Idiopathic granulomatous hepatitis is a rare disease of unknown cause that is characterized by recurrent fevers and granuloma in the liver. Attempts to define an exact etiology of the fever of granulomatous hepatitis frequently do not yield a precise diagnosis. Idiopathic granulomatous hepatitis was confirmed after a thorough work up and negative cultures and serologies were obtained, and in the absence of another condition that could lead to granulomas in the liver.We have experienced a 67-year-old female patient who presented with prolonged fever for 2 months and revealed granuloma in liver biopsy. She was treated with glucocorticosteroid and defervescence resulted.

In this paper, a miniature folded dipole is proposed for designing a metal-mountable UHF RFID tag. The proposed tag antenna is low in profile and has a compact size of 40 mm × 40 mm × 3.1 mm (0.122λ × 0.122λ × 0.009λ). Folding the dipole arms into a twofold rotational symmetrical style can miniaturize the tag footprint for achieving high compactness. It has been found that the capacitive coupling mechanism between the rotational symmetrical radiating arms is effective in enhancing the vertical radiation, which subsequently improves the achievable read distance in the boresight direction. Also, an incorporated circular loop can provide additional inductance for achieving good impedance matching with the RFID chip. For the proposed tag antenna, a full ground plane is inserted underneath the radiator for isolating it from the backing metal, making the tag tolerant to the metallic platform. The proposed tag antenna is able to achieve a maximum read distance of 7 m at 4 W EIRP when it is tested on metal.

This paper discusses the used of an optical interferometry technique for bending and torsional vibrational modes measurement. With this technique, the amplitude and frequency of the vibrations involved in tabletop of a home-made optical table were measured. Besides, vibrational modes involved and performance of the damping system were determined. Keywords -Optical interferometry; bending and torsional vibrational modes; vibration amplitude measurementI.
