Authors: Rojas Jhan Prieo , García Gonzalo Romero , Castillo Dora Villada
Published: January 2022

This article presents a comparison of energy generation using two methods of power production for different geographical locations. For this comparison, the HOMER software was used, which allows simulating generation systems with different energy sources. For the development of these simulations it was necessary to collect three parameters in the locations to be analyzed, which were wind speed, solar radiation and temperature. The photovoltaic array system was simulated using from 10 to 200 units with a constant value of one wind turbine, while for the wind turbine system, 1 to 9 units were used together with a constant value of 100 photovoltaic arrays. For the photovoltaic system, there is no major difference in the net project cost, the renewable fraction and the annual carbon dioxide production when using a greater number of arrays, but an increase in energy production is observed, a greater effect is obtained by changing the location of the system, analyzing the wind system a greater number of turbines increases the energy production, but also increase the annual carbon dioxide production and project cost, there is no significant difference between locations for the project cost the other parameters are affected. By using an optimization algorithm in the systems, the best performance was obtained in Puerto Bolivar using 105 photovoltaic arrays of 1kW and 3 wind turbines of 1.5MW.

Population growth, urbanization, and infrastructure development activities have resulted in the land conversion of forests and farmlands to residential and commercial zones. Such land conversion causes changes in the land cover, as experienced in the Ayung Watershed, in the island of Bali, Indonesia. Here, the land cover undergoes rapid changes due to the growing tourism sector, affecting the runoff coefficient. This study evaluated the changing land cover patterns and surface runoff in the Ayung Watershed between 2012 and 2019. An increase in the surface runoff during the high rainfall events may lead to flooding in the area. The identification of land change patterns in the Ayung Watershed was carried out by a manual digitizing process on Google Earth maps. The runoff coefficient was calculated by Cook’s method using the four physical characteristics of the watershed: land cover, infiltration rate, land slope and drainage density; showing significant changes in the land cover in the study area. Farmlands and forests were reduced by 647.8 ha and 553.1 ha respectively, converted into fast growing grasslands or unproductive land. Such land cover changes have a negative impact by increasing the runoff coefficient in the area. During the study period, the runoff coefficient was consistently found to be more than 0.6 (high-risk category). Several sections in the city of Denpasar experienced an increase in the runoff coefficient by more than 5%. Consequently, there was a high-risk of flooding in the area because of the increasing surface runoff.

Background: Recently, researchers have considered extremely low-frequency electromagnetic fields (ELF-EMFs), as one of the non-invasive therapies, in the treatment of many severe neurological disorders, including Alzheimer Disease (AD). AD is a progressive neurodegenerative disease characterized by the deposition of amyloid plaques in the brain. However, the increase in microglial cells increases phagocytosis and the destruction of amyloid plaques. Therefore, the present study aimed to investigate the amount of β-amyloid precursor deposition and the number of microglia cells in the animal model of AD before and after exposure to ELF-EMFs. Objective: The aim of this study was to investigate the deposition of beta ameloid precursor and the number of microglial cells in the Alzheimer's animal model before and after exposure to magnetic waves. Methods: Fifty male adult rats were randomly grouped into 5: The control group, the ELF-EMFs group, the AD group, the treatment group 1, and the treatment group 2. After the study period, the animals were killed for immunohistochemistry assessment to detect and compare the deposition of β-amyloid and the production of allograft inflammatory factor 1 (Iba1) protein. Results: Exposure to ELF reduced the deposition of β-amyloid and increased microglia cells. However, these changes were not different between the control and ELF-EMFs groups (P<0.001). Conclusion: ELF-EMF can reduce the formation of β-amyloid plaques and induce the proliferation of microglia cells. Therefore, they can be used to treat brain damage caused by Alzheimer disease.

Authors: Lee Han-Sol , Moseykin Yury N. , Chernikov Sergey U.
Published: January 2022

This paper empirically analyzes sustainable relations between inward FDI (IFDI), outward FDI (OFDI), the R&D expenditure ratio and CO2 emissions based on balanced panel data from the BRICS (namely, Brazil, Russia, India, China and South Africa) countries for the period 2003–2017. Generally, the results confirm a negative effect of IFDI and a positive effect of OFDI on the R&D expenditure ratio, both with statistical significance. Further exploration of the IFDI, OFDI and R&D impacts on CO2 emissions was based on an assumption that innovation development mitigates environmental pollution. The research outcome revealed positive associations between IFDI and the R&D expenditure ratio with CO2 emissions, showing the connection of environmental pollution to growth-focused national economic strategies. Based on these results, we recommend the following policies: (1) rethinking domestic industries protectionism trends and research support to enhance FDI spillover effects, (2) the drafting of New Development Bank specific environment-friendly investment programs aimed at innovation activities, and (3) looking into further easing the green technologies from developed countries.

