BACKGROUND Throughout Indonesia, thyroid cancer is one of the ten commonest malignancies, with papillary thyroid carcinoma (PTC) in our hospital accounting for about 60% of all thyroid nodules. Although fine needle aspiration biopsy (FNAB) is the most reliable diagnostic tool, some nodules are diagnosed as indeterminate and second surgery is common for PTC.(More)
A class of novel N-((2'-(1H-tetrazol-5-yl)biphenyl-4-yl)methyl)-substituted sulfonamide 3(a-f) and methyl (2'-(1Htetrazol-5-yl)biphenyl-4-yl)-substituted carbamate 5(a-d) derivatives were synthesized from (2'-(1H-tetrazol-5-yl)biphenyl-4-yl)methanamine, an important drug intermediate and using pharmacologically active functionalized sulfonyl chlorides and(More)

This paper audits FM detectors using non-conventional energy based demodulators. The conventional FM demodulators using diodedetector and square-law are also presented. Simulation results give encouraging results regarding demodulation capabilities of the system. A new method of implementation of a diode detector circuit is proposed using MATLAB SIMULINK.(More)
Thinned phased array antenna is useful for Radar and satellite communications. Main drawback of phased array antenna is generation of side lobes and grating lobes when the beam is titled from broadside direction toward the end-fire direction. This paper reports the optimization of thinned phased array antenna using genetic algorithm (GA). By varying the(More)
