Este trabalho objetiva potencializar as discussões acerca dos saberes e conhecimentos da cultura afro-brasileira deliberadas pela lei n.10.639/03 (BRASIL, 2003). Trouxemos os apontamentos de como se dá essa ação na prática cotidiana escolar a partir do olhar dos professores de uma escola pública. Caracterizada como uma pesquisa do tipo qualitativa, por meio de um estudo de caso, na qual inserimos análise documental, entrevistas e acompanhamento dos docentes envolvidos. Os dados realçaram a necessidade de se repensar o campo da formação inicial. Os participantes demostraram insegurança e falta de autonomia para com as temáticas que tratam da religiosidade da cultura afro-brasileira, realçando a necessidade de se (re)pensar o processo de formação continuada.
A VERY SHORT INTRODUCTION TO DIGITAL ARCHAEOLOGY
Authors: Schoueri Kelly Marie Gillikin , Ferreira Lucio Menezes
Published: October 2020

Visual reconstructions of archaeological sites and materials have been around since before the formal construction of archaeology as a discipline itself. However, there has been an expansion of the methods of reconstructing and representing the past in the last decades due to the use of digital technology. 3D modelling of archaeological sites and artifacts can generate aesthetically pleasing visualizations, but there is a danger of over-exaggerating or decontextualizing the past for public audiences. As digital artists and archaeologists, we should use caution with creating and disseminating archaeological visualizations. Considerations for scientific accuracy, ethics and educational value need to be taken into account.  Therefore, this article introduces some of the theoretical issues involved with the digital reconstruction as well as an overview of the practical process of performing science-based archaeological 3D reconstructions and visualizations.

Published: October 2020

O trabalho objetiva desvelar a parceria público-privada realizada entre o município de Campo Grande e a Organização Mundial para a Educação Pré-Escolar (OMEP) que se efetivou ao longo de 41 anos. Trabalhou-se com a legislação, documentos oriundos do Ministério Público do estado de Mato Grosso do Sul e com a imprensa local. A parceria se encerrou em 2017, por determinação judicial, e ex-prefeitos foram penalizados. As implicações para a política de educação infantil no município que resultaram da parceria remetem à reprodução da desigualdade social e à manutenção do status quo das elites políticas locais.
On the capitalisation of schools in England
Authors: Glenn Glenn Rikowski
Published: October 2020

This article outlines some ideas that can be used in a project of educational subversion that seeks to relate particular educational phenomena to the constitution of capitalist society. These phenomena are elements of what I have previously (RIKOWSKI, 2003b; 2005c) called the ‘business takeover of schools’. Indeed, I have never really provided a sustained account of what I mean by this term, and how it relates to other concepts such as privatisation and commodification. Thus, I shall do so now in the context of certain developments in the schools system in England – which has been an interest of mine since 1997.
A atuação do setor privado no planejamento e na execução das políticas sociais: implicações para a democratização educação
Authors: Vera Maria Vidal Peroni  , Elma Júlia Gonçalves de Carvalho
Published: October 2020

É com satisfação que trazemos a público mais um número da Revista Teoria e Prática da Educação (RTPE), que, assim, mantém a adequada periodicidade e cumpre a importante função de socialização de pesquisas realizadas no campo educacional por autores estrangeiros e brasileiros.
Este número é dedicado a um dossiê contendo artigos sobre a redefinição do papel do Estado e das fronteiras das relações entre o público e o privado no planejamento e na execução de políticas sociais, bem como sobre suas implicações para a democratização da educação. Tais artigos contribuem para a compreensão de que as mudanças nas fronteiras entre o público e o privado são parte do novo contexto de crise do capitalismo mundial atual, marcado, sobretudo, pela expansão e pelo fortalecimento do capital financeiro e pela globalização/mundialização da economia. Considera-se que, nesse novo contexto, o neoliberalismo, a terceira via, o neoconservadorismo e a flexibilização produtiva impulsionam a redefinição do papel do Estado, com profundas consequências para a democratização da educação.
Em comum, os autores destacam as inúmeras inciativas de privatização da educação pública em curso no Brasil e na América Latina, alertando, igualmente, para seus efeitos. Evidenciam a tendência de transformação da educação em um campo propício para os negócios privados e que, segundo uma lógica mercantil, os interesses privados com ou sem fins de lucro têm influenciado ou definido a formulação de políticas, a gestão, o currículo das escolas, as condições de trabalho e a formação de professores.

