Effect of Omega-3 Polyunsaturated Fatty Acids on Inflammatory Biomarkers in Chronic Obstructive Pulmonary Disease
Authors: Al-Haidose Amal
Published: December 2020

Chronic obstructive pulmonary disease (COPD) is a chronic progressive inflammatory disease characterised by airflow limitation. Several pro-inflammatory markers are thought to be involved in the pathogenesis of COPD. Cigarette smoking is a major risk factor for COPD, and diet may be a modifiable risk factor for its progression & management. Dietary supplementation with omega3 polyunsaturated fatty acids (omega-3 PUFAs) may be effective therapeutically in patient COPD. Aim: To determine the plasma basal level of inflammatory biomarkers in the study population, to determine the inflammatory biomarkers release from Peripheral blood mononuclear (PBMCs), and to investigate the effect of omega-3 PUFAs, on inflammatory biomarkers released from PBMCs. Methods: Blood samples were collected from 42 subjects; patients with COPD, 15 healthy smokers (HS), and 12 healthy groups (HNS). Selected biomarkers level was measured in Plasma and PBMCs by ELISA. Individual lipid profile analysis was carried out on RBCs fraction. Result: Plasma high levels of CRP and Fibrinogen and low level of CC-16 were observed in COPD patients when compared with healthy controls. The basal release of IL6, IL8, TNFα, and CD31 from PBMCs was significantly differing in COPD and HS groups compared to HNS group. Omega-3 PUFA (EPA and DHA) reduce IL-6, IL-8 and TNF-α release from PBMCs. The fatty acid composition of the erythrocyte membranes in patients group was unmodified. Discussion: This study showed that high level of several inflammatory biomarkers that were detected systemically in COPD group might associate with the disease systemic inflammation. EPA and DHA possess the ability to reduce the cytokines production from COPD inflammatory immune cells. Additionally, no correlation was observed between fatty acid profile analysis and COPD.
A Decision Analytical Model Investigating Cost-Effectiveness of Erlotinib
Authors: Alam Mohammed
Published: December 2020

Background: A decision analytical model investigating cost-effectiveness of Erlotinib was submitted to the UK NICE (National Institute for Health and Care Excellence), which was not based on actual health-state transition probabilities, leading to structural uncertainty in the model. The study adopted a Markov state-transition model for investigating the cost-effectiveness of Erlotinib versus Best Supportive Care (BSC) as a maintenance therapy for patients with non-small cell lung cancer (NSCLC). Methods: Unlike manufacturer submission (MS), the Markov model was governed by transition probabilities, and allowed a negative post-progression survival (PPS) estimate to appear in later cycle. Using published summary survival data, the study employs three fixed- and time-varying approaches to estimate state transition probabilities that are used in a restructured model. Results: Post-progression probabilities and probabilities of death for Erlotinib were different than fixed-transition approaches. The best fitting curves are achieved for both PPS and probability of death across the time for which data were available, but the curves start diverging towards the end of this period. The Markov model which extrapolates the curves forward in time suggests that this difference between a time-varying and fixed-transition becomes even greater. Our models produce an ICER of £54k -£66k per QALY gain, which is comparable to an ICER presented in the MS (£55k/QALY gain). Conclusions: Results from restructured Markov models show robust cost-effectiveness results for Erlotinib vs BSC. Although these are comparable to manufacturer submissions, in terms of magnitude, they vary, and which are crucial for interventions falling near a threshold value. The study will further explore the cost-effectiveness of therapies for NSCLC in Qatar.

Published: December 2020

In this project, the hybrid testbed architecture is selected for the development of ICS testbed where the Tennessee Eastman (TE) plant is simulated inside PC and the remaining components are implemented using real industrial hardware. TE plant is selected as the industrial process for the developed cybersecur ity testbed due to the following reasons. First, the TE modTheel is a wellknown chemical process plant used in control systems research and it dynamics is well understood. Second, it should be properly cont rolled otherwise small disturbance will drive the system toward an unsafe and unstable operat ion. The inherent unstable open-loop property of the TE process model presents a real-world scenario in which a cyberattack could represent a real risk to human safety, environmental safety, and economic viability. Third, the process is complex, coupled and nonlinear, and has many degrees of freedom by which to control and perturb the dynamics of the process.

