Une « démocratie radicale » pas si radicale ?
Authors: Cervera-Marzal Manuel
Published: October 2019

Résumé Introduite tardivement au sein de l’univers intellectuel francophone, la pensée de Chantal Mouffe fait l’objet d’un intérêt croissant. La philosophe est présentée tour à tour comme une des principales théoriciennes de la gauche radicale, comme une disciple de Carl Schmitt et comme une opposante résolue à la tradition libérale. Pourtant, de l’aveu même de la principale intéressée, Chantal Mouffe se place davantage dans le camp de la « socialdémocratie » que dans celui de la « gauche radicale », elle marque une différence fondamentale à l’égard de Carl Schmitt, et elle revendique son attachement à l’idéal libéral. Partant de ces décalages, le présent article défend l’idée que la pensée de Chantal Mouffe est perçue comme plus radicale qu’elle ne l’est réellement. Chantal Mouffe entend réformer la tradition libérale plutôt que l’infirmer.
La gestion intégrée de l’eau des retenues collinaires en Algérie : reflet d’une gouvernance territoriale en devenir ?
Authors: Boudedja Karima , Belgacem Saliha
Published: October 2019

Cet article étudie le rôle des associations d’irrigants en tant qu’acteurs indispensables de la gestion intégrée de l’eau des retenues collinaires en Algérie, avec un focus sur la wilaya d’Aïn Defla. Un projet de recherche-action mené avec l’Institut national de la vulgarisation agricole (INVA) a permis de déterminer les facteurs qui empêchent les agriculteurs de participer à la gestion intégrée de l’eau des retenues collinaires - pourtant outil de la politique de l’eau et de la stratégie de développement rural. L’article s’intéresse aux raisons des dysfonctionnements de ce type de gouvernance territoriale impulsée par les pouvoirs publics, qui promeut l’implication des agriculteurs dans des structures d’économie sociale, en lien avec les collectivités locales et des représentants des institutions publiques.
Heróis sem nome: representações sobre o espaço rural e o urbano, as escolas rurais, as professoras e os alunos (Uberlândia-MG, 1950 - 1980)
Authors: Assis Danielle Angélica , Lima Sandra Cristina Fagundes de
Published: October 2019

O objetivo deste artigo é apreender as representações produzidas pelas professoras das escolas rurais de Uberlândia-MG e pelas elites locais sobre o espaço rural e o urbano, escolas rurais, professoras e alunos. Foram consultados jornais, atas do Legislativo e das escolas rurais, livros didáticos, cartilhas, cadernos escolares, fotografias e narrativas de seis professoras. Os resultados obtidos possibilitaram-nos compreender como essas representações contribuíram para compor o papel híbrido assumido pelas professoras rurais: ora eleitas como agentes de civilização, ora desprestigiadas. Ambiguidade que perpassou também a escola rural: formalmente instituída como espaço de civilizar o homem do campo, mas, paradoxalmente, núcleo de resistência e de cultura.
A Campanha Nacional de Educação dos Cegos: uma leitura a partir da imprensa jornalística dos anos 1960 e 1970
Authors: Cardoso Fernanda Luí­sa de Miranda , Martínez Silvia Alicia
Published: October 2019

Busca-se, neste artigo, compreender as linhas de ação e o funcionamento da Campanha Nacional para Educação dos Cegos, durante as décadas de 1960 e 1970. Essa campanha integrava um ‘modelo campanhista de política social’, subordinada ao Ministério da Educação e Cultura, e atuava em linhas de ação que envolviam a difusão do livro didático; o ensino de braile no Curso Normal; a qualificação de cegos para atividades industriais; a assistência financeira; e o convênio com a Campanha Nacional de Educação Rural. A imprensa jornalística é priorizada como fonte pelas peculiaridades não proporcionadas por outras fontes ‘como a riqueza de debates, anseios e utopias dos projetos educativos’.
História do ensino superior em Mato Grosso: das iniciativas frustradas à criação de um sistema universitário
Authors: Benfica Tiago Alinor Hoissa
Published: October 2019

