A 100 A, 100 kHz Transconductance Amplifier
A high-current, wide-band transconductance amplifier is described that provides an unprecedented level of output current at high frequencies with exceptional stability. It is capable of converting a signal voltage applied to its input into a groundreferenced output rms current up to 100 A over a frequency range from dc to 100 kHz with a useable frequency extending to 1 MHz. The amplifier has a ...
متن کاملVitiligo and auto immune diseases: A survey of 100 patients
Vitiligo is an autoimmune skin disease which is characterized by depigmented patches due to loss of pigment cells. Evidence suggests that cell-mediated immunity plays a role in melanocyte destruction while some patients have antibodies to melanocytes or melanocytic proteins. Vitiligo is strongly associated with a number of autoimmune disorders. Autoimmune thyroiditis is the most prevalent disea...
متن کاملConstruction of a Synthetic Vector for Preparation of a 100 Base Pair DNA Ladder
DNA size markers are widely used to estimate the size of DNA samples on agarose or polyacrylamide gelelectrophoresis (PAGE). DNA markers can be prepared by mixing PCR products with definite sizes.Alternatively, they are prepared by restriction enzyme digestion of the genomic DNA of bacteriophages ornatural and synthetic DNA plasmids. The present study describes engineering of ...
