La fábula de Perseo en la versión de las Metamorfosis ovidianas de Antonio Pérez Sigler = The fable of Perseus in the traslation of the ovidian Metamorphoses by Antonio Pérez Sigler
Authors: Fernández López Esther
Published: April 2021

Entre las traducciones castellanas en verso de las Metamorfosis de Ovidio, la más antigua es la del salmantino Antonio Pérez Sigler, cuya primera edición data de 1580. Eclipsada por la traducción de Sánchez de Viana (1589), de mayor calidad y difusión, la versión de Pérez Sigler ha sido en general poco estudiada y valorada. Se le ha reprochado, además, una dependencia directa de la traducción italiana de Anguillara. Sin embargo, pensamos que el salmantino llevó a cabo en su traducción un trabajo más que digno, tanto por su fidelidad al texto original como por sus méritos poéticos. La presente contribución pretende reivindicar la validez de esta versión castellana, como también la del Diccionario poético que acompaña a su segunda edición (1609). Como muestra del buen hacer de Pérez Sigler nos fijamos en especial en su versión de uno de los episodios del poema ovidiano: la fábula de Perseo, uno de los mitos paganos más difundidos y adaptados a lo largo de la historia de la literatura española.Among the Castilian in verse translations of Ovid’s Metamorphoses, the oldest is that of Antonio Pérez Sigler from Salamanca, whose first edition dates from 1580. Eclipsed by Sánchez de Viana’s translation (1589), of higher quality and more widespread, Pérez Sigler’s version has generally been little studied and valued. It has also been criticized for being directly dependent on the Italian translation of Anguillara. However, we think that the Salamanca-born author did a more than worthy task in his translation, both for his fidelity to the original text and for his poetic merits. The present contribution aims to claim the validity of this Spanish version, as well as that of the Poetic Dictionary that accompanies its second edition (1609). As an example of Pérez Sigler’s good work, we look especially at his version of one of the episodes of the Ovidian poem: the fable of Perseus, one of the most widespread and adapted pagan myths in the history of Spanish literature.

Published: April 2021

O atual cenário energético mundial é de busca por combustíveis mais limpos e novas fontes de energia renováveis, com destaque à utilização de biomassa residual. O presente trabalho busca avaliar as características físico-químicas de briquetes produzidos a partir do bagaço da cana-de-açúcar, bagaço de mandioca e cama de aviário. Os subprodutos passaram por análises antes e após a briquetação. Foram produzidos briquetes com diferentes percentuais de mistura (M1, M2 e M3). Os briquetes produzidos apresentaram valores de eficiência energética, resistência mecânica e densidade aparente e energética coerentes com valores da literatura e de normativas internacionais. Em relação ao teor de cinzas nenhum deles se enquadra nos parâmetros europeus de fabricação de briquetes. A mistura com melhor eficiência energética foi M2, com poder calorífico de 16,41 MJ/kg e também o menor teor de cinzas, de 7,96%, e melhor relação C/H, porcentagem de hidrogênio e de carbono, sendo assim o de maior potencial energético de queima. A utilização de briquetes produzidos a partir de biomassa residual apresenta muitas vantagens, contribuindo em aspectos econômicos, sociais e ambientais.

Were Women “Free” to Divorce in China: The Impact of the Civil Code of the Republic of China Family on Divorce Disputes, 1929-1949
Authors:   History School, Zhengzhou University, Henan, 450000, China, Mingkang Hao
Published: April 2021

The 1930 law The Civil Code of The Republic of China Family, one of the important part of the Civil Code, gave husbands and wives the equal ability to invoke divorce proceedings in the Republic of China. But reality did not reflect the equitability of the law. This paper questions how free women were to invoke divorce proceedings. Many scholars have considered how the Civil Code was an improvement upon previous laws and provided women with many more rights than in the previous century. This paper challenges this narrative by examining publicized divorce proceedings in newspapers and archives in various places in China. It argues from 1928 to 1949 that despite the legal ability to do so, in practice many factors prevented women from making much use of this law. Women struggled with the high economic and time cost to get divorced. Importantly though it offered equitability to invoke divorce proceedings, The Civil Code did not erode the power of custom, the tradition of living within the husband’s family and the limited access of women to work and education, which restricted women’s ability to take advantages of the law. Only women with economic independence and social position were able to use this law to their benefit.

