Background

Muscle satellite cells (SCs) are crucial for muscle regeneration following muscle trauma. Acute skeletal muscle damage results in inflammation and production of reactive oxygen species (ROS) which may be implicated in SCs activation. Protection of these cells from oxidative damage is essential to ensure sufficient muscle regeneration. The aim of this study is to determine whether SCs activity under conditions of aseptic skeletal muscle trauma induced by exercise is redox-dependent.

Methods/design

Based on their SCs content in their vastus lateralis skeletal muscle, participants will be classified as either high or low respondents. In a randomized, double-blind, crossover, repeated measures design, participants will then receive either Placebo or N-acetylcysteine (alters redox potential in muscle) during a preliminary 7-day loading phase, and for 8 consecutive days following a single bout of intense muscle-damaging exercise. In both trials, blood samples and muscle biopsies will be collected, and muscle performance and soreness will be measured at baseline, pre-exercise, 2- and 8-days post-exercise. Biological samples will be analyzed for redox status and SCs activity. Between trials, a 4-week washout period will be implemented.

Discussion

This study is designed to investigate the impact of redox status on SCs mobilization and thus skeletal muscle potential for regeneration under conditions of aseptic inflammation induced by exercise. Findings of this trial will provide insight into i) molecular pathways involved in SCs recruitment and muscle healing under conditions of aseptic skeletal muscle trauma present in numerous catabolic conditions and ii) if skeletal muscle’s potential for regeneration depends on its basal SCs content.
Multiple asystole events in a patient undergoing total knee arthroplasty - a case report
Authors: Burgdorff Anna-Maria , Flöther Lilit , Wohlrab David
Published: May 2019

Background: Unexpected cardiac arrest in patients during surgery is associated with high mortality. Reasons are often multifactorial and unclear.
Case presentation: This case report describes a patient who developed reversible asystole during knee surgery under general anaesthesia. All diagnostic cardiac examinations were unremarkable. After surgery, the patient showed no further symptoms.
Conclusion: To prevent cardiac arrest due to non-cardiac reasons, patients with a high risk for asystole caused by vasovagal reflex or by pain need to be identified. Preoperative conditions such as hypovolemia need to be improved prior to surgery, and additional monitoring should be used. Further investigations to determine the influence of non-cardiac disease and long-term medication are necessary.

Authors: Xu Yupeng , Qu Yuan , Suo Yan , Gao Jian , Chen Xia , Liu Kun , Xu Xun
Published: May 2019

Purpose

To assess the changes in individual retinal layer thickness and visual function associated with gains in visual acuity after an intravitreal conbercept injection in the diabetic macular edema (DME) on spectral domain optical coherence tomography (SD-OCT) and microperimetry during 1-year follow-up.

Methods

Retrospective observational study. Twenty patients with clinically significant DME in the study eye were imaged by SD-OCT every three months and MP1 microperimeter in the third month while receiving anti-VEGF (conbercept) treatment. In each patient, seven retinal layers were segmented in 98 scans covering a 6mm×6mm area of the macula at baseline and during 1 year of treatment. An automatic, full-threshold microperimetry of the central field (10°×10°, 40 stimulated points) with the MP1 microperimeter. Thickness and microperimetry changes were quantitatively measured and evaluated for their correlation with increases in visual acuity.

Results

Although thicknesses of the inner nuclear layer (INL) and the outer nuclear layer (ONL) were reduced the most after treatment (p< 0.05), decreases of the ganglion cell layer (GCL) (r = 0.591, p= 0.006) and inner plexiform layer (IPL) (r= 0.663, p= 0.001) in central subfield area was associated with BCVA gain, and had the best estimation of BCVA gain (adjust R2=0.544). Mean macular sensitivity in the central subfield was also well correlated with BCVA gain (r=0.531, p=0.016).

