Authors:   North-West Institute of Management of the Russian Presidential Academy of National Economy and Public Administration, Kovalev А.А.
Published: April 2021

The author analyzes the dualism of good and evil in early antique philosophy, primarily in the legacy of the Presocratics. The influence of pre-Socratic ideas about the phenomenon of evil and its dialectical relationship with the good, not just on Socrates and whole high Greek philosophical classics, but also on Stoics, is explored. Using methods of historical and philosophical analysis as well as a comparativist approach, the author concludes that good and evil as cosmogonic categories in ancient Greece and Rome acquired the features of ethical and sociopolitical categories in the high classics.

Authors:   National Research University «MIET», Rastimehina T.V.
Published: April 2021

The author examines the actions of states in crisis and emergency situations and conducts a comparative analysis of the emergency measures taken by the governments of democratic states and hybrid regime states. The author notes the Matthew eﬀect: the actions of the institutions of political power of democratic and undemocratic countries in the conditions of the regime of increased readiness at a superficial examination seem similar, but have a diﬀerent eﬀect. In democracies, the restriction of some of the freedoms of citizens fits into the general trend toward humanization of politics. At the same time, autocracies presumably use the crisis to redistribute power resources toward the executive branch and to normalize the suppression of civic engagement.

Authors:   Akademi Pengajian Bahasa, Universiti Teknologi MARA Malaysia, Ali Nurhafizah , Muslim Mazni ,   Universiti Teknologi MARA Malaysia, Mustapha Aida ,   Universiti Teknologi MARA Malaysia
Published: April 2021

The fights against sexism have been going on for decades. However, women in the present society still experience gender and social injustice, domestic violence and sexual harassment on a daily basis. In many cases, conservative families with patriarchal values become a breeding ground for unfair treatment and discrimination against women. Maniam brings up these issues to the public through his short story ‘Mala’. This study seeks to examine the male characters’ behaviour, attitude and treatment towards Malati, the main protagonist of the story – and how she deals with the treatment she receives from them. The analysis reveals that the female protagonist is suppressed by her father when she was young, emotionally abused and exploited for free labour by her husband when she is married and harassed by her male clients at her workplace. The poor treatments she has received from men around her since young leave her with the feelings of numbness and unworthiness for the rest of her life.

Authors: Ismail Normah , Sahimi Siti Noorsyarafana
Published: April 2021

The term of immobilized enzymes refers to enzymes that physically entrapped within pores of synthetic or natural polymeric network with no alteration in the enzyme catalytic activities. In this study, protease from silver catfish viscera have been extracted, partially purified by acetone precipitation method and immobilised in the calcium alginate beads. Various range of sodium alginate (1–5% w/v) and calcium chloride (0.1–0.5 M) concentrations were used for the optimization purpose. Proteolytic activity of the protease in the alginate beads was measured as a response to the independent variables by using casein as a substrate. The highest actual and predicted proteolytic activities were at run 12 with 674.77 CDU/mg and 639.26 CDU/mg, respectively, under predetermined factors, in which the sodium alginate and calcium chloride solution concentrations were at 3.00% (w/v) and 0.30 M, respectively. The lowest actual and predicted proteolytic activities were at run 2 with the values of 77.35 CDU/mg and 71.53 CDU/mg, respectively, whereby factors include were a sodium alginate of 4.00% (w/v) and 0.20 M of calcium chloride solution. For the experimental feasibilities, the optimum conditions that was feasible to be carried out was with a sodium alginate of 2.99% (w/v) and 0.30 M calcium chloride solution. Verification for the optimum condition was performed and there was no significant difference (p > 0.05) between the predicted (638.19 CDU/mg) and verified (699.82 CDU/mg) values. Thus, indicating that the model was significant and can be used to produce the immobilize protease under the optimum condition.
The Features of Translation Maximus the Greek: The Colloquies in Matthewʼs Gospel
Authors:   School No 1561, Gnevsheva Irina
Published: April 2021

