Hematological and biochemical characteristics during the transport of dog snapper Lutjanus jocu (Perciformes: Lutjanidae)
Authors: Oliveira Bruno L. , Souza Rodrigo M. , Silva Filho Jorge P. , Gomes Levy C. , Fernandes Luiz F. Loureiro
Published: March 2018

ABSTRACT The objective of this study was to evaluate stress responses in dog snapper (Lutjanus jocu) during transport by evaluating their hematological and biochemical responses. Twenty-five wild dog snapper specimens were used in the experiment (220 ± 68 g and 24.5 ± 2.5 cm total length). Blood samples were collected prior to transport (control), and fish were placed in two transport boxes, one with anesthetic and one without anesthetic. Immediately after transport and after 24 h, blood was collected from the fish that underwent each treatment (with anesthetic and without anesthetic). Biochemical and hematological results demonstrated the inefficiency of benzocaine as a stress reliever during handling and transport. Biochemical parameters revealed the effects of stress during transport, and after 24 h, glucose levels and hematological parameters (hemoglobin, erythrocytes, leukocytes, neutrophils and MCH) showed a tendency to return to control levels. This study is the first to report stress response measurements of hematological and biochemical indicators in dog snapper, representing an important basis for the planning of future experiments involving the transport and handling of this fish species.

Authors: Ribeiro Douglas Carvalho , Oliveira Marcelo Andrade Cattoni de
Published: March 2018

Resumo O presente trabalho pretende abordar de forma panorâmica o pensamento do jurista Otto Kirchheimer. Em um primeiro momento, busca-se relacionar o pensamento do jurista com a tradição da Teoria Crítica da Sociedade – conhecida também como “Escola de Frankfurt” -, cuja influência é marcante ao longo de toda sua produção acadêmica. Posteriormente, o foco residirá na crítica que Kirchheimer faz ao direito penal nacional-socialista enquanto instrumento de eliminação dos adversários políticos. Por fim, a partir da tipologia construída por Kirchheimer no texto “Justiça Política”, serão abordadas possíveis contribuições do pensamento do jurista alemão ao contexto jurídico atual.
A Criminologia Crítica no Brasil e os estudos críticos sobre branquidade
Authors: Prando Camila Cardoso de Mello
Published: March 2018

Resumo Neste ensaio exploro inicialmente os aspectos teórico-metodológicos a serem desenvolvidos para se estudar os efeitos da branquidade nos escritos da Criminologia Crítica no Brasil. Sustento que o tema racial é, enquanto efeito normativo da lógica branca, marcado pela análise do negro como o “outro racializado”, tomado como uma variável causal explicativa que essencializa a população negra, não identificando nela sujeitos políticos.
Da teoria de Chantal Mouffe à prática democrática boliviana: o pluralismo como horizonte
Authors: Fortes Larissa Borges , Aquino Sergio Ricardo Fernandes de
Published: March 2018

Resumo A teoria democrática de Chantal Mouffe apresenta críticas aos modelos tradicionais liberais (que trazem enraizadas as características modernas de universalismo e individualismo), contribuindo para a criação de um novo modelo democrático: a democracia radical ou pluralista. A partir da referida teoria e, considerando o novo constitucionalismo latino-americano e as contribuições democráticas trazidas com ele, pretende-se, no presente trabalho, responder ao seguinte problema de pesquisa: o pluralismo, a partir da teoria democrática de Chantal Mouffe, pode ser observado na prática democrática boliviana? A partir do método dedutivo, bem como das técnicas de pesquisa bibliográfica e documental, busca-se verificar os principais elementos comuns encontrados na teoria democrática de Chantal Mouffe e na prática democrática da Bolívia, desde o processo constituinte instituído em 2007, bem como com a promulgação da Constituição do Estado Plurinacional da Bolívia, em 2009. Pretende-se analisar, em um primeiro momento, a teoria da democracia radical ou pluralista de Chantal Mouffe, bem como as contribuições e críticas trazidas na referida teoria, verificando-se como o elemento “pluralidade” é considerado em tal concepção. Na segunda parte do trabalho, verifica-se o sistema democrático boliviano, em momento pré e pós a promulgação da Constituição de 2009, analisando-se, especialmente, os elementos “plurinacionalidade” e “pluralismo jurídico-cultural”. A partir dessas análises, pretende-se observar se a prática boliviana, a partir do elemento “pluralismo” (plurinacionalidade e pluralismo cultural-jurídico), corresponde à concepção teórica da democracia radical ou pluralista indicada por Chantal Mouffe.