Authors: Feitosa Osmiriz LIma , Selma Suely Baçal de Oliveira
Published: October 2020

Diante do processo de privatização da educação em tempos de neoliberalismo, buscou-se estudar os efeitos da proposta pedagógica curricular nas escolas do município de Boa Vista-RR. O objetivo é analisar a Proposta Pedagógica Saber Igual-PPSI, identificando que as atividades desenvolvidas nas escolas estão ajustadas a mercantilização da educação. Fundamentou com base em autores como Saviani (2011), Marx (2017) e Mészaros (2008). A metodologia utilizada foi de natureza bibliográfica com literatura da Pedagogia Histórico-Crítica – PHC de Saviani (2011), de natureza documental analisando a Proposta Pedagógica Saber Igual - PPSI e de natureza empírica através de entrevistas com professores da rede municipal. Os resultados revelam que a proposta contribui para privatização do currículo, revelando que a atividade docente está estruturada na tendência liberal/tradicional/tecnicista, pois os professores são meros executores do conteúdo programático.

Authors: Cossetin Márcia , Vanessa Pilarski
Published: October 2020

O artigo objetiva o estudo do Pacto Nacional pela Alfabetização na Idade Certa – PNAIC e busca a compreensão das intencionalidades deste como Política Educacional. O problema de investigação concentrou-se no questionamento: “Quais as intencionalidades do PNAIC para a educação no Brasil?”. A pesquisa caracteriza-se por uma abordagem qualitativa, com investigação documental e bibliográfica, em que foram utilizadas fontes primárias e fontes secundárias, fundamentadas em estudiosos da temática na atualidade. Inicialmente, contextualiza-se a história das políticas de alfabetização no Brasil, para então avançar ao objeto de pesquisa – o PNAIC. Conclui-se que o PNAIC foi uma política importante, que procura agir de forma a garantir o acesso à alfabetização. Todavia, no contexto em que a Política de Avaliação da Educação Básica - SAEB é central, preocupa-se mais com indicativos quantitativos, se comparados à qualidade do ensino e, assim, torna-se um programa viável para atender às necessidades de aumento dos índices de alfabetização.
Collision and Contact Sport Participation and Quality of Life Among Adolescent Athletes
Authors: Howell David R. , Kirkwood Michael W. , Laker Scott , Wilson Julie C.
Published: October 2020

Context

Researchers investigating collision and contact sport participation during high school have found mixed results. Understanding the association between current contact and collision sport participation and quality-of-life outcomes can enhance our knowledge about the risks and benefits of sport participation.

Objective

To examine quality-of-life outcomes among high school athletes who reported participation in collision and contact sports in the year preceding assessment compared with no- or limited-contact sport athletes.

Design

Cross-sectional study.

Setting

Preparticipation physical examination.

Patients or Other Participants

High school athletes 13 to 18 years of age.

Main Outcome Measure(s)

We obtained sport participation and Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric-25 outcomes, which assess self-reported, quality-of-life domains in the preceding 7 days (ie, state assessment). Our grouping variable was collision and contact versus no- or limited-contact sport participation during the year preceding assessment. We used multivariable linear regression models to identify the associations between PROMIS scores and collision and contact sport participation and adjusted for sex; age; history of bone, muscle, ligament, or tendon injury; history of acute fracture or dislocation; and history of concussion.

Results

A total of 143 (51%) athletes reported collision and contact sport participation (24% female, mean age = 15.1 ± 1.7 years) and 138 (49%) reported no- or limited-contact sport participation (66% female, mean age = 15.4 ± 1.2 years). A higher proportion of collision and contact sport athletes reported a history of time loss for bone, muscle, ligament, and tendon injuries (51% versus 29%, P < .001) and for acute fracture or dislocation (46% versus 26%, P < .001) than did no- or limited-contact athletes. After adjusting for covariates, we found that collision and contact sport participation was significantly associated with lower state anxiety (β = −1.072, 95% confidence interval = −1.834, −0.310, P = .006) and depressive (β = −0.807, 95% confidence interval = −1.484, −0.130, P = .020) symptom scores.

