REFERENCE MATERIALS AND THEIR USE

Enzyme reference materials: their place in diagnostic enzyrnology

Estimations of the activities of various enzymes in clinical samples are routine tasks for clinical chemists. Most of this work is done by automatic analysis. The reference ranges against which patients' results are interpreted, however, have generally been defined in terms of manual methods and the conditions of a manual method cannot be reproduced in automated systems. This paper describes th...

MEDICAL USE OF CERAMIC MATERIALS

On magnetostrictive materials and their use in adaptive structures

Magnetostrictive materials are routinely employed as actuator and sensor elements in a wide variety of noise and vibration control problems. In infrastructural applications, other technologies such as hydraulic actuation, piezoelectric materials and more recently, magnetorheological fluids, are being favored for actuation and sensing purposes. These technologies have reached a degree of technic...

the relationship between iranian efl learners beliefs about rote learning, their use of vocabulary learning strategies and their success in vocabulary learning: a think-aloud protocol study

the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...

Adsorbent materials from paper industry waste materials and their use in Cu(II) removal from water.

This paper deals with the removal of Cu(2+) from water using adsorbent materials prepared from paper industry waste materials (one de-inking paper sludge and other sludge from virgin pulp mill). Experimental results showed that de-inking paper sludge leads to mesoporous materials (V(mic)/V(T)=0.13 and 0.14), whereas the sludge from virgin pulp mill produces high microporous adsorbents (V(mic)/V...
