PALM CLIPPING AND NONLINEAR COMPANDING TECHNIQUES BASED PAPR REDUCTION IN OFDM-DCSK SYSTEM
Authors: R. Abdulridha Sajjad , S. Hasan Fadhil
Published: July 2021

The main drawback of the Orthogonal Frequency Division Multiplexing (OFDM) with Differential Chaos Shift Keying (DCSK) that is named (OFDM-DCSK) is the high Peak to Average Power Ratio (PAPR). In this paper, clipping and companding techniques are suggested to overcome the PAPR problem in the OFDM-DCSK system. For the clipping technique, the clipping function is applied before transmitting the signal without the need for an inverse function at the receiver side. While for companding techniques, the commanding function is applied at the end of the transmitter side and the corresponding decompanding function is applied at the receiver to recover the original signal. Different companding techniques are investigated including Hyperbolic, A-Law, and Mu-Law companding function that are compared with the Palm clipping technique. The MATLAB simulation result shows that the Mu-Law technique has the best PAPR reduction (7.22 dB) with a good bit error rate (BER) performance when the number of subcarriers is equal to 512.

Authors: Genis Helen , MacPhee Scott , Vandenbergh Nancy , Yu Chris , Andany Nisha , Chan Adrienne K , Daneman Nick , Lam Philip W
Published: July 2021

BACKGROUND: In March 2020, COVID-19 assessment centres were launched across the province of Ontario to facilitate COVID-19 testing outside of emergency departments. We aimed to study the degree to which assessment centres provide education and follow-up care for patients with suspected COVID-19. METHODS: We conducted an online survey of Ontario COVID-19 assessment centre directors between September 15 and October 15, 2020. The primary outcomes studied were the types of educational modalities employed and information conveyed, methods and frequency of test result communication, and any follow-up care that was offered. Survey respondents were also asked to provide descriptions of barriers to patient education and test communication. RESULTS: A total of 56 directors (representing 73 assessment centres) completed the survey. The most frequent educational modalities employed were educational handouts (92%), direct in-person counselling (89%), and referral to website (72%). Seventy-one percent of respondents indicated patients with positive test results would be notified, and 61% of respondents indicated that follow-up care would be offered. The most frequently reported barriers to patient education were insufficient time and high volume of tests, while the most frequently reported barriers to communication of test results were difficulty accessing online health portals and high volume of tests. CONCLUSION: The ability of many assessment centres to provide patient education is limited by both individual patient and system-level factors. Assessment centres may benefit from standardization of educational materials, improved accessibility to test results for patients in marginalized groups, and virtual pathways to facilitate additional counselling and care for individuals who test positive.

Authors: Tkachuk Natalia Vitalevna
Published: July 2021

The author has studied the sociolinguistic experience of conducting regional studies among the titular ethnic groups of Ugra. The purpose of the article is to to find out the need to study subjects with ethno-cultural content in Ugra schools by using the questionnaire survey among the indigenous small-numbered peoples of the Kondinsky district. The subject of the study is the indigenous ethnic groups of Ugra – Khanty, Mansi, Nenets. Research methods. The theoretical and methodological foundations of ethno-cultural education are studied. The work used sociological data obtained by questionnaire collection of material. 684 questionnaires were systematized on the basis of the software for processing and analyzing sociological information «Vortex». The article emphasizes the importance of preserving, supporting and using the native languages of the titular peoples of Ugra. As a result of the study, a picture describing the vitality of the indigenous languages of the study area was obtained, and the need for educational subjects with an ethno-cultural component was established. The problem of preserving native languages is acute. In the teaching the subjects with the ethno-cultural component, the motivation and ethnic self-consciousness of the participants themselves (representatives of indigenous small-numbered peoples) are important, who, by their own will, can positively influence the socio-cultural processes of ethnic communities, the linguistic stability and prospects of national languages.