Conclusions

Collision and contact sport athletes reported fewer anxiety and depressive symptoms in the week preceding evaluation than did no- or limited-contact sport athletes, but they had more extensive orthopaedic injury histories. Potential benefits and risks are associated with collision and contact sport participation. These data reinforce the need to examine the assumption that youth collision and contact sports are associated with negative quality of life.
Substance use amongst high school learners in the south of Johannesburg: Is this the new norm?
Authors: Mohale Debrah , Mokwena Kebogile E.
Published: October 2020

Background: Substance use amongst high school learners is common in South Africa, with related risky behaviours and outcomes. Because of the social and geographical trends, studies in various parts of the country are essential to contribute to the understanding of the overall picture. The purpose of this study was to determine the prevalence of substance use, as well as the factors associated with substance use in a sample of high school learners in a suburb south of Johannesburg.Methods: A quantitative cross-sectional survey, by using a self-administered questionnaire, was conducted amongst 308 learners in four high schools. The parents of all the learners provided consent for their children to participate in the study.Results: The sample consisted of 308 learners who were in grades 8–12, with a mean age of 16.3. The majority (57%, n = 177) were females and 43% (n = 131) were males. The prevalence of substance use was 31% (n = 94), with 52% (n = 49) of those who use substances being male, compared with 48% (n = 45) females. Of those who used substances, 69% (n = 65) used alcohol, 10% (n = 9) smoked dagga, 5% (n = 5) smoked cigarettes, 7% (n = 7) used other substances and 46% (n = 43) were polyusers. Age, missing school because of illness, use of leisure time and friends using substances were significantly associated with the use of substances (p 0.05).Conclusion: The prevalence of substance use was high at 31%, which is of concern because the use of legal psychoactive substances remains illegal for minors. The risky factors associated with the use of substances highlight the threat that this behaviour has on the social well-being and educational outcomes of the learners.
Double trouble: A case of synchronous presentation of acute myeloid leukaemia and multiple myeloma
Authors: Mashigo Nomusa
Published: October 2020

Malignancies following successful chemotherapy for various malignant diseases, including multiple myeloma (MM), are well known and documented. The occurrence of acute myeloid leukaemia (AML) after chemotherapy for MM with alkylating agents is well described; however, simultaneous occurrence of the two entities with no prior therapy is extremely rare. We describe a case of an elderly patient with no previous exposure to chemotherapy, who was diagnosed with both MM and AML concurrently. Very few similar cases have been described in the literature.

Authors: Khan Aafreen , Singh Shashank N. , Ali Tauseef , Palod Sahaj , Ojha Ridhima , Mahendran C. , Bhandari Virendra
Published: October 2020

Aim of Study:

The aim was to assess the potential reduction in the doses to organs at risk (OARs) and target organ volume by doing replanning on repeat computed tomography (CT) scan during the 4th week of radiation therapy (RT).

Materials and Methods:

Twenty-four histologically proven patients of inoperable esophagus carcinoma were studied. All patients received induction chemotherapy followed by concurrent chemotherapy and radiotherapy. CT simulation with proper immobilization was done, and images were transferred to the treatment planning system. Delineation of target volumes and OARs was done, and two plans were generated for 60 Gy in 30 fractions and 40 Gy in 20 fractions with intensity-modulated RT keeping the doses to OARs within the tolerance limits. Replanning for 20 Gy in 10 fractions was done on repeat CT scan during the 4th week of radiotherapy treatment, and potential reduction in doses to OARs and target organ volume was assessed.

Results:

A total of 24 cases were analyzed for the adaptive plan with the coverage of the 95% prescription isodose for planning target volume. Statistical analysis was done by t-test. The difference in the doses received by the OARs was analyzed and was seen that due to re CT scan, the doses were reduced to the left lung V
20 (mean 19.23 Gy vs. 17.35 Gy) and D
mean (mean 16.03 Gy vs. 14.25 Gy), right lung V
20 (mean 18.38 Gy vs. 16.66 Gy) and D
mean (mean 15.70 Gy vs. 13.97 Gy), heart V
25 (mean 38.72 Gy vs. 35.32 Gy) and D
mean (mean 26.40 Gy vs. 22.74 Gy), and spine 1% volume (mean 36.54 Gy vs. 33.39 Gy) and D
max (mean 39.81 Gy vs. 34.34 Gy), gross tumor volume (GTV) (mean 67.37 cm 3 vs. 24.58 cm 3) and were all significantly smaller for the adaptive plan.

Conclusion:

By doing adaptive radiotherapy in the 4th week of treatment using repeat CT scan, along with the response evaluation, there is a significant reduction in the volume of GTV, and replanning of treatment on repeat CT scan also helps us in reducing doses to the OARs resulting in reduced toxicity.

