A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

vitamin e (alpha-tocopherol) is a potent and natural antioxidant. vitamin e is concentrated from soybean oil. the committee on fetus and newborn of the academy of the american of pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. human infants are born with low stores of vitamin e, thus they require an adequate intake of vitamin e soon after birth. the optimum intra...

With a major proportion of research on Electronic Commerce (EC) undertaken on large corporations, and focused primarily on developed countries, little is known about the determinants of EC in Small and Medium-sized Enterprises (SMEs) of developing nations. This chapter explores the extent of EC use by SMEs, and provides some empirical evidence of how internal factors of firm and owner are influ...