A fim de se visualizar a instalação das primeiras instituições de ensino superior no antigo Estado de Mato Grosso, foi necessário um olhar sobre as mudanças do campo educacional ocorridas no contexto nacional. A discussão, embasada em pesquisa bibliográfica de trabalhos memorialistas e acadêmicos, busca se concentrar nas experiências da construção de instituições de ensino superior no Estado de Mato Grosso, na década de 1960, e alcança o período da divisão do Estado, ocorrida no ano de 1977. Desse modo, expõe-se uma grade de informações que permite se entender o processo de criação da Universidade Federal de Mato Grosso e da Universidade Federal de Mato Grosso do Sul. Nesse ponto, defende-se que a porção sul do antigo Mato Grosso foi mais dinâmica do que a parte norte na promoção das primeiras escolas de ensino superior. A institucionalização de escolas de ensino superior ocorreu em um contexto nacional que favorecia o seu processo de interiorização, escolas essas encabeçadas por lideranças locais, profissionais liberais que se utilizavam do discurso da promoção da modernização regional para adquirirem poder e reconhecimento com as iniciativas empreendidas no campo educacional. Já o papel do sistema universitário era, essencialmente, a qualificação da mão de obra local.
A alternativa para o progresso: o nacionalismo-desenvolvimentista, seus intelectuais e o planejamento educacional nos anos 1960 no Brasil
Authors: Santos Lincoln de Araújo
Published: October 2019

As origens do desenvolvimentismo como projeto político e suas influências no pensamento social e educacional brasileiro aglutinaram na década de 1960 um grupo de intelectuais comprometidos com esse ideário articulados por instituições e pelo Estado. Num cenário de crise política e social, Celso Furtado, Darcy Ribeiro, Anísio Teixeira e Paulo Freire atuaram como aqueles que pensaram o Brasil com base em uma convergência de ideias que os aproximava do nacionalismo-desenvolvimentista. A análise das fontes documentais identifica nas narrativas os sinais do ideário de um projeto nacional de desenvolvimento, destacando a natureza do Plano Nacional de Educação, de 1962, e o Plano Trienal de Educação, de 1963.

Neste texto pretende-se refletir acerca de algumas mudanças na memória educacional e na pesquisa em história da educação.
Presença franciscana e supremacia jesuítica no campo da História e da História da Educação na época colonial – um diagnóstico na pesquisa historiográfica a partir da análise dos CBHE da SBHE
Authors: Sangenis Luiz Fernando Conde , Mainka Peter Johann
Published: October 2019

A análise dos anais das nove edições dos Congressos Brasileiros de História da Educação (CBHE) da Sociedade Brasileira de História da Educação (SBHE), após 20 anos de existência, fez-nos concluir que um número diminuto de pesquisas tematizou o período colonial brasileiro: apenas 26 trabalhos. A quase totalidade desses trabalhos versava centralmente sobre a atuação dos membros da Companhia de Jesus e utilizava exclusivamente fontes jesuítas, a despeito da atuação histórica, evangelizadora e educacional de outras ordens religiosas que marcaram presença no Brasil, desde o século XVI, nomeadamente a Ordem Franciscana e suas ramificações, centro de nosso interesse. O objetivo deste artigo é problematizar essa opção majoritária dos pesquisadores, atinente à demarcação temporal e à seleção das fontes historiográficas utilizadas
A constituição de um arquivo e a escrita da história da educação: do gesto artesão à prática científica
Authors: Peres Eliane Teresinha
Published: October 2019

Este artigo discute a intrínseca relação existente entre o gesto artesão de constituição de um arquivo e a escrita da história da educação. Com base na experiência de mais de uma década de trabalho ininterrupto em que se associam coleta, guarda, organização e pesquisa ‘de’ e ‘em’ um arquivo específico, apresentam-se algumas das opções que foram tomadas ao longo do processo, justificando-as e discutindo-as. Trata-se de um arquivo constituído em uma universidade pública brasileira que abriga atualmente mais de cinco mil itens inventariados. A intenção principal é demostrar que a ideia que sustentou a criação do arquivo é a de lugar de memória coletiva da infância escolarizada, da docência da escola primária/anos iniciais e das práticas sociais e escolares de leitura e de escrita e do desenvolvimento de pesquisas socialmente referenciadas

GOVERNANÇA E REDES POLÍTICAS EDUCACIONAIS: UM ESTUDO SOBRE O ESTADO DO RIO GRANDE DO SUL - RS
Authors: SCHERER Susana SCHNEID
Published: October 2019

Este estudo investiga as principais instituições privadas, com ou sem fins lucrativos, que estabelecem parcerias com os sistemas públicos de educação e/ou diretamente com escolas públicas municipais e estaduais situadas no Estado do Rio Grande do Sul (RS), a fim de desvelar algumas intencionalidades e efeitos sobre a educação pública. Com base na abordagem de etnografia de redes de Stephen Ball (2015), que prevê um aprofundamento dos dados investigativos com a coleta de informações virtuais, usaram-se como fontes diferentes sites, materiais e documentos online, visando mapear as formas de atuação destes entes e as redes de relações que estabelecem. Compreende-se que tal discussão se encaixa no quadro da governança que se manifesta, entre outros modos, pelas parcerias público-privadas, e que vem sendo promovida no contexto das estratégias do atual projeto de globalização neoliberal, como novas formas de privatização e abertura de mercados para o setor privado.
O objeto e o método da psicologia histórico-cultural
Authors: Kravtsov G. G. , Kravtsova E. E.
Published: October 2019