Published: October 2020

Purpose:

The study was done to evaluate the role of adjuvant therapy in curatively resected Stage II and III gallbladder carcinoma (GBC).

Materials and Methods:

This was a retrospective analysis of patients of GBC registered between 2008 and 2017 in outpatient department of a tertiary cancer hospital in India. Patients who had any of the following adjuvant treatment after radical surgery: (a) external beam radiotherapy (RT) alone, (b) chemotherapy (CT) alone, and (c) RT with CT (CRT) were considered for the study.

Results:

A total of fifty patients could meet the selection criteria. It was seen that seven patients were treated with RT, 20 with CT, and 23 with CRT. Median follow-up for patients who were alive was 26.7 months. Nineteen patients had locoregional failure while eight had distant failure. Patients treated with CRT had a significantly better mean overall survival compared to those treated with RT or CT (44.0 months, 12.5 months, and 15.1 months, respectively; P = 0.003). Similarly, mean disease-free survival was superior in CRT arm compared to RT and CT arms (43.6 months, 9.6 months, and 12.4 months, respectively; P = 0.002).

Conclusions:

Adjuvant CRT had better survival outcome compared to patients treated with either RT or CT with Stage II and III disease after curative cholecystectomy.
Systemic treatment options for growing teratoma syndrome
Authors: Acikgoz Yusuf , Bal Oznur , Ergun Yakup , Oksuzoglu Berna , Yildiz Birol , Doğan Mutlu
Published: October 2020

Background:

Growing teratoma syndrome (GTS) is a very uncommon phenomena. Given its lower prevalence, there is little data about clinichopathological features and management of GTS. Literature about disease mostly composed of case reports. In this study, we aimed to report patients characteristics and treatment modalities in our center within a relatively large cohort.

Patients and Methods:

We retrospectively reviewed the clinical records 21 patients who fulfilled criteria of GTS. Survival analysis was performed by using the Kaplan-Meier method with the Long-rank test. p<0.05 was considered statistically significant.

Results:

The median age at diagnosis was 25 (range 17-51). A total of 12 patients could have undergone surgery. Of patients who underwent surgery, 5 patients remained fully disease free, and 7 patients had experienced disease recurrences. Nine patients had unresectable disease, and treated with either platin-based chemotherapy or interferone α2b. Of those, 5 patients eventually had undergone autologous stem cell transplantation (ASCT) with surprisingly promising response rates. One patient had complete response and three patients had partial response. One patient died soon after ASCT due to infectious complication.

Conclusion:

GTS is an unique entity with regard to its clinicopathological features and available treatment options as we mentioned in the text. Despite various agents reported to have efficacy in case reports, surgery remains as the mainstay of treatment. According to result of our study, ASCT and platin-based chemotherapy regimens may be feasible options for patients with unresectable disease.
Autocorrelation functions for quantum particles in supersymmetric Pöschl-Teller potentials
Authors: Cellarosi Francesco
Published: October 2020

We consider autocorrelation functions for supersymmetric quantum mechanical systems (consisting of a fermion and a boson) confined in trigonometric Pöschl–Teller partner potentials. We study the limit of rescaled autocorrelation functions (at random time) as the localization of the initial state goes to infinity. The limiting distribution can be described using pairs of Jacobi theta functions on a suitably defined homogeneous space, as a corollary of the work of Cellarosi and Marklof. A construction by Contreras-Astorga and Fernández provides large classes of Pöschl-Teller partner potentials to which our analysis applies.
Поправки конечного размера к скейлингу свободной энергии в модели димеров в шестиугольной области
Authors: Nazarov Anton Andreevich , Paston Sergey Aleksandrovich
Published: October 2020

Рассматривается модель димеров на шестиугольной решетке. Эту модель можно представить в виде "кучи кубиков в углу коробки". Энергия конфигурации дается суммарным объемом кубиков. Статистическая сумма модели вычисляется по классической формуле Макмагона или как детерминант матрицы Кастелейна. Формула Макмагона используется для вывода скейлингового поведения свободной энергии в пределе, когда шаг решетки стремится к нулю, а температура стремится к бесконечности. Рассматриваются случай конечной шестиугольной области, случай, когда длина одной из сторон шестиугольника стремится к бесконечности, и случай неоднородных весов Больцмана. Получено асимптотическое разложение свободной энергии, которое обычно называется поправками конечного размера. Обсуждаются универсальность и физический смысл коэффициентов этого разложения.