Conclusions

Neural recovery occurred after the resolution of edema during conbercept treatment, due to the decreases in GCL and IPL associating with gains in vision and improved microperimetry.
A weak fault diagnosis method for rotating machinery based on compressed sensing and stochastic resonance
Authors: Shi Peiming , Ma Xiaojie , Han Dongying
Published: May 2019

Vibration signals used for rotating machinery fault diagnosis often constitute large amount of data. It is a big challenge to extract faults feature information from these data. Recently, a new sampling framework called compressed sensing has been proposed, which enables the recovery from a small set of measured data if the signals are sparse or compressible. In reality, the sparseness of the signals is not very well due to noise, so it is difficult and unavailing to recover the whole signal. Thus, a new mechanical fault diagnosis method is proposed in this paper. First, the machine fault vibration signals are pretreated by stochastic resonance. By this way, the fault signal drowned by noise is amplified and the sparseness of the signals is enhanced, which make it possible to apply compressed sensing. Second, fault features are extracted directly from the compressed data without recovering completely, which reduces the dimensionality of the measurement data and the complexity of algorithm. Finally, the effectiveness of the proposed method is proved by the experiments.
Implementation of new high efficient input parallel output series partial power DC-DC converter for solar photovoltaic partial shading conditions
Authors: V. Surendar , U. S. Ragupathy
Published: May 2019

The proposed research suggests an improvised performance which is efficient and a reliable converter as a reasonable solar photo Voltaic (PV) approach. The proposed research helps in elevating the performance levels so that power extraction is maximized from the respective PV arrays specifically during the case of limited shading. In order to track the maximum amount of power from every solar PV string, connection of DC-DC converters is done amid the solar PV strings. By doing so, maximum power output can be ensured by the operation of each string irrespective of the occurrence of variation in the solar radiation amongst diverse strings. Usually, the DC-DC converter that would be employed for this purpose would process the string’s power completely. This Full Power Processing (FPP) architecture gives rise to extreme losses of conversion. Hence, the suggested work propound a Partial Power Processing (PPP) that processed a part of the total system power, while the rest of the power is straight away delivered to the output side, thus provides high conversion efficiency when compared to the existing DC-DC FPP converters. An input parallel output series structure having a novel Non-Isolated Partial Power Processing topology (NIPPP) is recommended and the operation’s details are elucidated depending on the operating principle. For the purpose of evaluating the performance of the converter, Matlab Simulink environmental platform are carried out. The closed loop prototype experimental approach is also carried out with the improvement of efficiency compared to conventional it appears in efficient manner.

Authors: Tiryaki Talha , Karacan Tolga , Yesiralioglu Seyma , Ozyurek Eser , Kiyak Huseyin , Oral Engin
Published: May 2019

Objective: Owing to its high sensitivity and specificity, and because it is widely available, transvaginal ultrasonography is the first-line imaging test of choice used for the diagnosis of endometriosis. Ultrasonographic findings evaluated in conjunction with symptoms and signs may improve the diagnosis of endometriosis. Therefore, we hypothesized that transvaginal ultrasonography combined with physical examinations performed by physicians could predict endometriosis better in patients with symptoms suggestive of endometriosis compared with asymptomatic patients at presentation.Study Design: In this retrospective cohort study, the first subjective impression obtained from the history, physical examination, and transvaginal ultrasonography performed by the physician during the first visit in the outpatient clinic was taken into consideration. Patients who underwent surgery with the indication of ovarian mass were divided into two groups according to their admission types; symptomatic and asymptomatic.Results: The number of patients reported to have endometriosis histopathologically was 138;132 were in the premenopausal period (symptomatic group n=101, asymptomatic group n=31) and 6 were in the postmenopausal period (symptomatic group n=1, asymptomatic group n=5). The positive predictive value and positive likelihood ratio of the combination of pelvic examination and transvaginal ultrasonography in premenopausal symptomatic and asymptomatic patients, and postmenopausal symptomatic and asymptomatic patients were 97.8%, 11.5; 47.3%, 6.9; 25.0%, 4.6; and 11.1%, 2.3, respectively.Conclusion: The diagnostic performance of transvaginal ultrasonography in combination with physical examination in patients with asymptomatic endometriosis cannot reach the diagnostic accuracy of physical examination combined with transvaginal ultrasonography in patients with endometriosis who present with symptoms.