Potensi Pemanfaatan Gas Karbon Dioksida (CO2) sebagai Density Agent untuk Larutan Pemisah Cangkang dan Kernel Sawit
Authors: Muhammad Muhammad , Marwan Marwan , Zaki Muhammad , Munawar Edi
Published: January 2022

In order to achieve the national target of decarbonization by 2030, Palm oil mills (POM) can contribute to reducing CO2 emissions generated from their production activities. The CO2 emitted from POM is currently discharged into the environment without further treatment. As a result, the amount of CO2 in the atmosphere will rise, increasing global warming. This study proposes an approach of utilizing CO2 as a density agent in separation fluid formulation. The formulated fluid is then used to separate palm shells and kernels in the claybath. The solubility of CO2 in water occurs physically and is dependent on temperature and partial CO2 gas in the air. Monoethanolamine (MEA) was used as an absorbent to ensure the full interaction of CO2 with water. The chemisorption method is selected to dissolution CO2 into aqueous MEA. The mass ratios of MEA were varied by 10, 20, 30, 40, 50 % w/w. The achieved appropriate densities of formulated fluid were 1,11, 1,14, dan 1,17 g/cm3 at mass ratios of MEA:H2O is 30, 40, dan 50% w/w, respectively. All achieved densities fall between palm shells and kernels densities. Furthermore, the formulated fluid can be used as separation fluid in claybath for separating palm shells and kernels. In addition to the proposed idea of utilizing CO2  and, at the same time, reducing CO2 emission from POM.

Published: January 2022

PT. Pertamina Fuel Terminal Meulaboh is a business unit of PT. Pertamina (Persero) under the function of Supply Distribution has the main task of carrying out the activities of receiving, stockpiling, and distributing fuel oil. In the distribution and operation processes carried out, 8 risks may occur. Based on the Gray FMEA method, the priority risk that occurs is the delay of the tanker which has the smallest gray relationship, which is 0.435 and the risk of the interconnection of information system support between functions which is still problematic is 0.452. Through the Root Cause Analysis method approach, the root causes of the risk of ship delays are non-routine maintenance/maintenance on ship engines, lack of training for crew members according to function, and bad weather conditions. Meanwhile, the risk of the interconnection of information systems support between functions is still problematic due to the lack of maintenance and network management. The alternative strategy for improvement that can be done by the company is to work with the BMKG to help predict the weather, improve the quality of workers according to their functions, provide adequate equipment and reliable mechanics to carry out SOPs for maintaining ship engines properly and cooperate with service management companies to assist companies in managing and maintaining networks.

O direito e status jurídico dos animais não-humanos
Authors: Moraes Marianna Machado
Published: January 2022

Este artigo aborda os direitos fundamentais dos animais não-humanos, contrapondo o movimento da ética animal ao avanço legislativo. A questão que norteou a pesquisa foi: o avanço da legislação protetiva aos animais sencientes tem sido suficiente para proteger os animais não-humanos no Brasil? Com vistas a responder o problema proposto, o presente artigo objetiva discutir o avanço da legislação protetiva aos animais sencientes em uma perspectiva política, jurídica e ética. A metodologia empregada no desenvolvimento desta pesquisa foi a pesquisa bibliográfica, realizada a partir da consulta a livros, artigos, jurisprudência e legislações que se dedicam ao estudo dos direitos dos animais não-humanos. Foi visto que no Brasil, a questão das vaquejadas, bem como muitos outros atos de maus-tratos aos animais, não deixa dúvida de que no estágio em que a legislação brasileira se encontra atualmente, os animais não têm recebido uma proteção efetiva. Já a Legislação Portuguesa, parece ser mais efetiva que a brasileira. Trata-se de um estatuto jurídico que deixou de tratar os animais como objetos para considerá-los seres dotados de sensações e sentimentos. Ao final do estudo concluiu-se que a Legislação Portuguesa poderia servir para inspirar o legislativo brasileiro a respeitar mais os animais e para motivar o parlamento a dar celeridade aos projetos de lei sobre a matéria.
INFORMATION SECURITY UPGRADE ACCORDING TO ARTIFICIAL INTELLIGENCE TECHNOLOGIES
Authors:   Interregional Academy of Personnel Management, Lysenko Serhii
Published: January 2022