This paper examines one of the important translation technique’s features in the Maximus the Greek’s book circle. It is consistently described the various ways of transferring the Greek substantive infinitive to the Church Slavonic language there. In 1524, Maximus the Greek, in collaboration with his disciple Silvan, a monk of the Trinity-Sergius Abbey, translated Homilia of John Chrysostom into the Gospel of Matthew. The analysis of the linguistic material in the Homilia showed that when translating infinitive constructions, there is a tendency to unify, and the main method of transmission into the Church Slavonic language is calcification. The Greek orientation indicates the implementation of the strategy of the early grammatical reference of Maximus the Greek in the translation, and also it allows us to state the proximity of this work to the translations of the 14th century and to establish a connection with the Chudovsky and Athos versions of the New Testament.
Modelling of Supercapacitors Based on Simplified Equivalent Circuit
Authors:   Recep Tayyip Erdoğan University, Şahin Mustafa
Published: April 2021

The need for energy storage devices especially in renewable energy applications has increased the use of supercapacitors. Accordingly, several supercapacitor models have been proposed in previous researches. Nevertheless, most of them require an intensive test to obtain the model parameters. These may not be suitable for an initial simulation study, where a simple model based on the datasheet is required to evaluate the system performance before building the hardware prototype. A simplified electrical circuit model for a supercapacitor (SC) based on the voltage-current equation is proposed in this paper to address this issue. This model doesn’t need an intensive test for accuracy. The structural simplicity and decent modelling accuracy make the equivalent electrical circuit model very suitable for power electronic applications and real-time energy management simulations. The parameters of the proposed model can be obtained from the datasheets value with a minimum test requirement. The experimental method to provide the parameters of the supercapacitor equivalent circuit is described. Based on the proposed method, the supercapacitor model is built in Matlab/Simulink, and the characteristics of equivalent series resistance (ESR) measurement and cycle life are compared with datasheets. The simulation results have verified that the proposed model can be applied to simulate the behaviour of the supercapacitor in most energy and power applications for a short time of energy storage. A supercapacitor test circuit is given to test the charge and discharge of supercapacitor modules. The experimental results are suitable for simulation results.

Published: April 2021

The influence of Toxoplasma gondii on some biochemical parameters has lately gained an increasing attention. The aim of this study was to assess the levels of some biochemical parameters in Toxoplasma positive and negative subjects. An analytical case–control study was achieved in Baghdad for the period from October 2018 until March 2019. Forty nine females participated in this study, with an age range of 18-55 years. The participants were separated into two groups, namely Toxoplasma positive subjects (n=21) and Toxoplasma negative subjects (n=28), based on enzyme-linked immunosorbent assay (ELISA). Blood and serum samples were collected from all subjects to evaluate the serum levels of cholesterol, triglycerides, high density lipoprotein (HDL), very low density lipoprotein (VLDL), low density lipoprotein (LDL), total protein, total globulin and total albumin. The results showed non-significant differences between Toxoplasma positive and negative subjects for all the parameters, although cholesterol levels were lower  (mean 149 mg/dL; range 131.9-165.9 mg/dL) in Toxoplasma positive patients as compared to those in Toxoplasma negative subjects (161 mg/dL; 146.7-175 mg/dL).  In addition, triglycerides levels were lower  (160 mg/dL; 123.3-196.8 mg/dL) in Toxoplasma positive subjects as compared to the control subjects (165mg/dL; 134.2-195.3 mg/dL). The only significant difference was noticed among subjects with an age range of 26-35 years, where globulin level was significantly higher (p=0.023)  in Toxoplasma negative subjects as compared to that in Toxoplasma positive subjects.