O dilema do pensamento constitucional brasileiro: tupi or not tupi
Authors: Pereira Wingler Alves
Published: March 2018

Resumo O artigo analisa o pensamento constitucional da intelectualidade jurídica brasileira e busca compreender se este imaginário é autêntico ou apenas uma imitação de ideias importadas de países usualmente considerados mais avançados, localizados no Atlântico Norte. Por meio do método dialético e de análise de conteúdo das obras de direito constitucional mais utilizadas pelos principais cursos jurídicos do país, a pesquisa busca entender, a partir destas fontes primárias, a situação do pensamento constitucional dominante na intelectualidade jurídica brasileira. Com o marco teórico das ciências sociais e da ciência política quanto ao estudo do pensamento nacional, o trabalho aponta, em conclusão, para a sintonia entre o imaginário constitucional brasileiro e o pensamento colonial que predomina no país.
Os “imperativos da revolução de março” e a fundamentação da ditadura
Authors: Carvalho Angelo Gamba Prata de , Benvindo Juliano Zaiden
Published: March 2018

Resumo A ditadura, por mais violenta que seja, busca sua justificação na edição de normas aparentemente legítimas, que se pretendem democráticas por algum movimento retórico. O discurso sobre a “Revolução de Março” vai desde o tom panfletário até o de argumentos acadêmicos, como os escritos de Miguel Reale. Embora aclamado como um dos mais importantes juristas brasileiros do século XX, seus trabalhos e teorias, como a Teoria Tridimensional do Direito, têm sido normalmente dissociados de uma mais adequada compreensão do contexto de seu desenvolvimento. Este artigo supre esta lacuna ao localizar Miguel Reale na história. Como um dos juristas mais proeminentes para a formação do pensamento autoritário no Brasil, este artigo procura, diacronicamente, analisar o discurso de justificação da ditadura em seus textos políticos de três períodos diferentes de nossa História, investigando em que medida há continuidade nos projetos autoritários levados a cabo em nosso país.
A sociologia do campo jurídico de Bourdieu e Dezalay

Published: March 2018

Resumo O artigo visa a analisar a relação entre direito e desigualdades sociais sob a perspectiva da Sociologia do Campo Jurídico de Pierre Bourdieu e Yves Dezalay. É abordagem eminentemente téorica. No âmbito de suas categorias fundamentais, o texto perscruta a violência simbólica presente no embate por dizer o direito e, ao mesmo tempo, busca desvendar a maneira pela qual perpetuam estratégias de poder e dominação, associada às apropriações dos diversos capitais (cultural, econômico, social e simbólico).
Política e crise do capitalismo atual: aportes teóricos
Authors: Mascaro Alysson Leandro
Published: March 2018

Resumo A crise presente do capitalismo, ao mesmo tempo econômica, política e jurídica, também se faz acompanhar de uma crise de suas teorias de apoio, as quais precisam ser encaradas como problema teórico de pesquisa. Para mirar a superação dos atuais padrões de sociabilidade, o objetivo do presente trabalho é sistematizar aqueles horizontes teóricos do campo marxista que buscam se fundar na própria materialidade da reprodução do capital, apontando para suas determinações e suas contradições, revelando o caráter estrutural da crise e o problema político-ideológico da reprodução social. Assim, buscar-se-á anelar uma específica junção de alguns dos campos teóricos marxistas contemporâneos, que floresceram, quase todos, a partir do terço final do século XX. Em destaque, o referencial teórico que unirá tais campos será a crítica do direito promovida por Evguiéni Pachukanis, bem como as contribuições que Althusser construirá para a crítica da ideologia jurídica.
Reestructuraciones de deuda soberana: El debate sobre su regulación en términos de disputa por la gobernanza global
Authors: Manzo Alejandro
Published: March 2018

Resumen A partir de un análisis comparativo, este artículo muestra que la propuesta del FMI (2014) para ordenar las reestructuraciones conserva en mayor medida que la iniciativa Argentina en la ONU (2015) el status quo y, desde allí, la posición dominante en la gobernanza global de los agentes que la promovieron. Esta consideración se juzga relevante al tiempo de comprender por qué estos agentes se opusieron a la redacción de un mecanismo legal para reestructuraciones en la ONU.
De Rubens Paiva a Amarildo. E “Nego Sete”? O regime militar e as violações de direitos humanos no Brasil
Authors: Oliveira Luciano
Published: March 2018

