Marine organisms are frequently exposed to pollutants, including trace metals, derived from natural and anthropogenic activities. In order to prevent environmental pollution, different approaches have been applied to remove pollutants from waste water and avoid their discharge into aquatic systems. However, organisms in their natural aquatic environments are also exposed to physico-chemical changes derived from climate change-related factors, including temperature increase. According to recent studies, warming has a negative impact on marine wildlife, with known effects on organisms physiological and biochemical performance. Recently, a material based on graphene oxide (GO) functionalized with polyethyleneimine (PEI) proved to be effective in the remediation of mercury (Hg) contaminated water. Nevertheless, no information is available on the toxic impacts of such remediated water towards aquatic systems, neither under actual nor predicted temperature conditions. For this, the present study assessed the toxicity of seawater, previously contaminated with Hg and remediated by GO-PEI, using the clam species Ruditapes philippinarum exposed to actual and a predicted temperature conditions. The results obtained demonstrated that seawater contaminated with Hg and/or Hg+GO-PEI induced higher toxicity in clams exposed to 17 and 22 °C compared to organisms exposed to remediated seawater at the same temperatures. Moreover, similar histological and biochemical results were observed between organisms exposed to control and remediated seawater, independently of the temperatures (17 and 21 °C), highlighting the potential use of GO-PEI to remediate Hg from seawater without significant toxicity issues to the selected marine species.

Published: August 2020

The Tarim River (TR), the longest inland river at an arid area in China, plays a critical role in the sustainable development of the regional ecological environment. This study presents the spatial-temporal variations in the vegetation coverage at regional and pixel scales and its driving factors on the TR mainstream. The latest dataset of normalized difference vegetation index (NDVI) and a vegetation coverage index (fc) over the period from 2000–2015 were analyzed with the unary linear regression and the partial correlation. On the basis of land use data, we further built the landscape ecological risk index and assessed the ecological risk level of the mainstream. Our results suggest that the vegetation coverage index demonstrated fluctuations but denoted a generally upward trend in the TR mainstream, the vegetation improvement areas are far greater than the degraded areas during the study period. Apparently, the overflow days in the TR mainstream and the cumulative amount of water transport are the two main factors that dominate the vegetation coverage. The ecological risk level varies throughout the TR with a high-to-low spatial distribution from upstream to downstream, and the overall landscape ecological risk of the whole basin exhibits an upward tendency. Above all, our study provides a framework with the remote sensing data to assess vegetation coverage and landscape ecological risk which can help design and implement reliable strategies for the ecological management and vegetation restoration in the Tarim River Basin.
Numerical Simulation of the Flow Field Characteristics of Stationary Two-Pipe Vehicles under Different Spacings
Authors: Jia Xiaomeng , Sun Xihuan , Li Yongye
Published: August 2020

The piped hydraulic transportation of tube-contained raw material is a new long- distance transportation technology. This technology has the advantages of high efficiency, energy savings and environmental protection. The research in the published literature has mostly been limited to the speed, flow field, pressure field and energy consumption of a single-pipe vehicle. With the continuous improvement and development of this technology, two-pipe vehicles will become the focus of future research. The change of the vehicle spacing will affect the starting speed, flow field distribution and pressure drop characteristics of the water flow within the pipeline; thus, a numerical simulation is used in this work to study the hydraulic characteristics of stationary two-pipe vehicles under different spacings and compare them with physical experiments. The results show that the simulation results are in good agreement with the experimental results, which indicates that it is feasible to study two-pipe vehicles using numerical simulation. The results also show that, as the vehicle spacing increases, the interaction between the two-pipe vehicles gradually weakens. When the vehicle spacing reaches 4 l (where l represents the length of a single-pipe vehicle), the interaction between the two-pipe vehicles becomes negligible. There is no vortex shedding in the pipeline under different vehicle spacings. This study provides a reference for choosing the proper spacing between two-pipe vehicles and provides a theoretical basis for further research on the hydraulic characteristics of two-pipe vehicles in motion.

