An Assessment of Green Messages on the Audience of Dhaka City
(2011-01) Islam, M.S.; Hossain, M.M.; Hassan, R.
Previous research has shown the impact of various message formats on consumer behavior. Much work has been done to ascertain the impact of the various types of appeals (rational, fear, and guilt), and degree of customer involvement on consumer responses to various messages. This research represents a robust study conducted on the impact of messages pertaining to a greener environment on the population of Dhaka City. A structured questionnaire was sent out to 400 respondents within the periphery of Dhaka City. It has been observed that the dependent variable, consumer attitude towards green messages is related to the different appeals of the messages that they are exposed. In addition, it has also been found that consumers attitude towards green messages is influenced by their degree of involvement pertaining to various environmental issues.

(Academic Press, 2024-02-04) Hossain, M.M.; Walid, M.A.A.; Walid, M.A.A.; Galib, S.M.S.; Azad, M.M.; Rahman, W.; Shafi, A.S.M.; Rahman, M.M.
Diagnosis of COVID-19 positive patients is the eventual move to impede the expansion of coronavirus. Variations of coronavirus make it tough to recognize COVID-19 positive patients through symptoms. Hence, this research aims at a faster and automatic detection approach of COVID-19 disease from the chest Computed tomography (CT) scan images. For the composition of the system, this approach constructs a feature vector from the CT images through the features fusion of two Convolutional neural network (CNN) models namely VGG-19 and ResNet-50. Before the feature fusion, preprocessing techniques are applied to gain more accurate outcomes. Moreover, pertinent features are identified from the feature vector by using several feature optimization methods namely Recursive feature elimination (RFE), Principal component analysis (PCA), and Linear discriminant analysis (LDA), and among them, we have observed PCA as the best preference. Classification is performed on the optimized feature utilizing the Max voting ensemble classification (MVEC). The fused features of VGG-19 and ResNet-50, processed with PCA and MVEC, provide the best outcomes of accuracy, specificity, sensitivity, and precision at 98.51 %, 97.58 %, 99.49 %, and 97.47 %, respectively, after 5-fold cross-validation for the proposed method.

The efficacy of rare-earth doped V2O5 photocatalyst for removal of pollutants from industrial wastewater
(Scopus, 2024-01) Kabir, M.H.; Hossain, M.Z.; Jalil, M.A.; Ghosh, S.; Hossain, M.M.; Ali, M.A.; Khandaker, M.U.; Jana, D.; Rahman, M.M.; Hossain, M.K.; Chowdhury, J.; Kazi, Mohsin
Photocatalysis is regarded as one of the most environmentally benign methods of mitigating the effects of textile wastewater. Despite the fact that various semiconducting metal oxides are used in photocatalysis, their performance is still insufficient. In this study, the hydrothermal method was used to synthesize rare-earth (RE) elements [Holmium (Ho) and Ytterbium (Yb)] doped vanadium pentoxide (V2O5) to improve its photocatalytic efficiency. The effect of RE ions on the photocatalytic efficiency of doped V2O5 has also been analyzed from both the experimental and first-principle density functional theory (DFT) methods. The stable orthorhombic crystal structure of doped V2O5 is confirmed by the X-ray diffraction with no secondary phase, and high-stressed conditions are generated for the 3 mol.%. The crystallite size, strain, and dislocation density are calculated to perceive the doping effect on the bare V2O5. The optical characteristics have been measured using UV–vis spectroscopy. The absorptions are found to be increased with increasing doping concentrations; however, the bandgap remains in the visible range. The photocatalytic properties are examined for the bare compound with varying pH, with the highest efficiency exhibited for pH 7. Moreover, it is observed that the RE ions significantly impact the catalytic behavior of V2O5. The degradation efficiency is improved by 93 % and 95 % for the 3 mol.% of Ho and Yb-doped V2O5 samples within 2 h, respectively, and the mechanism behind these extraordinary efficiencies has been explained thoroughly.