The article is devoted to the problems of the growing role of artificial intelligence technologies and the need for legal regulation of the processes of interaction between artificial intelligence and humans, in the context of information security. According to the author, without a full and timely regulatory regulation of the development of technological innovations that can make independent decisions, society runs the risk of suffering serious losses. Therefore, it is extremely important already now, to develop and implement for information technologies such administrative and legal regulation, in which the development of technologies will not lead to risks for society and will retain control over what is happening to the person. The author suggests that in future artificial intelligence is deprived of the status of a computer program or technology, and it will become an independent subject of law, citing as an example of acquiring legal capacity by another artificial, abstract entity � the state. In the publication examines the existing attempts to form a legal framework for interaction between humans and artificial intelligence, which took place in the European Union, Japan and the PRC. This includes the precedent for recognizing artificial intelligence as an independent creative unit, which has already taken place in the Chinese city of Shenzhen, where the court ruled that some articles written using artificial intelligence are protected by copyright. Special attention is devoted to the analysis of domestic studies of the prospects for the use of artificial intelligence and its interaction with humans. The author proposes an approach to the regulation of legal relations associated with artificial intelligence, built around the principle � technology for the benefit of a person, to respect his rights and freedoms. The author predicts a shift in priorities in the field of information security from the protection of personal data and the security of their use, to the prevention of uncontrolled use of artificial intelligence, in the areas related to the implementation of human rights and freedoms.
CENTRAL BANKS' RESPONSE TO INFLATION, OUTPUT GAP, AND EXCHANGE RATE IN NIGERIA AND SOUTH AFRICA
Authors:   Pan Atlantic University, Vincent Olusegun
Published: January 2022

This study examines inflation targeting in Nigeria and South Africa, using fully modified least square to estimate a modified Taylor rule for the period 1970 to 2016. The study unravels evidence of a significant response of inflation and squared inflation to policy interest rates in South Africa, but not in Nigeria. Overall, South Africa�s central bank places much emphasis on inflation targeting in setting interest rates which Nigeria does not. Further, for South Africa, output gap is significant, while it is not significant for Nigeria. The study also reveals that exchange rate, openness to trade and international reserves play significant roles in central bank policy in both countries. In other words, there is need for central banks to adopt an eclectic approach, setting the monetary policy rule to adjust to any observed disequilibrium between output gap, inflation, exchange rate, foreign reserves and openness to trade. However, strict inflation targeting may not serve as an appropriate framework to address the crucial macroeconomic problems challenging these African economies. However, developing countries� central banks, such as in Nigeria and South Africa, often have weak financial, fiscal and monetary institutions, thus rendering the application of inflation targeting considerably difficult. In this regard, the degree of the triumph of inflation targeting significantly depends on executive capacity, and the political will and commitment on the part of the central banks. The central banks should therefore be flexible about inflation objectives/targets when confronted with more pressing macroeconomic problems that could be remedied using existing policy instruments. From the findings of this study, it can be seen that there is a need to adopt an eclectic approach to setting the monetary policy rule. It is important to set the interest rate to adjust to any observed disequilibrium between output gap, inflation, exchange rate, foreign reserves and openness to trade. In fact, strict inflation targeting may not be an appropriate framework to solve the key macroeconomic problems challenging these African economies, such as price instability, exchange rate stability and inclusive economic growth. Still, inflation targeting remains a relevant policy approach but may not be adequate in its capacity to deal with economic and financial crisis if deployed only.

Green Chemistry (GC) integration in environmental education has improved understanding of managing pollutants and their impacts. However, the extent of integration in the science curriculum is not widely known in the Philippines. In this convergent mixed-method design, the researchers determined the SHS Chemistry teachers’ (n=30) knowledge, perceptions, GC integration in Chemistry topics, and challenges in teaching Green Chemistry Education (GCE). Complementary quantitative and qualitative results showed valid and reliable findings, claiming that teachers have limited preconceived knowledge on GCE but perceived it as an essential part of the teaching-learning process. Awareness of chemical hazards and their impacts on the environment is often demonstrated but rarely elaborated during discussions in Chemistry classes. Problems encountered in teaching GCE were also identified. A moderate positive correlation between the teachers’ knowledge and their GC perception was observed. However, no significant relationship was found when the teachers’ knowledge and perception were correlated to GC integration.

Published: January 2022

Malaysian Private Entity Reporting Standard (MPERS) serves as a new reporting framework to private entities and significant milestones to the capital market. This enables the entities to assert the financial statements with full compliance with the International Financial Reporting Standard (IFRS). Thus, the focus of this paper is to discuss the conceptual framework on the impact of external pressure and environmental uncertainty on the quality of financial reporting by Small and Medium Enterprises (SMEs) in Malaysia. The effect of the Covid-19 pandemic on environmental uncertainty has an impact on the quality of financial reporting. It is expected that the Malaysia’s authority and regulator will anticipate the impact of the Covid-19 pandemic, given the outbreak has created disruption in all business chains including the SMEs in Malaysia.

