Authors: Candellone Alessia , Peiretti Pier Giorgio , Masoero Giorgio , Meineri Giorgia
Published: January 2019

The aim of this study was to find a correlation between in vivo NIR scan patterns, oxidative status, and blood serum metabolites in rabbits fed diets protected or unprotected against oxidation. Rabbits does in groups of eight were fed for 9 weeks with diets containing linseed, rich in polyunsaturated fatty acids (LS), or linseed plus hazelnut skins, with antioxidant function (LS+HS), and palm oil, rich in saturated fatty acids (PO). The animals were examined at days 1, 31, and 63 using a smart SCÏO molecular sensor, a new miniaturized web-based wireless device, applied to the internal ear flap (NIR range 740-1070 nm). The hazelnut peels integrated diet protected the rabbits from the oxidative stress induced by the addition of unprotected polyunsaturated fats. NIR tomoscopy was variously correlated with serum parameters, lysozyme (R2=0.71), ROMs (0.47), cholesterol (0.49), triglycerides (0.40), and a multivariate Index of Oxidative Risk (0.67 [IOR]). The correlations suggested a close connection between the clustering of the diets according to the laboratory variables and the NIRS scan pattern clustering at the ending trial day, as shown by the highly significant odds ratios. Advantageous use of this simple, painless technique was evident in the planning phase, with no difference among the groups at the beginning of the study, but an effect size that evolved differently over time until the end of the study. In a practical validation of the SCÏO model in 92 commercial rabbit does, the average spread of the predicted IOR was 33% in lactating does (2.54±0.05) vs. dry does (1.91±0.07).
Analytical Solutions for the Propagation of UltraShort and UltraSharp Pulses in Dispersive Media
Authors: Granot Er'el
Published: January 2019

Ultrashort pulses are severely distorted even by low dispersive media. While the mathematical analysis of dispersion is well known, the technical literature focuses on pulses, which keep their shape: Gaussian and Airy pulses. However, the cases where the shape of the pulse is unaffected by dispersion is the exception rather than the norm. It is the object of this chapter to present a variety of pulses profiles, which have analytical expressions but can simulate real-physical pulses with greater accuracy. In particular, the dynamics of smooth rectangular pulses, physical Nyquist-Sinc pulses, and slowly rising but sharply decaying ones (and vice-versa) are presented. Besides the usage of this chapter as a handbook of analytical expressions for pulses' propagations in a dispersive medium, there are several new findings. The main ones are: Analytical expressions for the propagation of chirped rectangular pulses, which converge to extremely short pulses; analytical approximation for the propagation of Super-Gaussian pulses; the propagation of Nyquist Sinc Pulse with smooth spectral boundaries and an analytical expression for a physical realization of an attenuation compensating Airy pulse.
Effect of DEM Resolution on Runoff Yield, and Sensitivity of Parameters Contributing to Runoff in a Watershed
Authors: Nazari-Sharabian Mohammad , Karakouzian Moses , Ahmad Sajjad
Published: January 2019

Digital Elevation Models (DEMs) are essential in watershed delineation, but the sensitivity of simulated runoff to DEM resolution is poorly understood. This study investigates the impact of DEM resolution on topological attributes and simulated runoff in the Mahabad Dam watershed, Iran. To delineate the watershed, DEMs with 12.5 m, 30 m, and 90 m resolutions were acquired from the ALOS PALSAR, Space Shuttle Radar Topography Mission (SRTM), and ASTER global DEM data source, respectively. Watershed and streamlines were delineated in ArcGIS, with hydrologic analyses performed using the Soil and Water Assessment Tool (SWAT). Sensitivity analysis on parameters contributing to runoff was done using Sequential Uncertainties Fitting Ver-2 (SUFI-2) Algorithm, in SWAT Calibration and Uncertainty Procedures (SWAT-CUP) software. Results showed the watershed area, reach lengths, and elevations in the watershed varied due to DEM resolutions. Higher amounts of runoff were generated when DEMs with finer resolutions were implemented. The 12.5 m DEM generated 3.48% and 0.42% more runoff compared with 90 m and 30 m DEMs, respectively. SWAT-CUP results showed the sensitivity of parameters contributing to runoff changes under different DEM resolutions. Regardless of DEM resolution, surface properties, available water capacity, and moisture levels in the soil are the most sensitive parameters. As the distribution of slope changes in different DEM resolutions, surface parameters are most affected. The findings indicate to reduce computation time and speed up computation procedures, researchers may use DEMs with coarser resolutions at the expense of minor decreases in accuracy.
A New Location-Based Services Framework for Connected Vehicles Based on the Publish-Subscribe Communication Paradigm
Authors: Sonklin Kachane , Feng Yanming , Jayalath Dhammika , Wang Charles
Published: January 2019

