An African perspective on hamartology and ecology: Assessing Jesse Mugambi’s contribution to the contemporary debate
Authors: Cloete Dr. Newton
Published: May 2022

Christian ecotheology offers a Christian critique of ecological destruction while
simultaneously proposing an ecological critique of Christianity. One aspect of Christian
ecotheology entails ecumenical discourse on the content and ecological significance of the Christian faith. This involves a reinterpretation of the classic Christian symbols – in this instance the doctrine of sin, more specifically the nature of sin – explored in the light of ecological discussions. Taking into account the radical diversity in contemporary forms of Christian ecotheology and the contemporary ecological crisis, this paper presents African theologian Jesse Mugambi’s contribution to such discourse. Following a brief overview of the Christian understanding of the nature of sin and how it is re-described in contemporary ecotheological terms, Jesse Mugambi’s position on ecotheological discourse through a discussion of anthropocentrism, domination in the name of differences of species, consumerist greed, alienation of humans from the earth community and sloth (backwardness) is explored. Mugambi’s African context is a key influencing factor in the formulation of his ecotheology. Science and technology, industrialisation, pollution and development are among the prominent emerging themes. The paper involves ecclesial scrutiny, namely Mugambi’s assessment of Christianity’s role in contributing to the current crisis and theological reflection
on ecological sin, followed by alternative courses of action to appropriately attend to the issues in question. In closing, Mugambi’s overall contribution to the current ecotheological debate is assessed.
Oath taking viewed Biblically and perjury by South African Politicians
Authors: Thinane Dr Jonas Sello
Published: May 2022

As it is the case with many other countries around the world, South Africa has a unique and strong tradition of religious devotion, encompassed by belief in God which is even expressed in the constitution’s preamble invoking the presence of God. To ensure that the judicial system carries out its duties responsibly and upholds the fair administration of justice, courts of law, judicial authority and commissions of inquiry discourage perjury by requiring witnesses or the accused to take an oath or certify that the content of their testimony is true and accurate. The recent lenient sentencing whereby the former Minister of Social Development, Ms Bathabile Dlamini was found guilty of perjury has certainly set a bad precedent and created the impression that anyone with more money can lie under oath and buy their way out of the transgression. The case of Ms Bathabile Dlamini is significant both from the perspective of the judicial system and perhaps more importantly from the perspective of the broader religious teachings in general and the Christian teachings in particular, as it points to a society that has lost its Christian ethics and is somewhat polluted by individuals, especially political figures who are conducting themselves as though they are not obliged to take the practice of oath seriously, thus inadvertently seriously questioning the religious doctrines of oaths and even the consequences of lying under oath. This paper will highlight the impact of perjury on both the religious and judicial integrity in a society like South Africa. It argues that the punishment of perjury should firstly, reflect differences in the seriousness of the offense that gave rise to the perjury and, secondly, take into account the public standing of the offender in relation to the extent of his or her influence on society. It then concludes with a plea that, on the one hand, the religious communities, especially Christianity, should strengthen their teachings about taking an oath. On the other hand, the courts must increase the punishment for perjurers, especially if these individuals hold public office.

Authors: Lobunicheva E. , Litvin A. , Dumnich N.
Published: May 2022

The paper analyzes the seasonal dynamics of the composition, structure, and abundance of zooplankton in different parts of the Sheksna Reservoir in 2016–2020. The zooplankton in the reservoir includes 107 species (Rotifera – 41, Cladocera – 41, Copepoda – 25). The authors have found 88 species in Lake Beloye and 90 species in the river part of the reservoir. 7 species in the lake and 17 in the river part of the reservoir have been found for the first time. The communities of different parts of the reservoir are similar in terms of zooplankton composition (76%). The highest level of dominance (0.32–0.38) of zooplankton is observed during the ice period. In Lake Beloye, this figure is higher than in the river part of the reservoir. A small set of species (Kellicottia longispina, Keratella cochlearis, Eudiaptomus gracilis) is characterized by high density in all seasons of the year. Some species are dominant only in certain periods. In summer, rotifers of the genus Polyarthra and Mesocyclops leuckarti dominate the entire water area of the reservoir. Lake Beloye is dominated by Daphnia galeata and Chydorus sphaericus in summer. The composition of the dominant zooplankton complex in different parts of the reservoir is similar in certain seasons. Only in May, the structure of the dominant complex of the lake and river sections of the reservoir differs. The ratio of dominants in Lake Beloye in May is similar to the ice period. The maximum abundance of zooplankton in the reservoir is recorded in summer. From May to November the largest number of copepods is observed. In March, rotifers dominate. Cladocera were noted as dominants only in the lake part of the reservoir. The seasonal dynamics of the structure and abundance of zooplankton generally corresponds to those in the 1970s and early 2000s.
Efeito de Pochonia chlamydosporia em plantas de tomate (Solanum lycopersicum) no comportamento de oviposição e desenvolvimento de Tuta absoluta (Lepidoptera: Gelechiidae)
Authors:   , Santos Kárenn Christiny Pereira
Published: May 2022

