Co-educação ou classes mistas? indícios para a historiografia escolar (São Paulo – 1870-1930)
Authors: Almeida Jane
Published: September 2019

Examina a educação em São Paulo (1870/1930) mediante discussão sobre as classes mistas e a ambigüidade dos legisladores encarregados de se pronunciar sobre a co-educação dos sexos. Alguns defendiam tal prática, outros a condenavam usando argumentos morais voltados para os preceitos católicos, em oposição aos princípios protestantes que a introduziram primeiramente em suas escolas, o que demonstra que a separação Igreja e Estado na República recém-implantada nem sempre era uma realidade na vida cotidiana.

Palavras-chave: co-educação dos sexos; educação feminina.

Abstract

The article examines the education in São Paulo (1870/1930), through the discussion about the mixed classes and the ambiguity of legislators who were entrusted of manifesting on the co-education of the sexes. Some of them defended such practice; others condemned it using moral arguments headed towards Catholic precepts, in opposition to the Protestant principles that firstly introduced it in its schools, what demonstrates that the separation of Church and State in the recently implanted Republic was not always a reality in daily life.

A definição de número: uma hipótese sobre a hipótese de Piaget
Authors: Nogueira Clélia
Published: September 2019

Nenhum aspecto da matemática foi tão analisado “à luz da teoria piagetiana” quanto o número. Os resultados encontrados por Piaget e Szeminska e publicados no livro A gênese do número na criança geraram, também, inúmeras publicações acerca das suas possíveis implicações pedagógicas. Para os pesquisadores, o número é elaborado a partir da síntese operatória da seriação e da classificação, estabelecendo um tertium entre as definições de número propostas por duas das principais correntes do pensamento matemático: o logicismo e o intuicionismo. Neste artigo expõe-se o debate entre intuicionismo e logicismo sobre o número e a posição epistemológica de Piaget que levou a uma nova concepção de compreender a gênese do número na criança.

Palavras-chave: definição piagetiana de número; logicismo; intuicionismo.

Abstract

Perhaps no aspect in Mathematics has been so thoroughly analyzed than the concept of number from Piaget’s point of view. Results by Piaget and Szeminska in their book “The Child’s Conception of Number” brought forth several publications on possible pedagogical implications on the issue. For researchers, the number concept is worked out from the operational synthesis of serializing and classification, while establishing a tertium between the definitions of number, which have been proposed by two of the main mathematical thoughts, namely logics and intuitionalism. In this article the debate between intuitionalism and logics on the number and Piaget’s epistemological stance that led to a new concept on the genesis of number in the child is provided.

Keywords: Piaget’s definition of number; logics; intuitionism.

Authors: Palacios Mena Nancy , Rodríguez Márquez Miguel Armando
Published: September 2019

El objetivo de este artículo es analizar, por un lado, los resultados de las pruebas de Ciencias Sociales del examen de Estado del año 2016 en Colombia y, por el otro, las opiniones de los estudiantes sobre la preparación que reciben para dicha prueba en el marco de los procesos de evaluación de la asignatura. Se utilizó una metodología cuantitativa con información de dos fuentes: el Instituto Colombiano para la Evaluación de la Educación y una encuesta. Los datos se sistematizaron utilizando el programa estadístico Infostad Profesional. Se determinó que, si bien estas pruebas describen el logro de niveles particulares de desempeño de los estudiantes en el área de Ciencias Sociales, es necesario que estos resultados puedan ayudar a comprender aspectos curriculares y prácticas de enseñanza; esto implica un desplazamiento en la pregunta “cuánto saben los estudiantes” a “qué saben” y “qué son capaces de hacer”, y centrar la reflexión en los usos pedagógicos de los resultados de los exámenes.
Permissão Para Degradar: Uma Análise Crítica DosBiodiversity OffsetsNas Práticas Conservacionistas
Authors: Muniz Rodrigo
Published: September 2019

A conservação da biodiversidade tornou-se um compromisso inquestionável diante do seu papel inexorável para a manutenção da vida na Terra. Apesar do consensual compromisso em sustentá-la, as razões pelas quais fazê-lo ainda são alvo de discussões e controvérsias. Que valores devem reger sua proteção? Contudo, a conservação da biodiversidade está cada vez mais voltada para um lado objetivo-econômico, na qual a natureza é marginal aos interesses que parecem mais evidentes: a eficiência econômica. Esse artigo faz uma reflexão sobre os esquemas debiodiversity offsets, instrumentos cujo objetivo é a compensação pelos danos à biodiversidade provocados pelas atividades de desenvolvimento; e sobre a mudança nos valores da conservação da biodiversidade que tais instrumentos tendem a provocar. Uma mudança discursiva, institucional, técnica e material que altera o sentido de se fazer conservação e a relação humana com o mundo natural. Essa ‘nova’ perspectiva da conservação revela dilemas éticos fundamentais, e vem se tornando uma estratégia cada vez mais difundida no âmbito das políticas ambientais para a conservação.

