Published: April 2020

Though Antarctica has once been considered as the most pristine land on earth, however, recently many literatures concluded that it is not a zone free from anthropogenic pollutants, which have been mostly associated with long-range atmospheric transport and deposition in the area. Numerous organic pollutants including phenol have been classified as the priority pollutants by the United States Environmental Protection Agency (US EPA) due to their high toxicity. The increased level of phenol concentration in the Antarctic environment poses a significant risk to the aquatic as well as terrestrial lives and public health due to its persistence, biomagnification and accumulation in the food chain. Therefore, bioremediation actions are significant to overcome this problem. Phenol degradation at cold climate needs the use of microorganisms that has the ability to thrive and function at low temperatures as well as withstand the toxicity of phenol. The utilisation of native microbes as phenol-degraders has proven the effectiveness of bioremediation even though phenol has anti-microbial properties. This paper discusses the sources and toxicity of phenol, existence and effect of phenol on the Antarctic environment, the potential method for eliminating phenol from the environment and suggestion for future prospect.

Hypercholesterolemia has been linked to weight change and histopathological alteration of male reproductive organs. The epididymis was suggested to be an early target of lipid-related infertility and can be dramatically affected by excess intake of a high cholesterol diet. On the other hand, the interest has been increased towards the use of honey as a prophylactic and therapeutic agent for various diseases. Therefore, the purpose of this study is to investigate the effects of Trihoney (a mixture of Trigona, Mellifera and Tualang) on epididymal weight change and histopathological alterations in hypercholesterolemic male rabbits and compare its effects with atorvastatin. Forty-eight mature male New Zealand white rabbits were divided into 6 groups. Two groups received standard rabbit pellet with 0 and 0.6 g/kg/day of Trihoney respectively while the other four groups received 1% cholesterol diet with 0, 0.3, 0.6 g/kg/day of Trihoney, and 2 mg/kg/day of atorvastatin. After 12 weeks, the rabbits were sacrificed and the epididymides were harvested for evaluation of weight and histopathological changes. Administration of 1% cholesterol diet either alone or in combination with atorvastatin caused a significant reduction in the epididymal weight and epididymal atrophy. Supplementation of Trihoney particularly at the dose of 0.6 g/kg/day improved epididymal weight, regained the normal architecture of the epididymal histology and increased the number of mature sperm inside the tubules of the epididymis. Based on these results, Trihoney exhibited its potential health benefit as a protective agent against epididymal weight reduction and histopathological alterations in hypercholesterolemic rabbits.
Prediction of B-cell epitope by in silico analysis of Mycobacterium tuberculosis Ag85B antigen
Authors: Karimah Nihayatul , Pambudi Sabar
Published: April 2020

Mycobacterium tuberculosis (Mtb) is a causative pathogen of tuberculosis (TB) that emerges as one of the deadliest communicable diseases in Indonesia. The quest for protein biomarkers for TB has been conducted in order to develop a TB diagnostic kit and a TB vaccine. One of the abundant biomarkers in the TB infected human serum is the Ag85B antigen. In this study, we employed immunoinformatic prediction tools such as Ellipro and VaxiJen to predict the B-cell epitopes of Ag85B wildtype and multidrug resistance type (mutant). We then performed molecular docking simulation to evaluate the predicted epitopes using HADDOCK. The screening of both continuous and discontinuous B-cell epitopes using criteria-based analysis resulted in the eight linear epitopes and two conformational epitopes in Ag85B with high antigenicity. The in silico analysis showed no major differences between Ag85B wildtype and Ag85B mutant, implying Ag85B a good target for TB vaccine candidates but not for a specific biomarker that differentiates wild-type and mutant TB.

