A simple and sensitive high-performance liquid chromatography method with ultraviolet (UV) detection has been developed and validated procedure was developed for simultaneous determination of Cefixime and Dicloxacillin in tablet dosage form by reverse phase C18 column (water symmetry C18 5μ, 250mm x 4.6mm). The mobile phase used as combination of Acetonitrile: Potassium dihydrogen Phosphate in the ratio of 60:40 (pH adjusted to 6.0 with potassium hydroxide). The detection of the combined dosage form was carried out at 220 nm and flow rate of 1.0 ml/min. The retention time for Cefixime and Dicloxacillin was found to be 2.027 and 3.249 min respectively, and recoveries from combined dosage form were between 98% to 102%. Linearity obtained in the concentration ranges from 60, 80, 100, 120, 140% Cefixime and Dicloxacillin with correlation coefficient of 0.9991 and 0.9996 respectively. The method herein described was successfully applied for the evaluation of Cefixime and Dicloxacillin combined dosage form.Keywords

Solar coronagraph mimics total solar eclipse by blocking the solar disk and enabling the observation of extended coronal atmosphere of the Sun. Visible Emission Line Coronagraph (VELC), on-board Aditya-L1 space mission, is an internally occulted solar coronagraph capable of simultaneous imaging, spectroscopy and spectro-polarimetry close to the solar limb. This payload is designed to study the coronal plasma and heating of the solar corona. Studying development, dynamics and origin of coronal mass ejections and measurement of coronal magnetic fields over active regions are other important science goals. VELC is designed to image the solar corona at 500 nm with an angular resolution of 5" over a field of view (FOV) of 1.05-3 Ro. It also facilitates simultaneous multi-slit spectroscopy at three emission lines, viz. Fe XIV (530.3 nm), Fe XI (789.2 nm) and Fe XIII (1074.7 nm) with a spectral resolution of 28 , 31 and 202 mÅ/pixel respectively, over an FOV of 1.05-1.5 Ro. The payload has a dual-beam spectro-polarimetry channel for magnetic field measurements at 1074.7 nm.Keywords
