Effects of customer satisfaction on Customer Loyalty through Service Quality and Features in a Selected Bank
Corresponding Author : Choudhury Abul Anam Rashed (rashed-ipe@sust.edu)
Abstract :
The loyalty of customers is needed for long-term business. Service quality and service features are certain criteria for customer satisfaction. The research investigates the relationship between customer loyalty with service quality, features, and customer satisfaction. A survey-based analysis based on a semi-structured questionnaire was conducted. SPSS-22 and Microsoft Excel 2016 have analyzed primary data. A conceptual model was developed to testify to the linkage between customer loyalty and satisfaction with service features and quality. The formulated hypotheses were tested. The…
Determination of Genetic Diversity among Local Mandarin Oranges (Citrus reticulata) Using Mature Seed Derived Calli through RAPD Markers
Corresponding Author : Hammadul Hoque (hammadul-geb@sust.edu)
Abstract : Orange (Citrus reticulata) is cultivated at several districts of Bangladesh but the genetic diversity among cultivars is still unknown. This research aimed to find out the diversity among locally grown nine mandarin orange (C. reticulata) cultivars. For this purpose, calli were initiated and used as a source for genomic DNA. Murashige and Skoog (MS) medium supplemented with phytohormones (2,4-dichlorophenoxyacetic acid, benzyl adenine, 1-naphthalene acetic acid, kinetin, indole-3-butyric acid) and malt extract were used for calli induction. DNA extracted from the…
Finite element algorithm for solving one-dimensional Richards’ equation
Corresponding Author : M. Sayful Islam (sayful-mat@sust.edu)
Abstract :
Accurate, efficient, robust, and stable numerical solution of Richards’ equation for variably saturated-unsaturated water flow through porous media is an extremely challenging task for any numerical integrator due to its highly nonlinear behavior. In this study, we have solved a one-dimensional Richards’ equation that frequently describes saturated-unsaturated water flow in homogeneous soil layers. The obtained solution is a set of an ordinary differential equation derived from mass conservation principles. We have used the finite element method for domain discretization of…
Hydrothermal synthesis of a Novel Transition Metal Oxyfluoride compound containing 2-Methylimidazole: Crystal Structure, and Characterization
Corresponding Author : Belal Ahmed (belal-che@sust.edu)
Abstract :
Novel Molybdenum oxyfluoride compound [Zn(C4H6N2)4][MoO2F4] consisting of tetrahedral [Zn(C4H6N2)4]2+ cation, and octahedral [MoO2F4]2- anion have been successfully synthesized by a hydrothermal method in acidic conditions. Single crystal X-ray diffraction analysis confirms that the synthesized compound crystallized in the monoclinic space group, P2/c, and reveals a pseudo–one-dimensional structure through the strong inter-ionic hydrogen bonding interactions. The oxide and fluoride atoms form the inter-ionic hydrogen bonding network with the neighboring nitrogen or carbon atoms of the 2-methylimidazole ligand. The hydrogen bond network…
Construction worker’s safety measures: A comparative risk analysis of construction sites of City Corporation and municipal areas of Bangladesh
Corresponding Author : Towfiqul Islam Khan (khan-gee@sust.edu)
Abstract :
This study assesses the risk status of construction workers at different levels of municipal and local government. Construction workers perform a crucial function for the structural and financial improvement of the country. This area is much less mechanized, but it requires more effort. Security issues are the main topic of this business. Various information has shown that this discipline is incredibly dangerous. This research attempted to evaluate the threat reputation of manufacturing workers at different levels municipal and municipal level…
Analyzing Groundwater Potential Recharge Zones Using AHP, RS and GIS Techniques in Bishwamvarpur Upazila, Bangladesh
Corresponding Author : Towfiqul Islam Khan (khan-gee@sust.edu)
Abstract : This study shows the demarcation of capacity zones where groundwater can get recharged in Bishwambharpur Upazila in Sunamganj, Bangladesh by using analytic hierarchy process, remote sensing, and geographic information system techniques. To create thematic maps of several geospatial factors having an immediate or indirect effect on the availability of groundwater, geology, slope, geomorphology, soil, LULC (land-use land-cover), drainage density, lineaments density, and rainfall distribution, remotely sensed and conventional statistics have been obtained from several reasserts and analyzed in GIS software.…
Development of an efficient protocol for Robiquetia spathulata (Bl) J.J. Sm. an Endangered Orchid Species Through in vitro Techniques
Corresponding Author : Tapash Kumar Bhowmik (tapashptc@gmail.com)
Abstract : Robiquetia spathulata (Bl) J.J. Sm. is an epiphytic endangered orchid species of Bangladesh and PM (Phytamax - Arditti, 1977) basal medium was best for seeds germination than KC (Knudson, 1946), MS (Murashige and Skoog, 1962), MVW (Modified Vacin and Went, 1949) media. Sucrose was highly favorable for germination as a source of carbohydrates than glucose and lactose. The highest mean increased length of seed originated seedlings (3.68 ± 0.22cm) and individual shoot bud (3.37 ± 0.18cm) were achieved on 0.8%…
Evaluation of phenotypic and genotypic variation of local pumpkin germplasm for improved breeding purposes
Corresponding Author : Romel Ahmed (romel-fes@sust.edu)
Abstract : Pumpkin (Cucurbita moschata), a popular vegetable in Bangladesh, has a wonderful source of minerals, fibers, vitamins, antioxidants, and nutrients. Attempts were taken in the present work to select the best parents of pumpkin (Cucurbita moschata) among the 20 local germplasms for improvement breeding. The collected germplasms were evaluated for phenotypic and genotypic variations based on flowering days, vine length, fruits length and weight, yield and pericarp length that were found to differ significantly (p< 0.01). Time required to flowering varied…
Natural Regeneration and Diversity of the Tree Species at Satchari National Park in Bangladesh
Corresponding Author : Rabeya Sultana (rabeya02-fes@sust.edu)
Abstract : Natural regeneration is the basic stage of forest dynamics which helps in the recovery of ecosystem functions. Therefore, the future of a forest ecosystem depends on proper knowledge of the regeneration status and composition of tree species. Based on regeneration data collected from a total of 50 sample plots, this study aimed to explore the diversity and composition of the naturally regenerating tree species at Satchari National Park (SNP), a protected area with high conservation priority in Bangladesh. We found…
Characterisation and lethal dose determination of EMS induced mutation in Gallong jhum rice (Oryza sativa L.)
Corresponding Author : Romel Ahmed (romel-fes@sust.edu)
Abstract :
Chemical mutagenesis has been used to increase genetic diversity in crop plants. Among the chemical mutagens, Ethyl Methane Sulphonate (EMS) is stated to be the most effective and strong mutagen causing a high frequency of nucleotide substitution, as found in different genomes. Determination of mutagenic sensitivity is an important step in the mutation breeding program as it differs with species and varieties. Therefore, an attempt was made in the study to determine the lethal dose (LD50) of EMS for Gallong…