Published: December 2020

Unnecessary stopping at signalized intersections during yellow interval reduces traffic flow efficiency. The aim of this driving simulator study was to investigate the impact of an advanced countdown system on traffic flow efficiency during yellow interval at signalized intersections. The experiment was conducted using a driving simulator at Qatar Transportation and Traffic Safety Centre, Qatar University. Sixty-seven volunteers with a valid Qatari driving license participated in the study. Three signalized intersections for three scenarios were designed with the north bound of the Corniche road in the city of Doha as the real-life reference context. The control scenario was an untreated typical signalized intersection (default) with the signal order of green-yellow-red. The signal order was changed to green-flashing green-yellow-red in the condition with 3 seconds advanced flashing. In the third scenario, green LED lights were used as an advanced countdown system and was compared with a default traffic signal with order green-yellow-red and a flashing green traffic signal with order green-flashing green-yellow-red. The LED lights were installed over a 100 m stretch of the road surface with spacing of 5m. More specifically, these ground lights were integrated in the pavement marking strips indicating lane division and edge lines. Light units were flashed green, 3 seconds prior to the yellow interval, and then turned off one by one in sequential order towards the intersection at a predetermined speed. The system was aimed at providing advanced information and visualizing the inter-green period by means of a countdown system as a way to improve traffic flow efficiency. Study results showed that compared to the other two scenarios, drivers’ utilized the yellow interval in a better way in the scenario with green LED lights. Furthermore, results from binary logistic regression showed that probability of crossing the intersection was 30 and 2.6 times higher in the scenario with green LED lights compared to the flashing green and control scenarios, respectively. Regarding the red light running occurrences, there was no significant differences between the scenarios. Taking into account the results from this study, we recommend jurisdictions to further evaluate G-LED as a potentially effective treatment for increasing traffic flow efficiency during the inter-green period at signalized intersections.
AI-powered Motion Interaction for 3D Cultural Heritage
Authors: Belhi Abdelhak , Bouras Abdelaziz
Published: December 2020

Museums and cultural institutions, in general, are in a constant challenge of adding more value to their collections. The attractiveness of assets is practically tightly related to their value obeying the offer and demand law. New digital visualization technologies are found to give more excitements, especially to the younger generation as it is proven by multiple studies. Nowadays, museums around the world are currently trying to promote their collections through new multimedia and digital technologies such as 3D modeling, Virtual Reality (VR), Augmented Reality (AR), serious games, etc. However, the difficulty and the resources required to implement such technologies present a real challenge. Through this poster, we propose a 3D acquisition and visualization framework aiming mostly at increasing the value of cultural collections. This framework preserves cost-effectiveness and time constraints while still introducing new ways of visualization and interaction with high-quality 3D models of cultural objects. Our framework leverages a new acquisition setup to simplify the visual capturing process by using consumer-level hardware. The acquired images are enhanced using frame interpolation and super-resolution. A photogrammetry tool is then used to generate the asset 3D model. This model is displayed in a screen attached to the leap motion controller, which allows hand interaction without having to deal with sophisticated controllers or headgear allowing almost natural interaction.

Published: December 2020

Crowd management is an essential task to ensure the safety and smoothness of any events. Using the novel technologies including surveillance cameras, communication technics between security agents, the control of the crowd has become easier. However, the sue of these technics is still not perfectly effective. This paper presents an approach for managing the crowd at the entrance of event (festival, stadium...) using surveillance cameras. Using cameras and some panels in each entrance, the crowd density is extracted and illustrated in each panel. So, before reaching any gate, the people can see the available and the not crowded gate to reach the target. The proposed technique helps not just in smoothing the motion of the crowd but also minimize the crowdity and abnormal behaviors of the people.