Authors: Ogundipe Adeyemi A. , Ogunniyi Adebayo , Olagunju Kehinde , Asaleye Abiola J.
Published: May 2019

Introduction:

Poverty is a common phenomenon in the world today, with a vast dominance in Africa, with Nigeria not exempted. This paper analyzes gender perspective of income inequality and poverty among sample of rural households in Southwest, Nigeria. Gini coefficient, Foster-Greer-Thorbecke (FGT) and Logistic regression model was used to assess the objective of the study.

Methods:

The poverty line stands at N15271.83 ($76.74), with more than half (53.71%) of the male population considered poor while the female poor population stood at 47.22%. However, the study found that income inequality was lower among the male respondents than the female counterparts. A number of explanatory variables were considered, the following - educational years, household size, farming experience, market distance, extension access, credit access and member of social group represent important poverty drivers in the study area.

Results and Conclusion

The study therefore suggests that reducing the number of dependent household members and ensuring ready availability and equal access to institutional facilities, basic amenities, credit facilities, and human capital development of rural households are some measures that could curb the menace of poverty.

O curso de artes visuais do PARFOR-UNEB: breves notas sobre a importância das políticas educativas participativas
Authors: Trigo Isa Maria Faria
Published: May 2019

Este ensaio pretende analisar alguns dos caminhos percorridos pelos programas de formação de professores da educação básica oferecidos pela Universidade do Estado da Bahia, desde os anos de 1990. Abordam-se três grandes programas: o Programa Intensivo de Graduação (Rede UNEB 2000), o Programa de Formação de Professores do Estado (PROESP) e, desde 2010, o Plano Nacional de Formação de Professores da Educação Básica, também designado Plataforma Paulo Freire (PARFOR). Analisando de forma mas aprofundada este último, o artigo constitui uma tentativa de descrever as estratégias de resistência dos grupos de trabalho, face à implementação do programa, evidenciando como as soluções criativas podem emergir a partir da dificuldades e impasses dos processos. Neste sentido, os lugares de tensão e de incompletude podem ser meios de transformação e de evolução, tanto no plano das práticas, como das tomadas de decisão políticas. O texto argumenta, finalmente, que as políticas foram obrigadas, no decurso deste processo, a responder às exigências e realidades das populações e instituições envolvidas.

Filiados e militantes partidários: perfis da filiação partidária numa perspetiva comparada
Authors: Espírito Santo Paula , Costa Bruno Ferreira
Published: May 2019

O ponto de partida deste estudo reside na constatação de que o declínio da mobilização partidária e socialização política é de grande importância para entender melhor a democracia e como ela pode sobreviver. A nível nacional, a atividade dos membros dos partidos tem características significativas, que estão profundamente assentes na cultura política do país. A nível individual, o ativismo partidário é uma missão específica para cada pessoa. A filiação partidária não é apenas parte de sua história de vida única, mas também serve como um elo de ligação na cadeia de sustentabilidade do partido. O estudo da mobilização partidária e a socialização política carecem de maior desenvolvimento no contexto português, particularmente o estudo da escolha da atividade dos membros do partido. O principal objetivo deste artigo é o de identificar, numa perspetiva comparada, os traços sociodemográficos básicos assim como um conjunto de atitudes político-ideológicas essenciais distintivos de membros partidários de três partidos Portugueses principais com assento parlamentar (Partido Socialista – PS, Partido Social Democrata Militantes; partidos; filiados partidários; democracia; socialização PSD e Centro Democrático e Social/Partido Popular – CDS/PP). A metodologia deste estudo baseia-se na técnica da sondagem, validada na pesquisa do projeto MAPP (Working group on Members and Activists of Political Parties). Este é um objeto escassamente analisado em Portugal (Stock et al. 1985; Lisi & Espírito Santo, 2017), sendo que os resultados esperados serão os de contribuir para identificar causalidades no que se refere à diminuição e à falta de interesse pela participação partidária, mas também política em geral, por um lado. Por outro, pretende-se contribuir para conhecer melhor, por dentro dos partidos, quem são os filiados partidários e como poderão distinguir-se dos militantes.
Pensamentos no gerúndio, como docente, artista, curadora