Location-Based Services (LBS) have been widely deployed for the connected vehicle (CV) applications such as vehicle navigation,vehicle tracking and location-based augmented reality. The current LBS deployments have limitations in supporting time-critical CV use cases, including vehicle to vehicle (V2V), vehicle to infrastructure (V2I) and vehicle-to-people (V2P) safety applications. The paper presents the new LBS framework based on the publish-subscribe communication paradigm, to enable device-to-device (D2D) connections through use of selected application protocols in the application layer of the TCP/IP layered protocol model. Two publish-subscribe application protocols, Distributed Data Service (DDS) real-time publish and subscribe (DDS-RTPS) and Message Queue Telemetry Transport (MQTT), are introduced to support the LBS D2D applications. A number of test scenarios with Mosquitto MQTT and OpenDDS under 4G-mobile broadband (MBB) services are designed to assess the transmit/receive round-trip time (RTT) and packet-loss rate (PLR) with settings of a publisher to multiple subscribers, to simulate the connections to multiple vehicles. The transmission frequency is set for 10 Hz and the message sizes vary from 100 to 2000 Bytes. The PLRs are defined as the percentages of the delayed messages beyond a delay limit. Static test results with OpenDDS show that for the RTT delay beyond the limit of 100 ms, the total PLRs range between 5.25% and 8.76% for the message size of 50 to 2000 Bytes. Vehicle testing results with Mosquitto show that PLRs for the RTT delays between 200 ms and 1000 ms are 0.63%, 3.58% and 5.77%, for connections with 1, 4 and 10 vehicles, respectively. The results demonstrate the potential of the D2D LBS framework for medium-demanding CV safety applications such as V2P and V2I use cases, taking advantages of the 4G-MBB services and 5G extreme mobile broadband (eMBB) services and mobile devices generally available with all road users.

This research aims to be forming the right framework to optimize the management of public assets utilization by DJKN (Direktorat Jenderal Kekayaan Negara) using Resourced Based View (RBV). The method used is a case study. The results show that there are many idle assets that haven’t been used, asset that haven’t use optimally for serving (under used), and many assets haven’t been used corresponding with highest and best uses. It means that there are potencial resources and capacities that haven’t maximally used because of many limitations. This condition can cause the losses of opportunity to optimizing the asset utilization either for the job and function of the government or the opportunity loss in getting state revenue from those optimally asset utilization through corporation with the third party. So, public assets management should be done by optimizing resources and capacity which are owned. Here, empowerment of all of resources and capacity that belong to the organization, can be done to support the achievement of the core value which is optimally public assets utilization. That’s why the right framework of the publics asset utilization with RBV approach is hoped to give a solution for the problem that came from management and utilization of capacity and resources that haven’t been run well.

