Integrating Parabolic Trough Solar Fields Into Computerized Maintenance Management Systems
Authors: Price Hank , Sommers Rick , Imponenti Luca , Boyle Keith , Díaz Callejero Manuel
Published: March 2024

Computerized maintenance management systems for power plants are not well suited for application in solar fields. They work well for tracking maintenance requirements on the hundreds or even thousands of pieces of equipment in conventional power plants, but they do not work as well tracking the maintenance requirements on hundreds of thousands of identical pieces of equipment found in a solar field. A database application, known as a field status program, is being developed for tracking the maintenance and status of collectors and components in parabolic trough solar fields as a complement to the computerized maintenance management system. This system, patterned after a similar system developed by the KJC Operating Company in the 1990s, provides a valuable tool for the O&M of parabolic trough solar fields. This paper describes the development and application of the tool and the new expanded capabilities that are being added to further enhance the O&M of solar fields.
Data-Free and Data-Driven Uncertainty Quantification in Turbulent Flow Simulations
Authors: Iaccarino Gianluca
Published: March 2024

Fluid simulations and predictions of turbulent motions play a critical role in many fluid flow scenarios but particularly when the flow is prone to separation. Despite continued advances in high-fidelity turbulent flow simulations, closure models based on the Reynolds-Averaged Navier-Stokes (RANS) equations are projected to remain in use for considerable time to come, especially when rapid responses are required or large number of conditions need to be studied. However, it is common knowledge that RANS predictions are corrupted by epistemic model-form uncertainty to a degree which is unknown a-priori. Hence, to obtain a computational framework of predictive utility, a model-form Uncertainty Quantification (UQ) framework is indispensable. UQ enables the characterization of the potential errors in the simulations and leads to prudent estimates of the impact of turbulence assumptions on the quantity of interest. Over the last several years we have developed an approach that uses a spectral decomposition of the modeled Reynolds-Stress Tensor (RST) which is the building block of all RANS closure. This strategy allows for the introduction of decoupled perturbations into the baseline intensity (kinetic energy), shape (eigenvalues), and orientation (eigenvectors) of the Reynolds stresses. Within this perturbation framework, we look for a-priori known limiting physical bounds. Since these bounds are universal, they can be used to constrain uncertainty estimates in any predictive flow scenario. Thus, even in the absence of relevant training data, we can maximize the spectral perturbations in order to obtain conservative uncertainty intervals. The approach has been proven to be useful in a variety of applications. On the other hand, any reference data (experiments or high-fidelity resolved turbulence simulations) can be used to further constrain the uncertainty estimates using commonly available data assimilation techniques. This provides a data-driven path towards UQ estimates. We will demonstrate our framework on canonical flow problems using two common data-driven approaches, random forest regression and deep neural networks. We consider a database of high-fidelity simulation data for the flow over a separated flows and compare the resulting uncertainty estimates to conventional RANS closures and available experimental data.

Data-driven Reduced Order Models for Multi-scale, Multi-physics Systems
Authors: Duraisamy Karthik
Published: March 2024

This talk presents advances towards the development of effective reduced order models (ROMs) for complex multi-scale multi-physics problems. As a representative application, we consider combustion dynamics in a rocket engine, which is characterized by the coupling between heat release, hydrodynamics and acoustics. The first part of the talk is focused on improving robustness and consistency: A structure-preserving transformation of the state variables is used along with a discretely consistent least squares formulation to yield symmetrized model operators in both explicit and implicit time integration settings. The resulting reduced order model is well-conditioned and globally stable. Local stability is promoted via limiters that enforce physical realizability. The second part of the talk is focused on improving accuracy: Dimension reduction approaches based on static linear manifolds are not effective in addressing multi-scale problems with significant convection. To help mitigate this issue, we present formulations using adaptive spaces. Opportunities for further improvement are also highlighted. The last part of the talk discusses tractability : ROMs are used to enable computations of problems for which full order models are not affordable. In particular, we develop a multi-fidelity framework in which component-level ROMs are trained on small domains, and integrated to enable full-system predictions in an affordable manner. In essence, geometry-specific training is replaced by the response generated by perturbing the characteristics at the boundary of the truncated domain. This training method is shown to enhance predictive capabilities and robustness of the resulting ROMs, including conditions outside the training range.