Authors: Hoang Hai Nguyen , Anh Tran Tien
Published: September 2019

The article provides a comprehensive view of assessing technological capacity of enterprises in the context of the 4th industrial revolution, through evaluating the following criteria: capacity of technology exploitation–use–operation; capacity of technology innovation and upgrade, and capacity of new technology research and development. Limited resources have a direct impact on the capacity of technology exploitation–operation. The enterprises themselves still faces many difficulties, so the technology innovation and upgrade activities are still left open. Besides, the level of capacity of new technology research and development shows that Vietnamese enterprises have not yet achieved many achievements despite the attention, investment and support policies from the Government.

Authors: Harysandi Dea Kurnia , Marzuki Marzuki
Published: September 2019

Model yang dikeluarkan oleh International Telecommunication Union-Radiocommunication Sector (ITU-R) digunakan secara luas untuk menentukan intensitas curah hujan dalam pemodelan penjalaran gelombang elektromagnetik dalam medium hujan. Parameter yang digunakan untuk menentukan intensitas curah hujan adalah curah hujan rata-rata tahunan (Mt) dan probabilitas hujan (P0). Input data dari model ITU-R berasal dari data 40-year ECMWF re-analysis (ERA-40) dengan resolusi spasial dan temporal yang rendah. Penelitian ini menguji penggunaan data satelit Tropical Rainfall Measuring Mission (TRMM) 3A25 dan 3B43 yang memiliki resolusi spasial yang lebih baik sebagai input data ITU-R (ITU-R P.837-6). Data TRMM yang digunakan adalah data dari tahun 1998 sampai 2014. Hasil estimasi dibandingkan dengan model ITU-R standar dan kemudian divalidasi dengan data rain gauge di Kototabang dan data DBSG3 untuk Bandung. Hasil penelitian menunjukkan bahwa penggunaan data TRMM 3A25 dan 3B43 sebagai input model ITU-R P.837-6 cukup akurat untuk mengestimasi curah hujan di Indonesia. Nilai root mean square error (RMSE) dan persentase error yang didapatkan dari data TRMM dan model ITU-R tidak jauh berbeda ketika dibandingkan dengan data rain gauge dan DBSG3. Untuk keseluruhan data di Kototabang, nilai RMSE dari TRMM dan ITU-R berturut-turut adalah 21,97 dan 16,70 mm/h dengan persentase error 16,28% dan 9,63%. Untuk Bandung, nilai RMSE ketika dibandingkan dengan data DBSG3 adalah 8,72 mm/h (TRMM) dan 1,72 mm/h (ITU-R) dengan persentase error 16,18% (TRMM) dan 11,13% (ITU-R). Dengan demikian, ITU-R dengan input ERA-40 lebih akurat dari ITU-R dengan input TRMM 3A25 dan 3B43 untuk mengestimasi intensitas curah hujan menitan di Indonesia.Kata kunci: Intensitas curah hujan, TRMM, ITU-R P.837-6, Indonesia
Development of a Real-Time PCR based protocol for quantifying Radopholus similis in field samples
Authors: S J Eapen P B Krishna,
Published: September 2019

The burrowing nematode, Radopholus similis, is an obligate migratory endoparasite. Currently detection of this nematode is carried out mostly by physically extracting them from soil and then observing under a light microscope. To identify this nematode, a thorough knowledge about their morphological features is quite indispensable. Developing a DNA based detection technique makes it more convenient and accurate in detection. Though PCR based methods have been reported by earlier workers, developing a Real-Time PCR based method will enable estimating their population in field samples. In this study, Real-Time PCR primers were designed using the DNA sequences from the ITS region of R. similis. It can detect R. similis up to the limit of 100 fg μL-1 DNA. The real time PCR based detection serves as an efficient tool for the detection and estimation of this nematode from soil samples.
Effect of integrated nutrient management on growth, yield and quality attributes of black cumin (Nigella sativa L.) var. Rajendra Shyama grown under terai region of West Bengal
Authors: P Choudhury A Sen, S D Khade, J C Jana,
Published: September 2019