No presente artigo, examina-se, brevemente, a crise por que passava a Psicologia à época em que L. S. Vigotski viveu e construiu sua obra científica. Ela é identificada como a crise que envolvia a definição do próprio objeto de estudo da Psicologia. As diversas tentativas realizadas com o intuito de definir o objeto dessa nova ciência que emergia geraram inúmeras visões, por vezes até antagônicas. Essa multiplicidade de visões, identificadas como diferentes escolas de pensamento a respeito da Psicologia, acabou por transformá-la numa pseudociência, vazia de seu próprio conteúdo. Foi em meio a essa crise que Vigotski formulou e apresentou uma nova e revolucionária visão teórica que rompeu com o reducionismo então vigente. São aqui apresentadas, resumidamente, suas principais ideias e fundamentos acerca do que seria o objeto da Psicologia e sua indissociável relação com o método que utiliza.Palavras-chave: Psicologia histórico-cultural. L.S. Vigotski. Objeto e método de estudo.

Published: October 2019

O objetivo do presente artigo é examinar o significado da ideia de L. S. Vigotski de que o conhecimento é um meio cultural de desenvolvimento e as repercussões dessa ideia para a organização do ensino de matemática. Admitindo-se que se ensina não matemática, mas com a matemática, são examinadas criticamente algumas possibilidades de resposta à pergunta sobre o que se ensina ao aluno quando a matemática é entendida como um meio e não uma finalidade do ensino. Em seguida, são destacadas algumas conclusões psicológicas e pedagógicas ligadas à organização do processo de ensino de matemática, quando este campo do saber é compreendido como meio cultural de que o professor lança mão para ensinar.Palavras-chave: Teoria histórico-cultural. Pedagogia. Ensino da matemática.

Análise das dissertações publicadas pelo PPGED/UFRN, na esfera da formação docente vinculada à inclusão dos deficientes (2015-2017)
Authors: Ferreira Cavalcante Ilane , Albuquerque Judithe da Costa Leite
Published: October 2019

Almeja-se analisar as dissertações voltadas à formação docente inclusiva, defendidas entre 2015 e 2017, no âmbito do PPGED/UFRN. Elegeu-se a pesquisa exploratória, com a utilização dos levantamentos bibliográfico e documental, para a coleta de dados, e a abordagem de cunho quali-quantitativo para a interpretação destes. A fundamentação teórica encontrou embasamento nos estudos de Nunes (2001), Kuramoto (2006), Grassi (2008), Almeida (2013), Paschoarelli, Medola e Bonfim (2015). Observou-se que as 12 dissertações examinadas, apesar dos distintos contextos de análise, conversam entre si nas conclusões e nas proposições colocadas, podendo-se sintetizá-las pelo descompasso entre o ensino que vem sendo oferecido e as demandas reais dos estudantes com deficiência. Sugeriram, assim, maior investimento em formação docente, pautando-se no princípio de respeito às diferenças.

Authors: Ramos Ana , Sáez M. Paz , Rodríguez M. Ascensión , Antón M. Natividad , Gómez Jesús , Piloto Paulo
Published: October 2019

The large waste volumes globally generated have increased environmental awareness, promoting waste recycling as a sustainable construction material. This study presents a review of researches that analyze the thermal behavior of eco-friendly clay bricks incorporating organic and mineral waste materials as an addition. Many of these works also provide data related to the composition of the material, and its physical, micro-structural and mechanical characteristics. Most of eco-friendly clay units increase the porosity of the ceramic, improving the energy efficiency of masonry enclosures, reducing the clay content and the energy consumption during the fire process. The positive effects of lightweight ceramics are an opportunity to improve the fire resistance inside green buildings.

