the crucial period of its early years, and Alexander F. Shishkin, who was the founder and head of the Department of Philosophy. The former belonged to one of the best schools of antic history studies of the Petersburg (Leningrad) University. Frantsev made a great contribution to the restoration of Russian social and political science after World War II. After graduating from MGIMO, he worked at the Foreign Ministry of USSR, and then served as a rector of the Academy of Social Sciences and chief-editor of the journal "Problems of Peace and Socialism" in Prague. He consistently supported MGIMO scientists and recommended them as participants for international congresses and conferences. Shishkin was born in Vologda, and studied in Petrograd during 1920s. His research interests included history of education and morality. He was the author of the first textbook on ethics in the postwar USSR. Other works Shishkin, including monograph "XX century and the moral values of humanity", played a in reorienting national philosophy from class interests to universal moral principles. During thirty years of his leadership of the Department of Philosophy, Shishkin managed to prepare several generations of researchers and university professors. Scientists educated by Shishkin students consider themselves to be his "scientific grandchildren". The majority of MGIMO post-graduate students followed the footsteps of Frantsev in their research, but they also were guided by Shishkin's ideas on morality in human relations. Philosophy and Social science school of MGIMO played an important role in the revival of Soviet social and political science. Soviet Social Science Association (SSSA), established in 1958, elected Frantsev as its president, and G.V. Osipov as a deputy president. A year later Osipov became president and remained so until 1972.

Published: June 2021

Governance and regulation at the national and international level, the management system of the leading companies in the world, forms and methods of management, and marketing, commercial and advertising work form a relatively new subject field in domestic science. These issues have been introduced into the educational process in Russian universities in the second half of the 1980s. At the MGIMO these research areas have been developed for more than 60 years. Scientific School of the Department of Management and Marketing and the Department of Management Foreign Economic Activity is oriented at the international level and focuses on the development of organizational forms and methods of management, marketing strategy, marketing, and commerce in the context of foreign trade and international activities of domestic firms and organizations on the basis of a comprehensive study of advanced management experience of leading foreign countries. In the early stages of its existence, the school was focused on methodological and practical aspects of international commerce and advertising. But gradually its research encompassed the field of management and marketing, and the scientific school in the field of international management and marketing was established on the basis of examination of relevant theories and experiences of leading foreign countries, and especially multinational companies. Originally these studies were conducted by the Department International Economic Relations of the Faculty of International Economic Relations at MGIMO. The disciplines included studies of the foreign trade operations in global markets, management of foreign economic activities in foreign countries, world commodity markets, and others. The textbook "Organization and technology of foreign trade in the capitalist market" by I.N. Gerchikova, Honored Scientist of the Russian Federation, Doctor of Economic Science, Professor, published in 1977 already contained sections on management and marketing, including the organizational structure of firms and their international marketing work, international advertising, etc. PhD. Professor F.G. Piskoppel, Ph.D. Professor S.P. Nikitin systematically analyzed forms and methods of market research, which are an integral part of the marketing activities of companies in global markets.

The Factor of Food in Biopolitics and National Security
Authors: Kravchenko S. A.
Published: June 2021

The paper examines the role of food factor in the liberal biopolitics from its birth to the present day. According to the author, the consequences of this policy of food administration are ambivalent in character. On the one hand, there are real gains in mass production of food, its delivery to the consumer, medical supervision of the implementation of its quality. However, on the other hand, the basic principles of this biopolitics - scientism, formal rationalism, pragmatism and commercialism have not allowed to solve the problems of social inequality in the access to healthy food and of illuminating the hunger. In the end of the last century the liberal biopolitics acquired globo-networked and neo-liberal character but the corresponding transition from the national to the global scale administration of food production only intensified risks and challenges of modern human nutrition. In a number of countries including Russia there appeared the problems of food security. The adopted national programs to address these challenges in a "world risk society" (U. Beck) will not solve them without fully understanding and practical implementation of the principle of the indivisibility of food security for all peoples of the world and implementation of the global food security. To achieve this, the author believes, it is necessary to abandon the "repair" of the current neo-liberal wing of biopolitics and its pragmatic and mercantilist approaches to human nutrition and pass over to a humanistic biopolitics. There offered a concrete roadmap motion to it, in particular, intending to strengthen the natural sciences and engineering for the production of food with the theoretical instruments of social sciences and humanities; to replace the outdated positivistic, scientistic postulate «knowledge - power" with the formula of ethical, humanistically oriented responsibility of scientists: "the integral knowledge of all sciences - quality food for the health of all people"; to rediscover the nature of formal rationality and its modern variations that in practice lead to the organized social irresponsibility that can be substituted by different types of value rationality, the ideology of humanism, ethics of eating healthy organic food produced in "ecologically friendly environment".
Who is Responsible for Instability in the Democratic Republic of Congo?
Authors: Sidorova G. M.
Published: June 2021

