Large Eddy Simulations with Conjugate Heat Transfer (CHT) modeling of Internal Combustion Engines (ICEs)
Authors: Wu Angela , Keum Seunghwan , Sick Volker 
Published: May 2019

In this study, the effects of the thermal boundary conditions at the engine walls on the predictions of Large-Eddy Simulations (LES) of a motored Internal Combustion Engine (ICE) were examined. Two thermal boundary condition cases were simulated. One case used a fixed, uniform wall temperature, which is typically used in conventional LES modeling of ICEs. The second case utilized a Conjugate Heat Transfer (CHT) modeling approach to obtain temporally and spatially varying wall temperature. The CHT approach solves the coupled heat transfer problem between fluid and solid domains. The CHT case included the solid valves, piston, cylinder head, cylinder liner, valve seats, and spark plug geometries. The simulations were validated with measured bulk flow, near-wall flow, surface temperature, and surface heat flux. The LES quality of both simulations was also discussed. The CHT results show substantial spatial, temporal, and cyclic variability of the wall heat transfer. The surface temperature dynamics obtained from the CHT model compared well with measurements during the compression stroke, but the absolute magnitude was 5 K (or 1.4%) off and the prediction of the drop in temperature after top dead center suffered from temporal resolution limitations. Differences in the predicted flow and temperature fields between the uniform surface temperature and CHT simulations show the impact of the surface temperature on bulk behavior.
AS FIGURAS DE LINGUAGEM E SUAS TRADUÇÕES EM NOTRE-DAME DE PARIS:
Authors: Silva Jocileide 
Published: May 2019

As figuras de linguagem são recursos estilísticos que podem enriquecer um texto. Victor Hugo, no capítulo “Lasciate ogni speranza” (“Deixai toda esperança”), da obra Notre-Dame de Paris, faz uso desse recurso para descrever o escuro, o terrível e o monstruoso espaço da masmorra, na qual Esmeralda foi presa. Objetiva-se aqui analisar as figuras de linguagem presentes no texto-fonte e que servem para caracterizar esse ambiente e, posteriormente, traduzi-las, a fim de verificar sua permanência e adequação no texto-alvo. Essa análise se apoiará nos estudos de Pierre Fontanier sobre as figuras de linguagem, e nos estudos de Paul Ricœur e Marivonne Boisseau, no que se refere à tradução. Para abordar o grotesco e a monstruosidade, partiremos das reflexões de Victor Hugo, Edmond Burke e Claude Kappler.
ANALISANDO PADRÕES DE COLOCADOS COMO TRAÇOS DO ESTILO DA TRADUÇÃO:

Neste estudo exploratório descreve-se o estilo de duas traduções de Heart of Darkness (CONRAD, 1902), uma espanhola (FOLCH, 2007) e uma do português europeu (RODRIGUES, 2009), usando um corpus paralelo. O estudo tem como aporte teórico os estudos de estilo da tradução e utiliza a metodologia dos Estudos da Tradução Baseados em Corpus – ETBC. Toma-se como base Stubbs (2003, 2005), que defende o uso de informações quantitativas para um estudo mais detalhado da obra de Conrad. Stubbs (2003, 2005) afirma que um dos temas principais da obra de Conrad é realizado pela repetição de itens lexicais que denotam incerteza e impressões vagas, especialmente pelo uso elevado do lema seem* (79). Stubbs (2005) chama atenção para o fato de que o lema seem*, que não é comumente um verbo de frequência alta em textos ficcionais, está entre os 10 verbos mais frequentes na obra. Investigando-se a alta frequência do lema parec* nos dois textos traduzidos (TTs) referidos verificou-se que em Folch (2007) a frequência é maior (111) em relação ao texto fonte (TF), pois se observa que o tradutor utilizou essa forma para a tradução de outros itens que não aqueles derivados do lema seem*. Rodrigues (2009) apresenta uma frequência um pouco maior do lema parec* (126) e realiza 15 escolhas diferentes para a tradução dos itens lexicais derivados de seem*. Com base nesses dados, procura-se descrever as mudanças significativas que ocorreram no estilo dos textos traduzidos com relação ao uso do verbo parecer.

Published: May 2019

Rawapening merupakan salah satu danau yang keberadaannya mempunyai peranan sangat penting bagi kehidupan masyarakat sekitarnya bahkan dikawasan sebelah hilirnya. Kualitas ekologi perairan Rawapening dari tahun ke tahun terus menurun, baik daya tampungnya maupun kondisi kualitas airnya. Peranan sungai sungai dengan kondisi daerah tangkapannya turut menentukan keberadaan kualitas lingkungan ekologis Rawapening. Tujuan dari studi ini adalah untuk mengetahui kondisi ekologi lahan koridor sungai sungai yang masuk Rawapening terkait isu penurunan kualitas ekologi Rawapening. Tata guna lahan di sekitar koridor sungai ternyata merepresentasikan kondisi tataguna lahan DAS Rawapening yaitu dari hutan, kebun campuran, semak belukar, sawah irigasi dan sawah tadah hujan. Kondisi kualitas fisik kimia tanah juga sangat bervariasi namun secara umum mempunyai tingkat kesuburan yang baik. Akan tetapi hasil studi menunjukkan terjadi penurunan degradasi lahan terkait perubahan tataguna lahan terutama perubahan penurunan luas kebun campuran dan berubah menjadi pola penggunaan permukiman dari 12431 Ha pada tahun 2003 menjadi 10625 Ha pada tahun 2010. Regim tampungan air danu Rawapening yang ekstrim antara pada musim penghujan dan kemarau juga disebabkan oleh kondisi kualitas koridor sungai yang sudah terdegrdasi terutama perubahan pola penggunaan lahan dari daerah pengalirannya.