Resumo Partindo de um conhecido caso de violência policial ocorrido no Rio de Janeiro em 2013 – a prisão, tortura, morte e “desaparecimento” do pedreiro Amarildo, o artigo questiona a tese, comum entre os militantes de direitos humanos, de que as violações desses direitos praticadas pela polícia brasileira seriam uma “herança maldita” do regime militar. Sem negar que a ditadura tenha reforçado tais práticas, o artigo explora uma questão: se de fato prisões ilegais, torturas, mortes e até “desaparecimentos” foram uma invenção do regime, como explicar que, mais de trinta anos após a redemocratização do país, tais práticas continuem acontecendo? A hipótese sustentada é a de que tais práticas, em relação às classes populares, antecedem o regime, com ele conviveram e sobreviveram ao seu fim.

Brazilian climate normals for 1981-2010
Authors: Diniz Francisco de Assis , Ramos Andrea Malheiros , Rebello Expedito Ronald Gomes
Published: March 2018

Abstract: In the last decades, especially since 2000, the natural vulnerability of Earth’s climate system has been a cause of great concern as to the status of global climate change due to the interference of natural and/or anthropic activities. Instituto Nacional de Meteorologia (Inmet), the government body officially responsible for monitoring weather and climate in Brazil, and also a member of the World Meteorological Organization (WMO), is proud to release the new edition of the climate normals for the period of 1981-2010. The new edition aims to analyze and register the climate changes that occurred during the two decades following the previous edition of 1961-1990. For that purpose, Inmet created a working group to prepare and edit these normals, as a basis of knowledge for different spheres of meteorology, aiming to strengthen the study and research of climate variability, as well as the Paris Agreement, which limits global warming to 1.5°C above pre-industrial levels. Finally, the publication intends to offer guidance, information, and assistance to the communities of climate sciences, agribusiness, and public and private institutions, both national and international. Overall, activities related to climate have expanded in practically every sphere of human life, especially in the fields of science and public policies.
Nitrogen fertilization in consecutive cycles and its impact on high-density peach crops
Authors: Ferreira Letícia Vanni , Picolotto Luciano , Pereira Ivan dos Santos , Schmitz Juliano Dutra , Antunes Luis Eduardo Corrêa
Published: March 2018

Abstract: The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype affects the vegetative growth and productive performance of peach trees. The application of N to dense peach orchards promotes a greater vegetative growth of the plants and increases the content of the nutrient in leaves. The initial production is affected by N fertilization. The recommendation of N fertilization made to date is insufficient for peach trees at high-density management systems of production.

Authors: Silva Dreid de Cerqueira Silveira da , Martins Márcio Lacerda Lopes , Santos Ariana Silva , Santos Vanderlei da Silva , Alves Alfredo Augusto Cunha , Ledo Carlos Alberto da Silva
Published: March 2018

Abstract: The objective of this work was to evaluate the crossability between cassava (Manihot esculenta subsp. esculenta) cultivars and the subspecies M. esculenta subsp. flabellifolia and M. esculenta subsp. peruviana. Plants from the BRS Jari, BRS Formosa, BRS Verdinha, and BGM 2050 (Equador 72) cultivars were crossed with the two subspecies. During flowering, at pre-anthesis, pistillate flowers were covered with a nylon bag and staminate flowers on the same inflorescence were emasculated. The staminate flowers were collected and placed in flasks previously labeled and sterilized with alcohol; some fresh flowers were stored at room temperature due to asynchronous flowering. The crosses were made between 10 a.m. and 2 p.m. After pollination, the flowers were covered again. Evaluations were made from the moment of pollination to the dehiscence of the fruit. Of the total flowers pollinated, 38% were fertilized, and 504 developed fruits and 816 produced seeds were observed. As a male parent, M. esculenta subsp. flabellifolia is more efficient in crosses with M. esculenta subsp. esculenta and may be recommend for controlled crosses. The crosses between the cassava cultivars and M. esculenta subsp. flabellifolia and M. esculenta subsp. peruviana produce viable seeds.

