IoT based real-time water quality monitoring system in water treatment plants (WTPs).

This study presents the development and implementation of an Internet of Things (IoT)-based real-time water quality monitoring system tailored for water treatment plants (WTPs). The system integrates advanced sensor technologies to continuously monitor key water quality parameters such as pH, dissolved oxygen (DO), total dissolved solids (TDS), and temperature. Data collected by these sensors is transmitted through a robust communication network to a centralized monitoring platform that utilizes cloud-based storage and analytics.

Usefulness of self ligation mediated polymerase chain reaction: a rapid method for fingerprinting in molecular epidemiology of tuberculosis.

Restriction fragment length polymorphism (RFLP) analysis based on the insertion sequence IS 6110 has been used as one of the powerful tools for epidemiological study of tuberculosis. However this technique requires more than 1 micro-gram of DNA and two days for completion. To overcome these inconvenience, we have modified a PCR-based method, self ligation mediated PCR (SL-PCR) on the molecular epidemiological study.

Molecular cloning and characterization of the gene coding for azoreductase from Bacillus sp. OY1-2 isolated from soil.

Azo dyes are regarded as pollutants because they are not readily reduced under aerobic conditions. Bacillus sp. OY1-2 transforms azo dyes into colorless compounds, and this reduction is mediated by a reductase activity for the azo group in the presence of NADPH.

Public health services in Bangladesh with special reference to systems and trends of vital statistics.

Health is one of the basic requirements for improvement in the quality of life. Since Bangladesh became independent, a policy for providing essential minimum health care to all has been actively pursued.An overview of Public Health Services in Bangladesh is presented in terms of: (1) a profile of the country, (2) an overview of public health, (3) medical care, and (4) environmental health.
