BACKGROUND Holocarboxylase synthetase (HCS) catalyzes the covalent binding of biotin to both carboxylases and histones. Biotinylated carboxylases and biotinylated histones play crucial roles in the metabolism of fatty acids, amino acids, and glucose, and in gene regulation and genome stability, respectively. HCS null mammals are not viable whereas HCS(More)
A novel wide band switched line phase shifter for the frequency range of 800MHz to 1200 MHz is proposed in this paper. Pin diodes are used for switching the signal between two transmission lines to achieve the desired phase shift. The wide band phase shift is achieved by varying the capacitance of the transmission line using pin diode to vary the(More)
A novel wide band hybrid ring coupler is proposed in this paper. The change in length of transmission line is calculated and it is converted in to equivalent impedance. Impedance of the circuit is varied using variable capacitor. The device is to be fabricated and tested for frequency range 800-1200MHz. The circuit shows improved isolation and return loss.(More)
