Multi-attribute optimization of EDM process parameters for machining of SiC and B4C particle reinforced Al 6061 metal matrix composite adopting topsis method

The tendencies of using composite materials are increasing rapidly in advanced engineering and technology applications. Ceramic reinforced aluminum composites are difficult to machine by conventional machining processes. In this work, ceramic reinforced aluminum composites are machined by Electric Discharge Machine (EDM). The goal of this study is to focus on the influence of EDM settings on Al6061 Metal Matrix Composite (MMC) reinforced with Silicon Carbide (SiC) and Boron Carbide (B4C) particles. The MMC is prepared by stirring casting route, then the workpiece is mounted on the electric discharge machine to perform the machining. Because MMC contains high abrasive ceramic (SiC and B4C) particles that are difficult to machine using traditional machining methods, an electrical discharge machine is used for machining. The experiments were conducted with four process parameters like Pulse current (I), Pulse off Time (P-Off), Pulse on Time (P-On), and Tool Lift (TL) with three levels in each parameter to examine the response measures such as Material Removal Rate (MRR), Surface Roughness (SR), Tool Wear Rate (TWR) and Surface Crack Density (SCD). The experimental results reveal that the surface crack density, MRR, SR, and TWR increases with an increase in current and pulse in time. The optimal combinations of process parameters were identified. Obtained optimal machining conditions are I input level at 9 Amps, P-On input level at 20 μs, P-Off input level at 50 μs, and Tool Lift input level at 4.5 μs with results of 0.103g/min MRR, 0.022 g/min TWR, 4. 108μm SR and 0.0048 μm SCD.
Short Communication: In vitro antimicrobial and antimalarial screening of a crude extract of Streptomyces sp. AB8 isolated from Lapindo Mud Volcano Area, Sidoarjo, Indonesia

Arifiyanto A, Setyaningrum E, Nukmal N, Aeny TN. 2021. Short Communication: In vitro antimicrobial and antimalarial screening of a crude extract of Streptomyces sp. AB8 isolated from Lapindo Mud Volcano Area, Sidoarjo, Indonesia. Biodiversitas 22: 2817-2823. Streptomyces is a potential bacterial genus that has been investigated extensively as a source of natural microbial compounds. Its potential metabolites have been widely developed for pharmaceutical, pathogen control, and other applications in agriculture. This study aimed to determine the ability of the Streptomyces sp AB8 crude extract in inhibiting Plasmodium and pathogenic microbes. Streptomyces was cultured on Gause synthetic media for 10 days. The fermented broth culture media has dissolved in a 1:1 mixture of ethyl acetate and methanol. Biochemical characterization of this isolate has carried out using the standard methods. In-vitro antimalarial activity assay was performed using a chloroquine-sensitive Plasmodium falciparum strain 3D7. Fresh type O-positive human erythrocytes were suspended at 4 percent hematocrit in a complete medium to maintain culture. The inhibitory concentration (IC50) was determined using probit analysis. The results showed the extract of Streptomyces sp. AB8 contains phenolic and alkaloids. Streptomyces sp. AB8 extract can inhibit Dickeya zeae N-Unila 5, Dickeya zeae N-Unila 10, Aspergillus sp IK3, and Escherichia coli growth. The results also showed that the ICs0 value of extract against P. falciparum 3D7 was 17.56 ug/mL. Further research was needed to determine the types of purified bioactive compounds and their bioactivity.
Wearing Out the Watchdog: The Impact of SEC Case Backlog on the Formal Investigation Process

We examine a comprehensive set of investigations by the SEC’s Division of Enforcement offices to provide evidence on the consequences of these office’s busyness on the formal investigation process. We find that higher office case backlog decreases the likelihood of an investigation into a restating firm. Our results show no evidence that higher backlogs affect the SEC’s ability to pursue cases involving revenue recognition issues and high insider trading, which is consistent with the agency’s stated priorities. But our findings indicate that busy SEC offices are less likely to pursue cases with the largest shareholder losses, which is inconsistent with SEC priorities. Backlog also impacts pursued investigations, leading to more prolonged investigations, a lower Accounting and Auditing Enforcement Releases likelihood, and smaller SEC penalties. Our evidence suggests that busyness undermines the SEC’s investigation process. JEL Classifications: G18; G38; K42; M41.
The Language Teacher Identity Construction: A Case Study Involving TEFL Undergraduate Students

