BACKGROUND Transnasal endoscopic repair has become the treatment of choice for most anterior cranial and all sphenoid sinus breaches. The aim of this paper is to evaluate the results of endoscopic management of cerebrospinal fluid (CSF) rhinorrhea in a tertiary care center in South India. MATERIALS AND METHODS A retrospective analysis of 40 consecutive(More)
— — In this Paper implementation of an add-on interaction system for motorcycle is implemented using wireless helmet. The system consists of a vehicle-to-driver, vehicle-to-traffic signal, vehicle to speed breaker communication mechanism, which is based on a ZigBee technology. The system is focused to increase the safety level of a motorcycle, a compact(More)

—Advanced dual-band stepped-impedance resonator filters are prototyped and their performances verified. The main advantages compared to traditional designs consist in two controllable passbands at desired frequencies, which is achieved by utilizing all-electric coupling, wide stopband regions towards higher frequencies and relatively small circuitry.(More)
The main objective of Industrial pollution monitoring system using LabVIEW and ZIGBEE is to determine the quality of effluent management and working environment of industries, to know the key descriptors to be considered in pollution monitoring system and send the information to Pollution Control Board (PCB) and public. The majority applications of(More)

In air crafts, missiles and ships, during their motion, the sensors are prone to undergo lot of vibrations and shocks. Because of their sensitivity to these environments they malfunction. In order to avoid this situation all the sensors are modelled and analysed at the ground for different parameters viz. temperature, vibration and shock etc. A Ring Laser(More)
Echo cancellation is one unavoidable module in any voice related communication systems such as telephone, mobile and VOIP. In several applications run time high speed echo cancellation can give better quality of service. Real time echo cancellation is an important feature for hands-free operation of telecommunication equipment like mobile phones. A(More)

A simple, precise and accurate RP-HPLC method was developed and validated for rapid assay of Carbidopa in tablet dosage form. Isocratic elution at a flow rate of 1.0ml/min was employed on a symmetry C18 (250x4.6mm, 5µm in particle size) at ambient temperature. The mobile phase consisted of methanol: KH2PO4: 75:25 (V/V). The UV detection wavelength was 262(More)
A comparative study on the biochemical parameters in hydatid cyst fluids of sheep, goats, camels, cattle and human cystic forms of Echinococcus granulosus has been made in Libya. Quantitative variations in the levels of sodium, potassium, calcium, cholesterol, glucose, urea, creatinine and gamma glutamyl transpeptidase (gamma GT) were found in the cystic(More)
