Not AvailableIn the manufacture of tablets, tableting processes, design of reliable solids handling equipment such as hoppers, silos, and storage bins the
flowability of powders and other flow property data are most important characteristics. In the case of powder discharge from silos or
hoppers, arches and ratholes may be formed, especially in the presence of humid air, resulting in poor flow of the powder. Keeping in this
view flow properties of gum arabic powder was evaluated by powder flow tester in which gum arabic powder with particle size 700 micron
to 300 micron was tested. It was found that gum arabic powder follow two type of flow behaviour first easy flowing between 0.6 to 3 kPa
major principal consolidating stress, Ï1 and 0.07 to 0.30 kPa unconfined faliure strength, Ïc then free flowing between 3 to 9 kPa major
principal consolidating stress, Ï1 and 0.30 to 0.80 kPa unconfined faliure strength, Ïc. The critical arching values for gum arabic were
density 717.3 kg/m3, effective angle of internal friction 38oC, effective lengh 0.011m at stress level 0.038 kPa and critical rathole values were
density 797 kg/m3, effective angle of internal friction 36.5oC, diameter 0.29 m at stress level 0.80 kPa. All these properties can be used in
handling and processing equipments.Science & Technology Society for Integrated Rural Improvemen

Not AvailableThe increasing demand for crop production, given worldwide increases in the human population, puts pressure on moving natural resources towards sus-tainable development. This creates a big challenge for the upcoming generation. If improvement is not successful, there exists the unfortunate consequence that global food production may soon become insufficient to feed all of the worldâs people. It is therefore essential that agricultural productivity be significantly increased in a more sustainable and environmentally friendly approach. Plant-beneficiary rhizo-bacteria (PBR) naturally activate microorganisms found in the soil. Because they are inexpensive, effective, and environmentally friendly, PBR are gaining impor-tance for use in crop production by restoring the soilâs natural fertility and protect-ing it against drought and soil diseases, thereby stimulating plant growth. PBR decrease the use of chemical fertilisers, pesticides, and artificial growth regulators; the intensive use of these inputs has led to severe health and environmental hazards, such as soil erosion, water contamination, pesticide poisoning, decreased ground-water table, water logging, surface crusting and depletion of biodiversity. The use of PBR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism with the aim of sustaining soil health over the long term.