Authors: García Ocaña Jesús Alfredo , López Ocaña Gaspar , Torres Balcázar Carlos Alberto
Published: January 2019

El objetivo del presente estudio fue evaluar la remoción de parámetros de control y contaminantes básicos de aguas residuales domésticas con humedales artificiales de flujo subsuperficial, para lo cual se emplearon dos medios diferentes de soporte: grava de canto redondo y grava de brecha sedimentaria, con vegetación Sagittaria latifolia (cola de golondrina) y con tiempos de retención de 4.8 días y 4.9 días, respectivamente. En concreto, se destinaron tres humedales con vegetación y grava de canto redondo (HACC), tres con vegetación y grava de brecha sedimentaria (HABC), así como tres humedales controles sin vegetación y grava de canto redondo (HACS) y tres sin vegetación y grava de brecha sedimentaria (HABS). Para los medios de soporte se determinaron variables como densidad aparente y real, así como porosidad y conductividad eléctrica (N = 28). Al inicio de la operación de los humedales artificiales, el medio de soporte canto redondo presentó los siguientes valores: densidad aparente de 1390.79 ± 54.36 kg m-3 (media ± DE), densidad real de 2626.01 ± 75.43 kg m-3, porosidad 51.87 ± 3.90 % y conductividad eléctrica (CE) 125.46  ± 11.81 dS m-1. El medio de soporte brecha sedimentaria mostró una densidad aparente de 1415.63 ±43.94 kg m-3 (media ± DE), densidad real de 2678.16 ± 36.67 kg m-3, porosidad 52.86 ± 1.56  % y CE de 94.13 ± 3.58 dS m-1. Al término de la operación, el medio de soporte de canto redondo demostró ser eficiente con tan solo una pérdida de 5 % de porosidad, mientras que la brecha obtuvo una pérdida de 23 % de esta. En cuanto a la calidad del agua, se analizaron 160 muestras compuestas para los cuatro tratamientos de humedales y 40 simples en el tanque de distribución alimentación (N = 40). Después del primer año de operación, se observa que el HACC es el más eficiente, pues la remoción alcanzada fue de 96.85 % para SST, 95.85 % para DBO5, 96.78 % para NT y 96.79 % para PT. El tratamiento HABC, por su parte, consiguió eficiencias de remoción de 95.52 % para SST, 95.02 % para DBO5, 95.45 % para NT y 95.36 % para PT. Por tal motivo, se considera que existe un alto potencial para que estos medios de soporte se puedan implementar en los HA en el sureste de México, con lo cual se reducirían los costos de construcción y mantenimiento, pues los utilizados actualmente no son nativos de la región, presentan erosión y atrición, y no permiten un adecuado crecimiento de la biopelícula y la vegetación, de ahí que tengan bajas eficiencias.

Inovasi Pembelajaran Pendidikan Agama Islam Berbasis Problem Based Learning
Authors: Mailani Ikrima
Published: January 2019

Educators are very important in their efforts to achieve the desired learning goals in the activities of the teaching and learning process. While students act as subjects as well as objects in applying strategies, models and learning methods. Various ways can be done by the teacher/lecturer to be able to convey information to students (knowledge transfer), both in the form of learning related to teaching materials or insightful ones globally. The process of transferring knowledge with the classical/traditional method can no longer be maintained, because students who are expected by the community are intelligent students who are responsive to the development of the times, and not just as spectators and listeners. The breakthrough offered by observers of education is with a new concept, namely the Problem Based Learning (PBL) learning model, this learning model is not just a process of transferring knowledge from teacher to student, but students can do, try and reconstruct their own teaching materials based on problems existing in the educational environment. Changing the old paradigm that states that every problem must be avoided, but changing it into a new paradigm, that a problem must be faced and the solution sought as soon as possible, so also in the process of teaching and learning activities that give birth to effective, creative and innovative learning.