Avaliação da eficiência do processo avançado de oxidação para remediação de solo contaminado por BTEX
Authors: Panício Paloma Pucholobek , Ramsdorf Wanessa Algarte , Vidal Carla Bastos
Published: March 2024

A contaminação dos solos por hidrocarbonetos derivados de petróleo, proveniente de vazamentos, suscita grande preocupação devido à complexidade e especificidade desse compartimento ambiental, bem como ao potencial poluidor intrínseco a esses compostos, especialmente os BTEX (benzeno, tolueno, etilbenzeno e xilenos), que compõem a fração solúvel dos combustíveis fósseis. Medidas de remediação físicas, químicas e/ou biológicas são, portanto, aplicadas para conter ou eliminar a pluma de contaminação formada após a percolação dos contaminantes pelo subsolo. Com base no exposto, o presente trabalho teve como objetivo avaliar a eficiência do processo avançado de oxidação (AOP) promovido pelo agente oxidante persulfato de sódio frente a uma contaminação por BTEX.O solo virgem amostrado, com textura franco-arenosa, foi submetido a um processo de contaminação em laboratório e, posteriormente, a um processo de remediação em ensaios oxidativos em batelada. Foram utilizados como agentes de oxidação o persulfato de sódio isolado e em sistema combinado com peróxido de hidrogênio. Esses agentes foram avaliados com base em três critérios principais: (1) redução dos níveis de BTEX em fase sólida e líquida; (2) efeitos ecotoxicológicos com sementes de Lactuca sativa; e (3) avaliação dos teores dos oxidantes consumidos no processo.Os resultados revelaram que o sistema isolado PER 20/1 (20 mols de persulfato para 1 mol de BTEX) foi a condição oxidativa mais efetiva para a remediação do solo avaliado, com uma eficiência de 99,4% na remoção dos BTEX. Isso foi observado em todos os parâmetros de qualidade considerados nesta pesquisa, indicando o potencial promissor dessa técnica para a remediação de solos contaminados com BTEX.

Published: March 2024

Este estudo avaliou a ocorrência de 24 fármacos e desreguladores endócrinos em 13 mananciais de abastecimento de água do Brasil. Realizaram-se amostragens mensais da água bruta de mananciais lóticos e lênticos, por um período de até 13 meses, abrangendo os períodos de seca e chuva. Os contaminantes foram extraídos e concentrados por extração em fase sólida (SPE) e analisados por cromatografia de fase gasosa ou líquida acoplada à espectrometria de massas (GC-MS ou LC-MS/MS). O desregulador endócrino bisfenol-A (BPA) foi frequentemente detectado nas amostras de água (79%), seguido pelo antialérgico loratadina (LRT), em concentrações medianas de, respectivamente, 27,7 e 15,6 ng/L. A cafeína (CAF), estimulante, não foi detectada em nenhuma das amostras, indicando não ser um bom marcador de poluição antrópica. A Análise de Componentes Principais (PCA) permitiu correlacionar os compostos e suas concentrações com o tipo de manancial e o período de coleta. Foram observados dois clusters: um constituído por amostras de ambiente lótico, coletadas no período seco, que exibiram altas concentrações de estrona (E1) e estradiol (E2); e o outro, mais heterogêneo, associado a amostras coletadas principalmente em ambiente lêntico durante o período chuvoso. Embora algumas correlações tenham sido identificadas, a maior parte dos dados apresentou uma disposição homogênea, não permitindo a observação de um padrão claro entre a prevalência de contaminantes e o tipo de manancial ou período amostrado.
Remediation of Contaminated Soil by Polycyclic Aromatic Hydrocarbons Using Composting
Authors: Lim Apollonia Huei Jhe , Jusoh Muhammad Noor Hazwan
Published: March 2024

