The ancient vedic mathematics has a set of 16 sutras and 13 subsutras. These sutras give suitable method for arithmetic calculations. The vedic formulas requires less time than the regular formulas or method of calculations [1]. Multiplier is an important block in many digital systems. This paper presents a 32-bit vedic multiplier using Urdhva Tiryagbhyam sutra of ancient vedic mathematics. The 32-bit vedic multiplier is implemented using 16-bit multipliers and adders. The 16-bit multipliers are basic blocks in the design by which the input bits are multiplied and their result are added by using the adders. The vedic multiplier can be used in many fast computing processors because of their less time delay and less number of slice LUTs. The result discusses the delay and number of slice LUTs for the implemented 32-bit multiplier. The paper also discusses the methodology of implementation.

Most of the multi-storey buildings are analysed based on an assumption that the structure is subjected to whole load after modelling the entire structure. But in reality, each storey is subjected to some assumed loads to act during construction period itself as they are constructed in stages as storey wise. Sequential analysis in a structure is ignored by many structural engineers while analysing the structure. Because of this ignorance, variation may occur in structural members in the below storey with respect to above storey as the construction proceeds which leads to incorrect distribution of forces in the member. So, analysis has to be done only by sequential application of loads in each storey for the safety of the structure and cost-effectiveness. In order to study the structural behaviour of a 20-storey building with vertical setback irregularity has been modelled and analysed by response spectrum method considering with and without Construction Sequence Analysis (CSA) using different structural systems in CSI ETABS V16 as per BIS 1893:2016 (Part 1). Finally, results such as axial force, shear force, bending moment are drawn for the structural members and response such as storey displacement, storey shear and storey drift are plotted and compared for each structural system.

Education is the vital parameter of the country for development in divergent areas like cultivation, economic, political, health and so on. Any educational Institute’s (universities, colleges, schools) main goal is to increase the student’s learning capabilities and their skills for their full contribution towards the society. In these days, “student’s learning process and skill development” research topic requires much needed attention for the betterment of the society. The student’s performance depends on his/her learning ability and is influenced by many factors. In this paper, we analyze the different categories of student’s leanings that are very fast, fast, moderate and slow. For this, we conducted the training and tests for attributes like ability, knowledge level, reasoning and core subject abilities for the 313 engineering students in AITAM, Tekkali, affiliated to JNTUK, India from 2017 to 2019. We gathered information about personal, academic, cognitive level and demographic data of students. In this experiment, we are conducting statistical analysis as well as classification of students into 4 types of learners and applying the different Machine Learning (ML) techniques and choose the best ML algorithm for predicting students learning rates. This leads to conducting the remedial classes with new teaching methods for moderate and slow leaning students. The proposed paper accommodates the individual differences of the learners in terms of knowledge level, learning preferences, cognitive abilities etc. For this, we apply 5 ML algorithms that are Naive Bayes, classification Trees (CTs), k-NN, C4.5 and SVM. As per ML analysis, the k-Nearest Neighborhood (k-NN) algorithm is more efficient than other algorithms where the accuracy and prediction values are nearer to 100%.

It is common practice to retrofit continuous reinforced concrete (RC) beams by fiber reinforced polymer (FRP) or steel plates. This can cause a significant amount of moment redistribution (MR) which results in an efficient and economic design when taken into consideration. There is lack in research regarding MR in continuous RC beams when strengthening plates are applied only at the top side at the hogging regions. The main purpose of this paper is to assess MR in continuous RC beams top strengthened with steel and/or carbon fiber reinforced polymer (CFRP) plates. In this respect, a nonlinear finite element model was developed using ABAQUS 6.14 and validated using experimental research program. The model was found capable of stimulating the behavior of such beams and hence assessing the percentage of MR which can be achieved using steel and CFRP strengthening. A parametric study is conducted to investigate the effect of various parameters, different from those investigated in the experimental program, on the MR in continuous RC beams. Parameters related to the concrete compressive strength, reinforcement ratio, beam thickness and thickness of strengthening plates were considered in this study. The results showed that significant amounts of MR can be achieved using either steel or CFRP plates and that MR is enhanced with the change in concrete compressive strength. Moreover, it was found out that the change in steel bars reinforcement ratio or in thickness of the strengthening plates has different effect on the beams strengthened with steel plates than those strengthened with CFRP plates.

