This study focuses on the source rock, a critical component of petroleum system, within Eastern Fold Belt (EFB) Bangladesh. It aims to assess occurrence and quality rocks by employing comprehensive approach that includes fieldwork, laboratory analysis, seismic interpretation, well data. The research was conducted in Sylhet Khagrachari regions, where prior rock evaluations were inadequate. Organic carbon content evaluation using TOC analysis reveals substantial presence EFB, which can produce...
This study undertakes a spatiotemporal analysis of microplastic pollution in surface beach sediments, covering 7 coastal beaches Bangladesh and two seasons-monsoon winter. The concentration microplastics extracted from the sediment is 242.86 particles/kg dw. results showed both significant seasonal (p value = 0.001) spatial 0.004) variation. abundance polymer types were significantly higher (57 %) winter than monsoon season (43 %). Touristic commercial levels non-touristic beaches....
Post-consumer polyethylene terephthalate (PET) plastic bottles, after some pre-processing, were chemically depolymerized for the production of terephthalic acid (TPA), an important monomer PET resin. The optimized condition hydrolysis was 100°C with 80% v/v aqueous sulfuric liquor 30 min reaction time. acids (TPAs) filtered out from mixtures a sintered glass filter. viscosity recycled measured before it used in successive batch depolymerization. increased gradually 5 mm 2 /s to 87 /s. TPA...
Three strains, MAFF 210191 T , G24103 and G24116, assumed to be members of two novel species, were isolated from several rhizosphere habitats in different parts Japan. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolates formed a distinct monophyletic group together with known species genus Labrys suggesting have close affiliation this genus. In study, polyphasic approach was used characterize compare three monachus methylaminiphilus . All aerobic, Gram-negative,...
We report the effect of controlled particle size (obtained by using 80, 100, 120, 140 and 200 mesh) source materials on synthesis a well-known biomaterial, hydroxyapatite (Hap). In addition to this, we have also mapped consequence applied temperature (700°C, 800°C 900°C) crystallographic properties phase composition obtained Hap. Nevertheless, although with Hap, in each case, β-tricalcium phosphate (β-TCP) was registered as secondary ANOVA test revealed that results parameters are...
Waste poly(vinyl chloride) fill material from the cooling tower of a power plant was used for mechanical recycling. Mechanical recycling is processing plastic waste without changing original chemical structure plastic. The rigid cleaned, grinded and compression molded at optimized conditions time, temperature pressure using molding machine. Virgin purchased by same sheets virgin were characterized attenuated total reflection Fourier transform infrared analyses, tensile properties thermal...
Abstract The nanocellulose and its nanocomposites have significant importance in the most economic sectors of applications. This research involves synthesis from Albizia lebbeck wood sawdust. Quantitative evaluations chemical components present sawdust a native hardwood species were determined by analysis method. results revealed that approximate amount hot water extractives, 96% ethanol alpha-cellulose, hollocellulose, hemicellulose, lignin ash content 6.9%, 7.31%, 40.72%, 65.10%, 24.38%,...
Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely wrack line, beach face, swash zone. This study aims enumerate number polymeric variety microplastics found sediments coastal islands Bangladesh, including Sandwip, Kutubdia, Saint Martin's Island northeastern Bay Bengal. NaCl solution with...
In the vast literature of Bengal famine 1943, it is hard to offer new insights about that vicious source mass misery. Local history may mark a significant departure here, as provides scope for an in-depth study both origin and course famine. Bakarganj was called granary Bengal, which used supply rice other regions even in driest years due its large production. But 1943 gravely affected this district. The present shows how colonial measures played vital role intensifying Bakarganj....
This research covers 7 coastal beaches of Bangladesh and two seasons like monsoon winter for spatiotemporal analysis microplastic pollution in surface beach sediment. 3400 particles/kg microplastics were extracted from the sediment with an average concentration 242.86 dw. The results showed significant seasonal (p value=0.001) spatial value=0.004) variation. abundance, weight polymer types significantly higher value >0.05) than monsoon. Touristic commercial high level non-touristic beaches....

Purpose After the fall of Burma on 10 March 1942 British government extensively implemented scorched-earth policies in Bengal like denial rice and boats. The had inadequate defense equipment to resist Japanese attack Bengal. invasion supply Burmese suddenly stopped. Faridpur district used import from Burma. conquest created an immediate serious crisis for several imported districts coastal Hence, none East could escape its brutal clutches severity recorded Chittagong, Dhaka, Faridpur,...
Citizen’s Charter is one of the important and commendable governance tools in Public Administration Bangladesh. In 2007, Cabinet Division took initiative to introduce different public offices. This study was conducted assess implementation status Ministry field level offices Bangladesh with its challenges. To achieve research objectives, this followed both quantitative qualitative approaches. Sample survey semi-structured questionnaires used for collecting primary data while secondary were...
Abstract In today's world, microplastic contamination of aquatic systems is a subject major concern. this study, the incidence microplastics in freshwater fish from both farmed and wild sources was evaluated. Wild catla ( Gibelion catla) , stinging catfish Heteropneustes fossilis) rui Labeo rohita) tengara Mystus tengara) pabdah Ompok pabda) were collected Padma river, Turag river Bhairab river. Farmed fishes same species Mymensingh Chandpur markets. 68 (43.6%) microparticles out 156...
