RICE HUSK ASH AS A NANO-FILLER TO SYNTHESIZE THERMOSETTING POLYMER NANOCOMPOSITES AND EVALUATION OF ITS TRIBOLOGICAL BEHAVIOR
Authors: Burhan Salsabeel , Abed Meethaq , Moslih A. Salih Moslih A. Salih
Published: February 2019

This paper deals with synthesizing of nanocomposites of unsaturated polyester (UP) filled with nano silica and investigation the effect of silica content on the tribological behavior of UP and nanocomposites . Silica nanoparticles were prepared by burning rice husk ash (RHA) as an agricultural waste material. Three different percentages as 2%, 6% and 10% of nano silica were added to the unsaturated polyester and dispersed by using ultrasonic waves method. As a result of agglomeration and sedimentation of nano RHA particles, dispersing by ultrasonic waves was very effective to terminate these challenges. X-Rays diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM) technics were used for characterization of materials. RHA-UP nanocomposites were tested for their tribo-performance by pin-on-disc machine. XRD demonstrated that white rice husk ash consists of amorphous silica. SEM demonstrated that silica particles were distributed uniformly and well embedded within the polyester matrix. Results showed an improvement in wear resistance with relatively stable friction coefficient with the addition of 10% nano silica. Adding 2 wt% nano RHA negatively affected the wear resistance of RHA-UP nanocomposite .The best tribological performance of 10% RHA-UP nanocomposites achieved at load 10N. Incorporation of RHA with unsaturated polyester has advantages of reducing pollution, making the pollutant RHA as a valuable material to produce low cost and lightweight products with modified properties. Silica enriched RHA could prove to be cheaper anti-wear additives for producing high performance unsaturated polyester composites such as brake pads.

Authors: Al-Maliky Firas
Published: February 2019

In this paper, two finite element models were performed. The fiber and matrix represented as two different materials in the first plate, while the second showed as a composite plate. The boundary conditions included clamped the plates on four ends and the dimensions of the composite plates were changed in this study. The finite element was performed and ANSYS 16.1 was employed in modeling. By comparing the results between the frequency ratio and mode numbers for different plate thickness, the results showed that natural frequencies calculated by these two model thickness of the (length/width) ratio will be more uniform and the error will be small. The numerical equations that performed from this study used to investigate the natural frequencies for longitudinal clamped composite plate.

O presente estudo descreve e analisa qualitativamente o caso do “Projeto PIBID na Copa do Mundo” que foi desenvolvido em um colégio público localizado na cidade de Ponta Grossa – PR. Esta atividade foi organizada pelos pibidianos[1] de Educação Física, contou com a participação de aproximadamente 400 alunos do ensino fundamental e médio e foi desenvolvido durante dois meses. O principal objetivo foi proporcionar aos alunos reflexões sobre os legados tangíveis e intangíveis de uma copa do mundo. Após o término das atividades, textos escritos pelos alunos foram analisados, os quais eles deveriam colocar seus posicionamentos a respeito da realização da Copa do Mundo 2014 no Brasil. Utilizou-se como suporte metodológico o Discurso do Sujeito Coletivo (LEFÈVRE et. al., 2000). Verificou-se que a grande maioria dos alunos se apresentam contrários a realização do mundial devido aos excessos de investimentos públicos, os quais não são repassados para a educação e saúde. Conclui-se que cabe ao professor provocar estas reflexões e assim contribuir para a formação de um aluno com pensamento crítico e autônomo. [1]Acadêmicos de graduação integrantes do Programa Institucional de Bolsa de Iniciação à Docência (PIBID).

Por uma história das direitas
Authors: Ferreira Fabrício
Published: February 2019

Alguns estudos indicaram o surgimento de “novas direitas” junto às redemocratizações latino-americanas da década de 1980. Ademais, a atual conjuntura de crise permitiu que as noções de direita e esquerda retomassem o debate público. Assim, por meio de uma revisão bibliográfica, busco identificar interpretações sobre esta temática e avaliar a operacionalidade analítica do conceito de direita. Argumento que as direitas são plurais ao nível ideológico e de atuação. Por fim, defendo que o estudo sobre as direitas é fundamental na explicação dos processos políticos observados no Brasil recente (pós-1985), especialmente no que tange ao combate às desigualdades socioeconômicas e a questões que atritam com valores cristãos conservadores, como o aborto e a diversidade de gênero.