Authors: Khaknazarov Saidmurod Khamdamovich
Published: July 2021

The article considers the need of educational institutions of the Khanty-Mansi Autonomous Okrug – Yugra (on the example of the cities of Kogalym and Langepas) to teach ethnocultural subjects. This problem is also relevant for the region under consideration, where the indigenous small peoples of the North of Khanty, Mansi and Forest Nenets live. The purpose of this work is to study the state of studying the native language and ethnocultural subjects in general education institutions of the Khanty-Mansi Autonomous Okrug – Yugra, the request of parents of schoolchildren from among the indigenous small peoples of the North for ethnocultural subjects. The tasks of the work are to identify the state of study of the native language and ethnocultural subjects in general education institutions and to determine the need of parents of schoolchildren from among the indigenous small peoples of the North for ethnocultural subjects. The object of the study was the parents of schoolchildren from among the indigenous small peoples of the North living in the cities of the Autonomous Okrug. The main method of our research is questionnaire. Results: just over half of respondents (50.9%) believe that teaching their native language and subjects with ethnocultural content will to some extent help preserve the traditional culture of the indigenous minorities peoples of the North. Among the respondents in Langepas, pessimistic assessments prevail; in Kogalym (68.9%), the majority of respondents believe in the role of teaching ethnocultural subjects. Only 36.8% of respondents want their children to study ethnocultural subjects at school.
The Ontological Dimension of Everyday Life in the Mythopoetic Picture of the World
Authors: Ryabchun Natalia Petrovna
Published: July 2021

The article deals with the concept of a home in traditional culture. It is argued that in the mythopoetic tradition, universal principles of creating a house were formed. This deserves attention today, because the main thesis in the concept of a home was the idea of the ontological dimension of everyday life, of the close connection of the spiritual and the material, of the connection of philosophical ideas and everyday actions. In traditional culture, everyday life was associated with the origins of being, was the sphere of application of creative forces. The object of research is the practice of building peasant houses in the medieval period, as well as in the XVIII-XIX centuries, their architecture and interior, their relationship with the surrounding landscape. The author uses general historical, semiotic and hermeneutical methods of research. The article systematizes the architectural principles of building a traditional home, which made the peasant house a prototype of the cosmos, a model of the universe. The author analyzes such structural elements of the mythological picture of the world as the tree of life, the world axis, the cross, the sacrifice, and their application in architecture. The author considers the ideas about the heterogeneity of space in the mythological culture and how they were used in the construction of the house; the function of doors, windows, gates in the symbolic structure of the house is investigated. The conclusion is made about the trinity of information, energy and matter in traditional culture.

Authors: Krasnova Svetlana Gurevna
Published: July 2021

The article is devoted to the use of the method of cinemalogy in the work of an educational psychologist with minor suspects, accused persons, defendants, recognized, in the case and under the terms set out in the criminal procedure legislation and the specifics of its application.
The purpose of the study is to determine the possibilities and psychological and pedagogical conditions for using the method of cinemalogy in psychocorrection work with underage suspects, accused persons, and defendants.
The following research methods were used in the article: analysis of scientific psychological and pedagogical literature, normative legal documents, study of the resources of educational Internet portals.
As a result of the study, an effective method of working with underage suspects, accused persons, and defendants was identified, and the factors of the formation of criminal behavior of underage children (heredity, social environment, and intrapersonal factors) were clarified. Based on the study of the psychological characteristics of underage suspects, accused persons, and defendants, the reasons for the commission of illegal actions (the desire for self-affirmation, to gain authority among peers, imitation of authority, the desire to obtain the forbidden, forbidden) are determined. The article offers methodological recommendations for organizing training sessions with underage suspects, accused persons, and defendants.
It is concluded that an important condition for the psychocorrection of these categories of minors is the work with psychoemotional states, situations that have a psychotraumatic effect on them, the correction of their thoughts and behavior. In our opinion, it is the method of cinemalogy that contributes to solving these problems, as well as changing criminal attitudes.

