Treatment of milk wastewater using up-flow anaerobic packed bed reactor

An up-flow anaerobic packed bed (UAPB) bioreactor has been designed on a laboratory-scale and used for treatment of domestic milk wastewater (MWW). The UAPB bioreactor was operated under mesophilic temperature (37-45°C) and reactor performance evaluated at various organic loading rates of MWW effluent at hydraulic retention times (HRT) of 1, 2, and 3 d based on the removal of organic matter COD, BOD, SS, pH changes and biogas production. The kinetic parameters were estimated using the experimental data to develop a reactor model. Empirical relations were generated for the characteristics like COD, BOD, and SS using modeling equations. This study proved that the UAPB reactor performance is excellent for treating domestic MWW and easily biodegradable dairy wastewater influent. Hence, this system can operate at low costs, making it suited for use in the developing countries and rural areas

A Review: Real TIME Ecg Transmission Via Wireless Communication

India has need to access a specialist care and advice in rural and remote areas. Wireless communication System aims to fill up this gap. It is not necessary for the doctor to be physically present at the hospital centre, as it is required with most of the existing telemonitoring systems. One of the most widely used methods to test the human health condition is to measure his/her ECG. In this paper we propose and built an ECG monitoring system that can measure user's ECG using wireless communication. The actual system will consist of ECG electrodes, amplifying circuitry and data acquisition i.e. data collection then transmission of data through wireless network

Overview of a Home Multi-tasking Robot System for the Elderly and Disabled

Robotics is developed very rapidly in the last two decades. Robotics has found wide range of applications in today’s world. The development of technology has opened the new doors for the replacement of human by the machines. The robotics development is not only limited to the military applications but it has found several applications in domestic purposes also. The research was started with the basic robot model in 1961 from the metal pieces connected together; today it results in the replacement of the human by robot. The robots have optimized many industrial applications and have provided the better efficiency by reducing the errors and the time requirements. In this manuscript, authors have presented the overview of the research carried out on the robot systems utilised for the elderly and disabled human beings
