A quartz crystal microbalance has been used to monitor the polymer production of a bacterial population in liquid medium. The increasing amount of produced polymer corresponds to an increase in the viscosity of the liquid, which is directly measurable as the fluid contacts the surface of the quartz crystal in the sensor system. This procedure is being developed as a novel method for measuring m...

The velocity of a liquid flowing through the core of a hollow core photonic crystal fiber (driven by capillary forces) is used for the determination of a liquid's viscosity, using volumes of less than 10 nl. The simple optical technique used is based on the change in propagation characteristics of the fiber as it fills with the liquid of interest via capillary action, monitored by a laser sourc...

Background & Aims of the Study: A feed forward artificial neural network (FFANN) was developed to predict the efficiency of total petroleum hydrocarbon (TPH) removal from a contaminated soil, using soil washing process with Tween 80. The main objective of this study was to assess the performance of developed FFANN model for the estimation of   TPH removal. Mater...

Title: Whole blood viscosity in individuals with insulin-dependent diabetes mellitus: Exploring the role of the porous bed viscometer Objective: The study was performed to evaluate the capacity of a porous bed viscometer (PBV) to demonstrate differences in blood viscosity in patients with diabetes mellitus and to investigate the • role that various cellular and plasma components play in determi...

Introduction: Gluten is a protein found in grains.  Research has shown that the gluten that is in grains of wheat, barley, rye, and oats (to a lesser degree) is toxic to many individuals.  While gluten is essential for the make-up of these 4 grains, our bodies do not need it. Is it healthful?  The protein in today’s wheat is poorly digested and can be harmful.  An estimated 95% of prepared fo...