Fifty Shadows of Mesenteric Ischemia
Authors: Grossi Ugo , Pelizzo Patrizia , Sacchet Elisa , Grossi Ugo , Zanus Giacomo
Published: July 2021

A 66-year-old female presented to the emergency department with sudden onset of central abdominal pain irradiated to the back. Blood tests were unremarkable. Computed tomography scan showed acute focal ischaemia of small bowel loops sustained by an encircling omental band around a mid ileal loop, which was released on urgent mini-laparotomy. The ischaemic loops were covered with hot moist gauzes for several minutes until the normal luster and peristaltic wave returned. Indocyanine green fluorescence angiography confirmed sufficient bowel perfusion and viability. The patient was discharged 5 days after surgery and did not experience any symptom recurrence up to 6 months later. Mesenteric or colonic ischaemia may respectively affect the small or large intestine. The small intestine is able to compensate for a 75% reduction in mesenteric perfusion for up to 12 hours. If promptly treated, resection may be successfully avoided.

O objetivo do presente estudo foi correlacionar valores da atividade eletromiográfica dos músculos de membros inferiores de saltos verticais com valores do controle postural de mulheres ativas. Fizeram parte do estudo 28 indivíduos, sendo todos mulheres, divididas em dois grupos, onde 16 se encontravam no Grupo Handebol (GH) e 12 no Grupo Musculação. Para aquisição do sinal EMG dos músculos foi utilizado um eletromiógrafo Miotec (Porto Alegre, Brasil), com quatro canais de entrada operando na frequência de 2000 Hz, para os músculos: bíceps femoral, reto femoral, vasto lateral, e gastrocnêmico medial. Para avaliação dos saltos, utilizou-se os saltos Squat Jump (SJ) e Counter Movement Jump (CMJ), sendo usada a média dos dois melhores saltos de cada categoria. O pico do percentual da contração voluntária isométrica máxima (CVIM) na fase de impulsão de cada um dos saltos foi utilizado para as correlações em cada um dos quatro músculos avaliados. O controle postural foi avaliado através do teste de permanecer o mais imóvel possível durante 30 segundos, em apoio bipodal e unipodal direito. As variáveis referentes ao controle postural foram oriundas da média do percentual da CVIM ao longo dos 30 segundos analisados do controle postural. Para análise dos dados foi utilizado teste ''t'' para amostras independentes. Já as correlações foram obtidas através do teste de Pearson, além do critério de Malina para avaliar a força de correlação entre as variáveis. O nível de significância para todos os testes foi de 5%. Como resultados foram observados que tais grupos possuem características físicas bastante semelhantes. Contudo, é de se pensar que, em virtude de tempos de práticas e horas semanais de atividades distintas, seus músculos possuam certas diferenças funcionais e morfológicas. Assim, a plasticidade muscular sendo resposta para as entre os grupos.

Published: July 2021

O período universitário é um momento sensível para aquisição e estabelecimento de fatores de risco à saúde cardiovascular, que podem culminar no desenvolvimento de doenças cardíacas em momento futuro. No Brasil há escassez de estudos longitudinais que demonstrem alterações em fatores de risco durante a graduação. Desta forma, este estudo se propôs verificar mudanças em fatores de risco cardiovascular, observadas em universitários, após quatro anos de graduação. Trata-se de um estudo com delineamento longitudinal, em que a primeira avaliação foi realizada com 1.197 universitários em 2011 e a segunda em 2014. Os fatores de risco comportamentais: consumo de bebidas alcoólicas, consumo excessivo de bebidas alcoólicas, tabagismo e o comportamento alimentar foram obtidos por meio do questionário Youth Risk Behavior Surveillance. Também foram realizadas medidas para os indicadores, IMC, circunferência de cintura e pressão arterial. Para comparar as prevalências das categorias dos fatores de risco entre os períodos utilizou-se o teste do qui-quadrado para tendência. A proporção dos que consumiram bebidas alcoólicas 15 dias ou mais no mês passou de 2,5% para 5,2%. Os que consumiram álcool em excesso, entre 6 e 15 dias do mês foi de 5,1% para 7,2%. O consumo de duas porções diárias de fruta caiu de 25,3% para 20,7%, saladas e/ou vegetais três vezes ou mais foi de 26,4% para 20,8%, consumo de um salgado subiu de 27% para 31,6% e de duas porções de doces subiu de 14,9% para 19,9%. Foi observado também, aumento da proporção de indivíduos com excesso de peso, de 25,7% para 32,2%, com circunferência de cintura elevada, de 10,1% para 20,9% e daqueles com pressão arterial elevada, de 2% para 5,5% no período compreendido entre 2011 e 2014. Conclui-se então, que durante o período de graduação, os estudantes apresentaram modificações desfavoráveis em diversos fatores de risco cardiovascular.