Published: April 2020

Most virtual learning environment fails to recognize that students have different needs when it comes to learning. With the evolving characteristics and tendencies of students, these learning environments must provide adaptation and personalization features for adaptive learning materials, course content and navigational designs to support student’s learning styles. Based from the data mining results of learner behavioral features of five hundred seven (507) tertiary students, an accurate model for classification of student’s learning styles were derived using J48 decision tree algorithm. The model was implemented in a prototype using a framework and a proposed system architectural design of an adaptive virtual learning environment. The study resulted in the development of an adaptive virtual learning environment prototype where learner’s preferences are dynamically diagnosed to intelligently personalize the course content design and user interfaces for them.

Biometric Authentication is a security process that replays on the unique biological characteristics of an individual. Biometric Authentication system compare a biometric data capture to stored, confirmed authentic data in a database. It is simply the process of verifying the identity using the measurements or other unique characteristics of the body, then logging us in a service, device and so on. It is an effective way to prove identity because it can’t be replicated. Multi focus Image fusion is a process of fusing two or more images to obtain a new one. Used to reduce the problems like blocking, ringing artifacts occurs because of DCT. The low frequency sub-band coefficients are fused by selecting coefficient having maximum spatial frequency. The goal is classifying the images to classes of authorized and unauthorized using multi class SVM. The fingerprint image and iris image are fused together using SWT, the features are extracted from the fused image and labelled using GLCM algorithm. The testing image is then compared with trained samples and classified as authorized or unauthorized by using FFNN.

We present the case of a 54-year old woman diagnosed with chronic suppurative otitis media, who was admitted to the ENT Department with four-week-old, sudden-onset, left-sided facial nerve paralysis, and ipsilateral otalgia and hemicrania. Physical examination revealed positive signs of acute postaural inflammation. The patient’s facial nerve paralysis was scored as VI, according to the House-Brackmann scale. A cranio-facial computer tomography examination revealed mastoid cavity opacification, mucosal hypertrophy, and signs of chronic osteitis, with minimal mucous accumulation. The patient underwent a radical modified mastoidectomy with type-I tympanoplasty to verify the presence of a cholesteatoma, and to remove the offending lesions. Post-operatively, patient evolution was favorable, and prognosis remained encouraging. The patient’s evolution will be followed by check-ups every three months to assess progress and benefits of the treatment.

Published: April 2020

Aim. Study manifestations of epidemic process during acute intestinal infections to establish reasons of low effectiveness of the prophylactic measures carried out and evaluation of the role of rotavirus infection in general disease structure ofintestinal infections ofunknown etiology. Materials and methods. Data on morbidity of acute intestinal infections of population of Moscow were analyzed. Hospitalized patients with acute intestinal infections were examined using real-time PCR method test-systems of laboratory of molecular virology of Mechnikov RIVS with subsequent typing. Results. Evaluation of multi-year manifestations of epidemic process of morbidity of acute intestinal infections in Moscow has shown, that the cumulative morbidity does not have a tendency of reduction, because the proportion of infections with undeciphered etiological factors is almost 80% of the total aggregate morbidity. The proportion of rotavirus infection in total morbidity of AII of established etiology increased from 53.2 in 2004 to 82.6% in 2014. Morbidity in children with rotavirus infection is 6 times higher than morbidity in adults. Conclusion. The results obtained give evidence on the necessity of carrying out specific prophylaxis against viral intestine infection, mostly of rotavirus and norovirus infections. The highest effect should have been expected from use of a bi-vaccine, development of which seems quite an actual problem.

Published: April 2020

Aim. Study the role of LPS in induction of anti-tularemia immunity in humans and animals. Materials and methods. Activity of various antigenic preparations of tularemia microbe, including highly purified from protein and S- and R-LPS, was studied using leukocytolysis reaction with blood of vaccinated humans and guinea pigs and skin allergy test (guinea pigs). Results. Only the whole cells of Francisella tularensis, killed in protein non-denaturating conditions and conserving full S-LPS structure (tularin+) were shown to be inductors of delayed-type hypersensitivity reaction. Alterations in LPS structure (tularin) results in a significant decrease, and denaturation of bacterial proteins (during boiling) results in a complete loss of immune stimulating properties of the preparations. Purified LPS preparations and O-polysaccharide fraction of S-LPS are not able to activate cell-mediated immunity. Conclusion. The presence of LPS with the full structure affects the ability of antigenic preparations of F.tularensis to cause allergic reactions, and thus, form cell-mediated anti-tularemia immunity. LPS of F.tularensis can not be excluded as an adjuvant and provides the most effective presentation of epitopes of protein molecules for interaction with receptors of T-lymphocytes.

