Abstract
This paper describes the experimental setup for evaluation of pyrotechnic smoke compositions for anti‐laser and anti‐infrared roles using the continuous wave 10.6 μm CO~2~ laser (4 watt) and presents the results for a few pyrotechnic smoke compositions. The particle sizes of the aerosol from pyrotechnic smoke compositions were also determined using Quartz crystal Microbalance ‐ Cascade Impactor. Two smoke compositions containing hexachloroethane, anthracene/naphthalenee, potassium perchlorate and magnesium powder showed more than 97% attenuation of CO~2~ laser, whereas a composition containing zinc oxide, aluminium, iron oxide along with hexachlorocthane was least effective.

## Abstract The aims of this study were: (1) to compare the diagnostic efficacy for celiac disease (CD) diagnosis of serum determination of anti‐gliadin (AG) (IgA and IgG) and anti‐endomysium (AE) with that of anti‐transglutaminase (AtTG); and (2) to compare the accuracy of four different assays to
Two different monoclonal anti-A and anti-B and several different affinity purified Ulex europaeus lectin I reagents were evaluated and compared with conventional anti-A and anti-B sera and Ulex anti-H for serologic properties, in inhibition tests with secretor salivas, and in elution tests with bloo