Published: August 2020

A 2-D numerical wave tank (NWT) was applied for solving the interaction between a solitary wave and a moving circular cylinder. The cylinder was placed at various positions from the tank bed floor. The cylinder can move at a constant horizontal velocity towards the solitary wave. The collision between a solitary wave and a moving cylinder is investigated at various conditions. A total of fifteen cases were studied. Ten different numerical simulations were used, including five submergence depths and two different moving velocities. The other five different numerical simulations were studied when the cylinder was unmoved in the NWT for comparing wave-structure interaction results between the moving and unmoved cylinders. The numerical results were obtained by calculating Reynolds-Averaged Navier-Stokes (RANS) equations and the volume of fluid (VOF) equations. Two different codes (User-Define-Function-UDF) were used for the generation of a solitary wave by moving a wave paddle and traveling cylinder in the NWT. The dynamic mesh method was applied for recreating mesh. First, the ability of CFD codes to generate a solitary wave by using wave paddle movement and the hydrodynamic forces of a moving cylinder were validated by numerical results. Further, the free-surface elevation and hydrodynamic forces were considered at various conditions. The numerical results show that moving cylinder velocity and the space between the cylinder and the tank bed floor have significant effects on surface displacement and hydrodynamic forces.

The coasts of the Mediterranean Sea are dynamic habitats in which human activities have been conducted for centuries and which feature micro-tidal environments with about 0.40 m of range. For this reason, human settlements are still concentrated along a narrow coastline strip, where any change in the sea level and coastal dynamics may impact anthropic activities. In the frame of the RITMARE and the Copernicus Projects, we analyzed light detection and ranging (LiDAR) and Copernicus Earth Observation data to provide estimates of potential marine submersion for 2100 for 16 small-sized coastal plains located in the Italian peninsula and four Mediterranean countries (France, Spain, Tunisia, Cyprus) all characterized by different geological, tectonic and morphological features. The objective of this multidisciplinary study is to provide the first maps of sea-level rise scenarios for 2100 for the IPCC RCP 8.5 and Rahmstorf (2007) projections for the above affected coastal zones, which are the locations of touristic resorts, railways, airports and heritage sites. On the basis of our model (eustatic projection for 2100, glaciohydrostasy values and tectonic vertical movement), we provide 16 high-definition submersion maps. We estimated a potential loss of land for the above areas of between about 148 km2 (IPCC-RCP8.5 scenario) and 192 km2 (Rahmstorf scenario), along a coastline length of about 400 km.
Studying the Effect of Channel Geometry on Different Water Quality Variables for Effective Designs and Waste Allocation Plans for Waterways
Authors: Baradei Sherine
Published: August 2020

It is necessary to study the parameters that affect water quality in order to devise mitigation measures if water quality would be at risk or negatively affected by those parameters. Those parameters are physical, chemical, biological, and hydraulic characteristics. This research will study the effect of channel geometry on different water quality variables, which is important in designing new irrigation canals in order to see how its geometry will affect water quality and lessen any negative impact if possible; also this study could aid in designing more reliable waste allocation plans for waterways. The studied geometric characteristics are top width, bottom width, water depth, side-slopes and channel length. Sheikh Zayed canal in Egypt is taken as the reference case study canal. Studied water quality variables are algae, nutrients, total dissolved solids (TDS), total suspended solids (TSS), pH, alkalinity and total inorganic carbon. It was found that concentrations of all water quality variables in water changed as a result of changing channel geometry. Some water quality variables such as algae, nutrients, and TSS are greatly affected, whereas others such as pH, alkalinity and total inorganic carbon are slightly affected.

BNIMS: Block-based Non-iterative Mean-shift Segmentation algorithm for Medical Images
Authors: Naik P. Pedda Sadhu , Gopal T. Venu
Published: August 2020

This paper proposed a novel Block based Mean Shift Image Segmentation Algorithm to significantly reduce the computation and improve the segmentation accuracy for high resolution Medical Image. One of the challenging tasks in the image analysis and computer vision area is to correctly classify the pixels as there are no crisp borders among entities in an image. In this proposed methodology, it is observed that the computational complexity of the procedure is diminished by combining the pixels of an image of size MXN into non overlapping image blocks of size 3x3 by eliminating the iterative way of the mean shift procedure. This proposed algorithm shrinks the size of the image by one third of its original image for the computational purpose and then equalizes the number of computations for each new image pixel by constructing links between pixels using their first mean-shift vectors without any iteration process. The accurateness and effectiveness of the proposed methodology is matched with the existing Iterative Mean Shift Algorithm by accomplishing the empherical experiments on the Medical Images (Pathologies Buccales and Eye Retina) composed along with the similarity measures.