Published: December 2020

Introduction: Virtual reality (VR) and augmented reality (AR) are used as simulation models in student-patient interactive medical education and shown to enhance learning outcomes. The rise in global burden of infectious diseases and antibiotic resistance world-wide prompt immediate action to combat this emerging threat. Catheter associated urinary infections (CAUTI) are the leading cause of hospital-acquired infections. The aim of this research is to develop a virtual reality (VR) based educational tool depicting the process of CAUTI caused by antibiotic resistant bacteria. The VR-CAUTI module is designed to provide insights to health care providers and community which help in reducing the burden of antibiotic resistant infections. Material and methods: The VRCAUTI module is designed using tools including Blender, Cinema4D and Unity to create a scientifically accurate first-person interactive movie. The users are launched inside a human bladder that needs to be drained. They can witness the insertion of a medical catheter into the bladder to drain the urine. Bacteria adhere to the catheter to establish colonization and infection. An interaction between antibiotic molecules and bacteria in the biofilm is observed later. After designing the 3D models, a highlight of the interaction between models, taken from the storyboard, is used to determine the necessary animation. Moreover, dialogue that facilitates the understanding of infections and antibiotic resistance is recorded. This is followed by the assembly of the module on Unity, and enrichments such as lights and orientation. Results and conclusion: This VRCAUTI module is the proof-of-concept for designing detailed VR based scientifically very accurate medical simulation that could be used in medical education to maximize learning outcomes. VR based modules that have the potential to transform and revolutionize learning experience and render medical education compatible with the IoT in the current 4th industrial revolution.
How to Attack a Disconnected Computer
Authors: Fezooni Abdulhady Younes , Ghannoum Ehab Ahmad , Ayesh Malek Ahmad , Malluhi Qutaibah
Published: December 2020

This poster presents how a disconnected computer, that has no network access, can be attacked to retrieve data. Air-gapped devices are thought to be an impenetrable setup because the device is disconnected from the network and cannot be reached by an attacker. Therefore, an infected airgapped computer cannot affect others around it preventing any potential information leaks. People believe/assume that leaking information from an air-gapped machine is impossible. This research effort invalidates this assumption by exploring possible covert channels to get data from victim machines. We take advantage of a hidden acoustic channel that employs the computer speakers and a tiny audio recording device to communicate sensitive data over inaudible near-ultrasonic signals. Data stored on this device can then be processed and displayed as useful information on the attacker’s computer. Hacking methods and the search for new system exploits are being continuously developed and new techniques to obtain data unlawfully are on the rise. Therefore, this work alerts organizations regarding potential threats that they typically ignore by assuming that air-gapped systems are safe. In the past, security researchers have not devoted sufficient time and effort to innovate counter measures for such niche but capable attacks. Spreading awareness is one of the main objectives of this project. This is done by demonstrating that data can be stolen from an ‘air-gapped’ computer, by using methods that people neglect to consider when coming up with plans to protect their computers from attackers. An experiment, such as this, will hopefully push the security field researchers and developers to explore the uncommon methods of unlawful data acquisition and their prevention.