Apresento um relato da minha experiência enquanto produtora de trabalho artístico, curadora de exposições, analista cultural e artística. Neste artigo será dada particular relevância a duas experiências artísticas – Projeto MAMÃE, com reflexão em torno da obra Olho Mágico, e a Exposição ContidoNãoContido. A obra Olho Mágico surge como comentário autorreferencial, paródico. A transformação de uma parede cega em uma espécie de janela, como que intermedeia os possíveis diálogos entre o que se percebe como espaço interior e exterior. Na exposição ContidoNãoContido procuramos suscitar no visitante a necessidade de desconstruir criticamente a “reverência de tom forçado” frequentamente associada ao museu.

Desintegração e repetição: uma análise a partir de William Basinski
Authors: Bogalheiro Manuel
Published: May 2019

Partimos da peça musical Disintegration Loops de William Basinski. A obra, com cerca de uma hora de duração, é constituída por um ostinato que se deteriora até ao ruído e, por fim, ao silêncio. Basinski digitalizou o som de velhas bobines de loops feitas por si nos anos 80 para memória em disco; por força do pó e da oxidação, ao serem tocadas no leitor magnético as fitas começaram a degradar-se progressivamente. A reprodução do som, e o esforço para a sua preservação, implicou a sua destruição que, ainda assim, ficou gravada num novo meio. Questionam-se aqui os efeitos das migrações entre meios (analógico/digital) e a tensão entre a cristalização do simbólico pela técnica e a irredutível instabilização entrópica que daí resulta. A estrutura interna da peça acentua a noção de repetição como uma forma também instável e dinâmica que cria algo de novo. Esboça-se então uma crítica ao determinismo e ao automatismo que por vezes revestem a técnica e a tomam como um “círculo perfeito”. O percorrer dessa circunferência, com o desgaste que lhe provoca e com as hesitações e os ritmos humanos, mostra que tal círculo não é perfeito e que a “desintegração” é, afinal, metáfora da natureza humana.
Paisagens sonoras de baixa fidelidade em O som ao redor (2012) e Ventos de agosto (2014)
Authors: Porto Igor Araújo , Rossini Miriam de Souza
Published: May 2019

Partindo de dois conceitos de R. Murray Schafer (2001), de paisagem sonora e baixa fidelidade, pretendemos aproximar o autor do campo dos estudos de som no audiovisual, pois são conceitos que nos ajudam a problematizar aspectos estéticos e sonoros observáveis, especialmente, em filmes do chamado Novíssimo Cinema Brasileiro, produzidos nos últimos dez anos no país, e que se utilizam das possibilidades estéticas conferidas por novas tecnologias de captação de som e imagem, bem como de edição. Para tal, traçaremos a definição de paisagem sonora em Schafer, ressaltando o aspecto interdisciplinar do conceito. Depois pensaremos como a noção de baixa fidelidade, afastada de seu uso no senso comum, pode ser aplicada no campo da comunicação e, mais especificamente, do cinema. Por fim, faremos um piloto de análise em algumas cenas de dois filmes recentes realizados no Estado de Pernambuco, cujo trabalho sonoro ajuda a exemplificar a aproximação que se quer fazer entre os conceitos de Schafer e o campo do cinema. São eles: O som ao redor (Kleber Mendoça Filho, 2012) e Ventos de agosto (Gabriel Mascaro, 2014).

Authors: Baptista Maria Manuel
Published: May 2019

A presente reflexão procura articular as determinações centrais das atuais sociedades e culturas contemporâneas com uma conceção de tempo ocioso, indagando das suas potencialidades e constrangimentos. Para o efeito, é convocada a fenomenologia heideggereana que, em conjunto com as noções de temporalidade do dasein e obra-de-arte, nos permite fundamentar a necessidade incontornávelde uma relação ociosa com a verdade, como algo se oculta e desvela, tanto na linguagem como nos modos (im)próprios de relação do dasein à temporalidade.
USOS DO ESPAÇO, LIBERDADES E CONSTRANGIMENTOS: São Paulo, Cidade Limpa: estudo de caso
Authors: Pires Helena
Published: May 2019

