Bubble dynamics and interface phenomenon

  The dispersion of gas into liquid is a complex part and it is depending on bubble size and its distribution including coalescence and breakup. The study of flow pattern, bubble size and its distribution and factors affecting the bubble size was reviewed by several authors. Various measurement techniques of bubble size are also reported in literature. In this paper we have made an attempt to show the...

Modelling some ergonomic parameters with machine parameter using hand powered maize sheller

  The economic situation in most developing countries have left farmers and processors operating at the small scale, hence the use of automated and electric power driven equipment is limited to the few large scale processors. The effect of the ergonomic parameters namely; weight, age, height and arm length in relation to the resulting efficiencies; shelling efficiency, cleaning efficiency, mechanical damage and...

Development of a realtime microcomputer-based logging system for diagnosis and research

  In this research, a realtime temperature logging system that logs human temperature into the computer over a period was developed and the temperature chart produced is useful for diagnosis and research purposes. The graphical representation within the threshold temperature (36°C) depicts normal body temperature of a healthy person. An upshot beyond this temperature makes the logger to signal an audible...