Published: December 2020

Introduction: In Qatar, while most of the country’s demographic situations have been widely studied, much less attention has been paid to the determinants of Qatari women’s sociodemographic characteristics and the prevalence of family planning methods. This raises the following question: How, and to what extent, do population dynamics that stratify national populations by age; sex; marital status; and level of education, income, and employment contribute to the declining of fertility rate and cause mortality differentials in Qatar. Materials and methods: Data from a 2018 fertility survey project with a random sample of 607 Qatari households, collected via personal interviews using a questionnaire and a computer assisted personal interview, by the Social and Economic Survey Research Institute at Qatar University, was examined based on a multi-dimensional model. The data were analyzed using logistic and Poisson regression techniques. Results: The data show that Qatari women’s total fertility rate is 3.2, with women in the 20–29 age group having the highest fertility rates. Evaluating the effects of women’s educational attainment and employment status revealed no significant factors influencing the agespecific fertility rate of Qatari women. In addition, the results indicate that the most common contraceptive method currently used among Qatari women is pills (29%), and their use is more prevalent among older Qatari women who have had more children than among younger Qatari women with fewer children. Conclusion/ future direction: The paper provides comprehensive policy recommendations for increasing the reproductive rate in Qatar by providing supporting programs to increase the total fertility rate and childbearing rates among Qatari women. It also promotes the provision of high-quality family planning services.

Authors: George Iniodu , Edim Hannah , Edet Emmanuel
Published: December 2020

Background: Safety concerns over the use of chemical-based pesticides are provoking intense studies and application of bio-pesticides in disease control and agriculture. Aim: This qualitative study was aimed at testing the repellent efficacy; and suitability of Cymbopogoncitratus (Lemongrass) for the development of natural product-based mosquito repellent. Method: Cymbopogon oil (75ml) was extracted from 200g of fresh Lemongrass leaves using Soxhlet method with n-Hexane as solvent. Human volunteers were topically treated with 2ml and 6ml of Cymbopogon oil applied on exposed areas of the body at night; and observed for 4hrs 30mins. Direct test on mosquitoes in captivity was conducted using a 2-chambered insect box treated with 4 ml of oil in one chamber. Results: Human subjects were free from mosquito bites for 3 hours. Mosquitoes in captivity exhibited active movement away from oil-treated chamber of the box within the first minute of application; 43% repellency and 100% mortality were recorded after 18 minutes. Conclusion: Findings suggest that Cymbopogoncitratus extracts could be used for the production of potent chemical-free and safe mosquito repellent and insecticide for vector control in the fight against malaria and other mosquito-vectored diseases. However further studies and qualitative analyses are necessary to determine suitable concentrations for human topical application.

Authors: George Iniodu , Mbere-obong Davison
Published: December 2020

Effective control efforts on Lymphatic filariasis (LF) are hindered by paucity of reliable data on spatial distribution of the disease. Aim: This study was aimed at mapping and describing the transmission pattern of lymphatic filariasis in order to identify high risk zones of infection in Cross River State (CRS), to guide intervention programmes. Method: An 8-year case record (2006-2013) of Lymphatic filariasis in the 18 local government areas (LGAs) of CRS was mapped using geographical information system, (GIS); employing the graduated colour map with natural break classification method. Thematic (LF incidence) maps generated in ArcView 3.1 were overlaid on vegetation and natural drainage maps of the state. Data on seasonal incidence were mapped through aggregation of attribute data (LF cases) by months. Data analysis was through thematic mapping and descriptive statistics. Results: Thematic maps displayed spatial variation in the distribution of LF in the state; showing Ogoja LGA with highest incidence (61.25%) of the 800 reported cases; Ikom, the lowest; 1(0.125%) and zero case in 7 LGAs. There were no visually remarkable patterns to suggest strong influence of vegetation and natural drainage on transmission. Greater proportion (82.12%) of cases was recorded in the dry season. Conclusion: The study has produced prevalence map of LF in the state, which could guide intervention programmes; and has also revealed paucity of data at the disposal of healthcare authorities, a situation that could hinder large scale intervention. Findings identify poor health-seeking behavior of the population and poor disease surveillance strategies in the state. Community health education, strengthening of public health apparatus and interventions through mass drug administration and integrated vector control, are recommended.