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), é uma das principais pragas do tomateiro a nível mundial. Dentre os sistemas disponíveis para o manejo sustentável de pragas agrícolas, tem-se a utilização de antagonistas como agentes de controle biológico e/ou endófitos. As interações endófíto-planta-herbívoro podem influenciar a preferência e o desempenho de insetos herbívoros. Pochonia chlamydosporia é um fungo endofítico de raízes de plantas que promove o crescimento vegetal sem causar lesões na planta hospedeira. É possível que a interação de P. chlamydosporia com as raizes de plantas de tomate possa afetar o perfil de metabólico da planta e alterar o comportamento de oviposição das fêmeas de T. absoluta, bem como o desenvolvimento da fase jovem. Assim, o objetivo do presente trabalho foi determinar o efeito da presença do fungo endofítico P. chlamydosporia nas raizes de plantas de tomate, no comportamento de oviposição e desenvolvimento de indivíduos de T. absoluta. Uma planta inoculada e uma planta controle, separadas diagonalmente 15 cm, foram colocadas numa gaiola de madeira, coberta com organza, onde 4 fêmeas acasaladas de T. absoluta foram liberadas na gaiola e o número de ovos em cada planta foi contado após 12h. Os estágios de desenvolvimento foram também monitorados, e o perfil metabólico dos tratamentos foi feito. Observamos que fêmeas de T. absoluta colocaram uma maior proporção de ovos em plantas controle (55,75%) do que em plantas inoculadas com P. chlamydosporia (44,25%). Ademais, não foi observado alterações no desenvolvimento das larvas. Foram identificados fito- hormônios, flavonóides e fenólicos encontrados na folha das plantas inoculadas e controle, embora sem diferença significativa entre os grupos. Portanto, a presença do fungo, P. chlamydosporia pode afetar a escolha do hospedeiro pelas fêmeas de T. absoluta mesmo sem haver um efeito no desenvolvimento da prole, e mudanças nos metabólitos secundários.

Efeitos da expansão agrícola na disponibilidade hídrica do oeste da Bahia via modelagem hidrológica
Authors:   , Fontes Vitor Cunha
Published: May 2022

O oeste da Bahia passou por uma grande expansão agrícola nos últimos anos e nessa região estão localizados alguns dos maiores produtores agrícolas do Brasil. Por conta disso, entre 1990 e 2015, 31% da vegetação natural da região foi convertida para regiões de pastagem e agricultura. Essa mudança de uso do solo pode ter afetado as vazões dos rios da região. O objetivo desse trabalho é avaliar a magnitude desse impacto. Esse tipo de análise pode ser feito por meio da modelagem. Primeiro foi necessário calibrar os modelos INLAND (Integrated Model of Land Surface Processes) e THMB (Terrestrial Hydrology Model with Biogeochemistry) para simularem a hidrologia da região. Foram calibrados um total de 19 parâmetros resultando numa simulação com um índice de eficiência de Kling-Gupta (KGE) de 0,83 para o período de calibração e de 0,80 para o período de validação. Depois foram simulados cenários sem desmatamento e sem aquífero. A diferença entre o cenário controle e o cenário sem desmatamento mostrou que a substituição da vegetação natural por áreas agrícolas e pastagens aumenta o volume do aquífero (diminuindo a evapotranspiração) e consequentemente a vazão (tanto a média quanto os valores mínimos e máximos). A diferença entre o cenário controle e o cenário sem aquífero mostrou que o aquífero ajuda a estabilizar a vazão mantendo valores mais altos de vazão mínima. Esses resultados, apesar de parecerem positivos, podem estar escondendo uma possível mudança climática que pode diminuir a precipitação da região e no levar no futuro a uma diminuição da vazão. Portanto, é preciso que os tomadores de decisão leve esse estudo como um alerta e passem a monitorar o uso do solo e os seus impactos na vazão para evitar possíveis futuros conflitos no uso da água. Palavras-chave: Calibração. Desmatamento. Aquífero. Vazão.