As a medium of communication, a song has a great impact on children’s development. A small number of children song generate children to sing adult songs, however, there are some adult songs which are not suitable the children in relation to lyrics and theme. The incomprehension of the lyrics and meaning existed in the song can be psychologically influential for the child’s development. This study analyzes the role of Walt Disney’s cartoon soundtracks for character education to children. This is a qualitative-descriptive research, taking observation and in-depth interview to 10 informants who have children of 7-11 years old in Yogyakarta, Indonesia. The results stated that the soundtracks How Far I’ll Go and Let It Go bring positive characters in contents that are useful for character education. The character education taken from lyrics of the songs is conveyed and developed by vocabulary enrichment, the discussion in easy-digested language, and storytelling. These require special time. The good changes in children’s good characters happen by time and process. Therefore, character education needs to be continued and developed in different ways.

Os métodos analisados foram: (1) plantio de grama “São Carlos” (Axonopus compressus); (2) serrapilheira, constituída por galhos e folhas de eucalipto E. Grandis e, (3) envelopamento com um solo local com características mais resistentes aos processos erosivos. O experi mento consistiu da montagem de quatro células retangulares, sendo uma para cada método de proteção e uma mantida desprotegida para avaliação da eficiência dos tratamentos. A determinação da quantidade de sedimentos erodidos baseou-se no somatório dos sólidos em suspensão e nos sedimentos armazenados em bolsa de geotêxtil. O estudo da erodibilidade dos solos foi realizado através de ensaios de identificação em laboratório. Os resul tados de campo, quando comparados à célula desprotegida, mostraram que a serrapilheira obteve uma redução da perda de solo de 90%, enquanto a grama e o envelopamento reduziram 80% e 65%, respectivamente.

Avalia-se a capacidade de carga do sistema estaca-solo formado por estacas tubulares de aço de alta resistência estrutural cravadas em uma argila mole apoiada em um solo residual de gnaisse. As duas estacas analisadas neste artigo foram submetidas a elevadas energias durante uma prova de carga dinâmica de energia crescente (DIET). Os resultados da DIET mostraram que o comportamento do sistema estaca-solo estudado foi comandado pelo elemento estrutural de fundação. Estes resultados foram comparados com os resultados de métodos semi-empíricos de previsão da capacidade de carga (Aoki-Velloso, 1975; Décourt Quaresma 1978, 1982) e com os resultados de provas de carga estática (PCE) realizadas posteriormente nas mesmas estacas já sobrecarregadas, e em condições distintas das da DIET. Os valores de capacidade de carga obtidos pela norma brasileira ABNT 6122 foram inferiores aos obtidos pela DIET. A resistência do sistema estaca-solo obtida na PCE atingiu em torno de 70% a 80% da carga de escoamento da estaca.

Cartas de suscetibilidade à erosão podem ser utilizadas como subsídio para o desenvolvimento de instrumentos de gestão ambiental. Os resultados da pesquisa aqui apresentados discutem a qualidade das informações de cartas em diferentes escalas, elaboradas visando a gestão ambiental de rodovias. Para tanto, foi desenvolvida pesquisa em trecho da Rodovia Marechal Rondon SP-300, nos municípios de Anhembi e Botucatu, no estado de São Paulo - Brasil. A investigação, utilizando o método do detalhamento progressivo, partiu da análise de mapas e cartas em escala regional (escala 1: 1 000 000 e 1: 500 000), culminando na ela - bo ração de cartas de suscetibilidade à erosão nas escalas 1: 50 000 e 1: 10 000, além de outros levantamentos específicos. Paralelamente, desenvolveu-se uma análise sobre os Sistemas de Gestão Ambiental – SGA em órgãos rodoviários. Como resultados da pesquisa, foram desenvolvidos os seguintes instrumentos que com põem um SGA: Caracterização de Impacto Ambiental, Auditoria Ambiental, Recuperação de Áreas Degradadas e Monitoramento Ambiental
Evolução da concentração de nitrato nas águas subterrâneas da região norte de Natal, Nordeste do Brasil
Authors: Martins Guttenberg , Castro Vera
Published: January 2019

