Multilevel DRAM (MLDRAM) increases the storage density of DRAMs by using more than two data signal levels in the storage cells. An operational 19200-cell MLDRAM in 1.8-V, 0.18-µm mixed-signal CMOS is described that allows 1, 1.5, 2, 2.25 and 2.5 bits-per-cell operation using 2, 3, 4, 5 and 6 data signal levels, respectively. The MLDRAM uses reference and(More)
Gymnema sylvestre (R.Br.) is an important diabetic medicinal plant which yields pharmaceutically active compounds called gymnemic acid (GA). The present study describes callus induction and the subsequent batch culture optimization and GA quantification determined by linearity, precision, accuracy, and recovery. Best callus induction of GA was noticed in MS(More)
In this work it is proposed to provide proper nutrition to soil, which is very essential for satisfactory crop growth and production. The use of soil tests can help us to determine the status of available nutrients in soil, this paper aims at calculating required amount of NPK fertilizers for soil accordingly NPK levels actually found during soil test.(More)
