A Study and Report on Assessment of Antibiotic Prescribing Patterns and Drug Resistance Among Various Infectious Diseases in Hospital
Abstract: Antimicrobial resistance remains the biggest cause of death worldwide. According to the World Health Organization, the age standardized mortality due to infectious diseases in India in 2008 was 377 per 100,000 persons, which is considered as highest in South Asia. This has led to the increased prescribing of antibiotics even at unnecessary conditions, which increased the rate of inappropriate prescribing of antibiotics, which in turn resulted in the emergence of …

Evaluation of Antenna Performance using a Novel Measurement Device: Methodology and Results
Abstract: In the last decade, the field of On Chip Antennas (OCA) has experienced unprecedented growth due to the introduction of small, low-cost, low-power System-on-Chip (SoC) wireless communication devices. OCAs are superior to conventional off-chip antennas in a number of ways. They first reduce the overall size of the wireless communication system since the presence of an OCA eliminates the need for an impedance matching network between the antenna and RF …
