The current study pivoted on the numerical simulation of magnetohydrodynamic nanofluid flow through the irregular boundary over the Riga plate with heat radiation, suction/injection. The governing equations of continuity, momentum, and energy are constructed to be nonlinear in nature, based on the current problem. The combination of Quasilinear technique with finite difference method using irregular boundaries has been used to solve the governing equations. The velocity profile is enhanced for incremented values of Hartman number. The thermal radiation parameter due to Rosseland approximations is enhanced for temperature and concentration profiles whereas it declines the heat transfer and mass transfer profiles. Temperature, concentration, and heat transfer rates increase for augmented magnetic parameter values, but velocity and skin friction coefficient profiles show the opposite behaviour. The enhanced values of Biot number along with suction/injection parameter reduces the values of skin friction coefficient. The radiation parameter helps to drop the energy rate in the fluid flow as it reduced the skin friction coefficient values. The upsurged values of the thermal radiation parameter along with electromagnetic parameter decreases the values of the Nusselt number.

The article presents information on the findings of analysis of scoured samples of organic cotton, coloured and Bt cotton fibres in terms of physical properties. It notes that the preparation of textile materials plays an important role in further dyeing and finishing. It discusses the process of alkali scouring using a liquor ratio of 1:20, sodium hydroxide four percent on weight of the material, wetting agent one percent at boil for one hour. It reveals the physical properties of the fibres including fineness, strength elongation, moisture and trash contents.

The chemistry of the imidyl radical generated photochemically from the N‐bromonaphthalenedicarboxamide (II) is studied.