Authors: Naz Tayyaba , Shamir Muhammad Farasat
Published: October 2020

В контексте модифицированной $f(\mathcal G)$-гравитации исследуется возникновение анизотропных компактных звездных объектов. Геометрия пространства-времени характеризуется метрическими потенциалами, и для решения полевых уравнений рассматривается их специальный вид, который известен как пространство-время Толмана-Кучовича. Полученные решения свободны от сигулярностей и удовлетворяют всем требованиям, предъявляемым к звездным объектам. Рассмотрены данные наблюдений для моделей звезд Cen X-3, EXO 1785-248 и LMC X-4, и с учетом этих данных получены значения физических параметров из условий сшивки внутреннего пространства-времени Толмана-Кучовича с внешней метрикой Шварцшильда. Кроме того, обсуждаются некоторые физические характеристики анизотропных компактных звездных структур с целью проверки физической обоснованности и устойчивости предложенной модели. Проведен трехмерный графический анализ, позволяющий получить представление о физическом поведении этих компактных объектов. Замечено, что все три компактных объекта соответствуют физически принятым моделям.

Published: October 2020

Dans le but d’analyser la contribution du poulet indigène à la génération des revenus et à la sécurité alimentaire dans un ménage, une enquête longitudinale d’une année a été réalisée dans 45 exploitations avicoles du Département de Salémata (Sénégal). Les résultats ont montré que les effectifs de poules sont passés de 17,1 à 23,4 poules. Les causes les plus importantes de variation des effectifs des poules dans un ménage ont été la consommation (25,5%), les ventes (31,22%) et les pertes (38,68%). Les pertes ont été causées en grande partie par les rapaces (21,61%) et les chats (65,80%). Quant aux circonstances de consommation des poules, les plus importantes ont été les festivités religieuses (37,97%) et de fin d’année (26,06%) ainsi que les consommations domestiques (14,34%) ou d’accueil d’un hôte (11,52%). Les oeufs pondus (10,2) sont presque tous couvés (10,1). Les taux d’éclosion et de mortalité des poussins ont été de 81,36% et de 47,11%. Le rapport profit sur investissement,  consommations internes du ménage incluses, a été de 4,05. Les  consommations moyennes annuelles d’oeufs et de poules par ménage ont été de 56,7 oeufs et de 48 poules dans un ménage de taille moyenne de 7 personnes. Il ressort de cette étude que l’aviculture familiale constitue un moyen d’amélioration de la sécurité alimentaire et d’atténuation de la pauvreté. Des recherches doivent être faites pour améliorer la protection des poussins, l’alimentation et la santé des oiseaux.Mots clés : Aviculture familiale, sécurité alimentaire, lutte contre la pauvreté, socio-économie, Sénégal. English Title: Socio-economic importance of family poultry in SenegalA one-year longitudinal survey was carried out in 45 poultry farms in Salémata Department (Senegal) to show the contribution of family poultry to poverty alleviation and food security in a household. The results showed that chicken numbers increased from 17.1 to 23.4 hens. The most important causes of variation in hen numbers in a household were  consumption (25.5%), losses (38.68%) and sales (31.22% hens). The most frequent causes of mortality were predators (Raptors: 21.61% and cats: 65.80%). The most important circumstances of consumptions were religious holidays (37.97%) and year-end (26.06%), the household (14.34%) or to welcome a host (11.52%). The eggs laid (10.2) are almost all incubated (10.1). The hatching rate and chicks' mortality were 81.36% and 47.11%, respectively. The return (profit/investment) with family consumption was 4.05. The average annual consumption of eggs and chickens per household was 56.7 eggs and 48 chickens in a household size of 7 people.

This study assessed the effects of social media on researchers’ work attitude at IITA, Ibadan, Oyo state, Nigeria. Proportionate sampling technique was used to select 82 respondents for the study through the use of questionnaire. Data collected were analysed using percentage, Chi-square and Pearson Product Moment Correlation (PPMC). Results showed that the frequently used media on a daily basis, were emails (87.7%), Facebook (76.6%) and WhatsApp (71.6%) while Skype (24.7%) and Twitter (21.0%) were used on weekly basis. Researchers used social media to source for journals (14.8%), collaborative research (38.2%) and connection with families and friends (41.9%) as well as for online dating (7.4%). Furthermore,  38.0% of the respondents accessed social media from their departmental office, personal office (29.7%) and their individual homes (13.6%).  Researchers agreed that social media were essential office tools (37.0%), retarded their work (3.7%) as well as wasted their time (1.2%). Chi-square  analysis showed that there was significant relationship between the usage of social media and religion (χ 2=8.336, p≤0.05), marital status (χ2=14.81, p≤0.05) and rank/cadre of respondents (χ 2 =23.03, p≤0.05) while PPMC analysis results showed a significant relationship between social media  usage and age (R = -0.245, p≤0.05) as well as work experience (R= -0.33, p≤0.005). Social media has both positive and negative effects on  researchers’ attitude to work. Social media usage should be controlled during working hours to improve the positive attitude of researchers  towards work at IITA.