Este artigo exploratório analisou a carreira esportiva de jogadoras de futsal das seleções sul-americanas, a partir de indicadores referentes à idade de início da prática do futsal, local onde se deu essa iniciação, quem as incentivou a praticar, a idade da primeira participação em campeonatos, a frequência semanal de treinos e dedicação atual ao futsal. A fim de traçar esse panorama da excelência da modalidade no continente, realizou-se um survey com as atletas das seleções de futsal feminina sul-americanas que disputaram o Campeonato Sul Americano de Futsal, de 2009, excetuando a brasileira. Buscou-se, baseado nesses indicadores, a construção de um primeiro panorama da realidade da carreira do futsal de mulheres de alto rendimento da América do Sul, bem como indicar alguns elementos predominantes nela. Este panorama indicou um contexto paradoxal, com condições de envolvimento na base em clubes e escolas, com apoio dos pais e familiares, mas marcado pela ausência de participação em competições. A maior parte das atletas não recebe remuneração para jogar e boa parte não se dedica exclusivamente àquele, exercendo outras atividades. Consequentemente, a frequência semanal de treinos pode ser considerada baixa. Nesse sentido, o futsal feminino sul-americano, ainda apresenta uma carreira de elite pouco estruturada e amadora.

Diversos estudos demonstram que a atividade física reduz a pressão arterial, porém no que diz respeito aos exercícios resistidos, seus o efeito sobre a pressão arterial (PA) são controversos. O presente estudo centrou-se em avaliar e comparar o efeito hipotensor através da monitorização residencial da pressão arterial (MRPA), depois de uma sessão de exercício resistido realizada por idosos hipertensos em dois horários distintos do dia. Participaram do estudo 6 mulheres (66,6%) e 3 homens (33,3%), com média de idade de 70 ± 5,22 anos e diagnóstico prévio de hipertensão arterial sistêmica grau 1. Os indivíduos participaram de duas sessões de treinamentos com as mesmas características, sendo uma às 8 horas da manhã de uma segunda-feira e outra às 16 horas da tarde de quarta-feira da mesma semana, compostas por exercícios resistidos, com duração média de 60 minutos, combinado por 10 minutos de aquecimento específico. A pressão arterial sistólica (PAS) e diastólica (PAD) foi obtida por equipamento oscilométrico oito vezes ao dia. As médias obtidas nas 48 horas de MRPA para a PAS e PAD não apresentaram diferenças significativas quando foi comparado o exercício às 8:00 horas com o realizado às 16:00 horas. No entanto, foi observada uma redução significativa da PAS pelo menos em um dos momentos estudados (11:00 horas) quando a sessão de exercício foi realizada pela manhã. Este fato não ocorreu quando a sessão de exercício foi realizada à tarde. Conclui-se que independentemente do período de realização dos exercícios resistidos em idosos hipertensos e destreinados, a PAS apresentou diferença quando comparada ao dia sem exercício. Além disso, no que diz respeito ao controle da PA, maiores benefícios foram encontrados quando o exercício foi praticado no período da manhã.