Published: April 2020

A saúde sexual vai muito além da ausência de Infecções Sexualmente Transmissíveis (IST), embora tal tema tenha se fortalecido como problema de Saúde Pública, pois tem atingido principalmente jovens. Através desse, pretende-se identificar fatores que podem influenciar a vida de jovens que vivenciam o HIV/AIDS. Para tal, lançou-se mão da Revisão Integrativa, a partir da questão norteadora: “Quais fatores tem afetado a vida de jovens soro positivos para o HIV?”. Então, durante novembro de 2019 utilizou-se os descritores “Doenças Sexualmente Transmissíveis”, “Adolescentes” e “Qualidade de Vida” nas Bases de Dados LILACS, MEDLINE e BDENF, ambas reunidas na Biblioteca Virtual em Saúde. Seguindo critérios de inclusão e exclusão se perfez uma amostra final de 16 artigos, os quais foram analisados criticamente. Percebeu-se, portanto que diversos fatores podem influenciar a vida do desse grupo populacional: o sentimento de vergonha; a fragilidade do serviço de saúde para como este público, expressa na ausência de recursos financeiros e carência de informação e conhecimento específicos sobre HIV/IADS; alcoolismo; tabagismo; drogas; discriminação e exclusão familiar, social e cultural; medo; e problemas psicológicos; agressões físicas, desenvolvendo a necessidade de cuidados físicos e psicológicos; baixa escolaridade; sentimentos quanto ao futuro de incerteza, tristeza, raiva; alteração do padrão de sono. Assim sendo, evidencia-se que o público constituído de jovens e adolescentes soropositivos sofrem influências negativas quanto aos aspectos socioeconômicos, sociais e psicossociais de modo que podem interferir no processo saúde-doença e nas relações sociais.

Authors: A.A. Huseynova
Published: April 2020

This study is devoted to the research of ecological and biotechnological aspects of bioconversion of wheat straw by edible mushrooms. It is shown that the efficiency of bioconversion of wheat straw depends on regional climatic factors. The ability of protein synthesis by Pleurotus fungus cultivated on wheat straw was researched. It was also found that the cultivation of edible basidiomycetes on wheat straw leads to the enrichment of plant waste up to 10% proteins. It is shown that the amount of protein in plant substrates is 3% for control sample, the amount of protein in the substrate with the strain Pleurotus ostreatus D5 increased to 12%, P. ostreatus F1 – to 11.47%, P. pulmonarius S6 – to 10.88%, P. pulmonarius F2 - to 9.57%. The analysis of amino acid composition of protein mass obtained by processed of straw recycling by mushrooms is shown the presence of essential amino acids such as valine, methionine, isoleucine, leucine, phenylalanine and lysine. It was found that the adaptation of strains of Pleurotus ostreatus D5, P. ostreatus F1, P. pulmonarius S6, P. pulmonarius F2 to the nutrient media with wheat straw occurs within 1–2 days. It is noted that the characteristic of fungi in the short growth phases is a very important biotechnological criterion for their selection as active producers. The prospect of using fungi in bioconversion of plant waste, including for obtaining nutritious feed, is noted.

Confirming the adoption and use of information technology is central to human-computer interaction. User experience (UX) and Usage Continuance (UC) which latently signifying implementation success are vocal upon this mechanism. The advent of smart phones and mobile technologies such as Geographical Positioning System (GPS) has seen great proliferation in positioning outdoor location. However, GPS is incapable to work in an indoor environment (Hub, 2008) properly. Hence, for navigating indoor location one need to combine the existing mobile technologies and most of their components with location-based augmented reality. In this paper, implementation success of Indoor Navigation with Location-Based Augmented Reality named ‘GuideMe” is studied. The factors considered to evaluate implementation success are adopted from information systems and mobile computer interface literature. The objectives of this paper are to determine users’ experience (satisfaction) and usage continuance of GuideMe. Prior to that, GuideMe has been successfully designed and developed using IOS with tools (Unity engine, Placenote SDK and XCode to set up IOS packages), User feedbacks are gathered via questionnaire forms taken from 35 respondents who volunteer to experiment GuideMe. The volunteers are free to choose and navigate offices at buildings of University of Jeddah (UJ), with the help of GuideMe. The findings of the study conclude that: GuideMe has facilitated users to navigate and seek indoor location independently, conveniently and efficiently since they did not disturb or asked others for directions. Hence, this has improved users’ experience which indicates users’ satisfaction. The high value of mean for “behavioral intention to use” has shown users intend to continue using GuideMe. This is further verified and confirmed by “expectation confirmation” analysis. These findings have the potential to deploy GuideMe to large complexes, such as airports, shopping malls, schools, hospitals and libraries in a cost-effective manner.
Performance Characteristics: The Phase Mimo Radar Technique
Authors:   Department of Electronics & Communication Engineering, Shobhit University, Meerut, India., Singh* Chhabilal
Published: April 2020

