Development of measurement apparatus for expansion and shrinkage during setting, using a non-contact micro displacement meter.

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Development of a Fiber based Interferometric Sensor for Non-contact Displacement Measurement

In this paper, a fiber based Fabry-Perot interferometer is proposed and demonstrated for a non-contact displacement measurement. A piece of micro-prism which attached to the mechanical vibrator is served as the target reflector. Interference signal is generated from the superposition between the sensing beam and the reference beam within the sensing arm of the fiber sensor. This signal is then ...

Development of on - machine measurement system for micro - factory – Contact and non - contact combined probe – Ichiro Ogura

A new micro-respirometer with automatic setting and recording apparatus.

The instrument was designed to measure the O2 uptake of living material which consumes between o-oi and 5-0 yl. O2/ hr. Its accuracy is +o-ooi /u.1., and it has the following advantages over other micro-respirometers of similar sensitivity. (a) It is robust, easy to handle and is suitable for routine use. (b) The respirometer constant is independent of the gas volume of the reaction vessel. (c)...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