The research focuses on the problem of military-political instability in the Democratic Republic of the Congo experiencing continued armed conflict for a long time. Dozens of illegal armed groups both Congolese and foreign origin continue to destabilize situation in the eastern part of the country causing humanitarian disasters. Due to governmental weakness, economic backwardness, chronical lack of finance resources, interethnic conflicts, all-round and widely spread corruption of the authorities, the Congolese government at the moment is not able to overcome scores of problems including the problem of security. Assistanceprovided to the DRC by itspartnerssuch as, first of all, the former metropolitan country Belgium, as well as the USA, Great Britain, the Europe Union and China works only in favourof these country-donors. They are attracted by rich Congolese natural resources which the DRC remaining one of the poorest countries in the world cannot turn to advantage to the full extent because of its economic backwardness. In exchange for so-calleddevelopment programmes, expensive strategic raw material (such as coltan, wolfram, casseterit, cooper, gold, niobium, and other) is being extracted and exported from the country, in addition, often on the inequivalent basis. This is taking place for the reason that numerous mines and open-cast mines are being controlled by different illegal armed groups and not by the central government. Therefore, it turns out that in the context of a military-political crisis, for so-called partners it is more beneficial to pursue their own interests. Furthermore, western ideologists arouse "separatism-oriented" theories similar to "balkanization", in other words, a breakdown of this giant country into several independent states. The Congolese are tremulous to this issue, they try to counter such approachs and defend the territorial integrity of the DRC. However, it is not an easy task. The impediment is unsettled relations with neighbouring countries - Rwanda, Uganda and Burundi which for tens of years exploit illegally natural resources of the DRC and try to lay hold of frontier Congolese territories.

The information and communication technology revolution is broadly recognised for its fundamental role in the effective operation of higher education institutions. There is a need to understand the way in which wireless local area networks at universities are viewed by registered users, the people that develop, implement and maintain these networks, and those planning on adopting these networks. The study’s objective is to unravel the usefulness of these networks in a higher education environment to promote effective learning engagements at campuses of the University of Johannesburg in South Africa. Universities provide Wi-Fi network initiatives on campuses to create an effective learning environment, and wireless local area network connections at universities mean that Wi-Fi-enabled devices can be leveraged for educational purposes. The provision of Wi-Fi-enabled computers, mobile devices and electronic gadgets has revolutionised the realm and methods of communication, which is channelled towards improving and enhancing internet coverage on campuses and at student residences. This study explores the effectiveness of Wi-Fi networks and hotspots on campuses and at student residences to improve students’ learning engagement. The study used mixed-research methods, including a document analysis to gather information from information and communication systems and a survey to gather responses from the respondents. The findings suggest that Wi-Fi availability at universities is perceived as useful and effective since students benefit from a range of improved learning experiences, easy access to educational content, enhanced performance, and quality and education delivery.

In the work, for the first time, the method of Dual Beam Laser Sintering of polymers (DBLS) was presented, in which, instead of heating the entire volume of the polymer throughout the entire process, a second, additional laser was used for selective in terms of volume and time heating of the material. The principle of operation and the design of the prototype are presented. Using the developed station, an experiment was carried out for sintering samples from technical polylactide powder as a function of selected process parameters. It confirmed the functionality of the method and proved that the sintering process can be controlled in a fairly wide range for the proposed method. A preliminary comparison of changes in the physicochemical properties of the obtained samples in relation to the samples sintered by standard laser sintering was carried out using Gel Permeation Chromatography, Fourier Transform Infrared Reflectance and Differential Scanning Calorimetry. The experiment showed that the presented method has the potential to limit the thermal degradation of sensitive polymer materials.

