Residual film method

This study analyses the hydrodynamic characteristic of the tilting pad thrust bearing. Research content is simultaneously solving the Reynolds equation, force equilibrium equation, and momentum equilibrium equations. Reynolds equation is solved by utilizing the finite element method with Galerkin weighted residual, thereby determines the pressure at each discrete node of the film. Force and momentums are integrated from pressure nodes by Gaussian integral.

The insecticidal and repellent activities were observed by residual film method and surface film application methods respectively. Leaf, stem and root of Mimosa pudica L. were screened through Petroleum ether, chloroform, ethyl acetate and methanol extracts against flat grain beetle, Cryptolestes pusillus (Schon.).

The present study was carried out to determine the synergistic effects of edible oils (Palm, sunflower, cotton seed, rice bran, castor, sesame) and non-edible oils (Neem, pongamia, citronella, rosemary, thyme, jatropha and lemongrass) in the suppression of malathion resistance Sitophilus oryzae (L.) and Tribolium castaneum (Herbst.) by adopting residual film method. Among edible oils, sesamum exhibited high level of malathion resistance suppression in S. oryzae with SR of 74.

The laboratory experiment was conducted at RARI, Durgapura during rabi 2017 to find out the toxicity of insecticides, bio-pesticides & plant product against H. armigera were reared on gram leaves and pods as well as on artificial diets. The nucleus culture of H. armigera was maintained in the laboratory under controlled conditions (26 _+2°C and 80 +- 5 percent RH). The 12 days old larvae of H. armigera use as a test insect by residue film method for bioassay.
