The majority of the rural community is engaged in agricultural crop production, cattle farming, and poultry production. To prepare feed for animals, conventional grass-cutting machines are intensively used which do not have a friendly operation. The conventional cutter machine's unsafe design resulted in severe injuries and needed more workforce. Keeping in view the drawbacks of the existing traditional cutter machine, this project has been carried out to design and construct a chaff cutter machine to reduce the risks of severe injuries and increased working efficiency. First of all, the working design (3D modeling) of the chaff cutter machine will be developed to analyze its suitability. The development process to fabricate the chaff cutter machine is then carried out by the National Innovation

With increasing C545T doping concentration, trap sites could lead to the promotion of hole injection and the suppression of electron injection due to the electron-transport-character of Alq3 host for each carriers, as confirmed by hole- and electron-only devices. Direct charge injection of hole carriers from the hole transport layer into C545T dopants and the charge trapping of electron carriers are the dominant process to improve the charge balance and the corresponding efficiency. The shift of the electroluminescence (EL) spectra from 519 nm to 530 nm was confirmed the exciton formation route from Förster energy transfer of host-dopan...

Permaculture has been defined by Mollison as, "A philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless action; and of looking at system in all their functions, rather than asking only one yield of them; and of allowing systems to demonstrate their own evolution." Permaculture is the conscious design and maintenance of agriculturally productive ecosystem which have the diversity, stability, and resilience of natural ecosystem. It is the harmonious integration of landscape and people providing their food energy, shelter and other material and non-material needs in a sustainable way. Three ethics of Permaculture are: 1. Earth care: Provision for all life systems to continue and multiply. Care of earth means care for all living and non-living things: soil, species and their varieties, atmosphere, forests, micro-habitats, animals and water. It means that we human should try not to increase situations in which we destroy or perish the natural functioning of planet earth. The earth supplies us with what we need, and to ensure that we survive and prosper, we need to treat it with consideration and respect.