Authors: Nariman Nidhal Omar  , Rana Kadhim Mohammed
Published: April 2021

Three hundred and sixty different samples were collected from different sources, including wound, burn, nasal, and oral swabs from several hospitals in Baghdad. A number of 150 (53%) Staphylococcus aureus samples were isolated and identified among a total of 283 samples. Then, the spread of the Toxic Shock Syndrome Toxin-1 gene (tsst-1) was investigated in β-lactamase resistant S. aureus. According to the source of samples, the distribution of S. aureus  isolates was found to be significantly higher (p < 0.01) in wound samples as compared to other sources. According to the age, a highly significant  distribution (p < 0.01) was recorded in the age group of 15-30 years, whereas gender comparison showed no statistically significant differences. All the isolates were subjected to susceptibility test against eight β-Lactam antibiotics by using the disc diffusion method. The antimicrobial susceptibility test showed that S. aureus had maximum resistance percentage to Carbenicillin (97.3%), while the lowest resistance rate was against Meropenem, with a sensitivity rate of up to 82%. In addition, 144 (96%) out of the 150 S. aureus isolates have multiple drug resistance (MDR). All the isolates were subjected to polymerase chain reaction to amplify tsst-1 toxin gene. A number of 70 isolates (46.7%) were found to be positive for tsst-1 gene. The results showed no significant correlation between tsst-1 gene with the individual antibiotic resistance and the multi-drug resistance patterns of the isolates (p = 0.226).

Published: April 2021

Iraq territory as a whole and south of Iraq in particular encountered rapid desertification and signs of severe land degradation in the last decades. Both natural and anthropogenic factors are responsible for the extent of desertification. Remote sensing data and image analysis tools were employed to identify, detect, and monitor desertification in Basra governorate. Different remote sensing indicators and image indices were applied in order to better identify the desertification development in the study area, including the Normalized difference vegetation index (NDVI), Normalized Difference Water Index (NDWI), Salinity index (SI), Top Soil Grain Size Index (GSI) , Land Surface Temperature (LST) , Land Surface Soil Moisture (LSM), and Land Degradation Risk Index (LDI) which was used for the assessment of degradation severity .Three Landsat images, acquired in 1973, 1993, and 2013, were used to evaluate the potential of using remote sensing analysis in desertification monitoring. The approach applied in this study for evaluating this phenomenon was proven to be an effective tool for the recognition of areas at risk of desertification. The results indicated that the arid zone of Basra governorate encounters substantial changes in the environment, such as decreasing surface water, degradation of agricultural lands (as palm orchards and crops), and deterioration of marshlands. Additional changes include increased salinization with the creeping of sand dunes to agricultural areas, as well as the impacts of oil fields and other facilities.
Performance Analysis of a SWIPT Enabled UAV-Assisted Relaying
Authors: Chowdhury Imtiaz Akber
Published: April 2021

In the recent era, unmanned aerial vehicle (UAV) plays an important role in numerous application fields related to the wireless communication system. Due to its precise control, efficient deployment, and affordable cost, UAV-assisted communication attracts significant attention to all the sectors including the defense sector, agriculture sector, and security purpose, and so on. Though UAVassisted relaying has enormous advantages but there are potential challenges while UAV deploys as a relay. For example, deploying UAV in the wireless communication field, its battery life is the main concern due to its limited battery size and storage capacity. To get significant benefits from UAV while deployed in the cooperative communication network, the battery status of the UAV is an unavoidable issue. To minimize the aforementioned problem, energy harvesting (EH) techniques can be an efficient solution. The UAV can harvest energy from the transmitted power by the source and with the help of this harvested energy UAV can retransmit the signal to the destination. However, there are several parameters that also significantly influence the UAV-based cooperative system performance such as UAV’s position, time allocation factor and power allocation factor, and UAV’s height. Considering the importance of the aforementioned parameters, in this paper, we have considered simultaneous wireless information and power transfer (SWIPT) enabled UAV-assisted relaying network and evaluate the system outage performance with different parameters aspects. We have provided some insight about the parameters such as the UAV’s position, the power allocation factor and the time allocation factor and the UAV’s height by providing simulation results such as the outage probability versus transmit power in the different urban scenario, the outage probability versus time allocation factor and power allocation factor and the outage probability versus UAV’s height. These simulation results clearly show the significance of the abovementioned parameters in wireless-powered UAVassisted cooperative communication. This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
TAX REORIENTATION AS CORRUPTION PREVENTION ON INVESTMENT IN INDONESIA
Authors: Dianto Pardamean Sinaga Henry , Hermawan Anis Wahyu
Published: April 2021