ECG is basically the graphical representation of the electrical activity of cardiac muscles duringcontraction and release stages. It helps in determination of the cardiac arrhythmias in a well manner. Due to thisearly detection of arrhythmias can be done properly. In other words we can say that the bio-potentials generated bythe cardiac muscles results in an electrical signal called Electro-cardiogram (ECG). It acts as a vital physiologicalparameter, which is being used exclusively to know the state of the cardiac patients. Feature extraction of ECG playsa vital role in the manual as well as automatic analysis of ECG. In this paper the study of the concept of patternrecognition of ECG is done. It refers to the classification of data patterns and characterizing them into classes ofpredefined set. The analysis ECG signal falls under the application of pattern recognition. The ECG signal generatedwaveform gives almost all information about activity of the heart. The ECG signal feature extraction parameters suchas spectral entropy, Poincare plot and Lyapunov exponent are used for study in this paper .This paper also includesartificial neural network as a classifier for identifying the abnormalities of heart disease.

Authors: Mutua Paul W. , Mbuthia Mwangi
Published: August 2020

This paper describes the design of an intelligent energy efficient lighting system that uses multi-colouredLEDs and a fuzzy logic controller to produce light of the required luminance level and colour in a typical roomspace. The lighting system incorporates automatic control of a room’s window shade opening, convenientlyharvesting daylight. Appropriate room occupancy sensors were set to dim off the LEDs if there are no people in theroom. A movement sensor was also considered for dimming the LEDs if the persons in the room are asleep. A colourdecoder was included in the control system, to determine the LEDs’ output light colour and dim them off if the colourrequirement is not selected. The colour decoder also closes the window shade if required light colour is not white.Two Fuzzy Logic controllers were used in the system; one to control opening of the room’s window shade viamicrocontroller, and the other to control the LEDs’ output luminance. The study was limited to simulation of thedesign in a MATLAB software environment using Fuzzy Logic Toolbox and Simulink blocks. The simulation testresults confirmed that the LEDs’ output luminance decreases as the amount of daylight entering the room increases.The designed system intelligently saves lighting electrical energy while maintaining the room’s comfortableillumination levels and colour requirements.

Consolidating Democracy in Kenya (1920-1963)
Authors: Gathogo Julius
Published: August 2020

This article sets out to trace the road to democracy in the colonial Kenya, though with a bias to electoral contests, from 1920 to 1963. With its own elected leaders, the article hypothesizes, a society has a critical foundation because elected people are ordinarily meant to address cutting-edge issues facing a given society. Such concerns would include: socio-economic concerns such as poverty, corruption, racism, marginalization of minority, ethnic bigotry, economic rejuvenation, gender justice, and health of the people among other concerns. Methodologically, the article focusses more on the 1920 and the 1957 general elections. This is due to their unique positioning in the Kenyan historiography. In 1920, for instance, a semblance of democracy was witnessed in Kenya when the European-Settler-Farmers’ inspired elections took place, after their earlier protests in 1911.
Rethinking land and religion
Authors: Mukuka Bridget N.M
Published: August 2020

This article is a by-product of a missiological research that examined the power of naming some congregations in the local language, through the concept of culture in the Mutima Walowa wa Makumbi1 Church popularly known as the Mutima Church of Zambia. The article examines how the founder of the Mutima Church acquired land in the name of religion in many parts of the country. Upon the death of the church founder in February 2015, some of the land has been repossessed by either his own relatives or by the Zambian government. To gain ‘ownership’ of the land, the church founder established some congregations across the country which he named under his own Bemba2 cultural worldview. Critically important is the fact that this research was conducted in six congregations; and strongly indicates that due to lack of proper documentation, some acres of church land have been repossessed by the government and by some relatives of the church founder who donated it a couple of years ago. To make the research valid, thirty church members were interviewed. They comprised of eleven males, nine females, six male youths and four female youths. Data were collected through in-depth interviews, focus group approach, participant observation and document review. Consequently, guided by the feminist narrative methods of inquiry, the article adopts a qualitative approach to answer a key research question: How does the missional policy of the Mutima Church affect some members’ understanding of land and religion in the power of naming? The above discourse is viewed through the lenses of Michel Foucault (1978) and Elisabeth Schussler Fiorenza’s (2009) respectively.
Multiliteracies in Rural Schools:
Authors: Morita-Mullaney Trish , Li Haiyan , Renn Jennifer
Published: August 2020