"O que me guia é a memória. E só": O futebol, a paixão pelo Bahia e a catimba nas memórias de Osório Vilas-Boas
Authors: Filho José Eliomar dos Santos
Published: February 2019

No livro ‘Futebol: Paixão e Catimba’, Osório Vilas-Boas expôs seu ponto de vista sobre a forma (repleta de artimanhas para ele, desleal e corrupta para os seus adversários) como fez o Esporte Clube Bahia se tornar o mais popular time do Estado passando a acumular títulos ao longo do período em que esteve sob sua direção. A sua narrativa é classificada como memorialista pois, de maneira livre e parcial, o Autor transforma em palavras o seu olhar sobre o vivido no futebol baiano durante cerca de cinquenta anos. A História critica essa forma de produção documental do passado devido ao pouco cuidado com regras, rituais, métodos que são uma marca registrada da operação historiográfica. O artigo objetiva estabelecer esse confronto de análises entre a obra memorialista de Osório Vilas-Boas e a visão de pensadores como Michel de Certeau e Pierre Nora sobre o valor das memórias para a ciência histórica.

The Determinants of the Effectiveness of Internal Audits with Management Support as the Moderating Variable
Authors: poltak hendra
Published: February 2019

Weak financial accountability reflects the lack of effectiveness of internal audits. The purpose of this research was to test and provide the evidence of the determinants of the effectiveness of internal audits at the Ministry of Marine Affairs and Fisheries (KKP). The samples of this research were 31 internal auditors and 31 KKP employees. This research was explanatory research. To test the hypotheses, the data of the research questionnaire data were analysed using Partial Least Squares (PLS) analysis tool. The results show that the relationship between internal auditors and external auditors, organizational independence, and auditee perceptions positively influences the effectiveness of internal audits. However, audit professionalism does not have a positive effect towards the effectiveness of internal audits and the management support cannot be a moderating variable. This finding can open the horizons of interested parties, especially KKP leaders, to consider policies that can improve the effectiveness of internal audits to improve organizational goals and performance.

Tulisan adalah matahari kehidupan. Dunia tanpa tulisan, ia gelap. Orang-orang yang memiliki kepandaian menulis, ia tak ubahnya bagai suluh di tengah kehidupan kita. Kecakapan menulis, tidak lahir begitu saja. Banyak orang yang memiliki pengetahuan, tapi ia gagap dalam kecerdasan menulis. Kepandaian menulis karena kegemaran membaca, mendengar, melihat dan merasakan serta terus menerus melatih diri untuk menulis. Orang yang memiliki pengetahuan dan memiliki daya intelektual yang lebih , bila ia enggan berlatih menulis, maka penyebaran pengetahuan yang ia dapatkan akan terbatas dibanding orang-orang yang memiliki pengetahuan tapi memiliki kecakapan menulis . Pikiran dan tulisan adalah mahkota di tengah kehidupan dunia intelektual kita. Satu persepsi kita semua, khususnya di lingkungan Fakultas Ekonomi Universitas Negeri Padang, bahwa kita sangat mendukung kegiatan literasi mahasiswa. Literasi, bukan hanya sebatas membaca dan menulis, lebih dari itu, literasi adalah implementasi dari pikiran dan perbuatan kreatif. Namun demikian, semangat membaca dan menulis adalah hulu dari sebuah pikiran untuk melahirkan dan menciptakan pikiran - pikiran kreatif.
Politics, Personality, and Impulsivity Can Color People’s Perceptions of—and Responses to—Hurricane Threats of Varying Severity
Authors: Losee Joy Ellen , Smith Colin , Webster Gregory D.
Published: February 2019

Theory and research suggest that objective features of a threatening situation and individual differences influence threat responses. We examine three ways individual traits may relate to a threat response: (1) directly and independent of objective threat features, (2) indirectly through relationships with threat perception, or (3) as moderators of the relationship between objective threat features and responses. Using Integrative Data Analysis (IDA; Curran & Hussong, 2009), we aggregated data across three studies examining hurricane preparation intentions. Analysis supported two of the potential pathways. Supporting the first path, both openness and extraversion had direct, positive relationships with preparation likelihood. Supporting the second path, agreeableness, conscientiousness, and social conservatism positively related to preparation likelihood through a positive relationship with threat perception, whereas impulsivity and sensation-seeking negatively related to preparation likelihood through a negative relationship with threat perception. This work shows the pivotal role individual differences play regarding responses to uncertain threats. **Differences between preprint versions reflect changes made to address reviewer comments from a prior submission.