Investments, that are supposed to increase the country's economic growth and tax revenues, have potentially created "unofficial" costs for investors and unreported informal income of the bribe recipients. It is important to conduct library research using the new institutionalism theory with historical institutionalism approach in answering the main problem. It is concluded that tax reorientation could prevent corruption on investment in Indonesia. The actors involved in investment, even though, will be limited collectively by government organizations, but the existing restrictions are the design of systems that can influence individuals and groups to prevent corruption. Restrictions of the tax authority can be imposed through several ways, such as enforcing bribes as the non-deductible expense and as an income tax object of gifts to the givers, applying bribes as income to the recipients, recommending non-penal sanctions, and blacklisting the individuals or legal entities involved in corruption.

Authors: Ogbamikhumi Alexander , Ighodalo John Elvis
Published: April 2021

Field development is a very costly endeavor that requires drilling several wells in an attempt to understanding potential prospects. To help reduce the associated cost, this study integrates well and seismic based rock physics analysis with artificial neural network to evaluation identified prospects in the field.

 Results of structural and amplitude maps of three major reservoir levels revealed structural highs typical of roll over anticlines with amplitude expression that conforms to structure at the exploited zone where production is currently ongoing. Across the bounding fault to the prospective zones, only the D_2 reservoir possessed the desired amplitude expression, typical of hydrocarbon presence. To validate the observed amplitude expression at the prospective zone, well and seismic based rock physics analyses were performed. Results from the analysis presented Poisson ratio, Lambda-Rho and Lambda/Mu-Rho ratio as good fluid indicator while Mu-Rho was the preferred lithology indicator.

Machine Learning Boosted Docking (HASTEN): An Open-Source Tool To Accelerate Structure-based Virtual Screening Campaigns
Authors: Kalliokoski Tuomo
Published: April 2021

The software macHine leArning booSTed dockiNg (HASTEN) was developed to accelerate structure-based virtual screening using machine learning models. It has been validated using datasets both from literature (12 datasets, each containing three million molecules docked with FRED) and in-house sources (one dataset of four million compounds docked with Glide). HASTEN showed reasonable performance by having the mean recall value of 0.78 of the top one percent scoring molecules after docking 10 % of the dataset for the literature data, whereas excellent recall value of 0.95 was achieved for the in-house data. The program can be used with any docking- and machine learning methodology, and is freely available from

Published: April 2021

Valorization of biomass to value-added platform compounds shows great potential to relieve the pressure on fossil energy consumption. Gamma (γ)-valerolactone (GVL) is a sustainable liquid for energy and carbon-based chemicals. Despite the numerous researches of investigation regarding the GVL synthesis from carbohydrate biomass, most of them involve the use of precious metals accompanying with the high-purity and high-pressure hydrogen, facing high cost in large-scale application and safety risk during the transportation and operation process. In this work, the cheap metal Fe was employed as a reductant for splitting water to produce hydrogen, and Raney Ni was used as a catalyst for in situ hydrogenation of obtained levulinic acid (LA) which is a key hydrolysate of cellulose to GVL. Cellulose was initially hydrolyzed to LA and then reduced to GVL without separation of other hydrolyzed intermediates of cellulose in one pot. The effect of reaction parameters on the yield of LA and GVL were studied for obtaining the optimal conditions. A 61.9 % yield of GVL from cellulose was achieved at mild hydrothermal conditions. This study provides an efficient approach for direct conversion of carbohydrate biomass to GVL with safe and abundant water as hydrogen source.

The carbon nitride poly(heptazine imide), PHI, has recently emerged as a powerful 2D carbon nitride photocatalyst with intriguing charge storing ability. Yet, insights into how morphology, particle size and defects influence its photophysical properties are virtually absent. Here, ultrasonication is used to systematically tune the particle size as well as concentration of surface functional groups and study their impact. Enhanced photocatalytic activity correlates with an optimal amount of those defects that create shallow trap states in the optical band gap, promoting charge percolation, as evidenced by time-resolved photoluminescence spectroscopy, charge transport studies, and quantum-chemical calculations. Excessive amounts of terminal defects can act as recombination centers and hence, decrease the photocatalytic activity for hydrogen evolution. Re-agglomeration of small particles can, however, partially restore the photocatalytic activity. The type and amount of trap states at the surface can also influence the deposition of the co-catalyst Pt, which is used in hydrogen evolution experiments. Optimized conditions entail improved Pt distribution, as well as an enhanced wettability and colloidal stability. A description of the interplay between these effects is provided to obtain a holistic picture of the size–property–activity relationship in nanoparticulate PHI-type carbon nitrides that can likely be generalized to related photocatalytic systems.