Na literatura existem estudos relacionados ao desempenho cardiopulmonar de corredores de rua, no entanto, nenhum deles os comparou considerando diferentes níveis de desempenho. O objetivo foi identificar o perfil cardiopulmonar no teste de esforço máximo de corredores de rua capixabas. Foram avaliados 59 indivíduos com idade entre 20 e 45 anos, classificados em três grupos homogêneos a partir de um ranking em provas de corrida de rua: elite (GE), amador (GA) e não atleta (GNA). Todos passaram por um teste cardiopulmonar de exercício (TCPE) com protocolo de rampa em esteira, sendo analisado nas fases do limiar anaeróbio ventilatório (LAV), ponto de compensação respiratória (PCR) e máximo (MÁX). Comparou-se os três grupos por análise de variância de uma via, seguida do teste post-hoc de Tukey (pGA>GNA), e entre as mulheres, GE foi semelhante a GA, diferindo apenas de GNA. Não houve diferenças entre os grupos para VO2 (L.min-1), frequência cardíaca (FC) e razão da troca respiratória (RTR), em ambos os sexos. Os dados sugerem que apesar de a capacidade aeróbia máxima e submáxima ter sido superior para os grupos com maior nível de desempenho entre os homens, para as mulheres não há diferença entre GE e GA, bem como entre GA e GNA, as variáveis mensuradas nesta pesquisa remetem a um cuidado especial para o planejamento de treinos de corrida para os diferentes grupos. Além disso, diferente do GE masculino, corredoras de rua capixaba não atingiram nível de desempenho de alto rendimento.

A fibromialgia (FM) é uma doença reumática, de etiologia desconhecida que apresenta como principal característica a dor musculoesquelética, desencadeando um ciclo de descondicionamento. A fisioterapia exerce um papel muito importante com os programas de exercícios físicos, compostos por alongamento, exercício aeróbio e exercício resistido para reverter os sintomas apresentados. Recentemente, estudos têm apontado para o fato de que os exercícios resistidos poderiam ocasionar uma redução da dor em pacientes com FM, gerando um novo questionamento sobre os efeitos do exercício resistido nestes pacientes. Com isso, este estudo teve o objetivo de investigar o efeito do treinamento resistido na redução dor em mulheres com fibromialgia. Para tanto, foi realizado uma revisão de forma sistematizada dos estudos publicados até maio de 2016 nas bases de dados eletrônicas PubMed, PEDro, Scielo e Lilacs. O levantamento dos estudos encontrados foi realizado no período de maio a junho de 2016, usando os seguintes descritores na língua inglesa: Physical Therapy Modalities, strength training, Pain, Fibromyalgia e seus equivalentes na língua portuguesa e espanhola. Após a busca, foram encontrados 85 artigos. Após a análise dos resumos, 80 artigos foram excluídos de acordo com os critérios pré-estabelecidos, restando apenas 5 estudos randomizados controlados, sendo selecionados para análise dos seus dados. Após a análise, conclui-se que o treinamento resistido reduz a dor em mulheres com fibromialgia, a partir da 8ª semana de treinamento, desde que esse seja realizado de forma continuada e orientada, com duração de no mínimo 30 minutos, com frequência de 2 a 3 vezes por semana.
O CICLISMO NA CIDADE: PEDALADAS PELA CAPITAL DO ESTADO DO RIO GRANDE DO SUL/BRASIL

Published: July 2021

Este artigo objetiva investigar como se configurou a difusão da prática do ciclismo pelos jornais porto-alegrenses no ano de 2014, quando a cidade de Porto Alegre, capital do estado do Rio Grande do Sul/Brasil, sediou jogos da Copa do Mundo de Futebol. Nesta direção, buscou-se estabelecer relações entre os discursos sobre a prática do ciclismo no tempo passado e presente. Para compor o corpus documental da pesquisa foram coletadas e analisadas reportagens de jornais que circularam em Porto Alegre no final do século XIX, e informações disponibilizadas pelos jornais Zero Hora e Correio do Povo, bem como por sites que abordavam o assunto, no período demarcado para o estudo, o ano de 2014. As evidências apontam que os jornais contribuíram na difusão da bicicleta e da prática do ciclismo no fim do século XIX, adentrando o século XX com rupturas e continuidades, e ganhando destaque no ano de 2014. Nestes diferentes períodos, através dos discursos veiculados sobre a prática, o ciclismo ganhou espaço como uma opção de lazer e de transporte, pois facilitava o deslocamento dos habitantes pela cidade, bem como por trazer benefícios à saúde. Além disso, no cenário contemporâneo, há indícios que a Copa do Mundo de Futebol de 2014 pode ter contribuído com a expansão – ainda a passos lentos – do ciclismo em Porto Alegre, uma das cidades que sediou o evento. Desta maneira, percebe-se que, ao confrontar passado e presente, os sentidos atribuídos a esta prática estabelecem relações de aproximação e reconfiguração emergentes de outro tempo e espaço social.
A COBERTURA MIDIÁTICA DOS JOGOS PARALÍMPICOS DE LONDRES/2012 NO PORTAL GLOBOESPORTE.COM