Published: January 2022

The current study was conducted to assess the antioxidant, antimicrobial, cytotoxicity and thrombolytic potential of the leaves and stem bark of Erythrina fusca Lour grown in Bangladesh. For the assessment of antioxidant properties, DPPH scavenging and phosphomolybdenum assays were used. In the DPPH free radical scavenging assay, the chloroform soluble fraction of a methanol extract of leaves of E. fusca exhibited the highest free radical scavenging activity with an IC50 value of 5.5 ± 0.60 μg/ml, while the reference standard (ascorbic acid) showed an IC50 value of 5.8 ± 0.18 μg/ml. All the test samples and the standard BHT demonstrated good linear relationship in the phosphomolybdenum assay. It was observed that the test samples contained considerable number of bioactive compounds including total phenolics in the aqueous soluble fraction of the leaves giving the highest 94.02 ± 1.004 GAE/100g of dried sample. All test samples exhibited moderate antimicrobial activity against 13 Gram-positive and Gram-negative bacterial strains and 3 fungi, where the chloroform soluble fraction of the stem bark demonstrated the highest inhibition of growth with zone of inhibition of 19.3 ± 0.21 mm against Bacillus cereus. All the test samples displayed cytotoxic activity against brine shrimp nauplii having significant LC50 and LC90 values. The chloroform soluble materials demonstrated highest lethality with LC50 value of 1.55 ± 0.30 μg/ml and LC90 65.68 ± 0.23 μg/ml. On the other hand, the carbon tetrachloride soluble fraction of the stem bark showed the highest clot lysis (22.75 ± 0.59%) as compared to that (66.77 ± 0.61%) revealed by reference standard, streptokinase. The findings of this study revealed that the leaves and stem bark of E. fusca growing in Bangladesh possesses bioactive compounds but further studies are required to purify and identify them.

Published: January 2022

Hospital pharmacy and graduate pharmacists are part and parcel of a proper healthcare system. This study aims to assess Bangladesh's current hospital pharmacy practice and drug management system. A face-to-face interview-based survey was designed, and 15 hospitals of Khulna Division of Bangladesh were subjected to evaluation by a close-ended questionnaire containing 17 questions regarding hospital pharmacy practice and drug management system. Among 15 hospitals, 67% had hospital pharmacy services, whereas 47% had “C” grade pharmacists, and 53% of hospitals had no narcotic drug locker. Surprisingly, 87% of hospitals had no PTC (pharmacy and therapeutic committee), and 40% had no control over drug abuse. Besides, only 6.67% of hospitals had graduate pharmacists (A grade pharmacists), and 33% had no pharmacists. Furthermore, 67% of hospitals provided drug-using information, and 60% of hospitals provided no dosing information to their patients. Moreover, 40% did not maintain the record for expired products and had no “not for sale” tag for expired or damaged medicines. The current study findings suggest that the respective authorities must revisit the current healthcare system and take immediate initiatives to appoint graduate pharmacists in every hospital to improve the medical service with a proper drug management system.

Background: Coronavirus disease 2019 (COVID-19) has produced a significant health burden worldwide. Recent studies had shown that cardiac injury in COVID-19 is not uncommon and may leads to death. The aim of this study was to assess cardiac troponin in patients with COVID-19 and to evaluate the incidence of myocardial injury.

Methods: A cross-sectional study was designed among 100 hospitalized patients with moderate to severe COVID-19 in Combined Military Hospital (CMH), Dhaka from January to April, 2021, after considering inclusion and exclusion criteria, study population was divided into two groups on the basis of normal and elevated troponin level.

Results: Participants had mean age of 67.33 ± 7.63 years with 76% men. 42% population had elevation in troponin levels. Risk factors like age, Diabetes (DM), C-reactive protein (CRP), Lactate dehydrogenase (LDH), D- Dimer, Ferrtin level were more in elevated troponin group and statistically significant. Troponin levels significantly increased with increasing severity of COVID-19 staging (Kendall’s tau-b =0.479, p= 0.004) with reflected moderate positive correlation. Multivariate analysis was performed for association of COVID- 19 severity with elevated troponin separately after adjusting for other known confounding factors. Independent association between COVID-19 severity and troponin remained significant after that along with other acute phase reactants and inflammatory markers.

Conclusion: COVID-19 can significantly leads to myocardial injury. This data suggested elevated troponin level is one of the determinants of clinical outcome in patients with COVID-19.

Published: January 2022

Political science graduate students have flocked to join #AcademicTwitter in recent years. However, navigating the social media landscape can be daunting for graduate students trying to find their stride. We highlight six different approaches for Twitter among political scientists to provide graduate students a blueprint for navigating the app. Specifically, we note that Twitter can help students find research, promote their own work, ask for advice, and network among other uses. We conclude with tips on maintaining boundaries and ensuring one's safety while using the app. **NOTE: This manuscript is part of Strategies for Navigating Graduate School and Beyond, a forthcoming volume for those interested in pursuing graduate education in political science (Fall 2022 publication).