Background. Continued use of practices not supported by empirical evidence is an ongoing challenge in the field of autism spectrum disorder (ASD). Knowledge and individual attitudes to evidence-based practice, as well as accuracy of categorization of practices on their evidence base, have been linked to practice selection in allied health professionals. This study aimed to extend this research to early intervention staff, and investigated perceived evidence base of practices, and links to intended future use, along with individual attitudes and sources of information accessed.Method. Participants included 86 early intervention staff who completed an online survey. They rated the evidence base of six ASD intervention practices (three unsupported by research, three empirically supported), along with current and intended future use of these, as well as attitudes to research and to evidence-based practice. Results. At a group level, participants reported using, and intending to use in future, the empirically supported practices more than unsupported practices, and generally accurately reported a higher evidence base for the empirically supported practices. However, a number of individual participants showed inaccuracy in ratings varying by practice. Perceived evidence was linked to greater intention to use practices in the future, while few links to individual attitudes were found. Conclusions. Our findings point to the influence of perceived evidence on intended use of practices. Perceived evidence may be impacted by lack of awareness and/or misinformation regarding the evidence base of practices. The need for accurate information about both empirically supported and unsupported practices, as well as strategies to seek and evaluate information are highlighted. Limitations of the self-report methodology, and future research directions including broader clinical decision-making processes are overviewed.

Import Inflows of Bangladesh: The Gravity Model Approach
Authors: Alam Md. Mahmudul , Uddin Gazi Salah , Taufique Khan Md. Raziuddin
Published: February 2019

Bangladesh suffers from a chronic deficit in her trade balance. The paper is an attempt to explore the imports of Bangladesh which is one of the most significant factors responsible for unfavorable trade balance of the country. The aim of the study is to intend some initiatives for an attempt to ultimately reshaping the trade balance of Bangladesh with her foreign trade partners. The paper examines the existence of the gravity theory for the imports of Bangladesh with its eight major trading partner countries- India, China, Singapore, Japan, Hong Kong, South Korea, USA and Malaysia. The data set consists of yearly data from 1985 to 2003 in a panel approach. The paper comes across with the findings that the gravity theory is consistent with the imports of Bangladesh. That is, the geographical distance of Bangladesh with its partner countries has significant impacts on its imports. But in near future this may change because of different factors such as profitability, easy trade procedures, product delivery time etc. that influence the imports decision more than does the geographical distance. This paper finds mixed relationship between the GDP and imports of Bangladesh. It also shows that the imports of Bangladesh influence the domestic production very little because Bangladesh mostly imports consumer goods rather than capital goods. Moreover, the population of Bangladesh has significant impacts on imports which in turn implies that Bangladesh is not capable of producing adequate consumer goods to meet the increased demand resulted from high population growth. It also shows that partner countries‟ GDP has significant positive impacts and partner countries‟ population has mixed impact on imports of Bangladesh. This paper concludes that it will be an alarming situation for trade balance of Bangladesh if the imports continue to increase in such a pattern that the rate increases five to eight times more in respect of population increases and at the same time the ratio of capital goods in proportion of total imports decreases.
Geosilhouettes: geographical measures of cluster fit
Authors: Wolf Levi John , Knaap Elijah , Rey Sergio J.
Published: February 2019

Regionalization, under various guises and descriptions, is a longstanding and pervasive interest of urban studies. With an increasingly large number of studies on urban place detection in language, behavior, pricing, and demography, recent critiques of longstanding regional science perspectives on place detection have focused on the arbitrariness and non-geographical nature of measures of best fit. In this paper, we develop new explicitly-geographical measures of cluster fit. These hybrid spatial-social measures, called geosilhouettes, are demonstrated to capture the "core" of geographical clusters in racial data on census blocks in Brooklyn neighborhoods. These new geosilhouettes are also useful in a variety of boundary analysis and outlier detection uses. These new measures are defined, demonstrated, and new directions are suggested.
Criticism and Psychology: The Understanding with a Postmodern Psychology
Authors: Millán Juan David , Cudina Jean Nikola , Ossa Julio César
Published: February 2019

