The determination of 6-, 8-, 10-gingerol, and 6-shogaol in dried ginger (Zingiber officinale) and in the dried aqueous extract of ginger is reported. This is the first study to report a validated method for the determination of these 4 analytes. Several extraction solvents and methods were examined, and the optimum combination was determined. The samples(More)
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return(More)
Dravet syndrome is a rare and catastrophic type of epilepsy in infants. Acute encephalopathy has been sporadically reported in patients with Dravet syndrome; however, the risk factors for this serious complication have not been identified. We report two patients with a clinical diagnosis of Dravet syndrome who experienced acute encephalopathy initiated by(More)
The objective of this paper is to design, and fabricate an inset fed rectangular microstrip patch antenna. In this paper we tested our design by using the electromagnetic solver, simulator (IE3D), was used to numerically investigate and optimize the proposed antenna configuration. Besides the structure external dimensions, the influence of the various(More)
A validated analytical method is described for the determination of honokiol and magnolol in Hou Po (Magnolia officinalis) as the dried raw herb and the commercially prepared dried aqueous extract. The samples were extracted with methanol by the Soxhlet method, and the extract was analyzed by liquid chromatography with photodiode array (LC/PDA) detection(More)