Authors: Yee Choy Johnn , Salleh Mad Ithnin
Published: May 2022

This research integrated the SERVQUAL model into European perspective of two-dimensional service quality concept focusing on “how” and “what” service quality influence the passenger satisfaction in Grab, ride-hailing services in Malaysia. A second-order model approach was developed to conceptualize the functional quality “how” dimension and outcome quality “what” dimension. Functional quality dimension is measured by the first-orders construct of assurance, empathy, responsiveness and reliability, while the Outcome quality dimension is measured by tangible, waiting time and valence. A non-probability judgmental sampling method via questionnaire was conducted and collect from 242 Grab-ride healing passenger in Malaysia.  Partial least squares structural equation modelling (PLS-SEM) and Statistical Programmers for Social Science software (SPSS) were employed for data analysis. From the PLS-SEM measurement model analysis, all the construct reliability and validity are met and the structural model shows a substantial explanatory power and predictive accuracy for this study. The results show all the hypotheses were supported. Therefore, it validated the European perspective of understanding “how” and “what” service quality on passenger satisfaction in Grab, ride-hailing service in Malaysia.  It further confirmed the service quality in ride-hailing service is multi-dimensional which both of the functional and outcome quality brings significant influence on passenger satisfaction. The model and result provide practical guideline and theoretical insight for service providers and researchers to understand how service should be delivered and what service outcome that passenger expected for future quality and strategy improvement in order to sustain and for long term success.

Authors: Abdul Aziz Abdul Rashid , Mahad Nor Aishah
Published: May 2022

Adolescents between the ages of 13 until 17 begin to get addicted to drugs after being exposed to smoking habit at a young age. These students are also involved with truancy and low academic achievement. Therefore, this case study was conducted to look at the role of the family head in particular the effect of a father's smoking habits on the adolescent’s involvement towards smoking cigarette and drug addiction. The student involved in this case is a Form 5 student referred by the Students Affairs Department due to absenteeism from school and was caught vaping in the school’s toilet. The University of Rhode Island of Change Scale (URICA) inventory was used to measure the client's readiness to change and career interest (Inventori Minat Kerjaya, IMK) to help client in career planning after leaving the school. The counselor conceptualized the client’s case using Reality Therapy. The findings show that the influence of father’s smoking habit may increases a son’s desire to try cigarettes and in turn is involved in a bigger problem of drug addiction. Therefore, parents need to be a positive role model and act as a protective factor in preventing adolescent from getting involved with smoking and drug addiction.

Authors: Amelin V. G. , Shogah Z. А. C. , Bolshakov D. S. , Tretyakov A. V.
Published: May 2022

A combined approach has been developed for the identification and determination of quinolone antibiotics in pharmaceuticals using solid-phase fluorescence digital colorimetry and chemometric analysis. The eigen fluorescence of quinolones and quinolone-sensitized fluorescence of europium(III) have been studied on various matrices. The paper proposes a test-system consisting of four indicator zones. Under irradiation with ultraviolet light (365 nm) of quinolone solutions applied to the indicator zones of test systems, there are observed blue fluorescence on cellulose paper (CP) and plates for high performance thin layer chromatography (HPTLC) and pink (CP–Eu, HPTLC–Eu) fluorescence. The measurement of the fluorescence intensity on the surface of the matrices has been carried out using a smartphone. The possibility of using chemometric analysis, which makes it possible to reduce the analysis time and visualize research data, has been shown. The data array was processed by principal component methods, hierarchical cluster analysis, and the kmean method using the XLSTAT software. The identification and assessment of the quantitative content of quinolone antibiotics in tablet forms have been carried out using chemometric analysis. The calibration dependences in the РСА and k-mean methods have a logarithmic form in the ranges of the determined concentrations of 0.5–250 μg/ml (R2 ≥ 0.98). A technique for the determination of fluoroquinolones in pharmaceuticals has been proposed. The relative standard deviation does not exceed 0.09.