Frequently, “Critical psychologies” question the ideological and political framework that develops and legitimizes certain mainstream psychology. Nevertheless, it is still a field of knowledge which has not been fully differentiated from its crisis –mainly- because an exhaustive ontological categorical demand has not been made. From the analysis of Ian Parker’s La Critical Discourse Psychology (CDP) and Critical Psychology, we observed that the causes and consequences of the introduction of Scientific realism as an intermediate stage in the elaboration of what has been called radical meta-psychological project or a general critic of psychology. We reviewed, from the quantitative method Multi-RPYS References, an approximate of 51 papers and 10 books of Ian Parker's work analyzed by the web program RPYS i/o. From the start, CDP and PCL avoided the short form of the critic, which is barely a differentiation from the totality of dominant psychology. Instead, they announced, implicitly, some methodological and theoretical tools which could be useful to prevent its definite adhesion to post-modernism, where "anything goes" is its most manifest condition.

These maps typically depict the area accessible from a point within a certain time or distance threshold. This article details a design alternative to conventional isochrones, which links travel times to network edges. Benefits of this technique include highlighting the network structure of transport networks and comparing travel times for different travel scenarios. This article details methods for producing these maps using free and open-source data and software and provides examples of visualizing different accessibility scenarios in Toronto, Canada.
Patterns of Change in Dynamic Risk Factors over Time in Youth Offenders

Published: February 2019

Risk assessments that include dynamic risk factors are increasingly being utilized within the youth justice system to predict a young person’s likelihood to reoffend, to assist with case management, and to better inform intervention services. However, most studies to date have relied solely on single-wave cross-sectional research designs that essentially treat dynamic risk factors as static. Thus, it is unclear whether and how putative dynamic risk factors change over time, a question that has significant implications for assessment and case management policy and practice. Using a widely used and validated risk assessment and case management instrument (the Youth Level of Service/Case Management Inventory), the purpose of the present study was to examine whether the dynamic risk factors outlined in the Risk-Need-Responsivity (RNR) model do in fact change over time and, if so, to investigate the effect of youth-specific predictors on these changes. Two hundred youth offenders were tracked from their first risk assessment conducted at probation to their transition out of the youth justice system. Results from generalized linear mixed modelling (GLMM) and latent class growth modelling (LCGM) analyses indicated that most dynamic risk domain scores increased over time, but that there was significant individual variation among youth at initial status and in the rate of change. Even when controlling for youth-specific factors, youth who were lower risk at the time of initial assessment increased in risk at a greater rate than higher-risk youth. Results have implications for the RNR framework, for improving the accuracy of risk assessments, and for informing treatment implementation.
The Bystander Effect of Ultraviolet Radiation and Mediators
Authors: Eftekhari Z , Fardid R
Published: February 2019

A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, chromosomal abnormalities, delay and premature mutations and micronuclei production. The most involved genes in creating this phenomenon are cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), the nuclear factor of kappa B (NFkB) and Mitogen-Activated Protein Kinases (MAPKs).Radiation generated reactive oxygen species (ROS) can damage DNA, membranes and protein buildings. Studies have shown that Vitamin C, Hesperidin, and melatonin can reduce the number of ROS and have a protective role.Silver nanoparticles (Ag NPs) are the most abundant nanoparticles produced and when they enter cells, they can create DNA damage. Studies have shown that combined treatment with UVR and silver nanoparticles could form γ-H2AX and 8-hydroxy-2′-deoxyguanosine (8-OHdG) synergistically.This article reviews the direct and the bystander effects of UVR on the nuclear DNA, the effect of radioprotectors and Ag NPs on these effects

Published: February 2019

Detection and quantitative estimation of deep defects in multi-layered structures is an essential task in a range of technological applications, such as maintaining the integrity of structures, enhancing the safety of aging aircraft, and assuring the quality of products. A novel approach to accurately quantify the two-dimensional axisymmetric deep defect size from eddy current nondestructive testing (NDT) signals is presented here. The method uses a finite element forward model to simulate the underlying physical process and an improved ant colony algorithm (IACA) to solve the inverse problem. Experiments are carried out. The performance comparison between the IACA method and the least square method is shown. The comparison results demonstrate the feasibility and validity of the IACA method. Between them, the IACA method gives a better estimation performance than the least square method at present.