Authors: Ahmed Fazeel Zubair , Kudthni Ravi Hanumanthappa
Published: April 2021

Background: All subjects of MBBS do not have same examination pattern especially concerning to question paper pattern and distribution of marks. As a result, students are experiencing variety of examination patterns during their study. Neither is their uniformity of examination pattern throughout the country nor there is uniformity within a university. In such situation, it would be wise to take feedback from students which could help in redesigning the examination pattern. This study was done to collect students’ opinion regarding current examination methods and possible changes that might be required in existing assessment methods.Methods: Questionnaire based study was done on MBBS second year students of Viswabharathi medical college. Questionnaire consisted of 10 questions about examinations faced by the students. Each question had five options arranged according to 5-point Likert scale.Results: 99 students participated in this study. 51.52% students preferred having two essay questions and 42.42% preferred having one essay question in final theory exam. 52.53% preferred to have 40 marks as weightage of one paper. 50.51% supported having illustration-based questions in their final theory examinations. 79.80% stated that at least 30 days of preparation holidays are required for them before their final exams. 48.48% preferred having five very short answer questions. 48.48% stated that weekend tests conducted by their institute were helpful to them. 66.66% disagreed upon increasing number of questions in final examination. 63.63% agreed on having MCQ’s. 48.48% agreed on having viva voce during every internal examination. Consensus could not be reached upon frequency of institutional tests.Conclusions: This study highlighted certain shortcomings in medical education with respect to examinations. Weightage and number of questions might be increased marginally to have a uniform pattern. Question paper should have more very short answer questions and less essay questions. Illustration based questions should also be introduced. 30 days of preparation holidays must be given before final exams for self-study.

Authors: Naik Payal P. , Panwar Arvindsingh , Patel Swati
Published: April 2021

Background: Tuberculosis is a serious public health issue in India. The treatment regimen followed is Directly observed treatment short-course (DOTS) and Programmatic Management of Drug resistant Tuberculosis (PMDT) approach. In a long period of treatment adverse drug reactions (ADRs) can be an important programmatic issue. Thus, study was undertaken to assess the ADRs caused by antitubercular therapy in indoor patients in a tertiary care hospital at Surat.Methods: The Observational, prospective study was carried out for one year period. The causality was determined by WHO UMC scale and severity was determined by Modified Hartwig and Siegel scale. Chi square test was applied for statistical analysis.Results: Among 255 tuberculosis patients, 85 (33.3%) patients developed ADRs. Occurrence of ADRs was more among females (46.6%). The commonly involved systems are gastrointestinal (40.6%) followed by haematological (17.9%). The most common ADRs observed were nausea and vomiting (21.7%). High percentage of ADRs causing drugs were isoniazid (30.6%) followed by rifampicin (26.1%). Causality assessment showed 60.4% ADRs were possible, 37.7% ADRs were probable and 1.9% ADRs was certain. Severity assessment scale showed 81.1% of moderate, 12.3% of mild and 6.6% of severe grading. Occurrence of ADRs was more among PMDT (60%) in comparison to DOTS therapy (31.06%) [p value = 0.0084 (significant p value < 0.05)].Conclusions: Antitubercular treatment is safer but early detection, management and reporting of ADRs is required to prevent it at initial stage and helps to decrease default rate.

Authors: Meenakshi R. , Nitya S. , Kiruthika S. , Shanthi M.
Published: April 2021

Fixed drug eruptions (FDE) are cutaneous adverse drug reaction characterized by well demarcated erythematous plaques which on removal of the offending agent resolves with residual hyperpigmentation patches at the site. FDE to nitroimidazoles and fluoroquinolones have nevertheless been infrequently reported. Awareness about the adverse reaction to the fluoroquinolone-nitroimidazole combination drug and also the likelihood of recurrence with same or similar drugs and the possible cross reaction is eminent. Hereby we report one such case of FDE to ciprofloxacin/tinidazole combination.

Background: Several links were searched to know the variations in anthropometry and physical characteristics of staff with low back pain (LBP) working in tertiary hospital. Controversy exists between the association of these characteristics with LBP. The study was conducted to understand the relation between physical characteristics and LBP in the south Indian population.