Polycyclic aromatic hydrocarbons (PAHs) were one of the most concerning organic and toxic pollutants in the world. Since the 20th century, there had been no improvement in resolving or reducing the discharged or released amount of PAHs into the soil or environment. Detecting PAHs (PAHs) involved collecting environmental or biological samples, extracting PAHs using specialized techniques, and analyzing them with advanced methods like gas chromatography-mass spectrometer (GC-MS) or high performance liquid chromatography (HPLC). This process was crucial for assessing contamination levels, understanding health risks, and guiding environmental safety measures. There was no full replacement with existing technology and materials that would not release the PAHs. Now, the PAHs pollutant has caused many cases related to the impact of PAHs on the environment and human health, prompting immediate action for resolution. The remediation to remove the PAHs from the contaminated soil was conducted using the composting method. The few kinds of composting methods were vermicomposting, which used earthworms to decompose PAHs in the contaminated soil, in-vessel composting that ran the aerobic process under a close air space tank, and aerated pile that implemented the aerobic process in an open air space. The bulking agent of in-vessel composting and aerated composting was the same. Actually, these three composting methods were under bioremediation to remove PAHs from contaminated soil. There were a few challenges that would be faced by the government, the people, and the research in the future. Some recommendations have been provided to face these future challenges.
Review on Organochlorine Pollution in Malaysia
Authors: Ngu Wei Jie , Hua Ang Kean , Zakaria Zulayti , Jusoh Muhammad Noor Hazwan
Published: March 2024

Organochlorine is a type of persistent organic pollutants which can last long in environment due to the resistance towards the microbial degradation. Previously, the organochlorine pesticides are widely used to reduce the pests in the farm so, the crop yield could be increased, and the losses can be decreased. The organochlorine pesticides previously are used without having a proper study on the effect of organochlorine to the environment. Although the use of organochlorine pesticides has been banned, the residues of organochlorine from previous usage, still exist in the environment, causing negative impacts to the environment and human health. The distribution of the organochlorine pollution in Malaysia is required to be studied more to ensure that the organochlorine concentration will not be increasing according to time. Due to the ban of organochlorine pesticides, other pests control methods such as organophosphate pesticides, and integrated pest management are being used by the farmers. However, there are challenges raised such as financial problem of the farmers to afford the new chemicals or methods and the negative effect from the use of new chemicals, and these challenges should be solved to improve the pest control in Malaysia. Impacts of organochlorines on human health and environment are discussed in this review to show the hazard of organochlorines.

Authors: Kho Brendan Lik Sen , Hua Ang Kean , Ahmad Mohd Fadzil Ali
Published: March 2024

The growing population has led to the increase in contamination to the soil, affecting the soil environment which indirectly affects importance of human health. Soil remediation is important to remove and reduce the level of contamination in the soil medium. If the contaminants present in the soil is not remediated, the possibilities of it to spread will increase due to the presence of water flow inside the soil medium, further contaminating soils that are previously clean. Hence, several nanotechnologies and nanomaterials were discovered by researchers, allowing the remediation of soil that are contaminated by different pollutants to be effectively carried out. The nanotechnologies and nanomaterials discussed in this paper involves physical, chemical and biological type of remediation. It is being known that nanoscale remediation can have higher effectiveness compared to microscale remediation. Most of the discussed nanotechnologies requires longer period of time but the effectiveness in the removal or reduction of contaminants are very high. Remediation of contaminated soils allow more land to be available for human development and exploitation. Humans are urged to reduce the chances of contamination activities or accident as contamination to the soil can adversely affect the local environment and the human health.

The purpose of this study is to find out what creativity is, the importance of the aspect of creativity in early childhood, the important role of the teacher as a facilitator in encouraging creativity and the linkage of creativity based on the perspective of progressivism. As is known, a common occurrence to date is the existence of a number of problems which show that there are still many individuals who are unable to present their work in real or real terms; the majority of these individuals prefer to duplicate the work of others. The inability to develop a work is an indication of a lack of imagination. Creativity is not a foreign concept for children studying in kindergarten or PAUD, because everything they do in kindergarten and early childhood is basically creative. Therefore, teachers and parents should realize the importance of creativity for the survival of their children starting with their earliest education. Education is an effort to grow and develop the characteristics of intelligence, skills, and character of students, which is carried out in stages. All forms of education, including early childhood education, must be implemented based on the philosophy of education. The flow of progressivism is one of the educational understandings of the existence of a flow in education that supports change or progress in the application of education. The writers do library research of this type (library research). The creativity of early childhood, as viewed through the lens of progressivism, is bolstered by associated theories, which are designed to provide readers with information that may be implemented in the everyday education of children.