Multiliteracies is a paradigm for language and literacy, in which all languages and literacies are valuable, meaningful, and serve a purpose in meeting the needs of the learner within their social contexts. Multiliteracies are enacted and negotiated through different languages, technologies, and modalities and are represented in homes and communities of English Learners (ELs) or emergent bilinguals (EBs), representing their bi- or multilingual identities. Within rural communities, these family multiliteracies differ from the predominantly English-monolingual contexts found within schools, but have the potential to reshape rural educators’ conceptions of literacies. Redefining literacy holds significance in rural communities where resources, including highly qualified teachers, are often scarce or distant.
Employing a collective-case study, our study explores the family-based literacy practices of 20 EB families from two rural Midwestern communities. Findings demonstrate that family’s home literacies are associated with complex multilingual and multimodal practices.

Gender Division of Domestic Roles: Implications for Social Equality in Nigeria
Authors: Egbue Ngozi G.
Published: August 2020

Gender inequality constrains economic growth in developing countries. In line with this, gendered division of roles, with particular focus on the domestic sphere, stretches women’s work hours very much beyond those of men, and also engenders lower valuation for women’s work at the domestic as well as macro levels. Although there are recent changes in domestic role division in Nigeria, it still manifests powerful undertones of inequality. This inequality tends to be re-enacted at the macro level in gender based divisions that impinge upon women’s optimal labour force participation necessary for sustainable development. At the domestic level, gender inequality sustains various forms of subordination and injustice including violence against women, and the denial of reproductive rights, inheritance, and other fundamental rights denied women. This paper is a theoretical review of the relationships between gendered domestic role segregation, gender inequality and women’s contribution to sustainable development in Nigeria. The paper concludes by positing some recommendations regarding potential interventions for substantial reduction in domestic and other related forms of gendered inequality.
Information Communication Technologies’ Time-Space Distanciation and Crime in Lagos
Authors: Oyenuga A.S. , Odunaike B.A. , Olaitan M.F.
Published: August 2020

Crime is an integral part of every society. To a very large extent, it affects adequate functioning of the society. Over millennia, as the society has evolved, the patterns of perpetrating crime have also evolved. With globalisation and its inherent dependence on Information Communication Technologies (ICTs), new waves of crimes have swept the entire global community. Through time-space distanciation, these technologies have, on one hand, enhanced the traditional crimes and, on the other hand, created new waves of crimes. This study examines the effects of the coverage of ICTs on the perpetration of crime from and in Lagos and societal perception of those involved in cybercrimes. This study adopts the qualitative method of data collection. Four areas in Lagos were randomly selected based on their differential level of development and varying access to the digital world, and four focus group discussion sessions were held. Four case studies of those involved in cybercrimes were also conducted in each area. Content analysis was used for the analysis of data and ethnographic summaries were used to buttress the main themes of the findings that were deduced from the content analysis. The study found that the coverage of ICTs has positive effect on the existence of new waves of crime in Lagos. The farther a settlement is from the core and industrial part of Lagos, the lower the prevalence of these new waves of crime. Since all settlements in Lagos are woven into the wool of social interaction, these new waves of crime inevitably grow.
Prevalence and Consequences of Ewu-ukwu Custom in Mbaise, Imo State, Nigeria
Authors: Isiugo-Abanihe Uche C. , Nwokocha Ezebunwa E.
Published: August 2020