We examine the role of surface passivation on carrier trapping and nonlinear recombination dynamics in hybrid metal-halide perovskites by means of excitation correlation photoluminescence (ECPL) spectroscopy. We find that carrier trapping occurs on subnanosecond timescales in both control (unpassivated) and passivated samples, which is consistent within a shallow-trap model. However, the impact of passivation has a direct effect on both shallow and deep traps. Our results reveal that the effect of passivation of deep traps is responsible for the increase of the carrier lifetimes, while the passivation of shallow traps reduces the excitation density required for shallow-trap saturation. Our work demonstrates how ECPL provides details about the passivation of shallow traps beyond those available via conventional time-resolved photoluminescence techniques.
A Diastereodivergent and Enantioselective Approach to syn- and anti-Diamines: Development of 2-Azatrienes for Cu-Catalyzed Reductive Couplings with Imines that Furnish Allylic Amines
Authors: Zhou Pengfei , Shao Xinxin , Malcolmson Steven
Published: April 2021

We introduce a new reagent class, 2-azatrienes, as a platform for catalytic enantioselective synthesis of allylic amines. Herein, we demonstrate their promise by diasteredivergent and enantioselective synthesis of syn- and anti-1,2-diamines by Cu-bis(phosphine)-catalyzed reductive couplings with imines. With Ph-BPE, anti-diamines are obtained, and with the rarely utilized t-Bu-BDPP, syn-diamines are generated.

Published: April 2021

Pyoderma gangrenosum is rare neutrophilic dermatoses that exist as inflammatory and ulcerative disorders of the skin and is neither an infectious nor gangrenous condition. It is commonly associated with an autoimmune disease like ulcerative colitis and crohn’s disease. It has an estimated incidence of 3-10 cases per million people per year. This is a case of a 28-year-old patient who was admitted with features of pyoderma gangrenosum: papule over the shin of the right leg which progressively increased in size. She had a history of ulcerative colitis and type 2 Diabetes mellitus and developed a papule in the right leg one month back which progressed to a larger ulcer and a similar lesion developing proximal to this. The lesions were painful, two lesions over the right tibial shin each measuring about 5x5cm, with erythema, pedal oedema and associated with fever and She was treated with antibiotics, steroids (hydrocortisone), cyclosporine and other supportive care. Daily dressing of the wound was done, and saline compresses were applied and was advised to continue the same after discharge. With the above measures, she improved clinically and was stable at discharge. As there is no diagnostic test for PG (since it is a diagnosis of exclusion) and if the disease is present but unrecognized, the results can be devastating. Hence timely onset of therapeutic approach is of utmost importance.

Engine and machine oils, better known as lubricant, is a fast-moving part within the motorcycle and automobile industries. Due to its high demand, these oils are often counterfeited by irresponsible people to get more profit. The thing most often done to adulterate oil is by mixing it with other low-quality or used oil. Here, we propose a simple analytical method to identify oil adulteration by using UV-Visible spectroscopy. A number of 425 genuine and adulterated oils were used as samples. After appropriate dilution using n-hexane, the samples were analyzed by UV-Visible spectrophotometer followed by Principle Component Analysis (PCA) and Principle Component Regression (PCR) as part of the chemometrics analysis. The results show that prediction samples were accurately classified into their corresponding groups with PCA scores of 49% and 27% for principal component 1 and 2, respectively. PLS model achieved a good prediction to detect lubricant oil adulteration, with R-Square of predicted and reference samples were 0.9257 and 0.9204, respectively. The proposed method shows a promising alternative to the conventional chemical method using a more sophisticated instruments such as GC-MS and HPLC for oil or other organic compound identification.