Papillomaviruses are a large and diverse group of viruses. It includes approximately 200 fully described types that have been detected in humans. Human papilloma viruses (HPV) are etiologic agents during various benign and malignant lesions of mucous membrane and skin epithelium. Very importantly, persistent HPV infection of certain types is a leading cause of carcinoma of uterine cervix, penis, vulva, vagina, anal canal and fauces (including tongue base and tonsils). HPV infection prophylaxis is the best means to control HPV-conditioned diseases, and vaccination, as had been demonstrated, - the most effective method of its prophylaxis. In this paper principle characteristics and clinical manifestations of papillomavirus infection, as well as effectiveness of vaccination against HPV are examined.

Aim. Study transformation of skin microflora during development of atopic dermatitis. Materials and methods. 45 patients with various forms of atopic dermatitis (AtD) were examined. Control group consisted of 26 healthy individuals. The strains were cultivated on elective nutrient media. Identification of the isolated strains was carried out by MALDI-TOF mass-spectrometry method. Results. A low frequency of occurrence of taxon Staphylococcus epidermidis on face skin and high frequency of occurrence of Staphylococcus aureus on upper and lower limb skin was established for AtD patients compared with healthy individuals. The frequency of occurrence of proteolytically active isolates of S. aureus in AtD patients was 3 times higher than in healthy carriers of this taxon. Taxons of microorganisms not inherent to healthy individuals such as Bacillus mycoides, Pseudomonas putida, Pseudomonas radiobacter were isolated on lower limb and neck skin of AtD patients. A high frequency of occurrence of Cryptococcus satoi, Candida albicans, Malassezia globosa fungi was noted. Conclusion. A decrease of barrier functions of skin during AtD facilitates contamination of patients’ skin with rare bacterial taxons and fungi. One of the possible mechanisms of suppression of immune competent cell functions could be proteolytic enzymes of S. aureus.

Aim. Study of mechanisms of attenuation of cold-adapted (ca) influenza virus strain A/ Krasnodar/101/35/59 (H2N2), associated with disruption of NS1 protein functions. Materials and methods. Study of interferonogenic activity of ca strain A/Krasnodar/101/35/59 (H2N2), its parent variant A/Krasnodar/101/59 (H2N2), virulent strain A/WSN/33 (H1N1) and a number of single gene and multiple gene reassortants between these strains, obtained using reverse genetics, was carried out. Study of dynamics of IFNp gene expression was carried out by using a methodical approach of RT-PCR in real time mode. Results. Inclusion of PB-1 gene of ca strain A/ Krasnodar/101/35/59 (H2N2) with reversion to wild type into genome composition of virulent strain А/WSN/33 (H1N1) does not result in a sharp change of interferonogenic activity of the reassortant. At the same time, similar inclusion of PB-1 gene of ca strain resulted in an incredible growth of interferonogenic activity of the reassortant. On the other hand, inclusion of NP-gene of wild type strain A/Krasnodar/101/59 (H2N2) into genome composition of the wild type strain А/WSN/33 did not differ by effect on interferonogenicity of the reassortant from inclusion of NP-gene of ca strain. Conclusion. Both constellations of genes of parent variants and mutations localized in these genes could affect formation of attenuation phenotype of reassortants. The data obtained allow to assume possible mechanisms of attenuation of ca strains, associated with disruption of NS gene function.

A fenilcetonúria é uma doença autossômica recessiva e indivíduos portadores de tal doença apresentam carência nutricional devido a dieta restritiva. O trabalho teve por objetivo, apontar as principais carências nutricionais em portadores de fenilcetonúria aderentes a dieta restritiva e verificar se há relação com o estresse oxidativo. Trata-se de revisão da literatura de aspecto descritivo, onde por meio dos descritores foram a priori selecionadas referências, que, após a leitura resultou em 27 utilizadas neste trabalho. Foram extraídos dados de 11 artigos referentes às seguintes comparações séricas entre fenilcetonúricos e indivíduos sadios: selênio, L-carnitina, coenzima Q10 e glutationa peroxidase (GPx). Dados de artigos referentes ao selênio, demonstraram diminuição em fenilcetonúricos, da mesma forma com L-carnitina e GPx, os quais em todos estudos houve redução sérica. Apenas a coenzima Q10 demonstrou uma divergência, com maior média em fenilcetonúricos aderentes a dieta. A exclusão de alimentos ricos em fenilalanina tem como consequência a carência nutricional, reduzindo a capacidade antioxidante, evidenciando a importância da adição destes nutrientes nas fórmulas alimentares de fenilcetonúricos ou a suplementação como tratamento coadjuvante à dieta restritiva.