A field experiment was conducted during rabi seasons of 2014–15 and 2015–16 to study the effects of various combination of different levels of inorganic, organic and bio-fertilizers (Azophos) on the vegetative growth, yield contributing attributes and quality of seeds of black cumin. The results showed that the combination of 100% RDF (Recommended Dose of Fertilizer) + 15 t ha-1 FYM (Farm Yard Manure) + 4 kg ha-1 Azophos significantly improved most of the parameters related to growth of plant, seed yield and net returns. However, for production of seed oil, 75% RDF of chemical fertilizers + FYM + bio-fertilizer was recorded was the best. Most of the soil properties were improved by application of 100% RDF + FYM. Therefore from the results, it could be suggested that inclusion of organic manure and bio-fertilizer along with 100% (RDF) is the best combination for seed production of black cumin whereas for better quality seed oil 25% RDF can be substituted with FYM and biofertilizer (Azophos) in terai region of West Bengal.

Published: September 2019

Na multiplicação de genótipos selecionados, a propagação por sementes implica em maior variabilidade entre indivíduos, enquanto que o método de propagação vegetativa conserva as características genotípicas da planta matriz, tornando relevante o desenvolvimento de metodologias para propagação vegetativa. O objetivo deste trabalho foi avaliar a influência do extrato aquoso de tiririca no enraizamento de estacas de alecrim, utilizando as metodologias de irrigação das estacas com extrato diretamente no substrato e imersão da base das estacas no extrato. O delineamento de ambos os experimentos foi DIC, contendo sete tratamentos nas concentrações ANA, 0% (testemunha), 10%, 25%, 50%, 75% e 100% de extrato. Aos 35 dias foram avaliados os fatores MSR, MSP, CMR, ENR, SOBR. Concluiu-se que o experimento com irrigação de extrato de tiririca foi mais eficiente que o sistema de imersão das estacas. A concentração de 10% de extrato foi a mais efetiva no enraizamento dentre os demais tratamentos para o sistema irrigado, principalmente no desenvolvimento de massa seca de toda planta e das raízes. A auxina sintética ANA manifestou efeito superior aos demais tratamentos no sistema de contato por imersão.
Assessing the Calculation of Exchange Coupling Constants and Spin Crossover Gaps Using the Approximate Projection Model to Improve Density Functional Calculations
Authors: Sheng Xianghai , Thompson Lee , Hratchian Hrant
Published: September 2019

This work evaluates the quality of exchange coupling constant and spin crossover gap calculations using density functional theory corrected by the Approximate Projection model. Results show that improvements using the Approximate Projection model range from modest to significant. This study demonstrates that, at least for the class of systems examined here, spin-projection generally improves the quality of density functional theory calculations of $J$-coupling constants and spin crossover gaps. Furthermore, it is shown that spin-projection can be important for both geometry optimization and energy evaluations. The Approximate Projection model provides an affordable and practical approach for effectively correcting spin-contamination errors in such calculations.
BAR-Based Multi-dimensional Nonequilibrium Pulling for Indirect Construction of QM/MM Free Energy Landscape: From Semi-Empirical to Ab Initio
Authors: Sun Zhaoxi
Published: September 2019