Published: June 2021

We report a study presenting a physicochemical surface characterisation of the GaAs surface along the functionalisation with a high-affinity bioconjugation pair widely explored in the lifesciences: biotin and neutravidin. Combined X-ray photoelectron spectroscopy (XPS), wettability measurements and spectroscopic ellipsometry were used for a reliable characterisation of the surface functionalisation process. The results suggest that a film with a thickness lower than 10nm was formed, with a neutravidin to biotin ratio of 1:25 on the GaAs surface. Reduction of non-specific binding of the protein to the surface was achieved by optimising the protein buffer and rinsing steps. This study shows the feasibility of using GaAs as a platform for specific biomolecular recognition, paving the way to a new generation of optoelectronic biosensors.

Published: June 2021

Vinyl triflimides were only accessible recently and their chemistry is yet to be discovered. Herein, we describe a general, straightforward and atom-economical synthesis of these materials from alkynes and triflimide. A vast array of terminal and internal alkynes with broad spectrum of functionalities could be employed to generate various di- and trisubstituted vinyl triflimides regiospecifically with high to specific stereoselectivity. Moreover, the protocol could be conducted on gram scale using terminal and internal alkynes. Preliminarily attempts to probe the unknown reactivity of vinyl triflimides revealed part of its chemical properties.

The title complex [PdCl(L)] (1), is obtained from the reaction of SCS pincer ligand HL (where, HL = N,N'-di-tert-butylbenzene-1,3-dicarbothioamide) with lithium tetrachloropalladate (II) in methanol. The compound 1 is characterized by elemental analysis, FTIR, 1H, and 13C-NMR spectroscopy, UV-Vis spectroscopy, powder X-ray diffraction and X-ray crystallographic techniques. At room temperature, 1 emits luminescence light of wavelength 460 nm in the solid state upon excitation by UV light of wavelength 280 nm. The average emission lifetime indicates that, both the ligand and complex emission is fluorescence in nature and involves mainly ligand centers π-π* deexcitation. It also shows good catalytic activity towards Mizoroki-Heck and Suzuki-Miyaura cross-coupling reactions of aryl bromides with tert-butyl acrylate and p-tolylboronic acid respectively. For both type of reactions, more than 99% conversion of the substrates is found to occur for electronically activated p-nitro bromobenzene using 1 mol % of 1. Further, modern DFT calculations are performed to decipher the mechanistic insight on the preferable pathways of the Mizoroki-Heck cross-coupling reaction. Stepwise free energy of reactions for various probable reaction pathways suggest that the catalytic route has profound preference for Pd(0)-Pd(II) over Pd(II)-Pd(IV) pathway.
Management of trauma to the anterior segment of the maxilla: alveolar fracture and primary incisors crown and root fracture

Background: An injury to both the primary and permanent teeth and the supporting structures is one of the most common dental problems seen in children. Splinting is usually difficult or impossible to perform in the primary dentition (due to diminutive room size and lack of patient cooperation). Healing must, therefore, occur despite mobility at the fracture line, usually resulting in interposition of connective tissue. In some instances, infection will occur in the coronal pulp. The present study reported a case of trauma to the anterior primary teeth and alveolar bone in a four year old child. The trauma has caused fracture to the crowns and roots of the primary anterior teeth. The following case was managed in a procedure that may provide primary teeth subjected to trauma a better chance than extraction with a better prognosis. Case presentation: a 4 and a half year old child was subjected to trauma in anterior segment of maxilla. Suturing of the torn soft tissue was the first step followed by pulpotomy for the left primary lateral incisor. Fixation of the right primary central and lateral incisors was done by acid etch wire fixation. Both clinical and radiographic follow up was carried out for 6.4 years. Results: healing of the soft tissue was observed after one week and completed after two months. Fixation of the teeth continued for ten months. The fracture lines in the roots remained in position. Clinically there was no sign of any pulpal inflammation or necrosis. Radiographically, no signs of infection to the surrounding tissues could be seen, no resorption in the alveolar bone, external or internal resorption of the root did not happen also. After ten months fixation ended and the wire was removed. At that time there was normal resorption of the roots of the primary incisors in relation with the normal development of the permanent incisors. After 3 years both permanent central incisors erupted in their normal position. After 6.4 years all four permanent incisors erupted into occlusion in their normal position. Conclusion: primary teeth with root fractures and severely mobile coronal fragments can be treated by a conservative approach. The severity of the sequels is directly related to the degree of permanent tooth formation (childâ€™s age), type of dental trauma and extent of the impact.