A alimentação rápida demonstrou aumentar o risco de excesso de peso em crianças e adultos. Os objetivos do presente estudo foram investigar a correlação entre a taxa de mastigação e o número de mastigações por bocado e avaliar se elas estavam associadas ao peso da ingestão de refeições. Trinta indivíduos saudáveis, com idades entre 18 e 24 anos, fizeram um almoço de teste em sua velocidade habitual até sentirem-se saciados. As atividades dos músculos masseter e supra-hióideo foram registradas para determinar o número de mastigações e o momento da deglutição. O peso da ingestão de refeições foi registrado juntamente com o índice de massa corporal (IMC), taxa de mastigação, número de mastigações por bocado, duração da refeição, taxa de ingestão, fome e níveis de preferência alimentar. O peso médio (± DP) da ingestão de refeições, taxa de mastigação e número de mastigações por bocado foram 261,4 ± 78,9 g, 94,4 ± 13,5 mastigações mín.-1 , 19,2 ± 6,4 mastiga por bocado, respectivamente. A taxa de mastigação não se correlacionou com o número de mastigações por bocado. A regressão linear multivariável mostrou que a ingestão de refeições foi significativamente associada positivamente à taxa de mastigação, duração da refeição e IMC, mas inversamente associada ao número de mastigações por bocado ( R 2 ajustado = 0,42). Concluiu-se que o número de mastigações não estava associado à taxa de mastigação, mas a ingestão de refeições foi explicada tanto pelo número reduzido de mastigações quanto pelo aumento da taxa de mastigação.

The objective of this work was to evaluate the reaction of biomass and saccharin sorghum genotypes to a isolate of the Ramulispora sorghi. The experiment was conducted in a completely randomized design with three replications in a greenhouse. The variables analyzed were: area below the disease curve progress; lesion length (LL), lesions width (LW); normalized area below the curve of the lesion area expansion; incubation period and latency period. Data were submitted to analysis of variance, Pearson correlation and multivariate analysis based on Mahalanobis distance, using the Tocher and UPGMA clustering method. Significant differences were observed in the level of (p<0.01) and (p<0.05), for almost all variables analyzed. Of the 45 correlations, only 22 (48.89%) were significant by t-test, regardless of significance (p<0.01 or 0.05), where it was observed that in all significant correlations were positive, indicating that the reaction symptoms correlate between the variables evaluated. The groupings generated by the Tocher and UPGMA clustering method were in agreement to group genotypes with the same behavior in relation to reaction to Ramulispora sorghi. From the observed results, it was verified that all evaluated genotypes presented ramulispora spot symptoms, thus demonstrating their susceptibility to the pathogen.

The objective of this study was to know the profile of traumatic spinal cord injuries in Brazil. Thus, was used the integrative review, whose searches were conducted in October 2018, with health descriptors: spinal cord injuries, injuries and injuries, spinal injuries, epidemiology, spinal column and wheelchair. Among the data surveyed in the last 10 years, from January 2008 to January 2018, 148 publications were found in the Latin American and Caribbean Literature in Health Sciences (LILACS), 136 in the Medical Literature Analysis and Retrieval System Online (MEDLINE) and 85 in the Scientific Electronic Library Online (SCIELO), leaving only 10 articles after selection criteria. Therefore, the results showed that the profile of the patients affected by traumatic spinal cord trauma is of men, with low schooling and age between 21 and 30 years. In addition, there is a predominance of injuries caused by a car accident, fall and perforation by firearm projectile, mainly injuring the cervical and thoracic portions of the spine. Thus, it is concluded that the development of this study contributed to the understanding of the epidemiological profile, the main causes and the factors that are related to the injuries of the traumatic spinal cord trauma, and may contribute to the improvement of the care provided to this group.
Living Ubuntu: the struggles of Abahlali Base Mjondolo as an African philosophy in the making
Authors: Khosi Motlatsi
Published: April 2020