Published: March 2018

Abstract: The objective of this work was to evaluate the interaction between genotypes and environments for grain yield of common bean (Phaseolus vulgaris) lines and cultivars with potential for use in family farming systems. Data from value for cultivation and use tests, carried out in 20 environments in the state of Goiás, Brazil, were analyzed in two cycles (2007/2008 and 2009/2010) in the dry, rainy, and winter crop seasons. Each test consisted of 15 genotypes from the carioca, purple, and rosinha common bean commercial groups. The experimental design was randomized complete block, with three replicates. The methodologies used to test the stability and adaptability of the genotypes were the one of Lin & Binns, of Cruz, the additive main effects and multiplicative interaction model (AMMI) to calculate the weighted average of absolute scores and productivity (WAASP), and the GGE biplot graphical analysis. The productive performance of the common bean lines and cultivars is affected by genotype x environment interaction. The methodologies adopted allow the selection of cultivars for cropping, and of cultivars and lines for use as parents in order to obtain segregating populations for selection in a family farming system.
Dietary supplementation with glutamine or glutamic acid for weanling piglets
Authors: Amorim Alessandro Borges , Saleh Mayra Anton Dib , Miassi Gabriela de Mello , Berto Dirlei Antonio
Published: March 2018

Abstract: The objective of this work was to evaluate the effects of dietary glutamine and glutamic acid supplementation on carbon turnover (δ13C) in the muscles of piglets, on animal performance, and on feed economic feasibility. The diets consisted of: control (C), 1% glutamine (G), and 1% glutamic acid (GA). In experiment I, 111 piglets were used to assess carbon turnover in the Masseter, Psoas major, and Abdominal internal oblique muscles in terms of their isotopic composition and 13C substitution over time. In experiment II, 72 piglets were assigned randomly to blocks (eight replicates per treatment and three animals per experimental unit), in order to evaluate animal performance and feed economic feasibility. The GA diet promoted the best 13C acceleration in the studied muscles. No diet effects were observed on performance variables. The G and GA diets presented higher costs than the C diet. Although supplementation with 1% glutamine or glutamic acid accelerates carbon turnover in the studied muscles, which suggests a faster recovery during post-weaning and proves the anabolic effect of these additives, its use is not economically viable for weanling piglets.
Impact of the factors of animal production and welfare on robotic milking frequency
Authors: Córdova Helder de Arruda , Alessio Dileta Regina Moro , Cardozo Leonardo Leite , Thaler Neto André
Published: March 2018

Abstract: The objective of this work was to evaluate the impact of production factors on milking frequency and the latter’s effect on animal welfare in robotic milking. The experiment was performed with Holstein Friesian cows housed in free-stall barns. To assess the impact of production factors, body condition score, milk yield, and concentrate intake were determined. To determine the effects of the milking frequency on welfare, the locomotion and teat-end scores and serum cortisol level were evaluated. Three experimental groups were formed according to the daily average milking frequency: 1.0 to 1.9, 2.1 to 2.9, and above 3.0 milkings per day. The decrease in milking frequency during lactation was related to the reduction in concentrate intake and milk yield. The increase in milking frequency was related to the reduction in the milk flow and the increase in milking duration. Milking frequency was affected by concentrate intake, locomotion problems, milk yield, and lactation stage. The cortisol level and teat-end conditions were not affected by milking frequency. Milking frequency impacts milk flow, duration of milking, and milk composition; however, there is no effect on the indicators of animal welfare.

Abstract: The objective of this work was to evaluate the effects of nutritional plans and breed composition on nutrient intake and digestibility, nitrogen balance, and performance of dairy heifers in tropical conditions. Thirty-six heifers - 12 Holstein, 12 Gyr, and 12 Gyrolando F1 (½ Holstein × ½ Gyr) - were housed in a tie-stall system and randomly distributed, adopting a completely randomized design in a 3×3 factorial arrangement (nutritional plans and breed composition). The diets were formulated to enable weight gains of 200, 400, and 800 g per day, corresponding to the nutritional plans 11, 14, and 19 g kg-1 body weight (BW), respectively. The intake of dry matter, fibrous fractions (g kg-1 BW-0.75), and metabolizable energy (kcal-1 BW-0.75) in the 11-g kg-1 plan were greater for Gyr heifers than for Gyrolando and Holstein heifers. Ether extract digestibility was 13.85% higher for Gyr heifers compared with Gyrolando F1 in the 19-g kg-1 plan. The increase in the nutritional plans shows a quadratic response to nutrient intake and a linear response to average daily gain, but does not affect the digestibility coefficients. Gyr and Gyrolando F1 heifers present similar nutritional efficiency to that of Holstein heifers.
Forças e fraquezas do curso de Gestão Ambiental da Universidade de Brasília
Authors: Almeida Alexandre Nascimento de
Published: March 2018