As formas sensíveis que se interpõem à experiência quotidiana de circulação pelo espaço urbano encontram na publicidade exterior um dos meios mais propícios ao exercício da vida social. Porém, a publicidade exterior impõe-se numa relação dialógica nem sempre pacífica, entendida como uma ameaça à ordem (desordem) da cidade percebida. Poderá a publicidade deixar de querer afirmar o lugar da persuasão, da sedução e da poética no quadro da vida urbana contemporânea? Em 26 de Setembro de 2006, a Câmara Municipal de São Paulo, no Brasil, aprovou a Lei Cidade Limpa, visando a proibição da publicidade exterior. Desde então, uma acérrima polémica tem ocupado cidadãos, políticos, arquitetos, urbanistas, publicitários, bem como artistas, entre diversos tipos de interlocutores, na defesa de pontos de vista por vezes radicalmente irreconciliáveis. É nossa convicção que subjacente a uma tal discussão se encontram diferentes noções de felicidade, individual ou coletiva, que na sua particular aplicação ao espaço e cultura da cidade, em fase de preparação da Copa do Mundo de 2014 (em São Paulo), importa cartografar.
DIÁSPORA AFRICANA NO CEARÁ: Representações sobre as festas e as interações afetivo-sexuais de estudantes africano(a)s em Fortaleza
Authors: Langa Ercílio Neves Brandão
Published: May 2019

Este estudo de caráter etnográfico analisa as festas e as interações afetivo-sexuais de estudantes africanos e africanas residentes na cidade de Fortaleza, e as relações desses sujeitos com a sociedade de acolhida. A partir da análise das múltiplas representações existentes, encarnadas pelos grupos sociais, africanos e brasileiros, articulo gênero, raça, classe e outras interseccionalidades. Pertencentes a diversos grupos etnolinguísticos, no cenário de migração estudantil, os africanos e africanas não estão inteirados dos limites sociais tradicionais, rompendo com as fronteiras afetivas e de sexualidade estabelecidas. Uma das ideias centrais que avanço neste artigo, é de que tais eventos constituem momentos liminares (Turner, 1974), privilegiados de interações e negociações afetivas entre a juventude africana e a sociedade fortalezense. Fruto das observações, entrevistas e conversas informais, percebo que tais interações articulam raça, etnia, classe, formato de corpo e de cabelo, que se sobrepõem e se intersectam como atributos desejáveis e atraentes, criando correlações diversas. Muitas dessas correlações revelam uma discriminação interseccional que atinge os homens e as mulheres em graus e formas distintos.

Published: May 2019

A proposta desse estudo é compreender a dinâmica institucional do Estado a partir das políticas empreendidas no campo cultural. Para isso, o mesmo se pauta pela configuração da região das Missões jesuítas-guaranis, sul do Brasil, para posteriormente apontar algumas atribuições institucionais na produção da cultura regional. Aborda noções de produção cultural, políticas e instituições culturais e em seguida toma como elementos históricos os domínios do patrimônio e da música e a atuação do Governo de Getúlio Vargas nos períodos em que presidiu o país. Através de pesquisas bibliográficas e documentais o artigo debate as políticas culturais como ações empreendidas pelo Estado em contraponto às práticas da população regional. Conclusivamente são destacadas cinco atribuições institucionais do Estado: regulação, normatização, cognição, gestão e mediação. Tais atribuições tanto podem ser vistas de maneira articulada como isoladas no contexto investigado, sendo que em ambas as condições vêm a contribuir para as pesquisas e as práticas culturais.