Published: July 2021

Este trabalho teve como objetivo analisar características da cobertura dos Jogos Paralímpicos de Londres/2012 no portal de notícias globoesporte.com, tendo como foco as seguintes características/categorias apontadas pela literatura como problemáticas e recorrentes na mídia: (1) vitimização/supercrip – quando as notícias enfatizam histórias de tragédias e dificuldades relacionadas com as deficiências e de superação das mesmas por parte dos atletas, tratando-os como super-heróis; (2) infantilização – quando as notícias tratam os desportistas como se fossem crianças; e (3) trivialização – quando as narrativas e ilustrações se centram em situações não esportivas. As categorias vitimização/supercrip e infantilização são problemáticas, pois tendem a reproduzir estigmas relacionados às pessoas com deficiência. Já narrativas que enfocam informações triviais não relacionadas ao esporte desperdiçam o pouco espaço que o esporte paralímpico ocupa na mídia para a promoção de uma cultura mais qualificada acerca do esporte paraolímpico. A pesquisa foi de cunho quanti-qualitativo e exploratório e teve como fonte o portal globoesporte.com. Encontramos 254 notícias tratando diretamente das Paralimpíadas de Londres/2012 e que foram publicadas durante a realização dos Jogos. Destas, 39 se encaixaram na categoria vitimização/supercrip. Sete matérias supostamente se enquadrariam no que a literatura internacional chamaria de “infantilização”. Verificamos, no entanto, que a intenção de nenhuma das notícias foi a de tratar os atletas como crianças. Localizamos 20 matérias que enfocaram em primeiro plano assuntos tais como a aparência, vida pessoal e profissão dos atletas, e não os feitos esportivos dos mesmos. Embora o número de notícias categorizadas não tenha sido quantitativamente significativa quando comparada com o número total de matérias publicadas, percebe-se a necessidade de uma maior qualificação da mídia esportiva para tratar do esporte paralímpico e dos atletas paralímpicos, enfocando menos nas suas deficiências e dificuldades e mais em suas habilidades e capacidades esportivas.

We report on a 15-year-old Ghanaian boy, who presented to a district hospital with diabetic ketoacidosis (DKA) but was diagnosed wrongly as a small bowel perforation due to typhoid fever. He presented with weakness, poor feeding, vomiting, and severe abdominal pain. General examination revealed a lethargic, drowsy, and severely dehydrated patient. His abdomen was diffusely tender more in the right ileac fossa. Investigations including complete blood count, blood smear for malaria parasites, urinalysis, and abdominal ultrasound yielded unremarkable results. Hemoglobin level was 12.4 grams per decilitre. He was diagnosed as typhoid ileal perforation and laparotomy was done, but the bowels and all other intra-abdominal organs were found to be normal. A blood glucose test was done intraoperatively, and it found very high hyperglycaemia. This led to the suspicion of DKA, which was confirmed through urine dipstick testing for high urine ketones and a high glycated hemoglobin (HbA1C) test result. He was then treated for DKA, which resolved on the second day of admission, but the surgical wound healed after twelve days.Our account emphasizes the need for testing for blood glucose in critically ill children and adolescents with suspected severe infections or acute medical conditions that require admission or surgical intervention. This owes to the fact that the clinical features of undiagnosed diabetes, especially if it progresses to DKA, are similar to those of infections and disorders managed via surgical treatment, which are rather more common in Ghana and Africa.

