This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

nanostructured zinc oxide (zno) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. zno nanoparticles were synthesized by co-precipitation method. zno nanoparticles were synthesized using zn(no3)3 and k2co3 precursors. the structure of the obtained product was confirmed by the powder x-ray diffraction (xrd) anal...

Sphere-like shaped cobalt oxide nanoparticles (Co3O4) were synthesized by a simple wet chemical method using cobalt chloride as precursor and cetyl trimethylammonium bromide (CTAB) as surfactant. Their structural and surface morphologial properties were characterized by high resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM) and X-ray diffra...

horse shoe shaped lipoma of the upper extremity is a very rare entity. we present a case of 45 years old female who presented with painless progressive swelling over the distal forearm and tingling and numbness over the ulnar nerve territory. mri and surgical exploration showed a horse shoe shaped multilobulated lipoma encasing the distal ulna. the mass was excised in toto, and the sensory alte...
