Experimental studies on the transmission and tolerance of vertical vibrations, caused by tractors, indicate that the tractor operator is exposed to low-frequency (0.5 to 11 Hz) and high-intensity vibrations, which are harmful to the body, causing disorders of the spine and supporting structures. The intensity of these “harmful” vibrations is reduced by(More)
In this study, the occupant and the tractor were modelled together in the form of a lumpedmass system interconnected by springs and dashpots and the tractor was provided with relaxation suspensions to the front and rear wheels and seat (at the plane of centre of gravity of the tractor). The response of the composite model to vertical vibrations was found by(More)
Thermally stable hydroxyapatite (HAp) was synthesized by hydrothermal method in the presence of malic acid. X-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (SEM), differential thermal analysis (DTA), thermogravimetric analysis (TGA) was done on the synthesized powders. These(More)
Organic NLO material of 2-Aminopyridinium 4-methylbenzoate Dihydrate (2A4M) was synthesized using 2-Aminopyridinium and 4-methylbenzoic acid as starting materials. Single crystals of 2A4M were grown by the slow evaporation solution growth technique at room temperature using water as a solvent. The grown crystal was characterized by single crystal XRD to(More)
Chloro-functionalized mesoporous MCM-41, SBA-15, MCM-48 and KIT-6 were synthesized by co-condensation of 3-chloropropyl-trimethoxy-silane (CPTMS) and rice husk ash sodium silicate solution, which is subsequently grafted with a heterocyclic amine, homopiperazine (HPZ). X-ray powder diffraction and BET analysis of the chloro-functionalized mesoporous silicas(More)
Large pore HY zeolite was modified with phosphoric acid by wet method. The modified zeolite was converted to Na(+) form using aqueous NaHCO(3) solution(.) The Na(+) form of modified zeolite, represented as PNa(2)Y, was characterized by XRD, BET surface area, SEM, and AAS techniques. The XRD analysis showed diffraction patterns same as that of parent HY(More)