The phased-MIMO radar technology is the combination of the phased array and the MIMO (Multiple Input Multiple Output) radar technique. This proposed new technique gives the benefits of MIMO radar without sacrificing the main benefits of phased-array radar, which is the gain in coherent processing on the emission side. The intention of the proposed technique is to divide the transmission network into a number of overlapping subnets. This means that each subnet is used to consistently transmit a waveform that is orthogonal to the waveforms transmitted by the other subnets. The MIMO technique applied to traditional phased array radar has been investigated and has yielded many advantages over the phased array radar system and the MIMO radar. A Coherent processing gain can be obtained by designing a weight vector for each subnet to form a beam in a particular direction in space. The proposed technique compared to the previous techniques, which was a phased array and a MIMO radar, is analytically demonstrated and simulated by MATLAB analysis of the corresponding beam patterns and of the overall beam patterns.

This research intends to carry out the hydraulic model test in Kahayan River for knowing the changes of Kahayan river bed. This model uses 4 model discharge variations that are Q1= 0.798l/sec, Q2= 0.854 l/s, Q3= 0.897 l/sec, Q4= 0.994 l/sec by using the tilting slope (4.58x10-5). The data that are used in this model are flow depth, flow velocity, and the river bed shape after being flowed on each discharge. The result shows that based on the analysis of Froude number, it can said that the flow is as sub-critical type, however, in the beginning of flowing, fraction shows the Froude number is more than 1. This event is only happened in the upstream model. The flow with the Froude number is less than 1 is mentioned as the low flow regime. From the modeling result and it is carried out the bed river contour drawing, it is seen that the configuration of Kahayan river bed is as the ripples type

Satellite signal quality during propagation degrades due to absorption, scattering of the particles in space. For high information rate satellite technologies, this degradation significantly affects the received information. This degradation also depends on the link, atmospheric losses. Rain, cloud imposes a major effect on signal attenuation above 10 GHz frequencies. Low elevation angle transmission during rain, condensed clouds increases the effective path length and causes degradation in the received signal level. The change of transmitted signal parameters like frequency f and elevation angle θ, impacts atmospheric impairments considerably. In this paper, effects free space loss, rain attenuation and cloud attenuation are studied in the frequency range of 10-50 GHz for lower elevation angles. The link calculation method is used for determining free space loss. The ITU-R Rec. P.837-4 and ITU-R Rec. P.676-11 are used for calculation of rain and cloud attenuations respectively. The results of these three losses are plotted and tabulated using MATLAB software.

Published: April 2020

The most critical tools for fine-grained opinion extraction are opinion goals and opinion terms extracted from on-line comments. The key part of this process is to identify the connection between terms. To do this, the Word Alignment Model (WAM) was introduced in which the associated variable can be identified by word alignment by an opinion goal. Nevertheless, its ability to extract opinion words was less successful. In order to determine opinion connections as a process of alignment, the partially supervised Word Alienation Model (PSWAM) has therefore been created. Then a visual co-ranking algorithm was implemented together with the Opinion Relationship Map, to model all the candidates and to measure the confidence of each voter by defining their opinion. In addition, higher-confidence candidates were extracted as opinions or opinions. This method, though, involves an added kind of interaction with terms such as topical connections in graphic thought. Therefore the current relationship is assumed in this report in order to model the applicants and derive the feelings, views and opinions. The efficiency of co-extracting thoughts, viewpoints and issues is enhanced effectively by using this method. The experimental results further indicate that compared to the existing paradigm, the efficiency of the proposed model.

