BACKGROUND The epidemiological aspects and diagnostic problems encountered in a rural set up are largely unknown. The present study on cutaneous tuberculosis encompassing clinical, pathological and epidemiological aspects was undertaken at Rajah Muthiah Medical college and Hospital (RMMC&H), a teaching hospital mainly catering to the health needs of a(More)
LTE-A as a cellular technology has gained tremendous importance in recent years due to its high data-rates and improved data access for mobile devices. Recently, utilizing the unlicensed band as a supplementary band for LTE-A is being considered to expand the capacity of mobile systems. Licenseassisted access using LTE (LAA-LTE) will thus operate in the(More)
A group of 420 elderly people (163 women and 257 men with a mean age of 65 years) from urban and rural populations in India were selected for the study. The caloric intake of 93.3% was less than the recommended allowance, the mean daily caloric intake being 1191 kcal in men and 928 kcal in women. Except for calcium, all nutrients were deficient in their(More)
OBJECTIVE The objective of the following study was to assess the knowledge, practice, perception and adverse reactions among hair dye users. SETTINGS AND DESIGN A cross-sectional study was conducted on patients, their attenders and staff of SDUMC. MATERIALS AND METHODS A questionnaire (28) pertaining to use of hair dyes and reactions to them was(More)
In this work, we focus on the problem of source addressing in multiple source single receiver bacterial communication network. We propose amplitude-addressing, where the amplitude of transmitted signal is assigned as address of the source. We analyse the performance of the network with different addressing mechanisms and propose an optimum address sequence(More)
We present nanoNS3, a network simulator for modeling Bacterial Molecular Communication (BMC) networks. nanoNS3 is built atop the Network Simulator 3 (ns-3). nanoNS3 is designed to achieve the following goals: 1) accurately and realistically model real world BMC, 2) maintain high computational efficiency, 3) allow newly designed protocols to be implemented(More)
In this work we consider nano-scale communication using bacterial populations as transceivers. We demonstrate using a microfluidic test-bed and a population of genetically engineered Escherichia coli bacteria serving as the communication receiver that a simple modulation like on-off keying (OOK) is indeed achievable, but suffers from very poor data-rates.(More)