Analysis Of Risk Factors Oxidative Stress In Obesity Women
Authors: Hidayati Alpha Olivia , Hardani Ernawati 
Published: May 2019

Obesity is a condition of imbalance in the number of calories entered by the number of calories where the excess is heaped up as body fat. Obesity followed by an increase in fat metabolism will cause Reactive Oxygen Species (ROS) production to increase. This condition causes oxidative stress. Indicators of oxidative stress can be observed from plasma levels of Malondialdehyde (MDA). This study aims to determine the risk factors for oxidative stress in obese women.
The results of this study indicate that high fat intake (> 60 g / day) is at risk of increasing MDA-P levels twice. Low fiber consumption (<30 gr / day) gives the risk of an increase in MDA-P levels of 2.09 times. Poor physical activity is a risk factor for MDA-P increase of 1.15 times. High cholesterol (> 200mg / l) and LDL (> 130 mg / l) and low HDL (≤45mg / dl) levels are at risk of increasing MDA-P levels by 1.02 times (cholesterol), 1.13 (LDL) ) and 1.12 (HDL).
Based on this study it can be concluded that high fat intake, low fiber intake, low physical activity, high cholesterol and HDL levels and low HDL levels are risk factors for oxidative stress.

Published: May 2019

<p>The policy of closing Jatibaru Raya Road on December 22, 2017, has caused new problems because the road closure has caused public losses. The public policy applied by Governor Anies indicated that he had a strong political contract with the community and one of the powerful figures in Tanah Abang so that the policy benefited the people of Tanah Abang who had been disciplined during the previous governor's term. These issues are very relevant to be studied using qualitative methods with a grounded approach to obtain material and in-depth information. Regarding the road closure policy, the existing policy is seen as a step in the realization of Anies campaign promises to establish 200,000 MSMEs at the time of the DKI Jakarta Pilkada in 2017. The public policy for road closure is basically an incremental policy because there are not many policy programs that have been running and was designed during the previous governor's term. The implementation of this policy has made Governor Anies considered maladministration by the Ombudsman, thus giving rise to recommendations for the position of Anies as governor.</p><p><sup> </sup></p><p><strong><em>Keywords: </em></strong><em>Public Policy; Inkremental;<strong> </strong>Maladministration.</em></p>

Published: May 2019

OBJECTIVEIndocyanine green videoangiography (ICGVA) has been used in many neurosurgical operations, including vascular and brain tumor fields. In this study, the authors applied ICGVA to intracranial meningioma surgery and evaluated it usefulness with attention to collateral venous flow.METHODSForty-two patients with intracranial meningioma who underwent ICGVA during microsurgical resection were retrospectively analyzed. For ICGVA, the ICG was injected intravenously at the standard dose of 12.5 mg before and/or after tumor resection. Intravascular fluorescence from blood vessels was imaged through a microscope with a special filter and infrared excitation light to illuminate the operating field. The authors assessed the benefits of ICGVA and analyzed its findings with preoperative radiological findings on MRI.RESULTSICGVA allowed real-time assessment of the patency and flow direction in very small peritumoral vessels in all cases. A safe dural incision could also be done based on information from ICGVA. The collateral venous channel due to venous obstruction of tumoral compression was found in 10 cases, and venous flow restoration after tumor resection was observed promptly after tumor resection in 4 cases. Peritumoral brain edema (PTBE) was observed on preoperative T2-weighted MRI in 19 patients. The presence of collateral venous circulation or flow restoration was significantly related to PTBE formation in multivariate analysis (p = 0.001; HR 0.027, 95% CI 0.003–0.242).CONCLUSIONSICGVA, an excellent method for monitoring blood flow during meningioma resection, provides valuable information as to the presence of venous collaterals and flow restoration. Furthermore, the fact that the presence of venous collaterals was found to be associated with PTBE may directly support the venous theory as the pathogenesis of PTBE formation.
The Flexural Motions of a Floating Ice Sheet Induced by Moving Vehicles
Authors: Eyre D. 
Published: May 2019

AbstractAn extensive series of tests has been conducted on a Roating ice sheet on a deep, fresh-water lake. A variety of vehicles were driven a long an instrumented test track at a wide range of speeds, producing several characteristic patterns of ice and water response that have been recorded and analysed in detail. Tests were repeated at different stages of ice growth to accommodate changes in physical conditions. The use of a vibration transducer and a new type of deflectometer has permilled the study of many primary and secondary effects. As vehicle speed is increased, the ice and water pass through four characteristic modes of response, culminating in a wave effect at the higher speeds. It has been shown that the ice and water waves travel consistently at the speed of the vehicle. This factor has been used to modify a simple ice-wave theory, which then predicts a linear variation of wave frequency with vehicle speed that can be expressed in a universal form for deep -water conditions. The experimental measurements of frequency confirm this universal variation. The observed secondary effects include air-coupled Rexural oscillations, hydrodynamic Auctuations and systematic variations in ice fracture intensity with vehicle speed. This last effect leads to the proposition of a new criterion of vehicle safety.