The indirect method for the construction of Quantum mechanics (QM)/ molecular mechanics (MM) free energy landscapes provides a cheaper alternative of free energy simulations at QM level. The indirect method features a direct calculation of the free energy profile at a relatively cheap low-level Hamiltonian and a low-level to high-level correction. In the thermodynamic cycle, the direct low-level calculation along the physically meaningful reaction coordinate is corrected via the alchemical method, which is often achieved with perturbation-based techniques. Often the indirect method can lead to about an order of magnitude speedup in free energy simulation. In our previous work, a multi-dimensional nonequilibrium pulling framework is proposed for the indirect construction of QM/MM free energy landscapes. The method relies on bidirectional nonequilibrium pulling and bidirectional reweighting with the statistically optimal estimator. In the previous work, we focus on obtaining semi-empirical QM (SQM) results indirectly from direct MM simulations and MM<->SQM corrections. In this work, we apply this method to obtain results under ab initio QM Hamiltonians by combining direct SQM results and SQM<->QM corrections. The indirect nonequilibrium scheme is tested on a dihedral flipping case and a series of SQM and QM Hamiltonians are benchmarked. It is observed that PM6 achieves the best performance among the low-level Hamiltonians, while AM1 and MNDO perform less well. Therefore, we recommend using PM6 as the low-level theory in the indirect free energy simulation. The comparison between the indirect results from different SQM Hamiltonians could also provide some hints on the development of charge models. As AM1 can be corrected with the bond charge correction (BCC) to provide a cheap and accurate charge model, which is able to accurately reproduce the electrostatic potential (ESP) at HF level, PM6 would be able to do the same thing. Considering its higher similarity to the high-level Hamiltonians, the PM6-BCC model could be more accurate than the existing AM1-BCC model. Another central result in the current work is a basic protocol of choosing the strength of restraints and an appropriate time step in nonequilibrium free energy simulation at the stiff spring limit. We provide theoretical derivations to emphasize the importance of using a sufficiently large force constant and choosing an appropriate time step. It is worth noting that a general rule of thumb for choosing the time step, according to our derivation, is that a time step of 1 fs or smaller should be used, as long as the stiff spring approximation is employed, even in simulations with constraints on bonds involving hydrogen atoms.

Building Attention and Edge Convolution Neural Networks for Bioactivity and Physical-Chemical Property Prediction
Authors: Withnall Michael , Lindelöf Edvard , Engkvist Ola , Chen Hongming
Published: September 2019

We introduce Attention and Edge Memory schemes to the existing Message Passing Neural Network framework for graph convolution, and benchmark our approaches against eight different physical-chemical and bioactivity datasets from the literature. We remove the need to introduce a priori knowledge of the task and chemical descriptor calculation by using only fundamental graph-derived properties. Our results consistently perform on-par with other state-of-the-art machine learning approaches, and set a new standard on sparse multi-task virtual screening targets. We also investigate model performance as a function of dataset preprocessing, and make some suggestions regarding hyperparameter selection.
Impact of Presence and Concentration of Ionic Species on Regeneration Efficacy of Zeolites for Ammonium Removal
Authors: Canellas Judit , Soares Ana , Jefferson Bruce
Published: September 2019

One of the biggest challenges to implementing ion exchange processes in full scale at wastewater treatment works is regeneration of the media. In this paper, regeneration efficiency as a function of brine type, brine reuse, molarity and pH was investigated for the zeolite MesoLite treating synthetic solutions of ammonium. When pretreating the zeolite with KCl rather than NaCl, a 30% improvement in regeneration efficiency was found in the first cycle, which dropped to a 10% improvement in the fifth cycle. For both systems, the observed uptake capacity during the load cycle remained constant, indicating that both were effective and that the brine could be reused five times without deterioration in the performance of the zeolite. The use of KCl was more effective at lower molarities than NaCl such that equivalent regeneration efficiencies were observed at 1.0M and 0.1M for NaCl and KCl respectively. Alteration of the pH between 9 and 12 had no impact on the regeneration efficiency. However, operation at pH 12 was possible without brine. Taken together, these findings indicate that the choice of regenerant can have significant implications on regeneration efficiency and that potassium chloride might be a potentially viable alternative choice.
An Ultrafast Vibrational Study of Dynamical Heterogeneity in the Protic Ionic Liquid Ethyl-Ammonium Nitrate
Authors: Johnson Clinton , Parker Anthony W. , Donaldson Paul M. , Garrett-Roe Sean
Published: September 2019

Using ultrafast two-dimensional infrared spectroscopy (2D-IR), a vibrational probe (thiocyanate, SCN-) was used to investigate the hydrogen bonding network of a molten salt (ethyl-ammonium nitrate, EAN) compared to that of H2O. The 2D-IR experiments were performed in both parallel () and perpendicular () conditions along with temperature dependence for both EAN (14-130 ˚C) and H2O (5-89 ˚C). With polarization control, the frequency fluctuation correlation function can be separated into structural and rotational components. An Arrhenius analysis lead to independent activation energies for the isotropic, and anisotropic signals, structural spectral diffusion, and rotational induced spectral diffusion. The rotational Eas were similar for both EAN and H2O suggesting that SCN- is experiencing a similar jump model, i.e. where hydrogen bond reorientation is dominated by large angular jumps stemming from molecular rotation dynamics. The frequency pre-factors, however, were different where the more rigid and vicious EAN had a slower rate. Furthermore, the 2D-IR anisotropy and vibrational relaxation rates of EAN are frequency dependent, revealing that SCN- experiences two subensembles. We suggest that the sub-ensemble with a faster rotational timescale correlates to SCN- with more, weaker hydrogen bonds, and the sub-ensemble with a slower rotational timescale correlates to SCN- with a stronger, more directional hydrogen bond.

