Among expert scientists and politicians, there is increasing agreement that it is absolutely necessary to reduce the emission of greenhouse gas (GHG) to lessen the severity of climate change. Although little, renewable energy sources currently reduce GHG that are being emitted from the energy industries. According to the majority of long-term energy estimates, renewable energy will be a substantial addition to the supply of energy worldwide by the end of this century, as capacity of renewable energy is gradually increasing in the early decades. However, developing nations like Bangladesh are largely reliant on pricey imported energy supplies (coal, gas, and oil) that lay a heavy weight on the country’s economy. Also, air pollution growing in importance as a national and international environmental issue. Regarding the development of clean and sustainable energy, renewable energy sources seem to be among the most practical and efficient alternatives, in both Bangladesh and globally. The geographic advantages of Bangladesh allow for widespread usage of the majority of such renewable energy sources. The comparative potential and use of fossil fuels against renewable energy sources globally and in Bangladesh is explored in this review.

The rise of fake news on social media has had a detrimental effect on society. Numerous performance evaluations on classifiers that can detect fake news have previously been undertaken by researchers in this area. To assess their performance, we used 14 different classifiers in this study. Secondly, we looked at how soft voting and hard voting classifiers performed in a mixture of distinct individual classifiers. Finally, heuristics are used to create 9 models of stacking classifiers. The F1 score, prediction, recall, and accuracy have all been used to assess performance. Models 6 and 7 achieved the best accuracy of 96.13 while having a larger computational complexity. For benchmarking purposes, other individual classifiers are also tested.

The experiment was conducted at Plant Genetic Resources Centre, Bangladesh Agricultural Research Institute (BARI) and the genotypes were collected from Chapainawabganj, the most mango variability rich district in Bangladesh. The molecular characters of mango germplasm were assessed by using six simple sequence repeat (SSR) markers. Polymerase chain reaction (PCR) amplification of the DNA isolated from 60 mango germplasm with 6 SSR primers was performed. The sizes of the alleles detected ranged from 112 to 221 bp. SSRs exhibited moderate values of polymorphic information content (PIC) range of 0.9405 to 0.6501. Genetic distances (D) between varieties were computed from combined data of the 6 primers, ranging from 0.5000 to 1.0000. Moderate degree of genetic diversity was obtained where the highest level of gene diversity value was noted 0.9433 in loci MIGA179 and the lowest level of gene diversity value was computed 0.6683 in loci MIGA253 with a mean diversity of 0.8842. The dendrogram generated from the unweighed pair group arithmetic average (UPGMA) cluster analysis broadly placed 60 mango cultivars into ten major clusters. The cluster size varied from 1 to 12 and cluster-VI was the largest cluster comprising of 9 cultivars. The tendency of clustering among mango cultivars revealed that they have strong affinity towards further breeding programme.