Resumo Com a aplicação dos recursos do Programa de Apoio a Planos de Reestruturação e Expansão das Universidades Federais (REUNI), a Universidade de Brasília (UnB) ampliou e democratizou seu número de vagas, priorizando a criação de cursos noturnos em regiões periféricas de Brasília. Nesse contexto, criou-se o curso de Gestão Ambiental (GAM) na Faculdade UnB de Planaltina (FUP), em 2008. Em sua primeira avaliação pelo Ministério da Educação (MEC), o curso de GAM da UnB alcançou nota 4, aproximando-se da nota máxima, que é 5. Resultados de pesquisa, porém, revelaram uma alta taxa de evasão e uma baixa empregabilidade do curso, levantando dúvidas sobre sua qualidade e a efetividade da avaliação do MEC. Assim, o objetivo deste estudo foi avaliar a qualidade do curso de GAM da UnB, identificando seus pontos fortes e fracos por meio da percepção de seus egressos. Para tanto, analisaram-se 43 questionários respondidos por egressos do curso por meio da análise de cluster. O estudo revelou que os pontos fortes estiveram relacionados à alta qualidade dos professores, dos servidores e da infraestrutura geral da UnB. Os pontos fracos referem-se a dificuldades inerentes ao fato de o curso ser novo e ainda não reconhecido por um conselho de classe. Questões relacionadas à grade curricular do curso, à qualidade dos laboratórios e da biblioteca, bem como à inclusão dos alunos em projetos de iniciação cientifica, de extensão e em estágios na área de formação se encontraram com qualidade intermediária.
Formação superior rizomática: flexibilidade curricular proposta pela UFABC
Authors: Xavier Allan Moreira , Steil Leonardo José
Published: March 2018

Resumo Ainda que o currículo do bacharelado em ciência e tecnologia (BC&T) da Universidade Federal do ABC (UFABC) apresente uma proposta flexível de formação superior, tal flexibilidade passa, quando de sua execução, por um conjunto de fatores limitadores cujo estabelecimento reaproximam a proposta de um currículo tradicional. Compreender como funcionam os agenciamentos nos quais está circunscrito o curso a partir da identificação de aspectos que o aproximam de um currículo rizomático, assim como das linhas de fuga molarizantes desse projeto formativo, resume o principal objetivo deste artigo. Para tanto, realizou-se um levantamento arqueológico dos discursos a partir de entrevistas semiestruturadas acerca da execução do projeto original e documentos oficiais, incluindo as revisões dos projetos pedagógicos do BC&T da UFABC, e normativas que regulam a execução do curso na universidade. A concomitância das trajetórias formativas entre os cursos de formação interdisciplinar e cursos de formação específica, a carga horária elevada em unidades curriculares de escolha dos alunos e a ausência de pré-requisitos permitiriam ao aluno singularizar sua formação, escapando à unidade curricular pretendida nas tradicionais grades curriculares. Tais possibilidades de compreensão rizomática desse currículo esbarram nas formações tradicionais dos docentes e nas opções de gestão tradicional do currículo, que empurram o projeto no sentido de uma formação tradicional e positivista.
The impact of a fuel levy on economic growth in South Africa
Authors: Ncanywa Thobeka , Mgwangqa Nosipho
Published: March 2018

Government expenditure is one of the factors that could influence economic growth and it depends on borrowing or on the amount of tax revenue. A fuel levy, as an excise tax charged on petroleum products such as petrol, diesel and biodiesel, can be an important source of revenue for the government. It can, however, be a burden on fuel consumers. The present study, as an effort to address this controversy, used the vector autoregressive approach to examine the impact of fuel levies on economic growth in South Africa. The results showed a long-run unidirectional negative relationship between economic growth and fuel levy. The conclusion was that the economy needs to grow at a higher rate so as to boost tax revenues and public expenditure. Strong revenue collection, therefore, depends on highly increasing economic growth and efficient tax administration. The implication of a growth-oriented tax system is to minimise distortions created by the tax system and create incentives for drivers of economic growth.