What does it mean to engage in a philosophy of struggle and emancipation in our South African context? As part of my MA research I took an internship with Abahlali BaseMjondolo, a shack dwellers’ movement whose office is based in central Durban. Their members reside in various settlements within KwaZulu Natal and the Eastern Cape. Whilst interning at the movement I conducted interviews with some of their members, using this experience to gain insight into the movement’s theory and philosophy. Here I was challenged by what it means to do research using narrative as the foundation of my work. It is through narrative that one can tackle the problematic representations of black people in academia and society. I argue that in this movement a philosophy is at work. Their philosophy is based on the lived experience of struggle. As producers of knowledge, I argue that they represent the workings of Ubuntu. Using Maboge B. Ramose’s (2002) explanation of ‘Ubuntu as philosophy’ I show how it can help us understand what it means to be human and how this is being affirmed in spaces of struggle. As agents of struggle we (black people) must be recognised for how we create knowledge. Ubuntu becomes the means through which we can map out the ways in such recognition can be understood and which an African philosophy is being being practiced. It is this recognition that is at the heart of the movement’s philosophy of ‘Abahlalism’ which demonstrates the complexity of black experience in the space of social movement struggles.Key words: SOTL, scholarship of teaching and learning, Ubuntu, African philosophy, decolonial theoryHow to cite this article:Khosi, M. 2020. Living Ubuntu: The struggles of Abahlali Base Mjondolo as an African philosophy in the making. Scholarship of Teaching and Learning in the South. v. 4, n. 1, p. 26-36.

Emerging response-abilities: a reflection on the 2019 SOTL in the South conference
Authors: Cullinan Cook Shashi
Published: April 2020

The second biennial ‘SOTL in the South’ conference was held at the Central University of Technology (CUT) in Bloemfontein, South Africa, in October 2019. Scholarship of Teaching and Learning (SOTL) is gaining increasing traction in South African universities, and this conference was a collaboration between the Centre for Innovation in Learning and Teaching at CUT, and SOTL in the South. The theme of this conference was ‘Creating space for Southern narratives on Teaching and Learning’ and the keynote speakers were Boaventura de Sousa Santos, Joanne Vorster, Sabelo Ndlovu-Gatsheni and Catherine Manathunga. In this piece I reflect on the conference and identify some of the narratives that emerged from it. I share some of the discussions by keynote speakers and presenters which help to expand discourses on the interconnectedness of decolonisation, and economic, social and environmental justice, and I explain why I look to ‘Southern SOTL’ for guidance in negotiating contradictions in my teaching and learning context. In this piece I consider the response-abilities of higher educators to contribute to these urgent matters.Key words: SOTL in the South, research in teaching and learning, global South, north-south, decolonisation, 4IR, fourth industrial revolution, response-abilityHow to cite this article:Cullinan Cook, S. 2020. Emerging response-abilities: a reflection on the 2019 SOTL in the South conference. Scholarship of Teaching and Learning in the South. v. 4, n. 1, p. 69-85.

Authors: Kamath Madhusudhana
Published: April 2020

Ayurveda is a traditional healing method in India for more than 5000 years, preserved from ancient pieces of literature, namely Atharva Veda. Ayurveda is believed and practiced commonly in India to promote robust human life and eliminate diseases as a person can maintain balanced constitutions which are called Tri-Dosha. The method is especially present in the practice of traditional medicines and is used to prescribe certain forms of treatment upon particular diseases. As such, herbal and related drugs are those of the most important parts mentioned in the traditional Ayurvedic texts. Despite their curing potential claimed in the texts, many cases now have been reported poisoned due to the use of these drugs. In the scope of our paper, the study would unveil the picture of the practice of Ayurvedic medicines nowadays and entail some answers for the reasons of drug poisoning.
Current problems of utilization of natural resource potential of territorial communities in Ukraine in the conditions of decentralization
Authors: Popadynets Nazariy , Leshchukh Iryna
Published: April 2020

Under the current processes of consolidation of territorial communities, the policy of their social, economic and ecological stability based on efficient nature management is related to the condition and nature of the use of natural resources by people in their activity to maintain their existence. Conducting economic activity, people use various natural resources. Therefore, objective and distinct assessment of natural resources is of particular importance. The development of a territory and entities located there depend on this assessment. Natural resources capacity is considered in modern science as the most important factors of economic development of both the regions and the country in general. The paper aims to research the problems of the use of natural resources capacity of a territorial community and to define the ways of their efficient use. Scientific approaches to classification of natural resources capacity of a territorial community are systematized and its nature is outlined. The structure of natural resources capacity of territorial communities is formed. Main problems of the use of natural resources capacity of territorial communities are defined. Conceptual and structural model of natural resources capacity of a territorial community is characterized. Major aspects of forming of modern financial-economic mechanism of capitalization of a community’s natural resources are examined. The paper reveals that natural resources capacity of territorial communities provides an opportunity to improve the level of financial capacity of a community by filling local budgets through the development of relevant territories. The approaches to the improvement of the efficiency of the use of natural resources by territorial communities in conditions of authorities’ decentralization in Ukraine are suggested.