Na região norte de Natal, um terço do total das águas destinadas ao consumo humano é captado de poços tubulares. Entretanto, a expansão urbana sem infraestrutura sanitária tem produzido um aporte de nitrato, comprometendo sua qualidade. Baseado num conjunto de dados de concentração de nitrato nas águas subterrâneas (dezembro 2003 – julho 2009), o presente trabalho identifica áreas com valores de nitrato superiores ao limite permitido pela legislação ambiental. Os dados foram interpretados com o suporte de cartas de isovalor, obtidas pela metodologia de interpolação por krigagem simples. Os resultados obtidos apontaram áreas com elevada concentração de nitrato situadas geralmente adjacentes às lagoas interdunares, com variações sazonais dos valores das concentrações de nitrato relacionadas com a variação do regime pluviométrico, e sugerem que a intensa exploração das águas subterrâneas por poços tubulares tem amplificado a dispersão do nitrato e que a carga de nitrato pode atingir o estuário do rio Potengi.

Após alguns anos em que o transporte ferroviário teve um declínio acentuado, ultimamente tem vindo a assistir-se, em vários países, à modernização de linhas férreas antigas, nomeadamente procedendo à reabilitação da via-férrea. Vários desses casos referem-se a vias que se pretende que venham a servir essen - cial mente o transporte de mercadorias. Durante a reabilitação das vias férreas existem vantagens técnicas, económicas e ambientais em manter, se possível, os materiais existentes, em particular a camada de balastro ferroviário contaminado com solos finos, sob as novas camadas de reforço. Este trabalho apresenta resultados de estudos realizados com o objetivo de reabilitar uma via-férrea para o transporte de mercadorias, localizada em África. Para além da caracterização realizada in situ, construíram-se trechos experimentais para testar diversas soluções estruturais para reabilitação da plataforma ferroviária e realizaram-se modelações numéricas da via, contemplando essas soluções. Os resultados dos estudos permitiram concluir que é possível levar a cabo o reforço estrutural da plataforma, de forma eficiente, em termos técnicos e económicos.

Published: January 2019

No Brasil, verifica-se que grande parte da rede viária, 79,9% do total das rodovias, é composta por estradas não pavimentadas – “estradas de baixo-custo”. Observa-se que parte do orçamento de gestão da rede rodoviária do país é utilizada na manutenção rotineira dessas estradas após periodos de chuva. Entretanto, estes gastos poderão ser minimizados pela construção de uma superfície de rolamento de baixo custo, resistente tanto às intempéries da região quanto aos esforços desenvolvidos pelo tráfego. A finalidade deste trabalho é divulgar o método de dimensionamento desenvolvido pelo Programa de Assistência ao Transporte Local de Dakota do Sul, nos EUA, para determinação da espessura do revestimento primário das estradas de terra, direcionando-o ao território Brasileiro. Com base no método, o projetista, para além de obter uma significativa redução dos custos da construção destas infraestruturas, pode também estimar com maior exa ti dão as ações de reparação da seção construída, durante o ciclo de vida da estrada, priorizando a durabilidade da mesma e reduzindo os custos de manutenção.

O Acompanhamento Técnico de Obra (ATO) especialmente na construção de túnel em NATM é fundamental para a garantia de qualidade, segurança e prazo/custo. Além de muita experiência, o profissional responsável pelo ATO deve relacionar, interpretar e disponibilizar as informações da instrumentação e do cotidiano para os envolvidos na obra. Este trabalho descreve a implementação e a aplicação de uma ferramenta online de suporte à tomada de decisão, desenvolvida para auxiliar o trabalho do ATO na execução do Túnel Dois Leões, na cidade de Salvador, Brasil. Além disto, o trabalho também apresenta o uso de geoestatística para a análise da variação espacial dos dados de instrumentação da obra.
Ativismo poético
Authors: Nogueira Pedro Caetano Eboli
Published: January 2019

