Aluminium alloy based metal matrix composites are being extensively used in the aerospace, automobile, defense, marine and electronic industries owing to their excellent strength, high resistance wear, corrosion better thermal stability. Many investigators have explored different aluminium series composites, like heat treatable AA2024, AA6061 AA7075 since properties of these alloys can be easil...
recent studies in scientific education as well as foreign and second language instruction suggest that thinking has rarely been an integral part of education and training in classroom. some scholars decried the lack of emphasis on thinking in the institutes and schools. they noted that memorization and drills were rewarded,while inquiry, reflection, and consideration of alternatives were frowne...
Polycrystalline samples of Nd1-xCaxBa2-xLaxCu3O7-δ (with 0.0 ≤ x ≤ 0.15) were prepared by the standard solid state method. The transport and superconducting properties have been studied by the resistivity and thermoelectric power measurements as a function of temperature and doping concentration. With increasing doping concentration, the resistivity was increased and thermoelectric power was c...