Studies have consistently shown that fertility among the Igbo of Southeast Nigeria is high, and particularly higher among the Mbaise people. Multiple socio-economic and cultural factors such as son preference, stigma and discrimination ascribed to childlessness and other relevant practices in different communities bolster frequent child-bearing among Igbo women even without prompting from their husbands and, at times in conditions that threaten their lives. In Mbaise in particular, the ewu-ukwu custom which is celebrated to honour a woman after her tenth child is perceived as an index of accomplishment and self-actualization. The objectives of the study are to examine the prevalence of the ewu-ukwu custom in Mbaise, and to identify the categories of people who are breaking with the tradition by discontinuing the practice and the factors motivating them to do so. Furthermore, the consequences of the custom on maternal and child health as well as on care and welfare of young people was explored. The findings indicate that the custom has waned, but as long as it lasted, the quest for induction into this relatively privileged social group shored up high fertility, and is associated with high maternal and infant mortality and morbidity which are themselves exacerbated by poor health facilities. Also, the ewu-ukwu custom has multidimensional
implications for the wellbeing and gender roles of relevant individuals and groups which call for urgent interventions and societal re-orientation.
Correlates of Fertility in a Low Contraception Setting: A Study of Ogu of South-Western Nigeria
Authors: Wusu Onipede
Published: August 2020

Total fertility rate in Nigeria is 5.7 compared with over 8 in the past. Modern contraceptive use within marriage is very low and socio-economic development is still crawling. What factors account for this fragile transition? This question is the focus of this study. The study examines the socioeconomic and cultural factors that account for fertility transition in the country. Data were gathered through a survey conducted among the Ogu of south-western Nigeria. Analysis employed descriptive statistical tools and Ordinary Least Square model. Analysis reveals that post primary education (especially among women), spousal discussion about family size, monogamous marriage and age at first marriage were inversely related to children ever born (CEB) among men and female respondents. The result suggests that moderate improvement in these factors are likely responsible for the fragile transition. Therefore, policies to raise literacy level especially among women, increase age at first marriage, promote monogamous marriage and spousal communication may accelerate the fragile transition in the country.
Media Exposure and Reproductive Behaviour Change among Generations of Adolescents in Ugep, Nigeria
Authors: Obono Koblowe , Obono Oka
Published: August 2020

This paper examines change in reproductive behaviour across several generations of adolescent girls in Ugep, southern Nigeria. It is based on a study of key factors promoting differences in girls’ reproductive behaviour across these generations, which linked this change to media exposure and a number of social variables that challenge traditional views of the relationships. The study found alterations in adolescent sexual activities, contraceptive prevalence, voluntary abortion and the fertility. Female age at sexual debut was found to be declining, with 11.3% of adolescent females initiating sex at 11 years relative to 4.1 percent from previous cohorts. This finding in particular reflects the onset of liberal sexual norms, accentuated by ease of entry into consensual unions and trends towards sexual networking. The general findings point to the role of western media, poverty and pressures related to an urbanizing lifestyle on girls’ aspirations and reproductive choices. In this way, it contributes to the growing body of work on reproductive change in an era of serious population debate and, therefore, suggests a need for adopting alternative models for explaining reproductive change in sub-Saharan communities.

The Board of National Accreditation Body for Higher Education) evaluates the performance of a study program. This compels it to improve and maintain its performance. The process of accreditation involves several steps, one of which is the completion of accreditation documents by the study program. The completion requires data from various sources, both from the study program and the institution. However, the data required are often not recorded properly and kept by different sources. As a result, it takes longer time to complete the arrangement. Moreover, inconsistent data format becomes another factor which holds back this process. The application of fuzzy inference system, as used by Kesatuan Business and Informatics Institute, as in the above case can result in a better scoring in which each component is assessed and it will yield the prediction of the expected accreditation status before it is submitted to BAN-PT. This research aims to develop a web based accreditation system with fuzzy inference system and construct a prediction of score ad accreditation status in IBI Kesatuan, using 4 variables of input assessment criteria, namely: external condition, institutional profile, criteria and analysis, and development program decision. The resulting output is the status of non- accredited, good accredited, excellent accredited, and superior accredited. There are 4 phases in the methods: problem identification, needs and system analysis, system design, system implementation and testing system. The result of blackbox test show that 8 features can operate well. The features consist of criteria menu, indicator menu, date user, LKPS data, LED data, LKPS and LED assessment input, recapitulation and conclusion. Based on the results of the study, it can be concluded that accreditation system can be applied to predict the scores and accreditation status of information system study program of IBI Kesatuan.