Evaluating maternal and child health indicators for the Sustainable Development Goals in 2018: what is Iran’s position?
Authors: Khatooni Elham , Akbarzadeh Isa , Abdalmaleki Elham , Abdi Zhaleh , Ahmadnezhad Elham
Published: October 2019

OBJECTIVES: Since many Millennium Development Goals (MDGs) were not achieved, countries including Iran—despite achieving some of the MDGs—need regular planning to achieve the Sustainable Development Goals (SDGs) by 2030. This article examines maternal and child health indicators in the early years of the SDGs in Iran relative to several other countries.METHODS: This study was carried out through a secondary analysis of maternal and child health indicators in Iran. The results were compared with data from other countries divided into three groups: countries with upper-middle income levels, countries in the Eastern Mediterranean region, and the countries covered by the Outlook Document 1,404 (a regional classification). Then, the relationship between these indicators and the Human Development Index was investigated.RESULTS: Iran has attained better results than other countries with respect to maternal mortality, family planning, skilled birth attendance, under-5 deaths, incidence of hepatitis B, diphtheria-tetanus-pertussis vaccination coverage, and antenatal care. In contrast, Iran performed worse than other countries with respect to under-5 wasting, under-5 stunting, and care-seeking behavior for children.CONCLUSIONS: Overall, among the 11 indicators surveyed, Iran has attained better-than-average results and seems to be improving. We recommend that Iran continue interventions in the field of maternal and child health.
Why Thirlwall's law is not a tautology: more on the debate over the law
Authors: McCombie J.S.L.
Published: October 2019

This paper reconsiders the argument first debated in the 1980s and revisited by Blecker (2016) and Razmi (2016), inter alios, that Thirlwall's law is nothing but a near-identity. It is shown theoretically and by simulation analysis that this proposition is erroneous. It is also demonstrated that Razmi's (2016) specification of the balance-of-payments-constrained growth model is problematical. The paper concludes by assessing the effectiveness of the rate of change of relative prices for export and import growth. Recent evidence provides further support for the importance of non-price competitiveness in international trade and, hence, for Thirlwall's law.
Thirlwall's law, external debt sustainability, and the balance-of-payments-constrained level and growth rates of output
Authors: Bhering Gustavo , Serrano Franklin , Freitas Fabio
Published: October 2019

Thirlwall's law, given by the ratio of the rate of growth of exports to the income elasticity of imports is a key result of balance-of-payments-constrained long-run growth models with balanced trade. Some authors have extended the analysis to incorporate long-run net capital flows. We provide a critical evaluation of these efforts and propose an alternative approach to deal with long-run external debt sustainability, based on two key features. First, we treat the external debt-to-exports ratio as the relevant indicator for the analysis of external debt sustainability. Second, we include an external credit constraint in the form of a maximum acceptable level of this ratio. The main results that emerge are that sustainable long-run capital flows can positively affect the long-run level of output, but not the rate of growth compatible with the balance-of-payments constraint, as exports must ultimately tend to grow at the same rate as imports. Therefore, Thirlwall's law still holds.
Growth transitions and the balance-of-payments constraint
Authors: Mhlongo Excellent , Nell Kevin S.
Published: October 2019

This paper re-evaluates the recent criticisms of ‘Thirlwall's law’ against the literature on growth transitions. The unpredictable nature of growth transitions in developing economies suggests that the evidence derived from single-regime regression models, on which critics have based most of their arguments, is only suggestive about the long-run causes of growth. A rigorous test of Thirlwall's law requires a more in-depth analysis of turning points in a developing country's growth performance, and whether the growth law accurately predicts the sustainability of growth transitions. These arguments are illustrated with an application to South Africa over the period 1960–2017. The results show that it is misleading to evaluate Thirlwall's law across a single regime. Once regime shifts are controlled for, the growth law accurately predicts South Africa's growth performance during 1977–2003, and sheds light on the sustainable and unsustainable nature of growth transitions across the sub-periods 1960–1976 and 2004–2017, respectively. Since the literature on growth transitions identifies a competitive exchange rate as an initiating source of growth, rather than an individual long-run determinant, the omission of the level of the real exchange rate from the original growth law should not be regarded as a major weakness.
New Structuralism and the balance-of-payments constraint
Authors: Porcile Gabriel , Yajima Giuliano Toshiro
Published: October 2019

Structuralists and Post-Keynesians share the perspective that in the long run economic growth is shaped by the income elasticity of exports and imports, and that such elasticities are a positive function of the degree of diversification and technological intensity of the pattern of specialization. Since the mid 1970s, New Structuralists began to stress the role of two sets of variables in driving the pattern of specialization: a stable and competitive real exchange rate, and the relative intensity of innovation and diffusion of technology in the center and periphery. In this paper we modify the balance-of-payments-constrained growth model to include these two sets of variables. The model provides a mechanism that ensures the validity of the original Thirlwall perspective, namely that adjustment to the balance-of-payments-constrained equilibrium takes place through changes in the rate of growth of aggregate demand rather than through changes in relative prices. In addition, it shows that a macroeconomic policy aimed at sustaining a competitive real exchange rate is a necessary complement to an active industrial policy for fostering international convergence.
Is Indonesia's growth rate balance-of-payments-constrained? A time-varying estimation approach
Authors: Felipe Jesus , Lanzafarne Matteo , Estrada Gemma
Published: October 2019