Adoption of good agricultural practices by cattle farmers in the Binh Dinh Province of Vietnam
Authors: Hoang Gia Hung
Published: October 2020

This study examined factors that affect the adoption of good agricultural practices (VietGAP) by Vietnamese beef cattle farmers. A random sample of 305 farmers was drawn from a total of 1279 farmers who produced and marketed beef cattle in the Binh Dinh province of Vietnam. Percentages, means, standard deviations, chi squares test, t-test and binary logistic regression model were employed to analyse the data. The study found that the young farmers with a higher education level, who had a large number of cattle, possessed a large farm, owned ICT tools for marketing, participated in credit and training programs, had a high income and communicated with extension officers, had a greater tendency to adopt VietGAP. Improving education, providing technical training and credit services, promoting the farmers’ use of ICT tools for marketing and developing agricultural extension services for livestock farmers is a way to facilitate the adoption of VietGAP by farmers.

The Nagorno-Karabakh Conflict between Azerbaijan and Armenia from the Historical Perspective
Authors: DİYARBAKIRLIOĞLU Kaan
Published: October 2020

The Nagorno-Karabakh problem had continued for years. The problem had grown thanks to the policies of Russia in the region. The Russians first had carried out expansionist policies. After the industrial revolution, oil in the Caucasus had gained importance in the region. Therefore, the Russian Armenians immigrated to these regions. Strategic plans have been developed to increase the Christian population in the region and to make the region a region without Turks. Armenia and Azerbaijan had gained independence after the Soviet Union collapsed after the Cold War. After the Soviet Union, Russia had given the region the right to self-determination, and the population in the Nagorno-Karabakh region began to be Armenian. Azerbaijani Turks were immigrated from this region. Negotiating groups have been included for the solution of the problem in this region and a ceasefire has been signed between the two countries. Violations had occurred over the years after the ceasefire signed between the two countries. Russia had not wanted the presence of international actors in this region. For this reason, Russia continues to be on the Armenian side. Today, Russia has a voice in the region with a balanced policy. Nagorno-Karabakh region is legally connected to Azerbaijan and has not been recognized as de-facto.

Improving the Efficiency of Hybrid Boundary Element Method for Electrostatic Problems Solving
Authors: Peric Mirjana , Ilic Sasa , Vuckovic Ana , Raicevic Nebojsa
Published: October 2020

This paper describes a modification of the Hybrid Boundary Element Method (HBEM) for electrostatic problems solving. Such improved method is applied for transmission lines analyses. By taking a quasi-static TEM approach, the Hybrid Boundary Element Method is applied to determine the effective relative permittivity and the characteristic impedance of different stripline structures. Comparisons with already published numerical results and software simulation have been also performed with an aim to test the validity of the proposed approach. A close results match can be noticed. The main novelties of the proposed HBEM modification are better accuracy and ability to determine the polarization charges distribution on the separating surface between a strip and a dielectric layer. This was not possible before, using the previous version of the method.

Organic farming is a holistic agricultural system that enhances soil quality. Amaranth viridis is a popular a nutritious leaf vegetable that contain gluten-free grain which provides plenty of fiber, proteins and micronutrients which is used in herbal medicine. An organic fertilizer called Jeevamrutham is developed by using cow dung, cow urine, jiggery and pulses flour. Application of this fertilizer Amaranthus fields enhanced the physicochemical properties of the soil such as pH, EC, N, P, K, and organic carbon content. Microbes such as Azospirillum and Actinomycetes are enhanced in experimental soil. The quantity of phytohormones like indole acetic acid, Gibberlic acid, Abscisic acid and kinetin are also increased. In total there is an increase in biomass, shoot length and root length in Amaranthus Viridis plant with Jeevamrutham. Thus, Jeevamrutham can be efficiently used organic fertilizer to improve growth and development and yield of Amaranthus Viridis.
An Exploratory View on Congregating God and Science through Variegating Perspectives
Authors: N. R. Mr. Jaswin Kumar
Published: October 2020