COMO GOVERNAR O ÚNICO TEATRO DE ÓPERA EM PORTUGAL? A incerteza permanente do estatuto do Teatro Nacional de São Carlos
Authors: Martinho Teresa Duarte , Matos José Nuno
Published: May 2019

Fundado em 1793, o Teatro Nacional de São Carlos (TNSC) é uma referência no campo da difusão e da produção de ópera em Portugal. Considerando o período entre 1974 e 2013, o presente artigo tem como principal objetivo compreender a evolução dos vários estatutos do TNSC e das lógicas que os enformam. A partir da análise de documentação jurídica, bem como de relatórios de gestão e de monografias dedicadas à história do referido teatro, é possível identificar ao longo deste período a oscilação entre dois paradigmas: o da gestão pública, que coloca a instituição sob a alçada direta do Estado, identificando neste modelo a melhor forma de assegurar o interesse público; o da gestão privada, defendendo que a satisfação do interesse público requer a indispensável participação de receitas empresariais em domínios sob responsabilidade estatal, em nome de maior eficácia orçamental. A relação entre estas duas lógicas, como será possível verificar, decorre no quadro de processos de maior amplitude, sendo indissociável de mutações nas políticas culturais e noutras esferas da sociedade.
Análise de uma ação coletiva: comunicação e mobilização em defesa do direito de escolha da mulher em relação ao parto
Authors: Gonçalves Aline , Silvestrin Celsi
Published: May 2019

Neste artigo são apresentados alguns dos resultados da pesquisa Da Internet às Ruas: a Marcha do Parto em Casa. Com base na discussão a respeito do papel da comunicação e dos atores coletivos na sociedade, o trabalho teve por objetivo observar se as pessoas envolvidas na defesa da humanização do parto conseguiram, utilizando ferramentas disponíveis na internet e acionando a mídia, ampliar a visibilidade social do tema. Realizou-se uma análise documental, cujo corpus foi composto por peças de comunicação relacionadas ao conflito estabelecido entre as pessoas que defendem o parto humanizado e o Conselho Regional de Medicina do Rio de Janeiro (Cremerj). A análise de conteúdo de uma página de evento no Facebook, usada para a organização da Marcha, confirmou que o site teve papel central nesse processo, por isso a metodologia de estudo foi focada nas apropriações tanto da internet quanto das redes sociais. Para esclarecer dúvidas e confirmar ou refutar hipóteses, foram realizadas entrevistas em profundidade com algumas das articuladoras da ação coletiva. Verificou-se que as pessoas envolvidas na mobilização se uniram para defender uma causa — o direito de escolha da mulher em relação ao parto. Para isso, as ativistas realizaram ações de comunicação e mobilização, visando à sensibilização da sociedade para que essa exija o cumprimento dos direitos das gestantes e mudanças do modelo de assistência obstétrica no Brasil.

Published: May 2019

Boston University Goldman School of Dental Medicine (GSDM), in collaboration with Boston University School of Medicine, introduced the Oral Health Sciences (OHS) pipeline program in 2005 to enhance the academic preparedness of students from underrepresented minority (URM) groups for dental school admission. The aim of this study was to evaluate the OHS program's success in preparing URM students for dental school, as measured by acceptance to dental school and performance in the first and second years. Data on 2005‐15 program enrollees were collected from admissions records, the registrar, and the Office of Institutional Research on students' race/ethnicity, undergraduate and OHS grade point average (GPA), and Dental Admission Test (DAT) scores. Acceptance to dental school and performance at GSDM for non‐URM OHS graduates, URM OHS graduates, and non‐OHS dental students were compared. A total of 55 URM students completed the OHS program during this period, with 49 successfully matriculating to a dental school in the U.S. and 33 attending GSDM. Average OHS GPA was higher for those URM students accepted to dental school than for those who did not gain admission (3.36±0.30 vs. 2.94±0.19). Evaluation of the academic performance of URM OHS students in the first year (p=0.13) and second year (p=0.88) at GSDM showed that these students performed as well as the non‐OHS and non‐URM OHS students. These results demonstrate that the OHS master's program serves as a successful credential‐enhancing program for dental school applicants, while also serving as a pipeline to increase the number of qualified applicants from URM groups.
Measuring the Level of Reflective Ability of Predoctoral Dental Students: Early Outcomes in an e‐Portfolio Reflection
Authors: Gadbury‐Amyot Cynthia C. , Godley Lance W. , Nelson John W.
Published: May 2019