Authors: Rahman Md. Moshiur , Jui Jannatun Nahar , Rahman Md Rashedur
Published: March 2024

Dry direct seeding is a new technology to address the water scarcity problem faced in rice culture in boro season. An experiment was run at Bangladesh Agricultural University in Mymensingh, to determine the impact of the sowing date and irrigation schedule on the yield potential and cost effectiveness of boro rice grown under a dry direct seeding system. The experiment was laid out in a split-plot design and consisted of two sowing dates viz. 10 February and 02 March; and five irrigation regimes viz., no irrigation, one irrigation at 25% field capacity (FC), two irrigations (at 25% FC and at 1 week after 25% FC), three irrigations (at 25% FC, at 1 and at 2 weeks after 25% FC) and four irrigations (at 25% FC, 1, 2 and 3 weeks after 25% FC) replicated thrice assigning sowing date in main plots and irrigation in sub-plots. The result showed that BRRI dhan58 sown on 10 February with four irrigations (at 25% FC, 1, 2 and 3 weeks after 25% FC) produced the highest grain yield and economic return which was statistically comparable to those for two (at 25% FC and at 1 week after 25% FC), and three irrigations (at 25% FC, at 1 and at 2 weeks after 25% FC). The present study concludes that rice variety BRRI dhan58 can be cultivated successfully to achieve maximum yield and economic return by sowing the seed during 10 February to 02 March and applying 2 - 3 irrigations at the vegetative phase in dry direct seeding system.

A presente pesquisa buscou como objetivo analisar o papel da formação docente para a inclusão escolar de alunos com necessidades educativas especiais. A pesquisa consistiu em uma revisão sistemática da literatura, seguindo as diretrizes do PRISMA, com uso de palavras-chave específicas e operadores booleanos. Foram aplicados critérios de inclusão rigorosos para selecionar estudos publicados entre 2020 e 2023, resultando na análise de 5 artigos científicos. Como resultado, constatou-se que a formação adequada dos professores é fundamental para uma educação inclusiva e equitativa, sendo as lacunas identificadas na formação inicial obstáculos significativos para a prática inclusiva nas escolas. A falta de formação adequada pode gerar barreiras que comprometem a inclusão efetiva, tornando os ambientes escolares excludentes. Assim, a responsabilidade compartilhada de toda a instituição no processo de formação docente é destacada, ressaltando a importância de políticas institucionais que promovam a formação continuada dos educadores. Além disso, é enfatizada a essencialidade da educação inclusiva para a igualdade de direitos e participação social dos alunos com necessidades especiais, requerendo oportunidades formativas e apoio aos professores. A reflexão crítica sobre a prática docente, junto à valorização da diversidade humana, são aspectos cruciais a serem incorporados na formação dos professores, que não deve se limitar a aspectos instrumentais, mas promover uma visão ampla sobre o papel do professor na construção de uma educação verdadeiramente inclusiva. Portanto, os resultados reforçam a necessidade de investimentos na formação docente para enfrentar os desafios da inclusão e promover uma mudança profunda nas práticas educativas, visando ambientes educacionais que reconheçam e valorizem a diversidade, garantindo uma educação de qualidade para todos os alunos.

O objetivo deste estudo foi verificar o conhecimento de gestantes sobre os benefícios da amamentação para a saúde do bebê a curto e longo prazo, mas também comparar o grau de conhecimento com variáveis ​​sociodemográficas e clínicas. Esta pesquisa trata-se de um estudo transversal, descritivo, por meio de questionários aplicados a gestantes. A análise estatística foi realizada no programa SPSS 26.0, com nível de significância de 5%. Foi aplicado um questionário sobre os benefícios da amamentação para gestantes para mensurar seu conhecimento sobre o tema. Participaram da pesquisa 78 gestantes. Ressalta-se que grande percentual de gestantes desconhecia muitos benefícios da amamentação, como “maior escolaridade” (85,9%) e “maior renda” (89,5%). Dos 17 benefícios da amamentação listados, apenas cinco eram conhecidos por mais de 50% das gestantes: redução do risco de “morte por doenças infecciosas”, “diarréia”, “infecções respiratórias”, “má oclusão dentária” e “alergias”. não houve diferença no grau de conhecimento sobre os benefícios do aleitamento materno entre as gestantes que realizaram o pré-natal no serviço de pré-natal de “baixo risco” ou “alto risco”. Observou-se baixo nível geral de conhecimento sobre a maior parte do conteúdo questionado. Enfatizamos a necessidade de melhorar o conhecimento das gestantes sobre os benefícios da amamentação, focando no impacto na saúde do seu futuro filho até a idade adulta. Essa abordagem deve ocorrer nas consultas pré-natais de rotina, nas consultas pré-natais pediátricas e nas campanhas informativas.