Authors: Devi Seema
Published: December 2020

Goods and Service Tax (GST) is a Value Added Tax (VAT), which hypothetically to be put into effect from April 2010, but because of conflicting interest of stakeholders and various political controversies it has been passed in both Houses of Parliament on Aug. 3, 2016. It alone indirect tax which influence the whole economy directly. It is aspiring as iron out wrinkles of current indirect taxes and has a far-reaching impact on GDP. India is a centralized constitutional economy. GST is applicable on all States and Union territories, known as CGST (Central Goods & Services Tax) and SGST (State Goods & Services Tax). The ill effects of cascading can be mitigated after tie up the central and states taxes in solitary tax. The economy is expected to pave the way of common national market as it will provide benefits to consumer by reducing overall tax burden of goods, which is currently estimated at 25% to 30%. Thus, introduction of Goods and Service Tax (GST) is a gigantic tax transform in contemporary ancient times.            

Ignorance of law is no excuse but is liable to panel provisions, hence why not start learning GST and avoid the cost of ignorance. We all need to know, whether GST is willingly or imposed. This paper describes a brief introduction of current indirect tax structure and GST in India. What are challenging factor in implementation and what can be the opportunities of GST in India.

In the first half of the ninth century AD, a new dynasty emerged in Malwa which became famous as Parmar dynasty. The first king of this dynasty is considered to be Upendra. He started his life as a feudatory of the Rashtrakutas or Gurjara Pratiharas.

The official son of Upendra was Varisingh I. No incidents of his reign are known. The successor of Varisingh was Seyak I. Padmagupta does not mention Varisinh and Siayak I. It is inferred that these two were feudal rulers of ordinary merit. After the death of Seek I, his son Vakpati I became the first king. Dr. According to Ganguly, he fought with his master Rashtrakuta king Indra III against the Pratihara king Mahipal. No other events of his reign are known.

La lectura y el futuro profesor: una aproximación a sus creencias acerca de la lectura
Authors: González Ramí­rez Carolina , González Figueroa Marcelo , Lobos Guerrero Constanza , Valenzuela Jorge , Muñoz Carla
Published: December 2020

Con el objetivo de indagar en las creencias de futuros docentes acerca de la lectura, se realizó un análisis de contenido textual de tipo mixto. Participaron 364 docentes en formación de Educación Básica (n = 202) y Educación Parvularia (n = 162) provenientes de nueve universidades chilenas. Los discursos de estos futuros docentes dan cuenta de creencias diversas referentes a la lectura (inter e intrasujetos) que van desde la herramienta hasta la práctica cultural. Contra lo esperado, se constata empí­ricamente un predominio de nociones caracterizadas por un bajo número de facetas y por un énfasis en definiciones desde lo experiencial, independientemente de la carrera y de los años de formación. Así­, la clasificación de creencias, considerando de manera simultánea la riqueza y la especialización, muestra una alta concentración en el tipo experiencial simple, es decir, con baja especialización y baja riqueza (71%), mientras que el tipo especializada compleja (alta especialización y riqueza) solamente alcanza un 11%. Junto con discutir las implicancias de estos hallazgos para la práctica pedagógica y la formación de profesores lectores, se aporta adicionalmente un esquema de análisis para las creencias en torno a la lectura que puede contribuir a nuevos estudios relacionados con este tópico.

Robust fractional order sliding mode control for solar based DC-AC inverter
Authors: SAHEB Shaik Silar , GUDEY Satish Kumar
Published: December 2020