The results of the investigation of both mechanical and acoustic emission (AE) behaviors of Mg4Li5Al alloy subjected to compression and tensile tests at room temperature are compared with the test results obtained using the same alloy and loading scheme but at elevated temperatures. The main aim of the paper is to investigate, to determine and to explain the possible influence of factors related with enhanced internal stresses such as: segregation of precipitates along grain boundaries or solute atoms along dislocations (Cottrell atmospheres) or dislocation pile-ups at grain boundaries which create very high stress concentration leading to fracture. The results show that the plastic instabilities are related to the Portevin–Le Châtelier phenomenon (PL effect) and they are correlated with the generation of AE peaks. The fractography of breaking samples was analyzed on the basis of light (optical), TEM and SEM images.

Published: February 2019

This work is devoted to the development of an experimental method for studying the energy balance during cyclic deformation and fracture. The studies were conducted on 304 stainless steel AISE and titanium alloy OT4-0 samples. The investigation of the fatigue crack propagation was carried out on flat samples with different geometries and types of stress concentrators. The heat flux sensor was developed based on the Seebeck effect. This sensor was used for measuring the heat dissipation power in the examined samples during the fatigue tests. The measurements showed that the rate of fatigue crack growth depends on the heat flux at the crack tip.

The mixed mode loading configuration occurs in many civil engineering and mechanical applications. In wood material, the study of this problem is very important due to the orthotropic character and the heterogeneity of the material. In order to study the mixed mode loading in wood material, Moutou Pitti et al [1] have proposed a new specimen called Mixed Mode Crack Growth (MMCG). The main goal of this geometry is to propose a decrease of the energy release rate during the crack growth process. In this case, the fracture parameters can be decoupled into Mode I and Mode II in order to determine the impact of time during creep crack test. The present work proposes to study the crack path stability in MMCG specimen for different sizes and thicknesses. The M? integral, combining real and virtual mechanical displacement fields is used in order to separate numerically mode I and mode II in the mixed mode ratio. The stability is shown for the opening mode (Mode I), the shear mode (Mode II), and the mixed mode of 15°, 30°, 45°, 60°, 75° by computing the energy release rate versus the crack length. Finally, it is shown that the MMCG specimen can be reduced in various shape and used for example in small climate chamber in order to perform creep test at different temperature and moisture content levels.
Multiaxial fatigue crack path prediction using critical plane concept
Authors: Albinmousa Jafar
Published: February 2019

Prediction of fatigue crack orientation can be an essential step for estimating fatigue crack path. Critical plane concept is widely used due to its physical basis that fatigue failure is associated with certain plane(s). However, recent investigations suggest that critical plane concept might need revision. In this paper, fatigue experiments that involve careful measurement of fatigue crack were reviewed. Predictions of fatigue crack orientation using critical plane concept were examined. Projected length and angle were used to characterize fatigue crack. Considering the entire fatigue life, this average representation suggests that it is more reasonable to assume the plane of maximum normal strain as the critical plane even though fundamentally the plane of maximum shear strain is more likely to be the critical one at early initiation stage.
Fatigue characterization of a crankshaft steel: Use and interaction of new models

Published: February 2019

The peculiar geometrical shape and working conditions of crankshafts make fatigue becoming responsible for most of the failure cases in such components. Therefore, improvement of crankshaft performance requires enhancing its fatigue life. In this work, the fatigue behavior of a D38MSV5S steel, used for crankshafts in compact vehicles, is investigated according to two traditional ways of analysis, namely the stress based and the fracture mechanics based approaches, though using advanced design models: On the one side, a probabilistic Weibull regression S-N model is assessed for experimental results obtained from fatigue resonance tests. On the other side, the crack growth rate curve is calculated from crack growth tests, carried out on SENB specimens, using a normalizing procedure. Specific Matlab programs are developed to facilitate the evaluation process. The information gained from both models will contribute to provide a probabilistic interpretation to the Kitagawa-Takahashi diagram.