This paper analyses the performance of Indonesia's economy since the early 1980s using Thirlwall's balance-of-payments-constrained (BoPC) growth model, estimated in state-space form to take account of the varying nature of the income elasticities of demand for exports and imports. Results indicate that after peaking in the mid 1980s at above 10 percent, Indonesia's BoPC growth rate has declined significantly, to about 3 percent in recent years. This is the result of changes in the three components of this growth rate: the income elasticities of demand for exports and imports, and the growth rate of world income, all three significantly lower. Especially worrisome for Indonesia's future is the decline in the income elasticity of demand for exports, a variable that summarizes the non-price competitiveness of its exports. This is the consequence of the lack of progress in upgrading the export basket and increasing its sophistication, with natural resources and low value-added manufacturing still dominating the country's exports. Focusing on the two income elasticities, the analysis shows that their determinants are variables that proxy the economy's structural changes (for example, the manufacturing employment share) and within-sector productivity growth (for example, complexity of the economy, gross fixed capital formation as a share of GDP).
Evaluation of metal removal performance of rod-type biosorbent prepared from sewage-sludge
Authors: Seo Ji Hae , Kim Namgyu , Park Munsik , Lee Sunkyung , Yeon Seungjae , Park Donghee
Published: October 2019

The aim of this work was to evaluate the potential use of recycled sewage-sludge as a biosorbent for removing various metals from aqueous solution. To improve adsorption capacity and accomplish easy solid-liquid separation, the sludge was immobilized into the rod type with Ca-alginate. The removal performance was analyzed through kinetic and equilibrium studies. We conducted batch experiments examining the removal of cationic metals and anionic metals/metalloid by the rod-type biosorbent (cations: Cd(II), Cu(II), Cr(III), Fe(II), Ni(II), Pb(II), Zn(II), Mn(II), Al(III), As(III), and Fe(III); anions: As(V), Cr(VI) and Mn(VII)).The rod-type biosorbent, which was manufactured using sludge and alginate, showed higher adsorption capability for the removal of cationic metal than anionic metal. In evaluations of cation adsorption, divalent cations adsorbed more and faster than trivalent cations. The maximum uptake of Cd(II) was determined to be 67.29 mg/g, which was higher than those of other sludge adsorbents reported in the literature. In evaluations of anions, As(V), Cr(VI) and Mn(VII) were removed by different mechanisms. In this study, we simultaneously evaluated the adsorption performance of a new biosorbent for cationic and anionic metals. Our findings are expected to contribute to the commercialization of sludge-based biosorbents.
Clinical Evaluation of the Effectiveness of Glass Fiber-reinforced Composite Space Maintainer vs Band-and-loop Space Maintainer following Loss of Primary Teeth: An in vivo Study
Authors: Chunawala Yusuf , Morawala Abdul , Ambiye Arti , Jain Kapil , Kataria Shruti
Published: October 2019

Introduction and aim

Premature exfoliation or extraction of primary tooth may lead to loss of space due to drifting of the adjacent teeth. This may also lead to undesirable effects, such as impaction of the succedaneous tooth, overeruption of the opposing tooth, and a shift of the midline, with consequent functional impairment. It is prudent to consider space maintenance when primary teeth are lost prematurely. The current study aims to clinically evaluate the effectiveness of space maintainers comparing conventional band and loop space maintainer with glass fiber-reinforced space maintainer following loss of primary teeth in mixed dentition.

Materials and methods

A total of 30 children aged 4 to 8 years were randomly assigned into two groups – band-and-loop space maintainer (group I) and glass fiber-reinforced composite (GFRC) space maintainer (group II). Distortion/dislodgment of the loop or the fiber frame, fracture of loop or fiber frame, gingival health, and space loss were evaluated clinically and radiographically at 1, 3, 6, and 12 months interval. Gingival health was assessed by gingival index given by Loe and Silness.

Results

Based on the statistical analysis, overall success rate of group I was found to be 69.2% and of group II was 95.7% (p = 0.026), which was statistically significant.

Conclusion

The GFRC space maintainers showed an overall success rate compared with band-and-loop space maintainers.

Treatment Outcome with Implant-supported Mandibular Overdenture opposing Natural Dentition
Authors: Kar Sushil , Tripathi Arvind
Published: October 2019

Although the conventional complete denture has been a standard treatment option for edentulous patients, it may not thoroughly fulfill the esthetic or functional needs of many denture wearers. This situation is commonly encountered, especially in relation to the mandibular ridge. Over the last decade, implant-supported overdenture has emerged as a successful alternative to the more commonly used removable prosthesis. The article discusses the fabrication procedure of an implant-assisted overdenture.