Fractional order sliding mode control (FOSMC) strategy for a solar based DC-AC inverter is presented in this work. First FOSMC is implemented to voltage source inverter with a fixed DC input voltage of 400V to drive a load of 2.3 kW at a power factor of 0.8 lag. Here load voltage and current through capacitor as state variables and a linear sliding surface is considered. FOSMC using Gao’s reaching law is derived for inverter circuit. FOSMC is implemented at load bus to control output voltage of inverter with linear and nonlinear loads to desired values. FOSMC controls the output voltage with good voltage regulation, less steady state error of 1.32 %, settling time of 0.15 ms, good dynamic response, and convergence to origin with less chattering compared to classical SMC. FOSMC based solar based VSI is presented. The maximum power from PV array is extracted using P&O MPPT algorithm. A boost converter is used to step up input voltage of 200 V to 400 V. P-V and I-V characteristics are obtained for a typical solar cell of 2.5 kW FOSMC requires less control efforts to obtain a pure sinusoidal output voltage waveform of 230 V (rms) with output voltage THD of 0.135% well within IEEE standards. PSCAD/EMTDC v4.6 is used for simulation work.
Análisis morfométrico de los principales tributarios del río Salí en la cuenca de Tapia – Trancas a partir del procesamiento en SIG y sensoramiento remoto
Authors: Bustos María Soledad , Georgieff Sergio Miguel
Published: December 2020

El análisis morfométrico provee una descripción de las características de las redes de drenaje de una región y permite anticipar una respuesta frente a los fenómenos climáticos. En este trabajo se presentan los resultados del análisis morfométrico realizado sobre los principales tributarios del río Salí en la cuenca de Tapia – Trancas, Tucumán, Argentina. Los parámetros morfométricos fueron calculados en base a la metodología de Horton - Strahler con apoyo de herramientas de sistemas de información geográfica y datos de sensoramiento remoto (modelo de elevación digital SRTM). La relación entre orden de los ríos, longitud media y el número de ríos, sigue tendencias geométricas. El coeficiente de almacenamiento indica que en los ríos Choromoro, Tapia y Acequiones (valores altos de Rho) se dan mayores tiempos para alcanzar los caudales de punta y los procesos erosivos están atenuados. Los valores más altos del coeficiente de torrencialidad caracterizaron a las cuencas de los ríos Candelaria, Tala y arroyo India Muerta, indicando mayor ocurrencia de ﬂujos torrenciales e inundaciones aluvionales veloces. La extensión media del escurrimiento fue mayor en los ríos Tapia y Choromoro lo cual implica un mayor tiempo para alcanzar los caudales de punta. El río Acequiones fue el de mayor densidad de drenaje indicando que la red hidrológica se desarrolla sobre rocas más impermeables. La frecuencia de ríos (Fr) muestra un escaso desarrollo en la subcuenca del arroyo India Muerta, que se condice con su baja densidad de drenaje y escasa superficie. Las subcuencas de los ríos Choromoro, Vipos y Acequiones, tienen mayores valores de Fr lo cual representa una mayor disponibilidad de agua en superficie, menor permeabilidad de los terrenos y mayor susceptibilidad a la erosión. El análisis morfométrico en base al procesamiento de datos de sensores remotos permite caracterizar las redes de drenaje de los tributarios del río Salí en la cuenca de Tapia–Trancas e identificar las subcuencas que presentan una mayor susceptibilidad a la erosión.

Adesmia trijuga es un arbusto espinoso, micrófilo, nativo, perenne; crece entre 1100-3000 m snm, en regiones montañosas de quebradas húmedas o zonas áridas y rocosas; vulgarmente es conocida como “cuerno de cabra”, “añagua” o “suncho”. A. trijuga es polimórfica de hojas pinnadas con 3-5 pares de folíolos, forrajera, utilizada como leña y de amplia distribución en Argentina y Chile. Los antecedentes se refieren únicamente a la citogenética de poblaciones de la Región de Cuyo. El objetivo fue caracterizar los parámetros micrográficos vegetativos, histoquímica y citogenética de A. trijuga en poblaciones del NOA. Se recolectaron, al azar, 5 individuos en poblaciones ubicadas en Jujuy, Salta y Tucumán. El material fue fijado en FAA y herborizado; se aplicaron técnicas anatómicas, histoquímicas y citogenéticas convencionales. Los resultados evidenciaron hojas paripinadas, micrófilas, con folíolos de lámina entera, simétrica, obovada y venación pinnada-camptódroma-eucamptódroma. Foliolos anfistomáticos, pubescentes en ambas epidermis, con tricomas eglandulares y glandulares de 3 tipos; células epidérmicas isodiamétricas a rectangulares de paredes rectas a curvas con cutícula estriada; estomas anomocíticos, hemibraquiparacítico, braquiparacítico, anfibraquiparacítico, hemianfibraquiparacítico y hemianficiclocítico; mesofilo equilateral; haces vasculares colaterales con casquete de esclerénquina hacia floema y vaina parenquimática. Pecíolo subcircular, con tricomas eglandulares y glandulares idénticos a los de la lámina; 2-3 estratos de clorénquima en empalizada subepidermico; 5 haces vasculares colaterales. Espinas circulares con tricomas idénticos a los de la lámina y el pecíolo, crecimiento secundario con abundante esclerénquima. Tubos e idioblastos con fenoles se presentan en el mesofilo de la hoja, médula del pecíolo y en la espina. El número cromosómico fue de 2n=20 cromosomas. Los elementos de valor diagnóstico son: tipo de tricomas, cantidad y posición del tejido de sostén, idioblastos y tubos productores de fenoles y el número cromosómico.