Methods: Ethical approval was obtained from the institutional health research ethical committee. A survey was conducted using a proforma and it was circulated among the staff and doctors in the tertiary care hospital. The validated questionnaires were framed to collect all the physical characteristics and anthropometry of the respondents and history of LBP. The distribution of the parameters are calculated either as mean±two standard deviation, or as count and percentage. The tests used for comparison is the t test and for association is the chi square (𝛘2) test. A p value less than or equal to 0.5 is considered as statistically significant. The data was analysed using the microsoft excel and the minitab (17) software.

Results: The study showed significant positive association of back pain with increase in weight of the subjects, history of back trauma, spinal injections and lifting heavy weights (p value<0.01). There was no significant association of LBA with variables like history of menstrual irregularities and mode of transport.

Conclusions: There is a positive association between LBP with anthropometric features like weight of the patient and also physical characteristics like history of back trauma, spinal injections and lifting heavy weights.

Published: April 2021

Background: Spondylolisthesis is condition in which one vertebra slips over other vertebra. This study has been done to compare the functional outcome and complications of two techniques: posterior lumbar fusion (intertransverse fusion) and posterior lumbar interbody fusion.

Methods: Total 20 patients with spondylolisthesis admitted in a tertiary care centre in Rajasthan were allotted alternatively in posterior lumbar fusion (PLF) group and posterior lumbar interbody fusion (PLIF) group. In PLF, fusion was done by placing bone graft between transverse processes and around facets. In PLIF, fusion was bone by placing cage in between vertebral bodies.

Results: 20 patients were included in our study with female predominance (65%). Mean age was 54.2 years (PLF=58.4 and PLIF=50.2). 70% patients have L4-L5 level spondylolisthesis. Average operative time was less in PLF group, which is statistically significant. Functional outcome was measured by using visual analogue scale (VAS) score and Japanese orthopedics association score (JOAS) at 3 weeks, 3 months and 6 months. There is a significant decrease between preoperative VAS and at 6 months, in both PLF and PLIF group. JOAS was significantly increased at 6 months in both PLF and PLIF group as compared to preoperative score. But difference in JOAS at 6 months is not significant between PLF and PLIF.

Conclusions: Both PLF and PLIF are equally effective for spondylolisthesis. Both techniques have same satisfactory results. As PLIF is more invasive technique, more operative time and more complications are seen.

Background: The purpose of the study was to compare the outcome of distal femur extra articular fractures treated with locking plate and retrograde intramedullary nail.

Methods: 86 patients’ distal femur extra-articular fractures were included in the study. 44 patients were operated with intramedullary nailing; 42 patients were operated with locking plate. Results of the 2 groups were compared with regards to clinical and radiological outcome, intraoperative timing and blood loss. Post-operative status of the patients was evaluated using the visual analogue scale, neer score, knee range of motion and radiological union on plain radiographs. Patients were followed-up at 4 weekly intervals from 8 to 28 weeks and then at 1 year.

Results: Mean operative time and blood loss was less in intramedullary nailing group whereas intraoperative blood loss was less in the plating group. 6 patients developed surgical site infection in the plating group. Mean-time till radiological union was significantly better in intramedullary nailing group. 7 patients in plating group had issues with union (5 non-union, 2 delayed union) whereas 1 patient in IMN group had nonunion. 93% of intramedullary nailing cases were able to bear full weight at 12 weeks compared to 66% cases in plate group. Knee pain at 6 months was more in intramedullary nailing group.

Conclusions: IMN proved to be a better modality of fixation of distal femur fracture fixation in our study in terms of operative time, union rates, infection rates and overall patient outcome if done with proper principles and techniques of intramedullary fixation.