Becoming a teacher is a process that underlies different aspects and purposes of social interaction, and the construction of a professional identity. Student-teachers’ perception of themselves and their emotional states might differ from their own goals or even from what is expected from them. Therefore, this research attempted to investigate the development of teacher identity construction in Teaching English as a Foreign Language (TEFL) students through their own perception of their professional identity. It was conducted as a case study – and the participants were undergraduate students in their last term. An open-ended questionnaire was used to collect data. Practical activities related to teaching and contact with teaching contexts and with students had a positive evaluation on the part of student-teachers regarding the construction of their identity as teachers. This research demonstrates the importance of the practice in the context of teacher training for the establishment and maturation of teacher identity.
Asynchronous domain decomposition methods for nonlinear PDEs

One-and two-level parallel asynchronous methods for the numerical solution of nonlinear systems of equations, especially those arising from (nonlinear) partial differential equations, are studied. The proposed methods are based on domain decomposition techniques. Local convergence theorems are presented in several cases, with appropriate hypotheses. Computational results on a shared memory multiprocessor machine for various problems exhibiting nonlinearities are reported, illustrating the potential of these asynchronous methods, especially for heterogeneous clusters.
Protective Effects of Safranal Against Selenite-Induced Cataract in Rats

Ministry of Health and Environment, Iraq. ** Department of Pharmacology and Toxicology, College of Pharmacy, University of Baghdad, Baghdad, Iraq. Abstract Cataract, which is the opacity inside clear ocular lens of eye, result in the scattering of visible light as it passes via the lens and consequently deterioration in optical image. The aim of the present study was to investigate whether safranal, an active constituent of Crocus sativus L. stigmas, has a protective effect on the cataract in the rat's pups. The animals were randomly divided into five groups, each of which consisted of 7 rat pups. Group I served as normal control (vehicle administration). For testing cataract induction, animals of Groups II, III, and IV were administered a single subcutaneous injection of sodium selenite on postpartum day 12. After sodium selenite intoxication, Group II served as control selenite, Groups III-IV received intraperitoneal safranal at doses of 200, and 300 mg/kg, respectively from the 11th day through the 17th day, while group V receive only safranal (300 mg/kg). On postpartum day 30, the rat pups were examined for cataract formation, and the lenses were isolated for further analysis. This study found that selenite caused significant (p < 0.05) cataract formation. Through the effects of selenite on the level of lipid peroxidation (MDA) which was upregulated. Furthermore, the antioxidant enzymes levels GSH levels and Nuclear factor erythroid 2-related factor 2 (NRF2) protein were downregulated. In contrast, treatment with safranal could significantly (p < 0.05) ameliorate cataract formation and oxidative damage in the lens. Moreover, safranl administration significantly increased the protein expressions of NRF2 and the GSH level, in addition to reducing the level both the MDA and the level soluble proteins in the lens. Taken together, safranal is a prospective anti-cataract agent that probably delays the onset and progression of cataracts induced by sodium selenite.
Oak leaf (Quercus spp.) intoxication in a sheep

A twenty-year-old ewe presented with acute lateral decubitus, tremor and dyspnea, followed by death. Post-mortem examination revealed a large amount of oak leaves in the rumen, reticulum and omasum. The duodenum had a focal hemorrhagic content and multifocal hemorrhages were present in several organs. Histopathological examination of the kidneys showed characteristic lesions of oak intoxication, such as intratubular hemorrhage, tubular degeneration and necrosis. This case report illustrates the importance to include oak intoxication in the differential diagnosis of acute death in sheep and the value of post-mortem and histopathological examination.
Management and outcomes of carcinoma stomach in Central India: a prospective cross-sectional study

Adenocarcinoma of the stomach was the leading cause of cancer-related death worldwide through most of the 20th century. Cancer rates in India are rising with increasing migration of rural population to the cities, increase in life expectancy and changes in lifestyles. Diet in India encompasses diversity unknown to most other countries where very little is known about the role of the Indian diet in causation or its role in prevention of cancer. Although the incidence of gastric cancer has decreased, the number of newly diagnosed cases of proximal gastric and esophago-gastric junction adenocarcinomas has increased markedly. These tumors are thought to be more aggressive than distal tumors and complex to treat. The only proven, potentially curative treatment for gastric cancer is surgical resection of all gross and microscopic disease. Even after that, disease recurs in both regional and/or distant sites in ABSTRACT

