Sachet water has become an important primary source of drinking water in western Africa, but little is known about bacteriologic quality and improvements to quality control given the recent, rapid evolution of this industry. This report examines basic bacteriologic indicators for 60 sachet water samples from two very low-income communities in Accra, Ghana, and explores the relationship between ...

This paper investigates a simple mathematical model for water level system, which consists of DC motor (water pump), and Speed to Height transformation block, that relates the speed motor, height level. The input signal is applied voltage armature while output rotational shaft. A modified model-free adaptive controller suggested, control water, by adjusting rate incoming flow container, changin...

With an aim to control the surface hydrophobicity and water adhesion, as observed on various natural surfaces, novel 3,4-propylenedioxythiophene (ProDOT) monomers having one two 3-trimethylsilylpropyl (TMS) groups were synthesized subjected electropolymerization form coatings. The monomer ProDOT is employed owing its tendency fibrous structures by [T. Darmanin, F. Guittard, Mater. Chem. Phys. 1...