Published: March 2024

In recent years, the policy of promoting rural revitalization has been deepening, and the rural economy has achieved certain development. However, cultural support is indispensable for the realization of high-quality rural development. The source of art is often buried in the land, and the vitality of the land cannot be separated from the nourishment of art. In this paper, we take the case of Da Yuan Community in Yong Zhou City, Hunan Province, as an example, and adopt the case study method to explain how to use the combination of art and natural environment to promote psychological health and emotional development of individuals as well as social harmony based on the ecological aesthetics education and art healing. Eco-beauty education and art healing can not only make the rural culture grow with vitality and richness but more importantly, art is deeply integrated with the countryside, which positively impacts the overall growth of left-behind children.
A Point Cloud Contour Extraction Method based on Plane Segmentation
Authors: Lu Lei , Gao Ran , Pan Wei , Tang Wenming
Published: March 2024

A method based on plane segmentation and dimensionality reduction for extracting incomplete and slow contour features of object point clouds is proposed. The method consists of two main steps: plane segmentation and contour extraction. In plane segmentation, the random sample consensus (Random Sample Consensus, RANSAC) algorithm is optimized based on principal component analysis (Principal Component Analysis, PCA); the optimized planar point cloud is then subjected to dimensionality reduction, and the contour features are extracted using gradients. Experimental results show that the method can effectively segment point clouds and extract the contours of target surfaces, and has great potential for application in industrial inspection and other fields.

The dark channel priori dehaze algorithm based on minimum filtering is known to consume a significant amount of computational and storage resources for transmittance optimization, resulting in issues such as halo phenomena in gray and white areas of the image. In contrast to this, the proposed algorithm in this paper offers a novel approach to dark channel image dehazing. By leveraging dark channel a priori knowledge, the algorithm introduces an adaptive adjustment factor to enhance the realism of restored image details. Furthermore, the algorithm employs guided filtering for transmittance map refinement instead of traditional image keying. Subsequently, the haze-free image is reconstructed using the estimated atmospheric light and refined transmittance maps based on the atmospheric scattering model. Post image restoration, brightness and contrast are enhanced, and image optimization is achieved through adaptive contrast histogram equalization to improve visual quality. The experimental findings reveal that the proposed algorithm not only accelerates the efficiency of image dehazing but also sustains color fidelity in gray and white regions, yielding aesthetically pleasing outcomes.
LIFE CHANCES AND STRUCTURAL INEQUALITY
Authors: MÜLLER HANS-PETER
Published: March 2024

The article delves into the historical trajectory of global inequality, tracing the transition from an era of relative equality to the emergence of profound disparities following the Industrial Revolution and the rise of the West. It scrutinizes the Eurocentric narrative of progress, emphasizing the pivotal role of scientific advancements, technological innovations, and capitalist expansion in shaping the Western ascendancy. Furthermore, it explores the concept of life chances as a lens through which to analyse structural inequality and the distribution of resources among individuals. The discourse extends to the revaluation of values in the context of sustainability, advocating for a shift towards a more sustainable and equitable societal framework. The paper underscores the enduring challenges posed by durable inequality and the allure of the Western lifestyle to less privileged regions. Through a multidisciplinary lens encompassing historical, sociological, and ecological perspectives, it offers insights into the complexities of global development, social stratification, and the quest for a more just and sustainable world order.

Anemia is the condition in which hemoglobin level may become lower than normal <11.0g/dl. According to an estimate, about one-third of the world's population (over 2 billion) are anemic. The study aimed to determine the Prevalence of anemia and associated factors among pregnant women at Kausar Hospital Mother and Child Health Care Centre Khairpur Mir’s, Sindh, Pakistan. The cross-sectional study was conducted from August to December 2019. A total number of 100 pregnant women were randomly included in this study. A predesigned questionnaire was filled out by face-to-face interviews consisting of socio-demographic characteristics, including Name, Age, gestational age, educational level, occupation, and monthly income. Anemia was classified as per World Health Organisation (WHO) criteria. The prevalence rate of Anemia in the present study was 69%. Minimum Haemoglobin levels were observed at 5.6 g/dL, and maximum Haemoglobin levels were observed at 12.4 g/dL with an average Haemoglobin of 10.05 g/dL ±1.44. Among them, 49% had mild anemia, 17% moderate anemia, and 3% severe anemia. At the same time, the patients were divided into age groups of 15-20 years, 21 to 25 years, 26 to 30 years, and 31-35 years to compare Anemia or Haemoglobin levels. Results showed a higher prevalence of anemia between the ages of 26 and 30. The minimum age was observed to be 20 years and a maximum of 35 years, with an average age of 28.12 years ±2.5 years.  It was observed that the prevalence of Anemia was higher in 7-9 gestational months; socio-economic factors (Age, Gestational month, Number of children, and income source) showed significant association with Anemia. The present study concludes that the Prevalence of Anemia and Associated Factors among Pregnant Women at Kausar Hospital was 69%. Among them, 49% had mild anemia, 17% moderate anemia, and 3% severe anemia.