Outra História Global é Possível? Desocidentalizando a história da historiografia e a história antiga
Authors: Da Silva Uiran Gebara
Published: October 2019

Este artigo traz, em sua primeira parte, uma reflexão sobre a problematização da história global como uma novidade historiográfica feita por Jurandir Malerba ao analisar seu impacto na área da história da historiografia. Ainda nessa parte, o artigo busca ressaltar a centralidade da crítica ao eurocentrismo e do impulso de desocidentalização na história global recente. Na segunda parte, com base numa comparação com os impactos da história global na História Antiga, reflito sobre os quatro pontos críticos apresentados por Malerba em suas considerações finais: o fato de objetos históricos poderem se beneficiar de uma abordagem global; a coerência narrativa e argumentativa possível aos tais objetos; os limites da expertise acadêmica para uma história global; a obsolescência prematura da história global. Na conclusão, afirma-se a singularidade da crítica desocidentalizadora na nova história global e a necessidade de os intelectuais do Sul global articularem suas histórias globais alternativas às dos intelectuais do Norte global.

Acoustic Emissions from Wind Turbine Blades
Authors: Bhargava Vasishta , Samala Rahul
Published: October 2019

Research on broadband aerodynamic noise from wind turbine blades is becoming important in several countries. In this work, computer simulation of acoustic emissions from wind turbine blades are predicted using quasi empirical model for a three-bladed horizontal axis 3 MW turbine with blade length ~47 m. Sound power levels are investigated for source and receiver height of 80 m and 2 m above ground and located at a distance equal to total turbine height. The results are validated using existing experimental data for Siemens SWT-2.3 MW turbine having blade length of 47 m, as well as with 2.5 MW turbine. Aerofoil self-noise mechanisms are discussed in present work and results are demonstrated for wind speed of 8 m/s. Overall sound power levels for 3 MW turbine showed good agreements with the existing experiment data obtained for SWT-2.3 MW turbine. Noise map of single source sound power level, dBA of an isolated blade segment located at 75 %R for single blade is illustrated for wind speed of 8 m/s. The results demonstrated that most of the noise production occurred from outboard section of blade and for blade azimuth positions between 80° and 170°.

Authors: Safyanu Bashir Danjuma , Abdullah Mohd Noor , Omar Zamri
Published: October 2019

This paper reviews various power device components of solar-powered aircraft such as photovoltaic (PV) cells, maximum power point tracker (MPPT) and rechargeable batteries. The various power device components were highlighted, and the ones applicable to aircraft were analyzed, based on criteria as efficiency for photovoltaic cells; energy densities about rechargeable batteries; and maximum power point tracker on quick response to achieve maximum power point on I-V curve. Emerging technologies like photovoltaic cells, thin film cell, organic photovoltaic cell, multi-junction cell and silicon quantum dot cell, with the future potential of high efficiencies that can be used in solar-powered aircraft, were all examined. Regarding battery technology, Lithium-air battery (Li-air) was reported as having great opportunities for high energy densities capable of improving the efficiency of the solar-powered aircraft, for the greater prospect of the aviation industry. The design of efficient power device for solar-powered aircraft application is proposed. Gallium Arsenide (GaAs) solar cells were used because of its high energy conversion efficiency of 30 to 40%. A smart and intelligent MPPT Artificial Neural Network (ANN) is chosen because of its efficiency in partial shading and fast response and speed. The Li-air rechargeable battery is proposed because of its theoretical energy density of 11680 Wh/Kg.

Introduction

Acute liver failure (ALF) is a syndrome defined by jaundice, coagulopathy (INR > 1.5) and hepatic encephalopathy in patients with no evidence of prior liver disease. Toxins and drugs are a frequent cause of ALF in children.

Material and methods

The aim of our study was to establish the causes of toxic ALF in children followed up in our hospital in the period of January 2000 to August 2018. We retrospectively studied all hospital records of patients who developed ALF after mushroom/drug exposure and had been admitted to our hospital, the main pediatric toxicology center in north-western Romania.

Results

In the last 18 years, 123 patients were admitted to our clinic with toxic ALF (89 patients secondary to mushroom ingestion and 34 patients after drug exposure). In the 2000-2012 period accidental mushroom poisoning was the leading cause of toxic ALF. Unfortunately, during the last years, voluntary drug ingestions have increased dramatically. The most commonly incriminated drug was acetaminophen (52.94%).