Three billion around people are using wood, cow dung, coal and other conventional fuels inside their homes resulting in indoor pollution. To conquer the said problem, solar energy cooking is the only solution. A large amount of solar energy is available in various parts of the world, which is pollution-free and easy to harness. More than 36% of the total generated energy is consumed for cooking in India. Hence there is a need to develop alternative cooking mode which will be easy, pollution-free and economical. However, the utilization of this form of energy at a large scale is only possible by developing an efficient cooking system with solar thermal energy storage technology and conventional cooking option which will enable the odd hours cooking. In this review paper, an attempt has been made to study the history and recent advancement in the field of solar energy cooking. The paper provides a detailed review of such kind of technology with cooking principle, types of cookers and their performance. Moreover, the review has been done on the use of Phase Change Material (PCM) in a solar cooking system which enables the night cooking.

Term weighting is a preprocessing phase that has an important role in the text classification by giving the appropriate weight for each term in all documents. In previous research, many supervised term weighting methods have been introduced, but most of the supervised term weighting only considers the distribution of terms in the two classes so that it is not optimal for the multi-class classification. This paper introduces a new supervised weighting with association concept to optimize term weighting distributions in multi-class cases by considering terms that exist in each class and paying attention to the number of terms in the document belonging to the class, also considering the relationship pattern between one or more items with association concept in a dataset to measure the strength of terms in a class by using confidence values. The dataset used are the data twitter taken from the PR FM twitter account. The proposed supervised term weighting method implemented with SVM classifier can outperform unsupervised weighting schemes such as TF-IDF with the average accuracy 81.704%.

The past researches on key elements responsible for the successful completion of the project showed the importance of assessment and accounting of various types of risks during the bid decision process. If the contractor invests his productive time in only those projects which are meeting the organization’s goals and targets, then the chances of submitting a competitive bid is more. In order to select such appropriate projects, the measure of the effect of numerous factors on bid decision is essential. This research highlights the numerous reasons that influences the bid decisions of contractors and the contribution of these factors towards the construction of Decision Support System Models (DSS). In order to identify the factors influencing the bid decisions, past literature studies were conducted and a strong focus was given to methods such as questionnaire survey, structured and semi-structured interviews were used. The construction of the models was done after taking the opinions of contractors. From the past research it can be noted that the main factors such as client’s financial capability, contractor’s financial capability, past experience of the contractors in similar projects etc., were considered across the globe. This complex and dynamic nature of bid decision making demands a robust decision support system which can be implemented collectively at least in a construction industry within a country. Moreover, the bid decision is more of subjective in nature. So, addressing this with only quantitative models which considers past bid data, recently applied strategy etc., may not be adequate to forecast the dynamic phenomenon. This strongly proposes the requirement for development of a Qualitative model to take care of subjective decision-making situation.

The proficiency in English language has become a necessity in the modern world. The competency of using the language efficiently lies in the right choice of words. Learning words and improving vocabulary skills have become peremptory among the tertiary level students that they cannot exempt themselves from learning it. A large vocabulary collection allows the students to regulate and organise their thoughts with clarity. In order to facilitate effective use of words, many techniques, approaches and strategies have been devised by teacher-researchers to help the learners not only in acquiring wide vocabulary but also to have active vocabulary. Authors on realizing the importance of facilitating tertiary level engineering students not only to acquire wider vocabulary but also make them to understand, retain and use the learnt word appropriately have attempted to use cognitive learning activities in classroom. The paper registers methods and implications of cognitive learning activities on enhancing vocabulary of a set of 55 engineering college students. According to oxford English dictionary, Cognition is "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". This brings about many aspects such as attention, memory, reasoning, problem solving, decision making and production of language. The ultimate aim of incorporating cognitive learning approach through learning activities in a classroom gears up them to remember, understand, retain, apply, evaluate, and create. The researcher tried to bring out the classroom learning activities that enabled the students to develop learning strategies that instigates autonomous learning.