Published: December 2020

In recent years, companies' actions towards factors of production have multiplied. The human dimension is increasingly present in decisions and companies feel socially responsible. The sustainability of companies necessarily requires limiting the negative environmental effects because of these production activities. Ethical finance in general, whether Islamic or not, is a growing demand on the part of consumers and states. The aim of this paper is to assess the risk of two ethically responsible indices such as S&P500 Shariah index and S&P500 Environment and Socially Responsible index. In this paper, we will conduct a comparative study of market risk on two ethically responsible indices: the Islamic Index of the Shariah (S&P500 Shariah index) and the S&P500 Environment and Socially Responsible index during the period from 30/09/2010 to 21/09/2018. The evolution of the market will be represented by the general index of the S&P500. To do this, we use different approaches to value at risk such as VaR parametric approach, VaR non-parametric approach and the Theory of Extreme Values approach. Our results show that, on the one hand, the S&P500 Environment and Socially Responsible index is less risky than the S&P500 Shariah index and the S&P500 index. On the other hand, the S&P500 Shariah index is at low risk when yields are extreme. We conclude that the S&P500 Environment and Socially Responsible index is less risky than the Shariah S&P500 Index when you consider that yields are moving under normal market conditions.

Published: December 2020

Neste artigo propomos conduzir uma análise da obra literária Garotas Mortas (2018), de autoria da escritora argentina Selva Almada. A partir das narrativas imbricadas na obra, empreenderemos discussões acerca do feminicídio e de suas raízes históricas e culturais, recorrendo, para tanto, aos estudos feministas promovidos por Perrot (2007) e Muraro (1997). Estabelecendo diálogos com as proposições de Cixous (2017), identificaremos a obra analisada como manifestação da escritura feminina, posto que constrói espaços para a reverberação de vozes até então silenciadas e prega a emancipação do corpo feminino. Traçaremos relações, ainda, entre corpo feminino, gênero, feminicídio e política.

Nos dois lados do Atlântico
Uma análise contrastiva entre PE e PB na tradução audiovisual de Madagascar
Authors: Lucente Giovanna
Published: December 2020

This essay is a comparative study of European (EU) Portuguese and Brazilian (BR) Portuguese in the context of oral, low-monitored language level where the two variants differ the most. The analysis is performed on audiovisual material, specifically the dubbed versions of Madagascar, that provide examples of authentic language used by contemporary native speakers. The first section of the article focuses on building a theoretical framework based on the existing studies on children’s literature and audiovisual translation with a focus on dubbing. The theoretical introduction and the different strategies used for the localization of the dialogues, allow us to draw hypotheses on diatopical differences of the Portuguese language in Portugal and Brazil. The last section of the article compares EU and BR Portuguese on morphosyntax, lexicon and cultural level, using specific examples taken from the movie Madagascar.