Analysis of the influence of lubrication conditions on tool wear used in hot die forging processes
Authors: Hawryluk M. , Gronostajski Z. , Ziemba J. , Dworzak Ł. , Jabłoński P. , Rychlik M.
Published: March 2018

The study discusses the subject of lubrication in the processes of hot die forging with the consideration of the durability of forging
tools and instrumentation. It presents a literature research as well as the authors’ own investigations of the effect of the use of
cooling and lubrication agents, the amount of the dosage as well as the direction of its application, and also the factors influencing
the tribological conditions. The lubrication devices and systems currently applied in the industry have been analyzed as well. On
this basis, making use of their knowledge and experience, the authors have developed and constructed a lubricating device. The
elaborated system, implemented into the industrial process, makes it possible to select and ensure the optimal tribological conditions of the process by way of controlling the amount and frequency of the applied lubricant dosage. It can constitute an alternative
for the manual method of lubricant application, which is dependent on the human factor, or the fully automated, yet expensive,
lubrication systems. The obtained test results point to potential possibilities of a permanent introduction of the constructed device
also into other forging processes, through its integration with a manipulator. The proposed solution ensures more stability and
higher repeatability of the lubrication conditions as well as increases the efficiency of the production process, thus significantly
reducing the unit costs of the production of forgings
Time-dependent reliability of spur gear system based on gradually wear process
Authors: Zhu L. , Zhang Y. , Zhang R. , Zhang P.
Published: March 2018

To study dynamic evolution law of mechanical reliability caused by wear, gear transmission system is taken as a research object.
Considering the effect of clearance caused by wear on gear teeth load in double meshing area, the formula of dynamic distribution load which is undertaken by two adjacent teeth is deduced. And the distributed pressure and meshing speed, which should
be taken into account while calculating gear wear, are obtained based on the Winkler surface model and principle of tooth mesh.
Based on the Archard’s wear model, numerical simulation model for wear in spur gear is deduced, and the wear depth of each
meshing points on teeth outline with different wear cycles are obtained. The calculation wear model is replaced with a surrogate
model with Neural Network and Kriging method to overcome time-consuming defect. Random process model is integrated with the
surrogate model, and dynamic reliability for nonlinear stochastic structure with unknown distribution characteristic is obtained
with Neural Network-based Edgeworth series technique and four moment methods, which is compared with Kriging-based Monte
Carlo simulation method. The computational efficiency and accuracy are also demonstrated.
Evaluation of engine oil foaming tendency under urban driving conditions
Authors: Wolak A. , Zając G. , Kumbár W.
Published: March 2018

The purpose of the article was to analyze the foaming tendency of engine oils used under excessive operating conditions. To
achieve this end, foaming characteristics were determined for 23 oil samples in three measurement sequences. Foaming tendency
was measured using the ASTM D 892 standard method, which consists in assessing foaming tendency of the liquid and foam stability. The cars used in the tests were uniform in terms of brand, type and operating conditions. The relationship between the mileage
of the cars tested and the volume as well as stability of foam in used engine oils were presented using scatter plots with regression
lines, correlation coefficient and 95% confidence interval. Based on the obtained results it was found that foaming tendency for
new oils is characterized by high variability. The strongest foaming tendency at 24°C and 93°C (Sequence I and II) was observed
for two out of five oil groups. Statistically significant differences were found between mileage and foaming tendency/foam stability
for individual oils tested.
A comprehensive and practical reliability allocation method considering failure effects and reliability costs
Authors: Yu H. , Zhang G. , Ran Y. , Li M. , Wang Y.
Published: March 2018

In view of the drawbacks in existing allocation methods which are incomplete considerations and poor practicality, a comprehensive fuzzy allocation method considering failure effects and reliability costs is proposed. Fuzzy linguistics and triangular fuzzy
numbers are used to evaluate the uncertainty and subjective factors in allocation process. The traditional risk priority numbers
(RPNs) are modified to overcome the shortages which are the same factor weights and equal difference of failure effects in original
methods. State of the arts, components intricacy and working conditions are used to construct the reliability costs model, which
solves the difficulties of costs statistics and avoids the sophisticated calculations which exist in current allocation methods. The

Outline of a method for estimating the durability of components or device assemblies while maintaining the required reliability level
Authors: Zieja M. , Ważny M. , Stępień S.
Published: March 2018