Enhanced Performance of Indirect Vector Controlled Induction Motor Drive with a Modified Type 2 Neuro-Fuzzy Torque Controller in Interfacing with dSPACE DS-2812
Authors: Prasad Repana Ramanjan , Durgasukuamar Gadwala
Published: April 2021

Due to the nonlinearities of the PI controller, the performance of the PI controller is not satisfactory. The gains must be properly selected after changes in control parameters is one of the issues of the PI controller. The modified type 2 Neuro-Fuzzy torque controller of indirect vector control-based induction motor drive is proposed in this paper by taking single input as an error i.e. speed and torque against two inputs error and change in error of conventional T2NFC.The superiority of fuzzy and neural networks has been utilized by T2NFC as type 2 MF’s consist of fuzzy and FOU. The intersection point of the membership function is smaller so that the value of the centroid method is more precise than the T1NFC. The induction motor parameters, such as stator phase current, speed, and torque of the proposed T2NFC are simulated in MATLAB at different operating conditions and compared with PI, T1NFC controllers. The proposed T2NFC significantly minimizes the ripples in torque of the induction motor in comparison with PI and T1NF controllers. The practical implementation is also carried out with a 3.7 KW induction motor using DSP 2812 controller to analyse induction motor parameters in real-time.

Published: April 2021

Human involvement in the assembly part manufacturing process is still relatively high. However, automation solutions are not flexible enough to be applied to manufacturing systems. It is essential to evaluate each work activity so that automation can be implemented effectively. We developed an automatic vision inspection using machine vision. The level of automation (LoA) in the company increases, and the impact caused by process failures on manual systems can be eliminated during inspection activities. The automation level increase in the inspection area is described and analyzed using the Hierarchy Task Analysis (HTA). Inspection data process activity and quality data are collected to determine the CCD camera selection, lamp selection, and lens selection. Three quality objectives, such as geometric quality, surface quality, and structural quality, are identified automatically using machine vision. Furthermore, after applying machine vision, an analysis of current LoA conditions and future LoA conditions is carried out. The results showed that the application of machine vision could increase the Level of Automation in the product inspection activity by 81.8%. There is a strong correlation (R = 0.924) between manual measurements carried out by operators and machine vision.
A New Adaptive Underfrequency Load Shedding Scheme to Improve Frequency Stability in Electric Power System
Authors: Boussadia Fethi , Belkhiat Saad
Published: April 2021

This paper proposes a new adaptive underfrequency load shedding scheme (UFLS) to avoid frequency instability in electrical power system during abnormal wide area disturbances. The developed scheme is based on online monitoring of the distance relay zone 3 decisions of some tie lines using (WAMS) and SCADA/EMS systems, to check rapidly and reliably the uncontrolled islanding conditions and, permit an automatic load shedding action to maintain frequency stability of power system. Simulation results on 400 kV Turkish transmission systems demonstrated the effectiveness of the proposed scheme compared to current frequency load shedding schemes which they cannot consider all possible circumstances because of their limited access to the power network data. Simulation results clearly indicate that large disturbances in power systems can be avoided and their propagation can also be stopped using the proposed scheme.

Published: April 2021

Indonesia's economic growth, which has developed in the last few decades, has contributed to an increase in the automotive industry sector. The automotive industry continues to increase the competitiveness of the automotive industry. The Lean, Agile, Resilient, Green (LARG) approach that has been applied by several global automotive industries, is able to increase competitiveness and performance in a sustainable manner. The purpose of this study is to analyze the implementation of the LARG approach in Indonesian automotive, as one of the bases for the automotive industry in Asia. The LARG value index is conducted to determine the level of application in the automotive industry in Indonesia. The mapping of the level of importance and performance of each of the LARG sub indicators was carried out using the Importance Performance Analysis (IPA) method. The results of this study confirm that there are several LARG sub indicators that have not been implemented properly. Green has the most sub-indicators that need to be improved, namely PG1 (ISO 14000 and OHSAS Certificates), PG2 (Collaboration with suppliers and customers in protecting the environment), PG6 (Carrying out industrial waste recycling), and PG8 (Product design that can reduce consumption of energy and raw materials). The calculation of the LARG implementation index value is 4.41.
Feedforward Neural Network-DTC of Multi-phase Permanent Magnet Synchronous Motor Using Five-Phase Neural Space Vector Pulse Width Modulation Strategy
Authors: Mehedi Fayçal , Benbouhenni Habib , Nezli Lazhari , Boudana Djamel
Published: April 2021