Use your smartphone to scan this QR code and download this article ABSTRACT This study applies the scale of Ricardo & Jolly in 1997 to measure the impact of corporate culture on the employee's commitment at Saigon Thuong Tin Commercial Joint Stock Bank in An Giang Branch (Sacombank An Giang). The study utilises Cronbach's Alpha reliability test method, Exploratory factor analysis (EFA), and Linear regression to verify and evaluate the scale. The adjustment coefficient R2 = 0.391 means that 39.1% of the variation of the employee's commitment dependent variable is explained by 8 independent variables in the regression model. Besides, 60.9% of employee commitment variation is explained by other factors that have not been included in the research model. The results show that the elements of banking communication (Beta = 0.283), teamwork (Beta = 0.260), risk taking in innovation and innovation (Beta = 0.176), fairness and consistency in governance policy (Beta = 0.163), rewards and recognition (Beta = 0.159) and training and development (Beta = 0.146) affect the commitment of employees at Sacombank in An Giang. The research results will be the basis for Sacombank An Giang to recognize the factors that affect employees' commitment to the bank, enabling the bank to plan to improve employee cohesion with the bank and develop a team of professional personnel. At the same time, the study proposes advanced governance implications of elements of corporate culture to employee's commitment in Sacombank An Giang. Building a truly strong corporate culture, enhancing employee commitment and sustainable development at Sacombank An Giang Branch is the core statement of this financial institution.1–27

Islamic Religious Coping, Partner Support and Parenting Stress On Mothers Who Accompany Their Children Study From Home in a Covid-19 Pandemic Situation

One of the impacts of the COVID-19 pandemic on the education and family sector is that children are required to study from home (SFH) or online. This condition makes the burden of a mother's responsibility increase because she has to be both a mother and a teacher for her children, where these demands cause mothers to experience parenting stress. This study aims to determine how big the contribution of Islamic religious coping variables and partner support to parenting stress. This study used quantitative research methods with a three-variable correlation research design. The research respondents were 319 mothers in Indonesia with an age range between 26 and 51 years old. The measuring instrument used is Islamic religious coping short-form (IRCS) Raiya (2008), Receipt of Spousal Support Scale (RSSS) from Dorio (2010), and the Parenting Stress Scale (PSS) from Berry and Jones (1995). The research data were analyzed using the SPSS 26 statistical analysis program with multiple linear regression test techniques to answer the research hypothesis. The results showed that there was a significant negative contribution of Islamic religious coping and partner support to parenting stress for mothers who accompanied SFH children in the COVID-19 pandemic situation.
Multimodal disinformation about otherness on the internet . The spread of racist, xenophobic and Islamophobic fake news in 2020*

This work studies the use of disinformation to construct an image of otherness through the internet. We applied a content analysis methodology to the 161 racist, xenophobic or Islamophobic fake news pieces that were discredited in 2020 by the four Spanish information verification media entities accredited by the International Fact-Checking Network: Maldita.es , Newtral , Efe Verifica and Verificat . The results show that the most commonly used formats were image and video, that disinformation was most often based on taking information out of context and deception
Scaling Blockchains: Can Elected Committees Help?

In the high-stakes race to develop more scalable blockchains, some platforms (Cosmos, EOS, TRON, etc.) have adopted committee-based consensus protocols, whereby the blockchain's record-keeping rights are entrusted to a committee of elected block producers. In theory, the smaller the committee, the faster the blockchain can reach consensus and the more it can scale. What's less clear, is whether this mechanism ensures that honest committees can be consistently elected, given voters typically have limited information. Using EOS' Delegated Proof of Stake (DPoS) protocol as a backdrop, we show that identifying the optimal voting strategy is complex and practically out of reach. We empirically characterize some simpler (suboptimal) voting strategies that token holders resort to in practice and show that these nonetheless converge to optimality, exponentially quickly. This yields efficiency gains over other PoS protocols that rely on randomized block producer selection. Our results suggest that (elected) committee-based consensus, as implemented in DPoS, can be robust and efficient, despite its complexity.
Investigating Perceptions and Skills of Gifted Students in STEM Education

Science, Technology, Engineering and Mathematics (STEM) provides a noteworthy conceptual lens for many countries when it comes to labor recruitment. For many countries, providing opportunities for gifted students at school and quality STEM education should be included. A limited number of qualitative study has focused in-depth on the skills and perceptions of gifted students in STEM education. Therefore, this article aims to explore gifted students' perceptions and skills by applying STEM education. The study was conducted with 17 middle school gifted students. It includes data collection, a series of interviews, student diaries focusing on the STEM experiences of gifted children, and a self-assessment form that allows students to evaluate themselves in activities. As a result, it was concluded that STEM education practices are important in discovering the perceptions and skills of gifted students, and that students improve their scientific inquiry, argumentation, technological inquiry, and creative thinking skills, and enable career choice to them. In addition, it seems that STEM activities need more work with gifted students.