Unveiling the Determinants of Saving-Consumption Relationship: A Panel Data Approach
Authors: Sek S. K. , Lai K. K.
Published: May 2022

The impact of uncertainty on saving is termed as precautionary saving. Thus, the main objective of this study is to investigate the effect of external global uncertainties on determining the saving-consumption relationship. In particular, we seek to compare the effect of two types of uncertainties, namely the monetary policy versus economic policy uncertainties in determining the behavior of saving-consumption. The results are compared between the top trade openness versus the least trade openness countries. Besides, the study also seeks to check for the existence and hence the effect of cross-section dependency in the relationship. For this purpose, the mean group (MG), pooled mean group (PMG) and common correlated effects mean group (CCEMG) estimators are applied. The data is from the year 1985 to 2017. The results reveal the existence and significance effect of cross-section dependence among countries and uncertainties matter in the saving-consumption relationship. The main factors that contribute to savings are the GDP per capita and the economic policy uncertainty while the main factors that contribute to consumptions are the GDP per capita and the monetary policy uncertainty.
Modelling Temperature Using CARMA Processes with Stochastic Speed of Mean Reversion for Temperature Insurance Pricing
Authors: Darus M. , Taib C. M. I. C.
Published: May 2022

In this paper, we present a continuous time autoregressive moving average (CARMA) model with stochastic speed of mean reversion. This model allows the mean reversion rates to behave stochastically and governed by an Ornstein-Uhlenbeck process. We provide closed-form solution to the CARMA with stochastic speed of mean reversion and formulate the price of temperature insurance using spot-forward relationship framework. We demonstrate the insurance pricing based on the cumulative average temperatures (CAT) index by simulating the temperature variations. We found that our proposed model may explain the temperature evolution well and the price of CAT-based index insurance looks reasonable.
Robustness of Modified Non-Separable HaarWavelet Transform and Singular Value Decomposition for Non-blind Digital Image Watermarking

Security is a matter of significant concern for image media. An effective way to protect images is by digital watermarking. This paper introduces a non-blind digital watermarking scheme using modified non-separable Haar wavelet transform (NSHWT), singular value decomposition (SVD), Arnold's cat map, and Rabin-p cryptosystem to embed a binary watermark image into a color cover image. Aside from robustness, security is also prioritized in the scheme. High robustness is achieved using two transform domain techniques, discrete wavelet transform (DWT) and SVD, while security is heightened with the double encryption by Arnold's cat map scrambling and Rabin-p cryptosystem. A disadvantage of the discrete wavelet transform in digital image watermarking is the calculation complexity and the high cost of changing memory and time. The proposed algorithm uses a modified NSHWT instead of the traditional method of DWT. Therefore, the load of the process on the hardware can significantly be reduced while still maintaining the advantages of DWT. The algorithm is objectively evaluated in terms of imperceptibility, robustness, and embedding capacity for both binary and color watermarks, as well as efficiency. It has been concluded that the proposed scheme performs competently compared with other recent watermarking techniques based on DWT and SVD.

Published: May 2022

A hybrid derivative-free double step length technique is proposed in this work in order to enhance the numerical results and convergence properties of the double direction and step length scheme. This is accomplished by combining a Picard-Mann hybrid iterative method proposed by Khan [Fix Point Theory and Applications, pp. 1-10, vol.69 (2013)] with the double step length approach. A derivative line search is employed in order to compute the two step lengths. Furthermore, a suitable acceleration parameter is developed to approximate the Jacobian matrix. Under some mild conditions, the proposed method is shown to converge globally. The numerical experiment presented in this paper illustrates the efficiency of the proposed method over some existing methods.

Objectives: Evaluation of uterine factors is an essential step in the diagnostic workup of subfertile couple. Intrauterine pathologies can impair implantation and hence reduce the endometrial receptivity. The advantage of hysteroscopy is that it not only allows direct observation and accurate localization of pathology but also provides therapeutic treatment for some pathologies in a single setting. This study aims to evaluate the intra uterine condition of the subfertile couple presenting to our centre using hysteroscopy. Materials and Methods: This was a Prospective descriptive study and sixty three cases of subfertility were enrolled during the study period. Hysteroscopy was scheduled in the follicular phase of the menstrual cycle. The detailed hysteroscopic findings were noted. Data was entered in Microsoft excel format and appropriate statistical test was applied. Results: Sixty three patients underwent hysteroscopy, among them forty-eight patients (72.2%) had primary subfertility and fifteen patients (23.8%) had secondary subfertility. Thirty-nine (61.9%) patients had normal hysteroscopic findings whereas twenty-four (38.1%) patients showed abnormal hysteroscopic findings. Common abnormal pathologies were stromal oedema1(n=3,54.16%) followed by intrauterine adhesions (n=8,19%).Twenty-two (45.8%) patients with primary subfertility showed abnormal hysteroscopic findings as compared to only two (13.3%) patients of secondary subfertility which was statistically significant (p value= 0.03). Conclusion: Stromal oedema was the most common hysteroscopic finding followed by intrauterine adhesions which could have been missed during routine diagnostic investigations for subfertility workup.