In this work, the direct torque control (DTC) is applied to the five-phase permanent magnet synchronous motor (FP-PMSM). The DTC method based on classical space vector pulse width modulation (SVPWM) is a common solution used to overcome traditional problems; such as stator flux ripple, electromagnetic torque ripple and gives more total harmonic distortion (THD) of the stator current. The actual paper is based on improving the performance of DTC-SVPWM by using the feedforward neural networks (FNNs) instead of the proportional-integral (PI) regulators and hysteresis comparators (HCs) of the conventional SVPWM strategy. This algorithm can solve the traditional PI regulators and HCs problems which are represented in responses dynamic and reduce the torque ripple, flux ripple, and the THD of stator current of FP-PMSM drives. The proposed strategy was tested in different tests with simulation using Matlab software.
Modeling and Simulation Based Analysis of the Matter Flow During Friction Stir Welding Process
Authors: Harchouche Zine El Abidine , Lousdad Abdelkader , Zemri Mothtar , Dellal Nabila , Khelil Foudil
Published: April 2021

Friction Stir Welding (FSW) is a recent assembly process which has been developed at the British Welding Institute (TWI) at the beginning of the 90's. This welding process has gone a rapid development and an increasing success. Many remarkable industrial applications achieved mainly in spatial, aeronautical, automobile, railways, marine and naval industries.... The translation and the rotation of the tool during the FSW process generate the flow and plastic deformation of the material which had been often differently interpreted in contradictory manner. In this paper, an analytical model is proposed to describe the flow of matter in the vicinity of the FSW tool pin during the welding process. Analytical solutions are elaborated on the basis of conventional fluid mechanics theory which is used to solve the associated equation to the mentioned problem based on the Laurent's series (called also Laurent's development). The knowledge of the material flow around the tool pin can lead to a better understanding of the metallurgical phenomena which have a significant effect on the mechanical properties of the welded joint and allows a better description of the speed fields which is worth full for the thermal modelisation since the great part of the thermal power is generated by auto-heating energy. The results obtained on the effect of the speeds on the material flow are in good accordance with the experimental results found in the literature. The study highlights and gives a better understanding of the material flow phenomenon during the Friction Stir Welding process.

Published: April 2021

Smart Home technology development is directly proportional to the emergence of various applications as access media. Currently, many Smart Home applications do not use the concept of human-machine interaction (HMI). The problem that often arises in the interaction between humans and machines is that humans must understand what the machine wants to have wrong perceptions about the system. In this study, the solution is proposed with the HMI concept, which uses natural language interaction through the chatbot application as an interactive medium to control and monitor Smart Home devices. In this study, the chatbot application implements the Natural Language Processing (NLP) text recognition process. User acceptance of the system is carried out using the evaluation stage. Thirty users participated in an in-depth usage study in which they tackled using the system. This research aims to create an application that can make it easier for users to control various devices on a Smart Home through natural language interaction and to analyze the performance of the NLP method. The results showed that most users (90%) believed that the application can help users control and monitor Smart Home devices. The NLP application on the chatbot application provides a success rate of 93.3% where the results obtained from the chatbot response depend on the completeness of the token.

Published: April 2021

Cinnamon wood has chemical and physical properties that can be optimized for use other than firewood. Lignocellulose compounds and a high density of raw materials would produce beneficial new compounds through pyrolysis. This research aims to make liquid smoke from cinnamon using pyrolysis and identify the concentration of the chemical compounds in liquid smoke and the rate of formation of the main compounds of liquid smoke. The Pyrolysis process was done twice, and the results were observed every 30 minutes. Chemical compounds of liquid smoke were analyzed using Gas Chromatography-Mass Spectroscopy (GC-MS). The crystal structure of charcoal produced from pyrolysis was analyzed using an X-ray diffractometer (XRD). The results showed that the liquid smoke, tar, charcoal, and the content lost after 150-minutes of pyrolysis was 28.94; 3.6; 42.92, and 24.54 %, respectively. Chromatography yielded ten peaks corresponding to compounds present in each stage of the process after 30 mins of pyrosis up to 150 mins. GC-MS analysis showed five chemical compounds, methanol, acetic acid, furfural, phenol, and guaiacol, as always present during the pyrolysis processes. Methanol, acetic acid, and phenol reached their highest concentration at the end of pyrolysis. The rate of formation of these compounds, particularly the methanol, continuously increased during the pyrolysis process. The length of the pyrolysis was proportional to the speed of methanol formation and the total yield.
Multi-Stage Statistical Approach to Wind Power Forecast Errors Evaluation: A Southern Sulawesi Case Study
Authors: Barus Dhany Harmeidy , Dalimi Rinaldy
Published: April 2021