How Important Are Semi-Annual Earnings Announcements? An Information Event Perspective

Using a method that avoids the need to specify earnings expectations (Ball and Shivakumar 2008), we demonstrate that the period surrounding the semi-annual announcement of Australian firms’ earnings is, on average, an important source of information. Although there is substantial year-to-year variation, we observe no evidence of any significant time trend, and also conclude that a shift from Australian domestic GAAP to IFRS did not impact the association between earnings announcement windows and stock returns. We also find no evidence that the informativeness of earnings announcements varies systematically with firm size, analyst following or economic news (i.e., positive versus negative stock returns, profits versus losses), although we do observe significant variation across industries. Our conclusion is further supported by contrasting the earnings release date with the days immediately prior to release, or high information days other than earnings announcement windows. Using a more precise event window relative to prior studies (i.e., three hours versus three days), we confirm that earnings announcements contain significant new information about fundamentals.
CALCULATING MODELS FOR TOTAL FACTOR PRODUCTIVITY MEASUREMENT MODELOS DE CÁLCULO PARA A PRODUTIVIDADE TOTAL DOS FATORES

Productivity measures the level of efficiency a particular economy presents in producing goods and services. Thus, increasing productivity is the fastest route to achieve economic growth and social well-being. This article aims to estimate and compare four Total Factor Productivity (TFP) measurement models. The models chosen were: Olley & Pakes OP (1996); Levinsohn & Petrin – LP (2003); Wooldridge Wool (2009); and Ackerberg, Caves & Frazer ACF (2015). Per capita energy consumption was employed as the intermediate input. The results suggest that the ACF (2015) model is an improvement form the OP and LP models, while presenting statistically significant results. The Wool (2009) model is also an improvement and, once more, presented similar results. Considering the ACF model presents high dispersion, the Wool model is the preferred TFP measurement model.
Image Analysis for MRI-Based Brain Tumor Classification Using Deep Learning

Tumors are cells that grow abnormally and uncontrollably, whereas brain tumors are abnormally growing cells growing in or near the brain. It is estimated that 23,890 adults (13,590 males and 10,300 females) in the United States and 3,540 children under the age of 15 would be diagnosed with a brain tumor. Meanwhile, there are over 250 cases in Indonesia of patients afflicted with brain tumors, both adults and infants. The doctor or medical personnel usually conducted a radiological test that commonly performed using magnetic resonance image (MRI) to identify the brain tumor. From several studies, each researcher claims that the results of their proposed method can detect brain tumors with high accuracy; however, there are still flaws in their methods. This paper will discuss the classification of MRI-based brain tumors using deep learning and transfer learning. Transfer learning allows for various domains, functions, and distributions used in training and research. This research used a public dataset. The dataset comprises 253 images, divided into 98 tumor-free brain images and 155 tumor images. Residual Network (ResNet), Neural Architecture Search Network (NASNet), Xception, DenseNet, and Visual Geometry Group (VGG) are the techniques that will use in this paper. The results got to show that the ResNet50 model gets 96% for the accuracy, and VGG16 gets 96% for the accuracy. The results obtained indicate that transfer learning can handle medical images.

Relationship between second toe length and androgen-linked behaviours among students of Delta State University, Abraka, Nigeria

Background: During the formation of the limbs, a simultaneous production of androgens occurs. It has also been noticed that when genetic process is inhibited, it can lead to complications affecting the limbs. It is therefore believed that testosterone influences the development of the limbs. Aim: This study therefore looked at the association between second toe length and androgen linked behaviours. Materials and Method: Three hundred (166 males and 134 females) subjects who were students of Basic Medical Sciences, Delta State University, Abraka aged 18 and above, were selected using the cross-sectional descriptive study design. Second toe length was observed, standardize questionnaire on handedness, competition and aggregation was administered to students. Data obtained were analyzed with Statistical Package for Social Sciences. Results: This study established a significant association between 2nd toe length and some androgen linked behaviours. Significant association between subjects with longer 2nd toe and competitiveness was observed (p<0.05) as well as aggressive behavior. Conclusion: From this study, it was deduced that androgens influence 2nd toe length and 2nd toe length also influences androgen linked behaviours such as competition and aggression.