The paper includes a probabilistic method for evaluating the durability of components and device assemblies which
operate under the impact of destructive processes. As a result of these processes, wear that causes deterioration of their
cooperation conditions occurs. It is assumed that a component operates reliably when the wear does not exceed the acceptable (limit) values. In mathematical terms, this method is based on a differential equation, after the transformation
of which, it is possible to obtain the Fokker-Planck type partial differential equation. The specific solution of this equation allows for obtaining the density function of the probability wear in the normal distribution form. The paper presents
two methods for determining the durability. The first one involves the application of the wear density function, and the
second one consists in determining the probability density function of the time of reaching the acceptable state, and its
use in order to determine the component or assembly durability. The paper presents a numerical example on the aircraft
technology operation process
Sensors in Proactive Maintenance – A case of LTCC pressure sensors
Authors: Santo Zarnik M. , Novak F. , Papa G.
Published: March 2018

Sensors are a vital component part of any process-controlled system. Even though designed to properly operate at required conditions within the whole lifetime, all sensors exhibit some level of drift with time. When selecting the sensors for implementation in
a system proactive maintenance their ageing in specific operating conditions should be considered as an important issue. Here
we focus on thick-film piezoresistive sensors based on low temperature cofired ceramic (LTCC) and discuss their ageing in different regimes of operations. Frequent overloading and particularly with limit overpressures can result in observable drifts and
unacceptable scattering from the calibrated characteristics. For the sensors operating in the water the overloads are even more
critical. Moreover, under the regime with frequent overloads, some non-critical, intrinsic defects in the sensing structure, which
normally do not affect the characteristics and are non-detectable by the output tests in serial production may develop into critical
defects that shorten the sensor lifetime
Reliability of interdependent networks with cascading failures
Authors: Peng R.
Published: March 2018

The reliability of network systems of various structures has been studied by many researchers. However, most of the
works just consider the reliability of a single network system. In practice, different networks may be interdependent such
that the failure in one network may result in the failure in another network. The cascading failures have been shown to be
catastrophic by some researchers. However, the quantitative evaluation for the reliability of interdependent networks has
not been proposed. In this paper, a multi-valued decision diagram based approach is presented to evaluate the reliability
of interdependent networks. Illustrative examples are proposed to demonstrate the application of the framework.

Authors: Młynarski S. , Pilch R. , Smolnik M. , Szybka J.
Published: March 2018

Apart from reliability evaluation, the methodology of network systems reliability assessment presented in the article enables the
design of modernisation of such systems targeted mainly at ensuring their required reliability. In practice the methodology can be
applied for various network systems, e.g. computer, power, gas, water distribution, telecommunications and transport networks. A
reliability analysis of a transport network in urban public transport is presented. Calculations were performed for selected criteria
of network availability which actually conditions the quality of transport services provided. The basic calculation tool used was
the factoring algorithm that enabled the assessment of the impact of individual connections failure (in particular those caused by
physical factors) on the reliability of the whole network. The feasibility of modernisation of the network analysed is discussed and
the results are presented in diagrams.

The aim of this paper is to analyse the functioning of the repair brigades in the process of failure removal in the water distribution
subsystem using the mass service system (MSS). An example is presented using queuing model which takes into account notifications with various scheduling algorithms of failures occurring to the system. The functioning analysis of mass service system can
be used in the optimization of the repair teams’ actions and in the management of water supply companies.
Operational quality measures of vehicles applied for the transport services evaluation using artificial neural networks
Authors: Świderski A. , Jóźwiak A. , Jachimowski R.
Published: March 2018

Operational vehicle quality measures are an important element used to evaluate the performance of transport services. In practice,
there are many methods involved in the operational evaluation of vehicles. They are characterized in this article. Artificial Intelligence methods, especially artificial neural networks, can also be successfully used for this purpose, and especially when deciding
on quality assessment processes for machines, including motor vehicles. The use of methods to support decision-making based
on facts is extremely important for the credibility and objectivity of the evaluation. These methods can also be used in relation to
the use of vehicles in the assessment of transport services. The article presents the method of using artificial neural networks for
the operational evaluation of vehicles used in freight transport services. The basis for the verification of the method was an experimental research carried out at a company making dairy products, cooperating with transport companies, supplying products
for the production process. The results obtained from the operation of vehicles from the studied companies have confirmed, at the
probability level of 99%, high efficiency of the proposed method in evaluating transport services using operational vehicle quality
measures.
Optimisation of Non-Periodic Inspection and Maintenance for Multicomponent Systems
Authors: Babishin V. , Hajipour Y. , Taghipour S.
Published: March 2018