Science is often associated with atheistic ideologies. The field of science is thought to be as one of the disciplines, wherein only rational and logical theories are often applicable. Moreover, anything that cannot be explained in terms of logical scientific theories or formula is termed as supernatural or irrational. This has also created a stereotypic notion among people that whoever is a patron of scientific ideas ought to be an atheist. Some scientists have been a fuel to this stereotype by openly embracing atheism. Furthermore, rationalism has gotten us far in the field of science. However, the ground reality is that the answers to seemingly impossible-tosolve questions cannot be discovered with logic alone. Hence, we refuse to believe in something, which is not scientific. Also, we may consider things, which we think as „beyond science‟ to make further developments within it. The reason being, it enables the mind to embrace creativity and look at various possibilities from different perspectives. This perspective of scientific thinking might even help us to resolve paradoxes and provide answers to questions like „Does God Exist?‟ Keeping these aforementioned notions, this conceptual paper overlooks on scientific theories with an exploratory view from a variegating perspective by substantiating the „String Theory‟ concepts to understand the possibility of existence of higher dimensions (up to 10th dimension) and facilitates to explain the existence of God.

Today, in power systems the Load Frequency Control (LFC) problem plays a vital role in an interconnected power system, wherein it maintains the system frequency and tie line flow at their scheduled values during normal period. It is due to frequency of power system, which changes over time with respect to continuous load variation. The present chapter proposes a new methodology to study the Load Frequency Control (LFC) problem of a three area inter-connected system using R Fuzzy system (FS) approach. Moreover, this technique is applied to control the systems which include three areas considering a non-linearity Generation Rate constraint (GRC) having two steam turbines and one hydro-turbine tied together. The main advantage of this controller is its high insensitivity to large load changes and plant parameter variations even in the presence of non-linearity. Furthermore, it is tested on a three-area power system to illustrate its robust performance. The results obtained by using Rule Based Fuzzy PID controller explicitly show that the performance of this proposed controller is superior to conventional controller in terms of several parameters like overshoot, settling time and robustness.

Many of the agricultural plots within Trinidad and Tobago remain in a state of dormancy due to a critical lack of infrastructure needed for their development. This has contributed to the increasing food import bill which was some TT$5.6 billion over the last couple of years. This overall crop irrigation project aims at assisting the farmers in setting up a proper infrastructure that will utilize natural resources. The lack of pipe water will be substituted by rainwater capture, storage and distribution via drip irrigation. The lack of power for water distribution by irrigation will be obtained by the use of solar power for the pumps. The project will be done in phases. This phase involved at creating a smart estimator to determine the water requirement and the planting land area for the 2-acre plot when the number of plants, type of plants, and the month in which the farmer chooses to start planting are chosen. It will estimate the water storage volume required for the various crops chosen based on the rainfall patterns, crop cycle and the crop water requirement. These output estimates will be based on the land area input, estimated water storage size, estimated tool shed size and produce storage area, and the type or types of crops chosen to farm by the farmer for the plot. The input parameters in the estimator can then be varied by the farmer, to help find an estimated or optimum balance of the number and type of crops, the planting land area, and the water captured and stored, based on the rainfall patterns and the unused land area. The outputs required can be similarly obtained through the use of existing models and software packages, but the tools are not ‘Farmer User Friendly and readily available’.

In a developing country like India with scarce hydrocarbon reserves and also due to variable nature of Renewables in terms of potential, penetration and technology, Coal must be relied upon as a source of energy in near future also, to meet the ever-growing demand for an instant form of energy i.e. Electricity. An alternative to not so clean source Coal appears to be Nuclear Power and this option can supplement and supplant our energy needs despite several concerns from various sources post-Fukushima Nuclear accident. This paper carries out a detailed LCA study of Nuclear based Electric Power Generation System with a wider scope that encompasses the waste disposal and spent fuel reprocessing phases, is modelled and run on SimaPro 9.0.0.48 LCA software with ECOINVENT 3.0 as database. This study also covers the all-important Inventory Analysis for the inputs used, raw material extracted and residuals consequently released to the environment. The results are expressed in terms of pre-defined energy metrics such as ERR and EPBT. Further, the study covers the environmental impact assessment category such as GWP and finally the results are presented with a kWh of electricity produced by this option as a functional unit. These investigations help energy planners and policymakers to compare various power generating options and justify the alternatives to meet future demand for electricity in a cleaner and more sustainable manner by keeping the spirit of Paris Climate Agreement in mind.
CONVECTIVE HEAT TRANSFER ON STENOSED BLOOD FLOW THROUGH PERMEABLE MICROCIRCULATION IN THE PRESENCE OF A MAGNETIC FIELD
Authors: Sankar Alana , Rao Gunakala Sreedhara , Comissiong Donna
Published: October 2020