Conclusions

ALF in mushroom poisoning is associated with a high mortality in children, despite optimal medical therapy. This etiology was one of the most important causes of death in our cohort. The difficulty in accessing emergency liver transplantation is an obstacle common to many Eastern European pediatric centers. Fortunately, in the last 5 years the incidence of mushroom intoxications has decreased in our area. It is worrying that over the last few years there has been an increased incidence of toxic ALF after drug exposure (for suicidal purposes or due to lenient regulations for prescribing hepatotoxic medications).

Introduction

No significant regression has been reported in revision total hip arthroplasty (THA) rates despite substantial progress in implant technologies and surgical techniques. It is critical to investigate how patient demographics, THA indications, surgical techniques, types of implants, and other factors influence the frequency of early and late revision surgery. The main purpose of the present study was to evaluate the clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups.

Material and methods

The clinical data of 396 patients who underwent revision hip arthroplasty between 2005 and 2011 were evaluated in this multi-centre study. Patients were assigned to one of four revision time groups based on the interval between the index hip arthroplasty and the revision surgery (< 2, 2–5, 5–10, and > 10 years).

Results

There were significant differences among revision time groups in terms of aetiology for primary hip arthroplasty, indications for revision hip arthroplasty, and types of revision procedures. Patients with hip dysplasia more frequently received revision hip arthroplasty within two years in contrast to those with osteoarthritis. Revision hip arthroplasties due to periprosthetic infection and instability were conducted earlier compared to aseptic loosening. The overall 10-year survival rate of revision hip arthroplasty was 83.2%, and it was highest for the very early revisions (< 2 years).

Conclusions

According to our results, early revision hip arthroplasty was found to be mostly dependent on surgery-related factors rather than demographic factors. On the other hand, we observed that survival rates of very early revision hip arthroplasties are higher than late revision hip arthroplasties.
Shyness, self-presentation, adonization, and influence tactics in close relationships
Authors: Mandal Eugenia , Wierzchoń Aleksandra
Published: October 2019

Background

Empirical research reveals the difficulties that shy people must face as part of their social functioning and at-taches a pejorative connotation to shyness in the process of establishing and maintaining interpersonal rela-tions. The purpose of the study was to investigate certain aspects of social functioning of shy people: the pre-ferred self-presentation styles, readiness to adopt adonization and influence tactics in intimate relationships.

Participants and procedure

The study was performed on a group of 234 participants (113 females and 121 males), aged 18 to 35 years (M = 24.29). The following questionnaires were used: the Revised Cheek and Buss Shyness Scale, the Self-Presentation Questionnaire, the Questionnaire for Measuring the Attitude toward Adonization, and the Influence in Close Relationships between Women and Men Questionnaire.

Results

The study found that shy people use self-promotion less frequently than non-shy persons and they tend to adopt self-depreciation more often compared to non-shy individuals. Further, a high level of shyness implies a less pronounced tendency to use adonization but a greater readiness to employ hard social influence tactics in close relationships: Threats and violence, Silent treatment and sulking and Complaining and arguing.

Conclusions

Correlations between shyness, self-presentation styles, adonization and influence tactics in close relationships emphasize the role of this disposition in generating social behaviors. Shyness has a negative impact on an individual’s social functioning and relations with other people. The negative consequences of shyness are par-ticularly conspicuous in the behavior of men.

Published: October 2019

Background

Research into dieting and mindfulness has primarily focused upon how mindfulness and mindful eating affect dieting. However, the effect is bi-directional, with the process of dieting also impacting on mind-set and eating. We therefore aimed to investigate how people on different diets experience mindfulness and mindful eating. The present research aimed to explore whether or not specific weight loss diets are likely to prompt more of the elements described in mindfulness and mindful eating theory.

Participants and procedure

A community sample (N = 312) who were dieting at the time of recruitment were asked to fill in mindfulness and mindful eating measures, where commercial weight loss programmes (CWLP), low carbohydrate (LC), and intermittent fasting (IF) were used as dieting methods, as well as general healthy eating (GHE). Analyses of variance were conducted with the intention of comparing those groups in mindfulness and mindful eating, as well as their corresponding sub-constructs. The questionnaires and demographic information were provided through an online database, as well as other information relating to the diet, duration and history of dieting.

Results

The results showed intermittent fasting dieters to score higher across mindfulness and mindful eating scores, although the differences from the rest of the groups were not significant. Investigating mindful eating further through the subscales revealed that CWLP scores were significantly higher in ‘routine’ when compared to GHE. Trait mindfulness subscales displayed no significant differences, except ‘describe’, which was higher in CWLP over LC dieting.

Conclusions

Specific emphasis is given to future directions, and the potential to identify diets that are theoretically and prac-tically consistent with the theory and practices of mindfulness and mindful eating.