Published: March 2024

The article presents a method of production of foam concrete, which involves two-stage injection of foam. The proposed method involves improving the pore structure of foam concrete, due to a more uniform distribution of pores throughout the volume of the material. Laboratory tests were carried out for two types of samples, represented by the proposed method of foam concrete production by two-stage foam injection with the use of modified additive in comparison with the classical foam concrete. The density of Type 1 samples varies from 410 to 793 kg/m3 (coefficient of variation from 5.12 to 7.31%), while the density of fiberboard samples lies within the range from 539 to 655 kg/m3 (coefficient of variation from 2.66 to 3.14%).  The results of greater variation of densities by height in the Type 1 sample relative to the Type 2 sample indicate the influence of the technological process of foam concrete production on the quality of the pore structure of the material. The results of strength evaluation showed a large scatter of Type 1 samples in relation to Type 2 samples. The highest values of CM strengths are logically observed in the lower part of the sample and the lowest in the upper location: 44.04 and 32.33 kg/cm2 (coefficient of variation from 5.15 to 9.54%). For Type 2 samples, the same values are 55.18 and 44.44 kg/cm2, for the lower and upper locations, respectively (coefficient of variation from 2.79 to 5.35%). The results of thermal conductivity measurements of Type 1 samples range from 0.098 to 0.203 W/m0C (coefficient of variation from 4.59 to 11.88%), while the densities of Type 2 samples lie between 128 and 162 W/m0C (coefficient of variation from 3.38 to 3.55%).

Poverty is a problem in the development process in most countries, especially in developing countries such as Indonesia. Analyzing the factors that influence poverty is important in formulating effective and targeted policies. This study aims to analyze the independent variables of village funds, unemployment rate, human development index (HDI), and gross regional domestic product (GRDP) affecting the dependent variable of the number of poor people in Indonesia in 2022. The study used the Ordinary Least Square (OLS) model to analyze cross-section data from 34 provinces in Indonesia in 2022.  The results show that village funds and GRDP have a significant positive influence on the number of poor people, but HDI and unemployment rate do not have a significant influence. The findings make a significant contribution to understanding the factors that contribute to the poverty rate in Indonesia, as well as providing a basis for formulating more effective development policies to reduce the poverty rate in the future.

Swarna rice cultivars (Indian cultivar) are widely grown in the northern part of Bangladesh because of their higher yield, drought tolerance, higher quality of grain and good plant appearance. Therefore, a study was conducted to observe genetic diversity among eight Swarna cultivars grown in Bangladesh. The genetic diversity of the cultivars was assessed by one hundred SSR (simple sequence repeat) markers. Among these, forty-four primers were polymorphic. In total, 188 alleles from eight rice genotypes with an average of 4.27 alleles per locus were identified. Allele numbers varied from 2 to 11. The average polymorphism information content (PIC) was 0.533, with a range of 0.195 to 0.889. The most suitable markers found were RM149, RM232, and RM3421, which provided the highest PIC value of 0.889. Genetic dissimilarity coefficient values between pairs indicated that the Guti Swarna and Nepali Swarna cultivars along with the Guti Swarna and Deshi Guti Swarna cultivars were the most genetically distant (0.818) cultivars whereas the Nepali Swarna and Nironjon Swarna cultivars were the closest (0.091). A dendrogram constructed based on polymorphism indicated five major groups. It was observed that the Guti Swarna and Sumon Swarna cultivars formed two different solitary groups, I and II whereas the Nepali Swarna and Nironjon Swarna formed group III, the Lal Swarna and Swarna5 constructed group IV, and the Deshi Guti Swarna and Tiger Indian Swarna were in group V. Our findings may help in designing appropriate cross combinations for further improvement of Swarna cultivars.