O presente artigo se destina a compreender os nexos entre arte e política no âmbito das ações de ativismo urbano perpetradas por coletivos e expostas como trabalhos de arte. Partimos do pressuposto de que haveria uma natureza poética nestas ações, que possibilitaria sua fácil inserção no meio da arte. Para tal, observamos algumas ações dos coletivos Frente Três de Fevereiro e Política do Impossível, expostos em diversas mostras de arte. Caracterizamos a natureza poética de seus trabalhos através dos subsídios teóricos oferecidos por Jacques Rancière e Roland Barthes, relacionando-a a uma recusa do devir comunicativo da linguagem. Esta natureza possibilitaria sua transposição para os meios da arte, no âmbito daquilo que Jacques Rancière compreende por Regime Estético.

O artigo desenvolve uma crítica à 33ª Bienal de São Paulo, sob curadoria de Gabriel Pérez-Barreiro. Analisando a proposta curatorial de convidar artistas para organizarem núcleos curatoriais, sem que o curador abra mão de suas próprias escolhas individuais, o autor problematiza o que aponta ser um projeto fraturado e problemático. É de interesse do autor também refletir sobre o modelo Bienal na contemporaneidade: seus dilemas, debilidades, prospecções, assim como possíveis agenciamentos com o capital.
A pregnância da forma
Authors: Gontijo Juliana Coelho
Published: January 2019

O artigo desenvolve uma reflexão sobre a curadoria da 33ª Bienal de São Paulo a partir de duas exposições individuais ali apresentadas: a do artista guatemalteco Aníbal López e a do paraguaio Feliciano Centurión. O objetivo da autora é pensar como são estabelecidas as relações de afeto e proximidade entre obras e espectadores numa bienal pautada por um discurso sobre a dimensão sensível da forma. Na dimensão teórica proposta por Mário Pedrosa, um dos referentes do partido curatorial dessa bienal, a forma pode veicular e conduzir afetos, criar redes ou desestabilizar as dimensões da realidade experimentada para abrir novos mundos. Este artigo pensa, portanto, a partir da vivência pessoal do espaço expositivo, as afinidades afetivas que a curadoria traduz no Pavilhão do Ibirapuera.

Stress Concentration Factors (SCFs) in Circular Hollow Section CHS-to-H-shaped Section Welded T-Joints under Axial Compression
Authors: Hamdan Abderlahman Ismaeel
Published: January 2019

The aim of this paper is to investigate the effects of non-dimensional geometric parameters on stress concentration factors (SCFs) of circular hollow section CHS brace-to-H-shaped section T-connections under axial compression. This type of welded joints is used increasingly in steel construction. However, its fatigue design is not covered by codes, and its fatigue strength has not been given the deserved attention by researchers.  This research, however, bridges the gab on SCFs in this type of welded connections when being loaded in axial compression. here, parametric study based on the numerical analysis was performed to evaluate the effect of CHS brace diameter to H-shaped chord flange width ratio (β), H-shaped chord flange width to thickness ratio (2γ) and CHS brace thickness to H-shaped chord flange thickness ratio (τ) on SCFs in the brace and the chord of the connection. Based on practical considerations, the validity range of these parameters was 0.3 ≤ β ≤ 0.7, 16 ≤ 2γ ≤ 30 and 0.2 ≤ τ ≤ 0.1. Three-dimensional finite element (FE) study using commercial software ABAQUS was performed to study the hot spot stress distribution and hence SCFs in this type of welded joints. To begin with, the results of FEM were verified against available experimental data and good agreement was achieved. Afterwards, 48 joints were modeled in Abaqus to study the effect of geometrical parameter on SCFs in brace and chord. Based on the results of this extensive study, the effect of geometrical parameters was revealed. The paper, thus, shows that whilst β increases, SCFs in the brace and chord increases. Moreover, increasing the parameter 2γ results in an increase in SCFs in the two members. However, the change in τ has no significant effect on the SCFs in the brace or the chord. Values of SCFs are found to be between 2 and 7.
