Nanofibrillated cellulose from biomass has recently gained attention owing to their biodegradable nature, low density, high mechanical properties, economic value and renewability. Although they still suffer from two major drawbacks. The first challenge is the exploration of raw materials and its application in nanocomposites production. Second one is high(More)
This study deals with the fabrication of composite matrix from saw dust (SD) and recycled polyethylene terephthalate (PET) at different ratio (w/w) by flat-pressed method. The wood plastic composites (WPCs) were made with a thickness of 6 mm after mixing the saw dust and PET in a rotary type blender followed by flat press process. Physical i.e., density,(More)
Background Lower-riparian Bangladesh and upper-riparian India share more than 50 international rivers (Adel 2012: 528; Riaz 2011: 106; Islam 1992: 204; Ahmed 2012: 51; Afroz and Rahman 2013: 100).1 Needless to say, historically these rivers are very important, playing a vital part in many ways in people’s lives, such as, in agriculture and fisheries,(More)
The study was undertaken to evaluate some chemical parameters of powder milk available in Mymensingh town. Powder milk samples of six different brands namely Kwality, NIDO, Diploma, Anchor, Farmland & Starship were collected from local market. Powder samples were analyzed to know the chemical (P, acidity, fat, protein, lactose, ash, moisture,(More)
The founder stock of a captive breeding program is prone to changes in genetic structure due to inbreeding and genetic drift. Genetic characterization of the founder population using suitable molecular markers may help monitor periodic changes in the genetic structure in future. To develop benchmark information about the genetic structure we analyzed six(More)
River pollution has been one of the main topics in the environmental issue of urban Dhaka, the capital city of Bangladesh. This study was conducted to find out the pollution situation of Turag river and the health problem of the surrounding residents. The results clearly determine that the water quality of Turag river may not be in a position to sustain the(More)
Copper azole type B (CAz-B) preservative and polyphosphatic carbamate (PPC) fire retardants were impregnated in succession into green (97% MC) and kiln-dried (18% MC) Japanese cedar (Cryptomeria japonica (L.f.) D.Don) lumber by the passive impregnation method to prolong the period of lumber use by increasing its resistance to fire and biological(More)
In this study, a green composite was produced from Oil Palm Trunk Lumber (OPTL) by impregnating oil palm shell (OPS) nanoparticles with formaldehyde resin. The changes of physical, mechanical and morphological properties of the OPS nanoparticles impregnated OPTL as a result of natural weathering was investigated. The OPS fibres were ground with a ball-mill(More)