For these applications, gels must undergo degradation under physiological conditions. This overview summarized and discussed the various physical and chemical crosslinking methods to design hydrogels that are biodegradable. Highly versatile method to prepare hydrogels with good mechanical stability is chemical crosslinking. However, the crosslinker employed can give undesirable reactions with the bioactive substances present in the hydrogel matrix and are often toxic. So, it required to be removed from the gels before application. Physically crosslinked gels can be developed to overcome these adverse effects. Distortion due to variations in environmental conditions like presence of solute particles, ionic strength, pH, temperature and stress are the major disadvantages of reversible gels

For a formulation scientist, the dilemma of solubility is a crucial test during the product development phase that can be resolved by opting various technological strategies. Some of the strategies that are usually applied for enhancing solubility of drugs with low aqueous solubility include micronization, solvent deposition and solid dispersion. With these approaches, some advantages as well as drawbacks, are affiliated. The strategy of complexation amid all techniques, has been applied more accurately for the improvement of dissolution profile, aqueous solubility, and bioavailability of poorly soluble drug candidates. Cyclodextrin are unique cyclic carbohydrates that have been exploited as successful complexing agents having capability of forming inclusion complexes with insoluble drugs. Numerous strategies have been considered to analyze the methods for preparation of inclusion complexes. In this review, we have pursued the discussion on different complexation techniques and in a nutshell, emphasized the applications and economical/technical limitations related to these techniques.

Dust control in summer and winter periods is a topical problem associated with conducting open pit mining operations; however, at negative temperatures the additional requirements are imposed on dust suppressants. Preventive compositions are proposed, in which light and heavy gas oils, obtained from catalytic cracking and delayed coking, are used as base components. Involvement of heavy fractions allows to increase the flash point, thereby reducing the flammability of dust suppressant, improve its adhesion properties by increasing the content of polyaromatic hydrocarbons and reduce the cost of the final product. In order to improve low-temperature and adsorption properties of developed dust suppressants, heavy oil residues (cracking residue and tar) are included in their composition in various concentrations: 2-10 wt.%. Alternative compositions of dust suppressants, obtained by water emulsification of vinylated alkyd oligomer, are developed; the ability of this dispersion to form strong films on dusty surfaces is examined. The efficiency of using aqueous solution of vinylated alkyd oligomer as a summer dust suppressant is demonstrated. The results of this study include the development of new preventive compositions with improved low-temperature properties and confirmation of the theoretical part of the study by the results of performance tests on a laboratory facility.Alternative compositions of dust suppressors have been developed, which were obtained by emulsifying a vinyl alkyd oligomer (VAO) in water; the ability of this dispersion to form strong films on dusty surfaces has been studied. The efficiency of using an aqueous solution of vinyl alkyd oligomer in the summer period as a dust suppressant is shown. The results of this study are the development of new prophylactic formulations with improved low-temperature properties and confirmation of the theoretical part of the study by the results of tests of operational characteristics in a laboratory facility.
One of the ways to increase the durability of the sectional pump balancing ring
Authors: Ovchinnikov Nikolai
Published: July 2021

The article presents the results of scientific research aimed at struggling the adhesive wear of parts of sectional pumps balancing ring, where the drainage units pumping equipment of the Russian Federation underground kimberlite mines was used as an object of research. It has been theoretically proven and experimentally confirmed that if there is data on the total operating time of a sectional pump in transient modes per day, using the constructed regression model, it is possible to calculate with high accuracy the average operating time of its balancing ring unit to failure. The constructed regression model is applicable only to sectional pumps of drainage units of underground kimberlite mines in the Russian Federation. It is possible to increase the durability of the balancing ring by reducing the acceleration and deceleration time of the sectional pump; for safe operation, it should be at least 10 s. Pilot tests carried out indicate the effectiveness of the proposed method for prompt identification of the critical axial displacement of the sectional pump rotor through the vibration of the discharge tube. The introduction of this method will reduce the cost of repair work to restore the performance of parts of the hydraulic foot to a minimum.