Kashmir Problem: Suggesting the Solutions
Authors: Kumar Dr. Ramesh
Published: September 2019

Besides being the longest unsettled dispute in the World, Kashmir is also a nuclear flash-point between two of South Asia’s opponent countries, India and Pakistan. India and Pakistan, both nuclear powers have numerous times engaged in fighting over the Kashmir province. Most Kashmiris, on the other hand have been aggressive for their right of self-determination recognized by the UN for several decades. The promise made by the first Indian Prime Minister, Nehru which is also envisaged in the Instrument of Accord of 1947 to let Kashmiris resolve their future through a Plebiscite still eludes Kashmir. In the past two periods, the region has been witness to a lot of ferocity which has also strained the relations between Bharat and Pakistan. There have been numerous rounds of talks on Kashmir between governments of India and Pakistan. Sadly, there has not been any significant positive outcome in resolving this clash. The Kashmir dispute has been studied several times in terms of its impact, economical or political, on India, Pakistan and also Kashmir. A study throughout a Kashmiri viewpoint as to what the Kashmiris desire and how the two-decade long resist has affected their resolve for self-determination make for an appealing research. The purpose of this paper is analyzing the problem of Kashmir and suggesting the solution of this problem.
SAARC: Challenges and Reforms
Authors: Kumar Dr. Ramesh
Published: September 2019

Today, the world is at a turning spot. The changes that we are undergoing are universal in scope, radical, indispensable and structural in content. As we have arrived the 21st century a sense of hopefulness prevails for achieving harmony and prosperity through effective role-play of regional as well as worldwide organizations. Many outlook Asia as having a variety of characteristics in familiar with Europe of the nineteenth century: developing international organizations, mixed domestic orders, increasing nationalism, high but differential growth rates, and bitter, emotional rivalries between insecure neighbours. The accomplishment of states in today’s world is not so much measured in terms of capacity for defending borders or generating uniquely state organizations, but in terms of ability to adapt to regional and global trends, endorse exports, draw investments, and skilled labour, deliver a advantageous environment for transnational companies, build good-looking institutions of research and higher learning, wield political influence on the regional and global scene, and also brand the state culturally in the worldwide market-place.
Haruki Murakami’s Characters and Works-as the Representation of Postmodernism.
Authors: Priya A.
Published: September 2019

As one of the most outstanding Japanese authors, Haruki Murakami always comes up with excellent ideas of surrealistic stories. The Postmodern condition is evident in most of Murakami’s novels. A sense of alienation of character and world is evident by a language medium invented to form a kind of rhythmic syntax structure which complements the illustration of the main characters’ subconscious fears and paranoia in the course of his exploration of a seemingly chaotic world. His portrayal of characters is unique and significant that expresses the dichotomy of characters who fight between reality and fantasy. Nevertheless, their ambition to be free from the structures that bound them do not always come true. Some of them left their symbolic mechanism to enter another one. In the end, the characters cannot be the Other; as long as they are still in the clutches of a particular token device they would only be able to be the other. His Characters explore themselves in search of meaning of their existence. His characters often utter speeches which directly contradict their subsequent actions.They are male, middle-aged, leading aimless existences. They enjoy preparing and eating such western foods as spaghetti; they love American pop culture, particularly music of the 1960s and 1970s; and they are hedonistic and idle. They either engage in casual love affairs or fantasize about having them. His novels like After dark(2004) and The Wind-Up Bird Chronicle (1994) is postmodern works by the coexistence of the surreal scenes.
Agonising Liminality: A Study Of Orhan Pamuk’s Snow
Authors: Ezhugnayiru A.
Published: September 2019

This article throws light on the distress a liminal experience could give for an individual or to a community who belong to a specific ethnicity, regarding the novel Snow written by the Turkish writer, Orhan Pamuk. Turkey located geographically in the edges of landscapes where the east and the west meet encounters this liminality over a couple of decades and stays as the setting of the novel Snow. In the liminal state, people fall in the breaks and crevices of the social structure which they think.The liminal stage individual encounters, a period of instability and vulnerability. Orhan Pamuk's Snow reflects the unpleasant experience of progress from the Islam arranged Ottoman Empire to the Republic of Turkey. The setting of the novel, the town of Kars, a periphery city fringe to Turkey stands as a representative of Turkey's minimization from the world. Pamuk supplements the fruitless condition of the city all through this novel.
An Analysis of the fastest growing Indian economy facing the situation of unemployment-A Dichotomy
Authors: Agarwal Dr. DR , Sushma Ms.
Published: September 2019