Blood flow through permeable microcirculation in the presence of a composite stenosis, an external magnetic field and convective heat transfer was examined. A two-layered model for the blood consisting of a fluid-particle suspension in the core region with a peripheral cell-free plasma layer was used. The proposed system of equations was solved and plots were generated. In the presence of permeable walls, an external magnetic field and convective heat transfer, the temperature of the blood, friction-factor Reynolds number and Nusselt number were investigated. The temperature of the blood increased when the Hartmann number increased, Darcy number increased, haematocrit level increased or the peripheral layer thinned. The friction-factor Reynolds number product increased as the haematocrit, Hartmann number, stenosis height or Darcy number increased. The Nusselt number decreased as the Hartmann number, haematocrit, stenosis height or Darcy number increased. These results were interpreted in terms of the physical situation. This study aids in understanding the effects of wall permeability, a magnetic field and the presence of heat transfer on different diseased arterial systems in the future.

Este ensaio analisa a expressão da emoção na entoação do português brasileiro (PB) por diferentes gêneros (masculino e feminino). Os trechos do discurso emocional foram coletados na Internet e divididos em colérico, neutro, triste e SNI (simulacros de entoação neutra) para ambos os gêneros. Os parâmetros entoacionais foram analisados automaticamente pelo software ExProsodia, que se baseou em medidas de F0 (Hz) e duração (ms). Os resultados mostraram que o discurso emocional no PB pode ser caracterizado pelos graus de tensão na produção de fala. Desse ponto de vista, cada gênero e emoção relacionada pode ser localizado ao longo do eixo de tensão entoacional proposto: (i) triste>neutro>simulacro de entoação neutra>colérica, para locutores masculinos; (ii) simulacro de entoação neutra/neutra/triste>colérica, para locutores femininos. Foi possível verificar que diferença de gênero se relaciona às características fisiológicas expressas por F0 analisado automaticamente e que a tensão entoacional no discurso emocional em ambos os gêneros também pode ser uma abordagem confiável para a análise automática da expressão de emoção no PB.
Normalização de frequência de formantes e análise com dados brutos na visão de língua como um Sistema Adaptativo Complexo
Authors: Gomes Maria Lúcia de Castro
Published: October 2020

Este artigo, partindo de uma visão de língua como um Sistema Adaptativo Complexo (SAC), apresenta dados de dois experimentos inseridos em uma pesquisa que pretende descrever os ditongos [a?] e [e?] em palavras na língua inglesa e na língua portuguesa, por falantes bilíngues brasileiros e americanos. O primeiro experimento tratou do ditongo [a?] nas palavras pai/pie, pais/pies, sai/sigh, sais/sighs, com análise de medidas de duração e de F2 no início e no final do ditongo. Nas medidas do segundo formante, houve diferença significativa apenas no F2 inicial do ditongo do português entre os dois grupos de participantes. Como os valores dos formantes foram normalizados, suspeitou-se que esse processo pudesse ter encoberto diferenças importantes entre as produções dos dois grupos de falantes, e entre as palavras produzidas nas duas línguas por cada grupo. Tais suspeitas motivaram o segundo experimento, que se dedicou à análise de gráficos de plotagem de F1 e F2 dos dados brutos dos dois grupos, com a produção das palavras pai/pie. Os gráficos demonstraram que há diferenças entre as produções de L1 e L2, principalmente nos formantes no início do ditongo, sugerindo uma desestabilização do sistema na L2, com maior evidência nas produções dos brasileiros. Esse resultado, que vai ao encontro dos pressupostos de SAC, motivou uma discussão sobre normalização dos formantes em pesquisas nessa perspectiva, e a necessidade de se analisar também os dados brutos, de forma mais individualizada, em busca de diferenças mais sutis, que podem ficar escondidas nos procedimentos com dados agrupados.