Abstract. This article presents new data on the study of preserved wood from flooded forests in the Muya-Kuanda Basin, Eastern Siberia. On the basis of the stratigraphic position of a buried tree stump horizon, the analysis of the associated alluvial deposits and a new programme of radiocarbon dating, the chronology of formation and collapse for a Late Pleistocene pal eolake in the Muya-Kuanda Basin can be precisely determined. The accuracy of dating of geological events with the radiocarbon method and the possibility of linking them to calendrical dates is discussed. As a result of this research it is possible to connect the geochronology of the lake with archaeological sites in the Vitim Basin, both upstream and downstream along the river. The reasons for the periodic formation of substantial bodies of water in the Muya-Kuanda Basin are also discussed, with implications for decision making with regard to the modern economic development of the region.

Religious extremism has been one of the major areas of concern for communication scholars throughout the world. In Pakistan, the form of sectarian division on the ideological occasion of Muharram has always been observed. As a result, a lot of hate speech has been used on social media by the followers of Shia and Sunni sects. This study not only aims to determine a relationship between the demographics of the users who post the hateful materials on the social media regarding any sect, it also aspires to investigate whether the socio-economic background, education or gender plays any role in determining the level of hate speech against any sect. For this purpose, while drawing upon the theory of Uses and Gratification, a sample of 100 users of Facebook were surveyed through a questionnaire developed on 5- point Likert scale. It was found that the people from different sects like to post and share the sectarian hate speech. The study found that there was a strong relationship in the level of religiosity and posting of hate speech, however, the more the tilt towards religious practices, the more users post hateful speech on Facebook pages, Furthermore, it was also found that the education level and  socio- economic status also play important role in this arena; the better they live (more household income  and  more  study),  the  lesser  they  post  such  hateful  material.
Searching for Oneself on YouTube

Published: July 2021

YouTube is the preferred online platform for today’s teenagers. As such, this article explores the relationship between socialization processes in adolescent peer culture and the meanings behind the production and reception of YouTube videos by teenage audiences. Two fields of enquiry comprise the data analyzed in this article. First, through content analysis, we studied the production of videos on YouTube by teenagers between the ages of 14 and 18. The discursive construction of an audience is expressed by YouTubers through intimate identity performances using specific, dialogical, and conversational modes. The second study investigated the reception of these videos by teenagers between the ages of 12 and 19 through the use of focus groups and in-depth interviews. The results explained the way young people develop a sense of closeness with YouTubers. When examined collectively, our studies reveal how teenage YouTube practices, both as production and reception of content, constitute a twofold social recognition process that incorporates a capacity to recognize oneself in others—like figures with whom one can identify with—and a need to be recognized by others as beings of value. The “intimate confessional production format,” as we have termed it, reinforces this bond.

WE WERE FLYING up a two-lane state road, passing everyone in sight. ‘Babe, why are you driving so fast?’ I asked. ‘What’s the emergency?’

My wife looked back at me in panic, and said: ‘Something’s wrong with you, and we’re going to the hospital.’

‘OK… why are we going to the hospital?’

‘You’re not right. Here, you need to put on a mask.’

‘Why do I need a mask?’

‘The COVID-19 pandemic.’

‘Where are we going?’

She hit the gas even harder….
I Am Not a Story
Authors: Strawson Galen
Published: July 2021

‘EACH OF US constructs and lives a “narrative”,’ wrote the British neurologist Oliver Sacks, ‘this narrative is us’. Likewise the American cognitive psychologist Jerome Bruner: ‘Self is a perpetually rewritten story.’ And: ‘In the end, we become the autobiographical narratives by which we “tell about” our lives.’ Or a fellow American psychologist, Dan P McAdams: ‘We are all storytellers, and we are the stories we tell.’ And here’s the American moral philosopher J David Velleman: ‘We invent ourselves… but we really are the characters we invent.’ And, for good measure, another American philosopher, Daniel Dennett: ‘we are all virtuoso novelists, who find ourselves engaged in all sorts of behaviour… and we always put the best “faces” on it we can. We try to make all of our material cohere into a single good story. And that story is our autobiography. The chief fictional character at the centre of that autobiography is one’s self.’