Learning to evaluate one's own skills through reflection and self‐assessment prepares dental graduates for successfully navigating an ever‐changing work environment throughout their careers, but the search continues for the most effective teaching and assessment strategies to develop students' skills in these areas. Beginning with the Class of 2017, the University of Missouri‐Kansas City School of Dentistry adopted e‐portfolios as a programmatic (four‐year) global assessment measure in the predoctoral dental program, in large part to encourage the development of reflection. The aim of this study was twofold: to examine interrater reliability among raters when scoring reflective writing using a validated measure of reflection skill and to analyze students' level of reflective ability as fourth‐year dental students. Reflections of all 102 students were independently evaluated by the three investigators using a grading rubric based on Bain's 5 Rs (reporting, responding, relating, reasoning/deconstructing, reconstructing). Intra‐class correlation was used to assess interrater reliability among the three raters, resulting in a good range for agreement (ICC=0.67; 95% CI 0.54, 0.77). The results showed that the majority (70%) of the global reflections were rated at Level 2 (responding) and Level 3 (relating). Approximately 15% of the global reflections reached Level 4 (reasoning/deconstructing), and only one was rated at the highest level (Level 5, reconstructing). This study confirmed that reflection and reflective writing were difficult for students to accomplish. As a result, curricular enhancements at this school have been implemented that involve both faculty and student development. Ongoing evaluation is required to determine if those changes result in higher levels of reflective ability. The positive outcomes of reflection and writing warrant continued examination in how to improve this educational strategy across the curriculum.

Published: May 2019

The present paper bears discussion in nature and doesn’t claim for any scientific evidence.The purpose is to identify which classification of acetabular defects currently is the most employed in revision hip joint arthroplasty, and how precise this classification reflects the true defect severity and gives the objective grounds for selection of revision implants.Materials and methods. The authors conducted literature analysis in PubMed and eLIBRARY for the last five years. 170 publications in English, German and Spanish languages as well as 15 works in Russian language dedicated to classification of acetabular defects were selected.Results. W.Paprosky classification was found to be the most applicable, namely, in 65,9% of foreign publications and in 100% of Russian papers. AAOS classification was used in 22.9% of cases, Gross and Saleh — in 4.1%, Gustilo and Pasternak — in 1.2%. 5.9% publications reported use of two classifications. The reasons for Paprosky classification popularity is the possibility to evaluate defect basing on standard pelvis x-rays in preoperative stage as well as in retrospective research. At the same time, according to literature, the confidence of Paprosky classification (accuracy of correspondence to intraoperative findings) varies from 16 to 66% for different areas of acetabulum, and during reliability assessment (consistency between different specialists) kappa coefficient varies from 0.14 to 0.75 depending on experience of the specialist and specifics of the defect. One of the possible reason for discrepancies in assessment of defect grade are the iatrogenic and posttraumatic changes of the acetabulum. Nevertheless, Paprosky classification is evolving and, considering additional parameters, like type of defect (contained or non-contained) and pelvic ring continuity, it allows to create a full-fledge algorithm for selection of revision implants and defect replacement which is adequate to the up-to-date surgical needs. At the same time onrush of digital technologies of 3D-visualization considerably expands our possibilities for preoperative defects assessment and offers promising potential for development of new classifications, whose benefits are yet to be evaluated.

Objective: In this study, an attempt was made to generate information based on botanical, physicochemical and HPTLC data needed for proper identification and authentication of M. emarginata and C. asiatica belonging to two different families.

Methods: Botanical study comprises of macroscopy, microscopy and powder microscopy of leaves of both crude drugs. The physicochemical parameters such as water-soluble extractive, alcohol soluble extractive and loss on drying at 105℃, total ash, acid insoluble ash, and volatile oil were determined according to standard methods. HPTLC studies of chloroform extracts of leaves of both drugs were conducted at 254 nm, 366 nm and 575 nm after derivatisation using vanillin-sulphuric acid and the results were documented.