During the last years, water quality has been threatened due to unprocessed effluents, municipal refuse, factory wastes, junking of compostable and non-compostable effluents has hugely contaminated nature-provided water bodies like rivers, lakes and ponds are pollutants. Therefore, it is necessity to look into the water standards before the usage. Hence modeling and predicting water quality have become very important in controlling water pollution. Safe drinking-water access is essential to health, a basic human right and a component of effective policy for health protection. It is important as a health and development issue at a national, regional and local level. Thus it is a problem that can greatly benefit from Artificial Intelligence (AI). Traditional methods require human inspection and is time consuming. Automatic Machine Learning (AutoML) facilities provide machine learning with push of a button, or, on a minimum level, ensure to retain algorithm execution, data pipelines, and code, generally, are kept from sight and are anticipated to be the stepping stone for normalizing AI. However, it is a field under research still. This project work aims to recognize the areas where an AutoML system falls short or outperforms a traditional expert system built by data scientists. Keeping this as the motive, this project work dives into the Machine Learning (ML) algorithms for comparing AutoML and an expert architecture built by this project for Water Quality Assessment to evaluate the Water Quality Index, which gives the general water quality, and the Water Quality Class, a term classified on the basis of the Water Quality Index using python. In this Project, we are going to implement a water quality prediction using machine learning techniques. In this project, our model predicts, that the water is safe to drink or not, using some parameters like PH value, conductivity, hardness, etc. Finally the results of accuracy level of AutoML and Python compared with conventional ML techniques.

The goal of the project is to create a density-based dynamic traffic light system. When the traffic intensity at the intersection is detected, the signal time adjusts automatically. Many major cities throughout the world are experiencing extreme traffic congestion, which has turned commuters' lives into a nightmare. The traditional traffic signal system is based on a set time notion that is assigned to each side of the intersection and cannot be adjusted to accommodate changing traffic congestion. Junction timings allotted are fixed. In certain cases, heavier traffic congestion on one side of the intersection necessitates a longer green duration than the typical permitted time. The object detection in the traffic signal is processed and transformed into a simulator, after which a threshold is created based on which a contour has been made to compute the number of cars present in the region. After estimating the number of cars, we will be able to determine which side has the highest density depending on which signals will be allocated to that side.

This project presents a smart bike with monitoring system for cyclist via internet of things (IoT). The system is designed for real time monitoring of cyclist in terms of health condition and cyclist's performance. The whole system consists of various sensors such as heart rate sensor, pulse oximetry sensor, magnet reed sensor and GPS module. The sensors are connected to the microcontroller and Wi-Fi module that can be accessed through an IoT platform which is blink application. The data of the cyclist in terms of health condition and cyclist's performance can be monitored by the cyclist as well as their coach. First, heart rate sensor was used to monitor the heart rate of the cyclist within time whereas pulse oximetry sensor was used to measure the oxygen saturation inside the cyclist's body. Meanwhile, magnet reed sensor was mounted to the frame of the bike to measure the speed and distance travelled by the cyclist. Plus, GPS module was used to track and trace the position of the cyclist. The data that have been transmitted can be synchronized or displayed on smartphone via blink application. Therefore, GUI interface of blink application displayed the parameter such as heart rate, pulse oximetry, speed, distance travelled and position for the cyclist and coach to monitor their health condition and cyclist's while in training or tournament. IoT is the internetworking of physical devices, vehicles, and other devices embedded with the electronics, software, sensors and network connectivity that enable to get data of those objects. Confiscating details from their own vehicle without making any physical touch is a hardly possible one. Augmentation of Smartphone makes a large impact in society by diminishing their toil.

The Internet has become an indispensable part of our life, However, It also has provided opportunities to anonymously perform malicious activities like Phishing. Phishers try to deceive their victims by social engineering or creating mock-up websites to steal information such as account ID, username, password from individuals and organizations. Although many methods have been proposed to detect phishing websites, Phishers have evolved their methods to escape from these detection methods. One of the most successful methods for detecting these malicious activities is Machine Learning. This is because most Phishing attacks have some common characteristics which can be identified by machine learning methods. In this paper, we compared the results of multiple machine learning methods for predicting phishing websites.
