a novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm cmos technology. a resistive-capacitive feedback is used to extend the bandwidth of the amplifier. as the structure is inductor less, it is suitable for low cost integrated optical interconnects. in this paper improved particle swarm optimization have applied to determine optimal trans-resistance and noise of propose...

The role of dietary fats and oils in human nutrition is one of the most important areas of concern and investigation in the field of nutritional science. The findings of investigations on this subject have wide-ranging implications for consumers, health-care providers and nutrition educators as well as food producers, processors and distributors. New evidence concerning the benefits and risks a...

The mechanism of the self-reaction of HCO radicals is investigated by using high-level quantum-chemical methods including M05-2X, CCSD, CCSD(T) and CRCC(2,3). Next, the rate coefficients for several product channels as a function of pressure and temperature are computed by employing statistical rate theories. Four important product channels are predicted to be CO + CO + H2, HCOH + OH, cis-(HCO)...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

Objective: Most of the research conducted so far on effective treatments for social anxiety disorder has used traditional cognitive-behavioral therapies. However, recent pathological theories emphasize the role of emotion regulation in the formation and continuation of the symptoms of this disorder. Thus, the study has been conducted to compare the efficacy of emotion- oriented therapy and the ...

The process called biohydrogenation occurs mainly in ruminant animals and during it, unsaturated fatty acids, and particularly poly-unsaturated ones (linoleic and linolenic) coverts to a saturated form of stearic acid. For many years, the beneficial effects of biohydrogenation intermediate fatty acids like cis-9 trans-11 linoleic acid, the main natural isomer of conjugated linoleic acids (CLA),...