Results: The present study reveals that microscopy and most of the physicochemical parameters of both the plant materials are different. Anatomy of the leaves showed two main characteristic differences. First plenty of trichome with trichome base and calcium oxalate crystal is common in M. emarginata, which is not observed in C. asiatica. Both plants have different venation patterns and leaf constants. The total ash content and the solubility in alcohol and water for leaves of C. asiatica are higher than that of M. emarginata. The HPTLC fingerprinting pattern obtained for both drugs are different.

Conclusion: All the results obtained from this study help in determining differences and similarities of leaves of M. emarginata and C. asiatica and thereby preventing adulteration and substitution and emphasizing the importance of standardization.

Extraction of consistent shell theory equations from 3D theory of elasticity
Authors: Zveryaev Evgeny M
Published: May 2019

Aims of research. Derivation of consistent equations of the theory of thin elastic shells without hypotheses and stress averaging over the shell thickness. Methods. Using the iterative method of Saint-Venant - Picard - Banach, the three-dimensional problem of the theory of elasticity is solved without any hypotheses. By the principle of compressed mappings, the solution converges asymptotically, regardless of the choice of the values of the initial approximation. Results. A method has been developed for integrating the spatial equations of the theory of elasticity in curvilinear coordinates for a thin shell. The presence of a small parameter allows the integration of the system of equations in such a way that the output data of the first operator is input to the next operator, etc., dividing the original complex operator into a sequence of simple integrable Picard type operators. Each equation contains terms of only one asymptotic order.
Ethnic distance among the students of Serbia
Authors: Šuvaković U
Published: May 2019

Аbstract. The paper presents the results of the research aimed at identifying changes in ethnic distance among the students of Serbia. The starting point of the study was the author’s belief that ethnic distance is a good indicator of inter-ethnic relations in multi-nation society and an indicator of conflict potential, and that ethnic distance is more stable provided social stability and open society. Ethnic distance was studied in the longitude project among Serbian students at the University in Kosovska Mitrovica five times in 2009-2016, twice - among the students in Belgrade (2010, 2014), and once among the Albanian students in Priština (December 2016 - January 2017) based on the modified Bogardus scale, a part of the questionnaire in the students’ native language and a number of surveys. The paper presents the results of the measurements of values constituting ethnic distance. The data reveal that the largest ethnic distance among Serbian students in Belgrade and in Kosovska Mitrovica was with the Albanians, while the smallest ethnic distance - with the Russians and Greeks. Among the Albanian students, the largest ethnic distance was with the Serbs, Romani and Russians, while the smallest -with the Americans and English. Certainly, the explanation should take into account the relations of these nations and official policies of their states including the self-proclamation of “Kosovo independence”, and also the positions of these nations in the period of the disintegration of Yugoslavia, wars in the former Yugoslav states and the NATO aggression on Serbia. At the same time, the ethnic distances are extremely large in the territory of Kosovo and Metohija, however, with a tendency of decline among the Serbs. During the research in 2016 - the beginning of 2017, the values of ethnic distance of the Serbian students from Kosovska Mitrovica to the Albanians and of the Albanian students from Priština to the Serbs were practically the same, especially the leading values of ethnic distance. When explaining the large ethnic distance with the Romani, it is necessary to remember about their social marginalization.
The phenomenon of metaphor in Russian language studies: from the past to the future
Authors: Kurash Sergei B
Published: May 2019

The article analyzes the tendencies in scientific views on metaphor in Russian language studies in the past and present with a forecast for the future. Different stages in the study of metaphor, starting from traditional rhetorical approach, going back to ancient rhetorics, to the recognition of the interdisciplinary status of metaphor as one of the universals of language and thinking, the mechanism of generating meanings in the continuum from word to text are identified and described. The author uses methods of explanatory analytical description, critical analysis, generalization, systematization and classification basing on works of leading representatives of traditional and modern Russian language studies (M.V. Lomonosov, A.A. Potebnya, A.N. Baranov, O.N. Laguta, V.A. Maslova, A.P. Chudinov, etc.). The prospects of linguometaphorology (linguistic study of metaphor) as an independent direction of modern linguistics interacting with text/discourse linguistics, cognitive linguistics, psycholinguistics, cultural linguistics and other relevant branches of modern linguistics are noted in the article.
