Water is a major media for carrying the cause of illness in the world and particularly in rural communities. The objectives of this study were to evaluate access to safe drinking water, water purification techniques and waterborne disease incidence in tribal region of Visakhapatnam District. 100 households were randomly selected with structured interview questions being administered in the four...

Water is a necessary part of life, but without proper filtration, it could cause problems such as illness or death. While citizens of developed countries may take the water that flows from their taps for granted, many parts of the world do not have access to clean water. A small village in Thailand called Nong Bua is one such community that is hindered by the quality of their water supply. Nong...

Rainwater was contaminated by a large release of radionuclides into the environment during the Fukushima Daiichi nuclear disaster. It became a matter of concern for Japan when several water purification plants detected ¹³¹I contamination in the drinking water. In the present study, the decontamination efficiency of two easily obtainable commercial water purifiers were examined for rainwater con...

Traditional techniques for calculating control limits for processes with discrete responses are based on the Poisson distribution. However, for many processes, the assumption of a Poisson distribution is violated. In such cases, use of traditional Poisson control limits may result in an inflated risk of Type I error. The negative binomial distribution is a natural extension of the Poisson distr...