Classical economist believed that full employment was a normal situation in the economy- in other words all those persons, who are qualified to work, willing to work and able to work at the current wage rate, get the job without any considerable delay. Supply could create its own demand, hence there was no need for any kind of Govt. Intervention in the economic affairs of any economy (Production Arises Due to Joint Actions of all the factors of Production but labour is the most important) If disequilibrium exists between the forces of demand and supply conditions of labour, commodity and savings, it could be automatically adjusted with the flexibility of wage rate, price and interest rate. The real wage rate is determined at a point where the demand of labour is equal to supply of labour. According to Pigou, decline in Money wages increases the volume of employment through reduction in cost and prices of Goods, (Since prices do not respond in the same proportion, therefore real wage also declines with the fall in nominal wage rate) During the great depression of thirties, workers were willing to accept a nominal wage cut but volume of employment was constantly declining Keynes came on this juncture and gave his macro-economic analysis wages are not only a part of the cost of production but also the income of the workers. This reduces the level of aggregate demand and hence volume of employment. Psychologically nobody wants money wage to be cut (neither it is theoretically sound, nor practically possible). In almost all countries laws have been formulated for minimum wages, unemployment insurance, sickness, maternity benefits and a number of other social security measures (Transfer payments). UN report (2010 to 2019) shows that working population  (population between the age 15-64) is 67% percent and on the other side, India has become a fastest growing economy in the world, but jobs are not increasing Fundamentally when an economy grows it means output and employment both the variables respond in the positive direction  An attempt has been made to examine this mismatch /dichotomy  in this research paper.

Analysis Of Concrete Tunnel Frameworks Subject To Fault Removal
Authors: Teja Geddam , Babu A.P.Nagendra
Published: September 2019

An earthquake fault rupture generates two types of ground motion: permanent quasi-static dislocations and dynamic oscillations, characterized by strong pulses. This study investigates tunnel’s response to two different conditions using a 2D finite element program; the first one has a static dislocation corresponding to different earthquake magnitudes, while the second combines near-field seismic motions with three specific peak ground accelerations along with permanent dislocations. The impulsive ground motions affect the lining response further to other influential factors such as fault type and dip angle, making changes in sectional forces, displacement, and shear distortion of the lining. Moreover, pulse intensity, period, and frequency content are effective characteristics of impulsive motions that change in final response of the lining, subjected to subsequent static dislocations. Based on the second condition, at low PGAs, the pulse type is more effective to final response of the lining, due to forward and backward momentum specifications in impulsive motions. For earthquakes with high PGA and larger values in nearfield parameters, both the pulse type and period are effective. The tunnel displacement increases at PGAs as large as 0.7 and 1g, unlike the low PGA as large as 0.35g, because of increasing soil stress and plastic strain, respectively.

Using Technology Acceptance Model to Study Customers’ Perception Towards Green Banking
Authors: Shrivastava Deepak , Shrivastava Apurva , Prakash Gyan
Published: September 2019

Tech-friendliness in this new era is an important quotient considered and the persons’ acceptance towards the technology frequency matters a lot. But still the frequency varies from person to person, this brought in the concept of Technology Acceptance Model given by Fred Davis in 1989. The theory of TAM is based on two theories that are Theory of Reasoned Action and Theory of Planned Behavior, TAM is extended version of these two. Green Banking is a new technology introduced by the banks that focuses on the growth of Sustainable development and Banking system too. Thus, banks ask their customers to use it or practice it in their daily life transactions. But every customer has their own point of view on the usage of Green banking. Thus, the research aims to understand the customers’ perception towards the Green Banking for this TAM is used. The research states that Perceived risk is the primary factor that is followed by perceived usefulness and perceived ease of use that impacts the decision to use green banking. Thus, the behavioral intention results in actual use of green banking usage for which people are trying to accept the new technology. So, the banks have earned points for creating awareness among their customers but still they have to work hard and clarify their customers’ problems and vanish that hitch that is stopping them to use green banking easily.