Authors: Widayaka Parama Diptya , Jauhari Lutfi
Published: August 2020

Water pipe leakage causes financial loss for the user such as PAM or PDAM. YF-S201B flowmeter sensor is a water flow sensor made of plastic with a rotor and hall effect sensor inside. The rotor will spin when the water flow through the sensor. The speed of rotor spin is proportional to the water flow. The hall effect based sensor can be used to detect water flow up to 30 liter/minute (1.800L/hour) thus, the sensor can be used to control the water flow in distribution system and water debit monitoring. The principle of prototype is the placement of sensor before the leakage and after leakage position to obtain different value of water debit. The system will send a short message automatically to the phone if water leakage is detected in the pipeline.

Activity monitoring in online group meetings has become a needed application in the COVID-19 situation. During the lockdown period, most of the teaching classes were conducted through online web applications. The number of attendees in such classes are very higher and it is not to be manageable by a single tutor of the class. The applications are also designed to show only several number of person’s faces in a particular window. To improve the quality of such online classes, it is mandatory to verify the listener’s activity. The paper evaluates certain artificial intelligence based deep learning techniques for finding a suitable approach for monitoring the listener’s activity in real time.

В условиях Республики Крым была дана оценка влияния внекорневой подкормки на основе препарата «Лигногумат» на урожай и качество винограда и плодовых культур. Экспериментальные исследования проводились в течение 2019 г. на винограде (Филиал «Морское» ПАО «Массандра»); на яблоне (АО «Артвин» Бахчисарайский р-н.), на персике и черешне (КФХ «Агрополис», Кировский р-н). Наши исследования показали, что применение препарата «Лигногумат» во внекорневых подкормках способствовало повышению урожайности винограда на 11,6 – 19,8 %, яблони – на 21,6%, персика – на 28,7% и черешни – на 15,2% Препарат оказал положительное влияние на органолептические показатели винограда: общая дегустационная оценка опытных образцов превысила контроль на 13,7 – 30,1%. Наиболее высокими органолептическими показателями (9,5 балла) характеризовался виноград в опыте с применением поливов и 6-тикратной внекорневой подкормкой. Внекорневая подкормка препаратом «Лигногумат» оказала положительное влияние на кондиционные показатели: массовая концентрация сахаров у плодов яблони увеличилась на 3,4%, у плодов персика – на 8,1%, у плодов черешни – на 16,2%. Суммарное содержание хлорофилла увеличилось в листьях яблони на 13,7% (2,65 мг/л), персика – на 7,1% (3,33 мг/л) и черешни – на 5,4% (3,69 мг/л).

На основании результатов исследований по изучению особенностей биологического развития антракноза выявлено, что семена, выделенные из сильно пораженных плодов несут в себе внутреннюю инфекцию Cоlletotrichum lagenarium E.et H. и могут являться источниками возобновления и распространения болезни. При организации семеноводства бахчевых культур необходимо выделять семена из здоровых плодов. В условиях орошаемого земледелия Нижнего Поволжья капельный полив снижает пораженность бахчевых культур антракнозом.

Lead-cadmium intoxication is an occupational risk factor for copper-smelting industry workers. People inhabiting the areas near the copper plants are also at risk. Subchronic intoxication was modeled by repeated intraperitoneal injections of lead acetate and cadmium chloride both in isolation and in combination, 3 times a week for 6 weeks. A heart rate decrease in animals with Cd intoxication and a blood flow velocity decrease in those with Pb intoxication have been found. The impact of Pb and Cd on blood pressure proved to be contra-directional. ECG analysis revealed a prolonged duration of QRS in Cd intoxication, a prolonged QT interval and a baseline lowering in Pb+Cd intoxication. A variety of changes has been found with respect to the diameter of cardiomyocytes and the thickness of aortic wall layers in Pb and/or Cd intoxication. Any toxic exposure resulted in the decrease in number of nuclei per unit area of myocardium histological preparation.