Wind Power Plant (WPP) is part of renewable energy sources, with rapid expansion worldwide. It has the advantages of clean and green energy, but its uncertainty leads to an additional grid integration cost. The uncertainty of wind power output is much dependent on the accuracy of the wind power forecast (WPF) result. Since there is no perfect wind power forecast, understanding the current system's forecast accuracy characteristics is essential in expecting typical errors faced in the future. This paper proposed a new algorithm of the statistical approach method to evaluate characteristics of wind power forecast errors (WPFE) from an observed power system with high-penetration WPP. This method combined the approach of scatter diagram, statistical distribution, standard error performance, and score weighting in a multi-stage algorithm. It consists of serial and parallel processes to check the consistency of the results. In this study, a comprehensive analysis was made of various scenarios based on location and timescale. This proposed algorithm has been successfully tested on statistical data of Sidrap WPP and Jeneponto WPP in the Southern Sulawesi power system. The result showed that the scenario with the aggregation of both WPPs in hour-ahead timescale has the most accurate and consistent performance among all scenarios. It demonstrated specific characteristics of WPFE in the observed power system that can be used as an essential starting point in conducting future wind integration expansion studies.

Published: April 2021

The purpose of this study is to develop an accurate risk predictive model for Chronic Myeloid Leukemia (CML) after an early diagnosis of Breast Cancer (BC). Gradient Boosting Machine (GBM) classification algorithm has been applied to the SEER breast cancer dataset for females diagnosed with BC from 2010 to 2016. A practical Swarm optimizer (PSO) was utilized to optimize the GBM algorithm's hyperparameters to find the SEER dataset's best attributes. Nine attributes were carefully selected to study the growth of CML after a lag time of 6 months following BC's diagnosis. The results revealed that the predictive model could classify patients with breast cancer only and patients with breast cancer with Leukemia by an achieved Accuracy, Sensitivity, and Speciï¬city rates of 98.5 %, 99 %, 97.85 %, respectively. To verify the performance of the proposed algorithm, the accuracy of the suggested GBM classifier model was compared with another state-of-the-art model classifiers KNN (k-Nearest Neighbor), SVM (Support Vector Machine), and RF (Random Forest), which are commonly applied algorithms in most of the existing literature. The results also proved the superior ability of the implemented GBM model Classifier in the classification of breast cancer disease and prediction of patients having Leukemia developed after having breast cancer. These results are promising as they show the integral role of the GBM classifier to classify and predict the tumor with high accuracy and efficiency, which will further help in better cancer diagnosis and treatment of the disease.

Published: April 2021

Embedded Acoustic Noise Cancellation (ANC) has enjoyed remarkable success in the telecommunication field, and it becomes an essential component in various communications applications, such as digital transmission. So, it is an efficient method used to enhance the quality of communications against noise phenomena which is a problem in communication systems. This paper contributes towards a new non-linear embedded ANC based Artificial Neural Network (ANN) in digital signal processing and backpropagation (BP) of the gradient algorithm. This system is usually required for non-linear adaptive processing digital signals. The neuronal ANC estimates the noise path and subtracting noise from a received signal by minimizing a cost function. It is the mean square error. Thus, also the filter weights are adaptively updated. In this work, we designed and simulated our intelligent embedded ANC model with the help of MATLAB\Simulink software. The proposed system was designed by using embedded functions in Simulink. In addition, all simulation results are performed and verified using Signal Noise to Ratio (SNR) and Mean Square Error (MSE), number of iteration, neuronal architecture, criteria and it has been compared in various scenarios.  Finally, a study and analysis on convergence of neuronal ANC based backpropagation of the gradient algorithm demonstrate that our proposed system can effectively improve the quality of voice communications against the undesired noise. It also provides faster convergence during the back propagation of the gradient. Furthermore, the best values of SNR and MSE show the effectiveness of the proposed model.