Abstract. Accurate determination of the optical properties of analogues for meteoric
smoke particles (MSPs), which are thought to be composed of iron-rich oxides
or silicates, is important for their observation and characterization in the
atmosphere. In this study, a photochemical aerosol flow system (PAFS) has
been used to measure the optical extinction of iron oxide MSP analogues in
the wavelength range 325–675 nm. The particles were made photochemically
and agglomerate into fractal-like particles with sizes on the order of 100 nm. Analysis using transmission electron microscopy (TEM), energy-dispersive
X-ray spectroscopy (EDX) and electron energy loss spectroscopy (EELS)
suggested the particles were most likely maghemite-like (γ-Fe2O3) in composition, though a magnetite-like composition could
not be completely ruled out. Assuming a maghemite-like composition, the
optical extinction coefficients measured using the PAFS were combined with
maghemite absorption coefficients measured using a complementary
experimental system (the MICE-TRAPS) to derive complex refractive indices
that reproduce both the measured absorption and extinction.
Spatial changes in soil stable isotopic composition in response to carrion decomposition
Authors: Keenan Sarah W. , Schaeffer Sean M. , DeBruyn Jennifer M.
Published: October 2019

Abstract. Decomposition provides a critical mechanism for returning nutrients to the
surrounding environment. In terrestrial systems, animal carcass, or carrion,
decomposition results in a cascade of biogeochemical changes. Soil microbial
communities are stimulated, resulting in transformations of carbon (C) and
nitrogen (N) sourced from the decaying carrion soft tissues, changes to soil
pH, electrical conductivity, and oxygen availability as microbial
communities release CO2 and mineralize organic N. While many of the
rapid changes to soil biogeochemistry observed during carrion decomposition
return to background or starting conditions shortly after soft tissues are
degraded, some biogeochemical parameters, particularly bulk soil stable
δ15N isotopic composition, have the potential to exhibit
prolonged perturbations, extending for several years. The goal of this study
was to evaluate the lateral and vertical changes to soil stable isotopic
composition 1 year after carrion decomposition in a forest ecosystem.
Lateral transects extending 140 cm from three decomposition “hotspots”
were sampled at 20 cm intervals, and subsurface cores were collected beneath
each hotspot to a depth of 50 cm. Bulk soil stable isotopic composition
(δ15N and δ13C) indicated that 1 year after
complete soft tissue removal and decay, soils were significantly
15N enriched by 7.5±1.0 ‰ compared to
control soils up to 60 cm from the hotspot center, and enrichment extended
to a depth of 10 cm. Hotspot soils also contained 10 % more N compared to
control soils, indicating that decomposition perturbs N pools. Our results
demonstrate that carrion decomposition has the potential to result in
long-term changes to soil biogeochemistry, up to at least 1 year after
soft tissue degradation, and to contribute to bulk soil stable isotopic
composition.
Predominance of hexamethylated 6-methyl branched glycerol dialkyl glycerol tetraethers in the Mariana Trench: Source and environmental implication

Abstract. Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are useful molecular indicators for organic carbon (OC) source and paleoenvironment. Their application in marine environments, however, is complicated because of the mixed terrestrial and marine contributions to brGDGTs. Here, we employ two dimensional (2D) ultrahigh-performance liquid chromatography-mass spectrometry (UHPLC-MS) to analyze brGDGTs in sediments from the Challenger Deep, Mariana Trench, the deepest ocean in the absent of terrestrial influence. The unique feature is the absence of 5-methyl brGDGTs, and the strong predominance of hexamethylated 6-methyl brGDGT (IIIa') (73.4 ±2.4 % of total brGDGTs). The brGDGTs-reconstructed pH is 8.22 ± 0.07, close to seawater pH. This, combined with characteristics of δ13C (− 19.82 ± 0.25 %), OC / TN ratio (6.72 ± 0.84), branched and isoprenoid tetraether (BIT) index (0.03 ± 0.01) and the acyclic hexa-/pentamethylated brGDGTs ratio (7.13 ± 0.98), strongly suggest that brGDGTs are of autochthonous products from benthic bacteria or planktonic bacteria. The compiling of literature data reveals that enhanced fractional abundance of hexamethylated 6-methyl brGDGTs is common in diverse continental margins when the marine influence became intensified. This may reflect an adaption of brGDGTs-producing bacteria to weak alkaline seawater and low ambient temperature. Based on the global dataset, the cross plot of acyclic hexa-/pentamethylated brGDGTs ratio and fractional abundance of brGDGT-IIIa' is an effective approach to distinguish the terrestrial vs. marine provenance of brGDGTs.