In this work, an effort is made towards the design and implementation of dual stage multi-rate digital filter architecture which is suitable for digital receivers and satellite applications with reduced VLSI cost function. The proposed dual stage decimation filter architecture consists of Higher Order Filter (HDF) as first section. To remove the droops created by the HDF section in the pass band and to get the smooth pass band frequency response characteristics, HDF filter is followed by a Corrector/Compensating Finite Impulse Response (FIR) filter network. The compensating FIR is designed using conventional Multiplier and Accumulator (MAC) unit. Initially, the filter architectures frequency response are obtained as per the given specifications using MATLAB. Then, Field Programmable Gate Array (FPGA) based performance metrics are captured and analyzed with respect to area, dynamic power dissipation, delay and power delay product. Based on the FPGA performance metrics, it is observed that the proposed dual stage filter leads to 22% of area saving and 9.5 % reduction in dynamic power dissipation. Mainly these filters are best suited for Digital Signal Processing applications in wireless receivers.

Now-a-days, image processing is extensively used for analysis of several biomedical images to identify the complications in one’s health. Most of the solutions offered are based on application software. Since these solutions are expensive, an embedded system approach is being explored in the recent years, considering its cost-effectiveness. This paper propounds an embedded system approach to identify exudates in retinal images. These exudates are often identified as indicators of a medical disorder known as Diabetic Retinopathy, which is one of the medical complications that arise due to high blood sugar levels. The algorithm employs statistical analysis using histogram to enhance the contrast of the images, thus assisting in extracting exudates by utilising the elementary concepts of image processing. Since the pixel characteristics of exudates and optic disk match, it becomes inevitable to first eliminate optic disk from retinal images, and then extract exudates. The prototype has been developed on MATLAB and is downloaded on an Artix 7 FPGA with minimal usage of its resources. The system proposed in this paper results in an accuracy of 90%.

Forced Grading Systems are popular and accepted for evaluating students, particularly in business schools. Under such systems students' numerical test scores are converted to letter grades (A, B, etc.) and awarded in mandated percentages. In common practice, schools mandate that 10% to 15% of students in a class receive As, 25% to 35% Bs, and 40% to 50% Cs. However, instructors must identify what numerical cutoffs satisfy mandated grade distributions, and that tedious effort might entail several solutions. This study introduces an Excel-based template with which instructors can establish numerical cutoffs that distribute students' grades in accord with mandated standards. Results indicate that the spreadsheet template is an efficient tool to evaluate students following the Forced Grading System

The classification of hyperspectral images is a challenging task since it contains unbalanced ratio between the training and testing samples, and number of spectral bands. The detailed spectral data of hyperspectral images increases the ability to individualize the different classes and achieving accurate classification maps. Hence, in this paper, we use spectral data for classification and we address the performance of different supervised classification techniques like logic-based, ensemble-based, statistical-based, non-probabilistic-based and instance-based techniques on spectral features. Experiments are carried out using hyperspectral imagery captured by AVIRIS sensor such as Indian Pines, Salinas and Salinas-A. The appraisal of these supervised classification methods are held with each other in terms of performance metrics such as overall accuracy, precision, recall, F1-score and execution time.

Unmanned aerial vehicles are widely used in military and civilian fields in recent years. Quadrotor Unmanned Aerial Vehicles (UAV) have high advantage among other UAV’s, in different categories, due to their ability to hover, and Vertical Take-Off and Landing (VTOL) capability. The mathematical simulation method can be adopted for analysis of UAV. The simulation method can reduce the flight period, cost and risk and improve its performance while Vertical take-off and landing (VTOL). While landing of UAV, the kinetic energy of vehicle is absorbed by UAV frame resulting in high stress concentration. The stresses are also produced in other parts of the UAV. The effect of the landing loads and stresses on the airframe of the quadrotor unmanned air vehicle must be completely understood and the UAV must be designed accordingly in order not to damage during landing.These stresses can be analyzed by simulation method to ensure the sustainability of UAV structure. This work includes structural and frequency analysis for Quadrotor UAV chassis.