A k-out-of-n:G system and a system with components subject to soft and hard failures are both inspected non-periodically. For
the k-out-of-n system, components fail “silently” (i.e. are hidden), and the entire system fails when (n-k+1)st component fails. For
the system with hard-type and soft-type components, hard failures cause system failure, while soft failures are hidden and do not
cause immediate failure of the system, but still reduce its reliability. Every system failure allows for an opportunistic inspection
of hidden soft-type components in addition to the scheduled inspections. The available maintenance types are replacement and
minimal repair. For hard-type components, the maintenance decision is determined by the optimal age before replacement. For the
soft-type components with hidden failures, we do not know their age, and so decide on the appropriate type of maintenance using
the optimal number of minimal repairs before replacement. The hidden nature of soft-type component failures precludes the use of
a tractable analytic expression, so we use simulation and genetic algorithm (GA) to jointly optimise the non-periodic policies on
maintenance and inspection and to ensure these incur minimal expected total cost over a finite planning horizon. Due to increasing computational complexity associated with the number of inspections and maintenance policies to be evaluated, the genetic
algorithm presents a promising method of optimisation for complex multicomponent systems with multiple decision parameters.

Authors: Mohammed Chenar , Aziz Amal , Thanoon Shima
Published: March 2018

Objective: Punica granatum is a herbal product used in the field of dentistry which has many potential effects including  bactericidal, antifungal, antiviral, and immune modulation. This study aimed to evaluate the effect of prepared Punica  granatum as an antiplaque and anti-inflammatory agent in the treatment of gingival inflammation. 

Methods: Sixty patients were enrolled in this study. Fourty five patients with moderate gingivitis were divided randomly into 3 groups; chlorhexidine group included 15 patients received once-daily dose of chlorhexidine mouthwash for 1 day, Punica I group included 15 patients received once-daily dose of Punica mouthwash for 1 day, and Punica II group included 15 patients received once-daily dose of Punica mouthwash for 2 consecutive days. Plaque index, gingival index, and bleeding on probing were assessed before rinsing and after 3 and 7 days of rinsing, also saliva were collected before rinsing and after 1 hour, 2 hrs, 1 and three days of rinsing to estimate the level of interleukine-1β. The rest 15 subjects were with clinically healthy gingiva. 

Results: Punica II group resulted in significant reduction of plaque index, gingival index, and bleeding on probing after 3 and 7 days of rinsing (p≤0.05) but with non-significant differences with chlorhexidine group (p>0.05). It had significant effect in reduction of interleukine-1β which begin after one day of rinsing and continued into three days (p≤0.05).

Conclusions: Punica like chlorhexidine has a positive effect on reduction of plaque accumulation and improvement of gingival inflammation so can be used as an anti-plaque and anti-inflammatory agent in the treatment of gingival inflammation.
THE NUMERICAL STUDY OF HEAT TRANSFER ENHANCEMENT USING AL2O3-WATER NANOFLUID IN CORRUGATED DUCT APPLICATION
Authors: Tokgoz Nehir
Published: March 2018

Heat transfer enhancement
in channel flow is investigated in the present study by using corrugated duct
in lieu of smooth duct. In this regard, periodic different cavities are applied
on the duct walls using the same aspect ratios. The values of the Reynolds
numbers are in the range of 10,000 ≤ Re ≤ 20,000. The effects of the
alumina-water nanofluid flow on the corrugated ducts are alternatively
investigated by using the constant nanoparticle size for further improvement of
the thermal characteristics. Computations are performed by means of finite
volume approach on three different corrugated shapes. The effects of various
parameters on the heat and fluid flow are also studied. The obtained results
have revealed that the application of corrugated duct increases the rate of
turbulent intensity on the central axis of the duct. In addition, it is found
that the rate of heat transfer changes as a result of corrugated shape and
Reynolds number. Furthermore, it is demonstrated that the application of the
alumina-water flow in such ducts enhances the rate of the heat transfer and
thermal performance when compared with the water flow. It is hoped that the
obtained results will arouse interest towards thermal design.
